NEW ANALYSIS: UK emissions fell 2.4% in 2025 as coal fell to a 400-year low. Incredibly, we used less coal last year than than in 1600, when Queen Elizabeth I was on the throne and Shakespeare was writing Hamlet.

Breaking news: Max Headroom, one of the greatest TV shows ever made, is free on Tubi.

I find the terrible Tubi ads really enhance the dystopia.

A few years ago I designed a way to detect bit-flips in Firefox crash reports and last year we deployed an actual memory tester that runs on user machines after the browser crashes. Today I was looking at the data that comes out of these tests and now I'm 100% positive that the heuristic is […]

The A18 Pro in the MacBook Neo is 19% faster than the M2 Ultra in the Mac Pro in single-core performance (Geekbench 6).

The MacBook Neo starts at $599.

The Mac Pro, which is still for sale, starts at $6,999.

Batman Forever homepage, 1995

The Batman Forever website, launched in May 1995 by @zeldman and friends, was cinematically visual. And this was a period *before* HTML tables had arrived! See my writeup for the full story: https://cybercultural.com/p/1995-web-design/

Tweet by @trq212 about Claude Code rendering scene graph in 11 ms and printing it to terminal in 5 ms

Tweet by @jarredsumner about Claude Code memory usage growing from 10 Gb in January to 68 Gb to 1.7 Gb now

Gotta give it to Claude Code developers: they are exceptionally brave. I would’ve been straight up embarrassed to show stats like this.

Reminder: Claude Code is a thin CLI client that reads input from your terminal, sends it to Antrhopic servers and prints back the response.

Sorry for the…typo? Something? I pre-wrote the earlier toot in BBEdit and then copy/pasted it! I did the same on Bluesky, with minor edits, and there was no weirdness there! (I didn’t edit the part that had weirdness.) Weird…ness.

Dianna Cowern (aka Physics Girl on YouTube, and possibly @dianna) has been fighting COVID-induced ME/CFS since 2022. ShevqeIeIcDHD0d her first video in three years:

I got distracted by the Marathon “server slam” test and missed the ARC Raiders expedition window 😕

@Migueldeicaza Apple has never been able to update its website worldwide at a specific time. The changes always take a while to propagate.

⭐️ New blog post: A Month With OpenAI's Codex

https://highcaffeinecontent.com/blog/20260301-A-Month-With-OpenAIs-Codex

It's been literal *years* since I last posted anything, so you know this is a big deal for me 😜

@ianRobinson Same here, sometimes.

Apple Teases 'A Big Week Ahead' With Announcements Starting Monday Apple CEO Tim Cook today teased "a big week ahead," with announcements starting Monday. His post included an #AppleLaunch hashtag with a colorful Apple logo, along with a short video that ultimately shows an Apple logo on the lid of a Mac. Apple is reportedly planning a three-day stretch of product announcements from Monday, March 2 through Wednesday, March 4, with up to five new products expected to be unveiled, including a lower-cost MacBook, an iPhone 17e, and more.

Does Apple still not have any official accounts on Mastodon (or Bluesky)? Are they really still using X as their primary (only?) text-based social media platform? https://www.macrumors.com/2026/02/26/apple-teases-a-big-week-ahead/

@spitfire …but one is more correct.

@spitfire (I think you mean file name extensions.)

I'm about to embark (hah) on my second expedition in ARC Raiders…right before switching to play a whole lot of Marathon starting in March. But if you want to hear my thoughts on ARC Raiders after ~270 hours of play time, check out this episode of @incomparable where I talk about it with some […]

Mario Guzmán (@marioguzman@mastodon.social) Attached: 2 images I will never understand how the most important, and *main* set of controls was reduced to a very tiny area that isn't very prominent and easily gets lost in muddied Liquid Glass. This is a prime example of how to NOT design with users in mind. At a glance, it's hard to even find it in the second screenshot. In the first, it's difficult to read its contents. Not to mention the volume, scrubber, and time labels now take two steps to interact with them.

@jjviii It’s terrible. @marioguzman has been posting about it for a long time. Here’s a recent example https://mastodon.social/@marioguzman/116087859949758592

@b3ll I’m still using Xcode 26.0.1!

today in "cursed aliexpress items"

@avakining Check the “About” menu item in the Hyperspace menu.

@Squozen The rates are lower at certain times of day, but not zero (or negative) like solar.

@ianRobinson 🙏

Also, all that talk about OLEDs and you got an LCD anyway! What model?

@ianRobinson I've gotta believe there's a way to win you back!

@ianRobinson The good news is that there’s no AI at all in the follow-up or topics for the next episode.

(The bad news is that there are a couple of AskATP questions on the topic…if we ever get to them.)

An iOS screen showing the Siri command “Hey Siri lights out” with a list of media containing the words “lights out” in their titles. (Siri did not turn off the lights.)

This is pretty much the only thing I ever say to Siri for home-automation purposes, and I say it exactly like this, word for word. Today, Siri decided to get creative and try something different.

@donw I had forgotten this feature even existed.
