Google worker charged with using internal data to make $1.2m on Polymarket • BBC News
Kali Hays:

A Google employee has been arrested for allegedly using his access to company information to successfully place lucrative bets on the prediction platform Polymarket.
The US Attorney for the Southern District of New York said it had charged Michele Spagnuolo, a Google engineer, with breaking insider trading laws because of several bets he placed through the platform.
Although Spagnuolo is an Italian citizen who lives in Switzerland, he was arrested on Wednesday and brought before a federal judge in New York.
Spagnuolo allegedly used information he had early access to through his work at Google, which is based in the US, to make bets that saw him rack up $1.2m (£894,330) in winnings.A spokeswoman for Google said the company was “working with law enforcement on their investigation” and that the employee had been placed on leave.
The internal information that was allegedly used was marketing material accessed “using a tool available to all employees, but using such confidential information to place bets is a serious breach of our policies,” she added.
A spokesman for Polymarket said the platform “worked closely” with authorities on the investigation. “Blockchain trading is transparent, traceable, and bad actors leave footprints,” the spokesman added.
…Spagnuolo did not respond to an email seeking comment. According to online profiles, he worked for Google for more than 12 years as an engineer focused on information security.
He started using Polymarket in 2024, and between October and December of last year, the US Attorney’s office said Spagnuolo placed $2.7m in bets related to Google.
By using internal information, he was able to make more than $1m in profits from those bets, it said.
The court papers said Spagnuolo’s most lucrative alleged Polymarket wins were correctly predicting who would and would not be the most searched for person on Google in 2025.

Can there be any doubt now that betting makes people do stupid things? And over such utter trivia.

The ghost who solved a theorem: Thomason, Trobaugh and a dream • Abakcus
Ali Kaya:
»
Robert Wayne Thomason was born in Tulsa, Oklahoma, on November 5, 1952. He earned his doctorate from Princeton in 1977 and built a reputation as one of the most formidable mathematical minds of his generation — a figure who held topology, algebraic geometry, and K-theory simultaneously in his head in a way very few could manage. Colleagues described him as looking like a beat poet, dressed always in black, with a pointed goatee.
By the mid-1980s, Thomason had fixed his attention on a central problem in algebraic K-theory: proving a localization theorem for schemes that did not require regularity — a condition that previous results, including those of Daniel Quillen, had demanded. For 15 years, the absence of such a theorem had blocked the field’s development. Thomason spent three years attacking it. He assembled nearly every piece. But one step refused to fall: he needed to show that perfect complexes on a scheme could be extended from an open subscheme to the whole scheme. The obstacle was the K₀ obstruction — a topological invariant that, for some perfect complexes, is nonzero, seemingly making such extension impossible. Thomason explored this avenue and concluded it was hopeless. He was stuck.
Thomas Trobaugh was Thomason’s close friend — described by Thomason as “quite intelligent, singularly original, and inordinately generous.” He died by suicide, a consequence of endogenous depression, sometime before January 1988. Then, 94 days after Trobaugh’s death, Thomason had a dream.
In the dream, Trobaugh’s simulacrum spoke a single mathematical sentence. When Thomason woke, startled, he was certain the idea was wrong. He had already proved to himself that this approach led nowhere. And yet the dream had been insistent enough that Thomason sat down and worked through the argument, looking for the gap he was sure was there.
“The direct limit characterization of perfect complexes shows that they extend, just as one extends a coherent sheaf.”
There was no gap. The idea was correct — not because perfect complexes extend directly, but because the insight pointed toward a deeper structure: by working in the right derived category, the obstruction could be circumvented entirely.
«
Famously, Kekulé inferred the circular structure of benzene (C6H6) in a dream. And this is complex maths in a dream. There are probably more examples, The common thread here is that Kekulé and Thomason knew the solution already – but not consciously. There are surely similarities with how LLMs can turn up ideas that are buried within their data and only become apparent because they’re adjacent in the n-dimensional space within which that data is organised.

IPL’s anti-graft unit warns against use of smart glasses in restricted zones • The Indian Express
Varinder Bhatia:
»
The IPL’s [Indian Premier League of cricket] Anti-Corruption and Security Unit (ACSU) has issued a fresh advisory to players and support staff in the ongoing edition of the T20 league, warning against the use of smart glasses, sunglasses and goggles equipped with communication and recording technology inside restricted areas on match days, The Indian Express has learnt.
Sources said the ACSU, which is responsible for monitoring integrity, preventing spot-fixing and enforcing security protocols in the league, has informed the BCCI that several companies are actively marketing and selling smart eyewear products to players and team personnel participating in the IPL.
According to sources, the ACSU flagged that these smart devices are capable of live-streaming, sending and receiving text messages, and making audio and video calls through mobile data or Wi-Fi networks, raising concerns over unauthorised communication and potential misuse during matches.
Under the IPL’s Player and Match Officials Area (PMOA) Minimum Standards, such devices have been classified as “Audio/Video Recording Devices” and “Communication Devices”.
The ACSU has reiterated that possession or use of smart glasses and similar wearable technology is strictly prohibited inside the PMOA. Players and support staff have been instructed to deposit such devices with Security Liaison Officers, along with their mobile phones and smart watches, before entering restricted zones on match days. Sources said failure to comply would amount to a breach of PMOA protocols and could invite penalties under operational regulations.
“With wearable technology becoming more sophisticated and concerns growing over covert communication methods, the ACSU’s latest crackdown underlines the league’s attempt to stay ahead of evolving integrity risks during one of world cricket’s most commercially significant tournaments,” sources said.
…On May 8, The Indian Express reported that the unit had flagged the presence of unauthorised persons in team dug-outs following which the BCCI sent an advisory to all IPL teams and called a meeting of CEOs of all franchises to remind them of the protocol.
Sources said the ACSU had specifically raised concerns about individuals attempting to loiter near dugouts and hospitality areas to initiate informal contact with players and support staff. Teams were advised to ensure that net bowlers, logistics staff, throwdown specialists and other temporary personnel remained within approved access protocols and did not carry unauthorised communication devices into sensitive areas.

