In a previous Remote SSH blog post, we went over how to set up a Linux virtual machine and connect to the VM using the Remote — SSH extension in Visual Studio Code. In this blog post, we'll go into some tips and tricks that you can use to get the most out of your remote setup.

When talking about "bad code" people almost certainly mean "complex code" among other popular problems. The thing about complexity is that it comes out of nowhere. One day you start your fairly simple project, the other day you find it in ruins. And no one knows how and when did it happen.

But, this ultimately happens for a reason! Code complexity enters your codebase in two possible ways: with big chunks and incremental additions. And people are bad at reviewing and finding both of them.

With October release of the Python extension, we’re excited to announce the support of native editing of Jupyter notebooks inside Visual Studio Code! You can now directly edit .ipynb files and get the interactivity of Jupyter notebooks with all of the power of VS Code.

You can manage source control, open multiple files, and leverage productivity features like IntelliSense, Git integration, and multi-file management, offering a brand-new way for data scientists and developers to experiment and work with data efficiently. You can try out this experience today by downloading the latest version of the Python extension and creating/opening a Jupyter Notebook inside VS Code.



Since the initial release of our data science experience in VS Code, one of the top features that users have requested has been a more notebook-like layout to edit their Jupyter notebooks inside VS Code. In the rest of this post we’ll take a look at the new capabilities this offers.

We are pleased to announce that the October 2019 release of the Python Extension for Visual Studio Code is now available. You can download the Python extension from the Marketplace, or install it directly from the extension gallery in Visual Studio Code. If you already have the Python extension installed, you can also get the latest update by restarting Visual Studio Code. You can learn more about  Python support in Visual Studio Code in the documentation.  

In this release we addressed 97 issues, including native editing of Jupyter Notebooks, a button to run a Python file in the terminal, and linting and import improvements with the Python Language Server. The full list of enhancements is listed in our changelog. 

Anyone who uses Git knows that it has a steep learning curve. We’ve learned from developers that most people tend to learn from a buddy, whether that’s a coworker, a professor, a friend, or even a YouTube video. In GitHub Desktop 2.2, we’re releasing the first version of an interactive Git and GitHub tutorial that can be your buddy and help you get started. If you’re new to Desktop, you can download and try out the tutorial at desktop.github.com.

On October 7, 2019, Apple released a new version of its Mac operating system, macOS Catalina. Version 10.15 contains many changes and improvements. One of the significant is the complete phasing out of 32-bit applications. As a developer of such macOS apps, what can you do? That's right, port the app to the 64-bit platform. Will the application work properly from the first attempt? Perhaps, it's possible. Depends on the complexity and amount of the code. But most likely, developers will face a lot of non-obvious errors, which can previously detected using PVS-Studio.

This article we are going to learn is: How to install and run the swoft websocket server.

This article is one of a series of articles on the Swoft WebSocket Server. Let's learn about Swoft!

What is Swoft?

Swoft is a PHP high performance microservice coroutine framework. It has been published for many years and has become the best choice for php.

It can be like Go, built-in coroutine web server and common coroutine client and is resident in memory, independent of traditional PHP-FPM.

There are similar Go language operations, similar to the Spring Cloud framework flexible annotations.

Through three years of accumulation and direction exploration, Swoft has made Swoft the Spring Cloud in the PHP world, which is the best choice for PHP's high-performance framework and microservices management.

Styles, by default, in wpf, in Avalonia, are neutral, and far from always suitable for the tasks we need. In this article, I would like to talk about the basics of working with styles and show a couple of interesting examples.

The web development arena is moving at a fast pace and has reached an advanced stage today. Python and Javascript making some significant contributions for almost three decades. Now, being a developer or a business if you are planning to pick one of these, then it’s going to be tough just because both are too good to avoid. Hence, this brings up the topic ‘Python vs JavaScript: Which One Can Benefit You The Most?’

These two languages are supported by various trending web frameworks and libraries which are the real game-changers. The introduction of these frameworks and libraries to the web ecosystem has brought new paradigms, traditional notions, and standards of software development.

