The author, buried in USB cables, learns LEDs-only testers and macOS speed reports can mislead. The Treedix USB Cable Tester (2.4" color screen) proves the solution: it analyzes Data/Power, connected lanes, resistance, and eMarker for USB‑A/C on one side and USB‑C/mini/micro on the other. In testing, several cables claimed USB4 speeds (20 Gbps) but lacked SuperSpeed lanes, so PCs reported higher speeds than the cable could deliver. The tester revealed deceptive cables and let the author rate and sort them, developing a marking standard. Priced around $45; recommended; more B-side plugs would help.

An offline Kindle becomes a personal newspaper by pulling web articles into a Kindle-friendly format. The author tests Wallabag and Instapaper, finds Wallabag’s parser lacking, and adopts Readeck, which compiles saved articles into an EPUB from RSS feeds. He uses Calibre to convert EPUB to MOBI for Kindle. Then edits the book title/cover and archives read items. The workflow yields easy, glare-free reading on the sunlit E-Ink screen, but requires a computer to run Calibre; a native Android E-Ink tablet could be more convenient, and it even reduced time spent on traditional books.

Nestlé says about 12 tons (roughly 413,793 KitKat bars) were stolen after leaving its Italy production site for Poland; the vehicle and cargo are missing. The bars were to be distributed Europe-wide; if sold unofficially they remain traceable via batch codes. KitKat notes cargo theft is rising and aims to raise awareness.

This final installment profiles Don Lokke Jr.’s early 1990s ANSI “telecomics,” notably Mack the Mouse, a weekly conservative political cartoon published during the 1992–1995 BBS era. Lokke aimed to syndicate digital content to sysops, using cat-and-mouse allegory as Mack shifted from generic commentary to issue-specific critiques after Clinton’s 1993 inauguration. He built a library of hundreds of strips distributed via BBS networks and early online services, experimented with high‑resolution BIG graphics before pivoting to ANSI. By 1995 the Web eclipsed BBSs, Lokke’s work faded; he died in 2017.

The author argues that becoming an engineering manager is a skills decision, not a ladder choice. He switched from IC to management for impact— enabling a team to do more than he could alone— and found it sharpens communication by focusing on goals and intent rather than tasks. He describes the personal identity shift of managing former peers and the practical realities of flatter orgs and mixed pay. Still, management builds cross-team alignment, stakeholder communication, and ambiguity handling— transferable, sometimes even when returning to IC roles. If a relevant opportunity appears, take it and learn.

Daily Unfold generates three daily puzzles (easy 4x4 with one fold, medium 6x6 with two folds, hard 6x6 with three folds and two punches) deterministically from the date. It simulates folds by mirroring cells across each fold, then checks unfolded holes against punch positions. Difficulty uses a hand-tuned score with weights for off-center folds, hole spread, mixed axes, punches, fold count, and hole/grid size. If the generated three scores don’t satisfy hard>medium>easy, it rerolls the hard puzzle with offset seeds (up to 10 retries). Client-side only.

An online, interactive periodic table from PeriodicTableOfElements.org that lists all 118 elements with atomic numbers, symbols, and weights. It offers customizable views (color by category, block, state of matter) and displays properties such as electronegativity, atomic radius, ionization energy, and discovery year. Users can explore, compare elements, take quizzes, view a discovery timeline and periodic trends, and share results. The interface is multilingual, free for everyone, and includes navigation to Explore, Compare, and other features. © 2026 Periodic Table of Elements.

v2f (Verilog to Factorio) is a tool that lets Factorio players describe combinator circuits in Verilog and outputs JSON blueprints importable by Factorio 2.0. It exposes Rust and Lua APIs for in-code design, and can be used via a browser backend flow or locally with Docker/VSCode dev containers. The repository provides a frontend GUI, instructions to install and run (Lua script or CLI), and examples (RISC-V processor, DFF, ROM, ALU) with SVG renderings of designs. It uses Yosys for RTL generation and maps Verilog to Factorio combinators.

Cat-itecture argues current cat window boxes are human-vision-centric and expose cats to the outside with little control, ignoring cats’ acute hearing and risk-sensitivity. It proposes cat-friendly design patterns built from a cat’s-eye view: Gradation (more exposure levels), Sight vs Sound (separate handling of vision and noise), Sight then Sound (sound as safer, lower-stress modality), and Simple Use (static, easy-to-use mechanisms). The author suggests an improved two-box system (outer translucent with opaque band, inner opaque, connected by a porthole) plus a slider to modulate exposure. Cats manage exposure via risk compensation on an inverted-U scale.

Nostalgia for the 90s: a Pentium III 667MHz PC with 64MB RAM bought in 1999 for about $750, a scarce luxury for a family of three. The beige box demanded constant maintenance—dusting, fragile PS/2 pins, trackball cleaning, defragmentation, and slow blue screens with antivirus scans. Internet ran on 56Kbps with limited minutes; a 5MB song could take ~15 minutes. Web roaming sparked HTML tinkering, Photoshop experiments, and early gaming on CS/Unreal/Halo, plus piracy. The net connected a distant dad and, under the CRT glow, led to early design work that would later pay off.

Fraunhofer researchers develop adhesive-free sealing for paper packaging using laser modification. The PAPURE project unites IAP, IWS, IVV, and IWU to laser-treat paper so it forms fusible cleavage products that enable heat sealing without adhesives. Tasks include paper characterization, CO-laser surface modification, a sealing system, and a lab-scale demonstrator in Dresden for roll-to-roll production. Goal: ~10 packages/min by Sept 2026, with real-time seam quality monitoring and industry integration. Demonstrations planned at Interpack 2026 to advance circular, green packaging.

The go.mod go directive is the minimum Go version your module can be compiled with, not the version you use locally. Since Go 1.21, pinning a full patch (e.g., 1.21.0) is wrong: it becomes a viral minimum for all dependents, forcing them to upgrade. Do not decide others’ Go versions. Tools like actions/setup-go using the go directive to select toolchains is incorrect; use the toolchain directive or other methods. The default in go mod init to the latest version is a bad default. If code needs a patch, still avoid hard pinning; keep the minimum only.

Datahike replaces ETL with immutable databases as values stored in durable storage. A dereferenced connection yields a read-only snapshot; readers don’t coordinate with writers. Data is stored as a persistent, content-addressed B-tree in konserve, with nodes written once and shared across versions. A distributed index space loads nodes on demand, so reads require no server. Because databases are values and Datalog supports multi-input joins, you can join databases from different teams or backends in a single query, across time, with no data movement. Backends include S3, filesystem, JDBC, IndexedDB; browser-ready.
