Book Review: "Hidden Figures" by Margot Lee Shetterly

I've recently read the book Hidden Figures by Margot Lee Shetterly. It weaves together the true stories of a few particular mathematicians, who happened to be black women (among a larger group of such female black mathematicians), who made extremely important contributions to the development of American warplanes in WWII and then spacecrafts during the 1950s and 1960s, including the crafts that took John Glenn to space and then the Apollo 11 astronauts to the moon. It highlights the skills of these women and their own personal lives, in conjunction with the broader social issues of that time.

The book is moderately long, but it is very well-written and engaging. I liked seeing the descriptions of these towns that flourished during the wartime years and the space race as bustling with life and energy, because with the trends of deindustrialization starting from a few decades ago, I haven't really been able to see descriptions such towns as much beyond shells of their former selves. This also ties in with the discussions of the military-industrial complex and how the formation of these towns during the wartime was a symptom of that phenomenon, which in turn meant that as wartime research facilities and organizations were often temporary, even if they hired black people, allowing them to economically advance to the middle class, those economic advancements became tenuous due to the temporary nature of such jobs, such that when the goal was met (whether it was winning the war or landing on the moon), those facilities would be closed and the employees there would be displaced with few, if any, alternatives available to them. Of course, pervading the book were descriptions of the explicit and implicit forms of institutionalized racism and sexism, whether at work in the form of barriers to career advancement or collegiality/free exchange of ideas, or in the context of daily life with respect to the civil rights movement, sit-ins, et cetera. Not only were those issues discussed in a broader context, but their impact on the specific protagonists of the book was detailed, showing how these women had to deal with so many struggles just to stay afloat while still trying to achieve the same goals to which any other family of any ethnicity would strive, namely, caring for spouses and children, putting food on the table, balancing work and family, and being able to raise children in a safe environment and educate them well; it really helped that the author so masterfully portrayed the mundanity of daily daily life for these women to show how stupid obstacles, like legalized segregation and institutionalized barriers to career advancement, could get in the way of the passion that these women had for STEM. It was also interesting to see that black communities like those in this book were acutely aware of how much more advanced the USSR and other communist countries were in terms of race and gender relations, and actively called out the US on its own failings in that regard (in the context of the US trying to ally with African and Asian countries that used to be European colonies), while these black women, despite being in the middle of such institutional bigotry, kept their heads held high and persevered in pursuit of their goals to contribute to STEM R&D. Related to that, it was also chilling to see how de facto segregation has persisted in education in many places through the US resulting in school facilities that in many poor places are no better than they were several decades ago, and also to see how many of the arguments for white parents sending their kids to private schools at that time were more explicitly about preserving racial segregation in education. Overall, I enjoyed this book thoroughly and would strongly recommend it to people for a clear and engaging account of how NASA and the social issues of the middle of the 20th century became intertwined.

Book Review: "Narconomics" by Tom Wainwright

I've recently read the book Narconomics by Tom Wainwright. It's an exposition into the economics of Latin American drug cartels, looking at them as businesses rather than mysterious criminal entities. In particular, it considers the competition versus monopolistic/monopsonistic behavior on the demand- & supply-sides, issues of global operations and outsourcing, diversification in products, cartel hierarchies versus franchising, public relations versus employee incompetence, and so on. Of course, as the drugs discussed in this book are illegal for the most part, there are other issues of dealing with the police and the government, whether through hiding, bribery, or warfare, and with enforcing things like non-compete agreements and franchise territories through violent means in the absence of legal recognition (where a court system could otherwise peacefully mediate such disputes). The aim of this book is to step back from the emotionally charged rhetoric of the "war on drugs" by seeing them in terms similar to legitimate businesses, and in doing so defeat the scourges of the illegal drug trade in the long-run through economically-minded legislation rather than ineffective brute force.

The book is not too long, quite accessible, well-written, and engaging to anyone with a high school-level understanding of microeconomics and an interest in issues surrounding illegal drugs. There are a few issues I have with the book though. One is that while the focus is clearly on Latin America, I would have liked to see at least some parallel discussion about the flow of drugs from Central/South Asia (particularly Afghanistan) to Europe and the economics therein, as that is mentioned a few times without further details. Another is that the last numbered chapter discusses legalization exclusively in the context of marijuana/cannabis, even though there is a discussion about the much narrower margin between safe and fatal doses for other drugs (especially heroin) compared to cannabis, which then raises questions about whether the legalization of marijuana is really meant to be a model for legalization/regulation of other currently illegal harder drugs; the epilogue addresses this point adequately with more nuance, but the structure of the final chapter still seems subpar for that reason. Finally, my biggest issue regards the discussions of how the operations of drug cartels in Latin America are influenced by how they can compete with the governmental "monopoly" on force due to unresponsive, complicit, corrupt, or ineffectual governments, and how cartels can compete with other economic opportunities through wages, protection, and other benefits. In particular, my concern is that the book acknowledges how legalization of drugs often economically incentivizes supply-side consolidation (as being outlawed necessarily limits how large drug operations can grow before attracting government attention), but in conjunction with other trends like offshoring of drug production too, it isn't clear how people in poorer Central American countries will further benefit; while the reduction in violence that would almost surely accompany restricted legalization of drugs is certainly a laudable goal, it is unclear whether the resulting economic opportunities, given the continuing poor governance and paucity of other good economic opportunities there, will really work to better the lives of those people, or whether the situation will devolve into large drug companies bullying small countries as in the banana republics of several decades ago (as discussed in the book) or tobacco or fast food companies doing the same to such countries today. In light of that, while the suggestions made in the book for improving outcomes of drug policy do seem like they would certainly help to some extent, I can't help but feel that the title of the epilogue, that economists make the best police officers, smacks of hubris. Apart from those issues, I'd recommend this to anyone interested in the subject.

Sexual Harassment, Power Dynamics, and Institutions

I've been thinking (read: armchair philosophizing without necessarily going into much depth) lately a bit about the notion of individuals shaping the interactions they have with other people versus the other way around, and the related notion of how individuals shape institutions versus the other way around. This idea has stuck in my mind especially in the context of sexual harassment committed by a professor against a student in my department (for a broad overview, see this article by Alanna Vagianos in HuffPost, and for a more detailed account, see this article by Allie Spensley in The Daily Princetonian; disclaimer: I know the student but not the professor), because of the complicated way that power imbalances between faculty and students intertwine with institutional tensions at large research universities like Princeton University. Follow the jump to see more blather from me about this.

On the Nobel Prize for Gravitational Waves

This is a short post about the news from last week, that the Nobel Prize in Physics went to 3 of the founders of the LIGO project that first observed gravitational waves. I was quite happy to see the news, for several reasons. One of the PIs, Rainer Weiss, is an emeritus professor from MIT, so there was the alma mater pride factor there; plus, that professor, along with the two other co-laureates, are all quite old, and it would have been a real shame if they hadn't survived to be recognized by the Nobel Prize committee for this incredible work, so it really was time for them to be recognized as such. From an applied science perspective, the amount of high-precision science and engineering they had to do, building laser systems, mirrors, and large-scale interferometers to measure atomic-scale and smaller displacements where quantum effects are important, has been amazing and will undoubtedly influence future technological development in those areas, even as gravitational waves themselves are at energy scales that are far too small to be useful in the near future (though people used to say that about quantum mechanics, and then transistors came about, so it's always better to be open to the possibility, while being mindful that this particular possibility is more remote).

