Follow the given steps to successfully test your PC-
1. Open the PDF in your favorite viewer
2. Open notepad and copy the text from the PDF to notepad
3. Save the file with a .bat extension from notepad File menu (for example cpu-test.bat)
4. Close all windows and double click the batch file (the one you have just created)

The PDF is here Program for testing raw CPU speed

As the source is given you can modify it to fit your needs. Apart from testing cpu speed you can use it to analyze operating system task scheduling, cpu hardware threading, and core merging features.

Modifying the code: Run another big program from inside the loop to see how drastically the execution time changes. You can judge the effect of cache size this way.

1. Download and install OpenCV for win32 http://sourceforge.net/projects/opencvlibrary/

2. Install Microsoft Visual Studio (I tested with Visual Studio .NET 2005 and 2008) if not already installed.

3. Download and install CMake http://cmake.org/.

4. Download and install Python. [optional]

5. Generate solution file (.sln) for visual studio with CMake. See the following screenshots.

Select the directories.
Generate .sln file.
6. Build the libraries with visual studio by opening the .sln file and then pressing F7.

7. The lib files are now at PATHTOBUILD\lib\debug or PATHTOBUILD\lib\release depending on the configuration you select from visual studio. For every new OpenCV project configure to point to this directory for libs. Also add Project>Properties->linker->Input->Additional Dependies: cv200d.lib cvaux200d.lib cvhaartraining.lib cxcore200d.lib cxts200d.lib highgui200d.lib ml200d.lib opencv_ffmpeg200d.lib

8. Set Project>Properties->C/C++->General->Additional Include Directories: PATHTOOPENCV\include\opencv

9. Add PATHTOBUILD\bin\debug to system PATH from control panel. Control Panel>System->Advanced->Environment Variables->System variables->Path->Edit.

10. Create a new project and test the following code:

You can download the visual studio .net 2005 project folder with debug build from here. Note: The code was taken from the official OpenCV book. Change the path to image in the code to match one of your existings.

If you are a bangladeshi and are interested in the japanese language then join this group. The objective is to create a community of bangladeshies whose common interest is learning the japanese language and who are fond of japanese literature, media, and entertainment.

Although elegant the method consists of repetitive calculations which is pain to carry out. A computer implementation of the algorithm can give us the benefit of having the computer consume the pain. But a computer is not always the thing at hand. So, here is a simple Java ME MIDlet which can be run on any CLDC 1.0, MIDP-2.0 device.

Download the jar from here (source included)

In cases where direct manipulation of HTML is not required there is a much simpler but
smarter way. The code is here. The code snippet responsible for generating the report
is highlighted.

For example we start with 7513:

7513+3157= 10670

10670+7601=18271

18271+17281=35552

35552+25553=61105

61105+50116=111221

111221+122111=233332

Thus we get a palindrome in six reverse and add operations.

Here is a simple python program to do the dirty reverse and add and give us the palindromes.

Notably, not every integer yields a palindrome this way. For example 196 does not.

Palindromes with Python

http://music.music.com.bd/Music/S/Sumon%20&%20Anila/Ekhon%20Ami/02%20-%20Sumon%20&%20Anila%20-%20Ekhon%20Ami%20[music.com.bd].mp3

So the downloaded file (downloaded with Multiget) has the name:

02%20-%20Sumon%20&%20Anila%20-%20Ekhon%20Ami%20[music.com.bd].mp3

But it’s awesome so I renamed it to:

02 – Sumon & Anila – Ekhon Ami [music.com.bd].mp3

Which looks much prettier. But as I continued to download more mp3s it felt
labourus to rename every single file that I download. So I thought about some
automation script. Batch file (Windows) / Shell script (Linux) would be good
enough but that would require me to manipulate the name string directly to replace
the %20s with spaces. Not a big deal but the name could contain things other
than %20s (spaces) . So a better solution, I thought, would be Python’s url decoder.
Here is a snapshot of the code from my favourite editor IDLE and also a download link to the python source file.
Place the python script in the folder containing your files and double click on the
script to see it at work!

Source code – rename (decode) file name

1.  On the taskbar’s right corner (System tray) right click on the Volume Icon.

2. Click on Open Volume Control menu item.

3. A window titled ‘Front Speaker’ appears. From the munubar choose Options>Properties

4. In the ‘Properties’ window choose Adjust Volume for (Group box) Recording (radio button).

5.  Chek ‘Stereo Mixer’ and ‘Mic’ and uncheck everything else and click OK.

6. A window with two sets of widgets seperated by a vertical line appears one titled Stereo Mixer & another titled Mic. Check Select of Stereo Mixer.

To ensure that the setup is working, play your favourite music on your favourite player and open up Sound Recorder (Start>All Programs>Accessories>Entertainment>Sound Recorder) and start recording.
