PostgreSQL on AWS benchmarks PostgreSQL performance across AWS EC2 instances (arm64 Graviton and x86-64) with gp3 storage, for 1–50 GB datasets under a 90% read / 10% write, 32-way concurrency in us-east-1, aiming for 33,000 RPS. A cost-performance frontier shows which configs meet the target; the cheapest 1 GB config is m8g.large gp3-baseline (~$82/mo, 45,515 RPS). Arm64 often offers best value; c8i.large reaches 52,203 RPS. The full 52-config table reports RPS, latency, and cost data for filtering and comparison.

EU Parliament advanced a renewed extension of “Chat Control,” approving an urgency motion to reintroduce the transitional regulation that expired in April, allowing tech firms to voluntarily search private chats for child sexual abuse material. The move, 331-304 with 11 abstentions, enables a plenary vote Thursday before summer break. Critics call it a procedural trick undermining rules; supporters cite preventing a regulatory gap and that reports would otherwise miss abuse material. Privacy advocates warn of mass surveillance and pressure toward a permanent Chat Control 2.0.

Sodium-ion batteries could cut cost and diversify battery supply for EVs and grid storage. CATL-backed cells power Changan’s Nevo AO6, signaling mass production of sodium-ion EVs. Although heavier with lower energy density than lithium, recent advances push sodium-ion density toward 175 Wh/kg, with costs dropping as production scales. Benefits include lower fire risk and better cold performance, since sodium moves more reliably at low temperatures; CATL says the pack retains about 90% capacity at -40°C and did not ignite in a halved test. Sodium could reduce reliance on lithium mining, expanding use in EVs, cargo vehicles, and grid storage.

Explains asymmetric fences: a light, compiler-level barrier on the fast path and a heavy, OS-assisted barrier on the slow path. In Folly, asymmetric_light uses an asm memory clobber or _ReadWriteBarrier; asymmetric_heavy uses membarrier() (MEMBARRIER_CMD_PRIVATE_EXPEDITED) with a fast path for single-thread or mm_users==1. The post details how membarrier orders memory across threads via IPIs and smp_mb, and why a naive transitive model fails, prompting updated C++ wording (P1202) that confines ordering to the single total order on seq_cst operations. Includes discussions with David Goldblatt.

Dua Lipa has opened the Manifesto Library, a collection of banned and censored books, inside Porto’s Livraria Lello as part of the BABELL – City of Books festival. The library, roughly 100 titles, champions works that challenge power, censorship, and oppression, with themes of race, sexuality, and LGBTQIA+ issues. Notable titles include The Handmaid’s Tale and works by Salman Rushdie and Olga Tokarczuk. Linked to Lipa’s Service95 Book Club, it aims to defend reading as a “technology of freedom.” Lipa will also curate the London Literature Festival in 2026.

98% sounds strong but isn’t enough for accessibility or reliability. The piece argues that serving 98% of users still excludes 2% (or more) in real-world audiences, with examples from food safety and browser features. Even so‑called “widely supported” features can fail for a significant minority (e.g., 30% of a client’s visitors). True robustness means gracefully handling edge cases, not optimizing for the majority; inclusive design is urged.

Henry Begler maps Bob Dylan’s late-career rebirth and mythmaking. After a 1997 histoplasma scare and Time Out of Mind’s moody, enveloping sound, Dylan launched the Never-Ending Tour, reviving his relevance with Not Dark Yet and other mortality songs. The 2000s brought Love and Theft and Modern Times, rich with Whitman, Twain, and Confederate echoes, plus Masked and Anonymous. Shadows in the Night and Triplicate revisited the Great American Songbook, refining his weathered voice. Rough and Rowdy Ways, especially Murder Most Foul, turned to memory and American myth, presenting Dylan as the last great traditionalist who keeps moving on.

Het Tulp Fonds, in 2025 door OCW en NWO opgericht, biedt internationale toponderzoekers de kans om hun onderzoek in Nederland voort te zetten. Het fonds heeft totaal 50 miljoen euro beschikbaar en verwelkomt 34 wetenschappers die vanuit universiteiten, umc’s en hogescholen naar Nederland komen (veel uit de VS; sommigen keren terug uit Europa/andere regio’s). Per onderzoeker kan een instelling maximaal 1 miljoen euro ontvangen over vijf jaar, voor fundamenteel tot toegepast onderzoek. Doel: versterking van de Nederlandse en Europese wetenschap en innovatie op gebieden als AI, quantum, vaccins, gezondheid, klimaat en democratie; meer toekenningen volgen in 2027.

CipherCue analyzed apex and www records for 19,450 European companies across the UK, Netherlands, Italy, Spain, France, Germany, and Poland to identify the internet-facing vendor serving the main website. US-headquartered vendors front a majority or plurality of sites in most markets, with UK 67.5% and NL 53.6%; Italy, Spain, and France around 44–48%; Germany 31.0% and Poland 18.8% (domestic hosting strongest in DE and PL). Cloudflare is the single largest internet-facing vendor in all seven markets. The study measures the vendor answering the DNS query, not hosting origin.

Germany attracts skilled workers but struggles to retain them. An IAB survey found emigration driven by family reasons, discrimination, bureaucracy, housing, and language. About 60% of emigrants return home; 40% move to other EU countries. Emigrants tend to be younger, with weaker German and stronger English. Key complaints: lengthy, opaque processing for naturalization, residence, visas, and recognition of foreign qualifications; high fees; poor career support. Language acquisition support is crucial; English programs alone are not enough. Demand remains in care work; policymakers are pursuing a centralized 'Work and Stay' approach, but staff shortages and uneven digitization slow progress.

An image-filled look at NASA/NACA wind tunnels from the 1920s to the 1990s, showing Langley and Ames facilities used to test aircraft and spacecraft under high-speed, turbulent, and specialized conditions (transonic, icing, ionization). It highlights giant tunnels like Ames’ 80x120 ft chamber, the era of numerous facilities, and their consolidation and demolition in the 1990s as computer simulations rose. The collection features iconic tests (Mercury capsule, X-15, space-shuttle ionization tests, Avrocar) and notes Mary Jackson’s path to NASA’s first Black female engineer.

Stephen Wolfram visited Leibniz's Hanover archive, exploring how Leibniz aimed to build a universal, calculable architecture of knowledge—scientia generalis, lingua philosophica, characteristica universalis, calculus ratiocinator—and how that vision foreshadowed modern computation. He notes Leibniz's notation (Π as an equals sign, overlines, the integral sign), early ideas of encoding attributes with numbers, and a fascination with binary and the I Ching. Leibniz built a mechanical calculator and dreamed of a universal calculator, but practical limits impeded progress. Wolfram argues Leibniz linked philosophy and computation, foreshadowing our programmable future.

An overview of The Art of Computer Programming (TAOCP) by Donald E. Knuth, including a newsletter, recognition as a leading physical-science monograph, and publication logistics. It explains downloadable PDF indexes, warns against inferior non-PDF editions (with replacement promises), and lists the volumes and fascicles (Vols 1–4B, 5 in preparation) plus translations. It outlines MMIX replacing the MIX, beta fascicles, errata/addenda for Volumes 1–4, and future volumes (Vols 6–7) contingent on relevance. It invites reader feedback, notes rewards for reporting errors, and provides contact details.
