^ The above script detects facial features such as face,eyes and smile.There are tons of pre-trained haarcascades available for OpenCV that you can use to detect objects such as Moving cars, traffic signs etc.


drawaframe – A simple way to generate decorative frames for CLI applications

I wrote a small python module to help create decorative intro’s for CLI application.It’s also my first PyPi module 😀


from drawaframe import Draw

Draw.draw_char("*", 20)

Draw.ndraw(14, 6, "", "|")

Draw.draw_char("*", 20)
/usr/bin/python3.6 /home/z/PycharmProjects/draw/playground.py
|                   |
|                   |
|                   | 
|                   |
|                   |
|                   |

Process finished with exit code 0

you can install drawaframe by running pip install command:

sudo -H pip install drawaframe



Whirlpool hashing with OpenSSL in C++

#include <openssl/whrlpool.h>

using namespace std;

int main(int argc, char** argv) {

 cout << "you have entered:" << argv[1] << endl;

 char hash = argv[1][0];

 unsigned char digest[WHIRLPOOL_DIGEST_LENGTH];
 char tohash[] = {hash};

 WHIRLPOOL((unsigned char*)&tohash,strlen(tohash),(unsigned char*)&digest);

 char mdString[300];

 for(int i = 0; i < 64; i++)
 sprintf(&mdString[i*2], "%02x", (unsigned int)digest[i]);

 printf("whirlpool digest: %s\n", mdString);

Yahoo! cricket (proxy) API /w Django + RESTful Framework.

UPDATE 30-1-2018: Function updated to work on new Yahoo! Cricket API.


import requests
import json

def yahoo_cric_api(match_id):
    url = "https://cricket.yahoo.net/sifeeds/cricket/live/json/{}.json".format(match_id)
    response = requests.request("GET", url)
    json_data = json.loads(response.text)
    return json_data


A small django app mirror for yahoo! cricket API.It just calls Yahoo! cricket api when a request is made and return’s json response.

Integrate Lychee with Google Analytics

Lychee is a cool-looking open source album script.the best reason to choose lychee is that 1.it does not compress the images(unlike imgur!). 2.can display technical information such as EXIF data. You can find more information about lychee in their website.


Now, i will show you how to integrate Google Analytics(GA) with your lychee. I assume you have already added your website to google analytics. If not

1.add your domain to google analytics

2.in the root Doc F, open index.html

Put the GA code in between <head> </head> tags as shown above.


3.in root Doc F, open view.php

Put the GA code in-between <head> and </head>


It might take up to 1 hour for GA to integrate with your website and start showing stats.
