Ansible Tower 3.4 Released

January 18th, 2019 Posted by DevOps, News, RedHat No Comment yet

A new version of Ansible Tower has been released, including some useful features we’ve been looking forward to.

In particular the additions to Workflow look very nice:

  • the Workflow Convergence step which allows you to wait on multiple jobs before continuing should simplify some complex logic you’ve had to embed in your workflows to achieve this previously
  • Nested Workflows promises to allow finer-grained modularity and reusability in Workflows
  • Workflow-level inventory, rather than depending on the job template inventory
  • Workflow Always Job Templates, enables job execution of steps regardless of exit status of the workflow.

There is a more detailed write-up over on the Ansible Blog.

 

Website automation with Selenium and JMeter: part 1

December 12th, 2018 Posted by DevOps No Comment yet

This post is part 1 of a series:

One of our customers asked us to troubleshoot their web application: “out of memory” errors were causing page loads to fail. To understand and isolate the problem we needed a way to reproduce it, and observe it in a monitored scenario. We decided on a strategy for both server and web user:

  • Server: deploy a build that monitors for memory leaks, a first-pass step to diagnose the out of memory errors.
  • Client: simulate web requests from one or more users.

It was straightforward to monitor the server application for memory leaks. On the client side we needed a way to generate repeating user requests, potentially at high volume, because the errors didn’t occur for every request. This post describes how we built a client-side process to automate web requests.

Operator Overloading Explained

November 19th, 2018 Posted by Embarcadero 3 comments

In a recent Embarcadero webinar, Marco was demonstrating some new features of Records, including a new Assign operator that can be overloaded.

Afterwards I had a number of questions from people asking what it was all about. Why do we need an Assign operator? Why would you want to overload an operator anyway? After a bit of a discussion with them, I realised that rather than me trying to throw off a couple of sentences to explain it, I should probably write up something clearer.

If you already know what operator overloading for Records is, then this article possibly isn’t for you. But if you’ve seen this mentioned before and not been really sure what it was all about, then hopefully this article will help. (more…)

Public Information on Upcoming RAD Studio 10.3 – Updated!

October 30th, 2018 Posted by Embarcadero, News 1 comment

Over the last week or so Embarcadero has started publicly disclosing more information about the next major release of RAD Studio, Delphi and C++Builder, 10.3.

This is usually a pretty good sign that the release is not far away, so we thought we’d  create a single post with links to all the public information that we have, and keep it updated as more is released.

Back in August, Embarcadero updated their Public Roadmap. (Of course, something appearing on the roadmap is not a guarantee it’ll be released when they planned, but it was the best we had to go on, until recently). Here’s what they said about 10.3 at the time: (more…)

Manage Windows Like Linux with Ansible

Few questions induce fear into the heart of a Linux admin more than, “Hey, can you manage these Windows servers?” In this session, we’ll show how Ansible does simple, secure, and agentless Windows management with the exact same tools, language, and philosophy used for Linux hosts. You’ll never have to log in to a Windows server again. (more…)
