Getting AWS Certified Developer Associate (DVA-C02) in 2023

pacozaa — Sun, 30 Jul 2023 08:09:46 +0000

I just got certified on 24 July 2023 and would like to share the experience and the learning strategy with you.

Let’s start with the phases I am going through.

Phase 1 — Getting Started with the Course

In January, I started off by watching this course by Stephane Maarek

https://www.udemy.com/course/aws-certified-developer-associate-dva-c01/

The course is very effective and covers everything you need to know to get the certification. It also provides a hands-on lab every step of the way to help you understand at the practical level. This hands-on lab is a must if you’ve never touched or not working day to day with AWS.

In this course, the instructor provides you with a lot of good tips and highlights important things worth noting, and explains everything with good comprehension.

Please do all the hands-on, it really does help.

After I finished all the videos and hands-on, I thought, I am ready to take the exam, then I started doing example practice exams in the course and realized I got more work to do.

Phase 2 — Practice, Practice, Practice

After I found out that I need more practice, I gather all the material I can afford.

Here is a list

The way I do it repeatedly is, I take the exam either entirely(65 questions) or 5–10 questions a day until finished then I started to review the incorrect answer and study them. And start again for the next practice exam.

At my best, I keep doing it every day with pen and paper then life happen it became every other day. I find that 5–10 questions a day is better than nothing, even 1 question a day or 1 incorrect answer a day is still better than nothing. If you can’t do 1 question, just read the question and answer the next day.

I recommended you keep note of your score and see how you progress over time, that will help motivate you.

Also, If you get bored over time, you can switch up to doing self-assigned challenges generate by chatGPT, it’s pretty fun. But remember to get back to exam practice after using hands-on challenges to help understand things in action.

Phase 3 — Book the exam

After I went through half of them I started booking the exam and I did it. Personally, I would say pick 1or 2 of those 3 practice resources would be enough to pass the exam.

I bought 3 of them because I got caught up in the day-to-day work and pause for a couple of weeks. I just needed more practice to come back on track.

Last Note

Set your calendar when you are going to take it. I recommend the online version.
Build a small habit to study every day or every other day.
Compare to CKAD, AWS CDA DVA-C02 is much harder since there are tons of content to go through, understand, and space repetition over time.

Exercise For Every Programmer

pacozaa — Fri, 17 Jan 2020 02:20:11 +0000

A few years ago, I just realized back pain is a common health problem among programmer and office worker.

I am also have faced the same health problem and started to study "working out" and decided for the first time ever in my life to go to the gym.

And after trial and error, I accidentally find out this tremendous exercise among big gym bros, have helped me fight the back pain back.

It is a DEADLIFT.

Try it out, within a few weeks, your back pain will go away. Use challenging weight and study the exercise on youtube. It will help!

Diary - React Native TESTING !@#?

Well, this will be random.

I am currently trying to add Jest to my one-year-old mobile apps. It has been developed and improves constantly and now to a point where I want to have solid testing in my skill set.

I was trying an automated test with Detox then I hit the problem that it is so difficult to solve the problems.

I can't tap on system permission popup on IOS.
I can't make it work with android.

Then I step back a little bit.

I have tried to use Jest with react native before but the project stated and timing seem to be too short and have to skip unit "testing".

But now I am ready to tackle the problem again.

I started with small and little cute components and it works!

SNAPSHOT - Huray!

then I step up a bit and work with "Home" component. It doesn't work YET.

what I have done so far is configuring jest and mock function left and right then I hit the big function which I am right now too lazy to mock. I am looking for cleaner solution rather than mock my way out to freedom.
