## Greedy Algorithms Part 3 of 3 – Bubble Sort

This is the last part of greedy sorting series and after writing about selection sort and insertion sort before I want to close out the series with the exploration of an algorithm called bubble sort. Back in my CS class I remember my professor dedicated a whole slide to summerize bubble sort by putting: “Bubble SortLearn More

## Augmented Reality’s emerging use cases – metaio at work

I just finished an iPad application that is taking huge advantage of a technology called Augmented Reality. Augmented Reality (AR) is something not very known in our non-tech society today but as of late use cases are emerging. In case you don’t know about augmented reality here’s a quick roundup: To augment the reality means toLearn More

## Greedy Algorithms Part 2 of 3 – Selection Sort

This is part II of the three part series covering greedy sorting algorithms. After exploring Insertion Sort in the first part I now want to direct your attention to a sorting algorithm known as Selection Sort. It’s probably the most useless algorithm of the the main three greedy algorithms. Why is useless? Well, it’s best,Learn More

## Greedy Algorithms Part 1 of 3 – Insertion Sort

In this post I want to take a deeper look on the topic of sorting in computer science - especially greedy algorithms like in this case insertion sort. Sorting is a very common problem when computing data. As stated in an earlier article runtime analysis is an essential aspect of evaluating algorithms. So sorting consists ofLearn More

## What an algorithm is

In this post I want to dive in to the basic understanding of algorithms in computer science. They essential question in this context is “What is an algorithm?” The very famous book about algorithms “Introduction into Algorithms” (Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, Clifford Stein) defines: “(…) an algorithm is any well-definedLearn More

## Format Specifier in C’s printf()

Just recently I started going to back to some basic C lessons in order to enhance my programming skills on a very basic level. Therefore I now want to tell you about the format specifiers you can use for printing out the values of variables within an array of characters formed to a string. FirstLearn More

## UIView rotate forever

Nichts wirklich spektakuläres aber eine nette Objective-C Category zum Rotieren eines UIView Objekt mit verschiedenen Optionen. Wir haben das Original aus github geforkt und um eine Methode erweitert, die die Drehung theoretisch unendlich lange dauern lässt: https://github.com/Broich/UIView-i7Rotate360Learn More

## Core Data Migration Example (lightweight migration)

Recently I changed the managed object model in the Core Data stack in one of my apps and didn’t know I set a perfect cases for an Core Data Migration Example. No, not while the App was still under development where you can easily adopt new models by just reinstalling the application. You want toLearn More

## Why do things twice (3rd party libraries in iOS)

Anybody developing iPhone Apps probably using 3rd party libraries. Time is limited and why go for something, that was already completed by others in a perfect way and credit them for their hard work. Me personally I tend to take a good look around before I go and try to recreate something which is alreadyLearn More
