Cursing Your Way to Google Search Results Without AI Summaries

Tired of Google's AI-powered search results leading you astray? It turns out adding expletives to your search query disables the AI-generated summaries. Including curse words prevents Google from displaying its AI Overview at the top of the results, instead providing a standard list of links. While not the first method discovered to bypass Google's AI summaries, this approach is remarkably simple and cathartic. This raises questions about the desirability of these AI summaries; if users consistently seek ways to disable them, does this indicate a lack of demand? While convenient, AI summaries are prone to inaccuracies and may exacerbate the spread of misinformation, mirroring the issues seen with ChatGPT's integration into Siri. Google argues that AI Overviews don't reduce website traffic, a claim disputed by media companies.

Trump Admin Orders Federal Employees to Remove Pronouns from Email Signatures

Multiple federal agencies ordered employees to remove pronouns from their email signatures by Friday afternoon, according to internal memos obtained by ABC News. The directive stems from two executive orders signed by President Trump on his first day in office, aiming to curb diversity and equity programs. Agencies including the Department of Transportation, Department of Energy, and CDC received similar instructions. One CDC employee expressed frustration, stating this had never happened in their decade of service. The Office of Personnel Management also issued a memo directing agencies to review email systems and disable pronoun prompts. This action is the latest in the Trump administration's push to dismantle diversity and equity initiatives within the federal government.

DOJ Claims Money Isn't Property: A Legal Absurdity

In a shocking legal argument, the US Department of Justice (DOJ) claimed that confiscating $50,000 from a small business owner, Chuck Saine, didn't violate his property rights because money isn't property. Their reasoning? The government creates money, can tax it, and the Constitution allows spending for the 'general welfare'. This absurd claim challenges fundamental property rights and has sparked outrage. The case will be decided in court, but the DOJ's argument raises serious concerns about governmental overreach.

FBI, Dutch Police Bust Massive Pakistan-Based Cybercrime Service

2025-01-31

The FBI and Dutch authorities this week dismantled a massive spam and malware distribution service operating out of Pakistan, known as “The Manipulators.” This group, previously profiled multiple times, provided cybercrime tools to transnational organized crime groups. The operation seized dozens of servers and domains, uncovering millions of victim records, including at least 100,000 from Dutch citizens. The service sold phishing kits, scam pages, and email extractors, facilitating Business Email Compromise (BEC) schemes that caused significant financial losses to victims. Ironically, despite their brazen public profile and past media attention, The Manipulators showed little regard for protecting their own or their customers' identities, leading to their downfall. This represents a major blow to cybercrime, but investigations are ongoing to track down buyers of their services.

The Stack Unwinding Conundrum in Perf

The Stack Unwinding Conundrum in Perf

Perf, a powerful performance analysis tool, uses PMU counter overflow interrupts to capture thread states for profiling. However, stack unwinding presents a challenge. Modern compilers omit frame pointers by default, making stack backtracing difficult. While recompiling with -fno-omit-frame-pointer is possible, it's expensive and can lead to system library incompatibilities. DWARF offers an alternative, but its complexity and performance overhead are substantial, leading Linus Torvalds to reject its use in kernel stack unwinding. Perf thus employs a compromise: copying only the top portion of the stack to userspace for unwinding. This limits stack size (65,528 bytes) but effectively balances performance and practicality.

Savile Row Tailors Face Ozempic-Induced Crisis

Savile Row Tailors Face Ozempic-Induced Crisis

Savile Row, the home of bespoke tailoring, is facing an unprecedented crisis, not from high rents or taxes, but from the popular weight-loss drug Ozempic. The drug's dramatic weight loss effects are forcing clients to have their expensive, custom-made suits drastically altered or remade. Tailors are facing a double challenge: time constraints and staffing shortages. Altering a suit can cost £1,600, while a replacement is £5,000-£7,000. Many clients own numerous suits and are reluctant to discard them, further increasing the tailors' workload. The issue extends beyond suits to shirts, which lack the internal space for adjustments. Tailors worry about weight rebound once clients stop using the drug, creating a potential 'Part 2' to this story.
