Saying Goodbye to try_files: Optimizing Nginx Performance

This article delves into the performance implications of the try_files directive in Nginx. While try_files handles SEO-friendly URLs, it incurs unnecessary disk I/O for file existence checks, impacting performance. The article advocates for a framework-specific approach (e.g., leveraging WordPress's /wp-content/ directory) to configure Nginx directly, allowing Nginx to serve static files without try_files. A Python script is also provided to automate the generation of Nginx location blocks for various static file types, further enhancing efficiency and security.

Modules Begone: A New Programming Paradigm Based on a Global Function Database

2025-04-04

This article proposes a revolutionary programming paradigm: abandoning modules in favor of a global function database. All functions have unique names and rich metadata, stored in a searchable key-value database. This simplifies open-source contributions (contributing a single function is sufficient), eliminates the module partitioning problem, and facilitates function lookup and reuse. The author argues that this approach is more beneficial for the development and maintenance of large programs and proposes specific implementation ideas and extensions, such as function rating and peer review mechanisms.

Coder's Million-Dollar Mistake: A Bug with a Dramatic Twist

Trey, a programmer working for a 3G telecom startup, wrote an automated payment testing program intended for small test transactions. Three bugs in the code, however, caused the program to credit his test account with $100 every five minutes. A lack of liveness check meant that when one gateway failed, the program continued running for hours, accumulating a substantial sum. The next morning, Trey faced questioning from the security team until his department head explained the situation, but the test account balance was reset to zero.

Don't Use Cosine Similarity Carelessly!

This article explores the risks of over-relying on cosine similarity for vector comparisons in data science. The author argues that while computationally simple, cosine similarity often fails to capture semantic similarity and can be easily misled by superficial patterns like writing style and typos. The article uses examples to illustrate this problem and proposes several improved methods, including: directly using LLMs for comparison, fine-tuning or transfer learning to create task-specific embeddings, pre-prompt engineering, and text preprocessing. The author emphasizes the importance of choosing appropriate similarity metrics based on specific needs, rather than blindly using cosine similarity.

Running Qt Applications as Non-Root Users in Embedded Linux with Wayland

Embedded Linux systems often run Qt applications as root, posing a security risk. This article details a solution to run Qt applications as a non-root user (weston) within a Yocto-built system using Wayland. By modifying the Weston and Qt application service units and configuring the `XDG_RUNTIME_DIR` and `WAYLAND_DISPLAY` environment variables, the article ensures both the Wayland server and clients use the same socket file, enhancing security and complying with the EU Cyber Resilience Act. Key steps include altering the user and group in weston.service and weston.socket, and generating the weston-client environment file within weston-init.bbappend. This effectively allows Qt applications to run without root privileges.

The Curious Case of the Converging UNIX Workstation

2025-07-20

The author, having amassed a collection of 1990s RISC/UNIX workstations from SGI, HP, and DEC, noticed a peculiar trend in their internal layouts after watching a video on PC case history. Early models adhered to traditional VME bus designs. However, later models surprisingly adopted a layout reminiscent of the LPX standard – a flat motherboard with rear I/O and a left-side expansion slot. This bears a striking resemblance to contemporary PC designs. The author speculates on whether this was independent convergence or a collaborative effort, leaving the question of coincidence versus design trend unanswered, but prompting intriguing questions about the evolution of hardware design.

Havana Syndrome: Intelligence Agencies Shift Stance on Mystery Weapon

Two years ago, US intelligence agencies emphatically concluded that "Havana syndrome" wasn't the work of a foreign adversary wielding some kind of energy weapon. New intelligence has overturned that conclusion. Some intelligence agencies are no longer ruling out the possibility of a mystery weapon, with the White House even suggesting a deliberate attack by a US foe. This shift is significant, potentially leading to a strong US response. While the new report acknowledges uncertainty, the move from outright denial to a 50% chance is noteworthy.

El Salvador Ditches Bitcoin as Legal Tender: A Failed Economic Gamble

El Salvador, the first country to adopt Bitcoin as legal tender in 2021, has reversed course. President Nayib Bukele's economic gamble has failed, with Bitcoin never gaining widespread adoption among Salvadorans and the planned Bitcoin City remaining unbuilt. A revised Bitcoin Law removes the definition of Bitcoin as 'currency,' though it remains 'legal tender,' effectively allowing refusal of Bitcoin payments. This reform was a key condition for El Salvador to receive a $1.4 billion loan from the International Monetary Fund (IMF). While the government claims it will continue holding Bitcoin reserves, the move is criticized for its lack of transparency and highlights flawed economic decision-making by the Bukele administration.

Typo-Squatting Attack Steals GitHub Credentials via ghrc.io

2025-08-25

A simple typo, 'ghrc.io' instead of 'ghcr.io', has led to a malicious attack stealing GitHub credentials. The attacker uses 'ghrc.io' to mimic GitHub's container registry, ghcr.io. While seemingly a default Nginx installation, 'ghrc.io' responds to OCI API requests (/v2/) with a 401 Unauthorized error and a www-authenticate header, directing clients to send credentials to https://ghrc.io/token. This cleverly mimics legitimate container registries. Logging into 'ghrc.io' results in credential theft. Attackers could use these credentials to push malicious images or directly access GitHub accounts. Check if you've logged into 'ghrc.io' and change your passwords and PATs immediately.
