Introducing UMLet: excellent free UML tool

Just as the saying stands: "Reduce everything to its essence so that form harmonizes with function", graphical diagramming notations have considerably helped for better communication and understanding in Software Development.

A diagram can help us better express our ideas about Software Design without putting textual explanations. It's already confirmed that human brain better processes images than texts. That's why graphical representation through diagrams is quite effective to communicate and express our ideas either for a Software System or a Business Process.

Boolean Algebra - Digital Logic

Digital Logic
Motherboard
Boolean Algebra plays a crucial role on every aspect of Computer Science. In programming we know it as true or false statements whereas in digital logic we have 1 and 0. We can use these statements to determine different types of behavior whether in programming or in electronic circuit design. We will see how we can transform entire mathematical formula and design a circuit with the help of boolean algebra.

In these modern days of technology, smart electronic chips have capacities to choose different types of behavior and even playing intelligent based on events that behave upon them. To do so chips use boolean algebra to compare or do branching depending on the logic that has been designed for them.

Binary Numbers - Addition


Binary Numbers
Binary Numbers
Arithmetic operations with binary numbers can be useful especially if you want to learn machine language, or you are programming an electronic chip or maybe a central processing unit CPU.

We can do arithmetic operations with binary numbers just like we do with decimals. Simple enough, arithmetic operations can be very straightforward we just need to follow some rules and concentration. Since we work only with two digits 0 and 1 some operations can be challenging, however a bit of concentration will allow your logic to clear its path. So lets see how electronic machines actually do math on their way.

Which programming language should i learn ? - Answer yourself !

Programming Languages
Programming Languages
Choosing a programming language can be difficult. It all depends on your needs. But the overall logic is always the same. When programming you are solving problems. When choosing a programming language you are not choosing simplicity, rather you are changing the syntax of commands you write.


So do not be trolled by the idea that there is a language that is easier and can do complex tasks. Remember a programming language is not a software. It all depends on what you are going to program. Even assembly can be easy if you use it just to multiply two numbers.

Binary numbers - Digital Logic explained


If you ever asked yourselves how computers think and logic then what you are asking is Digital Logic. There is an order and logic on how computers do all that stuff for us. If you are a computer science student then you know that in the very end computers only understand binary. 

You may write a very sophisticated software in any high level programming language, but in the very end everything is converted to machine language or binary. But why exactly binary ? What in reality is binary ? It's because electronic chips are made like that. They can only understand two states of behavior. TRUE/FALSE, ON/OFF, ACTIVE INACTIVE, SET/RESET. 

Whatever the situation these are called zeros and ones : 0101010001010101. Whenever there is 1 that means there is some input or value or something is happening, and whenever there is 0 that means its null or nothing. By combining different values of zeros and ones we can achieve interesting statements and chips can behave in a manner that we can command them to do some stuff for us. These zeros and ones are inserted in a digital circuit where they travel, and depending on the design of this circuit these numbers can flow in a way that they do something logical. 


These circuits are inside every electronic chip. Different chips have different circuit designs and a very large amount of zeros and ones travel inside these chips. The CPU has millions of millions of circuits that do different tasks. Billion of data travel inside these circuits. These circuits are designed in a way that they can do some logical operations. 

However we cannot understand digital circuits if we don't know what will live inside them. That is Binary. We must firstly get to know those zeros and ones. In the section below we describe everything about binary. We will learn how to understand binary numbers, convert them and do arithmetic operations just like we do with normal decimal numbers we use in our everyday life.

Binary Numbers

If we think, the numbers we use in everyday life are called decimals. Why like that ? Because they are formed of digits starting from 0 to 9. If we count from 0 to 9 we get 10 digits. Which means the decimals. On the other hand binary numbers consist of two digits, that is : 0 and 1. Every digital machine works on binary numbers. Binary numbers can be used to do operations just like decimals. We just need to follow some rules. For simplicity we will start converting decimals to binary numbers and vice-versa. Then we will do arithmetic operations with binary numbers just like we do with decimals.

