Early in 2012, Chris Granger - former Program Manager for Microsoft's Visual Studio product, Bay Area resident, and Clojure enthusiast - released a proof of concept video for something he called "LightTable", a radical rethinking of our traditional programming environments. Over the next few months, new videos appeared, followed by a KickStarter project... ...and gradually the vision of LightTable turned into a series of working software sketches that drew an ever-increasing number of users, taking advan[...]

This release contains minor bug fixes compared to 0.3.0, with the main focus being an overhaul of docstrings etc to improve the auto-gen'd documentation. The community documentation for java.jdbc on clojure-doc has also had a major overhaul. Details of this release: Add nil protocol implementation to ISQLParameter. Improve docstrings and add :arglists for better auto-generated documentation. Make insert-sql private - technically a breaking change but it should never have been public: sorry folks! Provide [...]

I'm very pleased to be able to say that I will be giving a talk on Functional Programming for the Web at both cf.Objective() in May 2014 and Scotch on the Rocks in June 2014! For a little background on the talk, you can read my earlier blog post about Functional Programming for the Web but I wanted to provide a bit more detail about the contents of the talk in this post. If you write web applications in a typical imperative and/or object-oriented language, the logic for each request will generally be a mix[...]

The "gold" release of the Clojure contrib library that wraps JDBC is now available on Maven Central. This release has been in the works for most of this year, as it introduces large changes from the previous "gold" release (0.2.3) that aim to make the library more idiomatic and easier to use in a multi-threaded functional environment. In order to provide a smooth migration path, the old API from the 0.2.3 release has been moved wholesale to the clojure.java.jdbc.deprecated namespace, and the new API in 0.3[...]

Clojure's low-level JDBC wrapper inches closer to a gold 0.3.0 release with the first release candidate. Read more on clojure.java.jdbc's Github repo. The changes in this release are: Deprecate db-transaction (new in 0.3.0) in favor of with-db-transaction JDBC-81. Add with-db-metadata macro and metadata-result function to make it easier to work with SQL metadata JDBC-80. Add with-db-connection macro to make it easier to run groups of operations against a single open connection JDBC-79. Add ISQLValue proto[...]
