NASA used specialized Schlieren photography to capture an image of Boom Supersonic's XB-1 demonstrator aircraft breaking the sound barrier on February 10, 2025 and producing shock waves as it exceeded Mach 1. The flight produced no audible sonic boom, marking progress toward the goal of quiet supersonic travel. CNN reports: "This image makes the invisible visible," said Blake Scholl, founder and CEO of Boom Supersonic, in a press release. In order to capture the Schlieren images, Boom chief test pilot Tristan "Geppetto" Brandenburg positioned XB-1 at an exact time in a precise location over the Mojave Desert. As the aircraft flew in front of the sun, NASA's team documented the changing air speeds as speeds over Mach 1, the speed of sound (761.23 miles per hour or 1,225.1 kilometers per hour). The images were captured during ground telescopes with special filters that detect air distortions. You can view the photo here.

Google Play on Android devices is being updated to include a new search filter for widgets, widget badges on app detail pages, and a curated editorial page dedicated to widgets. The Verge reports: With the search filter, users will be able to more easily search for apps with widgets. The badge "eliminates guesswork for users and highlights your widget offerings, encouraging them to explore and utilize this capability," Taiwo-Peters says. And the curated editorial page will show off "collections of excellent widgets." The updated widget discoverability tools will be "coming soon," Taiwo-Peters says. "Historically, one of the challenges with investing in widget development has been discoverability and user understanding," product manager Yinka Taiwo-Peters says in the post. "You've asked for better ways for users to find and utilize your widgets, and we're delivering." Yinka Taiwo-Peters also acknowledges that "we understand that the effort required to build and maintain widgets needs to be justified by user adoption."

An anonymous reader quotes a report from TechCrunch: The United States has suspended its offensive cyber operations against Russia, according to reports, amid efforts by the Trump administration to grant Moscow concessions to end the war in Ukraine. The reported order to halt U.S.-launched hacking operations against Russia was authorized by U.S. Defense Secretary Pete Hegseth, according to The Record. The new guidance affects operations carried out by U.S. Cyber Command, a division of the Department of Defense focused on hacking and operations in cyberspace, but does not apply to espionage operations conducted by the National Security Agency. The reported order has since been confirmed by The New York Times and The Washington Post. The order was handed down before Friday's Oval Office meeting between U.S. President Donald Trump, Vice President JD Vance, and Ukrainian President Volodymyr Zelenskyy, according to the reports. The New York Times said that the instruction came as part of a broader effort to draw Russian President Vladimir Putin into talks about the country's ongoing war in Ukraine. The Guardian also reports that the Trump administration has signaled it no longer views Russian hackers as a cybersecurity threat, and reportedly ordered U.S. cybersecurity agency CISA to no longer report on Russian threats. The newspaper cites a recent memo that set out new priorities for CISA, including threats faced by China and protecting local systems, but the memo did not mention Russia. CISA employees were reportedly informed verbally that they were to pause any work on Russian cyber threats.

A fully driverless Maserati MC20 Coupe set a new autonomous land speed record, reaching 197.7 mph at the Kennedy Space Center. The Verge reports: The Maserati was running self-driving software developed by Politecnico di Milano, Italy's largest scientific and technological university. The team also worked with the Indy Autonomous Challenge, which most recently ran at the Las Vegas Motor Speedway during CES 2025. In the shadow of NASA's iconic Space Shuttles, the race car flew down the 2.8-mile runway at record-breaking speeds, surpassing the 192.2mph record that was also held by Indy Autonomous Challenge and PoliMOVE, set by an IAC AV-21 race car in April 2022. The Maserati MC20 is a stylish -- and expensive -- choice for the autonomous run. Retailing for at least $239,000, the race car sports a mid-mounted, twin-turbocharged 3.0-liter V-6 that Maserati calls the Nettuno. The engine makes serious power: 621 horsepower and 538 pound-feet of torque, which is sent through an eight-speed dual-clutch automatic transmission to the rear wheels.

