  1. a good thing on National Security Jobs To Rival Silicon Valley Over the Next 10 Years? · · Score: 1

    I don't want to be at a place where the Indians eat lunch together, the Chinese eat lunch together, and the few remaining people feel like outsiders in their own country.

    I also like being able to reliably tell when somebody is pleased, pissed off, joking, or whatever. I can't do that very well across cultures.

  2. Re:don't need sudo for that on Common Traits of the Veteran Unix Admin · · Score: 1

    Nope, I mentioned "bare non-X11 Linux console".

    Once you're tainted by either su or sudo, it isn't much of a big deal to add the whole GUI. You've already lost the Trusted Path component of security.

  3. how to do 'sudo cd' on Common Traits of the Veteran Unix Admin · · Score: 1

    sudo ed /dev/mem

    (follow with a bit of editing to change the inode number of the working directory in your process structure)

    You can use "sudo vi /dev/mem" or even "sudo gdb /dev/mem" if you're a wimp.

  4. excellent point, but not enough on Common Traits of the Veteran Unix Admin · · Score: 1

    Malicious code could mess with your shell so that even "/bin/su -" doesn't do the right thing.

    The proper solution is direct login as the desired user. If using SE Linux, also specify the correct role and MLS info at login.

    Use the bare Linux console. If you absolutely must be remote, use a trusted client with pre-shared ssh keys or a hard-wired serial line.

  5. don't need sudo for that on Common Traits of the Veteran Unix Admin · · Score: 1

    For example, I use virtual desktops. The first one is reserved for stuff involving root. On that desktop I open one xterm for root commands, and several others for related stuff such as checking man pages. I immediately make the non-root windows big, reducing the temptation to read man pages as root. For the root xterm, I do "exec su -" and keep it small.

    I don't use any of those windows for random user stuff. (not even the non-root windows) I switch to a different desktop when I am not doing root-related actions.

    If I were more serious about safety, I'd eliminate both sudo and su. It is unsafe to elevate privilege. The safe choice is a direct login, preferably on the bare non-X11 Linux console. (do Alt-Ctrl-F2 if you're unfamiliar with this) Hit the SAK sequence to be extra safe. An ssh login directly as root from a trusted client is a tolerable alternative, at least if you use pre-shared key information.

    Misogyny: Women are only good for sex, having babies, cooking, and cleaning.

    Respectful: Women are most satisfied as stay-at-home moms because this is their natural instinct. No job is more important than the raising of children. Staying at home is a privilege. Cooking and cleaning, although expected of one who doesn't work outside the home, must always be appreciated.

    It works for me. She's a decently bright woman who would have finished a nerd degree if I didn't keep her pregnant. I'm 2/3 the way to my dozen kids.

    Outbreeding is possible because it is not only religion that causes kids. There is also the desire for kids, which is likely to be at least partly inheritable.

  9. close, but not quite on Sputnik Moment Or No, Science Fairs Are Lagging · · Score: 1

    Work that actually teaches is only useful for those who actually care to learn.

    Essentially all students are motivated by social power, the vast majority of students are motivated by money (cold hard cash this week, not some savings bond), and essentially all students become motivated if the parent becomes motivated. As for the parent, again it is money.

  12. it has to be believable on Sputnik Moment Or No, Science Fairs Are Lagging · · Score: 1

    You're trying to get smart people to be teachers. They are smart enough to know that a nice salary can disappear at a political whim. A temporary bonus won't do, and neither will a salary that smells like a temporary bonus. Things become almost believable if the state constitution says that math/science teacher salaries will average 2x the other teacher salaries.

    There is also the shit work environment. Teachers need combat pay. At my workplace, nobody assaults me. So really, 2x probably isn't enough. 3x is more like it.

  13. oh yes you can on Sputnik Moment Or No, Science Fairs Are Lagging · · Score: 1

    Simply reward/punish the parents.

    The easy way is money based on class rank. Even if mom just wants to buy crack, she will care.

  14. motivation on Sputnik Moment Or No, Science Fairs Are Lagging · · Score: 1

    Never make the assumption that what motivates you motivates others. The students I help may still fail their class and fail the tests. This means they will have to retake the class. And continue to take math until they pass the tests. And they don't like math. Yet this doesn't motivate them to learn math.

    This is indeed the heart of the problem. We make no serious effort to motivate students. We simply assume that they are motivated.

    OK, there are many ways to motivate students. Reluctantly I will disregard the "sheer terror" method, because it interferes with concentration. :-) We're left with social status and parental pressure.

    Parental pressure means you focus on the family. Take a student's class rank, as a percentile, and pay that many dollars to the family every week. I'm sure there are other ways. When educational success affects the parents (near-term, not many years away) you get the parents to care. Even if dad is just looking for drug money, he's going to care.

