For a dynamic language, it’s more difficult than it needs to be to import a module dynamically in Python. It’s very easy to just from foo import bar, but what if you want to load a list of things and all you have is a string representation of each one, for example foo.bar?
As a company focused on server management, we’ve been talking a lot about how we can help DevOps and IT pros automate tasks and generally make their lives easier. Many a customer have asked us to include scheduling of tasks into our product. So, this past week we just did that!
You can not. This is a lie, just like the cake. You can lower the number of bugs.
The Avail team has announced the first release of Avail, an "articulate programming language," which attempts to offer a somewhat natural expression form for solving programming problems.
ZF2 controllers tend to extend AbstractActionController which does not define a constructor. This means that you can define your own constructor in your controllers and use it to inject the dependencies that your controller needs.
About a year ago I wrote a blog post showing how to stream a HTTP response using Jersey/Jax RS and I recently wanted to do the same thing but this time using JSON.
We’ve all seen industry trends come and go, but DevOps can’t be considered a fad. It’s an approach that has come about as a result of drastic movement in the industry towards automation and the changing role of the IT admin.
Was this OpenSSL vulnerability an oversight by system administrators installing unknown software?
The simple answer is no. OpenSSL is the defacto SSL implementation used on most internet servers around the world. This is not an untested, unverified component that slipped by security audits.
I’ve been using the clj-time library recently – a Clojure wrapper around Joda Time – and one thing I wanted to do is format a date with day suffixes e.g. 1st, 2nd, 3rd.
The Open Session in View (OSIV) pattern gives rise to different opinions in the Java development community. Let's go over OSIV and some of the pros and cons of this pattern.
Shell scripts are a staple in any IT environment. There are quick little scripts for all kinds of little tasks. But, there are also much more complicated scripts to automate critical business processes. If you need to schedule a task or group of tasks, you end up creating a cron job.
I see an interesting parallel in the debate over practices in the running world and practices in the software development world. Indulge me for a moment while I attempt to share my thinking.
Continuous Delivery often challenges conventional wisdom within the IT industry, and by advocating the rapid release of value-add to reduce risk it contradicts the traditional belief that a low release cadence is an effective risk reduction strategy.
At the RSA Conference 2014, we gathered some of the top DevOps experts and influencers at an evening called Wining Not Whining and asked them “Why is application security so important to the DevOps revolution?”
Sirix is a versioning storage system capable of storing and querying snapshots of temporal trees effectively and efficiently. In stark contrast to other database and storage systems Sirix offers advanced versioning at the storage layer and extends high-level APIs as for instance XPath/XQuery.
Below are several development "methodologies" that are popular and even industry-standard
Unless your software is very simple, no single tool or pipeline implementation will provide you with Continuous Delivery. Effective Continuous Delivery requires an organizational understanding of the intent and purposes of the activities you undertake, not merely the automation of those activities.
David H. Hansson (@DHH) sparked the “TDD being dead” latest twitter storm. DHH is no stranger to controversy, and he certainly picked the right title for it. Of course, the responses followed immediately. and most of them fell directly into his...
I guess many people know about the Visitor design pattern, described in the Gang of Four’s Design Patterns: Elements of Reusable Object-Oriented Software book.
I’ve used several version control systems for my source code and research projects. Recently, I’ve consolidated them to TFS and Git. I have started using Visual Studio Online for my research work, CodePlex for my Open Source Frameworks and Tools and GitHub for my blog code.
I'm a vim user and I somehow completely missed this excellent feature until much more recently than I care to admit! Usually vim has its own clipboard, but it doesn't share with the operating system. You will need a vim-gtk install, this isn't available in really basic vim.
Behavior Driven Development (BDD) is an approach that uses conversions around concrete examples to discover, describe and formalize the behavior of a system. BDD tools such as JBehave and Cucumber are often used for writing web-based automated acceptance testing but are also a great fit for other domains such as testing Web Services.
Have you ever come across a situation where testing should be done and you need to rename the class objects? Reveal the secrets of dynamic class generation with the help of Javassist library.
Java has been around for what seems like a very long time, which means that there are a number of ways of scheduling a task
Our topic was originally on scaling self-service of configuration management good practices, but quickly morphed into a discussion of what organizations need to pay attention and foster to support their tools teams in their often-cited mission of creating a self-service culture and self-service infrastructure.
