Python Version Support Ideas

As a general rule, I don't like to just stop supporting Python releases just for the sake of deprecation. I try to be relatively wide in the set of Python's I'll support for my libraries, with my current general rule being 2.7, 3.6+ .

Why those? Well, 2.7 is still on RHEL/Centos for another year ...

Cleaning up the PyOpenGL Demos

Spent a bit of my second-last-day-of-vacation cleaning up the PyOpenGL Demos so that they run with current Python 3.10, PyOpenGL, numpy and PIL and can be installed as a package rather than only being usable via a git checkout.

There were a few bits of bit-rot, mostly around ctypes no longer allowing you to raise ...

What's with the bot fodder on planet python?

It seems that someone has created a script to generate posts of the form "ModuleNotFoundError..." with a generic "so install the package" article body. I can only imagine this is to get Google ranking. But why is it on planet python? It's a hell of a lot of spam when almost everyone following planet python ...

Go Lang Impressions after 2 Months

So for work I've needed to learn GoLang, which I'd always before picked up, kicked the tires and said "meh" on. A few months now of working with it pretty-much-daily have upped the "meh" quite a bit. To be clear, I'd choose Go over raw C, but I'd likely pick modern C++ over Go.

Channels ...

Social Cost of Carbon and Ethics

It is unreasonably frustrating to me that discussions of the Social Cost of Carbon by Economists are seemingly using models that read like a Libertarian's Fancy Footwork to Excuse Desired Behaviour. Basically, by deciding that we value the lives of our children and children's children less than our own comfort, we can deprecate the loss-in-value ...

Django Field Rename Migrations and Test Cases

Is there some trick to running Django test cases when you've got a RenameField later in the migration-stack? I feel like this has to be some obvious thing I'm missing...

With a migration (say 0058_big_restructure.py) which does this:


migrations.RenameField(
model_name='rfsource',
old_name='source_name',
new_name='follow_source_name',
),

and a previous migration, (say 0006_long_ago_change_that_populates_some_other_field.py) which doesn't explicitly reference the source_name ...

Seems Time Warps have Infected the Blog

Just randomly clicked through a similar posts link and found an article that was (actually) published in 2015 claiming to be published in 2020. Clicking through more random links, it seems that every article that existed when I moved the blog to the new service on May 18th of last year got the timestamps modified ...

PycraftServer Plugin

So the boys (and their cousin) are both into Minecraft again, so I've been refining the Pycraft code quite a bit. We no longer use the RaspberryJuice plugin, but instead have a custom Bukkit plugin that does Java reflection/introspection to auto-generate the API. That lets us do a lot more, manipulate inventories, read and write ...

Adding a Certificate Authority to Chrome Trust Store

So you have a corporate or project specific root of trust you need Chrome to recognise. How do you take your PEM certificate as you get from easy-rsa or the like and make it something that Chrome will accept? The answer is not particularly complex, but it really seems like this very-common process is not ...
