Had the idea to try Wireguard on the OpenPandora.

Building recent golang natively on the Pandora with its ancient toolchain options is not easy, but you can just check out the wireguard-go sources elsewhere and run
env GOOS=linux GOARCH=arm GOARM=5 make

(golang doesn't seem to have options for the old softfp ABI, so you get a binary with software floating point, but whatever.)

It executes on the Pandora and at least creates an interface, but I'm running out of time for an actual tunnel setup.

On the other up side, this Atari TT mainboard that was not exceedingly expensive on eBay seems to have basic functionality at least (I have another one that's dead), though the ribbon cables for the VME connector are missing. Can probably salvage those from the broken board though...

So, when you don't make exceedingly dumb errors (like me, see previous post), this works... I need longer wires on the TT power connector though, the current setup is kind of unwieldy: Atari TT mainboard powered by a PicoATX PSU, using an L7905CV to create -5V from the -12V line.

I guess the idea of "I don't need to know anything about electronics when I can just use an L7905 to create -5V from something else" kinda backfired? Though I'm not sure how (see text between quotes).

Checking the #FacebookLeak, some people in there doesn't even have a FB account. But it turns out they have a WhatsApp one. In the leaked data WhatsApp users' ID seem to start with 1000. It also includes gender, which is not something one declares when registering on WhatsApp. 1/2

Ah, dang. While I was at it, I tried to add a micro SD card to the LTE stick I'm using for a backup connection when DSL fails... But that doesn't seem to be supported by the system (though I think it just shows up as USB storage when connecting the device elsewhere). Ah well, not that important.
Wonder if I need to add an external antenna to the stick though, since I only get 2G connectivity. I mean it's ok to ssh in for debugging, but it makes my services at home relatively unusable otherwise.

Ok, so disabling quotas drops all existing qgroups.

Before:
# btrfs qgroup show /lxdstore/ | wc -l
1677
# btrfs quota disable /lxdstore

After:
# btrfs quota enable /lxdstore
# btrfs qgroup show /lxdstore | wc -l
WARNING: qgroup data inconsistent, rescan recommended
38
# btrfs quota disable /lxdstore

There's quite a bunch of qgroups that used to belong to deleted snapshots. The docs say that those don't get removed automatically with a snapshot.

From some posts I found it seems that all qgroups will be dropped when quota is disabled on a btrfs filesystem, but the documentation doesn't tell, so I'm not sure if I can just go on and send a btrfs quota disable, or if there's anything else I need to do to clean up things before doing that...?

After wondering why the btrfs-cleaner kernel task takes quite a chunk of CPU time on my lxd host today, it turns out that I unkowingly enabled btrfs quotas on the filesystem by setting a disk quota on one of the containers.

Now, btrfs quota / qgroups documentation is slightly spotty - so after removing the quota from the container configuration I'm not sure if I can just turn off quotas on the filesystem?

(I'm not interested in a discussion on the merits of using btrfs.)

I have re-entered the world of blogs, by looking at my RSS reader again. I performed spring cleaning of old feeds, and would be happy to receive suggestions for blogs on: a) game design, b) networking (protocols, etc), c) cryptography.

There are probably quite a few other suggestions I'd check out, so don't feel restricted to these.

Boosts appreciated!

Uh. I've been reading a book out in the sun for too long, and now the green in my terminal window looks decidedly orange (ok, it's fading to the correct colour already).

One of the things that suprisingly still works on a Mac OS X PPC Mac: Put a music CD into the drive, and iTunes 10 (2012) will happily query the Gracenote CD DB to retrieve a track list. Now that's an API that hasn't changed in ages, apparently.

Heh... Also I read that before actually installing the new version. The upgrade splash screen now looks like this:

(I kind of wonder about the blogspot URL date - the post heading sais "March 29, 2021" though, and I noticed the post just now when I went about updating the browser on my G4 iBook, which I usually do about every three months or so...?)

Development on the last browser that supported MacOS X PPC (TenFourFox) has stopped: "Writing and maintaining a browser engine is fricking hard and everything moves far too quickly for a single developer now. However, JavaScript is what probably killed TenFourFox quickest. [..] web browsers' primary role is no longer to view documents; it is to view applications that, by sheer coincidence, sometimes resemble documents."

It's a long goodbye text, but well worth reading: tenfourfox.blogspot.com/2020/0

Oh look, my old desktop PC still boots, after I removed the 512MB DDR RAM module that seems to be defective (started booting, then powered off when it was in there). Though the remaining 256MB seem tight even for Windows XP.

Lots of EVE Online screenshots from 2008 on there...

I think I'll just salvage the useful parts (there's a PCI SATA card with bootable BIOS, but I don't think I have any other boards left that can make use of an AGP graphics card)...
