Ghostty Devlog 006, speed edition 🚀. An intro to SIMD, clever unicode lookup algorithms, and CSI parsing fast-paths all in order to make Ghostty wicked fast. The video below compares the plain-text throughput of Ghostty to another popular macOS terminal. Note that this video only showcases one particular type...

Cursor position and color uniforms are now available to custom shaders in Ghostty, enabling cursor animations (and other effects). Video below is a rough demo of something simple. Can't wait to see what the custom shader community does with this. :) Docs:

Even with close confirmation I sometimes close my terminal and think "OH FUCK NO." Coming soon to Ghostty, you can undo that. 🥰 (Technical details: we keep the terminal running for a configurable time in the background before terminating for real, similar to email undo send). (macOS only for now, AppKit APIs provide a nice undo manager implementation that eases this quite a bit. I still have to do research on GTK for Linux.)

Look at the speed at which this model generates video! Imagine a chat interface that uses real-time video streaming to talk to us instead of text. We are getting close!

Claude Mobile starts the idea... Ghostty finishes it I basically use Claude Mobile as a notepad now. Whenever something comes to mind, I open the app, pick a repo, and ask Claude to start exploring. Then I just let it run while I go on with my day. Later I jump into Claude Desktop and I’m right back in the same session, with context, structure, and a clearer shape of the idea. I tweak a few things to set up the coding phase. Finally, one click to Ghostty (video), open a couple of worktrees, and start working on the PR. IMPORTANT: when you move to Ghostty, it must be the exact same repo you started on mobile, otherwise the --teleport command will fail

Video Fact of the Day: The M1 Challenger Tank can accelerate from 0-717.5mph in just 8.0085secs and on to a top speed of 800.85 (Mack 71.75), so fast that it disappears into a puff of smoke! Filmed from a Canberra

There is a "flash" bug in the One UI 7 Beta1 animation. In fact, there are at least three versions of this problem. Samsung seems to have not found it, so it has not been solved. You only need to open two apps in succession a little quickly (not particularly fast)，You will see a quick flicker in the picture. The first video is played at normal speed, and you can see a flash picture. The second video is a slow video, and you can see the moment when the soul of a page flashes in the ninth second. I call it the One UI 7 haunted event.

Grok video is getting really good at photorealistic outputs. IMO, this is one of the hardest styles to nail because our brains are so attuned to anything that looks "wrong." And the speed of progress here is kind of unreal.

🇨🇳Teleportation isn't possible yet, and if an aircraft accelerates that fast, it would instantly kill the pilot due to extreme G-forces. So the question is — is this video real, or AI-generated? Because how could a pilot survive such speed?

First sighting of a Waymo in the wild in London. Immediately noticed how many drivers are impatient and aggressive when sitting behind a vehicle that is programmed to abide by the speed limit.

traders, very soon I will make your life easier and help you multiply your capital a terminal with scalping mode is no longer a dream, but a reality that I have already taken on this terminal promises to break all boundaries and provide more opportunities for trading what I want to implement: > scalping mode: you will be able to trade lightning fast, open orders, and close them, just like in real scalp terminals > built-in indicators: everything in one place, no need to go anywhere > unique UI: To be honest, I'm tired of the boring UIs of other terminals, I'll make it really modern these are just the beginnings, but the most important part is done - I've started maybe you wanna try this? pre-alpha soon...

And when I say highball they HAD to highball to make thjs fight interesting lmao First cherry picking Metal’s scales, ignoring the whole purpose of him being a copy of sonic, therefore ignoring all of Sonic’s scaling post forces, (not even counting idw and frontiers), keeping him lowballed in some areas The highball of Cell’s speed is laughable, like an explosion speed isn’t comparable to mobility speed, and of course they HAD to use the filler goku traveling to hell to make it even arguable lmao, ignoring all the modern sonic speed feats and keeping it very toned down Overall the results were funny since they couldn’t just show how one sided it truly was, and of course DA cooked with the animations, good luck to him and his future projects

