I have been looking at the ZeroMQ zero copy pages for a project. I’ve dipped in and out of ZeroMQ over the last few months but am looking at it in a different light. I’ve been building some toy applications with it to greater or lesser success, such as File transfer system, and so on. […]
This talk was originally given at the lightning talks session of the Oxford Accu group. The updated slides are on my account on Slideshare. These are the fleshed out notes of a talk that I gave that evening based on experiences and experiments. It does contain some responses to questions and points raised. It is […]
Recently I scratched an itch and posted a module onto Drupal.org as a sandbox. It is perhaps slightly misnomered in “Bean Stomp” which is its development name. It is an integration of Jeff Mesnil’s Stomp over WebSockets JavaScript library which allows real time updating of a page without polling or similar overhead. I had been […]
In my last post about monitoring ActiveMQ, I looked at various advisory queues. I also mused on the possibility of reading the stats from the queues and topics and parsing them so that if issues occur, they can be dealt with quickly rather than waiting for an issue to be reported. Although this information is […]
In my last post on ActiveMQ, I mused on using mirrored queues to keep a message store for varying reasons. It is a naive way of doing this but it showed how such a thing can be done quickly. As part of some ongoing explorations into operations and governance of MQ systems, I have also […]
I have been doing some digging into monitoring queues on ActiveMQ and pushing the messages into a message store for what ever reason. The main reason for doing this would be monitoring error messages and giving developers and operations a way of exploring what is happening in a queue if data at a recipient system […]
I went down to the London Realtime event event today. In part, it was to learn more about realtime programming and partially because RabbitMQ were going to be there and it would be a good chance to talk to somebody about the message queueing (MQ). I did manage to bend somebody’s ear (sorry if I […]
A recent work project has been working with messaging queues and exploring how they work. One of the issues has been how to get systems running different systems to talk to each other. One system uses ActiveMQ and another runs RabbitMQ which has led to some interest in how to effectively bridge the systems into […]
As part of the synchronisation part of a project, I’ve been trying to integrate systems together with a messaging system. This is not a trendy decision but one based on scalability and flexibility at the core. I wrote a micro-messaging server for my previous job which was dealing with a few hundred messages per day […]
It has been a while since the last weeknotes. I’ve finally made the move to Linux, or at least dual booting, by installing Ubuntu so I’m currently learning a little the OS and getting a development environment set up for it. I’ve nearly finsihed the ongoing accounts project at work. The framework is up and […]
