Builder GTK 4 Porting, Part V

Small changes here and there for template-glib to cover more cases for us in our keybindings effort. Improved type comparisons, fixed some embarrassing bugs, improved both GObject Introspection and GType method resolution. Had some interesting talks with Benjamin about expression language needs within GTK and what things I’ve learned from Template-GLib that could be extracted/rewritten with a particular focus on continuously-evaluating-expressions.

  • Steinar H. Gunderson - Speeding up Samba AD

    One Weird Trick(TM) for speeding up a slow Samba Active Directory domain controller is seemingly to leave and rejoin the domain. (If you don't have another domain controller, you'll need to join one in temporarily.) Seemingly, not only can you switch to LMDB (which has two fsyncs instead of eight on commit—which matters a lot, especially on non-SSDs, as the Kerberos authentication path has a blocking write to update account statistics), but you also get to regenerate the database, giving you the advantage of any new indexes since last upgrade.

  • How to Change File Extensions on Linux

    File extensions help both operating systems and users distinguish between different file formats and understand the contents stored inside them. When you see a file with the ".txt" extension, you instantly know it contains text data. Similarly, ".exe" file is a Windows executable and ".sh" files are Linux shell scripts. But what if you want to change these extensions for some reason? Perhaps you need to rename a text file to a Bash script. Simply writing the code in a text file won't do the job. On Linux, changing file extensions is much easier than you might think.
