Sometimes there is need for the software analyzers to benchmark the software operation on different hardware platforms. Software benchmarking is especially useful when analysis of software execution on grid platforms is performed. The level of diversity of the grid resources can be considerably influential on the execution time and overall efficiency of the grid application.
By default, the Linux kernels do not perform counting on many events associated with application execution (L2 cache misses, FLOPS counting etc.). Therefore, in order to be able to do application benchmarking, a special patch must be implemented in a fresh kernel source. Additionally, after the kernel source is patched, it must be recompiled and activated.

This kind of compiler error happens when an integer is too large to be stored in a single 32-bit register. A common situation is when a user is compiling 64-bit optimized code on a 32-bit machine. Therefore, one register of the 64-bit machine has size of two registers of a 32-bit machine. So, in order to compile integer that long, the user has to inform the processor that the integer has to be stored on two 32-bit registers (all together, 64 bits).
Commonly, the type of the integer can be changed to “long long int”
Example:
long long int var = 10000000000;
Another option is specifying the type using the suffix LL.
int var = 10000000000LL;
There are other suffixes available. For instance, if the variable is unsigned (cannot contain negative values,but can store values of larger magnitude than the signed type), you can safely use the suffix LLU.
Example:
int var = 10000000000LLU;
The hardships of installing new software on Linux. Despite our enthusiasm, we must admit, we have all experienced them. Missing dependencies, strange compiling errors, old versions of installed packages … Is this the problem number one on the road to complete Linux globalization? Small debate might be adequate.
The time when UNIX-like systems were a privilege to the geek and hi-techie community is long gone. We have seen package management systems, graphic installers, improved GUI interface and so many other novelties. If we simply ask ourselves why all this has been done, the most reasonable answer would be – reach to more users and make the Linux more user-friendly. Therefore, we can easily conclude that the Linux OS has set its path to something that its most fierce counterpart, Windows, has it for a long time – acceptance of the masses, people of all technical background profiles.

This guide explains how to install Moodle for the first time. There are links to other pages that go into more detail and try to cover the majority of possible web server setups.
Secondly, you may want to consider reviewing Finding and Selecting A Web Host to consider whether you really want to install Moodle yourself. If you decide to move forward with an installation, please read all the installation documentation carefully. Thirdly, if you still have a problem for which you can’t find the answer, please see the Using Moodle Installation problems forum where there are many people who can help you.

I decided post this note because it seems to me something about We should taking care always for our protection server.
Im refering about missing “x” encripted password in our file: /etc/passwd
We going to analyze the line code for users into GNU/Linux. The main goal that We need to know about its over this file, What it is ? ..

We have chosen Linux that is the most widely used server technology to host our websites and web applications.
And of it’s a natural choice because we built applications based on PHP and MySQL. A company that use ASP would naturally go with a Microsoft server (IIS for example). But most PHP based applications use Linux as a server, since it’s more affordable (Linux is free) and has proven over the years its reliability.
Some example of our products can be seen on: yougapi.com/demo
Of course today we can host PHP on Microsoft server, but it’s more costy and we are not sure if the MySQL database plateform can be hosted on a Microsoft server.
This is our first post on Linux.edu and hope to come back to you soon with other articles talking about some technologies or programming techniques we are working on.
