## AngularJS: Tutorial: Part 1

Background

AngularJS is an open source framework, designed for the creation of enhanced web applications, created by Miško Hevery at Brat Tech LLC, and maintained by Google plus a community of developers and corporations. It implements most of the concepts behind all new standards on web components and model driven views. This framework is in the category of data binding frameworks.

## Living in the “Industial Era” in the 21st Century

Today, I am planning to begin my route into AngularJS. Currently, I am searching for a job and due the fact that I do not know AngularJS have closed to me many great opportunities. It did not matter if I am a nice guy, if I am a fast learned, or if I was in charged of developing and maintaining critical systems that cost and/or generated thousands of dollars at my previous jobs. My lack of knowing a framework such as AngularJS have being the major reason for being rejected. At least, that is the reason I was told.

We still behaving like in the “Industrial Era”, even do we are leaving the “Information Era” and getting into the era of “What to do With so Much Information Era”. In this new era, you are required to learn, re-learn and even forget faster than never before. The technology you are using today, can be easily replaced by something else, quite fast. Programming languages, libraries, and frameworks can be learned thanks for the available tools such as Internet, books, and so for. How to do clean, reusable, and expandable code is different matter. That takes time, experimentation, practice, and experience.

## Maximum Flow

Definition

• The capacity constrain indicate that a given capacity must not be exceed by the flow from one vertex to another.
• The skew symmetry (a notational convenience) indicate that the flow from vertex $u$ to vertex $v$ is the negative of the flow in the reverse direction.
• The flow-conservation property indicate that the total flow out of a vertex other than the source $S$ or sink $t$ is 0
• The total positive flow leaving a vertex is defined symmetrically
• The total positive flow leaving the vertex minus the total positive flow entering a vertex is the  total net-flow at a vertex
• The total positive flow entering a vertex other than the source $S$ or sink $t$ must be equal to the positive flow leaving that vertex.

Examples

## JavaScript: Safari: iOS8+: Touch Events and WebAudio: Issues

09.25.2015, No Comments, JavaScript, by .

Be aware, under Safari (iOS8, iOS9) there are issues related with touch events and audio when using JavaScript.
People are reporting that they encounter issues with touchStart, touchEnd and all existing content using WebAudio.

Sometimes changing the binding from touchStart to touchEnd solves it.

## DNX: C#: Lambda

09.01.2015, No Comments, .NET, C#, DNX, by .

As you may know, Microsoft is getting into the open source community with the ASP.NET and DNX with the mono project.
The .NET Execution Environment (DNX) is a software development kit which allows you to run .NET applications on Windows, Mac, and Linux using different frameworks such as .NET framework, .NET Core, and Mono. However, everything are not roses. There are many incomplete libraries, incompatibilities, lack of documentation, and most of the examples such as doing SQL or SOAP do not work depending on which the library targets you are planning to code for. Therefore, I decided to test the basics on all the library targets. I am starting with DNX451.

Lambda seems to be working fine in DNX451 with C#. Below is a code example for those who wish to play with it.
