Rowhammer Attacks Now Target NVIDIA High-End GPUs

2025-07-13

Rowhammer Attacks Now Target NVIDIA High-End GPUs

Researchers from the University of Toronto have demonstrated that Rowhammer attacks, previously known to affect standard DRAM, can now target GDDR6 memory on NVIDIA's high-end GPUs when ECC is disabled. This vulnerability exploits a memory bug where repeated access to one memory row causes bit flips in another. NVIDIA recommends enabling ECC for protection, especially crucial for data center admins and workstation users. While newer memory types like GDDR7 and HBM3 have built-in OD-ECC, many users disable ECC for performance or configuration reasons, increasing their risk. Check your ECC status now if unsure!

Turning an Old iPhone into a UniFi Protect Camera with Docker

2025-08-26

The author successfully integrated an old iPhone's camera into their UniFi Protect system using a Docker container. Lacking an iOS app with native ONVIF support, they cleverly used an RTSP app (IP Camera Lite) and an ONVIF proxy Docker container. ffmpeg was used to verify the RTSP stream, and after some configuration adjustments (including specifying the correct width/height), the DIY camera was successfully added to UniFi Protect, replacing their previous Surveillance Station and Scrypted setups.

CVE Program Faces Funding Cliff, Threatening Global Cybersecurity

MITRE's CVE (Common Vulnerabilities and Exposures) program, a cornerstone of global cybersecurity, faces a potential shutdown due to expiring funding from the U.S. Department of Homeland Security. The program assigns standardized identifiers to software vulnerabilities, crucial for communication and coordinated responses. A lapse would severely disrupt vulnerability tracking, patch management, and threat intelligence, impacting governments, businesses, and individuals. While historical CVE data will remain on GitHub, the cessation of new vulnerability assignment would cripple the global cybersecurity community's ability to respond to emerging threats. Experts urge immediate government intervention to prevent catastrophic consequences and advocate for stable, long-term funding to ensure the CVE program's continued operation.

Systemd Service Unit Restrictions: A Common Cause of Daemon Startup Failures

2025-09-20

A classic problem for Linux system administrators is a daemon failing to start normally but working fine when manually run as root. Traditional causes include incomplete $PATH environment variables, SELinux, and AppArmor. Increasingly, systemd service unit restrictions (documented in systemd.exec) are the culprit. Directives like ProtectHome and PrivateTmp can cause cryptic 'permission denied' or 'file not found' errors, or even indirect failures like blocking DNS queries. Removing restrictions from the daemon's .service file can help diagnose the issue, but future daemons may rely on these restrictions, complicating troubleshooting.

The AI Revolution Breaks the Tech Interview – What Now?

The AI Revolution Breaks the Tech Interview – What Now?

The rise of AI has fundamentally broken the traditional software engineering interview process. This article argues that LLMs act as mirrors, reflecting the skill of the operator. With AI easily solving coding challenges, identifying truly skilled candidates is a major hurdle. The author suggests interviews should assess not only theoretical understanding of LLMs (like the Model Context Protocol) but also practical application – observing how candidates interact with LLMs, managing context windows, debugging, critiquing generated code, and demonstrating critical thinking. Learning agility, resilience, and a product engineering mindset are also crucial. While a perfect solution remains elusive, observing candidates' LLM interactions is currently the most effective assessment method. The high cost of this intensive process presents a further challenge.

The Demise of 32-bit Support in the Linux Kernel?

2025-09-02

At the Open Source Summit Europe 2025, Arnd Bergmann, the maintainer of architecture support in the Linux kernel, delivered a talk discussing the potential removal of 32-bit system support. While desktop and server systems have long transitioned to 64-bit, a significant number of 32-bit devices remain in embedded systems. Bergmann noted that while the kernel is still adding support for some 32-bit boards, the number of 64-bit boards supported has significantly surpassed 32-bit ones. He argued that removing 32-bit support is a gradual process, requiring consideration of existing hardware and software support and analyzing user numbers to determine when to remove support for specific architectures. The talk also addressed challenges and solutions related to 32-bit support, such as high-memory support, the year-2038 problem, and big-endian support. Ultimately, Bergmann stated that the kernel will retain support for armv7 systems for at least another ten years, while support for other 32-bit architectures will likely fade away sooner.

