An overview of The Learning Company’s rise as a top maker of educational software (Reader Rabbit, Cluefinders, Oregon Trail) and its spectacular fall. The firm grew via innovative products but was undone by a succession of acquisitions and a price-cutting model under SoftKey, followed by Mattel’s ill-fated $3.5B takeover. Eighteen months later TLC was sold for $27M. The advent of the Internet and a shift away from CD-ROMs decimated the market, and the industry never recovered—though TLC’s brands live on in nostalgia and later media.

Maine’s baby eels, or elvers, have spawned a high-stakes black market that became a real-life crime drama in the mid-2010s, with enforcement stings like Operation Broken Glass and elver rings trafficking millions. Eels fetch around $2,000 a pound and are mostly sent to East Asia. Joshua and Jack Viertel co-wrote The Glass Eel, a mystery about a Maine town pulled into illegal trafficking, reflecting a broader trend of elver-crime stories in books and TV (the Netflix show Bodkin). Local booksellers say readers want nuanced, less stereotyped Maine tales.

Robotopia is a 3D, first-person talking simulator from Tomato Cake Inc. that uses LLM-powered NPCs for emergent, dialog-free storytelling. Founders Tommaso Checchi and Coleman Andersen unveiled a stealth-built prototype, demoed at DICE and GDC, and secured funding after a post-demo pitch. The game blends procedural sandboxing with high-detail environments and “verbal combat,” avoiding traditional dialog trees. Players speak with NPCs through the spacebar and shape outcomes via creative dialogue. Tomato Cake plans community tools for building levels and robots; a trailer is out and a Discord is open for sign-ups.

Marcin Wichary's photo essay propels readers through a personal tour of his favorite tech museums, celebrating places where history, craft, and design meet—Taipei's National Railway Museum Park; Figueres' Museu de la Tècnica de l'Empordà; ACMI Melbourne; Berlin's Computer Game Museum; Zwolle's Bonami; Helmond's Home Computer Museum, and more across Europe, the US, and beyond. He prizes museums that blend rich collections with narrative, context, and delightful interactions, not just artifacts. He also offers critical examples like Utrecht's Railway Museum, The Hague's House of the Book, and the Benjamin Franklin Museum. Readers are invited to share favorites.

The post argues that abstraction design trades power for properties and hinges on system-boundary versus open-world considerations. It distinguishes three ways to represent new types: data (fixed schema, extensible operations), objects (fixed interface, extensible implementations), and abstract data types (sealed interfaces hiding constructors, extensible in both dimensions). The expression problem captures extending both variants and operations; full extensibility is hard and can lead to spaghetti code. Practical strategies exist (Object Algebras, a la carte, tagless final, dynamic languages). In practice, mix data and objects and make intentional design choices rather than seek universal solutions.

One Google engineering manager shares a simple habit: start all meetings at five minutes past the hour (or half past). The five-minute buffer prevents back-to-back meetings from overrunning, gives attendees a mental break, and creates social pressure to wrap up on time. The practice has spread organically across the org because it improves focus and reduces stress, even though it isn’t mandatory.

lcamtuf draws a surprising parallel between raster graphics and audio, applying downsampling and other transforms to both. Bucket averaging yields pixel art in images but creates metallic artifacts in audio; a rolling-average filter can blunt the distortion. Reducing bit depth causes hiss rather than squeals, due to high-frequency errors and DAC low-pass filtering. He plays with time-domain filters (delays, echoes, choruses) and frequency-domain tools (FFT, spectrograms) to edit sound and even images. To avoid edits’ discontinuities, he uses overlapping Hann windows, letting sin^2+cos^2=1 cancel attenuation. Provides simple code and notes about pitch-shifting limitations.

An issue on denoland/deno discusses an unofficial PyPI distribution of Deno for Python projects, asking if the Deno project should review or endorse it and potentially collaborate. It links to the PyPI package (deno) and a related project (denop). Opened Nov 12, 2025 and later closed (issue #31799). Community welcomed the idea but noted the distribution is unofficial.

Emma Freud uncovers a single begonia cutting, traced through a long line of gifts from Sigmund Freud to Kirsten Flagstad in the 1930s, who passed it to Sally Miles, then to Corinne Rodriguez, to Barry Walsh, to Tom Basden, who gave it to Emma. The plant becomes a living link to Freud’s exile to London in 1938, his Berlin roots, and his son Ernst Freud, architect of the first Mermaid Theatre. Emma visits the Freud Museum and her late father, aligning estranged family ties and turning the cutting into a symbolic heirloom she plans to pass on.

Security researcher disclosed that Flock Safety hardcoded an organization-wide ArcGIS API key across 53 public front-end bundles, granting access to the ArcGIS mapping environment and 50 private layers. The single credential, unauthenticated and not restricted by referrers or IPs, could be used across 53 endpoints to view data from about 12,000 deployments, including ~5,000 police departments, ~6,000 community deployments, and ~1,000 private businesses. The key enabled access to cameras, patrols, drone telemetry, 911 data, hotlists, CAD, and PII via FlockOS’s unified map. A separate unauthenticated token minting vulnerability remained unpatched for 55+ days. API rotated; risk remains.

Repogen is an alpha CLI tool that generates static repository structures for multiple package managers. It scans directories for packages, auto-detects package types, generates required metadata, and signs repositories with GPG/RSA keys. It can produce unsigned repos, perform incremental updates, and output static file structures served by web servers. Supports Debian/APT, RPM/Yum, Alpine, Arch Pacman, and Homebrew, with repository formats such as InRelease, repodata, APKINDEX, and more. Written in Go; includes Docker-based tests and GitHub Actions workflows.
