> I would have thought that criticising HTML5 and providing valid reasoning means you think negatively about HTML5

Dissent is the highest form of patriotism. Not offering criticism isn't supportive, it's religious. Being willfully blind to huge holes in necessary support won't make HTML5 better.

> The problem is, the author hasn't backed up anything.

It's not a research paper for a scientific discovery. It's an opinion on the state of HTML5. The OP doesn't need to back it up since proof of his points are rampantly apparent and readily available, cognitive dissonance excluded.

If you want HTML5 to get better, you should ask that it is better. Turning a blind eye is just foolish.

It might be that he is referring to Doppler VOR (http://en.wikipedia.org/wiki/VHF_omnidirectional_range), although I'm not sure how this effects interference scenarios.
The whole concept of "statistically significant" has to go imo. It causes much confusion and influences experiment design (because in short it focuses on obtaining maximum amount of measurement in unchanged conditions instead of measurements which maximize information value), All that in the name of some arbitrary chosen threshold for statistical significance.

Startup Quote from Joel Spolsky, Co-founder, Stack Exchange
Unless I'm missing something, this article only discusses tweets by language, not geography. Many Europeans use English on social media sites given the cosmopolitan nature of Europe and the likelihood that, if there is one language they have in common with friends from other countries in Europe and abroad, it is English.

I'm guessing there's a few lesser spoken European languages in that "all others" category.

Yes, it reads that way, but if you're just reading the words, you're missing the point. It demonstrated passion for the product, attention to detail, and the ability to get something cool done. Those are things I would hire for.
I have no idea how or why you've reached any of these conclusions; but in any case - good luck to you.
The difference between n^2.373 and n^2.376 (i.e. n^0.003) is about 1.3% for n=100, 2% for n=1000, and keeps getting better for large n.

I'm excited about ARM processors for low-power applications but I can't see ARM replacing x86 processors (even in the consumer space) until ARM performance is comparable to x86 performance. Right now the slowest MacBook Air is 6x faster than the iPad 2; until the difference is 2x or less I just can't see companies or consumers switching to ARM.

It matters only in so much that you needn't short a Li-Ion battery to have a violent discharge of heat energy.

Shorting any battery will cause it to heat up, but lithium is a potent alkali metal. It reacts violently (as in fire and possible explosion) with water. The moisture in your skin will do just fine. Contrast this with other battery chemistries such as nickel-cadmium, which are practically benign by comparison.

Here's a great video illustrating the results of dropping bits of various alkali metals in to a bathtub full of water:

Hey HN, where do you go for good ideas?
I'll admit this is sort of a vague question, but I think it will make for more interesting conversation. Where do you find interesting ideas for things to work on? Universities? Friends? Internet? The shower?

I'm finding myself in something of a creative slump, and I'm eager to find out what's happening on the frontiers of computer science and entrepreneurship.
I'm pretty sure about that, given that the same author has been quite harsh on the FAA about other issues (such as crew rest time). Edit: http://www.salon.com/2008/01/04/askthepilot259/ - hardly what I would call propaganda.

Marco Arment is from my understanding a leading iOS developer, and a paragon of what it means to be an iOS developer (His app, Instapaper, has tasteful design, is easy to use despite offering many features over multiple platforms, it just works, etc). He also releases a lot of information about instapaper which yields insights into the iOS market in general (versions of iOS used, sales by device).

He's become an important tech blogger, too, with several recent front page HN posts (recently, his review of the Kindle Fire). Given his general support for Apple products, this post represents an important shift in his perspective. Maybe its not front-page HN worthy, but you should probably know him.
It was probably down-voted because it asserts the fallacy that bullets are some sort of acceptable substitute for pepper spray. We'd rather have neither.

Non-lethal weapons are a hotly debated topic in the area of civil liberties. When you start looking in to the effects of non-lethal weapons on police behavior [1], the root of the issue becomes more clear. The two decision paths stemming from the question of "Should I shoot this person, likely resulting in the end of their life?" are much more clearly deliniated than when the weapon is non-lethal.

