Installing Ruby and Rails on Ubuntu 12.10 can throw up some errors. I’ve found a method that worked, and wrote a few notes about it.
A must read for new Linux system administrator and anyone from the development side responsible for keeping a Linux server running.
More and more frequently I’m seeing cool use cases of Log data. Using ‘logs as data’ is the concept of writing semi-structured data to your logs which can then in turn be consumed by other services that can put the data to good use.
There was a PLOG2013 symposium in spring 2013, for developers and alike. It was organized by Abstract IT in Italy, on the coast of Mediterranean, in the city of Sorrento.
Although I didn’t go to Dev Ops Days London earlier in the year I was following the hash tag on twitter and one of my favourites things that I read was the following: “Treating servers as cattle, not as pets.”
Ruby 2.0 was released on 24th February to coincide with Ruby’s 20th anniversary. If you use RVM, and want to try out Rails 4.0 beta, then ideally you’ll want to be running Ruby 2.0. Here’s what I did to keep my development environment working the way I like it.
jenv is a tool for managing parallel versions of Java Development Kits on any Unix-based system.
I love the idea of DevOps, especially when it means I can dev something for my Ops team.
Below are my slides for the presentation held in PLOG2013Plone symposium. It’s about good software development documentation culture, writing documentation for Python packages and maintaining up-to-date developer documentation in Plone ecosystem.
Here's a short example of the usage of the Google Viewer and Google Docs embeds (see here). If you want to embed a view of any file on Google Drive/Docs you can do this by putting a pdf preview (the file could be in any format, see first example, which is a Google text document) in an iframe or, in the case of spreadsheets, the speradsheet itself into an iframe.
I’ve been spending a lot of time recently thinking about ways of orchestrating long running workflows in a service oriented architecture.
This article shows a hands-on approach of how you can test your IBM WebSphere Message Broker solutions in a simple way using modern Groovy and Java tools.
There are DevOps tools and DevOps job ads. People talk about culture and sharing and being nice to each other. Sounds pretty fishy, right? The only thing missing is a DevOps certification and we’re done with the DevOps hype. Is DevOps really just a fad? Let’s take a closer look…
If you’re trying to convince yourself (or the team or management) that your operations program needs to be changed for the better, and that trying a DevOps approach makes sense – or that your operations organization is improving, and that whatever changes you have made actually make a difference – you have to measure something(s). But what?
When you have got multiple versions of Java installed, you can choose which one you want to use by running the update-alternatives command.
UrbanCode CEO and co-founder, Maciej Zawadzki, explains that Continuous Integration is more than just merging code. Join him as he explains some of the fundamentals of Continuous Integration in the third installment of the uChat video series.
I've already examined how important good testing is to the health of a project, a product and an organization. There’s a lot more to good testing than running an automated test suite in Continuous Integration and forcing someone to walk through functional test scripts and check lists.
HTTPS or SSL or TLS or whatever you want to call it can be a confusing beast. Some say it’s just about protecting your password and banking info whilst the packets are flying around the web but I’ve long said that SSL is not about encryption.
Certainly I’m not the first to notice the similarity between Test Driven Development and the Scientific Method?
Today: A new fork of WebKit from Google, a big security update for Postgres, new releases for R and Rust, and some very exciting positrons.
Imagine waking up to find your site and service hacked. Everyone is running around, trying to find out what went wrong; you’re tasked with repairing the damage. But unfortunately, that automation project you’ve been promising yourself you’d get done has always taken a backburner to more pressing matters and features.
Despite the fact that I’ve been working full time in software for almost 8 years now every now and then I still need a reminder of how useful reading logs can be in helping solve problems.
Today is a great day. Everyone is now aware of the problem and truly believes that technical debt affects the velocity of teams. But when facing this mountain of technical debt that covers every single wall with post-its, many development teams renounce to continue code quality remediation projects. See in this post how to set a Dynamic Violation Filtering in Eclipse to progressively show code violations.
WANdisco submitted Bloodhound to the Apache Incubator in December 2011 and our developers have been involved in the Apache Bloodhound project since its inception. So we’re pleased that today the Apache Software Foundation (ASF) officially announced Bloodhound as a Top-Level Project (TLP).
A simple and elegant way of constructing immutable Java classes, using hints in the parameter list.
