How-to migrate your private github repositories to an external server

Because of the recent ruby/rails security scares I wanted to move our private github repository to a more secure location that is only accessible by our small team via ssh keys on an unknown port. It's worth remembering that private repos on github are not encrypted, and so are only as safe as the ruby/network layer that wraps it. To be fair, private repos were never advertised as secure storage, despite being used that way.

This is a huge 'if', but /if/ github is compromised not only will your sourcecode stand a high chance of being exposed (commercial damage, elevated risk of XSS & SQL injection), but your web applications may also be vulnerable to session spoofing in addition to possibly granting access via API keys and passwords to the usual range of external APIs, probably including commercial ones. We all code in a secure way, but who wants to have that tested in public?

It is trivially easy to mitigate this risk

Weirdly, there's not an awful lot of information on what makes a light, fast and modern Linux laptop on the internet, even for a popular distribution like Ubuntu. I like to run Ubuntu as, for better or worse, it's what we use on our production systems.

Normally with linux laptops, you run the gauntlet of esoteric specialist hardware matched up with shaky drivers - a sure fire recipe for burning a weekend (or few weeks even). It's such drudgery to have to plod through all this stuff. I need a decent laptop that I can install Ubuntu on and for everything to just work.

By everything, I mean all of it - wireless (b/g/n), gigabit ethernet, battery indicator, cpu stepping, VGA port/dongle, bluetooth, HDMI port, sleep, SD card reader, camera, microphone, usb, multitouch (especially two-finger scroll) and special laptop keys like brightness and volume. I wanted as near to zero config as possible with good default choices.

I decided to take an educated guess on such a linux laptop recently: the Samsung 350U (speci

	Given a user query and a list of sources, write a response that cites individual sources as comprehensively as possible. Each source is independent and might repeat or contradict content from other sources. The response should be directly supported by the given sources and cite them appropriately with a [i] notation following a statement that is supported by [i]. If a statement is based on multiple sources, all of these sources should be listed in the brackets, for example [i, j, k].

	TLDR; the €59/mo EX 4S scores higher (1729) than AWS m2.4xlarge (1511) on single threaded loads.
