  • There’s a model that id used for open sourcing their engines. The source code is open, but the assets (textures, models, sounds, etc.) are still copyrighted and you still have to buy the game to get them legally. This means the company still sells copies on Steam or wherever, and games that replace all the assets can still sell them without any licensing costs, too.

    I’m a little surprised this model never caught on. Even id only ever published the engine to the previous game–Quake 3 was open sourced a little after Doom 3 was released–and the practice seems to have stopped when John Carmack left.

    Possibly because nobody has tested it in court, or some other subtle legal issue?





  • If it’s compsci, then it doesn’t need to be bare metal. It should be a language that’s good at demonstrating abstractions. Java wouldn’t be my choice, here. Elixir would be a good one.

    You might want bare metal as a prereq to an operating system course.

    If it’s software engineering, OTOH, then yes, a bare metal language has a bigger place.




  • Libertarian Socialism has little to do with US libertarians. The term was openly stolen for the Right. The intellectual history is completely separate.

    Murray Rothbard: "One gratifying aspect of our rise to some prominence is that, for the first time in my memory, we, ‘our side,’ had captured a crucial word from the enemy . . . ‘Libertarians’ . . . had long been simply a polite word for left-wing anarchists, that is for anti-private property anarchists, either of the communist or syndicalist variety. But now we had taken it over… "


  • While it’s true that lots of libertarians prefer Linux, the first ancap I met in an online forum was a Romanian-born Christian living in the US, was so fundamentalist that he was actively looking for a church where men and women sat on different sides of the pews, loved Microsoft, and hated Linux. He also had a habit of changing the definition of words in the middle of debates. People found him completely infuriating.







  • We tend to forget about it these days, but the Unix permissions model was criticized for decades for being overly simplistic. One user having absolute authority, with limited ways to delegate specific authority to other users, is not a good model for multi-user operating systems. At least not in environments with more than a few users.

    A well-configured sudo or SELinux can overcome this, which is one reason we don’t bring it up much anymore. We also changed the whole model, where most people have individual PCs, and developers are often in their own little VM environment on a larger server.