The IPL is a colossal sports concern, and betting around it will be equally huge. Smart glasses are an obvious way to record things without appearing to record them. (Link via Joe S.)

Tardigrades reveal extreme heat-blocking survival trick while in “tun” state • Phys.org
Ingrid Fadell:
»
Tardigrades, also known as water bears or moss piglets, are tiny eight-legged animals that can survive in extreme environments, where humans and most other animals would die. This resistance to extreme conditions, including intense heat, very high or low temperatures, radiation and low oxygen levels is called “extremotolerance.”
A biological process that allows tardigrades to survive in extreme environments is anhydrobiosis. This is a reversible process via which the animals lose most of their body water and their metabolism temporarily stops, which in turn allows them to survive in dry environments. When tardigrades undergo this process, they curl up and enter what is known as a “tun” state.
Researchers at the Indian Institute of Science recently carried out a study aimed at better understanding how a species of tardigrade—called Paramacrobiotus sp. BLR strain—survives extreme heat while in the tun state. Their findings, published in the Journal of the Royal Society Interface, suggest that reductions in thermal conductivity are central to the survival of this species at high temperatures and under extreme heat.
…The results of this study suggest that the ability to survive extreme temperatures is supported not just by biochemical, but also by physical processes. Further research could try to validate the team’s observations across a wider range of extremotolerant animal species.
“Our observations suggest that tardigrades can adjust their thermal conductance to protect themselves from heat,” explained Eswarappa. “As part of our next studies, we plan to identify the molecular mechanisms behind this phenomenon.”

Nvidia, Microsoft, and Arm are all teasing Nvidia’s new N1X laptop processors • The Verge
Tom Warren:
»
It’s the world’s worst kept secret that Nvidia is about to announce its own Arm-powered laptop chips at Computex this weekend, and now Microsoft, Nvidia, and Arm are all openly teasing the announcement. The Windows and Nvidia GeForce accounts on X both posted “A new era of PC” earlier today, and now Arm has followed up with an identical post.
All three posts include coordinates pointing to where Computex is hosted in Taipei. Nvidia is holding a Computex keynote in Taipei at 8PM PT / 11PM ET on Sunday night, where it’s rumored to be announcing its new N1 and N1x laptop chips.
These Arm-powered Nvidia processors have been long-rumored, with reports earlier this year suggesting that both Lenovo and Dell have been preparing new laptops with the N1X chips. We first heard rumors about Nvidia’s laptop processors in 2023, and Dell CEO Michael Dell hinted at the possibility of an AI PC with Nvidia during an interview in 2024.

An announcement too late for this collation, but maybe this time Microsoft will get Arm PCs to work. I’ve been seeing them launch them since 2011, when they first showed them off at CES.

Simon Calder’s 32 years on the road as travel correspondent for The Independent • The Independent
Simon Calder talks through his 32 years – now over – as The Independent’s “man who pays his way”:
»
1995: The Independent had a strict “no freebies” policy prescribed by founding editor Andreas Whittam Smith. So I was acutely aware of the cost of travel. The mid-Nineties saw some undoubted bargains – £179 for a Virgin Atlantic flight outbound from Heathrow to Los Angeles and back from New York JFK.
Yet within Europe, fares were stubbornly high. A questionably obtained student card eased the financial pain, but even so, London to Glasgow was a minimum of £100 return by air. Plenty of entrepreneurs had sought, unsuccessfully, to make flying affordable. So, when a fax arrived at the office of The Independent announcing a new carrier between Luton and Glasgow, beginning in November 1995, I paid it little heed.
The link between London and Scotland’s biggest city was conveniently carved up by Air UK, British Airways and British Midland. While easyJet promised fares as low as £29 each way, the business model seemed fatally flawed. You couldn’t buy through travel agents, only by phone – with the number emblazoned in orange on the plane.
There was no allocated seating – you grabbed a seat where you could. And the airline proposed charging passengers £1 for a cup of tea and a further 50p for a packet of shortbread, both of which were free on its frillier rivals. So, no thanks, I would not be going to Luton at 7am on 10 November to meet a 28-year-old shipping magnate named Stelios Haji-Ioannou.
Yet easyJet seems to have survived, along with what was, at the time, a small and struggling Irish airline named Ryanair.

