s3kup: the s3 backup tool

I’ve created a tool creating backups on a s3 bucket, I called it s3kup. It’s written in GO and very straightforward to use. It’s somehow a rewrite of an old ruby gem I had for the same purpose. It’s a command that can take any input from a shell pipeline and store it in a versioned way in a s3 bucket. s3kup has 3 basic commands: push, pull and list. Continue reading

Speed up your bundler = personal rubygems proxy with cloudfront

If you think your bundle install takes too long, or have a distributed team around the globe, this may help you. It’s possible to have a cloudfront server pointing to rubygems, and using it as your gems source server. (If you are not aware of what cloudfront is give a look at it) On this configuration, cloudfront will fetch requests from rubygems.org, and keep them cached on the CDN, so you should expect the first bundle install to take very close time of using rubygems.

Automatic git bisect


There are some situations that you found your build broken and need to know at what revision the “brokeness” was introduced.

git bisect is a great tool for that, basically you tell git at which revision the build was good (assuming HEAD is broken), and it does a binary search for the revision where the bug was introduced.

Keeping track of your deploys with capistrano and git

I’ve created a simple capistrano task to keep track of my deploys. When I deploy to a server, it will create a git tag and push it to origin. This way I can keep track of each deploy revision. after 'deploy:update_code', 'git:create_deploy_tag' namespace :git task :create_deploy_tag do puts "[git] creating new deploy tag" tag_name = "deploy--#{Time.now.strftime("%Y-%m-%d-%H-%M-%S")}" `git tag -a '#{tag_name}' -m 'Deploy: #{Time.now}' origin/production && git push origin --tags` end end p.

Android: Camera and Image Gallery


Here is some simple steps to access the phone camera and image gallery. This will be a very simple app. There is only one view, it will hold 2 buttons for selecting the image (one from camera and another from the gallery) and a ImageView that will show the selected image. I’ll not talk about the layout here, what I did is ugly and looks like this:
