SD Times Open-Source Project of the Week: AvroTensorDataset

Earlier this week, LinkedIn announced it was open-sourcing AvroTensorDataset, which is a “TensorFlow dataset for reading, parsing, and processing Avro data.” Apache Avro is the primary storage format that LinkedIn uses for its training data. 

According to LinkedIn, it was experiencing bottlenecks in its machine learning workloads that were caused by the need to read multiple terabytes of input data. AvroTensorDataset can speed up preprocessing of data by multiple orders of magnitude, according to the company.

The tool was built internally at LinkedIn, and it wanted to open-source the project so that others could experience the large performance boosts to training workloads. It has been in production for over a year already at LinkedIn. 

LinkedIn says that with this tool it has been able to improve processing speed by 162x compared to existing solutions and has decreased overall training time by 66%

“ATDSDataset is LinkedIn’s solution to efficiently read Avro data into TensorFlow. Through multiple performance enhancements, we were able to speed up I/O throughput by orders of magnitude over existing Avro reader solutions. Our team at LinkedIn worked closely with the TensorFlow I/O community to open-source this feature, and we hope that by open-sourcing it, the TensorFlow community can also benefit from these performance enhancements,” Jonathan Hung, staff software engineer at LinkedIn, wrote in a blog post.

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
