A practical look at when to use macros and when to stick with functions in Rust, using a real FFI example (void_ptr) to show why macros don’t magically make your code faster — and why small helper functions often compile to identical machine code.

Rust’s ndarray crate is a powerful foundation for numerical and scientific computing — but just like with any data‑heavy workload, performance depends heavily on how you write your loops. To explore this, I built a small educational demo that evaluates 10 different techniques for adding two 2D matrices (Array2)

Recent releases of FAR (6644 and newer) crashed with ConEmu in attempt to start editor (F4). Below is detailed info and how to fix.

Rust provides strong guarantees about memory safety, alignment, and the behavior of references. However, when you step into the world of low‑level programming — manual allocation, pointer arithmetic, and raw memory manipulation — it becomes your job to uphold these guarantees. One interesting challenge: Can we intentionally place a u32 at an odd address and still read it safely?

Rust is very strict about memory safety, especially when it comes to unaligned data. If you’ve ever worked with byte buffers, binary protocols, FFI, or #[repr(packed)] structs, you’ve probably run into an error like: “error: Reference to field of packed struct is unaligned”

This is Rust politely telling you: “Stop! Creating a reference here would be undefined behavior.”

In this article, we’ll look at why this happens and how Rust’s addr_of! and addr_of_mut! macros let you safely work with potentially unaligned or unsafe memory locations without creating invalid references.

Computing the base‑2 logarithm of an integer (more precisely: finding the index of the highest set bit) is a common operation in systems programming, graphics, data compression, and low‑level algorithms. While Rust provides methods like u32::leading_zeros(), sometimes you may want your own implementation—especially an approach that is branch‑free, fast, and works on all stable targets.

Many engineering teams inherit or maintain systems built on NI Vision (National Instruments Vision Development Module) and Intel IPP (Integrated Performance Primitives). These C libraries are widely used in industrial imaging, automation, robotics, and high‑performance signal processing.

The lock screen isn’t just a pretty picture — it’s also an extra step before you can enter your password or PIN.

Starting with Windows 8, you have to press any key or click the mouse to move past the lock screen. In some cases, this can even slow things down — for example, after waking the system from sleep.

How image enhancements for x-ray inspection was done over 40 years ago.

Occasionally read a book “Numerical Methods and Fortran Programming with applications in engineering and science” written by Daniel D. McCracken in 1965 and found beautiful example of the punched perforated cards

Sometimes it’s necessary to inspect the machine code behind a LabVIEW-generated executable. Running such an application under a binary debugger is straightforward; locating the desired code is only slightly tricky.

I ran my own experiments to better understand how Hyper-Threading works internally on Windows, using hand-written assembly benchmarks — from single-register multiplications to SHA-256 hashing.

From time to time, I need to fill images with random values — and do it quickly. There are two simple yet elegant algorithms to achieve this.

I just encountered an interesting exception in LabVIEW when the Median Filter was called for a float image containing a NaN value. It works as expected for small images, but I found one that caused a crash.
