A Zhejiang University study (NeuroImage) scanned 56 young adults watching six-minute video blocks. The dorsal anterior cingulate cortex (dACC) and dorsolateral prefrontal cortex (dlPFC) deactivated significantly only for clips participants finished liking; disliked clips showed less suppression. Resting-state dACC glutamate predicted deactivation magnitude—higher glutamate linked to less suppression; GABA did not predict dACC/dlPFC activity. dACC–dlPFC connectivity increased during liked videos. Authors caution this reflects a shift to low-effort processing during absorbed viewing, not impaired cognitive control, and note several limitations.

Project Cybersyn in Allende’s Chile trialed cybernetic economic management via four components: Cybernet (a telex link from factories to CORFO and a single mainframe), Cyberstride (an anomaly-detection program), CHECO (a macroeconomic simulation), and a central operations room. In practice, the telex network was useful for records and some coordination during the 1972 strike; Cyberstride lagged and offered few actionable warnings; CHECO’s models were not consulted; the room displayed handcrafted charts. The system was centralized, did not decentralize planning or involve workers, and was not a viable replacement for markets. Still, it was a bold, instructive effort for modern dashboards.

Chris Said explores how the USSR tried to optimize a centrally planned economy, detailing how annual plans were built from hand-made balance sheets with severe simplifications (dimensionality reduction, aggregation, truncated cascades), causing shortages and idle factories. In late 1960s, 'optimal planners' applied linear programming to align factory outputs and inputs, with limited gains due to political constraints, propagation gaps, and misaligned objectives. The piece discusses broader feasibility of full economy optimization, citing computational complexity, data quality, nonlinearity, incentives, and political resistance. It ends noting future tech could address some issues, but democracy and incentives remain unresolved; recommends Red Plenty access.

Defense-tech valuations have far outpaced the market, creating a bubble. The genuine addressable market for new entrants is much smaller than headline defense budgets—perhaps a single-digit to low-tens-of-billions by decade's end, with most funds already spoken for in programs of record and legacy primes. As capital cools, a consolidation wave is expected: mutual-convenience mergers among peers; recaps to reset valuations; acquisitions by primes and mega-startups; and rollups by private equity. Survival hinges on real revenue, owning customer relationships, proven field performance, scalable unit economics, and sufficient runway. Many startups will be recapitalized or merged rather than fail.

Andrew M. recounts the 2026 StratoSpore/Uplink balloon run in Montana. Building on last year, he added GPS redundancy and improved image transmission via SSDV over LoRa and a 320x240 camera. He tested a 3D-printed foam‑PLA enclosure versus traditional foam; the foam was lighter but insulation results were inconclusive; sensors stayed ~7°C warmer inside. The payload used an ESP32-S3 XIAO, MCP3204 ADC, and a buck-boost regulator; firmware moved to Arduino. The balloon rose to 28.42 km, traveled ~140 km, but the payload was not found after ~5 hours. U4B tracker failed. Data and code are on GitHub.

James Somers argues that biology is more than memorized names; real understanding comes from asking big questions (embryo differentiation, gene regulation) and viewing biology as recursively self-modifying programs. He traces his shift from rote pathways to appreciating structure, function, and diffusion, citing Avery’s transforming principle, Hofstadter, Goodsell, and Judson. He extols practical methods (RNA-seq, Western blots, flow cytometry) and the need for vivid visuals to convey complexity, plus collaborative tools (Victor’s Dynamicland, BioRender, CellPAINT) to create shared, navigable maps of biology.

Linux 7.2 released, one of the busiest cycles; key advances include cache-aware scheduling, MGLRU improvements, sub-schedulers for sched_ext, and automatic multi-size transparent hugepages. Igalia contributed notably to the DRM scheduler fair policy (default remains FIFO due to a last-minute regression), enhanced sched_ext observability, and runtime power management for Raspberry Pi GPUs, plus fixes for Pi 3/4/5 GPU stability and broader bug fixes. The release also advances HDMI 2.1 FRL support in amdgpu and ongoing futex and kernel reliability improvements.

Go 1.27 adds generic methods with method-level type parameters, enabling methods to be generic without adding type parameters to the receiver. Previously, only functions and structs could be generic; methods couldn’t, forcing per-method type parameters to live on the receiver and creating awkward APIs. Now you can write Map[U any]() on Node[T]. The delay came from monomorphization and the runtime nature of interfaces: generics are resolved at compile time, while interfaces are dynamic, which would blow up binaries if generic methods lived in interfaces. Therefore, Go allows generic methods on concrete types, not on interfaces.

Scrambling text with 'anti-AI' fonts is ineffective and harmful. Such fonts are inaccessible because screen readers and accessibility tools rely on readable text, and implementing them requires metadata that would enable centralized verification and raise privacy and security concerns. The post argues these fonts—like Decoy, Shield, and Ghost—do not solve the problem and merely push it into a cat‑and‑mouse arms race, as AI models learn to bypass obfuscations. Widespread obfuscation could enable censorship and paywalls, undermining the Web's plaintext, open-access ethos. No silver bullet exists; information will become broadly accessible anyway.

Semantic invariants are the truths about memory and data (extent, lifetime, ownership, identity, arithmetic) that must hold for a program to operate safely. C’s types reveal little of these relations, so programmers carry them as implicit assumptions. Violations propagate through a chain from size calculations to allocations, pointers, and memory operations, producing vulnerabilities such as integer overflow, buffer and out-of-bounds access, use-after-free, and double free. Testing cannot guarantee invariants; the solution is memory-safe language design that encodes and enforces these invariants (spatial and temporal safety).

An IT job phishing scam via LinkedIn lures Software Engineers with a quick remote coding test. The test loads remote code from jsonbin.io that executes via a remote-code loader, then pulls obfuscated malware that connects to a C2 at 147.189.174.138:7321. It installs a RAT with full shell, file grabber, clipboard monitor, key/credential theft across browsers, wallets, and crypto keys, enumerating user directories and drives. It fingerprints VM vs bare metal to evade sandboxing. Precautions: AI scans, Docker, or especially Vagrant isolation; after attack revoke keys, rotate secrets, reinstall OS; the fake profile was deleted.
