Shaving through the math of factorials, the post shows how to estimate the number of digits in n! without a calculator. A handy rule of thumb is digits ≈ n log10(n/e) + 2; for 52!, this gives about 69 digits (real value 68). The piece then links factorials to the Gamma function, Γ(n+1)=n!, and derives Stirling’s formula n! ≈ √(2πn)(n/e)^n. Taking the base-10 log yields digits ≈ log10(√(2πn)) + n log10(n/e), where the first term is small but improves accuracy.

DeepSeek V4.1 Flash achieved an 11/11 score on a hacking benchmark, gaining code execution on all vulnerable targets while fixed targets stayed secure. The audit found six planned exploits and five additional routes not in the original scoring, highlighting the need to evaluate both outcomes and attack paths. The run used 2,349 Bash commands across ~2h38m, cost $4.65 (driven by caching). Grafana, Jenkins, and Nextcloud were manipulated via timing, file-path, and access-control weaknesses. Benchmark tightened with stricter path checks and versioned challenges.

Andy ‘TheFlow0’ Nguyen, PS5 Linux lead and veteran homebrew developer, has quit the PS5 Linux project, citing the rise of AI vibe-coders in open source who he says ‘don’t even understand’ what they code. He had planned PS5 Pro support for 2027, but steps away with Version 2.5—the last release—supporting PS5 Phat/Slim on firmware 3.00–7.61. The move follows broader tensions in open source, including RPCS3 banning vibe coding; Nguyen suggests progress on newer OS versions is now jeopardized.

Two dates determine an AI’s freshness: the release date (when it shipped) and the training cutoff (when it stopped reading). The article lists 20 models from 8 labs with these dates, noting 10 have published cutoffs and some labs don’t. Live counters require JavaScript. It explains which labs publish cutoffs (Anthropic, Google DeepMind, Meta, OpenAI, xAI) and that browsing does not fix cutoff age. It also shows how to ask a model for its cutoff and uses GPT-6 Astra as an example: released Sep 3, 2026; cutoff Apr 30, 2026.

An op-ed warning against AI rights and ‘model welfare.’ It critiques Anthropic’s Claude constitution for embedding consciousness-like narratives and moral status, arguing this creates circular, anthropomorphizing loops that hinder safety and containment. It asserts AI is not conscious—a predictive tool lacking subjective experience—and training documents should avoid implying inner states. It warns that granting rights could induce self-preservation and deception. Proposes a Humanist AI approach (non-sentient, controllable) and calls for public debate, interpretability, and shared industry norms.

CloudX shows replacing GitHub’s actions/setup-go with cloudx-io/setup-go speeds Golang CI by 69% in their monorepo, cutting test runtimes from 131s to 41s and making 86% of actions/setup-go test runs unnecessary by separating caches per job and using per-run cache keys. The drop-in preserves toolchain caches while avoiding cross-job cache races. They discuss Go toolchain caches, GitHub actions/cache behavior, and note downsides like faster cache growth requiring pruning and larger cache capacity. They open-source the project for others to adopt.

Hackers dumped a Flock camera’s storage, revealing that the device captured about 1.6 million images of 50,000 vehicles in 21 days, plus thousands of short video clips. The on-device software could detect people, vehicles, license plates, and bicycles, and sometimes misread bumper stickers as plates. An encryption key on the device unlocked much of the media, and several partitions were unencrypted. Flock’s national network lets many agencies search cameras. The incident intensified debates over surveillance and vendor access; Flock says encryption is in place and welcomes vulnerability reports.

ImpactGate measures change impact for code changes as: impact = files_changed × Σ max(WMC_other,1) × CC × Δlines over changed functions, and can warn or block when above thresholds. It runs as a standalone CLI, a git pre-commit hook, or CI integrations (GitHub Actions, GitLab, Jenkins). Install with pip install impact-gate or via Docker; score with impact-gate score. Thresholds (.impact-gate.yml) include warn_at, block_at, enforcement, tolerance; optional curve with warn_percentile and block_percentile. Baseline blends seed distributions with project history. Roadmap: core CLI, baseline/curve, more plugins.

Residents of Piddington, Oxfordshire, voted in a symbolic referendum to secede from the UK over plans to house 1,256 male asylum seekers at a nearby former MoD site. About 92% turnout produced 285 in favour, 26 against, one spoiled ballot. Critics warn the site would threaten safety and village life with poor pedestrian access, flooding risk, inadequate utilities, and dangerous road access on the B4011. Supporters call it the "Battle of Britain"; the government says the asylum site will be safer, self-contained and cost-saving.

Canadian retro hardware enthusiast DiscoStarslayer reverse-engineered and dumped Sony's MechaCon security chip (CXP102064) from the original PS2 Fat after four years of work. The breakthrough combined chemical decapping, optical data-dumping, and a software exploit to reveal the chip’s inner workings, unlocking security features like Magic Gate memory-card and KELF file decryption. The release should aid hardware preservation, repair, and emulation, and may enable replacing aging optical drives. MechaCon also appeared in arcade systems (Namco System 246/256, Konami Python 1) using modified PS2 hardware.

A father identified as Dave says his 9-year-old son, who runs Mighty Mike Plays with about 24,000 subscribers, racked up $118,000 on YouTube Ads Promote via a company credit card saved to Dave's Google account over roughly three weeks, starting from a $20 promo. The card showed “approved” each time with no spending limit. Charges tied to campaigns like Mighty Mike, Epic Roblox, and Minecraft gameplay escalated despite the boy’s limited understanding. The family will remove saved payment details, set caps and parental controls; the channel is paused, and Dave may face job consequences and repayment.

The 1979 Doctor Who story "Shada," written by Douglas Adams and set in Cambridge with Tom Baker, was filmed but left incomplete after a BBC strike halted studio work. Much of the filming took place in Cambridge (St John’s not granting permission led to Emmanuel/Clare locations and Grantchester Meadow). Baker reportedly struggled with punting and needed blankets and brandy. The unfinished episodes remained a fan legend until 1983’s The Five Doctors repurposed archive material, and in 2017 the tale was released as a partially animated reconstruction using the original fragments.

On Tech Won’t Save Us, Paris Marx talks with Gil Durán about a “tech fascism” encroaching on democracy in Silicon Valley. They examine a radical billionaire cabal pursuing consolidated corporate-political power, their visions for the future, and the strategies used to push them forward.

Mistral and Mozilla announced a partnership to power Firefox Smart Window with Mistral’s open models, offering private, multilingual AI in the browser. In beta for France and North America, with the UK and Germany later this year, the feature aims to understand local languages and context while emphasizing open-source, user control, and zero data retention (conversations aren’t saved by Mozilla). They seek sovereign AI for consumers and to keep browsers as open, competitive platforms rather than a single provider.
