Formatting Is Unreasonably Expensive for Embedded Rust
As a (late) part of the #rust2020 request, I wanted to talk about one of the paper-cuts that has become decently problematic for new and experienced users of Embedded Rust: The size costs of formatting in Rust today are unreasonably expensive for users of Rust on bare metal embedded systems. In particular there are…

An Introduction to Vectorization
Your CPU has a 32-bit addition instruction that computes the sum of two 32-bit integers x and y, producing a 32-bit result. (The 33rd bit of the sum, the "carry bit", is usually thrown away.)

Race Condition vs. Data Race (2011)
It’s terribly punny/dorky of me, but reading your post it just occurred to me one could start a blog called “Race Condition” about being a person of color and being a computer scientist.

JavaScript Array.push is 945x faster than Array.concat
It took six whole seconds to merge 15,000 arrays with an average size of 5 elements with .concat. What the hell is the Javascript's .concat method doing under the hood?

A Fairly Fast Fibonacci Function
A common example of recursion is the function to calculate the $n$-th Fibonacci number: def naive_fib(n): if n < 2: return n else: return naive_fib(n-1) + naive_fib(n-2) This follows the mathematical definition very closely but it’s performance is terrible: roughly $\mathcal{O}(2^n)$. This is commonly patched up with…
