Giving quick intro on functional programming on Lambda Jakarta October 2015 Meetup

Hi guys!

Now it’s community time! To be specific, Lambda Jakarta meetup time!

This time (as suggested on previous meetup, on my blog, and on Lambda Jakarta’s Slack group) Erik Dominicus and I are going to give separate presentations on the same topic: introduction to functional programming language.

The place was still the same, MNC building, but the date was 31st October, 2015 on 12.30 PM (after lunch).

Yes, we both deliver the same concept but we decided to give different ways to deliver these presentations.

I focused on giving intro with the past background of common non functional programming introductions including OOP (hence imperative), and then gently driving the mindset into functional. Eric focused on giving intro directly on conceptual principles on functional programming.

The invitation page on Lambda Jakarta’s meetup of October 2015 page neatly described this:

Yes, I focused on gentle intro with introduction from non functional programming.

Introduction to functional programming will be delivered and presented as gentle intro into the concept regardless of functional programming languages (language agnostic). This quick intro will get you jumpstart with relevance to other todays programming paradigm such as OOP and imperative without hurting your brain

This is the excerpt from my slides:

..and we all know these facts:

Yes, functional programming should be fun! Unfortunately, I didn’t have the chance to be captured as video. The next meetup will try to repeat my talk and it’ll be video captured

These are the pictures:

..and there’s more on Lambda Jakarta’s meetup page for October 2015

I was so excited to have many feedbacks and questions in the middle of my talk! One of them was asking about asynchrony and synchrony concept. Although they are concerned and closely related to parallel programming, asynchrony and synchrony are not parallel programming concept. Asynchrony, synchrony are just part of concurrent programming, and parallel programming also part of concurrent programming.

This is also unfortunate consequence of common fresh graduate of computer science faculty in Indonesia: the curriculum keep mixing wrong concepts, and always leaning more on “industrial trend” based on not so official TIOBE index.

Very well, this is our responsibility to change this, right?

We have agreed to have next meetup soon after the TechinAsia event (11th November). Stay tuned on Lambda Jakarta’s meetup and Slack website!

Attending Lambda Jakarta September 2015 meetup

Hi guys!

In this blog entry, this is my story about helping to organize meetup of Lambda Jakarta.

The meetup was held on 19th September at MD Entertainment Tower 2.

The link is: http://www.meetup.com/Lambda-Jakarta/events/225037500/

The place of this meetup look weird, it looks like a building with lots of venous blood pumping;

The agenda is:

• Presentations from Erik Dominicus and Dicky Arinal
• General functional discussion,
• Meetup formalization and next steps

Presentations from Erik Dominicus was quite great. He presented a quick intro to Haskell, a quite old functional programming language that still influences many functional programming language today including ML, F#, Scala.

Dicky Arinal presented a lightning intro to concurrency in networking. A quite tedious and technical talk, but quite refreshing to know deep into what’s going on at multithreading in networking world.

The formalization was originally to discuss what will be the next meetup, but then the discussion crystalized onto one need of having online collaboration. After brainstorming, I proposed to use Github and Gitter to have chat. But most of the audiences were familiar with Slack, so I decided to jump in and set up Slack:

The Lambda’s Slack link: https://lambda-jakarta.slack.com/messages/general/

The collaboration is nice, you should try it! It’s quite the same as Gitter, but unfortunately not all of us can directly join the confirmation, you have to be invited first.

Here is the conversation at #general channel:

Now we have more channels for specific interests:

Of course, there’s F# in #fsharp channel

Now the organization of Lambda Jakarta has been set up as a repo in Github! <link is: https://github.com/Lambda-Jakarta >

Go Github! At the picture above, I also set up a repo to contain all of the source code sample to teach functional programming. This meetup was fun!

This the shoot from the meetup:

The next meetup has been also scheduled for 31st October 2015. Guess what? I’ll present an intro to Functional Programming without hurting your brain, and Erik will present an intro to Functional Programming but with totally noob view!
