August 2015 Meeting

Hosted By

Skills Matter

Thanks!

The August 2015 meeting of LRUG will be on Monday the 10th of August, from 6:00pm to 8:00pm (talks start at 6:30pm).

Venue change!

We're back with our usual hosts, Skills Matter, but it's in their new Code Node venue between Moorgate and Liverpool St. stations. Full venue and registration details are given below.

Agenda

Hello, declarative world

Tom Stuart says:

Ruby’s billed as a “multi-paradigm” language, but, let’s face it, we use it to write imperative object-oriented programs. I'm interested in different ways of programming computers, because I reckon imperative programs are far too low-level and overspecified, which is why as a species we're generally terrible at writing them. In this talk I want to encourage you to think outside of your normal programming habits; I’ll present a more abstract and declarative style called relational programming, and show you how to implement a minimal relational language in Ruby. (Dog whistle: this is μkanren.)

Domain Driven Design, In the Wild

Chris Patuzzo says:

Every day, we write software that solves business problems. How we actually do that is largely up to us. We tend to build models that encapsulate complexity and provide abstractions that help us reason about the problems we solve.

We stress our models with incremental development. Changing business requirements challenge the durability of our models. The magnitude of change is an indicator for the effectiveness of our models' ability to represent the problem domain.

At Which? we used Domain Driven Design to deliver our most recent project. In this talk, I will share those insights. I aim to cut through the jargon and give concrete, real-world examples of how we applied the principles of DDD to build a product that anticipates change.

Pub

The talks will end at 8pm and we'll head to a local pub. As it's a new venue we don't know which one yet. Watch this space if you can't make the talks but want to join us afterwards.

July 2015 Meeting

Hosted By

Overleaf Altmetric

Thanks!

The July 2015 meeting of LRUG will be on Monday the 13th of July, from 6:00pm to 8:00pm (talks start at 6:30pm).

Host & venue change!

Our usual hosts are unavailable for this meeting. Thankfully Overleaf and Altmetric stepped forward to host us in a venue in their office complex.

This venue has strict 100 person capacity and we require attendees to register in advance (for free). Full venue and registration details are given below.

Agenda

LEARNING HOW TO LEARN RUBY (and rails, and sinatra, and …)

Sam Joseph says:

At Makers Academy we coach students through the process of learning Ruby, Sinatra, Rails, JavaScript, JQuery and Angular over the course of 12 weeks. Students range in age from 18 to 60, although the majority are in their late 20s or early 30s, already have university degrees (often a humanities subject) and have spent 5+ years in the workplace doing sales, marketing, design, management or some other relatively non-technical role. The majority of students have also had almost no programming experience prior to their preparation for the interview and selection process that they must go through to get on the course. In this talk I will explore what makes a 12 week intensive bootcamp tick, and the particular challenges the students face with learning Ruby and JavaScript.

Flaky tests & Capybara best practices

Karlotcha Hoa says:

One of the main purposes of testing is to enable us to trust the performance of our code in an automated way. Unfortunately, several problems often arise with automated tests. One common and particularly annoying problem that we began experiencing in our codebase was flakiness.

In this talk, I will discuss common problems that may cause this issue, and some solutions we discovered based on our own experience at SimplyBusiness.

Pub

The talks will end at 8pm and we'll head to The Fellow shortly after. We've reserved the entire first floor, so if you can't make the talks but want to hang out with some rubyists afterwards, head on over and climb the stairs to say "hi".

Agenda

Redis is the answer, what's the question?

Garry Shutler says:

There are very few things that are part of my go-to toolbox, but Redis is one of those things. I don't think there's a better, more flexible piece of infrastructure you can have at your disposal.

I'll cover the very basics of using Redis and general patterns that you can use within your own systems. I'll also share some concrete examples of what we've used it for at Cronofy.

Ruby Magic

As a child, Andrew McDonough loved magic. One of the best Christmas presents he ever received was a magic set. As an adult, Andrew prefers to perform magic using Ruby. In this talk, he will attempt an array of traditional magic tricks, using only IRB.

Test Bisection with RSpec

Simon Coffey says:

I'll talk about a useful technique for debugging order-dependent test failures, and introduce an upcoming feature in RSpec that automates it.

