On this #FreeCADFriday, I’m using the #Gridfinity and Part Design workbenches to make some screwdriver trays for my toolbox. The cool thing about these is that the cutout shape is the same between trays, but I only have to tweak the dimensions for each specific screwdriver. (All of mine are different)
I also made one to hold a hex bit holder that I designed and printed a few years ago. That one is a half-width tray because I have a half row at one end of my toolbox drawer.

Here is part of a CIA map of Libya - I'm using it because it's public domain. It comes from here:
loc.getarchive.net/media/libya
(A Library of Congress site with public domain maps. Can be a handy resource! The Schiaparelli map was from Wikimedia Commons.)
Surt, Sidra - they are forms of the latin name Syrtis, a marsh, and Syrtis Major was a large marshy area along the coast here. So it is a place on Earth like the others. Are all those names from Earth? #maps #Mars
irrelevant nitpick, but people from Huelva (onubenses) may get offended if you pin Rio Tinto to their adjacent province of Cádiz instead 😉
Finally - Amazonis. The name makes us think of the Amazon in Brazil, but originally it was the name of a female warrior society whose tales crop up all over the place in classical contexts. Amazons fought on the side of Troy in the Trojan war and are usually associated with northern Turkey.
OK, enough names. Now we will return to our sequence of Mars maps. #maps #Mars
That last map was drawn in the year of Sputnik. Direct exploration by spacecraft was not far off, so NASA needed a new map. The job went to the US Army and Air Force, who both had large mapping agencies and were gearing up for Moon mapping. I will show the Air Force map. You can see it here:

Look at that - it has canals! So did the less aesthetically pleasing Army maps. It's a curious footnote of Mars mapping history. #maps #Mars
MEC-1 Prototype

I positioned the images like this. Using a modern map as a background, I matched each Mariner 4 image to surface features. At the time this was impossible, In fact the bright markings in the top image (frame 1) were thought to be clouds, but my comparison shows every one is a real surface feature. Compare with this contemporary map (this time on the US Army base map). It shows #1 reaching nearly to 50 north, but it really gets only to 30 north.

Those were my maps for Mariner 4. What did maps look like at the time? The US Air Force made maps of the image pairs, and 4 of them are here:

A person usually associated with Pluto - Clyde Tombaugh - also mapped Mars and made a special map of the Mariner 4 target area. It's here:

South is at the top. He maps canals using an idea of the time: they are cracks made by impacts, so he maps craters at intersections (oases). #maps #Mars
mind-blown! I went and searched for more info, this page gave some hints
nssdc.gsfc.nasa.gov/nmc/experi…
but it wasn't enough, found this paper too to read later

Maybe there are better ones?
I'm guessing the Martian weather was negligible to affect the topographic profiles?
(I know, these are Mariner 9, but I wasn't aware one could do topographic profiles with UV measurings 😉 )
This text from the above paper makes it click for me. Also attach a couple good figures there.

How do you do, fellow web developers? A growing disconnect.

<- programmers increasingly don't know how programs work, or that there is a web that doesn't involve Javascript frameworks.
Apparently.

My two favorite interview answers I got a while ago:
- What is the complexity of this algorithm?
- Um, I see no complexity, it's quite straightforward.
And:
- On what protocol level ports are implemented? [asked in the middle of a talk about HTTP]
- Not sure, I think USB?
Those people were not joking, and I'm sure they also weren't dumb, but I still can't get used to the context gap that I have with many people with web development background.
