Abnormal programming *

The AI Cup community and Mail.ru Group in collaboration with Codeforces.com invite you to the real battle! Get ready for the sleepless nights and calloused hands — take part in Russian AI Cup, which is one of the most challenging and vivid artificial intelligence programming competitions in the world. Believe us, managers of this madness did their best to create the game you'd want to play.

To become part of the competition, you need Internet access, computer, creativity, and enthusiasm for being a part of this extraordinary Cup. By the way, you might need some coffee. Welcome!

A few days ago 0xd34df00d has published the translation of the article, describing the possible information about some function if we use it as a "black box", not trying to read its implementation. Of course, this information is quite different from language to language; in the original article, four cases were considered:

• Python — dynamic typing, almost no information from signature, some hints are gained by the tests;
• C — weak static typing, a little more information;
• Haskell — strong static typing, with pure functions by default, a lot more information;
• Idris — dependent typing, compiler can prove the function correctness.

"Here's C and there's Haskell, and what about Rust?" — this was the first question in the following discussion. The reply is here.

Happy programmer's day! I wish you more bright commits, merged pull requests, less merge conflicts, and that your life branches remain relevant as long as possible. As a conceptual gift, I propose the implementation of a family tree by means of the Git version control system. Well… sounds like a plan!

For those who have immediately understood everything, I give links to the source code: GenealogyTreeInGit and family trees: mine and US presidents.

In addition, I implemented a simple social graph. It displays not only the degree of kinship, but also the status of relations between descendants, events such as wedding, divorce, childbirth, as well as contributions to the relations.

Hi, my name is Michael Kapelko. I have been developing software professionally for more than 10 years. I develop games and game development tools in my spare time.

This article describes my first durable application for desktop PCs: PSKOV static site generator.

Durability

A durable application is an application that functions without a single change on operating systems released in years 2010-2030. In other words, a durable application has backward compatibility of 10 years and has the stability to run for 10 years. Actually, PSKOV runs even under Windows 2000, so PSKOV has backward compatibility of 19 years.

In this post we'd like to share an interesting way of dealing with configuration of a distributed system.
The configuration is represented directly in Scala language in a type safe manner. An example implementation is described in details. Various aspects of the proposal are discussed, including influence on the overall development process.

Have you ever thought — How to explain programming to the one never faced it before? It could be a problem, as long a new one will not understand you.

So, let's imagine — you have a friend, who is not soiled by computer science, never tried to automate something, never played factorio, never written a single line of code.

So, let's imagine a normal human being.

And let's call him Bill. He is not very good in Maths, just “not good”, but he loves candies!

Your task is to teach Bill some basic(or magic) IT things, you are doing every day. The simplest ones.
So what shall you do first? Basically — FEED HIM!

In this article I'm going to tell you about one of the currying options and partial application of the functions in C++ which is my personal favourite. I'm also going to show my own pilot implementation of this thing and explain the point of currying without complex mathematical formula, making it really simple for you. We'll also see what's under the hood of kari.hpp library which we'll be using for currying functions. Anyway, there are lots of fascinating stuff inside, so welcome!

StarCraft: Brood War. This game means so much to me! And to many of you, I guess. So much, that I wonder if I should even give a link to its page on Wikipedia or not.

Once Halt sent me PM and offered to learn Rust. Like any ordinary people, we decided to start with hello world writing a dynamic library for Windows that could be loaded into StarCraft's address space and manage units.

The following article will describe the process of finding solutions and using technologies and techniques that will allow you to learn new things about Rust and its ecosystem. You may also be inspired to implement a bot using your favorite language, whether it be C, C++, Ruby, Python, etc.
