Recently I had a webinar (in Armenian) where I was talking about programming languages and stacks, their differences, and how to choose one.

## Web Applications

When speaking of web apps one should imagine sites that he is using every day. They usually consist of two parts: frontend and backend.

> Frontend — is the practice of converting data to a graphical interface, through the use of HTML, CSS, and JavaScript, so that users can view and interact with that data. (Wikipedia)

HTML stands for hypertext markup language — the backbone of every page that lives on the web.

> Hypertext is the text which contains links to other texts. (Ted Nelson, 1965)

CSS stands for Cascading Style Sheets and its main purpose is to make sites look gorgeous.

And JS stands for the most popular language that millions of people use daily.

> The front end is an interface between the user and the backend. The backend has three parts to it: server, application, and database. To handle the backend of given applications, programmers or backend developers have to deal with backend technologies that include languages like Java, C#, Python, Ruby, Node.js, PHP, and many others.

One of the groups of backend languages includes those that have a strict type system and tight coupling with OOP ideas. These languages are Java, C#, C++, and many others. They are very popular among big enterprise companies due to their strictness and safety. Usually, newbies find them hard as a first language because of the high entry threshold.

Another group of languages includes those that have a dynamic type system, mostly they are multiparadigm with a low entry threshold. They are easier for learners because you can jump into the language very fast and see the result. JS (Node.js), Python, Ruby, PHP are the most famous languages. Big tech companies, like Twitter, Github, Basecamp are using Ruby (and Ruby on Rails framework) for backend development. Facebook and VK have been created using PHP (at least first versions).

Pros of web apps:

- One development team for all Operating Systems (user only needs browser)

- Development speed due to the infrastructure of libraries and frameworks which allow solving almost all problems.

- Low entry threshold

Cons of web apps:

- They lose to native apps because of the lack of access to hosting platforms (for example, Notifications, GPS, Cameras). Although I hope that Web 2.0 and PWA's will change the situation and WEB will be great again.

- There's no way to create high GPU-consuming apps (like big games) in WEB.

## Mobile Applications

Researches by Statista are showing that in the third quarter of 2020 the half of the traffic worldwide came from mobile devices. I'm almost sure that half of the readers are also using mobiles so there is no need to describe what mobile applications are.

What is not clear when we're speaking about mobiles is their types and what languages one should master to start coding. To clarify that, let's explore three approaches to mobile development.

### 1. Hybrid applications

> A hybrid app is essentially a combination of a native app and a web app. Although this type of app can be installed on a device like a native app, it technically is a web app. These types of apps are built with HTML, CSS, or JavaScript and run in a web view.

So technically you still are writing your HTML, CSS, and JS
 code like you was doing in the case of web apps but now you're running the code in a web view.

One might think that this is brilliant technology and we should use it as a standard because now we can share the code between web and mobile, but things are not that easy. Hybrid apps are not showing good performance: apps are freezing and their UX suffers a lot (you can sense that even physically that the app is written for the web, not the mobile world).

### 2. Native Applications

When speaking about native apps, we should mention that there are two major operating systems for mobile: iOS and Android and both of them have their languages with big ecosystems.

For many years in the iOS world, the main language was Objective-C but then apple presented Swift which is easier for developers and now it's a de-facto standard for iOS applications.

In the case of Android, there's the same scenario, Java was the main language but then JetBrains presented Kotlin which took part in the market.

Native Apps had better UX due to their connection with host OS and direct access to the Notification, Camera, and other APIs.

At the same time, companies need two development teams to handle both Operating systems because it's not frequent when one developer knows both languages. It's the main disadvantage of native applications.

### 3. React Native

React Native combines the best parts of these worlds: it allows to write code that runs on both Operating Systems (actually 70-80% of the code), it allows companies to use frontend developers and their knowledge of JS and React and during the parts where React (and js) are close to their limits (GPU-consuming operations), you can write code on Swift or Kotlin and connect it with React Native via the so-called bridge (see RN docs for more info, it's really interesting. I promise).

## Desktop Applications

The desktop world is similar to mobile. As the main advantage, we can see better UX because of the access to the Host Environment.

And as in mobile, here in Desktop, there are two popular approaches to development.

1. Native Applications
   Here we can use a lot of languages, like C# (created by Microsoft and works great on Windows), C++, Java, etc. The only problem is that in some cases we need multiple languages for different Operating Systems.

