  1. Ops team "converted" secure emails to insecure on State Dept. Releases 5,500 Hillary Clinton Emails, 275 Retroactively Classified (nbcnews.com) · · Score: 2

    The real problem, which gets far too little discussion, is that Hillary Clinton seems to have set up a system where state department employees (from the "ops" team) would read classified emails on the secure email system, and then type up a summary and send the summary to her personal (non-secure) email system.

    In the first e-mail, Clinton curtly instructs Sullivan, "It's a public statement. Just email it." Minutes later, Sullivan responds, "Trust me, I share your exasperation. But until ops converts it to the unclassified email system, there is no physical way for me to email it. I can't even access it."

    http://www.nationalreview.com/classified-rules-hillarys-disregard-for-them

    Naturally, when ops "converted" the emails, they didn't copy over any classification markings, allowing Hillary Clinton to truthfully say she never received any emails marked as classified.

    It is partisan spin to use the word "retroactively" to describe these emails being newly marked with classification markings. If the information in the emails was classified, the emails were classified all along; it doesn't matter whether the emails were marked as classified or not... and Hillary Clinton, who is not dumb and is a lawyer, knows this.

    This process of "converting" emails from secure to insecure is go-to-prison stuff. It's truly amazing that Hillary Clinton thought she could get away with doing this.

    Unless the information in this article is fabricated or otherwise untrue, she is going to be in very big trouble:

    That Hillary and her staff at Foggy Bottom were wittingly involved in a scheme to place classified information into ostensibly unclassified emails to reside on Clinton's personal, private server is the belief of every investigator and counterintelligence official I've spoken with recently, and all were at pains to maintain that this misconduct was felonious.

    "The FBI will get someone to talk, we always do."

    "This was about a lot more than just some classified emails," a senior Capitol Hill staffer told me, "and we'll get to the bottom of it. But we're happy to let the FBI do the heavy lifting for right now."

    So, the only way to handle the issue without having godlike powers is to take all of them.

    Can't be done. Impossible. You are dreaming.

    As long as we are going to wish for the impossible, I wish that all the people who are willing to hurt others would simply be kind people who don't want to hurt others.

    If you want me to believe that you can keep guns out of the hands of violent criminals, first show me a place where junkies are unable to buy crack cocaine. Crack cocaine is not legal for anyone, anywhere... we have Draconian laws about it and those laws are enforced.

    And yet the junkies are able to get their fix, week after week. (Most violent criminals who have a gun don't get a new one very often... certainly not every week.)

    Thus, our choices as a society: either only criminals will have firearms, or everyone will have firearms. And Gary Kleck's research shows that legal firearms in the hands of ordinary citizens deters a substantial amount of violent crime each year.

    I read an essay that I found very moving. It was written by a guy who worked for civil rights for black people in the deep South in the 1950's. He said that he will forever be opposed to any attempt to make it illegal for law-abiding citizens to have guns, or to give the police department authority to decide who may have guns and who may not. Black folks being legally armed prevented an uncountable but nonzero number of lynchings, and he said in some cases the local recruiting station for the KKK was the local police department.

    TL;DR If you take away the legal defensive uses of firearms you will increase the amount of violent crime (by preventing some violent crimes from being deterred) and you will not prevent violent crime because criminals will still be armed.

    Sure, the link between handguns and violence is obvious.

    Handguns can be used to commit violent crimes, but they do not cause crimes. Violent criminals regard a firearm as a necessary tool of their trade, and they will have one.

    If you somehow got the magical ability to get rid of all the firearms, people would still kill each other with knives, blunt instruments, and hands and feet. More people are killed by hands and feet each year in the USA than are killed by any weapon in the UK each year.

    In the past two decades, the number of firearms in the USA has dramatically increased while at the same time the number of violent crimes has decreased. If guns caused crime, this would not be the case.

    So, in the end, you and I want the same thing: as few violent crimes as possible, ideally none. We disagree on how best to achieve that.

    Hmm, then I apologize for choosing a poor link to use. What I got out of that is "for two decades I have been hearing the same criticisms and none of them are invalid" and I guess what you got from it is "narcissistic".

    Better then would be to read his actual book. http://www.amazon.com/Point-Blank-Guns-Violence-America/dp/020230762X The American Society of Criminology awarded Professor Kleck the Hindelang award for this book.

    And the other URLs you gave are obviously from pro-gun sites so I didn't go there.

    Perhaps you didn't realize it, but the Kellerman study was published in an obviously anti-gun publication.

    Also, Arthur Kellerman has been a member of at least one anti-gun organization. (The latter link is to an obviously pro-gun web site, but it reproduces a letter to the editor published in a medical journal by a doctor. The doctor is an obviously pro-gun doctor, but he is providing evidence that Kellerman is an obviously anti-gun doctor, and I don't know how I would go about finding a completely unbiased source you would accept who has taken the trouble to research Kellerman and report on his membership in anti-gun organizations.)