Mostly, though, I'm thrilled to see this discovery being recognized from the perspective of fundamental science. My research is in fluctuational electrodynamics, which means that I deal with the propagation and scattering of electromagnetic fields at small length scales as they originate from quantum or thermal fluctuating atomic or electronic sources. Thus, all I think about on a daily basis is really electromagnetic interactions (and occasionally quantum exchange effects). But then, most physicists, with the exception of high-energy physicists (who study very short-ranged weak & strong interactions anyway), tend to make use of electromagnetism almost exclusively in their research, especially on the experimental side, as any spectroscopy, interferometry, and so on, would necessarily involve the propagation and scattering of light. In fact, if I think about how humans sense the world around them, vision is of course electromagnetic in nature, but so are hearing (detection of pressure waves caused by scattering of atoms and molecules in the air via short-range electromagnetic repulsion from atoms and molecules in the ear) and touch (short-range electromagnetic forces between atoms and molecules on the skin and a given surface), while electrical signals travel through neurons in the body by virtue of electromagnetic forces. Thus, in the context of sensing and understanding the world around us through truly long-range interactions, gravitational waves are fundamentally different, and it's weird to think that the interaction that keeps us on this planet can also be used in such a different way (i.e. propagating waves) to get information about faraway astronomical objects that wouldn't be available through purely electromagnetic means.

Starting as a TA

I figured I might post a short update on progress through my PhD. Through the summer and the start of the fall, I've been learning more about how to consistently incorporate molecular vibrations into descriptions of fluctuational phenomena, including van der Waals interactions and radiative heat transfer. It's been a very fun and interesting process, learning more about such fluctuational phenomena, revisiting and expanding on what I've learned in linear algebra and numerical analysis, and gaining a better understanding of the broader impacts that my work could have.
Also, two days ago marked my first day as a TA: I'm a TA for the graduate-level class ELE 511 — Quantum Mechanics with Applications. The discussions I've had with people during TA training and with the lecturer for this class, along with the preparation that I've had to do on my own and the questions that I've encountered from students so far, have really made me appreciate how much work it takes to prepare for teaching such classes and to be ready for students' questions, whatever they may be; plus, I've come to realize how annoying I must have been for TAs when I was a student, expecting them to be ready for literally any question, no matter how tangential to the material, and expecting them to be completely perfect in grading assignments, et cetera. To those TAs whose classes I took, I now have a better understanding of what your jobs were really like, and I thank you for putting up with me. I've enjoyed what I've been able to do so far as a TA, and I intend, with more time and practice, to become better at these variegated aspects of teaching as the semester progresses.

Book Review: "Genius at Play" by Siobhan Roberts

I've recently been able to read the book Genius at Play by Siobhan Roberts. It is a biography of John Conway from his high school days onward, covering a lot of his work on group theory, symmetries, number theory, and other fields; it does discuss the Game of Life but goes deeper into drawing out the evolution of his response to being solely associated with it, from joy to despair to resigned ambivalence. It also goes through various episodes in his personal life, and frequently switches between narrating recollections of past events and narrating the current events surrounding those recollections themselves. It shows what a whimsical, joyful, carefree, and gregarious man he has been when it comes to math, but while much of the middle section of the book makes this seem like his core personality, the beginning parts about him reinventing his personality after high school, the middle parts about others' (particularly Stephen Wolfram's) characterizations of him, and the end parts about his own feelings about it now (as an older man) make clear that the carefree part of his nature has been more of a facade to cope with his own ego & attendant insecurities.

I really enjoyed this book's progression through his life. It allowed me to once again experience the joys of seeing seemingly inconsequential math ideas that are easy to introduce but hard to truly explain to broad lay audiences, like I did in middle school with my fascination with numbers like pi and the golden ratio and the really random places they pop up. Plus, that juvenile whimsy combined with the human interest in reading about John Conway as a person, as well as my more mature recent interest in deeper philosophical questions, like the physical reality of mathematical theorems (whether they are invented by humans or discovered from the course of nature), or the nature of free will at the human versus subatomic quantum scales. The writing of this book really seemed reflective of John Conway's whimsical and sometimes scattered personality as well as of the people and environment surrounding him, painting a vivid picture of the man in context; I appreciated this to the same extent that I did Robert Kanigel doing the same for Ramanujan in The Man Who Knew Infinity, though in the latter case, Ramanujan seemed to be a rather shy person for whom information had to be gleaned from other sources (also because Kanigel wrote that biography many decades after Ramanujan's death), so Kanigel successfully painted the picture of the people and environment in India and the UK that shaped Ramanujan's personality and the course of his life. Overall, this was a really enjoyable book that went by quickly despite its length. Perhaps people who are slightly more acquainted with the basics of higher-level mathematics may enjoy it more than laypeople (and I would probably enjoy it more if I knew more math); nevertheless, I think the storytelling is quite engaging and accessible to a broad audience.

Book Review: "Our Declaration" by Danielle Allen

I recently got to read Our Declaration by Danielle Allen. It's a book that carefully goes through every word, sentence, and passage of the US Declaration of Independence from 1776 to argue that the broad notion of equality of all people, not just of white landowning males, was embedded in the text even then (and are not simply hopeful modern reinterpretations), and that such a notion of equality is a precursor, rather than subjugate, to liberty (the latter point being more commonly found in today's political culture).

The first few chapters seem rather distracting, because while it's nice to hear about the author's own passion for and history with this subject, those plus the next few chapters obscure the structure of the argument of the book; only when the author starts to analyze the text of the Declaration starting from the beginning of the first sentence does the book really pick up and the structure of the argument of the book actually become self-evidently clear (which is in some sense appropriate, given that the author herself took time to conclude that this methodical and structured reading of the Declaration is the correct one, so it would likely take others quite a bit of time to reach the same conclusion too). Most of the book is structured as a detailed, slow, careful, methodical exegesis of the text of the Declaration in the service of a defense of equality as a companion, not subjugate, to liberty; its drawing forth philosophical arguments and examples through only the text and the immediate history surrounding the drafting of the text, rather than focusing too much on the broader events surrounding that time, makes this a compelling alternative view of the Declaration, and seems carefully crafted to essentially be a liberal form of the originalism and textualism espoused by conservative jurists today (of the mould of Antonin Scalia), so for these reasons, I rather enjoyed the argumentative style of the book. While there are some parts of the book that may seem repetitive, given that the Declaration is covered from start to finish in order, the structure of the Declaration is almost like a fractal, and I appreciated the author making this structure evident: at many different scales (whether within a sentence or over the entire text itself), arguments emerge like that of people having the right to good government, that bad government does not respect those rights, and that people therefore have the right to alter their government in such cases.

There are a few main criticisms I have of this book. Throughout the book, the author argues that the essence of democratic government is that everyone has a qualitatively equal capability of judging their own happiness and considering their past and present to then judge their own futures, and that these come together through communication, giving the example of how the drafting of the Declaration required the revolutionary framers to rely not only on their own judgment but mostly upon the experiences of ordinary people from all of the American colonies. While the author presents this as a model of democratic information-collection going into democratic writing, I think the confirmation bias inherent in this approach is actually the main flaw of the book: the author tries to be too clever in separating qualitative from quantitative statements of equality, forcing her to sweep under the rug the issues of demagoguery & mob mentality overwhelming critical thinking (especially in conjunction with lack of education among large groups of people), as well as of different marginalized groups (whether poor white people, black slaves, or native peoples) perhaps feeling differently about continued British rule than those who were more willing to share negative feelings therein — these issues of mob rule, factionalism, and guaranteed rights would be fleshed out more in the Constitution, but they are not so self-evident in the Declaration as the author seems to suggest. Furthermore, the author argues that the dissonance between the lofty ideals of equality in the Declaration and the brutality of chattel slavery and genocide committed upon black and native peoples, respectively, is only due to the lack of willpower and desire at that time to bring those lofty ideals into concrete action applicable to black and native peoples, and that would come later; while that may be empirically true in a historical sense, from a philosophical standpoint it seems strange to give the revolutionaries such a pass on those issues given that the author argues in the same passage that the Confederacy was founded in the Civil War using words that made explicit the opposition to notions of equality in the Declaration (thus justifying a more expansive reading of equality from the Declaration even in those days), and given that the author takes care to point out the many drafts of the Declaration that explicitly speak out against chattel slavery and brutality in war. Additionally, people complain about those who say one thing and do another, exactly because those who put forth a call to action can be reasonably be expected to be most likely to take such action, so such dissonance makes one wonder whether such action is really feasible at all, or whether those calling upon others to act in some way but themselves act differently are trying to exploit a loophole (like dehumanizing black people to justify their continued enslavement as being consistent with the notion of human equality). Moreover, while the author does point to several drafts denouncing slavery to mitigate the reality of slavery in the face of the ideals of the Declaration, there seems to be no such argument with respect to women or native peoples, and the latter is especially troublesome given that the Declaration does make a few extremely negative references to native peoples (appropriating land, or fighting "savages").

