I did something similar around 2008: (but in Lisp!): https://github.com/smanek/ga Had to write my own bitmap processing library, since couldn't find anything fast enough off the shelf :-D Handled alpha blending, file i/o, etc (checkout th

If a lay person were to ask how they get back their dollars if they are stolen from their wallet, say due to a person mugging them, what do you tell them?

A disk seek (e.g., if you have more data than RAM and are using virtual memory) might take ~10ms. A packet round trip within the same AZ in EC2 is <0.5ms.

Just to clarify, it will definetly take me more than a day to write/profile/test the changes (especially since I'll be learning arc in the process). My hope is that it will only take a day or so to deploy it, once it's ready.

pg: I have fair bit of lisp dev experience. If, as a weekend project, I modified the HN src to use postgres and memcache would you consider using it in production? Obviously, I don't expect carte blanche prior agreement, but I wouldn't want

I think so. On a several decades/century scale it's worthwhile to funnel at least a few percent of GDP into basic science research[1]. But, in any given quarter/year, it's almost certainly a net loss. The trick being that every few decades,

For algo/datastructures, CLRS ( http://www.amazon.com/Introduction-Algorithms-Thomas-H-Corme... ) is the gold standard. For OS's, Tanenbaum ( http://www.amazon.com/Modern-Operating-Systems-Andrew-Tanenb... ) is popular. 'Math' is broad - if

also offtopic: 'voracious vocabulary' probably doesn't mean what you think ;-) (you're probably thinking 'voracious reader') I like to use HL Mencken as inspiration.

Dan was awesome. A few years ago, when I was an undergrad trying to raise money for my first startup in Boston, he was a huge help. Took the time to grab a couple meals with me and explain how things worked, introduced me to angels, and was

My per-site hash is only salted with the site's name. Hence, there is no state stored on my machine. Personally, I use (and prefer) LastPass to this approach.

Actually, Google Translate was an enormous leap forward in machine translation quality. It won a number of awards for its astonishingly good performance. And its design premise is that you can use really simple algorithms if you have crazy

Woah - I've used those docs dozens of times and never realized that the demos were interactive. I just assumed they were static examples. Thanks!

tip: the original meaning of a word doesn't necessarily have any relation to it's current meaning. I assume you didn't know about the etymological fallacy ( http://en.wikipedia.org/wiki/Etymological_fallacy ) when you used it. Now you know!

I don't think any GC scheme could work with that. Languages that allow pointer arithmetic like that basically can't be GC'd. The problem with an imprecise GC is that having an integer that looks like a pointer, could prevent an object from

There was some back-and-forth between Zed Shaw and DHH that I remember being interested by at the time. Zed deleted all his posts - but here are some places to get started: - Shaw's opening volley: http://web.archive.org/web/20080103072111

Yep, that's basically it. It sounds crazy (and it is!) - but it often works reasonably well in practice. SBCL (one of the most performant Common Lisp implementations) has an 'imprecise gc' that works the same way - and I've seen reasonably

Hotspot is the most commonly used JVM impl I was referring to. Last I looked into it (probably a year ago), some of the graphics libraries it includes weren't open source - but everything important (including the JIT) is. The patent issues

I think Java is a pretty bad language, but most of your points are provably wrong. You're either grossly misinformed (some of what you say was true about a decade ago, but hasn't been since around the 1.5 release in ~'04) or purposefully sp

It's different, because I'm saying that much system level work has to optimize by not using a garbage collector . I've literally implemented off-heap malloc()/free() in Java because GC is so untenable. I argue that makes a language with ha