    Finally, here is a book I recommend: it thoroughly covers the statistics around violence and gun ownership. It concludes that cultural factors are much more important in violence than the number of available firearms. The Samurai, the Mountie, and the Cowboy

    It's scientists trying to deal with an illness and its causes, rather than folks who started with a point and then used Polya's tactics to justify it.

    Oh, really? I have provided multiple links to you showing that Kellerman's study was structurally unsound. We cannot put error bars on its conclusions, it had a small sample size, and it only counted defensive uses of a firearm if they resulted in a dead body (which drastically under-counts defensive uses). Even if you believe that it was intended as an unbiased study, its flaws render its results useless.

    Also, its predictions have not been borne out in the following two decades. I have provided evidence for you that the number of guns in the USA rose dramatically since the publication of the Kellerman study, while shootings of all kinds (accidental and intentional) declined dramatically. I am not going to claim that the drastic increase in guns caused the decline in shootings; but pretty clearly if a gun is 43 times more likely to hurt you than to be a benefit, the drastic increase in guns should have been correlated with a drastic increase in harm.

    Here's a reference that presents these facts. This Economist article has graphs that show firearms deaths declining drastically since the early 1990s at the same time that the number of firearms in the USA dramatically increased. (By the way, the article ends with a sentence saying that the link between guns and violence "is obvious" despite the clear evidence to the contrary presented in the article. I doubt they cherry-picked any data to try to make firearms look less dangerous.)

    Finally, if it is unbiased research you want, I recommend you read the Wright/Rossi/Daly book. The Carter administration funded research into gun control, and Wright and Rossi engaged in the research expecting to prove that gun control prevents violence. Their research showed the opposite, and changed their minds on the subject.

    The Kellerman study was badly and tendentiously designed.

    The worst flaw: that study only counted uses of a firearm that resulted in a dead body. If some guy kicked in the front door of a home, and the woman inside pointed a gun at him and he left, then Kellerman's study would not count that as a "use" of a firearm. Because most defensive uses of a firearm do not result in the weapon being fired, let alone anyone dying, this structurally stacked the deck against defensive gun uses.

    That study also lumps in suicides with homicides. I have not seen any honest study that shows that a gun in the home causes an increase in the suicide rate.

    The study started with people killed by firearms, which meant there was a 100% chance of a firearm being present, but then guessed whether there was a firearm in the home of a "matching" person. We have no way of knowing how many of the "guesses" were correct, and each case where they guessed wrong would lower their result. We literally cannot put error bars on the result.

    Kellerman's own data showed much higher correlations: having an adult in the home who has a previous felony conviction for a violent crime is a much better predictor of the chance of violence.

    There are plenty of articles on the flaws in the Kellerman study.

    Since 1992, the number of unintentional shootings has declined by 57% in the USA:

    http://sssfonline.org/nssf-report-unintentional-firearms-fatalities-historic-low/

    Since the early 90's, the number of intentional shootings has also fallen roughly in half. It fell more quickly than the unintentional numbers but then plateaued. Note that this statistic excludes suicides... properly, IMHO, as I don't believe that guns cause suicide.

    http://www.pewresearch.org/fact-tank/2015/10/21/gun-homicides-steady-after-decline-in-90s-suicide-rate-edges-up/

    And both of these declines are despite the fact that there are more firearms available than ever before. This article has a chart that starts in 1996; it shows that in 1996 there were less than 250 million firearms in the USA, and currently there are over 350 million firearms in the USA. That's over a 40% increase in the number of firearms.

    https://www.washingtonpost.com/news/wonk/wp/2015/10/05/guns-in-the-united-states-one-for-every-man-woman-and-child-and-then-some/

    Therefore, the increase in guns must prove that the guns caused the reduction in violence, right? Well, no. Correlation doesn't prove causation.

    However, these numbers do show that guns don't magically cause violence. If guns caused violence, then the massive increase in the number of guns should be correlated with an increase of violence rather than a decline.

    So: if you "live your life by real numbers", and you want to argue in favor of taking firearms away from the law-abiding, then please provide some statistics that support your plan.

    Device Management Allows KDE to have access to your mouse and keyboard without root access and without random applications being able to sniff your keystrokes.

    Each tab is a different computer. Tab 1 is generally the local computer upon which I am working; then tabs 2 through whatever are the various remote machines. I ssh to the remote machine, then run tmux and open as many windows as I need.

    tmux is essential so that I can pick up where I left off if anything interrupts my work... with SSH, if your Internet connection glitches, you lose your connection; with tmux you can re-attach to your previous session and continue your work right where you left off.

