The Highest-Paying Data Tools
This article was originally adapted from a podcast, which you can check out here.
Two weeks ago for Five-Minute Friday, I covered the highest-paying programming languages for data scientists based on the results of O’Reilly’s 2021 Data/AI Salary Survey. Last week we used Five-Minute Friday to get our definitions of data tools and data frameworks straight so that today we could dig into the highest-paying data tools — while next week, in turn, we’ll tackle the highest-paying data platforms. If you get through today’s episode and don’t feel 100% clear about what a data tool is then consider popping back to Episode #522 to clarify.
The most widely-used tool in the survey — used by nearly a third of respondents — was Microsoft’s Excel program for working with data in spreadsheets. Despite its popularity, Excel — along with other click-and-point tools in the survey — was associated with a below-average salary. Specifically, the mean across all respondents was $146k but those who indicated that they used Excel were paid on average $8k/year less at $138k.

When I teach Deep Learning, the question I get most often is: "Should I be using TensorFlow or PyTorch?" In this recent talk at the DataScienceGO conference, I provide my most thorough and polished response yet.
Thanks to Harpreet Sahota for hosting the session masterfully and leading the audience Q&A at the end.
The Gradient of Quadratic Cost
In this week's video, we derive the Partial Derivatives of Quadratic Cost with respect to the parameters of a simple regression model. This derivation is essential to understanding how machines learn via Gradient Descent.
We publish a new video from my "Calculus for Machine Learning" course to YouTube every Wednesday. Playlist is here.

Open-Source Analytical Computing (pandas, Apache Arrow)
The legend Wes McKinney is this week's guest! He details the genesis of the ubiquitous pandas library, the forthcoming edition of his bestselling book, and how Apache Arrow brings analytics into the distributed computing era.
Wes:
• Created pandas, the industry-standard Python library for data analytics
• Co-created Apache Arrow, a language-agnostic open-source library for efficient analytics on modern distributed CPUs and GPUs
• Wrote the classic O'Reilly Media desk reference "Python for Data Analysis"
• Has worked as technical expert at prestigious firms like Cloudera, RStudio PBC, Two Sigma, and AQR Capital Management
• Today serves as co-founder and CTO of Voltron Data
In this episode, Wes takes us on a technical deep-drive through:
• The creation story of his now-ubiquitous pandas library
• A sneak peek at the third edition of his international-bestselling book
• What the Apache Arrow project is and why it's poised to revolutionize the data science and software industries
• The software and hardware tools that he uses daily to be such an epically productive software developer and entrepreneur
• Responses to great questions by listeners Daniel, David, Doug, and Brett

Linear Regression Fit Point by Point
With this new video, the past months of my "Calculus for Machine Learning" videos all start to come together, enabling us to apply the simplest ML model: a regression line fit to individual data points one by one by one.
This simple regression model will enable us, in next week's video, to derive the simplest-possible partial derivatives for calculating a machine learning gradient.

The Highest-Paying Programming Languages for Data Scientists
This article was originally adapted from a podcast, which you can check out here.
The beloved technical publisher O’Reilly recently released their 2021 Data/AI Salary Survey. It covers responses from 3000 survey respondents in the US combined with another 300 respondents from the UK. All of the respondents are subscribers to O’Reilly’s Data & AI Email Newsletter.
There’s quite a lot of detail in the report on how the salaries of data professionals vary, including by gender, level of education, career stage, industry, and geographic location. Today, I’m focusing on how salaries vary by programming language since this is an attribute that you can easily change about yourself, simply by learning something new.
