do the people getting bent out of shape over this, despite apparently having no clue what it is or does, also fly into a vicious rage over, idk, spam filters? i must have missed the seminar on differentiating Good Linear Algebra from Bad Linear Algebra

Quantization from the ground up | ngrok blog A complete guide to what quantization is, how it works, and how it's used to compress large language models

I spent 2 months learning about quantization and am extremely proud of the post I've written about it. I think these are some of the nicest visuals I've ever made, and I love how this compression technique invented in 1898 is being used on the bleeding edge in 2026.

Yesterday was my last day at Deno.

From today, I'll be cheering the talented team on from outside the org.

This also means that I'm now considering my next move in the DX/DevRel/Technical marketing space.

Video

DOOM fully rendered in CSS. Every surface is a <div> that has a background image, with a clipping path with 3D transforms applied. Of course CSS does not have a movable camera, so we rotate and translate the scene around the user.

Surely this couldn't make anxiety any worse.

I have taken many an afternoon nap these past few days.

Yeah, good call. I tapered off from a couple cups to one cup, now zero, but I'm sleepier than I expected to be. I didn't realize how much caffeine was just keeping me at a baseline of alertness.

I've gradually reduced down to one cup and now I'm on 0. I'm thinking that green tea might be a good 0.5 cup compromise right about now.

Yeah I don't know if this is a long term thing for me, but I figured before I ask my prescriber for anxiety meds, I should stop taking the substance I know isn't helping my anxiety lol.

I might come back if this doesn't change much.

Yeah that's a good call, I should go for a walk just to get the blood pumping.

I'm lifting, but I think more cardio could do me good.

When you like an article, I like to make it in video form.

Here it is, including excerpts of the songs mentioned which will (hopefully) immerse you deeper in the story.

Love to you all.

I'm trying to quit caffeine to help with anxiety, but man now I'm just so sleepy all the time.

Any tips?

That’s a good approach. I should adopt that.

But I should also be doing professional development because I'm definitely falling behind in all of the ways and won't be employable soon.

But it is Sunday and I should rest and have fun.

But that house project still isn't finished...

Ah yes, Sunday anxiety. Can't relax because I should be doing chores. Can't do chores because I should be relaxing. So I'll do neither until Monday comes.

I accidentally bullied Jason until he lashed out at someone else.

Worth it for the content.

You probably missed it! Yesterday I put out a great episode of my comedy web dev news show.

It only has ~300 views, so sharing it with friends is SUPER appreciated.

If I wasn't correct I would be deeply apologizing right now.
