Wizards without magic #

Duncan Brown:

Multi-step forms (a.k.a wizards) are fiddly to build and difficult to test. (And not just in Rails). Why is that, and how can we make them better?

Afterwards #

It's not quite hanging our of drinks and food in a local pub, but a few of us usally hang out in the Zoom chat after the meeting to chat. It only really works with a handful of people though, so we're still on the lookout for something else tha would work for more attendees. If you have any ideas on that, do get in touch at organisers@lrug.org and we can explore it together.

Language doesn't matter: what makes a senior engineer? #

Matt Bee:

What makes a senior engineer? What other aspects of being a senior engineer are as important, if not more important, than knowing a programming language inside out. What things can you work on to become or be a better senior engineer (that won't have a new framework out by next week!). This is a set of lessons learned in a journey from self taught front end developer to senior polyglot developer (via ruby).

1. LRUG August 2020 - Matt Bee - Language doesn't matter/ what makes a senior engineer?

Doing the right thing #

Chris Zetter:

Ethics are the principles of right and wrong that govern our behaviour. Using examples from my experience, i'll share some tools that you can use to understand ethical decisions and ways to help ourselves and our team make the right choices.

Improved security for password authentication #

Jolyon Pawlyn:

Devise is a great authentication solution and is standard in many Rails applications. I want to look at 2 easy improvements to the default password validation. Then let's see what it takes to implement bare bones two-factor authentication using Devise and Warden.

The security features to be covered can be viewed in an example application.

Jolyon is a volunteer at Crowdfrica, ex Contentful, Wunder Mobility and Unboxed Consulting, and also an aspiring yardener.

Perfect is the enemy of good #

Nicky Thompson:

This talk is a rambling rag-tag collection of software engineering and problem-solving lessons learned over the course of mumble years as a developer and now an engineering manager. It includes practical tips, philosophical insights, or just advice that other people gave me that I found helpful. These ideas have helped me be better at my job over the years. They are tried and tested, things that I have actually done throughout my career. They might or might not help you.

Nicky is an Engineering Manager at FutureLearn, providing management and support to the Technology Team. Offline, Nicky enjoys watching bad TV and learning new stuff: this year it's a serious sewing/dressmaking habit.

…. you? #

As I mentioned above, we've basically run out of offers to give talks. I can certainly vamp for ten minutes about whether or not I care about using single or double quotes for strings without any interpolation, but I think it's almost certain that some of you have some thoughts or experiences that might be more interesting.

Please get in touch on talks@lrug.org and we will take it from there.

RubyConfBY Raffle #

The kind folks at RubyConfBY have given us two tickets to their conference to raffle to our attendess. The conference is going to be held (online) on the 18th & 19th of July, between 2-6PM CET (so that's 1-5PM BST). They've got a great line up of very interesting talks, and of course, it's never been easy or cheaper to attend a conference since there's no travel or hotel costs to factor in. But you can reduce that cost to zero by signing up to attend LRUG.

During the meeting, we'll run a raffle for all registered attendees and pick two. And even if you don't win in the raffle, the organisers have arranged a discount for LRUG members, which we'll share on the night.

Afterwards #

Normally a few of us hang around in the Zoom chat after the meeting, but we're still on the lookout for other things we might try. If you've got a good idea of how to replicate the post-talk chats get in touch at organisers@lrug.org and we'll see what we can do.

Hanami, another Opinionated Rack-based Framework #

Panos Matsinopoulos:

We present Hanami and its differences to Rails. Then we show an integration case between a Hanami and a Rails project. Finally, we close with a PR on the Hanami project.

Panos is a Senior Software Engineer at Lavanda.

Agile or Waterfall; a risk management perspective #

Alfredo Motta:

Today Agile is the default choice for software development out there. Every conference, book, or blog post is telling us we are doomed to fail if we don’t follow this established convention. But isn't it surprising to think that Agile is advocated as the right methodology for every possible company doing software out there? Are we going to organize software development exactly the same way if we are working for a startup, NASA, or FedEx? It seems hard to believe. In this presentation, I will explore the mental model to help you choose when you should (or sometimes should not) use Agile using the lenses of risk management. My goal is to provide guidance for the puzzled business owner, project manager, or software developer who wants to pick what's right for their company or team.