Google Cloud's Massive Outage: A Simple Code Error's Catastrophic Impact

Last week's massive Google Cloud outage, lasting several hours and affecting numerous clients including Cloudflare, stemmed from a code change in the "Service Control" component of Google's API management control plane. The new feature lacked proper error handling and feature flag protection, leading to a null pointer exception. This triggered a cascading failure upon a specific policy change, overloading the infrastructure. Google admitted insufficient error handling and monitoring, promising improved external communication and internal processes. However, the incident highlights the vulnerability of even tech giants to large-scale outages.

Slow Mac App Launches: Malware Scan or Hash Cache Miss?

2025-05-01

Blogger Jeff Johnson discovered last year that slow Mac app launches are due to malware scanning by the syspolicyd process. However, blogger Howard Oakley disagrees. Johnson uses spindumps to refute Oakley, showing the malware scan occurs during dlopen when loading dynamic libraries. Oakley claims the slow launches are due to SHA-256 hash cache misses for files in the Frameworks folder. Johnson argues Oakley's theory lacks evidence and ignores the fact that universal binaries contain two architectures, making Oakley's hash calculation time estimates inaccurate. The core of this debate lies in different interpretations of system logs and process snapshots, and differing understandings of caching mechanisms.

First Ever Footage of a Giant New Zealand Snail Laying an Egg

New Zealand's Department of Conservation has captured the first-ever footage of a threatened giant carnivorous snail, Powelliphanta augusta, laying an egg from its neck. Endemic to New Zealand, this snail's habitat was destroyed by mining, leading to conservation efforts. After nearly two decades of care in a controlled environment, rangers witnessed this remarkable event. Hermaphroditic, each snail lays about five eggs a year, with an incubation period exceeding a year. These snails live for 25-30 years, a stark contrast to common, fast-reproducing garden snails. The Powelliphanta augusta faced extinction due to mining but conservation efforts have yielded nearly 2000 snails in captivity.

The Surprisingly Explosive World of Nitrogen Triiodide

2025-06-01

This article recounts a surprising encounter with nitrogen triiodide (NI3), an incredibly unstable compound. The author details an experience where seemingly random bangs in a stairwell were traced to the highly sensitive explosive. NI3's instability stems from the loose bonding of iodine atoms to nitrogen, making it detonate from even minor disturbances like a footstep or air current. The text explains the chemical reasons for its instability and notes its complete lack of practical applications due to its unpredictable detonations. The author concludes with a warning against attempting synthesis and links to safe demonstrations of NI3's explosive nature.

Asteroid 2024 YR4: A Near Miss, But a Valuable Lesson

Asteroid 2024 YR4, once flagged as the highest-ever recorded impact risk to Earth, is back in the news – this time for a slightly increased chance of a lunar impact in 2032. Observed briefly by the James Webb Space Telescope in May, new data refined its trajectory, increasing the lunar impact probability from 3.8% to 4.3%. While a collision is unlikely to significantly alter the moon's orbit and any debris would burn up in Earth's atmosphere, the event served as a valuable real-world test of planetary defense strategies. Initial concerns of a higher Earth impact probability were later dismissed as further data ruled out any risk. The asteroid, roughly the size of a 10-story building, provided scientists with a rare opportunity to practice the entire planetary defense process, from detection and analysis to public communication.

Brian Eno's Art Theory and a Dynamic Model of Democracy

This article explores how Brian Eno's art theory illuminates a new understanding of democracy's workings. Drawing on Adam Przeworski's theory of democracy, the author argues that its game-theoretic stability model struggles to explain the current decline of democracy. Eno's concept of 'generating variety' in artistic creation provides inspiration for a more dynamic model of democracy. This model emphasizes adaptability and responsiveness to endogenous change, rather than a rigid equilibrium. The article uses Eno's analysis of music composition as an example to illustrate this dynamic model and calls for a greater emphasis on diversity and adaptability within democratic systems to meet the challenges of complex environments.
