Revisiting the NetBSD build system

Blog System/5 • 1571 implied HN points • 28 Dec 24
🕹 Technology Software Open Source Operating Systems Development Tools Embedded Systems
  1. NetBSD's build system is powerful and flexible, allowing users to build the operating system from scratch on any supported hardware without needing root access. This makes it useful for developers and advanced users.
  2. The build process is user-friendly due to the `build.sh` script, which simplifies complex commands into easy-to-understand goals. You can easily compile and create disk images with just a few commands.
  3. While the build system has many strengths, it also has inefficiencies, especially with incremental builds. Improvements could make it faster and less resource-intensive, which is a consideration for future development.

Rust: future cannot be sent between threads safely

Art’s Substack • 39 implied HN points • 24 May 24
🕹 Technology Programming Concurrency Error Handling Development Tools
  1. In Rust, sending futures between threads safely can lead to compilation errors. This can happen when sharing mutable data across threads that must be protected with a Mutex.
  2. The issue with sending futures between threads safely is due to the fact that futures in Rust are required to implement the 'Send' trait. Problems arise when trying to hold a MutexGuard across an await, causing the future not to be Send.
  3. To resolve issues related to sending futures between threads safely in Rust, one solution is to explicitly introduce a scope to handle locking and unlocking of the MutexGuard around the await, ensuring that the future is 'Send'.

🕹 Technology APIs Documentation Security Development Tools
  1. API documentation can be tailored for different users to protect sensitive operations. This is important because revealing too much information can become a security risk.
  2. Using multiple OpenAPI documents can be challenging to maintain, as changes need to be updated in each separate document.
  3. OpenAPI Overlays help manage different user needs without complicating maintenance. They allow adding or changing API operations based on user types easily.

Quality Engineering Basics: Debugging

QUALITY BOSS • 19 implied HN points • 12 Feb 24
🕹 Technology Software Testing Quality Assurance Debugging Development Tools User Experience
  1. Debugging is like being a detective; you need to find clues to solve the problem in the software. Understanding how or when a bug happens can help get it fixed faster.
  2. A good bug report includes details like when the bug occurs and what steps to reproduce it. The more information you provide, the easier it is for developers to understand and fix the issue.
  3. Trying different methods and tools can help uncover more about the bug. For example, using different browsers or versions of software can help pinpoint what's causing the problem.

🕹 Technology Software Embedded Systems Programming Development Tools C++
  1. Qt 6 is not yet ready for embedded systems. Many needed features are missing and won't arrive until Qt 6.2, which means developers should stick with Qt 5.15 for now.
  2. C++ property bindings are an exciting new feature in Qt 6. They make code easier to work with by automatically updating properties when related data changes.
  3. Migrating applications from Qt 5 to Qt 6 can be done step by step using the Core5Compat library, which helps manage outdated classes and reduce errors during the transition.
