LOL, I didn’t know about “XKCD Explained”, but since I didn’t know about synesthesia, I found 1213: Combination Vision Test – explain xkcd.
Now I wonder how they created the colorized picture in an efficient manner (:
Probably would have been just as fast to dim the 0, 4, 6, and 8 digits.

Sometimes I get messages like the below No Disk error on virtual machines, mainly in Windows XP and lower, but sometimes in more recent Windows versions too.
---------------------------
Windows - No Disk
---------------------------
Exception Processing Message c0000013 Parameters 75b6bf7c 4 75b6bf7c 75b6bf7c
---------------------------
Cancel Try Again Continue
---------------------------
The 0xc0000013 is a No Disk Exception.
Every time the solution has been to uninstall the floppy drive device from the VM image.
I never had it on physical hardware, but for that, disabling all unused removable and USB disk devices seem to work.
Somehow, lots of software thinks it should scan ALL media, even the removable ones that might not have media inserted.

Nobody but very wealthy research institutions could afford CRAY machines.
They were the computing workhorse of their time. Now your smartphone is faster (:
BitSavers just added a bunch of CRAY documentation of the 1980s and early 1990s.

For 10 months ago, Iris started Asking a ‘stupid’ question, every day for 365 days.
Virtually all of them very valid questions that remind me of various stages in my software career, and will remind me during the stages still to come.
Her motto is “there is no such thing as a stupid question”.
I agree, and would go even further: keep the questions coming every day of your life, as it is the only way of learning.
Recommended reading!

It is unwise to pass objects allocated in one framework over a DLL boundary to a different framework.
In the case of Using C dll in delphi return nothing, someone tries to pass an Interface to some memory in the C side over to Delphi.
Unless that interface is COM based, don’t do that!
In a more general way: don’t pass memory allocated on the DLL side over to the client side, no matter what kind of client you have.
From the DLL, either pass simple types, or fill buffers allocated at the client side.