Broadband and mobile bills are soaring in the UK – depending on who you ask • The Observer
Ben Zaranko:
»
if you believe the official data, the UK is a massive outlier. Between December 2016 and December 2025, across the euro area, the price of “wireless telephone services” fell by 20%, according to Eurostat. In the UK, ONS estimates suggest that prices increased by almost 40% over that period, before jumping again in April 2026 (something I’ll come back to). There’s a similarly dramatic divergence when looking at prices for “internet access provision services” (ie broadband) and for “bundled telecommunications services” (ie a combined broadband and TV package).
I say “if you believe the official data”, because this stuff is hard to measure. Often, the price listed online isn’t the one you’ll actually pay, if you ring up and haggle, or are willing to shop around. There’s also the thorny question of how to adjust for changes in the quality of service provided over time: if your bill stays the same, but your broadband speed doubles, has the price been cut in half?
Different countries take different approaches. A spokesperson for the ONS said that its approach “is consistent with best international practice and, in particular, our mobile phone charges methodology is considered to be the best approach to measuring price change to consumers”. Notably, Ofcom takes a different approach, and judges that the average price of average mobile use in the UK has barely changed since 2020. But it’s the ONS numbers that go into the official inflation figures.
There are two ways to interpret these trends – neither of them good. One possibility is that the UK really has seen mobile and broadband prices increase far more quickly than the rest of Europe. The other is that the ONS methodology struggles to capture things such as customer switching, discounts and improvements in quality and, as a result, could be overstating the “true” rate of inflation. A higher official measure of inflation would mean higher government spending on debt interest, a higher interest rate on student loans, and much else besides.
«
The feeling is definitely that prices just keep going up while you’re in a contract; in some ways it’s better to let the contract finish and move onto the rolling 30-day version, where prices tend to stay the same, which at least evades the annoyance of prices constant creeping upwards.

Microsoft starts canceling Claude Code licenses • The Verge
Tom Warren:
»
Microsoft first started opening up access to Claude Code in December, inviting thousands of its own developers to use Anthropic’s AI coding tool daily. It was part of an effort to get project managers, designers, and other employees to experiment with coding for the first time, and sources tell me that Claude Code has proved very popular inside Microsoft over the past six months. Perhaps a little too popular, as Microsoft is now preparing to walk back its Claude Code push.
I understand that Microsoft is planning to remove most of its Claude Code licenses and push many of its developers to use Copilot CLI instead. While Claude Code has been a popular addition, it has also undermined Microsoft’s new GitHub Copilot CLI coding tool — a command line version of GitHub Copilot that runs outside of development apps like Visual Studio Code.
I’m told that Microsoft’s Experiences + Devices team, which includes the engineers responsible for Windows, Microsoft 365, Outlook, Microsoft Teams, and Surface, is winding down its usage of Claude Code by the end of June. Sources tell me that engineers are being encouraged to start transitioning their workflows to GitHub Copilot CLI in the coming weeks, ahead of the cutoff.
Microsoft is telling employees that the decision is about converging on Copilot CLI as its main agentic command line interface tool across Experiences + Devices, but sources tell me the decision is also a financial one. The June 30th cutoff is the last day of Microsoft’s current financial year, and canceling Claude Code licenses is an easy way to cut some operating expenses for when the new financial year starts in July.

What is a dickover? • Daring Fireball
John Gruber on the scourge of the modern internet:
»
Here’s one from The Philadelphia Inquirer, for which I pay $20/month to subscribe, asking me to sign up for SMS text messages about the Jersey shore, while I’m logged into their cursed website, before they’ll let me see the article I came to read. Every time I see one of these I think about unsubscribing. I’m paying them to abuse my time and attention. I started capturing screenshots of every dickover I saw when I started working on this article, and I soon had to give up because I was collecting too many of them. But this one from Tom’s Hardware I actually enjoyed, because their own dickover got dicked over by one of their own fucking ads in a JavaScript Z-axis slapfight.
If you visit a website you should … see the website. See its content. Be able to read the article whose page you are attempting to visit. Showing a “subscribe to our newsletter” or “accept our fucking cookies” dickover to someone trying to read an article on the web makes no more sense than sending out an email newsletter that only contains a link to read the newsletter on a webpage. A webpage should show the webpage. An email should show the email. I should not have to explain this.
Some sites hit you with their dickovers on page load, when you might be braced for it. We’re all braced for obstacles and annoyances these days when we load web pages. But some sneaky, cowardly bastards sucker-punch you with their dickbars only after you have started reading, and begin to scroll down the page. Then, wham, they hit with their dickover. It’s a goddamn privilege for anyone to bestow your article, story, or product page with their attention. The gall, to deliberately interrupt them while they are in the middle of actively reading, to present them with a dickover.

The fabulous irony is that the principal annoyance a few years back was popunders, which secreted themselves under the window you were looking at and only appeared when you had closed it. Does anyone remember the X10 webcam? (Thanks Joe S for the link.)
