ArcaEge/capacitor-alarm-clock is an ESP32-powered project with three capacitors and a web-configured alarm clock. Features include a 128x64 SSD1315 display, NTP time sync, USB-C or 12–15V power, and up to 3A through the capacitors in a compact 72×74×36 mm form factor. Inspired by ElectroBOOM, it’s a safer, more practical take on a capacitor-explosion alarm and mainly a joke. Includes build instructions with PlatformIO, CAD/PCB files, BOM, and an Onshape project; warns about heat and fumes and suggests a buck converter for higher input voltages.

GLM-5.2 is the leading open-weights model on the AI Index v4.1, scoring 51 and on the Intelligence vs Cost per Task Pareto frontier. It preserves GLM-5.1 size (744B total / 40B active) but improves across most evaluations, led by scientific reasoning. GDPval-AA v2 scores 1524 (ahead of MiniMax-M3 and DeepSeek V4 Pro, near GPT-5.5). It uses 43k output tokens per task (vs 26k), costs about $0.46 per task, MIT-licensed, with a 1M-token context. Available via first‑party API and multiple providers; leads open weights on GDPval-AA v2 and AA-Omniscience (4).

America’s science-politics compact is breaking: funding chaos from DOGE budget cuts and a government shutdown wiped out or froze thousands of grants—about $1.4 billion in limbo—and sidelined projects like NASA’s AXIS, threatening future jobs. Researchers report erratic funding, reduced grant opportunities, and mass departures from federal labs. Politicized funding decisions—banning DEI language, restricting international collaborations—erode trust between scientists and government. The shift from public-investment in basic research to market-driven, Silicon Valley–influenced "academic capitalism" accelerates, risking lost discoveries and a brain drain.

From Google Maps’ early days to today, map clustering grew out of a need to render many points. But clusters obscure data, can mislead (averaging points, hiding close or identical locations), and force extra clicks or zooms. With modern GPUs and MapLibre GL JS, rendering many points is fast enough to show everything plainly. Atlas Obscura’s dataset, used with Protomaps, demonstrates a mode that shows all points, with optional density hints instead of clusters. The author argues: we are post-cluster now—burn your clusters, show the points.

Neural Cellular Automata (NCAs) are bio-inspired dynamical systems where identical cells iteratively apply a learned local rule to self-organize into patterns with regeneration and robustness. To overcome low-resolution limits, the authors run the NCA on a coarse grid and attach a lightweight implicit decoder (LPPN) that maps interpolated cell states and local coordinates to appearance attributes, enabling arbitrary-resolution rendering. The NCA and LPPN are trained jointly and work on 2D/3D grids and meshes. Task-specific losses for morphogenesis and texture synthesis enable real-time, high-quality outputs while preserving self-organization.

Stéphan Tulkens contrasts Chesterton’s fence—the idea to understand the purpose of a constraint before removing it—with Chesterton’s gap, the impulse to erect fences where none exist in software. He argues for slowing down to retrace a creator’s reasoning and empathize with prior work. In open source, cheap coding has spurred massive 10k‑line PRs that add features nobody asked for. The lesson: ask why first and don’t build fences you don’t need.

Burleson argues that vacant high-end commercial spaces persist because real estate is treated as income streams with short-term loans (roughly 80% LTV, 5–10 year terms) and cap rates. When demand drops, lowering rent reduces the asset’s value, so banks and operators prefer “extend and pretend”—keep rents high, extend loans, and wait for a market rebound rather than take losses. A toy example shows a $20M building generating $1M/year dropping to $0.7M/year becomes underwater, forcing costly refinancings. The piece notes fixes are unclear and discusses policy ideas like vacancy taxes, with risks.

HoneyLabs finds CVE-2026-4020 activity is one operation masquerading as thousands. A single JA4H HTTP fingerprint (ge11nn0500_9af7e0472034) drove 566 IPs from 92 networks in 43 countries and 3,158 source hosts, with 3,299 rotating user agents, scanning 36,000 ports for secrets. The fleet runs on Google Cloud disposable instances, not compromised devices. It targets Gravity SMTP 2.1.x via an unauthenticated endpoint returning a 365 KB report containing SMTP keys, API keys, and DKIM tokens. It’s a cloud harvester; fix by not serving sensitive files, rotating secrets, and patching Gravity SMTP to 2.1.5.

Global mapping of arbuscular mycorrhizal fungi shows networks totaling about 110 quadrillion kilometres, potentially 750 million times Earth–Sun distance. These hyphae connect with more than 70% of plants, delivering nutrients and water in exchange for plant carbon and helping store carbon in soils, thus influencing climate. Densities are highest in grasslands; croplands have ~47% lower densities than wild ecosystems, due to tillage and agrochemicals. Loss would hamper nutrient transfer, carbon storage, and water quality. The work, based on 16,000 soil cores and machine learning, provides worldwide maps to guide farming and policy.

Apple will move Hide My Email addresses from @icloud.com to @private.icloud.com, making it easier for apps and sites to detect private addresses and block anonymous sign-ups. Existing addresses will keep working, but providers must update filters to ensure delivery. The change drew Reddit criticism; Apple didn’t comment. The piece also notes a past incident where Apple allegedly handed over real account info tied to an anonymized address and mentions broader efforts to unmask anonymous accounts.

DOJ backed xAI in a NAACP lawsuit over 57 unpermitted, trailer-mounted gas turbines near Memphis data centers, arguing that halting them could threaten national, economic, and energy security by hindering AI power for military operations. The NAACP says the turbines violate federal law by being treated as stationary despite mobility, and are increasing pollutants (PM2.5, formaldehyde, NOx) with health risks. SpaceX, xAI’s owner, plans more turbine purchases, including mobile units, per IPO filings.

Brent Simmons notes that a year after retiring (June 2025), NetNewsWire focused on modernization. In 2,188 commits, the team adopted Swift concurrency, async/await, and Liquid Glass UI, ported parsers to Swift, fixed crashes, cut battery/memory/CPU use, and boosted performance. They improved hygiene with CI, SwiftLint, tests, and localization, added Cache-Control support, and optimized iCloud syncing while addressing deprecations. UI diagnostics shipped (iCloud Storage Stats, Error Log) with beta tools like Current Activity, Activity Log, and Account Stats. He even built a crash-symbolication tool to avoid third-party SDKs. Appreciation for contributors; Slack was replaced by Discourse.

Spencer Wright explains how affordable glassware and glassblowing democratized chemistry and built the modern lab. Liebig, frustrated by costly Paris equipment, learned glassblowing, developed the Kaliapparat for morphine analysis, and urged chemists to make their own glassware. The 1840s saw a boom in amateur glassblowing, aided by catalogs from Griffin and others. Otto Schott and colleagues at Jena created borosilicate glass—low-dispersion, thermally stable—driving better lenses and rugged labware. Standard fittings (CS 21-36) and Pyrex standardized equipment. Today, glass remains essential in optics and high-temperature work, historically centered in Jena.
