Unix Commands

On this article Coder by Gleentech will teach you how to terminal commands from BSD systems.

Today we saw a growth in Unix and Linux as smartphone, embedded systems. Sometimes we encounter FreeDOS. But nowadays the ecosystem we see is Unix and Linux. Those two systems can be found on iOS and Android systems, besides ChromeOS. In this article, I will teach the basics, the basic

commands to manipulate easily your system.

I will teach how to use list directories, change directories, count words, use grep for debugging, and pipelines. This is an article for introduction is not a hard way article to achieve everything. I want to deliver an easy way to get deep into it. Learning Unix is not an easy task, it takes time. You cannot learn everything in one day about Unix. You need to learn and read tons of papers to have knowledge.

For start, we will go to call the terminal. It’s a command prompt. You must call konsole or terminal application. I am going to have all the examples with konsole.

The first command we see is ls.

As we see we can list a directory.

We see with this command the working directory

Why did I choose 4 languages for 2022

Why did I choose 4 languages to code for 2022?

This new article from coder by Gleentech is about an opinion I am giving to all my readers on our official website. I wanted to write about which languages I chose but I see a lot writing about this but I am writing too. I decided to write because I wanted to show which programming languages I chose to code. I have been coding these languages over the last 4 years.

I have been coding nativescript as a new over the last few days. I made two applications already.

With nativescript it’s a good tool to code in Javascript with a few frameworks. I am working with nativescript because Cordova ceased their activity over apache. I was a Cordova developer. Now, I switched to telerik nativescript. It’s an open source tool to make iOS and android applications with javascript. I chose to use nativescript with vuejs. I am learning vuejs too. I decided to focus on nativescript, qt and coldfusion.

Today, we don’t need to focus with a lot of languages because you don’t need to know a lot. It’s better to know a few and focus on them.

This article is ready for 2022 new year’s day. It’’s focus on my knowledge to speak freely, to show which are the main goals for 2022.

I am very focused on to show my needs turned to yours. Try to focus on these four programming languages.

This will be my last article on coder by Gleentech before New Year’s eve and Christmas.

I chose 4 programming languages which are Java, C/C++, Javascript, typescript.

Java:

This language is highly used on big companies. It’s a good language to learn. First try to understand what is a VM(Virtual Machine) and their properties before into deep. Java was a coded language from Sun now it’s an Oracle product. Today, this language is highly used for enterprises, big applications. With Java I chose coldfusion to code because its a powerful tool to design websites for companies.

C/C++:

I chose C/C++ to code for the operating systems application and tools. I learnt C and C++ in high school and before that. I use makefile to compile the code. Today, I am learning to use C++ with cmake also under qt5 and qt6. Nowadays, the qt is a high powerful tool to code GUI and powerful GUI applications. For C and C++ I use vs code and Netbeans also qt creator for coding qt widgets.

Learning this programming is a valuable asset. Almost everything coded for operating systems even kernel is coded with C and C++. I like very much this language because it was one of the first languages I learnt beside visual basic 6. Nowadays, we can do high profiling applications with so many tools out there like vagrant.

Javascript:

This is a programming language type script, which is embedded to web browsers. Today, knowing this programming language is a valuable knowledge too. We must know javascript to make websites and native applications for iOS and android. With this programming language you can code html, css and javascript with frameworks and turn the website into a native application.

You can learn how to use parcel or babel to make front-end Nodejs websites besides backend.

Today, you can use Javascript for front-end and backend with v8 engine. There are so many tools out there to help you out. It’s highly recommended to learn Nodejs. With Nodejs you can code a lot of things. The npm is a tool to install plugins for Nodejs. It’s highly customizable.

I chose Javascript to code all my web content and management.

Typescript:

It’s a superset from Microsoft open source for javascript came 2012. It’s a highly typed language. It’s mostly a highly powerful typed language. This is a powerful toolkit. It’s a powerful programming language. It’s a true highly typed language.

Because of these languages, I chose nativescript, qt, coldfusion to code. With these tools, I can code for iOS, android, web and desktop applications.

