"All numbers are doubles" is not something that any self-respecting JIT will emit. All numbers must behave like doubles, but what actually happens is code is agressively type-specialized. So, integer math is emitted, and overflow of 31-bi

With tree-style tabs (a fantastic Firefox extension) opening large amounts of tabs becomes more common because you can manage different lines of thought, and everything else sort of collapses down. I commonly have about 100 tabs open.

No, my argument is that the point is moot. If a task_struct on linux does not trigger an address space switch it is a thread. While to the kernel they are (regrettably) the same entity, they still have relevant performance characteristics o

Processes and threads are both schedulable entities in linux, which is a bit muddled, but when we talk about processes, it still implies a separate address space. That's the whole point of distinguishing them. Of course the more sane model

I mean, yes, the biggest win of lisp over other languages is that the metalanguage is the language. That is what is special about lisp. That is, when defining a macro, you are simply treating the program itself as data . Since code and d

I do not believe you. Who? If you can't list their names, then it's pretty clear that Apple doesn't approve of their actions whatsoever. If you can, then Apple explicitly working to close security holes, not providing a sponsored jailbreak

There is a law of decreasing returns when it comes to "resources". That is to say, an engineer only makes so much, and throwing additional engineers at a single project only gains you so much, and the gains of each additional engineer are f

There's a few aspects to discuss here. Firstly, in 2006 (5 years ago), x64 chips were Core2Duos clocked at about 2.2Ghz. This is top of the line, but even a mid-level processor would be something like 1.6Ghz. A PC would probably have about

With regards to performance, keep in mind that there is simply a difference in processor performance. A mobile architecture browser is just not going to be as fast as a desktop based browser. There are additional optimizations that can be d

My understanding is that the kernel will be based on Android. Userland code will be rewritten basically entirely, to boot to a gecko-based UI.

Writing an OS kernel is a great experience. You will be a stronger programmer at the end. Another good resource is CMU's course on the subject: http://www.cs.cmu.edu/~410/

The point is that... the patch is already in the nightly builds, and thus will certainly make it into beta and release builds (even if it requires additional patches on top). So your objection to this being vaporware is simply ridiculou

If you translate your coffeescript to javascript serverside, then there is no overhead on Jaegermonkey or v8 (obviously). Although I doubt that any of the browsers will ever support it directly, porting coffeescript to run directly on top o

You can't, unfortunately. The point is to be cognizant of the fact that expressions will be evaluated for their effects more than once (maybe). So, don't put effectful things inside a macro expansion.

That's nothing to do with C as a language, but rather to do with relevant APIs, which can be difficult to read at times.

Do people really think C is some mysterious, inscrutable language? "To many programmers, this makes C scary and evil." Is this actually true for people? I find C code generally very easy and straightforward to understand; there's not any ma
