Zenity Commands in Linux

What is Zenity?

zenity is a program that will display GTK+ dialogs, and return (either in the return code, or on standard output) the users input. This allows you to present information, and ask for information from the user, from all manner of shell scripts.

For example, zenity --question will return either 0, 1 or 5, depending on whether the user pressed OK, Cancel or timeout has been reached. zenity --entry will output on standard output what the user typed into the text entry field.

Lets see some major & special zenity commands

1.man zenity : By using this command one can easily find the commands inside the zenity.

2.zenity --error text="ERROR"

What are the differences between StaticJsonBuffer and DynamicJsonBuffer?

StaticJsonBuffer ArduinoJson uses preallocated memory to store the data and this is possible due to StaticJsonBuffer. If one has to use this library then firstly they should create t he StaticJsonBuffer just like: StaticJsonBuffer<200> jsonBuffer; then it creates an memory of 200 byte size which creates allocated memory in the system for storing the data static as the name tells it has fixed in size type of memory.Also we cannot reuse the memory once it gets allocated.it has high speed performance. DynamicJsonBuffer This library supports DynamicJsonBuffer since it has parameters for dynamic memory allocation but it will be more useful if we use this buffer in the machine having memory more than 10KB of RAM. to use this syntax is just similar. DynamicJsonBuffer jsonBuffer; This will create one dynamic memory for the system so that it can allocate it more precisely.its size is variable it stores the data in heap.while storing it take time and its somehow pro...
