Scrumming the night away

Today I decided to do a small experiment.

I was scribbling up a tiny todo-list when I thought "Hey, why don't I do some rough estimation on how long these things will take?". This is what the list looked like at first (at 18:00):
  • Short bike trip - done at 18:30
  • Do some planning for Objectware-uni (training for the new folks) - done at 19:00
  • Fiddle with personal bank-stuff, bills, etc - done at 19:30
  • Write this blog entry - done at 20:00
  • Do some maintenance programming for a customer - done at 22:00
So off I went on my little bike trip, trying out those new bike-shoes that click on to the pedals (did I mention that I cycle to work and I think everybody should do the same?). Naturally, I bumped into my neighbour that I had to help out with moving a fence, and neighbour-chat with for a while. By the time I got back it was 19:20.

Darn. So I had to re-arrange my estimate:
  • Bike and neighbour - done at 19:20
  • Objectware-uni - done at 19:30 (would have to be quick!)
  • Bank business - 20:00
  • Blog - 20:30
  • Programming - 22:00 (1/2 hour less than originally estimated)
On I went to wiki down the uni-plans. Was I quick about it? No. It is very hard to rush stuff that involves thinking. In fact I was so enticed with the state of the wiki that I blew off half-an-hour cleaning and moving stuff around on the wiki. By the end, the time was 20:00. Re-estimating:
  • Bike and neighbour - 19:20
  • Objectware-uni - done at 19:30
  • Wiki-stuff - 20:00
  • Bank - 20:30
  • Blog - 21:00
  • Programming - 22:00 (1 hour less than originally estimated)
[In the moment of writing, it is 21:30, the deadline for my latest blog estimate, so I will have to hurry up now.]

The bank stuff went pretty quick (10 minutes). But then I felt hungry. I eat extremely slow, and I eat a lot (much to the annoyence of fellow lunchers and diners). I made dinner, ate (while reading TheServerSide discussions) and was ready to move on at 21:00.

New estimate:

  • Bike and neighbour - 19:20
  • Objectware-uni - done at 19:30
  • Wiki-stuff - 20:00
  • Bank - 20:30
  • Dinner - 21:00
  • Blog - 21:30
  • Programming - 22:00 (1,5 hours less than originally estimated)
And now my time for blogging is up. Spending a half hour programming doesn't seem very worthwhile, so I'll rather spend the rest of the evening relaxing and planning tomorrows bike-trip to work (lotsa logistics involved there).

Conclusions:
  • Keeping a plan like that made me work more efficiently
  • I quickly discovered things I wouldn't have time for
  • I always discover new tasks I'll have to squeeze into the program
  • I'm easily distracted by these new tasks (will have to work on that)
  • Food takes time and must be planned for (will have to work on that too)
  • Your plan will continously be disturbed by people who want to chat on MSN/IM
Overall, the best thing about Scrum is that it makes you more aware of what you and your team is doing, and what steps can be taken to improve your development process. The next best thing is that it allows you to break estimates and openly admit it without anyone yelling "Sue these guys!"..

  1. You are as crazy and hard working as I know you to be.
    If anyone would put scrum into his personal space it would be you!
    Love your little experiments.

Open source CMS evaluations

I have now seen three more or less serious open source CMS reviews. First guy to hit the field was Matt Raible ( 1 2 3 4 ), ending up with Drupal , Joomla , Magnolia , OpenCms and MeshCMS being runner-ups. Then there is OpenAdvantage that tries out a handful ( Drupal , Exponent CMS , Lenya , Mambo , and Silva ), including Plone which they use for their own site (funny/annoying that the entire site has no RSS-feeds, nor is it possible to comment on the articles), following Matt's approach by exluding many CMS that seem not to fit the criteria. It is somewhat strange that OpenAdvantage cuts away Magnolia because it "Requires J2EE server; difficult to install and configure; more of a framework than CMS", and proceed to include Apache Lenya in the full evaluation. Magnolia does not require a J2EE server. It runs on Tomcat just like Lenya does (maybe it's an idea to bundle Magnolia with Jetty to make it seem more lightweight). I'm still sure that OpenAdvant

Managing dot-files with vcsh and myrepos

Say I want to get my dot-files out on a new computer. Here's what I do: # install vcsh & myrepos via apt/brew/etc vcsh clone https://github.com/tfnico/config-mr.git mr mr update Done! All dot-files are ready to use and in place. No deploy command, no linking up symlinks to the files . No checking/out in my entire home directory as a Git repository. Yet, all my dot-files are neatly kept in fine-grained repositories, and any changes I make are immediately ready to be committed: config-atom.git     -> ~/.atom/* config-mr.git     -> ~/.mrconfig     -> ~/.config/mr/* config-tmuxinator.git       -> ~/.tmuxinator/* config-vim.git     -> ~/.vimrc     -> ~/.vim/* config-bin.git        -> ~/bin/* config-git.git               -> ~/.gitconfig config-tmux.git       -> ~/.tmux.conf     config-zsh.git     -> ~/.zshrc How can this be? The key here is to use vcsh to keep track of your dot-files, and its partner myrepos/mr for o

Leaving eyeo

Thirteen blog posts later, this one notes my departure from eyeo after 4 years and 3 months. I joined eyeo around the headcount of 80 employees, and now I think there's just over 250 people there. My role coming in was as operations manager, doing a mix of infrastructure engineering and technical project management. I later on took on organizational development to help the company deal with its growing pains . We introduced cross-functional teams, departments (kind of like guilds), new leadership structures, goal-setting frameworks, onboarding processes and career frameworks.  And all of this in a rapidly growing distributed company. I'm proud and happy that for a long time I knew every employee by name and got to meet every single new-hire through training them on company structure and processes.  At some point, we had enough experienced leaders and organizational developers that I could zoom back in on working in one team, consulting them on  Git and continuous integration

Using Voice-Chat for Gamers in Distributed Teams

This is a post going into the usefulness of live voice-chat tools in distributed teams. If you've ever seen the Leeeeeroooooyy Jeeeenkiiins video of World of Warcraft fame, you've heard this kind of tool in action. It's how the participants in the video are speaking with each other - this is not a feature built into the World of Warcraft game - it's a separate team-oriented VoIP software, and it's all about letting gamers communicate orally while gaming.  Since these tools are for gamers, they have to be fast (low latency) light (as not to steal CPU-cycles from heavy games graphics)  moderate in bandwidth usage (as not to affect the game server connection) There are several options around: TeamSpeak , Ventrilo , more recently the massively grown Discord , and finally Mumble , which is the open-source alternative of the gang. A few years ago, when I joined eyeo (a distributed company), several of the operations team were avid gamers, and had a TeamSp

Git Stash Blooper (Could not restore untracked files from stash)

The other day I accidentally did a git stash -a , which means it stashes *everything*, including ignored output files (target, build, classes, etc). Ooooops.. What I meant to do was git stash -u , meaning stash modifications plus untracked new files. Anyhows, I ended up with a big fat stash I couldn't get back out. Each time I tried, I got something like this: .../target/temp/dozer.jar already exists, no checkout .../target/temp/core.jar already exists, no checkout .../target/temp/joda-time.jar already exists, no checkout .../target/foo.war already exists, no checkout Could not restore untracked files from stash No matter how I tried checking out different revisions (like the one where I actually made the stash), or using --force, I got the same error. Now these were one of those "keep cool for a second, there's a git way to fix this"situation. I figured: A stash is basically a commit. If we look at my recent commits using   git log --graph --
