The EU is about to sell our most sensitive data to the US for visa-free travel

EDRi warns the EU is close to finalising a Framework Agreement with the US under an Enhanced Border Security Partnership, enabling automated sharing of biometric data and risk-based profiling of travellers. A leaked draft suggests the EU has caved to US demands for extensive information access, risking broad data transfers, discrimination, and rights violations, potentially incompatible with EU law and the Charter. Talks are secret; EDRi calls EU leaders to resist, uphold safeguards, and not sell citizens’ data to a country with poor human rights records.

Stop Using OpenCode

OpenCode teardown: despite popularity, it's a dangerous, poorly engineered coding agent. The author deems its security posture atrocious and details systemic flaws: clumsy prompt caching, pruning and compaction that wreck context; permissions that let clankers escape boundaries; file and redirection handling is broken; remote-by-default operation (remote model connected by default) and un-sandboxed network access; insecure upgrade flow via curlbash; potential RCEs via web fetch and exposed endpoints; subagents misbehave; poor UX; conclusion: stop using OpenCode and consider local LLMs cautiously.

Features photos, an ongoing online collection, a DIY moisture-wipe recipe, and donation details. The exhibit is housed at Michigan State University’s Abrams Planetarium in East Lansing, with public hours 9:30–4:30 Tue–Fri. Updates and contact info are provided on the site; donations are welcomed.

The Trump administration's Threat to Scientific Research

Airbus Takes Flight from AWS

Airbus plans to move about 900 applications from AWS to Scaleway, prioritizing 70 initially, to keep critical data under European control and advance digital sovereignty. The migration targets ERP, CRM, and manufacturing systems, but supply-chain data—from 18,000 suppliers—will remain difficult to localize due to widespread Microsoft/Google usage. Airbus appears wary of AI for critical systems, favoring on‑prem or EU-hosted solutions. The move could spur a broader European sovereign-software market via tenders, potentially challenging US cloud dominance.

What does the Riemann zeta function have to do with the distribution of primes?

The article traces how the distribution of primes ties to the Riemann zeta function. Euler's zeta function equals the product over primes, linking sums over all n to primes. The sum of prime reciprocals diverges, showing primes are not too sparse; the partial sums grow like log log n. Gauss conjectured pi(N) ~ Li(N), later refined by Riemann: pi(x) ~ Li(x) − sum Li(x^ρ) over zeta’s nontrivial zeros ρ. Since Li(x) ~ x/log x and |Li(x^ρ)| ~ x^{β}/(|ρ| log x) with 0<β<1 and symmetry ρ↔1−ρ, the error terms are smaller. RH posits β=1/2 for all ρ, yielding the strongest form of the approximation.

When can a power company take your land for data center infrastructure?

As data centers grow, power companies must build transmission lines that often cross private land. If landowners refuse, eminent domain can be used for “public use” with just compensation. The federal standard from Kelo is permissive, but many states have tightened rules; some, like Michigan, Ohio, and Oklahoma, prohibit taking for purely private economic development. Utilities generally prevail, but challenges arise when lines mainly benefit out-of-state or don’t clearly help in-state customers. Overall, seizures may be allowed to improve grid reliability for in-state customers, with state-specific, case-by-case outcomes.

EU Exempts Apple Watch and AirPods from Battery Removal Requirements

EU regulators granted exemptions to the Batteries Regulation, allowing Apple Watch and AirPods to skip user-removable batteries. The Commission cited risks of water ingress from opening sealed devices, or the danger/feasibility issues of replacement given current manufacturing methods. The iPhone remains exempt. The exemptions must still undergo scrutiny by the European Parliament and the Council before implementation.

Eliminating Go bounds checks with unsafe

Bound checks elimination (BCE) is a robust Go optimization that reduces instructions and branches, helping caches and register pressure. When the compiler can’t prove a bound check is unnecessary, unsafe techniques can remove it. The post shows an unsafe pattern to replace a safe 4-byte little-endian load with pointer arithmetic that yields a leaf function and eliminates all bound checks: unsafe.SliceData, unsafe.Add, and unsafe.Pointer. Benchmarks: the unsafe version runs >2× faster than the std loader; in a real Brotli matchfinder it yields ~10% throughput gains. Caveat: unsafe is risky; you must prove bounds aren’t needed.

