Spacecraft generate far more data than can be downlinked; for example, NISAR is projected to produce about 85 TB/day, likely exceeding a full day’s capacity. Data growth is driven by higher‑resolution sensors, hyperspectral data, regulatory requirements, mission complexity, longer lifetimes, and rising commercial demand. The bottleneck is space‑to‑ground links and ground-station access fragmentation, forcing data prioritization and latency tradeoffs. Near term fixes include on‑board/on‑ground processing, intelligent compression, edge computing, anomaly detection, and AI‑guided data prioritization with real‑time summaries. Longer term relief comes from Ka‑band and optical terminals, though deployment and access remain uncertain.

South Korea’s National Tax Service seized crypto from 124 high‑value tax evaders totaling about 8.1 billion won ($5.6M). A press release displaying Ledger wallets with handwritten seed phrases exposed the mnemonic recovery phrases, breaking offline storage. An unknown actor used the exposed seed to transfer about 4 million Pre-Retogeum (PRTG) tokens (worth roughly $4.8M). Recovery is unlikely; no clear suspect. The incident underscores self‑custody risks and how publicly shared seed data can erode security. It echoes a 2021 case where 22 BTC seized by police was drained after a recovery phrase leaked.

In 1960 Tove Jansson accepted Astrid Lindgren’s commission to illustrate the Swedish edition of Tolkien’s The Hobbit. She treated it as an adventure and deliberately diverged from her Moomin style, drawing up to 60 variations of each character and prioritizing landscape over character depiction. Some images were assembled from multiple drawings, relying on the 1960s printing to hide joins. The result, Bilbo – en hobbits äventyr (1962), emphasized atmosphere and dramatic scenes, but many readers found it too Jansson-like and not Tolkien-like, reducing its popularity. A 2022 book by Paul Gravett highlights the collaboration.

WebMCP introduces a standard to expose structured tools on websites so AI agents can act on your site with speed, reliability, and precision. It provides two new APIs: a Declarative API for HTML-form actions and an Imperative API for dynamic JavaScript-driven interactions. Use cases include customer support ticket automation, ecommerce configuration and checkout, and travel searches and bookings, all executed by agents on behalf of users. The project is in early preview; sign up to participate and access docs/demos. Licensing: content CC BY 4.0; code Apache 2.0. Updated Feb 10, 2026.

Philip Ball surveys Wojciech Zurek's decoherence-based program to explain how classical reality arises from quantum mechanics. Centered on entanglement and environment-induced decoherence, Zurek's quantum Darwinism shows that certain robust pointer states leave many identical imprints in the environment, yielding a consensus, objective classical world without invoking wave-function collapse. Ball argues this framework could reconcile Copenhagen and many-worlds interpretations and reduces the mystery of measurement to standard quantum theory. He notes remaining questions, such as what selects outcomes and how to test the theory further, but views Decoherence and Quantum Darwinism as a promising synthesis.

An EFF DeepLinks post argues the NSA’s mass surveillance relied on semantic tricks to mislead Congress. Senator Wyden asked DNI Clapper whether the NSA collects data on millions of Americans; Clapper answered “no” wittingly, a claim the piece says is false. It notes a Verizon order requiring all call records be handed to the NSA and explains DoD definitions of “collected,” which can exclude data that is intercepted and stored but not yet “collected” in usable form. Clapper characterized the terminology as “semantics” — a “least untruthful” reply. EFF urges a full investigation and congressional accountability.

Argues that C’s file API is best because memory-mapped I/O lets you treat files as memory: map a file, access data directly, with on-demand loading and OS-managed caching. It works for any datatype and scales to huge files without full reads or explicit serialization, ideal on memory-constrained systems. Higher-level languages force chunked reads, parsing, and separate databases; Python’s pickle is insecure. Endianness and mmap overhead exist, but the approach stays simpler and more scalable for large datasets.

In 19 adults with overweight/obesity, this randomized, within‑participant 28‑day weight‑loss trial compared higher‑fibre (HF) vs higher‑protein (HP) breakfasts, with meals apportioned 45/35/20 morning/afternoon/evening. Primary outcome: energy balance via weight change; secondary: gut microbiota and appetite via VAS. Results: both diets reduced weight, −4.87 kg HF vs −3.87 kg HP (P=0.002); HP breakfast yielded greater satiety (P=0.003). HF increased beneficial bacteria, including bifidobacteria and butyrate producers Faecalibacterium and Roseburia. Conclusion: breakfast composition affects appetite and gut health; HP boosts satiety, HF may benefit gut microbiota and weight loss.

Viv Groskop argues that modern life trains us to avoid talking to strangers, eroding a basic social skill and harming society. Through train and restaurant encounters, she shows how small, low-stakes conversations can connect us and ease social anxiety. Citing Esther Perel’s “global relational recession,” Gillian Sandstrom’s “small, humanising acts,” and University of Virginia research, she advocates brief, nonthreatening exchanges and easy exit options. It critiques performative social-media “talk to strangers” trends and urges readers to start conversations to preserve humanity.

Introducing gzpeek, a command-line tool by Evan Hahn to parse and display the metadata embedded in gzip streams. gzpeek reads the gzip header’s fields, including OS (varies by implementation and isn’t reliable), MTIME (Unix timestamp, 0–2106), FTEXT, XFL (compression level hint), NAME (original filename), optional COMMENT, and extra subfields. It’s written in Zig. The tool helps explore how different gzip tools set these fields and what they reveal about gzip metadata.

MicroGPT is a 200-line Python script that trains a tiny GPT from scratch on 32,000 names using character-level tokenization with a BOS token. It covers token and position embeddings, multi-head attention, RMSNorm, an MLP, residuals, and a final logits layer. Training minimizes cross-entropy loss via backpropagation implemented in a simple Value class, updated by Adam. Inference uses temperature sampling to generate names. The piece shows that the core loop—tokenize, embed, attend, predict next token, compute loss, backpropagate, update—remains the same as large models, differing mainly in scale and engineering.

Dada replaces Rust’s lifetime-based borrow checking with place-based permissions. When a variable is named, Dada creates references to the data’s place (not a lifetime); references are shallow copies, not pointers, and moves of borrowed data are allowed because ownership changes update the types (strong updates). Using forms like ref[self.list] String and ref[ch.name], you can borrow across fields and move the owner with give. The approach is illustrated with Character and Message examples and is currently modeled in the dada-model repo; the author envisions applying similar ideas to Rust, modulo its pointer-based &T limitations.

sas-audio-processor is a suite of 25 WAV audio tools (trim, time-stretch, normalize, eq, reverb, pitch-shift, key/MIDI extraction, etc.) exposed as MCP tools via DeclarAgent. Tools span Processing, Effects, Analysis, MIDI, and Composite workflows; all outputs are line-delimited JSON. Quick Start shows Claude Code/MCP integration with DeclarAgent and YAML plans. How it works: DeclarAgent reads plan files and runs sas-processor subcommands, returning JSON. The README covers CLI usage, building from source, and MIT license.
