Problem of the day : I wasn’t able to connect to Heroku from my mac. The process was blocked on the message « Installing CLI… » like if it couldn’t connect to Heroku.

MacBook-Air-de-Laila:shredder leiluspocus$ heroku login
heroku-cli: Installing CLI...

I noticed my Bluetooth was active. It worked after I disabled it.

Write a new task using Capistrano

Capistrano can be a great tool to run a task on several servers. It can be a task like uploading a maintenance page or deleting some logs :

task :NAME_OF_YOUR_TASK do
desc &lt;&lt;-DESC
This is my awesome task. Description appears in help so write it carefully.
DESC
run "rm -rf #{logs_folder}"
run "mkdir #{destination_folder}"
top.upload("index.html", "#{destination_folder}/index.html")
end

You can read more about writing Capistrano tasks here.

Create a copy of a Vagrant machine

Stop your vagrant machine

vagrant halt

Create the copy (it can take sometime)

vagrant package --base name_of_your_machine  --output path/to/newly/created/package

The machine name is on Virtual Box 🙂

I had the weirdest issue when initializing my compass project for Greenie.

>>> Compass is watching for changes. Press Ctrl-C to Stop.

I solved it by using a more recent version of Ruby using RVM. RVM is pretty cool because you can switch your Ruby versions very easily. Note that I had to re-install compass afterwards.

Here is a couple of commands I’ve used in a previous life while trying to resize a Vagrant machine.

List the virtual disk images used by Virtual Box

vboxmanage list hdds

Remove a hard disk from a Virtual Box registry

vboxmanage closemedium disk a5bad1ba-5ff7-4b83-87ff-adb18f05269a --delete
