I've been using Anki for years. Anki has recently changed its version numbers to year.month. From version 23.10, FSRS algorithm is implemented for scheduling reviews. Without thinking too much, I upgraded to the latest version.

Not surprisingly, this upgrade broke a few addons on my computer:

Fixing them was easier than I had thought.

When you start Anki, you are greeted with this alert if there's a bug in an addon. ⋯

Here are a few things I noticed in week 7.

I was creating a React app using create-react-app and ran into this error:

After googling around I saw a workaround by installing v5 locally.

Yet a better workaround is: ⋯

The more I program, the more I find myself realizing the why of some of the basics.

You can use either a method or a function to sort or reverse a list in Python. One works in-place, meaning the order of items in the original list is changed. The other works on a copy of the list and returns an ordered version of that copy as a new list.

list.sort() and list.reverse() are methods of the list class. They are both verbs, suggesting they take actions on an instance of the list class. And as methods that are internal to a list, they are understandably “allowed” to change the internal order of list items.

sorted() and reversed() are functions external to the list class. They are both adjectives. If a function tampers with the data passed in as an argument, that makes it not a pure function. So in functional programming terms, they are both pure functions.

A few things:

Handling date and time is more complicated than I expected. python-dateutil is quite helpful when you need to parse a datetime string.

I tried updating a field in a MongoDB document using MongoEngine. The value of that field was an embedded document that contained four sub-fields. I intended to change the value of subkey2. But the entire embedded document was overwritten.

I'm quite glad I caught this potential bug early on. And indeed, smart people out there have figured it out. ⋯
