1. Hosting a website on a disposable vape Total comment counts : 58 Summary An author collects disposable vapes and finds a PUYA PY32F002B ARM microcontroller inside several models. Despite being labeled disposable, the device can host a tiny web server. Using semihosting with pyOCD, they bridge the MCU to a host via telnet, then route IP traffic with SLIP and a Linux slattach-like setup. They port the small uIP TCP/IP stack and its minimal HTTP server, tweak the filesystem for ARM, and note alignment issues....

1. ChatControl update: blocking minority held but Denmark is moving forward anyway Total comment counts : 11 Summary error Top 1 Comment Summary The piece rails against repeated efforts to weaken or eliminate encryption, arguing they reveal ignorance of how encryption and online safety work. Despite years of debate, proponents ignore experts, risking a future with less privacy and safer communications for fewer people. It also criticizes age-verification schemes, saying they push sensitive traffic onto cheap or free VPNs that may be state-controlled, which could undermine safety....

1. An Open-Source Maintainer’s Guide to Saying No Total comment counts : 0 Summary Maintaining OSS requires saying no to good ideas to preserve vision and coherence. Establish a mental model of the project, document why it exists, and let process align contributions with philosophy. LLM-generated code worsens signal-to-noise as unsolicited PRs bypass discussion. A good PR can come, but maintainers should push back unless it matches the project’s philosophy. Contrib modules can isolate non-core functionality, reducing long-term maintenance risk....

1. UTF-8 is a brilliant design Total comment counts : 23 Summary UTF-8 is a Unicode encoding using 1–4 bytes per character and remains backward-compatible with ASCII for the first 128 code points. The first byte indicates the total bytes; continuation bytes start with 10. For example, the Devanagari letter अ (U+0905) is encoded in three bytes. A text like ‘Hey👋 Buddy’ needs non-ASCII bytes (13 total), while ASCII-only text is valid UTF-8 with 9 bytes....

1. Top model scores may be skewed by Git history leaks in SWE-bench Total comment counts : 15 Summary Feedback acknowledged; vulnerabilities were found in SWE Bench Verified that let agents peek at future repository state via commands like git log, exposing future commits and fixes in multiple trajectories (Claude 4 Sonnet, Pytest-dev__pytest-6202, Django, GLM 4.5, Qwen3-Coder series). These leaks reveal solutions or approaches ahead of time. Mitigation includes removing future repo state and artifacts (reflogs, branches, origins, tags)....

1. Oldest recorded transaction Total comment counts : 16 Summary An image of an ancient 3100 BC transaction log prompts the author to ask how far back modern databases can timestamp. Examining MySQL, PostgreSQL, and SQLite, they find MySQL cannot handle such dates; PostgreSQL and SQLite support the Julian calendar with a minimum date of 4713 BC. Dates older than that aren’t natively supported, prompting questions about workarounds (epoch, text, or a custom system) at the expense of built-in TIMESTAMP features....
