I posted a while back saying that if you're wanting to create a blog post with interactive visual elements, similar to the stuff I make, I would be happy to give feedback during the process and help where I can.
Owen took me up on that and I think the resulting post is really good! Take a look.

A lil' look at what's in the kitchen at the moment. Spent the day making this very high level visual of LLM inference.

A couple of weeks ago I moved my home office from the 3rd floor to the ground floor. 3rd floor was just way too anti-social, I prefer to be closer to my family.
My wife thought a dark wall behind me would be cool and I agree! Getting some shelves on Tuesday, can’t wait.

Alright, who have you got in your RSS feeds? I only have a few and I’d like more. Ideally the feeds where you genuinely read every single post they make.
Molly White would be in this list but I consume her stuff via podcast instead.

Got to the part of "temperature" and I'm aware that a higher temperature == less predictable but never knew why.
Turns out it's very simple. Before the "score" for a set of tokens is turned into a probability distribution it's divided by the temperature. Higher values "flatten" the distribution.

Are you going to Kubecon NA next week? The @ngrok.com team are going to be there at booth #1341. They're lovely and they have stickers and donuts, you should go say hi!

One of the nice things about using Lit now is that all of my properties and state can be introspected, and I can automatically create Tweakpane entries for them that update in real-time. This required no extra code on the component, all the information I needed was already there.

This looks absolutely beautiful, and I got my ass handed to me. Bravo.

My common frustration with ATProto apps at the moment is this. I don’t want to grant you access to modify and delete all of my data. I know that more scoped permissions are coming, but right now this makes me feel like I can’t get involved in the Atmosphere.

Visual clarity is still lacking but I’m starting to add layers on top of the map. These are the 8 PoPs ngrok has around the world. Lines between them are just for testing.

A little peak at what's happening in the work lab for you. Found a lot of places where showing stuff on a world map would work super well, so creating myself a great foundation to build that on.
It's a Robinson-projected set of SVG paths, and it comes in at 17kb.

TIL about ttyd from a post about ngrok on Reddit. Pretty neat combination for a DIY SSH if you don't feel like port forwarding or using Tailscale.

Well Uptime Kuma is just delightful. I was using uptimerobot.com but the 5 minute pings and various other limitations were a bit of a drag, and I have a Kubernetes cluster just lying around so why not use it.

It’s not obvious to me what happens in this step. You say it “sorts the matrix” but I don’t see that at all. The two strings swap places and one completely changes to an order that is very much not sorted. What am I missing?

Is this fixable?
It’s not the specific source, this happens during the TV boot screen and on the TVs own menus. Factory reset the TV didn’t do anything.
