Google is adding a "high-friction" install process for sideloaded apps to educate users about risks. Advanced users can still install without verification, but with extra steps to understand the risks.
PostgreSQL indexes are special database objects that speed up data access by allowing the database to read less data from the disk, but they also incur costs such as additional storage space and maintenance overhead. There are several types of indexes available in PostgreSQL, including B-Tree, Hash, BRIN, GIN, and GiST, each with its own strengths and weaknesses, and choosing the right type ...
The White House posted a manipulated photo of civil rights attorney Nekima Levy Armstrong, making her appear to be crying, after she was arrested for protesting at a church with alleged ties to ICE. Armstrong's lawyer calls the arrest a "farce" and the photo manipulation an "outrageous defamation."
Turbopuffer's ANN v3 technology achieves 100 billion-vector scale at thousands of QPS with 200ms p99 latency. It uses hierarchical clustering, binary quantization, and distribution to maximize hardware utilization and minimize bottlenecks.
Netfence is a daemon that injects eBPF filter programs into cgroups and network interfaces to block unknown traffic. It synchronizes allowlists/denylists with a central control plane via gRPC.
xdgctl is a TUI for managing XDG default applications. It allows setting and viewing file category defaults without using xdg-mime.
Wine-Staging 11.1 is available with 254 patches, including new work for Adobe Photoshop and VKD3D. It's available for testing on WineHQ.org.
BirdyChat now allows users to message WhatsApp users in Europe under the Digital Markets Act. This interoperability feature removes barriers to adoption and keeps work conversations organized.
Plexim has developed PLECS Spice, an extension that brings SPICE device-level simulation capabilities directly into PLECS. This allows engineers to simulate hybrid systems containing both standard PLECS and SPICE circuits within a single tool.
A design mockup for the iRadio, later Envoy, was created by you at frogdesign for Motorola. It featured a hinge and folding mechanism with an internal antenna, later changed to an external one due to reception issues.

The user built an ARM64 assembly lexer for Dart code that was 2x faster than the official scanner but found that I/O was the bottleneck due to syscall overhead. By compressing 104,000 Dart files into 1,351 tar.gz archives, the user achieved a 43x speedup in I/O and a 2.27x total speedup, highlighting the importance of reducing syscall overhead in modern storage systems.
The author is a nostalgic Mac user who misses Apple's Aperture, a professional photo editing app discontinued in 2015. They compare Aperture's efficient design to modern apps like Photos, which require more clicks and navigation.
Lithium-ion batteries are improving in longevity and safety, but their capacity is increasing incrementally. They meet consumer device expectations but need further development for electric vehicles.
The user worked at an Electronics Boutique in 1992 and bought a Sony Data Discman Electronic Book Player DD-1EX for a low price. The device is a mini laptop-like reader with a QWERTY keyboard and lacks data saving capabilities, but has potential as a PDA.
New research from Lloyd's Register found excessive shipboard alarms cause alarm fatigue, disrupting rest periods and eroding trust in safety systems. The study recommends adopting objective alarm performance assessment and human-centred design to reduce alarm loads and improve safety.
SageCompass is a virtual consultant that evaluates AI ideas with numbers to determine their worth. It helps businesses decide if AI is necessary before investing time and money.
Researchers at the Keck School of Medicine of USC found a 1.1% drop in nitrogen dioxide levels for every 200 zero-emissions vehicles added in California neighborhoods. The study, using satellite data, confirms the environmental health benefits of zero-emissions vehicles in the real world.
The user is refurbishing an Apple Network Server 700, a large Unix server from the 1990s, and is testing its functionality with a pre-production ROM that allows it to boot Mac OS. The user has successfully booted the server with the ROM and is now ready to begin experimenting with the ROMs, including a prototype Mac OS ROM that fully supports all internal devices in Mac OS.

Large Language Model inference is challenging due to memory and interconnect issues. Researchers propose four architecture opportunities to address these challenges: high bandwidth memory, processing-near-memory, 3D memory-logic stacking, and low-latency interconnect.
Using Elixir with AI has greatly increased productivity, but it requires a consistent codebase architecture and strict adherence to good Elixir practices to avoid messy code. The AI, Claude, excels at writing code but struggles with decisions and debugging, particularly with concurrent test failures and OTP issues, requiring human intervention to correct its mistakes.
Through the kitchen window, I could see my husband, Rick, in the back yard, his expression grim, his phone pressed against his ear. He was walking in tight circles as he talked, the way he does when he’s stressed. I opened the back door and heard a smattering of ominous, dreary words: Stroke. Fall. Hospital. Rick’s parents were dead. My father was dead. Our aunts and uncles, nearly all dead. ...
