FiveM: The alt:V Integration Disaster

2025-02-20

This post details the disastrous integration of the former alt:V team into the FiveM project. The ex-alt:V team demonstrated a profound lack of teamwork, ignoring communication and unilaterally altering code and build systems, resulting in numerous regressions. They failed to test their changes, disregarded backward compatibility, and treated the original development team with arrogance. Specific examples highlight the ex-alt:V team's technical incompetence, lack of accountability, and malicious behavior towards the original team. Ultimately, the destructive actions of the ex-alt:V team led to the departure of the original FiveM developers and plunged the project into chaos.

Meta Glasses SDK Plea: Unleashing Developer Potential

A developer is urging Meta to release a developer kit (SDK) for Meta glasses. Currently limited in functionality, the developer envisions a community built around an SDK, leveraging a potential background service API to allow third-party apps to send commands. This would enable voice commands like "Hey Meta" to control smart home devices, for instance. Access to a live camera feed, if provided by the SDK, would unlock countless possibilities. This would greatly enhance the customizability and user experience of Meta glasses.

hk: A Blazing-Fast Rust-Based Git Hook Manager

2025-02-17

hk, a Git pre-commit hook manager written in Rust, prioritizes performance and ease of use. It addresses shortcomings in existing tools like `mise` and `pre-commit`, such as running tasks only on specific file changes and cumbersome plugin management. Using the pkl configuration format and advanced parallel execution logic, hk significantly improves speed. Compared to `lefthook`, hk boasts superior speed and more built-in features, eliminating the plugin reliance of `pre-commit`. Currently in development, hk aims to achieve parity with `lefthook` and `pre-commit` in usability while continuously enhancing performance and features.

Clang Optimization Regression: Inlining Backfires in C++ Benchmark

2025-02-19

A C++ benchmark revealed a performance regression in Clang's optimization of inline functions. When the `increment` function was inlined, branch prediction failures resulted in roughly a 5x slowdown compared to the non-inlined version. `perf stat` confirmed branch mispredictions as the culprit. Interestingly, compiling with the Zig toolchain significantly improved performance, suggesting a potential regression in Clang 19. The issue has been reported on the Clang/LLVM repository, with initial investigation pointing to a trade-off between SROA and SimplifyCFG optimization passes.

Amazon's Drone Delivery Tests Stir Up Neighborhood Disputes

Amazon's drone delivery test program in College Station, Texas, sparked significant backlash from local residents due to excessive noise pollution. Initially, frequent drone flights severely disrupted residents' lives and even affected wildlife. Although Amazon claimed to have implemented noise reduction measures and complied with regulations, residents believed the company made a crucial mistake in locating its drone base near residential areas. Amazon eventually temporarily grounded its drones for a software update and plans to terminate its lease, offering a glimmer of hope to noise-weary residents. The incident raises questions about how tech companies balance commercial interests with public welfare when developing new technologies.

The 15th-Century Google Maps? The Astonishing Piri Reis Map

In 1929, a German theologian stumbled upon a gazelle skin parchment map in Istanbul's Topkapi Palace – the Piri Reis map, created by a 14th-century Ottoman admiral. This map depicts the coastlines of South America and Africa with remarkable accuracy, even hinting at Antarctica, defying the technology of its time. Compiled from at least 20 sources, possibly including a map by Columbus, the Piri Reis map wasn't mere art; it utilized sophisticated portolan charting with compass roses and navigational lines, baffling modern scientists with its precision. It showcases the peak of medieval navigation and exemplifies the power of cultural exchange and human ingenuity.

Online Job Applications: A Waste of Time?

After a pandemic-induced break, the author tried online job applications for the first time, only to be met with overwhelming disappointment. Nearly 1000 applications yielded almost no responses. This led him to conclude that online job platforms are largely ineffective, filled with scams and dead ends. He contrasts this with the far superior approach of networking, building a public profile, and directly contacting target companies. The author likens online applications to throwing a letter into the ocean; ultimately, he found his current job through his network.

Atop 2.11 Heap Overflow Vulnerability: CVE-2025-31160

2025-03-29

A heap overflow vulnerability (CVE-2025-31160) has been discovered in Atop 2.11. The vulnerability stems from Atop attempting to connect to the TCP port of the atopgpud daemon during initialization. If another program is listening on this port, Atop may connect to it and receive malicious strings, leading to parsing failures, heap overflows, and segmentation faults. This vulnerability has been present since the introduction of atopgpud in Atop 2.4.0. The solution involves: not connecting to the TCP port by default, only attempting to connect when the '-k' flag is used; improved string parsing to avoid heap overflows; and not searching for netatop or netatop-bpf by default, only when the '-K' flag is used.

Radiant Foam: Real-time Differentiable Ray Tracing Breaks New Ground

2025-02-04

Researchers introduce Radiant Foam, a novel scene representation combining the efficiency of volumetric mesh ray tracing with the reconstruction quality of splatting methods. Leveraging Voronoi diagrams and Delaunay triangulation, Radiant Foam achieves real-time ray tracing surpassing even hardware-accelerated Gaussian ray tracing in speed while nearly matching Gaussian splatting's reconstruction quality. Avoiding complex acceleration structures and special hardware/APIs, it only requires a standard programmable GPU. This breakthrough promises to advance real-time rendering significantly.

Iron Age Celtic Tribe Centered Around Women, DNA Reveals

A groundbreaking study using ancient DNA has revealed a surprising social structure in an Iron Age Celtic tribe in Britain. Unlike previous prehistoric societies, the Durotriges tribe, dating from 100 BCE to 100 CE, was centered around women. Analysis of mitochondrial DNA showed matrilocal residence, with men moving to their wives' communities. This provided women with strong support networks and significant influence, challenging traditional gender roles and offering a new perspective on ancient social organization. The findings suggest a widespread matrilocal custom across Britain during the Iron Age.

Python Launcher Gains Virtual Environment Support

The Windows installer for Python includes a launcher to locate the correct Python interpreter. However, it previously lacked virtual environment support. PEP 486 proposes making the launcher 'virtualenv aware'. This means that when no specific interpreter is given, the launcher will prioritize the currently active virtualenv, falling back to the default Python if none is active. This simplifies running Python commands within virtual environments, avoiding the need for different commands in different contexts.
