I had vaguely heard of Flipper Devices. I am a sucker for minimalist open tech in every form. Their new project #FlipperOne is an audacious plan and I will be fascinated to follow along.

After 5 years or suffering I found out how to make Linux not grind to screeching halt every time a write is being performed to Raspberry Pi SD card:

Put
#!/bin/bash
echo 128 > /sys/block/mmcblk0/queue/max_sectors_kb
echo bfq > /sys/block/mmcblk0/queue/scheduler

into /usr/local/bin/set_scheds.sh . Put

[Unit]
Description=Set Schedulers
After=sysinit.target
[Service]
Type=oneshot
ExecStart=/usr/local/bin/set_scheds.sh
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target

into /etc/systemd/system/set_scheds.service . Do:
chmod a+x /usr/local/bin/set_scheds.sh
sudo systemctl daemon-reload
sudo systemctl enable set_scheds.service
sudo systemctl start set_scheds.service

I asked a friend full time employed as Linux kernel developer. He didn't know. He didn't know the max_sectors_kb is actually a parameter of the I/O scheduler. I discovered it accidentally. The doc is bad.

IMO horrible UX.

To prevent systemd from destroying your Raspberry Pi SD card by constant 100% writing saturation of coredumps despite these being disabled, just because some Glycin HEIC thumbnailer is constantly segfaulting while you are browsing smartphone pictures, do:

Put Storage=none and ProcessSizeMax=0 into /etc/systemd/coredump.conf and do systemctl daemon-reload, delete contents of /var/lib/systemd/coredump

sudo systemctl mask systemd-coredump.socket

sudo systemctl stop systemd-coredump.socket

Is the universe telling us something when a server goes missing but leaves behind two of the saddest cables ever seen in a 'professional' environment? What else is hiding in plain sight?

Where you expect a high-power server, you get... two forlorn cables dangling in open space. Who knew IT could be so suspenseful?

Picking up a Raspberry Pi Zero to drive an old small monitor for a #homeAssistant dashboard in my workshop.

Hmm, I can prob run VLC on it and have my audio chimes playing down there too rather than just in the kitchen (via the awkward VLC over telnet integration).

#lazyweb #lazymastodon. Find me an orderable part number for digikey/mouser/mcmaster for the solderable nut used on the #raspberrypi CM5 IO Board?

The "CM5IOBOM.txt" included is not very helpful.
