EU commissioners shut down air conditioning for employees, leave theirs on

POLITICO reports Brussels' Berlaymont HQ forced to shut down air conditioning on Friday during a heat wave, with cooling cut from floors 1–7. The 13-story building houses Commission President Ursula von der Leyen, 26 commissioners, and about 3,000 staff. While upper floors kept AC, lower floors faced heat; staff called the arrangement 'feudalism' and a 'disgrace'. Temperature inside on the 8th floor was about 25.7 C. The episode sparked debate on Europe’s limited AC use, with only ~20% of households having AC and energy strain noted in the Parliament.

County with 37 Data Centers Asks Schools to 'Conserve Electricity'

Henrico County, Virginia, home to 37 data centers with 17 planned, expects a 25% rise in electricity costs next fiscal year, adding about $5 million. County Manager John Vithoulkas emailed thousands of employees urging simple conservation measures—turn off lights and computers, close blinds, unplug unused devices, limit space heaters—to offset higher rates. Data centers, powered partly by temporary diesel generators, have sparked community concerns over water use, noise, and rising bills. Virginia recently approved rate hikes; officials argue these savings will fund services.

Scammers Sell Seeds for Exotic AI-Generated Flowers That Don't Exist

Scammers are selling seeds for exotic AI-generated flowers that don’t exist, using eye-catching AI images on eBay, Amazon, and Etsy. Common fakes include teddy bear sunflowers, rainbow roses, and other surreal plants; AI imagery often shows oversized blooms and a random grandma for scale. Some listings have sold thousands of units, with buyers reporting non-delivery or wrong plants. The practice risks wasted money and potential invasive species. Platforms say they enforce policies and remove fraud, but the scam remains widespread.

We moved our Bluesky data to Eurosky

Waag moved its Bluesky data from Bluesky’s infrastructure to Eurosky’s Personal Data Server (PDS) to gain control and enable migration, reducing platform dependence. A PDS stores a user’s account, posts, followers and interactions on a server of the user’s choosing, enabling decentralisation within the AT Protocol. Eurosky is a European, privacy‑focused PDS provider. The move critiques Bluesky’s centralisation—though the protocol is open, Bluesky dictates features, moderation and monetisation, backed by VC funding. Waag remains active in decentralised networks via its Mastodon instance waag.social (~500 users) and invites others to migrate.

Claude Code Is Steganographically Marking Requests

Claude Code hides system-prompt markers that encode a classifier based on ANTHROPIC_BASE_URL, timezone, and host. It stealthily alters the system date in the prompt: changing the apostrophe and the date separator (YYYY-MM-DD to YYYY/MM/DD) under certain conditions. The marker is embedded in the prompt and only visible as a normal date. The trigger checks ANTHROPIC_BASE_URL against domain and lab-keyword lists decoded from base64 XOR 91; lists include many Chinese/AI domains. In typical setups it stays inactive, but it can be bypassed by changing base URL, hostname, or patching the binary. The author calls for explicit, transparent telemetry.

The labor share of income in the US is at its lowest post-war level

The Post–COVID Decline in the Labor Share notes that the labor share—the share of income going to workers—has fallen to an all-time postwar low, about 1.6 percentage points below pre-pandemic. The analysis finds the post-COVID drop is not a new phenomenon but follows the same cyclical patterns seen in earlier recessions. A shift-share decomposition shows the decline arose from within-industry changes rather than sectoral reallocation, which spikes briefly at COVID onset but does not drive the fall. Thus, the post-COVID decline mirrors prior episodes and is not uniquely different.

Supreme Court upholds broad conception of birthright citizenship

Supreme Court upholds birthright citizenship, rejecting Trump's order to deny citizenship to children born to people in the U.S. illegally or temporarily. In other rulings, the Court: allows states to ban transgender girls and women from school and college sports under Title IX; strikes down limits on how much political parties can spend in coordination with candidates; holds presidents may fire agency heads at will (with Fed governor Lisa Cook allowed to stay for now); and lets states count late-arriving mailed ballots.

Have You Restarted Your Computer This Week?

An author ritualizes restarting their Mac on Saturday mornings, even though restarts aren’t usually needed. They enjoy the ritual of closing apps, dismissing warnings, and force-quitting stuck processes. Because most work is saved to the cloud (OneDrive) and in Emacs, little is lost, so the reset feels safe. They view rebooting as a quick way to fix problems and as a pause to grab a coffee. Have you restarted this week?

Words Are a Byproduct of Consciousness. For LLMs, It's Backwards

Humans produce language from consciousness; words are the skin, ideas the core. LLMs invert this, predicting the next word without underlying concepts. Tracing tech history—from writing and printing to the internet and Transformers—the piece argues this reversal marks a shift: with AI, everyone can build, and value comes from consistency and effective marketing amid rampant noise. Jobs may evolve; coding is easy compared to thinking like an engineer. AI content could erode context, but the era also opens new ways of thinking and unforeseen opportunities.

Beware, Claude Code deletes >30 day old transcripts. Anthropic won't fix it

A GitHub issue reports Claude Code silently deletes transcripts older than 30 days because cleanupPeriodDays defaults to 30. On startup it removes ~/.claude/projects/<project>/.jsonl without first-run disclosure or config exposure, causing loss of months of history. Repro: use Claude Code >30 days without changing cleanupPeriodDays. Impact: reasoning trails and context are lost. Requested fixes: make the default non-destructive (disabled or long retention), disclose at first run, require opt-in for deletion, soft-delete to trash, and surface the setting in /config. Workaround: set cleanupPeriodDays to 3650 in ~/.claude/settings.json.

Looking Ahead to Postgres 19

Postgres 19 beta delivers broad, practical upgrades: core REPACK with CONCURRENTLY; more usable partitioning with MERGE and SPLIT; mature logical replication (sequence synchronization, ALL SEQUENCES in publications, EXCEPT support, better refresh behavior, automatic replica enablement); autovacuum gains parallel workers and smarter per-table scoring with new visibility via pg_stat_autovacuum_scores; SQL/PGQ introduces property-graph queries without leaving the relational model; COPY improvements (skip headers, ON_ERROR SET_NULL, JSON output, partitioned exports); quality-of-life SQL (GROUP BY ALL, IGNORE/RESPECT NULLS in window functions, INSERT ... RETURNING, FOR PARTITION OF) and broad performance/planner enhancements. Test against real workloads before GA.

Microsoft reveals why Windows 11 keeps saying a file is in use after closing app

Windows 'file in use' can persist after closing an app because Windows keeps file handles. Three main causes: antivirus scans holding a lock; a remote network device still referencing the file; or the file loaded as a DLL in memory, which doesn't show as a handle. To identify the culprit, use Sysinternals Handle (CLI) or Process Explorer’s Find Handle/DLL, or PowerToys’ File Locksmith. If you can't release the handle, rename the file and replace it later. The piece notes the long-standing nature of the issue and Microsoft’s acknowledgment.
