I wrote a full terminal emulator in PHP! And I wrote a testing tool that takes screenshots of the terminal to verify that my emulator is working!

Mesmerizing to watch. And I've already caught a bug!

This is the biggest productivity cheat code right now. Kiss reading documents goodbye. You can get an instant summary of any document with this tool.

You can just do things??

You'd like my tests for my pixijs-layout library: Each componentTest creates a file in and if the new file doesn't match it fails. On first run I verify manually that it works, and from then on I get pixel-perfect assertions.

Now that's what I'm talking about. Great minds

Love the approach you took there. Really nice! 👌 Also, you got me at ANSI – (which is turning 10 soon, apparently 😱)

And now a full GUI in PHP? (yes it's possible, for example:

We're happy to announce our newest FPGA developer Felix; creator of "FreeDO" the first real 3DO emulator and a prominent member in the 3DO community. He also wrote DCX - the only commercial grade DC emulator. The future of #FPGAGaming is bright! #DoTheMath #MARSFPGA

I've been working on a Windows emulator for my research. I have now implemented the GDB serial protocol. Being able to debug my own emulator using IDA is just crazy. I love it. 😂

I've finally finished a full-fledged Seiko UC-2000 / DATA-2000 emulator. To be precise, I wrote it a few years ago, but only recently managed to dump the full firmware – thanks to Furrtek posting photos of the watch's MCU:

Trump: "President Xi just wrote me a beautiful letter. He responded to a letter I wrote because I had heard that China is giving weapons to Iran. I wrote him a letter asking him not to do that. And he wrote me a letter saying that essentially he's not going that."

It’s out March 6th, 2026! On my 26th birthday, I wrote, “I Took A Pill in Ibiza.” 12 years later, I feel proud to look to look at the lyrics of THAT song and know that NONE of them are true anymore. I wrote a completely new version of the song. This is, “I Went Back To Ibiza.”

nless is a TUI tool that is like Excel for live log data. It takes in logs, CSV or JSON and transforms them into columns in the terminal. You can then filter, sort, search, stream live data and more. Matt Pryor (mpryor on GitHub) made nless using textualize.io and is Terminal Tool of the Week! ⭐️

Now you can play GAMEBOY GAMES ON TERMINAL. Any good terminal that can run Sixel, iTerm2 or Kitty image protocol. (P.S: I wrote this at Christmas time, so still have to fix audio and normalize keyup)

xai former employee has to step down after revealing the roadmap for macrohard, basically creating a 'human emulator' that does everything. basically, jobs are gone and xai competitors now know their roadmap. 'we get a full human emulator we can put to work' near the end he even calls that the roadmap isn't public and continues haha, i love it.

We gave frontier AI coding agents 24 hours to write a complete Game Boy Advance emulator from scratch. GPT-5.5's emulator runs games best, with Claude Sonnet 4.6 and Opus 4.7 close behind. Gemini 3.1 Pro failed to produce a working emulator.

Netanyahu: "In 1993, I published an article in [the Israeli paper Yedioth Ahronoth] in which I wrote the biggest threat to the state of Israel is not in Arab states, but it is in Iran." (He leaves out that he wrote in the article that Iran would have a nuke by 1999.)

👩🏻: Is there a part in the lyrics where you thought, "Wow, I wrote this really well. Even I think this is great"? If there is a part like that for you… 🐹Well, I did write a pretty significant portion of the lyrics. My strength and weakness is that, with the good things, I tend to forget bad things really quickly. But I also forget good things quickly, so I can't remember which parts I wrote. 👩🏻: Hahahahahaha! Okay, okay, okay, okay, yes. 🐹: So, the song “With the Clouds,” I wrote a significant part of that. But, well, When I write, our producer reviews it with me, says what's good or not, and we write more. That's how we wrote it. I can't really remember which parts I wrote, can't really remember— 👩🏻: Well you wrote most of it anyway, right? 🐹: Yes, yes 👩🏻: It’s all good. It's all good. Everything's good. 🐹: Thank you.
