Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Beej's Quick Guide to GDB (2009)
There is also GEF, which is widely used by the reverse engineering and CTF community.
-
How do you use gdb without the tui? Are there advantages? Or just describe your GDB workflow.
If you are on Linux, install GEF and be happy.
- TF2 on Linux is running incredibly poorly, reporting 1200%+ CPU usage. Steam also appears to have some sort of memleak and infinite loop/callback going on leading to absurd CPU usage over time.
-
Any good and easy-to-use C debuggers?
If you are in linux, I recomend none of them (haha) because you should get more used to GDB a little bit. You just need to install some good visualizers likes GEF, for example.

Are there any cpu emulators that could help me learn i386 assembly?

Fully Dockerized Linux kernel debugging environment
The attached debugger is not just raw GDB but is using https://hugsy.github.io/gef/ to make debugging less of a pain. It's still not perfect but helps plenty already.

Debugging with GDB
I still struggle with GDB but my excuse is that I seldom use it.
When I was studying reverse engineering though, I came across a really cool kit (which I've yet to find an alternative for lldb, which would be nice given: rust)
I'd recommend checking it out, if for no other reason than it makes a lot of things really obvious (like watching what value lives in which register).
LLDB's closest alternative to this is called Venom, but it's not the same at all. https://github.com/ovh/venom

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.

PicoCTF 2024- CanYouSee
❗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].

I think this can be deciphered using CyberChef...
