How FOSS Projects Handle Legal Takedown Requests

news.ycombinator.com Unknown 2025-09-28 23:22:38

When a legal takedown request arrives, whether it’s about copyright, censorship, privacy, or something more vague, how a Free and Open Source Software (FOSS) project responds can make all the difference. Handled well, a takedown request can be a manageable administrative step. Handled poorly, it can cause panic, disrupt infrastructure, or even put contributors at legal risk. As part of our legal resilience research, we spoke with a range of legal experts, software freedom advocates, and mainta

Requiem for an Exit

news.ycombinator.com Unknown 2025-10-07 10:08:20

Between 1994 and 2004, Frode Oldereid and Thomas Kvam created a series of robotic installations exploring the intersections between technology, ideology, and collective memory. These robots evoked the aesthetics of political mass movements, echoing the fractured language of 20th-century totalitarianisms and its countercultures. Two decades later, the artists revisit these themes in Requiem for an Exit. At the center of the installation stands a towering robotic figure, four meters tall—a skelet

What Is the Fourier Transform?

news.ycombinator.com Shalma Wegsman 2025-10-12 00:11:09

As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure waves of many different frequencies. When the combined sound wave descends through the ear canal and into the spiral-shaped cochlea, hairs of different lengths resonate to the different pitches, separating the messy signal into buckets of elemental sounds. It took mathematicians until the 19th centu

These psychological tricks can get LLMs to respond to “forbidden” prompts

arstechnica.com Unknown 2025-10-14 20:32:12

If you were trying to learn how to get other people to do what you want, you might use some of the techniques found in a book like Influence: The Power of Persuasion. Now, a pre-print study out of the University of Pennsylvania suggests that those same psychological persuasion techniques can frequently "convince" some LLMs to do things that go against their system prompts. The size of the persuasion effects shown in "Call Me A Jerk: Persuading AI to Comply with Objectionable Requests" suggests

The repercussions of a typo in C++ & Rust

news.ycombinator.com Unknown 2025-10-17 07:22:01

The repercussions of missing an Ampersand in C++ & Rust Copying vs Passing by reference TL;DR There’s a funny typo that causes someone to copy data instead of “referencing” in C++. Rust is nice because it provides defaults that protect you from some of these “dumb” mistakes. In this example, I’ll go over how the “move by default” can prevent us from introducing this subtle behavior. Motivation I originally hesitated to write this because I thought the topic was too “obvious”, but I did it a

The UK government continues to seek access to Apple's iCloud services, according to a new report, with its request to access people's data seemingly even broader than originally thought. According to a legal filing seen by the Financial Times, the UK Home Office wanted backdoor access to standard iCloud services in addition to those secured with the highest level of encryption.

Resident Evil Requiem feels very familiar, but it's so well made that I respect the hell out of it

engadget.com Unknown 2025-11-07 14:00:22

For nearly 30 years, developer Capcom has been redefining its particular brand of survival horror for the Resident Evil series. Despite its tone shifting between action-horror games and more pure horror entries, where players face down grotesque moments with scant resources, the series still manages to place players in tense encounters that define the series' against-all-odds approach to horror. And with the upcoming Resident Evil Requiem — or RE9 — appears to continue the series' current moment

AWS pricing for Kiro dev tool dubbed 'a wallet-wrecking tragedy'

AWS has introduced new pricing for Kiro, its AI-driven coding tool, but unlike the pricing originally announced, the latest plans are "a wallet-wrecking tragedy," according to many of its users. "Kiro's spec-driven AI IDE is a gem," said open source PHP and Laravel engineer Antonio Ribeiro on GitHub, "until I saw your new pricing." AWS introduced Kiro last month as a fork of Code OSS (also used by Visual Studio Code) with a distinctive approach to AI coding assistance, based on specifications

Cross-Site Request Forgery (CSRF) is a confused deputy attack where the attacker causes the browser to send a request to a target using the ambient authority of the user’s cookies or network position. For example, attacker.example can serve the following HTML to a victim <form action="https://example.com/send-money" method="post"> <input type="hidden" name="to" value="filippo" /> <input type="hidden" name="amount" value="1000000" /> </form> and the browser will send a POST request to https://e
