Re: [ANN] Clojure 1.8.0-RC1 is now available

Hi, I ran Yeller's very extensive benchmark suite against Clojure 1.8 RC1. I saw no performance regressions, over 72 individual benchmarks. There were no notable performance improvements either (all benchmarks were comparatively equal to a benchmark run against 1.7 with a 95% confidence interval)

[ANN]: Matcha, a library for composable test assertions with human readable error messages

Matcha lets you write flexible, composable test assertions with human friendly error messages. It's modeled after the excellent Java Hamcrest library. As a quick example, you might build up a matcher that says "this map has 5 elements, and the :foo key must be greater than 10" like so: ``` (re

Re: JDK8

Java 7 is EOL as of last week, so pretty much everybody who runs stuff in production should be upgrading to Java 8 unless they have a support contract that lets them do otherwise. There won't be (as far as I know) more security updates/etc on the Java 7 line any more. Yeller's (http://yellerapp

[ANN] Bolth: a humane, parallelized test runner for clojure.test

Hi there, I've written a new test runner for clojure.test. It does 2 main new things: parallelization, and *much* better output, error reporting, and some surrounding formatting/running features. All the features were extracted from stuff I've accumulated in my app's user namespace over the la

Re: [ANN] Clojure 1.7.0-alpha6 released

Yeller (yellerapp.com) (which I maintain) has a comprehensive benchmark suite (using criterium, with a heck of a lot of work put into getting real and good results). I've run Yeller's benchmark suite against clojure 1.7 alpha6 - it's pretty comprehensive, and covers a wide range of things. Resul

Re: Kwargs vs explicit parameter map for APIs?

Hi there, I feel pretty strongly about this - I *much* prefer using APIs with explicit options maps. The community is pretty divided though. I wrote up the tradeoffs (which are well discussed here as well), as well as a list of libraries using each style: http://yellerapp.com/posts/2015-03-22-

ANN: Clojure-Miniprofiler, a web application profiling tool

Clojure Miniprofiler is a simple, but effective profiling tool for your web application. It tells you what is slow about a web page both in production (for admins only), and in development, as you load the page. It's a port of the original .Net library to Clojure, utilizing the JavaScript and

Re: [ANN] Clojure 1.7.0-alpha5 now available

I said this already on twitter, but I see heavy (5-10x slower) perf regressions on my benchmark suite from 1.7-alpha5 vs 1.6. I am trying the other alphas now - I have a comprehensive benchmark suite that takes 4 hours or so to run, and it's a bit backed up right now (I only have one box to run

Carlo, Nice! I wrote a sketch of this idea the day after I watched the talk: https://github.com/tcrayford/laundromat, but never pursued it much further (though I do use it in my test suite). Awesome to see some real work put into this idea. On Friday, 28 November 2014 00:44:16 UTC, Carlo

Hi Andy, All, I wrote a tool like this: https://github.com/tcrayford/laundromat it's super hacky, and the api is definitely in beta. I asked some folk about reviewing this api, got little feedback, and figured it wasn't that much of a wanted thing after all. I still use it internally

Re: [PSA] Clojars scp disabled until further notice

Phil, I've used scp uploads in the past. They're much easier when e.g. you wanna upload a java library you've forked. Without scp uploads (or an easy copy/paste curl alternative), you have to go through getting the project to build with lein by itself. It's not *too* difficult to get a maven ba

I like YourKit. It's commercial, but really quite good (free for open source if you promote them in your readme). I wrote a bit about the perf wins I got using yourkit on my app here: http://yellerapp.com/posts/2014-05-21-tuning-clojure-an-experience-report.html On Friday, 20 June 2014 14:05:0
