Fediverse Disaster Recovery
Faulty peripheral power supply killed my server a little over a day ago.
120 gigs of MySQL data just wouldn't come up - backup is far from recent. My fault. Most corrupted tables were of course in Friendica.
After much nail chewing everything now appears operational again with minimum(?) data loss.
In other words: can you all read me?

On one hand, security… on the other, it would highly mitigate the need for a recent backup.
Friendica currently says "Delivery to remote servers completed 18/18" (paraphrased from german) for this post so can I trust everything is a-okay?

Finished reading this one by now.
Snappy short review:
This ist one great alternate take on the Peter Pan / Neverland story and it sure as heck is not written for children at all. If you fancy mature/twisted stories that are relatable yet different where it counts this, book really is for you.
It's a bit like book one ("The Last Wish") of the Witcher series if that helps you to make a more informed reading decision.
In any case this was a relatively short but sweet read and quite entertaining and gripping. The final twist (if you can even call it one) was of course quite obvious all along but does not detract from reading enjoyment at all.
Rating: 5 out of 5 stars
If you download your Twitter archive it arrives wrapped as a static HTML page, which is not very useful for doing anything with, and worse: it requires the original account to be still active to do useful things like enlarge the images since they use t.co links.
So here's a Python script to convert a Twitter archive to markdown or other formats: github.com/timhutton/twitter-a…
Now you can archive your tweets in any way you want.
Tach, Leute! Hat zufällig jemand von euch eine günstige und für Anfänger geeignete E-Gitarre mitsamt Verstärker, die er nicht mehr benötigt?
K1 möchte ihre Skills erweitern und sich neben der Konzertgitarre mal in die E-Richtung vorarbeiten... Und so, wie sie mittlerweile spielt, würde ich das gerne auch unterstützen.
(Gerne auch boosten...)
Folding@Home
I'm sitting here baffled by the immense influx of new grid computing participants (apparantly there's been a "call to arms" by graphics card manufacturer Nvidia) with huge gaming pc power that managed to saturate all available work units of Folding@Home within a couple of days.
Now I'm seeing quite a few end users bemoan the lack of work units. Am I wrong to think that if Folding@Home were run off of BOINC there would be at least a chance end users would participate in other Projects?
Don't get me wrong, I greatly applaud the gamer community for getting done what 8 supercomputers could not in this timeframe. We really need this.
However, I'm very skeptical of Folding@Home's modus operandi here.

Mir geht's leidlich, nicht so ganz gut, will aber nicht drüber gross reden.
Und Du? Bist Du noch in Krems? s' war doch Krems, oder...
Ja, alles Liebe in diesen irren Zeiten.
Ich bin zwischenzeitlich nach St. Pölten gezogen und hab mich hier ganz gut eingelebt - Verbindung nach Wien der Arbeit wegen ist auch bombastisch besser als von Krems aus. Die Railjets sind schon sauschnell und komfortabel.
Somit nochmals gute Wünsche für Dich und Dein Leben!

Finding a place (or two when plotting a route) still goes outside to a Nominatim server at OSM but I'm hoping to host that one myself too so every bit of data stays on-site.

•Ironically, if I would have had more services running in docker I might not have experienced such a fundamental outage. Since docker services usually tend to spin up their exclusive database engine you kind of "roll the dice" as far as data corruption goes with each docker service individually. Thing is, I don't really believe in bleeding CPU computation cycles by running redundant database services. And since many of my services are already very long-serving they've been set up from source and all funneled towards a single, central and busy database server - thus, if that one experiences sudden outage (for instance power failure) all kinds of corruption and despair can arise.
Guess I should really look into a small UPS and automated shutdown. On top of better backup management of course! Always the backups.

•Why so much? A simple daily timer that runs mysqlcheck + mysqldump + a backup of that would be enough for most people. Using a solid OS (Debian) and a filesystem such as BTRFS, ZFS or XFS will also save you from power loss related corruption. Why do people go SO overkill with everything?
Keep it simple, less services, less processes, less overhead, pick well written software and script the rest. Everything works out way better if you don't overcomplicate things.

•Holy cow, 120 gigs in a database?
Also remember, you don't want a backup solution, you want a restoration solution
