The Document Foundation, LibreOffice’s nonprofit, ousted about 30 Collabora-affiliated members to protect its nonprofit status, prompting Collabora to pivot toward a trimmed Collabora Office. The article explains TDF’s governance as a German Stiftung with a board, membership committee, and directors; Collabora has long been LibreOffice’s largest external contributor. Audits from 2023–24 flagged potential nonprofit-law issues tied to past tenders and trademark use, fueling disputes that produced non-renewals and delayed elections. New bylaws would force resignations of members tied to disputing entities. The piece weighs governance, Gemeinnützigkeit, conflicts of interest, and possible paths forward (reform, mediation, or splitting the ecosystem).

US will revoke passports of thousands of parents who owe child support, starting with those in arrears of $100,000 or more (about 2,700 holders). The policy will expand to >$2,500 in unpaid support, potentially many more. Previously tied to passport renewals, revocation now applies to all past-due payments over $2,500; arrears must be paid to reapply. Those abroad at revocation can obtain emergency travel documents from a U.S. embassy or consulate. Since 1998 the program has recovered about $657 million in arrears, including $156 million in lump-sum payments in the last five years.

Polynomial autoencoder combines a PCA encoder with a closed-form quadratic decoder (polynomial lift + Ridge OLS) to capture nonlinear variance in transformer embeddings. After projecting to d dimensions with PCA, the vector is lifted to all monomials up to degree 2, and a linear regression recovers the original embedding. No SGD; training is a single solve. On FiQA/BEIR, poly-AE consistently beats PCA at the same per-vector budget, especially at d=128 (about 8× compression) with modest gains; at d=256 gains vary by model. Practical caveats include corpus dependence and solver cost; code available.

Blaise is a modern self-hosting Object Pascal compiler built to shed legacy baggage. It uses one language mode, one UTF-8 string type (reference counted), automatic reference counting for strings/classes/interfaces, no {$mode}, no old object types, and reified generics. It targets native code via QBE (LLVM backend in development). Build with PasBuild; modules: compiler, rtl, tools, vendor/qbe. Self-hosting bootstrap complete; 1200+ tests. LLVM backend and Windows/macOS ARM64 in progress; LSP/VS Code extension planned. Community not yet accepting contributions. Apache-2.0 with runtime library exception.

Mojo is a compiled, statically-typed language that blends Python-like syntax with Rust-like memory safety and Zig-style compile-time metaprogramming, designed for high-performance AI workloads running on CPUs and GPUs without vendor lock-in. It emphasizes easy GPU programming in the same language as CPU code, with Python interoperability for importing and packaging, and seamless offloading of performance-critical parts. The site outlines getting started (stable and nightly builds), tutorials (Game of Life, GPU puzzles, Intro to Mojo), and a roadmap from core parser to dynamic OOP, with open-source plans and a community forum. Markdown versions available via .md.

The post argues SSE with Last-Event-ID can support resumable, cancellable, and multi-device token streams, but it’s not easy. Resuming requires per-token storage and cleanup; stateless replicas complicate resuming from an ID. Cancellations need a shared cancel marker so another replica can abort. Multi-device sharing is possible via stored token history, but syncing new prompts across devices without polling is hard. In short, SSE is workable but inefficient for streaming tokens; a pub/sub transport (e.g., Ably) offers persistent streams, rewind/history, and automatic cancellation routing.

Singapore has introduced caning as a last-resort punishment for male students aged 9 and above who bully others, including cyberbullying. Up to three strokes may be administered in schools, only after principal approval and by authorised teachers, considering the student’s maturity and the gravity of misconduct. It applies to upper primary levels (age 9-12) and above; female students will face detention, suspensions, or conduct-grade adjustments instead. Counseling and wellbeing monitoring follow caning. The move follows a year-long review triggered by bullying incidents. WHO warns corporal punishment harms children; global prevalence remains high.

Los Alamos has a storied neutrino program. From the Homestake solar-neutrino deficit to the discovery of neutrino oscillations, these elusive particles forced revisions of the Standard Model. The SAGE collaboration established flavor transformation and set an electron-neutrino mass limit below 1 eV, countering Soviet claims of ~26 eV. LSND hinted at sterile neutrinos, a clue debated by MiniBooNE and MicroBooNE. SNO’s results confirmed oscillations with a meV-scale mass. Today Los Alamos helps run LEGEND, searching for Majorana neutrinos via neutrinoless beta decay, while exploring dark matter and matter–antimatter asymmetry.

Collodi's 1881 Pinocchio ends with a puppet hanged, then readers beg for more; he continues with a dark, satirical saga: a dead cricket, a fairy who begins as a corpse, a donkey-skin drum, and Pinocchio nearly drowning in a fish. The violence and satire critique moralising children’s books and truancy panic in schooling. Its lasting legacy is linguistic: writing in simple Florentine Tuscan helped standardize Italian as schooling spread, turning Tuscan into everyday Italian. Today the original remains approachable; Storica offers unsanitised Pinocchio for language learners.

etke.cc introduces Komai, a desktop-first native Matrix chat client built atop matrix-rust-sdk, evolving from the nheko stack after replacing mtxclient/libolm. It emphasizes performance, readability, and openness, with features like browser-style room tabs, curated sign-up servers, advanced room search, 10+ WCAG AA themes, voice transcription, automation hooks, and multi-account profiles. Komai is Linux x86_64 only for now (AppImage/Flatpak/Snap, Arch AUR) and GPL-3.0-or-later. AI-assisted development is used; feedback is welcome. Hosting services mentioned.

Argues that the xz-utils backdoor CVE-2024-3094 was enabled by GNU IFUNC, not solely by malicious code. It links the attack to OpenSSH/SystemD decisions and shows GNU IFUNC’s runtime resolver can execute code before main, undermining RELRO. The piece notes IFUNC incurs overhead and is fragile, and that simpler techniques (function pointers, per-feature binaries) suffice. It calls for disabling IFUNC by default and requiring explicit enablement, especially outside libc.

Adam Wespiser uses Julia and JuMP to solve a mixed-integer linear program that plans Bebop the greyhound’s weekly walks for maximum activity variety and run opportunities while minimizing total distance. The model picks one activity per walk from 9 options (with distances and off-leash areas), enforcing daily structure, novelty (no repeated activities on consecutive days), and weekly variety via used_activity. Results show a near-home schedule dominated by Lincoln Park, with 9 unique activities and 8 run/play walks across a week. There are 460,800 optimal schedules among ~2.3e13 possibilities.

Hackers tied to ShinyHunters claim a second Instructure breach, defacing several Canvas login pages after a prior data breach that exposed students’ names, personal emails, and teacher–student messages. The defacement carried a message threatening to publish stolen data on May 12 if a settlement isn’t negotiated. It’s unclear how the breach occurred; ShinyHunters calls this a separate intrusion. The group previously claimed access to data from nearly 9,000 schools and 231 million people, continuing the hack–publicize–extort pattern.

JAMA, Bruch et al., analyzes nonprofit hospitals’ use of management consultants (2010–2022). Using IRS Form 990 data and machine learning, they compared 306 hospitals that began such contracts with matched controls. Findings: over 20% hired consultants; total spending reached at least $7.8 billion (avg $15.7M per hospital); including HR/IT consultants raises total to over $25B. Across net patient revenue, operating margin, liquidity, and several patient outcomes, there were no statistically meaningful improvements linked to consultant use, except a small increase in stroke readmissions. Authors call for more transparency and research.
