Are We Legacy Computing Yet?
(arewelegacycomputingyet.com)
The article surveys Unicode’s “Symbols for Legacy Computing” character blocks (U+1FB00–U+1FBFF and U+1CC00–U+1CEBF) and tests which terminal emulators can render them correctly. It explains that many terminals rely on custom drawing logic rather than standard font glyphs, and that this affects how well the symbols connect and display as a coherent UI or graphic. Using a script that forces missing-glyph fonts, the author reports strong support in ghostty and vte-based terminals (with xtermjs supporting much of the main block but none of the supplement, and urxvt supporting essentially nothing).

Iranian-Affiliated Cyber Actors Exploit PLCs Across US Critical Infrastructure
(cisa.gov)
U.S. agencies warn that Iranian-affiliated actors are exploiting internet-exposed operational technology devices, including Rockwell Automation/Allen-Bradley PLCs, to disrupt operations. The activity involves manipulating PLC project files and altering data shown on HMI/SCADA displays, leading to operational disruptions and in some cases financial loss across sectors such as government services, water and wastewater, and energy. CISA advises organizations to remove PLCs from direct internet access, review related indicators of compromise, and monitor specific OT-related ports and overseas-origin traffic.

Rescuing old printers with an in-browser Linux VM bridged to WebUSB over USB/IP
(printervention.app)
The article describes how the author revived bargain-model old Canon SELPHY photo printers by building a cross-device web app that runs an in-browser Linux VM (v86) and bridges WebUSB to the printer via USB/IP. The app sets up CUPS with Gutenprint drivers inside the emulated Linux environment, uploads images, and routes the resulting raw print data back to the physical device. It also notes troubleshooting around bidirectional USB handling, CUPS image resizing, and Apple Photos/HEIC conversion, with plans to broaden support to other Gutenprint-compatible printers.

John Coltrane Illustrates the Mathematics of Jazz
(americanjazzmusicsociety.com)
The article discusses how John Coltrane’s “Coltrane circle” drawing—shared with Yusef Lateef in 1967—parallels the “circle of fifths” while reflecting Coltrane’s own musical innovations. It highlights efforts by physicist Stephon Alexander and other writers to connect Coltrane’s approach to mathematical ideas, alongside interpretations that frame the same structures as spiritual or religious experiences. The piece also notes that Coltrane frequently talked about Einstein and sought to express his method through philosophy and mysticism more than formal theory.

AI
The developer of the OldNYC photo viewer says AI-assisted geocoding and OCR have helped add 10,000 more historic photos to the site, with more accurate placement and better transcriptions. The update uses OpenAI (GPT-4o) to extract locations from photo descriptions, relies on OpenStreetMap-based datasets instead of Google’s geocoding, and rebuilds OCR with GPT-4o-mini for higher text coverage and accuracy. The post also notes a migration to an open mapping stack to reduce running costs and allow historical map styling, while outlining plans to extract more image information and expand to other collections or cities.

AI
A homeowner describes installing “Mabu,” a door-adjacent AI robot whose voice and actions are driven by an OpenAI-based chatbot, and then working through his unease about the risks. He raises privacy and security concerns common to smart speakers (criminal misuse of recordings, hacking, and data misuse), plus added worry for open-ended LLM conversations involving children. Because the robot is embodied, and because a mobile, connected machine could potentially cause physical harm if compromised, he keeps Mabu in a limited location and records only under tight controls, while anticipating that his concerns may grow as the technology matures.

AI
Google has open-sourced Scion, an experimental multi-agent orchestration testbed for running “deep agents” as isolated, concurrent processes. It uses per-agent containerization, git worktrees, and credentials to let multiple specialized agents work in parallel on shared projects while enforcing safety via infrastructure-level guardrails rather than agent-instruction constraints. Agents can run on local machines, remote VMs, or Kubernetes, and the release includes an example codebase (“Relics of the Athenaeum”) demonstrating coordinated agent collaboration to solve computational puzzles.
Good Taste the Only Real Moat Left
(rajnandan.com)
AI
The article argues that with AI and LLMs making “competent” first drafts cheap and easy, the real differentiator in tech is judgment and taste—especially the ability to diagnose what’s generic or misleading under real constraints. It warns that relying on AI mainly to generate and humans merely to select outputs risks turning builders into curators rather than authors who hold stakes and guide direction. The piece recommends using AI to generate options quickly, then training a sharper rejection vocabulary through critique and real-world shipping, while keeping authorship for decisions involving responsibility, genuinely new ideas, and choosing what to optimize for.
Is the United States a Terrorist State?
(factually.co)
The article says the United States is not listed by the U.S. State Department as a “state sponsor of terrorism,” and that the formal U.S. designation list currently names Cuba, Iran, North Korea, and Syria. It explains that critics argue some U.S. foreign policies and enforcement practices fit broader, moral definitions of “state terrorism,” but that this is a contested political and legal debate rather than a settled factual classification. It also notes that U.S. agencies generally treat terrorism as a foreign policy and criminal-law issue through established designation and sanction processes.

Wireless Festival has been cancelled after the UK government blocked Kanye West’s entry, withdrawing his visa permission. Organisers said refunds would be issued to ticket holders, following Prime Minister Keir Starmer’s view that West “should never have been invited” due to his past antisemitic and other controversial comments. The announcement comes after several major sponsors had already pulled back their support ahead of the festival’s planned July run in London.
12k Tons of Dumped Orange Peel Grew into a Landscape Nobody Expected (2017)
(sciencealert.com)
A Costa Rican experiment that dumped about 12,000 tonnes of waste orange peel on degraded land was shut down after legal action, but the buried nutrients helped the site regenerate into a dense forest over the next 16 years. Researchers comparing the area with an untreated control found higher soil quality, more tree biomass, and greater tree diversity, including strong carbon-sequestration potential. The study suggests the peel’s effects—possibly combined with reduced invasive grass and soil recovery—offer a cautionary but promising example for future conservation design.
