Schritt für Schritt: (Urlaubs)foto-Backup mit Raspberry Pi und Syncthing
Hello, I’m a #newbiehere and I’m posting because I’d like to share something.
As an old IT guy, I want to share a script that makes life easier for (home) admins when a “curl” or “wget” fails during certificate (#SSL / #TLS) verification.
This doesn’t happen very often, so I always forgot what to do, when it did happen.
The script checks which certificates are missing and downloads them, so you can add them to your list of CAs (certification authorities) if needed. How to do this is explained in my accompanying documentation.
Maybe just take a look and see if it’s useful to you.
Of course it’s #opensource, described at https://github.com/himbeer-toni/UserScripts/blob/main/fetch-missing-ca.md, where you’ll also find a download link.
I’d be glad if it helps someone!

Hallo ich bin #neuhier und melde mich, weil etwas teilen möchte.
Als alter ITler möchte ich ein Skript teilen, dass dem (Home-)Admin das Leben erleichert, wenn wieder mal ein "curl" oder "wget" bei der Verifizierung eines Zertifikats (#SSL / #TLS) scheitert.
Das kommt nicht so oft vor, deswegen hatte ich immer vergessen was zu tun ist, wenn es mal wieder so weit war.
Das Script prüft welche Zertifikate fehlen, lädt sie herunter, so dass man sie ggf. in die Liste der CAs (certification authorities) aufnehmen kann. Wie das geht, steht in meiner dazugehörigen Doku.
Vielleicht einfach mal sehen, ob ihr es brauchen könnt.
Natürlich #opensource, beschrieben auf https://github.com/himbeer-toni/UserScripts/blob/main/fetch-missing-ca.md, da wäre dann auch ein Downloadlink.
Würde mich freuen, wenn es jemandem hilft!

big update to my little software - it now supports almost all general operations on #raspberrypi meaning that its ready for you to use together with your favourite #LLM as a natural-language way of asking your #raspi for instance to install software or debug a problem:

Dear Fedi, what are acceptable #VNC clients on #Windows? Need non-nerds to connect to a #raspberry_pi on the local (untrusted) network.
Required:
* supports encryption
* supports different resolutions between server (_can_ be 4k) and client (_can_ be HiDPI) smoothly
Nice to have:
* scaling contents to prevent scrollbars
* built-in ssh tunnel
* no need register with a 3rd party
Pro feature:
* Clipboard paste works

Internet in a Box - Mandela's Library of Alexandria
Internet-in-a-Box “learning hotspots” are used in dozens of countries, to give everyone a chance, e.g. in remote mountain villages in India.
It works without internet — like a community fountain, but for the mind — wirelessly serving anyone nearby with a smartphone, tablet or laptop.
Now you too can put the internet in a box and customize it with the very best free content for your school, clinic or family!

Encouraging one of my children with some RasPi projects (and making circuits). He *wants* to learn how to code and make computery things - but putting the time in to do so alas... He wants to be able to do amazing things before learning the simplest... #raspberrypi #raspi
I have the #battybirdpi semi-permanently mounted on the roof of the van now, and am enjoying that it's picking up birds continuously. I ended up just mounting the microphone and running a long-ish USB cable to the #raspi inside.
I do still have to update the GPS coordinates manually, something to automate in the future.
While driving, it does correctly note that the main noise it hears is 'Engine'!