Pub

All those talks will take us to about 8pm, after which we leave Skills Matter's offices and head over to The Slaughtered Lamb to continue the meeting. While we ask you to register for the talks, there's no need to do so for this pub part; feel free to turn up even if you don't make it for the talks.

Agenda

Rewriting Code and Culture

Sabrina Leandro says:

This is the story of a company that survived a much needed transformation of its product and codebase, but most importantly, of its culture. There's no real prescription for being agile. It's about the journey a team takes to discover how to best work together and deliver great products.

In this presentation, I'll share a candid view of a team trying to overcome a slow product development process. How we refactored our way out of badly coupled code, moved to continuous deployment, and greatly improved our approach to product and software development.

Rails New Way

Kamil Lelonek is going to talk about building modern, maintainable and robust Rails applications. He asks:

  • Why a conventional Rails architecture fails?
  • What price do we pay for Rails’ simplicity?
  • Why Rails tries to solve complex problems in one monolithic class?
  • Should we follow the Rails way or drop Rails at all?

With presented building blocks he'll try to help solve common problems in current Rails applications.

Book Giveaway

Infinitium Global

The nice people at Infinitium Global have arranged to make 20 copies of David A. Black's "The Well Grounded Rubyist 2nd Edition" available to LRUG members and we'll be handing them out at this meeting. We used our mailing list to allocate each book to a lucky LRUG member on a first-come, first-served basis. Infinitium are hoping to make this a regular event, so if you'd like to be in with a chance of getting your hands on a book in the future you should sign up to our mailing list.

Pub

Our talks usually end at about 8pm after which many members can be found at The Slaughtered Lamb chatting about what they just learned and other goings-on in the ruby world. The pub is large and has a good menu of food and drinks (alcoholic and non) so all are welcome, even if you were unable to attend the talks.

Agenda

Un-artificial Intelligence: How People Learn

Melinda Seckington says:

Most developers are familiar with the basics of AI: how do you make a computer, an algorithm, a system learn something? What most don't realize though is that the same principles are applied to people. This talk looks at the theory behind how people learn, and maps it to real life examples of how specifically developers learn.

The shiny new mongo gem

Emily Stolfo is visiting from Berlin to tell us all about writing the new ruby driver for MongoDB:

The Ruby team at MongoDB spent the last year building a new driver – the mongo gem – that was released a few weeks ago. Emily is going to talk about how they built the driver, its design, and why its availability is so exciting for the Rails and Ruby community.

For reference, an article announcing the release: shar.es/1g0PFK

MongoDB 3.0 was also released a few weeks ago and she'll talk a bit about what makes this version so monumental and why you should try it out.

Pub

The formal talks-and-speakers-based part of the meeting ends around 8pm, after which we make the short trip to The Slaughtered Lamb to continue the event. Most of the attendees and speakers are usually here so it's a great chance to find out what's going on in the LRUG community, or to catch up with or make some new friends. Attendance of the talks is not a prerequisite for coming to the pub, so please do come along!

Agenda

Exploring #to_proc

Paul Mucur says:

A look at how some "odd syntax" introduced in Rails 1.1 and then added to Ruby itself might not solely be for the sake of convenience but hint at a more powerful idea seen in other programming languages.

pkgr - Packaging Ruby applications with no sweat

Łukasz Korecki says:

In the life of every* project there is this moment where standard deployment methods just don’t cut it. You have many servers, many applications, many developers. It can become a mess very, very quickly.

Have you ever dreamed of hosting your own apt repository? When was the last time you were annoyed about slow deployment times because the asset pipeline needs to run every single server your app runs on? Oh and lets not mention installing ruby version managers on servers, ok? (I will though).

In this talk I will show how packaging (and deploying) Ruby applications doesn’t have to be hard or time consuming and can work with a project of any size.

* - huge assumption warning!”

Pizza

Braintree Payments

The nice people at Braintree Payments have arranged to buy some pizza for us to eat during the talks. The Pizza will be there from about 6pm so turn up early if you're hungry! There'll be a selection to suit most tastes: meat-eaters, vegetarian, and vegan. We're not sure if the pizza company does a gluten-free option, but we'll get one if they do.

Thanks Braintree!

