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.

In previous article we told a lot about security of ERP systems. Now we want to talk about ways to protect them.

According to Evans Data Corporation, there are 12 million developers in the world. About 350,000 of these software and mobile developers work and live in the UK including freelancers and IT employees.

How do you choose the best one among all this variety? The obvious answer — get going with a professional IT company. This will increase your chances to work with true professionals.

I’ve made my own research based on a variety of reliable resources like Google SERPs and user’s reviews, different independent media, including medium.com and aggregators, like businessofapps.com, Clutch, etc. and other independent sites. Based on the collected data, I’ve aggregated the total score for each of the 25 leaders, and here I represent a list of the winners: the top 5 software developers in the UK.

Last week, Microsoft held its Build 2019 conference at the Washington State Convention Center in Seattle. Build is a large event with several thousand people from around the world attending to learn all about the current, newest, and future developer-oriented tech coming from Microsoft.

We had the pleasure of meeting so many of you at our booth and answering all your questions!

Back in 2007, Brian Chesky and Joe Gebbia shared a room in San Francisco and were unable to pay rent on time. As a way out, they decided to turn their living space into a simple bed-and-breakfast hotel to get some money from travelers. If you love traveling i can advice you Travel news site. A year later, the venturers launched a website which evolved into the most famous peer-to-peer renting technology service called Airbnb.

 Now, the company has 3,100 employees and generates insane revenues for its founders. The statistics say that Airbnb has 150 million registered users, 3 million hosts, and 4 million listed offers. The service covers 80,000 cities in 190 countries, and, interestingly, 50% of traffic comes from mobile applications.

  These figures are so impressive that you may also want to create your own Airbnb clone and become successful. But slow down. This story is already written; do you really need to create a marketplace similar to Airbnb?

Some days ago we announced improved Razor tooling support in Visual Studio Code with the latest C# extension. This latest release includes improved Razor diagnostics and support for tag helpers and Blazor apps.

Why is Elixir/Phoenix achieving such a high rate of adoption in the software development industry? What are the best use cases of this language? Are there any drawbacks when using it? We talked to Sergiy Kukunin, a full-stack developer at Spotlight and an Elixir expert, to find answers to these and other questions.

Earlier this week, we released Visual Studio 2019 version 16.1 Preview 1 (see release notes). It’s the first preview of the first update to Visual Studio 2019. If you’re not already set up to get preview releases, then please do that now. The preview channel installs side-by-side with the release channel and they don’t interfere with each other. I highly recommend all extension authors install the preview.

Got the 16.1 preview installed now then? That’s great. Here are some features in it you might find interesting.

If you use Habr, chances are, you’re conscious about privacy on the web. As governments and corporations tighten their grip on people’s online activities, the issue of keeping your browsing data to yourself becomes more and more relevant.

Numerous tech websites say VPN is no longer a geek-only thing, and regular people should use it, too (Fast Company, Mashable, PCMag). But as a tech-savvy person, you know there isn’t a service you can trust as much as the one you host and manage yourself.

With this post, you’ll deploy your own instance of Outline VPN on AWS.

We've already discussed PostgreSQL indexing engine, the interface of access methods, and three methods: hash index, B-tree, and GiST. In this article, we will describe SP-GiST.

SP-GiST

First, a few words about this name. The «GiST» part alludes to some similarity with the same-name access method. The similarity does exist: both are generalized search trees that provide a framework for building various access methods.

«SP» stands for space partitioning. The space here is often just what we are used to call a space, for example, a two-dimensional plane. But we will see that any search space is meant, that is, actually any value domain.

SP-GiST is suitable for structures where the space can be recursively split into non-intersecting areas. This class comprises quadtrees, k-dimensional trees (k-D trees), and radix trees.

Hello. This time we continue to laugh at the normal method call. I propose to get acquainted with the method call with parameters without passing parameters. We will also try to convert the reference type to a number — its address, without using pointers and unsafe code.

I’m going to have a guess and say that everyone whose friends or family have ever flown on a plane, have used Flightradar24 — a free and convenient service for tracking flights in real time.



In the first part the basic ideas of operation were described. Now let's go further and figure out, what data is exactly transmitting and receiving between the aircraft and a ground station. We'll also decode this data using Python.

• First of all, you can read this article in russian here.

One evening, I was reading Mastering regular expressions by Jeffrey Friedl , I realized that even if you have all the documentation and a lot of experience, there could be a lot of tricks developed by different people and imprisoned for themselves. All people are different. And techniques that are obvious for certain people may not be obvious to others and look like some kind of weird magic to third person. By the way, I already described several such moments here (in russian) .

For the administrator or the user the command line is not only a tool that can do everything, but also a highly customized tool that could be develops forever. Recently there was a translated article about some useful tricks in CLI. But I feel that the translator do not have enough experience with CLI and didn't follow the tricks described, so many important things could be missed or misunderstood.

Under the cut — a dozen tricks in Linux shell from my personal experience.

How often do you get to 404 pages? Usually, they are not styled and stay default. Recently I’ve found test.do.am which interactive character attracts attention and livens up the error page.

Probably, there was just a cat picture, then they thought up eyes movement and developer implemented the idea.Now user visits the page and checks out the effect. It’s cool and pleasant small feature, it catches, then user discusses it with colleagues or friends and even repeats the feature. It could be this easy, if not:

A few months ago I worked with a customer on how a team should evaluate the security of their Azure implementation. I had never done a pentest(extensive security testing)on an Azure application before, so these ideas were just the thoughts off of the top of my head at that time based on my experience in security.

Matt Burrough’s book, Pentesting Azure Applications, goes even deeper and it is a must-read for security experts focused in Cloud Computing, I’m reading it right now.

Below I share with you these pre-book thoughts, and will compare them in a future article with the ones I will learn — or confirm — after reading Matt's book.