2. Electron Applications
   JS Ecosystem has reached even this point and using HTML, CSS, and JS we can build cross-platform desktop apps. VS Code, Facebook Messenger, Figma, WhatsApp have been created with Electron. Also, it worth mentioning that Electron applications are cross-platform which means the code can be run in different OS environments.

## Machine Learning

There are many languages that one can use for creating ml products: Python, R, JS, C, C++, Java, C# but the big part of the market are developing the products using Python because of its big infrastructure: tons of libraries and platforms like Tensorflow are available for Python (also for JS). That's why Python is the number one choice for ML.

## Tips

Finally, we know about most software application types and now we can create an algorithm for picking a language and our algorithm will base on three criteria.

### Skills and interests

If you are interested in visual information representation and working with the product that end-users are gonna face, then maybe frontend, mobile or desktop stacks are for you. Elsewhere, if you're not interested in visual and more in data processing and manipulation then you should consider Back End or ML stack is right for you.

### Mentors and Environments

Mentors and people who surround you are also very important. So if most of your colleagues and friends know any programming language, then you should consider that one because their role in your first steps will be crucial.

### Languages by market

The one thing that newbies should also take into consideration is the market. If there's no need for developers for the language that you consider then maybe it's not the best option. That's why it's really important to check what the market needs. I'd recommend to stard with [Stack Overflow survey](https://insights.stackoverflow.com/survey/2020) to understand market needs better.

## Experience

I chose JS and React Ecosystem because of their cross-environmental approach. JS and React are being used in Web, Mobile, Desktop, and even ML which allows me to focus not on technologies but on creating applications. I also understand that JS Ecosystem is not the best performance-wise and sometimes reaches its limits but in most cases, it gives me tons of other benefits.

I hope that I helped to create a framework that will help you to find your language and most importantly, your ecosystem.

How to choose a programming language?


Today I turned 24. Usually, people of my age share lessons they learned
at they b-day. I won't be an exception and here is my lessons (oops, lesson!) ⤵️

If there is one truth I learned at my 24 is that awareness matters the
most: via meditation, mindfulness, or even basic breathing practices.

## why

  ] show that mindfulness practices can help you to be calmer about the
  decisions you make even under the stress, be happier and see beauty around.
</p>

Every time I bring more awareness to my life, the overall quality
of life changes.
I become happier and less stressed, I sleep much better and calmer, waking up energized
(tracking sleep and stress level via [mi band](https://www.mi.com/global/mi-smart-band-5/) or any other smart-watch can help to measure).

### rest

Most of my friends and colleagues are complaining that they don't know
how to rest.

Awareness techniques are the first steps to give yourself a better treat both
mentally and physically. They help to explore true desires and find the activities
that help you to rest.

## faq

Note, that

1. Some of the practices might sound hard at first glance, don't fall into that trap.
   Use links [bellow](#how-to) to find out more about practices for beginners and
   how to bring them to your life.
2. Spend as much time, as you feel like even if it is 5 minutes daily.
3. Regularity is key. Awareness is not a one-time thing. Don't even hope.
4. Although awareness brings calmness and joy to your life very fast,
   people with anxiety issues might wait for the results a bit longer.

🧘‍♂️ Awareness matters


## Ep 4: Offline Courses Sucks!

Before you close the tab, let me bring some arguments to the table ⤵️

### Attract best talents

During the covid I had several courses where students were from Armenia (both capital and multiple villages) and Russia (even from glubinka). Most of them were great students and they’d miss the class if it was offline.

And the class would miss them.

### Out of box solutions for recordings

Recorded lessons were one of the great bonuses for students. Now they can re-watch the lesson multiple times instead of trying to remember everything. It really improved the performance.

### Less operational costs

During the offline lessons, operational issues were the ones that bothered me the most. Broken projectors, cords, and lines.

Now, the only operational dependency is the internet.

### But what about socialization?

One might argue that communication suffers during the online lesson. Sadly, I have to agree. But! We can and must adapt:

- Peer-graded assignments, Pair-programming, Team Related tasks

> Coursera uses them to solve the problem of cooperation and experience sharing

- Start each lesson by experience sharing

> Evil Martiance use every 10-20 minutes of their meeting time to share their life-related experience

- Online tours

> e.g. visit the Louvre or watch some tv-shows via Netflix Party
