Change Ctrl + Alt + Delete Behavior To Open System Monitor, in Linux

Post date: September 24, 2009, 12:09 Category: Miscellaneous Views: 2621 Comments
Tutorial quote: Actually, I've written this post before (quite a few months ago) but then deleted it because it didn't work. In the mean time, I found out why, so I decided to post it again. I find pressing Control + Alt + Delete to open up System Monitor to be very useful, especially for Windows users who are used to it and may actually press this quite a few times before realizing it doesn't do anything or what it does in Windows. Using System Monitor, you can preview all running processes, end or kill them, see how much CPU a process is using, CPU + memory + network history, available disk space and even change how much CPU a process should use.

There are 2 ways of changing Ctrl + Alt + Delete behavior to open System Monitor: one if you are running Compiz, and one for Metacity, only to use if you are not running Compiz.

Tutorial quote: Kernel 2.6.28 Released

Torvald released the final version of Linux Kernel 2.6.28. It's not a big change since RC 9, but it finally appeared as final after lots of discussion on LKML whether to postpone the release or release earlier and make the merge window longer as the developers goes on long holidays.

Here's some summary of Kernel 2.6.28 (taken from KernelNewbies): Linux 2.6.28 adds the first version of Ext4 as a stable filesystem, the much-expected GPU memory manager which will be the foundation of a renewed graphic stack, support for Ultra Wide Band (Wireless USB, UWB-IP), memory management scalability and performance improvements, a boot tracer, disk shock protection, the phonet network protocol, support of SSD discard requests, transparent proxy support, several new network drivers, controlable IO CPU affinity, high-resolution poll()/select(), support of a minimal "dummy" policy in SELinux, tracing improvements, x86 x2APIC support, a fb driver for VIA UniChrome devices, Mitac Mio A701 ARM-based smartphone support, some new drivers, improved device support, and many other small improvements and fixes.

The Linux /proc Filesystem as a Programmers' Tool

Post date: June 22, 2005, 09:06 Category: Programming Views: 3908 Comments
Tutorial quote: My entry into systems programming was guided by my desire to understand further the operating systems I was working with daily as a contract UNIX and, later, Linux system administrator. The result of this was ifchk, a packet sniffer detector I wrote in C and released in June of 2003. ifchk initially was written under IRIX and then ported to Linux, mostly under the 2.4 kernel. The current ifchk revision, beta 4, recently was released and beta 5 is on the way.

My work on ifchk has allowed me to examine programmatically several areas of operating system functionality. Examples include the Linux netlink(7) and rtnetlink(7) facilities, device control--that is, network interfaces--via ioctl(2), signals and proc, the process filesystem. Proc and its ability to display a wide array of data concerning the runtime state of a system are the focus of our discussion here.
