That was for putting back the farm claims along the Nile. Professional rope stretchers did that.

This was paced.

Would you consider the product you provide a BIM product?

I think what is fascinating about this space is that the tech is there for full 3d models, machine control, and BIM smart design.

It's all just so expensive, only the huge companies get deep into all of it. As a PLS, we've been delivering site topos for decades with full 3d surfaces, only to deliver those to the engineers and after design they print out a plan set.

FYI. If you're talking about the stuff in the big round trucks that final product is concrete. Cement is an ingredient in concrete, a chemical binder.

Normally for "sidewalk concrete" that binder is an ingredient called "Portland cement", and the final product is "Portland cement concrete" or P.C.C. Probably the stuff your friend is working with.

For road paving, often referred to as black-top, the binder is Asphalt, and that is called "Asphaltic Concrete," or A.C.

And of course these terms might be local as well, this is what we call them in Southern California.

But the fact that the smaller company doesn't computer control and errs on the side of caution is a great illustration of the difficulty of working in this space. And that 10 miles can make a difference. I believe it!

For large road projects in the boonies they typically have to build concrete mixing plants on site! The look like a collection of huge round tank-style trailers tilted upright and assembled all together.

Edit - spelling.

Why is this? Does power interfere with the fiber?

Who are those competitors? The subject company is tho only one I know of like this. But I am not really active in the creative space so I'm ignorant.

I've been meaning to read that. How does it compare to Capital?

The new M-PAGES software by NGS is written in C++, with a bit of python tooling as well.

This is to replace the original PAGES software, which was written in Fortran. M-PAGES is able to process GNSS baselines using all the new satellite systems, as opposed to only GPS.

Edit - my understanding is they chose that language for good extensibility.

Not sure what exactly you mean by scan, but Land Surveyors use drone photogrammetry (and lidar when appropriate) to create TIN surface models of bare earth, yes.

But if it's a smaller area typically it's not worth using a drone and we'd use a terrestrial scanner like a Faro.

Edit - spelling.

2600 is still in print, but they did have some major distribution issues during COVID. I believe they have worked them all out by now.

They've been digitizing the collection as well, coming out the with annual digests.

If you still like paper a lifetime subscription is surprisingly reasonable. I subscribed about 20 years ago and have definitely gotten my money's worth.

What first piqued my interest in them was a watch and clock show in my town. I remember really thinking they were marvelous engineering, but I also remember that number of $1000 as an average for a working one.

However it's kinda iffy buying one that you can't actually test first. It's been too long since I've purchased anything on eBay so I don't know what the return policies are.

The guy at the show mentioned "always test the _one_ slider. Those go first"

Edit- spelling

Great article and great job on the software!

Do you know if there's any of these calculators still around and available to purchase? I've always wanted to get my hands on a curta but One of these would be awesome too.

>What I want to talk about here is how the type of behavior that makes us look smart in the moment (i.e. penny pinching) ends up not being smart in the long run.

Well said. I disagree with the article title, due to my experience with delivering pizza.

We all certainly knew the non-tippers. And they almost always were in the wealthiest neighborhoods. So once you go to a house 3 or 4 times, and get stiffed (or hear about it from the other drivers), they become your lowest priority.

Working class and poor neighborhoods almost always got better service and faster food delivery from us because we knew they tipped more often. The non tippers typically ended up with cold pizza and dropped 2 liters cause we didn't give a crap.
