Many things can lead to it: accidental wipe/format of the boot partition accidental dd to a wrong drive (sure, you pressed ^C right away but your grub is gone, sorry) exceedingly “smart” utilities overwriting MBR or re-initializing encrypted partitions drive/memory failures (power outage, random bit flip, etc.) There are plenty of manuals on how to restore an accidentally wiped boot partition.https://nagimov.me/post/running-docker-on-32-bit-hosts/Sun, 03 Feb 2019 00:42:28 -0800https://nagimov.me/post/running-docker-on-32-bit-hosts/Docker is known to not to support 32-bit hosts. As per debian installation instructions: Docker CE is supported on x86_64 (or amd64), armhf, and arm64 architectures. 32-bit hosts are unlikely to become supported either – “let’s bring docker on 32-bit” issue was closed and locked back in 2014. Nothing fundamentally prevents docker (including latest version of docker CE) from running on 32-bit platforms. I am currently running a slightly outdated version 18.https://nagimov.me/post/alsa-utils-arecord-bug-lots-of-.wav-files-ignoring-duration-parameter/Thu, 18 Aug 2016 20:56:00 -0800https://nagimov.me/post/alsa-utils-arecord-bug-lots-of-.wav-files-ignoring-duration-parameter/I ran into a rather funny bug recently – when recording audio on an RPi with Raspbian Jessie via an external USB sound card, arecord doesn’t stop recording after a period of time specified by --duration flag, but keeps running and filling files *-01.wav, *-02.wav, etc. with garbage data. Googling doesn’t return a solution, except an obvious one to killall -KILL arecord. USB microphones are also affected. Since I have another RPi running Wheezy and showing no symptoms of the bug (and being free of systemd malware ;), the bug is likely in arecord itself.
