But realistically: mainly cat photos, food and wine, and bad jokes.

Whodathunk that the AI trained to emulate Nazis on a Nazi website owned by a Nazi who is determined to spread Nazi propaganda would end up sounding like a Nazi?
One of my colleagues AI-generated this image of me and... checks out, I guess?

Super blursed switch. 10/100, but supports up to 55W PoE per port. There's a mechanical switch in the front to put each PoE port on a separate hard-coded VLAN. The power cord is built in. And it has a pair of uplink ports but no way to configure LACP.

Weird free item from Amazon Vine.

Italic is not the slant, it is the letter shape. True cursed font knowledge begins with CMU Serif Upright Italic.
cyclotrons have cool magnets
Geology museums are neat because they're just an institutionalized version of "come check out this neat rock I found."

Operating a Certificate Transparency log is now within reach of many organizations.

I wrote up the requirements: essentially one small server process, a couple people, and the capacity to host 3-5 TB of static files. https://words.filippo.io/run-sunlight/

I'd love to chat with anyone who's considering running one!

You Should Run a Certificate Transparency Log

Maybe you, yes you, should run a Certificate Transparency log. It’s cheaper, easier, and more important than ever.

@mattg here is a photo of all three of our cats on a walk.
@dev the admin team woke me up early today to install the updates

I can't stress enough how close U.S. science is to the cliff.

"Numbers released in May by the National Science Foundation (NSF) indicate that if Congress approves the cuts to the agency proposed by the White House, the number of early-career researchers it supports could fall by 78%" (via https://www.science.org/content/article/it-s-nightmare-u-s-funding-cuts-threaten-academic-science-jobs-all-levels)

@elforesto a mechanical switch for VLANs is not a thing I was expecting to see today
@ricci @elforesto need to get one of these and sneak it into the rack of 800GbE switches I just had deployed
@dan @elforesto use it to power them with its mighty PoE
@ricci @elforesto do you think I can power the big GPU servers over PoE?
@dan @elforesto you just need enough ports, Ports

@ricci @dan @elforesto

Plug in the jack, Jack.
Flip on the switch, Switch.
Just get yourself PoE.

@ricci @elforesto back in the day, all of our VLANs were mechanical

(Pixel for scale)

@dan @elforesto really though I'd imagine the first switches that supported VLANs must have been configured with a bank of DIP switches on the back, right?
