I’m posting this entry because I felt like I didn’t give enough love to the frontpage and because of that a lot of people are probably unclear about the use of Snapshare. I’m gonna tell you a story of a problem I have faced many times before and what I hope Snapshare might be able to do to fix that problem.

I went to Italy on vacation this year with my girlfriend her family. And not just her parents were there but also here aunts and uncles. Everybody had a camera with them and we calculated that at the end of the vacation had about 1200 photo’s spread over 6 camera’s.
It’s been a few months already and I still only saw a handful of photo’s that people uploaded to various sites and because I’m too lazy to download the photo’s that are available I don’t own the photo’s myself.

With Snapshare I can upload my photo’s of the vacation (and so can everybody else who was there) and give me and the other family members access. My friends/family can then “Snap” photo’s of the vacation to their own album(s) or if they like all my photo’s snap the complete album to their own account. This way everybody has all the photo’s all the time.

From Snapshare it should be possible to export photo’s and albums to social websites like Flickr / Facebook or the dutch variant Hyves.

Snapshare is all about exchanging photo’s and building an complete photo archive. We will be upgrading this prototype after the competition is over so stay tuned.

All that rests is a small demo of the snapping functionality. In the demo I am snapping some vacation pictures my sister uploaded to my own account. I couldn’t get my sound working on Screenr so you must imagine my sexy voice narrating yourself.

Keep Snapping!

As always this script can be found on Gist too.

I wrote a tiny mail script to go with the syncer so I know of everything is working or not.

class SimpleMailer
require 'net/smtp'
  attr_accessor :email_from, :email_to
 
  def initialize(email_from, email_to)
    @email_from, @email_to = email_from, email_to
  end
 
  def happy_mail
    message = <<MSG
From: #{@email_from}
To: #{@email_to}
Subject: Succesfully synced database
On #{Time.now.strftime("%d-%m-%Y %H:%M")} the staging database was successfully synced.
MSG
    mail(message)
  end
 
  def sad_mail(problem)
    message = <<MSG
From: #{@email_from}
To: #{@email_to}
Subject: Problem syncing database
On #{Time.now.strftime("%d-%m-%Y %H:%M")} the staging database was NOT synced!
Problem: #{problem}
MSG
    mail(message)
  end
 
  def mail(message)
    Net::SMTP.start('crunch1.c1.noxa.nl') do |smtp|
        smtp.send_message message, @email_from, @email_to
    end
  end
end

I needed a small project that I could use to learn some basic bash scripting. Since I like automating things a unattended passenger installation seemed like a cool thing. It’s far from perfect but it gets the job done. (on Ubuntu 8.04/8.10 at least).

Feel free to post any improvements you may have.

You can find the gist here

- You can now see which users uploaded a project as long as that person had an account during the time he uploaded.
- It now shows how many times a project has been downloaded.
- There is a new tab on the frontpage with the “Top Users”. “Top Uploaders” could have been a better name but the tab is too small. It shows the top 5 users who uploaded the most projects.

That’s all folks!

I’m having some major problems with the screenshots in The DStillery’s gallery. That’s why today I made the decision that all project screenshots on the front page will be stretched (if they do not meet the requirements) to a resolution of 256×384 (a standard ds screenshot resolution). So no more distorted screenshots on the frontpage as long as you upload a normal ds screenshot.
If anyone out there can make it so that no matter what resolution the screenshots are in, the boxes containing them will still be the same size, please do! Because I just can’t seem to make it work.

Thanks to James I discovered my site looks totally bullocks in Internet Explorer 7 (and 6 for that matter but I think only my grandma uses that ancient thing), I’ve made some changes that should make it somewhat better but for The Full DStillery experience(™) please turn to Firefox.
Edit: Nevermind, still not working correctly in IE7…it will probably look messed up till the weekend, so little time, so much too do!

namespace :app do
  desc "Warble and Deploy"
  task :warble_and_deploy , :roles => [:app] do
    run "cd #{release_path}/ && warble"
    run "/bin/asadmin deploy --user admin --virtualservers #{virtual_server} --passwordfile /home/rails/passwordfile --contextroot / #{release_path}/#{warfile_name}"
  end
end

Now, that doesn’t look so hard does it? The recipe makes a few assumptions. First you will need to create a asadmin password file. To do so make a simple textfile with a simple string: “AS_ADMIN_PASSWORD=ieathashbrowniesonce”. The second thing is that we assume that your capistrano user has rights to access the warble gem.
Now all that is left is to define two extra capistrano variables. virtual_server is the virtualserver that your application is attached to and warfile_name the name of the warfile you are trying to deploy (as configured in your warble.rb file).
I’m not sure if this is actually the best way to deploy on glassfish using capistrano so if you know a better way please let me know.

I got my shiny black Nintendo DS a few weeks back. Before that I always hijacked my girlfriend’s DS but sitting on the public transport with a pink DS just go a bit weird when I received Guitar Hero. A pink DS is one thing, hitting your DS like a madman while ranting lyrics become really awkward so that’s why I finally bought one for myself. With my DS came a DSTT and since a DSTT is not so fun empty I decided to look around for some good homebrew. But the homebrew out there was like my heart after my first ex-girlfriend was done with it, scattered all over the place.

Around the same time I came across a great piece of open source software by RailsJedi called opensourcerails. The software powers a software gallery by the same name filled with Ruby on Rails projects. This would be perfect for a DS homebrew site! I made some minor modifications to the code, registered myself a fancy webdomain and filled it up so it wouldn’t be completely empty and this is where you come in. Every users/developer of DS homebrew is welcome to upload the games / applications they enjoy and host them here on The DStillery. Let’s take a look at some of the feautures.

• You can create projects
• Upload multiple screenshots for a project
• Upload multiple versions for a project
• Tag a project
• Leave comments
• See the number of downloads for a project
• Rate projects
• Bookmark projects

And the best thing is you don’t even need to create an account to do all these things! So show me you guys can handle that responsibility. The adjustments I made to the code are open source too so if you want to help out coding new features or just use it for your own projects please do.

My heart is all in one place again, let’s try to do the same for all that great homebrew out there.
