How to Manage Android Devices on Linux

Posted: 28 Apr 2012 07:08 PM PDT

Android is one of the most popular mobile operating systems around. In just a short span of time, this Linux-based OS has soared to popularity thanks to its amazing features and ease of use. When pitted head-to-head against its archrival, that is none other than Apple's iOS, Android usually gets the upper hand thanks to the freedom that it offers to users.

While iOS requires iTunes and a Windows or Mac operating system, an Android device can be managed from any device, be it Linux, Mac, or Windows. Moreover, managing the device, or transferring songs, videos, and documents, doesn't take much effort at all; all you have to do is simply plug in your smartphone or tablet to the computer and drag and drop. That said, not all are comfortable with that method of 'softwareless' management, especially people who switch over from other devices -- mostly Nokia-based and iOS devices -- feel that they need a dedicated software for managing their phones and tablets.

So, if you're a Linux user, and just purchased an Android device, here are some tips that will help you manage your brand new Droid with ease:


Method 1: Managing Without Additional Software

First plug in your Android device using the cable provided in your box. Then, on your device, turn on mass storage mode, which will then pop up the device on your computer. Simply open it with your file manager (Nautilus, Dolphin, or whichever you use) and create separate folders for the files you want to put. For example, you want to transfer Excel spreadsheets, create a folder called Documents, and in there, create another folder called spreadsheets wherein the file will go. It is important that you keep everything organized into proper folders because over time the file system tends to get overly crowded as different apps create their own folders.

When it comes to transferring music, simply open Rhythmbox or Banshee on your Linux desktop. The device will show up in the left pane wherein you could drag and drop all your songs. Sometimes, however, the files show up in folders other than the main Music folder, in that case, you can safely drop them to the designated folder without losing the playlists you created on your device.


Method 2: Managing Using Additional Software

AirDroid

AirDroid is one of the best Android-managing tools out there. Though not a complete Linux-based software per se, it works perfectly well across all platforms, as it needs nothing but your web browser. With AirDroid you can wirelessly transfer files, manage SMSes, apps, and media right from your desktop. You can also copy and organize your music, and even set a song as your ringtone. The software is incredibly easy to use, even easier than iTunes. To get started, all you have to do is pair your device with the web-based version of AirDroid.



QtADB

QtADB, as the name suggests, is a Qt-based Android manager for Linux, Windows, and Mac OS X. Written in C++, the application can be used for managing files, apps, and more. Furthermore, you can use it for taking screenshots, flashing bootloader, boot recovery, Nandroid backup, and more complex tasks. Though the app is more suited for rooters and advanced users, enthusiasts can use it for managing files and apps. The application requires Qt 4.7 libraries to be installed on your computer (libqtgui4, libqt4-network and libqt4-declarative).

TechSource: Best Disk Partition Managers for Linux

TechSource: Best Disk Partition Managers for Linux


Best Disk Partition Managers for Linux

Posted: 26 Apr 2012 08:38 PM PDT

Back in the olden days when installing Linux was painfully tedious, disk management and partitioning was an area even the tech experts refused to venture into. The reason for this reticence was the fact that partitioning, as opposed to most of the other administrative tasks, was the riskiest of them all. If you make one mistake in typing a command, you'd risk losing all your data, thus leaving you in the lurch.

Thankfully though, as time progressed, Linux became more GUI-friendly, and more and more tools started popping up, thus giving new users a chance to tweak disks to their liking. Also, with the advent of tools like Palimpsest, users started feeling more confident while making major changes to their hard drive, all thanks to the user-friendly GUIs these tools offered. Now, Linux has more than half a dozen of such tools that help users partition and manage their disk, and also, help them with multi-booting, bootloader management, and other tasks.

So, if you're looking to tweak or manage your disks, here's a collection of the best disk management tools out there for Linux:


GNU Parted

GNU Parted is a free tool used to create, destroy, check, and copy partitions. It has a command-line front-end called parted and forms the base for the undermentioned programs like GParted and KDE Partition Manager.



Palimpsest Disk Utility

Palimpsest is a disk utility used for S.M.A.R.T. monitoring, benchmarking, partitioning, and software RAID. It is the default partition manager for Fedora and Ubuntu along with many other distributions. The application comes with a very simple user interface, along with some important data about the hard drive. For example, Palimpsest shows warnings if a partition is misaligned or if the disk is unhealthy, thus prompting users and admins to make important fixes to their system. Apart from formatting, ejecting, and deleting a partition, Palimpsest can also help users benchmark their disks and run various self-tests to analyze disk health. On Ubuntu, Palimpsest can be accessed by opening the launcher and typing in 'disk utility' without the quotes.



