Deutsche Post and DHL switch to OSM from Google Maps [DE]
  • since commercial usage is not free

    Commercial usage oft the osm data is free, see the OSM license. The article even speculates that they switched from Google maps due to licenses costs.

    Of course this doesn't apply to commercial services that provide e.g. map tiles.

  • Whats your thoughts on Ai in your terminal?
  • So compared to plain bash without autocomplete and Ctrl+R it may be useful. It is probably a step back for everyone else.

    I think it could be much worse than even a plain shell with ^R, as the llm will be slower than the normal history search and probably has less context than the $HISTFILE.

  • What are some of the best optimizations you applied to your code?
  • I recently spent some time optimizing a small Julia program I wrote that generates a lookup table of brainfuck constants. Because it only needs to run once, I originally didn't care about performance when I originally wrote it (and the optimization was mostly for fun).

    I achieved an ~100x improvement by adding types, using static arrays and memoization. In the end, the performance was mostly limited by primitive math operations, I tried using multiple threads, but any synchronization destroyed the performance.

    However, the most impressive thing was the ability of Julia to scale from dynamically typed scripting language to almost a compiled language with minimal changes to the code.

  • Very clever...
  • Having the commands listed at the bottom by default is one thing i personally dislike about nano, because they take up space while being useless to someone knowing the commands (or at least knowing how to open the help in, which is what you can do in vim to achieve the cheat sheet). The alternative that vim uses, is to show the commands when starting the editor without opening a file.

  • *Permanently Deleted*
  • I don't really have a single favorite a language, if I am able to choose freely it depends on the task.

    • C++ for natively compiled programs and C interoperability, I like the types from the STL and templates.
    • Clojure is IMO great for data-oriented programs, I really like the immutability and it being a lisp. The java interop and the ability to compile to JavaScript with clojurescript can also be useful.
    • Julia for smaller (mostly numerical) programs that should be fast at runtime. The type system is great in being optional, but strong and significantly improving performance when types annotations are used.
    • Fennel (or Lua) is definitely my favorite Language for embedding into larger programs and scripting. Fennel has the advantage of being a lisp and cleanly compiling to lua.
    • brainf*ck is great as a simple language to have fun and enjoy programming
  • Programming for kids
  • I genuinely don't know if scratch is the right choice or a simple text based language would be better, especially for the older kids. Just from my personal experience, I started programming in BASIC at 12 and don't think I would have had as much fun and continued programming if i had used scratch instead.

  • I Think Ubuntu 23.10 is Making a Mistake…
  • You don't even need to look at the extension to identify most file formats, as there are unique magic numbers stored at the beginning of most (binary) formats. Only when a single binary format is reused to appear as two different formats to the user, e.g. zip and cbz are extensions relevant. This is how the file command and most (?) Linux file explorers identify files, and why file extensions are traditionally largely irrelevant on Linux/Unix.

    This means your idea of suggesting software based on the file type is even more practicable than you described.
