Git+SVN #4: Collaborate with other Git users

This post is part of a series on Git and Subversion. To see all the related posts, screencasts and other resources, please click here




This one explains some more of the physics of syncing repositories between Git and Subversion land.  The big morale is that you can't really work with branches the way they were made in Git. History will have to be linear by the time you want to push back to Subversion, if you don't want to lose history. This basically requires every merge operation to be a rebase instead.

Theoretically, you could do branches between Git collaborators, but it's probably best to not stay so long out in Git before pushing changes back to Subversion, anyway, so the case for doing any useful branches are basically lost.

You can still do local branching for experimenting with some wild refactoring, or just for sorting different working sets of your code (I do this a lot, in fact). But as long as it's going back to Subversion, it'll have to be straightened up and rebased sooner or later.

Feedback?
This episode is a lot longer than the first ones, almost 15 minutes. I like to keep them shorter, but there was a lot of stuff to go through. I don't spend a huge amount preparing for the recording, and I'm not so interested in spending too much time editing it anyway, so there is some slack in there.

There's a lot of command line action in these videos, so I like going slow and keeping it simple so most viewers can follow what's going on. Do you think the pace is alright? I'd love to hear some more feedback in the comments (preferably here under the blog, not on YouTube).

You can find the first three episodes here.

    Thanks for your effort, it's hugely useful - you saved lots of my typing I'd have done to inform our colleagues.

    A note about this particular post - I feel this a bit wrong:
    "This basically requires every merge operation to be a rebase instead ... you could do branches between Git collaborators, but ... the case for doing any useful branches are basically lost."

    In my experience, you can branch/merge away, share with collaborators - assuming you know the rules of the game.
    The only thing: before dcommit "it'll have to be straightened up" - as you rightly said.. but again that's the last stage, and it doesn't even have to be a rebase (merge --squash comes to mind).

  2. Hi Gin, thanks for your comment! I'm glad to hear these posts can be of some benefit out there :)

    You're absolutely right about the merging. You can save all the "ironing" till last, and squash works well for this purpose, although a little rebase-foo might come in handy (like with the --onto argument).

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

Joining eyeo: A Year in Review

It's been well over a year since I  joined eyeo . And 'tis the season for yearly reviews, so... It's been pretty wild. So many times I thought "this stuff really deserves a bloggin", but then it was too inviting to grab onto the next thing and get that rolling. Instead of taking a deep dive into some topic already, I want to scan through that year in review and think for myself, what were the big things, the important things, the things I achieved, and the things I learned. And then later on, if I ever get around to it, grab one of these topics and elaborate in a dedicated blog-post. Like a bucket-list of the blog posts that I should have written. Here goes: How given no other structures, silos will grow by themselves This was my initial shock after joining the company. Only a few years after taking off as a startup, the hedges began growing, seemingly almost by themselves, and against the will of the founders. I've worked in silos, and in companies wit
