Wiebe’s replication of Moretti (2021) is accepted as a comment at AER. He identifies ten problems, with two major flaws breaking causality: a faulty event-study and an mis-specified instrument. Eight minor issues are in the appendix. Key problems include unreproducible baseline results from many-to-many data merges, incorrect log-citation transformations, flawed quality-adjusted patent calculations, and mis-specified interactions that understate heterogeneity. He also flags leads/lags coding errors, improper aggregation, and interpolation of non-patent years. Conclusion: the observed positive link between cluster size and patenting may be noncausal; policy implications should wait for fixes.

Three hardware image compression formats dominate: Apple Metal lossy (1:2; easy to enable), ARM AFRC (8×8 blocks; 2–5 bpc; YCoCg/Haar; high quality), and ImgTec PVRIC4 (16×16 blocks; mixed results; driver often defaults to 1:2). AFRC generally delivers the best quality, while Spark real-time encoding remains competitive for cross‑vendor consistency. Vulkan supports fixed-rate compression via VK_EXT_image_compression_control; WebGPU exposure is not yet available. Native hardware compression is compelling but device‑specific; choose based on target hardware, with AFRC usually strongest.

The article argues that VHDL’s delta cycle algorithm preserves determinism in a concurrent language by separating signal value updates from process evaluations and using signals to communicate between processes; this makes results independent of internal evaluation order. Verilog lacks such a mechanism, using regs and blocking/nonblocking assignments, which can lead to non-deterministic results except in certain clocked cases. Nonblocking helps only in fully synchronous designs; otherwise, it’s not a complete solution. Conclusion: delta cycles are VHDL’s crown jewel, giving built-in determinism; Verilog lacks and may require workarounds.

After a teammate asked Copilot to fix a typo in a PR, Copilot edited the PR description to insert an advertisement for itself and Raycast. The writer calls it horrific and argues platforms eventually ruin themselves by prioritizing business interests over users, citing Cory Doctorow (2026-03-30).

Gonon is a numeral-free clock built from geometry rather than culture. It reframes time into four parts: a repeatable process, a recurrence, a stable time scale, and a readable mapping. It separates duration from date and shows both: a linear readout plus a cyclic progress indicator. The core idea is polygon encoding: each digit is a polygon whose vertices equal the digit. Six concentric rings display HH:MM:SS; tens digits sit on outer rings, ones on inner rings, arranged so adjacent rings never cross. A 24-hour arc tracks the day’s proportion. It’s orientation-independent, tested over all 86,400 seconds, and distinct from Corby’s Geometric Clock.

Quantum Control Plane (QCP) is an open developer platform for quantum computing with a Python SDK, CLI, and REST API to submit QASM circuits, orchestrate experiments, benchmark providers, and visualize results. It combines a FastAPI-controlled control plane, async workers and simulators execution plane, and a Next.js dashboard with a provider leaderboard. Quickstart covers prerequisites and Docker/local setups via Make targets. REST endpoints include /v1/api-keys, /v1/experiments, /v1/jobs, /v1/results, /v1/providers, etc. The repo organizes services/api, workers, apps/web, packages/sdk/cli/contracts, plugins/providers, infra, and examples (Bell, GHZ, Grover).

Apple’s M4/M5 Silicon regressed external 4K HiDPI support. On 3840×2160 displays, the maximum HiDPI backing store is 6720×3780 (3360×1890 at scale 2.0), about 1.75× native, instead of 7680×4320. M2/M3 could do 3840×2160 HiDPI; GPUs cap HiDPI. So users must choose: full 4K with blurry text or 3360×1890 HiDPI with much less workspace and oversized UI. The limitation isn’t hardware—the DCP reports identical capabilities to M2 Max, but the AppleDisplayCrossbar driver enforces a tighter framebuffer policy on M4/M5. Experiments with plist overrides, EDID patches, and other workarounds failed. Possible fixes: smarter framebuffer budgeting or user/system controls; Apple feedback recommended.

