A colleague got stuck trying to parse a 1-million-lines CSV for a while, then he found out that the last line was a PHPMyAdmin timeout error. Maybe they should add "All CSV contain no error messages" to the list :)

Hah, same in my household but with Age of Empires II and Caesar 3. Strategy games are particularly fun/engaging when played cooperatively as a single player.

I'm constantly amazed at how little effort Twitter put into UX. Many of the features were only adopted after 3rd parties made them popular (RTs, pictures) or because people found ways to circumvent the platform's limitations (Peop

On the other hand, software often follows the Pareto principle: 80% of the time is spent executing 20% of the code [^1]. Optimizing/migrating just that 20% would yield most of the benefits of a complete rewrite. (Good luck if that 20%

Just my two cents, but BEAM has some nice features when it comes to distributed systems. You can basically exchange messages with any other process, provided that you know where it runs. If you have the right permissions, you can even spawn

Using exceptions is totally common, but this seems to raise/catch/log 6 errors each time it tries to parse a `for` statement. I'm a noob when it comes to compilers, but maybe a token -> function dictionary would be a bette

I don't find it "premature" optimization at all. IMHO it is barely "optimization" if you're just using the right tool for the job (namely a hash table instead of a list when you need key-value lookup).

And about optimizing compilers, neural networks, and static program analysis four decades ago. Computer science is a fast-moving field, sure. But not all of today's research bring tangible results by the end of the week, and we should

I mean, probably many elementary code smells (e.g. those related to null references) just pop up over and over again in a sufficiently large code base, so an AI could reasonably be trained detect them and thus prevent some of the bugs that

Yes, this puzzles me too. Maybe the fact that you can redefine both the methods of `foo` and the function `Foo` at any time? And you can also change `foo.prototype`, I guess?

May I chime in? A gentle introduction to process algebras [^1] shows some examples of how you can represent programs as (possibly infinite) state machines. Essentially you define some operators to compose smaller programs (aka. processes
