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 ...
Create a tabbed interface with customizable tabs, icons, and dirty indicators, allowing for horizontal or vertical splitting of panes. Implement a tab controller protocol to manage tabs and panes, with optional callbacks for tab bar events.
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.
Products come and go. This is a truism of the internet. Do not expect any particular service to exist forever, or you will be burned. It can be a depressing thought. So much of our lives are lived online. Communities and culture are created online. The play is performed on stages we call "social media". But then they go away. We make our homes on these platforms. Set up shop. Scale a ...
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.

One authentic relating game I enjoy running is "Constellations". The rules are simple: someone calls out a prompt, everyone in the room identifies the person for whom this prompt fits the best, and then places a hand on that person's shoulder. You can only put your hands on one person, and that one person can be yourself. If you want to abstain, you can put your hands behind your ...

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.
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.
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.
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.
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.

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.
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.
