Cheap integration tests is usually an oxymoron (when cheap refers to the tightness of the developer feedback loop). Gary was coming from the land of Ruby-on-rails where a full set of integration tests could take hours. In that environment,

Sandi mentions this during a talk she gave on refactoring a few years ago. [0] It’s a great little video for showing junior developers how a messy bit of code can be cleaned up with a few well chosen OOP patterns (and a set of unit tests to

Not sure where the hostility is coming from. I didn’t read anything disparaging about Haskell in hencq’s comment. He/she just made a factual statement about Clojure’s approach to data types being analogous to Unix/strings when it

Rather than just looking at the home page for Crux (which has a lot of impressive tech jargon), I recommend that you watch the related video, “Temporal Databases for Streaming Architectures”, on YouTube which I found did a much better job o

Document DBs are ok if you only ever want to use the data in the same way that you stored it. There are definitely use cases where that makes sense, but you lose a lot of query power when compared to a relational database, which makes it l

Yes, as I said in my original post (and others in this thread), you can absolutely come up with elegant solutions to this in other languages. In my experience though, for every one elegant solution like yours, there will be ten developers

I agree, I wouldn’t suggest Clojure for a large company with lots of junior developers. I wouldn’t suggest Java either, though. Go would be a better fit for that situation these days. I look at Clojure and Go as different sides of a coin. O

That’s great if your dealing exclusively with CSV files and a fixed set of data types, but the point is that this approach in Clojure is universal regardless of where the data is coming from, or going to. Everything comes in as a map, gets

Well, you can write code a lot like this in JavaScript using a library like Ramda, and get a lot of the benefits. But then everyone that you on-board to that project has to be up to speed with how the code is being written and why. With Clo

Assuming that you are mapping the results to a Dictionary, sure it would be similar. My point was more that C#/Java developers (myself included at one point in time) would typically reach for classes to store the results, rather than j

You could definitely do something like this in other languages, probably even in Java/C# using a HashMap or Dictionary, but the difference is that this is “the way” you would do this in Clojure. It’s not, generally speaking, they way y

It may look terse, but its not code golf. Any Clojure developer would understand what this does (its actually pretty straight forward), but to an outsider, it definitely looks strange. Part of using Clojure is becoming familiar with the lan

If you really wanted to (and you understand Clojure's destructuring and lambda syntax) you could even do it in two lines: (defn csv-data->maps [[head & lines]] (map #(zipmap head %) lines))

Here is a very simple example that I think does a great job of illustrating how Clojure was designed to deal with "data" in a straight-forward and concise way: (defn csv-data->maps [csv-data] (map zipmap (repeat (
