The code is perfectly clear and well-documented. In most of the cases, the problem is that most software engineers have no clue how the hardware (or operating system) their software runs on actually works. Consequently, they are oblivious to potential side-effects of innocuous-looking code changes that the original author accounted for. There is always documentation explaining the optimization and intent but many engineers do not have the background knowledge to understand how that is achieved. The code optimizations are easy to understand if you know how to optimize code. The problem is that most software engineers do not, nor do they know what optimizations look like even when the code itself is easy to understand. So the best we can do is annotate that code with the fact that some important optimizations were made there and to understand the nature of those optimizations.

Also, it is difficult to impossible to unit test many optimizations. Many of them are about minimizing interactions between concurrent but unrelated processes or minimizing the latency of some code path. The functionality can be correct and fast in unit tests and the run-time behavior in operational environments still be pathological because of potential interactions that are nearly impossible to replicate in the unit test environment. You can run simulated workloads but those are much more expensive to do and for any kind of non-trivial system the coverage will be poor relative to the kinds of problems you may have.
Only if anecdotal, I find people from English speaking nations outside of North America being incredibly opportunistic in these things.

This observation purely emerges from my experience.
The scientist in the article claims that Mars still has tectonic movements which strikes me as odd. I thought the consensus on Mars tectonics was that it has stopped a long time ago. If there is movement than the core must be liquid and moving. If its core is liquid and moving it would generate a magnetic field. Just like our liquid core creates the magnetic field around earth.

The thing is.... Mars has no significant magnetic field like we have around our home planet. It's also the reasons why more of the sun's radiation gets through to the surface on Mars than on earth. Our magnetic shield deflects radiation, Mars does not have that shield.

It's believed that Mars lost it's liquid core because it's smaller than earth and therefore has a higher surface to volume ration. That caused it to cool off a long time ago.
Even with privacy off I won't get or keep any personal information just basic usage stats that will help me understand how users are using the application. This is something that I value the ability to do, it should be beneficial to users as I can improve the product so I would prefer not to give it up for free although I do want to offer people the option of not having any data sent back.

Things that I plan to monitor when I have time to set it up include things like frequency of use, number of lists, number of items, maximum depths of lists. Whether it is an iPad or iPhone it is being used on, what the default language is, whether they are using the email features and what items they have purchased.

I will have a persistent ID for each Install so that I can track usage overtime and try to identify if people stop using the app but it won't tie directly to any person or even device that could be identied by any means outside the app.
It's hard to tell exactly how it will affect YouTube, especially since we don't know how it affects results at all. I suspect the deciding factor will be how google knows about the takedown requests, since it will almost certainly treat YouTube specially. Furthermore, it's possible that YouTube is linked so much that the DMCA requests have a negligible effect.

Personally, I think this is a mistake by Google. No reason I can think of makes sense - this won't appease content holders for long.

I think we read this sentence differently.

>>The earliest known use of "computer hacker" described a criminal act

I read it to mean that the earliest recorded use of the term computer hacker was when it was used to describe a criminal act, Where as you seem to have taken it to say the earliest recorded use of the term computer hacker in the context of a criminal act.

Given the context of the rest of the article, I think I am more correct.

The selling DVDs part may be it. If it's always freely available on Youtube to watch, why would anyone want to own DVDs?

Who knows?!

Edit: I just realized, India doesn't seem to have as much broadband internet penetration as the rest of the world. Where as it most definitely has a very high TV penetration.

Now, we see that in a lot of countries, USA for example, people are moving away from TVs solely to video streaming.

So I guess my earlier speculation of high viewership on Youtube might actually be completely wrong. It might be because the viewership on Youtube is low enough not to affect the main ratings.

Maybe they will face the same problems as the rest of the world once broadband becomes a bigger deal and a much larger percentage of people stop watching TV.

It could be an economic reason, as in increasing the sense of flyer 'security' (despite being an utter failure). Consumer thinks, "I exposed myself so that I can feel safe thinking everyone else was also exposed." Consumer is invested.

It could also be a political barometer to our collective response to an increasing police state.

This is a joke right? I almost stopped at the first sentence.

There are many studies detailing the inefficacy of cardio for weight loss for various reasons -- from Friedenreich (2010) which actually compares cardio vs. non-cardio groups... to Willbond et. al (2010) which talks about the overestimation of caloric expenditure.

Not to mention the meta-analysis from last year: http://www.ncbi.nlm.nih.gov/pubmed/21787904

But I guess you prefer observational, correlational studies instead. Of course people who run marathons are likely more fit. Derp.

Guess what, those who drink diet sodas are more likely to be overweight. I guess diet sodas make you fat?
I don't go on reddit much anymore, but the /r/paleo community is almost directly responsible for my 75+ pound weight loss. They easily supplied the basic knowledge & a sense of community.
This has never been the case for me. Perhaps you should be more discriminatory when it comes to choosing a place to work?
It's funny, the first time I heard this, I thought it was a really neat thing to say. It's like wishing somebody a good day, weekend, evening, whatever, not worrying too much about the specifics. The kind of laziness that seems more sincere.

