Tell someone

Fri, 18 May 2012 21:16:24 +0200

Work remotely sometimes could be annoying, especially when you have a trouble with something and you can’t share it quickly.

This works to me:

1. Record a screencast (I use http://www.techsmith.com/jing.html) and explain your problem to “another person”.

2. Watch the screencast. If you explained your problem wrong, repeat the step 1!!

The 98% of cases I just found a solution by myself. With the other 2%… I share the screencast that I already recorded, :D.

robotmay: Everyone should be using low level caching in Rails

robotmay: Everyone should be using low level caching in Rails:

robotmay:

Low level caching is very easy to get started with in Rails 3, but it seems to be missing from the official guides. I personally use it all the time to help reduce the number of queries or API calls I’m making. Heroku has a pretty good explanation which, if you’re so far unfamiliar with…

Using Sass with sprites

Wed, 09 Nov 2011 13:54:14 +0100

It’s very simple and powerful. Look at this:

Imagine that your single element’s height is 38px; Ok, you can define a variable with this:

$height-element:58px;

Ok, and now you have your background sprite:

.element {
 
        position:absolute;
        bottom:0;
        right:0;
        width:94px;
        background:url(sprite.png) no-repeat 0 0;
        height:$height-element;
      }

And for example 4 elements using this sprite (adding another class):

Inside your .element class:

       &.kind-one {
          background-position:0 0;
        }

        &.kind-two {
          background-position:0 #{-($height-element)};
        }

        &.kind-three {
          background-position:0 #{-($height-element*2)};
        }

        &.kind-four {
          background-position:0 #{-($height-element*3)};
        }

And if you want to add a new element to the sprite or if one of the elements is changed it’s very simple to be used!

Build a powerful Flickr Gallery with Rails and js

Mon, 07 Nov 2011 10:59:00 +0100

If you are using Rails and you need a flickr gallery just bear in mind these two things:

- Flickraw gem
- Galleria plugin

With the first one you need just to add it to your site:

FlickRaw.api_key = 'YOUR_API_KEY'
FlickRaw.shared_secret = 'YOUR_FLICKR_SECRET'
    
flickr = FlickRaw::Flickr.new

And using the complete flickr api, you can use, for example:

@photo_sets = flickr.photosets.getList(:user_id => "USER_ID")

And with Galleria, you could get everything that you want: Ruby code:

<div id="gallery">
    <% @photo_sets.each do |set| %>
      <div id="<%= set.id %>" class="photo_set"></div>
    <% end %>
</div>

Javascript code:

// if you have severals, you can do it with an each loop
var set_id = $('#gallery').children('.photo_set').attr('id');
      
      $('#gallery').children('.photo_set').galleria({
        flickr: 'set:'+set_id,
          flickrOptions: {
            sort: 'date-posted-asc'
          }
      });

P.S.: I wrote a simple example, starting here you can everything that you can imagine, ;)

Setting remotes/origin/HEAD to origin/master

Mon, 07 Nov 2011 10:48:35 +0100

Probably you want to track a new branch locally based on a remote. Just something like:

git branch --track <new-branch> <remote-branch>

Be careful because if you’has selected a remote branch like HEAD, probably you lost the link to master branch. If you want to restart this, you should type:

git remote set-head origin master

Updating ImageMagick with Brew and MacOSX Lion

Sat, 05 Nov 2011 17:13:00 +0100

Upgrade to MacOSX Lion is not perfect. And ImageMagick is not an exception. First of all (obvious), don’t forget to install XCode (or reinstall the C compiler). Following, probably you have tried to download it the binary source but I prefer still using HomeBrew to these kind of things. To do it with this method, just type the next:

cd /usr/local

git reset --hard FETCH_HEAD

brew install imagemagick

That’s all
