No more “bundle exec …” - my gem solving this integration problem for rubygems and bundler is almost ready to be released, I'm sharing information what is inside, what it does and some future plans for it.

There is so much confusion around deploying applications using RVM, I went down and verified. The process was quite straight forward, but I found few points that could be improved. My goal was to be able to install rails app on server without complicated recipes and doing much on server. All my experiments were done using fresh rails app with one model, you can find sources here ...

About half year ago I have written a gem to eliminate the need of using bundle exec – rubygems-bundler. Today I have released a bundler gem fork of the latest version 1.0.21 – mpapis-bundler, including support for rubygems plugins and adding dependency to rubygems-bundler. Anyone tired of writing bundle exec can now easily avoid it by using mpapis-bundler instead of bundler. ...

Ever used grep and wanted to check that file with less? Now it is easy with wrapping functions, they parse grep outputted lines.

I just released rubygems-bundler integration gem version 0.2.1 - no more calling 'bundler install --binstubs' or 'bundler exec ...'. Install it by calling 'gem install rubygems-bundler' and follow the on-screen instructions. Current version 0.2.1 includes ported custom_shebang from rubygems 1.9, now you can start using it before it is released. rubygems-bundler works fine with ruby 1.8.7 & 1.9.2, it works with rubygems 1.3.7, 1.5.0, 1.6.2 & 1.8.5 ... it should be also working with 1.9.0 when it will be released. Note: This gem allows to use binaries in version specified by Gemfile ;)

Searching for new experiences I have tried a new setup - passenger standalone on rvm monitored by god and cron (see Q&A on the end). ... please note that cucumber is only required when you use it, skip this param if cucumber is only an tasty vegetable for you.

Over a year ago I have posted instruction how to setup simple git server, today I had to do it again but already having code so here is new instruction...

So here is script, it is almost simple, find some processes, and kill them if to much RAM .... Most important in this script are first two variables, threshold_mb which is a limit for showing processes (it is rough comparison) and kill_at_mb which is limit for killing processes, by default this limit is 5 times bigger then showing threshold. Cause killing is more important operation additional check for used memory is more strict to be sure, only processes over the limit are killed...

Very simple yet powerful library for rendering data (JSON) on html using jquery selectors matching.

As a proof of concept I created an super action that allows to process more than one action at once. Probably most of you will ask a question ‘why’ if there is an posibility to use nested resources. Yes you can, but what if there are more different actions that do not have common root?

After long playing around with my prompt I finally made it stable and thought it’s time to share :)

Some time ago I wrote about complex associations http://niczsoft.com/2010/01/complex-associations-in-rails-activerecord/, now time to add another method and corrections.

Working on my new app I thought it is necessary to get some data from configuration file, there was already plugin that had the necessary functionality - acts_as_configurable. Unfortunately this plugin was not exactly what I was looking for It had possibility to write configuration in the class itself - I needed configuration in file. So I did fork of the project, and now you have possibility to use rewritten version of the plugin which uses yaml file for storing configuration.

Lately I’m using quite often very similar path for work with git, to not loose it with time, and of course to return my few bits to community I put my links here. So my path of usage is 1. Setting up private git repository - I use my own server for trial projects, instructions for windows/github follow bellow, 2. Pushing & Pulling sources with remote git server - my instruction covers cloning remote repo but not connecting it with working sources, this instruction seams to cover it quite good, 3. How to use git the right way ...

Most of standard testing related tasks can be achieved in a simple way using the default steps from Cucumber. By assumption Cucumber is for functional testing, but it can also be used to implement integration test. This is especially useful when we want test interaction between users, when they should get on-line notifications - and this should be tested without login/logout functionality, like in shout box which was popular some time ago.

I have seen a lot of migrations, most of them was just doing what it had to do. But I found a nice way to make my migrations more pretty. So I had an Article model, which had field :published of type :boolean , as comparing to other solutions, I found that it should be rather :publish_date of type date. First I have created migration using “script/generate migration article_update” and got empty migration:

As things look quite straight there were few gotchas which make the task spread to few hours, but finally I succeded and the result is already published at Trac-Hacks.org - DepgraphSidebarPlugin

Did you ever dreamed of you own distribution, I know some of you did like me. Now this becomes easily accessible to everybody with some knowledge what he wants. Returning to theme of the article while searching for opensuse 11.2 and kde 3.5 I found worth trying one of novel services: http://susestudio.com So gathering information from around the web and my previous trials of this configuration I did added plenty of repositories, my favorite packages to my new appliance … after some tries I was able to finally build my distribution, that’s quite orginall that I could build whole distro without using anything else then my browser. But guess how I was surprised when under my fresh build distro I found link testdrive - I dont need anything then browser not only to create an distro, I can also test it within browser.
