Pattern matching syntax was added to Ruby, in experimental form, in version 2.7. This talk will look at what it is, how we can use it, and where it fits in with existing Ruby control flow.
The syntax offers some useful ways to express control flow in places where we might have previously nested if statements or had to destructure data from complex objects.
We will also look at how pattern matching has developed in other languages, and find some good examples of using it in real production code.
Following our tradition for a meal in December, and given we like trying out new places, we've landed on Domo Restaurant this year in stylish Little Kelham.

We'll be around from 6.15pm and we've booked a table, so if you're planning to join us, please RSVP for us to confirm the table.
On behalf of Sheffield Ruby organising team, we hope you have a lovely break over the Christmas period and have a happy New Year.
About our talk
Performance problems got you down? Do memory leaks strike fear in your heart?
In this session I’ll share two real world stories of how you can solve performance problems and plug memory leaks. You’ll learn how to use tools such as ruby-prof and stackprof, interpret their output and gain extra insight into how your code is performing.
When dealing with memory leaks, the biggest challenge can be finding them. You’ll learn how to use rbtrace and ObjectSpace to identify what objects are being leaked and by which code, so that you can approach leaks with confidence.
About our speaker
Frederick Cheung started deep in the bit mines, programming in C, but picked up Ruby in 2006 and hasn’t looked back since. He’s the CTO at Dressipi where he likes to think about recommender systems, infrastructure and web applications.
Bonus - guest speaker and talk
Unfortunately, this has had to be postponed until the New Year - we'll be announcing more details soon!

About the talk
Mentoring and coaching, what's in it for me?
Mentoring and coaching techniques help people learn, focus, define and achieve their goals. That's all well and good... but why would you choose to be a mentor?
In this guided discussion we'll talk about the value of mentoring and coaching for the mentor, when to start, opportunities to get involved, and considerations from a contracting & consulting perspective.

About the talk
The life-changing opportunity to leave prison as a Software Developer
The general consensus is that prison is a bad place full of bad people. The first part of the statement is largely true, the latter somewhat of a misconception.
Prison is a bad place full of deprived people. There are very few opportunities for the average prisoner to turn their life around and a necessity for our prison system and prison education programs to address this problem. Being in desirable employment is all it will take for a large percentage of our 83,000 prisoners to stop reoffending.
This talk is about something which actually has the potential to make a difference to two socio-economic problems in the UK; the rate of reoffending prisoners and the inadequate supply of software developers.
Code 4000 is a prison-based program which equips inmates with the necessary opportunities to be released into quality employment within the tech industry.
About our speaker
Josh Rolland is a former prisoner who while in custody engaged in an initiative which teaches inmates to code; Code 4000.
As a result of his hard work and competence, the scheme was able to look for employment opportunities for Josh ahead of his release. This has led to Josh starting work as a Junior Java Developer at Metro Bank in Central London exactly one week after being released from prison earlier this year.
Because of his back story, he is very aware of the potential for tech talent to be found from all walks of life and with a range of backgrounds. As well as the talent in general which exists within the UK prison system. Josh wants to make people aware of the positive impact of Code 4000 in order to generate new stakeholders and employment opportunities for other ex-prisoners going forward.
As a bonus, we have the opportunity to have Ryan, Josh's mentor/coach, as a guest speaker to share his side of the story, too.

It's time for our summer social, and as mentioned previously on the 3rd Wednesday of the month!
We're checking out [Kommune](http://kommune.co.uk/) from 6.15pm to prolong the summer a bit more. We don't need to book this venue, as given it's size, we should be ok. We'll tweet out the table number when we are there, though!
Looking forward to seeing as many #shruggers as we can!
Acceptance and unit tests will help you to deliver working software and guard it against regressing into a complete mess.
What is not guaranteed is that the code will remain performant. Without performance tests, it’s easy to refactor your way into slow code.
Let’s see how we can change this!

In one timeline a quick path to clarity. In the other a painful journey trying to uncover the obscure intent of a line of code. The only difference between these two realities? The revision history…
This is a story about revision histories and their impact on software maintainability. Think Sliding Doors, but with more Git!

Measuring Chronic Pain Outcomes with Ruby and Twilio
Description changed:
We can use our skills to improve the lives of those around us, not just our employers and customers. In 2017 Nick's fiancée's surgeon told her that she would require a hip replacement. The surgeon remarked that barometric pressure very much affected day to day chronic pain. He decided to test this.
Using a Twilio SMS 'front end', Ruby on Rails 'back end', and WeatherUnderground integration Nick promptly built an application to randomly request her pain levels against local barometric pressure for four months and processed the results. The processing involved his first foray into machine learning concepts with Ruby. This talk will tell their story, walk through the exact code as it was executed, and elaborate on our responsibility to 'give back' to those around us with our Ruby 'superpower'.
About our speaker
