Technology generalist and amateur historian. Always remember to question the context.

Got to see the Geysers geothermal complex again today. Still surreal to see the steam we use to generate power be acquired simply by drilling a deep enough hole.

More datacenters should have creatures dedicated to keeping the halls bug free.

Recently bought a Supermicro H11SSL and was saddened when a BIOS update caused it to fail to post.

It's got two variants - 1.01, which is Naples only, and 2, which supports Naples and Rome. The major difference between the two is the size of the SPI flash: v2 is 32MB while v1.01 is 16MB.

It turns out that v2 just has two copies of the data - if you take the second 16MB of v2 and flash them onto a v1.01 motherboard, it'l happily support a Rome CPU.
