If you create your modern, brand-new page in a well-known asp.net mvc, sooner or later you will need an asynchronous code. The obvious choice is (or was?) A jquery. The problem is that despite being a powerful library, jquery requires quite a lot of coding to create even basic stuff. Our team needed a 2-way-binding, easy-to-use, well-documented substitution to jquery. Finally – we have chosen angularjs. However, in the .net world the mvc is an mpa (multi-page application) but angularjs is more into the s...

„The web has evolved. Finally, testing has too.” These words welcome us on the main page of the Cypress.io project, a new framework used to create the E2E tests in web applications. In my opinion, this statement is extremely accurate, and I would like to explain why I believe so.

One of the most important things during a penetration test is to gain access to administrator account. If the application (for example webserver) is well configured, it is most often run with limited user rights, only able to run a specific application. When we can get low privileges access to the server using some vulnerability, the next step is to get higher permissions to read important files, continue network exploration etc. To do this, we must use the privilege escalation technique.
If you want to assure that your data is secure “at rest”, in 2018, you have a bunch of widely known and well-tested industry standards available on the market – such as symmetric/asymmetric cryptography, data vaults like keychain etc. But all these ideas struggle from threat called a single point of failure – if your master key is accessed by anyone, all data can be accessed in unencrypted form. How to mitigate this issue? Here is where Shamir’s Secret Sharing Scheme (referred later as SSSS) come into use.
Git is simple but different – it is probably the most popular version control system (vcs) used in it projects around the world. It is also very often misused because although it is very similar to other vcss at the api level, it is very different underneath. Let’s take a look at the nuts and bolts of git to understand it better and, as a result, to use it properly and effectively.

Security headers are a subset of http response headers that, when sent by the server, allow the web application to tell the web browser to enable or configure certain security-related behaviours. The article presents a list of the most important Security Headers, shows their impact on web application security and provides resources that can be useful in the implementation of best practices in your own application.
Internet of Things happens to be a buzz-word that is often overused by marketing guys to boost profits by branding their product with labels such as ‘smart’ or ‘intelligent’, but what it really is. Why is IoT so popular? Let’s take a look at the technical aspects of that phenomenon.

Recently I have switched from using C# to Java at work. This is a move that bewilders some people. I’ve used .NET at work for over 6 years and a little more before that, so it’s understandable that going for something different after so much time raises eyebrows. In this short article I’ll try to explain my rationale behind doing so. I’ll also describe the process itself. Bear in mind that, given the topic, many things that you’ll read are my personal opinions or speculations.

When I first heard of functional programming (FP) I thought it’s another over-hyped thing that no one needs. I lived in my happy object-oriented world and didn’t think that there is something I should change. It wasn’t until I saw very convincing video where Uncle Bob described why FP is so important.
For the last 2 years Angular Team at Google, with huge support of the community, has been working on a new Angular framework. It has been completely rewritten with better performance and ready to use even outside the browser. In this article I want to introduce you to the basics of Angular 2+; we will build a small web application using angular-cli tool.

This is a story of a bug I had an opportunity to fix in the ancient times of node.js 0.10. The new and shiny node.js 0.12 was still just glimmering somewhere on the horizon, we were still young and beautiful. Some of us, at least. Let me take you on an adventure through time and space. Hopefully, there will be some learning involved along the way. So hop on the magic school bus and we’re off!

Code review is an important part of development process. Various teams use different styles from “over the shoulder” to the ones based on tools like Gerrit. However, more and more Git servers (like GitLab) give merge request functionality, which makes incorporating code review process easier.

The era of big data is here and now. How to efficiently train support vector machines from massively large real-life datasets?
The difference between what a customer really wants and what a development team thinks is expected can lead to real troubles. The Three Amigos helps to avoid such situations.
Today applications need to be more and more asynchronous and process more information in parallel. Every programming language has its own way of dealing with asynchronous programming. Some are designed for such purposes (like Erlang) but the others, more popular ones, are not. Is there no hope for Java, .Net or JavaScript developers? I think there is.
Inspiration to writing this article has been excerpted from the lecture “Like a Panda: Flow with Bamboo” led by Jonathan Doklovic, one of Atlassian’s employee, during Atlassian Summit 2013. That lecture described potential of building and deploying feature branches. Such functionality is offered by Bamboo – software released by Atlassian itself.
This post describes how to minimize overhead when developing systems with microservices architecture, especially as it comes to development and deployment. Some time ago, we published similar post about solving this problem in Microsoft and Azure world. This time we will focus on AWS, Java, Spring Boot, Docker and some useful open source libraries from Netflix.