Pub

The talks end at 8pm and I'm sure all that talking and pizza will have given us a bit of a thirst. The evening continues at The Slaughtered Lamb which is a 5 minute walk from the Skills Matter office. It's a great opportunity to talk to the speakers in question, or just catch up with some other London rubyists. If you're unable to attend the talks please feel free to attend the pub only.

Bath Ruby Conf tickets giveaway

Team Prime

Bath Ruby Conference 2015

Thanks to the nice folks at Team Prime and Bath Ruby we are able to provide 4 people with free tickets and a £70 allowance (enough to cover return train travel from London). The tickets are available to LRUG members that wouldn't otherwise be able to attend. The deadline to put your name forward for a ticket is midnight on Sunday 8th, February 2014. If more than 4 people request the tickets a draw will be held privately to select the winners. The recipients of the tickets will not be publicly announced, but we'll thank Team Prime and the Bath Ruby Conf organisers at the start of the meeting.

Pub

All those talks are bound to generate some thoughts we'd like to discuss afterwards. So we cross Goswell Road and head down to The Slaughtered Lamb to have those discussions in a more informal setting. If you didn't make it for the talks then do feel free to turn up just for this bit.

Agenda

Who’s afraid of database views?

Robbie Clutton isn't, that's for sure:

Many Rails codebases I look at work hard to put all logic into the application source code, using the database only a dumb store. But, there are circumstances where it makes sense to leverage features of a database and in this talk I'll cover one of those features in Views. I'll walk through examples of why you might want logic in two places, how views compare to caching for performance considerations, using views as a facade on legacy tables and how to test views alongside your application.

PeerConnect all the things

Tom Cartwright says:

WebRTC is an exciting technology currently in, or coming soon to a browser near you. In this talk I will explain what it is, how it works and how to setup some ruby services to support a WebRTC-based application.

Telling stories through your commits

Joel Chippindale has a story to tell:

In this talk we'll look at some of the ways that you can improve how you develop code and communicate with your team through your commits.

Pub

After the speakers are done it's time for the rest of us to give our vocal chords a workout. We have to leave Skills Matter by 8pm so we head to The Slaughtered Lamb to do so. If you can't make the talks then do feel free to attend this part. There's no need to register for this bit though, so just turn up!

Are you sure it's right?

Owen Ben Davies wants us to think about what is and what isn't right with our software:

This talk on both Rails and plain Ruby apps will cover

  • Testing
  • Code standards tools
  • Validations and verifications
  • Security tools and frameworks

An RSpec 3 Talk

Sam Phippen says:

RSpec 3 is the recently released new major version of RSpec. It contains a host of new features, and has removed or altered many old ones. In this talk we’ll cover the most significant changes that were made in RSpec 3, the upgrade path between RSpec 2 and 3 and some of the common pitfalls that you might fall into when using this new major version of RSpec.

Pub

That all sounds super-interesting and we'll want to talk it all over together, but we have to be out of Skills Matter by 8pm. Don't worry though, that doesn't mean the evening is over! The Slaughtered Lamb is a short walk away and has plenty of space for us to have those discussions. No need to register for this bit, if you can't make the talks do feel free to turn up just for the socialising afterwards.

Agenda

Julia - Fast and Dynamic

Avik Sengupta wants to introduce us to a new language called Julia:

Can a programming language be fast yet highly dynamic? The creators of Julia, a new language with a numeric focus intends to answer yes.

In this talk we will introduce the language, and discuss some of its design and implementation decisions that make it particularly amenable to generating efficient machine code. We will also talk about Julia's impressive language interop features, and see examples of calling Ruby code from within Julia.

Peas - A Docker and Ruby based PaaS

Thomas Buckley-Houston says:

I'll be looking at the basic technical concepts of the Platform As A Service paradigm (eg; Heroku) and what Docker and Ruby can contribute to it. Some of the highlights will be; using Docker inside Docker, how to test this complex stack and concurrency using the Celluloid gem.

Pub

After the talks are finished we leave Skills Matter and move to The Slaughtered Lamb to continue the evening. We finish the talks at about 8pm, so if you only want to attend this informal part aim to be at the pub by about 8:10 and you should be just in time to fight with us for room at the bar.
