Well, speak of the devil and he doth appear! :) I looked at PEP 708. I was confused by what "repository" means. In PEP 503 "A repository that implements the simple API is defined by its base URL .... Within a repository, the

Thank you. I don't think I was clear enough that the desire really doesn't match reality, in part because I'm not clear about that myself. I don't have a deep understanding of the new way of doing things, having only rea

There is a long-term goal to remove setup.py in favor of letting "a thousand flowers bloom". In modern Python setups, the pyproject.toml contains an entry for the 'build-backend'. There is a fall-back to 'setuptools

The first H-151 I built had a flaw. We went to the Heathkit store, about 45 minutes away, which provided the instructions for the fix. It was something like "scratch this trace off the circuit board and solder a wire between these two

I was at Illinois during 1992-1997. The school had a number of gopher services, and then ... poof, Mosaic. I think we set up our research group's http server in 1994. One of the PIs wanted to support both gopher and http, but by then t

In my field, cheminformatics, we refer to it as "Tanimoto similarity" because it was (quoting Wikipedia) "independently formulated again by T. Tanimoto." It's an odd set of linkages to get there. First, "Dr. Da

It's a tiny issue, but what I like least about the PNG format is the checksum at the end of each block. From what I gather, the checksum is there for two reasons: 1) a check on archival integrity, based on experience with its usefulnes
