YouTube: Google has found a way to break Invidious
A parameter was changed from '2AMBCgIQBg' to 'CgIIAdgDAQ%3D%3D' which is just the correct base64 encoding they should have been using the entire time.
I don't think this was a hostile action by Google, I think someone just added better input validation for security reasons and it accidently broke the bad requests they were sending.

❗This is indeed the flag, but the text is encrypted with Base64. Usually, the presence of padding character "=" indicates that's Base64 type of encoding (but that's only one of the hints). To decrypt it, we can use CyberChef. Copy-paste the text and we either:

CyberChef from GCHQ: The Cyber Swiss Army Knife
It uses a combination of magic bytes (like the `file` command), entropy analysis and character frequency detection to determine whether an output is likely to be of interest to the user.
The file type mechanism is written here[0]. There's a list of all signatures we detect here[1].

[2023 Day 2] [Python] Stuck on the first task
If you are going to use RE's, use something like https://regexr.com/ to double check that they're doing what you want. I was suspicious of your 'cols = re.findall(r'\d+ .....', i)' line, and indeed it does miss some columns. You should rethink your column detection, and either not use REs or learn how to use capture groups and \w. There would then be no reason to use yet another RE in your column iterator to extract the numbers which you've already detected.

2023 Day 2 Part A [Java] regex pattern not matching
First time posting here, let me know if I need to edit post to conform to any rules. My issue is that I'm trying to match regex pattern to separate out the number of cubes drawn and its color but my Matcher object seems to not be returning any matches so it's throwing a no match found exception when I try to call digitMatcher.group(). I have tested my regex pattern on sites like regexr and it seems to pass there but it's not working for some reason here. I use the same type of regex on day one and it work there so I'm not sure where my regex pattern is failing here. I'm talking about specifically in my isGameValid() method where I create a matcher base on a pattern I made above. Through debugging I know that I separated the string color pairing correctly and that my Matcher object has the correct regex pattern, it's just not matching for some reason. Any help would be appreciated. Code below:
