Microbenchmark testing Python, Numba, Mojo, Dart, C/gcc, Rust, Go, JavaScript, C#, Java, Kotlin, Pascal, Ruby, Haskell performance in Mandelbrot set generation 

Benchmarking several languages/tools with Mandelbrot set generation. 1-to-1 translation of code from one language to another. No SIMD, no multithreading (except prange() trick with Numba), no tricks (e.g. skipping sqrt), a bare minimum of language specific adjustments to make the code nicer while keeping all loops and operations in place. 

The Open XML SDK provides tools for working with Office Word, Excel, and PowerPoint documents. It supports scenarios such as:

• High-performance generation of word-processing documents, spreadsheets, and presentations.
• Document modification, such as adding, updating, and removing content and metadata.
• Search and replace content using regular expressions.
• Splitting up (shredding) a file into multiple files, and combining multiple files into a single file.
• Updating cached data and embedded spreadsheets for charts in Word/PowerPoint. 

Issues Fixed in 15.9.23

• Fixed C++ compiler bug for proper folding of inline variable dynamic initializers. Ported from the VS 2019 16.0 release.
• Security improvements in vctip.exe.
• A change to enable Enterprise IT administrators and deployment engineers to configure tools like Microsoft Update client & SCCM to determine applicability of VS2017 updates hosted on Microsoft Update Catalog & WSUS.

Security Advisory Notices

• .NET Core Denial of Service Vulnerability 

If you write copious amounts of CSS, a pre-processor can greatly decrease your stress levels and save you a lot of precious time. Using tools such as Sass, Less, Stylus or PostCSS makes large and complicated stylesheets clearer to understand and easier to maintain. Thanks to features like variables, functions and mixins the code becomes more organized, allowing developers to work quicker and make less mistakes. 

Would you like help creating single-page applications (SPAs)? Maybe you've worked with tools like jQuery and AJAX, but what about Ember? With a simple syntax and an emphasis on reuse and components, this JavaScript framework can make it very easy to create interactive pages. Get a close look at Ember, plus lots of demos and practical tips with popular experts Adam Tuliper and Christopher Harrison, in this three-hour event for the MVA community
