Hi, I’m a sighted alt text user! Here are some reasons I use it: - Slow Internet on an airplane - I’m over 40, I have no idea who that celebrity is - Bluesky broke images again - My vision sucks and that text is too small to read otherwise - Conveys further context and authorial intent

Out of a wreckage of a dying star, a new planet was born. And now that planet is evaporating like a comet, leaving a trail that whips around the star every 4 days. It's a remarkable story written in chemical clues. Nobody has ever seen anything like it before. 🧪🔭 esahubble.org/news/heic2613/
It looks like decompiling has a good AI interface now: rea (Reverse Engineer Anything) brings together the binary decompiling and profiling tools needed to rip apart any binary with MCP interfaces. github.com/morluto/rea
Productivity as an adult is just an endless process of applying new psychological tricks and operant conditioning to yourself until an acceptable number of tasks are completed.

this piece says ai psychosis is a "real documented phenomenon" I was like, what?? because I pay a lot of attention to the clinical lit on this
This is great from @adamsinger.bsky.social, about how using #AI agents is to cede our agency. I have noted the same mechanism, but it's particularly notable that it's being pushed by people who obsess over the precise key caps in their keyboards, but don't think anyone else should do the same
i was fortunate enough to profile Margaret Hamilton in 2019. A really kind and curious person. This was my favorite story she told me:

"Is your product legible to coding agents as users?" I can just smell Christensen's Innovator's Dilemma as I switch from better, more polished, established products to ones that let me point an agent at them. Of the nine points at blog.exe.dev/revisiting-j..., this is the most important one.

Joel Spolsky's twelve questions still hold, but agents demand nine more. Call it the Shelley test.

This is well-known to those who have been running VMs for a while but is not easily learned if you're new to the space, so we figured it should have a blog post. We have also exposed control over kernel scheduling cookies in a way we believe is novel.
Sharing a CPU core comes with a security tradeoff. At exe, your team’s VMs can share cores with each other. Other teams’ VMs stay separate. And if your own VMs need that separation too, your team admin can turn sharing off. Ian explains how it works: blog.exe.dev/crossing-the...

If you don’t take the time to write the words—if you have an LLM build a composite document for you—your end product is not worth reading. It wasn’t worth it to you to write it. Why is it worth anyone else’s time to read it?
Lots of websites share an IP address. Somehow, you still get the one you asked for. Philip on the humble Host header, plus a new way to serve subdomains from a single exe VM: blog.exe.dev/the-hardest-...