    Social status works too, especially for the older kids. It's best to grant power. For example, you could require that the average class rank of a sports team (weighted by in-game time) always be above the average of the people who wanted to be on the team. You could require each prom couple has an average that exceeds that of the whole student body, ensuring that the top students can pair with anybody while the bottom students can only pair with top students. (nerds get the hotties) You could subject low-performing students to daily drug tests. You could allow top-performing students to skip class, sit in the wrong class, wander the halls, order pizza delivery, and leave early. Low-performing students could face a dress code involving grey Mao suits, while high-performing students can show up in thongs. You could adjust state law to let the top students drive cars at age 14 while making the bottom students wait until age 25. You could adjust state law to let top students have beer during lunch.

    Right now, there is nothing to make parents care. Right now, students only care about winning the social war. Take advantage of what really motivates people, and education will happen.

  15. Re:Why not just install some phones? on Prison Cell Phone Smuggling Out of Control · · Score: 1

    OK, we do it at their home and we mandate that the whole neighborhood be there to watch. The deterrent is more "real" if it's right there, pronto, gruesome, and humiliating. Think "naked and covered in stinging insects". The criminal needs to dies screaming in agony while all his buddies watch. Maybe add some sexual or religious humiliation too, like getting butt-raped by a pig or dog.

  16. rate of re-offence on Prison Cell Phone Smuggling Out of Control · · Score: 1

    Look, this isn't a problem in Russia. There is a very low recidivism rate because people actually fear going back to prison. Our prisons are just comfy free room and board by comparison.

    Russian prison guards beat the prisoners, often for no serious reason. For example, a new guard gets a job and all the prisoners get beaten as a way of introducing the new guard. Russian prisons are thousands of miles from home out in Siberia, despite legislation to the contrary. Russian guards assign some prisoners the job of keeping order in exchange for better treatment. If one of these prisoners gets killed, his killer often replaces him. Prison is normally not heated enough. The food is truly crap.

    Our prison just isn't prison. It's almost house arrest, but in a hotel with TV and video games. We even offer fun education. Going back to prison just isn't terrifying.

    It could be an alternative to this sort of thing:

    It goes from one factory (or warehouse) to another. Both have the same owner and are in the same city.

    This is the sort of solution you might choose if you are unable to expand your existing property. You buy another property near by and then connect them.

    The big trouble is getting the rights to install such an ugly thing. You'd have to lobby the government to make a special allowance. Probably you'd go on about how you're bringing jobs to help the local economy. Maybe the government would even help you, probably by grabbing chunks of land for the support towers.

    Some people produce lots of kids. They will pass on the traits, both physical and mental, which cause this. Soon enough, everybody in the population will refuse to use birth control (or just fail at it, in the idiocracy scenario) and our population growth will go exponential until we start dying from overpopulation.

    The natural state of all living creatures is to live in squalor. You are very lucky to live in the current anomaly.

  22. "wants to" is genetic on Model Says Religiosity Gene Will Dominate Society · · Score: 1

    So, why would a person want to pass on his DNA?

    This is a brain feature. We've already discovered numerous cases where such features are inheritable. Most have been the subject of Slashdot articles.

    For example: faithfullness, IQ, violence...

    This isn't any different. Any behavioral trait that increases descendents in the Nth generation will become more common. In modern human society, most strongly selected traits will be mental. A few will be disease-related or diet-related, so you can live on a McDonald's diet while screwing all day long. Mostly it's the brain that matters, because brain features are most capable of defeating birth control.

    Homosexuality becomes more and more likely as a mother produces boys all in a row. (accounting for home environment via adoption studies)

  24. no, not parenting on Model Says Religiosity Gene Will Dominate Society · · Score: 3, Interesting

    Parenting greatly influences the choice of religion, but not the strength of belief. Studies of adopted children show that there is a very strong tendency to become more like the biological parents during early adulthood. A child of atheists raised in a young-earth household is likely to become less of a believer once out of that environment, while a child of young-earthers raised by atheists is likely to convert to some religion.

  25. does not need 100,000 years on The Rise and Rise of the Cognitive Elite · · Score: 1

    If we were looking for traits that are not already in the population (people with wings) then sure, evolution would be slow.

    If the selection pressure were mild (avoidance of a 1-in-50000 cancer) then sure, evolution would be slow.

    Evolution is damn fast when the selection pressure is high and the desired trait is already in the population. In the extreme, it just takes a generation. Want immunity to HIV? Simply inject everybody with it, let 99% of the population die, and suddenly humans all have natural immunity.

    Idiocracy has some fairly severe selection pressure going for it. The effects will be seen within a few generations. Some of us may even live long enough to see it, though most will place the blame on something else. Arguably it is already measurable; the Flynn Effect has died out and possibly reversed.
