None. There is absolutely none.

I always suspected that but now I’m sure.

MAC Addresses are unique to the networkcard and can be used to identify your PC.

You can view your MAC addresses by typing ipconfig /all

Ethernet adapter Loopback:
  Connection-specific DNS Suffix  . :
  Description . . . . . . . . . . . : Microsoft Loopback Adapter
  Physical Address. . . . . . . . . : 02-00-4C-4F-4F-50
  DHCP Enabled. . . . . . . . . . . : No
  Autoconfiguration Enabled . . . . : Yes
  IPv4 Address. . . . . . . . . . . : 111.111.111.111(Preferred)
  Subnet Mask . . . . . . . . . . . : 255.255.255.0
  Default Gateway . . . . . . . . . : 0.0.0.0
  DNS Servers . . . . . . . . . . . : 111.111.111.111
  NetBIOS over Tcpip. . . . . . . . : Enabled

to view other machines MAC addresses you can ping them and then type arp -a which wil result in a list similar to this:

Interface: 192.168.1.200 --- 0xb
  Internet Address      Physical Address      Type
  192.168.1.1           00-04-0e-f6-17-55     dynamic
  192.168.1.2           00-04-0e-aa-88-ab     dynamic
  192.168.1.3           00-01-db-09-55-42     dynamic

The first three bytes identify the manufacturer of the card, the remainder identifies the card itself. 

you can look those up here:

Ever wanted to test your Anti-Virus program?
 
Use the Anti-Virus Test File from the European Institute for Computer Antivirus Research (Eicar).

dasBlog is great, but it uses an older version of the nice freeTextbox to edit the posts.

This little editor provides great enhancments for editing and formatting, and IE8 is known from Version 3.2.0, but thats not the version we are using in dasBlog.
Luckily IE8 has a 'Compatibility View' setting, which defines a list of websites that will receive the old (IE7) user-agent string.

If you own the website, you can set the compat mode using a meta-tag:

<meta http-equiv="X-UA-Compatible" content="IE=7" />

So, this weekend I completed the move from simpleBlog to dasBlog, changing technology from PHP (which was good) to ASP.NET which is more suitable.
The content has to be migrated too, which will follow on one of the next weekends.

Coding conventions are for whimps :-)
 
I like that:
It's written for JAVA :-), but it matches other languages like C# too.

Working with a Microsoft CA, you often need to query the CA's database.
To determine the schema of the database you can use certutil to view it:

certutil -schema

this will list the columns, their types, their length and if they are indexed.

Sample:
c:\Program Files\Microsoft Visual Studio 8\VC>certutil -schema
Schema:
