From SVN to Gitlab on RHEL6

Edit: This howto isn’t finished. I was able to import SVN but didn’t get the repository to appear in Gitlab.

There is a certain SVN project that i’ve moved to gitlab over the weekend. It started with installing the RHEL6 environment, moving all the revisions there with gitlab and then setting up svn-git.



Since it was the first time I was installing gitlab, I looked online for a howto guide. I stumbled upon the automatic script by mattias-ohlsson which didn’t work so well for me. The automated script kept returning error messages regarding an outdated ruby version, which my sudo user indeed was having. I didn’t want to wrap my head around that misery and instead made use of these directions made by Torey Maerz. I didn’t run the script automatically but triggered each command manually. Some notes:

At one point whilst compiling the bundles for gitlabhq, I got into trouble because I had no pg_config, instead installed postgresql-devel.x86_64 and after that the package compiled correctly.

Then passenger came with the directives:

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p448/gems/passenger-4.0.10/buildout/apache2/
PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-p448/gems/passenger-4.0.10
PassengerDefaultRuby /usr/local/rvm/wrappers/ruby-1.9.3-p448/ruby

So I put these in my httpd server, together with the directive to turn se_linux off. Yes naughty.
setenforce 0

and then setup my virtual host as follows. Be sure to use a real domainname, as I had trouble getting gitlab to work on an IP.

<VirtualHost *:4000>
  ServerName <domainname.tld>
  # !!! Be sure to point DocumentRoot to 'public'!
  DocumentRoot /var/www/gitlabhq/public
  <Directory /var/www/gitlabhq/public>
     # This relaxes Apache security settings.
     AllowOverride all
     # MultiViews must be turned off.
     Options -MultiViews

Now we adjust the username and password, be sure to do so. That ‘5iveL!fe’ password is floating all over the internet.


Login to the RHEL6 machine and import the svn-git:
install svn-git
yum install ruby rubygems
gem install svn2git

Next is the svn2git import. The followin command was rambling for about 6 hours for a 10 Gb repository. I’d recommend executing the svn2git command with the ‘time’ flag. I also had to ‘nohup’ the command to safely execute on my wifi connection.

time svn2git http://<domain><reponame>  -v --username joop

If you run into an error “the variable $u was not defined“, don’t worry I solved mine with this this fix. It seems like a harmless patch.

Then you can import your project into gitlab using:
1. Copy bare repositories to /home/git/repositories
2. Run bundle exec rake gitlab:import:repos RAILS_ENV=production

Celebrating summer

Due to Suna’s business trip in the UK, I’ve decided to have some time off with friends. So we organized a ‘back to basic’ evening where we would camp outside. It was fun setting up the camp, go for a swim and build a fire to prepare food on. We chatted away into the evening and I was so tired I slept very deeply. The next morning I woke up by the sound of birds and a ship that was passing by. Even though of all the trouble, I was very relaxed from the camping experience!

We took it easy in the morning and headed back, actually just in time because a huge thunderstorm broke loose as soon as we came home. We enjoyed this summer storm with a coffee at the shack in the backyard. When my friends left I went to see a football match in Amsterdam with my family; the first half was quite boring so I nearly fell asleep but the second half was very exciting!

Chinese Brands Climbing the Curve

Roughly a decade ago, Stan Shih, chairman of the Taiwan-based Acer Inc. coined the term ‘Smiling curve’, which pointed out that Chinese manufacturing added little value. They lacked the high value steps of the production chain, like R&D and marketing.

When I read this for the first time, I asked Twitter to list three influential Chinese brands. No satisfying reply: LG? (Korean) HTC? (Taiwanese)? It made me painfully clear that Chinese brands had a long way to go.

These days I’m back in The Netherlands and it’s somewhat a different world. Innovation aside, it seems that Chinese brands are entering the European households. I noticed a banner for a Chinese bank at the airport. My sports team is sponsored by a Chinese company.

And as mentioned before, these days the phrase “You should not worry about China making cheaper products, you should worry about China making better products”. comes to mind. No wonder Apple is opening an R&D center in Shanghai.

Reading that, I went online and asked the same question from five years before, the first European reply included: Alibaba, China Mobile, Huawei.

Seems that China is getting successful at climbing the curves of the smile.

Living Outside Asia, Customer Service and Transportation

A recurring theme in our household; comparing our life in east Asia to that here in Europe. I know we shouldn’t generalize because people live in bubbles but we can’t help it. The topic goes back a few years, when talking to a Korean friend at a Daejeon bar in 2008, we ordered beer with one of those remote tokens with buttons (beer/bill etc) that are common every where these days. He was surprised these weren’t common yet in the, what he called developed world. (even though South Korea is
developed, it arrived at such standards much much later) He was surprised that I praised the technology in Korea. He expected all of that would be more than common. It wasn’t.

So while a developed country might seem more comfortable, and there are lot’s and lot’s of perks, some things just haven’t arrived yet; Traveling back and forth to Korea can feel like a time travel. That feeling is probably due to the little things; Opening doors with keypads, watching TV in the metro, faster trains etc etc.

Second recurring theme is that of customer service. Chinese customers are raising the bar for service expectations as competition is fierce. Our feeling in The Netherlands is that customers simply don’t expect high customer service.

