Welcome

Welcome to my home page.

new phone!

I now have a HTC Desire!
This phone is really cool.
I'll be using it to port the IPhone version of scanbizcards.com to the Android platform.

I haven't the time lately to develop my open-id provider, but I'll get to it sometime....

Android

I am now developing an Android App! I like the android platform -- to bad you can't buy Nexus One anymore :-)
When I'll finish that, I'll have some more free time to finish the openid provider (which is now at pre-alpha stage!)

Freenet

I just installed Freenet client. It was very easy - using the JavaWebStart installer, and the configuration wizard.

For those who do not know, Freenet is an attempt to create an anonymous Internet. This is good for some countries in the world, where people track what you think... It been around here from the year 2000. I know it for some time now, and finally decided to try it out.

I could not find a lot of interesting content on Freenet, but I'm just beginning to explore it...

Ubuntu vs Windows Boot times

On my laptop, I have both Ubuntu 10.04 and Windows 7 installed and dual-booting. I have decided to compare the boot times of both systems.

Easy Password Maker Explained

Well.. Managing your passwords is not an easy task...

The problem is, that every person has multiple web accounts, each requiring a password....
You have several options:

  • Remember all your passwords. That's hard. That's why people use the same password over and over.
  • Use a password Manager - A tool that saves all your passwords using a master password.
  • Use OpenId.

Well, using the same password (even if it is a strong password) is not a good idea - You put your trust on to many services, that might or might not keep it to them selves.

Accessing your web accounts without revealing your password

In my article from 7/2009 on how to access your email (actually, any web service!) with challenge-response.
The reason that you event want to do that, is to avoid risking your private password by typing it in a public computer.

I am currently working (on my limited free time) on an implementation of a Challenge-Response OpenID provider. When I thought of the idea, I searched the web, and found that a a group of students at Stanford had already done it. In my opinion, their solution (called Snap2Pass) is good, but hard to deploy (as it requires a chat server).

Additionally, Windows Live Mail has a nice (and simillar) feature: single use code.
