Jockey | music player for Android | Music Player library

EDIT - Answer as below with the extra code new_df = df_hist[msk]

I'm trying to remove all rows from a DataFrame where the date ('RaceDate') is over 2 years ago. I convert the 'RaceDate' using pd.to_datetime - this gives the format e.g. 2018-09-01. I use datetime.datetime.now().date() and this gives the format datetime.date(2022, 2, 10)

I can't work out how to check the difference is over two years as the code gives me Key error. Any help would be most welcome.

I am working on a project under NodeJS that uses ES6 imports/exports (hence having set type: module in its package.json) and want to automate some tasks using Grunt. Now, I absolutely love grunt, but it appears to me that even in 2022 it is still not able to work nicely with ES6 modules? I always get an error saying "require() of ES Module /vagrant/Gruntfile.js from /vagrant/node_modules/grunt/lib/grunt/task.js not supported."

I understand where this is coming from, and I do understand there are workaround options - in particular, renaming Gruntfile.js to Gruntfile.cjs and passing it to grunt with the --gruntfile command line option. But that is incredibly annoying - it makes the command six times as long as it would be if I could just run grunt and be done with it. Pretty much the same goes for transpiling with something like Babel: That is exactly the kind of thing grunt is intended to handle in the first place, so it feels a bit like the horse riding the jockey. I feel like this should "just work".

Am I missing something here, or is grunt really unable to handle ES6 imports out of the box?

The player has a progress bar. I use the trackProgress computed property to update the progress in real-time:

I have made the vinyl spin with the help of a CSS keyframes-based animation and the isSpinning computed property.

I want the vinyl to stop spinning once the end of the current track is reached, which is why isSpinning has this "formula":

This is a variation of this question, only with a new column, Track:

Any ideas on how to do it?

I am trying to get data from the following script. I have divided the XPath into 02 parts in the parse function. 1st part contains the fixed data which I don't want to loop and the 2nd part contains a table which I want to loop. When I ran the script, it only gives the 2nd part data. I have used Splash to render the HTML.