    I have met someone who runs doubly-nested tmux sessions. He binds both Ctrl+A and Ctrl+B as prefixes, and he uses one of them to switch "outer" sessions (which are one per machine) and the other to switch nested terminal windows (multiple windows for working within a machine). I like having the separation of using Alt+1 through Alt+0 to switch machines and then Ctrl+A,1 through Ctrl+A,0 to switch windows on a particular machine. (Besides, I'm a vi user and I actually use Ctrl+B when editing.)

There are "hotel room" units that residents can book for their guests. There are a few shared offices, used for people who work at home and sometimes need to meet with clients or consultants. There are storage spaces available for monthly rental, so people who have too much stuff for their small apartments can just walk down the hall to access the stored stuff. I think there is some kind of small clothes washer/dryer in the apartments but I wouldn't be surprised if there were a couple of large ones somewhere for shared use.

If you want a huge TV screen once a week to watch a football game, you could use the theatre room and probably end up meeting everyone else in the complex who likes football. If you sometimes like to throw a party with lots of guests, again the theatre room with its attached kitchen is the place to do it. Your apartment doesn't need to be big enough to have guests overnight because you can book the "hotel rooms" ahead of time.

    You need to remember that at the time Heinlein wrote that, computers did exist, but not general-purpose stored-program computers. Back then, computers were special-built things that had one purpose, like fire-control computers in the Navy; you couldn't make a fire-control computer do something else by swapping out a program.

    All that said, you aren't wrong. Starman Jones is actually a bit clumsy; the computer works the way it's shown in the book because it has to work that way for the story to play out as Heinlein wanted it to. The idea of humans using pencil and paper to quickly compute the numbers to feed into the computer is silly; at a minimum there should have been another special-purpose computer device there to help them with the figuring.

    P.S. I also enjoyed Beyond This Horizon where a computer expert in the far future wishes he could build a computer with 4-dimensional cams, since the three-dimensional ones weren't complex enough for the calculations he wanted to perform; and in Methuselah's Children (set in the 22nd Century) the protagonists steal a spaceship that had "one of the new computers with no moving parts".

    What I find interesting is that it took a tremendously more advanced technology to render slide rules obsolete.

    To make a slide rule, you need to figure out logarithms, then make exact marks on wood or something.

    To make a modern calculator, you need to invent the microchip! You also need to invent a suitable display technology: light-emitting diodes or liquid crystal displays. We literally put a man on the moon before anyone was able to make a pocket calculator.

    I love reading old science fiction stories set in the far future, where in the year 3423 or whatever people are still using slide rules. I imagine in the year 3423 people will still be using chairs, and probably spoons won't be too different... and back when those old stories were being written, slide rules seemed like that kind of basic item that wouldn't be going away.

    P.S. Before the "pocket" calculator was invented, there were electronic desk calculators using Nixie tubes! Watch this video and think of how much labor it would be to assemble one of these. The soldering work alone guarantees that a typical college student could never afford one of these, but I'm sure NASA had calculators like this for engineers to use.

  21. It seems to me like the best possible way to clean a space station would be to use a steam vapor cleaner. The environmental systems have to already be designed to deal with water vapor in the air, and the steam vapor cleaner uses no chemicals other than water, which would be recycled. A good steam vapor cleaner doesn't get things very wet... the steam is very hot.

    I wonder whether they can afford the power to make steam... I don't know how much spare power they have from the solar power system. Maybe future space station designs could have a built-in steam cleaning system that uses solar power to directly heat the steam.

    I bought a steam vapor cleaner, coincidentally because I wanted to use it to kill some mold. It worked perfectly for that purpose. I got a Vapamore MR-100 and I would buy it again.

    I'm sticking with Apple devices from now on.

    If you really want total control over your own devices, you can't beat Android. The trick is to choose a cell phone carrier that lets you own your own device.

    I was a customer of Verizon for years and years, and I was happy with the quality of the cell phone service. I bought a Galaxy Nexus, happy that I would get updates (it's a Nexus device, right?).

    Then I didn't get updates. Google released the updates, but Verizon didn't let them through. My Galaxy Nexus became so slow it was almost unusable, and I firmly believe that the Android 4.3 update (which added "TRIM" support) would have fixed my speed problems. All Galaxy Nexus users got the 4.3 update... except Verizon customers.

    So I switched carriers. We are on T-mobile now and we have Nexus 5 phones. Overall, we are happy with T-mobile.

    The Galaxy Nexus is past its end-of-life and Google isn't supporting it... but if I were to root it, I could put Cyanogenmod on it and get KitKat and the latest security patches. With the Nexus 5, I wouldn't even need to root it to use community-supported firmware builds; the devices aren't locked.

