An IBM ThinkPad 750C (circa 1994) with I9990303 blocks boot and BIOS access, though maintenance disks can boot. IBM docs link I9990303 to a faulty ROM/flash, sometimes a flash ROM checksum error in newer models. The BIOS updater fails due to power-management/battery checks. The author hacked UPDTFLSH.EXE to bypass checks, flashed the BIOS, and the error disappeared, with BIOS configuration and PS/2 utilities restored. Conclusion: I9990303 almost always signals corrupted flash memory; bypassing safety checks can fix it, though it’s risky.

vllm-torchtpu is the PyTorch-native TPU backend for vLLM, an out-of-tree plugin that runs vLLM’s PyTorch models on Google Cloud TPUs via TorchTPU and custom JAX/Pallas kernels for attention, MoE, and quantized matmul. It preserves the standard vLLM experience with TPU-optimized kernels (Ragged Paged Attention, dense/sparse MLA, fused MoE, FP8/INT8/MXFP4) and scales across TPU slices. JAX backend is separate; torchtpu is recommended for PyTorch models. Hardware: TPU v7x (recommended); v6e/v5e experimental. Get started: Python 3.12, pip or Docker. Serve with vllm serve; cache artifacts with VLLM_XLA_CACHE_PATH. Supports many models (Llama, Qwen, GLM, Gemma) and Kubernetes multi-host deployment. Contributions welcome.

The Karakoram Anomaly is the observed mass gains of some glaciers in the Karakoram range ( Pakistan, India, China, etc.) since the 1990s, unusual compared with glacier thinning elsewhere. Early ideas blamed debris on ice, but debris likely isn’t the sole cause. A 2020 review attributes the effect to meteorological factors, especially increased winter snowfall from westerly winds; a 2022 study notes about a 10% rise in Karakoram winter precipitation since 2000. Debates persist on the exact area, duration, and whether the behavior truly constitutes an anomaly in a warming world.

Corbin Davenport argues that PowerShell 7, the cross‑platform successor to Windows PowerShell, is a powerful automation tool. He contrasts it with Bash, noting Bash’s boilerplate and cross‑platform quirks, while PowerShell offers built‑in cmdlets, objects, and JSON handling. He shows this with examples: a Bash mp3 downloader vs a PowerShell version using Param and Get‑Help; registry access via virtual drives; Invoke‑WebRequest for downloads; and scripts like Just the Browser and Tumblr‑to‑Eleventy that preserve metadata and produce JSON. He’s impressed and plans to keep learning.

WorldTUI trains a 360M-parameter model to act as a terminal by predicting screen deltas per keystroke, not text streams. Starting from a session snapshot, the model receives raw keycodes and outputs which screen rows to rewrite and the new cursor position. It runs in a browser (208 MB, WebGPU) without a real shell. Trained on 336k synthetic terminal sessions in Docker, memory and persistence are improved via a COPY row operation and self-correction (DAgger-style). It supports bash, vim, tmux, Python, and Snake, though not a reliable filesystem yet. Gains: parallel-row decoding, speculative decoding, memory accuracy 9/13. Future work.

Late medieval clock metaphors linked cosmic order, theology, and court politics by portraying motion as dependent on ongoing maintenance rather than self-sufficiency. Nicole Oresme likened celestial motion to a clock, yet allowed angels to move the heavens, showing tension between autonomous mechanism and divine intervention. Across authors such as Mézières, Froissart, Petrarch, and Chaucer, clocks symbolized temperance, Providence, and governance, with horologists as crucial mediators who repair and regulate. The metaphor thrived in courtly culture and reflected a shift toward Augustine-inspired views of law, grace, and human agency, reframing technology as contingent and socially embedded.

Kairos’ Check 1 pits a real 30-day lived memory (Test-A) against a forged autobiography (Aria) written to match length/format. Three LLM judges scored them almost identically, +0.032 within ±0.10, implying text can mimic lived memory. Passages are quoted verbatim; the living memory tests continuity, not subjective experience. Caveats: judges didn’t see the originals; the counterfeit was matched by length/format, not style. A log records what actually differentiates lived memory.

