About I strongly believe that ignorance is one of the most powerful tools we should employ when we build software. As a mechanism to enforce de-coupling it is great. What?! Huh?! No, I haven’t lost the plot (any more than usual), I simply mean that I strive to build small components that are as ignorant as possible. ... Read more

Another quick tip. I use the excellent cljsbuild to compile and test our ClojureScript projects (and I can’t believe how difficult it is to wire this stuff together in 2016!). To support continuous integration I use phantomjs to provide the JavaScript environment. Unfortunately circleci’s environment doesn’t have phantomjs v2 available to it and v1 has some troubling properties. It turns out, after much googling and dead ends, that it is pretty trivial to get phantomjs in your circleci environment, simply add: ... Read more

Similarly, if an Exception is raised server side it is also pushed to the error-handler. However, the errors that had been captured were all ridiculously long stack traces with no references to any of my code. ... Read more