KDE Partition Manager

Based on the aforementioned parted tool, KDE Partition Manager is KDE-based tool for creating, deleting, resizing, moving, checking, and copying partitions and file systems. Written in C++ and designed using the Qt GUI toolkit, KDE Partition Manager was first seen when KDE 4.1 was released. Though not much different from GParted underneath, the UI blends in perfectly with the K desktop and differs quite a lot from other partitioning tools. In fact, it looks more like the disk management tool on Windows system, except that there's a space for viewing the application and the live progress log.



GParted

GParted is the GUI version of the aforesaid parted tool. It helps users create, delete, resize, move, check, and copy partitions and filesystems. The application is more useful for creating dual boot systems (for example creating space for a Windows 7 installation), reorganizing disk usage, and mirroring a hard disk.


GParted's user interface is quite simple and easy to use. The top bar shows the disk space of the partition and the bottom part of the page lists all the partitions that are available on that disk. Written in C++, GParted, in my opinion, has the simplest UI on the list, and, even when compared to the mighty Palimpsest, it still comes out as the strongest. Apart from plain partitioning, the free tool can also be used for manipulating a lot of different file systems from Btrfs to FAT16. Though GParted comes with a really simple user interface, it loses out to Palimpsest as the latter comes with a lot more features (like S.M.A.R.T. tools and more) and is also a more powerful tool for benchmarking.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Maintaining Remote Web Sites With sitecopy (Debian Squeeze/Ubuntu 11.10)
========================================================================

sitecopy is a tool for copying locally stored web sites to a remote web server (using FTP or WebDAV). It helps you to keep the remote site synchronized with your local copy by uploading modified local files and deleting remote files that have been deleted on the local computer. This tutorial shows how you can manage your remote web site from your local Debian Squeeze/Ubuntu 11.10 desktop with sitecopy.

http://www.howtoforge.com/build-a-full-featured-mail-server-with-postfix-dovecot-postgresql-on-centos-6




Installing MySQL-Frontend Chive (A phpMyAdmin Alternative)
==========================================================

This guide explains how to install the phpMyAdmin alternative Chive. Chive is a free, open source, web-based database management tool with easy administration, super fast UI and state of the art web technologies. It takes advantage of the capabilities of modern browsers. Features include an SQL editor with syntax highlighting and built-in profiling of SQL queries.

CentOS 6.2 - Installing mod_spdy With Apache 2 - Level Novice
=============================================================

SPDY (Speedy) is an experiment with protocols for the web. Its goal is to reduce the latency of web pages. mod_spdy is an open-source Apache module which supports the use of SPDY protocol to the Apache HTTPD server. This allows for faster page loading and more efficient bandwidth utilization when loading https URLs in SPDY-enabled browsers.

-------------------------------
http://www.howtoforge.com/centos-6.2-installing-mod_spdy-with-apache2-level-novice




Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10
=======================================================================

This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Ubuntu 11.10) with GlusterFS. The client system (Ubuntu 11.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

http://www.howtoforge.com/striping-across-four-storage-nodes-with-glusterfs-3.2.x-on-ubuntu-11.10




How To Set Up WebDAV With MySQL Authentication On Apache2 (Debian Squeeze)
==========================================================================

This guide explains how to set up WebDAV with MySQL authentication (using mod_auth_mysql) on Apache2 on a Debian Squeeze server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the Apache server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

TechSource: Samsung Galaxy S III / S3 Rumors And Expectations

TechSource: Samsung Galaxy S III / S3 Rumors And Expectations


Samsung Galaxy S III / S3 Rumors And Expectations

Posted: 24 Apr 2012 07:58 PM PDT

Despite Android's soaring success, the Droidian rumor scene hasn't really gotten as big as the one on iOS. Mac and Apple fanboys in general are perpetually clamoring to get the slightest of glimpse of what goes on inside their walled garden. Apple, which meticulously guards its every little move, leaves no stone unturned in making sure that no one except its employees knows about its next product. And though some might see this as borderline compulsive behavior, it's actually a great marketing move that helps Apple wow crowds with the magical element of surprise.

