MariaDB MDEV-38328 proposes promoting GitHub stars by adding a visible reminder in the server client prompt and in server logs. The change inserts an extra line like “Help others discover MariaDB. Star it on GitHub: https://github.com/MariaDB/server” into the client prompt and a Note line into logs, guarded by a maturity-level check and designed to be cherry-picked to older releases. The PR includes diffs to client/mysql.cc and sql/mysqld.cc, testing notes, and review discussions. It was merged into main in Jan 2026, though some discussions warned about potential log clutter.

Zitron contends that the AI “demand” is a bubble sustained by two labs, OpenAI and Anthropic, whose compute spend props most cloud revenues. He estimates 70%+ of AI revenues for Microsoft, Google, and Amazon come from these two, with hyperscalers backing them via backstops and private credit. Without them, hyperscalers’ AI revenues collapse; capex far outpaces real demand, risking unpaid data-center debt and restatements. The piece argues there is not broad AI demand, and the industry’s growth is largely circular financing.

West Coast Stat Views critiques the AI-economic bubble and the shift to open-weight models threatening proprietary frontier AI firms. It argues that outsized capital expenditure, mounting debt, and the prospect of commoditized AI could undermine profitable pricing and trigger a debt crisis amid regulatory risks. It cites Chinese open-weight success (Moonshot AI’s K3) and US labs switching to open-weight, creating tense dynamics for OpenAI, Anthropic, and Nvidia, under the banner: It's not a fear of AI communism; it's a fear of competitive market capitalism.

Ken Shirriff details the MMI 5300 PROM from the early 1970s, a 1,024-bit bipolar memory storing 256 4‑bit words. Data sits in a 33×33 array of diodes and Nichrome fuses; intact fuses represent 1s, blown fuses 0s. Addressing uses A0–A7 to select a word via a 32-column decoder and four outputs through a DTL/multiplexer path. Programming requires precise high‑voltage pulses (27V to blow fuses; about 20V on the output) and testing uses extra fuse rows/columns for yield checks. Cost was ~$70 in 1971; later PROMs evolved to EPROM/EEPROM and then flash.

Apple has filed for a preliminary injunction and expedited discovery in its trade secrets case against OpenAI, alleging that more former Apple employees may have stolen confidential data and aided OpenAI in developing products based on Apple technology. The filing adds that 11 other former Apple staff beyond Chang Liu and Tang Yew Tan were involved or witnesses, including meetings with Liu and Yu-Ting Peng and a former employee who took screenshots of Apple documents. It also notes ex-Apple workers at OpenAI sought to return company devices. OpenAI denies wrongdoing and calls Apple’s claims false.

Dotenv started as a simple KEY=value delivery mechanism but grew into the project’s configuration schema and secret store. Values are strings, no schema, no guarantees about required vs optional, production vs development, or access control. Proliferating .env files create brittle deployment and risk leaking secrets. SecretSpec separates the declared needs from storage and delivery: a TOML declaration states what is required; providers hold and protect values; deterministic resolution with scopes, profiles, and migration helpers lets apps run with a consistent environment from startup. The aim: remove secrets from environment variables and keep .env only for ordinary local settings.

Adform, a major online ads provider, was hacked and began serving malicious ads on July 27. The firm handles about 1.5 billion ads daily. Security researcher Kevin Beaumont says the loaded ad code was altered to run in victims’ browsers, replacing the clipboard’s crypto wallet address with one controlled by the attacker every three seconds, enabling crypto theft when pasted. Adform is investigating whether other data, such as visited websites, were accessed; numbers affected are unknown. The incident underscores the usefulness of ad blockers to prevent malware delivered via ads.

Germany logged a historic 12 billion kWh of solar fed into the public grid in July 2026, per IWR from ENTSO-E data (on-site use not included). Midday output topped 40,000 MW, displacing coal and gas and signaling photovoltaics as a core electricity source. Growth stems from two decades of investment by homeowners, farmers, and SMEs. The EEG differential-cost mechanism funds the difference between market price and tariff; legacy 2010–2013 contracts (30–40 euro cents/kWh) expire 2030–2033, reducing future EEG costs.

Researchers define an inclusive skin-tone color space and a practical color picker to support character creators and digital art. They label RGB colors, apply PCA to transform data into XYZ space, then fit spherical equations to map to a TUV-like space. The color picker uses three axes T, U, V derived from PCA, with R² controlling sphere radius and variation. They provide sample Python/JS implementations and discuss limitations due to biology, lighting, and display. The project emphasizes not being authoritative, invites feedback, and outlines future refinements and potential extensions to model conditions and improvements.

Casey Muratori argues that many “clean code” guidelines—polymorphism, DRY, small single-purpose functions, separating data and behavior—hurt performance. He compares a shape hierarchy using virtual Area calls to flat, switch-based or table-driven approaches. Tests show ~35 cycles per shape for the class-based version; switches can drop to ~24; a table-driven approach reaches 3.0–3.5 cycles per shape (10x+ faster). Adding a second property (corner count) worsens clean-code variants to 20–25x slower vs non-clean. Conclusion: performance-aware programming should trump rigid clean-code rules.

Max Glenister rebuilt four years of Wordle data from WhatsApp shares after NYT migration and device upgrades broke local history. He parsed a chat export with regex to extract date, puzzle number, guesses and win/loss, deduplicated by puzzle, and produced a CSV. The 1,552 games (Jan 2022–mid-2025) yield 99.42% wins and streaks of 278/107. Opening greens cut average from 4.11 to 3.79; sharing patterns differ by weekday and hour; monthly guesses rise as words get reused. Nine tough words: fewer, hound, scarf, jolly, rover, sixth, blaze, ready, carom. NYT migration and a legacy key explain gaps.

Explains the 1582 switch from Julian to Gregorian that skipped October 5–14, 1582 to correct drift. Highlights how languages handle impossible dates: Ruby rejects DateTime(1582,10,5); Python and Perl apparently allow creating ‘Gregorian’ dates in that gap. The author concludes that two of three languages permit such dates, signaling gaps in date-time correctness and the need for explicit checks to forbid impossible dates. Also notes historical quirks: other regions adopted later, and tools like ncal can model country-specific corrections.
