Julian Simpson, aka The Build Doctor, has been working away at a nice web based Build Status Monitor called XFD for a while now. One of my complaints for years has been that there’s no nice build status tool that’s easy to use, but I think he’s on to something.
It’s entered in the Ultimate Wallboard Challenge, and you can vote for it here.
A few years ago Martin Fowler introduced me and a few other ThoughtWorkers who were involved in the Continuous Integration and Deployment space to an editor he knew and told us we needed to write a book about what we were doing. The key thing we were focusing on was making sure that quality software could be released to production in a reliable and repeatable way. Software has absolutely no value until it’s running in production. If you can’t get it into production quickly and easily then you’re just wasting time and money.
There were a few false starts, a few changes of crew, but eventually Jez Humble and Dave Farley stuck it out all the way to the end and Continuous Delivery was published this year. No matter what you do in your organisation, if you’re filled with dread at the thought of a new software release then you need to buy it and read it and do what it says. Now. This article will still be here after you’ve ordered it. Although I didn’t have enough time to be a big contributor, Jez would drag me in front of a white board when ever our paths crossed to discuss things and kept on sending me drafts of key chapters that I have specific interest in and so I am proud to have helped in at least some small way.
One of the things he did do was include a mention to a project that Tom Sulston and I started to make configuration management easier. It’s called ESCape, and I’ve written and talked about it a few times in a few different places. As more and more people are reading the book though I’m getting more questions about what the status of the project is and what our plans are going forward.
At the moment the project is in hibernation. We’ve not made any changes for over a year now, and I don’t think I’ll be working on it in its current incarnation any time soon. That does not mean it’s not based on a good idea though! It’s more a problem of implementation.
At its heart, ESCape is supposed to be a simple way to manage a hierarchal key/value store. I like the way the UI works, Dan North even has a wonderful acronym for it that I can’t for the life of me remember right now. The real problem with the current design is how we’re storing the data. Trying to wedge that kind of data into a relation database always felt dirty and I decided to stop before any real damage was done.
What I’d like to do though is to take the existing UI and functionality and use something like Neo4J or CouchDB to store the data. Conversations I’ve had with Jim Webber and Ian Robinson about it were one of the reasons I didn’t start immediately on a replacement as at the time Jim was making plans to write the REST interface into Neo4J. As an early release of it is now available I guess I’ve run out of excuses…
I’m busy wiring together a new server configuration environment using Windows Deployment Services (don’t ask), Cobbler and Chef. So far things seem to be going quite well, until I bumped in to the following error trying to get a new client to register with the Chef server:
HTTP Request Returned 401 Unauthorized: Failed to authenticate!
A quick sift through Google results didn’t get anything usable. A quick sniff of the packets going over the wire though showed that it was authenticating using a signed certificate. Normally when you sign HTTP requests like that you add some kind of timed expiry. Could the problem be clock related?
Sure enough, a quick check on the new client and the server showed that there was just over an hour time difference. Getting the time on the client and the server in sync got the client registered!
After more than 5 years at ThoughtWorks I’ve decided that it’s time for a change of scenery. As much as I enjoyed the challenge of consulting, meeting new people and seeing new places – I prefer spending time with my family more. It was a tough decision to make, but I think it’s the right one for me now. I will miss many people at TW, but on the plus side I’m again working with some great people who I missed when they left TW…
As I’m going to be doing DevOps type stuff all day every day at DRW now, I’m hoping I’ll have more time to document and share the things I discover.
I’ve been putting off this post for a few months now, but I think the time has finally come to admit what I’m sure people who care have guessed for a while – active development on Buildix has stopped, and will probably not resume. The site will stay up for the foreseeable future, nothing will vanish, but nothing new will be added either.
We started the project because at the time, setting up a new Continuous Integration server was quite an arduous task. The only real option out there for a Java project was CruiseControl, and it could take a new developer days to get their first build through the system. Thankfully though this is no longer the case.
Since then the whole CI landscape has changed. Just having a single “build server” is now more the exception than the rule. It’s all about build farms these days using tools like Cruise, Hudson and TeamCity. They integrate nicely with a variety of SCM’s and story tracking tools. Setting up a build environment with these tools is really easy now. I’d like to think that Buildix at least had something to do with helping people to see how easy it could be to get a CI environment up and running, and I know that at least in the case of Cruise this is true because I’ve been part of that team.
So – thank you to all of you who used Buildix and liked it and provided feedback. Thank you also to the current big players in the CI field who put effort into making sure that looking after your CI environment no longer needs to be a full time job for someone.
A few months ago I got an email from Patrick Debois who I’d met at CITCON Europe asking if I’d be interested in speaking at the first conference aimed at System Administrators practising/interested in/sceptical about Agile. One of the key beliefs of those of us doing this already is that Agile practices are generally too narrowly focussed in their implementation. At the moment it’s primarily the Development organization who drive its adoption, but to get the most benefit Development and Operations groups within an organization need to work together.
With this in mind it was decided to call the conference DevOpsDays. Videos of the talks will be online in the archives section soon, so I’ve decided to write down my thoughts about what went well and not so well – I am a fan of retrospectives.
