Comment: I lost weight too, but for some it's hard (Score 1) 491

by shoor (#49327849) Attached to: Hacking Weight Loss: What I Learned Losing 30 Pounds

I've gone through the drill of losing weight by dieting, then gradually putting it back on again a few times.

I'm in my late 60s now. In my early 60s I was overweight by about 20 pounds. In my last go at it, I lost the weight slowly over a period of years, and I've kept it off for a couple of years now, without ever 'suffering' (much). Mostly all I did was think before I ate something, asking myself do I really want this food? Since my metabolism has apparently slowed down, I can't go by old habits. I've learned not to eat meals at night, just something very light (some nuts, or a slice of toast with olive oil, something like that) at night if I'm really bothered by an empty stomach.

I don't know what's different this time that I'm keeping it off, except maybe practice makes perfect. Also, I'm old enough now that I get serious feedback (backpain, hard to sleep at night, sciatica) if I don't take care of myself. I see other people my age who are out of shape and I don't know how they can stand it. Maybe they are actually tougher than me intrinsically and that's why they can endure it. I don't consider it to be a question of will power or character on my part.

I'm not a sports fan myself, though I might be something of a meta sports fan in that I find myself intrigued by the phenomenon so to speak. I liked the movie Moneyball for instance.

So, I reckon some people probably like the fact that boxers are actually hurting each other (and some of them may be appalled by pure torture, and only like the act when it is between consenting adults), and others merely like the conflict, while still others genuinely appreciate the athleticism and skill of the 'sweet science'.

There's something primal about a fight, a no holds barred struggle to decide who is best, who would triumph in a desparate primitive situation. The problem is the damage of course. In a no holds barred with eye gouging and choke holds even the winner may come out with a permanent injury, so they have to have rules, and then it's a matter of who is best at working within the rules.

Some people like the fantasy version, professional wrestling with all its kayfabe. I'm sort of intrigued by the idea of robot fighting where it's OK if one contestant is totally destroyed, but from what I've seen, the technology is still too primitive for me to stay interested.

Sumo wrestling has a certain appeal because the individual bouts are very short, which makes it a little more viewer friendly than standard western style wrestling (legit wrestling that is), though the ceremony of entering the ring, scattering rice, glowering at each other while waiting for the ref to start the match, can take awhile. Also, as far as I know, serious injuries in Sumo are rare, but Sumo wrestlers tend to have short lives because of their diet. I sometimes think someone should design a form of combat where the matches tended to be very short, like Sumo, but designed to favor people who are all round athletic, but also with little chance of serious injury.

Comment: Is it measuring result of exercise or ...? (Score 1) 134

From what I read, they looked at people who took a stress test, and the ones who did well tended to live longer. What I'm wondering is, were the ones who did well people who were exercising diligently to get there?

There's a presumption that the people who didn't do well, if they worked out and lived healthier lives generally so that they improved their scores, would automatically be as healthy as the ones who were already doing well. But were the ones who did well from the getgo doing well because they had been exercising etc?

I'm not trying to say that exercise and eating right isn't a good idea. I'm just thinking that what is measured isn't only the result of a good lifestyle but also something more intrinsic, maybe genetic.

Comment: Re:real cost benefit new language (Score 1) 520

by shoor (#49068317) Attached to: Nim Programming Language Gaining Traction

The cost of a new language is that programmers have to take time to learn it and develop an infrastructure for it, things such as software libraries to do math, communications, user interfaces, etc. Not every programmer will learn every language, and, in particular, learn every language well, which may be a handicap for employers as they have a smaller pool to hire their programming teams from in their chosen language.

Companies have to spend time deciding which language to use, with a lot of people pitching this language over that one, and developing the languages will include a lot of duplication of effort.

The benefit is that new languages may improve productivity, with emphasis on 'may'. There's a lot of controversy about how good some languages are that have been widely deployed for a long time. Ideally, there will be a shakeout and the best languages will win, but I'm not convinced that's the way things happen. More likely it's whichever language gets the best salesmen out there selling it, and, to paraphrase Mae West, 'goodness has nothing (or little) to do with it.'