Now it's become just another greeting, part of our business culture. The fact that it's probably in some ESL textbook kind of kills the intent. Probably a sign that I'm getting old.

Anybody know what the young people are saying to each other nowadays? Aside from racist, homophobic slurs, I mean.
Entertaining (though I've already read this one...).

I have a more interesting game I play with bank security questions that's more useful, though -- and applies to the most common usage (where the bank provides the question to you).

Simply this -- for each question, imagine how easily you could guess the answer even knowing nothing about the account owner. I'm not talking about real analysis here, just roughly mapping out the answer space.

For example, "In what city/town did ___?" is a common question. Well, if it's a US bank, probably you're dealing with US cities, and there are fewer than 20K. (Already, whoa: a three character alphanumeric password has 10 times the possibilities). Then of course cities should be weighted by population, so since NYC is biggest... well, New York has 8.3 million of the USA's 311.6 million population, the answer to this question will be New York City about 2.6% of the time.

"What's the first name of your [specified grandparent]?" is another good one. How diverse are first names, generally, particularly a few generations back? Of course there's a long tail, but otherwise... not that diverse, and it's trivial to find stats on most common names in the early 1900s. I've never chosen this question even before I started thinking hard about security, because it was blazingly obviously a bad question -- the banks would ask for my maternal grandfather's name, and I was named after him.

Fun, no?
On Earth the tectonic plates are only 'crust thick', except for areas where they are subducted into the mantle. A liquid substrate is not a requirement for plate movement.
Yeah, we're told by their customers that they do two things that are particularly egregious:
1) They force non-compete contracts
2) They treat their customer data as theirs, essentially leveraging the filmmakers submission information against you.

As a result, they've gotten incredibly lazy with their product. It's a shame for filmmakers and the festivals.
> Why is it that both Atkins and Taubes got so fat on very low carb diets while Japanese people traditionally ate (and many still do eat) rice at every single mean, lunch, breakfast and dinner?

Because eating a lot will make you fat, and eating a little will make you thin. Whether you eat proteins, fat or carbs, you can gain or lose weight depending on how much you eat.

I haven't studied it very much, but just eating less works for me.
I'm very happy that Steve is such an Emacs fan. I have little doubt that the Emacs support will be top notch when this hits the street.
The average person and the population in general doesn't need advice any deeper than the "shallow" content found on Reddit in order to live a healthy lifestyle, and because the information is often so easy to swallow, it makes new members feel infinitely more comfortable.

Sally next door doesn't need to know about carb-loading and iso-whey protein shakes. Forums all about that stuff are incredibly intimidating and geared towards individuals who typically want to go above and beyond what is considered a normal healthy state.

Reddit offers easily digestible information with support from a huge community. I'd argue that's all you really need to fight obesity.
there are 2 different purposes here. the high saturated fat diets - yeah that will drop weight. No one really knows what the long term effect on cardivascular disease (i.e. damage to arteries) will be, since they haven't been practiced for the several decades it takes to find that out.

^ this is exactly what I am saying.
I just have to mention that while doing what is "optimal" might seem like hacking health, it really isn't in terms of total gain. A strict diet and gym workouts are almost the opposite of appreciating food and sports. Learning to cook, socializing over dinners, playing sports in teams, learning new things that you can actually use, living a sustainable life etc. is what's going to give you the most value in the long run, not living like a "sober food alcoholic".

I don't mind people trying to hack weight loss, but don't forget that the science behind it should be for your situation, that there's a huge survivor bias and you'll need a long term plan as well.
It is not a joke.

Firstly, meta-analysis are generally amongst the worst things to go off (study selection makes it very difficult to control for a researcher's expectations). The link you provided doesn't even say how much cardio the subjects were doing.

Secondly, the studies I cited were massive and far better controlled than most. Feel free to offer a link to a larger and better controlled on if you can.

Thirdly your link, despite its problems, supports my argument. Participants reduced their waist circumferences by 2cm in 6 months!

Interestingly the first search result for "Friedenreich (2010)" is your own tweet, but looking further I found that he recommends exercise for cancer prevention. In fact, this presentation I found in the first page of results recommended more cario than any other type of exercise:

"Nothing else."

I find this doubtful.
It incentives spam.

I have less of a problem with comments containing referral links since that's clearly the author's opinions, but I see submissions should have less blatant commercial interest.

HN already frowns upon self-submission of personal blog posts (if it's interesting enough for HN the argument goes, it would be submitted by a 3rd party).

How can I trust a website recommendations from a website like Coding Horror when every Amazon link generates a commission. It's encouragement to sell expensive products rather than more suitable ones.

