Periods of drought reveals historic landscape and soil changes

Posted by jpluimers on 2019/03/18

Periods of long drought can reveal historic changes in the landscape and soil.

One example was posted last year at [] Je bent een Sassemer als … of the natural ice staking area in Sassenheim, The Netherlands, which is part of a polder.

Historically, creeks were running through it, and later on drainage tubes were laid into the ground:

PS/2 port colours – Wikipedia

Posted by jpluimers on 2019/03/11

I always forget which colours the [WayBackPS/2 port for keyboard and mouse have.

Some of my old (some call it classic or vintage) mice and keyboards don’t even have a coloured plug.

Luckily, Wikipedia has the answer File:Ps-2-ports.jpg – Wikipedia :

Color Description
Purple Keyboard
Green Mouse

To celebrate his 85th birthday, some links to interviews with Niklaus Wirth interviews

Posted by jpluimers on 2019/02/15

Today, Niklaus Wirth, “father” of The Pascal Programming Language turned 85.

Happy birthday!

Almost 50 years ago, Niklaus Wirth submitted his famous paper “The Programming Language Pascal” which was published early 1971

Luckily it is archived on both the WayBack machine and as the only PDF copy I could find on-line isn’t always on-line:

Originally it was published by Niklaus Wirth  in Acta Informatica, Vol. 1, Fasc. 1, 1971 pp. 35-63

He has been very active, just browse through the [WayBack] List of computer science publications by Niklaus Wirth

To celebrate his birthday, here are some interviews with him:

If you like the ones above as much as I do, then search for more: there are plenty!
