Change Jupyter Notebook Default Directory

There are three way to change the default (i.e., start-up) directory of jupyter notebook.

Solution #1
1. Use command line (aka, cmd), run the following command: this will generate a config file (jupyter_notebook_config.py), in your working location (C:\Users[Your Username].jupyter).
jupyter notebook --generate-config
2. Goto that location (C:\Users[Your Username].jupyter) and edit file jupyter_notebook_config.py as follow.
Find line:

## The directory to use for notebooks and kernels.
#c.NotebookApp.notebook_dir = ''

3. Delete the “#” and type your default directory inside the ”. (Make sure the directory is exist, or it may causes some troubles)
For example:

## The directory to use for notebooks and kernels.
c.NotebookApp.notebook_dir = 'E:\Default Jupyter Dir\'

Solution #2
1. Find the Jupyter Notebook execute file.
2. Right click the file
3. Find “properties” tab and click it; this will lead you to the “Jupyter Notebook Properties”
4. Check the pop-up window, and you should see “Start in” property.
5. Change the directory to your default directory, e.g., ‘E:\Default Jupyter Dir\’
Solution #3

This solution is based on Anaconda, since Jupyter Notebook load the profile from Anaconda.

You may see the following information from properties window if you had gone through Solution #2.

"Target: D:\Anaconda3\python.exe d:\Anaconda3\cwp.py d:\Anaconda3 "d:/Anaconda3/python.exe" "d:/Anaconda3/Scripts/jupyter-notebook-script.py" %USERPROFILE%"

1. Goto the Anaconda installed location.
2. Find the ‘etc’ directory in Anaconda.
3. Open file ‘jupyter_notebook_config.json’
4. Add your default directory to the ‘notebook_dir’.

How to generate UML Diagrams from Java code in Eclipse

From: http://fuzz-box.blogspot.com/2012/09/how-to-generate-uml-diagrams-from-java.html

UML diagrams compliment inline documentation (
javadoc ) and allow to better explore/understand a design. Moreover, you can print and bring them to table to discuss a design.

In this post, we will install and use the ObjectAid plugin for Eclipse to produce jUnit lib class diagrams. Then, we will be able to generate UML diagrams by simply dragging and dropping classes into the editor. We can further manipulate the diagram by selecting which references, operations or attributes to display.

Open Eclipse and go to Help > Install New Software
Click on add to add a new repository
Enter name ObjectAid UML Explorer
Enter Location http://www.objectaid.net/update

Next, select the ObjectAid Class Diagram plugin –
it is free – and click Next. The Sequence Diagram one requires a paid license.

Click
Finish to confirm your choices and start the instalation process.

Click Ok on the security warningSelect Restart Now after the installation completes to restart Eclipse.

To create a new UML diagram we start the ObjectAid wizard with
File >
New >
Other… and start typing in the textbox
Class Diagram to filter the desired wizard. Click
Next, and enter a directory and name for the diagram.

Drop java source or compiled class files into the visual UML editor to start populating the diagram. Right click on a generated class to bring up a context menu and adjust visibility, operations attributes, etc as you like.

Below, we see the
Assert class from the jUnit library with all operations and fileds hidden.

From the context menu, we can add implementations and associations for a selected class. In the following screen, we add the interface
Test implemented by the
TestCase class.

This is how part of the jUnit UML class diagram look after adding some more classes.

To auto layout the diagram right click anywhere within the editor and select
Layout Diagram. From the same menu, you can export the diagram to an image (
gif png jpeg ) by clicking the Save As Image… menu item

Have fun with the plugin, leave a comment if you like 🙂

The solution of GDB code designed problem in Mac OS X

After MacOS X 10.8, the GDB debugging tool installed will prompt error when used:

Unable to find Mach task port for process-id 28885: (os/kern) failure (0x5).

 (please check gdb is codesigned - see taskgated(8))

This is because the Darwin kernel will refuse to allow gdb to debug another process if you don’t have special rights, since debugging a process means having full control over that process, and that isn’t allowed by default since it would be exploitable by malware. (The kernel won’t refuse if you are root, but of course you don’t want to be root to debug.)
The most up to date method to allow gdb to control another process is to sign it with any system-trusted code signing authority. This is an easy process once you have a certificate (see the section below).

This error occurs because OSX implements a pid access policy which requires a digital signature for binaries to access other processes pids. To enable gdb access to other processes, we must first code sign the binary. This signature depends on a particular certificate, which the user must create and register with the system.

