The author adapts a smart button to temporarily disable network filtering for social media and other distractions.

They use a GL.iNet router running Adguard Home, Home Assistant, and a Zigbee smart plug/button.

A Home Assistant automation script turns off Adguard filtering for 15 minutes and enforces a one-hour cooldown.

A background script polls an $8 smart plug via its API to detect when it’s switched on.

When the plug is on, the script updates /etc/hosts to redirect distracting sites (Twitter, X, Instagram, YouTube, Reddit) to localhost.

The physical plug switch adds friction by requiring you to get up and turn it off to restore access, reducing reflexive visits.

Typst is a modern typesetting language combining Markdown-like syntax with a Rust-inspired scripting language, offering a comfortable and consistent writing experience unlike LaTeX.

Compile times in Typst are fast, with incremental builds allowing near-instant updates for content changes even in large documents.

The scripting capabilities let you embed data processing directly in the document, such as generating figures from TOML metadata without external tools.

A provision in the proposed Trump and GOP tax-immigration bill would have the General Services Administration seize and auction about 7,200 new USPS electric mail trucks and related charging infrastructure, undoing billions in EV investments.

USPS planned to spend $9.6 billion to buy 66,000 electric delivery vehicles—funded partly by $3 billion in taxpayer money and its own revenues—and to upgrade sorting facilities for low-emission vehicles.

Experts say auctioning the vehicles and infrastructure would bring negligible revenue due to low private-sector interest and non-resellable, buried charging equipment.

App to report idling commercial vehicles in New York City with timestamped video evidence.

Automatically fills complaint forms using AI (subscription required) or allows manual editing.

Generates required license plate and owner info screenshots from video.

Linux pipes implement a kernel ring buffer of 4KiB pages, causing double-copy and lock contention when using standard read/write syscalls.

Profiling with perf shows most time is spent in pipe_write, page copying, allocation, and synchronization.

The splice and vmsplice syscalls enable zero-copy transfers by inserting existing user pages directly into the pipe buffer.

Denmark's Ministry of Digital Affairs will replace Microsoft Office with LibreOffice.

About half of the ministry’s staff will switch this summer to enhance digital sovereignty.

The change is intended to reduce dependence on a few foreign software suppliers.

Git notes let you attach metadata to any Git object (commits, blobs, trees) without rewriting history.

You can add a note with git notes add -m and view it in git log alongside commit details.

Projects use notes to link commits to mailing list discussions, track review/test data, and log time spent.

Inspired by interactive exploded watch illustrations, the author aimed to create a tangible resin model of a mechanical watch movement.

Early resin casting (layered UV and two-part epoxy) faced issues: yellow tint, slow cure, visible seams due to refractive index differences.

Switched to suspending components on monofilament fishing line (nylon leader) with CA glue, matching resin’s refractive index and providing near-invisible support.
