Why not? The most important thing about a round planet in this case (and, in fact, the reason planets tend towards roundness) is that it means gravity is (roughly) equal at every point on the surface (and, in fact, at every point on any planet-shaped shell inside it, as well). On a cube, this is entirely gone. The centers of the faces would have the strongest gravities; the corners would have the weakest. For localised walks we wouldn't notice the gravitational changes (just as we don't notice them when we walk up a staircase), but if you made the trek from the center of a face to the edge, you will definitely notice.

It is not Flash's fault (just like wordpress modules poor coding is not PHP's or Wordpress fault). It is how it used.

I am glad in fact flash exists. I actually can install Flash Block kind plugin and 99% of "design mess" disappears.. If there would be no Flash, all these "designers" star put introduction pages with HTML5/Canvas/etc. And this is harder to block. =)

The issue, as I understand it, is that you need to know whether an identifier in certain contexts is a type name or not. C99 increases the number of contexts. Consider:

x * y;

If x is a type, this declares y as a pointer to elements of that type, if you're at the beginning of a block or in C99. If x is a variable, this is a multiplication in void context, unless you're at the top level of the translation unit. A somewhat more interesting example is

x *f();

which may declare f or call it, depending on what x is. Of course, lacking the ability to overload the multiplication operator, there's no reason you'd ever do a multiplication in void context, but it is legal.

If your lexer can distinguish type names from other identifiers, the problem is solved, and you can use BNF from there.
Just wondering if anyone else noted the irony ... of demonstrating the vulnerability of opening a random Flash video by ... posting a random Flash video. In a security article.

For gaming, mostly agree. Although I think that the pretty graphics are mostly for show, the real power will be the ability to customize gestures for any application, and the utility you get out of these gestures can well be worth looking down at a "mouse screen."

I'm imagining being able to manipulate a CAD model in isolation, freely rotating items in PowerPoint, redistributing power among throttle/lasers/shields using sliding bars (X-wing, anyone?)...I'm sure there are many more.

I'd almost argue to keep a normal track pad for dedicated cursor navigation and have the awesome set of touchscreens as a peripheral. Then have an amazing API for software developers to do creative things with it, and have an amazing UI for the layman to create their own mappings. That might get adoption for this type of thing going faster.

Easier to figure using the radius rather than the diameter. Volume of the sphere is 4pi/3 * r^3, volume of the cube is (2r)^3. Factor out r^3 and you get (4pi/3)/8, or 52% of the cube's volume is within the sphere.
The math on that is easy. The volume of a cube is X^3, the volume of a sphere is 1/6 * pi * X^3, so the difference is a little under 1/2 X^3. Put another way, the cube is (roughly) twice the volume of the sphere.
But those need to be clicked with the mouse. Having a top 10 list of extremely common hotkeys in an app is just a lot more discoverable (for the non-expert or first-time user) and much faster (for all users) than finding the right icon to click.

The GP's point is how do you know it's the "stereotypically Western looks" and not just the fact he's Western? Unless you claim that all Westerners look attractive to Asians (in which case there's no practical point in separating ethnicity from looks), the question to ask is how non-attractive Westerners are perceived.

I realise somebody asked a similar question about Graph Theory books already - http://news.ycombinator.com/item?id=865749 - but that discussion is two years old, and I was hoping there'd be something newer by now!

I call bullshit on this. If this had any truth to it, you'd think the entire C-level in every corporation would be overrun with "beautiful" people.

My limited experience with PEG parsing is that, in its simplest incarnation, it's not all that fast. Packrat parsing supposedly actually makes it slower in the normal case (where you don't backtrack much).

I still highly recommend it, though. It's very simple indeed (my self-compiling PEG parser generator is 66 lines of code: https://github.com/kragen/peg-bootstrap/blob/master/peg.md) and very expressive.
I think college is place to see opportunities and learn how take them. I really didn't enjoy college because was kind of lame (lame on learning some new languages and technology). But on basic programming, algorithms, math, physics, software design and logic were pretty good, sometimes boring as hell. But the thing is that you need to be patient. Languages comes and go but the principals are still the same. Also college is a great place to go to internships, student exchange, job/research, new ideas,innovation opportunities. Why? Because all those things are right in front of you. I wasted all that when I was in college and I'm working porting games (that is cool but I'd rather be creating them).
People think that because the high-end PC gear can't compete right now on price, design, longevity, toughness, etc.

For instance, this laptop can't manage to hit the MacBook Pro price point, and it's in a plastic case, as opposed to a single-piece slab of aluminum. Which do you think will hold up better? Who would you rather deal with for warranty repairs and replacement? Which company is more likely to still be alive at the end of the machine's life?
Reading the quotes from Razer in the article, it really makes me angry at the big PC manufacturers and happy that HP got out. Nothing Apple does is truly that amazing or innovative. The difference is that Apple actually has the balls to try to produce a high quality product. Not expensive for the sake of being expensive like Sony, but quality worth paying for. HP and Dell would rather sell low margin crap at high volume than try at the high quality game.

Go Razer! Glad they're the only PC company out there will the balls to compete on quality and innovation.
Some indication of who sued first would be useful too.

This appears to be very heavily influenced by x86. Why would a VM built in 2011 use an ISA stuck in the 80's?

EDIT: I'm not trolling, I'm seriously wondering. There's plenty of literature out there on the advantages of three-operand instructions, large register spaces, and RISC-type instructions. Was there a reason that x86 was used as a basis?

First thing that struck me was professional designers probably wouldn't use this, they're likely not willing to give up complete design control to a wysiwyg tool, and most have preferred cms and tools.

Off the top of my head:

If you're looking at the use case of locations sought via the mobile app, some suggestions would be: coworking spaces, barber shops/hair salons, groceries stores/supermarkets, running trails, and tailors. At least, as a higher priority.

