rkwasny··on Ask HN: How do you manage on-prem servers?
Ubuntu MAAS to provision servers - when new server arrives guys at the DC just need to plug it in and power it once, everything else is just clicking around.

Pyinfra to manage and install software (I'm fed up with custom DSLs, pyinfra is pure python)

rkwasny··on Tesla AI Day 2022
I think the problem is not in the robot hardware but in the software, same as with self driving cars.

What would help the development would be a "standard" hardware platform one can just buy and add own code.

rkwasny··on macOS for Web
Feels a lot snappier than the real thing :-)
rkwasny··on The Cost of Cloud, a Trillion Dollar Paradox
I think the problem is using "the cloud" eroded knowledge of physical infrastructure in new DevOps guys.

Going to the DC once every few months to add new servers was a good way to remember how to deal with hardware and train new people. I used to take interns/junior devs just to show them how it looks.

rkwasny··on Please, don't build another Large Hadron Collider
The target never is to just "build" bigger LHC.
