Julien Tinnes describes the new sandbox mechanism for the Chrome browser under Linux.
Hi,
I have recently started looking for a laptop. However, it came to my attention that modern graphics cards have a mechanism allowing the operating system to swap between the built in card and the more powerful one, depending on the needs of the user (NVIDIA calls it optimus). Furthermore, I understand that this mechanism is not supported on linux. Is this true?
Google Chrome, a browser built on the WebKit layout engine that aims to be minimalistic and versatile at the same time, is now at version 24.0.1312.32.
This latest version of Google Chrome brings improvements, but it also introduces a fix for an annoying scrolling issue.
Highlights of Google Chrome 24.0.1312.32:
• The Chromoting client plugin has been restricted and extensions & apps can'
In Linux in older versions the user calls were routed to their corresponding system calls through interrupt 80 which was handled by system_call().
I mean say for the user mode function read() there was a corresponding kernel mode function.
The system call index was fed in eax register and was used to index into system call table to find the corresponding kernel mode function.
But in newer lin
Google proudly announced last evening, July 31st, the stable release of the Google Chrome 21 web browser for Linux, Macintosh, Windows and Chrome Frame platforms.

I was scanning one of my friends servers using nmap and got these port details.
When one process sends a signal to another process, does receiving process waits until the scheduler schedules it? So if the scheduler reschedules about 1000 times per second, is the latency from generating the signal to delivery of the signal about 0.5 ms? Suppose we only have two processes.
And more generally, how is signals mechanism implemented in Linux?
Chrome will soon warn users when they are about to download software that could try to change how the browser handles extensions. Specifically, this extension to the company’s Safe Browsing system looks for binaries that could allow potentially malicious extensions to be installed in the browser without the user’s knowledge.
I'm doing two system calls (linux 3.2). I've created these two system calls, and I have compiled the kernel. These two system calls need to write and read on a file. I'll modify two system calls, read and write to read this file. So this file need to be accessible for these four system calls (read, write and my two system calls).
