JDeveloper Flickering Issue

Ok, I have to admit that I am trying to shift my JAVA development to JDeveloper, though natively I am an Eclipse user.

I found some issues in the JDeveloper, thought better to report them to you since I am unaware of any fix/issue/bug tracking system.

In JDeveloper if you have the Application Navigator opened, and you just expand and collapse the > Projects, it flickers alot.

I switched to Classic theme.
This is propotional to the items within the project. The more the number of items, the more the flickering is. 

I am using Ubuntu 10.04 LTS, Running on Lenovo X200.

Anti-aliasing


Not able to deleted in a newly created java file in a newly create java project

Imote2 with Camera setup IMB400 over Ubuntu 9.10/10.04

Imote2 Camera driver for TinyOS is available in contribution directory of  TinyOS 2.x . It goes by the name of  tinyos-2.x-contrib . Its location within is  tinyos-2.x-contrib/intelmote2/apps I am assuming that you have tinyos-2.1.1 installed, this is required to have Camera Driver build. If you dont have it installed... than better have it done by invoking: apt-get install tinyos-2.1.1 From here on to get the driver working,  the procedure is as follows: Browse to opt directory. cd /opt The recommended way to get the source of tinyos-2.x and tinyos-2.x-contribis is through CVS. echo "Getting TinyOS 2.x and TinyOS 2.x-contrib from CVS" echo "Press enter when asked for password." cvs -d:pserver:anonymous@tinyos.cvs.sourceforge.net:/cvsroot/tinyos login cvs -z3 -d:pserver:anonymous@tinyos.cvs.sourceforge.net:/cvsroot/tinyos co -P tinyos-2.x cvs -z3 -d:pserver:anonymous@tinyos.cvs.sourceforge.net:/cvsroot/tinyos co -P tinyos-2.x-contrib --OR--  e...

Artificial Intelligence - Weak AI vs Strong AI

Source:  http://www.faculty.umb.edu/gary_zabel/Courses/Bodies,%20Souls,%20and%20Robots/Texts/Artificial%20Intelligence%20.htm Artificial Intelligence As a theory in the philosophy of mind, artificial intelligence (or AI) is the view that human cognitive mental states can be duplicated in computing machinery. Accordingly, an intelligent system is nothing but an information processing system. Discussions of AI commonly draw a distinction between weak and strong AI. Weak AI holds that suitably programmed machines can simulate human cognition. Strong AI, by contrast, maintains that suitably programmed machines are capable of cognitive mental states. The weak claim is unproblematic, since a machine which merely simulates human cognition need not have conscious mental states. It is the strong claim, though, that has generated the most discussion, since this does entail that a computer can have cognitive mental states. In addition to the weak/strong distinction, it is also ...

Tensorflow - Simplest Gradient Descent using GradientDescentOptimizer

Below is the code to find the minimum possible value of weight (w) such that the outcome of equation is closest to 0, using Gradient Descent method. These weights are multiplied with input (x) to compute cost, thus minimizing it. The equation is below... w 2 - 10 w + 25 ---------------------- (i) i.e. ( w - 5 ) 2 Thus, the coefficients from (i) would be 1, -10 and 25 import numpy as np import tensorflow as tf coefficients = np.array([[ 1 ], [ - 10 ], [ 25 ]]) # try 1, -20, 100 -- line 4 w = tf.Variable([ 0 ], dtype = tf.float32) x = tf.placeholder(tf.float32, [ 3 , 1 ]) cost = (x[ 0 ][ 0 ] * w ** 2 ) + (x[ 1 ][ 0 ] * w) + x[ 2 ][ 0 ] # (w-5)^2 train = tf.train.GradientDescentOptimizer( 0.01 ).minimize(cost) init = tf.global_variables_initializer() with tf.Session() as session: session.run(init) print (session.run(w)) for i in range ( 1000 ): session.run(train, feed_dict = {x:coefficients}) print (session.run(w)) T...
