Programming Languages

-

This is my first time building a program using Scratch.  I was familiar with it prior to this post.  My main difficulties were selecting which blocks I wanted to use and the appropriate sequence for using them.  I also experienced a short learning curve with the main application interface.  Overall, the application is intuitive and a great starting point to learn the basics of programming for beginners.  I overcame my difficulties by watching a couple of the video tutorials and through trial and error.  

The insights that I gained about programming from this exercise was the importance of sequencing and understanding what each block does and when they can be utilized. I understand the concept of machine language translating 0’s and 1’s.

My Scratch Assignment

 

The differences in programming languages is the code they use, interpret, as well as their capabilities and purpose. For example, web browsers use HTML, HTML5, CSS, JavaScript, and other programming languages to build web pages and a web browser like Firefox or Chrome interprets that code and outputs it for the user.  The same is true of C, C++, Python and Java.  They are used to create software or parts of software. Many Windows programs are built using Visual C++. Of the languages listed in the book in section 2.10 I found JavaScript the easiest to use primarily because I am somewhat familiar with it.

These are scenarios where common types of programming language would be most effective:

·         C: Is the basic building blocks of C++, Java, and JavaScript.  UNIX initially coded using C.

·         C++: Used for a variety of programs, including Windows applications and video games

·         Java: Object-oriented programming language for building client–server web applications

·         Python: Modular object-oriented programming language focused on syntax simplicity has made it a popular choice among programmers

·         JavaScript: Scripting language that adds dynamic capabilities to web pages such as redirecting a user to another page, generating a pop-up ad, or web form validation.

I think C++ and Python are the most popular programming languages in the list because many Windows applications are built on C++ and Python has gained momentum for its ability to learn, and extensibility.  Many companies are actively hiring programmers who know Python which is a testament to its flexibility.

Network Security

-
  Information and system security is essential for individuals and organizations using internet-connected computer systems because these computers are easily susceptible to a variety of security attacks. A security breach is “a case of unauthorized computer access”. These breaches come in a variety of forms including being attacked by a computer virus, having web server’s shutdown, being locked out of a compromised system, being hacked and having secret programs like keyloggers installed that track every key you press on your keyboard, having sensitive information like suggestive photos, credit card or contact information stolen and even possibly leaked. An example attack is a denial-of-service attack (DDoS attack), such as Ping Flood Attack or the Ping of Death attack. DDoS attacks overwhelm the computer system “with too many requests for resources, such that it cannot respond to legitimate requests. ( The University of Texas at El Paso, n.d. ).” Security software can protect ind...

Mobile App Critique - Piwigo (Open Source Photo Management Software)

-
Image
The app I am reviewing is Piwigo , which is open-source photo management software.  I realized I have taken hundreds of thousands of photos over the years.  These photos are sitting on my hard drive, and I am the only one who has access to them which isn’t doing anyone else any good- especially friends and family members who have been photographed. I maintain our family web site and had been seeking a way to integrate all the photos, that was password protected, allowed photos to be tagged so we could easily search for people or places, and had permissions so my immediate family could see everything, yet my father and stepmother only saw relevant photos, and my mother and stepfather and related siblings also only were able to see relevant photos. In addition to integrating into my web site, I wanted app functionality that would allow me to immediately upload photos from my smartphone.  I found all of this and more (for free) in Piwigo. Usability, Design and ...
