Besut Kode

Workshop 1Google Code-in

John VandenbergMentor Wikimedia

Welcome

Do you want to become a programmer?

It is frequently said that learning to code is as important as learning language and maths.

While everyone should be able to read code, writing good software is hard, and needs people who are dedicated to improving software development.http://www.wired.com/insights/2015/02/should-we-really-try-to-teach-everyone-to-code/

But...

Even weak programmers can make a good living in the United States. - Forbes

https://www.forbes.com/sites/quora/2012/06/21/why-is-being-a-programmer-a-good-career-choice/

Do you like mathematics or science?

Then Besut Kode & CGI is for you.

Google Code-in (GCI)

Google Code-in is extreme programming.

Six weeks (December January)

Many open source projects

Thousands of 13-17 year old, across the globe

Tasks of varying difficulty and typeCoding

Documentation/Training, including creating videos

Outreach/Research

Quality Assurance (testing)

User Interface

Wikimedia has participated since 2013

Wikimedia includes hundreds of projects, but is premoninately Php and Python. I organise the Python component of Wikimedia.

Google Code-in (GCI) outcomes

GCI participants are challenged every day, from the best mentors, and learn _a lot_ if they stick with the program until the end.

https://www.mediawiki.org/wiki/Google_Code-in_2015#Wrap-up_blog_posts

Participants get better each year they are involved.

GCI winners go to Google Plex, meet other winners and meet the mentors.

Github your portfolio

Who are you, really??

Most importantly, GCI participants build their online portfolio on Github.

Github has more than 14 million users and more than 35 million repositories. 125,000 LOC added per day.

It the largest host of source code in the world.

It also host websites.

Github is the 61st most visited site on the Internet.

Github your profile

But, Github is not a hosting company.

It is a social network and job recruitment company.

Your Github profile is your most important CV.It doesnt lie.

Github Archive

https://www.githubarchive.org/

And Github publishes their prime asset; thier metadata .

You can download it on Github Archive.

Github - statistics

And per city.

If you are a startup company in Surabuya, and you need a good developer, who are you going to call

Github Awards - yukiisbored

Git what is it

https://en.wikipedia.org/wiki/File:Git_operations.svg - GFDL (c) Duesentrieb

Github is website built around Git.Every programmer must know git.

Git is the canvas on which you work.

Git is an open source distributed version control system (VCS).

It manages files that are being edited by people all over the world, giving each copy its own version identifier. So each person knows which version they have, and how to merge their changes with other peoples changes, to the same file.

Git was created by Linus Torvalds, to help him build an operating system that you may have heard of, called Linux.

Git is replacing all other version control systems used previously.

Git what it is not

https://commons.wikimedia.org/wiki/File:Port_of_Shanghai,_2004.jpg CC-BY (c) Tibor Vgh

Well, not all VCS are being replaced.

Git is not industrial quality.

Git what it is not

Git is not good at:

Binary files

Large files

Large repositories

Access control

Mecurial is also common, but has the same problems above. Try it on https://bitbucket.org

Perforce is the answer for the above problems.

There are some weaknesses in Git.

The only other common open source DVCS is mecurial, and most developers are migrating from mecurial with git. If you want to try mecurial, create an account on Bit Bucket.

To solve the problems of git, use Perforce, but is not open source, and it is not cheap.

GCI winning tips

Be ready to start on Day 1.

Choose a project, now

Learn about the project, now

Become part of the project team, now

Read the GCI tasks before Day 1

Or ... write your own GCI tasks! ... now

GCI choose a project

Find a project that best suits you

You will do it for 6 weeks non-stop.

Choose something that is fun!

Find a project that best suits you.Either something you are good at, or something you are excited about learning.

There is a possibility that your first choice isnt part of GCI 2016.

So, pick a second/fallback project, just in case.

Check their GCI tasks from previous years, to ensure the tasks in GCI are what you want to work on.

You can write up GCI tasks, which will help the project become eligible for the next GCI.

GCI starting on Day 1

Install all of the tools

Be familiar with their coding guidelines

Watch them work

To really start on Day 1, you need to be prepared before Day 1

People participating in GCI for their second year, are already prepared. You can be too.

Install and use all of the tools

Be familiar with their coding guidelines

Watch their code reviewsSometimes parts of their coding guidelines are not formally written down *anywhere*, but are communicated during code reviews.

Understand which problems are HARD. Some of the GCI tasks may be labelled easy, but intersect with unsolved HARD problems, and youll waste a lot of time on the task.

If you were prepared, your first task will be approved immediately

GCI become part of the team

Learn how they communicate

Dont worry about your bad English

Dont use Sir

Learn who are the most helpful mentors

Become part of the project team, today.

Join their live discussions. Typically IRC.

Today.

During GCI, check in every day.

If you have prepared, you will be more advanced than other GCI participants. Help them.

Your mentor will love you!

GCI practise communicating

No more Sir!

When you are part of a group working closely together, informal English is used to communicate.

Learn appropriate communication in software projects.

Dont use "Sir" !

If you commit good code, and you will, you are not lower value than the mentor.

When you are part of a group working closely together, informal English is used to communicate.

Dont be shy of your English skills. Dont let it stop you from getting help.

Open source projects have many people where English is their second language, just like you.

Dont say sorry for my bad English every sentence.They know your English is bad. They only care about your code.

Static analysis
programming languages

How can I do all of these things, today

The easiest approach is carefully cleaning existing code.

Lint is the rubbish that sticks on clothing.Lint is also the bad code that sticks to good code.

De-linting, if done carefully, can provide endless number of tasksthat do not involve changing functionality, or require understanding the code.It allows you to be productive while familiarising yourself with the code.

https://github.com/mcandre/lintershttps://github.com/mre/awesome-static-analysis

Build and use new linting tools. They improve your understanding of the language itself,and common problems with using the language and its standard libraries.

Misspellings are another easy way to contribute to a project.

In this image, the Spanish word -- Gua - has a grave accent on the "i", which does not exist in Spanish. Immediately obvious to the Spanish.

Misspellings are a very hard problem to solve beyond simple cases like incorrect glyphs.

Practise using tools to identify misspellings.

http://jwilk.net/software/mwichttps://pypi.python.org/pypi/misspellingshttps://github.com/mcandre/aspelllint

Improve misspellings tools.

Also be familiar with grammar checkers.

Loklak - Challenge 2

A private repository will be created, and all participants who have finished Challenge 1 will have access.

1. Create five new "GCI sized" task/issues in the Besut Kode loklak repository.The mentors will mark them as easy, medium or hard

2. Solve issues created by someone else. To pass this challenge you must solve one medium or hard difficulty task, or three easy tasks.

Warning: DO NOT COMMUNICATE with the loklak project during Challenge 2. Besut Kode participants who successfully finish Challenge 2 will be mentored on how to interact publicly with loklak project.

Note: a more formal description of Challenge 2 will be provided before you when Challenge 2 starts.

Challenge 2 example tasks

https://github.com/loklak/loklak_api_go

It has a .travis.yml, but does not have Go linting.Create a task to implement Go linting, suggesting the linter to use.

Another participant can then solve the task.