Microsoft has introduced Dragon Copilot, a voice-activated AI assistant for doctors that integrates dictation and ambient listening tools to automate clinical documentation, including notes, referrals, and post-visit summaries. The tool is set to launch in May in the U.S. and Canada. CNBC reports: Microsoft acquired Nuance Communications, the company behind Dragon Medical One and DAX Copilot, for about $16 billion in 2021. As a result, Microsoft has become a major player in the fiercely competitive AI scribing market, which has exploded in popularity as health systems have been looking for tools to help address burnout. AI scribes like DAX Copilot allow doctors to draft clinical notes in real time as they consensually record their visits with patients. DAX Copilot has been used in more than 3 million patient visits across 600 health-care organizations in the last month, Microsoft said. Dragon Copilot is accessible through a mobile app, browser or desktop, and it integrates directly with several different electronic health records, the company said. Clinicians will still be able to draft clinical notes with the assistant like they could with DAX Copilot, but they'll be able to use natural language to edit their documentation and prompt it further, Kenn Harper, general manager of Dragon products at Microsoft, told reporters on the call. For instance, a doctor could ask questions like, "Was the patient experiencing ear pain?" or "Can you add the ICD-10 codes to the assessment and plan?" Physicians can also ask broader treatment-related queries such as, "Should this patient be screened for lung cancer?" and get an answer with links to resources like the Centers for Disease Control and Prevention.

An anonymous reader quotes a report from TechCrunch: Chipmaker TSMC said that it aims to invest "at least" $100 billion in chip manufacturing plants in the U.S. over the next four years as part of an effort to expand the company's network of semiconductor factories. President Donald Trump announced the news during a press conference Monday. TSMC's cash infusion will fund the construction of several new facilities in Arizona, C. C. Wei, chairman and CEO of TSMC, said during the briefing. "We are going to produce many AI chips to support AI progress," Wei said. TSMC previously pledged to pour $65 billion into U.S.-based fabrication plants and has received up to $6.6 billion in grants from the CHIPS Act, a major Biden administration-era law that sought to boost domestic semiconductor production. The new investment brings TSMC's total investments in the U.S. chip industry to around $165 billion, Trump said in prepared remarks. [...] TSMC, the world's largest contract chip maker, already has several facilities in the U.S., including a factory in Arizona that began mass production late last year. But the company currently reserves its most sophisticated facilities for its home country of Taiwan.

Former Intel CEO Craig Barrett urged the rehiring of Pat Gelsinger, who was abruptly fired two months ago, arguing he should "finish the job he has aptly handled over the past few years." "Pat Gelsinger did a great job resuscitating the technology development team," Barrett wrote, criticizing the company's current leadership under "a CFO and a product manager." He suggested firing the Intel board rather than splitting the company. Barrett's comments come in response to proposals from four former board members advocating for Intel's separation into design and manufacturing businesses. Barrett dismissed these board members as "two academics and two former government bureaucrats" lacking semiconductor industry expertise. The former CEO praised Intel's technological resurgence under Gelsinger, noting its capabilities now match industry leader TSMC's 2nm technology, with additional advances in imaging technology and backside power delivery to complex chips. "Intel is backâ"from a technology point of view," Barrett wrote, arguing the best path forward is building on current momentum rather than organizational restructuring that would disrupt the company's 100,000-plus employees across multiple continents.

The world's biggest call center company is using artificial intelligence to "neutralise" Indian accents for Western customers. From a report: Teleperformance said it was applying real-time AI software on phone calls in order to increase "human empathy" between two people on the phone. The French company's customers in the UK include parts of the Government, the NHS, Vodafone and eBay. Teleperformance has 90,000 employees in India and tens of thousands more in other countries. It is using software from Sanas, an American company that says the system helps "build a more understanding world" and reduces miscommunication. The company's website says it makes call center workers more productive and means customer service calls are resolved more quickly. The company also says it means call center workers are less likely to be abused and customers are less likely to demand to speak to a supervisor. It is already used by companies including Walmart and UPS.

