Elon Musk Hires Immigrants So He Can Pay Them Less, Lawsuit Allege

Tesla, which has come under repeated fire due to CEO Elon Musk's political antics and its quality control issues, has been now slapped with a lawsuit that alleges that the company prefers hiring visa holding immigrants over American citizens in order to save money, according to Reuters. The lawsuit claims that Tesla relies heavily on workers who hold the H-1B visa, which grants temporary employment for specialized technical jobs, and that workers who have been recently laid off from the electri

The 9 Best Grills of 2025

Frequently Asked Questions What Should You Look for in a Grill? AccordionItemContainerButton LargeChevron Take a trip to your local big-box home improvement store and you'll see dozens of grill models not mentioned here. Are they any good? Most of them are probably fine, but we suggest sticking with brands you recognize. The nice thing about shopping in person is you can get a better sense of the grill's sturdiness. Give it a good shake, and make sure it seems well put together. If it's a brand

Court lets NSF keep swinging axe at $1B in research grants

A US court has cleared the way for the National Science Foundation to press ahead with the cancellation of more than 1,700 research grants worth upwards of $1 billion. The ruling, handed down this week by Judge Jia Cobb of the DC District Court, rejects a request from researchers, universities and scientific societies to reinstate the cancelled grants while the case is heard. The plaintiffs had argued that NSF's mass terminations were arbitrary, unlawful and would do irreparable harm to the cou

Octopus Energy spins off its Kraken utility billing and AI platform

British renewable energy provider Octopus Energy said this week that it’s spinning off Kraken, its tech platform for utilities, spurred in part by $500 million in committed annual revenue from other utilities and energy providers. An eventual Kraken IPO could be valued at $15 billion and could occur within a year, according to The Wall Street Journal. Kraken was actually the company’s initial product, according to Octopus CEO Greg Jackson. “We created Octopus as the ‘demo client,’” he told the

Don’t Get Too Excited for That Nvidia and Intel Chip Just Yet

What’s the point of competition anymore? Nvidia may still be trying to make its own CPUs. Intel could have beefed up its Arc GPUs around the corner. But now the two U.S.-based chipmakers plan to make SoCs, or system-on-chips, combining each company’s specialty. While we’re all curious about what this means for the future of PCs, you’ll need to wait a good long while to see what form the new chips from the new Wonder Twins will take. Nvidia is effectively netting a $5 billion stake in Intel, a d

Amazon Prime Is Ending Shared Free Shipping. What to Know and When It Happens

If you've been using someone else's Amazon Prime membership for free shipping, but you don't live in the same house, you may need to pay another subscription fee soon. According to Amazon's updated customer service page, the online retail giant is ending its Prime Invitee benefit-sharing program Oct. 1.

How Energy-Generating Sidewalks Work

We walk here, we walk there, we walk everywhere. Maybe you’re headed to work or to lunch in a busy city. You’re expending energy, and the exercise is good for you. But what if, on top of that, we could recapture all that freely supplied energy and convert it to usable electricity? This is a real thing. Systems have been installed in dozens of countries. Check out this video. And why stop there? You could put them in discotheques and harness that fancy footwork to power the strobe lights. Or bui

Leatherman (vagabond)

American vagabond of unknown and disputed identity The Leatherman ( c. 1839–1889) was a vagabond famous for his handmade leather suit of clothes who traveled through the northeastern United States on a regular circuit between the Connecticut River and the Hudson River from roughly 1857 to 1889. Of unknown origin, he was thought to be French-Canadian because of his fluency in the French language, his "broken English", and the French-language prayer book found on his person after his death. His i

Intel says Arc GPUs will live on after Nvidia deal

In the future, Intel will make CPUs with Nvidia graphics inside — among other things , Nvidia CEO Jensen Huang confirmed today that Nvidia will contribute “GPU chiplets” that Intel can place alongside its x86 CPU cores instead of the Arc integrated graphics it develops in-house today. But, at least for now, Intel says that doesn’t mean Intel’s own graphics are going away. “We’re not discussing specific roadmaps at this time, but the collaboration is complementary to Intel’s roadmap and Intel wi

Nvidia buys $5B stake in Intel, planning AI chip collaboration

Nvidia has agreed to buy a $5 billion stake in Intel as part of a broader deal to together develop “multiple generations” of data center and PC products. Nvidia will acquire the Intel stock for $23.28 per share, a slight discount on the company’s previous trading price. According to Reuters, the deal would make Nvidia one of Intel’s largest shareholders, owning about 4% of the company. Intel shares were up as much as 30% in early trading on Thursday morning. The companies will integrate their

PostgreSQL Maintenance Without Superuser

How many people/services have superuser access to your PostgreSQL cluster(s)? Did you ever ask why your software engineers might need it? Or your BI team? Why those use cases require same privileges as someone who can drop your databases? The answer isn't because these operations are inherently dangerous - it's because PostgreSQL historically offered limited options for operational access or simply because not enough people are aware of the options. So the common practice is to either got basic

Software update shoves ads onto Samsung’s pricey fridges

Days after someone revealed the news on social media, Samsung confirmed today that it is showing advertisements on some US customers’ smart fridges. Samsung said the ads showing on some Family Hub-series fridges are part of a pilot program, but we suspect that they may become more permanent additions to Samsung fridges and/or other types of screen-equipped smart home appliances. In a statement sent to Ars Technica, Samsung confirmed that it is “conducting a pilot program to offer promotions and

Microsoft’s AI Copilot Invades Congress

The House will soon begin using M365 Copilot as part of a broader effort to integrate AI “into its daily operations,” Axios says. Speaker of the House Mike Johnson is expected to announce th

How to Debug Chez Scheme Programs (2002)

How to Debug Chez Scheme Programs R. Kent Dybvig August 2002 When a program fails to operate as it should, it is said to have a bug. A bug is the root cause of an observed behavior, such as failure to terminate, failure to perform some action, termination with an error message, or merely producing incorrect results. The process of debugging a program is one of finding all of the bugs and "exterminating" them. This process first requires feeding the program a representative set of test cases,

Meta launches Hyperscape, technology to turn real-world spaces into VR

Although today’s Meta Connect developer conference was largely about new smart glasses, the social networking company did announce a handful of metaverse updates during Wednesday’s keynote.

The company announced that Hyperscape Capture is now rolling out in Early Access, meaning Quest device owners will b

The DOGE Subcommittee Hearing on Weather Modification Was a Nest of Conspiracy Theorizing

“What this whole debate comes down to is who controls the skies,” Republican representative Marjorie Taylor Greene of Georgia told the audience at a House Oversight Committee hearing on Tuesday. “Do we believe in God and that he has dominion over his perfect creation of planet Earth? Do we believe that he has given us everything we need to survive as a civilization since the beginning of time? Or do you believe in man’s claim of authority over the weather, based on scientists that have only been
