• AnsibleFest London 2016

    21 Feb 2016

    This year I attended AnsibleFest in London. I have been using Ansible extensively at work and a combination of very interesting talks, being somewhat nearby (read, not across an ocean) and not having a super expensive ticket price made it so that I could go. The conference itself started early in the morning and happened in a hotel very near the O2 Arena. It had a kind of lobby with about ~5 sponsor booths, and one very large conference room with a low stage.

  • 2015 in review

    09 Jan 2016

    In December I decided that starting to write year in review posts each year would be a cool way to look back and check how productive I was during the year, and if I manage to do this for more than a year it’ll at least be fun to get a local perspective on the past when I’m older. The thing is that writing this in December seemed wrong so I left it to January, and then put it off without any reason. Anyway, let’s do this.

  • Pull requests without the messy commit history

    17 Oct 2015

    So you’re using some kind of configuration management system and you use a pull based deploy method where nodes pull configuration and set themselves up. Whenever you make changes to these configuration files you’re probably committing those changes and pushing them to the place where you keep these files so that you can test if your changes don’t break the machines. You’re probably doing this in a feature branch and eventually stuff will break, stuff will un-break and every time you’re committing and polluting this feature branch. When you’re done and want to merge things into master you’re going to have a pull request with a bunch of commits that are just experiments along the way. Now there’s a couple of reasons why having too many useless commits in a pull request aren’t ideal but the best one is that reviewers and yourself will have a much harder time understanding changes because the really useful commits might be hidden among the bug fixes and experiments. Let’s see how to prevent it.

  • The twelve networking rules

    15 Jan 2015

    A Request for Comments (RFC) is a publication of the Internet Engineering Task Force (IETF) and the Internet Society, the principal technical development and standards-setting bodies for the Internet. An RFC is authored by engineers and computer scientists in the form of a memorandum describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems. It is submitted either for peer review or simply to convey new concepts, information, or (occasionally) engineering humor. The IETF adopts some of the proposals published as RFCs as Internet standards.
