اضافه شدن CSSNestedDeclarations به استاندارد CSS
CSS nesting improves with CSSNestedDeclarations

To fix some weird quirks with CSS nesting, the CSS Working Group resolved to add the CSSNestedDeclarations interface to the CSS Nesting Specification. With this addition, declarations that come after style rules no longer shift up, among some other improvements.
These changes are available in Chrome from version 130 and are ready for testing in Firefox Nightly 132 and Safari Technology Preview 204.

استفاده رایگان از Xamarin در تمامی نسخه‌های Visual Studio

 In short, we’re making Xamarin’s cross-platform tools available in Visual Studio, from Community up through Enterprise at no additional cost and we’re open-sourcing the Xamarin SDK – the core of the Xamarin toolchain. In addition, we’re making Xamarin’s services (for example, Test Cloud and Xamarin University) available along with the existing Microsoft mobile DevOps capabilities.

استفاده از jspm در ویژوال استدیو 2015

In a nutshell: jspm combines package management with module loading infrastructure and transpilers to provide a magical experience. You can write code using today’s JavaScript, or tomorrow’s JavaScript (ES6), and use any type of module system you like (ES6, AMD, or CommonJS). jspm figures everything out. By integrating package management with a smart script loader, jspm means less work for us.

بررسی معماری Stack Overflow

In the recent interview with Scott Hanselman, Roberta Arcoverde, Head of Engineering at Stack Overflow, revealed the story about the architecture of Stack Overflow. They handle more than 6000 requests per second, 2 billion page views per month, and they manage to render a page in about 12 milliseconds. We imagine they use a microservice solution running in the Cloud with Kubernetes.
