Shayon Mukherjee details a tiny FUSE filesystem, magicfs, mounted at /magic with a private store (metadata.json and blobs/). It implements a simple inode- and name-based directory, with file contents as blobs and metadata mapping names to inodes. Reads go through the VFS and FUSE; writes stage in memory and commit as new blobs with atomic metadata updates. It notes TTL-based caching and the fsync/flush distinction. Shortcomings include no journal, one directory, no locking or real permissions, and no recovery; possible improvements are chunking, garbage collection, and a transaction log.

Sophia Wood introduces a playful language for composing clocks on a canvas. The system uses a vocabulary of types—vectors, modified vectors, scalars, glyphs, and habitats—assembled in a Loom to produce a clock via a Weave that compiles to a self-contained p5.js sketch. Time is encoded as vectors (raven hours, crow minutes, mag-pi seconds) and combined with scalar operations; glyphs render the scene and habitats paint the canvas. The clock is tunable (cycles per day, hours per cycle, breath, theme) and exportable as offline-ready HTML. Built in a Recurse Center batch using Svelte, TypeScript, Vite, p5.js.

An article about the last surviving Japanese Porsche 912 police car. In the 1960s Japan had four 912s customized for police use; this car operated in Kanagawa from 1968–1973 on the Daisan Keihin and Tomei Expressways, clocking over 155,000 km and helping stop a speeder at 178 km/h. After retirement due to engine failure it sat at a police academy for 26 years, deteriorated, and was sold to a scrapyard in 1999 before being recovered after six months of negotiations. Includes archival photos.

Curl project pauses vulnerability reports in July 2026 for 'summer of bliss': HackerOne submissions paused July 1–Aug 3, 2026; security email ignored; issues to be reported later. Release 8.22.0 delayed to Sept 2, 2026 to allow rest. GitHub issues/pulls stay open. Paid support unaffected. Encourages others to participate and take care of themselves.

CrowdScience investigates why paper holds creases so well. Haruka’s origami journey with a cloth napkin sparks a deeper look at paper structure. The show visits Frogmore Paper Mill where Dr Steven Mann explains papermaking and the chemistry behind foldability. Host Caroline Steel and experts compare different paper types under a microscope, with Prof. Bill Sampson describing why creases form. The episode also features Prof. Tomohiro Tachi and his Origamizer, illustrating the complexity of paper folding.

Mark Horrell traces Cerro Torre’s half‑century of controversy over climbing ethics. Cesare Maestri’s disputed 1959 ascent with Toni Egger, plus evidence on Torre Egger, fuels ongoing doubt. Maestri’s 1970 Compressor Route—bolts drilled up the face—shocks purists. The first undisputed ascent came in 1974 (Ferrari team). In 2012 Hayden Kennedy and Jason Kruk climbed it by “fair means,” removing about 125 bolts; they were arrested, sparking a heated debate on bolt use and necessity. Shortly after, David Lama free climbed the Compressor Route, renewing the mountain’s legend as “set free.”

An exploration of Emacs’ lesser-known, stock features—batteries included—that boost daily editing and navigation. The author tours practical but under-reported tools, from dictionary-tooltip-mode, wildcard-friendly find-file/dired, and ffap-menu for URIs, to lightweight diff with compare-windows and dired-compare-directories, highlight-changes-mode, and smarter backups via VC. The piece also covers the apropos family, jump-to-source with find-function-on-key, editing macros with kmacro-edit-lossage, word-syntax tweaks (subword/superword), image manipulation, visibility controls (visible-mode, isearch-toggle-invisible), rulers, refill, scrolling aids, and undelete-frame. Aimed at quick mastery and continual discovery.

Modern CPUs are fast; the bottleneck is memory. The Memory Wall arises because DRAM latency grows faster than CPU speed. DRAM reads involve row activation, precharge, and column access; non-sequential access causes costly misses. Caches (L1/L2/L3) bridge the gap, but performance collapses when data isn’t in cache. Aletheia experiments, including a stride scan, reveal a sharp cliff at stride 64: each access hits a new cache line, yielding a cache-miss-dominated, memory-bound workload. The Roofline model shows programs are often memory-bound; optimize data movement, not just computation.