I’ve asked some friends from Asia that moved to Europe and North America. A Chinese replied on Weibo:

Life quality here is definitely better than in China. Air quality, food quality and so on. But because the smaller population, it’s not very convenient. Especially public transportation. The subway has only two main lines in this city and the taxi’s are too expensive. Most people living downtown have to buy a car.

Talking to them, the recurring theme seemed to be: Transportation. On the food part, friends were divided. Chinese seem to be able to get their foods abroad and thought food quality improved. Korean and Taiwanese friends seem to miss their home food (fruit!) a lot.

In the end, if you have a choice… one should just be happy where he/she resides I suppose. There are pro’s and con’s at every corner of the earth.

Vagrant Up

Somewhat smarter working method for web developers: When building projects, work inside virtual boxes instead on your workstation directly. Why? Each project has it’s own characteristics and software dependancies. Each programmer added on the project has to spent time configuring his or her workstation to your project.

Does the following sound familiar?

We work with OSX so you better bring a mac. No, your are running 5.3, our project is build for PHP 5.4. You need to set the following env variables. Allow .htaccess. Oh, why don’t you have Git? And GD? etc etc.

You know what I mean right? Meet vagrant.

Interpreting the guide below and my brief experiement this morning, Vagrant allows quick starting (and sharing) of Virtualization boxes on workstations. A new employee enters the project, receives a laptop with instructions on how to pull the right vagrant/puppet setup, types ‘vagrant up’ and has a Linux distro of our choice with the right software installed due to chef firing up.

If this triggers your interest, I followed the instructions by ShawnMcCool on Github this morning and already moved one project inside the box. I’m going to experiment a bit more before I move all projects.

Quick Glance at I3 Window Manager

I have been using the i3 window management over the weekend.

Now, what is i3? i3 is a tiling window manager created by Michael Stapelberg. Tiling means that instead of the floating windows on your conventional windows or mac desktop, windows are presented in tiles.

I just happened to pass by it and got intrigued. Working a lot in terminal emulators, I sometimes wondered what the desktop experience could be without all the clutter and the heavy use of mouse gestures. A tiled desktop essentially means that your applications are always visible and you have a clear overview. Applications will not hide behind each other but are displayed next to each other. Furthermore, there is no desktop. when you add a window, it’s added and your
screensize is reduced, unless you select a stacking mode.

I watched a presentation of Michael and he explained that the tile based window manager isn’t new. There was one before called ‘window manager improved’, then followed ‘windown manager improved improved’ and thus the name of his version became ‘i3’.

After playing with it for some time, I decided that I’ll keep it for some time longer. However, at work I still use OSX.

Thinking about all those OS’es reminds of a quote by David Field:

The thing about an Operating System is, you spend a huge amount of time invested with it, be it on your Mobile or Desktop its a very personal experience. You put your choice of apps, and your data on it, and spend most of your day using one, in some cases you probably spend more time with your OS than the people you care about. Its a personal choice you’ve invested in, one which is you’re tool of choice.

In the end it’s about picking the tool to do the job. Seeing a different approach to a method we’ve all be aquanted to is a fresh breeze. I can’t wait to work with it some more.

The Big 30

This week will mark my 30th birthday; Since it’s a round number it sounds like a milestone. Wowzers: 30 years… Old for some, young for others.

Octopress Update

Octopress is a highly customizable blogpost generator. Posts are written and stored in Markdown and Octopress allows easy Jekyll distribution as HTML through S3 or Github. If you use Octopress, I recommend following ’Making Octopress Fast’ written by Eric Wendelin. The guide will help you setup a GZipped website on Amazon S3. It worked like a charm but I lost two important elements: Previewing and quick deploys.


After following the guide, all HTML/CSS and JS files are stored as GZip-9 files. Unreadable unless you add a ‘Content-Encoding gzip’ to the header of each file and enable a deflate mechanic to your local webserver. Besides, Jekyll is shipped with a preview WEBrick server which is rendered useless.

Solution: Preview from the public folder and add a second directory for compression.

I’ve added a referral to a compressed directory. Then make sure that all directives for minifying and combining read from #{public_dir} and that all zipping is delayed until after task tocompressed is invoked.

desc "Copying public contents to compressed folder"
task :tocompressed do
   puts "## Copying to compressed directory"
   puts "\n## copying #{public_dir} to #{compressed_dir}"
          cp_r "#{public_dir}/.", "#{compressed_dir}"
                 cd "#{compressed_dir}"

Adding an extra directory to the process results in a public folder which can be previewed. Deployment is done from compressed_dir.

Iterative deploys

Here is the problem I was experiencing. Deploys became long and dreadful after adding GZip to the deployment process. The s3cmd tool allows incremental uploading but since I started GZipping the files, s3cmd seems to just upload everything. At first I thought this might be because I was adding ‘Content encoding’ headers to the files I was deploying. Then I wondered if I could get around it with the ’ –skip-existing ’ parameter to the s3cmd command.

Solution: The problem was
caused by GZip leaving a timestamp inside the zip file. This was solved by adding the -n parameter to the gzip commando.

desc "GZip HTML"
task :gzip_html do
puts "##GZipping HTML"
  system 'find compressed/ -type f -name \*.html -exec gzip -9 -n {} \;'
     Dir['**/*.html.gz'].each do |f| test(?f, f) and File.rename(f, f.gsub(/\.html\.gz/, '.html'))

I still find myself evaluating the Octopress environment but it seems highly customizable so what’s not to love?
