    The software industry is rapidly converging on just three languages: Go, Rust, and JS. It would be smart to learn one of those really well, and have at least a working acquaintance with the other two.

    If you think you're on the project from hell, this will cheer you up: * 6M lines of obsolete flavour C++ * 50K classes * CORBA * 48hr build time * Average dev turnover 3 months * 35 managers for 25 developers * Fired if you arrive at 9.01am buff.ly/2FVPAiS

    A paper about a C compiler which produces executables containing only printable characters, and the paper itself is produced by the compiler, and therefore is executable, and also plays music when you run it, and this is the paper: cs.cmu.edu/~tom7/abc/pape… /by @tom7 /via @danluu

    JUNIOR DEV: I'll copy and paste this code. MID-LEVEL DEV: Let’s refactor. If we add more abstractions, we can get rid of all this duplicated code! SENIOR DEV: A little copying is better than a little dependency. Copy and paste it.

    They say that every controversial political opinion you post on Twitter costs you half your followers. Well, here we go, then: • Cancel Brexit • Impeach Trump • Black lives matter • Refugees are people too • Believe women • Tabs, not spaces
