[link] Improving the security of your SSH private key files

Nice article on SSH:

Ever wondered how those key files in ~/.ssh actually work? How secure are they actually?

As you probably do too, I use ssh many times every single day — every git fetchand git push, every deploy, every login to a server. And recently I realised that to me, ssh was just some crypto voodoo that I had become accustomed to using, but I didn’t really understand. That’s a shame — I like to know how stuff works. So I went on a little journey of discovery, and here are some of the things I found.

Direct config of Linux firewall with iptables

There are several firewall applications for Linux, but what you may not realize is that, at the heart of all these programs is a single all-mighty application that is built right into the Linux Kernel: iptables. This is the Linux firewall. No matter which program you use to configure your firewall under Linux, it ultimately all comes down to iptables. All that these other programs do is configure it.

So, here comes the question: if those programs simply configure iptables, why not simply configure it directly yourself? Doing so is easier than you might think!

Could this be the next big thing for CI and other highly managed development processes?
At first blush it looks good, so I’m posting it to investigate later…

Intern takes the stress out of testing your Web app.
Run tests using the browser or node.js and seamlessly integrate withSauceLabs or Selenium. Write tests using object, TDD, or BDD styles and get full code coverage reporting with Istanbul. Continuous integration? Intern has you covered with Travis CI support out-of-the-box.

Bye bye Posterous – important info for all readers

Well that was a shame…

Twitter bought Posterous a while ago, and canned it. So, I’ve switched blogs, and of course, most of my posts are massively messed up. It will probably take a while before I can get a decent theme fixed up [finally done] and the old posts correctly formatted [still not complete…], so in the meantime, please excuse any screwed up posts you find.
