    Hutterer: The difference between uinput and evdev
    On his blog, Peter Hutterer answers an oft-asked question:
    "A recurring question I encounter is the question whether uinput or evdev should be the approach [to] implement some feature the user cares about. This question is unfortunately wrongly framed as uinput and evdev have no real overlap and work independent of each other. This post outlines what the differences are. Note that "evdev" here refers to the kernel API, not to the X.Org evdev driver.

    First, the easy flowchart: do you have to create a new virtual device that has a set of specific capabilities? Use uinput. Do you have to read and handle events from an existing device? Use evdev. Do you have to create a device and read events from that device? You (probably) need two processes, one doing the uinput bit, one doing the evdev bit.    "

    Klumpp: Adventures in D programming

    At his blog, Matthias Klumpp reflects on his experience writing the asgen tool for AppStream metadata generation using, of all things, the D programming language. "I started to implement the same examples in D just for fun, as I didn’t plan to use D (I was aiming at Go back then), but the language looked interesting. The D language had the huge advantage of being very familiar to me as a C/C++ programmer, while also having a rich standard library, which included great stuff like std.concurrency.Generator, std.parallelism, etc." What follows is a "huge braindump of things" Klumpp found enjoyable, including built-in unit-test support, safe functions, scope blocks, and documentation generation. After that, however, comes Klumpp's list of complaints—starting with the proprietary reference compiler and the not-quite-complete free-software compilers.
