Also: The first 5 Linux commands every new user should learn Since then, I've always been vigilant about checking for bad blocks and sectors on hard drives.

Microsoft has announced that it will start disabling external workbook links to blocked file types by default between October 2025 and July 2026. After the rollout, Excel workbooks referencing blocked file types will display a #BLOCKED error or fail to refresh, eliminating security risks associated with accessing unsupported or high-risk file types, including, but not limited to, phishing attacks that utilize workbooks to redirect targets to malicious payloads.

Fintech dystopia

"Just like beauty, efficiency, competition, and security are all in the eye of the beholder. For example, one person’s “efficiency” may be another person’s “dismantling critical government infrastructure.” And yet technological solutions designed to make things more efficient, more competitive, or more secure are often presented by Silicon Valley as neutral and universally desirable. That veneer of neutrality and universality can be dangerous if it disguises the fact that Silicon Valley is solvi

Tech Companies Are Blocking Microsoft’s Creepy ‘Recall’ Feature

Microsoft’s much-maligned Recall feature, which automatically screenshots everything you do on your Copilot+ PC to create a “photographic memory,” is not making many fans across the app developer community.

Cloudflare Starts Blocking Pirate Sites for UK Users

Cloudflare has become the first internet intermediary beyond local residential ISPs, to block access to pirate sites in the UK. Users attempting to access certain pirate sites are greeted with 'Error 451 - Unavailable for Legal Reasons'. In theory, ISP blocking should prevent UK users from even seeing this notice, but a combination of Cloudflare's blocking mechanism and choices made by some VPN users results in a piracy dead end. Internet service providers BT, Virgin Media, Sky, TalkTalk, EE, a

The SEC Is Crashing the Digital Stocks Party

For years, the promise of blockchain technology has captivated the financial world, hinting at a future where traditional assets are transformed into nimble, digital “tokens.” This vision, as the U.S. Securities and Exchange Commission (SEC) Commissioner Hester Peirce puts it, is “enchanting, but not magical.” She just sent a clear message to anyone hoping blockchain would free them from financial regulation: not so fast. Commissioner Peirce acknowledged the promise of tokenization, the process

Cloudflare wants Google to change its AI search crawling. Google likely won’t.

After Cloudflare started testing new features that would allow websites to block AI crawlers or require payment for scraping, the tech company immediately faced questions over the logistics of the plan.

Last week, a travel blogger raised questions about the bl

Exploring the Complexity of Distributed Consensus Algorithms in Blockchain

Consensus in blockchain isn’t just a technical problem—it’s an intellectual minefield. You’ve got decentralized nodes spread across the globe, each operating under different assumptions, with varying latencies, incentives, and potential motivations, and yet they’re all expected to come to the same conclusion about the state of a distributed ledger. No central authority, no fallback mechanisms, no easy resets. Just code, cryptography, and coordination dancing on the edge of chaos. It’s beautiful

Trump Officials Want to Prosecute Over the ICEBlock App. Lawyers Say That’s Unconstitutional

A spokesperson using ICE's general press email referred WIRED to a statement issued by acting director Todd M. Lyons on June 30, but did not provide further comment. The White House did not immediately respond to WIRED’s request for comment.
