There is a massive problem in the literature about bias in academia with ideologies of all sides pushing their agenda. This is connected to the amazing situation where nearly identical studies are getting nearly exactly the opposite results. See http://slatestarcodex.com/2015/04/15/trouble-walking-down-the-hallway/. The idea that everyone who is male is one side of this (complicated) ideological dispute and everyone on the other side is female is incredibly stupid.

In Canada we have an intermediate step between untowered uncontrolled airports and controlled airports with towers, Mandatory Frequency airports. They have a ground station with whom you must communicate for arrival and departure. They dispense information and coordinate activities, but do not give clearances. As pilot you make those decisions.

An example MF airport I've flown to is Kamloops, BC (CYKA). On initial contact the ground station told me the wind, altimeter setting and active runway, but also advised me of skydiving activity north of the airport. Since this might conflict on the usual left-hand circuit pattern, they suggested I fly a right hand circuit on approach. I did, and landed. This wasn't binding on me - the decision and responsibility were mine - but it was a good idea.

If they used reasonable numbers of significant figures I wouldn't mind so much. Since the altitude is specified to three significant figures (FL350), how about 10.7 km? The Air New Zealand system only did metric, BTW.

A later flight (Air Canada) had the bilingual in-flight thingy giving U.S.-bastardized units in English, and metric units (with, as usual, too many significant figures) in French.

I just got back from a vacation in Australia, and was annoyed that the in-flight display thingy insisted on displaying everything in "correct" units.

Showing the plane's altitude as 10,668 meters is all well and good, but is missing the point. Even a pilot from New Zealand (I was flying Air New Zealand) would have given the altitude as 35,000 feet. Flight level 350, strictly speaking, but few non-aviators would know what that meant.

Yes, I know they use metric altitudes and flight levels in Russia and China...

It's like how a real terrorist would not joke about a bomb at an airport. But someone who does is detained or arrested, and time is spent by TSA that could be better spent looking for real terrorists.

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.

If you feed it a -m command line switch, one of my applications informs you that Martian Mode is not yet implemented.

Lame, huh?

Thanks. A lot of these sound like "don't cares" in the instruction decoding logic. Reminds me of an undergrad course in logic design with lots of Karnaugh maps and stuff.

I wouldn't have minded seeing an example of one of those illegal opcodes and how what it did was useful.

Brooks called such things "curios". Side-effects of invalid operations that people had started to use, and that had to be considered part of the specification.

My policy (seconded by my boss) is that I do not document such things. If a hack is documented people start to use it, then we have to support and maintain it.

Top Gear was enormous fun at first, but it's gotten stale. It's lost its way. Maybe it is time for a re-think.

Like just about everybody, my picks for a new co-host include Sabine Schmitz and Vicki Butler-Henderson. But they have to look very carefully at the show and decide if its worth continuing first. I'm not convinced it is.

The original Top Gear production morphed in to Fifth Gear, which is definitely jazzed up fro the old Top Gear it started as.

I lost 160 pounds a few years ago, and I too did it the hard way. Count calories, exercise. If you're not eating that much you have to eat well, and I'm now so healthy it's slightly stupid. I like it.

I didn't gain it overnight, and I couldn't expect to lose it overnight. It took a year and a half. No major skin sagging issues except for a residual flab roll, eliminated with a tummy tuck.

People often ask me what my secret was, and I tell them it's motivation: you have to have a reason. For me it was wanting to learn to fly, but I couldn't get the seatbelt around me.

In the noughties my employers set out to develop similar technology. We had GPS-based units that would record where a vehicle was and could be programmed to tell on you if you drove too fast, stopped for too long, went to somewhere you weren't supposed to go, and so on. They communicated over a 2 way paging network.

The technology worked. I did the mobile device programming and put together a test unit that used differential GPS. Instead of telling you which street you were on, it could tell you which lane you were in. :-) The marketing, on the other hand, didn't work. :-(

If it's too clean, too clinical, people lose sight of the barbaric atrocity that execution is.

They also start to think that because it's clean, there's no reason to stop it. It should frighten (and gross out) any sane person.

The first year or two in any given country is generally pretty difficult to figure out how US taxes work with them. Once that's done it doesn't become an issue after that. As for US consular services, one gets all the advantages one gets from having another country as backup when something is going wrong. Unrest in a country you are staying in and people need to be evacuated? The US has done that many times for its citizens in the past. It has helped other countries evacuate their citizens as well, but they generally have given priority to US citizens. Have legal trouble in another country? Having access to people from the embassy of the country with the big military helps. US citizens are in many places treated better as a result.