Overall, while my criticisms do make me feel a little less certain about some of the specific arguments promulgated in the book, I did rather enjoy the methodical textual analysis with only the most relevant external information injected when appropriate. I should admit that I read through this book perhaps a little faster than the author wants readers to read it, but having gotten a new view of the Declaration, I'd be more inclined to reread both the Declaration and this book at a more deliberate pace at a later date. The arguments are interesting and clear, so I'd recommend this to anyone who's interested in the subject, especially those who may be feeling a bit down on the notion that the US is a country for them too. Follow the jump to see a few more of my specific thoughts about this book.

Book Review: "All the President's Men" by Carl Bernstein and Bob Woodward

I recently got to read All the President's Men by Carl Bernstein and Bob Woodward; although I had seen the movie many years ago, I hadn't gotten the opportunity to read the book until now, and I figured that with the current political situation in the US which so many are calling "Nixonian", it would be good to revisit one of the definitive works about a pivotal political scandal in that era. It's a documentation, from the perspective of the Washington Post reporters (the authors of the book), of the events and investigative journalism starting from the reports of the Watergate Hotel burglary and ensuing arrests all the way to the implication of President Richard Nixon and his top aides in engaging in illegal dirty campaign tactics to harm political enemies and subsequent illegal coverup tactics. It's a moderately long book, yet the smooth writing and structure of the details keep the narrative moving quickly. Although it has been a while, from what I remember, the movie focuses more on Bob Woodward's meetings with Deep Throat (the deep background informant who worked for the government), so it was nice for me to see the fuller picture of events from many other angles, showing that the meetings with Deep Throat, while important, were not necessarily the primary focus of any reporting events.

From the standpoint of this being a documentation of historical events, more than anything else, I was fascinated to see the (usually clever, sometimes questionable) extent to which reporters like Woodward and Bernstein would cajole agreements to meet and then share information on the phone, in person, or in writing with various people; it was like a miniature course in human psychology in the framework of various competing institutions with different power structures, and this was evident not just in the conduct of the interview subjects but also in Woodward and Bernstein themselves. That said, there were a few instances were their conduct went beyond the point of being questionable, becoming sleazy or even straddling the line of legality, and while these instances were discussed, they weren't given the same gravity as the corrupt behavior of government officials that they were uncovering; from their perspective, it makes sense as they would of course cast themselves in their own story as sympathetic protagonist reporters going up against a corrupt and vile group of people in a powerful institutions, but I would have liked to see more of this (though maybe other accounts from this era from other reporters would go further in depth). Overall, I really enjoyed reading this, and would recommend this to anyone interested in the political situation then or now. Follow the jump to see a few more brief thoughts about this book in the context of the current political situation in the US.

Long-Term Review: Linux Mint 18.2 "Sonya" MATE

Installed System: Main Screen + Xed
A little over two weeks ago, I made the decision on what Linux distribution to install and use full-time on my personal laptop. I chose Linux Mint 18.2 "Sonya" MATE, because I felt that while it could do a bit better for total newbies in terms of usability (as some usability features have regressed since a couple of years ago), it has been a reliable and known quantity for me, and I figured that if I could generally use the live session without much hassle, it wouldn't be too much of a stretch (no pun intended) to imagine that the installed session would likely be workable. As I've covered most of the experiences of installing and using programs and getting around the desktop in my review of the live session, this post will be relatively short, covering only the salient points of the installation and some of the changes I made after the installation. Follow the jump to see more.

Featured Comments: Week of 2017 July 9

I meant to write and post this yesterday, as I typically do this on Sundays. However, I was rather tired yesterday and forgot about it until today. Anyway, this past week, there were two posts that got comments, so I'll post four selected comments from one, and the single comment from the other.

Review: Debian 9 "Stretch" MATE

Reader Isaac Ji Kuo said, "Sluggishness is due to being a USB install. USB is far slower than a hard drive. LiveCD install partially compensates for this by using file system compression, but this still inevitably means sluggish delays due to decompression time. If you want to just see whether or not Debian is functional, a LiveCD is good. If you want to have some idea of its performance for a hard drive install, LiveCD will give you no idea. Flash works in Debian 9. I don't know precisely how it works, but every web site I've tried works with both Firefox and Google Chrome (normally I use Google Chrome, but it's not available in 32 bit so I was forced to try Firefox to use Netflix on my 32 bit computers). Anyway, I think it has to do with the PepperFlashPlayer." (Most of the comments were along these lines, with varying degrees of detail and civility.)
An anonymous commenter had this to say: "Testing live image from USB/DVD and complaining about sluggish delays is bit silly. Unless you test some Puppy/Puppy like distro that loads in ram. Debian live images are used for only one purpose, to see what it can offer with different desktop environments. It is not even recommended to install from those live images, even if that option exists. As for flash, no it does not work out of the box with Debian. And package for flash in Debian is unusable, its maintainer is missing in action. On google chrome flash comes integrated with browser. For Firefox it can be installed easily by downloading it from adobe site, unpacking it and moving libflashplayer.so to the /usr/lib/mozilla/plugins/. Downside of that is that you must manually repeat procedure whenever adobe updates flash."
Reader CFWhitman shared, "In my experience Debian is faster in regular use than any version of Ubuntu or Mint. When you have lots of resources, it's just as fast as Lubuntu or LXDE. When you start to run short, it tends to be faster, at least as long as you are running the same desktop environment. When I have hardware that's too weak for even Lubuntu to run well on it, I switch to Debian. I run Debian 9 on a ten year old netbook with an Atom N270 32 bit processor and 1 GB of RAM. If you had problems with speed I have a lot of trouble believing it's a problem with Debian 9. Your USB drive would seem a more likely culprit."
Another anonymous commenter had the following tips: "Other distributions optimise for the liveCD demo, but Debian optimises for long-term use ;-) For a Debian distribution that uses the Mate Desktop and is optimised for liveCD use I'd give Parrot Security OS a try. And yes, I will read your review! That said, I'm about ready give give up on reading "reviews" that are in effect clickbait...eg: just a liveCD demo that is not of what it's like to use for a week or two. LiveCD/USB/etc should be in the title of the page imho. To be fair, sometimes the installed system can be slower than the live one due to background processes like file indexing daemons. ex: Nepomuk and aKonadi. How a distribution configures such things in an actual installation says more about the experience of using it and more about the values of the project than any liveCD."

Review: Linux Mint 18.2 "Sonya" MATE

Reader Steve said, "Please give Debian the benefit of the doubt. It has a huge ecosystem and is ported to dozens of different architectures and envirionments. The Debian developers and maintainers do an amazing job of keeping the various versions to have the same look and feel as much as possible. I used to think that two years was an awfully long time to prepare a new version, until I researched the Debian web sites to see what had to be done." (This was more in response to the previous review, as I had referenced it in this review.)

Thanks to all of those people for those comments. I don't have anything particularly planned for this week. However, I did end up installing Linux Mint 18.2 "Sonya" MATE on my laptop's hard drive, and have been using it for over a week now. Given that, I'll probably have a short post with some notes about installing and using it next week. Anyway, if you like what I write, please continue subscribing and commenting!

