“There are only two industries that refer to their customers as 'users': illegal drugs and software. " — Edward Tufte

I took the time yesterday to watch the Social Dilemma on Netflix and it is so important to watch.
10/10 recommendation.

Make the time to watch it. Image
I actually made a presentation on this topic like 4-5 years ago on how our phones were going to know what we want before we even realized it because of all the data and models they would have of us.

Turns out they were already doing it at that point in time 🙃!

#BeAware
It really hit hard when I saw the numbers on how this affected kids and teenagers.

Please make sure you watch out for these problems, if we as adults can't even control ourselves imagine the burden on them that are still developing their character and personality.
And lastly, if you have already watched it, what hit you the hardes? What surprised you the most? Share and lets talk about it!

Agile this, agile that, everyone uses agile and few teams develop "agile-y".

If you are preparing for an interview you need to know a couple things about Software Development Methodologies!

This is the tenth and last thread of the series: Interview Preparation!

🧵THREAD🧵
First, let's get some facts & definitions down.

A Methodology is the systematic study of methods applied to a discipline.

Software engineering is the practice of using selected process techniques to improve the quality and results of a software development effort.

⬇️
There is 1 more, it is important, bare with me.

Software Development Methodology is the collection of policies, processes, and procedures used by a dev team or org to practice software engineering

So basically, methods and rules to develop software in an engineering manner

If you are tired of breaking environments or you keep hearing about DevOps but have no idea what that is...
Then this thread is for you!

Let's talk about CI/CD!

This is the ninth thread of the series: Interview Preparation!

🧵THREAD🧵
First, let's get some definitions down.

CI = Continuous Integration
CD = Continuous Delivery / Continuos Deployment
DevOps = Combination of practices of Software Development (Dev) and IT Operations (Ops)

Let's tackle these concepts and it¿s tools and practices

⬇️
CI/CD is a set of principles and practices to deliver code changes more frequently and reliably

It is one of the best practices for both DevOps teams and agile methodologies, as it goes hand in hand with their objectives:
- Focus on business value
- Code quality
- Automation

Most of the systems you will build in your life will need some form of persistence.
That is why when preparing for an interview you should be ready to talk about Databases

This is the eighth thread of the series: Interview Preparation!

🧵THREAD🧵
First, let's get some definitions down.

A Database is an organized collection of data.

A Database Management System (DBMS) is a software for users to define, create, maintain & control access to the DB.

You will also need a language to program and design your DB objects.

⬇️
There are very different types of Databases & also a lot of possible classifications.
I would say the most useful one is:

- SQL
- NoSQL

We are going to focus only on SQL Databases in this thread.

You can read MANY more classifications here:

For sure the most frightening part of any interview is the: ALGORITHM EXERCISE!

This is the fifth thread of the series: Interview Preparation!

if(self.wantToPassInterview){
self.readThread();

}

⬇️
Not every company evaluates this the same way.

If you are thinking about FAANG companies or similar this is probably the most important topic. Otherwise, this is still a big topic to cover but don't neglect the others

We will cover a roadmap for Algorithms & Data Structures

⬇️
First let's talk about some easy problems that are widely used in interviews, make sure to be able to solve them.

Read each of them and think of the solution now...

If you can't figure them, search on youtube, there are plenty of videos explaining and solving them.

If I had to recommend you to learn 1 topic for any FullStack Web Developer role it would be: Javascript

This is the fourth thread in the Interview Preparation series.

new Promise(youWillLearnSomething)
.then(leaveALike)
.then(commentBelow)
First things first, javascript can't be fully explained in a thread. I will give you pointers and common questions and some advice

Please take the time to learn and practice JS
Some resources:
freecodecamp.org/learn/javascri…
theodinproject.com/courses/javasc…
Youtube has plenty of JS material

⬇️
Javascript is a programming language, the one native for web browsers, and one of the most used in the world.

It allows you to create a front end, back end (node), and even mobile with some magic in the middle. Let's go through the fundamentals that you should learn.

Now it's time to get into the specifics. Do you know how to build Front ends?

This is the 3rd Thread on the series of Interview Preparation

Let's get started!

🧵Thread 🧵 Image
A quick note here: This will focus on web devfront end (some things apply to mobile too), but keep in mind if the position is backend developer, desktop developer, or other fields some things might not apply.

This would be the standard front end check for FullStack Web devs.

👇
First of all, you have to understand:
* What is the Web
* Server-client relationship
* How in the end our web browsers can only process HTML, CSS, and Javascript.

You can read a little bit more here in a short article I did some time ago:
