SSH login with a certificate (Windows)

May 2nd, 2011 Posted in security, technology, work | 4 Comments »

One of the most convenient ways to login to a server with SSH, is with certificates. Although the principle is pretty well documented all over the internet, I still found some issues setting it up myself from my Windows laptop, hence this walk through.

I have tried to make a simple, condensed walk through. It does require that you know what SSH is and how to use PuTTY.

(I also created a Mac OSX walk through)

The principle of security lies in separation of duty and protecting the core system, even if a component fails.

If you expect a component to fail, and it will, then you are better prepared to deal with it than if it catches you by surprise. There are so many exploits out there that denying a failure or security breach is only for the stupid and naive.

tactile keyboard for iPad?!

August 5th, 2010 Posted in technology | No Comments »

I bought an iPad and like it a lot, apart from the smudges. However there is (at least) one thing I noticed which is weird: The on-screen keyboard has some decoration on the letter f and j. On a normal ‘real’ keyboard these little bumps are there to position your fingers, especially when typing blindly.

But the iPad keyboard is completely flat. So why did they put in these little stripes? I totally don’t get it. Is it overcompensating usability? Or just some form of eye-candy?

Just look at this picture, to see for yourself!
