Recruiting 101 instead of 404 #

Thayer Prime says:

Recruitment is one of the hardest problems in scaling your tech company. Everyone wants the best, everyone wants diversity in hires, everyone wants the most affordable people - but companies rarely have the time, money or ability to invest in creating a world class recruiting team. So what are some of the common questions we can review, and how do you navigate the pitfalls of bad hiring as a starter for ten? Come and find out from an LRUG community Q&A to address some of the most commonly asked questions, and get some starter tips on hiring humans, not resources.

Your Qs will be A'd by Thayer Prime, of Team Prime who started life in the tech industry as a programmer twenty years ago, before turning to the dark arts of recruitment. She's been lucky enough to work with the likes of Sir Tim Berners-Lee, Jimmy Wales, Apple, Stripe and NASA to name just a few. She has founded three successful companies herself, and often acts as a strategic adviser to founders and C-level executives growing their tech capacity within their organisations.

For info on how to submit questions for the talk check out Thayer's email to the mailing list explaining the situation.

Afterwards #

We're all at home so there's no post-meeting pub meetup, however a few attendees often hang around on in the zoom call after the talks are over. It's a pale-shadow of the pub meetup, so if you have some ideas about doing something better do get in touch at organisers@lrug.org.

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 we are all in our own little bubbles.

Create a Twitter clone in 15 minutes in pure Ruby with Matestack #

Jonas Jabari says:

Matestack enables you to implement reactive web UIs in pure Ruby, skipping ERB, HTML and JavaScript. In a live coding session, we will create a Twitter clone using Matestack's core features from scratch!

Afterwards #

For the good of the country, we have had to pause our normal post-LRUG pub time, but typically a few folks will hang on in the zoom call after the talks are over. We've been meaning to try the new self-selecting breakout rooms too, which we could. But in general, the ongoing-pandemic after-meet experience could still use some work: if you have any ideas on that, do get in touch at organisers@lrug.org.

Patches Welcome! #

Everybody at LRUG probably uses open source software - unless they got lost on the way to another meeting - but it often surprises me how few developers take the extra step from using it, to contributing to (or releasing their own) open source software projects. I'm going to talk about how I got involved in the open source community, why I stay involved, and about my current open source projects

Denny de la Haye has been a programmer for nearly 30 years now - "although my ZX81 code is thankfully all lost in the mists of time (AKA audio cassettes and thermal printer paper)", he says. He has spent most of the last 4+ years writing Ruby, and most of the 15+ before that writing Perl. The switch between the two was less traumatic than he expected, but it did lead to starting another open source software project last year…

Convention over Kubernetes: (Almost) Configless Deploys with Kuby #

Rails' most well-known mantra is "convention over configuration," i.e. sane defaults that limit the cognitive overhead of application development. It's easy to learn and easy to build with. The development experience is fantastic… right up until the point you want to deploy your app to production. It's at that point that the hand-holding stops.

Heroku to the rescue, right? Just push your git repo to "heroku master" and never think about deployment again! Heroku is a great option for many small projects and the ease of deployment is exactly the kind of experience Rails developers are used to. To quote Aaron Patterson: "but at what cost?" You're tied to Heroku's stack and stuck within the limitations of their free tier. Heroku's add-ons can get pretty expensive too if you decide to upgrade later on.

How can we, but humble Rails devs, achieve the same seamless, turnkey deployment experience affordably? Enter the Kuby gem, a convention-over-configuration approach to deploying Rails apps using industry-leading technologies. Come learn how, with almost no configuration, you too can use Kuby to leverage Docker and Kubernetes to deploy your Rails app cost-effectively on a variety of cloud platforms.

Cameron Dutro currently works on the Quip team at Salesforce. He's been programming in Ruby and using Rails for ten years and has held previous positions at Fluther, Twitter, and Lumos Labs. When he's not reading about, using, or working on technology, Cameron can be found hiking in the hills behind his house or hanging out at home with his wife, daughter, and cat.

JWTs - what Rails developers need to know #

Dan Moore:

What is a JSON Web Token (JWT) and why do you care? JWTs are a stateless, standardized way to represent user data. This talk will discuss why JWTs matter and the nuts and bolts of JWTs. We’ll also discuss how you might use a JWT in your Rails or Ruby application.

Getting Past the Tech Test #

Michael Mazour:

Sometimes people have great backgrounds and great skills, but have trouble getting hired because they didn't approach the tech test the way the company wanted. As someone who reviews a lot of tech tests at work, I'm going to explain some of the unwritten rules and expectations that you might not know if you've been out of circulation or are just entering the job market, and help you level up your tech test game.

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?

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).

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.

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.

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.
