Yes, exactly that .. I replied from different account and my email was rejected. Just make sure that your mysql is actually running. Depending on your OS, run netstat -an | grep 3306 and this will tell you whether socket is actually in listening mode or not. If it's not, your mysql is either no

Re: Parallel(?) programming with python

Queues are better than lists for concurrency. If you get the right kind, they have implicit locking, making your code simpler and more robust at the same time. CPython threading is mediocre for software systems that have one or more CPU-bound threads, and your FFT might be CPU-bound. Rather than

Dictionary order?

Hi folks. I'm still porting some code from Python 2.7 to 3.10. As part of that, I saw a list being extended with a dict.values(), and thought perhaps it wasn't ordered as intended on Python 2.7, even though the problem would conceivably just disappear on 3.10. So I decided to write a little test

Re: Extract the space group generators from Bilbao Crystallographic Server.

It's good to include what you want to see as output, but it's important to also include what you have as input. It's also good to include what you've coded so far. It's considered good etiquette to give it a try yourself before asking the list. On Thu, Jul 14, 2022 at 1:03 PM hongy...@gmail.com

Re: Question about building Python-3.9.12 on OpenBSD 7.1

It's been my understanding that there is a fundamental difference between the *BSD's and the Linuxes. The *BSD's have their ports system, that collects deltas against third-party packages to build them on a *BSD. These deltas become part of the ports system. The Linuxes port an application, and

Mypy alternatives

Hello people. I've used Mypy and liked it in combination with MonkeyType. I've heard there are alternatives to Mypy that are faster, and I'm looking at using something like this on a 457,000 line project. Are there equivalents to MonkeyType that will work with these alternatives to Mypy? And ha

Hi folks. I heard there's a Windows-like "py" command for Linux (and Mac?). I'm finally getting to porting a particular project's Python 2.7 code to 3.x, and one of the first steps will probably be changing a lot of "python2 script.py" to use #!/usr/bin/env python2 and chmod +x. Then we can upda
