my credit card was hacked in dubai. either the staff of Alkhoory hotel apartment, europcar or lulu hypermarket did it.  It was issued by Arab Bank Amman/Jordan. I reported it and got the money after 60 days back! 

if you report, you get the old card stopped and a new one issued with all the old credit/accumulated reward points moved from the old card to the new one. The stolen amounts will be payed back within 60 days.

bug of drag and drop when the host of virtualbox is mac, and the guest is windows.
after you save the session of the guest and load the session, the drag and drop does not work.

flickering screen on macbook pro
non working usb suddenly with message " To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may have also been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again."
this happens occasionally, I found out that it disappears when I press the body of laptop firmly (the area around the enter key). Apparently something is loose and it moves and disables the usb and/or causing the flickering. a quick fix only.