George Michaelson's APNIC blog commemorates 21 years of the eight fallacies of distributed computing and explains each: the network is reliable; latency is zero; bandwidth is infinite; the network is secure; topology doesn’t change; there is one administrator; transport cost is zero; the network is homogeneous. Tracing origins to Sun founders (Joy, Lyon; Deutsch; Gosling), the piece argues these are persistent misbeliefs shaping software design. It highlights real-world constraints—loss, delay, jitter, changing topologies, multiple admins, and nonzero costs—and urges engineers to design with these realities in mind.

Windows Central reports that Windows 11's mandatory Microsoft account during setup remains a key user grievance. A Reddit thread shows users pushing for a local account option at OOBE, arguing this is about control and privacy, not just bypassing restrictions. The discussion notes Microsoft ties accounts to security features like BitLocker and cloud integration, and some inside Microsoft have urged reconsideration, but no commitment has been made. Windows 11 users want a choice and clearer explanations of how account decisions affect encryption and recovery keys; a compromise could be a default online account with a local option.

Researchers sequenced 53 Lanmaoa specimens and revised the genus to 17 species, describing Lanmaoa fallax and Lanmaoa carbonilivor; Lanmaoa asiatica, though edible and widely eaten, carries no known psilocybin or ibotenic acid genes and lacks any recognized hallucinogenic chemistry. Yet regional reports describe vivid Lilliputian hallucinations after eating undercooked jian shou qing, suggesting an unknown biosynthetic pathway in boletes. This could represent a third family of psychoactive mushrooms, with effects seen globally, not yet explained by known compounds.

Pakistan, mediating between the US and Iran, says a peace deal has been reached to end military operations on all fronts, including Lebanon, with signing expected Friday in Switzerland. Trump celebrates, saying “oil will flow” as the Strait of Hormuz would reopen. Iranian state media cites a 14-point memorandum outlining ceasefires, sanctions relief, and reopening Hormuz under Iranian arrangements, though details remain unconfirmed. UK, Germany, Qatar and others welcomed the breakthrough and urged rapid, verifiable implementation and that Iran must not obtain a nuclear weapon.

Food authenticity is a modern illusion driven by gatekeeping and media. Using carbonara, the piece shows how a strict “authentic” version crystallized only recently; earlier Italian recipes varied with cream, different cheeses, and substitutions. Global media and nostalgia fuel purist debates even as dishes migrate and hybridize. The Singaporean Hainanese chicken rice example traces diaspora influence on technique, condiments, and even rice color, while keeping historical roots. The author argues we should abandon purity policing and instead discuss how recipes travel, evolve, and reflect history and context.

The post shows epubcheck isn’t enough for Kobo devices because Kobo uses Adobe RMSDK for rendering. Even with a passing epubcheck, Kobo may report a book as 'corrupted' due to RMSDK’s obsolete CSS support. Debugging reveals the culprit: a valid CSS line .copyright img { max-width: min(150px, 30vw); } that RMSDK cannot parse. Replacing with max-width: 150px fixes it. EPUB is open, but RMSDK’s age causes silent failures; publishers must test against RMSDK-powered Kobo readers.

From Dumey's 1956 hashing concept—mapping data to memory using base-37 digits and modulo with a prime—to store words like BOX at specific addresses, the post explains that indexing and hashing are essentially the same idea. The term hash grew into cryptography, defined by Diffie and Hellman (1976) as a one-way function that protects data by irreversibility. Hashes resist reversing plain text, enabling secure password storage, digital signatures, and blockchain. Security rests on preimage resistance and collision resistance; adversaries may exploit high-degree polynomials or discrete exponentiation over finite fields. Quantum computing threatens, prompting post-quantum cryptography.
