DConf 2019: All Spreadsheets Must Die -- Robert Schadek

Easy to the uninitiated sure - and that's not a bad thing - but anything that needs maintaining (in a professional sense) shouldn't be in a spreadsheet. I realize this is an unrealistic proposition, but think of all the principles we've developed (as an industry) that spreadsheets violate - no separation of code and data, prone to repetition etc. [VIDEO] There was a talk at DConf about this with a bit more depth than what I've written here, and potential replacements

Symmetry Investments | Senior Software Engineers and DevOps | REMOTE or VISA (London, Hong Kong, Singapore) | D, Julia, other functional and systems languages | Full-Time, Fixed Term, Flexible Symmetry Investments is a post startup c. 5bn alternative asset management company with around 175 people across multiple time zones and locations. Our core technology team has been remote first for some time, and the whole company is following suit, post-COVID. I'm one of the three people running the firm, responsible amongst other things for technology across the firm and I’m posting this myself. That should give you an idea both about how seriously we take technology and the culture of the firm. We are three years into a period of transformation from initially a fairly standard enterprise finance approach to technology to something new that recognises the importance of both the humane and the technical for discretionary portfolio management and for the business of running an alternative investment manager. It's not easy to integrate practitioners who may spend most of their day programming but are oriented towards solving their business problems with developers who are specialists in programming. To achieve this, we wrote a little functional DSL that's now in production. Type inference of returns and parameters using inequality constraints is in a feature branch and there is plenty more to do on the language itself as well as the ecosystem around it. What might be a project in itself
