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.

this is might be a stupid question but when i opened the my pc the monitor shows dell logo even thought mmy monitor is lLG (m desktop is dell) does that mean if i had a Lenovo desktop for example my monitor will show Lenovo logo when i opened my pc?
You can change the image with HackBGRT

Found out my Motherboard supports custom boot logos!
This exists and will work to replace the windows logo if you guys want to use it https://github.com/Metabolix/HackBGRT. Should work on all motherboards and laptops.

Is it okay to turn off BitLocker in win 10
I was just tryna modify boot logo with HackBGRT (https://github.com/Metabolix/HackBGRT/releases) . Boot is okay , logo is changed ,, not the one I wanted, but in the process I had to turn off secure boot for that. Yes, bit locker was on as by default but turning off secure boot made me write the recovery code on every boot,

Someone can help me?
I do not have much experience with this type of thing, but I'd check the bios if accessible, because it's sometimes as simple as an option that must be switched. If this doesn't work, I know that some companies make special software to reset the logos for specific models. It might also be worth investigating this page (https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/boot-screen-components), which is about the BGRT, or this page (https://github.com/Metabolix/HackBGRT) a program that could fix this, but might also brick your computer.

Simos18 Supplier Bootloader (SBOOT) Exploit: Reading Boot Passwords
In addition to the RSA signature, all Simos18 code blocks are also checked against a simple CRC checksum. And, in this case, SBOOT tries to validate the CRC checksum before it validates the RSA signature. It turns out the CRC validation is performed using an address header, and the address header has weak bounds checking. So, we can ask the ECU to checksum the boot passwords, and send us the checksum back. Since CRC is not a cryptographic hash (it is reversible), we can use the CRC values to back-calculate the boot passwords. Unfortunately, we can't do this cleanly, because the high side of the address range IS correctly bounds-checked. So instead, we have to start the CRC checksum process, then rapidly reboot into the Tricore Bootstrap Loader and dump the contents of RAM, to see the intermediate/temporary CRC values that have been calculated for only the boot passwords. https://github.com/bri3d/TC1791_CAN_BSL/blob/main/bootloader.py#L113
