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.

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: 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:

by Admin

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).

Link: How to remove Zeitgeist in Ubuntu and why

by Admin

Quoting from the article:

On my desktop I use Xubuntu 12.04, and today i noticed that this distribution shipped by default the Zeitgeist daemon, a thing that I’m not using at all, for what i know.

From Wikipedia:

Zeitgeist is a service which logs the users’s activities and events, anywhere from files opened to websites visited and conversations. It makes this information readily available for other applications to use in form of timelines and statistics. It is able to establish relationships between items based on similarity and usage patterns by applying data association algorithms such as “Winepi” and “A Priori”

Zeitgeist is the main engine and logic behind GNOME Activity Journal which is currently seen to become one of the main means of viewing and managing activities in GNOME version 3.0

Personally i don’t use any tool that use the Zeitgeist Framework and I’d prefer to open a terminal and use locate or find to search for files than having something that log all my activity and so slow down my system, so I’ve decided to remove this daemon totally from my system, please note that if you use Gnome 3 or Unity you could have some side effect, or perhaps the system will just become more faster, like the author of the article: Removing Zeitgeist Sped Up Unity .

Just remember that the information collected by Zeitgeist are stored for use in various forms in Unity: showing what were the last application you used, what are the applications you use most, which are the files that were used lately, the music you listen, among many other aspects. If you think you can live without these information probably your system will gain a good sped up.

The remainder of the article at Linuxaria gives provides the actual removal instructions.

by Admin

EDIT: After publishing this article we learned of another article that gives additional information on what is probably the easiest method so far:

Yesterday, developer and programmer extraordinaire Erich Hoover and I spent several hours working out all of the Netflix Desktop kinks. Most users will have no problems with installation now.

Here is how to install the Netflix Desktop App on Ubuntu. …

Full details here:
PPA for Netflix Desktop App (iheartubuntu)

Should you have problems getting it to work, see:
Report Netflix App Bugs on Launchpad (iheartubuntu)

What follows is the original text of this post, which also mentions this method as one of the two choices:

Running Netflix is entirely possible in Ubuntu Linux 12.04 (and most likely any other modern distribution). See the section below “Running with Wine”.

Until recently there was no simple solution to watching streaming movies via Netflix (Watch Instantly) in Linux for any Linux distros besides Android based computers. Netflix has not released a player that will install natively in any of the others.

Link and Video: Drastically Speed up your Linux System with Preload (and other speed-ups)

by Admin

Preload is an “adaptive readahead daemon” that runs in the background of your system, and observes what programs you use most often, caching them in order to speed up application load time. By using Preload, you can put unused RAM to good work, and improve the overall performance of your desktop system.

Most Linux users should install Preload using their distribution’s Software Center or repository, and simply installing the program will be all that is needed.  But this article explains much more about Preload, including various configuration options:

If you ever play video using VLC and it is jerky or drops frames, try this

by Admin

In VLC’s preferences, note the setting for “Use GPU accelerated decoding” — on most systems with modern graphics hardware this should be checked, but is not by default. So, check the box and then click Save. You can always change it back if it makes things worse, or causes videos to not play at all.

VLC Preferences — Input and Codecs settings — use GPU accelerated decoding
VLC Preferences — Input and Codecs settings — use GPU accelerated decoding

This setting does not seem to be available in OS X versions of VLC.
