IIUM Convocation 2013 Fiesta coming soon

Wheee.. The time is flying fast. Next month would be the robe collection, and then would start a series of photo taking and sweaty eyebrows.

The days from 16th November till 18th November are going to fly. Festive mood, families from everywhere.. Ahhh my turn at last..

SOLVED | VirtualBoX | Guest OS Inaccesible

 So I want to work with Instant Contiki, and do some more coding when I get the shock of my life.

Instant Contiki Inaccessible.

All my work inaccessible.

The screen shot of the potential-heart-attack situation is attached: (Click to view a larger version)

Basically the following error was generated:

Runtime error opening 'C:\Users\Mamoon\VirtualBox VMs\Instant Contiki\Instant Contiki.vbox' for for reading: -102 (File not found.).

D:\tinderbox\win-4.2\src\VBox\Main\src-server\MachineImpl.cpp[724] (long __thiscall Machine::registeredInit(void)).

Result Code: E_FAIL (0x80004005)
Component: Machine
Interface: IMachine {22781af3-1c96-4126-9edf-67a020e0e858}

 Luckily I found this solution here:

"Look in the folder that has the guest and see if there is a *.vbox-prev file. If so (make a backup of it) and rename it to remove the -prev."

Renamed the thing, backuped the file and ran VirtualBox. Folder looks like this now.

There, good as new.. Better to back up these files somewhere on the Cloud before I lose months of work, thanks to a silly shutdown issue.

Packet Delivery Ratio Formula

The total packets received at the receiver divided by the total packets originally sent.
