My source of disgust is directed towards the tech media punditry. Because what they're demonstrating is that they don't have a clue what reddit management did wrong. They're just either covering up management's (Pao's) fuckup in the name of professional "sisterhood", or just care about how another startup is going to have lost investor money.

I dunno, I thought my write up on Ars was pretty good.

Comment p-value research is misleading almost always (Score 5, Interesting) 208 208

I studied and tutored experimental design and this use of inferential statistics. I even came up with a formula for 1/5 the calculator keystrokes when learning to calculate the p-value manually. Take the standard deviation and mean for each group, then calculate the standard deviation of these means (how different the groups are) divided by the mean of these standard deviations (how wide the groups of data are) and multiply by the square root of n (sample size for each group). But that's off the point. We had 5 papers in our class for psychology majors (I almost graduated in that instead of engineering) that discussed why controlled experiments (using the p-value) should not be published. In each case my knee-jerk reaction was that they didn't like math or didn't understand math and just wanted to 'suppose' answers. But each article attacked the math abuse, by proficient academics at universities who did this sort of research. I came around too. The math is established for random environments but the scientists control every bit of the environment, not to get better results but to detect thing so tiny that they really don't matter. The math lets them misuse the word 'significant' as though there is a strong connection between cause and effect. Yet every environmental restriction (same living arrangements, same diets, same genetic strain of rats, etc) invalidates the result. It's called intrinsic validity (finding it in the experiment) vs. extrinsic validity (applying in real life). You can also find things that are weaker (by the square root of n) by using larger groups. A study can be set up in a way so as to likely find 'something' tiny and get the research prestige, but another study can be set up with different controls that turn out an opposite result. And none apply to real life like reading the results of an entire population living normal lives. You have to study and think quite a while, as I did (even walking the streets around Berkeley to find books on the subject up to 40 years prior) to see that the words "99 percentage significance level" means not a strong effect but more likely one that is so tiny, maybe a part in a million, that you'd never see it in real life.

Comment timing - which year (Score 2) 72 72

I travel a ton and stay in dozens of different hotels every year. Domestically, and in maybe 50% of the foreign cases, the high priced hotels had worse and slower internet up until a couple of years ago. For the last 2 years they have gotten better, on the average. Oh, I was in a 5-star Vegas resort last night that had horrible bandwidth. In the past, my joke was accurate that the difference between a Four Seasons (just an example) and a Super 8 is that at the Super 8 the internet worked and was free. The most important thing to me in a hotel is computer use. The fancy suites in major hotels are often set up for entertaining friends and DON'T even have a computer desk. I ask my wife to book me into Super 8's whenever possible.

End goal: change the constitution. We need a start. It's easy to see how hard this will be and to give up early, but some of us feel the imperative to fight for it. We can change things. The vast will of the masses (corporation political donations are not equivalent to the free speech we enjoy as individuals) needs to be strategically gathered. Critical mass could take decades, as with things like gay marriage.

Yes, I contacted JSC PAO and they unequivocally said that there are no "virus epidemics" on the ISS. There is no current outbreak of anything, stuxnet or otherwise. Kaspersky's comments weren't about an ongoing event—rather, they are off-the-cuff unsourced remarks that could refer to any number of past incidents.

Comment Re:Summer (Score 1) 346 346

Winter. It's the best three weeks in Texas, and the only time you're able to go outside without becoming sticky with sweat after 15 seconds at any time of the day or night. Plus, you get so sleep with an actual blanket, instead of the thinnest sheet you can find. It's great to actually be able to wear normal clothes outdoors—layers! Suits! Coats!

Summer is my least favorite. Sure, you can go to the beach, but it lasts eight months, from April through November, and every second of it is an experience in humid misery. You spend your time dashing from one air conditioned space to the next, dreading your $400 monthly electricity bill (because of your home's central air), and dreaming of what it feels like to be cold.

If I could move, I would. Unfortunately—perhaps BECAUSE it's so miserable down here—home prices are ludicrously reasonable, so I stay.

That's insane. If someone steals my credit card number, there's fast and quick legal redress. The most inconvenient part is waiting for the credit card company to overnight me a new card.

Paypal, on the other hand, can lift actual money right out of the checking account they insist on linking to my account and actually defraud me. There is literally no instance where simply using a credit card number is less safe than dealing with paypal.

Probably too late to pick up any moderation points, but no. The CAD files are considered export-controlled technology and are not publicly available. I asked this specifically when I was talking with the engineers involved in the effort. It's also why the article I wrote (linked up-thread) lacks images of the disassembled F-1 engine and its components. I desperately wanted to photograph the lab and its awesome assortment of rocket parts, but NASA and the US government did not allow pictures of export-controlled technology.