Lower priority, but still important, would be places that don't need to be that close to me. Meaning, I would rather find a good, reputable service that is far away, than a nearby mediocre service. Such as: dentists, doctors, tax accountants, and mechanics.

I don't think I would need reviews for locations like retail stores, gas stations, and that sort of thing. So that wouldn't be important at all.

This is just a quick swag; I'm sure some of the prioritization could be argued. I hope this helps. Keep up the great work!

Trackpads are surprisingly well suited for FPS. I was with a bunch of programmers recently and we started playing Urban Terror with our Macbook Pros and we did fine with our track pads. It was more difficult to 180 in an instant, but otherwise aiming was almost normal.

Quality is obviously important. A $400 Dell laptop's trackpad would've been awful. Interestingly, a $5 optical mouse is a nearly optimal setup, which is why I doubt there is much attention on trackpads which cost much more.
I took the question (which I thought was rather absurd) and rationalized (and imagined it) this way: this cubic planet will not rotate, or it will not be cubic then. I took out gravity as we know it, and imagined I could just "walk" in it.

We walk on a sphere shaped planet, yet we do not "slide down" if we stand on the North Pole, yes? Same with a cubic one, as I imagine, the 90 degrees angle will be crossed without even realizing is there. I imagine we would perceive it as a flat planet.

As you can see, I did not take the whole thing too seriously. And that, of course, diminishes karma. So it goes. Cheers!

Google Maps does not require Flash.

I don't have Flash installed at all, and Google Maps works just fine without it.

Youtube also doesn't require Flash to download the videos. I use a number of youtube downloader programs to get the videos, and then use a native video player to watch them. Of course that's not how most people watch youtube videos. But there's really no reason why the service couldn't have been built around an some open downloading/streaming technology instead of Flash.

"it served and still serves brilliantly for sites made by the advertising industry."

Yet another reason to avoid Flash for end users like me, who hate ads and despise the advertising industry.

It's a narrow point, but the coincidence of "make the dynamic language fast enough that you don't need static types" and talk about equivalent perf using boxed math reminds me of the old saw about a sufficiently smart compiler[1]. Yeah, maybe the hotspot/jrockit wizards will be able to wave a wand and make everything fast. But, until the stars align in that department,[2] being able (and in Clojure's case, defaulting) to fast, static, primitive math is a good thing IMO, and really, really important to getting work done in certain domains today.

In the meantime, I greatly appreciate your pushing. :-D

My gaming machine is a laptop, for example. Until my netbook, it was my everything machine, but it was still my gaming machine. My tower serves underused as a server much more than a used computer. I _love_ laptops for their mobility and versitility.
That... doesn't really apply to EC. When I was a freshmen I thought of it as the "pot and people naked at parties" dorm. Which was actually pretty unfair, and there's a lot of variation between the floors there.

Like wpietri writes below, you should try marketing to a different segment. For example, try selling a slightly-modified version to the military for boot camp training in order to better track solider performance.
I think the reasoning in the experiment is a little flawed. Given that each task is so small, the cost of a context switch in the example is significant.

Most people multi-task because they are waiting for the first task to finish/ get rid of the monotony of doing the same thing over and over again etc. in which case multi-tasking can significantly improve output. Its kind of like the OS running multiple processes on a single core. If you are waiting for something, you don't need to hold up everything else..
No. "You're supposed to not worry so much." People are drawn to people that are happy. It's a very attractive trait.

For a dynamic language to add static types solely to get performance
seems like a hack to me.

Be that as it may, that's Common Lisp's approach as well. I never have added type annotations in Common Lisp, but I like the possibility of giving the compiler more info. (If I understand your point correctly.) The particularly nice thing is that you can get the disassembly of a function, to see what effects your changes have on optimization.

I keep all my most important documents in the "cloud"!
In particular, I suggest _Essentials of Programming_ Languages (http://eopl3.com/, AKA "EoPL"). Also, check out the _first_ edition - there's a really cool final chapter about compiling via continuation passing style (CPS, e.g. http://matt.might.net/articles/cps-conversion/) that got cut in later editions.

More generally - learn Lisp and/or ML, and go through any book that has you writing simple interpreters. EoPL, SICP, Appel's _Modern Compiler Implementation in ML_, "The Art of the Interpreter" (http://library.readscheme.org/page1.html), etc.
I've read through most of Learn You Some Erlang and I have to say that the second half of the book really starts to break down. About the point where you start to build the concurrent application the author's descriptions of what's going on become hard to follow and in some cases are glossed over with some new elements being left out entirely.

I was a little disappointed by the tutorial overall. Although the functional programming portion (first half) is quite good; well written and easy to follow.

I'm still looking for a great introductory text for Erlang.

1) this is not just "an antivirus". VirusTotal is a website where you go and upload a suspicious file, and they scan it. Also, this says nothing about the file being "public searchable", it says it's made available for security industry professionals.

"As a hacker rather than a gamer, the concept of a programmable set of LCD keys next to the standard keyboard is extremely interesting for native app development."

If you are a developer and you want programmable keys, don't sit around waiting for an expensive keyboard, reprogram the ones you've already got in front of you. As far as I know, all major OSes can already arbitrarily remap keys to any keystroke you like, and it's easy to pick up software to turn any keystroke into any action you like.

Are you really using PrintScreen, or SysRq, or ALT-PrintScreen, or any of the other combinations you've got unmapped and waiting to serve you?
I think part of the reason for the insane PC mouse industry is the relatively low cost of the periphreals and the (perceived) direct impact it has on the skill of the player playing a game. Where the PC gamer will drool over the 500$ amazing graphics card he can't afford, he can placate himself with a 70$ crazy ten-thousand button mouse.
