Learn a New Programming Language Today with Koans - Laura Diane Hamilton
If you're learning a new programming language -- or considering it -- I highly recommend checking out Koans. Essentially, you clone a github repository that has 200 or so failing test cases. Then, you work your way through the test cases, writing functions and filling in the blanks, getting the tests to pass one by one. The first few tests are very basic and assume no prior knowledge of the langua
"Cannot open include file: 'config-win.h': No such file or directory" while installing mysql-python
I'm trying to install mysql-python in a virtualenv using pip on windows. At first, I was getting the same error reported here, but the answer there worked for me too. Now I'm getting this following error: _mysql.c(34) : Fatal error C1083: Cannot open include file: 'config-win.h': No such file or directory If I symlink (Win7) to my regular (not the virtualenv's) python's site-packages/MySQLdb dir I

Getting started with Haskell
I'm going to order this guide by the level of skill you have in Haskell, going from an absolute beginner right up to an expert. Note that this process will take many months (years?), so it is rather long. Absolute Beginner Firstly, Haskell is capable of anything, with enough skill. It is very fast (behind only C and C++ in my experience), and can be used for anything from simulations to servers, g
How to use Scala as a scripting language | alvinalexander.com
This is an excerpt from the Scala Cookbook (partially modified for the internet). This is Recipe 14.10, “How to use Scala as a scripting language.” Problem You want to use Scala as a scripting language on Unix systems, replacing other scripts you’ve written in a Unix shell (Bourne Shell, Bash), Perl, PHP, Ruby, etc. Solution Save your Scala code to a text file, making sure the first three lines of
Optimizing Spark Machine Learning for Small Data - Eugene Zhulenev
Update 2015-10-08: Optimization “hack” described in this post still works, however we don’t use it in production anymore. With careful parallelism config, overhead introduced by distributed models is negligible. You’ve all probably already know how awesome is Spark for doing Machine Learning on Big Data. However I’m pretty sure no one told you how bad (slow) it can be on Small Data. As I mentioned
Scala as a platform for statistical computing and data science
Darren Wilkinson's blog Statistics, computing, functional programming, data science, Bayes, stochastic modelling, systems biology and bioinformatics Menu and widgets There has been a lot of discussion on-line recently about languages for data analysis, statistical computing, and data science more generally. I don’t really want to go into the detail of why I believe that all of the common choices a
Ansible playbook shell output
I would like to quickly monitor some hosts using commands like ps,dstat etc using ansible-playbook. The ansible command itself perfectly does what I want, for instance I'd use: ansible -m shell -a "ps -eo pcpu,user,args | sort -r -k1 | head -n5" and it nicely prints all std output for every host like this: localhost | success | rc=0 >> 0.0 root /sbin/init 0.0 root [kthreadd] 0.0 root [ksoftirqd/0]
GitHub - rerun/rerun: Core rerun. See also http://github.com/rerun-modules
Rerun is a simple framework that turns loose shell scripts into modular automation. Rerun will help you organize your scripts into user friendly commands. Collections of rerun modules can be archived and delivered as a single executable or as RPMs or Debian packages to facilitate handoffs between teams. The included "stubbs" module, helps you develop your own rerun modules, generating option parsi
