  • The basic software like the Intellij Community Edition is also fully open source. (And it’s not actually basic at all. It’s a great full featured IDE)

    Basically you’re only paying for their support/updates and for specific language and toolkit support, which makes sense to me. They need to pay their staff somehow.

    It’s not comparable to Adobe or other crappy manufacturers where you own nothing.






  • You acquire skills and then start the business. Without skills, you won’t know if the idea is any good.

    Like your idea could be to create and sell a software to design Lego builds, but without any skills in software development or law, you’d have no idea if that’s feasible programming wise, how much work it would be, or if Lego might sue you for trademark violation if you do that.

    Ideas are easy, doing the stuff is hard.

    Obviously you can outsource some parts, for example you could hire a lawyer to make sure you violate no trademark law, but when you don’t have much money, the reality is that you will start small and have to do most research and actual work (if not all) yourself.



  • The main difference is that when you compile a program for Windows, Linux etc., you have an operating system and kernel with their exposed functions/interfaces so even in a compiled program it’s pretty easy to find the function calls for opening a file, moving a window, etc. (as long as the developer doesn’t add specific steps hiding these calls). But in an embedded system, it’s one large mess without any interfaces apart from those directly on the hardware level.


  • How often does branchless programming actually matter in the day to day life of an average developer?

    Barely never. When writing some code that really has to be high performance (i.e. where you know it slows down your program), it can help to think about if there are branches or jumps that you can potentially simplify or eliminate.

    Of course some things are often branchless, for example GPU shaders, which need very high performance and which usually always do the same things. But that’s an exception.