Silicon Valley, the place that did more than any other to pioneer artificial intelligence, is the most exposed to its ability to automate work. That's according to an analysis by researchers at the Brookings Institution, a think tank, which matched the tasks that OpenAI's ChatGPT-4 could do with the jobs that are most common in different US cities. From a report: The result is a sharp departure from previous rounds of automation. Whereas technologies like robotics came for middle-class jobs -- and manufacturing cities such as Detroit -- generative AI is best at the white-collar work that's highly paid and most common in "superstar" cities like San Francisco and Washington, DC. The Brookings analysis is of the US, but the same logic would apply anywhere: The more a city's economy is oriented around white-collar knowledge work, the more exposed it is to AI. "Exposure" doesn't necessarily mean automation, stressed Mark Muro, a senior fellow at Brookings and one of the study's authors. It could also mean productivity gains. From the Brookings report: Now, the higher-end workers and regions only mildly exposed to earlier forms of automation look to be most involved (for better or worse) with generative AI and its facility for cognitive, office-type tasks. In that vein, workers in high-skill metro areas such as San Jose, Calif.; San Francisco; Durham, N.C.; New York; and Washington D.C. appear likely to experience heavy involvement with generative AI, while those in less office-oriented metro areas such as Las Vegas; Toledo, Ohio; and Fort Wayne, Ind. appear far less susceptible. For instance, while 43% of workers in San Jose could see generative AI shift half or more of their work tasks, that share is only 31% of workers in Las Vegas.

Britain, the birthplace of the Industrial Revolution, now suffers from its opposite: profound energy shortages and deep affordability crises [non-paywalled link]. A new report titled "Foundations" identifies the root cause -- "it is difficult to build almost anything, anywhere" in the UK. Housing exemplifies this malaise. Since the 1990s, homeownership among young British workers has halved while housing prices doubled. The 1947 Town and Country Planning Act effectively nationalized development rights, requiring special permission for new construction and establishing restrictive "green belts." Despite Margaret Thatcher's market reforms, British house-building never recovered. This constrictive policy has stymied potential growth beyond housing, Atlantic reports. Cambridge remains a small city despite biotech breakthroughs that might have transformed it into a major hub. Transit infrastructure languishes -- Leeds is Europe's largest city without a metro system. Energy production has collapsed, with per capita electricity generation now roughly one-third of America's. Britain faces a self-imposed scarcity crisis. Environmental regulations, while beneficial, created a one-way system where lawsuits easily block development. As co-author Sam Bowman summarized: "Europe has an energy problem; the Anglosphere has a housing problem; Britain has both." The solution requires comprehensive reform-- overhauling the planning system, reducing anti-growth litigation, and encouraging energy production to unlock what the private sector "already wants to do."

U.S. publishers are increasingly abandoning paperback editions of nonfiction books, eliminating a traditional second chance for authors to reach readers with lower-priced versions of their work. New adult nonfiction paperback titles plummeted 42% between 2019 and 2024 [non-paywalled source] to under 40,000, while hardcover titles fell just 9% during the same period, according to Bowker Books in Print. "It's profoundly demoralizing that a book that might have taken four years to write and was published with such promise is done after five months," Dan Conaway, a senior literary agent with Writers House, told WSJ. The shift reflects changing consumer habits, the rise of digital formats, and market realities where Amazon sometimes prices hardcovers below paperbacks. Barnes & Noble now promotes just one nonfiction paperback monthly.

Job placement rates have declined at all top U.S. business schools [non-paywalled source] since 2021, leaving MBA graduates anxious about their expensive degrees' return on investment. Harvard Business School, which produced Wall Street titans like Bill Ackman and Ray Dalio, saw the percentage of graduates without job offers three months post-graduation rise from 4% in 2021 to 15% currently. Similar trends are evident at Stanford, Chicago Booth, MIT Sloan, and Wharton, where 7% of 2024 graduates lacked offers within three months of completing their programs. Industry experts cited in a Bloomberg report attribute the downturn to tepid white-collar job growth, declining private-sector wages, and high-profile layoffs at companies including Meta and JPMorgan.

