Web Technologies e.g. SASS, LESS and Doctrine

-
Web technologies, as the name indicates are the technology used over the world wide web. These technologies help the users to communicate with each other. You may have learned in your social sciences subject that Language is the main source of communication. Similarly when computers communicate, they also use certain specific language or languages for this. 
As we all know HTML is the hypertext markup language. It is the core of web technologies. Then comes JavaScript, React, Angular, Ruby, CSS and so on. 
Everyone likes beauty. CSS adds beauty to your page. But you need to write a lot of code for minute things in the style sheet. So to make the task of web developers convenient, Henry Thorton  with Natalie Weizenbaum designed and developed SASS (Syntactically Awesome Style Sheets) respectively. SASS is the style sheet language written in PHP. It is an extension to CSS and .css file can be converted to .sccs file. SASS is backward compatible meaning, it is compatible with all the versions of CSS.
LESS ( Learner Style Sheets ) is also one of the CSS preprocessors. It is based on JavaScript. LESS is dynamic CSS preprocessor, it provides the the run time compilation. Wikipedia says real time compilation of CSS.
We can have functions, variables and nested style structures both in LESS and SASS. The full guide to the installation and usage of SASS and LESS could be found here.
We have gone through the concept of Libraries in the previous blog post. Web technologies includes several languages, and almost each language has come up with several libraries. PHP is also one of those languages. And Doctrine is a project that is the hub of different PHP libraries. Doctrine itself says:
The Doctrine Project is the home to several PHP libraries primarily focused on database storage and object mapping.
And this database storage and Object mapping is done mainly using ORM (Object Relation Mapping : We'll get to this in coming blog posts)
So this was the brief overview of web technologies.
Technology is growing with each passing second or I would say; with each passing minute. And to sync our knowledge+morality with the technology is a challenging task.

1-Machine Learning : Start...

John went to the cafeteria 10 times at 1:00 P.M. on 10 Fridays, each time the cafeteria was closed at that particular time. John decided not to go to cafe at 1:00 P.M. on Friday because the cafe will be closed.  But wait! How did John know that the cafe will  also be closed on next Friday at 1:00 P.M.??? Yes, you are absolutely right.  "John Learned from his Experience that the Task of going to the cafeteria at 1:00 P.M. on Fridays resulted in waste of time, since the cafe was closed on each Friday, so it will Perform the same on the next Friday." In the above scenario, John learned something so we can call it " John Learning ". Similarly, if we replace John with some sort of Machine, that can learn from the Experience or from the History about how the tasks were performed in the past given certain situation. Such that the Machine will perform the same if the same task happen again in near future. Then this will be called as Machine Learning. To mak

   Data is a new oil. To channelize this data we need proper pipelines. These pipelines are mostly called ETL or data pipelines.  There are various tools out there to work out these Extract, Transform, and Load (ETL) operations.  Some of the scripting tools are:  - Python - SQL and NoSQL Apache provides a wide range of products that can be used as Data Engineering tools.  Some of the amazing apache DE services comprised of; - Hadoop - Spark - Kafka - Cassandra - Hive In addition, some cool DE tools are: - Tableau - Talend - MapReduce These DE tools provide a way to manage the data pipelines in a more effective, efficient, and better way.  Almost every Data-Oriented company in the corporate sector is highly dependent upon these technologies. They are leveraging many of the above-mentioned mechanisms for promising Data Services and Architecture. That's it for today. Hope you have enjoyed this article. If you want to know more about data or software related concepts, let me know in th

Applications of Data Engineering

In a previous blog post about data engineering, we went through several many concepts related to data engineering such as data modeling, and then we went through different types of databases, for example, relational databases and we also got a glimpse of relational as well as NoSQL databases. And in today's blog post we will be writing about data engineer applications. Which are basically the use cases of data engineering 1st let's see what data engineering applications mean; so basically when we have data and we have engineered it then there are several things that we can do with that data and these things that we can do with processed data are the use cases of the data engineering. For example: If we have filled our containers with the data then it's not of any good use if it is not clean and well-formed. If your data is well-formed and if there are no logical mistakes, missing values, and garbage then we can easily perform the use cases and applications of data enginee

Web Services : AWS (Amazon Web Services)

-

We have discussed the concept of cloud computing in the previous blog post.  If you want to host your website then you will buy a hosting and if you are not using cloud computing service then that web hosting service is a traditional web hosting service. But... If you are using cloud computing as you want; scalability, security, accessibility, availability and flexibility with less work done by yourself, then there comes AWS  (Amazon Web Services). AWS is the first (to my knowledge) cloud computing service provider. It is the daughter company of Amazon. Amazon.Inc was established almost 24 years ago by Mr. Jeffery Preston Bezos . And  about 12 years ago, Amazon.Inc launched a web service naming Amazon Web Services or AWS.  AWS provides a cloud server and you can do a lot of things using that cloud. Main services/products provided by AWS are:  Analytics Application Integration AR and VR (Augmented Reality and Virtual Reality) Cost Management Block Chain Business A

Yes, you have to take notes in the university class!  Before talking about the notetaking strategy, we will understand the importance of taking notes. Importance Of Taking Notes No doubt there are a few students who can produce good results without even taking notes in the class. But their number is least. Most of us need to make good notes in the class especially when we are in university. Notes are important because: They help us to keep track of what we have studied in the whole semester. Notes help us to prepare for the exams, in a very short time. We can refer to our notes for short quizzes in the eleventh hour. In addition to reading and listening, writing notes increases the ability to memorize the important concepts. It helps you to realize that you have done something in the class. Now that we have understood Why to take notes? Let's dig into the notetaking strategy  Notes taking Strategies One of my friends Ramlah Aamir Aziz used to take note
