Screen / Desktop Recording in Gnome 3 { Linux } or above

There is always a great demand of a good screen recorder in Linux from a long time , so Gnome 3 included in as a inbuilt app without much hype . It is pretty simple app . You press the required buttons and it starts recording {as simple as that }.
The  shortcut to launch the Screen Recorder is Control+Shift+Alt+R.
The shortcut remain the same to stop the recording.
The recorded file goes into the home folder and it is named as shell-date-n.webm
The benefit of webm file is - that you can play this file in any modern browser.

See the Gnome 3 Screen Recorder in action below{Right below corner -The red dot}

Ubuntu 12.04, Linux Mint 13, Open Suse 12.2 ...etc

Linux Mint 13 dubbed - Maya {cinnamon} RC review and screenshots

Mint is my favourite distribution since I came across it{It was mint 8 then}.

Then I tried ubuntu 9.04,ubuntu 9.10,ubuntu 10.04 and I  satisfied more than fedora 8 and 9. Then I tried mint 9 and then there is  no coming back. I find Mint 9 very smooth. It has been past two years and I am still sticking with Mint 9 {have 32 and 64 installed side by side}. And I have no issue whatsoever with these 2 versions of mint. Due to several issues going in parallel like Gnome3,Gnome2,Unity I made my mind that I will switch to LTS either Ubuntu or Mint which suits me best. I tried Ubuntu 12.04  last week and find unity not so bad- you just  need some to time to get used to it..{same in the case for Gnome3}. Since then I was waiting for Mint 13 so called { Maya }. Then I see the mint blog about  Mint 13 RC release . Then I downloaded it without waiting anymore{I saw two versions and finally settle to download Mint 13 cinnamon version}. Below is the some keypoints....
Welcome screen ....more finished Icons....

uname -a details

Things to Note:::
1. Linux Kernel-3.2.0.23-Generic
2. vlc ,banshee player
3. Yahoo by default in  search box in Firefox
4. Libre Office 3.5.2.2 
5. Gnome 2 like feel see below screenshots

Final words- Still have to try Mate version{Next review will be Mint 13 Maya Mate version}. This version is mate is although RC but It runs very fine through out review in my VMware and I adjusted its Resolution manually to 1360*768 and it worked fine...

For those who can't live without Gnome2 menu feel --Mint 13 Maya Cinnamon is for you.......

Don't afraid using Torrent - Use Torrent legally

Many of us don't know the real use of so called "Torrent". Torrent is actually a P2P{Peer to Peer} file sharing functionality. It has been wrongly used to download illegal stuffs{you know what I mean}from a long time. But its basic idea was to remove the dependency from a single point{so called server}. A single file can be downloaded from hundreds of people having the same file. The use of torrent have multiple benefits during a file download....

1. Heavily reduces the server traffic{load} to download the large files. simple example- http://fedoraproject.org/en/get-fedora-all
the site contain three options ....a. Torrent {Almost zero dependency on the site } b. direct download {server has to be always live to get the ISO downloaded....worst option from  a server point of view..} c. metalink {almost provides same functionality as torrent ...client remains the same like utorrent}...

2. Faster download speeds...{Usually every server has a download speed cut-off may ...Usually its under 2 MBPS...but with torrent there is no limit, you can download a file  with any speed ...depends how many seeders are there for the file...

3. Good Pause(Resume) support - Every torrent client has support to pause/resume the download at any time. Direct download sometimes fails to do that..

So the bottoms line is - Whenever you go for a large download , search for torrent option if present use definitely ...Usually all open source project provides torrent link on their official site...{This is what the real use of torrent}
Here is my kget and Transmission screenshots..

Using Mobile's Hotspot as Wifi-modem or DHCP server

I may be little late to share this or may be this is not a new stuff for you. But it's better late than never.
If you have a smartphone with hotspot or any wifi-hotspot software in a laptop. Then you can connect several wifi devices to your HotSpot. This  will create a network of devices and you can easily do your networking stuffs between those devices. Let me set a example of my condition :::
I have a laptop running a local server{website} but it doesn't have a DHCP server so its hard for me to run my local website on other's computer because the other computer/Mobile  may have different OS like symbian/Android/iOS/Linux/Windows.  So what I do is turn on my device's hotspot and connect that Laptop to it which contains the local website. And connect other device to hotspot to check my website's performance on other platforms...
from my android device

This hotspot can be used for following purposes::
1. Networking between incompatible devices.
2. Hacking practice
3. Browser testing 
4. Platform Testing

2. you can actually save bandwidth{as it won't show any pics/ads}
3. Its Open Source
4. try evading firewalls

Here are the Links for you
