The day's tech, sifted: Nov 04, 2026

Wed, Nov 4

What matters today: Binance published its postmortem of the $6.3B theft: a tampered installer in June, then a fake hiring process in September. Yesterday it was the LinkedIn lure; today it is the full chain, and it starts with a Google ad. Canva is cutting 22% of staff while AMD and Super Micro post record data center numbers, and Google backed down on its schools policy after backlash.

AI / LLMs

  • Google reverses course on schools: After backlash, Google says schools can enable Gemini, Gemini Notebook and Search individually, per CNBC. Yesterday's rule tied Search to the AI features; the new one removes the all-or-nothing choice, though the early 2027 restrictions tooling is still ahead.
  • Claude Code's product lead leaves: Cat Wu, who led product for Claude Code and Cowork, has left Anthropic, per Business Insider; Thariq Shihipar, also of Claude Code, announced his exit last month. Two departures from one product team a day after the IPO filing's risk language is worth watching.
  • Revolut cuts coding-AI cost 90%: Revolut says it cut AI coding inference costs about 90% in under a year by making self-hosted GLM models its default over commercial tools like Claude Code, per The Register. Those are the company's own figures; the saving shows how fast "good enough and owned" competes with the frontier price list.
  • Leaderboard refresh: Per AlphaSignal's summary, Artificial Analysis rebuilt its six domain Capability Indexes to track hallucination control and agentic tool use, with Claude Opus 5.5 on top. Index methodology changes reshuffle rankings, so read the headline as one benchmark's view.

Devtools & Infra

  • Russia moves data centers underground: After Ukrainian drone strikes hit facilities run by Yandex, Sberbank, VKontakte and the finance ministry, Russian firms are looking to hide data centers underground, per Ars Technica. Rostelecom has discussed mines with Norilsk, and the Kremlin now requires owners to reserve capacity for emergency state needs. Cloud infrastructure has become a military target on both sides.
  • Jet engines for power: Data centers are turning to old jet engines as grid hookups lag, per TechCrunch. Power, not chips, is setting the build schedule.

Security & Privacy

  • Binance's postmortem: Binance says the intrusion started in June when one developer downloaded a tampered installer spread by a malicious Google ad, exposing details of its engineers. In September another engineer was courted through multiple rounds of fake interviews and handed a fake assignment to download; Binance also says an internal AI tool played a role. Delta from yesterday: the lure is now the second stage, not the first.
  • CrowdStrike's AI kill switch: CrowdStrike introduced an AI Kill Switch for halting AI agents that misbehave. It follows yesterday's Fiddler and Dreadnode purchases, so the vendor is now selling the control layer it just bought.
  • Postal Service watched protests: Records released in EFF's FOIA suit show the USPS internet Covert Operations Program (iCOP) monitored social media posts about protests in 2020 and 2021, across the political spectrum, with little documented oversight. One bulletin warned of possible violence while admitting it had no intelligence of specific threats.

Startups & Industry

  • Canva restructures: Canva says restructuring affects 1,271 people, or 22% of staff, as it merges product, growth and platform teams; the CEO calls it a "refounding" toward small teams, and some roles will relocate to hubs. The Age ties it to slowing growth.
  • Record AI-hardware quarters: AMD reported record $13.4B revenue, $8.5B of it data center, and guided to $17B next quarter and 80%+ growth in 2027. Super Micro reported revenue up 298% to $19.95B against $16.39B expected. Server demand is still outrunning forecasts.
  • Meta's $15B bond: Meta raised $15B in a dollar bond sale with up to $58B in orders, part of a $20B+ cross-border offering, per Bloomberg. Big Tech is financing the buildout with debt, and lenders are lining up.
  • Traversal raises $120M: The SRE agent startup raised $120M at a $1B valuation led by Kleiner Perkins, Redpoint and Khosla, per Forbes, for AI that troubleshoots outages at firms like American Express and Pepsi.
  • Nvidia's soft power: The Information reports Nvidia shapes customers and US chip policy informally; sources say OpenAI took no public stance on China chip exports to avoid angering it. Pairs with yesterday's China 49% cap report.
  • Pharma doubts AI cures: Drug company chiefs are skeptical AI will cure most diseases within a decade, per the WSJ (paywalled): no AI-designed drug has FDA clearance, and biology is the bottleneck.

Policy

  • California keeps its net neutrality law: California will accept $1.42B in broadband funding but rejects the federal condition that it stop enforcing net neutrality and rate rules, per Ars Technica. Legal fights with Washington and ISPs are likely, and the grants could be delayed.

Elsewhere

  • Steam review backlog: Valve says game reviews now take up to 12 business days instead of 3 to 5, because of a surge in submissions and re-reviews, and is changing its release checklist to cut them.
  • Nexus Mods requires AI disclosure: The PC mod site will make AI disclosure mandatory for new uploads.

Hacker News

The front page leaned on money and platforms: Nikkei's report that US tech giants' off-balance-sheet AI debt grew 90% to $3.2T in six months drew 314 points, a companion to Meta's bond sale above. Apple developer news drew the most discussion: Safari 27.3 adds an Adaptive Dark Mode, a post notes macOS 27 does not support CoreStorage volumes, and another dumped Apple's word list.

For builders, an essay asks how C++26 survives after a failed ballot, while The Internals of PostgreSQL and a math primer on generative AI were saved for later reading, and one user describes how they use AI as of October.

Threads

  • Attack chains start with a person: Binance's tampered installer and fake interview and the USPS surveillance records both show the weak point is the human step, not the protocol.
  • Debt funds the buildout: Meta's bond, the Nikkei debt figure on Hacker News, and AMD and Super Micro's record quarters are one story: spending flows from lenders to chips.
  • Power and war as limits: Russia's underground data centers and jet engines for US data centers both show physical constraints, not software, now gating compute.
  • Cheaper, owned models: Revolut's GLM switch, and Artificial Analysis crowning a frontier model, show the split between price pressure and top-end capability.
  • Backlash moves policy: Google's schools reversal, California's refusal on net neutrality and Nexus Mods' AI disclosure all follow public pushback on defaults.
  • Anthropic under strain: Cat Wu's exit lands beside the IPO filing's risk language from yesterday.
