To paraphrase Knuth, "programming is explaining to another human being what you want a computer to do." Should you take it to the extreme Knuth did with Literate Programming? I personally don't. But, once I've successful

I've been using Nunjucks client side and Flask + Jinja2 server side for about a year now. While there's some duplicate effort, it's not as bad as you might imagine. The duplicate effort: porting some custom Jinja2 filters and

What an interesting experiment. Could there be some basis, after all, to the urban legend that eating carrots improves night vision? Carotenes are "partly metabolized into Vitamin A" [1], but this experiment is skipping the precur

Granted, the object-orientation [in Perl] felt more like a hack than a normal language feature (because it was one)... Perl's OOP is definitely a hack! But it's a clever and elegant hack, and younger languages can learn a lot f

I understand the problem scenario with ext3/ext4 journalling you're referring to here and below. However, HN runs on FreeBSD, and my understanding is that the combination of soft-updates + journalling there actually do provide a

So, "collect it all" ... unless you're in court, in which case it's okay to delete key evidence because it's "hard" to keep evidence? Snark aside, this part made me curious: the NSA may have to shut down

> JavaScript was, as far as I can tell, arguably the first truly mainstream language to embrace first-class functions and closures. This is a nitpick, but Perl has had closures since the early 90s -- before Perl5 even.

It sounds like the cost of context switching between these very different workloads (crypto, disk I/O, network I/O, protocol buffer parsing and formatting) could be improved in Twisted. Any idea where the overhead comes from? Twis