    If you want total control of your own devices, Android devices plus a carrier that lets you buy your own devices is the way to go.

    I don't have a clear picture of what your organization will be doing, but your comment about "managing that data (=measurements + reports)" made me wonder if you will want to use the IPython notebook.

    http://ipython.org/notebook.html

    When people work to analyze measurements (make plots, etc. and make decisions) and then write new code, if they do so step by step in an IPython Notebook, and then other scientists can peer-review the notebooks, this might be even more useful to you than version control. It would give you a history of how the analysis was done and why the reports were made the way they were.

    In my job, I do some analysis and work in databases, and I seriously want to start using IPython Notebook as my SQL client, and save my notebooks for later review. It would document the queries I ran and the results I got, so later I could find the queries again to re-run them, and see how they worked out before re-running them.

    You know, it occurs to me that you probably quit reading the novel at the worst possible place. You are so qualified to spot mistakes with chemistry and indoor gardening that you were repeatedly outraged and stopped a quarter of the way through. You missed on the later parts where the problems being solved had nothing to do with chemistry and indoor gardening.

    I read an article where a couple of orbital dynamics guys said that Any Weir got the orbital dynamics stuff basically right; I've read multiple comments that said that the NASA politics stuff was believable; and in one of my favorite parts, Watney was stuck with a spacesuit whose helmet faceplate's glass had broken and he had to solve the problem of getting back to safety with a rather leaky spacesuit. There are other parts I don't want to mention because they are too spoilery.

    You are probably too soured on the book to enjoy it, but if you ever try finishing it, I think you will find that the rest of the book offends you less than the first quarter of it did.

    Seriously, how can you read this tripe without wanting to hit your head against a wall? How can you call a novel that has this sort of nonsense and does almost every single chemistry equation wrong "hard science fiction"? Does anything that spouts pseudoscientific BS qualify as "hard science fiction" these days?

    IMHO you are being too hard on the book. In the book, the things Watney does are plausible solutions to problems that make sense to me.

    Andy Weir said he didn't want Watney being "hit by lightning" over and over. The initial chain of events that leads to Watney being stranded is implausible (and Andy Weir is the first to admit that the physics is wrong there, because the atmosphere of Mars is so thin). But once Watney is stranded, the rest of it makes sense to me.

    This isn't like a story where someone needs to "restart the sun" by flying a ship made of "Unobtanium" into the sun and lighting off nuclear bombs. If you fix the science mistakes in a story like that, there is no story left; it's just fundamentally wrong.

    In an interview, Andy Weir mentioned getting feedback from some chemist, and he said something like "I loved that, because chemistry is what I'm worst at". It sounds like you are so expert at the chemistry stuff that every mistake was a torment for you, and I think I get it... I can picture how annoyed I would be if the book was about software development, and lots of little stuff was constantly wrong.

    One of his mistakes: someone actually calculated how much the Hab would heat up from burning up the rocket fuel to make water, and concluded that if Watney burned the fuel as fast as described, the Hab would heat up to 400 degrees C. But that mistake doesn't ruin the book for me, because we can assume that he just didn't burn the fuel as fast, or he arranged some sort of heatsink or something to get rid of the heat. Fundamentally, you can make water by burning hydrazine in the presence of oxygen, so it works for me.

    I also liked the way he portrayed NASA. On the one hand, everything NASA does is expensive and takes forever, but on the other hand, his equipment works and he trusts it; and there was one launch that failed, and Weir listed two places where NASA procedures would have prevented the failure if there had been more time. (Someone would have studied the effects of a "shimmy" on protein cubes, and also someone would have found a minor defect in a bolt and replaced it with a perfect one; either of these would have prevented the failure.)

    A novel that I hated, that I just couldn't get through, is The Windup Girl. I bought it figuring "anything that wins both the Hugo and the Nebula must be worth reading" but I hated it. I couldn't swallow the science upon which the whole plot rests. It's the future, and the worst predictions of catastrophic anthropogenic global warming came to pass: the sea levels have risen, temperatures are high, lots of people died off. As a result, fossil fuels are no longer used by anyone, and the world is in a horrible depression. So, you might think that nuclear power, solar power, and Internet telecommuting would be a big deal? Nope, cities are lighted with methane gas lamps, and the methane is made from animal feces, and moving things are powered by kinetic energy stored in "kink-springs" and the springs are wound by elephant-sized bioengineered animals. No buildings seem to have solar panels on them, and at one point the protagonist uses a computer powered by a treadle! The Internet barely seems important, which is hard to believe given that the Internet is already hugely important... but in this future catastrophe world it now takes months for a business executive to travel from America to Thailand (he has to travel by wind-powered ship), yet they still send the executive instead of using teleconferencing.

    I hated The Windup Girl as much as you seem to have hated The Martian
