Dự án "Rosetta Stone" xây dựng HTTP/1.1 client hiệu suất cao từ đầu bằng C, C++, Rust, Python. Bài viết so sánh kiến trúc, tối ưu hóa (zero-copy, writev, Unix sockets) và kết quả benchmark. Client tự viết đạt hiệu năng đỉnh cao, nhiều khi vượt thư viện có sẵn. Mỗi ngôn ngữ thể hiện triết lý riêng về an toàn, tốc độ và trải nghiệm phát triển.

SimpleBench cho GPT‑5.2 và GPT‑5.2 Pro đánh giá thấp hơn GPT‑5. Hiệu năng giảm: các phiên bản mới hơn nhận điểm thấp hơn so với GPT‑5, như báo trên Simple‑Bench leaderboard. Thông tin từ lmcouncil.ai/benchmarks (đánh giá trên Reddit).

Here’s some context for #GHULbenchmark:
Most tools show synthetic numbers — #GHUL measures real heat, real load, real sensors. Hardware doesn’t die from FPS; it dies from thermals, VRAM hotspots, and PSUs begging for mercy. 🔥💀
Fun fact from RDNA4 testing: the new “silent” fan feature is a silent killer. VRAM hits 90°C, hotspot follows, fans chill at 46% (BIOS-enforced).
GHUL would cook the card instantly if I hadn’t added emergency shutdowns.
Uploads aren’t required — real nerds test locally first, then send a PR when something explodes or a sensor speaks folklore. 😄
AMD & NVIDIA supported; Intel ARC is next.
Own an ARC card? Congrats, you’re volunteered.

🚀 GHULbenchmark v0.3 is here!
A Linux-native hardware torture & analysis suite — built because nothing out there did what it should.
Same reason Linux exists.
Same reason Git exists.
If the tools suck, we write better ones. GNU-style. 🐐
🔥 #Hellfire Stress Tests (CPU/GPU/RAM/Cooler)
🧠 Sensor autodiscovery (--dump-layout)
💀 GPU Diagnostic Mode
📈 Upload system coming soon — fake scores will die screaming
🐧 #AMD & #NVIDIA supported — Intel #ARC enters the arena next
#GHUL #benchmark
Built FOR Linux.
Built ON Linux.
Built BECAUSE Linux.

Microbenchmarking NVIDIA’s Blackwell Architecture: An in-depth Architectural Analysis
Interesting presentation at #FF2025 by Mike Trizna @miketrizna.bsky.social and Richard Naples on #Benchmarking ... using the example of historical botanical text from Smithsonian-published work ...
... which is very much the Smithsonian complement to the (yet undigitised) collection of botanical drawings and paintings published by the Royal Botanic Gardens at Kew recently:
https://press.uchicago.edu/ucp/books/book/distributed/F/bo265674343.html

For the first time, Kew’s recovered collections of Indian botanical art are brought together with the remarkable stories of the artists who painted them, the colonial context in which they were made, and their essential role in the development of botanical knowledge. Featuring a representative selection of one hundred artworks from the previously fractured, uncatalogued, and largely inaccessible collection of over seven thousand Indian illustrations in Kew’s archives, Flora Indica foregrounds the vital role of Indian artists in helping to advance both scientific knowledge and the aesthetics of botanical art. The botanical watercolors, created between 1790 and 1850, were commissioned by British botanists, many of whom were employed by the East India Company to document India’s rich plant diversity. The text by leading expert Henry Noltie reveals the lost stories of how these illustrations came to be, exploring the work of twenty Indian artists from eleven collections, with nineteen named individuals and thirty previously unseen illustrations. Noltie’s extensive research into these hidden histories features plants native to South Asia alongside exotics introduced from the then-emerging international network of botanical gardens, taking readers on a journey that explores the environments in which these master artists worked. The style of the works represents a unique fusion of traditional Indian artistry and techniques with botanists’ demands for naturalism and scientific specificity from an Indo-British perspective. Presented with a foreword by art historian William Dalrymple, Flora Indica illuminates Kew’s beautiful Indian botanical art collection, through which readers are invited to discover the important lost histories of Indian botanical art from the age of empire.
