Wrote a bit this morning on the internals of ML compilers, and how I'm going about porting JAX to pure JS

i feel a bit of emotional whiplash from past couple weeks, but it's been alright. good things that happened recently:. - ran into grade school classmate.- learned tensor calculus.- card game club.- company acq'd jamsocket(yay!).- back into jax-js.- used my notebooks product a lot.

some notes from nysrg today, running a couple profiling tools on uv and touring it a bit to get situated from the performance angle

the weather has no business being like this. it’s kind of a holiday in itself, strolling through a city under the sun

…and, 500 lines of code later, jax-js now supports advanced indexing!. it turns out this is roughly a "gather" operation, so I named it that internally in my IR, following XLA. however, backprop through this requires a "scatter" op which is much harder, so I'm skipping that 😅

i am currently in indexing hell trying to understand all the edge cases of numpy that I never thought about. apparently if you combine slices and broadcasted integer array indexing, it orders the axes, _unless_ the arrays are non-contiguous, in which case they hoist to the front

This month at NYSRG, we'll do some systems studies through the lens of performance by looking at open-source software and profiling them on some workloads. the systems: uv, vLLM, an image renderer in Rust, and various language/compiler tools in Go. the tools: flame graphs, ebpf,

tens of millions of hours have been spent on software that… records a mapping of keys and values.

somewhere, under all of the politics and business of this AI hiring news, previously-unheard names; there's an optimistic message that these researchers' work is finally recognized — just as all great work may be.

a milestone for jax-js — it's _working_ enough to generate and dispatch a few hundred GPU compute kernels for a Mandelbrot set render, all from your browser in milliseconds :D. (this does a separate allocation + kernel dispatch on each iteration, so it's a nontrivial benchmark)

btw modal is hiring for a product engineering manager. we have a very cool product engineering team that works with svelte to turn infrastructure into tech that developers love, since it helps them do more :). apply here

yesterday i voted and i think the most surreal part of it was that my family member who got all of us to go to the polls and vote for him is literally a wall st banker, like damn. i’ve never been very politically involved but it did feel nice to imagine what could be.

i think part of what makes moments like this tough for me is that i experience emotions pretty strongly, both positive and negative; and i’m also a little bit sad that i put a lot into someone who became important to me and left. anyway in other news i started reading diff geo.

it's been a wild past few months. i guess the only constant is the friends who i've known for years. there's something about people who lean on you and who you trust. love y'all hope i get to see you in brighter times when im less empty.

so i spent some time crying into a pillow and writing to try and reflect a bit on all the feelings and places and gems that make a connection special. next notification is a vc networking email. man it never ends. o well i have lots left to do.

oof to make things worse this girl just broke my heart and i’m sad :( but also it’s nice to get a bit of closure. what a beautiful problem to have, to miss someone. at least i’m old enough to deal with it now.

broken promises hurt.

it ain't much but it's working! (jax-js / via webgpu)

today I took some notes from reading thru the rectified flow lecture notes today at — idk, not really an ML person but I do like cool geometry.

“i hope we can live forever. not living as in the opposite of dying, but like, … you and I, how we lived today, together”.

some of the best feedback a systems person can get is a team of _very good_ engineers evaluating you, vs others / building a simple version themselves. it's easy to beat tech from the past, but much harder to be faster, simpler, more reliable, more efficient than contemporaries.
