SD Times Open-Source Project of the Week: TorchRec

Earlier this week, at an event on AI in the Metaverse, Meta (previously Facebook) announced that it was open-sourcing TorchRec. TorchRec is a PyTorch library for recommendation systems. 

According to PyTorch, the TorchRec library includes modeling primitives, optimized recommendation system kernels, a sharder for partitioning tables, a planner than can generate sharding plans, GPU inference support, common modules for recommendation systems, and pipelining for overlapping dataloading device transfer, inter-device communication, and computation. 

“Recommendation Systems (RecSys) comprise a large footprint of production-deployed AI today, but you might not know it from looking at Github. Unlike areas like Vision and NLP, much of the ongoing innovation and development in RecSys is behind closed company doors,” Donny Greenberg, product manager for PyTorch; Colin Taylor, senior software engineer for Facebook AI; and Dmytro Ivchenko, software engineer at Facebook, wrote in a blog post. 

According to the researchers, in mid-2020 PyTorch had received a lot of feedback on there not being a large-scale engine in PyTorch. As they searched for an answer, Facebook engineers approached, offering up their production recommendation system and wanting to build a community around it. 

From Facebook’s initial contribution, the community began modularizing and scaling the codebase so that it could be adapted for various use cases. 

“Open-source and open-technology have universal benefits. Meta is seeding the PyTorch community with a state-of-the-art RecSys package, with the hope that many join in on building it forward, enabling new research and helping many companies. The team behind TorchRec plan to continue this program indefinitely, building up TorchRec to meet the needs of the RecSys community, to welcome new contributors, and to continue to power personalization at Meta,” the engineers wrote.

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
