My trusty old #odroidc1. Have to retire the board though. Linux 3.10 is simply to old for any of the future topics I'm interested in.
He has been running #pihole for the last 5 to 6 years with only 2 sdhc cards. I changed the card just as a preventative measure halfway through. So, pretty solid performance.
Another blast from the past. The keyboard of my CPM system, so heavy you could do serious damage with it. Each key base contains a magnetically operated Reed switch, while the magnets were sitting in the moving part. The Z80 SBC with SIO, PIO and 2k EEPROM running the show. Keyboard matrix completely re-wired to fit existing scheme. The function keys were specially configured to produce Wordstar text processor sequences. Data via serial RS232 line.
I bought this hot sauce from YouTuber ChilliChump beginning of this year. Today was the time to check it out. Wow, what a burner. I nearly reached my limit of hotness and it has only 11/2 points on ChilliChump's hotness scale (I have another sauce with 3 points, which will probably get me a heart attack). But it tasted so good, that I had to add more to my chicken breast piece multiple times.
I'm immensely frustrated at the moment with #emacs and #lsp in particular in the context of Golang. After picking up an apparently flakey version of lsp-mode from Melpa, each file save took more than 15s. Tried VSCode yesterday afternoon, which worked fine in principle, however habits and muscle memory got in the way. So I somehow managed to reinstall a lsp-mode from GitHub release page, which appears to fix things.
And the new Pi-Hole 5 doing it's job.
All marked request are coming from the same Android tablet in the house hold, primarily used to mobile gaming. I've whitelisted some of the addresses at the moment to see whether that reduces the sheer amount of requests from that one tablet.
The last Pi-Hole 4 requests ...
A dashboard snapshot of my Odroid C1 running pihole 4. I actually switched to pihole 5 on my Odroid C2 about a week ago (incl router reconfig). The Synology was still using the old pihole not having been rebooted. Mildly interesting, the last lone request coming from the new pihole server from NodeJS actually running NodeRed for the daily sunrise email.
The resurgence of vinyl continues...
Check out Giuseppe Ottaviani's active live stream at https://www.youtube.com/watch?v=GLWdA3440qU if you're into Trance. Practically every DJ/Producer I'm more or less closely following has either produced exclusive vinyl sets or is including vinyl during these times.
I'm completely baffled, how those pickup systems with their tiny stylus swinging in the groove can survive those back and forth moves of the disc.
Recently I came by this article on HN: https://www.jeffgeerling.com/blog/2020/im-booting-my-raspberry-pi-4-usb-ssd
Nothing wrong with it or to criticize. It's of course easier and much more streamlined to be able to boot from the board bootloader directly to OS (without SD card), but with the kernel argument root= you basically could do this since forever(?): separating kernel (and initramfs) coming from µSDHC and running the rootFS on an actual harddrive or SSD. Running my owncloud/nextcloud from HD since a couple of years.
Well, I've been using the Linux "ip" command as the successor of "ipconfig" now for about 4-5 years. Never having read the manual page ever, only living by the online help of the command. The recent issue of the German computer magzine highlighted the usage of the "ip", many usages known to me. There were some gems in between however. Checkout the options (long form) '-color', '-brief', '-human' and '-json' (in combo with '-pretty) in the manual page.

As I guess an appetizer in my order of the CC2531 they included this little beauty, a capacitive touch switch. This is really useful for potentially many Arduino/ESP8266 projects. Often better suited than a mechanical switch.
Here's a link from some random seller.
The Odroid C2 runs InfluxDB, MQTT, Node-Red and Pihole 5/Unbound in the future.
The Rock64 runs Wireguard VPN, Caddy, PostgresSQL, Nextcloud and TT-RSS.
And there is a Odroid C1 currently running Pihole 4 with local hack (3.10 kernel too
old for newer Pihole) and Unbound DNS resolver.Mut aufbringen (2/2).
This morning I gathered the courage, to update the mainline kernels of my Odroid C2
and the Rock64 to 5.6.15, previously running 5.3.11 on Arm Arch Linux. On Arm this
always a touch more dicey than on X86. First there is no LTS kernel unless you are
using a distro with the original vendor supplied kernel version, which are somewhat old
and second, if there is problem you're in for a µSDHC swapping orgy between the Arm
board and your host system. Fortunately everything was smooth sailing. (1/2)
Posting some pictures in the coming days from old computer tech I build roughly 35 years ago when 6502 and Z80 were the hotness (and to a lesser degree 8080, 8085 and 6800).
The core of my CPM 2.2 system. Z80 CPU, 64k memory, 4k EEPROM containing boot code and CPM BIOS moved into bank switched additional memory on a different card. Nominally running at 4MHz, however ran with 5MHz. Everything hand wired and soldered.

Primary focus is in IPv6, but also works for IPv4. You can even use
your own domain, if you have a currently unused one.
Works like a charm. With any AVM Fritzbox in particular. Config is a
simple cut/paste job. One building block for your home cloud storage.
Not my own discovery, but from the German computer magazin c't.
