JA: I didn't really know what thread safety was in Java, so I wrote a little Java Swing thing and of a Java friend I asked: I wrote this Java process and it worked fine. I could create one window, and then I created 2 windows in a graphical program and I drew a rectangle in one and I drew a rectancle in the other and it crashed. And I said "Why did it crash?" And he said "Well the Swing library's not threadsafe". Now, what does that mean? It means if you got one thing that works, you do 2 of them in parallel, they interact in strange ways. I thought "How can you program like that? It's impossible to program!"
Давно хочу изучить Эрланг, кстати. Кажется, эта беседа убедила меня заняться этим в ближайшие месяц-два.
