The Origins of Vintage Comics Part 1

Key Points

• The article traces the printing origins of the classic vintage comic-book aesthetic in U.S. comics from the 1930s to the 1980s.
• It contrasts historical comic production methods with modern digital workflows and CtP printing technology.
• It argues that the old comics look resulted from a larger production system, not just cheap printing materials.

Branchless Rust: Making a Filter 4x Faster by Removing an If

Key Points

• Benchmarking showed that retaining 50% of elements was slower than retaining 99% in a Rust filter.
• Preallocating the output vector changed runtime only slightly, suggesting allocation was not the main bottleneck.
• The article explains the slowdown through CPU branch prediction and pipeline flush costs on unpredictable branches.

LLMs won't break symmetric crypto

Key Points

• Anthropic reported LLM-assisted attacks on HAWK and reduced-round AES, but not on full deployed AES.
• The article says LLMs may be useful for proof checking and formalizing cryptanalysis methods.
• The author argues established symmetric schemes like AES, ChaCha, SHA-3, and BLAKE3 remain secure against LLM-driven breakthroughs.

Nashville uses eminent domain to block data center near zoo

Key Points

• Nashville’s Metro Council voted 27-5 to advance eminent domain action against land slated for a DC Blox data center near the zoo.
• DC Blox’s proposed project covered 69,220 square feet on 23 acres and was expected to cost more than $700 million.
• The dispute aligns with a broader U.S. trend of zoning restrictions and moratoriums on data center development tied to rising AI infrastructure demand.

New Keyboard: Alicja v2

Do birds enjoy flying? Analysis of affect after flight in galah (E roseicapilla)

Key Points

• Galahs almost always chose to fly when given the opportunity.
• Flight was associated with increased appetitive behavior and more optimistic cognitive responses.
• Physiological stress-marker differences were not found between flight and non-flight days.

Quantego: A Family of Lego Models of IBM Quantum Computers

Key Points

• Quantego offers three LEGO models based on IBM Quantum System One and System Two hardware.
• Each model includes instructions, parts lists, and downloadable design files for BrickLink Studio and LDraw.
• The System Two page adds a browser-based quantum circuit simulator demonstrating H gates, CNOT entanglement, and Bell pair measurements.

Key Points

• Ship Safe is described as an open-source security scanner for coding agents.
• The public GitHub repository shows 776 stars, 96 forks, and 445 commits.
• The project includes directories for CLI tooling, benchmarks, documentation, checklists, and a Claude Code plugin.

Show HN: Wallfacer – A terminal session manager for Claude Code, and more

Key Points

• Wallfacer unifies AI coding session management across Claude Code, Cursor CLI, Kiro CLI, and Codex.
• It uses a read-only index of agent files plus a local SQLite database for titles, tags, projects, and search.
• The tool combines a full-screen TUI and a scriptable CLI in one binary, with both interfaces sharing the same session index.
