Here’s the synaptic weight churn vs vanilla STDP (and also without metaplasticity).
I got a little toy continual learning chatbot going (spiking LM using iuSTDP and dopamine based metaplasticity). No backprop. It starts off with random weights and learns (updates weights) an "ababab..." sequence as you chat to it. Will do a writeup soon. :)
Here’s a little toy reversible language I threw together a while back when I was going down a side quest to build a reversible bytecode language (like the JVM, but with a dual stack). I figure it can’t hurt to throw it out into the world. github.com/bringhurst/d...
Ty! Its opened up a ton of fun stuff to mess with. My next large post is either going to be on how networks can be modeled using stream processing (e.g. spike integration is a window, dopamine w/ STDP is a broadcast, spikes are messages, etc) or how we can chain them with async rendezvous circuits.
Interested in how neurons can act like logic gates? It's what my latest blog post is about: blog.typeobject.com/posts/2025-n...
A little thought experiment to use TrueTime (e.g. Google Spanner) to deal with timing across a hypothetical distributed spiking neural network: blog.typeobject.com/posts/2025-s...
I put together a little repo and website for this. I have no idea how far I'll get with it. snnp.org
Sentinel-terminated pointers in Zig are neat. I don't think I've seen that anywhere else. ziglang.org/documentatio...
I haven't decided if this is the first chapter in a sci-fi book or a design proposal: blog.typeobject.com/posts/2025-g... #worldbrain
A video of this meetup is available online now. See: news.ycombinator.com/item?id=4382...
I have a great picture of my daughter on the Incredicoaster from when she was 5 with a shocked face and hair blown back. It's still her favorite ride at Disney.
At the moment, I can't share anything that's not on the event page.
Just added ipa prounciation for Xinfra. It's pronounced ˈzɪn.fɹə. This site says it right: ipa-reader.com?text=%CB%88z...
I put together a quick blog post with the same content as the event pages just so HN doesn't filter it out: news.ycombinator.com/item?id=4370...
I think it was a not very well guarded secret… but LinkedIn’s stream team will finally talk publicly about their Kafka rewrite, many years in the making, called North Guard, as well as their abstraction on top of Kafka + NG, called Xinfra. Sign up here to hear about it: meetu.ps/e/NWkXx/466N...
I just updated it with a few tweaks and better cooking times. It works pretty well now.
Going to try to make some gingerbread cookies today with a recipe inspired by Milk Bar style cookies.🤞they turn out well. github.com/bringhurst/g...
An idealized circuit compiler in Wheeler. github.com/typeobject/w... I wonder if I’ll live long enough to ever see something like this run on real hardware (30 years out maybe?). #ReversibleComputing + #QuantumComputing == #HybridComputing
Brand new impractical weekend project just for fun: a reversible language. Haven’t gotten the parser working yet, but I posted a few examples of what I want it to look like. github.com/typeobject/w...
