A user may wish to use SSH with Tor for any number of reasons. To do this, download and install connect.c (above) and then add this line to your SSH configuration:

Terminal
localhost:~ $ nano ~/.ssh/config

Compression yes # this compresses the SSH traffic to make it less slow over tor

ProxyCommand connect -5 -R remote -S localhost:9050 %h %p

After this has been added to the SSH configuration, a user can simply ssh myserver to be routed through Tor to the hidden service (or clearnet server). This can also be done with proxychains, but the ProxyCommand directive is a permament solution.

ROS on Android Phone | Finaly done with ROS(Robotic Operating System) on android

ROS on Android Phone

 

Finaly done with ROS(Robotic Operating System) on android 

It was my 1 day work for getting an output from android to ROS Server .I will explain the procedure that i have done
Prerequisites:
1)android-sdk for linux -Refer the following site for manually download android component .Othervice you have to setup eclipse for doing it
2)platform-tools-This is the most required thing in this installation operation

Procedure:
1)Download android stack from ROS website
2)There is a README file in this stack describing the installation procedure .But there will some error when you follow it
Note :The error i got the installation operation is with adb
Starting of adb is like follows
#./adb kill-server
#./adb start-server
#./adb devices
It will print if the device is connected
#./adb shell
Set the Link path of python from README file
Change the link path according to your android path .Othervice it will show error
It is better to install Pythonforandroid and sl4a manually .
Set the adb path in .bashrc file on home folder
eg :export ADB=~/android-sdk/platform-tools/adb
After installation using make install command
You have to enter
$make cv_module
$make ros_sample 

After that you have to take pythonforandroid and press importmodule option
It will show cv.egg ,select and install it
Connect android phone and computer though a wifi network ,preferably through a router .
Take ros.py from sl4a script folder .Run it
It will ask for ROS_MASTER_URI ,for URI you have to note the IP of computer which running roscore .For eg:My system IP was 192.168.1.2 So theURI is

eg : ROS_MASTER_URI=http://192.168.1.2:11311
URI=http://IP:11311
Note:i have some issues in importing cv .So i commented the cvsection and working only on accelerometer ,vibrate ,speak functions
Here is the edited ros.py

# start sensor polling in background
droid.startSensing()
while not rospy.is_shutdown():
# read the accelerometer and store result
acc = droid.sensorsReadAccelerometer().result
# if new sensor values have arrived, output them
if isinstance(acc[0], float):
# acc_str = “%s – Acc: %f %f %f” % (rospy.get_time(), acc[0], acc[1], acc[2])
acc_str = “X:%f Y:%f Z:%f” % (acc[0], acc[1], acc[2])
else:
# acc_str = “Time: %s – No acc. values” % rospy.get_time()
acc_str = “No values.”
rospy.loginfo(acc_str)
pub.publish(String(acc_str))
rospy.sleep(1.0)
# start-up main
main()
Here is the output

Westinghouse Shows Green TVs at CES

Standard

WDE_LD-55F970Z_LED_HDTV.jpg

Energy efficiency is a major theme at CES, and Westinghouse is leading the way with a new line of 8 LED HDTVs that range in size from 24 to 55 inches. Only about 1 inch thick, these sets have a high-gloss black frame complemented by red accents for a graceful, modern look. For an extra visual touch, the acrylic neck of each model’s included stand is illuminated with an understated red glow light.

As for the green, all eight models meet or exceed Energy Star 4.0 ratings, which go in effect in the second quarter of 2010. Moreover, six out of eight exceed Energy Star 5.0 ratings, which go into effect in 2012. The line is spearheaded by the 55-inch LD-55F970Z (above), which offers 1080p resolution, a 6-ms response time, a 120-Hz refresh rate, and judder removal for flicker-free performance.

“We are very excited to introduce our new LED HDTV line,” says Rey Roque, Vice President of Marketing at WDE. “Westinghouse Digital is committed to do our part to help the environment by producing a full line of energy-saving, eco-friendly HDTVs at a great price for the consumer. Our new LED HDTVs provide the same slim, energy efficient and sexy styling of more expensive LED sets at a price that the average consumer can afford.”