The table below shows the corresponding binary combinations for decimal numbers from 0 to 9.

Decimal                  Binary

0                            0000
1                            0001
2                            0010
3                            0011
4                            0100 

5                            0101
6                            0110
7                            0111
8                            1000
9                            1001


We can prove this combination by converting any decimal number to binary or any binary number to decimal. When converting decimals to binary and vice-versa there is a rule we need to follow. For example let us take number 79 and convert to binary.

Decimals to binary

a ) Convert number 79 to binary

To convert any decimal number to binary we need to divide that number with the base of the numeral system we are converting to, in  this case binary which is 2. The base of binary is 2 because this numeral system consist of two digits. The base of decimal is 10 because this numeral system consist of 10 digits. When dividing if we get real number ( number with dot ) we simply avoid numbers after the dot and write only the integer. If the dividend is even the binary remainder will be 0 and if the dividend is odd the remainder is 1.

79 : 2 = 39.5 = 39 remains 1
39 : 2 = 19.5 = 19 remains 1
19 : 2 = 9.5 = 9 remains 1
9 : 2 = 4.5 = 4 remains 1
4 : 2 = 2 remains 0
2 : 2 = 1 remains 0
1 : 2 = 0.5 = 0 remains 1


The division goes till we reach 0. After we finish we write binary numbers in a counter way, like for this example the binary combination of number 79 is 1001111.

b ) Convert number 355 to binary

355 : 2 = 177.5 = 177           remains 1
177 : 2 = 88.5 = 88              remains 1
88 : 2   = 44                       remains 0
44 : 2   = 22                       remains 0
22 : 2   = 11                       remains 0
11 : 2   = 5.5 = 5                 remains 1
5 : 2     = 2.5 = 2                 remains 1
2 : 2     = 1                         remains 0
1 : 2     = 0.5  = 0                remains 1

The corresponding binary combination for decimal number 355 is 101100011.

c ) Convert number 4394 to binary

4394 : 2 = 2197                   remains 0
2197 : 2 = 1098.5 = 1098      remains 1
1098 : 2 = 549                    remains 0
594 : 2 = 274.5 = 274           remains 1
274 : 2 = 137                      remains 0
137 : 2 = 68.5 = 68              remains 1
68 : 2 = 34                         remains 0
34 : 2 = 17                         remains 0
17 : 2 = 8.5 = 8                   remains 1
8 : 2 = 4                            remains 0
4 : 2 = 2                            remains 0
2 : 2 = 1                            remains 0
1 : 2 = 0.5 = 0                    remains 1

The corresponding binary combination for decimal number 4394 is 1000100101010.

Binary to Decimal


To convert binary numbers to decimals we count the digits and power the base 2 with the counter. Then we do addition with the binary digit and result. We continue this for every binary digit and then we multiply the results. The end result is the corresponding decimal number to the binary number we are converting for. Take this formula for example.









The corresponding decimal number for binary 11011 is the number 27. Let us break in detail. As we said we mark the binary digits with counter. Then we power the base 2 with the actual counter. For this example that would be

1 x ( 2 x 2 x 2 x 2 ) = 16 = 1 x 16 = 16
1 x ( 2 x 2 x 2) = 8 = 1 x 8 = 8
0 x ( 2 x 2 ) = 4 = 0 x 4 = 0
1 x 2 = 2
1 x 1
= 16 + 8 + 0 + 2 + 1 = 27


Notice in the end if we power any number with 0 we get 1 that is why we wrote 1 x 1. When multiplying the results we get the final corresponding decimal number for the binary number we are converting for in this case number 11011 to decimal is 27.

Summary

There are different ways to convert numbers from decimal to binary and binary to decimal. We expect from you to explore. Binary numbers can be interesting especially if we know how to apply those values to Digital Circuits. In the next blog post we will explore arithmetical operations with binary numbers, just like we do with decimals. After that we will explore digital circuits, how to draw them and how binary numbers act upon these digital circuits. With that explored, we will have an overall understanding of electronic chips and inner workings of computers brain.

