Why can't radio buttons be “readonly”?
I would like to show a radio button, have its value submitted, but depending on the circumstances, have it not editable. Disabled doesn't work, because it doesn't submit the value (or does it?), and it grays out the radio button. Read-only is really what I'm looking for, but for some mysterious reas...
Understanding __get__ and __set__ and Python descriptors
...ly implements __get__, __set__, etc. and is then added to another class in its definition (as you did above with the Temperature class). For example:

You can use cut to access the second field:
cut -f2
Edit:
Sorry, didn't realise that SVN doesn't use tabs in its output, so that's a bit useless. You can tailor cut to the output but it's a bit fragile - something like cut -c 10- would work, but the exact value will depend on y...

...ript/TypeScript class instance. There are a number of techniques for doing it, and generally involve copying data. Unless you create an instance of the class, it won't have any methods or properties. It will remain a simple JavaScript object.

Detect if an input has text in it using CSS — on a page I am visiting and do not control?
Is there a way to detect whether or not an input has text in it via CSS? I've tried using the :empty pseudo-class, and I've tried using [value=""] , neither of which worked. I can't seem to find a single solution to this.

How does a hash table work?
...xplanation in layman's terms.
Let's assume you want to fill up a library with books and not just stuff them in there, but you want to be able to easily find them again when you need them.

Getting an element from a Set
...
