As in Old Russian will be "this is a test"

Today, we all without thinking will type “this is a test” if we need to try a new editor or a programming language for the first time:

10 PRINT "This is a test" 

But has it always been like this?

Let's celebrate the Programmer's Day, looking at what one of the most ancient examples of “This is a test” looked like in Russia.

Somewhere in the year 1350, an unknown Pskovite was learning the new system “Birch bark 1.0”. It is already difficult for us to imagine exactly how in those ancient times people mastered new technologies. Probably, they simply asked each other, and perhaps they read Figurnov.

Anyway, here is the first document he wrote down:



"I'll eat." That is, "[I] try." That is, "This is a test." Not monospaced font. Without caps.

He did not put a geo-tag, but we will do it for him: 58 ° 30'58 "N 31 ° 16'21" E

It seems to me that if for some reason someone wants to make a logo on the theme of “Russian programming,” this birch bark and this inscription should have been on it.

(It is not a serious scientific research. Birch baptislama is real, but free of photography. The translation is correct .)