Thank you! I've had this same feeling for a long time. It strikes me as odd that probably a lot of the same people that would find it unacceptable to write cryptic C code with one-letter variable names, find typical math notation/jargon to be completely fine and legible. If code is so important that we go out of our way to make it comprehensible to future maintainers, why don't we have the same feelings about math? (which I would argue is much more important for people to comprehend, seeing as how it's the core foundation of all of science)

Personally, I'm really into physics, so I've always really wanted to like math so that I could delve deeper into the subject more easily. It's not that I'm terribly bad at it, but most math texts are so obscenely terse and cryptic, that it makes you wonder whether the authors are actually even trying to teach people about what they're talking about...

Use his skills! Just because it's a tech startup doesn't mean a superb salesman isn't useful. Find an idea that puts both of your skills to work. Most people shy away from products that require cold calling to find customers. You have an open field!
It's good for customers in the short term, but it's not good for anyone in the long run: they're sweating their suppliers, all the way back down the supply chain (read: to authors like me) and sooner or later they'll put their suppliers out of business.

As a reader, this does not strike me as against my interests in the long run. I get books teleported to my Kindle instantly -- what isn't to like? (They're cheap, too, but that isn't a huge win for me. I'd pay twice as much as I do currently without thinking twice.) A shame about Charlie's publisher. They've sold me minimally $200 worth of product in the last year, I could not tell you their name if my life depended on it, and they bring precisely zero value to me relative to any other publisher aside from having signed Charlie. If Amazon signs Charlie instead, it will be literally impossible for me to identify any way in which my life changes at a consequence.
deviantArt seems to be a place like that.. Altough it's a lot more art-oriented.

There's also the safety issue of the items not being stowed which are then made projectiles when a takeoff is aborted or the runway is overshot on landing. I don't want my Kindle embedded in someone's head because I had it out during landing.

Right on - I usually use my Kindle, but also use the Kindle Reader app on my MacBook and on my Droid.

BTW, I have bought a lot of Charlie's books, all in Kindle format.

I really like publishers like O'Reilly and Manning that provide both MOBI and ePUB formats when you buy - that is real respect for customers.
The author, Virginia Vassilevska Williams, is married to Ryan Williams, who last year proved a major result in circuit complexity lower bounds (NEXP is not contained in ACC0). It's interesting to see that both of them are making important discoveries, in different areas of computational complexity.
As I've said in other contexts, I simply will not purchase a subscription to each of ABC, NBC, CBS, Discovery, HBO, Showtime, etc etc and those guys can just forget that dream.

Books are a bit different than those media wars, though, because they are something one buys in discrete units. If I can pop the name of the book or author into Google and land on one or another reasonably well-done website by the publisher, and they come to some sort of agreement on DRM in the manner of something like Bluray (which is to say, it is not mandatory that every company uses its own DRM and there is prior art for industry-wide agreements), it matters much less to me that I buy one book from X and another from Y. It isn't harmless, but it isn't the fatal objection I think it is for any industry with 15 different entities all trying to work out how to carve a $9.95/month subscription fee each out of me.

Where I feel like video needs something like Netflix or Amazon to serve as a subscription aggregator and to manage cash flow conversion from subscriptions to per-watch fees transparently, it seems like publisher websites and Google (as a search engine, not some new service) might be sufficient for ebooks.

If the book publishers get their act together.

Although I'm a full-time programmer, the best and worst job I ever had was as a bookseller at a major bookstore chain. When I first got there, my coworkers were passionate about books--it was something the store manager looked for when she hired. It was a fantastic place and time to be there. When the store manager was promoted out of the position, she was replaced by a more corporate type who had different hiring criteria. In a little over a year, she turned the place into just another job because she hired people that had no passion. The ones that did left. It became another 9 to 5, and I think the store suffered because of it.

This is really more AMD throwing in the towel vs. Intel. It's really disappointing to see a competitor leave such an important market. I'm much more disappointed to see the X86 market go from 2 to 1, than I am happy to see the ARM market go from 4 to 5.
Forgive my ignorance, but does anyone know any real world examples where something like this might improve a certain type of work?

I'm sort of fuzzily half-assedly thinking this might be applicable to image - and by extension video - work but maybe that's not the case at all. I want to be more excited, please enlighten me. :)
I think it's more a matter of the bulk of consumer "micro architecture" usage shifting from computers to "devices", a la tablets, mobile phones, cars, appliances, etc. Right now, we frame our picture of consumer micro architecture as devices that look or act like a computer, but that vision is changing rapidly. Cumulatively, these devices far, far outnumber computers.

