I’m not a fan of Maven. I don’t make any secret of it. But one thing they’ve got right is the “provided” scope – that is, a scope whose dependencies are used at compile time, but not required at runtime because they’re expected to already be present. The canonical example of the use of this [...]
Actually, I’m pretty sure it isn’t, but still… From spinning up a new EC2 instance today to getting the first e-mail from fail2ban took a little under 6 hours. I don’t know if this makes me happy or sad. Happy because I have a Puppet-based bootstrap system which can bring a freshly minted box up [...]
A quick note to try and save somebody else the hours of pain I just experienced… Here’s the scenario: you’re being dead clever and ditching Apache in favour of Nginx to run your WordPress blog/site and pretty much have everything right. You’re NOT using a plugin to generate robots.txt for you – after all, WordPress [...]
A little under a year ago, I decided two things: first, that it was about time my ageing home network got GigE and 5GHz wireless-N (dual band, of course, to support devices that would only do 2.4GHz); and second, that I would separate the jobs of BEING my network from CONNECTING my network to the [...]
iOS 5 is upon us, so I thought I would snag a copy and see what’s what. But, first thing’s first… I apparently needed to upgrade iTunes to 10.5. (Why? Why do I need a particular version of a media player to install a particular version of a mobile phone OS?) I’m running Windows Vista [...]
It’s interesting to see people getting interested in porting the Disruptor to .NET (although what’s wrong with The One True Language, I don’t know!). Tim Gebhardt has a port on Github Matt Davey (Technical Director at Lab49) also has a couple of posts about porting the Disruptor and comparing the performance of his port to [...]
In case you’ve been living on another planet, we recently our high performance message passing framework. I’m going to give a quick run-down on how we put messages into the ring buffer (the core data structure within the Disruptor) without using any locks.
LMAX recently open-sourced The Disruptor – one of the core frameworks upon which we build our ultra-high performance financial exchange. Today, we published a white paper detailing how The Disruptor works, and highlighting the sorts of performance benefits that can be achieved by using it. The Disruptor is essentially a library which we (and now you!) [...]
Following on from , my colleague, Adrian, has given the issue some thought and written an excellent post explaining his position. His conclusion is that we should simply not be marking classes as final because it really doesn’t bring any benefits. Even if you’re trying to follow Design by Extension, the next guy is just [...]
After almost a year with no work, Parallel Ant 0.9 beta is finally released. More info on the page.
