I have recently watched the MythBuster episode whereby the "fans" felt Jamie was wrong, when he mentioned that "That's equivalent to a single impact going in to a solid wall at a hundred miles an hour" for the compact-compact episode, whereby he was referring to the equivalence of two trucks slamming into a compact car at 50 mph each at the same time from opposite directions.

In the followup episode they tested slamming a car at 100mph into a solid wall, and then subsequently two cars going at 50mph each, into one another. From their results they deduced that Jamie was wrong, and that two cars crashing into each other at 50mph is equivalent to one car crashing into a solid wall at 50mph based on the amount of crumpling that occurred, as well as the forces at play as measured by a force meter in the back of the car(s) - and not 100mph into a solid wall as Jamie mentioned.

This is not a trivial issue, as it does not depend on standard rigid body physics taught in high school or even entry level university courses. That is where I believe most people (and even the producers) went wrong with this whole thing.

I had a weird issue where I could connect just fine to any VM on any of my many HyperV enabled servers… Except one. I just installed a new Windows Server 2008 R2 SP1 in a HyperV VM and the RDP connection was horrible slow. No network traffic, no CPU… Eventually I found this article and in specific, NicMic's comment worked for me.

You have to disable IPv4 Checksum Offload in the Virtual Machine's NIC adapter.

I get why Apple introduced the new automatic save feature - it will certainly assist people new to computers to not lose work. However it is not thought through very well.

The problem? OmniGraffle has been updated recently to support this new feature. However as anyone using OmniGraffle knows, saving a large document can take some time. My document takes 10 seconds to save. That means whenever I move focus off the document or in to the document, this thing goes into autosave mode and I get a nice spinning beachball.

I had a complaint from my one client that their Android phones do not sync anymore to Exchange server via Activesync. I tried to connect to OWA by going to http://server/exchange, and I got the login prompt. Typed in the username / password and it took me to a directory listing. Not what I expected.

To troubleshoot this I compared the settings in IIS for Exchange, ExchWeb and Microsoft-Server-ActiveSync to a known working 2003 server. The settings all seemed perfect, yet it failed to work properly. So eventually I found this article.

The steps I copied from his explanation worked perfectly.

Anyone who has a keen interest in things computer related might have heard about the new flame war going on regarding the proposal to drop the version number from Firefox. This is part of a bigger goal to do away with the traditional release cycle where a major version is released every couple of years, including major changes. Instead, Firefox took merely 2 months to jump from the first 5.0 release to the 6.0 release, which has been officially released today.

There are several issues that I have with this. Firstly, you need to understand that dropping the version number is a very bad idea. I understand why they want to do it - with the change in release schedule the version number does not indicate significant releases anymore. There are more changes I believe between 3.6 and 3.6.19, than between 5.0 and 6.0 IMO. That being said, version numbers are still paramount.

From a usability perspective it might make sense - just state whether you are on the latest release or not, and show when last the browser checked for updates. In a modern world this might be a reasonable approach. But it breaks down completely.
