The process of achieving a meaningful goal

Some time ago, I told you my story of becoming a better player in League of Legends. There was some kind of flaw in my skills and I decided to change that. So I started watching some YouTube videos about becoming a better LoL player.

But the key to mastering that game was not in studying all sorts of fancy game mechanics or memorizing the items to buy for each hero. It was in adopting a mindset of always blaming yourself instead of your team for the mistakes you all make. That helped me skyrocket my overall gameplay and after a while, I was able to climb the ranked ladder of the game and I moved from the weakest division to being among the top 5% of the players in my server.

This achievement was quite improbable at first. So since then I had been wondering – how could adopting such a philosophy make me a better player in the game? Why didn’t all the mechanics I had watched help me, but instead it was this simple thought of always blaming yourself that released the handle of my potential?

Understanding Standard Input and Output


This article is part of the sequence What you won’t learn in the basics courses aimed at eager people striving to gain a deeper understanding of programming and computer science.

Somewhere in the first lectures of a programming basics course, we are shown how to take input and show output on the terminal. That’s called standard input/output or just Standard IO for short.

So, in C# we have Console.WriteLine and Console.ReadLine.
In C++, we have cin and cout.

All these things are associated with the topic of Standard IO. And what they tell us is that the standard input is the keyboard and the standard output is the screen. And for the most part, that is the case.

But what we don’t get told is that the Standard IO can be changed. There is a way to accept input from a file and redirect output to another file. No, I’m not talking about writing code to read/write files. I am talking about using the Standard IO for the job, via the terminal.

Keeping yourself organized in today’s world

Somewhere around the start of the school year, we had to prepare our student books. We had to get some signatures, some photos and getting all the needed data on it. I was always the last one to do that. One particular year, my class teacher gave me my students book, after the head teacher had signed it, and said: “Don’t lose it this time”.

“Of course I won’t” I said confidently and went back to my desk. One week later, a man came to school and said he had found a lost students book. The teacher wasn’t surprised when he found out it was mine. The funny thing is that only when I received it did I realize I had lost it in the first place.

As time passed, I finished school, learned new things and advanced myself greatly. But one thing did not change – my carelessness.

But now, I ought to be more responsible if I am to be taken seriously as a professional. That is why,  I have discovered a framework which has helped me transition from a careless boy to a responsible person.

The productive developer

When I started my first job, I was really excited as I realized that this is the point at which I start programming professionally. But once I got to actual work, there was some kind of flaw in my performance. I was trying to do my tasks from the moment I came until I finished. But while doing so, I constantly distracted myself with social media. And when I got assigned a huge task, I felt overwhelmed and it was extremely hard to even start doing it, just because I realize how much work I have to do in order to finish it. I just couldn’t keep myself productive.

But at one point, I realized that my approach was totally wrong.  Today, I will show you a system, which has become an extremely useful tool for me, that aids me at feeling satisfied with my work and delivering maximum output.

What you don’t know about sorting algorithms


This article is part of the sequence What you won’t learn in the basics courses aimed at eager people striving to gain a deeper understanding of programming and computer science.

Last time, we delved into bitwise operations. This time, we will look at a more high level computer science concept – algorithms.

When we first get introduced to algorithms, we normally start with learning sorting algorithms. In comparison to other algorithms, they are easier to grasp. And if we pay attention in class, we will do a good job at understanding them. However, what we don’t learn in these classes is when can they be useful.
