Benchmark: Core 2 Duo T7200 vs. Core i7 2620M

Test systems:
System 1: 2007 noteoobk: Toshiba U205-S5067: Core 2 Duo T7200, 4GB RAM, 320 GB HD
System 2: 2011 notebook: Toshiba R830-10P: Core i7 2620M, 8GB RAM, 256 GB SSD

This benchmark result is not only affected by the processor. Almost all system components affects the result. The processor is only the main component.

Results:
Evaluating overall performance, for compiling Linux Kernel and generate its RPM packages for Fedora 15: Core i7 system is 2.85 times faster than Core 2 Duo system.

Details
I've run the steps described on: http://kdpeter.blogspot.com/2011/05/steps-to-test-kernel-build-on-fedora-15.html, for the kernel package kernel-2.6.38.6-27.fc15.src.rpm.

The only difference to the procedure described above is that I added the command "time" in the building step, to be able to compare necessary time to do same task.
$ time rpmbuild -bb --with baseonly --without debuginfo --target=`uname -m` kernel.spec

Individual results
System 1: Core 2 Duo
real 67m48.453s
user 88m6.698s
sys 17m35.033s

System 2: Core i7
real 23m46.994s
user 68m25.556s
sys 10m29.816s

Toshiba R830 and 16GB of RAM

Image
The datasheet of Toshiba R830-10P mentions that the maximum memory capacity is 8GB. See it  here . But Intel says that the i7-2620M supports up to 16GB of RAM. See it here . I have asked for help on Toshiba Forums. Nothing useful from there. See it here . I was curious as I have a very particular need for 16GB of RAM. Today I decided to give it a try. I bought two Patriot PSD38G13332S (8GB PC3 - 10600 1333MHz CL9 SoDimm) and installed it on the notebook. It just worked. So if you have the need for 16GB of RAM and a similar notebook from Toshiba, you can install 16GB of RAM.

Five steps to create Fedora chroot jail using yum

Pre-Notes: - This will work only if your Linux Distro is based on RPM and YUM. I have tested it on Fedora but it may also work on RHEL and Centos... It will NOT work on Ubuntu, Debian, Suse... - The operating system and its version will be the same inside and outside the chroot jail. - On the example, the chroot will be placed at: /chroot/devel - To install different version of Fedora or other RPM based distro, it will be necessary to manage yum package repositories outside the jail. The five steps: # 1 - Create the chroot directory $ sudo mkdir -p /chroot/devel/var/lib/rpm # 2 - Initiate rpm db on chroot $ sudo rpm --root /chroot/devel --initdb # 3 - download Fedora Release package. # If you do not want Fedora, download the correct *-release package and use it # on step 4. There are examples on the references. $ yumdownloader --destdir=/tmp fedora-release # 4 - Install downloaded Fedora release inside chroot $ sudo rpm --root /chroot/devel -ivh /tmp/fedora-release*r

GitHub Social Coding

Github is simple to use and powerful git repository with great web interface. If your project is open source, there is no problem if your repository is also open, right? What could be better to open source projects than having free hosting on feature rich and reliable service? But if you are not the good guy and want to have your git repositories private, looks fair to charge you little money to keep your code safe.  This looks to be the basic business model do Github and the prices are attractive. For those have never being in touch with versioning and code repositories, Github is also good place to start. The step-by-step documentation will guide you over the process of using git. It is really easy to start. Github also encourages you to make friends and to grow your social network around the code you share. I would like to be your friend on GitHub, so you are invited to see my profile: https://github.com/petersenna If you are looking for a job, Github
