ProCodeCG – BDV – codeMeetUp() #113 IoT Series Day #1 – 6 Nov 2017

Standard

Today ProCodeCG and BDV started Day #1 of codeMeetUp() IoT Series πŸ™‚

ProCodeCG - codeMeetUp() #113 - ProCodeCG codeMeetUp() #113 - IoT Weather Programming Series 1:4 - small

Today we learned some intro about IoT, take a look at some devboards and sensors

IMG_1346 IMG_1347

We used devboard from DyCodeX: ESPectro ver 3 πŸ™‚ It is available on Makestro Shop πŸ™‚

IMG_1348

and then started to install Arduino IDE, drivers and ESPectro Libraries

IMG_1349

As usual, the beginning is always painful because it takes time to download the libraries, and do the setting πŸ™‚

IMG_1350 2

We had kids in the class too πŸ™‚

IMG_1357

Everybody seemed to have fun, despite of the obstacles (different on every OS :D)

IMG_1352 IMG_1353

IMG_1354

The first group successfully installed ESPectro library and make the LED blinks, plus turned neopixel off. They were given task to make neopixel blink but time was up so we had to continue next week πŸ™‚

IMG_1355 2

ESPectro32 is already available on Makestro Shop, to those who are interested πŸ˜‰

ProCodeCG codeMeetUp() #111 πŸ™‚

IMG_8194IMG_8195

Philosophy of Blockchain by Prof. Budi Rahardjo πŸ™‚

IMG_8196IMG_8197IMG_8198

Blockchain is not equal with Bitcoin

IMG_8199

Example of transaction

IMG_8200

how miner work

IMG_8201

initiating amount of bitcoin for A and A send some to B

IMG_8202

A chain will be created for each transaction

IMG_8203

The transaction will be hashed with certain criteria

IMG_8204

Example of simple hash

IMG_8206

A demo of transaction recording and creating chain in PERL

IMG_8207

creating hash that meets criteria for each transaction

IMG_8208IMG_8209

IMG_8210IMG_8211

the code: generating chain, calculate hash, etc. Showing how mining is done

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 codeMeetUp() #103 – BR – Rock’N Roll History of Silicon Valley

Standard

Our codeMeetUp #103 with Prof. Budi Rahardjo πŸ˜‰ Lots of preparation (like always πŸ˜€ )

IMG_6955

Should we read it “A Rock Star and History of Silicon Valley”? πŸ˜€

IMG_6956

Pak BR brought some books about Silicon Valley to be circulated among the audience

IMG_6960

The story started from the difference between West and East Coast

IMG_6961

The culture

IMG_6962

The universities

IMG_6963

Frederick Terman is the father of Silicon Valley

IMG_6965

William Shockley, who invented transistor

IMG_6966

Story about Traitorous Eight, those hired by Shockley and then later left him and founded Fairchild Semiconductor

IMG_6967

Lucky breaks for Fairchild Semiconductor

IMG_6969

And then came the birth of Intel

IMG_6970

A brilliant and interestingΒ visualization of the creation of Silicon Valley

IMG_6971 2

The MOST interesting thing, though: the hierarchy of great people, from William Shockley to Prof. Samaun Samadikun to Prof. Budi Rahardjo πŸ˜‰ Prof. Samaun was Shockley’s student, and Prof. BR was Prof. Samaun’s student. So all Prof. BR’s student and the audience yesterday have a close relation with the inventor of transistor! How cool is that! πŸ˜€

IMG_6973

Story about Hawlett and Packard, who gave birth to Silicon Valley

IMG_6974

Their first office has this Birthplace of Silicon Valley Monument

IMG_6975

So what are the values of Silicon Valley?

IMG_6976

Can we make Silicon Valley here in Indonesia? In Bandung?

IMG_6984

Why Bandung?

IMG_6985

Bandung has all that science, tech and creative communities

IMG_6986 IMG_6987

IMG_6988

Not on only us trying to copy Silicon Valley, the whole world has been trying to but never succeeded because Silicon Valley is not just a place. It is a state of mind.

IMG_6989
