A short introduction to optimal transport and Wasserstein distance (2020)

A Short Introduction to Optimal Transport and Wasserstein Distance These notes provide a brief introduction to optimal transport theory, prioritizing intuition over mathematical rigor. A more rigorous presentation would require some additional background in measure theory. Other good introductory resources for optimal transport theory include: Why Optimal Transport Theory? A fundamental problem in statistics and machine learning is to come up with useful measures of “distance” between pairs o

‘Star Trek’ Journalists, Ranked

The potential for what journalism looks like in Star Trek is a heady idea that’s been around as long as the series itself. What does reporting the news look like in utopia? What does it mean that the Federation has its own news networks, alongside a host of interstellar media organizations? What does freedom of information mean in a universe that has Starfleet? And yet, we’ve actually had very few characters appear in the series as fully dedicated journalists and reporters. That changed a littl

Google Did Not Unilaterally Decide to Kill XSLT

It’s uncommon, but not unheard of, for a GitHub issue to spark an uproar. That happened over the past month or so as the WHATWG (Web Hypertext Application Technology Working Group, which I still say should have called themselves a Task Force instead) issue “Should we remove XSLT from the web platform?” was opened, debated, and eventually locked once the comment thread started spiraling into personal attacks. Other discussions have since opened, such as a counterproposal to update XSLT in the web

Got a scary T-Mobile text about your account? Here’s what it really means

Joe Maring / Android Authority TL;DR T-Mobile sent a text about “Authorized Users” that some customers mistook as a fraud warning. It was confirmed to be a mass informational campaign, not an unauthorized purchase attempt. It’s not the first eyebrow-raising SMS from the carrier this month. If you’re on T-Mobile, you might be starting to get a bit concerned about the carrier’s comms strategy. Following a security-related text from the carrier earlier this month that looked scammy but was real

The warning signs the AI bubble is about to burst

“When will the internet bubble burst?” the cover story of Barron’s asked on March 20 2000. “That unpleasant popping sound is likely to be heard before the end of this year.” In fact, that same day, one of the most high-profile tech businesses of the moment suffered a share price plunge of 60pc. A flood of other collapses followed, evaporating trillions of dollars. Now, some on Wall Street fear that “unpleasant popping sound” may be imminent for the artificial intelligence (AI) boom.

Some Pixel owners are getting a more powerful At A Glance widget

Joe Maring / Android Authority TL;DR Some Pixel phone owners are seeing sports and finance cards in their At A Glance widget. The sports card shows soccer scores, but our previous leak also revealed support for cricket scores. The finance card seems to show stock information. Google’s At A Glance widget is a useful feature on Pixel phones. It displays the weather, calendar events, boarding passes, and more directly on your home screen.

Tesla Takes So Long to Report Crash Data, Even Trump’s Regulators Are Taking Notice

It turns out it’s actually possible for a corporation to drag its feet for so long that even the Trump administration takes issue with it. The National Highway Traffic Safety Administration announced that it will investigate Tesla’s habit of taking months to submit accident reports that involve the company’s driver-assistance technology, according to a report from Reuters. Just how late is Tesla getting its crash report information to the NHTSA? The agency asks that companies submit reports wit

Tesla faces U.S. auto safety probe over faulty crash reporting

Elon Musk, CEO of SpaceX and Tesla, attends the Viva Technology conference at the Porte de Versailles exhibition center in Paris on June 16, 2023. Elon Musk's Tesla is facing a federal probe by the National Highway Traffic Safety Administration after the U.S. auto safety agency found that the company was not reporting crashes as required.

China’s Great Firewall Mysteriously Severed Connection to the World for an Hour

For about an hour on Wednesday, China appeared to go dark—or at least internet access across the country did. According to an analysis published by the Great Firewall Report, a group that monitors internet censorship efforts in China, something happened in the wee hours of Wednesday morning that resulted in China blocking almost all traffic to TCP port 443, the standard port for HTTPS traffic. Between the hours of 12:34 and 1:48 AM in Beijing, someone was observed “unconditionally injecting for

95% of Companies See 'Zero Return' on $30B Generative AI Spend

Over the last three years, companies worldwide have invested between 30 and 40 billion dollars into generative artificial intelligence projects. Yet most of these efforts have brought no real business return. A new study from MIT found that 95 percent of enterprise organizations report zero measurable gains from the adoption of AI tools. Only a small group has seen strong benefits. “Just five percent of integrated AI pilots are extracting millions in value,” the report said. In contrast, the v

AI crawlers, fetchers are blowing up websites; Meta, OpenAI are worst offenders

Cloud services giant Fastly has released a report claiming AI crawlers are putting a heavy load on the open web, slurping up sites at a rate that accounts for 80 percent of all AI bot traffic, with the remaining 20 percent used by AI fetchers. Bots and fetchers can hit websites hard, demanding data from a single site in thousands of requests per minute.

The AI Report That’s Spooking Wall Street

A new report from MIT is casting doubt on the hype around the financial value AI brings to businesses, and may be triggering a small tech stock sell-off on Tuesday. The report, The GenAI Divide: State of AI in Business 2025, found that the promised AI gold rush isn’t paying off for most companies yet. Despite the major push to adopt AI tools in the corporate world, fewer than one in ten AI pilot programs have generated real revenue gains. The rest are having no impact on a company’s bottom lin
