Precision in the high-frequency.
Capturing the split-second extension of a Rufous Hummingbird’s tongue isn't about luck; it’s about "System Alignment." My brain tracks the rapid-fire rhythm of the wings until the movement hits a geometric sweet spot.
In that micro-moment, the chaos of motion locks into a singular, sharp signal. My lens just acts as the final bridge between the intuition and the capture.

"In 1966, when seamstresses at the International Latex Corporation arrived at its new Apollo Suit shopfloor in Frederica, Delaware, they were essentially “taught to sew again from scratch.” And for good reason: Compared to the company’s bras and girdles, the craftsmanship needed to fashion a spacesuit was, in every sense, out of this world."

MegaTrain: Full Precision Training of 100B+ Parameter LLMs on a Single GPU
https://arxiv.org/abs/2604.05091
#HackerNews #MegaTrain #Full #Precision #Training #LLMs #Single #GPU #AI #Research
We present MegaTrain, a memory-centric system that efficiently trains 100B+ parameter large language models at full precision on a single GPU. Unlike traditional GPU-centric systems, MegaTrain stores parameters and optimizer states in host memory (CPU memory) and treats GPUs as transient compute engines. For each layer, we stream parameters in and compute gradients out, minimizing persistent device state. To battle the CPU-GPU bandwidth bottleneck, we adopt two key optimizations. 1) We introduce a pipelined double-buffered execution engine that overlaps parameter prefetching, computation, and gradient offloading across multiple CUDA streams, enabling continuous GPU execution. 2) We replace persistent autograd graphs with stateless layer templates, binding weights dynamically as they stream in, eliminating persistent graph metadata while providing flexibility in scheduling. On a single H200 GPU with 1.5TB host memory, MegaTrain reliably trains models up to 120B parameters. It also achieves 1.84$\times$ the training throughput of DeepSpeed ZeRO-3 with CPU offloading when training 14B models. MegaTrain also enables 7B model training with 512k token context on a single GH200.
Почему ваш персонаж телепортируется при высоком FPS: float precision в играх
Всем привет! Меня зовут Григорий Дядиченко, и я разрабатываю разные проекты на заказ. Сталкивались ли вы с ситуацией, когда персонаж в вашей игре начинает немного дёргаться, если поиграть достаточно долго? Или пуля иногда пролетает сквозь тонкую стену, хотя коллайдер на месте? Если да — добро пожаловать в мир проблем float precision. Сегодня хочется поговорить о том, почему тип float — при всей его повсеместности — может создавать тонкие и неочевидные баги в играх. Разберём, как он устроен, где именно он начинает врать, и что с этим делать. Если вам интересна эта тема — добро пожаловать под кат!

Blue Angels Glow
One of the highlights of Fleet Week was the precision flying team of the Navy Blue Angels. The Blue Angels put on a high speed areal acrobatic show that was second to none. They would fly in over the Golden Gate Bridge and proceed to dazzle the audiences with precision stunts that amazed and delighted the large crowd.
