📣 Announcement



Jeff Dean Facts is like Chuck Norris facts, but for programmers (Jeff Dean is a legendary Google engineer)

Last issue's Jeff Dean Facts section had a small... formatting hiccup. Ironic, since Jeff Dean once formatted a hard drive by staring at it disapprovingly.

Unlike Jeff Dean, I occasionally ship bugs. But the issue is now fixed. Welcome to your new weekly feature!
🙈 Useless Fact of the Day

The most common name in Italy is Mario Rossi.
📰 News
AI-driven demand for memory is causing severe shortages, pushing up prices for GPUs, SSDs, and even hard drives. Manufacturers are favoring high-margin GPUs and big-name SSDs are scarce or expensive, while midrange cards and smaller drives remain relatively affordable—for now.
Mobileye is buying Mentee Robotics, a Shashua co-founded humanoid robot startup, for $900 million to launch “Mobileye 3.0.” It’s a pivot from pure automotive autonomy toward broader “physical AI,” leveraging its chip, software, and cash pipeline to enter robotics.
Microsoft is redesigning Edge with Copilot’s UI: rounded corners, new colors/fonts, Copilot-like settings and new tab page. This aligns Edge more tightly with AI features and may spread the Copilot design language across other Microsoft web apps and Windows.
Vast Space’s Haven-1, likely the first commercial space station, has slipped launch from mid-2026 to Q1 2027 but is structurally complete. It will launch uncrewed on Falcon 9, host short stays, and serve as a demo stepping-stone toward larger NASA-backed stations.
OpenAI’s latest model, GPT 5.2, is independently solving some Erdős problems and advancing proofs, often via tools like Harmonic and Lean. Mathematicians like Terence Tao see AI as systematically tackling “easier” conjectures, signaling AI’s emerging, credible role in frontline mathematical research.
Architect Julia Barfield proposes a £11bn, 14-mile tidal lagoon off Somerset to generate 2.5GW, helping power AI-driven electricity demand. The project includes leisure facilities, potential datacentres, marine farming, and aims to boost a deprived local economy, pending strong government backing.
Betterment suffered a January 9 breach via social engineering on third‑party platforms, exposing customer contact details and birth dates. Hackers sent a fake crypto “triple your money” message. Betterment says accounts and passwords weren’t accessed, but hasn’t revealed how many customers were affected.
An Austrian cow, Veronika, was observed using a broom in different ways to scratch various body parts, demonstrating flexible, multi-purpose tool use previously seen only in humans and chimpanzees. The finding suggests cows may be far more intelligent and innovative than assumed.
Mandiant released a public NTLMv1 rainbow table that lets anyone crack Net‑NTLMv1 admin passwords in under 12 hours on cheap hardware. Goal: give defenders proof NTLMv1 is dangerously weak and force organizations to finally disable this legacy protocol.
NASA rolled the Artemis II SLS rocket to Launch Pad 39B, staying on schedule for a possible February launch. The four-person crew will fly around the Moon, set distance and reentry speed records, and validate systems before a later lunar landing mission.
