Nitobi just released version 1.0 of the mobile app framework Phonegap.
Phonegap enables you to write HTML5 and javascript pages and compile them into a mobile phone application (app). Phonegap currently supports iOS, Android, Blackberry, webOS, Bada and Symbian.
Phonegap also gives you some java script functionality that lets you use the GPS or accelerator in the phones.
Some big companies are taking part in the development like Adobe, IBM, Alcatel-Lucent, Cisco, Logitech or Time Warner.

I ran into the problem that I couldn’t get my DomU’s on a Hetzner EQ4 to connect to the internet.
Unfortunately this is because of the strange network settings Hetzner is using. There is a German manual how to set up a XEN server in their environment, but it is missing one really important part. Hetzner limits the access on their network equipment to the MAC address of your server. Hetzner is not giving you the possibility to set / create new MAC addresses for subnets.
Assuming you are using Debian Squeeze and your server is already set up, you will have to set a point to point connection in the Dom0 and each DomU.
DomO has the regular ip 178.x.x.x and one from the subnet 88.x.x.x – gateway is 178.x.x.1.
Edit the /etc/network/interfaces and add pointtopoint 178.x.x.1 after gateway. This should be the same ip address as your gateway.
For the routing you need one ip address of your subnet on the Dom0 installed. This will also be your default gateway for all DomU’s.
Add the default gateway as a pointopoint connection on every DomU and it should work.
Don’t forget to restart network or reboot the machine and instances.

Good news! Same trick as described on my post about Checkpoint secureclient and Mac OS X Snow Leopard works on Mac OS Lion. So no worries when upgrading.

This book is already a couple of years old, but for me it is still an inspiration from time to time.
The full title is Founders at Work: Stories of Startups’ Early Days (Recipes: a Problem-Solution Ap)

I just found this interesting guest article of Andy Gelfond (VP Engineering at TripAdvisor) on highscalability.com.
He is describing how they are solving daily issues as well as showing how they are working within teams. Quite interesting for everyone interested in high traffic projects.

Just found an article about a new “autoloader” tool for JavaScript called box.js.
It seems super simple and only loads the javascript code needed on a page. Will test it in one of my new projects and update this post.

Rumours say Apple is about to release the next version of Mac OS X called Lion TODAY.
To be honest I can’t wait to see what Apple has developed the last two years on.
Common Apple, released the next cat.
