Unity’s use of coroutines in C# clarifies their value for timed effects; in C++ they’re hard to adopt due to co_await complexity and the need for custom schedulers. The author contrasts a Unity TimeWarp example (yielding each frame) with a boilerplate C++ state-machine, then shows a compact Unity-like runner in C++ using std::generator<std::monostate> to manage and drive effects every frame. A minimal effects_manager handles adding, advancing, and pruning coroutines; bonus: generators can yield Draw objects too. The piece argues this yields readable, extensible game logic and anticipates future C++ execution/support (C++26).

A New Mexico jury ordered Meta to pay $375 million for misleading users about child safety on Facebook, Instagram, and WhatsApp, ruling the company exposed minors to explicit material and predators and violated the state’s Unfair Practices Act. Internal docs and a whistleblower testified Meta knew of harms; jurors found thousands of violations (up to $5,000 each). Meta says it will appeal and cites safety efforts like Teen Accounts and parental alerts. The case is part of a wave of child-safety lawsuits against Meta.

Michiels explains he forked httpx to httpxyz after repeated release delays, ignored fixes, hidden issues, and debate over a disruptive 1.0. Citing maintainer burnout and governance concerns, he aims for a stable, non-breaking fork with incremental maintenance. The plan: no major rewrites, no breaking changes for now, just a faster, more reliable path. Co-maintainer Sander Wegter shares the load. Plugins may not all work, but porting is possible. He hopes for a future HTTPX2.

Alex Wellerstein discusses the 1961 Goldsboro, NC B-52 crash, where two Mk-39 bombs were jettisoned. One bomb landed in mud and its high-explosive detonated; the other nearly detonated, its final arming step blocked by a crude ready-safe switch. Sandia produced an internal safety video; a 1987 review notes that breakup dynamics could have armed the device. The post places the episode in broader debates about nuclear safety, McNamara’s fears of accidental launches, and Eric Schlosser’s Command and Control, while noting today’s weapons are safer but not risk-free.

TurboQuant, with QJL and PolarQuant, is a compression method for large language models and vector search that achieves substantial memory reductions with zero accuracy loss. It first applies PolarQuant to polar-coordinate mapping after random rotation, then uses QJL to eliminate residual errors with a 1-bit sign representation per dimension, yielding zero memory overhead. Experiments on LongBench, Needle-in-a-Haystack, ZeroSCROLLS, RULER, and L-Eval with Gemma and Mistral show at least 6x KV cache memory reduction, up to 8x attention-logit speedups on H100, and near-lossless 3-bit quantization. Presented at ICLR 2026 and AISTATS 2026. Implications for semantic search at scale.

An in-depth look at Arm Mali CSF firmware for v10 GPUs (mali_csffw.bin). The GPU’s MCU is a Cortex-M7 running up to ~990 MHz, with its own MPU and MCU mappings that work with the GPU MMU to access memory. The post explains the three-layer memory model, key regions (0x04000000 and 0x40000000), and how doorbell interrupts work. It details the firmware image format (interfaces, tracebuffers, metadata) and how to load it. It also covers debugging with a gdbserver (MRI), running MicroPython on the MCU, Rust tooling, and reverse-engineering efforts in panfwost/panloader, crediting Alyssa Rosenzweig.

UK teenagers will take part in pilots testing social media bans and digital curfews at home. About 300 youths will be split into four groups: full app bans, 60-minute daily limits, 21:00–07:00 restrictions, and a control group. The aim is to compare effects on sleep, schoolwork and family life to inform whether under-16s should be blocked from many social sites, alongside a government consultation. Separately, a Wellcome Trust-funded study will enroll 4,000 pupils aged 12–15 from Bradford to assess wellbeing impacts of reduced social media use (sleep, anxiety, social interactions, absence, bullying).

Bret Devereaux argues the US war on Iran was an ill-considered gamble that produced no strategic gains and worsened security. Iran’s large, institutional regime is unlikely to fall to decapitation, and its nuclear program remains intact. The regime-collapse objective failed, even as Israel risks blowback. The conflict risks a Hormuz chokepoint escalation, disrupting about 25% of global oil and 20% of LNG/fertilizer shipments. Costs—casualties, billions daily—outweigh any payoff. De-escalation and negotiated limits are essential to avoid mutual ruin.

The post argues that running a DNS server isn’t hard and recommends PowerDNS with a database backend. It shows how to manage DNS by inserting records, then demonstrates sample CNAME and A records. The practical approach is to host a subdomain of your domain and point its NS to your own DNS server for resilience, while keeping the main domain with your registrar. This avoids editing registrar UI for every record and eases management. Authored by Simon Safar.

VitruvianOS is a Linux-based, BeOS/Haiku‑inspired OS focused on fast, out-of-the-box usability with a tightly integrated desktop, user control (no data collection), and a community-driven model. It ships with the Nexus Kernel Bridge to run Haiku apps on Linux, and uses a real-time-patched Linux kernel while supporting non-RT kernels. Defaults are ready-to-use, with plans for features like filesystem indexing, live queries, and multiuser login. Supported filesystems include XFS and SquashFS. Questions via GitHub/Telegram; updates posted on the site.

An experimental DuckDB extension fork that adds ACORN-1 filtered HNSW search. It pushes WHERE predicates into the HNSW traversal so queries with ORDER BY distance and LIMIT return the exact number of results, avoiding post-filtering losses. It uses a selectivity-based strategy: ACORN-1 for 1–60% selectivity, post-filter for >60%, brute-force for <1% (configurable via hnsw_acorn_threshold and hnsw_bruteforce_threshold). Usage: CREATE INDEX … USING HNSW (vec); SELECT * FROM t ORDER BY array_distance(vec, …) LIMIT 10. Metrics: l2sq, cosine, ip. Supports insert/update/delete with compaction; RAM-bound; built with make; MIT.

BlackRock boss Larry Fink warned that oil at $150 a barrel could trigger a global recession if Iran remains a threat. He outlined two scenarios: prices fall below pre-war levels with settlement; or a prolonged period of “above $100, closer to $150,” with grave consequences. Energy costs are regressive, and high prices for years would push nations toward solar and other sources. He rejected an AI bubble but said AI will create many jobs, especially in skilled trades, and urged diversification to enable AI growth. There are no 2007-08 similarities.

Device Modeling Language (DML) is a domain-specific language for fast functional or transaction-level device models for virtual platforms. It provides constructs like register banks, registers, bit fields, event posting, interfaces between models, and logging. DML code is compiled by the DML Compiler (DMLC) to C with simulator-specific APIs, currently for the Intel Simics simulator (other back-ends may be added). Building/testing DMLC requires a Simics installation; in a Simics project, run make dmlc and bin/test-runner or make test-dmlc. Environment vars guide: DMLC_DIR, DMLC_JOBS, DMLC_PATHSUBST, PY_SYMLINKS, etc.

An approach to encode the POSIX socket state machine in Lean 4 to remove runtime checks. The socket has five states: fresh, bound, listening, connected, closed. The socket type carries its state as a phantom parameter; functions declare exact pre/post conditions (socket .fresh → bind → .bound, then .listening, then .connected, etc.). A final close includes a proof that the state isn’t .closed; the proof is discharged by the kernel and erased at compile time. Invalid sequences (send on fresh, accept before listen, double close) fail to type-check, yielding no runtime overhead. The generated code matches raw C.
