SD Times news digest: Rust 1.51 released, Amazon Lookout for Metrics, and D language 2.096

The latest Rust version (1.51) presents some of the largest additions to the Rust language and Cargo in a while, while stabilizing an MVP of const generics and a new feature resolver for Cargo.

Const Generics MVP is a powerful new feature that enables developers to write reusable code with no runtime overhead and now the new version makes it easier to be generic over the values of those types. This change lets developers have their own array struct that’s generic over its type and its length.

For Cargo, the release adds a new resolver option in Cargo.toml, where developers can set resolver=”2″ to tell cargo to try a new approach to resolving features. 

Additional details are available here.

Amazon Lookout for Metrics now available
Amazon Lookout for Metrics uses machine learning to detect and determine the root cause of anomalies in business metrics. 

Traditional rule-based methods for identifying anomalies are usually manual and they result in either false alarms or missed anomalies if the ranges are set too narrow or wide, respectively, according to the company. 

Lookout for Metrics now provides all developers with the technology that Amazon uses in its own store. It’s also capable of connecting to 19 popular data sources.

D language 2.096
 The updated version includes many notable improvements to experimental C++ header generation, support for DWARF debug info and changes to plain synchronized statements to use runtime-allocated mutexes fixes a critical issue.

This release introduces three new aliased types that are automatically configured at compile-time to be ABI compatible with C’s _Complex and should be used in place of the built-ins when interacting with C or C++.

Now, newly written code makes use of copy constructors rather than postblits, but postblits are not deprecated and remain in the language, whereas previously, priority was given to postblit when both a postblit and a copy constructor were present. 

Additional details are available here.

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
