QSIITurbo··on Exercise 'keeps the mind sharp' in over-50s, study finds
If people used their time to study and learn new things instead of fretting about their exercise, they'd be able to interpret the results of studies like these.
QSIITurbo··on The History of Computer RPGs
Great stuff. You might want to consider adding Borderlands 2 into your list. It's basically Diablo 3 from the scifi first person (shooter) view. In addition to being refreshingly humorous, it has the one and only bad guy I've ever found realistic among the zillions of CRPG's I've played. There are other games in the series (1 and TPS) but they're not as good.
QSIITurbo··on Why Did My Patient Leave Me?
No it wasn't a situation like that. It was just that some papers needed to be delivered to someone (don't want to go into details). There were two relevant people: the doctor and the destination. There was no need for the nurse other than some agreement between either the company or the union.
QSIITurbo··on Why Did My Patient Leave Me?
Another alternative that I've run into. Visiting a doctor friend of mine. She needed to deliver some papers to another room and summoned the nurse for that. I joked that why you can't do that yourself (omg) and she replied that the nurses start to complain if you do stuff that's earmarked to them. It might be that it's because they're in a union or it's a company policy. Who knows, I never asked. But the point was that the nurses wouldn't appreciate it if she did it herself.
QSIITurbo··on OS/2 2.0, Summer ’91 Edition
Apple would've gone nowhere with their pricing with NeXT. NeXT station was basically a Silicon Graphics workstation for developers and cost 8000, about four times as much as a high-end gaming PC that would run Win31 Word and Excel with no problems. So not a computer for the masses. I see the pricing problem happening to OS X at the moment.

MS has excelled in getting price, (backwards) compatibility and system requirements correctly. That's why they moved slowly at the time and still do in some regards.

OS/2 was merged into Windows NT which is what almost everyone is using on desktop these day. IBM even tried giving OS/2 for free (Warp or 2.1, can't remember, you could get it by sending a coupon to the publisher), but the lack of compatibility and system requirements killed it. I remember booting it on a 486/33 + 8MB, yuck. Contrast that to almost instant startup of DOS and the requirements of an ordinary user.

Also, IBM sold PS/2 (or something like that) with OS/2 preinstalled... It booted like forever and there was zero software available for the home-user.

QSIITurbo··on Ultima VI
Yeah, the western RPG genre had become these "inventory management" or "taking notes" games. They made up for the lack of enhancing and balancing combat and developing AI with these gimmicks. Ultima series is one of the worst: you have to manage food, light sources, runes, mantras, finding spells, spell ingredients, spellcasting, moonstones, moongates, gems, two extra alphabets, mapping yourself, and so on and so on. When you start to think about it, it's like having a second job just to kill the bad guys.
QSIITurbo··on Ultima VI
The menial tasks you can do in these games were a mistake in my opinion. For example, the overly complex UI in Ultima Underworld and Ultima VII was more or less just to facilitate the use of these items that you maybe spent 1% of your gaming time on (fishing, putting fuel into light sources, baking bread, selling them, yay! Who gives a crap). UW could have been a real forerunner if it had had a simple mouselook with streamlined combat and without the useless complexity.

Modern games have given up on that for which I am very grateful. Diablo and Black Isle games were the real forerunners in the KISS principle that revitalised the dying 2D RPGs.

QSIITurbo··on A.I. vs. M.D.
Both your doctors were correct: high fat diet is unhealthy and vitamins don't help cancer (unless you mean help it grow).
QSIITurbo··on Samsung’s biggest challenge now is Google software, not Apple hardware
I'm actually considering just buying a new battery for my Note 3 and S8+ is way out of my price range for maybe two years and the competitors are offering interesting phones at very low price-point. I'm amazed how ahead of time the Note 3 was and is such a perfect phone still. (For example a lot of cores for sharing network connections etc.) It only lacks the fingerprint reader and water-proofing that I'd like. And I'd rather have a phone that allows easily replacing the battery but we'll see.
QSIITurbo··on Samsung’s biggest challenge now is Google software, not Apple hardware
As a user, my experience is the opposite (Note 3). And that's what matters in the long run. The question is more whether they can keep up bringing new stuff into their high-end phones. Apple was not able to do so.
QSIITurbo··on Samsung’s biggest challenge now is Google software, not Apple hardware
Agree with this one. Chrome has a much worse UI (hides commonly used stuff under menus) than Samsung's "Internet" and is just as fast. At least File Browser, Calculator are good. Samsung Smart Switch is just awesome.
QSIITurbo··on Going Under the Knife, with Eyes and Ears Wide Open
It says in your link that it's equally likely in general and regional anesthesia. Moreover it says it's more likely in cardiac operations where blood flow into the brain is disturbed. I assume this is very rare then.
QSIITurbo··on A hot bath has benefits similar to exercise
Ugh, your comment is so stupid I can't even be bothered to think of a proper reply.
QSIITurbo··on A hot bath has benefits similar to exercise
This is the correct answer. Mobility is more important than exercise. You'll lose mobility by breaking bones.
QSIITurbo··on A hot bath has benefits similar to exercise
Not really. Take your 30 minutes of exercise per week that will reduce the chance of dying by 1% (2% is for the forrest gumps). Let's say you can do that by spending 60 minutes a day (changing clothes, getting dressed / undressed, showered and so on). In a 52-week year that will amount to loss of 156 hours of your life. For 8-hour work days that's 19.5 workdays. A good vacation's worth! No drug is allowed to do that.

And if you break your ankle or break your wrist or elbow when exercising, it'll never be as good as new.

