The Deployment Elephant

Tim O’Reilly covers much of what’s been crossing my mind recently in Operations: The New Secret Sauce. The really successful people are those who (like Google) have solved, and are continuing to solve the really hard problem of deployment. There is a huge gulf between programmers and sysadmins that needs to be crossed so you can get software that works really well. It’s all very well writing code that works “great on my PC”, but when you have to stick it on a Unix server blows up (reminds me of the “Best Viewed On My Monitor” graphics that festooned the web a few years back). We can and must do better.

Part of the problem is that nobody is seriously talking about deployment. During our company’s recent move towards Java, I’ve found it seriously hard to work out what best practises are and have already gone through several painful experiences working things out. Yes, this is part of the normal learning curve. But it would have been really, really nice to look them up in a “Deployment Patterns” book.

Update: on a tangentially related note, Steve Loughran notes:

There is a very simple test to see if the deployment process is working. If you have to go into the air-conditioned server room on a weekend or on your vacation, deployment is broken. If you are scared of the mobile phone ringing, because it may be the operations team, deployment is broken. If you are a week away from going live and you haven’t started bringing up the server, then the process is broken, you just don’t know it yet


The Treason Show

I went to see The Treason Show last Friday night. It’s about the fourth time I’ve been and I’m still being entertained. Song and dance satire can’t be beat.

However, I do have a couple of complaints:

  • Too much football. Really. I hate football, despise the world crap and really want to go out and get away from it. Having said that, the finale of “We’re not the champions” was beautifully done.
  • Tables. This is more aimed at Komedia rather than the show. But all the tables were a) really tightly packed in and b) reserved anyway. We got there fairly soon after it opened and there were no free tables (they were empty, just unavailable). Instead, we got to sit on the very uncomfortable stools for the whole show. They really need to rethink this.

Overall though, still very enjoyable, despite the extremely loud and pissed woman two tables down.



A few days ago, somebody at work showed me LibraryThing. It’s the application I’d always wanted to build myself for managing my books. And now somebody’s done it for me. I’ve now chucked all my computer books in and they’re available at: By which you can safely conclude that I have spent too much money on books over the years.

The main downside to LibraryThing that I experienced was incredible slowness at times. However today, the message is up that it’s moving on to new servers. So hopefully a speedier experience is ahead!
