PHP, or hypertext preprocessor, is an open-source server-side scripting language. It’s extremely popular, too — almost 80% of all websites were using PHP as of October 2018.

But how do you know which PHP framework is right for you?

In this article, a DIRTY, unsafe, unstable and scary <em>eval</em> method will be described. So, if you are uncomfortable with that, stop reading right now.

First off, some issues with convenience remained unresolved: in code sent to web web workers, closure can't be used.

All of us like new technologies, and all of us like new technologies to be convenient to use. However, it's not exactly the case with web workers. web workers accept files or links to files, which isn't convenient. It would be good to be able to put any task into web workers, not just specifically planned code.

What do we need to make web workers more convenient to operate? I believe, it's the following:

• A possibility to launch in web workers any code at any moment
• A possibility to send to web workers complicated data (class instances, functions)
• A possibility to receive a promise with a reply from a web worker.

I don’t care what your dragon’s said, it’s a lie. Dragons lie. You don’t know what’s waiting for you on the other side.

We’re excited to announce the preview availability of the new Azure IoT Edge Tools Extension (Preview) for Visual Studio 2019. The extension provides a rich set of functionalities to support development of IoT Edge solutions with Visual Studio 2019:

Since I’ve been working with the community on porting desktop applications from .NET Framework to .NET Core, I’ve noticed that there are two camps of folks: some want a very simple and short list of instructions to get their apps ported to .NET Core while others prefer a more principled approach with more background information. Instead of writing up a “Swiss Army knife”-document, we are going to publish two blog posts, one for each camp:

• This post is the simple case. It’s focused on simple instructions and smaller applications and is the easiest way to move your app to .NET Core.
• We will publish another post for more complicated cases. This post will focus more on non-trivial applications, such WPF application with dependencies on WCF and third-party UI packages.

If you prefer watching videos instead of reading, here is the video where I do everything that is described below.

Since its completion more than 675 years ago, the medieval cathedral of Notre-Dame has captivated millions of people with its incomparable beauty. From its legendary stained glass rose window to its towering spire, it’s widely regarded as one of the most stunning examples of medieval architecture in history.

Some days ago we announced the preview of Windows Vision Skills, a set of NuGet packages that make it easy for application developers to solve complex computer vision problems using a simple set of APIs.

From idea to implementation: modifying the existing elliptic curve signature scheme to be deterministic and providing functions on it to obtain verifiable within the blockchain pseudorandom numbers.

The Time Travel Debugging (TTD) preview in Visual Studio Enterprise 2019 provides the ability to record a Web app running on a Azure Virtual Machine (VM) and then accurately reconstruct and replay the execution path. TTD integrates with our Snapshot Debugger offering and allows you to rewind and replay each line of code however many times you want, helping you isolate and identify problems that might only occur in production environments.

Google shut down their social media platform Google+ on April 2, 2019. It’s hard to find some technical article that hasn’t mentioned the end of Google’s social network era. But, a high level of consistency in connectivity within services of the company had received scant attention. In this article I would like to share my thoughts on the internal way of Google services consistency and what it means for Google API users when it comes to a Google+ shutdown.

In this post we'd like to share an interesting way of dealing with configuration of a distributed system.
The configuration is represented directly in Scala language in a type safe manner. An example implementation is described in details. Various aspects of the proposal are discussed, including influence on the overall development process.