Review: Linux Mint 18.2 "Sonya" MATE

Main Screen + Linux Mint Menu
The quest for a replacement Linux distribution for Linux Mint 13 LTS "Maya" Xfce continues. With this post comes a review of the latest MATE edition of Linux Mint. Especially for regular readers of this blog, Linux Mint needs no introduction. I will just say that with the latest point release, it seems like the developers have put more polish into the distribution, including their new set of "X-apps" meant to work across MATE, Cinnamon, Xfce, and GNOME, avoiding the pitfalls of more DE-specific applications. I want to see what has changed since my last review and to see whether this would be suitable for installation and daily use on my laptop. To that end, I made a live USB system (again, on my new SanDisk Cruzer USB flash drive) using the "dd" command. Follow the jump to see what it's like. Note that I'll frequently reference that previous review, noting only changes and overall important points as needed.

Review: Debian 9 "Stretch" MATE

It has been about 2 months since the support cycle for Linux Mint 13 LTS "Maya" ended. Since then, I haven't been able to update Mozilla Firefox or Adobe Flash, and concurrently, I haven't been able to use the latest versions of Google Hangouts or Skype, the former of which I already cannot use to the fullest extent, and the latter of which I am still somehow able to use but am counting the days when that will end too. Given that, it is urgent that I upgrade the Linux distribution that I use soon, so today, I am trying Debian.

Debian is a rather old distribution, being among the first to use the Linux kernel. It is known for its very conservative release policy for distribution and package versions, as well as its strict policies regarding free versus proprietary software; as such, it is known to be a stable base (and has been the original base for Ubuntu and its derivatives) for desktop and server environments, though while it is not supposed to be a piece of cake to configure and use, it does come with decently-configured generic DEs and other software to start. I figure that I have accumulated a bit of experience with testing and configuring Linux distributions, so that I may be able to install and configure things to my liking even if they aren't present by default.

I tested the 64-bit edition on a live USB made from a live ISO file using the command "cp", which Debian recommends. Additionally, it is worth noting that this is the first review that I'm doing on a new SanDisk Cruzer 8 GB flash drive (as my previous SanDisk Cruzer Micro 8 GB flash drive, which I got 8 years ago, seems to have stopped working reliably, which is why I haven't used it for reviews in the last few months, and the flash drive that I had been using in the meantime, a generic 4 GB unit which I got for free from a career fair several years ago, stopped working after a "dd" command failed). Follow the jump to see what it's like. (Also, I apologize that there are no pictures; I stupidly forgot to upload them, and by the time I exited the live session and restarted my computer, it was too late.)

Book Review: "The Big Short" by Michael Lewis

I was recently able to read The Big Short by Michael Lewis. Even though there were quite a few details that went over my head, it's an interesting, compelling story about a few specific people who essentially shorted (in other words, bet against) the entire US financial system and ended up "winning" in the 2008 financial crisis. I knew the basic details of how mortgage-backed securities were packaged and repackaged to get high ratings from well-known agencies, even though the underlying instruments were high-risk mortgages given unscrupulously to poor people who were likely to default; that said, I found incredible just how much fraud was being perpetrated, like laundering credit scores based on essentially nothing, or ripping off low-income people with false or misleading interest rates. Also, many financial models seemed to assume no underlying information and total lack of correlation among various investments, assets, or liabilities, even this was obviously untrue: subprime mortgages bundled into financial instruments were highly correlated by underlying economic indicators, and companies' fortunes could often be predicted much more accurately even with publicly-available information (like with Capital One's fortunes depending on regulatory judgments against it), yet these models often still naïvely and nonsensically assumed Gaussian distributions for such events.

Coupled with that ignorance of information in financial modeling seemed to be an intentional lack of transparency in the market for these complex securities and other financial instruments. Typically, enlarging a risk pool would seem to produce better outcomes throughout the market, but here, the mirror image of that was happening: more and more people were being exposed to risk, and that risk was being multiplied based off of essentially nothing tangible (often simply camouflaged through clever names as comprising diversified assets), yet large Wall Street firms were making money off of that for years before the whole system collapsed. On a related note, some people have claimed that short-sellers are beneficial to the market by signaling that certain trading practices should stop as they are too risky, yet as far as I can tell, this only works in an idealized world where information and people's decisions are transparent to everyone, whereas the whole point is that the short-sellers and those selling risky financial instruments were all trying to one-up each other in a cloud of opacity and obfuscation so that they could make their big money (which is what really happened).

Overall, the book is quite engaging and well-written. As I mentioned earlier, there are a lot of subtleties, nuances, and jargon that went over my head, but the narrative and salient points are clear enough to a layperson; if anything, the technicalities simply add to the authentic feel of what one of those short-sellers must have been thinking during those years leading up to the 2008 financial crisis. It is important to note that the focus of this book is the financial crisis and the years leading up to it, from the perspective of the finance industry/Wall Street; it does not really touch upon the broader economic trends in the US leading up to that point (except for specific trends that tie into the discussions of specific mortgage-backed financial instruments), and it does not discuss the recession per se. With that in mind, I'd recommend this to anyone who is interested in the subject.

Second Paper: "Unifying Microscopic and Continuum Treatments of van der Waals and Casimir Interactions"

My second paper has been published! It is in volume 118, issue 26 of Physical Review Letters, and an older preprint of it is available too for those who don't have access to academic journals (it has all of the same figures and ideas, though it is missing a few sentences of further explanation as well as a couple of new citations that were inserted for the final publication). As with my first paper, in the interest of explaining these ideas in a way that is easy to understand, I am using the ten hundred most used words in English (except for the two lines that came before this one), as put together from the XKCD Simple Writer. I will use numbers sometimes without completely writing them out, use words for certain names of things without explaining further, and explain less used words when they come up. Keep reading to see what comes next.

Book Review: "Cosmopolitanism" by Kwame Anthony Appiah

I've recently been able to read Cosmopolitanism by Kwame Anthony Appiah. When I first picked it up, I thought it might be an interesting take on the issues of multiculturalism and immigration that Western societies have had to deal with over the last 2 decades (considering that this book was published in 2006). It actually turned out to be a bit different than I expected, being instead a more abstract philosophical work that lays out the arguments for a certain sort of cosmopolitan worldview and manner of engaging with other people, with these arguments being based on somewhat more abstract discussions of the histories of nations, cultures, and peoples. In particular, the author discusses how cultures have diffused throughout space and time and how people are capable of engaging with different issues and other people from across the world in an intelligent and active manner, so the framing of issues like cultural imperialism/theft or charity for the poorest around the world may end up being counterproductive in the long-term; additionally, the aim of conversation and engagement with strangers should be to reach a mutual understanding and (ideally, though this depends somewhat on the topic at hand) respect for different culture-specific values, because persuasion of people to change such culture-specific values is typically [though not always] a fool's errand. I realize this brief summary doesn't really do the book justice, because it is a rather dense book (at least for a layperson like myself) with so many different issues discussed at varying lengths and levels of abstraction.

Overall, there are a lot of arguments that seem disconnected, especially the anecdotes of his family or his childhood in Ghana (though those were nice to read), and there seem to be a lot of philosophical subtleties that may well have gone over my head, but while each chapter is a nice self-contained explanation of an aspect of cosmopolitanism, the overarching message seems rather muddled (especially comparing the last chapter to everything before it). There are other issues that I have with the book that I'll detail after the jump, but more broadly, I was somewhat disappointed by the ease with which I could use the author's own terms and arguments against the book. That said, I do agree with one main theme, and that is of respectfully engaging with strangers by critically examining "thick" beliefs on their own terms and as they arise from other "thick" & "thin" beliefs (to be explained after the jump), in order to find common ground while also understanding and respecting where differences arise; this is similar to what I learned from the last student-led discussion I attended at the Day of Action on campus in March. I suppose people who are interested in this sort of thing would be drawn to this book anyway, but I wouldn't really recommend this otherwise. Follow the jump to see more of my thoughts on this book.

