SD Times Open-Source Project of the Week: Data Profiler

Data Profiler is an open-source Python library that originated at Capital One to analyze datasets and detect if any of the information contained within is sensitive data, such as bank account numbers, credit card information, or social security numbers. 

According to the company, when data streams grow large enough, it can be quite difficult to monitor the data coming through, opening up the possibility for sensitive data to make its way past. The goal of the project is to be able to detect when that type of information is present in a dataset. 

The company provided an example of how one might use Data Profiler by imagining a jeweler in the business of buying and selling diamonds. They have a large database with all of their customer and transaction details, in a structured format of rows and columns. Data Profiler can be used on the dataset to get statistics on each column. 

“You’ll learn the exact distribution of the price of diamonds, that cut is a categorical column of several unique values, that the carat is organized in ascending order, and most importantly, you’ll learn the classification of each column for sensitive data. Our machine-learning model will then automatically classify columns as credit card information, email, etc. This will help you discover if sensitive data exists in columns they shouldn’t exist in,” Grant Eden, who was a principal software engineer at Capital One, explained in a blog post. 

Data Profiler comes with a default set of 19 labels that are used to recognize data categories, such as ADDRESS, CREDIT_CARD, EMAIL_ADDRESS, PHONE_NUMBER, SSN, etc. 

“Our library has a list of labels of which a subset is considered non-public personally identifiable pieces of information… the data labeler is able to use that deep learning model to identify where that exists in a dataset… and calls out where that exists to that user that’s doing the analysis,” Jeremy Goodsitt, a lead machine learning engineer at Capital One, told SD Times previously.

The labeler model can also be customized to meet specific use cases. In the example of the jeweler, they could customize the data labeler to help them be able to identify specific gem types. 

At the time of this writing, the project has 1,600 stars on GitHub, has been forked 146 times, and has 48 people contributing to it.

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
