Hi everyone,

Well guys, we did it… 4000 members! What an achievement for our community. Massive thanks to all our members, sponsors, speakers, organisers and everyone that has been involved over the last 7 years. We are growing constantly, receiving an average of almost 800 RSVPs a month now which is fab. In celebration of this, I’d like to share with you the best comment we’ve ever received on our official Meetup feedback page:

“ The LJC is what would happen if the Avengers made babies with the staff of the Manhattan Project. And then brought them up in London. As programmers. ”

Thanks to Tom Anderson for that gem, I don’t think I could say it better myself! Please keep the answers coming. Things are not lightning up as we bring you this fortnights events from across the capital from LJC and our partners.

Lock Free Queue Evolution Continued!
Two months ago Nitsan Wakart gave the Lock Free Queue Evolution talk to 120 LJC members at SkillMatters. While the talk got great feedback Nitsan was unable to fit the content to the time slot. This is the second part of that talk, though background will be covered and no prior knowledge is required.

The London Developer Sessions
You absolutely have to get to this event – it’s the best place to come, drink beer and just socialise with other developers. Talk about projects you’re working on, problems your facing, advise a grad or two or just come to discuss anything you like. It’s a great chance to meet first time LJC members as well as seasoned professionals. The RecWorks crew will be there to give any career advice or new job opportunities. Really what reason do you have not to come along?

Testing and Refactoring Legacy Code
Working with legacy code is tough: no tests, no documentation, and the constant fear of breaking other parts of the code. The only way to deal with that is to test and refactor merciless.
For the majority of us, legacy code is part of our life and learning how to embrace it can make things far more enjoyable. In this full live coding session, Sandro Mancuso will be demonstrating how to overcome the most common problems found when testing legacy code. He will be taking a piece of messy Java code, test it until is 100% covered and then show how to refactor it in order to bring the business language and requirements to life.
This session is full of tips and tricks you can start applying immediately, and a good opportunity to see a craftsman at work. Although the code is in Java, the same principles can be applied in any Object-Oriented language.

Every fortnight, we meet for coffee, code, craft beer, and some great food.
This is a great opportunity to:

• pair with someone else on whatever you like (katas, koans, etc)
• ask someone to join or help you with your own project
• have a face-to-face meeting with your mentor or mentee
• have a nice chat over coffee and beer
We’ll be meeting in “Look mum no hands!”, a laptop friendly cafe/bar that’s open until 10pm, and sells great coffee, excellent beers, and some tasty food. They also repair bikes and hang them from the ceiling like chandeliers, because why not? http://www.lookmumnohands.com/
