Techfest 2014

Pranav Mistry @IIT Bombay Techfest talking about his sixth sense technology. The enhancement of this sixth sense technology now is useful for any deaf person to interact with anyone. A deaf person will do sign languages. Those sign languages are recorded by this sixth sense technology http://www.slideshare.net/atinav242/the-sixth-sense-technology-complete-ppt . The gestures are processed into words which are then transmitted to a speaker which has words to speech software. The speaker will then speak out the words which the person actually means. Finally talking about open sourcing his technologies.

The system network service is not compatible with this version ...Error solution(Ubuntu)

Check out by the command ifconfig whether what output you get.
If you are facing the problem there are chances you might not get the ip address in the output. For the naive people, in simpler words the output will be just one para and not 2 as it should be.
Try this link

For me this link didn't work but for many the above link worked so try that out first.

My experiment:
1. sudo  vi /etc/network/interfaces
you will see the lines:
auto eth0
iface eth0 inet dhcp

instead type:
auto eth0
iface eth0 inet static


Now do:
2. sudo nano /etc/resolv.conf
Paste below lines:

now restart your network with:
3.sudo /etc/init.d/networking restart

now check

5.ping joindiaspora.com
If this gives response, your net is working ....Hurray!

6.sudo service network-manager restart

This is basically called static ip.

Let me know whether it works or else what error u get take a screenshot and mail me.

wget command

wget utility retrieves files from World Wide Web (WWW) using widely used protocols like HTTP, HTTPS and FTP. Wget utility is freely available package and license is under GNU GPL License. This utility can be installed in any Unix-like Operating system including Windows and MAC OS. It’s a non-interactive command line tool. Main feature of Wget is it’s robustness. It’s designed in such way so that it works in lethargic or unstable network connections. Wget automatically starts downloading where it was left off in case of network problem. Also downloads file recursively. It’ll keep trying until file has been retrieved completely.

Install wget in linux machine
sudo apt-get install wget 

Create a folder where you want to download files .
sudo mkdir myimages
cd myimages

If there are 20 images to download from web all at once, range starts from 0 to 19.
Right click on the first image and choose "Copy Image Location"
Type in terminal
wget http://example/img{0..19}.jpg ---that image location

If you want to convert all the downloaded images into one pdf then

Change Bluetooth name

Requirements : Linux : Ubuntu

I have Ubuntu OS in my system(laptop). There are situations when I want to transfer files from my tab3 to my system through bluetooth in IIT. As all the systems in IIT are configured with Ubuntu OS, all system names are 'ubuntu-0'. It is quite confusing as to which system my tablet is getting connected.

So I changed my system's name. The procedure to do so is as follows:
1. Open your terminal
2. Type
cd /var/lib/bluetooth/XX:XX:XX:XX:XX:XX/

3. sudo gedit config

4. change name 'ubuntu-0' to anything you wish.
5. close the file
6. Reboot the system
