November 2019 Meeting

Change of venue!

We received the sad news today that Skills Matter has gone into administration and all meet-ups and conferences have been cancelled with immediate effect.

Thankfully our friends at the FT have stepped in last minute to provide a venue. Full details of the event below:

The November 2019 meeting of LRUG will be on Monday the 4th of November, from 6:00pm to 8:00pm (meeting starts at 6:30pm). The venue, FT near St Paul's, is provided by the FT. Full venue and registration details are given below.


Call the Cops: Bringing style to a lawless codebase

Scott Matthewman says:

Working with legacy codebases can be tricky at the best of times. What can make it worse if there’s no consistency in style. Linters (and Ruby’s RuboCop in particular) can help us write good code going forward – but what about the code that’s already there? There are good ways, and bad, to get RuboCop to help.

Disk is fast, memory is slow. Forget all you think you know

Daniel Magliola says:

Adding metrics to your code should effectively have no impact on performance. When we were recently tasked with doing that in multi-process Ruby servers, we ran into an interesting challenge: could we aggregate our numbers across processes without blowing our target of just one microsecond of overhead? In the process, we found some very counter-intuitive performance results that I'd like to share with you.


We're hoping to find a nearby pub for socialising after the talks (which should be wrapped up by 8pm) - suggestions welcome!

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.

Venue & Registration

Prior to attending you should familiarise yourself with our README paying close attention to the code of conduct which applies to all attendees at the talks and afterwards in the pub.
