In this short video, Simon Maple and Andy Stanford-Clark show the new WebSphere Liberty Profile interfacing with Really Small Message Broker (RSMB) via an MQTT client (eclipse Paho). This results in MQ messages being sent to control devices 50 miles away on the Isle of Wight!
Learn how to build simple yet powerful RPC code with ZeroMQ, with very few (if any!) modification to existing code. You'll see how to build fan-in and fan-out topologies with ZeroMQ special socket types to implement PUB/SUB patterns
There are some weird APIs out there. That's what Craig Neslage found out when he looked through APIhub - a giant hub for APIs similar to ProgrammableWeb. Let me give you an idea of the weird level we're talking about here...
A puzzler was given before, and all submitted solutions were based on the iteration: x_n+1 = (x_n + x/x_n) / 2. That formula is great for finding good rational approximations of the square root of a number, but it's trivial once you know the formula.
I recently talked with Dr. Jim Webber, the chief scientist at Neo Technology, to get some insights into the current events around graph databases and some background on the the widespread growing interest in graph dbs.
I’ve been trying over the last couple days to list all the different memory patterns I can see myself using. I’ve also tried to pull out systems I know of that do the same for comparison, although I can’t find direct equivalents in all cases.
With the release of a new version of the open source graph database, Neo4j, and the fast-approaching Graph Connect conference (the first EVER graph database-focused conference, btw), we thought it'd be a good idea to talk to a couple of leaders in the graph database space.
A new version of Go, the Continuous Delivery managment tool by ThoughtWorks Studios, is up for grabs today with a feature that is going to help package the right versions of your components and eliminate spurious builds.
So how many in the developer ranks have already taken the initiative (or been forced) to learn multiple programming languages and use them to create non-trivial applications? That's what you're about to find out when you finish this poll.
