Browsing Files On Server Or Network Share In Ubuntu

July 19, 2012 Sangkrit Leave a comment

For browsing files on a server you need to connect to that particular server/network share. After connecting to server/network share present on your local machine or in any external device you can easily download-upload and share different files with different users on your local network.

Browsing files over the network:

Open File Manager
Click Network in the side pane
Now File manager will find all machines on your local area network which are having ability to serve files.

If you are connecting to an Internet server or in-case the machine you are looking for is not visible then you can manually connect to a server. Follow these steps:

Open File Manager
click File
Connect to Server
Enter address of the server
select server type
enter other information if required
Click Connect

Details on server types are listed here:
Servers on internet usually use domain name
Computers on your local area network use the machine’s numeric IP address.
If any othe machine is running Ubuntu use machine’s internal IP address. Otherwise, check the help on that computer.

This will show you the files on the server. Now you are free to browse those files and folders easily.

Cloud Based Scripting Language For Light-weight Application Development In Google Apps Platform

July 16, 2012 Sangkrit Leave a comment

Google Apps Script is cloud based scripting language for light-weight application development in Google Apps platform. It is based on JavaScript, gets executed in the Google Cloud and provides easy ways to automate tasks across Google products including third party services.
Google App Script is based on JavaScript like syntax. It uses Google Web Toolkit (GWT) for creating and displaying elements of user interface. GWT is easy to learn, and completely abstracts the complexity of AJAX/HTML from the developer. It is a Cloud based debugger for debugging App Scripts in the browser. It can be used for creating tools to perform simple system administration tasks etc.

Limitations: Currently it doesn’t allow connection to internal (behind-the-firewall) corporate databases, which is key to building business apps. Lacks other connectivity like LDAP connectivity and limits the level to which GAS can be used in the enterprise.

Linus Torvalds Bought Nexus 7 So Why Not You ?

July 15, 2012 Sangkrit Leave a comment

If you are confused between Nexus 7 & New Samsung Galaxy Note Sporting 5.5 Inch Screen or any other smartphone and unable to take decision then you must know:

Linus Torvalds pre-ordered Nexus 7.
Linus Torvalds is checking delivery date of Nexus 7 again and again.

Now you would be saying that you don’t take your decisions by watching what others are doing. What do you think? You are wiser than Linus Torvalds? You think Linus Torvalds comes in ‘others’ category.

It is good if you don’t watch others and make your decisions but truly this is what you really do but you don’t know. You see adds, you watch movies and you buy stuff.

Many of you purchased Sony Xperia after watching Spiderman but are you really satisfied with Sony Xperia? If you say yes then you are very lucky because others who purchased it realized that the most important feature (seeing what they purchased Sony Xperia) actually don’t works. Hence it is much-much better to watch Linus Torvalds and buy Nexus 7 instead of watching Spiderman and buying Sony Xperia.

Everybody experiences some hardware-software conflict in such smartphones because developers are different. If you are willing to experience this conflict everyday then don’t buy Nexus 7.

Firefox 16 Now Supports HTML5 getUserMedia

July 14, 2012 Sangkrit Leave a comment

Firefox 16 now supports HTML5 getUserMedia. It enables access to webcam without any plugins.

There is an entry in about:config, set that to true. In case you need to add a new entry then:

open about:config
Right click any entry.
Select ‘New‘ >> ‘Boolean‘

Add the following entry and set it true:

media.navigator.enabled

Remember to define callback methods right within the getUserMedia() method as shown below:

navigator.getUserMedia(gumOptions,
function successCallback(stream) {
// Replace source of video element with stream from camera
if(navigator.getUserMedia==navigator.mozGetUserMedia) {
video.src = stream;
} else {
video.src = window.URL.createObjectURL(stream) || stream;
}

video.play();
},
function errorCallback(error) {
console.error(‘An error occurred: [CODE ‘ + error.code + ‘]’);
video.play();
});

It won’t works in-case you defined it elsewhere. No need to use CreateObjectURL to pass the stream the video element. Pass the stream directly. video.src=stream

Paul Rouget of Mozilla, created a video tutorial demonstrating HTML5 getUserMedia:

Introducing Mozilla Persona An Identity System For The Web

July 12, 2012 Sangkrit Leave a comment

Mozilla Introduced Mozilla Persona An Identity System For The Web with three newly updated features:

A Better Way To Sign In: Improved way of signing in to your websites. Instead of managing multiple usernames and passwords across your favorite sites and devices, you get more time to do the useful stuff.

You Own Your Data: Many sign-ins carry your profile data and some even share that info with other sites and social networks. Persona lets you get started with only your email address and you get the option to add profile data later on where you think it’s appropriate.

Ease for publishers: Enabling Browser ID, the underlying Persona technology, on your site only takes a few lines of code and helps build good relationships by providing users with a trusted sign-in option.

You may also try it yourself, visit here.

Setting Up Linux Media Server And Sharing Files Between Multiple Linux Machines

July 11, 2012 Sangkrit Leave a comment

You can connect your multiple machines for sharing multimedia files through a centralized web server. In this tutorial you will learn how to set up Firefly Media Server on Ubuntu Server.

What is Firefly Media Server?

Firefly Media Server (formerly mt-daapd) is an free and open-source media server or daemon for the Roku SoundBridge and iTunes. It serves media files using Roku Server Protocol (RSP) and Digital Audio Access Protocol (DAAP).