Linking C# Applications with MySQL Databases on Visual Studio

c#-mysql
Visual Studio as we know is a very powerful IDE from Microsoft. It has build in languages like C# C++ and Visual Basic. Development with Visual Studio can be pretty fun and successful. Visual Studio also has methods for creating and connecting to Databases like ADO.NET technology.

However for some personal reason you dont want to use ADO.NET technology for your Databases or SQLServer for the simple reason that they are expensive. Perhaps you want your applications data to live forever, and never be gone if your hard drive burns or dies.

Case Sample: Cinema Application ER Diagrams

Cinema ER Diagrams
Cinema ER Diagrams
Product or Service design is one of the most important steps on engineering. It's the step where you graphically create the specifications, features, goals and the main notes of the product/service requirements. In Software Development we have Software Design which is the activity after the setting of requirements and before programming implementation.

As we already know, the human brain captures better the pictures than words. Defining system features, concepts and complexes through some sort of standardized diagramming tools is far more better than describing it with words.In this case sample we will try to build ER Diagrams for Cinema Application. As previously explained  the design step is primary during the Software Development Process, in turn the step of Database Design is one of primary importance for the logical construction of Databases.

The process of Innovation

Innovation
Innovation
I suppose everyone asks questions as what are the innovation drivers? Well, observing the world and it's complex events we can firmly deduce that one of key innovation drivers are the market pull, technology push, and society demand.

 To this point it's clear that depending on the market demand we concentrate on creating or bringing something new and innovative to that market, innovation also depends on the demands or needs of the society as well as the push from technology. The basis for Innovation would stand the Creativity. But, how can we define creativity? Well, it's already defined and we will only quote it.

PS4 - The new gaming console - Sony hides many things we should know.

PlayStation 4
Earlier this week we finally got a look at the next generation of console gaming (sorry, Wii U). Though Sony announced some amazing features for the PlayStation 4, the announcement left some of us a little underwhelmed  - most likely because of what we still don’t know about the console.

A number of features and specs were announced, most notably the x86 architecture and the admittedly impressive “backseat gaming” streaming functionality. However, even though Sony’s new console will allow us to play a friend’s game (that we don’t own!) over the internet, the event was underwhelming for a handful of reasons.

Business Processes and Innovative Technologies deployment

Business Processes
We have already defined business processes but we will repeat in a different manner the definition of it and also explain the role of IT in implementing the business processes of an organization.








A business process:
  • Is triggered by an external event.
  • Is composed by different activities or procedures which are necessary to provide a business outcome in response to the triggering business event.
  • Transform inputs into outputs.
  • Contain activities which are usually cross functional and operate at different operational units.
  • Delivers a product to a outside stakeholder or another internal process.
  • Usually connects to other internal processes.
  • It's how we do what we do.

Information Systems and Organizations

Information Systems
First of all, let us define what is an Organization. An Organization can be defined as a formal structure which takes resources from the environment processes them and makes output.

 One organization can be divided into some functional areas like: Production and Manufacturing, Sales and Marketing, Finance and Accounting and Human Resources Department. All of these functional areas have their own task levels such as: Operational level where major business events or transactions are recorded, Middle Management level where they put in work the plannings of the Upper Managements who in turn are responsible for the long term strategies and planning of the organizations.

Digital Library: Data Design with UML, identifying couple of business processes

Digital Library
Analyzing the data and designing core and supporting processes for a certain problem is very crucial in Software Development. In fact the requirements and the analysis of the data is the first step to do in the development of a software.

To demonstrate Data Design and identification of core processes  i have taken the Digital Library as case example. The Data Design has been made with UML (Unified Modelling Language) specifically with the Activity Diagrams which task is the identification of the activities of a certain problem, and to lesser degree Component Diagrams to hide several details for syb-systems like Databases and Sales Improvement which in turn provide and accept functions.