A question for the FediBrain:
I need to run a mobile FullHD handycam (indoors) for a school production.
I have the cam, and have successfully done wireless streaming to OBS via vdo.ninja using a laptop and a HDMI->USB dongle. But the laptop is not mobile enough, and batteries won't last??? (I need to stream for about an hour on a charge, to be safe).
I'm thinking a Pi5 with a chunky USB powerbank can do this?
Thoughts? Alternatives?
Viele von uns haben schon einmal ein Elektronikprojekt begonnen, das als provisorische Lösung gedacht war, aber dann doch länger im Einsatz blieb.
Ich verstehe nicht, was an #HomeAssistant "einsteigerfreundlich" sein soll. ...
Ich habe (vorerst) nur einen Reed-Kontakt am Gas-Zähler und einen Ultraschallsensor (JSN-SR04T) in der Regenwasser-Zisterne.
Beide kann ich problemlos mit #Arduino (und C++) und auch mit den #Raspi-GPIOs (und Python) auslesen.
Es macht mich wahnsinnig.
Der RasPi 4 läuft ziemlich warm und die Einrichtung (via #MQTT) ist alles andere als intuitiv. GPIOs direkt auslesen will es natürlich auch nicht. ...
Am liebsten soll ich mir wohl einen #ESP32 oder #ESP8266 ins WLAN hängen, aber die können keine 5V für den Ultraschallsensor. ...
Und wofür will HA Internet und dubiose "Assistenten", die mir Alexa und KI schmackhaft machen wollen.
Ich gehe jetzt mal 'ne runde löten zum Entspannen, und wenn mir nichts besseres einfällt, dann kommt #OpenHAB auf den RasPi. ...
Dear #homelab bubble,
as is normal I have a dozen different SBCs (Raspi1, Raspi2, Raspi4,...) as well as some other thin clients running in my home lab. As none of them is connected to a monitor, each of them has some kind of serial-to-USB cable attached (to a serial output or to the Raspi GPIO pins).
Of course, I am lazy, and moving the laptop I am working on and attaching the right cable is too much effort. So I thought about finding another solution. Not sure if there is one and if I can afford it. So I would be glad if there is any input or ideas or hints or experiences or recommendations. Thanks in advance!
Lately I've been doing more #SelfHosting again due to the current situation. Of course, I'm paying particular attention to power consumption and noise. After good experiences with the #ARM64 architecture, even with power-hungry applications such as Mastodon, I'm now using the smartphone technology for my homeservers, too.
There are #SBCs with more open hardware, but the #RaspberryPi is widely available, well documented, powerful and inexpensive. And it is available with up to 16 GB of RAM.
Anyone operating a server on the Internet must install #security updates quickly. However, many people forget to restart running software so that the new version runs instead of the old one. The #needrestart tool helps with this on Debian-based Linux systems, which unfortunately is usually not pre-installed.
On my Raspberry Pi 4, needrestart
always runs correctly (automatically after apt upgrade
). On my Raspberry Pi 5, however, I first had to create a configuration file as described by the main developer here:
https://github.com/liske/needrestart/blob/master/README.raspberry.md
Previously, the tool always claimed that a reboot was necessary because it thought an outdated Linux kernel was running.
Next, I want to activate #LUKS hard drive encryption on both raspis. Unfortunately, this is not as easy under #Raspbian or #RaspberryPiOS as on other Debian systems. If you have managed this: Please let me know how you did it!
In letzter Zeit mache ich aus gegebenem Anlass wieder mehr #SelfHosting. Natürlich achte ich dabei besonders auf den Stromverbrauch. Nach guten Erfahrungen mit der #ARM64-Architektur selbst bei leistungshungrigen Anwendungen wie Mastodon setze ich jetzt auch zuhause auf auf die aus Smartphones bekannte Technologie.
Es gibt zwar #SBCs mit offenerer Hardware, aber der #RaspberryPi ist überall erhältlich, gut dokumentiert, leistungsfähig und preiswert. Und es gibt ihn mit bis zu 16 GB RAM.
Wer einen Server am Internet betreibt, muss zügig #Sicherheitsupdates einspielen. Viele vergessen aber, laufende Software neuzustarten, damit die neue Version läuft statt der alten. Dabei hilft auf debianbasierten Linux-Systemen das Tool #needrestart, das leider meist nicht vorinstalliert ist.
Auf meinem Raspberry Pi 4 läuft needrestart
schon immer korrekt (automatisch nach apt upgrade
). Auf meinem Raspberry Pi 5 musste ich aber erst eine Konfigurationsdatei anlegen, wie es der Hauptentwickler hier beschreibt:
https://github.com/liske/needrestart/blob/master/README.raspberry.md
Bis dahin behauptete das Tool immer, dass ein reboot nötig sei, weil ein veralteter Linux-Kernel laufe.
Als nächstes will ich auf beiden Raspis die Festplattenverschlüsselung aktivieren. Das ist unter #Raspbian bzw. #RaspberryPiOS leider nicht so einfach wie auf anderen Debian-Systemen. Wenn ihr das geschafft habt: Schreibt gern eure Tipps!
I just run two (TWO) commands in my #RaspberryPi, and in 4 (FOUR) minutes I got the latest major version of the awesome @photoprism running smoothly, no issues. This is the result of wise and professional work that prioritizes stability and bug fixing over fancy breaking features. Move fast, break things Go slow, fix everything.
Thank you so much to all PhotoPrism contributors for all this! Long live self-hosted photo management software!