With nativescript I can code iOS and android with html, javascript, css and typescript. Under nativescript we can code with angular, vue and ionic frameworks.

I am very focused on this tool. It’s very powerful. I am a newbie on these roads, but I am learning over a book I bought it in amazon. I can run now two applications that I made. I am building a new one, focused on supabase data management. I am learning lucee too. It’s a java coldfusion enterprise edition. I made a few articles that will come out soon about coldfusion. For web are these two powerful tools to make our needs.

For me, teach and learn C++, I code qt5 and qt6. I am working with qt over the last 5 years on my Mac. I am coding qt too on a Ubuntu VM under virtualbox and vagrant.

-For my opinion never learn too many languages. If you learn you are not good in all.

You may focus on 3 or 4 languages and practice them all, to become good in all. I learnt a lot with my dad coding. He told me to focus only on 3 or 4 languages and keep practicing them. So, my goal and focus are C/C++, Java, Javascript and typescript. I am focus on all these besides had the newbies knowledge of vuejs. I am trying to learn vuejs framework for frontend Nodejs. We can learn express too for backend Nodejs. You must focus on these or choose the right languages you want.

After this, you can also learn php. You can learn php because the majority of the simple web hosting are php with WordPress. You must learn WordPress too well. Mostly the websites are php, WordPress hosting. The majority of the websites I build over the last 10 years were WordPress.

I won’t give up from it, I will code and still code php for WordPress because the people want cheap solutions and web application too. You must as reader try to understand our coder by Gleentech opinion as a constructive assessment. We as a magazine we try to solve solutions to you and back to you.

WordPress:

I choose WordPress with php to code the main core of the majority websites I am dealing with in the last 9 to 10 years. It’s a powerful CMS, well documented. We ca deal with APIs too. We can manage our all website from a backend. This CMS is a must to code, frontend and backend and split of, it’s a monolithic structure. Before you dive into WordPress try to learn about the structure and some php code. It can be your strength power tool to manage all your websites. Follow the steps very careful to code php inside WordPress. For that I will teach as a reader php before dig into WordPress.

You can learn how to manage, code a theme, a plugin. Otherwise code the instalment after you install on a local machine. If you want to code and learn it with a word-press instalment you will need to have an ide, for that I choose VS Code or Netbeans from apache foundation.

Nativescript:

Its a powerful tool to code html, javascript, css, scss into a native application for iOS and android. I am talking about it because I chose it to code instead. The defunct cordova. It’s highly active.

Today, I will keep coding on this platform, for me it’s the future. If you know web, you can code easily on nativescript. First teach yourself vue, ionic or angular. These frameworks are highly used, so you can use them.

Qt:

You must learn qt, for me it’s a powerful tool to code in C/C++. Today with the new qtcreator you can code with cmake instead make or qmake.

We must learn cmake nowadays. It’s a good tool to learn. We every day, we are learning and teaching by us and from others.

This article it’s a must to see. It teaches you how to choose the right programming languages and the right tools to code. I hope to see you on the next article. I hope to see you next time.

Coldfusion and heroku

Welcome again to coder by gleentech. Today we will introduce how to code coldfusion and heroku hosting.

Coldfusion is an old architecture for server-side since 1995. It works on the server-side. It’s a tag language. Written in JAVA. Since the rewritten in java since 2002, the tags evolved so much. It can be written with html5, css and javascript. There are a few tags for generation forms. On this tutorial I will explain how the heroku interacts with coldfusion (Lucee version)

Go to lucee website and download the file. It can be downloaded as jar or even in war file.

Download the GitHub as it follows for our example.

-> git clone https://github.com/mikesprague/lucee5-heroku

-> cd lucee5-heroku && mvn package

-> foreman start

You will need to register for an account on heroku and create an app for the tutorial as it follows.

Then you will need to clone the deploy from GitHub online on heroku.

Now, open your folder on the Netbeans. Go to webroot, open index.cfm then copy paste:
