    @derSammler those are good examples of Ball Grid Array and Land Grid Array, e.g. BGA and LGA cores. The BGA page has examples of many sub-types, and links to the other primary designs, kinda worth a look:https://en.wikipedia.org/wiki/Ball_grid_arrayThere's so much fun to be had with old CPU collections, especially vintage alternate types like the Alpha. Sun UltraSparc and PowerPC from the same era also have some beautiful examples. That DS15 CPU is a classic (https://en.m.wikipedia.org/wiki/Alpha_21264), very interesting early example of using branch prediction calculations to accelerate cache reads vs suffering potential cycle penalties and stack eviction.> The predictor was used as the Alpha 21264 has a minimum branch misprediction penalty of seven cycles. Due to the instruction cache's two cycle latency and the instruction queues, the average branch misprediction penalty is 11 cycles. The algorithm maintains two history tables, Local and Global...> The local predictor consists of a 1,024-entry by 10-bit branch history table... Each entry is a 3-bit saturating counter. The value of the counter determines whether the current branch is taken or not taken.> The global predictor is a single-level, 4096-entry branch history table. Each entry is a 2-bit saturating counter; the value of this counter determines whether the current branch is taken or not taken.ok ok, enough of this nerdery. there are Alpha 21264 CPUs on eBay if anyone wants to own a piece of this wonderful engineering. https://ebay.us/m/ttryzO

    Sorry for double-posting:

    I hadn't made any changes since my last post, but posts are coming in as normal now and I am still on the develop commit.
    Very temperamental lol. Now to monitor it and see if I see any fairy.id posts.

    Are there implementors of web+ap? I'd be interested in adopting.

    I assume the fallback behaviour is to just assume https?

    web+ap, which was proposed by Fedilink authors. To my knowledge, it is the most widely adopted proposal

    julian After playing around with the different branches over the last day or so, It seems that new posts are not coming in from relays.
    'Remote Categories' and followed profiles are working fine.

    I reverted to the main v4.5.1 release and after an hour or so, posts started to come in, but not as many.
    So before I went to bed, I switched it back to the develop branch. As of this morning, there are no new posts from relays.

    I was able to get some logs.
    I have seen the 'Unable to acquire lock, skipping processing of ' before and ignored it since it posts were coming in.

    @pfefferle das habe ich schon versucht und gesucht und gesucht – nix passendes dazu gefunden. Aber wenn das dort sein soll … suche ich mal weiter.
