This PDF credits include Mark Roper. The corresponding video is: Mark Roper - My Puzzle Robot is 200x Faster Than a Human https://youtu.be/Sqr-PdVYhY4

Small correction: It's Mark Rober, not Roper

A typo I can no longer correct. That will be a thorn in my side now.

Mark Roþer. There (and yes, that's very wrong).

As well as Shane: https://www.youtube.com/watch?v=WsPHBD5NsS0

Which is basically a total rip-off of the Stuff Made Here version where the actual engineering process is the highlight, not Rober's shilling. https://www.youtube.com/watch?v=Gu_1S77XkiM

That video is linked literally in the first paragraph of the PDF.

The video also starts with him acknowledging the Stuff Made Here version, and the fact that the developer of that project said he wasn't totally satisfied with his solution.

I think calling it a rip-off is a bit harsh.

He also pointed out that the Stuff Made Here video came out well after they had already started.

Mark Rober doesn't do any engineering himself, he's the CEO who claims credit for what other people do.

For example, he didn't create the glitter bomb, his most viewed video. That was done by Sean Hodgins (making-of video: https://www.youtube.com/watch?v=IpMxOmUcfOI). Sean's name was not mentioned at all in the glitter bomb video. Instead, Mark Rober claimed he built it by himself.

Ugh, that's disappointing. My son really likes Mark, we've been watching his videos and even got this Build Boxes things to build every month. Sean got 300K views and Mark Robers video 91M.

Mark claims he built it https://youtu.be/xoxhDk-hwuo?list=PLgeXOVaJo_gnexNopBzUKdl3Q..., he had the sketch done first and the CAD drawings, the he "hit up his buddy Sean, who is good with this type of small electronic stuff". So Mark claims Sean did just the electronics.

This was added afterwards after some outcry. It's annoying that YouTube doesn't notify whether the video was edited after the fact, like Reddit/Hacker News does.

That is sneaky. At least they decided to update the video. But overall it's pretty disappointing. Mark is playing this meek, super nice guy persona on the screen. It's just camera play acting to attract young viewers. Oh well, it's good to know. Thanks for mentioning it.

Code of the said robot on github: https://github.com/roksenhorn/puzzle-bot

I once tried a puzzle with a significant amount of almost completely black pieces. It was faster to just brute force the pieces than to even bother looking at their shape. All you do is sort the pieces by the number of tabs/holes, look at a specific spot you want to fill and then mindlessly try every eligible piece.

This is basically my end game strategy for puzzles once all the parts with distinguishing patterns has been solved and you’re left with e.g. a bunch of blue sky pieces. It’s a bit dull, especially the sorting st the beginning, but it gets satisfyingly faster as you near the end and the number of candidates gets progressively smaller.

It depends on the puzzle, but one problem here is when there's multiple possible pieces that fit. I have a 3000-piece puzzle where the blue sky was like this: many of the pieces were nearly identical, so there were multiple pieces that could fit together at any point. You'd only figure it a piece was in the wrong place when you couldn't fit any of the neighbors.

Yes, I was introduced to the concept through this project first.

What's the connection with shopify?

Looks like the PDF was uploaded to his crunchlabs.com site, which is hosted by Shopify.

With a bit of digging, I believe this is the source Google Doc: https://docs.google.com/document/d/1BUCGdZCe8JevGYF3pJ4ZjPqp...

This sounds like the perfect leetcode style toxic interview problem

Was literally talking to my friend about this concept yesterday
