ASP.NET Core provides better support for clean, testable, maintainable architectures than any of its predecessors. Learn the underlying principles that apply to project/solution organization, how best to arrange your projects to support clean code, and how to refactor existing solutions toward this architecture. Examples will use ASP.NET Core but the principles covered apply to all languages and platforms.  

A simple utility to execute a callback when a webfont loads.  Demo

This uses the CSS Font Loading Module when available (currently in Chrome 35+ and Opera 22+). When that isn’t available, it uses a very similar approach to the one used in the TypeKit Web Font Loader (which is currently 7.1KB GZIP).

Basically, it creates an element with a font stack including the web font and a default serif/sans-serif typeface. It then uses a test string and measures the dimensions of the element at a certain interval. When the dimensions are different than the default fallback fonts, the font is considered to have loaded successfully.

If you’d like a full polyfill for the CSS Font Loading Module, follow along with Bram Stein’s Font Loader. I believe the specification has changed since he launched this polyfill, but he’s working on an updated version. 

Akka.NET is an open-source actor model framework written exclusively for Microsoft.NET in C# and compatible with .NET Core. It simplifies the building of scalable, concurrent, high-throughput, and low-latency systems, making life for software developers a bit easier. Zoran Maksimovic's Akka.NET Succinctly will show readers what an actor model is and how to work with actors in Akka.NET, taking them from an actor's lifecycle through to unit testing.

In addition to bug fixes and foundation work for larger features, this preview includes updates to ensure that converters and comparers are handled by type mapping and to support using converters with value generators.  

- The OmniSharp server has been updated to Roslyn 2.3.0, which adds support for C# 7.1
- Update debugger to run itself on .NET Core 2.0-preview2 (target app can still use .NET Core 1.x).  

With millions of users, resulting in 75 billion package downloads per month, npm has undoubtedly been a huge success and npm 7 is now here (and will also come with Node.js 15.0 next week). Key features include workspaces, installation of peer dependencies, and support for yarn.lock.

Checked C is an extension to C that adds static and dynamic checking to detect or prevent common programming errors such as buffer overruns, out-of-bounds memory accesses, and incorrect type casts.  

it takes roughly 31 seconds to de-serialise the data from disk and another 3 1/2 minutes to process and sort it. At the end we are using roughly 4.5GB of memory.

As stated in this article, Windows 10, version 1909 is a scoped set of features for select performance improvements, enterprise features and quality enhancements. Developers should be aware of this release, but no action is necessary at this time.
