Disrupt Yourself by Whitney Johnson

From the Magazine (July–August 2012) Buy Copies

Summary.   Disruptive innovation has been a pioneering concept in business since 1995. Johnson, a founding partner at Clay Christensen’s investment firm, explains how you can apply disruptive thinking

My career path has been an unusual one. I started as a secretary on Wall Street, worked my way up in my firm’s investment banking group, and then stepped back to become an equity research analyst. Eight years later, I quit that job to produce a TV show and write a children’s book, but I ended up blogging about work/life issues and cofounding a hedge fund backed by a man I’d met at church. It’s not what you’d call a traditional corporate trajectory. But perhaps that’s the new normal.

Based on this documentation.

This topic provides instructions for installing the Snowflake Connector for Python. The connector can currently be installed in Linux, macOS, and Windows environments.

Install the connector:

$ pip3 install --upgrade snowflake-connector-python

Create a file (e.g. validate.py) containing the following Python sample code, which connects to Snowflake and displays the Snowflake version:

#!/usr/bin/env python
import snowflake.connector

# Gets the version
ctx = snowflake.connector.connect(
    user='<your_user_name>',
    password='<your_password>',
    account='<your_account_name>'
    )
cs = ctx.cursor()
try:
    cs.execute("SELECT current_version()")
    one_row = cs.fetchone()
    print(one_row[0])
finally:
    cs.close()
ctx.close()

Make sure to replace <your_user_name>, <your_password>, and <your_account_name> with the appropriate values for your Snowflake account.

Deploying Airflow with Docker and Running your First DAG

Based on content from: Getting Started with Airflow Using Docker, Mark Nagelberg

This rest of this post focuses on deploying Airflow with docker and it assumes you are somewhat familiar with Docker or you have read my previous article on getting started with Docker.

As a first step, you obviously need to have Docker installed and have a Docker Hub account. Once you do that, go to Docker Hub and search “Airflow” in the list of repositories, which produces a bunch of results. We’ll be using the second one: puckel/docker-airflow which has over 10 million pulls and almost 100 stars. You can find the documentation for this repo here. You can find the github repo associated with this container here.

Dynamic Data Masking is a column-level security feature that uses masking policies to selectively mask data at query time that was previously loaded in plain-text into Snowflake.

Using Dynamic Data Masking

Based on post from Venkatesh Sekar, but with lots of code cleanup.

You may be asked to participate in a security and audit review and have to answer some questions like these:

• How are our users connected to Snowflake?
• What are the custom roles that we implemented?
• Which users are assigned to which hierarchy?
• What are the privileges assigned to a particular role, and which privileges are granted via inheritance?
• Given a database object such as a table, how is that table accessed by a specific user and through which roles?
• Are there any ghost or zombie roles?
• Are the roles getting inherited by SYSADMIN or SECURITYADMIN?
• Which users are assigned to ACCOUNTADMIN?
• Are there any tables getting created and assigned to SYSADMIN and not following best practices?
• Can you provide a visual representation of users, roles, and grants in Snowflake?

And so on and so forth.

Use ssh to connect terminal session to PI

You can ssh to connect to your raspberry pi, all you need to know is the IP address,

The default user is pi, and the password is raspberry.

Remote Desktop connection to PI

You can use VNC to remote connect to your PI, using your computer Keyboard and screen to see and control a virtual desktop.

Sodium is a naturally occurring mineral and is found in almost everything you consume—from apples and almonds to water and milk. And while sodium is used to soften water, one of the biggest misconceptions is that it makes your water noticeably salty. Luckily, that’s not the case.

Your daily dose

According to the Dietary Guidelines for Americans, the recommended limit for sodium is less than 2,300 mg a day. The average American consumes about 3,400 mg a day, but the vast majority of sodium comes from table salt and processed and prepared foods, like cold cuts, canned soups, fast food, and frozen dinners. Here are the sodium levels of some common food items:

• An 8-ounce glass of low-fat milk contains about 120 mg of sodium
• One egg contains 59 mg of sodium
• An 8-ounce glass of orange juice contains about 25 mg
• A can of soda contains 40-45 mg
• Depending on the brand, a standard 1-ounce slice of bread has between 80 and 230 mg of sodium
• A teaspoon of regular table salt contains 2,300 mg of sodium

Sodium in Softened Water

“One of the signs of someone who was wise is that they disseminate responsibility,” the late actor Chadwick Bosman told Trevor Noah on The Daily Show. “They use everybody’s skills, they don’t try to do everything. You can’t be everywhere at one time.”

He was speaking about his role in Black Panther, playing T’Challa, king of the fictional African nation of Wakanda — but he could easily have been giving a lecture on modern-day leadership.

As the world become increasingly complex and volatile, the leaders with the most influence understand something important. 

It’s not about having power and control. 

It’s not about efficiency and using employees as a means to drive performance. 

It's not about the leader as the hero(ine) at the center of it all.

To build the teams that can solve big, thorny problems, leaders will have to empower their people to learn, grow and innovate.

This approach is often called "servant leadership" because the leader sees themself as serving, rather than commanding, the people around them.

But there’s nothing servile or weak about it.
