ProCodeCG codeMeetUp() #108 – Exclusor – CryptoEconomics

Standard

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

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.”

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

Standard

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

IMG_9747

Zaky

IMG_9748

Dea

IMG_9749

Abit

IMG_9750

and Arya couldn’t wait to see how viruses work πŸ˜€

IMG_9751

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

IMG_9752

The code for each one is very long and cryptic

IMG_9753

It took a while to type and debug it πŸ™‚

IMG_9754

IMG_9755

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 πŸ˜€

IMG_9757

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

IMG_9758

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

IMG_9761

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 πŸ˜€

IMG_9762

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

IMG_9769

IMG_9770 IMG_9771

IMG_9772

While Capt. Fizhan specialization is still: babysitting πŸ˜€

IMG_9774

IMG_9776

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

IMG_9780

ProCodeCG Kids Coding Camp – Python Programming – Day #3

Standard

The last day! We learned to create virus, and the antivirus of course! πŸ˜€

Before we learn how to create virus, we have to learn how to write to and read from a file πŸ™‚

Bildschirmfoto 2016-06-29 um 9.23.40 AM

We also have learn how to find files in directory

Bildschirmfoto 2016-06-29 um 9.38.28 AM

or finding a specific file

Bildschirmfoto 2016-06-29 um 10.26.05 AM

Then we can start create the virus

Bildschirmfoto 2016-06-29 um 8.59.06 AM

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

Bildschirmfoto 2016-06-29 um 10.45.49 AM

We also created an encryption virus using a simple substitution cipher

Bildschirmfoto 2016-06-29 um 12.10.11 PM

The antivirus is simply reversing the process which is decrypting using substitution cipher πŸ™‚
Bildschirmfoto 2016-06-29 um 12.11.24 PM

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

IMG_5362
IMG_5363

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

IMG_5364
IMG_5366

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

IMG_5369

Lots of code needs debugging, Capt. Zaki handles two computers at the same time πŸ˜€
IMG_5373 IMG_5374
IMG_5375 IMG_5376

Busy captains
IMG_5377 IMG_5378

We finally finished all the codes!
IMG_5379

So it’s a wrap! πŸ™‚

IMG_5383

Tomorrow we will learn how to create apps for android πŸ™‚

This is us on the way home, fully packed on the back seat LOL
IMG_5384

UntilΒ tomorrow! πŸ˜‰

ProCodeCG Kids Coding Camp – Python Programming – Day #2

Standard

Today we learn about cryptography πŸ˜‰

We started with substitution cipher πŸ™‚

Bildschirmfoto 2016-06-28 um 9.48.59 AM

We did encryption and decryption, and brute force too πŸ˜‰

Bildschirmfoto 2016-06-28 um 9.49.14 AM

We modified the code and added some while loop

Bildschirmfoto 2016-06-28 um 10.38.15 AM

And there was a quiz to be solved πŸ˜€

Bildschirmfoto 2016-06-28 um 11.09.52 AM

Next was Vigenere Cipher, a bit harder but we did it πŸ˜€
Bildschirmfoto 2016-06-28 um 11.41.36 AM

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

Bildschirmfoto 2016-06-28 um 1.15.38 PM

We read several references too to make sure we understand how it works πŸ˜‰
Bildschirmfoto 2016-06-28 um 1.45.21 PM Bildschirmfoto 2016-06-28 um 1.56.23 PM

ProCodeCG Kids don’t just code, they read books too πŸ˜‰
IMG_5307

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

IMG_5308
IMG_5309

Capt. Zaki explained the brute force process

IMG_5310

Our Lead Captain is very reliable πŸ™‚
IMG_5311

Capt. Azriel working on modifying the encryption code too πŸ™‚

IMG_5312

This one is too tired LOL
IMG_5316

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

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

Standard

Virus Antivirus Coding Camp Day #2!

IMG_2776

Day #2 is always when the kids start to know each other πŸ™‚

IMG_2777

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

IMG_2778

Today we start creating the virus, and see how it worked πŸ˜€

IMG_2779IMG_2782IMG_2783IMG_2784IMG_2785IMG_2786IMG_2787IMG_2789

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 LOLIMG_2790

But we finally finished testing the virus and created the antivirus to recover all the infected files πŸ˜‰

IMG_2791IMG_2792IMG_2793IMG_2794IMG_2795IMG_2796IMG_2798IMG_2799IMG_2800IMG_2801IMG_2802

IMG_2803

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

IMG_2804IMG_2805

This is how the virus and the antivirus look like πŸ˜‰

Bildschirmfoto 2015-12-29 um 12.14.31 PM

We’ll be reporting again tomorrow! πŸ˜‰

ProCodeCG Kids Half-Day Coding Camp Cryptography #3

Standard

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

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

IMG_2603IMG_2604IMG_2605

Why take a holiday if work is so much fun? πŸ˜‰

IMG_2606

Yeaaay kids started to show up and ready to pick up where we left yesterday πŸ˜‰

IMG_2608

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

IMG_2609

Today we modify our previous code to have some awesome GUI πŸ™‚

IMG_2611

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.

IMG_2612

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

IMG_2613

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

IMG_2614

The kids will help each other to make their codes work

IMG_2617

IMG_2618

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

IMG_2619

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

IMG_2624

Or, teasing each other like this πŸ˜€

IMG_2633

But when they are serious, they look like this. Eating while working πŸ˜€

IMG_2626IMG_2627IMG_2628IMG_2629

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

IMG_2634IMG_2635

And this is us with the certificates YEAAAYYYY

IMG_2636IMG_2638IMG_2639IMG_2640

After the class. They wouldn’t stop playing together πŸ˜€

IMG_2642

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!

IMG_2644

They had packed up things but just couldn’t leave their friends πŸ˜€

IMG_2646

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

IMG_2647

Look how happy they are!

IMG_2648IMG_2649

See you on the next coding camp, kids! πŸ™‚ πŸ˜‰ ❀

Here are some of what we did today πŸ˜‰

ProCodeCG Kids Half-Day Coding Camp Cryptography #Day 2

Standard

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

Preparation before the class started

IMG_2539

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.

IMG_2540

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

IMG_2542

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

IMG_2543

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

IMG_2544

We started encryption and decryption with Caesar Cipher.

IMG_2545

We encrypted some messages and then try to decrypted them.

IMG_2548

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

IMG_2549

Yeah, and of course, kids love to play during the class πŸ˜€

IMG_2550

 

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

IMG_2551

Give them challenges, and their bright brains will surprise you πŸ™‚

IMG_2552

We also learned about ROT13 πŸ™‚

IMG_2560

And encrypted and decrypted LOTS of messages!

IMG_2563

We also made a decryption competition πŸ˜€

IMG_2564

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

IMG_2566

 

Lunchtime. LOL (with hood and all) LOLIMG_2568

After the lunch we learn some password breaking logics.

IMG_2570

Also about One Time Pad encryption.

IMG_2571

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

IMG_2572

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

IMG_2573 IMG_2574 IMG_2575Β Β  IMG_2578

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