A little more open source: a personal accounting software

Today I published on GitHub a software I developed for personal accounting I use for a long time. It may help some of you with custom view, table views and probably Core Data, or provide a fundation if you want to build such software. It’s available on GitHub ! Enjoy 😉

nginx reverse-proxying unicorn

After the experiments detailed in my last post, I faced today the need to have clean ruby/gems environments for each project I deploy on my Amazon EC2 server. Just like on my development machine, I wish to use <code>rvm</code> to make a separate gemset for each application.

However, to be able to run each app in its own environment, using a dedicated ruby-server instance is needed. Like described in my previous post, I was using Passenger to do that. Trying to deploy a ruby-1.9.2 / rails 3.1 app, I could not get Passenger Standalone installed due to some rake > 0.9.0 incompatibilities. This required to get the last version of the Passenger gem on GitHub, what I can’t do with my current knowledge.

Since I was using Passenger to make deployment easier, I was wondering if it was still the case. And I was feeling like it was getting a very big machine running for each app, while there was surely other solutions. And sure there is! There are other ruby production-class servers which can be used: Thin, Unicorn, and surely many others. And since I’m reverse-proxying through nginx, I can use any of them.

So, from now, I’ll be using Unicorn. It’s much more easy to get it running, no need to have a complex and hazardous installation process, just add it to the Gemfile, bundle install and get it running. I think it will do the trick for now.

Reunionite is now opensource on GitHub if you need some material to start building an iPhone app!

Find it there: https://github.com/rchampourlier/Reunionite

More info on the app here! And you can get it on the AppStore too…

Feel free to contact me if you need some info, I was in a hurry when developing so there is not much documentation 😦

nginx + Rails (through Passenger) on different Rubies + PHP, all this on Amazon AWS

Hi everybody!

It’s been quite a long time since my last post… I have lots to do, I’m working on a startup project and I’ve now another blog on which I have to write. I do not spend so much time developing, and almost not any more for Cocoa…

Due to my project I’ve been switching to web application technologies, and since I’m looking in the startup ecosystem, I’ve been looking at Ruby On Rails. After having played a little with Heroku, I wanted to start with a more customized hosting experience, so I’m now testing Amazon AWS service, through their free 1-year tier (allowing a sufficient cloud hosting for my purpose).

However, since I found the road quite long to reach a working config (I’m really newbie as sysadmin), I put all the things I went through on an Evernote page, and now I’m sharing them with you. It’s raw, I’ll try to refine all this with the time, but it may help nonetheless. And feel free to ask for help, I’ll do what I can 😉

A great article to have a better understanding of Javascript’s prototype

The concept of prototype, the variables involved, the meaning depending on the browser and the use in inheritance: a great article, clarifying the thing out in a nice way!

Snow Leopard, 64bits, Ruby and MySQL

I recently started again wanting to play a little bit with the so acclaimed Ruby on Rails framework. Being on a Mac, I had not much to do to start working, with Ruby & RoR already installed with my Snow Leopard default OS X install (maybe because I’ve already installed the XCode Developer package, as well as the iPhone’s one… maybe you should check). So I was playing with my Ruby on Rails’ guide and I had already started building a project, having it displayed in my browser, so I knew the core of the install was up and ready.

Next step was to connect with MySQL. It proved not to be so simple as expected… Running rake db:migrate to check Ruby was well connected with MySQL lead to the following errors (both errors came repeatedly during my way to the solution, given below…):

  • uninitialized constant MysqlCompat::MysqlRes
  • dyld: lazy symbol binding failed: Symbol not found: _mysql_init
    Referenced from: /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/
    mysql.bundle

After some research and tests following different articles on the net, I finally got with a working solution (however please notice that it applies to an Intel Mac with 64bits processor under Snow Leopard):

  • Install the latest x86_64 MySQL release (currently the mysql-5.1.53-osx10.6-x86_64). Several articles on the net will tell you the problems are due to the 64 bits version, you should install the 32 bits one, and so on. In my case, I tried both and it worked with the 64 bits one.
  • Make it work! Check the install documentation, connect with mysql, start the server… to be sure everything is working. A good thing would be to be able to connect to it with phpMyAdmin for example (which I did).
  • If you had already install the mysql gem (which you should have to need this page because you must have faced the previously mentioned issues…), uninstall it with sudo gem uninstall mysql.
  • The trick is then to reinstall it with the following command line: sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config which ensures the gem is installed for the 64bits architecture, matching the MySQL one.

Then, you should not face the previous problem any more, maybe some access denials due to misconfiguration in your RoR’s project “database.yml” file or your MySQL configuration. But the Ruby/MySQL connection should be OK!
