There are only two hard things in Computer Science: cache invalidation
and naming things.

— Phil Karlton

We, developers, spend more time reading code than writing it. It is important for the code to be readable and clear about its intent.

Below are some advice based on my experience naming things.

It is text version of the presentation 2018-04-25 at Saint-Petersburg Linux User Group. Configuration example locates at https://github.com/ultral/ansible-role-testing

I suppose that that you make configuration management, not bash. It means that you have to test it some how. Have you ever tested ansible roles? How do you do it?

Let's imagine that you are developing software and hardware appliance. The appliance consists of custom OS distributive, upscale servers, a lot of business logic, as a result, it has to use real hardware. If you release broken appliance, your users will not be happy. How to do stable releases?

I'd like to share my story how we dealt with it.

We have a problem. The problem with testing. The problem with testing React components, and it is quite fundamental. It’s about the difference between unit testing and integration testing. It’s about the difference between what we call unit testing and what we call integration testing, the size and the scope.

It's not about testing itself, but about Component Architecture. About the difference between testing components, standalone libraries, and final applications.

Everyone knows how to test simple components(they are simple), probably know how to test Applications(E2E). How to test Finite and Infinite things…

1. Introduction

Yesterday I’ve blogged about the content I’m creating for new developers that have arrived at our Techedge office in Lucca.

Teaching is something I started to love, is the natural consequence of the fact that I love to learn and love to share my knowledge. And I think that it’s important that new students or young developers have some curated content to start with, maybe with also some tip&tricks that senior has learned during their journey.

The idea behind this exercise is to cover every topic a SAPUI5 developer should know and understand.

The exercise will be available on my GitHub project openui5-exercise.

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!

The biggest issue with AI is not that it is stupid but a lack of definition for intelligence and hence a lack of formal measure for it [1a] [1b].

Turing test is not a good measure because gorilla Koko [2a] and bonobo Kanzi [2b] wouldn't pass though they could solve more problems than many disabled human beings.

It is quite possible that people in the future might wonder why people back in 2019 thought that an agent trained to play a fixed game in a simulated environment such as Go had any intelligence [3a] [3b] [3c] [3d] [3e] [3f] [3g] [3h].

Intelligence is more about applying/transferring old knowledge to new tasks (playing Quake Arena good enough without any training after mastering Doom) than compressing agent's experience into heuristics to predict a game score and determining agent's action in a given game state to maximize final score (playing Quake Arena good enough after million games after mastering Doom) [4].

Human intelligence is about ability to adapt to the physical/social world, and playing Go is a particular adaptation performed by human intelligence, and developing an algorithm to learn to play Go is a more performant one, and developing a mathematical theory of Go might be even more performant.

Introduction

At the start of September 2018, some cool guys also joined our team, they are fresh from University and they are really hungry to learn how to design and develop amazing web apps with SAPUI5.

That’s why I’ve started to collects internally on the web some links in order to create “The perfect journey to become a SAPUI5 Ninja Developer”.

I’ve also started to write down some exercise (from easy to hard) in order to test what they’ve learned but I will share those in a second blog post as soon I’ve finished them.

Presentation

Hi everyone,
I'm Emanuele Ricci, a full-stack developer based in Lucca (a beautiful little city in Tuscany, Italy).

Since the last three years, I work full-time for Techedge Group, a big worldwide consultant company that is a partner with SAP. I usually work in projects related with SAPUI5, SCP, HANA and in my free time, I love to create content around the technology I use at work and in my personal projects outside SAP. Lately, I'm a little bit experimenting with Android after the release of SAP Fiori SDK for Android/iOS.

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.

Configure the development environment for learning HTML, CSS, PHP in Windows.

Beginning programmers always ask the question, where to start learning about creating websites? Search on the Internet gives a lot of various information, but unfortunately only more confuses novice developers. Having more than 5 years of teaching experience, I have seen many times how students, making breaks in computer games and deciding to become web developers, tried to customize development environments. They began to sort out the programs for layout. They grabbed Sublime Text, Notepad ++, Visual Studio Code, NetBeans or PHPStorm. We tried to install on our local computer WAMP (stands for Windows, Apache, MySQL and PHP) platforms, such as Denver, Xampp, Open Server and many others. But since there is no systematic knowledge in the head of a novice developer, there is no experience of customization, it was rare for some of them to set up a convenient development environment, and whoever got it, understood that it became more difficult to play, since many additional programs, smoothness in the game.

This article was born because of explaining for many years to each student how to do everything correctly and conveniently.

Once again I want to say that we will set up a working environment in the Windows system to study the creation of sites in HTML, CSS and their links to PHP. We will call this computer working, so that beginning web developers get used to the idea that their computer is their source of income.

It's a story on how to write a plugin for Unity Asset Store, take a crack at solving the well-known isometric problems in games, and make a little coffee money from that, and also to understand how expandable Unity editor is. Pictures, code, graphs and thoughts inside.
