The module was created as a part of my master thesis in the 2010 year. The master thesis theme is Keylogging in Linux kernel. The main idea was to find out a way to intercept system calls for x64 arch Linux kernel, especially for kernel 2.6.34.7-61.fc13.x86_64.

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.

Introduction & Recap

In the previous blog post, we started designing our application rendering a table with some Business Partner. We learned what OData protocol is, how to read an OData XML manifest, how to bind data to a Table and how to customize columns layout based on different screen resolution.

What will be covered on this exercise

With Part 2 of this series of blog posts, we will learn how to interact with data in our Tables and List. We will learn how to filter and sort data in a smart way.

• Create JSONModel to handle local data
• Set a default sizeLimit to our JSONModel
• FilterBar: UI control that displays filters in a user-friendly manner to populate values for a query
• Use XML Fragments to create a View Settings Dialog to handle sort and group data
• Filter and Sort data
• Add an Info Toolbar to our table to display useful information

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?

The problem statement

Introduction & Recap

In the previous blog post, we have created a new SAPUI5 application on our SAP SCP WebIDE Full stack and we have configured it to use the destination to the SAP Netweaver Gateway Demo ES5.

What will be covered on this exercise

• What is an XML Metadata Manifest and what’s inside it?
• How to use our OData Model and bind it into our application
• Use a sap.m.Table with items and property binding
• Use sap.ui.model.type.DateTime to format JavaScript Date
• How to style columns to act differently on mobile/tablet/desktop devices

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 lack of definition for intelligence and hence lack of measure for it [1a] [1b].

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

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].

Intelligence is more about applying/transferring old knowledge to new task (playing Quake Arena good enough without any training after mastering Doom) than it is about compressing experience into heuristics to predict outcome and determining action to maximize predicted outcome value in given state (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 algorithm to learn to play Go is more performant adaptation, and developing mathematical theory to play Go might be even more performant.