Comparing the speed and elegance of different computer languages using a Hamiltonian curve algorithm as the comparator #

Peter Bell:

My company (Trapeze) specialises in public transport including schedule optimisation. Finding Hamiltonian curves is a sub-problem to the travelling salesman problem and of the general problem of optimising pickup and drop-offs in demand responsive public transport. This talk will compare implementing a Hamiltonian curve finder in a number of different languages. The talk looks both at the speed of the language and the elegance. For Ruby, I compare a couple of different implementations. Other languages that are compared are Elixir, Go, Javascript, Java, C++, C# and Python.

The source code is in a public Github repository details of which I will provide as part of my talk

Debugging Ruby HTTP Library Surprises #

Sam Joseph:

Some folks prefer 'puts' to debugging with something like pry-byebug, but I'm a huge fan of debuggers, particularly stepping through my own code and the code of the many libraries we all rely on. In combination with bundle open to insert breakpoints into the code of gems being used in your stack, debugging can expose really tricky dependency bugs, as I aim to demonstrate with one that I found in the way different ruby HTTP libraries can interact.

April 2020 Meeting

The April 2020 meeting of LRUG will be on Monday the 6th of April, from 6:20pm to 8:00pm (meeting starts at 6:30pm). The venue this month is provided by…

vmmmmwwemmwmmmph

PhysicalProximityError: meetings of > 2 people are currently forbidden

That's right folks – while we all collectively do our part to battle COVID-19, LRUG too must adapt for this brave new world of staying the hell indoors.

The good news is that we've done some testing and we think we can hold a decent version of LRUG online, from the safety of our own respective homes. The very kind folks at Cleo have loaned us their generously-appointed Zoom account and we're going to try running the meeting using that this month. There are likely to still be a few rough edges while we learn to translate our super-polished absolutely-no-faffing-around-ever-with-laptops-and-projectors high-production-value process into this new medium, but we will get there in the end.

Full registration details are given below. We will only be sending out joining details to people who have registered, so please do make sure you do it.

Agenda #

Food & Drinks #

Hopefully you have some to hand. Or you could always nibble on that hoard of toilet paper? Anyway.

We've got two talks for you in April; we've got room for a third, and we desperately need more for the rest of year (cough talks@lrug.org cough), but anyway, where's what we've got so far:

How to take control of code quality #

Joel Chippindale:

We all know how valuable it is to keep the quality of your code high. Working on a high quality codebase is more enjoyable and enables us to deliver value much more effectively for our users and yet, time and again I hear engineers saying, “I am not allowed to spend sufficient time on code quality”.

This talk clarifies the value of maintaining a high quality codebase, gives you guidance on how to talk about this to help you get the support of your colleagues and managers for spending time on this and also outlines some key practices that will help you achieve this.

Music Experiments in Sonic Pi #

Rob McKinnon:

Let's celebrate Sonic Pi's v3.2 release, scheduled for 28 Feb! Sonic Pi's an open source Ruby code-based music creation and performance tool.

Rob's presenting a few experiments in Sonic Pi, covering oddities such as:

• negative melody
• Jianpu (numbered musical notation)
• just intonation
• microtonal music - 19 EDO (Equal Division of the Octave)
• interfacing with MIDI controllers over USB and bluetooth BLE.

Also Rob will walk us through a memory management improvement PR to Sonic Pi - that may have made it into the release.

Afterwards #

Afterwards… well, that's a good question. Obviously there's no pub, but we invite you instead to conjure up the image of a gently roaring fire, and perhaps to open a beer or other beverage while holding that image in your mind, and then think to yourself that it's really a wonder to be alive at all, even in strange times such as these, and really doesn't it demonstrate how much we all rely on each other, on our neighbours and colleagues and friends, and gosh darn it we shouldn't forget that when this is all over, that we truly do need each other, and we shouldn't take each other for granted, and dammit Billy I just gotta say it that I love you dude, I know I shoulda said it before all this, but I want to say it now so you know, you're a good friend Billy, you really are, and thanks for being there for me.

Or there's always telly.

Registration #

Prior to attending you should familiarise yourself with our README paying close attention to the code of conduct which applies to all attendees, even though there's no pub or venue. Basically they are good rules to generally live your life by.

Secure your place #

You can register to attend via eventbrite.

It's vital that you register because we will only be sending out the meeting connection details to those registered attendees. So keep your eyes peeled for an email in your inbox on the day.

