It has a lot of features that increase different aspects of the CPU performance to new levels, never seen before.Most importantly, the instruction fetch rate is increased from 16 to 32 bytes per clock cycle. The 16-bytes fetch rate has been a serious bottleneck in both Intel and AMD processors through ma

Microsoft to stop using China-based teams to support Department of Defense

Last week, Microsoft announced that it would no longer use China-based engineering teams to support the Defense Department’s cloud computing systems, following ProPublica’s investigation of the practice, which cybersecurity experts said could expose the government to hacking and espionage. But it turns out the Pentagon was not the only part of the government facing such a threat. For years, Microsoft has also used its global workforce, including China-based personnel, to maintain the cloud syst

Razer Pro Click V2 Vertical Review: A Hybrid Gaming Mouse

wired.com Henri Robbins 2025-12-29 20:00:00

Switching to a vertical mouse is a hard sell. Having to change how you use a mouse completely can be an intimidating task, especially with how unnatural the new hand position feels at first—you’re going entirely against the muscle memory you’ve spent years building up. One of the largest challenges to the switch is the initial loss of pointer accuracy. If you’re in an office setting, you may find yourself wandering around a bit or struggling to move your new mouse as quickly as you did before.

What is X-Forwarded-For and when can you trust it? (2024)

news.ycombinator.com Unknown 2025-12-26 08:18:06

The X-Forwarded-For (XFF) HTTP header provides crucial insight into the origin of web requests. The header works as a mechanism for conveying the original source IP addresses of clients, and not just across one hop, but through chains of multiple intermediaries. This list of IPv4 and IPv6 addresses is helpful to understand where requests have really come from in scenarios where they traverse several servers, proxies, or load balancers.

A Creepy Corn Maze Awaits at the ‘Clown in a Cornfield’ Activation

Clown in a Cornfield is a million-dollar title—so eerie, so evocative, and so perfectly descriptive of Eli Craig‘s horror movie, which hit theaters earlier this year. It’s headed to Shudder and AMC+ August 8, but even if you’ve been waiting to catch it on streaming, there’s much to scream about with its San Diego Comic-Con immersive experience. Why?

Tesla wants to bring robotaxis to San Francisco. Here’s what’s standing in the way.

Tesla is launching an even-more-limited version of its early robotaxi service in San Francisco this weekend, according to Business Insider, after an initial rollout began last month in Austin, Texas. The company plans to send invites to Tesla owners to test the service, according to the report. Depending on how and if Tesla proceeds, its actions could violate state regulations — and even if there’s a human safety driver sitting behind the wheel while its vehicles operate autonomously.

Tesla Readies a Taxi Service in San Francisco—but Not With Robotaxis

wired.com Aarian Marshall 2025-12-30 12:26:14

Tesla has publicly staked its future on its robotaxis. Now the company is planning to launch a public car service in the San Francisco Bay Area. Tesla is calling it a “robotaxi” service, but legally, this one will have to use cars with human drivers. The plan appears to put the electric carmaker in murky legal waters in a US state with the country's most tightly regulated autonomous vehicle industry—and where Tesla is already being sued for misleading language around its driver assistance tech.

Very nice I'm a minimalist by nature and typically keep both my menu bar and Dock hidden. That said, I still like having the clock visible at all times. I've tried various widgets in the past to solve this, but none really did the trick—until now. This app nails it. I can still see the clock and date exactly where I want them, and when I move the cursor to the menu bar, the app tucks neatly underneath, just as it should.

We can’t think about rebuilding in the way that things have been in the past. We have to look ahead and say, ‘What is needed? What can people afford?’” Organizations can also use this moment to test and develop emerging technologies that could improve greenhouse-gas measurements, including novel sensors or artificial intelligence tools, Hayes says. “

New types of AI coding assistants promise to let anyone build software by typing commands in plain English. But when these tools generate incorrect internal representations of what's happening on your computer, the results can be catastrophic. Two recent incidents involving AI coding assistants put a spotlight on risks in the emerging field of "vibe coding"—using natural language to generate and execute code through AI models without paying close attention to how the code works under the hood.
