The Uml digram

 

The blog
post, UML Diagrams – Everything You Need to Know to Improve Team Collaboration,
provides a clear explanation of Unified Modeling Language(UML) Diagram, its
usage and types ending with how it helps to visualize the project. Starting
off, the blog covers the usage of UML diagrams, continuing with its key uses,
forward design, modeling before coding to plan a system, and backward design, modeling
after coding to document a finished system. Also, it covers the thirteen UML diagram
types and what each type shows and describes what each type represents and how
it contributes to visualizing processes effectively.

I chose this
article as it summarizes clearly what the UML diagram, its usage, how the UML
diagram can be used to collaborate with other teammates. First was that since
the class, I felt that I needed to understand UML diagrams better as I still
did not get what use does it has. The fact that it emphasizes UML diagram as
white board for building and analyzing the system the team gave me some reason
for understanding more about UML diagram. Not only that, but the article also
clearly goes in-depth about the UML diagram that goes way in depth compared to
the course of behavioral and structural diagrams and how they can fit together
in real-world workflows. Overall, this blog clarified how UML diagrams support
collaboration as a visual tools to help team members to see and discuss system
structures and behaviors. It made me view UML not just as an academic
requirement but as a practical communication tool that can strengthen teamwork
in future software projects.

           After
looking at the article and learning more about UML diagram, I felt like even
though it might not be perfect, that I might have to use it for future use. When
coding I have something on my mind to create, but when trying to explain it or comment
on the structure of the code. Sometimes others don’t understand or sometimes I cannot
remember why I did that later. Not only that, but the rough draft of the
structure can also be used when talking with other teammates because I cannot
do everything by myself and we need to see the same picture, and I think UML diagram
will be the virtual whiteboard for it.

The Real Value of Open Source Software

Open source software is so valuable to society, but how would that value be translated into currency? About 96% of all commercial companies contain code that originates from an open source software (OSS). But according to new articles and papers being written on the subject the amount that these free softwares save these companies is a lot larger than people originally expected. Without it, firms would pay an estimated 3.5 times more to create the software and platforms that run their entire business which in total would be around $8.8 trillion in total. Due to this many companies make sure to express how important it is to hire people who have experience with open source software as it is the backbone of companies. The authors  of the article calculated the estimated value of open source software by combining data from The Census II of Free and Open Source Software and BuiltWith, which is a database that takes millions of websites and identifies technologies they use. To estimate the cost of recreating these open source projects from scratch, the researchers analyzed the number of lines of code in each project and used the COCOMO II cost estimation model, that predicts development effort and expense based on the size of the code and how complex the code is. They then adjusted these amounts using regional wage data to show how much it would cost in labor throughout the world. This allowed them to estimate that both the cost it would take to replace all of the software would be around $4.2 billion and the total value of open source software being used in the world is almost $8.8 trillion. The reason I used this specific article was because of our current discussions of open source software and how important it is to not only people who are in tech, but also people who are less fortunate and need the resources that this free software gives them. So to see an article that explains what the commercial value this software provides around the world and how much it is actually worth is shocking and goes along perfectly with the importance we saw of it in class. The article itself was very interesting to read about as well. To think about how much it would actually cost to create this software is absurd and really opens my eyes as to how large it actually is. Before reading I believed that it was helpful, but I didn’t know the importance it has in actual companies. As well as how helpful it is to have experience in open source software when it comes to jobs as well. I am definitely going to do more research into different software and hopefully it helps me with my future career.

Beginners guide to Software Licensing

by Petraq Mele

Hello to all reading this blog today, the topic this time is software licensing and its importance in the development of software. I began researching about it as I had very limited knowledge about it and its importance. I ended up reading a blog written by an experienced developer named Rahul Awati titled “What is a software license?”, and I ended up learning quite a lot about the importance of this topic.

Various icons representing software licensing concepts and principles.

So what exactly is Software Licensing?

Practically speaking software licensing is a document that provides legally binding guidelines for the use and distribution of software. You can think of all software licenses as essentially a contract between the developer(s) and its user(s). It outlines the rights between these two parties for a piece of software along with the terms and conditions. All software comes with a license/product key which is important for identity & verification.

Its fairly simple to license software. Legally you already have, as the author of your software, a natural right recognized by copyright laws. If you want to add anything else to a license many developers but it in a text file within their software packages. Some sources like choosealicense.com or www.gnu.org are useful for finding templates or examples.

Some things that you may find included in a license are:
– Basic information(Names, Contacts, Address)
– Charges
– Duration
– Distribution rules
– Terms of service/cancellation
– Governing law
– Maintenance
– Etc.

Types of software licenses:

A visual representation of the 5 approaches to software licensing, ranging from public domain to proprietary licenses.

A few software licenses include:
– Free and open source(FOSS): Allow anyone to use software, and even to study, change or copy its source code.
– Proprietary: Often referred to as “closed source”, this software has strict rules towards obtainability & alterations.
– Public domain: Like open source but should be cautiously used by businesses as it might not meet their expectations.
– Lesser general public: Developers can link to open source libraries within their software and use any licensing type for the code.
– Permissive: Allows users to modify & distribute a piece of open source software but with some requirements for them as well as preservation of license notices, copyrights, or trademarks.
– Copyleft: Open source as long as they make the modifications freely available. New products containing old code with a copyleft license must comply with the restrictions laid out in the old code’s license.

Why do we need licenses?

Licenses are important because of all the reasons we have outlined earlier. It helps protect both the developer & the user.

A few beneficial protections for developers include: Protection of intellectual property, ensuring control over their creation, limiting liability, & monetization of products.

As for the users, the benefits are: Prevents misuse/unintentional mistakes causing damage, protect from infringement claims/ liability, create positive relationship with other developers/users/vendors, & establish clear parameters of how many licenses an organization needs.

Based on these few protections you can see the importance of licensing. It keeps a professional structure towards the spread of software and encourages a just environment.

Final thoughts

Understanding software licensing is something each software developer should take the time to learn whether for their own personal gains, or as a way to safely use/produce software. Aside from the legal aspect of it, licensing is about respecting a developer and their work. As I mentioned earlier I want to give credit to Rahuls’ amazing blog as inspiration for mine. Be sure to read his blog if you want more insight on this topic.
