beez | The framework for mobile browser faster development | Runtime Evironment library

I use Google Sheets to keep track of the release schedule for my blog. Each new year I create a sheet which keeps track of the date, content type, title, and a few other items.

A year or so ago I created a "dashboard" page which aggregated data across each sheet and tallied up the results by author and content type. This is really helpful when looking at the data as a whole, but I'd like to also just look at the data by a single year; how many reviews were published in 2019? How many videos did we release in 2020, etc.

I'd like to include a dynamic dropdown that I can change to only show results from the selected year, but that also includes an "all years" option as the default. Here's a sample of the data from one year:

I have a list of strings like:

beel beez baee beae

and I need to find the word (or its anagram) that is in common among all the words (if exist). In this case the magic word is:

bee

or its anagrams (ex: ebe, eeb)

My solution is:

I compare all the words between them:

I am using Python and I have a base64 string.

I want to know that if the base64 data I have received is a image and not any other file (eg. PDF, DOCX) whose extension is changed to image extension.

Example:

I'm trying to build an app that has music playing functionality. When the app is launched it shows the list of songs and when you click on it the song title shows but the song does not play. Please how do I fix this. Here's my music.java file
