after years of pursuing this guy/team, the government will catch it then it may proceed to free the guy like it happened with Alexander Vinnik. Who was released bythe US and returned to Russia in February 2025. Guy was exchanged for Marc Fogel, an schoolteacher. mind you. great swap right?

as the scale is logarithmic a 4 is more than a thousand times lighter, imperceptible almost

awesome explanation. never thought about the complexity of doing analog and having precision issues because it's not discrete anymore and repeatable

so how do you save data over the cable when it's needed?

A thought experiment of how would an ethical system would look like if it was developed by AI.

So what happens if an AI goes up to Sinai and comes back with its own idea of what's good and bad. A debate evolving day by day

his not yet is actually:

couldn't workaround Capt has and turnstile, gave him a really small timeframe so it got desperate because it was enough time to test hypothesis and traction

* BRIN indexes are great for append only with an incremental value (a 50MB instead of 100GB index in timeseries data in my case)

* If your disks are ssd and scsi in different volumes, adapt the random cost of io in the config to let the planner now

* if you have RAID controller and a Battery-Backed Write Cache (BBWC), you can disable Linux filesystem write barriers. removing excessive fsync from the mouth of the psql demigod in SoCaL ~linux 2015, Bruce Momjian IIRC

* monitor disk usage, in backups pipe to gz, never to disk

* counter-intuitevely modern hardware may have an io bottleneck and plenty of cpu, so try Filesystems like ZFS using Zstandard (zstd), for boost in your Transactions per second

* if possible, schema multitenancy instead of database multitenancy, instagram talked about this decades ago

* indexes index functions results too, precompute those fields and partial indexes help a lot

* BM25 and FTS in pg are so good you probably don't need Elasticsearch and you will save a lot in de-sync between both of them

* you may be hacked in this brave new world post Mythos, thus, learn PITR to an external only write, no override medium like S3

about the use of ANY, that's perfect for tracking changes on an audit table per field

yeah, I think what makes this post different was that AI did it. hopefully science will advance faster in the next decades with AI researchers helping

I have used iridium before, IIRC I paid 1 usd per KB, PER KILOBYTE (!!!), to track some stratospheric globes we launched in like 2014
