There's no celebrity actress to promote it, there's no benchmarks (faked or not), there's just me using it since years to manage my own todos and since last year support to manage agent context with it: no bold claims, eddoapp.com is just my very own memory palace.

@badlogicgames congrats, what a nice surprise!

People of pi. BIG NEWS. I've sold out. Let me know how you feel about this in the comments below. mariozechner.at/posts/2026-04-…

@punkpeye hey what's up with the FastMCP repo on github? Worked for me yesterday and now getting a 404 😬 github.com/punkpeye/fastm…

hot take question: is really Claude Mythos such a leap in finding vulnerabilities or is a huge part of it deciding to spend huge amounts of tokens on the search for it?

i might have said the same over the easter weekend trying to understand what local catholics are celebrating.

agents as glue like APIs were in the golden Web 2.0 mashup days. not a computer scientist by training, I always felt more like a mashup artist instead of a real software developer.

You clicked what you thought was an event invitation. That's all it took. Elastic Security Labs breaks down SILENTCONNECT, a newly documented loader that hides behind a Cloudflare CAPTCHA page, downloads a children's story VBScript, and silently installs ScreenConnect on your machine. Key findings: • Attack starts with a fake invitation link redirecting to a Cloudflare Turnstile page • VBScript disguised with a children's story decoy pulls C# payload from Google Drive • Compiled and executed entirely in memory via PowerShell • PEB masquerading makes it look like winhlp32.exe to fool EDRs • Active since March 2025, largely undetected until now Full analysis + YARA rules + detections: go.es.io/4scBAmV

Okay, time to hang out the shingle! Need a programmer? One who has seen and done everything? One who specializes in game development but has also done work in the medical and consumer electronics industries? Look no further!

@Scobleizer @SawyerMerritt IMHO: This is less about what people like, more about what works and what doesn't. A car is moving, bumping along, accelerating, slowing down. Large touchscreen and your fingers will just jiggle around with relative movement and miss that touch button and hit something else.

Mercedes-Benz engineers told me the reason for this. When they do consumer research, most people like tactile things: buttons, knobs, sliders, and stuff like that. They like the tactile experience. The problem is, if you stop there, you make mistakes. The world is moving toward an autonomous vehicle future where everything is done automatically with screens. The consumer can't tell you about that world because they haven't thought about it or been presented with it yet. As a result, the auto industry continues serving the past and not the future. Ferrari is just an example of that. They are selling to old people who have a fuckload of money. That doesn't mean these people have any sense or any care for innovation; they over-index on the physical experience of being in the car because they can't imagine a world where a car would drive them around. That is certainly true of the rich class in America. I hung out with them last year. They love their old mechanical cars because they can afford them, and Ferrari has to compete with that old mechanical car mentality just to sell them another $500,000 vehicle. Tesla, on the other hand, is going for the everyday person. And the everyday person knows it's stupid to rely on buttons when you can have a touchscreen like the one on your iPhone.

A large touchscreen does work in a car if you have great software. The Model Y became literally the overall #1 bestselling car in the world just three years after launching partly because people loved the software experience (among many other reasons).

@badlogicgames In Kitzbühel gab es auch einen kleinen Vobis und einmal war ich dort und Peter Weck kam vor mir dran und hat glaub ich eine Kugelmaus gekauft.

omg this was my exact machine minus the monitor and printer. i loved its design so much.

that's why eddo allows you to manage granular nested tasks organised with stop gaps and quality gates. eddoapp.com

One of our researchers built an AI powered supply chain monitoring tool on a Friday afternoon. The following Monday night it caught the Axios npm compromise before most people knew it existed. Elastic Security Labs is open sourcing the tool. Full story by @dez_ here: go.es.io/4bOfsuq

recommended reading build.ms/2026/4/1/the-c…

We open sourced the tool used to detect the Axios supply chain compromise! I built it Friday after a red eye home from RSAC. Also, wrote up the full story, including the hectic moments after that first critical alert github.com/elastic/supply…

I suspect tweaking and trying to optimize how to run U9 prepared me mentally for the years of web dev cross browser quirks across netscape and ie6.

looks like I sold my Razer Core X eGPU too early when I gave away my Intel based Mac Mini 😭

@badlogicgames there are many markdown editors, but this one is yours!

welp, vibed it in an hour. i really only needed single writer, multiple readers/commenters. easy enough. github.com/badlogic/jot

You can spec the shit out of everything as much as you like, there will always be something you'll miss. At least in my experience, iteration and quick feedback loops were always the way to go. It's as if creating lots of UML diagrams would save you from creating bugs. 2/n

I'm more an autodidact mashup artist than a real software engineer. So I might be missing something when there are now folks claiming better planning/specs done with agents will help one-shot implementations and eliminate the need for human code review. 1/n

@Elijah_Meeks guess the idea of chart junk also got quite debatable over the years.

Tufte has very good design sense & deserves credit for popularizing information visualization but many of his most iconic ideas are flawed. The Challenger example, Minard's Map emphasizing General Winter and the Powerpoint takedown have all received and deserve criticism.