I find I have my best ideas when I'm not trying to come up with an idea at all. That doesn't mean you shouldn't look for inspiration, but I think a large part of forming an idea is to let your brain be disengaged. Here's something I shared on HN the other day that touches on this concept, but with better evidence:

http://fairobserver.com/article/self-referential-thought-neu...
The quote doesn't imply that improving your product is the only thing that works. The quote is that nothing works better than this.

Besides, I think it's fair to say that Microsoft generally improves its products with each iteration. The only possible counterexample to this that I can think of off the top of my head is the XP -> Vista transition.
You mean at most 2.3727. It's not really a safe assumption that the bound will shrink asymptotically to the real omega as far as I know. But it is suspected that higher tensor powers may drop the exponent slightly.

I believe there are approaches related to other constructions in group theory, such as the wreath product, which may eventually lead to better results. It's just a huge unknown at this point. (My knowledge of these techniques can be written on the back of a postage stamp otherwise I'd try and provide more detail.)

One certainly hopes that higher and higher tensor powers are not the way to get omega = 2, as the algorithms just become more and more complex.

Someone may correct me if I am wrong but I think it is still not known even what the best algorithm is which breaks matrices up into 3x3 and whether one exists with better complexity than Strassen even (which breaks the matrix up into 2x2). A huge number of CPU cycles have been used trying to find the best algorithm using a 3x3 decomposition.

That's an extremely good point that I really should have mentioned, since some of the United States' issues with it pertain to the exclusive economic zone. Although a non-issue when dealing with the contiguous zone, moving a ship/artificial island outside of the contiguous zone may implicate it. I'll have to look some more into the United States' stance on Articles 56 and 60, which deal with the EEZ and artificial islands, respectively.

How am I to tell whether leaks are from Firefox or Firebug? What I know is that after a full day developing Firefox will use 800MB of RAM, and the only way to get rid of that is to close the entire process. I use Firebug heavily and I know that _something_ is leaking somewhere.
The short answer, I believe, is "you don't". Try DMCAing them, but it doesn't always work, and when (not if) it doesn't, sue.
I think of it as a bias towards suspecting incompetence rather than a bias towards suspecting malice. I think people are too quick to assign narrative to situations, and malice is a stronger narrative than incompetence.
You could certainly use Django or Flask to implement the same functionality, but I was trying to use the word "problem" in a wider sense than that.

In my real word scenarios I'm often faced with requirements of vastly different scale and highly variable deadlines. I also have to consider the likelihood of the code being added to in the future - potentially by someone else on my team who is less experienced by me. All these things taken together - and more - constitute what I am calling a "problem".

My Django apps all run to thousands of lines of code and are well documented and thoroughly tested. It's fairly routine for the lifecycle of these apps to stretch over years, with an ongoing requirement for maintenance and new features. If I need to create a social network for my company which ties into their existing information sources, then Django is where I start.

On the other hand, my Flask apps tend to run to the small hundreds of lines of code. They're usually hacked together quickly for a very specific use case and there's very little in the way of documentation. They might not even work correctly except in fairly limited circumstances (e.g. no time to write form validation code) and might get thrown away after being used a small number of times. If I need to create a tool to allow users to purge parts of our Varnish cache then Flask is where I start.

Perhaps not everybody uses the two frameworks in quite the same way, but I find that they complement each other well.

My interesting ideas almost always come to me when I'm trying to sleep or when I'm in class. However, the subject of my idea is almost always unrelated to sleep or to the subject of the class at hand.

I think the meat of an interesting idea comes from exposure to the widest possible variety of environments, and the intersection between them. An obvious pattern for programmers which fits this criteria is an app idea arising from the intersection of knowledge about software and knowledge about something entirely unrelated, eg. patio11's Bingo Card Creator. (Yes I know, "interesting" is subjective.)

The ideal "idea generating formula" for me has therefore become seeking exposure to interesting (no, actually just different) objects/places/people/ideas/pastimes/jobs/[insert noun here] and then waiting for my brain to make connections out of it while it should be focused on a lecture or sleeping.
I know many, many researchers, and very, very few who have published anything "groundbreaking." Meaningful, original, often even important, but rarely groundbreaking. There are different tiers of venues to publish in, just as there are different tiers of institutions to do research in.
