Thanks!

The April 2014 meeting of LRUG will be on Monday the 14th of April, from 6:30pm to 8:00pm. Our hosts Skills Matter will be providing the space, at their offices on Goswell Road; The Skills Matter eXchange. Registration details are given below.

Agenda

Adventures in early-adoption of open-source code

Some of the team from the ODI want to present about their work:

Last year, the ODI found themselves wanting to use the code behind gov.uk for a new project. In this talk James and Sam from the ODI tech team will share their experience of picking up a codebase which was open source, but never really designed for reuse, and what they learned along the way.

Aspect-Oriented Programming in Ruby

Camille Baldock says:

Many of us developers love arguing about architecture that we dislike and refactoring our code to loosen coupling and weaken dependencies between our objects. Unfortunately, some overarching parts of our applications, like persistence, networking, notifications, logging, auditing, are scattered in our code, forcing us to specific explicit dependencies between them and our domain objects.

Aspect-oriented programming is a solution to the problem of some features affecting virtually all business requirements, and expresses that problem in a compact and DRY way.

In this practical talk, Camille will:

  • introduce the basic concepts of AOP, and how it is still relevant even in a non-statically typed language like Ruby
  • show you how to easily and quickly leverage some AOP principles in your Rails application
  • play with some AOP-friendly constructs in Ruby 2, in particular TracePoint
  • walk you through two existing Ruby frameworks to practice Aspect-Oriented Programming

She will even attempt to prove that not all things coming from the Java world are necessarily bad.

Pub

After the talks finish, usually 8pm, we decamp to The Slaughtered Lamb to finish up the evening. Although you have to register for the talks, the pub part is open to all. If you can’t make the talks feel free to turn up for this second half of the event.

Sponsored Drinks

Resource Guru

The nice folks at Resource Guru are buying us some drinks at the pub after the talks. That’s nice, isn’t it?

Registration  

To secure a place at the meeting you must register with our hosts Skills Matter. It helps to make sure we have the room laid out with enough chairs, and in extreme cases that we get priority on the larger rooms over other groups using the space on the same night. Also, it’s polite (don’t forget MINASWAN), so please do register with Skills Matter. Prior to attending you should familiarise yourself with our README.

You can also follow this meeting on lanyrd, but this is not a meaningful way to tell Skills Matter you wish to attend. It’s just for the lols, innit?

March 2014 Meeting

Skills Matter

Thanks!

The March 2014 meeting of LRUG will be on Monday the 10th of March, from 6:30pm to 8:00pm. Our hosts Skills Matter will be providing the space, at their offices on Goswell Road; The Skills Matter eXchange. Registration details are given below.

Agenda

Rage against the state machine

Andrew Appleton says:

A story about the problems we faced modelling state and recording state changes at GoCardless and how we generalised our solution to those problems into a new gem, Statesman.

Marketing for Developers

Derek Hill from eBench wants to talk to us about marketing:

I’m a relative newcomer to Ruby, but I’ve got lots of experience in marketing.

Over the last two years I’ve spoken to many experienced devs about their marketing challenges, and witnessed how simple marketing mistakes can derail a project.

In the consumer goods industry marketing is a discipline, with structured ways of working through it. I will demonstrate that this structure works well for tech startups, and give you a practical checklist you can apply.

Building a SOA network of daemons with Go, Ruby and ZMQ

Ismael Celis says:

I would like to talk about a series of custom-made infrastructure components that I’ve built over several months to support a hosted e-commerce app that I run in my spare time.

This consists of a central events hub written in Go, to which the user-facing apps send events, and a series of Go and Ruby scripts subscribing to said events on a ZMQ socket and doing varied things such as analytics, periodical backups and house-keeping.

The code I’ll show is mostly Go, with some Ruby to illustrate how this all hooks in to my Ruby apps and existing infrastructure. I’ll try to show why Go is great for writing small, focused scripts that support your user facing apps.

You can read a more detailed overview on a blog post he wrote about it a while ago.

Pub

Our talks usually end at 8pm, but that’s not when the evening ends. Most of the attendees head over to The Slaughtered Lamb to talk things over; the speakers are usually there too, so you can ask them about their talks if you didn’t get a chance during Q&A. The pub part of the evening open to all, so if you couldn’t make the talks, or just don’t fancy them, do turn up here!

Thanks!

The February 2014 meeting of LRUG will be on Monday the 10th of February, from 6:30pm to 8:00pm. Our hosts Skills Matter will be providing the space, at their offices on Goswell Road; The Skills Matter eXchange. It’s a great space with plenty of room for the group, but you still need to register to let Skills Matter know you are coming.

Agenda

Lightning talks!

February is our annual lightning talk evening and as usual we’re using the 20x20 format for the talks. If you’ve never encountered this format before it’s when the speaker has 20 slides that auto-transition after 20 seconds, giving them a total of 6 minutes and 40 seconds in which to get their point across.

Our volunteers for 2014 are:

Pub

Once we finish up with the talks we head over to The Slaughtered Lamb to continue the evening in more informal, if admittedly slightly noisier surroundings. If you can’t make it for the talks feel free to pop along to the pub for about 8pm, which is when we usually finish up.

ReThink Recruitment

The nice people at ReThink Recruitment are buying some drinks at the pub after the talks. Thanks!