However, Apple's not the only one diligently protecting its upcoming secrets, its arch rival Samsung too has been keeping things under the wraps just to surprise the Droid-loving fanboys and fangirls. As the successor of the Samsung Galaxy S II / S2 is due to be launched in front of impatient Android users, many rumors about the yet-to-be-named smartphone have started to emerge. Given the fact that it's most likely that the successor will be called Samsung Galaxy S III / S3, Samsung is yet to confirm any of these rumors.


So, if like us, you too are excited about Samsung's upcoming offering, here's a roundup of all the Samsung Galaxy S3 rumors and expectations:


It will be called Samsung Galaxy S III GT I9300

Following Samsung's usual naming conventions, the next phone will most likely be called Samsung Galaxy S3 GT I9300. Multiple sources have confirmed this, and it's quite improbable that the phone will follow any other nomenclature.

It will run Ice Cream Sandwich: Since a bit of time has passed since the launch of Android 4.0, there's very little doubt that ICS will be the preferred OS for the highly-anticipated smartphone.


The Samsung Galaxy S III GT I9300 will sport a Quad-Core processor

Multiple reports have suggested that the Samsung Galaxy S3 will come with a Quad-core Exynos 4412 processor. Furthermore, rumors have hinted at an ample 2GB worth of RAM, and a 2250mAh battery. The processor is clocked at 1.5 GHz thus making Galaxy S3 one of the fastest devices in the market.


The Samsung Galaxy S3 will have a 12 MP camera

Yes, if most of the rumors are to be believed, S3 will, in fact, come with a spectacular 12 MP camera. Cool huh?


The Samsung Galaxy S III will feature wireless charging

Whoa! This just keeps getting better and better doesn't it? I mean wireless charging, that would permanently end my frantic searches for the elusive charger! If reports of a Korean site are to be believed, wireless charging might be the killer feature that the S3 will wow the crowd with.


Launch Date is May 3rd

Samsung has confirmed that the launch event will take place on May 3rd in London. As for what will happen at the event, Samsung had the following things to say:

"Samsung is looking forward to introducing and demonstrating exciting new mobile products at Mobile World Congress 2012. The successor to the Galaxy S2 smartphone will be unveiled at a separate Samsung-hosted event in the first half of the year, closer to commercial availability of the product."


Leaked Photos of the Samsung Galaxy S3

A Reddit user has leaked a photo of what appears to be the Samsung Galaxy S3. Though we're not sure of its credibility, it does, nonetheless, provide some more information about the upcoming product. Engadget has also shared a leaked photo of an unreleased Samsung smartphone that could also be the Galaxy S III.


What to expect? Will it be a success?

So, what can we expect from the Galaxy S2 successor? Well, there is very little doubt that the Samsung Galaxy S3 will get huge amount of pre-orders and sales, unless, of course, they screw things up real bad. Besides Google/Samsung Galaxy Nexus, the S3 may become the second most popular high-end smartphone that can compete directly with Apple's iPhone 4S. Also, as days go by, rumors about the upcoming iPhone 5 have started popping up thus making the smartphone market hotter than ever. We don't know yet whether the Samsung Galaxy S III will beat the next generation iPhone, but one thing's for sure, it will make every Android fan drool.

TechSource: 5 Simple Ways to Download YouTube Videos on Ubuntu

TechSource: 5 Simple Ways to Download YouTube Videos on Ubuntu


5 Simple Ways to Download YouTube Videos on Ubuntu

Posted: 22 Apr 2012 09:40 PM PDT

From making piano-playing cats popular to giving skilled musicians a platform, YouTube has become one of the most pivotal entertainment hubs of our generation. Not only has it successfully revolutionized entertainment; it has also made knowledge and education more accessible to the bleakest corners of the world. Founded in 2005 by three former PayPal employees, no one had thought that YouTube would go on to become the third most popular site on the Internet.

While most people use YouTube for entertainment, there a growing number of people who are incorporating this video sharing site into their studies. Thanks to revolutionary uploaders like Khan Academy, education has become simpler, more accessible, and easy to understand. That said, not everyone has access to the Internet, and sometimes, it's a great idea to download those videos on a thumb drive and share it with others. However, as easy as it sounds, it's not always possible to download videos off YouTube. Thanks to the dreaded copyright laws and a host of other reasons, downloading videos from YouTube is not allowed.

That said, it's not as if you can't download videos from YouTube. There are interesting sites like KeepVid and others that offer the functionality for free. And yeah, if you're on Ubuntu too, there are a few options that will let you bring the best of the video-sharing site to your hard drive.
