The piece argues that America’s anti-data center backlash stems from broader AI anxiety and a stalled national AI policy. Communities oppose centers over noise, energy, water use, and land impact, but treating data centers as the core issue misreads AI’s threats. Environmental objections are overstated; local bans won’t slow AI or govern its use. Instead, the author calls for a national, deliberative AI policy that expands human agency—via shorter workweeks, universal paid leave, worker control, or public ownership—rather than relying on local zoning fights.

Plasma is fully transitioning from X11 to Wayland. Plasma 6.8 will remove the X11 login session and purge X11-specific code in Plasma Shell, System Settings, and device configuration; XWayland remains for X11 apps. Plasma 6.7 is the last release to include an X11 session. KDE data show over 95% of 6.6 users on Wayland and about 76% overall Wayland adoption; no retroactive changes for older releases. Some workflows may need adjustment, but feedback is welcome to improve the transition.

Stephen Cass's May 2026 Hands On piece "Reviving Teletext for Ham Radio" describes recreating teletext as a ham-radio data mode. Using AX.25, he transmits 40x24 teletext pages; at 1,200 baud on VHF/UHF (about 11 seconds per page) or 300 baud on HF (≈44 seconds). Pages are repeated to fill gaps. He built Spectel in Python, aided by vibe coding and Anthropic’s Claude, and uses a Bedstead font to emulate teletext and references the SAA5050 chip. He invites ham partners to try HF experiments.

Meta repeatedly ignores an EU-backed appeals body over user bans on Facebook, Instagram and Threads. Appeals Centre Europe reviewed 4,600 ban cases but Meta supplied relevant content in fewer than 100. The BBC and others have documented numerous cases where users were blocked with no recourse. ACE found that in most hate-speech rulings platforms failed to enforce policies, and in about 3,000 reviewed cases the body disagreed with platforms 59% of the time. Meta did not comment.

FidoNet is a private, store-and-forward email network using dial-up modems, begun 1984; over 20,000 public nodes; originally MS-DOS, now across UNIX and Apple platforms. It uses zone:net/node addressing; power users can be points. Topology includes inbound/outbound hosts and zonegates; intercontinental routing via zonegates; Internet gateways via uucp/IP since 1991–92 (fidonet.org DNS). Gateways ~100; Usenet echomail exchanges. Technical standards: FSC/FTSC; FTS-0006 with zmodem; nodelist updated weekly with nodediff. Core components: BBS/NUA, Editor, Packer, NTA, Mailer, Nodelist Compiler. Policy-4 governance; IFNA dissolved after 1989 referendum. Widely used by NGOs in Africa and schools.

Argues that .NET Custom Attributes are a nightmare: arguments are stored as large fully qualified name strings in the metadata blob instead of compact tokens. Enum values, Type references, and nested types force expensive type resolution (assembly probing, type forwards) and complex FQN parsing. This bloats blobs, slows parsing, and makes resolution inconsistent across corelibs and references. The author suggests using metadata tokens or primitive element types would be far more efficient and notes backward compatibility preserves the current, inefficient design.

A guide to a Seattle surveillance walking tour that teaches spotting layered 'smart city' surveillance—from ubiquitous cameras and ALPRs to Amazon Go’s data practices, Acyclica Wi‑Fi trackers, Washington State Fusion Center, and NSA/AT&T peering hubs. Each stop details address, appearance, function, how it works, social importance, and discussion prompts about privacy, data retention, scope creep, and accountability. The route is about 1.3 miles and the article frames civil-liberties concerns and potential interventions.

Anthropic expands Project Glasswing from ~50 to ~150 partners across 15+ countries in critical infrastructure sectors to scan codebases with Claude Mythos Preview for vulnerabilities. Partners report over 10,000 high- or critical-severity flaws found so far. The initiative aims to shift from vulnerability finding to disclosing, fixing, and deploying patches, aided by Claude Security and related tools, and to scale cybersecurity collaboration among industry, open-source maintainers, and government. They foresee broad access for hundreds of thousands of organizations, with safeguards to prevent misuse as frontier models grow, plus a Cyber Verification Program and further expansions.

Eyeball is a precision-clicking game designed for mouse or trackpad use; touch input exists but is less accurate. It tracks stats like best, average, and streak, with rounds and reset options, and is built by Rory Flint.

The author describes upgrading a home-lab network from consumer gear to a 10G core using Mikrotik CRS305-1G-4S+ and TP-Link SG3218XP-M2 with an 8-port 2.5G switch, all managed locally (OPNsense firewall) with multiple VLANs and strict access rules. They abandoned Meraki/Cisco EOS for OSS/open hardware, addressed noise with Noctua fans, and case-modded cooling. Performance tests yielded ~9.4 Gbps on a 10G link with zero CRC errors and minor rx_missed_errors; NAS backups were bottlenecked by write speed, though sparse data dedup boosted efficiency. Power draw was around 20W for the switches. Conclusion: 10G improves reliability and openness is viable at home.

Paul McGowan’s idea: musicality isn’t added to an amplifier; it’s what’s left when you stop ruining it. Extending this, customer delight, curiosity, job satisfaction, and trust aren’t created by marketing or bosses—they’re what remains if you don’t ruin the experience.

Argues systemd timers are a superior, modern alternative to cron for scheduling on Linux. Timers are units that trigger services on calendar or relative time, with clearer paths, better logs, and more predictable environments. The post shows a minimal setup: roulette.service and roulette.timer, OnCalendar and enabling with systemctl, plus using systemd-analyze calendar to validate time expressions. It covers practical tips: ExecCondition, ExecStart paths, list-timers, randomized delays (FixedRandomDelay/RandomizedOffsetSec), WakeSystem, and Persistent for missed activations. Encourages reading systemd.time(7) manual.

Rene Zelaya built WhisperPad to reduce hand strain by locally transcribing speech on macOS and pasting into the active field. Apple rejected updates under Guideline 2.4.5 for using the accessibility API to inject text into other apps, though earlier versions did the same. He split WhisperPad into two builds: an App Store version that pastes only via clipboard (Command-V) and a direct-distribution version with full auto-paste. He uses Paddle for payments and Sparkle for updates; licensing is server-verified. The Store version remains accessible; the direct version ships outside the Store for full functionality.

IR imaging cannot resolve individual SRAM cells at 22 nm, but can bound total RAM by counting macros and data-path widths. This lets users verify RAM claims against fabrication and constrain hidden memory, reducing attack surfaces. While a few extra bytes could theoretically be hidden, overhead, architectural constraints, and IR/laser/interferometry measurements make such additions expensive and detectable; destructive SEM can confirm. The post dives into SRAM macro structures and alignment, and encourages readers to explore silicon with IR techniques.

Michael Burry questioned SpaceX and Anthropic valuations, saying neither is worth $1 trillion. In Substack chats, he argued SpaceX's S-1 shows no basis for a $1–2 trillion valuation despite rumors of a $2T target, noting $18.7B revenue and a $4.9B net loss. He also questioned Anthropic's $965B valuation, warning AI-model costs are expensive and computing power will be commoditized, making current demand signals unsustainable. He joked he would need to count to 1 trillion before paying that price.
