Peter Ritchie @peterritchie.com · 8hInteresting, you're looking at a preview of a document in Github and in that document there's a link to itself? I've often though Github's editor could do a better job of managing state, but that one is new to me 😮 100
Peter Ritchie @peterritchie.com · 11hSIMD is a small subset of parallelization scenarios. Designing parallelization only for SIMD misses the point. 010
Peter Ritchie @peterritchie.com · 12hIt should be an implementation detail. The design of an application should enable the utilization of SIMD. Maybe his frustration is that many people don't know how to design software to be parallelized. Knowing SIMD doesn't help that because people don't write in assembly :/ 110

Peter Ritchie @peterritchie.com · 14/09/2026Should be fun to watch, considering programming languages have had a `let` keyword since the 1960s that states/declares a named variable and assigns it a value--making a function named "LET" that creates a named variable with a value seem obvious. 🤷🏽 130
