Ken Kramer's About San Diego | Pacific Beach & University Heights street names | Season 1 A story about the street names in Pacific Beach and University Heights.

It's a small thing - but after 50 years of living in/visiting Pacific Beach, only this week did I learn why Missouri St is the outlier (Garnet, Diamond, Opal, Emerald, etc). Thx to watch.sdpb.org/video/ken-kr...

I was forced to teach on a windows machine in Germany. Whenever I tried to do something I could not understand I had a student come help me…

Although outdated, one thing that GNSS geodesists should be thanked for was designing a receiver-independent data format early on. I never realized how important that was until I worked with in situ soil moisture data ...

I wouldn't even use the word design - academics don't like them either, but government agencies that should push for modernization decline to do so. The file formats are not only ancient but were designed way way way before real-time streaming was possible.

I’m afraid I would not be able to install and operate these GNSS systems anymore.

I can think of at least one NAS member who had an award taken away by a prof. organization. Since there is no public report, it is as if it never happened. 2/2

I only know the NAS process, and it completely off-loads misconduct assessments to other institutions (i.e. if NSF or your home institution found you guilty of misconduct and there is a public document). 1/2

Yeap, GPS is a big part of the way we know what time it is. And that includes your ATM, at some level.

Surveyors also need access to high precision GPS. I am not sure the military even has an off switch for the lower precision GPS signals used by cell phones.

If they tried to run GPS as a military only system, they will feel the immediate wrath of American farmers. They are a huge market of GPS users.

I can’t see how they can turn off GPS unless they decide they don’t want American satellites, vehicles, airplanes, and ships to know where they are.

Another problem with open source (in geodesy and earth science) is maintaining and documenting it. If you have simple code that you never change, then ok. But if you have a large package and endeavor to improve it, even keeping the documentation up to date is a lot of work.

There are more ways to help with documenting contributions now (e.g. DOI for datasets and code), but to be honest, most users don't pay attention to "please cite this repository." And if I were still being evaluated by my former employer, my open source work would be ignored.

And so agree πŸ’― about too many papers. It is a normal academic thing to produce but making products and code available also important.

This would be considered a plus at CU.