The earliest writing systems were complex and required years to learn. When easier to learn alphabets came along, the old scribal class would resist because it meant they couldn't command the high pay and respect they were used to. I suppose that might also exist to some extent with programmers and programming languages. It's hard to know who is being genuinely fair in judging languages.

The holy grail for employers and people who just want to use their computer to get work done, as opposed to people who make a living writing code (and I was one of those people who made a living writing code for over 20 years), is to have an artificial intelligence program where you can just explain what you want to it in human language and it will generate an optimal block of binary code to do it (after clearing up any ambiguities in your human language specification).

'having the code read like sentences' was one of the goals of COBOL wasn't it?

I studied COBOL in college, and the best Professor in the Department was a big fan, but I rememder it as being generally perceived as 'uncool'. (And I was the guy who, when given a choice of which language to write a project in, would write it in Univac 1100 assembler. This was before 'C' became widely known or implemented.)

Actually, I think you can have 'fluff' in assembler, though when writing assembler you're usually very focussed on some very specific thing that needs to be done, and sometimes every CPU cycle counts, so in practice, yes, you'll see less fluff.

I have just enough experience with Perl that I think I know what you're talking about with 'too-clever Perl'. There must be some great examples of 'too-clever APL' out there unless the mag tapes and IBM 2311s they were saved on have all Gone South by now.

There are options to one's lifestyle that matter vis a vis cost of living. If you live frugally in a high cost of living area, you may still be spending more than if you live frugally in a low cost of living area, but you can probably save/invest more money from that high salary, so it may pay off as part of a long term plan to build up capital.

I also realize that inflation can wipe out savings. Any long term plan is something of a gamble. My point is, that one shouldn't be too simplistic about weighing the alternatives.

I see most replies are critical that you didn't read the original article. (Maybe they don't get the 'lazy evaluation' part if they've never dabbled in functional programming.) Maybe they don't know about the actually rather serious philosophical speculations that our universe may be a simulation. Anyway, I for one thought it was clever.

A thousand years from now is Homo Sap supposed to still be the pinnacle? A million years from now? Are we just supposed to evolve 'naturally' the way we did away from homo erectus? (And do you suppose that went easy on Homo E?)

I realize that since we H. Saps are still sort of in charge we may try for a gentler transition that has probably happened in the past, but we do want a transition don't we? I mean, we don't want everything to be just us with our limitations a zillion years from now do we?

I think it has more to do with being light weight since birds fly. After all, not all birds dig for grubs. Of course, not all birds fly anymore, but maybe the common ancestors did.

Another thing, birds evolved from reptiles. I watched the science documentary series 'Your Inner ...' (Inner Fish, Inner Reptile, etc). They mentioned that reptiles can replace their teeth but the teeth are undifferentiated, whereas mammals, who only get two sets, have them custom designed with a tight fit so some are good for tearing flesh, some for grinding, etc. Presumably the teeth the birds lost would have been less efficient reptile teeth.

Unless we wipe ourselves out or reduce ourselves to a stone age existence, AI will happen. Whether it will replace ordinary human beings in a gradual, gentle way (maybe preserving us awhile the way we preserve threatened species now) or whether it will be something more unpleasant, that's what is hard to predict. There's bound to be surprises however it goes.

But suppose somehow the folks opposed to AI could stop it. Then what? 1000 years from now, would ordinary human beings still be doing their thing? Would we have managed to create a utopia or would there still be human vs human strife? And a million years from now, would they still prevent anything 'superior' from replacing ordinary humanity? Is that a future to be yearned for?

Perhaps it will be a kind of middle way of transhumans with artificially enhanced intelligence, with the artificial part of the transhumans becoming a larger and larger part of the total being until the purely human part is just a tiny vestigial thing.

No problem is so large it can't be fit in somewhere.
