5. To supply command line arguments to the program Right-click the project node, choose Properties, and select the Run node in the dialog's left pane and then enter the arguments at the arguments dialog box

6. To run the project choose Run à Run Main Project (F6) from the Run menu

7. If you build a project and then later change classes, it is good to remove all build artifacts from your system and create a fresh build of the application. You can do this with the Clean and Build command (Shift-F11)

13. Generally speaking, Code Completion is useful for filling in missing code, such as symbols and keywords, automatically. As of NetBeans IDE 6.0 you can now also use Code Completion to generate whole methods. This is useful if you want, for example, to generate a constructor, override methods, or implement methods.

14. Generating Code Using the Code Generation Dialogs: Alt-Insert. Using it we can generate getters, setters, hastcode() and equal() methods

15. The IDE's Java editor provides several ways to add import statements for one or more classes, each offering you a list of possible classes to import when you click on the light bulb error mark or press the appropriate key combinations. In addition, the Editor also displays error hints that assist you with removing imports that aren't needed in your source.

16. Place the cursor on the line of the class that wasn't imported and press Alt+Enter. Alternately, you can click the warning mark in the Annotation Stripe (along Editor's left edge)

17. The IDE's Java editor also provides several other methods for managing imports, such as pressing Ctrl-Shift-I to import multiple types at once and pressing Alt-Shift-I while the cursor is positioned in a type identifier, which enables you to import that specific type

18. To duplicate/move the current line or multiple selected lines: Position the cursor on the line or selection you want to duplicate/move. Press and hold Ctrl-Shift / Alt-Shift, then press either the Up or Down cursor key to copy and paste the code above or below the original line.

19. To instantly Rename all the occurrence of a field, method, variable etc., place the cursor on the filed and press Ctrl+R and then enter the new name. To exit from it press Enter / Esc

20. To see the javadoc for an element press Ctrl+Shift+Space

Artist got automated

Here is my first Tensorflow run to convert images to different styles of famous painters I am using the code that is available at  https://github.com/lengstrom/fast-style-transfer It uses specific versions of below libraries !apt install ffmpeg !pip install tensorflow==0.12.1 !pip install numpy==1.11.2 !pip install scipy==0.18.1 !pip install pillow==3.4.2 I started with latest version and that triggered failure after failure. If you are like me, add below changes to their respective files #This is to make tensorflow behave as if it is in v1 File : evaluate.py and ./src/transform.py import tensorflow.compat.v1 as tf tf.disable_v2_behavior() #Image functions are removed from scipy.misc module. so use imageio instead import imageio scipy.misc.imsave(out_path, img) --> imageio.imwrite(out_path, img) img = scipy.misc.imread(src, mode='RGB') --> img = imageio.imread(src, pilmode='RGB') Refer this post on more details on imageio changes Here is the ...

My algorithmic Trading journey

Like many i used to manually watch and trade stocks, ETFs. Its non-productive and involves our emotions in trading decisions. So I wanted to automate trading. Initially used Trailing Stop and Limit orders. But they can automate only in a prescribed way. I started thinking about a way to trade programatically, where we have more control. My quest pointed to Zipline, a python algorithmic trading library. It support backtesting (testing algorithm with historic data) and most importantly supports live trading In this blog, I will walk you through my algorithmic trading journey. Zipline Installation From  https://www.zipline.io/index.html , I see it only supports python 2.7 or Python 3.5 Since python 2 was sun set on Jan 1 2020, there is no point in trying it. I went ahead with Python 3. For programming, installed latest Ubuntu 19.10 in a virtual machine . Ubuntu 19.10 comes bundled with Python 3.7.5. You can check your python version by typing python3  -V ...
