Google’s protection page blocks access to a YouTube video due to unusual traffic from the user’s network, likely automated requests or malware. To proceed, enable JavaScript and solve a CAPTCHA. The block may affect others on the same IP and will expire once traffic stops. If on a shared network, ask an administrator for help.

AI’s real power isn’t creating content but consuming and indexing your knowledge. By feeding my entire Obsidian vault into AI, I shifted from asking for new output to asking what I’ve already discovered. AI reveals patterns across years, links past notes, and surfaces forgotten context—e.g., performance issues precede tool complaints by weeks; design decisions reappear; connections between APIs and architecture. The result is faster problem solving, better decisions, and a personal knowledge database that becomes a competitive advantage. Start documenting for your future self and the AI that will remember it.

Esquire profiles Bob Rutan, Macy’s longtime Santa, and the secretive, sprawling Santaland world. Through interviews with former Santas and managers, it shows how playing Santa can save lives and give meaning, even as it destabilizes careers and families. Bob climbs to executive, then is fired amid ego clashes; his life frays—debt, estranged daughter—yet the red-suit myth endures as a source of redemption. A defining moment where two poor girls receive gifts from an elf underscores Santa’s real, forgiving magic.

Blog post criticizing Mozilla’s new CEO after a Verge interview suggesting Firefox could block ad blockers to gain about $150 million, though he says he doesn’t want to. The author argues this would betray Mozilla’s open-web mission and alienate the core, privacy-minded community that has kept Firefox popular, risking damaged trust and advocacy. It pleads for Mozilla to resist profit-driven moves.

P is a state-machine based language for formally modeling and specifying distributed systems. It models a system as communicating state machines and uses backend analysis engines (model checking, symbolic execution) to ensure the system meets its specifications. AWS uses P to analyze complex distributed services (notably S3) and to reason about core protocols; it also supports safe robotics research and was used to implement the USB driver stack in Windows 8/Phone. Benefits observed include forcing rigorous thinking, catching corner-case bugs, and speeding ongoing changes.

Tips for TLA+ modeling: start minimal, model only the slice of behavior; omit components if unnecessary. Write declaratively: specify what must hold, not how; minimize variables and derive new ones from existing state. Check for illegal global knowledge. Use fine-grained, guarded-command actions to expose interleavings; prefer TLA+ over PlusCal. Ensure you model failures, reordering, repair, reconfiguration. Write explicit TypeOK invariants as executable docs; craft tight invariants and progress properties; test by sabotaging invariants to ensure meaningful behavior. Separate model from model checker; tune cfg for bounds and symmetry; view the spec as a communication artifact.

Caroline Ellison, former Alameda Research CEO and ex-girlfriend of Sam Bankman-Fried, has been moved from federal prison to community confinement (home confinement or a halfway house) after about 11 months of a two-year sentence. Transferred Oct. 16 from Danbury, she remains in federal custody with a projected release of Feb. 20, 2026. Ellison testified as a star witness in Bankman-Fried’s trial about siphoning customer assets. The judge praised her cooperation but still imposed prison time. Bankman-Fried is serving 25 years and appeals.

Plastic Soldier Review's Annual Production analyzes soft plastic figure releases since the 1960s, using site reviews as data and excluding hard plastics, resins, reissues, and low-quality copies. It traces a history from Airfix’s 60s dominance, Atlantic and Matchbox peaks in the 70s, to a late-70s decline, Esci’s 80s dominance, and a 1990s resurgence led by HaT. The 2000s saw sustained growth with many new firms; 2006 and 2009 mark peaks (>100 and >140 sets). 2010–2013 remained high, 2014 quieted, then smaller producers and Eastern Europe drove output. 2022’s Ukraine war cut supply; 3D printing could reshuffle the future.

The article demonstrates how to magnetize an N48SH permanent magnet in Ansys Maxwell using its datasheet. It digitizes the N48SH B-H demagnetization curve with SheetScan, creates a custom initial BH curve, and defines a new material “N48_Unmagnetized.” A two-step linked magnetostatic analysis magnetizes the PM with a two-coil setup and then computes its final state, followed by validation against Maxwell’s built-in N48SH. The final operating points nearly match, validating a datasheet‑based, generalizable workflow for magnetizing permanent magnets.

Explores how Windows clipboard text conversions between Unicode, ANSI (CF_TEXT), and OEM (CF_OEMTEXT) depend on CF_LOCALE derived from the active keyboard layout. It shows that copying Hebrew text can yield correct results if read as Unicode, but reading as CF_TEXT may translate to 1252 on US systems, causing mojibake if the reader uses a different code page. After introducing activeCodePage, different apps can pick different code pages, creating mismatches. The post includes experimental code and foreshadows deeper investigation in the next installment.

VA Linux was a startup that IPO’d December 9, 1999, with stock jumping from $30 to $239, raising $132 million, a $9.5 billion market cap, though it hadn’t profit yet. Founded in 1993 as VA Research by Larry Augustin, it sold Linux-preinstalled PCs and once held ~20% of the Linux hardware market; etoys.com was a customer. The model faded as Dell/HP could offer Windows or Linux on similar hardware, and Linux hardware support improved. VA Linux abandoned hardware in 2001, becoming VA Software, then SourceForge, then Geeknet. GameStop bought Geeknet in 2015 for $140 million. It survived 16 years.

Tesla reported an eighth Robotaxi crash in Austin in October 2025 to the NHTSA under a Standing General Order. The incident adds to a high Robotaxi crash rate, roughly one crash every 40,000 miles—ten times the average US human-driver rate (about one per 500,000 miles)—even with a human safety supervisor present. Tesla plans to remove safety monitors from the Austin Robotaxi fleet, prompting concerns about safety; Musk claimed removal would occur within weeks, and the company has begun testing without a supervisor. Electrek notes redactions in crash narratives and contrasts with driverless Waymo data.
