Installing ruby 2.0 on Ubuntu 12.04

I wanted to find a way to install ruby 2.0 on Ubuntu 12.04 via Chef, without going the rvm route, which is harder to automate. After several tries, I finally found a list of .deb packages which are necessary and sufficient as pre-requisites. Writing it down here for my future reference, and maybe it will prove useful to others out there.

I downloaded most of these packages from packages.ubuntu.com (if you google their names you'll find them), then I installed them via 'dpkg -i'. Here they are:


libffi5_3.0.9-1_amd64.deb
libssl0.9.8_0.9.8o-7ubuntu3.1_amd64.deb
zlib1g-dev_1.2.3.4.dfsg-3ubuntu4_amd64.deb

The actual ruby .deb package was built with fpm by my colleague Jeff Roberts courtesy of this blog post.

Performance vs. load vs. stress testing

Here's a good interview question for a tester: how do you define performance/load/stress testing? Many times people use these terms interchangeably, but they have in fact quite different meanings. This post is a quick review of these concepts, based on my own experience, but also using definitions from testing literature -- in particular: "Testing computer software" by Kaner et al, "Software testing techniques" by Loveland et al, and "Testing applications on the Web" by Nguyen et al.

Update July 7th, 2005

From the referrer logs I see that this post comes up fairly often in Google searches. I'm updating it with a link to a later post I wrote called 'More on performance vs. load testing'.

Performance testing

The goal of performance testing is not to find bugs, but to eliminate bottlenecks and establish a baseline for future regression testing. To conduct performance testing is to engage in a carefully controlled process of measurement and analys…

Dynamic DNS updates with nsupdate and BIND 9

I first saw nsupdate mentioned on the devops-toolchain mailing list as a tool for dynamically updating DNS zone files from the command line. Since this definitely beats manual editing of zone files, I'd thought I'd give it a try. My setup is BIND 9 on Ubuntu 10.04. I won't go into the details of setting up BIND 9 on Ubuntu -- see a good article about this here.

It took me a while to get nsupdate to work. There are lots of resources out there, but as usual it's hard to separate the grain from the chaff. When everything was said and done, the solution was relatively simple. Here it is.

Generate TSIG keys

# dnssec-keygen -r /dev/urandom -a HMAC-MD5 -b 512 -n HOST myzone.com


This generates 2 files of the form:
-rw-------   1 root bind   122 2012-03-21 15:47 Kmyzone.com.+157+02058.key
-rw-------   1 root bind   229 2012-03-21 15:47 Kmyzone.com.+157+02058.private
Note that I specified /dev/urandom as the source of randomness, which may not meet your security requirements. When I d…

Running Gatling load tests in Docker containers via Jenkins

Image
Gatling is a modern load testing tool written in Scala. As part of the Jenkins setup I am in charge of, I wanted to run load tests using Gatling against a collection of pages for a given website. Here are my notes on how I managed to do this.

Running Gatling as a Docker container locally

There is a Docker image already available on DockerHub, so you can simply pull down the image locally:


$ docker pull denvazh/gatling:2.2.2
Instructions on how to run a container based on this image are available on GitHub:
$ docker run -it --rm -v /home/core/gatling/conf:/opt/gatling/conf \ -v /home/core/gatling/user-files:/opt/gatling/user-files \ -v /home/core/gatling/results:/opt/gatling/results \ denvazh/gatling:2.2.2
Based on these instructions, I created a local directory called gatling, and under it I created 3 sub-directories: conf, results and user-files. I left the conf and results directories empty, and under user-files I created a simulations directory containing a Gatling load test scenario writ…