Nvidia and Broadcom are conducting manufacturing tests using Intel's advanced 18A chip production process, according to Reuters, signaling potential confidence in the struggling chipmaker's contract manufacturing ambitions. The previously unreported tests could lead to significant manufacturing contracts for Intel, whose foundry business has suffered delays and lacks major chip designer customers. AMD is also evaluating Intel's 18A technology, which competes with Taiwan's dominant TSMC, according to the report. The current tests focus on determining capabilities of Intel's process rather than running complete chip designs. Intel faces additional setbacks, with qualification of critical intellectual property for 18A taking longer than expected, potentially delaying some customer chip production until mid-2026.

Speaking of some concept devices that Lenovo has unveiled, the company today teased its ThinkBook "codename Flip" AI PC Concept at Mobile World Congress, featuring a flexible 18.1-inch OLED display that can transform between three configurations: a traditional 13.1-inch clamshell, a folded 12.9-inch tablet, or a laptop with an extra-tall vertical screen. Unlike the motorized ThinkBook Plus Gen 6 expected in June, the Flip uses the display's flexibility to fold behind itself, eliminating motors while gaining 0.4 inches of additional screen space. Users can mirror content on the rear-facing portion when folded or enjoy the full 2000x2664 resolution display in vertical orientation. The concept also features a SmartForcePad trackpad with LED-illuminated shortcut layers. While still in prototype phase, Lenovo has specs in mind: Intel Ultra 7 processor, 32GB RAM, PCIe SSD storage, and Thunderbolt 4 connectivity.

Daniel Parris: Some TV shows take a while to "get good." Modern classics like Breaking Bad, The Wire, Community, and Bojack Horseman are notorious for "starting slow" and are often recommended with a disclaimer like "Give it a few episodes; I promise it gets good!" At the same time, some shows never get good. Recently, I started a spy series called The Agency, which could best be characterized as premium mediocre (at least so far). There are big-name actors (Michael Fassbender, Jeffrey Wright, Richard Gere), expensive sets, and glossy camerawork -- but after a few installments, I'm trapped in a liminal space between engaged and listless. At the end of each episode, I'm left with the same thought: "Maybe the next one will get good." Committing to a mediocre program or continuing with a floundering series elicits a state of (mildly) torturous ambiguity. Should you cut your losses, or is this show some late-blooming classic like Breaking Bad? What is the optimal number of episodes one should watch before cleansing a subpar series from their life? Surely, a universal number must exist! Like 42, but for television. So today, we'll explore how long it takes a new show to reach its full potential and how many lackluster episodes you should grant an established series before cutting ties. His analysis reveals that viewers should watch six episodes before quitting TV shows. The study, based on IMDb user ratings, found most series require six to seven episodes before early ratings match or exceed the show's long-term average. After six consecutive subpar episodes, the likelihood of permanent decline exceeds 50%, making it the optimal point to abandon disappointing series. Several acclaimed shows including Breaking Bad, Friends, and Seinfeld required multiple episodes before reaching their quality potential, with Seinfeld needing 16 episodes to match its series average. The research also identified a pattern where long-running shows typically experience quality decline around seasons five and six, with ratings dropping below first-season averages and continuing to fall.

China aims to commercialize nuclear fusion technology for use in emissions-free power generation by 2050, according to the countryâ(TM)s state-owned atomic company. From a report: China National Nuclear Corp., which runs an experimental device dubbed the 'artificial sun,' could start commercial operation of its first power generation project about five years after a demonstration phase starting around 2045, it said in a media briefing on Friday. The Asian nation has recently stepped up its ambitions in achieving nuclear fusion, a process by which the sun and other stars generate energy and that is considered a near-infinite form of clean energy. It is notoriously difficult to carry out in a sustained and usable manner and only a handful of countries like the US, Russia and South Korea have managed to crack the basics.