Book Review: "Brave New World" by Aldous Huxley

I generally don't read works of fiction, as I don't have as much interest in them as I do in well-crafted nonfiction works, but Brave New World by Aldous Huxley is one of the classics of dystopic science fiction; in particular, many comparisons have been made to Nineteen Eighty-Four by George Orwell, with the latter surging in popularity in the last few months in the context of the current political climate in the US, so I figured I might give this one a read instead. This book is set in a time where society is explicitly stratified into castes and everyone is conditioned, through physical, chemical, and psychological means from [artificial] fertilization through death at age 60, to behave in ways that would never lead them to question their roles in society; this is further helped by the omnipresence of a pleasurable drug called soma and by the omnipresence of this very conditioning, such that social ostracism is feared perhaps above all else. With that in mind, the main story primarily involves two characters, one named Bernard Marx who is born and raised in this society but finds himself dissatisfied with the society and his role in it, the other named John the savage who is born to a woman (named Linda) outside of this society and becomes repulsed after understanding the superficiality of the existence of members of that society.

The initial parts of the story seem to drag a little bit as it isn't initially clear to which character the reader's attention should primarily be drawn, but after the introduction of Bernard Marx, it becomes much clearer that the initial parts paint the setting of this world to make it clear why Bernard Marx is out of place. Additionally, in terms of movement of the narrative, the extended dialogue between John the savage and the controller Mustapha Mond drags a little, but it provides a fascinating glimpse into the author's true view of such a futuristic world. What I found most interesting is that both Bernard Marx and John the savage keep trying but failing to escape the oppressive social confines of their world, though the issues at play are different. Bernard Marx feels socially isolated due to his short height relative to his upper caste and due to his (perhaps related) desires to have time from himself, away from the rest of society. However, his psychosocial conditioning is fairly thorough, such that even when he visits the tribe of savages and has a chance to live a simple and isolated life among them, he chooses instead to bring John the savage as well as Linda back to the main society in London so that he can gain credibility in that society that he finds hard to come by; when John the savage rejects further gawking visitors (which reflects poorly on Bernard Marx, being the custodian of John the savage), rather than joining John the savage in solitude, Bernard Marx becomes despondent about his renewed feelings of alienation and ostracism from society at large. This deepens near the end of the book, when he is exiled to Iceland; his thoroughly conditioned worry about social alienation overcomes any excitement he may have felt at realizing that he would be among high-caste misfits like himself instead of in the superficial society for which he ostensibly does not care so much. Likewise, John the savage is initially delighted by what he sees after traveling from his tribe to London, but having been raised and conditioned outside of that society, he is disgusted by the superficiality, free love (though that may have more to do with his early childhood trauma of seeing his mother, who was brought up in the society, attempt to practice free love with the men of the tribe, consequently leading to his and his mother's ostracism from the tribe by the women and children of the tribe, respectively), and inability to find solitude in the main society. Yet at the end of the book, when he attempts to escape and live an ascetic penitent life outside of the city, the other members of society relentlessly hound him as an exhibition for their amusement; even at the very end, when he takes his own life, his limp hanging body is seen as another cheap spectacle, so even in death, his earthly remains cannot escape the superficiality of that society. Overall, I'd recommend this book for anyone interested in this sort of thing. Follow the jump to see more discussion of my thoughts about how this relates to today's society in the US (disclaimer: this is coming from a lay observer of American politics and society, so don't take anything too seriously; moreover, I'm sure that many of these observations have been made in the past by various people at different times).

Book Review: "Red Notice" by Bill Browder

Recently, I was able to read the book Red Notice by Bill Browder. It is a detailed exposition of his career in finance, specifically his interests and investments in Russia (as well as other parts of Eastern Europe earlier in his career). He discusses how he and his business partners were able to find so many amazing investment opportunities in Eastern Europe after the fall of the USSR just because few other people had seriously considered those countries for investment. This leads to his company being the victim of fraud perpetrated by corrupt government officials and oligarchs in Russia, and once his business partners and lawyers come under threat from governmental and extrajudicial shakedowns, he turns his focus away from his investment company and toward the broader issue of human rights abuses in Russia, thereby going from a friend to an enemy of Vladimir Putin.

The book, though it may seem long due to the page count, is a fast-paced, gripping tale of intrigue and suspense, reading so much like a James Bond-esque spy thriller novel that it is easy to forget that this is all a true story. It was also enjoyable for me to read this because I hadn't really given much thought to the issues of economic inequality, oligarchy, and investment in Russia after the Cold War, and I certainly hadn't considered it from the perspective of a financier who could make both friends and enemies in high places.

What's more interesting to me is to consider that at the beginning of his career (as the story is mostly a chronological account of his career), his actions are essentially amoral, being driven primarily by greed; his exposure of the fraudulent practices of corrupt government officials and oligarchs in Russia was driven not by high-minded morality but by his desire to ensure the success of his company and to do right by his investors/business partners who were counting on him. In a sense, there may have been a weird tribal morality that one could associate with his close kinship with his business partners and his initial desire to push forward with exposing such corruption despite the high personal and business risks of doing so. This is further justified by considering that his focus turns away from his company and toward broader issues of human rights abuses when his business partners and lawyers start becoming targets of extrajudicial shakedowns, most notably including Sergei Magnitsky, whose cruel and inhuman torture and neglect before even going to trial (which culminated in the insane posthumous show-trial of Magnitsky in Russia) made him a cause célèbre in the US and EU, leading to the passing of laws recognizing his work and financially sanctioning those in Russia involved in his torture and murder.

That said, he shows himself throughout the book as believing in the ideals of the rule of law and justice while simultaneously understanding that these are hard to come by in Russia, and as a result, he portrays himself as having some moral core that overrides business and personal considerations as his friends come in danger; it is only his initial naïveté about Putin that makes him initially think of Putin as an ally in the crusade against the oligarchs, and these illusions are shattered quickly enough when Putin co-opts the remaining oligarchs and enriches himself in the process. By contrast, he shows the oligarchs to be thoroughly corrupt in their quest for material enrichment and their ability to shamelessly lie, cheat, steal, and hurt people to that end; they operate at a totally different level of amorality. Of course, this depiction is his own, so it's not surprising that it would elevate his own moral standing, potentially at the expense of others, and the same can be applied, for example, to his rather negative portrayal of John Kerry as desperate to hang onto as well as enhance his existing power; with that in mind, his story seems somewhat more credible to me given the independent validation by all of the different people and news organizations of his accounts of Russia. It's worth noting too that the verb "corrupt" comes from the Latin word meaning "break from within", and can also mean "rot" or "spoil". In this case, the oligarchs may have some thin veneer of seeming morality (if that), but this is quickly eaten away by having a lot of money and power, revealing only the atavistic amoral lizard brain at the inner core; by contrast, the author seems to maintain some moral core throughout the story, and while he is initially motivated by amoral greed at a surface level, once things hit him in a deeply personal level, that surface is stripped off (though again, it is necessary to bear in mind that this portrayal is the author's own). Overall, this book is a very interesting and intriguing read, and I'd recommend it to pretty much anyone.

