An owner of a digital marketing agency analyzed email history dating back to 2010 to identify patterns in client terminations. The findings suggest that when the purchaser and point of contact are business owners, they are more likely to become difficult clients, including cases involving threats of legal action. The author, who has run a business for over 20 years, describes this as a recurring pattern and urges kindness toward other business owners.

Utah's Online Age Verification Amendments, Senate Bill 73, take effect May 6, making Utah the first U.S. state to hold websites liable for users who mask their location with VPNs as part of age verification. The law defines a user as being in Utah if physically located there, regardless of VPN or proxy use, and bans websites from sharing instructions to bypass age checks. Critics, including VPN providers and privacy advocates, say the measure is technically flawed and could unduly burden sites or affect legitimate privacy use.

The piece argues that security through obscurity should not be relied on alone but can be a useful extra layer in a defense-in-depth strategy. It cites examples such as WordPress table prefixes, the CS:GO debug symbols incident, and obfuscation practices used by Google, Netflix, and Riot Games to illustrate how obscurity can raise attackers' costs. It also invokes Kerckhoffs's principle and notes that, while AI may eventually deobfuscate, obscurity remains valuable as a ongoing hurdle.

After moving his site from SiteGround to Bluehost for cost and uptime reasons, the author states WordPress no longer fit his archive-focused workflow. He rebuilt with Yapress, a markdown-first, static publishing setup that stores content as files, enables local search and explicit taxonomies, and preserves old URLs through the migration. He notes trade-offs such as losing built-in comments and subscriptions, and argues platforms should offer a path that is genuinely better than building from scratch.

At Laguna Seca on May 3, Porsche Penske Motorsport will race two Porsche 963s in a historic Apple Computer-inspired livery based on the 1980 Porsche 935 K3. The wrap marks the 75th anniversary of Porsche Motorsport and the 50th anniversary of Apple, reviving the original Apple color scheme seen at Le Mans in 1980. The No. 6 entry will be driven by Kévin Estre and Laurens Vanthoor, while the No. 7 entry will be driven by Julien Andlauer and Felipe Nasr.

Alert-driven monitoring argues that alerts are the core output of infrastructure monitoring, guiding thresholds from service behavior rather than dashboards. It cautions against starting from metrics because that can produce noisy alerts, and it prescribes a zero-tolerance policy for false alarms along with a process of continual improvement, including weekly reviews, pruning, and root-cause analysis to strengthen alerting over time. The goal is to make alerts actionable, reduce alert fatigue, and improve early failure detection.

JPL engineers ignited a lithium-fed magnetoplasmadynamic thruster prototype, achieving up to 120 kilowatts—the highest power level recorded for an electric propulsion system in the United States. The February 24, 2026 test, conducted in JPL’s CoMeT vacuum facility, was publicly announced by NASA on April 28, 2026 and is part of a broader Space Nuclear Propulsion program aimed at developing a megawatt-class system for crewed Mars missions. The program notes that no MPD thruster has flown in space to date.

Visual Inbox Tools compiles public email archives into visual networks and timelines. It highlights three datasets related to Musk v. Altman: 74 emails from 2015–2019 involving 12 people (LessWrong OpenAI), 57 emails from 2015–2025 involving 37 people (CourtListener), and 737 emails from 2000–2002 involving 17 people (the Enron Executive Inbox). The datasets overlap on founding-era emails and are downloadable as a single JSON file with full provenance.

Europe’s Copernicus Sentinel-1 radar constellation is now at full capacity with Sentinel-1D entering full operational service after its in-orbit commissioning. The quartet builds on Sentinel-1A (2014) and Sentinel-1B (decommissioned in 2022), with Sentinel-1C joining in 2024 to restore four-satellite coverage and continuous, all-weather radar imagery for disaster, ice, land-deformation, deforestation and flood monitoring. The mission seeks an unbroken two-decade data record and includes debris-reducing separation mechanisms on Sentinel-1C and -1D, with ESA planning Sentinel-1 Next Generation.

A 31-year-old Swiss man, Jonas Lauwiner, has claimed about 117,000 square metres of land across Switzerland by exploiting a rule that allows ownership of ownerless land, acquiring 148 plots including 83 roads. He has built what he calls an 'empire', charging maintenance fees and selling rights related to construction near roads, prompting cantons to consider tighter rules amid criticism from local officials that the move exploits the system. Lauwiner says the title of 'King of Switzerland' was media-created and he is not a sovereign.

The article argues that the petroleum system is entering a more volatile decline phase as electrification reduces long-term oil demand and producer incentives shift. It notes the UAE’s exit from OPEC+ as a signal that flexibility and volume may be valued over cartel discipline, and it links historic shocks to current instability, including the Strait of Hormuz disruption. It also points to rapid electrification in transport, especially in China, as a driver of changing demand patterns, with the IEA calling the current crisis the most severe oil-supply shock in history.

