Change Default Editor in Debian

My favourite editor is vim in Linux. I am very comfortable with it. But when I need to do some come some configuration(e.g. crontab -e), operating system opens it with default editor which is generally nano. This is annoying to me. Therefore, I generally change default editor with the following very simple step to vim:

# sudo update-alternatives --config editor
Following table has printed.

There are 3 choices for the alternative editor (providing /usr/bin/editor).

  Selection    Path                Priority   Status
------------------------------------------------------------
* 0            /bin/nano            40        auto mode
  1            /bin/nano            40        manual mode
  2            /usr/bin/vim.basic   30        manual mode
  3            /usr/bin/vim.tiny    10        manual mode


Press enter to keep the current choice[*], or type selection number:
Write <2> and hit the enter.

Result print: 

update-alternatives: using /usr/bin/vim.tiny to provide /usr/bin/editor (editor) in manual mode.
Now, default editor in the system is vim. To see the effect, run command crontab -e. It will be opened by vim.

Convert raw image to qcow2 format: qemu-img convert -O qcow2 image1.raw image1.qcow2 You need the image in qcow2 format for compatibility with openstack platform.  Open the converted image in virt-manager. Before opening, edit disk options. Under ' advanced options ' section, select ' qcow2 ' as ' storage forma t '. Start the virtual machine. You should see the login screen soon. (If you don't set storage format, vm will not find a bootable device. )   If everything is ok so far, close the vm. Take qcow2 image and upload it into glance. It may take time depending on size of it. After this process is completed, open a

Integration of MuPDF Project as a Library into an Android Studio Project

I have needed to use MuPDF library in my android project. After some research, I have seen that there are many integration tutorials but, but integrated projects are developed on Eclipse. For projects on AndroidStudio+Gradle, there is no example. I mean there is no specific example which exactly refers to this issue. So, after achieving my goal, I want to share the steps publicly so that it can be reused by others.

Xposed - How to hook a method with primitive-type parameter

Xposed Framework is a great tool to take actions which Android SDK doesn't provide for developers. One of the great hacks that you can do is hooking a method. You can see parameters given to a method, with many other properties of it. There are some tutorials on Internet, but in this tutorials, they show hooking method without parameters or with class parameters. Its code is: findAndHookMethod("com.android.settings.Settings", lpparam.classLoader, "updateHeaderList", List.class, new XC_MethodHook() { @Override protected void beforeHookedMethod(MethodHookParam param) throws Throwable { //your code } });
