Shows securing X11 apps by running them in an unprivileged LXC container on Arch Linux. Steps: install lxc/lxcfs, enable lxc-net, and create a container (www) with user mappings from /etc/subuid/subgid; use a Debian image, add a www user, and configure X11 access by mounting /tmp/.X11-unix and a container-specific .Xauthority while exporting DISPLAY and XAUTHORITY. Optional GPU and PulseAudio through /dev/dri and a PulseAudio socket. Start the container and run Firefox inside. Result: GUI app is sandboxed; blast radius limited, but sockets/holes remain; tighten with seccomp/AppArmor if desired.

Web MIDI meets 8-bit vintage synths: modern browsers and CPUs outpace 1983 gear, causing buffer overflow when sending SysEx data. The fix is software flow control, chunking SysEx messages with delays to let the DX7's 2 MHz CPU write blocks to RAM. Data formats vary by vendor—DX7 uses 4104-byte SysEx blocks, Juno-106 requires manual prompts, Korg M1 uses 7-bit packed data—necessitating custom parsers. Browser security requires user permission; some browsers block Web MIDI entirely. knob.monster positions as a browser-based SysEx librarian and cloud backup for vintage hardware, supporting many models.

Europe faces housing shortages that are worse than America’s, driven largely by land-use restrictions and suburban zoning. The essay argues Europe has little YIMBY-style debate, though Americans have a large movement with advocacy groups and research. Zoning was invented in Europe and has long protected suburban villa-style districts, as seen in Berlin’s 1905 plan and Britain’s enduring green belts. Densification is constrained, but outward expansion alone cannot close the gap. NIMBY resistance in Europe is latent, partly due to cultural emphasis on cities and less racialized zoning history. To solve shortages, Europe should reexamine zoning and consider American ideas.

GLP-1 drugs like Ozempic, beyond weight loss, may improve mood via the gut-brain axis. In mice, GLP-1 analogs caused weight loss and reversed depression-like behavior, but the antidepressant effect vanished in germ-free animals, implicating gut microbes. Researchers found enrichment of Lactobacillus delbrueckii, which GLP-1 drugs promote to produce endocannabinoids that dampen stress responses. Transferring the treated mice’s microbiota to depressed mice alleviated symptoms, and L. delbrueckii alone had an antidepressant effect. Different GLP-1 drugs have varying microbiome impacts; live ferments like yogurt may help via similar microbes.

Helen Lewis challenges the Galápagos paradise myth, arguing Darwin’s insight grew from empirical observation, not a sudden epiphany. The Beagle spent five weeks across four islands, yet Darwin’s theory drew on later work (finches, tortoises, and other fauna) and on Malthus. The Grants’ decades of study on Daphne Major refined ideas of rapid natural selection. Today, conservation and tourism shape the archipelago, with biosecurity and biocontrol efforts underway to curb invasives. Darwin’s legacy persists as a sober, curious empiricist who saw humanity as part of nature.

Sarah Wynn-Williams, Meta’s former director of global public policy and author of Careless People, sued Meta in Northern California federal court, alleging the company tried to silence her via a non-disparagement severance agreement and an emergency gag order. She says Meta surveilled her for over a year—attending events and photographing her—to ensure she said nothing about Meta or the book. Meta says she violated the agreement and that the memoir contains inaccuracies. Wynn-Williams seeks to lift the arbitration order and void the severance deal; Meta seeks damages for alleged violations.

Adrafinil is a macOS menu-bar app that keeps your Mac awake only while AI coding agents are actively working, including when the lid is closed. It blocks sleep via a privileged helper and user-space daemon with reference-counted assertions, waking only during agent sessions and releasing when work finishes. It supports 9 agents via hooks, timeboxed holds, and MCP, with <50ms CLI round-trips. Architecture includes Adrafinil.app, AdrafinilDaemon, AdrafinilHelper, and AdrafinilShared. Requires macOS 26.4+, admin rights for install. MIT licensed.

A Claremore, Oklahoma man, Darren Blanchard, was arrested for trespass after speaking a few seconds past a three-minute public-comment limit at a February city council meeting about Project Mustang, a 300-acre data-center campus. Video shows the arrest occurred as he sought to submit documents; footage cost disputes emerged (initial $1,750 quote, later $120). The case underscores tensions between public input and fast-tracked development terms, with concerns over water use, farmland loss, and tax incentives.