To create a code signing certificate, open the Keychain Access application. Choose menu Keychain Access -> Certificate Assistant -> Create a Certificate…
Choose a name for the certificate (e.g., gdb-cert), set Identity Type to Self Signed Root, set Certificate Type to Code Signing and select the Let me override defaults. Click several times on Continue until you get to the Specify a Location For The Certificate screen, then set Keychain to System.
Double click on the certificate, open Trust section, and set Code Signing to Always Trust. Exit Keychain Access application.

Restart the taskgated service, and sign the binary.

sudokillalltaskgated

codesign -fs gdb-cert “$(which gdb)”
source http://andresabino.com/2015/04/14/codesign-gdb-on-mac-os-x-yosemite-10-10-2/
On macOS 10.12 (Sierra) and later, you must also
Use gdb 7.12.1 or later Additionally prevent gdb from using a shell to start the program to be debugged. You can use the following command for this inside gdb:
set startup-with-shell off
You can also put this last command in a file called .gdbinit in your home directory, in which case it will be applied automatically every time you start gdb
echo “set startup-with-shell off” >> ~/.gdbinit

The image operation of MATLAB — every detail operation of colorbar

Recently in the paper matlab generated height field, online search a lot, do a small summary of their own.

First, if you want to add colorbar to the generated image, you can do it in two ways:
1: Insert — Colorbar in the menu bar of the generated Figure image, or click on the shortcut area at the top to add Colorbar, as shown below:

2: Directly from the command line

colorbar;

If you want to specify the location at will:

colorbar('position',[0.95 0.1 0.04 0.8]);

The data in square brackets refer to the x-coordinate, y-coordinate, width, and height of the colorbar bottom-left point. You can try to change the data and see what happens.

Second, sometimes the resulting colorbar is not what we want it to be. How can we arbitrarily adjust the range and position of the colorbar?

Here is a control method for a program statement:

1、set(a, 'CLim', [0 1]);
2、caxis([0,1]);

before colorbar, you can set its upper and lower limits, usually the second method is relatively simple!

To adjust the value range of the colorbar, right-click on it and select Launch ColorMap Editor

So we want our colorbar to be as big, as long, as big, as wide as we want, and that’s pretty easy!
Click ColorBar, right-click — select Show Property Editor

Click on each of the small rectangles in Location to let our Colorbar position change.

We can even click colorbar in the image

Python scapy module installation and dependency module

Scapy module installation

Windows:
PIP install scapy
successfully installed.
mac:

pip install scapy

Unexpectedly prompt permission problem, then

sudo pip install scapy

Or an error permission denied
so query on the Internet, found that the original MAC system caused by the sip mechanism.
reference: reference link

sudo pip install scapy --user -U

Installation successful.
Scapy module is installed with
and used.

>>python
>>import scapy

No problem. I thought the installation was successful, so I started writing code. Reference code links:

http://blog.csdn.net/hitwangpeng/article/details/49278409 found that at the time of import module after error:

from scapy.all import *

If you encounter an error that does not exist in the module, you simply need PIP Install XX to install the corresponding module.
MAC encountered this error:

importError: No module named pcapy

Then install the PCAPY module and encounter the same permission problem. Use:

pip install pcapy --user -U

After the installation, an error occurred:

ImportError: No module named dumbnet

When installing with PIP, the module did not exist, and I was surprised to find a suitable solution after a web search:
download the source code and install using setup.py.
reference link: https://stackoverflow.com/questions/40272077/importerror-no-module-named-dumbnet-when-trying-to-run-a-script-that-leverage

git clone https://github.com/dugsong/libdnet.git
cd libdnet
./configure && make
cd python
python setup.py install

At this point, the MAC installation is complete and the script Demo mentioned at the beginning of the test is successful.
But Windows encountered a strange error:

    self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126]

The error message goes up to trace, sees is in loads wpcap.DLL this module times gives the error, therefore, searches in the computer, discovers as expected my machine does not have wpcap.DLL file, searches on the net, discovers can oneself download installs wpcap.DLL module. Specific methods, refer to the tutorial, I’m in the way a, has not been successful, then after use method 2 is very effective, recommend to you
reference links: http://www.jb51.net/os/windows/378774.html
Once the installation is complete, import IT and run the script. praise
