Hypermedia practitioners unite!
Calling all employers — If you are hiring for a stack with a big back end (you know who you are), post your job with @lexandermorgan new site

As I talk about in the episode linked below: there are more of these jobs than it might appear!
Definitely not for everyone. @htmx_org is html for gen-Xers. It's in the name!
Hey @RhysSullivan when adding an integration to Executor, is it better to go with the mcp or the cli if they're both available eg for github?
I'm sad to report that nobody plays #eightile in Galician, and that Spanish and French aren't much better.
Designing a new bathroom with @tldraw and I noticed the counter-clockwise keyboard shortcut doesn't display correctly. It's shift + , but it just shows up as shift. tldraw is definitely worth a try 👌
With memory prices skyrocketing, the best quick fix is for software to become more mem efficient. Time to dig in to mem optimizations!
Palomitas is done! 🍿
It's a game where you're a pigeon scavenging for food. Part of #vibejam 2026.
palomitas.pages.dev
Palomitas is now up and running for #vibejam
You're pigeon that tries to steal food. Cool idea but not really fun yet. Lots of work to do still.
I just spent ~90min vibe-planning my entry for #vibejam
How do other people go so much faster? If you're not actively participating in at least the plan I don't get how you learn anything from prompting.
Open letter to @NYCMayor asking for the removal of NYC's harmful trash subsidy. If you're wondering how cities subsidize trash creation and littering, give it a read.
@classiclarryd I can never get H100s on PrimeIntellect with pytorch pre-installed so the docker builds don't work. With Ubuntu I get slower nanogpt runs (88s) without changes, but 85.6s on my branch with changes. Does this mean mine would be a record if it ran with docker?
I'd raise a pr but my branch is suspiciously the same exact runtime as the record 🧐 github.com/alexandermorgan/m…
Hey @marclou, I'm trying to post a website for sale on TrustMRR. It doesn't have any revenue but I am still required to submit a Stripe key for it. I see that there are other zero-revenue listings, is there some way around the Stripe requirement in this case?
Last month at PyConES I shared my approach to safely batching BPE #tokenization merges. This boils down to:
1. Deciding whether a pair is safe to merge
2. Determining how many pairs to consider in a single batch
Together these 2 points mean the freq. of any token pair, eg "th", can only decrease as it's fragmented by other merges, eg "_t" or "he". So later there can't be other pairs with more than whatever pair you're considering merging since neither of its tokens have been seen.
Batching tokenization merges is the main optimization I integrated into BatchBPE, my fork of @karpathy's minbpe. It gives a ~300X speedup! It would be great to see this approach used in a tokenizer written in a different language.