Life Magazine’s October 1967 piece, summarized here, asks if a learning machine could “think” like the human brain. It portrays the brain as a hierarchy of computers, with the retina acting as a preprocessor and neurons forming complex feedback loops that produce unified perception. A true supercomputer would require vast hardware and still lacks a wiring diagram; even with one, programming would be enormously difficult. A veteran programmer quips that teaching such machines could take decades and still fail, with possibilities of mislearning (e.g., 2+2 yielding 5).

A landmark review finds screen time for babies and toddlers under two linked to reduced caregiver bonding, less physical play, and slower language development, with potential impacts on sleep, eye health, and obesity. It cautions that no regular intentional screen time should occur before age two, though passive exposure is common; shared screen time might be misinterpreted as safe. The researchers urge urgent government rethinking of guidance and a baby screen-time risk assessment to support families. They warn current policies risk normalizing harmful use and call for better public guidance and support.

Revise launches full-history 'replays' in its editor, letting collaborators watch a document being written, rewritten, and reorganized in sequence—like a YouTube video. This provides a verifiable "proof of typing" of human authorship and signals Revise's aim to integrate AI into writing amid skepticism toward AI detectors.

Videx VideoTerm made the Apple II a serious business machine by adding 80-column output. Part 1 covers its hardware: the MC6845 CRT controller and why slot 3 is special (SLOTC3ROM/INTCXROM ownership enabling 80-column firmware). The card uses 2KB VRAM for an 80×24 grid, mapped through I/O at C0B0–C0BF; it has a 256-byte slot ROM (C300–C3FF) and a 2KB expansion ROM (C800–CFFF) with a 512-byte VRAM window at CC00–CDFF. CardCat identifies the firmware. FPGA emulation folds the board into Gowin RAM and uses XOR to merge inverse/cursor. Part 2 will cover rendering and Pascal boot hang.

Fox Ellison-Taylor argues traditional software jams are broken and explains Hack Club’s alternative. The plan uses Hackatime to track actual coding time and allocate prizes, scaling payouts with participation to reduce reliance on external sponsors. To improve quality, the approach calls for better judges, clear expectations (avoiding AI-wrapped projects), and giving participants time to produce solid code. Prizes are tied to an hour-based model with transparent estimates that can adjust to budget. Teens can join at radish.hackclub.com; contact [email protected].

IP Crawl is a beta 'living atlas' of open webcams discovered on the public internet. It lets users browse, filter, and watch live feeds from thousands of cameras worldwide, with no login required. It also offers an 'Am I Being Watched?' check to see if a nearby camera is exposed. The results show live cameras from cities such as Tulsa, Rotterdam, Como, Vienna, New York, Plymouth, Hayward, and more, with 1–24 of 14,131 items listed.

Despite the IMO pausing its Hormuz evacuation plan after the Ever Lovely was struck, ships continue through both the southern (Omani) and northern (Iranian) lanes. The IRGC Navy says only the northern route is legitimate. Secretary-General Arsenio Dominguez seeks guarantees that vessels won’t be targeted; Oman–Iran talks ongoing to secure assurances. In the plan’s short life, about 115 vessels and ~2,500 seafarers exited, with several ships turning back or switching routes, while others completed transits. The situation remains unsettled.

An experimental 'Town Square' lives at the bottom of pages: live visitors appear as stick figures, you see what article others read, move around, and send ephemeral messages. There are no accounts or persistent chat histories—the messages vanish when users leave. To make it easy for others, the author open-sourced Town Square and launched a public server so sites can add it without self-hosting (repo: https://github.com/cauenapier/TownSquare/); you can also register your site. Future ideas include more props, improved chat, and linking neighboring sites to form a Webring. Feedback welcome.

IEEE Spectrum reports Princeton researchers show AI can design RFICs, the 'dark art' of high-frequency chip layout. Using reinforcement learning and inverse design, AI creates architectures and electromagnetic passives from scratch, not just optimizing human templates. An AI emulator replaces heavy electromagnetics simulations, predicting scattering parameters in milliseconds, and diffusion models help make designs more interpretable. Early results include a millimeter-wave power amplifier with record efficiency. While promising, AI designs require verification and data-sharing ecosystems; open collaboration could accelerate future RFIC development.