Innovation: Definition and Trends

Innovation
Let us make a definition. What is Innovation?

According to Schumpenter: Innovation is the process and outcome of creating something new, which is also of value. It involves the whole process from opportunity identification, ideation or invention to development, prototyping, production marketing and sales, while entrepreneurship only needs to involve commercialization (Schumpeter).

Or by other definition: Innovation is the introduction of new ideas, goods, services, and practices which are intended to be useful (though a number of unsuccessful innovations can be found throughout history). There is five types of Innovations.

OpenGL Backface Culling - Removing unseen faces to improve performance

OpenGL
OpenGL can be very useful if we know how to use it. But sometimes it can tire up our computer and eat performance resulting to slow application. No one likes this especially gamers. They want smooth games and  experience with 90 FPS during their gameplay. It is useful to know some pitfalls we should prevent when creating OpenGL applications.

There are many factors that reduce performance of your application, it depends on the code for example dynamically memory allocation and not freeing those resources, loading and displaying complex 3D meshes and scenes, calculating complex lighting algorithms etc. In this post i will discuss a very useful technique that OpenGL offers us to drastically improve performance of our applications. That is backface culling. Backface culling is a technique that slices up faces that are never seen.

OpenGL as we know is a low level API for manipulating computer graphics. It is very powerful and cross platform which means all operating systems support it. This is the main reason i want to develop apps with opengl. I dont want to stick with Windows only, rather as a lover of Ubuntu i like to create small programs for this platform also.

OpenGL is powerful but when it comes to create big 3D worlds and meshes it can be very very hard nearly impossible to do this all by code. So you cant just create small games with OpenGL only. You need to create your 3D assets on other 3D modelling software and to export them and after that to create functions or classes in C++ that will read those exported files and parse them into your final program. In the code below you have a class that loads OBJ files and displays them onto the screen. OBJ is powerful file format and is very easy to implement parser for those files.

Ubuntu for Mobiles is described as fast OS with basic code and no Java overhead. It uses the same drivers as Android so customers can have better experience.

Moreover, they have published their new SDK which makes it easier for developers to code in HTML5. So, they have their Web App System which let us adapt any web as an app on the phone which in turn runs separately from the browser.

Installing SDL libraries and creating your first window on Ubuntu

SDL libraries
SDL is used for creating graphical user interfaces or small games. But if its used correctly you can also create robust graphics applications or games. Simple Direct Media Layer is used to manipulate pixels to create different ui layouts for your applications and even games.

In my other blog posts i discussed about downloading installing and configuring SDL under Windows with Visual Studio. Here we will explain how to get running this library under Ubuntu. Graphics programming under Ubuntu are becoming more popular like even EA started to create games for this platform.


Compiling and running C++ source codes in Ubuntu

Compiling and running C++
With its clear fonts and pixel percet ui Ubuntu makes it so comfortable for me to code in many programming languages. With a lot of free tools and support Ubuntu is an amazing work desk for every developer. Coding in C++ under Ubuntu is all about using the terminal. Thats it.

You just install Geany text editor if you dont like the default one and with some packages you will be all set up. So lets get started. As we said the first thing you will do is open the Terminal. Firstly we must make sure that we have all the necessary packages to start writing codes. Type this command in terminal

Ubuntu installation - Dont play with swap space ! It can cost you data loss !

Ubuntu installation
This article is not going to explain the ubuntu installation as its very easy and it can be done with some 4 or 5 steps. But if you dont pay attention to what you are doing you can very easily loose your data and become an old man in just 5 seconds.

Thats it i couldnt believe what i did with just one click. I deleted 248GB of data on my hard drive. Just because i wasn't careful enough and of course lazy to backup my data before i do anything else. The ubuntu installation provides you with the 3 main options. To install ubuntu alongside an existing operating system, to delete everything else and to make clear ubuntu installation and the last one which gives you more control to make partitions and separate ubuntu installation on different area.
