Angular*Node.JS*Open source*ReactJS*VueJS*
JavaScript developers, I am working on an exciting opensource project pursuing two goals:

  1. Learning best practices in JavaScript/NodeJS
  2. Helping developers and myself to develop and launch MVPs to validate ideas quickly.

As developers, we have tons of ideas and would be awesome to have a simple tool to scaffold a secure project quickly, add a couple of forms, some project specific logic, and here you go — deploy and test your idea.

WAF through the eyes of hackers

Digital Security corporate blogInformation Security*
Today we’re going to talk about one of the modern security mechanism for web applications, namely Web Application Firewall (WAF). We’ll discuss modern WAFs and what they are based on, as well as bypass techniques, how to use them, and why you should never entirely rely on WAF. We’re speaking from the pentesters’ perspective; we’ve never developed WAFs and only collected data from open sources. Thus, we can only refer to our own experience and may be unaware of some peculiarities of WAFs.

Open source tool for intent-based search quality validation

Search engine optimization*Development for e-commerce*IT systems testing*
No matter how cool your search solution is, without a reliable way of testing it you will not be able to do any improvement without breaking something valuable.

Even a tiny increase in overall search result quality might have a noticeable effect on conversion rate. Naturally, you can use exit-rate to judge if your search needs improvements and do required adjustments, but will you be able to make sure those changes are safe? What if improved relevancy for a specific category breaks search for several other categories?

Moreover, high exit-rate means no matter what you are going to do, the problem has taken place, so dozens of customers already didn’t manage to find what they were up to. Basically, the only way to proceed is to have a reliable search quality validation approach.

Build tools in machine learning projects, an overview

Reading time12 min
Views3.3K
Machine learning*Build automation*
I was wondering about machine learning/data science project structure/workflow and was reading different opinions on the subject. And when people start to talk about workflow they want their workflows to be reproducible. There are a lot of posts out there that suggest to use make for keeping workflow reproducible. Although make is very stable and widely-used I personally like cross-platform solutions. It is 2019 after all, not 1977. One can argue that make itself is cross-platform, but in reality you will have troubles and will spend time on fixing your tool rather than on doing the actual work. So I decided to have a look around and to check out what other tools are available. Yes, I decided to spend some time on tools.

This post is more an invitation for a dialogue rather than a tutorial. Perhaps your solution is perfect. If it is then it will be interesting to hear about it.

In this post I will use a small Python project and will do the same automation tasks with different systems:


There will be a comparison table in the end of the post.

Microsoft corporate blog.NET*Visual Studio*

Visual Studio’s project templates enable you, the developer, to create multiple similar projects more efficiently by defining a common set of starter files. The project templates can be fully customized to meet the needs of a development team, or a group, and can be published to the Visual Studio Marketplace for others to download and use too! Once published, developers can install and access the template through Visual Studio’s New Project Dialog.


The newly designed New Project Dialog for Visual Studio 2019 was built to help developers get to their code faster. Using a search and filter focused experience, we are aiming to provide better discoverability for specific templates to start your application development

This article will show you the basics of types internals, as of course an example in which the memory for the reference type will be allocated completely on the stack (this is because I am a full-stack programmer).



Disclaimer


This article does not contain material that should be used in real projects. It is simply an extension of the boundaries in which a programming language is perceived.

Before proceeding with the story, I strongly recommend you to read the first post about StructLayout, because there is an example that will be used in this article (However, as always).

Microsoft corporate blogCloud services*Cloud computing*Microsoft Azure*

As more organizations are delivering innovation faster by moving their businesses to the cloud, increased security is critically important for every industry. Azure has built-in security controls across data, applications, compute, networking, identity, threat protection, and security management so you can customize protection and integrate partner solutions. 


We keep investing in security and we are excited to share exciting updates this week at Hannover Messe 2019. We are excited to announce that Dedicated Hardware Security Module Service (HMS) in UK, Canada, and Australia, Azure disk encryption support for Virtual Machine Scale Sets (VMSS) are generally available. Also Advanced Threat Protection for Azure Storage, the Regulatory Compliance Dashboard, and support for virtual machine sets are now generally available as part of Azure Security Center.