I generally remove the referral query from URLs when I click through.
The main reason I avoid tables is because of my previous experience. Tables, and especially nested tables that wrap the entire site, would be noticeably slower when changing styles dynamically. For example, changing the positioning of an element on hover when the element is deeply nested in divs. The second I removed the tables, this was calculated much faster. This was about five years ago so I have no idea if this performance concern exists any more.

Separation of concerns is a design choice. I'm not sure what context you meant, but if you find that it's overkill, you can make that design choice that it's unnecessary. In general, I find separating these concerns leads to cleaner and more understandable code, but I can certainly imagine situations where your argument can be made, especially on sites that are simpler.

Some people do believe quite a bit in purity and believe the markup should just describe the data. I agree that it's nice but doesn't always work out in practice. This can get taken too far. For example, I've seen complex workarounds for centering vertical alignment when they could have just thrown a table, but they wouldn't do it because a table is for tabular data. In this case, I felt that the table would have been easier to read and understand. Again, this is my preference and others may disagree.

TL;DR; - It depends. And performance issues back in the day.
I have been a professional in the game industry for 17 years. Every one of them someone was saying it USED to be great/ creative / exciting etc. Whatever! Someone is always doing something cool, someone is always doing something lame.
Interesting but I am not getting it. How does plate movement happen without a liquid substrate?
I'm confused. You "disagree", yet I don't see anything that really disagrees from my post.

> One of the reasons for the ongoing conflict in Xinjiang is that the local Uyghur, Kyrgyz, et al. don't look Chinese and don't pay any lip service to the "superiority" of Han culture.

If Han Chinese ever start intermarrying with Uyghurs in greater numbers this will change. Given the ratio of males to females in the mainland, I would guess that this will happen way before a sexual revolution in China (which the lack of imo is the reason for the gender population gap). I feel that this is the same reason that Han chinese started to intermarry with both Mongols and Tibetans.

I agree completely. There's also a mountain of evidence to support the health benefits of good social connections and a low stress life. Dancing is one form of cardio that I've seen come up again and again in papers about warding off lifestyle-related ailments.
It's Burning Man--the whole point is to have a bunch of disconnected ideas and claim that they'll save the planet.
Well done on your results. I enjoy VLC myself, but must say that I don't find the keto subreddit very worthwhile. The community support aspect is undoubtedly beneficial for those in peaks and troughs, but aside from that, what remains seems to mostly be "off-limits-imitation" recipes, and chest-beating about eating a bucket of low-quality bacon or whatever.

I guess what I'm saying is that the fundamentals of this type of diet are self-contained enough that just getting on with it once up and running is worth considering rather than staying hooked in to the ebb and flow of a community.

Friedenreich found that the test group lost more weight than the control group as well via. cardio. Yet I posted it in support of my argument anyway. Why?

It took an average of 35 hours of cardio to lose 1 lb of fat.

I'm not saying that it does not cause weight loss. I am saying that it's ineffective. Of course cardio will cause some weight loss vs. doing absolutely nothing. Of course it's good for your health. No one is arguing that.

Then again if you're saying that someone should run 1 hour/day for 5 days a week... which is unrealistic for 99% of the population, and unnecessarily complicates weight loss (not to mention makes it unsustainable)... then you probably don't have a problem with 35 hours to lose a pound.

I respectfully disagree. Choosing to use a graphical IDE or a terminal based editor is a matter of personal preference; it's foolish to proclaim one or the other as universally superior. There are pros and cons to each, and they are fundamentally different in many ways.

Yes, vim is old, but it's not a web browser - it's for manipulating text (or in our case, code), the process of which has changed little in the last 30 years.

Before writing vim off, pair program with someone who is masterful at it and you'll see some if its many pros first hand. Yes, this may take (quite literally) years of use and customization to achieve, but no, it's certainly not something you can write off as obsolete or inferior.
Having a Beijing hukou helps but is not necessary. In China you always have other ways to do things.
No offense to the op but it sounds like he doesn't hustle. The app stores aren't the only place that people learn about games.
Yeah, I think those factors are a bit more important than counting syllables. Shorter is better, but clarity and memorability trumps that.

As a random example based on the tabs I have open, RockPaperShotgun is probably the most popular blog that focuses specifically on PC games. That's a lot of letters and five whole syllables, but it's also easy to remember. It's a good name.
That's the really obvious reason that everyone I know is afraid to start a company without getting the .com first.

But the OP makes a good point that it hasn't been as big a barrier as we have feared. Square, for example, is a superb name and I think they made the right decision to proceed with Squareup.com, even though I thought it was foolish at the time. Turns out they were right, and I was wrong.

Square is a damned good name. I wouldn't have had the cojones to proceed with the name, but they did, and good for them.
App stores will never remove the need for other advertising. Why not send review copies to the major Android, tech, and gaming websites, and see if they put something up? Why not put something up on AdMob? Why not do giveaways of the game? Why not put it on a competing app store? There are many legitimate answers to these, but relying on the Google Gods to sell your product for you is just silly. (Whether Google's cut is then justified is a different matter entirely.)
