It's always good to get some feedback on a blog post. I was pleased when several members of makandra GmbH took the time to watch, analyse and discuss my recent screencast about Presenters in Rails.

makandra published a blog post with their thoughts. I responded to several of their comments and decided to also post them here.

(Henning) Bad: The presenter accessors don't do any typecasting, so everything is a string all the time. This could have been done more elegantly.

(Arne) Bad: No automagic type casting on attributes – this can't be fun and there surely is a way to get it.

Congratulations! You are now the Product Owner on an Agile project. Maybe your boss gave you the role, or perhaps you’re working with an agile agency and you volunteered after learning a little about it. Either way, now you have a problem: people are already asking you "When will the product be ready?"

It doesn't matter if it's your boss wanting to know when you will deliver the product, or if it's your customers wanting to know when they can use shiny new features, or even if it's the voice in the back of your mind wondering when you can ship the Next Big Thing. Someone wants to know.

Our 4th meetup was held at the Skimlinks office.

We had about 70 people in the meetup twice as big as the last meetup.
Special thanks to @CiaranR, and @skimlinks people for providing the venue, pizzas and beers again (it's the first time we ran out of Peroni).

We had 2 speakers, Tim Ruffles(@timruffles) and Alastair Maw(@herebebeasties) and here are the links to each talk.

(NOTE: We took videos, and will update them once edited)

In my last blog post we took an overview of using code reviews to increase communication and knowledge sharing between remote teams in Agile projects.

Since we use GitHub it was natural to turn to them for code reviews. Happily GitHub's code review tools are very nice.

Much of this will be familiar to you if you already use GitHub, but for clarity here is the step-by-step process:

1. Work on a new feature branch
2. Merge feature branch to the staging server so that it is visible for QA (Quality Assurance)
3. Push feature branch and create a Pull Request
4. Wait for QA and Code Review
5. Merge the Pull Request

There is nothing like face-to-face contact to get an important point across or to fully benefit from planned (and unplanned) team interactions. Still, there are times where it's just not possible.

I've been working with a client in Kent over the past few months. Clearly, it's not practical to move the entire New Bamboo team down from London for the day. To complicate things further, the client has development teams in multiple places around the UK.

I've recorded a short, 10 minute screencast about presenters to give you a good view of what they are, where they came from and what they're good (and bad) at. It's illustrated with an example from our recent work on a loans processing application for the UK government.

Presenters allow you to create simple, understandable, self-contained objects. The screencast goes a little further than Jamis Buck's ‘skinny controller, fat model’ dictum to arrive at ‘skinny everything’.

Search is an important part of any application: users instinctively know where to look when they want to search within your site. For many users search is often the preferred way of getting to the functionality they want in your app.

Implementing search usually involves some external process which manages indexing and handling queries against your data, such as Solr or Elastic Search. This is often a secondary piece of your application's architecture, and is yet another service to host and maintain. For some sites or applications this extra overhead can be an additional layer of complexity too far.

As programmers, we might sometimes fall into the trap of thinking our ideas - and the user experience they provide - are fine, because they work for us and we can adapt to poor interfaces without much problem. Put the same idea in front of an audience, however, and you're in for one hell of a refactor if you wrote the code beforehand.

This is a story about the two days I spent prototyping a new feature with the BBC; how figuring out the UX was far more challenging than writing the code could ever be; and why nothing could possibly be more entertaining than X-Factor.