One of the many things that make the Princess of Wales dufferent from Madame Moonbump is her awareness of and concern for others. In the video clip we see Catherine suggesting to the group that they all go inside to get out of the rain, and she starts to lead them in. But she stops and looks over her right shoulder and sees another group of kids with no umbrellas! At the end of the clip she heads over to them to help other adults shelter the children, resulting in such lovely photos such as the one below. 🥰

Yesterday someone suggested I create a fight between Alucard and Drolta Tzuentes using Kling AI 2.6. I usually work with Text to Video, but in this case I had to use Image to Video. The base image is a fusion of two images created in Niji and combined with GPT Image 1.5. Then I added the right prompt to give the fight speed and dynamism. The result isn’t perfect, but it’s pretty cool.

A lot of you are thinking that the spring which we will supply to Prakash Dadlani will be produced at the speed of 1304 ppm. That’s not true. All springs are not made on one kind of machine. The CNC machine we built that produces springs up to 1304 ppm manufactures compression springs. Whereas, the springs for Prakash bhai will be made on one of our 12-axis CNC wire forming machine. And on this the speed is much slower but it has flexibility to produce a number of different kinds of springs and wire forms. The design, type, materials, wire diameter and profile, features and precision of the springs defines what kind of machine will be used. It’s not one machine that does it all. This video is of that springs being manufactured on our other CNC machine. Also, the operator is setting the spring up that is why he is using his hands. Once it’s in production, there’s a crate underneath the machine for the springs.

I’m trying to get this intersection fixed on Market in the Castro in front of Bar 49. I shot this video yesterday while walking to dinner. Anytime of day you can see cars aggressively almost hitting people in the crosswalk. This is because this intersection is so wide that, for one of the right turns on green, you can’t see the pedestrian crosswalk signal at all and you have time to speed up heading towards this crosswalk. Many of these drivers assume you are jaywalking even though you have 20 seconds left to walk. This leads to some frequent aggressive behavior and near misses with pedestrians. The drivers assume this configuration wouldn’t have the crosswalk active at that time - and I agree that it shouldn’t be.

Starlink is one of those rare technologies that feels like a cheat code for life. Plug it in, point it at the sky, and high-speed internet is literally beamed down to me from space. Technology is the closest thing we have to magic in the real world.

Another video of public mocking and wondering that people are able to play their music of TMC chor song in Kalighat, home of Mamata. Important thing to note is the street in that area is completely broken. She didn’t even take care of her own area.

If you play soccer and lacrosse you already know that acceleration and top end speed are vital to performance. However, just being fast in 5-40 yards in a straight line is not enough. Weaving. Curving. Dodging. Rotating etc.. are all other factors that must be considered. Being fast on a curve/angle is vital to performance. Be sure to train the edges!

Sometimes young children’s “incorrect” answers can tell us as much about their growing knowledge as the “correct”ones. Check out this clever little guy, shared to TT by breanaterrymccool. Asked how fast he can run, he replies with an amazing answer: 45 pounds. Now take a moment to consider all the knowledge this response actually reflects. He knows he’s fast… really fast. So he chooses a big number. But is there more than random selection at play here? I can only speculate as to its specific selection, but it’s not lost on me that 45 is a number routinely posted on non-interstate roads as a speed limit in the US. We don’t know for sure whether this influenced his choice, but you’ll notice it’s not 47 or 68. It’s a round number he may well have been exposed to as an indicator of speed while traveling with his family. Then he needs a unit of measurement. In this case he selects the wrong one, but there’s also something very right about his guess. He knows that pounds is a term often used to help categorize quantity. Think of all the different units we use to measure speed, weight, height, volume, distance… there’s a lot to be learned, and despite his tender age, he’s already in the ballpark. Such a wonderful window on his growing mathematical knowledge.

Paul Curry, an amateur magician in New York City, was the first to discover that a square can be cut into a few pieces and the pieces rearranged to make a square of the same size that has a hole in it! There are many versions of the Curry paradox, but this one is the simplest.
