it’s also the day 16 years ago I discovered that a customer for the data center I worked at had racked 3 full cabinets with over $200k of brand new server hardware on top of $80 of canned soda from our customer lounge vending machine to avoid spending $600 on mounting rails

We just released Tap, a tool designed to handle the hard parts of repo synchronization, so you can focus on building your application.

It's now easier than ever to stay up to date with Atmosphere records for dev, data analysis, or any other task at hand!

to sincere post a bit:

the ability to receive important timely updates like this one, from regional govt and institutions like this over an open protocol (vs closed/proprietary platforms) is a huge part of why I work on AT

The AT Protocol PLC Directory allows a higher-priority rotation key to revert a key change for 72h.

But what good is that window if you don't know about a change?

Well, here's an Atom feed generator of PLC operations for any handle/DID.

Any moots know any great systems SWEs with networking focus looking for a new gig right now? A good gauge is if they've recently written any eBPF programs. Go background is also a plus. Figured I'd toss out a line.

“The average American town has 2 stroads” factoid actually just statistical error
