This blog post will list out some of the IDE‘s which are used by the Ruby on Rails Developers.
Politics have been with us since the first cave man decided he wanted influence over the next cave man. It’s a reality of human nature that we all want to get ahead and some are willing to do more than others to make that happen.
Earlier this year at ChefConf, rabble-rouser Sascha Bates proclaimed that “training is pointless! Why do training when you can just sequester yourself away and read a book!” But, within earshot were Julian Dunn and Nathen Harvey, who both lead training for a living. This episode, we mediate the 'dispute,' tackling training, learning styles, and industry technical certifications.
When I started my Puppet-ry, the examples I used to see had all configuration data buried inside the DSL code of manifests, people were trying to use inheritance to push down data. Then I got to see a design pattern in puppet manifests keeping out separate parameters manifest for configuration variables.
Recently, I had a chance to write systemd unit files for the daemon processes that run as part of Beaker: beakerd which is the scheduling daemon running on the server and the four daemons running on the lab controller – beaker-proxy, beaker-provision, beaker-watchdog and beaker-transfer.
A high functioning Agile development team is going to be able to new environments casually. Those could be permanent environments, but are more likely to be temporary and for a discrete purpose. A two-week performance measurement project could be one. Why not use a pre-existing environment though?
I use the following statement when I describe the differences between authentication and authorization.
Authentication is finite while Authorization is infinite.
The significant variation is that the latest version has been updated to a modern design with additional features and many simple and user-friendly interfaces. Also, the new Joomla 3.0 has the exciting feature of being mobile friendly and can be specifically used with any modern devices.
There are already many books that get you started with Cucumber, but most of them only teach you the basics or focus on one technology. Cucumber has evolved to a powerful tool though, and today there’s almost no kind of software application that Cucumber can’t test.
I’ve previously come across screen and tmux which allow you to create a session in which you can do some work even if you aren’t currently connected to it which was perfect for my use case. screen was a bit more familiar so I decided to use that and I thought I should make a quick note of some of its basic flags for future me.
Hosting user uploaded files opens a potential attack vector against your website. This post discusses the pitfalls of user content and strategies for dealing with those challenges in Python, Django, and Plone CMS, but the advices applies on all systems.
I have seen many intranets over the years. One thing that always makes me sad is when I see a new intranet launched with a great design, clear structure, interesting content……but no or poor governance.
Following my accident a couple of weeks ago, I’ve now been blessed with a new MacBook Pro which needs setting up again. So, I thought I’d document setting up MySQL, PHP5 and Apache with multiple virtual hosts.
In software development I encounter problems with creating user interfaces for manage logical chains. More complex chain of logic cause more difficult to develop, test, and debug resulting interface. That interfaces are hard to understand without help of man, who participated in the design.
I recently wanted to copy some large files from an AWS instance into an S3 bucket using s3cmd but ended up with the following error when trying to use the ‘put’ command...
Here's a free ebook guide to testing for continuous delivery with Visual Studio 2012.
Packer is a new, open source configuration management tool from Mitchell Hashimoto, creator of Vagrant. Packer aims to automate the creation of any type of machine image for multiple platforms, from a single source configuration.
Are you able to understand 32 lines of Java code in a short time? Let's see. This article explains why understanding Java code is difficult, and how a sophisticated static analyser like 4D Ariadne can help. We have created a short case study on code comprehension to help you compare your skill with that of our developers.
I normally think in terms of Continuous Integration and Continuous Delivery. Where does “Continuous Test” fit in? Paul Duvall, a co-author of the great Continuous Integration book, describes continuous testing as running as many tests as possible with every code change in an article on DeveloperWorks.
"When should I consider moving my project to a Foundation?" Of course the answer is always dependent on the project but I think there are a couple of general scenarios...
Fear and aversion are caused by sheer ignorance. When you gain knowledge on a competing framework, fear can turn in two directions.
If you ask most developers, they will tell you that working in maintenance sucks. Understanding and fixing somebody else’s lousy code is hard. It’s tedious. And it’s frustrating – because you know you would do a better job if you were given the chance to do it over and do it right.
Did the test fail due to an application bug or is it the environment? Once again, the dreaded chant of “it works locally” is taken up. What most people fail to understand is that the failing test is the first sign of a communication breakdown between developers and sysadmins.
Even if you think you’ve done a good job of explaining something, the receiver of the communication decides whether or not that’s the case.