New feature in Git 3: closures

Reading time3 min

Git*
Translation

Git is a popular version control system. In Git, an atomic change of one or several files is called a commit, and several consecutive commits are combined into a branch. Branches are used to implement new ideas (features).



It happens that the idea is a dead end and the developer has turned the wrong way, so he needs to roll back to the original version. He should forget about the new branch, switch to the main dev or master branch and continue working. In this case, the "scion" will hang forever, as well as the desire to remove it. But how to remove the part of the history? This branch shows the efforts of the hard-working programmer, even if in vain. So it will be easier to report to the boss, because an unsuccessful result is also a result!


I hasten to rejoice that Git developers are going to introduce a new command to close such "homeless" branches in the third version. The current version is 2.21.0.


How to use this command, what benefits does it give and what do IT companies think? The article answers these and other questions.

We've already discussed PostgreSQL indexing engine and interface of access methods, as well as hash index, one of access methods. We will now consider B-tree, the most traditional and widely used index. This article is large, so be patient.

Btree


Structure


B-tree index type, implemented as «btree» access method, is suitable for data that can be sorted. In other words, «greater», «greater or equal», «less», «less or equal», and «equal» operators must be defined for the data type. Note that the same data can sometimes be sorted differently, which takes us back to the concept of operator family.

Microsoft corporate blog.NET*ASP*Programming*

We are now publishing .NET Core container images to Microsoft Container Registry (MCR). We have also made other changes to the images we publish, described in this post.


Important: You will need to change FROM statements in Dockerfile files and docker pull commands as a result of these changes. 3.0 references need to be changed now. Most 1.x and 2.x usages can be changed over time. The new tag scheme is decribed in this post and are provided at the microsoft-dotnet-core repo, our new home on Docker Hub.


Summary of changes:


  • .NET Core images are now published to Microsoft Container Registry.
  • Updates will continue to be published to Docker Hub, for .NET Core 1.x and 2.x.
  • .NET Core 3.0 will only be published to MCR.

Development of communication systems*The future is here


Fiber-optic cables are a great way to bring high-speed Internet right to your home or office. But even in large cities not everyone can enjoy the benefits of it, since apartments far away from everyone, or low-population districts far from downtown, are very reluctantly served by ISPs.

And then there’s small towns and villages, far away from the main Internet “highways”. In poorer countries, Internet is often slow and expensive even in large population centers, while villages are often left without a connection for years. To connect them to the World Wide Web takes the resources of not just normal ISPs, but telecom giants. Solar-powered drones with networking equipment, weather balloons, satellites and other similar projects are not just science fiction, but a reality today (or in the near future). But who’s closer to launch and who’s lagging behind? Let’s find out.

React Code Splitting in 2019

JavaScript*ReactJS*

It's 2019! Everybody thinks they know code splitting. So - let's double check!



What does code splitting stand for?


In short – code splitting is just about not loading a whole thing. Then you are reading this page you don't have to load a whole site. When you are selecting a single row from a database – you don't have to take all.
Obvious? Code splitting is also quite obvious, just not about your data, but your code.

Developing A Basic Darts Scoreboard App

Reading time5 min

Games and game consoles
Darts is one of the most popular games in the world. It’s a good way to challenge your friends and family members, putting your accuracy to the test. However, keeping score can be a challenge. People often needed to rely on pen and paper, tallying up the score by hand. Thankfully, modern technology can help solve this challenge. An app makes calculating the winner easy, giving you more time to focus on the game.

If you’re planning on designing one of these apps, there are a few steps that you’ll need to follow.

Set-Up Players


The first thing that you need to decide is who will be playing the game. This will require the player to enter the input. If more than one person is playing, they will need to enter their names. This will allow the app to keep the scores separate.