Apple users noticed a change in 2023, "when streaming platforms like Netflix, HBO Max, Amazon Prime, and the Criterion Channel imposed a quiet embargo on the screenshot," noted the film blog Screen Slate: At first, there were workarounds: users could continue to screenshot by using the browser Brave or by downloading extensions or third-party tools like Fireshot. But gradually, the digital-rights-management tech adapted and became more sophisticated. Today, it is nearly impossible to take a screenshot from the most popular streaming services, at least not on a Macintosh computer. The shift occurred without remark or notice to subscribers, and there's no clear explanation as to why or what spurred the change... For PC users, this story takes a different, and happier, turn. With the use of Snipping Tool — a utility exclusive to Microsoft Windows, users are free to screen grab content from all streaming platforms. This seems like a pointed oversight, a choice on the part of streamers to exclude Mac users (though they make up a tiny fraction of the market) because of their assumed cultural class. "I'm not entirely sure what the technical answer to this is," tech blogger John Gruber wrote this weekend, "but on MacOS, it seemingly involves the GPU and video decoding hardware..." These DRM blackouts on Apple devices (you can't capture screenshots from DRM video on iPhones or iPads either) are enabled through the deep integration between the OS and the hardware, thus enabling the blackouts to be imposed at the hardware level. And I don't think the streaming services opt into this screenshot prohibition other than by "protecting" their video with DRM in the first place. If a video is DRM-protected, you can't screenshot it; if it's not, you can. On the Mac, it used to be the case that DRM video was blacked-out from screen capture in Safari, but not in Chrome (or the dozens of various Chromium-derived browsers). But at some point a few years back, you stopped being able to capture screenshots from DRM videos in Chrome, too -- by default. But in Chrome's Settings page, under System, if you disable "Use graphics acceleration when available" and relaunch Chrome, boom, you can screenshot everything in a Chrome window, including DRM video... What I don't understand is why Apple bothered supporting this in the first place for hardware-accelerated video (which is all video on iOS platforms -- there is no workaround like using Chrome with hardware acceleration disabled on iPhone or iPad). No one is going to create bootleg copies of DRM-protected video one screenshotted still frame at a time -- and even if they tried, they'd be capturing only the images, not the sound. And it's not like this "feature" in MacOS and iOS has put an end to bootlegging DRM-protected video content. Gruber's conclusion? "This 'feature' accomplishes nothing of value for anyone, including the streaming services, but imposes a massive (and for most people, confusing and frustrating) hindrance on honest people simply trying to easily capture high-quality (as opposed to, say, using their damn phone to take a photograph of their reflective laptop display) screenshots of the shows and movies they're watching."

"TrapC, a fork of the C language, is being developed as a potential solution for memory safety issues that have hindered the C and C++ languages," reports InfoWorld. But also being developed is a compiler named trapc "intended to be implemented as a cybersecurity compiler for C and C++ code, said developer Robin Rowe..." Due by the end of this year, trapc will be a free, open source compiler similar to Clang... Rowe said. TrapC has pointers that are memory-safe, addressing the memory safety issue with the two languages. With TrapC, developers write in C or C++ and compile in TrapC, for memory safety... Rowe presented TrapC at an ISO C meeting this week. Developers can download a TrapC whitepaper and offer Rowe feedback. According to the whitepaper, TrapC's memory management is automatic and cannot leak memory. Pointers are lifetime-managed, not garbage-collected. Also, TrapC reuses a few code safety features from C++, notably member functions, constructors, destructors, and the new keyword. "TrapC Memory Safe Pointers will not buffer overrun and will not segfault," Rowe told the ISO C Committee standards body meeting, according to the Register. "When C code is compiled using a TrapC compiler, all pointers become Memory Safe Pointers and are checked." In short, TrapC "is a programming language forked from C, with changes to make it LangSec and Memory Safe," according to that white paper. "To accomplish that, TrapC seeks to eliminate all Undefined Behavior in the C programming language..." "The startup TRASEC and the non-profit Fountain Abode have a TrapC compiler in development, called trapc," the whitepaper adds, and their mission is "to enable recompiling legacy C code into executables that are safe by design and secure by default, without needing much code refactoring... The TRASEC trapc cybersecurity compiler with AI code reasoning is expected to release as free open source software sometime in 2025." In November the Register offered some background on the origins of TrapC...