Morgan Housel argues that everyone should write because putting thoughts into words reveals and tests ideas that live as gut feelings. Writing helps organize thinking, expose biases, and clarify why people make career or investment choices. He suggests practicing writing through journals, manifestos, or plans, noting that the process itself yields deeper understanding even without publishing.

The piece examines 'specsmaxxing'—the practice of writing software specifications in YAML to guide AI-driven development—and introduces Acai.sh, an open-source toolkit for spec-first workflows. It describes a feature.yaml spec format, a CLI, and a web dashboard that reference requirements by ACIDS (Acceptance Criteria IDs) and track their status across implementations. The article also discusses the motivation to document requirements and outlines steps to specify, ship, review, and iterate on features.

Japan’s Defense Ministry said the Japan Maritime Self-Defense Force has begun using the AirKamuy 150, a low-cost cardboard drone developed by AirKamuy, as an expendable aerial target. The drone costs about $2,000 to $2,500 per unit, travels roughly 50 miles, can stay aloft about 80 minutes, and can carry up to three pounds of payload. It is prefab and flat-packed, enabling about 500 units per standard shipping container, with potential swarm and limited-mission uses such as reconnaissance or decoys.

Bhatti is a self-hostable orchestrator that runs real Linux virtual machines via Firecracker on user hardware, with each VM having its own kernel, filesystem, and network space rather than containers. It snapshots entire VM state—memory, processes, file descriptors, and connections—and can resume from snapshots, while idle VMs pause to free resources and wake on demand in milliseconds. The system supports per-agent sandboxes and per-PR previews, with a CLI that manages VM lifecycles, image handling, and TLS-enabled publishing of previews.

The Z80 is a binary-compatible upgrade of the 8080, with higher-level changes in instruction decoding and registers that broaden its capabilities while keeping some 8080 behavior. The article then contrasts the 8086 as a 16-bit successor with advanced memory segmentation and more flexible addressing, highlighting how it differs from the Z80's design. It also notes development toolkits for 8080 and 8086 and briefly discusses the 6800/6809 line and the 6502's place among these relatives.

The piece describes an experiment to compare how transactions behave under different isolation levels in MySQL and MariaDB using a new open-source tool called Monastery. It outlines a scenario with a shoes table where two concurrent transactions perform updates to left_shoe and right_shoe, illustrating potential dirty reads or writes depending on isolation level. The article frames the test in terms of standard anomalies and notes the approach aims to run across multiple databases.

C3 has historically used unsigned sizes, but this approach created bugs in loops, comparisons, and arithmetic when unsigned and signed values interacted. The author describes moving to signed sizes by default to reduce implicit conversions and simplify reasoning about code, noting that unsigned arithmetic can hide errors and that languages like Go and Java have adopted signed sizes. The article explains the motivations, the pitfalls of unsigned arithmetic, and the resulting simplifications in C3's codebase.

Connected devices with bio-feedback sensors, priced around twenty pounds, promise to learn user preferences and adjust responses in real time. These devices collect intimate biometric data—patterns of response, timing, and intensity—raising questions about where the data is stored, who can access it, and how securely it is handled. The article notes this data could enter the broader, largely invisible marketplace of personal information.

A browser-based tool runs Apple's SHARP in the browser using ONNX Runtime Web to convert an uploaded image into Gaussian splats and export a PLY file. The project uses Bun, React, and Vite, and notes separate licenses for SHARP's code and model weights; if you use the released SHARP weights, you must follow the model license. Model export to ONNX is performed via a Python script, and the app can run in development or be built for static deployment, with performance depending on browser support and available memory.

core.logic is a logic programming library for Clojure and ClojureScript that offers Prolog-like relational programming, constraint logic programming, and nominal logic programming. It contains an original miniKanren implementation and references related work, with the latest stable release listed as 1.1.1 and dependency information for Maven, Leiningen, and CLI. The project notes its differences from core.unify and mentions YourKit profiling under the EPL license.

Systemd-manager-TUI is a terminal user interface application for managing systemd services. It supports viewing logs, listing services, inspecting properties, editing unit files, and controlling service states (start, stop, restart, mask, unmask, enable, disable) via D-Bus, with Vim-like navigation and the ability to switch between system and user units and to filter by running status; the project is open-source under the MIT License with installation options across Debian-based, Red Hat-based, Arch, NixOS, and cargo-based builds.

Dozens of care homes and hotels in Japan tied to one operator have shut down following a nationwide expansion since 2020, with at least 24 facilities closed or out of service. Investigations indicate a model linked to visa acquisition for Chinese investors, and the Choshi Hotel New Daishin remains closed after a 2025 suspension.
