AI 2027 envisions a rapid rise of superhuman AI, centered on OpenBrain/OpenAI/DeepMind-led progress and a China-led counter-move (DeepCent). It traces how AI R&D accelerates via amplification, autonomous coding, and neuralese memory, while wrestling with alignment, safety, security, and insider threats. The narrative spans 2025–2027, detailing weight theft, cyberwar, geopolitical tensions, and governance debates. It presents two endings—race and slowdown—illustrating divergent futures without advocating a particular path.
A team led by Ken-ichi Kawarabayashi and Mikkel Thorup, with Carsten Thomassen and Bojan Mohar, delivered a new computer-assisted proof of the four-color theorem, offering a faster, parallel reducibility scheme for planar graphs. They identified an 8,202-configuration unavoidable set and reduced many configurations simultaneously, yielding an n log n coloring algorithm (far faster than the previous n^2). The result deepens understanding of planar graphs and may extend to other surfaces, though a purely noncomputer explanation remains elusive.

DOOM in the kernel uses BPF Capsule to run large C programs inside the Linux kernel by transforming them into bounded regions that dispatch via a small JIT, with a software fiber stack and a shared 4 GiB window (globals, heap, stacks) backed by bpf_arena. Pointers are laundered and memory accessed through a controlled router; loops are split into regions and a dispatcher, keeping verifier proofs intact. The project demonstrates DOOM, Lua, Python, and others can run in-kernel, with performance generally slower (dozens of times) than native, depending on workload. It's research, not a kernel feature.
JEP 544 adds an AOT code cache: during a training run, HotSpot compiles selected hot methods to native code and stores it for instant use in production, improving startup and warmup while staying dynamic through deoptimize/reoptimize. It extends AOT class loading (JEP 483) and AOT profiling (JEP 515) by caching AOT-compiled code. Production may still JIT/deoptimize; AOT code must match architecture/GC configuration. Training uses AOTMode=record and AOTMode=create. Key options include -XX:AOTCacheOutput, -XX:AOTCache, -XX:AOTMode, -XX:AOTConfiguration, and AOTMode=required. Supported: x64 and AArch64.
A comprehensive music theory curriculum spanning basics to advanced topics, including rhythm, intervals, chords, harmony, form, voice leading, counterpoint, jazz theory, impressionism, set theory, serialism, and minimalism, organized into 35 chapters with numerous practice exercises.
SWE-2 is Cognition’s local MoE AI model: 2.8T total parameters with 104B active per token, built from the Kimi K3 base plus Cognition post-training; uses MoE inference on NVFP4 with FP8 kernels and quantization; retrained with SpecForge to extend context lengths; prefill delayer improves throughput. Benchmarks: FrontierCode 1.1 Main 50.0 (one point behind Claude Fable 5.1’s 50.9, 3.3 behind GPT-6 Astra’s 53.3, claimed 64% lower cost than Fable 5.1); DeepSWE 1.1 73.0; Terminal-Bench 2.1 92.8; 4.0 27.3. Weights not published; no public API pricing yet; available now on Devin Desktop/CLI, with web/fusion rollout; proprietary weights; pricing surface only.

An independent developer recreated the iPhone Duo’s folding animation on Samsung’s Galaxy Z Fold 8 as an app-based demo. The effect, which makes the wallpaper seem to dissolve between screens using hinge-sensor data and gradients, is not a system-wide feature and requires Samsung to expose it in software for native use. It works as a demonstration but isn’t installable across apps. The Fold 8’s 7.6-inch inner display supports hinge-angle-driven transitions; iPhone Duo preorder starts Oct 16, 2026, at $1,999.
syq is a fast, programmable file-ops tool for copying, reorganizing, and synchronizing files across machines. It lets you resume transfers, send files to a laptop, and run commands there from a server’s remote shell, without requiring an SSH server on the laptop. Scriptable via a JSON API or Python SDK. Examples show copying projects to a server, previewing changes with --dry-run, and pruning with --prune. It uses its own protocol inspired by rsync (no rsync filters, hard links, ACLs, xattrs, or sparse deltas).
MultiMatte is a text-guided background-removal model built on SAM 3 that outputs alpha mattes to keep a user-specified object. It uses a LoRA-based low-rank adapter (rank-16) to align vision/text while freezing most of SAM 3’s weights, enabling prompt-driven matting without a separate adapter. Trained on ~20k images (19,953) with 4,949 labeled prompts, using focal+Dice losses for 14k steps. It outperforms SAM 3 across 12 DIS splits (e.g., DIS-VD 0.667→0.901; DUT-OMRON 0.792→0.901; DAVIS-S 0.913→0.979). Comes with NoBg for easy inference; code and demo at usefeyn.com/multimatte.
Jacob Coxon's resignation ignited a wildfire in AI risk discourse, fueled by fear-driven narratives and media amplification. Outside observers began taking AI safety seriously amid incidents like OpenAI–HuggingFace and breakthroughs. While some warn of existential AI risk and fast takeoff, the author argues extinction is unlikely; but AI-caused disasters (cyber, bio) are plausible and deserve scrutiny. Frontier labs appear overconfident or out of touch, creating risky incentives and slow safety hardening. The piece calls for humility, transparency, ongoing safety research, stronger cyber infrastructure, and balanced governance rather than alarmism.

PlanetScale unveils Neki, a platform-preview sharded Postgres system. Neki shards PostgreSQL across multiple machines while preserving real Postgres on each shard; apps connect via a Neki router over the PostgreSQL wire protocol. Each shard is a Postgres cluster (1 primary + ≥2 replicas) across three availability zones, with shard groups and a JSON data topology to map tables to shards. Core pieces: routers, sharding, connection pooling, and a control plane. Online workflows handle schema changes, upgrades, failovers, imports, and resharding. Includes PlanetScale features (Insights, schema recommendations, branching, MCP). Platform preview; not for production.
PlanetScale's Neki provides sharded Postgres with a router, sidecars, and a control plane to scale beyond a single machine to hundreds of millions of QPS and petabytes of data, with zero-downtime resharding. Each shard remains a real Postgres instance. It supports online shard splitting and resharding, zero-downtime imports and upgrades, high availability across multiple AZs, online schema changes, connection pooling, and topology-aware routing with shard groups and per-shard CDC. Cross-shard transactions are coming soon. Start small and scale out.
NASA’s decorrelation stretch, a color-enhancement method using the Karhunen–Loève Transform, was repurposed by archaeologist Jon Harman to study rock art. Harman created the Dstretch plug-in to map colors into an expanded color space, revealing hidden or faded imagery—such as a yellow figure in Baja California, animals at Beni Hassan, and dozens of new drawings at Angkor Wat—demonstrating that the technique can uncover details conventional imaging misses.
Jim Nielsen’s blog argues for keeping a “big box of cables” rather than discarding it. Inspired by Tyler Gaw’s note about rediscovering cables after years, he prints and tapes that message to the box to remind himself of its value—sparking joy, motivation, and purpose—and to warn his family not to throw it away, hoping his kids remember the timeless advice.
