Cover Lock

Cover Lock, Simple Cover Lock, Proximity Cover Lock, Smart Cover Lock, Automatic Cover Lock, Auto Cover Lock, Flip Cover Lock


Google Play Link :-


This app is developed for users who forget to lock their android screen before putting android phone in cover/pouch.
This app uses sensors of your android phone to detect whether phone screen is covered or not. If screen is covered then this app locks the phone.Whenever user uncovers the phone, this app makes the android phone screen on, to unlock.Sometimes if you want to play some game then this app will lock your screen when your fingers move around the sensors of your phone.This is quite irritating and thats why you have to keep a widget of this app on your homescreen.

Using widget you can on/off the sensors, so even if your fingers move around sensors while playing game, it will not lock the screen. After sometime if you want your screen to lock as soon as it goes into its cover, tap the widget and sensors will be on again. 🙂

For the first time this application will ask for activating the ‘Admin Lock’ of android phone. Activate it to use this application.

Suggestions from the users are invited. More features will be incorporated in the future versions.

Call Forwarding Best Android App

Google Play Link :-


This Call Forwarding app is used to forward calls to your other numbers. You can choose number from your contact list and can forward calls to that number.for now we have implemented only for forwarding unconditionally or unanswered. Future versions will include more of call forwarding options.

You can open this application from application icon or you can put an app widget on home-screen.

This App is very useful to you if you require frequent call forwarding to other numbers. Instead of going to settings then call settings and then call forward settings and then finally configuring your call forward, you can simply configure call forwarding in one click using this app.

You just need to put required number in the textbox and on click of ‘Forward’ button, your call forwarding will be active.

Your contact list will appear on click of contact button. On selecting contact by name, will put the its number in the textbox and hence no trouble to remember contact number.

In a nutshell, this app provides ease to call forwarding.

With new updated version of this app, you can retain the last number used to forward calls. So no need to enter the number every time while forwarding.

With version 2.0, if you have more than one number for a contact you can choose a number. All the numbers of that contact will be showed in a list as soon as that contact is selected. The number selected will be set in textbox for forwarding.

This is FREE APP.

New Version 3.0

Previously this app was supporting only GSM/UMTS networks but now it has included support for VERIZON, sprint and T-Mobile networks also. When you start the app, from ‘options menu’ button of your phone, go to settings (if you do not know what is ‘options menu’ then please see screenshot). In Settings you will see a drop-down which prompts to select the network. According to your selected network, it will perform forwarding of calls.

This dropdown has a 5th option a ‘Custom’. If your network is not from first four options then you can use 5th option ie ‘Custom’. On selecting custom, four text inputs and two buttons will be visible. In four text inputs you have to enter call forward codes. These codes you have to obtain from your service providers. After entering all four codes click on save button to save them. Once saved you can then forward your calls :).

There is also a reset button,, in case you have to reset the codes entered.

Feedback :- Please write to us or with your valuable feedback.  We will be happy to know users feedback and requirement.


2012 in review

The stats helper monkeys prepared a 2012 annual report for this blog.

Here’s an excerpt:

600 people reached the top of Mt. Everest in 2012. This blog got about 3,000 views in 2012. If every person who reached the top of Mt. Everest viewed this blog, it would have taken 5 years to get that many views.

VPN Solutions..

virtual private network (VPN) is a private computer network that interconnects remote (and often geographically separate) networks through primarily public communication infrastructures such as the Internet. VPNs provide security through tunneling protocols and security procedures such as encryption. For example, a VPN could be used to securely connect the branch offices of an organization to a head office network through the public Internet. A VPN can also be used to interconnect two similar networks over a dissimilar middle network; for example, two IPv6 networks over an IPv4 network.


VPN systems can be classified by:

  • the protocols used to tunnel the traffic
  • the tunnel’s termination point, i.e., customer edge or network-provider edge
  • whether they offer site-to-site or remote-access connectivity
  • the levels of security provided
  • the OSI layer they present to the connecting network, such as Layer 2 circuits or Layer 3 network connectivity



There are mainly four protocols of VPN


1) Pure Ipsec

2) Ipsec with L2tp

3) ssl Vpn

4) pptp


Soon i will post howto setup all of above on Your Linux System and howto establish tunnel

using this protocol and howto securely communicate..

Executable file in linux

In GNU/Linux systems the file type is determined by its data context (a file is recognized by its data: a script begin with “#!/bin/sh”, an MP£ file with “ID3”, and MPEG file with 0xBA hex code… and so on). So the file extension become unusefull (because if I rename test.mp3 to test.exe or test.txt its data doesn’t change, and remains always an MP3 file and it is recognized as MP3 file). (see the file command!)

Executables files are recognizable by their data, but they can be executable only if it’s execution permission bit is set (do you know about permission bitmask???). If executable bit is set, and if the file is an executable recognized by the running kernel, the application starts.

An executable run with the permission of the caller: so if you run an application as user, the application have the permission of the user. If the user is “root”, the application can do anything root can do!

Then, certain executable can be run only with root permissions, because it may edit some configuration file or anything else. So the application can do its job only if the application was started by the administrator (root).

If any application need superuser privileges, but should be run by any user, executable file have an extra permission bit: the SUID bit (Set User ID). When this bit is set, the permissions at run time doesn’t depends on the application caller, but the file owner (do you about file owner/group?). So if application has SUID bit set and it’s owned by root, when any user run the SUID executable, run application with root privileges.

That’s because GNU/Linux system are harder to break. To modify system configuration (to introduce viruses, root kits, backdoors…) you should break services that runs with root provileges, otherwise none can modify the system. SUID application are very rare, and often they are secure. However, even if an application runs with root privileges, often it is closed into a limited sub-system (called root jail), wich is a minimal system “running” on top of the system. If application is break, it is limited into the minimal system, so it cannot iteract with the real system running.

how rss feed works

Short for Really Simple Syndication or Rich Site Summary, this handy service is revolutionizing the way we search for content. In addition, us web searchers don’t necessarily have to keep checking back to any particular site to see if it’s been updated – all we need to do is subscribe to the RSS feed, much like you would subscribe to a newspaper, and then read the updates from the site, delivered via RSS feeds, in what’s called a “feed reader.” (We’ll get to feed readers in just a minute!) RSS feeds benefit those who actually own or publish a website as well, since site owners can get their updated content to subscribers fast by submitting feeds to various XML and RSS directories. How do RSS feeds work? RSS feeds really couldn’t be simpler. They’re basically simple text files that, once submitted to feed directories, will allow subscribers to see content within a very short time after it’s updated (sometimes as short as 30 minutes or less; it’s getting faster all the time). This content can be aggregated to be viewed even more easily by using a feed reader. I’ve written up an article on the best feed readers out there. A feed reader, or feed aggregator, is just a really simple way to view all your feeds at one time via one interface. For instance, I have a Bloglines feed. I have all sorts of good stuff in there. Can you imagine how much time it saves me to have all these topics sent to me in one place rather than me searching it out? In addition, all these people who have their sites syndicated on my Bloglines roll are enabling their content to be seen by me and other people who wouldn’t necessarily find them in the search engines or directories. RSS feeds are a wonderful resource, and the uses for RSS are only just beginning to be realized; not only for search engines and searching, but in how we optimize our sites.


open suse is one of finest Linux distro i have used, and am in love with that.