Some of you may already be living your days in Zoom meetings but if not, and if you want a head start, you can make sure you have the Zoom client by visiting their download page.

So that's that. All that remains to be said is

I got an email from the Government the other day #

Stuart Harrison says:

Email has been around for a long time, predating even the Internet, and despite the best efforts of big tech to monopolise our communications, it's still the most popular way to for people to communicate online. This ubiquity means it's a really easy wayf or Government to keep in touch with us, but email is a tricky thing to manage, running mailservers can be a faff, and email as a service solutions can be expensive. In this talk I'll go through a potted history of email, talk about a tool that the Government Digital Service have developed to make email easier for goverment agencies, and a Ruby gem I've build to make it even easier for Rails devs.

My first Rails bug report #

Alex Balhatchet says:

Story time! Here's the bug I found, how we determined it was a bug in Rails 6, how we dealt with it including working around it and submitting the bug report, and finally getting to remove our workaround once the bug was fixed and the new Rails was installed :)

Tech for good with Ruby on Rails #

James Hand and Alan Bridger say:

Giki Social Enterprise uses Ruby on Rails to help people live sustainably. We'll talk about what we do and why Rails is such a good framework for helping people to make sustainable and healthy choices.

London Ruby Events #

Jairo Diaz says:

I am going to tell you about the Ruby events in London that I am organising such as the Ruby Hacknight and Ruby London Jobs and other events for the community that are the most common. I will also mention different event formats which I have experienced and found useful for different purposes.

Afterwards #

Designing Domain-Oriented Observability in your system #

Alfredo Motta says:

What does it mean to make a system observable? Too often this is translated into simply installing technical tools to measure low-level concerns like memory, CPU or background queues size. In this talk, I will present the concept of Domain-Oriented Observability, explore how it affects the cost of maintaining your system and finally show some of the tools and solutions that can help you put it into practice.

1. LRUG February 2020 - Alfredo Motta - Designing Domain-Oriented Observability in your system

Semantic Versioning, Ruby Versoning, and the forward march of progress #

1. LRUG February 2020 - Jon Rowe - Semantic Versioning, Ruby Versoning, and the forward march of progress

Influence your company beyond code #

Mugurel Chirica says:

It's important for all the engineers to realise that individually they are able to help shape a company's culture, tech excellence, and tech direction.

There are various ways to achieve this, in this talk I'll present some of the common options while focusing on creating communities of practice - groups of people that meet with a common goal in mind and relevant to the company's interest, both sponsored by leadership or started by engineers.

Ruby Talent Show #

This meeting is dedicated to all the things ruby can do that isn't just pulling data out of a database and rendering it on a website.

Ruby on the Big Screen #

Steve Butterworth says:

Using Ruby to crunch the numbers, read tv captions and drive a 30m long LED screens at The Open Golf Championships. A whistle stop tour of the setup, the architecture and the code that goes into making something like this work and what can go wrong!

Re-interpreting data #

Murray Steele says:

Some time ago I stumbled across the header description for WAV files and wondered, what if I took a file and calculated the appropriate WAV file header for it, could I hear my data? Yes, you can. You probably don't want to, but you can. You can do something similar with BMP and MIDI files too!

Ruby's a critic #

Nuno Silva says:

RubyCritic provides a report about code quality. You can run it locally to view how your project is doing and what are the smelly spots. A way of getting sense of how your code quality is evolving over time is by setting it up on your CI and storing the reports artefacts.

Getting started with mruby #

Fred Cheung says:

find out what mruby is, why you might want to use it and obstacles you might encounter along the way.

You? #

We’d like to hear from people using ruby for something that is a bit out of the ordinary. Mostly we’re probably all using ruby for building websites, or for devops, but that’s not all ruby can do.

Some examples:

• making music
• generating graphics
• interactive chatbots
• games
• etc…

So, what are you making ruby do that fits the bill? Or, what are you using ruby for that doesn’t fit that bill, but also isn’t a standard webapp? We'd love to hear about it, whatever it is. Show us what ruby can do!

Afterwards #

Our goal is to be finished exploring ruby's talents by 8pm, after which we'll move to a nearby pub to talk about the talents on show and do a spot of socialising. We'll take advice from GoCardless on which local pub will best accommodate us and keep you posted if we know in advance.

Of course, even though this is the socialising part and seems more informal, please remember that still we consider it to be a part of the meeting and covered by our code of conduct.
