I strongly agree, having worked quite a bit in several languages including Python/NumPy/Pandas, MATLAB, C, C++, C#, even Perl ... I am not sure about Julia, but last time I looked at it, the language designers seemed to be coming

Isn’t this pretty traditional stuff? What is modern about it? Does any of this map to a GPU for column-oriented analytical data processing? Basically, machines are only good at reading and writing large, contiguous chunks of data. As these

Temenos T24 core banking software is based on something even older than COBOL called MultiValue. This is a “pre-relational” database (now unironically rebranded “post-relational/NoSQL”). I hear Temenos also has an innovation App Store
