SMS Gateway
I have yet to try them out, but Clickatell seems like a nice, developer friendly SMS gateway.
UPDATE:
They offer a trail account where you get a few messages for free (although they override the message content with a default text), so I couldn’t resist and tried it out.
It’s really a matter of minutes if not seconds to get started:
schmidp@dna:~$ curl -i “http://api.clickatell.com/http/sendmsg?user=$USER&password=$PASSWORD&api_id=$APIID &to=$TO&from=$FROM&text=$TEXT”
HTTP/1.1 200 OK

I have not yet compared their prices with other gateway providers, but I don’t have a real need for it now.
Enable SSH Agent (Key) Forwarding on Snow Leopard
I’m using Git and Capistrano to deploy some ruby applications on multiple servers. My Git setup is done with gitosis which uses a key based authentication over ssh. The deployment script logs into the remote servers and checks out the current application version via Git.
Now to have this working, one must forward the private key, used to authenticate with git, to the server which does the checkout. This is done by the ssh-agent process, which whom you can register your keys by running the command ssh-add.
After switching to Snow Leopard, my deployment script stopped working, because somehow the ssh key didn’t get forwarded to the server and I was presented with a login prompt: “Enter password for git@git.gitserver.local:”. Of course I don’t have a password, because gitosis uses key based authentication only.
To make a long story short, Snow Leopard ships with key forwarding disabled by default and you will have to modify the file /etc/ssh_config to get it working.
Just change the lines
# Host *
# ForwardAgent no
# ForwardAgent no
into
Host *
ForwardAgent yes
ForwardAgent yes
and you are good.
