Post date: September 21, 2009, 16:09 Category: Benchmarks Views: 4877 Comments
Tutorial quote: Gnome Shell consists of two big parts: the panel and overlay. The panel part is pretty much obvious - system tray, user name, and clock stuff and the activities button which activates the overlay -, and about the "overlay", well, take a look at this screenshot:


Basically, it allows the user to concentrate on switching to a new activity by opening new applications, documents, or both. It displays all the current user workspaces and open windows and facilitates organizing them.

So far, the Gnome Shell installation was quite time-consuming, so most people didn't try it until now. With time, however, this has changed, and you can install it by running a script. Here is how:

Optimizing C/C++ programs using the GProf profiler

Post date: May 24, 2005, 18:05 Category: Optimizing Views: 8075 Comments
Tutorial quote: One of the most important things to keep in mind while optimizing an application is: optimize where it counts. It is no use to spend hours optimizing a piece of code that usually runs for only 0.04 seconds anyway.

GProf provides a surprisingly easy way to profile your C/C++ application and spot the interesting pieces right away. A small case study shows how GProf was used to reduce the running time of a real-world application from over 3 minutes to under 5 seconds, by identifying 2 data structures as important and optimizing those.

Historically, the program goes back as far as 1982, when it was introduced on the the SIGPLAN Symposium on Compiler Construction. It is now a standard tool available on virtually all flavors of UNIX.
