The possibilities of zkSNARKs are impressive, you can verify the correctness of computations without having to execute them and you will not even learn what was executed – just that it was done correctly. Unfortunately, most explanations of zkSNARKs resort to hand-waving at some point and thus they remain something “magical”, suggesting that only the most enlightened actually understand how and why (and if?) they work. The reality is that zkSNARKs can be reduced to four simple techniques and this blog post aims to explain them. Anyone who can understand how the RSA cryptosystem works, should also get a pretty…

A prototype app called Pixeltone developed by Adobe Research and the University of Michigan showed the possibility of using voice control and touch for photo editing. The top comment on the YouTube video demonstrating the capability is this one, left by a viewer 12 years ago: “Why so much hate? It isn’t for the “real” photographer, but for my dad, that sometimes uses Photoshop; this is great.”The democratization of powerful photo editing tools has clear dangers, like the ease with which bad actors can use them to propagate disinformation and manipulate the truth. But most of today’s editing tools require…
This is a moment for America to show its decency, compassion and forgiveness.
OpenAI introduced ChatGPT Pulse, a proactive experience that compiles personalized, research-backed updates each morning. In preview on mobile and limited to $200/month Pro subscribers, Pulse surfaces topical cards built from a user’s chats, explicit feedback, and opt-in connected apps (e.g., calendar/email), shifting ChatGPT from a request-driven tool to a context-aware assistant. What Pulse Actually Does Under the Hood Each day, Pulse performs background research anchored to user signals: recent conversations, long-term interests, thumbs-up/down feedback, and data from connected apps where enabled. The output appears as scannable visual cards (briefs and deep links) rather than an infinite feed, designed for quick…
Take devices offline until patched: Analyst A large probing attack against Cisco devices was reported in August, noted Robert Beggs, head of Canadian incident response firm DigitalDefence. At the time, he said, it was suggested that this would be a prelude to a widespread vulnerability exploitation. “In this case, at least, the Cisco vulnerability was expected,” he said. “The detection of wide-scale probing of devices appears to be a reliable predictor of a following attack.” Because the vulnerabilities at the root of the attack can both be remotely exploited, affected devices should be taken offline until the patch is applied and verified to…
Universality by Natasha BrownNatasha Brown’s celebrated 2021 debut, Assembly, was a short, precise novel and a dissection of class and race that was shortlisted for several awards. In her follow-up she examines how identity politics is cynically deployed, satirising on the way cancel culture and the worlds of publishing and journalism. The story begins with a dubious article attempting to unravel a mystery involving an illegal rave, a missing gold bar and a banker. Soon the novel moves on to the fallout from the exposé, and the knock-on effect of the people affected by the crime. “It’s all enormous, nasty…

Ryanair has been accused of turning its back on elderly travellers after confirming plans to scrap paper boarding passes in favour of a digital-only system from November. The low-cost carrier, led by Michael O’Leary, will force the 40 million passengers who currently rely on printed tickets to switch to using its smartphone app from 12 November. Campaigners said the decision would isolate older customers, with millions lacking the skills or devices needed to navigate the change. Silver Voices, an over-60s lobby group, branded the move “disgraceful” and argued it amounted to discrimination against those who struggle with technology. Director Dennis…
