IE blocks when managing rackspace rows in Racktables

RackTables
There is an incompatibility of Racktables with some Microsoft Office AddOns for the Internet Explorer.

If you are using Racktables with Internet Explorer and have installed the Office Document Cache Handler AddOn (part of Office 2010), you will have issues when managing rackspace rows. The CPU usage grows and the browser gets unresponsive.

Here are some workarounds which you can apply:
  1. You can use InPrivate browsing to fulfill this specific task.
  2. You can disable the AddOn. However you shouldn't do that if you are heavily using Sharepoint (see http://support.microsoft.com/kb/2463597 to notice why).

GMail got weak or spammers got clever? – GMail's Day of Spam

I never got 8 spam mails passing the GMails spam filter on a single day. It seems that today we have "GMail's Day of Spam". I have already received eight spam mails in my inbox and it's just 3 p.m. here. I will keep you up to date on the number of spam received today.

So what is your opinion? Did GMail get weak or did spammers get clever?

Update: spam mail number 9 received at 3:36 p.m.
Update 2: spam mail number 10 received at 4:36 p.m.
Update 3: spam mail number 11 received at 7:30 p.m.

Simple one line network scanner in Linux

Once in a while one has to scan a network segment to find out the IP address of a device. This is possible without installing any tool by using a simple linux shell one-line script:
for i in $(seq 255); do ping -c 1 -w 1 10.1.1.$i | grep "bytes from"; done;
Of course you have to configure the IP range scanned to match your subnet.