Nuanced Déjà Vu in Microsoft's Desktop Monopoly

When I was in late high school, which was in the early days of this blog, I had recently switched to Linux and was essentially an evangelist, singing its praises and loudly cursing the misdeeds of Microsoft with respect to the desktop market; many of my blog posts at that time were in that vein. In the nearly 8 years since then, I, my blog, Linux, Microsoft, and the consumer device market have all evolved and matured: I've become less evangelistic and more realistic about many things (or so I'd like to think), my blog has correspondingly shifted focus in various ways, Linux distributions have become less of a "wild west" than they were 8 years ago and have gained more support for popular things like proprietary video drivers and game platforms like Steam, Microsoft has been more open about supporting free and open-source software initiatives, and the consumer device market has shifted much more toward mobile devices, including smartphones and tablets which are very different from the desktops, laptops, and netbooks of 8 years ago (the latter of which doesn't really exist anymore as it once did). That said, I recently read a post on Slashdot (original article by Brian Fagioli of Betanews) about how Microsoft is locking the configuration settings for changing the default browser (Microsoft Edge) and search engine (Bing) choices in Windows 10 S, which is its version of Microsoft Windows 10 designed for lower-end hardware used in schools. For the sake of old times, I thought it might be nice to post about it, but hopefully with a bit more nuance than what I was capable of 8 years ago (and with the benefit of having seen the last 8 years of intervening technological development).

Book Review: "Weapons of Math Destruction" by Cathy O'Neil

An anonymous reader said, "I had one question. Since algorithms may have access to the internet, (not controlled by the government or any particular single body), I imagine it would be extremely difficult to minimize their abuse or misuse. I hope precautionary measures such as new government or private bodies or maybe benign algorithms will deal with this issue in the future. Does the author talk about such measures ? Also, it seems that there is a lot of unrest regarding AIs these days. People like to imagine situations where an AI designed with a rather innocent goal of calculating 'pi' with a significant precision exterminates human race, sets on a conquest of the entire galaxy just to calculate 'pi' but for reasons unfathomable. Does the author talk about misuse of algorithms by AIs ? Although I am asking about the book, I would be more interested to know your personal views on these. :) Thank you."

Thanks to that reader for that comment. I don't have anything particularly planned on this blog for this week, but I may have a distribution review next week. Anyway, if you like what I write, please continue subscribing and commenting!

Book Review: "Weapons of Math Destruction" by Cathy O'Neil

I've recently read Weapons of Math Destruction by Cathy O'Neil. It is a short but dense exposition into the various ways that computer algorithms can determine the courses of people's lives and exacerbate existing societal inequities and biases/prejudices, in areas like education, civic engagement, education, health at the workplace, and many others. It argues that while many algorithms used in big data can be used for good, many instead widen inequalities and reinforce various cycles of poverty because of their opacity, lack of accountability, poor use of statistics, and lack of critical examination by those in charge (who instead use results and predictions generated by such algorithms to fire workers, deny opportunities to potential employees, financially prey on poor people, and so on, making such predictions self-fulfilling prophecies as only confirmatory data is fed back in); in particular, many of these algorithms and models use questionable proxies to predict certain attributes or behaviors (especially when the desired attributes are hard to quantify but the proxies are easy), these models are rarely transparent in what inputs are collected and how they are manipulated to produce outputs, and further research and fine-tuning are rarely performed to correct models that most humans would recognize produce incorrect results (but which computers would miss). It concludes that extensions of existing regulations on use of health and financial data are needed to curtail the misuse of such algorithms, and that simultaneously data scientists need to be scrupulous about the ways that their work is used and developed.

I rather enjoyed reading this book: it's pretty fast-paced, yet gives many detailed examples of the abuse of these algorithms to form a compelling narrative. Additionally, it in many ways follows the book The Attention Merchants by Tim Wu (which I have previously reviewed), because as that book shows the various ways that companies collect and sell customer data, this book shows the various ways that data can be used for the benefit of those companies (even if that works against some of those customers). There are only two issues that I have with this book. One is that the few times that politics comes up, the author's political bias (in favor of liberals in the US) is obvious; perhaps this is just due to the nature of the author's passionate crusade against abuse of algorithms and for institutional action uplifting poor and marginalized people, as that would necessitate regulation of such mathematical instruments, which would be (and has been) loudly opposed by large corporations maintaining their short-term profits and long-term status quo through these algorithms as well as the conservative politicians that they support. The other is that there aren't too many examples of big data and related algorithms truly working toward greater socioeconomic equity, especially when such algorithms are finding patterns that wouldn't be found by humans; while I get that the author is trying to build a brief but dense narrative warning against the excesses and abuses of such algorithms (as she professes herself to not be a big data evangelist), I would have liked to see more nuanced examples of proper uses of big data, because as this book stands, it seems just as one-sided/polemical as uncritical big data evangelism. Overall, I certainly feel like I got a better sense of the potential dangers of unchecked and uncritical use of algorithms to shape the economy and society. Plus, now that I'm about halfway through my PhD, I've started to think more about the sorts of jobs that I'd like to take after I finish. I've decided that I don't want to go into finance because (as mentioned in this book too) I'm not comfortable with playing with other people's money, as it is too easy to be seduced by mathematical simplicity and elegance into doing questionable things. That said, one thing (among the many) that has caught my fancy has been studies of policy problems (especially as related to STEM fields, but as they affect ordinary people); however, the story in this book about the role of the Mathematica Policy Research company in developing the arbitrary and statistically unsound metrics for evaluating teachers in DC public schools has made me realize that I'll need to make sure if I end up joining a policy research organization/consultancy/think tank that the organization that I join is responsible and transparent about the data that it collects and processes as much as possible.

Review: Manjaro Linux 17.0.1 "Gellivara" Xfce

An anonymous reader said, "Manjaro is quite a bit more stable than other rolling-release distros, as they delay packages from Arch for a couple weeks to test them for stability/compatibility before updating the Manjaro repos."

Thanks to that reader for that comment. This coming week, I will have another book review out. I was hoping to do a Linux distribution review, but I had trouble booting it, so I'll have to wait until next week to review a different distribution (which will hopefully provide more success).

Review: Manjaro Linux 17.0.1 "Gellivara" Xfce

This is the next installment of my series of reviews to determine which Linux distribution I can use to replace my current installation of Linux Mint 13 LTS "Maya" Xfce on my personal laptop. The (not strict) criteria that I am considering are that the distributions should be well-known, which is reflected to some degree in DistroWatch rankings, as this implies that the distribution may have official or strong community support for popular proprietary packages; additionally, the distributions I consider should preferably have MATE or Xfce editions (though I'm open to other DEs as well), and should have a long (more than 3 years from now) support cycle or use a rolling-release support model.

Main Screen + Xfce Whisker Menu
The current distribution I am trying is the latest Xfce edition of Manjaro Linux. It is a rolling-release distribution that was formerly based on Arch Linux, though it still uses the Arch User Repositories (AUR) for many packages that the distribution maintainers do not officially test. It also has an official KDE edition, as well as community-supported editions for other DEs. I tested the 64-bit version (though a 32-bit version is available too) on a live USB made through the "dd" command. (This time, I used a USB stick that I have never used before, to avoid the issues seen in my recent review of openSUSE with my previous aging USB stick that I have been using for reviews for the last 8 years.)

Book Review: "Atomic Accidents" by James Mahaffey

I've recently read Atomic Accidents by James Mahaffey. It's a fairly long and detailed exposition into accidents involving civilian nuclear power or military nuclear weapons in the US, UK, [former] USSR, Japan, and elsewhere. The author goes into quite granular detail with respect to the history of a certain weapon or civilian site, the timeline of the accident, and the aftermath; with each, he summarizes the lessons that were learned (or should have been learned but were not). After an introduction showing how nuclear accidents are quite similar in many respect to railroad accidents, the first few chapters go into the development of nuclear technology through WWII and the accidents along the way. The middle section of the book goes into knowledge gained about the occupational hazards of employees at power plants, the risks of transporting nuclear material by airplane, and related ideas. The last few chapters are about more recent accidents in Three Mile Island, Chernobyl, and Fukushima, ending with an assessment of the current state of nuclear power.

