  • 01:55, 20 March 2024TRIM (hist | edit) ‎[1,112 bytes]Dank (talk | contribs) (Created page with "SSDs generally need to have the blocks belonging to a file explicitly deallocated. This is done with the ATA TRIM command. Unfortunately, regular use of TRIM can have negative effects on performance (TRIM cannot be queued on some devices) and lifetime. It is thus not generally recommended to trim after every delete operation, though this can be configured ("online mode"). Note that trimming generally requires the filesystem to be mounted, unlike e.g. <tt>fsck</tt>. Note...")
  • 06:10, 8 March 2024Rescuing Linux (hist | edit) ‎[7,958 bytes]Dank (talk | contribs) (Created page with "Sometimes you need perform irregular, unpleasant tasks involving a Linux box. One generally picks up the techniques via experience. This kind of thing tends to become less necessary as one learns Linux better, and thus it's easy to lose currency. The introduction of systemd, for instance, changed almost all of this shit up. ==grub== ==access sans password== ==kernel command line== ==initramfs== Almost all distributions ship kernels making use of initramfs these d...")

The latter was delightful, the former less so. My summary of io_uring through liburing 2.3 hit #1 on HackerNews (twice!) and the great [https://lwn.net LWN], which pleased me. Work on these technologies has progressed, and it seems time for an update. ==XDP== One of the big problems I had with <tt>AF_XDP</tt> sockets was the lack of support for large packets. One could typically only...")
  • 08:50, 11 February 2024Ebooks are hot garbage (hist | edit) ‎[5,128 bytes]Dank (talk | contribs) (Created page with "'''dankblog! 2024-02-11, 0349 EST, at the danktower''' Pretty much exactly what the title says. I did not consider ebooks when writing <i>[https://midnightssimulacra midnight's simulacra]</i>. This was both fortunate and unfortunate: unfortunate because it's proven difficult to make an acceptable ebook after the fact, fortunate because I really like the print version, and it's more important to me than the ebook, and properly designing for an...")

The speakers are awesome, but getting them working well with Linux was not completely trivial, and is not quite complete. At the time, I had the following versions of crap: * Linux 6.7 * Pipewire 1.0.1 * Pulseaudio 16.1 * KEF firmware 2.0 ==Requirements== I was using MPD 0.23.14 for my music, but I needed a solution at the audio device level, so that...")
