Browsing Files On Server Or Network Share In Ubuntu

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.

Bypassing Social Reader Apps In Facebook

Leave a comment

Many Facebook stories that appear on your newsfeed require Social Reader App to open access so you can read them. The main problem with the Social Reader App is that it broadcasts your profile activity to newsfeed of other sites hence each of your friend know what you are reading on Internet. If you don’t want your friends to know what you are reading then you should bypass the Social Reader App:

  • In most cases Facebook offers cancel button whenever you click any link that require Social Reader App. Clicking cancel button redirects you to the article without publishing it on other networks.
  • Some Social Reader Apps like Yahoo when posts links on newsfeed doesn’t give cancel button and immediately posts the link on your Timeline. In such condition move to: Privacy Settings >> Ads, Apps and Websites >> Edit >> Apps you use >> Edit Settings >> Select your App >> Click Edit And Now select “Only Mean” on Posts on your behalf . This manages who can see posts this app makes for you on your Facebook Timeline.
  • Now the easiest way to read any article that requires Social Reader without letting anybody know is to copy the heading of that article and paste it on Google search and read it. Actually all those articles that require Social Reader on Facebook are open on the web so you can read them from somewhere else.
  • If you need to block Social Reader App permanently then open App Menu present on your Facebook’s Homepage, look for Social Reader and click [x]  to remove it.

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

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 ?

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

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:

Adding JavaScript Inside Your WordPress Posts

Leave a comment

While writing any post change mode from Visual to HTML and paste your javascript there.

Excluding this there are many plugins available which allows you to add javascript in WordPress posts.

You may try this plugin also Custom fields shortcode. Although this plugin hasn’t been updated in over 2 years but it works good without  showing any error in my blog.

Useage:

Use [cf] shortcode in your post content to show the custom field value without editing any of your WordPress theme files.

For Example:  [cf] FieldName[/cf] returns value of ‘FieldName’ custom-filed.

Introducing Mozilla Persona An Identity System For The Web

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.
