I recently hosted an episode of Software Engineering Radio called "Jennings Anderson and Amy Rose on Overture Maps"!

🚀 Hi! I'm a researcher, teacher, podcaster, and software developer!

Innovating in technical areas such as software engineering and software testing, I teach courses, conduct research, write papers and a blog, give presentations, create software, and serve organizations. Working as an Associate Professor in the Department of Computer and Information Science at Allegheny College, I am an associate editor for the Journal of Software: Evolution and Process, an academic editor for the PeerJ Computer Science journal, a program committee member for conferences like the International Conference on Software Testing, Verification and Validation and the International Conference on Software Engineering, and a reviewer for journals like Transactions on Software Engineering and the Journal of Software Testing, Verification and Reliability. Along with media appearances on podcasts like Stack Overflow and Talk Python, I interview the world’s leading experts on software engineering as a co-host of Software Engineering Radio. You can learn more about me and my work by reading my biography, downloading my curriculum vitae, and subscribing to my mailing list.

My AI debugging pattern:

Isolate the problem
Share relevant code + expected behavior
Test suggested solutions
Iterate on edge cases
Document the fix

The best part? I learned why it broke, not just how to fix it. This helps with future debugging.

Wow, *two* big outages today, in the top web frontend (CloudFlare, in front of about 25% of sites), and the top git forge (github, with something like 97% of public git repositories).

Stuff like this is why I built arewedecentralizedyet.online/ to keep an eye on how centralized some of the services we rely on are.

Thanks all for the discussion in this thread.

To summarize, was puzzles me is the difference in behaviour of `cd ..` compared to `ls ..` when symlinks are involved, both in Linux and MacOS Unix (tested with `bash`).

It is reassuring that we get the same behaviour with both, but it is also rather odd that we get inconsistent behaviour for `ls` and `cd` regarding the meaning of `..` when symlinks are involved.

Of course, all of this goes back to the early 1970's.

I don't complain. I was just puzzled when this happened to me.

It is so nice that the rather old Unix is still available, in macOS, and with a newer incarnation as Linux.

I hate Windows so much, and luckily I don't have to deal with it.
