@niewaznyanonim @PrzemekShura Propaganda też była, i nie tylko po ich stronie
Ale w sumie jaki byłby do tego bodziec? Jeśli chcą otrzymać jak najwięcej pomocy od innych to powinni udawać, że dostają po dupie

Rosja ruszyła do natarcia na 7 kierunkach — Trzeci Korpus informuje, że w zaledwie 4 godziny udaremnił największą próbę zmechanizowanej ofensywy FR! Armii FR nie udało się zająć ani miejscowości, ani pozycji.
Do próby przełamania na kierunku łymańsko-borowskim okupanci zaangażowali siły 1. Armii Pancernej oraz 20. Armii Ogólnowojskowej FR, ale wróg zaczął ponosić straty, zanim dojechał do linii starcia bojowego.
Straty przeciwnika w sprzęcie: 84 jednostki mototechniki, 11 BWP i transporterów opancerzonych oraz 3 czołgi. Trafiono system TOS „Suncepiok” i 5 dział. Zniszczono ponad 160 wrogich BSP. W ciągu doby brygady i pułki korpusu wyeliminowały 405 żołnierzy wroga: 288 to straty bezpowrotne (zabici), reszta to straty sanitarne (ranni).
„Przygotowywaliśmy się: na różnych kierunkach wypracowano działania obronne, każda brygada miała własny plan odparcia ataku. Korpus koordynował te działania — i w rezultacie na wszystkich kierunkach uderzenia zostały udaremnione” — generał brygady Andrij Biłećkyj.

This looks like ray marching with signed distance functions (SDFs). For every char position in the terminal grid, you cast a ray from the camera, step it through a procedural 3D world (math-defined terrain/caves/objects), find the nearest surface hit, then map depth/lighting/normal to an ASCII char for shading and structure. Real-time because it's CPU-efficient and low-res. Classic demoscene trick! What lib/language is it in?
English
My current pointless evening project (everyone should have one) is a real-time ASCII art engine where you can walk through procedural worlds and interact with your surroundings. Zero purpose to this, but fun to make!

Very often I want to temporarily disable a piece of code. I comment it out, but then I'm faced with a problem that since the code is never compiled it gets "stale". Some functions it uses may have changed and it is never type checked. So the next time I enable it, it doesn't compile and I spent a lot of time fixing it.
The solution I came up with so far is to "comment out" the code with the runtime `if (0)`. The code will never be executed, the optimizer will very like eliminate the code entirely, but before doing so the compiler will type check it, and will force me to fix it on the spot.

Poland’s finance minister says the country will match the UK’s living standards (PPP GDP per capita) within 5–6 years.
Finance Minister Andrzej Domański:
I accept this challenge: five–six years to catch up with the U.K. in price-adjusted GDP per capita.
In five years, we will catch up with Great Britain.

As I want to understand how @deepseek_ai v3.2 "fixed" GRPO, I break down the math behind the KL term.
What is in the original GRPO: the DS math/R1 papers borrowed what @johnschulman2 calls the k3 estimator. Starting from the true KL term (in green square, "the k1 estimator") that pushes the policy model closer to the reference model, there is a harmless second term (in yellow square) that has an expectation of 0 which means no bias is introduced.
The role of this second term is to offset the k1 estimator, so that while the expectation stays the same, the variance of the KL is much lower. This is because the second term (the "r-1") can be shown to negatively correlate with the KL term (the "logr").
The problem with GRPO: a true KL samples the rollouts from the policy model, but in reality, during several optimization steps, we are sampling from what is to the current step a previous policy. This makes GRPO off-policy and the KL term loses its meaning.
The fix: the new formula simply applies importance sampling, which basically reweights each sample so that the probability of it now equates it coming from the policy model. There is then no more bias in the KL estimation because each sample is weighted with the correct probability density.
The leftover: since the sampled rollouts still come from the previous policy model, the KL estimation is slightly high variance, but still there is no bias. As a result, training becomes more stable.
The paper is quite fascinating even after two weeks. I want to next have a deeper look at the DeepSeek Attention mechanism and potentially do some interp stuff on it!

major cheat code in life: be the one who reaches out. text first. call first. plan first. initialize first. most people wait to be chosen. be the chooser. connection requires initiative. friendship requires effort. love requires action. stop waiting to be picked. start picking. initiative is attractive.

@RpsAgainstTrump I have a theory that Putin will seek asylum in USA. He knows that he fucked up good and he wants to resign, but he knows that he will be hanged in Russia. So he will promise to Trump that he won't release the Epstein pdf shit that he has on Mr Orange in exchange for the shelter

Trump, caught on a hot mic about Putin: “I think he wants to make a deal for me. Do you understand? As crazy as it sounds.”

@a1zhang @OfirPress Cool work. How do you deal with the latency? Do you let it run or you make the prediction frame by frame ?

@OfirPress You can run your agents on these games here: github.com/alexzhang13/Vi…

Claude can play Pokemon, but can it play DOOM?
With a simple agent, we let VLMs play it, and found Sonnet 3.7 to get the furthest, finding the blue room!
Our VideoGameBench (twenty games from the 90s) and agent are open source so you can try it yourself now --> 🧵

If Hotz can actually pull this off and get the same performance via PyTorch as CUDA but without actually using CUDA, it opens the floodgates to alternative hardware (especially AMD’s), particularly on the inference side. There’s no fundamental reason why CUDA must remain a moat.
the tiny corp@__tinygrad__
What is tinygrad? tinygrad is a formalist project. It attempts to capture the full gamut of software 2.0 in a non leaky abstraction. The methods on Tensor class create a directed graph of immutable RISC UOps defining what the computation is. Tensor is a frontend, in addition we have an ONNX frontend and a PyTorch frontend. Whether you code in tinygrad, torch, or import ONNX models, it all boils down to the same very simple UOp graph, which you can see with VIZ=1 This graph contains nothing like matmul or conv, it's just movement ops, elementwise ops, and reduction ops. Seriously, try VIZ=1. Below that, there's a scheduler which breaks that graph up into kernels. Then we do more graph transforms on each kernel subgraph until we have code which can run on an accelerator. See the kernels with DEBUG=2. Then we have runtimes capable of running that code. For AMD, our runtime goes all the way to the physical hardware; we are mmaping the PCIe bus and peeking and poking it. It's all in Python, but it is fast because once you have the graph compiled, you are running the same graph over and over; just ringing a doorbell. The hope is that, similar to Linux and LLVM, we will prevent a major source of rent seeking in our AI future. By clearly and simply specifying the job, being able to precisely spec what is bought and sold, you can have a fair marketplace for compute. By the end of the year, we should be similar in speed on NVIDIA to the existing torch CUDA backend, except without CUDA. We will also have a test cloud up where you can run jobs from any of the three frontends. You don't want to rent a GPU per hour on a machine, you want to rent a couple FLOPS in a lambda function. That's what the OpenAI API is. Now offer it decoupled from the specific model.

Model size is such a crazy parameter, how do people even decide it
Is it intuitive or experimental 🤔

Tokenization issues still impact SOTA models in unexpected ways🤔
