from pymongo import MongoClient
client = MongoClient()
db = client.database
collection = db.tables

You need to import pymongo to connect python with mongo database. Later, connect to running instance of mongo ( default at 27017) . You can use dcker to run mongo instance *single,multiple or cluster)

import psycopg2
from psycopg2.extras import RealDictCursor
from datetime import date
connection = psycopg2.connect(user = "root",
                              password = "password",
                              host = "localhost",
                              port = "5432",
                              database = "database")
cursor = connection.cursor(cursor_factory=RealDictCursor)
cursor.execute("""select * from table where date(created_at)=%s order by id desc limit 100""",(date.today(),))
res=cursor.fetchall()

Explanation :

First you need to import required module.For postgres database access,psycopg2 is latest and recommended modue. RealDictCursor is required to get data in proper dictinary form otherwise data will arrive without column name( hard to guess for wide tables).

Create a connection object with defined connection string. Prepare query. Execute it with a cursor and fetch result from cursor . Fetching and selections will be discussed in later series.

You can start with it. Use the data to apply different types of visualization or draw useful conclusions using python,postgres,pandas and python visualization library

To find count of inotify watcher - cat /proc/sys/fs/inotify/max_user_watches

Set a new limit of inotify watchers - echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf

Apply systemwide changes - sudo sysctl -p

Recheck and confirm changes - cat /proc/sys/fs/inotify/max_user_watches

I will not get into much depth because I learnt python by setting some goals and continously achieved it. Some good source of my learning process –

1. Youtube
2. Udemy
3. Stackoverflow
4. Python documentations
5. My curioscity

Docker help us to reuse softwares without worrying about its environments and sideaffects. You can not easily run 2 versions of software( 2 different version of redis or mongo or mysql or apache etc ) on same host without making any special arrangment. Docker make it portable and reusable. So, do not install , dock it

Some Common cli flags for dockers

1. -d = demonised mode
2. -it = interactive mode
3. -v = attach volume
4. -p = port mapping from host to docker
5. –name = naming an instance for quick reference

Now some popular dockers for us.

1. Couch db server = docker run -d –name couchdb -p 8091-8094:8091-8094 -p 11210:11210 couchbase
2. Mongo db = docker run –name some-mongo -d mongo
3. Postgres = docker run –name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d postgres
4. redis db = docker run –name some-redis -d redis
5. maria-db = docker run –name some-mariadb -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mariadb

I will keep adding more information about docker, container management in coming post.. Switch to better

If you are facing the same problem as stated above, there may be some issue related to path of docker-machine location and virtualbox location.

When docker installed, its path is like /usr/snap/docker and virtualbox is /usr/bin .

Dockermachine is unable to resolve using absolute path. It is searching in relative path( possibly a bug)

I reinstalled docker.io using ( apt install docker.io ) and did custom setup for docker machine for ubuntu 18. Finally I have all executable in nearly same path

I think, this will help you to resolve problem by some extent.

Most of time, you get email attatchments as password protected and whenever you open it, password is prompted and you need to find password scheme ( like dob, contact no + dob , social numbers etc)

Trick 1 :

Open the file in chrome. Put password obtained from mail body or sms etc. Now pdf file opened, just print it ( ctrl + f ) and save as pdf. This new pdf file is password free
