Microsoft Surface vs. Perspective Pixel’s Multi-touch (Jeff Han)

May 30, 2007

I was looking at gizmodo.com and saw this post about Bill Gates who revealed MS Surface on the Today Show – which is an interactive screen technology. I’ve also seen Jeff Han’s Multi-touch system which has been shown on various websites. Between the two, Microsoft’s product seems to be more refined but considering the resources it has, it’s not a fair comparison. I’m wondering really who was the first to create the working technology though they differ. I really like Jeff Han’s Multi-Touch technology considering that the solution is using an actual flat panel display as we see a small version to a very huge screen being used by actual people. MS surface relies on cameras which might have other limitations. I’ve played with a limited demo at the Microsoft Office 2007 launch event. It was a comprised of a projector on a scaffold and several cameras mounted on it, facing a large screen which allows it to be interactive on the projected surface. I personally didn’t like having my shadow being cast upon it. The MS Surface video showed a enclosed cabinet with projector running in reverse from what I can tell – so perhaps a larger scale enclosure like a rear projection TV.

Have a look at both MS Surface and Jeff Han’s Multi-Touch system and decide for yourself.

Here are a few links to Jeff Han’s presentations from TED and his company – Pixel Perspectives. If you look at the demo screen carefully – the OS looks like some sort of Linux running the Gnome desktop.

Update: 6/12/07 – There’s been a lot of traffic on this post – you might want to check out my post about MS Surface and Reactrix also. The system from Reactrix has been around for a long while and it’s technical design is almost the same.

Vmware broke after Ubuntu Kernel Updates

May 29, 2007

Well as I predicted my Vmware install failed to start after the kernel updates that I downloaded and installed. Since there is a new version of VMware available now – 1.03. I decided it was time to upgrade my installation anyways – this would mean a full install.

So on my Ubuntu Feisty – there is a great tutorial that I followed from howtoforge.net that outline how to go about getting vmware to run on Ubuntu Feisty. Note the part about the patch that is required since even the latest version of Vmware Server doesn’t compile properly using the new kernel headers.

This how-to guide was a little dated so after a little looking around on the vmware forums – I came across a post with the newest source for the patch.

Just follow the tutorial on HowToForge.net and substitute the newer patch.

howtoforge.net is an excellent source for the newbie admin who wants to learn more about building out more different flavours of Linux and open source solutions.

Ubuntu mailing lists

May 29, 2007

If you like to stay on top of the security updates, news and ongoing issues with Ubuntu, you might consider signing up to their mailing lists. I personally subscribe to the security mailing list to stay abreast on any potential security issues that might arise on my PC or servers. You can access their mailing list here.

There is also the community support if you need other resources of information.

Also checkout the Ubuntu Unofficial FAQ – There are version specific FAQs online – here’s the one for Feisty!

Recent Security Patches for Ubuntu

May 29, 2007

I hope everyone running their Ubuntu is staying up with the latest patches. There has been a recent flurry of updates, well at least on my system. Especially the update for the Ubuntu Kernel is one that requires a reboot. The last time I updated my kernel, the vmware server I was running wouldn’t work since it wasn’t compiled for the specific version of the new kernel. Again a little bit of research on the forums lead to an solution.

To keep things updated just do the following – I really recommend a high speed connection when doing so.

System > Administration > Update Manager

Update Manager

Double click on the Check Button – it might prompt you for your password – this is just a security measure that’s built in. Once you update you may or may not have to reboot. I’ve only noticed updates that require reboots when it pertains to the kernel. There will be a recycle icon that appears in your Panel or the equivalent of the windows bar that indicates that a recent update requires a reboot.
