    Busy since while, and then remembered my first Linux Ubuntu machine .     How i had built my machine , all the configuration files , themes, icons, mouse cursors and etc, My favorite package (In Linux Softwares called packages) pulseaudio-equilizer,  which enable audio bass, audio-effects in linux. it was alternative for windows audio effect like realtek software. it is best.     Then remembering my second distro linux-mint.. and then i started all other linux distros like kali linux, backbox linux, debian, and many more (i even not remember others) numbers are countless which i has tested.     And then the Beast catched my eyes....that was distro called "Arch".....     My mind blown said "WOWW that all the things i want"......     because i wanted make iron man (big dream)  my self i have to make my own Linux os.

I published my first app on Play store P music player. why i publish this ughly UI app on playstore without even no ads and no in-app-purchases.              when i first downloaded poweramp or google music play , i love both poweramp has my favourite feature which is folder view play. i love folder view play, what it does it allows user to play songs only from that single folder .        how it helps user. so we dont have to make playlist we can make folder for some songs which are available also on pc , mobile and USB , so you can listen all you loved songs on any devices , thats the main benefit.       how it is more usefull than playlists........so if you create playlist on android. it works across all your android apps, but what about pc...if you want same songs on them too, so people like non-tech are unable to do that... May be technical guy can do  that but what about othe...

SO Now a days drone is very popular technology in world companies are growing very well startups are growing on drone buisness,             But what happen here in India well honestly pepople are so intelligent in india they find the way of using technology that none of people in any country can .             Well they are so smart but the thing is ., drones have live camera, perfect stablization and 4K cameras , nice interface to do any thing .             "ANYTHING"...........            This technology is awesome honestly when i fly My drone. ( HOME MADE based on arduino )  feels like iron man            but there is a risk drones can fly up to some feet where we can easily examine whats happening around the city             drones can goes up to 30km as well, this technolgy can cha...

hello guys in this tutorial we will take a look at how to detect faces in python using opencv code : - ########################################### #robokishan #don't just copy and paste it will never work  install opencv and also modules required for it #then just download opencv from git and copy this file "haarcascade_frontalface_default.xml" #if you have such a brain this code speaks lot more than i show just figure out what else you can do #uncomment some useful stuffs #!/usr/bin/python import cv2 import numpy as np face_cascade = cv2.CascadeClassifier("haarcascade_frontalface_default.xml") # eye_cascade = cv2.CascadeClassifier("haarcascade_eye.xml") # smile = cv2.CascadeClassifier("haarcascade_smile.xml") cap = cv2.VideoCapture(0) while True: ret , frame  = cap.read() gray = cv2.cvtColor(frame , cv2.COLOR_BGR2GRAY) faces = face_cascade.detectMultiScale(gray , 1.3 , 5) for (x,y,w,h) in faces: cv2.rectangle...