Features of Firefly Media Server

Support for running on Unix/POSIX platforms
Support for running on Microsoft Windows and Mac OS X
Support for running on the Apple Inc. iPhone and iPod touch
Support for MP3, AAC, Ogg, FLAC, and WMA
Support for Roku SoundBridge via RSP
Support for on-the-fly transcoding of Ogg, FLAC, ALAC, and WMA
On Windows platforms, on-the-fly transcoding of WMA Lossless, WMA Pro and WMA Voice.
Web-based configuration
Support for user-created smart playlists
Integration with iTunes library including reading playlists
Supports serving streaming radio stations

Installing Firefly Media Server

Since we are installing on a Ubuntu Server, the installation is simple:

Open Linux terminal
Run the command sudo apt-get install mt-daap
Enter the user password

Configuration

Open configuration file and look for this line:

mp3_dir = /home/media/music

In this line you need to change to reflect the directory from where you will serve your media.

Here I created a new sub-directory in /opt called music. Perform this action by this command:

sudo mkdir /opt/media

Now make that directory DAAP server readable by using this command:

sudo chmod ug+r -R /opt/media

Other than this there are many more options available in the configuration file like server name, password protection, port, extensions, codec types and many more. Few options are described below:

Servername: Name your DAAP server will broadcast. Default is Firefly RELEASE_NUMBER HOSTNAME.
Password Protection: Limit access of users to the DAAP server.
Port: You may use a port other than the default (3689).
Extensions: The file types to be served by DAAP server.
Valid Codectypes: Configurations for the format conversion.

Starting Daemon

Complete configuration file, go ahead and move your media files into the directory and start the server using this command:

sudo /etc/init.d/mt-daap start

With this running server you can fire up a DAAP enabled client, just like iTunes or Songbird. DAAP server installation is good for small internal network where you can share multimedia files. It requires a running Linux server.

Network Monitoring With Etherape

July 10, 2012 Sangkrit Leave a comment

EtherApe is a graphical utility that allows you to see in real-time where connections are being made on your network, or between your network or computer and the Internet. If you are experiencing unexpected network activity on your computer or LAN and wish to see where the activity is occurring. Both “local” user and “root user” installations are created; in general you must use the root user installation to see all your network traffic.

sudo apt-get install etherape

Features:

Network traffic is displayed graphically. The more “talkative” a node is, the bigger its representation.
Node and link color shows the most used protocol.
User may select what level of the protocol stack to concentrate on.
You may either look at traffic within your network, end to end IP, or even port to port TCP.
Data can be captured “off the wire” from a live network connection, or read from a tcpdump capture file.
Live data can be read from ethernet, FDDI, PPP, SLIP and WLAN interfaces, plus several other incapsulated formats (e.g. Linux cooked, PPI).
The following frame and packet types are currently supported: ETH_II, 802.2, 803.3, IP, IPv6, ARP, X25L3, REVARP, ATALK, AARP, IPX, VINES, TRAIN, LOOP, VLAN, ICMP, IGMP, GGP, IPIP, TCP, EGP, PUP, UDP, IDP, TP, ROUTING, RSVP, GRE, ESP, AH, EON, VINES, EIGRP, OSPF, ENCAP, PIM, IPCOMP, VRRP; and most TCP and UDP services, like TELNET, FTP, HTTP, POP3, NNTP, NETBIOS, IRC, DOMAIN, SNMP, etc.
Data display can be refined using a network filter using pcap syntax.
Display averaging and node persistence times are fully configurable.
Name resolution is done using standard libc functions, thus supporting DNS, hosts file, etc.
Clicking on a node/link opens a detail dialog showing protocol breakdown and other traffic statistics.
Protocol summary dialog shows global traffic statistics by protocol.
Node summary dialog shows traffic statistics by node.
Node statistics export to XML file.

Should I Change My Mind For New Samsung Galaxy Note Sporting 5.5 Inch Screen

July 7, 2012 Sangkrit 1 Comment

I am not sure whether I should change my mind about Samsung’s new Galaxy Note sporting a 5.5-inch screen. It is inconvenient for holding in one hand or against your face but size doesn’t matter if the stuff you carry makes you keep other stuff aside. Likewise hanging a laptop on your shoulder, holding a tablet in your hand, and still keeping a mobile in your pocket is a bad idea.

Nexus 7 is not a subject related to the failure of Google Plus. Google Plus was better than Facebook, it was well-integrated, fast, and really open (unlike Facebook) but it failed because it was not having the critical mass that Facebook already gained. The same thing happened with Facebook’s Email service. This time Facebook was lacking critical mass, unlike Gmail. But quoting this we cannot say that Facebook’s Email service was bad or Google doesn’t know how to work with social networking.

Nexus 7 and Samsung’s new Galaxy Note both work on Android 4.1 Jelly Bean. But I suppose Google knows better working with Android than Samsung. Samsung was only Android’s marketing vehicle before the existence of Nexus 7.

Android is Google’s baby that Google adopted keeping in mind all its services that is why using Android on any machine prompts you to log in with your Google Account so that you can get connected with Google services hence connecting & using your Google account becomes most useful and important activity on any Android machine. I have used other Android machines and a few of them like Sony Ericsson Xperia fail to connect with Google account and you get confused between hardware and software conflicts. So why not use Nexus 7 where everything comes to Google using Google’s machine for Android is a better option as it would be working better than anything else. So I’ll be waiting till October for Nexus 7 release in India.
