      My first semester CS professor is an asshole and downright condescending. By the 2nd semester, the size of the class is halved. I am pretty sure it's because most changed their major because the that horrid professor literally killed their passion for the subject.

    The kernel is the central module of an operating system (OS). It is the part of the operating system that loads first, and it remains in main memory. Because it stays in memory, it is important for the kernel to be as small as possible while still providing all the essential services required by other parts of the operating system and applications. The kernel code is usually loaded into a protected area of memory to prevent it from being overwritten by programs or other parts of the operating system.

    I don't normally comment but this deserves a 9.5 /10. The detractor being some of the graphic presentations flashed too fast when Gary was speaking and these are invaluable to blended learners.
    However, this is a very important topic when undertaking the Certified Secure Software Lifecycle Professional Exam.

      Kernel is important! BIOS is much more important. Even in Android Developers program got to have a access to the hardware in order to build a kernel. Kernel's are much more simple in Android with for fewer cell phones than Desktop or laptop computers. Not as many devices to connect as in Linux. Of course a college professor isn't probably going to be able to build a kernel, because there more worried about security, networking, viruses, ssh, telnet and just overall repair and upkeep of the hardware on the floor. Other factor Gary forgot to explain is after 1 year or less most of these great ideas are turned into an app available on the Android Store.

  • @worldhello1234
    @worldhello1234 5 років тому

    Gary, you are the man, man. You cannot stress enough that you absolutely need root access to properly install a custom kernel. That saves people a lot of headache if they try to find a definitive answer whether or not you need root access to install a different kernel.
    My conclusion, custom rooms can be flashed via custom recovery which only requires an unlocked bootloader because it is basically end user stuff.
