The Spanish government has blacklisted Palantir Technologies from public and private state-controlled companies due to concerns over the potential misuse of classified national security information. This directive, issued by the prime minister's office, impacts major entities like Telefónica, Indra, and Navantia, disrupting ongoing projects such as a near-finalized deal with Navantia and a vetoed Guardia Civil collaboration. The ban reflects broader European regulatory pushback against Palantir, mirroring similar moves in France and Germany. Despite the blacklist, Palantir retains a €16.5 million defense contract with Spain's military intelligence center (CIFAS) set to expire in November, with military leadership advocating for renewal. The decision coincides with geopolitical tensions between Spain's prime minister and the incoming U.S. administration, prompting Spain to accelerate investment in domestic technology, including €115 million for Catalan firm Openchip, to enhance data sovereignty.
Hacker News comments largely applaud Spain's move as a step toward national sovereignty and digital independence, with users expressing hope that other European nations will follow suit. Some commenters question the specificity of the ban, suggesting it targets Palantir due to its ties to the incoming U.S. administration rather than broader security concerns, while others call for a full proscription of the company. Skepticism about Palantir's effectiveness is countered by arguments that its operational superiority makes it difficult to replace, with one commenter noting Europe must address this to avoid falling behind. Geopolitical friction is a recurring theme, with predictions the ban might be revoked post-2027 and criticism of Spain's potential reliance on Huawei's equivalent technology. There is also debate about Palantir's ethical standing, with comparisons to authoritarian regimes and criticism of its CEO's public demeanor.

The article reports a security regression in Linux 6.9 where LUKS suspend-to-RAM (STR) stopped wiping disk encryption keys from memory. Prior to this version, the `cryptsetup luksSuspend` command was designed to clear the master key from RAM during STR, but the behavior was inadvertently removed during kernel refactoring. This leaves encryption keys vulnerable to cold-boot attacks if an attacker gains physical access to a suspended, still-powered laptop. The issue does not affect suspend-to-disk (hibernation), where RAM is written to encrypted storage and cleared. The regression was identified through automated testing (e.g., NixOS tests) and has since been patched in Linux 6.10.
Hacker News comments clarify that the vulnerability is specific to suspend-to-RAM, not hibernation, as the master key must remain in RAM for quick resume. Users debate whether this is a kernel-wide flaw or Debian-specific (where `luksSuspend` is an unsupported extension), with some arguing Debian’s patch implementation rather than the core kernel is at fault. Mitigation suggestions include enabling hardware memory encryption (e.g., Intel’s Total Memory Encryption), using TPM features to force RAM wipes on reboot, or configuring hibernation instead of STR. Discussions also highlight broader concerns about Linux kernel security testing, with one user noting that critical bugs often stem from "missing single-line C checks" and advocating for better automated verification. Practical perspectives include reassurance that basic disk encryption suffices for casual security needs, while others emphasize that STR should never be used for high-risk scenarios.

The article "How to ask for help from people who don't know you" outlines the principle of putting yourself in the other person's mind when making requests. Key heuristics include establishing credibility through proof of work (like showing trained models or thoughtful blog posts), explaining context concisely by connecting to what the person already knows, making requests specific and bounded rather than open-ended, and making it easy to decline. The author emphasizes that help freely given is more valuable than help given under pressure, and that all requests should be grounded in honesty, with the core principle being thinking from the reader's perspective.
HN commenters expanded on the article with practical insights, emphasizing authenticity in proof of work beyond surface-level displays. Many highlighted the importance of demonstrating self-sufficiency before asking for help, with one commenter contrasting job referral requests versus showing specific work done on relevant problems. Additional techniques emerged, including offering to pay upfront for consultations, citing specific work of the person being approached, and keeping communication concise. Some commenters provided alternative perspectives, questioning the "show you're worthy" approach and calling for more advice on giving help effectively. Cultural considerations were also noted, such as a tip for asking help while traveling in foreign languages by skipping the language question entirely.

On April 13, 2026, Virginia Governor Abigail Spanberger signed S.B. 388 into law, amending the Virginia Consumer Data Protection Act (VCDPA) to prohibit the sale of geolocation data effective July 1, 2026. Virginia defines "sale" narrowly as the exchange of personal data for monetary consideration, distinguishing it from broader definitions in Maryland and Oregon, which include other valuable consideration. Virginia joins Maryland and Oregon in implementing such bans, while California, Massachusetts, Vermont, and Washington State have proposed similar legislation. This regulatory trend follows heightened scrutiny, including a 2025 California Attorney General investigation into location data and a 2024 FTC settlement banning a data broker from selling geolocation data.
Hacker News commenters raised concerns about enforcement loopholes, such as companies circumventing bans by reclassifying data as free or bundling it with high-cost services. Enforcement challenges were discussed, particularly for Delaware-incorporated companies collecting data in Virginia but operating outside the state. Commenters highlighted historical abuses of location data, including car insurance companies tracking driving behavior and a 2024 case where location data was used to target individuals near Planned Parenthood facilities. Some argued the ban is insufficient without also prohibiting the sharing of geolocation data, while others noted potential distinctions between "precise" geolocation data (e.g., device-reported) and broader IP-based location data. Calls were made for stronger penalties and criminal prosecution for deceptive data collection practices.

The article argues that 24-bit/192kHz music downloads offer no audible benefits over standard CD-quality 16-bit/44.1kHz audio and introduce practical drawbacks. It explains that the human hearing range is limited to approximately 20Hz–20kHz, making ultrasonic frequencies inaudible. These ultrasonics can cause intermodulation distortion in playback equipment, slightly degrading fidelity. The author cites scientific evidence, including a double-blind ABX test where listeners could not distinguish high-resolution audio from 16-bit/44.1kHz versions. Additionally, 24-bit/192kHz files require 6x more storage space without improving perceptual quality. The author critiques audiophile myths about "golden ears" and highlights that 24-bit depth is only useful for recording/mastering headroom, not distribution. Genuine improvements for audio quality are identified as better headphones, lossless formats, higher-quality masters, and surround technologies like Ambisonics.
HN comments largely dismiss 24/192 as audiophile pseudoscience and marketing, comparing it to "healing crystals" and scams like "low-oxygen cables." Many note the irrelevance of high resolution for end-users, emphasizing that 24-bit is practical only for production stages. Users highlight confirmation bias and placebo effects in listening tests, reinforcing the need for double-blind methodologies like ABX testing. Technical discussions include critiques of audiophile gear claims (e.g., "continuous RAM" players) and observations that ultrasonics might cause negligible distortion but never enhance sound quality. Some debate whether better masters or formats (like FLAC) are more impactful than resolution hikes. Overall, the consensus frames the 24/192 trend as a solution to a non-existent problem driven by commercial interests, with skepticism toward unsubstantiated audiophile assertions.
