ProCodeCG Kids Coding Camp – Python Programming – Day #3

The last day of Kids Python Programming Coding Camp 🙂

Veyzha actually learned two things today: Python programming and GameMaker 😀 Veyzha had successfully made a simple calculator GUI in Python and then helped Kenzie to do the same thing 🙂

Kenzie finished the task to create a simple calculator with GUI and explore simple artificial intelligence in Python 😉

Vius had completed lots of difficult challenges. Including creating a pizza restaurant form that can calculate the price and the discount for different kind of pizzas and different kind of toppings for each kind of pizzas 😀

Ren finished task very quickly today 🙂 He went through encryption, decryption, virus, antivirus and encryption-decryption virus then simple artificial intelligence 😀

Ren helped Veyzha to debug the program 😉

 

Capt. Faris created his own applicable app with Android Studio 😀 Awesome 🙂

Our incredible Python Programmers 😉 Veyzha had to leave earlier so there were only 3 of them at the end of the class 🙂

Glad to be able to produce another class of Python Programmers! See you again kids, now you have the skills most people want so bad 🙂

ProCodeCG codeMeetUp() #108 – Exclusor – CryptoEconomics

Today, we had Founder of Exclusor, Tata Tricipta, sharing about CryptoEconomics on ProCodeCG codeMeetUp() #108 🙂

About Exclusor (from the WhitePaper):
“Exclusor introduces a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. Reducing energy consumption and high cost in block creation, thus lowering the customer fee unlike current blockchain transactions. This can be achieved by implementing new consensus algorithm and deploying consortium network model.”

We set up the room while waiting for more people to come 🙂

This is a very recent topic involving cutting-edge technology 🙂

Introduction about Blockchain

The ecosystem

What is cryptoeconomics?

Implementation of cryptoeconomics

Exclusor protocol

Exclusor Decentralized Autonomous Organization

IDAEX

Some notes

and some more

The audience

Us 🙂

QA Sessions and discussion after the presentation 🙂

ProCodeCG Kids Coding Camp – Python Programming Day #3 – 31 Dec 2016

Day #3! We’re ready to create some virus, infect some files and recover them using anti-virus 😉

Zaky

Dea

Abit

and Arya couldn’t wait to see how viruses work 😀

We learned two virus today: a duplicating self virus and an encryption virus 🙂 For each virus there is an antivirus.

The code for each one is very long and cryptic

It took a while to type and debug it 🙂

Plus we have to be extra careful running the virus, otherwise the whole directory of python work for the last 3 days will be infected 😀

We had to quarantine the virus in a separated folder to make sure it only infect the files we wanted to be infected 🙂 Notes: running anti-virus will clean the virus file too 😀

This is how the kids look like after hours of virus-antivirus coding LOL

Dea had just lost her virus wiped away by the anti-virus, Abit start massaging his shoulder due to long typing, and Arya said “Ka, I’m giving up typing, can we take a break” for the tenth times 😀

So Capt. Zaki had to copy the virus file to Arya’s laptop after Arya promised he will type the anti-virus 😀

While Capt. Fizhan specialization is still: babysitting 😀

Here they are: our kids python programmers! Watch out world! They can encrypt, they can decrypt and they can create viruses that encrypt!!! 😀

The screenshots of our codes today 😀

Next week we will start Creating Apps and Arduino Programming Coding Camp 🙂 Will be reporting very soon! Happy New Year! 😉

ProCodeCG Kids Coding Camp – Python Programming – Day #3

The last day! We learned to create virus, and the antivirus of course! 😀

Before we learn how to create virus, we have to learn how to write to and read from a file 🙂

We also have learn how to find files in directory

or finding a specific file

Then we can start create the virus

The virus is not dangerous, basically it just makes a copy of itself to another file, and only .py files 🙂 The antivirus is simply deleting the virus body from the infected file

We also created an encryption virus using a simple substitution cipher

The antivirus is simply reversing the process which is decrypting using substitution cipher 🙂

Some kids arrived late so we waited a bit before starting the class

The class (only missing one kid who didn’t feel so well today)

Each piece of code is being tested. This is the view of Capt. Zaki laptop’s screen.