An in-depth look at reverse engineering the Hitster Android app shows how QR cards map to regional Spotify/Apple Music tracks, not a single ID. The author decompiles the APK, finds a supposedly encrypted local database (gameset_database.json), and documents an AES-GCM decryption flow. They chase a secret key, XOR two 32-byte arrays to obtain a decryption string, and build a Rust decryptor to map card IDs to tracks. Ultimately, the data is publicly available at hitster-assets/gameset_database.json—no real secret. Credits to Mr.Corrupt.

Postgres recovery_prefetch can cause outages in synchronous replication by turning primary I/O bursts into many small random reads on replicas, dramatically increasing read IOPS and delaying WAL replay. Field reports (Feb 2021 discussion pre-merge; Mar 2025 reproduction) show standby lag or hangs when recovery_prefetch is active; disabling it (while FPWs stay on) eliminates the issue in tests. The piece explains the standby state machine and the sensitivity to streaming interruptions, and suggests disabling recovery_prefetch as a precaution and considers two standbys with quorum commit for resilience.

LLMs cannot be trusted to generate reliable confidence scores because those numbers are just token continuations, not measurements of uncertainty, and they aren’t calibrated to real outcomes. Confidence should reflect the information used and be checked against what actually happened (calibration). Using a forecaster analogy, the article shows how scores drift with wording and context. To get trustworthy confidence, implement an external rule that converts observable signals into a probability, baseline it on past results, update from new data, and audit it regularly.

Oliver Grabner builds a Pokémon Showdown 2v2 multi-agent LLM coordination environment to study how teammates coordinate and communicate. Each turn an agent reads a battle summary, selects a move, and may message its partner. Four talk modes are evaluated: free talk, one message each, no talk, and one model controlling both Pokémon. Against a max-damage bot, free talk achieves 64% win rate, beating no-talk (42%) and one-message (52%), while one-model control is 54%. Talking increases token usage (978k vs 259k). Stronger opponents narrow gaps. Future work: separate talking from seeing moves, leaderboard benchmarks, and RL to foster collaboration.

A Notre Dame–backed survey of 557 Americans finds age and religiosity shape moral self-perception and self-reflection. Young adults (under 35) are most likely to feel far from the person they ought to be (38%), while 55+ respondents largely feel close or already there (about half). Older people report more daily attempts to improve character but reflect on actions less. Religiously active people reflect more than non-religious; among the young this gap is largest. Among older non-religious respondents, moral confidence dominates over reflection, suggesting greater contentment. Overall: self-improvement appears to be a younger phenomenon.

At RustConf 2026, Tyler Mandry outlined 'Beyond the &' to align user-defined smart pointers with Rust's borrow checker by exposing the compiler's 'place' concept. The plan: create a handle type for each smart pointer and traits (BorrowPlace, WritePlace, ReadPlace, ProjectPlace) that describe how to read, write, and project from a place. This would let libraries implement pointer-like behavior as if they were built-in references, e.g., making MutexGuard-compatible accesses in shared contexts. A prototype is discussed; syntax options include BorrowPlace implemented with an @ or similar. Next steps: implement errors/diagnostics and gather community input; stabilization pending.

Airbnb updated its house rules to bar hosts from requiring guests to perform chores that require significant effort or would typically be done by a cleaner, for bookings made on or after Nov 20. Allowed tasks include putting used dishes in the sink, gathering towels, sorting trash and recycling into indoor bins, and turning off amenities when leaving; guests aren’t required to wash dishes, strip beds, or haul garbage off-site. A new "rules and requests" section highlights hosts’ requests, with an animal-proof trash disposal exception in bear country. Some hosts push back, and guests can avoid overly strict listings.

FoxIO reports QPACK amplification attacks on HTTP/3 that let a remote, unauthenticated client force a server to allocate far more memory than the compressed HEADERS on the wire. By abusing decoded-header size budgets (and missing 32-byte field overhead), a small HEADERS frame can expand to hundreds of thousands of headers, potentially exhausting memory or crashing. Seven of ten tested implementations were vulnerable; several have been fixed (quic-go, quiche, lsquic, h3, etc.), while others remain vulnerable or partially fixed. The fix is enforcing a cumulative decoded-header budget during decoding and avoiding preallocation based on compressed size.
