Cell therapy primed liver transplant patients to avoid organ rejection, small study shows

A few transplant patients in a small study were able to stop using immunosuppressive drugs, thanks to pre-transplant cell therapy.

Discourse is Not Going Closed Source

Cal.com just closed their source code, arguing AI has made open source too dangerous. After 13 years of building Discourse in public, we're staying open. Here's why.

📣 New blog post

Switching higher-order streams to first-order streams, https://mnt.io/articles/switching-higher-order-streams-to-first-order-streams/.

I discuss streams. It's a pretext to learn about higher-order streams, like `flatten` and to introduce a new stream: `switch`! It's very useful, and will have no secret for you.

Linux kernel is adding support for a new mechanism to validate lock usage during compile-time. It depends on a new Clang feature called Thread Safety Analysis.

"Implement compiler-driven static analysis locking context checking, using the upcoming Clang 22 compiler's context analysis features."

slab: support for compiler-assisted type-based slab cache partitioning

@melver posted a kernel patch that provides an alternative mode to RANDOM_KMALLOC_CACHES called TYPED_KMALLOC_CACHES.

The new mode leverages a Clang 22 feature called "allocation tokens". Unlike RANDOM_KMALLOC_CACHES, this mode deterministically assigns caches to allocations based on their types, and not allocation sites.

The Natural Numbers Game to learn #Lean is actually fun, at least for the first two worlds I completed so far: https://adam.math.hhu.de/

It works well enough on the phone for doing it on the bus also :)

i was quite surprised to discover that no one had registered deleteduser [dot] com, and was curious to see how many emails i'd get if i registered it, assuming many orgs 'delete' logic probably just overwrote the email address with [email protected] or similar.

The answer, is at least 3 different orgs in the hour that I've owned that domain and been listening for email.

And yes, all of those emails contain the actual PII of the person who has been 'deleted' :-D
