Hi all<div><br></div><div>Just following on from my request at the meeting yesterday; I've built <a href="http://rocketsports.co.uk">rocketsports.co.uk</a> on ruby (or rather my developer has!; and a great job he's done I have to say) however he's unfortunately not able to commit much time moving forward due his wife having just had a baby (great news!); however I have a white label solution to build and launch, ideally before October as I'm working with HSBC on a large event, that they're sponsoring - that the white label solution will need to be ready for to organise!</div>
<div><br></div><div>So if there's anyone around for aprox 5/6 weeks solid (or if you have other projects on perhaps 3-4 days per week - I'm quite flexible) to build the white label solution on a fixed amount of cash and get this out to market; and then if possible potentially ongoing on an hourly rate to help with adding features and tweaking things, let me know. </div>
<div><br></div><div>I'm speaking with some good folks overseas but it would be great to have someone more locally.</div><div><br></div><div>Let me know if you or if you know of anyone else who maybe interested.</div>

Thanks for a great presentation Tim, very useful!<br>
Question I forgot to ask was, after the refactoring, how fast was that 1min<br>
page load?<br>
<br>
Cheers!<br>

<br>
<br>
Heh, I can't actually answer that right now, as the 1min page load was on a specific set of data in our production database that's long since gone (I think someone had set up their entire company's work as a single project, which meant it was doing rather a lot of work when something was rescheduled). I will dig it out of backups and try it again at some point though, as it'd be a really useful metric to judge how much we've improved.<br>
<br>
To give a (slightly) more concrete answer, my back-of-an envelope calculations suggest that our old model scheduled new tasks in time of order O(n^2) where n is the number of tasks in a project, and the new model is O(nlogn), (as it's just Enumerable#sort), where n is the (smaller) number of tasks assigned to a specific user. Put even more concretely - while there's a cost associated with working out the priority of a task, we no longer need to recalculate this for *all* the tasks in that project, leading to a susbtantial saving.<br>
<br>
The other advantage we have is that (while we haven't done this yet, as that *would* be a premature optimisation IMO) decoupling the scheduling code from the rest of the system as far as possible will make it far easier to use a work queue like structure to process these potentially-expensive operations outside of the request/response cycle if we need to - this would have been totally impossible under the old system.<br>
<br>
So, the short answer is "no idea, but i'll find out!" We've been able to measure performance benefits to a reasonable degree in other ways though.<br>
<br>
Cheers,<br>
<br>

Hello LRUG<br>
<br>
Just a quick email to say that Headshift is looking for Rails developers.<br>
<br>
Details of the positions are on the Headshift site [1] but broadly we're looking for a few able middleweight / senior / lead developers to complement our existing growing team on primarily permanent but also contract roles.<br>
<br>
The projects are suitably challenging and rewarding, and we'd be looking to kick off another workstream around beginning of September.<br>
<br>
We're located [2] just off Shad Thames, next to the Design Museum so you'll get plenty of exposure to the area around Tower Bridge.<br>
<br>
We also attented LRUG last night, but if you didn't spot us there, and if you are interested, please email your CV or get in touch at iwanttowork(at)headshift(dot)com. And as always, Headshift does not work with recruiters.<br>
<br>
Thanks for your attention folks!<br>
<br>
Alex<br>

OK, I'm sure this is one of those things that everyone else knows about<br>
except me[*], but Googling is getting me nowhere.<br>
<br>
Is there a gem or a standard idiom for creating Struct-like classes<br>
whose #new method accepts named parameters (corresponding to the<br>
accessor names) instead of arguments by order? I would like to write,<br>
for example<br>
<br>
class Book < NamedStruct.new(:isbn,:author,:title,:review_rating)<br>
b=Book.new(:author=>'Ian McDonald',:title=>'Brasyl')<br>
<br>
# and in approximately rspec syntax<br>
b.title.should == Brasyl'<br>
b.review_rating.should be_nil<br>
<br>
If there isn't then I could probably stand to improve my understanding<br>
of Ruby metaprogramming significantly by writing my own, but it seems<br>
like the kind of wheel that must have been reinvented many times<br>
already, and surely by now someone has made a nice smooth round one<br>
