   @jakob There are definitely languages that *should* only be used for trivial tasks. But then you give them to humans and you get web application servers written in awk.

     But even if one accepts the premise that apart from guix-daemon guix is just a big DSL or whatever, and maybe that wouldn't count, there are components of the implementation of that DSL that are worthy of being called complete apps on their own, like the cpio implementation.

     @clacke @dthompson @jakob @moonman Guix does have a lot of DSL, but also a ton of functionality written in that same language that isn't just package definitions... vm support, environment stuff, etc. There's 50k lines of scheme in the "guix" subdirectory, none of which is package definitions.

     @cwebber @clacke @jakob @moonman I have a Linux container implementation in there, for example. Lots of useful libraries in Guix.

   @ninjawedding @verius @maiyannah Reminds me a bit of how !tcl chooses different in-memory representations of an object depending on how you use it.

     "Array Layouts for Comparison-Based Searching": https://arxiv.org/pdf/1509.05053.pdf
     
     One thing that I've had to repeatedly struggle with in gamedev is the importance of keeping the CPU fed with data. This usually means predictable memory access patterns and contiguous data structure layouts.
     
     Unfortunately some very useful data structures -- maps, for instance -- are usually implemented in a way that are non-contiguous and don't have predictable access patterns. What do? Well, the easiest (and often quite sufficient) way is to maintain a array of (key, value) tuples, sorted on key, and binary-search it. There are other methods, though, and this paper is a neat survey of those methods.
     
     Bonus: Section 2, "Processor Architecture Considerations", seems to me to be a pretty good overview of just how badly memory latency will slow your code down and the methods employed by CPUs to overcome that latency.

     @ninjawedding @maiyannah http://wiki.c2.com/?AlternateHardAndSoftLayers is a time-honored tradition.
     
     I haven't played with Lua, but it I were to use Lua and interface with C libraries, I would have a look at http://terralang.org/ , which looks very interesting.
     
     I have to say though that Python's ctypes, which supposedly were inspired by Lua's C integration, work surprisingly well, at least for simple things. For the less-simple things, we have written a Dwarf parser at work, which can dynamically create the types by introspecting the debug data of the C code.

   Consider it an untested work in progress. It's !TclTK, and meant to repair the database entries after an instance moves from HTTP to HTTPS. Use at your own (and your instance's users') risk.

     Do they use system fonts? I know !TclTk supports #Unicode at the script level, but I'm not sure about the GUI. Squeak !Smalltalk 3.8+ also supports Unicode.

   Next up:  functions, classes, files, and tests (so happy this book includes unit testing!).  I'll probably work through the sample projects to get my head around some idiomatic Python 3 as well.
   
   Python 3 reminds me of my halcyon days with Perl so many years ago.  Ruby never gave me this kind of vibe.  Ruby always felt more expedient.  Common Lisp always made me feel erudite.  I just need to get things done these days and I like to have some insight on what's happening under the hood.

     @hobbsc I don't do much with it, but I must admit !Python 3 feels very natural, like speaking US English does. It's tied with !TclTk for my favorite lang.

    Hmm. #Eagle is an implementation of the #Tcl scripting language for the Common Language Runtime (CLR). It is written completely in C#. https://sourceforge.net/projects/eagle/ !TclTk for dotNet
    
    It seems to be currently maintained, as opposed to #TclSharp https://sourceforge.net/projects/tclcsharp which seems to have ended over a decade ago.

    Discovering a few things I do not like about this #Mageia 5 install. Latest is that using tclsh interactively crashes with "alloc: invalid block: 0xa027f0: b8 f4" ... but I can use tkcon http://tkcon.sourceforge.net/ without issue. !tcltk
    
    I'm hoping that Mageia 6, whenever it releases, will fix this and other issues without bringing too many of its own.
