Cosmonaut in a boatMy dear diary, today I …
About such scenario for the Warcraft 2 or 3 movie, I thought, or to say it more right – I dreamed, before the first Warcraft movie was released, which isn’t disappointed me, but also not amused a lot. That scenario, which plays in my head, for me feels much more exciting. And I decided to put it in the blog post. What are the chances, that even translated into English, that “scenario” would have some value? :)
In this final post in the series about my interview with X-Team, I will write about how it ended and will summarize my experience. Also, I will explain why I decided to dedicate so many posts about an interview with a company, which actually failed for me (not my fault!).
While working on my current project I was needed to generate a unique random string for an email confirmation. It’s a pretty common task and it has a bunch of simple solutions.
But I wanted it to be really random and flexible. I have ended with a helper with static functions which I want to share.
After buying a new laptop, I spent a lot of time with the Internet problem on Ubuntu. And I did manage to solve the problem. There were frequent connection breaks and the internet speed was very slow. At first, I was thinking about buying a new router, but at the same time under Windows 8 everything worked with a bang.
I have left Ukraine 6 years ago. Nowadays if recruiters ask me about relocation to Ukraine I’m alway refuse. In this post, I want to write about what’s wrong with Ukraine in my opinion.
Then they asked me to write more tech details about my previous jobs. Why I’m sharing all these answers? Because I have never written so many in English about myself before. And I want to use these unique texts to market myself. Also, in the end, I was rejected with a ridiculous reason and I will write about it later.
Once upon a time in the evening in one programmer chat, some programmers felt boring. And I don’t remember why, but we started to compare programming languages performance using the Fibonacci algorithm in its recursive implementation. Many times passed since it happened. Only artifacts such as source code left on my hard drive and that’s why I decided to create this post.
The task was to get from a positive integer encoded in the base -2 it’s negative equivalent in the same base. So, to solve this task we need to split it into two parts. In first one we will use a formula to get an integer from its code. And in the second part, we will encode this negative integer back to base -2.
I didn’t know how to name this problem, that’s why I named it as it’s written in the post title. This is a problem from another coding test on one of these coding challenge platforms. I still think that these platforms are just an automation of this weird “whiteboard coding” process. And it’s a pity that companies still believe that such tests could indicate really good programmers. Probably I would write a post with my thoughts on this topic later…
First time I faced this problem during one of my codility tests for a work application. And I failed it. :) Just because I have never heard about such problems before. Anyway, my opinion about codility tests is the same as about writing code on a whiteboard. A programmer should be able to think, to investigate and solve the problem in the end. You can’t train yourself for every existing problem and their endless variations. It’s true especially for whiteboard coding challenge because you have limited time and can’t use online resources. Stress not compliment process of thinking, it destroys this process. Well, it’s a topic for another post. In this post, I will provide my investigation on a Knight distance problem and a solution.
