Julia, the One Programming Language to Rule Them All
After all the Julia hype on HN I thought I'd try it out.I was surprised to discover how slow it actually is to use.  Here's a quick demo of booting up the Julia repl with two libraries loaded and then immediately exiting:    $ time julia -e 'using Distributions; using Gadfly; exit()'

With behavior like that it's not going to replace R as my go-to tool for graphically exploring data.I'm sure they'll improve this eventually.  Much like with Rust, my hopes are high.  But also much like with Rust, I wish the hype came after the promises were met.PS: this article claims that Julia 1.0 was released in 2012, but as best as I can tell the most recent code you can get calls itself 0.3.  The above was with Version 0.3.0-prerelease+1174 (2014-01-23 16:58 UTC).
