  • Three method calls that make all the difference

    I’ve been coding like crazy the last few days 🙂 on an astronomy-related application. I had to remember lots of trigonometry from 15 years ago 🙁 The application is supposed to be a tool for discovering white dwarfs in our galaxy utilising information from astronomical archives (e.g. SDSS, SuperCOSMOS) through the use of Web Services.…

  • W3C WS-Addressing WG

    It was about time! The W3CWS-Addressing WG has been formed. Good luck to Mark who’s chairing it! This spec and SOAP are, to my mind, the most important in the WS world. Remember… It’s all about the message.

  • Are resources the new objects? Proposal to rename “Web Services” to “Distributed Objects Revisited”

    Yup, yet another spec; this time for managing resources. It’s called WS-Management and I guess it’s in direct competition with the WS-RF-based WS-Distributed Management (WS-DM). Oh well 🙁 It seems that this specification follows the recent trend to reason in terms of resources instead of services. I really enjoyed the following while reading the WS-Management:…

  • WS-Transfer and COM IUknown?

    I don’t know the details of COM so I wouldn’t recognise the GUID for IUknown. I was suprised to see COM’s IUknown interface makes an appearance in the WS-Transfer specification. If you look at the second example the WS-Addressing MessageID is 00000000-0000-0000-C000-000000000046 the GUID for IUknown. This was from Benjamin Mitchell‘s blog. There is no…

  • Utility computing centre closes

    TheRegister reports that HP has killed its “utility computing experiment”. Was this doomed to fail or was it ahead of its time? I always believed that “Grid computing” was more about hype, politics, and marketing rather than technology. Here at Newcastle we’d like to think “Grid computing” as an application of the distributed computing ideas…

  • Tim Ewald on WS operations

    Tim Ewald suggests that Web Services only have 4 simple operations (input, output, input/output, output/input). I think that Tim really gets it but I would have to disagree with this particular comment since I don’t see these as operations; I see them as message exchange patterns. There is only one logical operation supported by every…
