Sorry to all the people who followed me but only see anime shitposts and bad jokes instead, and for being the top Fedi tag poster but not even 10% as cool as <any anime profile picture techie in Fedi>...

@chr @nightpool Hi, I have encountered a technical problem when trying to create an archive at When I click the "Request Your Archive" button, a "Compiling your archive..." entry appears, but after ~1 hour or so it just disappears again. :blobcatthinking2: I started seeing this problem since at least months ago. Could you please take a look? Thanks.

There's a stale entry in my archive list that started its creation since "Feb 22, 2022, 14:50" and now it still says "Compiling your archive...", I wonder if it's related to the current problem... Alternatively, the system claims "You can request an archive every 7 days." so I wonder if it's just a rate-limit thing that will automatically resolve if I don't retry within 7 days...

@chjara Back in the Usenet era, the entire history of all NNTP servers can be archived and replayed later, using just a mbox file. You can still read threads from the late 80s as if it was unfolding in real time. Fedi needs something like this.

The privacy situation is entirely different, though. Most Fedi users will probably reject any large-scale, server-wide archives. But I think some preservation can still be done at a smaller scale, for example, archiving posts in one's own timeline or single-user instance for personal use.

All those posts will be lost in time, like tears in rain.

the mastodon instance at is retiring 

for a lot of reasons, both personal and practical, i don't think i can effectively run a public mastodon instance any more, and i need to retire i want to do this responsibly and make sure everyone has a chance to migrate and export properly, so here is the plan for the instance retirement (feel free to share this link around):

due to ongoing moderation load issues and understaffing, between now and 1 november, the instance may be undermoderated. for other instances, if this poses an issue for you, i encourage you to use federation tools at your discretion. i would only ask that you be clear and public about your decisions so that users can figure out where they will be able to migrate their accounts.

thank you

RIP, end of an era... I'm one of the few Fedi users who have never changed instances, but it's time to move on...


Q: Why are the middle ages also called the dark ages?

A: Because there were so many knights.

Q: What do you call a bomb that explodes instantaneously?

A: Atomic bomb.

Another unbelievable circuit hack: abusing an ordinary DC-DC power chip to achieve microamp-level quiescent current, an application the chip was never designed for. The chip's own control loop is bypassed entirely, the feedback pin is disconnected. Instead, voltage regulation is done by turning the chip ON and OFF continuously via its CONTROL pin from an external opamp error amplifier.
