The Weekend Download, Edition 1

Welcome to The Weekend Download

Pour the coffee. This is the first edition of The Weekend Download, Rev-IQ's Saturday round-up of the most remarkable things that happened in technology this week. No hot takes, no stock tips, just five good stories, a number, one from home and something that made us laugh. Each comes with a single line on why it matters if you run, build or back a technology business.

This week an AI solved a puzzle that had stumped cryptographers for 25 years, Apple discovered people will happily pay US$1,999 for a phone that folds, and a car did a kickflip. Let's get into it.

The five

1. Claude cracks a 25-year cryptography mystery in under half an hour

Since the late 1990s, cryptographers have wondered where the "random" seeds behind the NIST elliptic curves (the maths protecting a large share of the internet) actually came from. This week Anthropic reported that Claude traced them to a standard C library random number generator, seeded with timestamps from 1997 and 1998. Anthropic is clear this is not a break, and if anything it makes a hidden backdoor much less plausible, a question that had been open for about 25 years (Yahoo Tech).

Why it matters: AI is moving from writing the email to doing the investigation, and the businesses that treat it as a research partner will find answers their competitors don't know to look for.

2. Apple's iPhone Duo sells out in minutes

Apple's first foldable, priced at US$1,999, sold out within minutes of preorders opening, with delivery dates pushed to late January 2027 (CNBC). Apple called demand "nothing short of extraordinary", and resellers were soon listing units on eBay for roughly US$1,800 above the asking price (Forbes).

Why it matters: a genuinely new product with a clear reason to exist earns pricing power, and discounting is rarely the answer to a value problem.

3. AI maps the chemistry of turning CO2 into fuel

Researchers at the Indian Institute of Science used AI to expand a model of how CO2 becomes methanol on a copper catalyst from 152 reactions to 9,389 (ScienceDaily). The bigger map lifted predicted CO2 conversion around 40-fold, bringing it into line with lab experiments for the first time, and revealed a pathway nobody expected.

Why it matters: when a model disagrees with reality, the problem is often what was left out, which is as true of a revenue forecast as it is of chemistry.

4. Proofpoint agrees to buy Varonis for US$6.3 billion

Thoma Bravo-owned Proofpoint will acquire data and AI security firm Varonis in an all-cash deal at US$49.75 a share, a 52% premium to the price before sale rumours began (Proofpoint). That values Varonis at about 8.4 times trailing revenue, and it is the largest cybersecurity acquisition announced so far in 2026 (SecurityWeek).

Why it matters: buyers are still paying strong prices for software that sits in the path of AI risk, which is exactly the split we wrote about in The five-year exit is over.

5. Waymo heads north to Toronto

Waymo is bringing its driverless ride-hailing service to Canada, with manually driven mapping cars on Toronto streets within days and first riders targeted for 2028 (Waymo). Local partner Element Fleet Management will run the fleet, and there is a catch: Ontario's pilot rules expire in October 2027 and the replacement hasn't been written yet (Electrek).

Why it matters: the technology is often the easy part, and a growth plan that assumes the regulator will keep pace deserves a contingency line.

Number of the week: 1,400+

Microsoft's October Patch Tuesday fixed more than 1,400 security vulnerabilities, its largest monthly release ever and more than it fixed in the whole of 2025, driven largely by AI-assisted bug discovery (Infosecurity Magazine). Microsoft is now proposing "risk cohorts" to help teams sort the pile (iTnews). The same week, research found 22% of UK security chiefs had called in sick or booked leave to avoid Patch Tuesday. We understand completely.

Why it matters: AI is accelerating the work as well as the tools, so prioritisation is becoming a core capability rather than an admin task.

One from home

Christchurch company ArcActive has installed its first commercial battery system, a 100kWh unit in a shipping container at Deakin University in Melbourne, through partner Origin Energy (NZ Herald). The technology reinvents the humble lead-acid battery with carbon fibre, holds enough power for about 50 homes, and a second unit is heading to a Sydney manufacturing site within weeks. The next goal is a 1MWh container.

Why it matters: some of the best ANZ technology stories start with a better version of something everyone thought was finished.

Just for fun

Tesla revealed its new Roadster this week, and the launch went well beyond 0 to 60 mph in a claimed 0.81 seconds. The car drove up an inverted ramp using fan suction, then flipped and landed using cold-gas thrusters, and later performed what designer Franz von Holzhausen called a "kickflip" over a Tesla Semi (The Independent). Production is targeted for 2028, and the flying trim is not approved for public roads (Paultan.org), which will disappoint anyone hoping to clear the M5 tunnel queue in style.

Until next week

That's the week that was. If something here sparked a thought, we'd love to hear it on LinkedIn. And if you'd like something a little longer for the weekend, our latest analysis lives at rev-iq.ai/insights.

Have a great weekend.
