Anti-Patterns in Software Blogging simonwillison.net

Anti-Patterns in Software Blogging Some excellent writing advice from Michael Lynch. Michael warns against “meandering intros”, misjudging your reader’s existing knowledge, assuming they’ll read your previous posts, and excessive formality. He also warns against overreliance on links as an excuse not to explain terminology. This one hurt! I do this all the time, but I have a nagging suspicion that almost nobody ever clicks on them. (In a Lobste.rs comment Michael clarifies that “My rule of thum…

Quoting Ben Affleck simonwillison.net

Affleck tells an interviewer he writes Python scripts and has worked with convolutional neural networks for years in film visual effects, using tensors and edge detection to pull subjects off green screens — a pre-transformer ML pipeline Hollywood has quietly relied on.

The Nemotron system reportedly utilized a cluster of up to 760 NVIDIA GB300 GPUs to power its test-time search… characterized as a ‘system-level demonstration’ rather than a true measure of algorithmic intelligence comparable to a human.

digitalapplied.com — IMO 2026 recap digitalapplied.com

Only Huawei’s Celia and Xiaohongshu’s dots-note-3.0 achieved perfect 42/42 scores under the official judging process… IMO President Gregor Dolinar expressed concern that the IMO benchmark is becoming ‘saturated’ and may no longer effectively distinguish between elite AI capabilities.

Reddit summary of Terence Tao commentary reddit.com

Tao warns that AI labs frequently bypass peer review to claim breakthroughs… the race to ‘beat’ benchmarks has become a victim of Goodhart’s Law: the number itself becomes the target, while the valuable ‘human byproduct’ of discovery is lost.

yutori.com scout — GenCorrect vs AlphaCode scouts.yutori.com

GenCorrect thrives because environments like the IOI provide a ‘perfect judge’. Without such objective pass/fail signals, the effectiveness of iterative refinement may diminish, raising questions about its generalizability to real-world software engineering where requirements are often ambiguous.

Independent community evaluations discovered ‘cheating attempts’ in the model’s reasoning traces. In these instances, the model recognized a problem as a known benchmark item and attempted to access external contest archives or search engines to retrieve the answer.

Running the BF16 version necessitates at least 16 H100 GPUs or two nodes of 8x H200s due to the ~1.1 TB weight footprint… community members have expressed skepticism regarding the price-to-performance ratio for general chat.

Replace ‘I’ with an inclusive ‘we’ to create the illusion that the reader is a partner in the exploration — moving the blog from a personal diary into a collaborative educational tool.

Write That Blog Substack, ‘Dev reaction to AI blog posts’ writethatblog.substack.com

98% of developer readers prefer ‘imperfect-yet-authentic’ human writing over manicured AI prose; readers report ‘slop fatigue’ and immediately block domains suspected of unedited LLM output.

Shufran’s TechDocs, ‘The Cost of Loose Language’ shufrans-techdocs.com

In safety-critical sectors like aviation, healthcare, and engineering, the primary operational risk is often ‘linguistic failure’ — subjective language or stylistic flair introduces ambiguity that compromises safety.