How proprietary formats have become Microsoft’s main tool for lock-in

Proprietary Office formats, especially OOXML, create lasting lock‑in by tying documents to the software that created them. Even with ISO standardization, the spec preserves legacy Microsoft behaviours that only Microsoft software fully implements, making interoperability fragile. Dependency ranges from individuals to governments, risking future accessibility as formats evolve. True digital sovereignty requires open standards (ODF), open fonts, open templates, and long‑term archival formats (PDF/A) enforced by governance for official documents.

Self-Powered Trailers Promise Leaner Freight Runs

Europe and North America are moving beyond whether powered trailers work to which architecture is most economical. Nivalis Energy Europe’s retrofit uses a 50 kW electric axle, a 60 kWh battery, rooftop solar up to 3.7 kW, and a 32 A grid connection, with savings from regenerative braking, solar, and dwell-time charging. Trailer Dynamics reports up to ~40% fuel savings with 300–551 kWh batteries, while ZF TrailTrax promises up to 16% (plus regen) or 40% with plug-in charging. Payback estimates range 3–6 years; no standard savings metric exists. Regulators could allow extra payload later.

Xiaomi-Robotics-1

Xiaomi-Robotics-1 is a two-stage robot foundation model trained on 100k hours of embodiment-free data, with post-training on real-robot data. Pre-training uses auto-labeled video-language descriptions of scene state transitions to learn action generation; post-training aligns with real robots and natural-language instructions. Scaling data and model size yields steady gains in real-robot success, with no saturation. In unseen environments, larger pre-trained models perform better after post-training. Applications include efficient adaptation to new tasks (e.g., phone packing, laundry loading) from ~10–40 hours per task, and state-of-the-art simulation benchmarks. Conclusion: large-scale UMI pre-training breaks the data bottleneck and transfers to physical robots.

LoRA Speedrun – a public wall-clock leaderboard for fine-tuning techniques

Saivineeth147/lora-speedrun is a public benchmark for fast, frozen-task LoRA fine-tuning on Qwen2.5-1.5B with GSM8K, using a single NVIDIA L40S in Modal sandbox. The aim is to beat wall-clock time while reaching ≥57% exact-match on GSM8K (0-shot, greedy). It uses modded-nanogpt and a three-run verification to ensure fair comparisons. The repo offers baseline, a leaderboard, and PR-based submission/verification with security checks. Current record: 6m05s at 61.1% (2 epochs) by the author.

Korg PS-3300 is back

Korg reissues the iconic PS-3300, the ultra-rare polyphonic analogue synth originally made 1977–81 (under 50 units). Recreated with Fumio Mieda and Korg’s revival team, it uses three PSU-3301 sound generators in a semi-modular, hand-built package with modern reliability. It preserves the original’s exploratory interface, patch points, and polyphonic/tuning features, including temperament knobs and a dedicated tuning mode. Specs: 49-voice polyphony, 49-key keyboard, 7 octaves, 256 programs, built-in MIDI/USB, and a custom hard case. Limited edition; purchase via a structured, first-come process in the UK.

The Chickens and the Bulls (2012)

Slate recounts 'The Chickens and the Bulls,' a 1960s extortion ring that preyed on closeted gay men by posing as police detectives. Using 'chickens' (male prostitutes) and 'bulls' (fake cops), the operation spanned cities, victimizing thousands and taking at least $2 million from figures including a congressman, generals, an admiral, and a Princeton professor. The NYPD’s Rackets Squad and the FBI built case; leaders included John Pyne, Sherman Kaminsky, and John Fellabaum, with Hilton security chief Ed Murphy providing help. The break-up in 1966 exposed police pretense, spurred reforms, and foreshadowed Stonewall, with Murphy later an advocate.