As a layperson with respect to the field of nuclear engineering, I think this book may be best suited for experts and other people with a serious interest in the field; for laypeople, the first few and last chapters are interesting, but reading through the middle sections became somewhat tiresome, as the technical details and jargon were a bit hard to follow, and the structure of the stories of the accidents became rather repetitive. The author does discuss issues of fear/hysteria in the general public with respect to nuclear accidents, yet the [seemingly contradictory] combination of the overall discussion of nuclear accidents in gritty detail along with some relatively cursory words of support for the safety and efficacy of nuclear power at the end means that this really is for experts who rationally understand the full historical & current contexts underlying nuclear power. Additionally, as a side note, the author briefly mentions India's nuclear program twice, noting that the Indian government broke a promise to Canada to not turn an imported reactor design toward weapons development, and that nuclear power plants there have had spotty safety records; while I am all for calling out entities that are cavalier about these issues, I found the author's word choice to be unnecessarily condescending toward India in a manner reminiscent of British imperialists justifying the subjugation of India in order to "civilize" the "savages". That aside, as noted earlier, I would recommend this book to those with a serious interest in this subject.

Review: openSUSE Tumbleweed GNOME Snapshot 20170329

Reader msian_tux_lover said, "I think you missed the point and objectives of Tumbleweed - it isn't meant for beginners and more for tinkerers and hobbyists i.e. people with average or higher know-how of Linux like yourself for instance; that is why Tumbleweed is a rolling distro with newest/er versions of packages rather than a more fixed/controlled versions of most packages like LTS versions of your favourite Ubuntu/Mint platform. I have to agree that openSUSE Tumbleweed needs to be more polished (I am thiking of a similar edgy distro like Fedora but then again they aren't a rolling distro, although you 'could' upgrade the distro using fedup - a bit of a hit and miss there), but that is what openSUSE Leap is doing - a hybrid distro with core stuff from SUSE Linux Enterprise (SLE) with community userland apps. Tumbleweed can be rough round the edges - but it is running fine on my low end Acer notebook."

Thanks to that reader for that comment. Now that I'm done with my conference and the pace of work has settled back to normal, I can post more in this blog. This week, I will have another Linux distribution review as well as another book review out. More Linux distribution reviews are to come through this month and next month as I continue to search for a replacement for the distribution currently on my laptop.

Review: openSUSE Tumbleweed GNOME Snapshot 20170329

For the last 5 years, I have been running Linux Mint 13 LTS "Maya" Xfce as my main OS on my laptop. Its support cycle is only 5 years long, so its end-of-life is fast approaching (within a month). This has spurred me to seriously start looking into replacements/upgrades. In the interest of having an open mind, I don't necessarily want to lock myself into sticking with Linux Mint; while I may still be biased toward the Ubuntu/Linux Mint family, the collection of minor issues in the latest releases of Linux Mint may actually make me more open to other alternatives. However, I'm probably not going to go with some small one-person distribution, especially if the community around that distribution is small and it doesn't have officially-supported packages. My criteria for considering a distribution are that it should have either official support for Skype and Google Talk (both of which I use regularly) or it should have a large enough community to make unofficial support viable (through the implication that the distribution will last a long time); related to the last point, I expect the support cycle to be as long as possible, and in particular, to be more than 3 years. Additionally, while I am not completely opposed to KDE, my most recent interactions (in my most recent distribution reviews) with KDE 5 have left me somewhat less than impressed, so when possible, I will try to stick to MATE/Xfce when possible, thanks to my familiarity and confidence with their tools, ability to recognize peripheral devices, et cetera. Additionally, because I'm seriously trying to test aspects of these distributions for my daily use, I'm going to touch upon a few other things beyond what I might write for a typical distribution review.

With that in mind, my first test subject is openSUSE Tumbleweed GNOME. I've tried openSUSE before, but it has been a while since the last time. Additionally, its support cycle is only 3 years, but it does have a rolling-release version called Tumbleweed, so I figured I might try that. I created a live USB of the 64-bit ISO using the "dd" command, as recommended on the website. Follow the jump to see what it's like.

My Time at the 2017 APS March Meeting

This is just a quick update from my graduate studies. In the middle of March, I was able to attend the 2017 APS March Meeting in New Orleans, Louisiana; this is the first conference that I have attended in any capacity. I had a ton of fun being able to travel there and meet with old friends, collaborators whom I had not yet met in person, and other people that I didn't know but who have been working on similar things to me; it was great being able to discuss interesting potential project ideas with them. Going to many talks was also cool, giving me a good sense of the state of my field and the sort of work that other people are doing, though in many respects, I honestly feel like I learned more just from talking with people at length in more informal settings. Finally, the highlight for me was getting to present my own work and seeing the interest that many people took in it: I was presenting a semiclassical electromagnetics approach to van der Waals interactions between molecules and larger bodies in a session dominated by density functional and atomistic long-range many-body approaches to van der Waals interactions solely in [large] molecular systems, so I was truly gratified to see that members of the audience saw value and significance in what I've been doing, especially given how different my talk was from those that came before and after it in that session. Overall, I had an amazing time, and I hope to be able to attend other conferences, both similar to this as well as more specific to my research, during my remaining time in graduate school.

Book Review: "How Everything Became War and the Military Became Everything" by Rosa Brooks

I've recently read How Everything Became War and the Military Became Everything by Rosa Brooks. It's a moderately long book about the institutional culture of the military, the historical and present perceptions of the military and its relationship with peacetime society, the evolving notions of war & peace, and the issues facing the military in today's domestic politics and international uncertainty. The thesis of the book is that while societies have historically tried to neatly separate war & peace spatially as well as temporally, such a dichotomy is rarely clear in practice, and the state of low-grade perpetual war in which the US is currently engaged, especially with regard to the adversaries we face, is in many ways surprisingly similar to the history of wars before the emergence of well-defined nation-states in Europe; moreover, issues like mission creep and a shifting political & financial emphasis away from civilian foreign engagement toward military engagement, in conjunction with adversaries having access to technologies and the fruits of globalization that allow them to attack the US from afar with unprecedented ease, has caused the military to take on roles for which it was not built (in the form in which it exists now), further blurring the lines between civilian versus military roles and war versus peace.

I really enjoyed reading this book overall. Although it's a little longer, the writing is clear and accessible, and the stories & anecdotes interwoven with more formal reports & studies make the progression of the book engaging. Additionally, I feel like the author's background of having grown up in an anti-war family and still retaining a somewhat skeptical eye with respect to military action/growth while also having worked in the Pentagon and in similar roles at other institutions for as long as she did lends her credibility when discussing the subtleties & nuances of the US military, its foreign policy, and its institutional culture. Overall, I highly recommend this book to anyone with even a passing interest in current US affairs; follow the jump to see a few other thoughts about this book.

Book Review: "The Victorian Internet" by Tom Standage

I recently read The Victorian Internet by Tom Standage. It's a brief history about the technical development of the telegraph, developments in telegraph operations, its uses, its rise, and its eventual decline. It particularly goes into the various ways that optical and then electrical telegraph systems were developed by different independent inventors, the difficulties in laying cables for long-distance telegraphy, and the ramifications of the telegraph for business, politics, military actions, newspapers, and day-to-day communications among ordinary people (despite the usual hype of that time about how instant communication would bring people together and effect world peace), comparing these issues to the issues people care about with regard to the Internet, given their similar network structures (though do note that this book was written in the late 1990s, so the author couldn't have even imagined things like Google, Facebook, or Twitter at that time). It's a short book that is a fairly engaging and fast-paced read throughout, so I'd recommend it; my only minor complaint is that the discussion of messaging through pneumatic tubes, while certainly relevant to the chronological history of the telegraph, seems to be a bit of a distraction from the main point of how relatable the 19th century telegraph system would be to users of today's Internet. Follow the jump to see a few more points about the book.