Lots of code needs debugging, Capt. Zaki handles two computers at the same time 😀

Busy captains

We finally finished all the codes!

So it’s a wrap! 🙂

Tomorrow we will learn how to create apps for android 🙂

This is us on the way home, fully packed on the back seat LOL

Until tomorrow! 😉

ProCodeCG Kids Coding Camp – Python Programming – Day #2

Today we learn about cryptography 😉

We started with substitution cipher 🙂

We did encryption and decryption, and brute force too 😉

We modified the code and added some while loop

And there was a quiz to be solved 😀

Next was Vigenere Cipher, a bit harder but we did it 😀

We did encryption and decryption in Vigenere, and modify it from uppercase to lowercase

We read several references too to make sure we understand how it works 😉

ProCodeCG Kids don’t just code, they read books too 😉

This is the scene in the morning 🙂 We prepare the class together, and this is the values being taught in ProCodeCG: teamwork and sharing 🙂

Capt. Zaki explained the brute force process

Our Lead Captain is very reliable 🙂

Capt. Azriel working on modifying the encryption code too 🙂

This one is too tired LOL

But we will be alive and kicking again tomorrow to learn how to make virus and antivirus in Python tomorrow! 🙂

ProCodeCG Kids Half-Day Coding Camp Virus Antivirus Day #2

Virus Antivirus Coding Camp Day #2!

Day #2 is always when the kids start to know each other 🙂

The girls tend to be quiet and consistently pay attention while the boys started to gather and make noises 😛

Today we start creating the virus, and see how it worked 😀

This one always freaked out about running the virus because he had just heard that the captain got python-based game stopped working infected by the virus LOL

But we finally finished testing the virus and created the antivirus to recover all the infected files 😉

We also learned about some encryption and decryption, because tomorrow we will make encryption virus! 😀

This is how the virus and the antivirus look like 😉

We’ll be reporting again tomorrow! 😉

ProCodeCG Kids Half-Day Coding Camp Cryptography #3

Hello! Today is the 3rd day of ProCodeCG Kids Half-Day Coding Camp Cryptography 😉

Setting up room and prepare for a class has been a great way to start the day 🙂

Why take a holiday if work is so much fun? 😉

Yeaaay kids started to show up and ready to pick up where we left yesterday 😉

They couldn’t wait to start the class and to see each other too!

Today we modify our previous code to have some awesome GUI 🙂

It took some time to work things out to get the code we want but we shared ideas and took turns to solve the problems.

Coding on the spot is better than preparing a ready code because it will ignite the kids to be involved and be creative.

When we got stuck, our reliable captain Zaki is always ready to google and find some solutions 😉

The kids will help each other to make their codes work

When the chief instructor got stuck, the lead captain got stuck too, there will be another kid find the solution 😀 This is Vai working on the main laptop to make the code work (we want the encryption to include some spaces 😀 )

When the kids got tired, they just took a quick break like this LOL

Or, teasing each other like this 😀

But when they are serious, they look like this. Eating while working 😀

Today we learned about Vigenere Cipher! This is Farrel reading the look up table to see how the cipher work!

And this is us with the certificates YEAAAYYYY

After the class. They wouldn’t stop playing together 😀

The most beautiful thing in camp like this is that the kids find new friends, make new bonding, create new things and be back home happier with loads of new experience!

They had packed up things but just couldn’t leave their friends 😀

While some of them still working on the computer (even that the main laptop had been shut down)

Look how happy they are!

See you on the next coding camp, kids! 🙂 😉 ❤

Here are some of what we did today 😉

ProCodeCG Kids Half-Day Coding Camp Cryptography #Day 2

Today we started to do encryption and decryption with substitution cipher!

Preparation before the class started

Digilife Dago is a very nice and comfortable place, we have great internet connection, accessible power sockets, air conditioner, super big screen, clean toilets and a very friendly and nice musholla.

Most of the kids continue their codes at home and show it to their friends in the morning 😉

Some kids came late due to the heavy traffic, but they quickly set things up to catch up with the class.

We only have one female student (plus one female captain) in this batch 🙂 Not many girls interested in coding, probably because it is some kind of intimidating? 😀

We started encryption and decryption with Caesar Cipher.

