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 the 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 process slow

How to run Docker inside Docker Container?

Step 1 : Docker pull centos Step 2 : 1. mkdir storage           2. cd storage/ Step 3 : docker run -it --privileged -v /root/storage:/var/lib/docker --name os1 centos 1.    We used  privileged  mode because to run docker engine inside docker container it will be failed due to some security reason. A  privileged  container means it have all root capabilities of host machine 2.    Docker store all data like containers, images, networks, plugins and many mores inside in one place that is  /var/lib/docker,  so this folder is most important folder. We know if we terminate any container than all the content inside the container will be removed. So, for that reason we create a folder that is  mystorage  inside in host machine and linked this folder with that folder  /var/lib/docker  means we create a persistent storage of that folder  /var/lib/docker Now we install docker on  centos...
