Run any GUI software in docker container

How to run GUI Applications like firefox in docker container ?

Since Docker is running default in bash mode we provide docker an image which is called dockerfile by which docker is able to run that image in GUI mode.

Steps to create custom dockerfile is as follows :-

Step 1 : Create a custom dockerfile by using the command

vim dockerfile

Step 2 : Create a docker script that will create a custom image.

FROM ubuntu:latest

RUN apt-get -y update

RUN apt-get -y install firefox

RUN apt-get -y install xauth

CMD firefox

Step 3 : Build a custom file using the following command

docker build sample/ -t firefox

Step 4 : Once it get's build we run the docker image using the following command

docker run -it --name firefox --env="DISPLAY" -net=host firefox

Detailed Analysis on Arduino UNO R3

Arduino UNO R3 Arduino Uno is a microcontroller board based on ATmega328P . It has 14 digital input/output pins 6 Analog pins a 16 MHz quartz crystal oscillator with USB connection ,a power jack , an ICSP(In-Circuit Serial programming) header and a reset button actually it has two reset buttons . Also Arduino uno has RX-0,TX-1 that is receiving and transmitting pins on board. Arduino uno contains AREF pin which means Analogue-Reference IOREF pin this pin is provides a voltage reference at which the microcontrller works 3-ground pins 3-Vcc pins Basically the purpose of creating an Arduino Uno is to Control the sensors and the actuators so that it can work accordingly the data which we provide with the help of software . Nowadays people using Arduino Uno in many fields it has very huge scope in the field of IOT(Internet Of Things). Also in my current project which is 2D-printer we have used Arduino Uno which sense the Data and accordingly move the X-Y pla

7 some Intersesting commands in espeak-ng linux

In This Blog we learn how to perform espeak commands inside the red hat enterprise linux What is espeak-ng? eSpeakNG is a compact, open-source, software speech synthesizer for Linux, Windows, and other platforms. It uses a formant synthesis method, providing many languages in a small size. Much of the programming for eSpeakNG's language support is done using rule files with feedback from native speakers.

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 process slow