QSIITurbo··on A hot bath has benefits similar to exercise
Exactly. 20% or 40% sounds really big. In reality, you're maybe lowering your chance to die (during some time) by less than 2% by exercising almost constantly. Now, if you're not enjoying exercise, or feel exhausted after exercising, you actually reduce the amount of "quality life" by exercising.

If exercise was a drug, they'd never allow it on the market.

QSIITurbo··on A hot bath has benefits similar to exercise
I recommend you take basic university statistics. Especially study efficacy vs effectiveness so you might have an idea how you're being mislead here.
QSIITurbo··on A hot bath has benefits similar to exercise
Um, no. 3.84% to 2.08% being an approx 40% reduction is exactly what is being avoided currently in research since its reduction of less than 2 percentage units. Imagine a medication that has a "20% and 40% reduction in mortality": You'd have to have more than 150 people treated to the max to save one person vs other cases (more than 75 to save vs no medication). Not 5 as your percentage implies. Not very efficient way to spend money if you ask me.
QSIITurbo··on A hot bath has benefits similar to exercise
It doesn't change the fact that if you take approx 150 from each of the activity groups, the cohort study will tell:

Approximately 5 from the "slobs" will die.

Approximately 4 from the "moderate exercise group" will die.

Approximately 3 from the "forrest gump group" will die.

On a personal level, to me these groups are more or less the same in terms of mortality, but somebody marketed the 20% really well.

QSIITurbo··on A hot bath has benefits similar to exercise
Yeah, it has its weaknesses and also from my comment below: "So I read the study for fun and the non-adjusted rates are 3.84% death rate (cohort study) in no exercise vs. 2.35% in 1-30 minutes and 2.08% in more. And that's not adjusted for pre-existing conditions if I understood correctly. So meh. Even though 20% and 20% sounds really great!"

I didn't find anything there for longer periods of time but odds ratio is not a great indicator if your base chance of dying is already really low. Or maybe spend the whole week exercising to squeeze that last 0.1% out of your chance of dying.

QSIITurbo··on A hot bath has benefits similar to exercise
I really don't understand those numbers. Surely mortality is 100% regardless of exercise. How was the study designed?

So I read the study for fun and the non-adjusted rates are 3.84% death rate (cohort study) in no exercise vs. 2.35% in 1-30 minutes and 2.08% in more. And that's not adjusted for pre-existing conditions if I understood correctly. So meh. Even though 20% and 20% sounds really great!

QSIITurbo··on The beginning of Git supporting other hash algorithms
No it's more than that. "unsigned char[20]" already has at least three potential points of failure (and why isn't it uint8 anyways). Moreover, it'll be referenced as unsigned char*, which opens another can of worms. And oh, by the way, have fun searching all references to sha1 on your source code now that you weren't pro enough to create a type for your object ids / hashes.

I'm guessing it's part lack of skill in design, part bad software development tools (uEMACS and makefiles or something), and part just being against c++ et al.

QSIITurbo··on The beginning of Git supporting other hash algorithms
Well, this whole mess proves that Linus was wrong. Typing "unsigned char [20]" everywhere is beyond amateurish to me in any case and raises a concern about the overall quality of code in git and linux kernel.
QSIITurbo··on Who Needs GPS? The Story of Etak's 1985 Car Navigation System
As for orienting the map, it's common practice in sports and army at least. You're _supposed_ to orient the map according to your surroundings and the direction you are facing. It's faster and less prone to errors.
QSIITurbo··on Acute exercise increases expression of telomere protective genes in heart tissue
Yuck. Just the normal nutrition crap with no real studies to back up the claims. The biochemistry may be sound to a point but the conclusions about ageing and positive health effects of "x, y, and z" are there on the hyperbole. Zero respectable publications where they show that people with "diet x" are healthier than the average population.
QSIITurbo··on Why are all Windows drivers dated June 21, 2006?
From what I can tell, the "solutions" presented here don't actually solve anything, make things a lot more complicated, and just open new cans of worms. For niche cases there are always good workarounds.
QSIITurbo··on Why are all Windows drivers dated June 21, 2006?
Just out of curiosity: Have you ever considered just buying a new controller? Spending your time on troubleshooting drivers doesn't seem like a sensible decision from the time=money point of view.
QSIITurbo··on Big Sugar’s Secret Ally? Nutritionists
Keto is the absolute worst you can do as an athlete since carbohydrates are required for fast recovery. No professional athlete would be on keto while training. The idea that an athlete should have even slightly over 1g/kg of protein intake per day is correct. However, over 2g/kg/day poses a risk of permanent kidney damage.

Moreover, losing 4 kgs or more of fat in a month increases the risk for cardiovascular disease: the blood cholesterol levels of the subjects may rise to unhealthy levels. Some are resistant to high cholesterol, but statistically it's a risk.

QSIITurbo··on Big Sugar’s Secret Ally? Nutritionists
Since you're an expert in the field: How does the insulin for a diabetic patient differ in its fat-storing capabilities from the normal insulin secretion of a healthy person? I agree that there are metabolic differences in people but rarely non-pathological and rarely not age or body mass related. Pathological cases where the difference in metabolism is indicable, we already know how to treat / be unable to treat them. Moreover: type I diabetics tend to be lean / normal weight. So the question is: what is the metabolical difference you are referring to?
QSIITurbo··on Big Sugar’s Secret Ally? Nutritionists
The medical scientists / professors I know have gone through several revolutions in medical science (statins, diabetes treatments, resuscitation procedures, surgical procedures, dialysis, etc.). I wouldn't call them unable to change their habits. In fact, they are few of the smartest people I know.

I don't know about the margins of food, but I consider preparing food from the basic ingredients somewhat time-wasting and costly (when I actually order or buy and prepare them myself). As they can have fine nutritional values, I don't think processed foods can be generalized to be bad per se.