There are things which are true. Regular expressions frequently perform badly. They're hard to read. Email addresses are not actually regular languages, and thus can't truly be validated (in all they're many possible forms) by a pure regex.

These are true. It's also true that a simple regex can get you most of the way there.

Lucas found this in their codebase, for validating emails.

function echeck(str) { var at="@"; var dot="."; var lat=str.indexOf(at); var lstr=str.length; var ldot=str.indexOf(dot); if (str.indexOf(at)==-1){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(at)==-1 || str.indexOf(at)==0 || str.indexOf(at)==lstr){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(dot)==-1 || str.indexOf(dot)==0 || str.indexOf(dot)==lstr){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(at,(lat+1))!=-1){ alert("You must include an accurate email address for a response."); return false; } if (str.substring(lat-1,lat)==dot || str.substring(lat+1,lat+2)==dot){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(dot,(lat+2))==-1){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(" ")!=-1){ alert("You must include an accurate email address for a response."); return false; } return true; }

It checks that the string contains an "@", and the "@" is not at the beginning or end of the string. Then it does the same check for a ".". Then it checks that there isn't a second "@". Then it checks that there are at least two non-"@" characters before the ".". Then it checks that there's at least one "." after the "@". Then it checks that there are no spaces.

Like a regex, I don't think this covers the entire space of valid and invalid email addresses, but that's just because the email address spec is complicated. It likely qualifies as "good enough", on that front. But it's the most awkward way to express that series of tests, especially since they create variables which might be useful, but never use them, thus calling str.indexOf many, many times. The awkwardness becomes more obvious with the way it outputs the same error message in multiple branches. Outputs them using alert I might add, which is the kind of choice that should send someone to the Special Hell™.

It's a feature-length film "rendered on a free and open-source software platform called Blender," reports Reuters. And it just won the Oscar for best animated feature film, beating movies from major studios like Disney/Pixar and Dreamworks. In January Blender.org called Flow "the manifestation of Blender's mission, where a small, independent team with a limited budget is able to create a story that moves audiences worldwide, and achieve recognition with over 60 awards, including a Golden Globe for Best Animation and two Oscar nominations." The entire project cost just $3.7 million, reports NPR — though writer/director Gints Zilbalodis tells Blender.org that it took about five and a half years. "I think a certain level of naivety is necessary when starting a project," Zilbalodis tells Blender. "If I had known how difficult it would be, I might never have started. But because I didn't fully grasp the challenges ahead, I just dove in and figured things out along the way..." Zilbalodis: [A]fter making a few shorts, I realized that I'm not good at drawing, and I switched to 3D because I could model things, and move the camera... After finishing my first feature Away, I decided to switch to Blender [from Maya] in 2019, mainly because of EEVEE... It took a while to learn some of the stuff, but it was actually pretty straightforward. Many of the animators in Flow took less than a week to switch to Blender... I've never worked in a big studio, so I don't really know exactly how they operate. But I think that if you're working on a smaller indie-scale project, you shouldn't try to copy what big studios do. Instead, you should develop a workflow that best suits you and your smaller team. You can get a glimpse of their animation style in Flow's official trailer. NPR says that ultimately Flow's images "possess a kinetic elegance. They have the alluring immersiveness of a video game..."
