Link: How to Emulate Google Chromecast on Windows, Mac and Linux Desktop

by Admin

Google’s latest hardware offering, Chromecast was an instant hit as it promised a better way of beaming/ controlling  multimedia content from your mobile phone on to a TV than the current choices we have right now. Now when a popular company like Google is trying to solve an age old problem that haunted Android, with a less expensive ($35) hardware, we should expect it to run out of stock. That is what exactly happened to Chromecast as it ran out of stock on all popular online stores including Google’s own Play store. Now if you have already pre-ordered a Chromecast or is in queue, here is something for you impatient folks, ready to play with few command lines.

Github user (dz0ny) has developed a Python package called Leapcast that can emulate the Chromecast hardware in Chromium environment running on your Mac, Windows and Linux. In order to achieve this hack on your computer all you have to do is carefully follow the steps below.

Use Any IR Remote In The House

This tutorial will show you how to use ANY IR remote in your house to control XBMC.
I have used this method with COMPLETE success on many remotes. I have yet to find one that wont work.

To demonstrate this technique I will download and install the latest XBMCbuntu Live CD (Frodo 12.2) to verify it works “out of the box”
If you deviate from the Live CD XBMCbuntu install you are on your own installing and configuring LIRC.

Links: How To Set Up A Wireless Hotspot (Access Point Mode) That Supports Android In Ubuntu

by Admin
A wireless hotspot enables a computer to serve as a router over Wi-Fi. Ubuntu lets you easily create a wireless hotspot by using the Network Manager, but it uses an ad hoc network and most Android and Windows Phone devices can’t connect to such networks.
For this reason, I’ve created (in collaboration with Satya) a script called AP-Hotspot that automatically creates an infrastructure (Access Point mode) wireless hotspot in Ubuntu that should work with Android and Windows Phone devices. The script uses hostapd and dnsmasq and it requires Access Point mode support for your wireless card – AP-Hotspot checks for this automatically and won’t run if your wireless card doesn’t support it.

If you don’t feel comfortable running a script, the script is based on these instructions, so if you want you can do it manually:

Link: Chromecast: Exploiting the Newest Device By Google

by Admin

Chromecast-stockOn Wednesday, July 24th Google launched the Chromecast. As soon as the source code hit we began our audit. Within a short period of time we had multiple items to look at for when our devices arrived. Then we received our Chromecasts the following day and were able to confirm that one of the bugs existed in the build Chromecast shipped with. From that point on we began building what you are now seeing as our public release package.

Exploit Package:
Our Chromecast exploit package will modify the system to spawn a root shell on port 23. This will allow researchers to better investigate the environment as well as give developers a chance to build and test software on their Chromecasts. For the normal user this release will probably be of no use, for the rest of the community this is just the first step in opening up what has just been a mysterious stick up to this point. We hope that following this release the community will have the tools they need to improve on the shortfalls of this device and make better use of the hardware.

Chromecast: Exploiting the Newest Device By Google. (GTVHacker)

Additional comment: These devices might be a lot more useful to some of us if someone could figure out how to 1) Add a wired network connection, 2) Add an optical audio output for those of us with older receivers (that don’t have HDMI connections) and TVs (that don’t pass audio from a HDMI port back to the receiver). They’re obviously selling these to the low-income crowd, so why would they not assume that you might want to connect this to perfectly good but slightly dated equipment that requires optical audio, or maybe even to a large screen computer monitor that doesn’t have any audio capabilities?

Additional additional comment: If the XBMC developers could create an add-on that would emulate the Chromecast device and in effect turn XBMC into a Chromecast receiver WITHOUT the need for the Chromecast dongle, that would make us VERY happy!

 

Link: How to Move Your Home Folder to Another Partition [Linux/Ubuntu]

by Admin

If you have accepted the default option while installing Ubuntu, or that your computer comes with Ubuntu pre-installed, chances are that your Home folder and the system folders all lie in the same partition. This is perfectly fine, but if you want to upgrade your existing Ubuntu version, or reinstall Ubuntu, you won’t be able to preserve your app settings, or even retain your files and documents. One of the good practice is to give the Home folder its own partition, so whatever changes you made to the System folder won’t affect your Home directory, and you can easily upgrade or reinstall Ubuntu with ease.

If you want to move your Home folder to another partition, here is how you can do so.

Link: How to convert from .deb to .rpm and viceversa

by Admin

deb is the extension of the Debian software package format and the most often used name for such binary packages. Debian packages are standard Unix ar archives that include two gzipped, bzipped or lzmaed tar archives: one that holds the control information and another that contains the data. The accepted program for handling these packages is dpkg, commonly used via other programs such as apt/aptitude or Gdebi.

RPM Package Manager (RPM) is a package management system. The name RPM variously refers to the .rpm file format, files in this format, software packaged in such files, and the package manager itself. RPM was intended primarily for GNU/Linux distributions; the file format is the baseline package format of the Linux Standard Base.

If you can only find some software you want to install in one of these package types but you need the other, this article tells you what to do. Note we are just passing along the link, and do not guarantee that this will work:

Link: How to build a cross compiler for your Raspberry Pi

by Admin

A cross compiler is a compiler that runs on one platform/architecture but generates binaries for another platform/architecture. With devices like the Raspberry Pi, where you really don’t have much CPU or memory to work with, if you’re doing any heavy compiling (like when working on the kernel) a cross compiler is the only way to go. For example, I build all my Raspberry Pi kernels on my nice Sandy Bridge Xeon E3 home server where they compile in only a fraction of the time they would on the Pi.

We think Unity pretty much sucks. If you do too, you have choices, as outlined here:

Another choice would be to switch to a better Linux distribution. Many people seem to like Linux Mint; others simply go back to plain old Debian (both Ubuntu and Mint are based on Debian).
