Do you know how many ways we can implement a filter function in C++? While the problem is relatively easy to understand - take a container, copy elements that match a predicate, and return a new container - it’s good to exercise with the C++ Standard Library and check a few ideas. We can also apply ...

AI coding agents take the shortest path to done, which usually means skipping the specs, tests, and reviews that make software reliable at scale. Agent Skills encodes those senior-engineer behaviors as workflows the agent has to follow, with anti-rationalization built in.

png-cmp is a program I built that checks if two PNGs are visually equivalent. It’s inspired by the cmp command. Here’s how you use it: png-cmp a.png b.png Like cmp, it silently exits if the images are identical, and gives an error if they’re different. Unlike cmp, it checks pixel data, not binary da...

This is a brief and simple [1] explanation of how to adjust the standard sinusoid sin(x) to change its amplitude, frequency and phase shift. More precisely, given the general function: \[s(x)=A\cdot sin(w\cdot x+\theta)\] We’ll see how adjusting the parameters , and affect the shape of s(x). Each se...