Review: KDE neon 5.9.1

It has been a while since I've done a review of a Linux distribution. Lately, I've seen a few reviews of KDE neon (the second word being intentionally written in lowercase), and some of them have praised it as being much better than Kubuntu (the traditionally KDE spin of Ubuntu). That got my attention, so I figured I should check it out.

Main Screen + Kickoff Menu
KDE neon is essentially a showcase of the latest and greatest version of KDE, packaged atop the most recent LTS release of Ubuntu. It specifically does not officially support any other DEs (though of course users can try as they like), and it is meant to provide the stability of the Ubuntu LTS base in conjunction with the newest features from KDE. It has several versions available, depending on how adventurous one feels in using new software; some of the versions claim to be made for "everyday users", which I take to include Linux newbies, so as usual, I will evaluate this distribution from that perspective. In particular, I downloaded the User Edition (not the User LTS Edition, which features the latest LTS version of KDE, though all editions feature the latest Ubuntu LTS base) and wrote it to a USB via UnetBootin.

Book Review: "The Attention Merchants" by Tim Wu

Originally, this post was supposed to come out a week ago, as a Linux comparison test between BunsenLabs Linux and CrunchBang++ ("#!++"), two quasi-official successors to the now-defunct CrunchBang ("#!") Linux distribution. Unfortunately, neither of them booted in a live USB. For that reason, this post is now a book review of The Attention Merchants by Tim Wu. It is a relatively long and detailed book about the history of advertising and other ways that people have tried to get into our heads and sell us on either commercial goods or ideas. It has a fairly extensive discussion of the development of advertising in newspapers, city posters, and radios, as well as further developments through TV and the Internet. Additionally, it goes through the cycles of development and backlash with respect to each medium of communication, noting how the backlashes are fairly similar to one another in many respects throughout history.

The book is quite interesting, and despite its longer length, it generally reads easily enough that this length is less noticeable. There are many examples given through each period of history and with respect to each medium of communication showing how advertising techniques further developed, and each of them is quite compelling on its own. I even learned a few interesting bits of trivia that I take for granted on a daily basis: "propaganda" was originally a straightforward (not derogatory) term for "propagation of [religious] faith", "broadcast" was originally an agricultural term (for spreading seeds through a field) that later got co-opted in advertising, and drive-in movies originated from the British government displaying war propaganda films from vans on large exterior walls in WWI. The only issue that I have is that the latter parts of the book become a little tiresome to read; part of that is because I have read from other places about the issues surrounding Internet tracking and advertising, while part of it is because the author could have better connected developments in Internet advertising to prior developments in newspapers/radio, so the repetition of key points without those deeper connections being made explicit (or only being made partway) felt a bit wearisome. Overall, though, I recommend this book for anyone who'd like to learn more about the history of advertising, how people have tried to fight back, and how the cycle continues.

Book Review: "More Than Just Race" by William Julius Wilson

The book that I've been able to read most recently has been More Than Just Race by William Julius Wilson. It is essentially a collection of 3 essays (each as a chapter) concerning various issues of the black experience (especially in cities) in the US, separately considering the conditions of black ghettos, the socioeconomic problems of poor black males, and the breakdown of poor black familial structures. These chapters are bookended by introductory and concluding chapters summarizing and further expounding on these issues. The main purpose of the book is to analyze, through various studies from the social sciences, the complementary roles of structure and culture in explaining why blacks in the US, especially in inner cities, are worse of by many metrics than their suburban counterparts and than people of other races/ethnicities in the US.

It is a relatively recent book (2009), but it isn't recent enough to have touched upon issues of police brutality and exploitation in urban black communities or issues of socioeconomic decay in poor white communities in cities as well as in rural areas (characterized by structural joblessness, opioid addiction, et cetera). The book itself is short, but the main three essays themselves are a bit dry. In particular, the essays are essentially separate from each other and can be read as such, but there aren't many attempts to form an overarching narrative (beyond the idea that structure and culture combine to explain the issues that many black Americans face), and the few attempts that do exist feel somewhat forced; perhaps the issue is that these issues are simply too nuanced to be described in a single broad brushstroke, but while that is clear from the details of the book, it would have been nice to see such a thesis made a little more explicit. Additionally, there are a few arguments that get rather muddled, and some ideas that aren't touched upon much after their introduction, perhaps because they don't fit the local narrative quite as well; I'll discuss these and other issues after the jump. Overall, while the discussion of structural issues seemed to be in line with a lot of what I've read in articles in newspapers and magazines in the last few years (probably because the author is an academic heavyweight in these areas anyway), the discussion of which cultural factors seem more (or less) plausible is relatively new to me, and their combination is much more nuanced than any of the broad stereotypes of individuals or institutions that I have seen previously; I rather appreciate this book for providing that perspective.

Book Review: "Gang Leader for a Day" by Sudhir Venkatesh

Happy new year 2017! My latest book review is of Gang Leader for a Day by Sudhir Venkatesh. The author is a sociologist who has meticulously documented his time in the 1980s as a PhD student in sociology, getting a deep, extended, first-hand look into the world of crack cocaine gangs in Chicago. He describes the progression of his relationship with the leader and close associates of a particular gang, the tenants and managers of the building that gang primarily operated in, the daily activities and quality of life of the gang members and building tenants, and even his own stint at leading the gang (in a very limited and supervised way) for a day. He further goes into the various moral quandaries that he finds himself in as he spends more time with this gang, with regard to when he should report something to the police, when he should step into a situation himself (thus inserting himself into a situation that he should be externally observing from an academic perspective), and whether his research will ultimately be essentially voyeurism writ large if he can't convince himself that publishing his findings will ever lead to measurable improvements in his subjects' lives, given the rampant corruption and cycles of poverty and crime prevalent then in Chicago.

Despite being nearly 300 pages, the book is extremely engaging, and the stories that he has documented have been masterfully crafted into a compelling narrative that flows very quickly and easily. I could really get a sense for the developments in his ability to conduct this research, his relationships with various tenants and gang members, and his comfort in such settings, going from the initial feeling of being very out of place, to the part in the middle where he still feels unsteady directly commandeering the gang (for a day, even in a limited and supervised capacity) despite his growing understanding of the gang's operations from the perspective of an outsider, to the part following that detailing his increasing comfort in seeking out broader perspectives from the community at large given his greater experience in conducting such research over time; I further liked how he ended the book by neatly wrapping up his narrative, mentioning his moves to Harvard University and then Columbia University, while still emphasizing that the story of the cycle of poverty and crime doesn't end so neatly for his research subjects, echoing what he says throughout the book. More than that, given that my upbringing as the son of immigrants from South Asia born and brought up in comfortable middle-class suburbs is quite similar to that of the author (except that he was born in India and brought with his family to this country at a very young age) and given that my family is extremely wary of me going into any situation that would remotely put me in danger (especially given my disability and skin color), this book really resonated with me. It felt thrilling for me to essentially vicariously experience this part of his life in such vivid and moving detail; I especially enjoyed reading about how a man who was fearlessly observing drive-by shootings, participating (however minimally) in gang retribution, and the like would still remain a principled vegetarian through it all, which I found deliciously ironic (and I realized that in a similar situation, I would actually probably do the same). One criticism of this book that I've seen online is that the author can be condescending and self-centered; given that this is a nonfiction book for general audiences, given that the goal is to weave his observations into a narrative, and given that he remarks throughout the book on the idea that there is no true neutrality and that he is inevitably going to be part of the story (on one side or another) that he is trying to document, I feel that anything else would have just been less honest in the end. I would highly recommend this book, and I do wonder how much relevance it could continue to have when considering the state of inner cities now, 30 years following this research, with the renewed emphasis on issues of police brutality, systemic racism from governmental institutions, and so on.
