SSH agent forwarding and screen

When connecting to a remote server via SSH it is often convenient to use SSH agent forwarding so that you don't need a separate keypair on that server for connecting to further servers.

This is enabled by adding the

ForwardAgent yes

option to any of your Host entries in ~/.ssh/config (or alternatively with the -A option). Don't set this option in a wildcard Host * section since any user on the remote server that can bypass file permissions can now als use keys loaded in your SSH agent. So only use this with hosts you trust.

A slightly updated version of this doc is here on my website.

Why I Like Go

I visited with PagerDuty yesterday for a little Friday beer and pizza. While there I got started talking about Go. I was asked by Alex, their CEO, why I liked it. Several other people have asked me the same question recently, so I figured it was worth posting.

Goroutines

The first 1/2 of Go's concurrency story. Lightweight, concurrent function execution. You can spawn tons of these if needed and the Go runtime multiplexes them onto the configured number of CPUs/Threads as needed. They start with a super small stack that can grow (and shrink) via dynamic allocation (and freeing). They are as simple as go f(x), where f() is a function.

I have now hit my first "wow" moment with Rails, where I actually understood why it has the following it does. It has raised some questions for me about the pedagogy of Rails, but that is not the language's fault; it is a question for the community.

Rails is fast. Mind-blowingly fast. From my cursory looks at the framework, it is immediately apparent that this was designed from the ground up to give me everything I'm going to inevitably want in a basic web application. And yet, for some reason, it isn't immediately sold that way. It's instead sold with stuff like...

"I'm not even joking when I say this, but I think some of the resources out there make it intentionally hard for non-technical people to start learning."

The above line was from a class on Rails - not a Ruby class, but a Rails class. The class was designed so that you could have no coding experience whatsoever and build an MVP, and it advertises itself as such. I think learning to code, even at the lowest level of difficulty, is a fantast

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
