Botnets are watching you closely

Information security is paramount in our digital world. Whether it is your work project or your personal life, nothing is insured against black-hat attacks. In this article, I will tell you about some of the common attack types so you can be prepared.

Most people think they need not bother about cyber attacks. Really, if you look at it, why would anyone bother cracking your bank account for whatever saving you might have when they could hack a bank, or say Pentagon?

In practice, it is a bit more complicated than that. While banks, no…

Much like Fidonet and floppy disks, it is going to die fast and very soon

Now, I assure this is not a clickbait title. I really think that we are the last generation to make use of internet in its current iteration, and will convince you in a few paragraphs.

It is very hard to imagine our lifes without internet. It had been there from day one (for some of us) and grew old along. Now it is no longer a defence systems network, it is no longer a scientific research network, but rather The Network. …

React is an extremely easy to use frontend library. It allows prototyping and iteration at a neck-breaking speed. But, when developing large-scale production apps. it is important to carefully design the architecture and keep the design clear and simple. In this article, I will go into some of the tools and principles you can use to architect your React projects.

Why is Architecture So Important?

It is easy to gloss over many architecture decisions and principles when starting from the ground up. By the end of the sprint, you already have working authentication, homepage and stakeholders are happy. …

No more frustration moving JAR files

If you are working with Java projects, you will most likely have to deal with Maven. Maven is a project management tool, used as an industry standard for medium to large scale Java applications. In this post, I will teach you to create production artifacts of multi-module Maven projects using the assembly plugin.

Initial project structure

For the purposes of this article, I will assume a very bare-bones project in Maven. We will have 4 modules: root, which is the main (container) module, common, which is used by other modules, app, the app itself, and tools. We…

Flutter is a cross-platform application development framework. But no application is really complete without a comprehensive testing suite. In this article, I will tell you the basic principles of both unit- and widget-testing Flutter apps as well as mocking dependencies.

Why Test?

Testing is vital when developing any serious software project. With a good test suite in place, you can make changes to any part of the code without worrying about if that is going to break anything. You can run tests any time and get an answer within minutes if the system is working correctly.

If you, as a developer, do…

Catch bugs before you even write them

Python is a multi-purpose language that is used for everything backend. In this article, I will teach you to perform basic unit testing in Python, how to mock modules, and make sure your code is clean.

What is Unit-testing?

Unit-testing is one of the ways to test your code. Other ways include functional testing, integration testing, regression testing and so on. Testing is vital to any larger codebase, as it lets you iterate and perform changes quickly, without worrying to much about what is going to break.

Unit-testing is the lowest testing method on the abstraction…

With Python becoming more and more popular lately, many of you are probably undergoing technical interviews dealing with Python right now. In this post, I will list ten advanced Python interview questions and answers.

These can be confusing and are directed at mid-level developers, who need an excellent understanding of Python as a language and how it works under the hood.

What Are Nolocal and Global Keywords Used For?

These two keywords are used to change the scope of a previously declared variable. nolocal is often used when you need to access a variable in a nested function:

def func1(): 
    x = 5
    def func2(): 
        nolocal x 
        print(x)…

Manage your resources like a pro

Python is a particularly clean and sugary language, thanks to its many convenience features. In this post, I will go into context managers in Python, how to use them, where to find them, and how to write your own ones.

Why do we need Context Managers?

Context managers are most often used when we are talking about resources. For example, reading/writing from files. Examine this simple snippet:

f = open('log.txt', 'w') 
f.write('hello world') 
f.close()

All this code does is open the log.txt for writing and writes hello world in it. Simple enough. But suppose for a minute, that the code…