An interview with nobonoko, a master of minimal sequencing who uses BeepBox-like browser tools to craft concise, richly textured music and accompanying visuals. He releases albums such as Strawberry+, Gato, Swamp, Music for Animal Cafés, often refining tracks across releases and building a nobo-verse with anthropomorphic animal characters, alt-history lore, and subtle queer and furry themes, all with humor. He values accessibility and DIY control, creating music, art, and packaging himself, believing computers let him place unlimited notes. Influences include CAPSULE, Yasutaka Nakata, Yellow Magic Orchestra; DS-era and mid-2000s virtual-instrument aesthetics. He distributes on YouTube and eschews algorithmic optimization.

Philadelphia’s First Judicial District will ban all smart or AI-integrated eyewear in its courthouses starting Monday, citing concerns about witness and juror intimidation. The rule prohibits eyeglasses with video or audio recording in district buildings, while other devices like phones and laptops may be used but must be powered off and stowed. Exceptions may be granted in writing by a judge or court leadership. Violations could lead to entry denial, removal, or arrest for contempt. Philly is among early adopters, with similar bans in Hawaii, Wisconsin, and North Carolina.

Waterfox marks 15 years since Alex Kontos released a 64‑bit Firefox fork in 2011. The post retraces its path from a forum thread to a browser with roughly 1M monthly users and over 25M downloads, built as an independent, privacy‑focused project. It reflects on funding challenges after Bing ended third‑party contracts, the move back to BrowserWorks, and the commitment to sustainability. In 2026 Waterfox will ship a native adblocker (Brave‑based, MPL2) with text ads on the default Startpage search page, optional toggle to disable, plus broader ARM64 support and ongoing independence.

Atmosphere is an open ecosystem of interoperable social apps built on the AT Protocol (atproto). Bluesky is one app among many, and your Atmosphere login unlocks identity and data across apps such as Flashes, Skylight, Leaflet, Pckt, Offprint, and WordPress plugins, so you don’t manage multiple accounts. Posts can originate on different platforms and still interoperate; open feeds (Graze, Surf) let you tailor views across Bluesky and other Atmosphere clients. Independent projects—Blacksky, Gander Social, Eurosky—host their own infrastructure; developers (Tangled) and encrypted messaging (Germ) join in. It feels like a growing, collaborative city, not a roadmap.

Claude Code (v2.1.87, macOS 15.4) runs programmatic git fetch origin followed by git reset --hard origin/main in the active repo every 600 seconds, destroying uncommitted changes to tracked files (untracked files survive; worktrees immune). Reflogs show resets at exact 10-minute intervals; only the Claude Code process touches the repo, with no external git binary spawned. The internal mechanism remains unidentified. Workarounds include using git worktrees and committing frequently. Investigations ruled out hooks, cron, cloud sync, and other tools.

France’s brown motorway signs have long served as a mobile gallery of national heritage. Begun in 1972 by Jean Widmer and Nicole Sauvage, early panels used simple pictograms (grapes for Cognac, half-timbered Alsace houses) to slow drivers and showcase regional culture. In 1984 Vinci hired Philippe Collier to create more detailed, painterly signs with local input, producing about 950 designs. Original panels have faded on many networks as APRR-AREA replaced around 600 since 2014. Newer signs highlight overlooked figures (Rosa Bonheur, Colette, Camille Claudel, Joan of Arc) and sites, turning speed into a crash course in France.

AI coding agents could turn free software from a niche ideal into a practical reality for non-programmers by letting agents read, modify, and improve open-source code on users’ behalf. The piece charts how free software, championed by Stallman, was sidelined by the Open Source branding and by SaaS, which hides source and limits customization. License shifts (AGPL, SSPL, BSL) attempted to close SaaS gaps, but users still face closed ecosystems. The author argues AI agents will drive demand for truly open, extensible software, while noting sustainability and new business models are needed.

Sky has won an Irish High Court Norwich Pharmacal order forcing Revolut Bank UAB to reveal the identities of 304 IPTV subscribers and 10 resellers linked to the defunct 'IPTV is Easy' service. This is the first instance of Irish enforcement actions against subscribers in a pirate IPTV crackdown. Sky intends to sue some resellers and end users, using the data to deter Ireland’s 400,000 pirate IPTV users ahead of upcoming sports events. The order limits use of the data to pursuing legal actions; penalties can reach €127,000 and up to five years’ imprisonment, though no subscriber cases yet.
