Open source is your biggest internship

19-year-old me merged a tiny Jenkins Pull request and that commit snowballed into GSoC, the Linux Foundation, the Kubernetes release team, and eventually Meta.

Hard agree

most ppl’s refusal to risk humiliation is their original downfall.

genius is indistinguishable from delusion / being a moron until the outcome arrives.

the funniest part is that when it all works, everyone retrofits the narrative to make it look inevitable.

& when it fails, they call it what they were always going to call it. stupid.

the line between idiocy & insight is fine as hell.

Thank you

“Why argue with an Arsenal fan when you can just wait?” We waited. We won. We are champions of England - and we are just one game away from being crowned champions of Europe. Read my piece on what Arsenal means to me here: https://t.co/J6cg388mRH

It is my understanding, there is a seriously confident expectation now for a decision on the Man City 115 case to be delivered in the coming weeks ( sometime in the summer latest )

All Premier League clubs await official communication.

[Gabriel Magalhaes @biel_m04]

sorry fans, we will get out of this situation. we need you!

15 years I’ve been on this journey.
We’ve been down in the dumps for most of it I’ve seen some of the worst defeats in my time.

But it’s all worth it

What I’m seeing with the GPU rush is truly remarkable

if you are in college in india in 2026, the market is not dead, it is just filtering harder I was reading an India Skills Report 2026 puts employability at 56.35% which means you need to do something different to stand out and get your foot in the door

one of the easiest health wins is fixing your sleep start time

I’ve tried sleeping 30 minutes earlier for 7 days and it’s starting to make a difference

i dont think AI kills software engineering

I think it kills shallow software engineering

if all you know is syntax then yeah it gets scary

Better than Netflix. I got my dinner time watch sorted

Did a very different format with @reinerpope – a blackboard lecture where he walks through how frontier LLMs are trained and served.

It's shocking how much you can deduce about what the labs are doing from a handful of equations, public API prices, and some chalk.

It’s a bit technical, but I encourage you to hang in there - it’s really worth it.

There are less than a handful of people who understand the full stack of AI, from chip design to model architecture, as well as Reiner. It was a real delight to learn from him.

Recommend watching this one on YouTube so you can see the chalkboard.

0:00:00 – How batch size affects token cost and speed
0:31:59 – How MoE models are laid out across GPU racks
0:47:02 – How pipeline parallelism spreads model layers across racks
1:03:27 – Why Ilya said, “As we now know, pipelining is not wise.”
1:18:49 – Because of RL, models may be 100x over-trained beyond Chinchilla-optimal
1:32:52 – Deducing long context memory costs from API pricing
2:03:52 – Convergent evolution between neural nets and cryptography

[Sladyn @SladynN]

@archiexzzz This is super interesting. I’ll try this out

[Sladyn @SladynN]

@_vmlops I need to feed this to Claude and make it train me

Studying how data moves in the network during inference

The movement of the KV cache across prefill and decode puts some strain on NICs

The world of networking has come up with a great distinction between front end nics and backend nics
