The Steam give a kick to the other distros.

The Steam development team give a kick to the other distros.

After I try to put steam on Fedora without results , the team replay:

Hello Catalin,

Thank you for contacting Steam Support.

Steam for Linux is currently only supported on Ubuntu 12.04/12.10 with Unity, Gnome, or KDE desktops.

If you are running another distribution of Linux, we will not be able to provide support. We recommend you install Ubuntu for the best Steam experience on Linux.

About Google and Sets Live

This is old feature I liked ...

Google comes with other this feature named Sets Live since 2008.

Based on an idea to be able to recognize the similarity of a set of terms.

It's worked on spreadsheet and is very simple.

Just fill with two words in the spreadsheet, select with key SHIFT (highlight the two cells).

Press CTRL key and dragging the small blue box and google will automatically identify other similar terms.

Also seam Google continues to work on expanding their use of semantic information.

News: Intel and TV service ?

According to Mr.Huggers, Intel wants its internet TV service to incorporate, including live programming, on-demand content, catch-up TV, and apps.
This can be good but can be also an easy way to take some new clients.
The big problem is " What will see in this service?".
I don't expect to see something about the secrets of Intel assembly code or development team, but can be something nice.

GNOME Developer Experience Hackfest 2013

This week I’m attending the Developer Experience hackfest in Brussels.
This week Red Hat and the GNOME Foundation giving you the chance to attend the Developer Experience hackfest in Brussels.
The goal of the hackfest is to improve the overall application developer experience.
There are three main areas of work we suggest for this hackfest:

• Tooling (Anjuta, Monodevelop, application bundling, intltool, gtk-doc, autofoo and friends...)
• Developer docs and mindshare (unified online/offline API reference UI, app developer community building...)
• Further platform needs (improvement of data-driven apps and other needs with an unclear answer)
• Application bundling and sandboxing, the application as the first class concept in the kernel

The linux command: dmidecode

The linux command dmidecode is a tool for dumping a computer's DMI.

# dmidecode -h
Usage: dmidecode [OPTIONS]
Options are:
 -d, --dev-mem FILE     Read memory from device FILE (default: /dev/mem)
 -h, --help             Display this help text and exit
 -q, --quiet            Less verbose output

Vulnerability? google paypal facebook and internal ip

Do you have any idea about an Internal IP Address or a Private IP Address that too assigned for Multinational Companies? Yeah, today we are gonna discuss about Internal IP or Private IP address Disclosure.
Disclosure of an Internal IP like 192.168.*.* or 172.16.*.* , can really Impact? Most security researchers call it as "bull shit" vulnerability. But when it comes to impact calculation even if the server is behind a firewall or NAT, an attacker can see internal IP of the remote host and this may be used to further attacks.

Linux - Fedora and Android make read-only file system.

I don't know what is the problem with Linux - Fedora and Android OS.
After I put my USB cable seam Fedora make from write disk to read-only.
Maybe the Android when scan the device set to read-only.
So you can get some error like this when you use the chown command:

chown: changing ownership of ...: Read-only file system

That can be one big problem when you want to copy files on your tablet.
I found a solution, just use remount.

# mount -o rw,remount /media/disk

If you want to make read-only, use:

# mount -o ro,remount /media/disk

That will solve this issue.

News: Tips and tricks: recursive show images

The "Mastering OpenCV with Practical Computer Vision Projects" book is done and published!
Also: including a screenshot of each project...
This will be the main issue.
... to see the screenshot from each project
...and also to find a way for any file to use
Let's take the book and source code:

$ git clone git://github.com/MasteringOpenCV/code.git

Go to the main folder: $ cd code and use this:

code]$ ls 
Chapter1_AndroidCartoonifier     Chapter7_HeadPoseEstimation
Chapter2_iPhoneAR                Chapter8_FaceRecognition
Chapter3_MarkerlessAR            Chapter9_FluidInteractionUsingKinect
Chapter4_StructureFromMotion     LICENSE.txt
Chapter5_NumberPlateRecognition  README.md
Chapter6_NonRigidFaceTracking

If we use the tree Linux command the result will be:

.
|-- Chapter1_AndroidCartoonifier
|   |-- Cartoonifier_Android
|   |   |-- AndroidManifest.xml
|   |   |-- jni
|   |   |   |-- Android.mk
|   |   |   |-- Application.mk
|   |   |   `-- jni_part.cpp
|   |   |-- project.properties
|   |   |-- res
|   |   |   |-- drawable

|   |               |-- CartoonifierView.java
|   |               `-- CartoonifierViewBase.java

|   |   |-- cartoon.h
|   |   `-- main_desktop.cpp
|   |-- README.txt
|   `-- screenshot.png
|-- Chapter2_iPhoneAR

We need something to find the absolute path and give that to gthumb to run it.
First, find the screenshot:

 code]$ ls -d  $PWD/**/*.png
/home/free-tutorials/code/Chapter1_AndroidCartoonifier/screenshot.png
/home/free-tutorials/code/Chapter2_iPhoneAR/screenshot.png
/home/free-tutorials/code/Chapter3_MarkerlessAR/screenshot.png
/home/free-tutorials/code/Chapter4_StructureFromMotion/screenshot.png
/home/free-tutorials/code/Chapter5_NumberPlateRecognition/screenshot.png
/home/free-tutorials/code/Chapter6_NonRigidFaceTracking/screenshot.png
/home/free-tutorials/code/Chapter7_HeadPoseEstimation/screenshot.png
/home/free-tutorials/code/Chapter8_FaceRecognition/screenshot.png
/home/free-tutorials/code/Chapter9_FluidInteractionUsingKinect/screenshot.png

Now will run gthumb with all these images:

code]$ ls -d  $PWD/**/*.png | xargs gthumb 

ImageMagick resize with preserve aspect ratio.

ImageMagick is used to change images.
In this case, I will show how to resize images and preserve aspect ratio:
...with height: 600 pixels

convert  -resize x600 *.png

...with width: 600 pixels

convert  -resize 600x *.png

Linus Torvalds - kernel 3.7 is now out.

From: Linus Torvalds <torvalds <at> linux-foundation.org>

Subject: Linux 3.7

Newsgroups: gmane.linux.kernel

Date: 2012-12-11 03:59:50 GMT (9 hours and 45 minutes ago)

Whee. After an extra rc release, 3.7 is now out. After a few more trials at fixing things, in the end we ended up reverting the kswapd changes that caused problems. And with the extra rc, I had decided to risk doing the buffer.c cleanups that would otherwise have just been marked for stable during the next merge window, and had enough time to fix a few problems that people found there too. There's also a fix for a SCSI driver bug that was exposed by the last-minute workqueue fixes in rc8. Other than that, there's a few networking fixes, and some trivial fixes for sparc and MIPS. Anyway, it's been a somewhat drawn out release despite the 3.7 merge window having otherwise appeared pretty straightforward, and none of the rc's were all that big either. But we're done, and this means that the merge window will close on Christmas eve. Or rather, I'll probably close it a couple of days early. For obvious reasons. It's the main commercial holiday of the year, after all. So aim for winter solstice, and no later. Deal? And even then, I might be deep into the glögg. Linus

Simple convert images using ImageMagick - convert features

Can be done by using ImageMagick.This is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats over 100. Using ImageMagick let you resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.
Install the software under Fedora:

# yum install  ImageMagick 

Convert an image from one format to another. In this case jpeg.

$ convert *.png *.jpg

$ mogrify -format png *.jpg
