I delivered this talk at SAP Inside Track Berlin in September 2018. The audience was mostly enterprise developers, almost all of them specifically working with SAP as a platform.
Given how many companies I’ve seen flirting with the idea of distributed ledgers, I thought it would be useful to give people an idea of which cases I see as being a good fit for them, to give them a leg up the next time it enters the discussion.
I got invited to speak at Monkigras 2018, a superb conference on software, technology and craft. This year’s theme was “Sustaining Craft”. I wrote and delivered It’s about the curry - you’ll find a (close enough) transcript below.
I’ve been advising a startup on the data transformation space. As part of this, we re-wrote the core engine in Clojure. The new version is, at the worst case, 16 times as fast in the same hardware, and in some cases over 200 times faster. And it does it with a fraction of the lines of code.
We did this in under 3 months of part-time work. We couldn’t focus our entire attention on it, as we had other concerns as well - I was involved with general team and management tasks, and the second developer was helping on other internal projects as well. To further raise the bar: we had to keep it functionality-compatible with the current version, so I had to get acquainted with the existing feature set, and it was the other developer’s first Clojure project.
Clojure made our lives so much easier. But this is not a post about why Clojure is cool.
Interruptions are one of the best ways to squander time and money, but the value chain is not always obvious. This handy guide will help you make the case for why you should be interrupting your developers (nay, any employee!) regularly.
Have you gone over the fundamentals on Reading Clojure? Did you shake off that preconception that there’s some magic syntax to declaring and evaluating things beyond the list?
Great! Let’s now go over other things you might encounter when looking at a random source file. I’m first going to give you an overview of types and related things. After it, we’ll then we get into the good stuff like going over a project, and the weird stuff like ->, ->>, #, the quote and other squiggles.
Back in early December I held a Clojure workshop for the Bucharest Functional Programming meet up. Having to explain the language to developers who were completely new at it was an interesting experience. I decided to start from the ground up: how to even read the blasted thing.
