Step 1: Verify the jupyter notebook location:
$ ll /home/avkash/.local/bin/jupyter-notebook
-rwxrwxr-x 1 avkash avkash 222 Jun 4 10:00 /home/avkash/.local/bin/jupyter-notebook*
Step 2: Configure your jupyter notebook with password and ip address as needed and make sure where it exist. We will use this file as configuration for jupyter as service.
jupyter config: /home/avkash/.jupyter/jupyter_notebook_config.py
Step 3: Create a file name jupyter.service as below and save it into /usr/lib/systemd/system/ folder.
$ cat /usr/lib/systemd/system/jupyter.service
# Step 1 and Step 2 details are here..
Step 4: Now enabled the service as below:
$ sudo systemctl enable jupyter.service
Step 5: Now enabled the service as below:
$ sudo systemctl daemon-reload
Step 6: Now enabled the service as below:
$ sudo systemctl restart jupyter.service
The service is started now. You can test it as below:
$ systemctl -a | grep jupyter
jupyter.service loaded active running Jupyter Notebook
Thats it, enjoy!!

We found 39 companies belong to what we call the “Unicorn Club” (by our definition, U.S.-based software companies started since 2003 and valued at over $1 billion by public or private market investors). That’s about .07 percent of venture-backed consumer and enterprise software startups.
On average, four unicorns were born per year in the past decade, with Facebook being the breakout “super-unicorn” (worth >$100 billion). In each recent decade, 1-3 super unicorns have been born.
Consumer-oriented unicorns have been more plentiful and created more value in aggregate, even excluding Facebook.
But enterprise-oriented unicorns have become worth more on average, and raised much less private capital, delivering a higher return on private investment.
Companies fall somewhat evenly into four major business models: consumer e-commerce, consumer audience, software-as-a-service, and enterprise software.
It has taken seven-plus years on average before a “liquidity event” for companies, not including the third of our list that is still private. It’s a long journey beyond vesting periods.
Inexperienced, twentysomething founders were an outlier. Companies with well-educated, thirtysomething co-founders who have history together have built the most successes
The “big pivot” after starting with a different initial product is an outlier.
San Francisco (not the Valley) now reigns as the home of unicorns.
There is very little diversity among founders in the Unicorn Club
