I'll consider this is a note for myself in this blog.
However, it's always nice to share.
I downloaded an Ubuntu Desktop iso on my new upgraded macOS Sierra.
The iMac it's self is old, it's mid 2010 which still have a old device - super drive.
I was dragging so hard from the iso file to the Disk Utility everywhere but nothing really happens.
Finally, luckily, I've found it's not that hard anymore.
Open the Finder and point to the location of your iso file.
In my case, it's under my Downloads
Now under menu File, you'll see the Burn Disk Image "xxx" to Disc...
Press that one and it'll ask you to put empty DVD disc to your superdrive
And you'll have the Ubuntu installation disk in no time.
Just bought a new Logitech m187 Wireless Mini Mouse from Walmart.
And my Windows 7 was not able to find any driver for it.
Luckily to have a this article help me a lot.
Error Message :
USB Receiver : No driver found
There should be a C:\Windows\INF\usb.inf.
And it's gone.
Go to C:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_neutral<something>
Copy usb.inf & usb.pnf to C:\Windows\INF
And uninstall the unknown driver and try to search automatically for updated driver software.

I wish no one use this skill to do anything bad.
The original idea was to modify some program logic from my previous Excel VBA master.
I'm just a very very normal IT guy.
First of all you need a Hex editor.
Open your Excel file in the Hex editor.
Find the DPB in the file (In ASCII mode of course)
Then modify the B to anything else, in the discussion of Google Group Shameer suggested to use x.
So that would change the DPB to DPx.
Now save your file.
Open up your modified Excel, lots of error messages popup.
Just keep press OK.
Now ALT+F11 to open up your VBA Editor, you'll see the password now is empty!
Now you can change it to something else save it back, and everything will be back.
Cool, isn't it?
