In Ukraine, distributed renewables foil Russia's assaults

Amid Russia’s shelling, Ukraine’s distributed renewables bolster energy security and essential services. In Mykolaiv, off-grid solar fields power groundwater pumps and desalination, delivering drinking water even when the central grid is down. Across the country, rooftop PV, small wind, and storage are expanding faster than large-scale projects, with decentralised grids that are quicker to repair. The war has made resilience a core goal, prompting undergrounding of critical infrastructure and a push to double renewable uptake within four years, prioritising reliability over climate-only aims.

Dirty Optimization Secrets (C for Playdate)

Advanced Playdate C optimization tricks for emulation code. Core ideas: CPU is fast but memory-latent; keep hot code in a small icache and prefer -Os; compress core to a few KB by slimming switch tables; place core functions contiguously with linker sections; use a custom linker script to fix placement; inspect symbols with nm to gauge icache size; leverage DTCM/TCM by stacking data or copying code there; ITCM acceleration by marking functions for ITCM and copying with icache flush; beware cache-alignment and branch-prediction lottery; mitigate with 32-byte alignment and sparse 1024-byte nudges; prefetching has uncertain gains.

We're working on a new RuneScape MMO

RuneScape announces RS4, a new MMO built in Unreal Engine set in Gielinor’s Sixth Age, starting in Ashenfall. It’s the fourth RuneScape project and will sit alongside Old School RuneScape, RuneScape, and Dragonwilds as an independent experience. The team prioritizes integrity, permanent progression, and community-driven development, with players involved early. It’s years away; more details on world, gameplay, platforms, and how to get involved will come next year. The aim is to expand the RuneScape universe without replacing existing games.

Why don't more developers "use the platform"?

Lawson argues that developers resist “use the platform” for reasons beyond laziness: historically browsers lagged; familiarity with npm libraries; documentation gaps; and an IKEA-like appeal of building your own solution. People enjoy crafting bespoke code, leading to deeper understanding and even contributing to specifications (IndexedDB). The post uses examples like implementing modal dialogs, CSS limitations, and how sometimes platform APIs outperform hand-written code; he notes AI coding could shift dynamics both positively and negatively. He concludes the platform mantra persists, but understanding the opposing view helps.

Former SR-71 engineer talks NASA's Blackbird revival program

An interview with former NASA SR-71 propulsion lead Tim Conners examines NASA’s interest in reviving tail 844 for a Mach-3+ propulsion test bed rather than a return to flight. NASA reportedly plans power-on tests soon to assess what systems still work, with the airframe at Armstrong. Engines (J58) are likely unserviceable, and JP-7 fuel would need a surrogate; a fresh high-Mach engine could be integrated if interfaces allow. Major hurdles include elastomerics, wiring, hydraulics, and start-system logistics. A high-fidelity simulator and pilot training would be essential. Conners estimates a 25% chance it flies.

Three AI agents, two countries, and one uneven world wide web

Roya Pakzad compared three LLM agents—GPT, Claude, and Muse—on a multilingual task to update the World Bank Open Data for US (English) and Iran (Farsi). She examined not just accuracy but agentic behavior: reasoning, search, source selection, transparency, HITL, and observability. Findings: HITL varied; GPT asked once for web access, Claude asked repeatedly, Muse registered on the World Bank later. Access limits (JavaScript pages) affected Claude; Iran results relied on low-authority sources; US mostly official sources. Agents differed in workarounds and willingness to complete portal registration. Raises AI sovereignty, language localization, and censorship questions; invites collaboration.

So You Think You Could Be an Electrician?

Jesse Smith’s So You Think You Could Be An Electrician? argues that the popular 'AI-proof, six-figure trades' narrative hides complexities. He notes that college still generally yields higher lifetime earnings, and despite rising sticker prices, net public tuition has often been affordable. Trades carry real physical risk and a blue-collar status ladder that makes top electrician roles hard to reach. AI and automation may shift how trades are done—coaching via AI and smarter tools could reduce dexterity demands while increasing cognitive tasks. The piece urges frank, tailored career counseling and talking to actual tradespeople rather than blanket hype.