Introduction

Earlier, I have introduced the Ontology Smart Contract in
Part 1: Blockchain & Block API and
Part 2: Storage API
Now when you have an idea about how to call the relevant API for persistent storage when developing Python smart contract on Ontology, let’s go on to Runtime API (Contract Execution API). The Runtime API has 8 related APIs that provide common interfaces for contract execution and help developers get, convert, and validate data. Here’s a brief description of these 8 APIs:

This is an official tutorial published earlier on Ontology Medium blog
Excited to publish it for Habr readers. Feel free to ask any related questions and suggest a better format for tutorial materials

Foreword

Earlier, in Part 1, we introduced the Blockchain & Block API of Ontology’s smart contract. Today we will discuss how to use the second module: Storage API. The Storage API has five related APIs that enable addition, deletion, and changes to persistent storage in blockchain smart contracts. Here’s a brief description of the five APIs:


Have you thought about the influence of the nearest metro to the price of your flat? 
What about several kindergartens around your apartment? Are you ready to plunge in the world of geo-spatial data?

Sometimes we don’t understand how the regular expression that we have composed works and want to check. There are many applications like regex101.com or vs code. I wanted to add one more to this list.

In this article we will see how you can wrap Regex in cross-platform graphics and create a simple application for testing regular expressions.

Our support chats and some other indirect signs showed that there are many students among our free users. Here's the reason: PVS-Studio is now more often used by professors in courses related to software development. We are very pleased with this, and we decided to write this small article to fall under notice of other teachers. We are pleased that students become acquainted with the methodology of static code analysis in general and the PVS-Studio tool in particular. Our team will try to contribute to this trend.

Probably the largest hurdle when learning any new programming language is simply knowing where to get started. What’s important? What do I need to know to be proficient? It’s hard to follow docs when you’re not even sure what you’re reading.

You might be taking a look at Python. Maybe you’re drawn because of its popularity. Maybe you’re drawn to its flexibility. With Python you can create solutions of all shapes and sizes. You can dig into web development. Simplify your life through automation. Or maybe begin building the future with machine learning.

Picking up a new language is a common situation for modern-day developers. The days of going your entire career focused on one language are long since gone.

Fortunately, concepts typically don’t change as you move from one programming language to the next. Sure, the syntax might be different, but an if statement is still an if statement even when it’s written using { } or End If. So, we don’t need to learn how to program, but rather how to program in a new language.

This is why Susan and I created this series of videos! You might know how to write code, for example in JavaScript, Java or C# (or COBOL, or Bash, or… it doesn’t matter, really). Maybe you learned in a college course, online, or reading a book. So, you don’t need to be taught what an if statement is, but rather what an if statement looks like in Python.

Quintet is a way to present atomic pieces of data indicating their role in the business area. Quintets can describe any item, while each of them contains complete information about itself and its relations to other quintets. Such description does not depend on the platform used. Its objective is to simplify the storage of data and to improve the visibility of their presentation.



We will discuss an approach to storing and processing information and share some thoughts on creating a development platform in this new paradigm. What for? To develop faster and in shorter iterations: sketch your project, make sure it is what you thought of, refine it, and then keep refining the result.

The quintet has properties: type, value, parent, and order among the peers. Thus, there are 5 components including the identifier. This is the simplest universal form to record information, a new standard that could potentially fit any programming demands. Quintets are stored in the file system of the unified structure, in a continuous homogeneous indexed bulk of data. The quintet data model — a data model that describes any data structure as a single interconnected list of basic types and terms based on them (metadata), as well as instances of objects stored according to this metadata (data).

We are pleased to announce that the September 2019 release of the Python Extension for Visual Studio Code is now available. You can download the Python extension from the Marketplace, or install it directly from the extension gallery in Visual Studio Code. If you already have the Python extension installed, you can also get the latest update by restarting Visual Studio Code. You can learn more about  Python support in Visual Studio Code in the documentation.

This was a short release where we closed 35 issues, including improvements to the Python Language Server and to Jupyter Notebook cell debugging, as well as detection of virtual environment creation. The full list of enhancements is listed in our changelog. 

We are committed to building Visual Studio App Center for you. Thanks to you taking the time to request features via our Github repo, we are excited to announce that dark theme is available in App Center.

In the next few screens, you can get an idea of how App Center’s dark theme looks:

Cascadia Code is finally here! You can install it directly from the GitHub repository’s releases page or automatically receive it in the next update of Windows Terminal.

Wait, what’s Cascadia Code?

Cascadia Code was announced this past May at Microsoft’s Build event. It is the latest monospaced font shipped from Microsoft and provides a fresh experience for command line experiences and code editors. Cascadia Code was developed hand-in-hand with the new Windows Terminal application. This font is most recommended to be used with terminal applications and text editors such as Visual Studio and Visual Studio Code.
