In this day and age, you use PCs to develop games for C64. You're able to do stuff you couldn't before because now you have the capacity to precompute an compress a bunch of tables and such. And you use modern developer tools (assemblers, e

Oh, I've mixed up order of arguments to if. The refactoring problem could have been solved in a more practical way (though more difficult implementation-wise) by implicit versioning of symbol definitions. Plus, I find that stack effect decl

Having been a long-time user of HP series of calculators (HP48g, HP50g), postfix notation is not foreign to me. So I tried Factor, and gave up on it for several reasons. First, there were obligatory stack effect declarations on each word. W

I thought that classes+methods were meant to transform an object from one consistent state to another consistent state. So why is immutability suddenly a big deal? (I.e., if it's a big deal, may it be because encapsulation is lacking? IOW,

Wow, the list of modules has gotten very respectable since the first time I heard about Julia. I have one concern though: how well-tested are they? There's one really prominent contributor (John Myles White), who has written a rather large

There's Peter Gutmann's cryptlib, which also supports OpenPGP (among a huge number of other things). http://www.cs.auckland.ac.nz/~pgut001/cryptlib/ It's also has a dual license.

I have played with the idea of making a GPG applet for the JavaCard platform. It's rather easy (I have a half-done prototype somewhere that used to work with an old version of GnuPG), but the lack of market didn't make it worthwhile pursuin

Dude, YOU have no idea what you're talking about. I'm talking about C, the language, not what one particular implementation gives you. AFAIK, C11 doesn't have a 128-bit int type, so how do you get the full result of 64x64 bit multiply? How

This shows that C and C++ are getting more and more out of sync with modern CPUs. Outdated if you want. Modern CPUs have wide multiplies (32x32->64), wide divides (64/32->32), a whole bunch of useful arithmetic status flags, yet C

Does it support REPL for various interpreters? (emacs has ESS for R, SLIME for LISP, surely others.) I couldn't find anything about this in the docs (just quick browsing) and nothing was apparent in the menus after I've tried to install it.