We encrypted some messages and then try to decrypted them.

We also learned how to do the brute force! This kid (Farrell) count each letter just to find out the key! LOL

Yeah, and of course, kids love to play during the class 😀

 

The best thing of gathering kids in a class is when they working together and share things

Give them challenges, and their bright brains will surprise you 🙂

We also learned about ROT13 🙂

And encrypted and decrypted LOTS of messages!

We also made a decryption competition 😀

Some people might say that programmers have no life. That’s not true! 😉 Look at how much we are having fun!

 

Lunchtime. LOL (with hood and all) LOL

After the lunch we learn some password breaking logics.

Also about One Time Pad encryption.

We learned some GUI in Python too, to make the code user-friendly!

Coding and cryptography might sound pretty darn serious but look at these kids! No frowns at all! 🙂

  

And these are the screenshots of a bit of what we’ve learned today!

Tomorrow we’ll do more encryption and decryption!!! With Vigenere Cipher 😉

ProCodeCG Kids Half-Day Coding Camp Cryptography Day #1

Hello! The Cryptography Kids Half-Day Coding Camp began today!

We came a bit earlier so we had to wait a bit until the building is ready 🙂

Kids getting along easily. Several of them didn’t know each other but they quickly share things and became good friends 😉

Before we entered cryptography, the pre-requisite is to be able to code in Python. So we did some installations before the class started.

Some of the kids already had Python installed (from the ProCodeCG Kids Camp before 😉 ) but they forgot how to load it and start to type in code, so we started from the very beginning to make sure everyone understand.

Yeah. We started type in code in Python (so happy to have this big screen! 😉 ❤ )

We started from a super simple code (2 lines) to more complex code (40-50 lines). And the kids didn’t mind typing it 🙂 Well, because coding is not just about drag and drop 😀

And after they typed it and compiled it and see how it worked, they start modifying it (like changing the variables into very huge numbers) and laughed about it LOL

The result 😀

And another 😛

We also explored about more advanced thing like finding prime numbers 😀 Because kids need to be challenged!

And they can do it! 😉

They are not just coding. They make bondings as human as well 😉 Look at these kids 🙂 ❤

Friday Prayer break 😉

And the program is still running on some computers 😀

After Friday Prayer, we got newcomers! Vai and Tio. They catched up quickly!

We continued coding while having lunch 🙂

One of them said that he made 1000000 loops so the program was still running when he got back from the mosque LOL

This kid, Hilmi, use 2 computers 😀

This one, Farrell, should apply job as code tester LOL He always eager to find ways to make the code stop working or the computer got hang 😀

The kids answered all the challenges so the difficulty escalated 😀 we created 5 loops in a code just to see how it worked.

This is some screenshots of a small part of what we did today!

Even after the class, the kids wouldn’t stop because they really wanted to solve the problems 😀

And this one also, ask his mom to give him 1 hour extra time 😀

Don’t worry kids we will do this again tomorrow insyaAllah! See you soon! ❤ ❤ ❤

ProCodeCG Talkshow on KLCBS 17 Dec 2015

Today we had a talkshow at KLCBS about the upcoming ProCodeCG Half-day Kids Coding Camp 🙂

The registration is still open, you may send your kids to more than one topics (Games Development, Cryptography, Virus-Antivirus).

Games Development topic will introduce kids to programming using games. They will learn different tools and languages to create games. And at the end they will be able to create their own games.

Cryptography topic will give awareness about security of data to kids. They will learn how to protect their data with encryption. Later their problem solving skills will be improved by learning how to decrypt their encrypted data.

Virus-Antivirus topic will provide the kids with knowledge about malware threats. They will learn about different kind of virus, the level of dangers and how to prevent the threat. They will learn to create simple and less harmful virus to see how it works. They will also be taught on how to create antivirus to the virus they created.

Each topic will be in 3 days, from 9am to 2pm. Kids will learn from beginner to advanced level on each topic.

Don’t worry if your kids are beginners because we will start from the beginning for each topic!

Age doesn’t matter too, we have several Captains on different ages to make sure your kids keep up with the class.

Each kid is expected to bring a laptop and a table. We will provide internet connection, snack, lunch, souvenirs and certificate. And course materials 🙂
