Linux implements the relevant features of a microkernel in its modularity.

>Linux implements the relevant features of a microkernel in its modularity.

Microkernels require less code to be run in the innermost, most trusted mode than monolithic kernels. This has many aspects, such as:

1 - Microkernels are more robust: if a non-kernel component crashes, it won't take the whole system with it. A buggy filesystem or device driver can crash a Linux system. Linux doesn't have any way to mitigate these problems other than coding practices and testing.

2 - Microkernels have a smaller trusted computing base. So even a malicious device driver or filesystem cannot take control of the whole system (for example a driver of dubious origin for your latest USB gadget wouldn't be able to read your hard disk).

3 - A consequence of the previous point is that ordinary users can load their own components that would be kernel components in a monolithic kernel.

there is pro & cons in both of them

1 - Monolithic kernel is much older than Microkernel. It’s used in Unix . while Idea of microkernel appeared at the end of the 1980's.
2 - the example of os having the Monolithic kernels are UNIX , LINUX while the os having Microkernel are QNX , L4 , HURD , initially Mach (not mac os x) later it will converted into hybrid kernel , even MINIX is not pure kernel because device driver are compiled as part of the kernel .
3 - Monolithic kernel are faster than microkernel . while The first microkernel Mach is 50% slower than Monolithic kernel while later version like L4 only 2% or 4% slower than the Monolithic kernel.
4 - Monolithic kernel generally are bulky . while Pure monolithic kernel has to be small in size even fit in s into processor first level cache (first generation microkernel).
5 - in the Monolithic kernel device driver reside in the kernel space . while In the Microkernel device driver reside in the user space.
6 - since the device driver reside in the kernel space it make monolithic kernel less secure than microkernel . (Failure in the driver may lead to crash) while Microkernels are more secure than the monolithic kernel hence used in some military devices.
7 - Monolithic kernels use signals and sockets to ensure IPC while microkernel approach uses message queues . 1 gen of microkernel poorly implemented IPC so were slow on context switches.
8 - adding new feature to a monolithic system means recompiling the whole kernel while You can add new feature or patches without recompiling.

More believable than "suddenly /g/ is playing videogames". We all know it's you vtard flock marketers.

this is bait, right? i mean, chrome is shit, but ie is even worse.

>>59338741
Isn't this obvious?

Not bait, just the truth.
Chrome can play webms, that's the ONLY good thing about that browser.

mmh let me think. How about you buy a MBP?!?!?!?!!?!?!

Hows that even a question? Buy a 2015 MBP and you are golden my dude.

Basically this, and I'm not even memeing. What you need is a good display/accurate colors and those are hard as fuck to come by on laptops. Next best bet would be a XPS 13 or 15.

Runs over CIA niggers

>>59337888

probably rants to his parents about CIA niggers

goes to buy food with the social worker assigned to his family in desperate need. They might pay a housekeeper to take care of some basic needs because all of them are basically disabled people and his father worked on rockets so they probably have some vault full of money stashed away randomly. Like old people do.

Then he jerks off while shitting himself (he admitted to it). Probably watches some TV and doesnt really understand that the TV is not talking to him.

Then he goes back to streaming and does his usual routine.

Quite a life i must say.

Yes.

Yes, I only buy premium Intel products for professionals. AMD and Nvidia are companies that make cheap products aimed at video gamers.

They're bound to last longer when they're not powerful enough to overheat.