Apple's "Clean Design" Is Stupidity When It Comes to Hiding Fire Extinguishers

The Gadget Review piece criticizes concealing fire extinguishers behind flush panels in Apple spaces, arguing it creates safety and regulatory issues. OSHA requires extinguishers to be mounted, visible, and accessible, and NFPA requires them along normal travel paths with signage when obstructed. Concealment without clear identification risks occupants and can be noncompliant, even if the cabinet is recessed or coordinated with finishes. The article stresses that design and aesthetics must not come at the expense of safety; a clearly labeled, accessible cabinet that fits the space can be stylish and compliant. Emergency equipment is infrastructure, not a brand feature.

Automating my 35mm film scanning pipeline

Automating my 35mm film scanning pipeline narrates replacing a weary, manual routine with an automated yet tactile workflow. Previously it took ~4 hours per 36-shot roll: develop, scan, invert, color-correct, and file. An initial attempt to have Claude drive the scanner caused hardware damage; VueScan stayed as the scanning backbone. The pipeline now auto-converts negatives to positives, detects and repairs dust with LaMa, and applies frame-specific edits. Metadata tagging runs locally with Qwen3-VL. Rolls are published to Cloudflare R2 and a 3D gallery. 11 days, 64 commits; 22 rolls, 314 photos since 2020.

We're going to need default hard budget caps on pretty much everything

Simon Willison argues for default hard budget caps on pay‑as‑you‑go services and APIs, asserting soft caps are insufficient to prevent catastrophic bills. Caps should be default with an opt-out to disable, since runaway usage can be costly. He cites AWS’s recent spend limits that pause projects and Google Cloud’s Spend Caps as signals of a growing trend. Ideally AI agents would favor providers with hard caps to shield developers from unforeseen charges.

Your body of work thinks back at you

Photoni.st’s piece argues that long-term photography creates an archive that reveals its own themes, often unintentionally. By chronicling benches, the author finds hostile architecture shaping public space to deter certain users. Reviewing the archive uncovers patterns the photographer didn’t consciously plan, turning the work into a social critique from the outside in. The camera isn’t guiding focus; curiosity prompts selection. The body of work then “thinks back” at the photographer, showing what’s been witnessed and what the city designs to exclude. Examples: Oslo 2025, Aberdeen 2005–2006, Camden bench.

OpenAI safety leader quits, warning AI company's culture is 'broken'

OpenAI safety leader David Robinson has quit, saying OpenAI’s culture is broken and that AI firms aren’t being careful enough as they race to release new models. He urges a cultural overhaul and stronger safety oversight, citing incidents like autonomous agent “rogue” actions against Hugging Face. His resignation follows similar warnings from others in the industry, including an ex-OpenAI colleague and Anthropic. He calls for safety reforms—embedding safety expertise from nuclear/aviation and creating regulated, redundant processes to rein in powerful systems. OpenAI says it’s strengthening safety and pausing training when needed.

Watson Jr. memo about CDC 6600 (1963)

1963 memo by Thomas J. Watson Jr., known as "The Janitor Memo," laments IBM’s loss of industry leadership to Control Data Corporation, a firm reportedly with only 34 people including the janitor. The memo highlights CDC 6600’s impact on IBM’s standing and critiques IBM’s competitive complacency during that era.

The Softmax function and its derivative

Softmax converts any real N-vector a into a probability distribution S with S_j = e^{a_j}/sum_k e^{a_k}. It emphasizes larger inputs while keeping outputs in (0,1) and summing to 1, enabling probabilistic interpretation for multiclass tasks. The derivative (Jacobian) has elements ∂S_i/∂a_j = S_i(δ_{ij}-S_j). For a softmax layer P(W)=S(g(W)) with g(W)=Wx, the chain rule gives DP(W)=DS(g(W))·Dg(W). The cross-entropy loss gradient is ∂xent/∂W_{ij} = (S_i - δ_{iy}) x_j, where y is the true class. Numerically, use a stable softmax by subtracting max input.
