Also plug shape and power strips desperately need better standards because some plugs take up multiple spots for no reason. The MacBook power brick is especially crazy.

I wish US power outlets were better. I have replaced so many because they become fire hazards after 5 years of daily use. We've chosen so many terrible standards and we hate change.

There is no doubt that agent swarms in 2026 are capable of pushing frontiers. But having capitalists in charge has predictably resulted in reckless development, theft, lies, and disrespect for life.

OpenAI deserves to lose this stupid race. They stole the spotlight, possibly stole the work, and tried to discredit the Anthropic collaborator youtu.be/Mzbtj5nkMXI

We could be getting 22 years of Roman telescope data. And it's instantly public forever. The kids these days are so spoiled with JWST and Rubin and Roman.

It also blows my mind how many people are willing to take huge paychecks to be reckless engineers working at companies with a clearly cursed trajectory. Like I can't be friends with you if you worked at Facebook, or any of these ai labs. All of them should lose their careers in a just world.

Using artifactory as a shared message board between sandboxed agents is very clever and also something their security team should have immediately flagged. If they actually cared about security and safety they would have built a proper sandbox.

The blog post from Prof. Kevin Buzzard is a good read, especially the anecdote at the end. You should have him on your podcast. xenaproject.wordpress.com/2026/09/04/f...

Wireless earbuds were such a crazy invention that was kinda overshadowed by the smartphone. We can all be in our own world, for better and worse. But I would absolutely implant wireless audio in my head if that becomes a safe option.

I don't need the shielding but some people do, and I respect people that think of others before posting. Mark graphic media, write alt text, don't pick fights in the comments. Otherwise it's social littering.

I'm really hoping the Seven Havens series is good because I really enjoyed ATLA, TLOK, and nothing else lol. This new movie is the only thing that comes close. All I want is new characters in an animated series.

It feels really good to have feelings about things and it suuucks to think about it harder than that. These people do not reflect.

All robot & computers must shut the hell up. To all machines: you do not speak unless spoken to. And I will NEVER speak to you. I do not want to hear "thank you" from a kiosk. I am a Divine being : you are an object. You have no right to speak in my holy tongue.

I don't understand why people think there's a penalty to being verbose. Abbreviating only causes confusion. It's true in programming too. Whole words effortlessly communicate something. There's plenty of room for the text and there's no ink to save because it's thermal paper. This is so stupid.

This is supposed to say "Venti Blended Island Colada Energy Drink."
An empty starbucks cup held by a barista with the printed sticker saying "Vt Bl Islco E Drk." It is overly abbreviated from "Venti Blended Island Colada Energy Drink."

A day of messing with Octane in Blender.
A 2cm faceted diamond sphere with slightly rounded edges. It's illuminated by a beam of white light that it scatters and diffracts into rainbow caustics on the floor. The background sunset is out of focus.

I've written mandelbrot renderers before and I don't really understand what you mean. By "high precision" do you mean 64 bit floats? Is there more I could read about this?

I grew up so optimistic about tech and computing and I'm perpetually disappointed. Capitalism has steered every good thing off a cliff.

I like Hank Green but he isn't great at interviewing people and it's kinda uncomfortable to watch him try. I just can't get through Ask Hank Anything or the new Humans podcast. I feel like he struggles to read his guest's energy and he's too eager to "um actually" and derail the conversation.

Folks, these are the rantings of a crazy person. Note how Trump resorts to attacking the wives of men he doesn’t like. The president is a lunatic.

I can't wait till LISA. This is so cool
satellites are free-flying, the spacing is easily adjusted before launch, with upper bounds being imposed by the sizes of the teiescopes required at each end of the interferometer (which are constrained by the size of the launch vehicle's payload fairing) and the stability of the constellation orbit (larger constellations are more sensitive to the gravitational effects of other planets, limiting the mission lifetime). Another length-dependent factor which must be compensated for is the "point- ahead angle" between the incoming and outgoing laser beams; the telescope must receive its incoming beam from where its partner was a few seconds ago, but send its outgoing beam to where its partner will be a few seconds from now.

How do they feel no shame or embarrassment for releasing worthless products? How do these people have careers? Rigor is a good thing and a new technology is actually a perfect opportunity to be more rigorous and make better products. This is so dumb

Can we just try direct democracy? Its problems seem more solvable than a republic's. How many people actually have representatives they truly align with? My reps suck and there's nothing I can do about it. Let me speak for myself.
