please excuse me for one curmudgeon vaguepost: if you don't hotplug it into a backplane that provides (at least) power and networking, it's not a blade, even if you make a custom enclosure a bunch of them fit in

researching parts for a ridiculous project, thought I'd have to use the aluminum case as a heatsink and underclock, but sunon makes an 8mm fan, look at these things

it pains me big time to say this, but having one entire linux computer per display is probably the cheapest way to do a bunch of network attached image/video; an allwinner chip is like $5

there are some neat uboot commands not listed in the documentation, like all the things you can do with FDTs at runtime (splice in precompiled fragments, change values, delete nodes, create new nodes)

it's popularly claimed that itanium failed because compilers weren't good enough; has anyone ever done benchmarking with compilers from 2001 vs ~2024? I can't find a way to access various versions of icc without paying up...

weird misfeature of the prusa core one (which I'm generally happy with): you can't manually set the clock, you have to let it hit their NTP server

my "no new computers unless they fit on the rack" rule permits this one: an OSA 5401, a PTP clock with GPS and an OCXO, all in the form factor of an SFP module

cute pattern for indenting a string with printf, paraphrased from some code I saw in u-boot: make a constant string with a bunch of tabs, index backwards from the end of it
![static char tabs[MAX_LEVEL+1] = "\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t"
"\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t";
printf("%s%s\n", &tabs[MAX_LEVEL - level], pathp);](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:bv5mxqc5ydauo6oifeacskzv/bafkreiff7jierfhn2epbrmi4jkz2oq4ftr2oecxsjyv3qe6b7s3mxcdejq@jpeg)
