    The dangers of free cloud-based storage

    A few days ago, Google Docs locked out many users from their documents, claiming they violated their Terms of Service, despite being innocuous. Here is why this will continue to happen what you can do to not run into this problem yourself.

  • Modern ejabberd configuration

    Modern ejabberd configuration

    ejabberd is one of the most widely used XMPP servers. It is easy to get it running for text-based messaging with a few configuration changes. However, to obtain a smoothly running modern feature set is harder. The configuration documentation is detailed, but even for a seasoned systems administrator or XMPP guru, a lot of questions […]

  • XMPP server hands-on comparison: ejabberd vs. Prosody

    XMPP server hands-on comparison: ejabberd vs. Prosody

    Having been involved in testing an open-source XMPP web client (JSXC) against ejabberd and Prosody, I have noticed the following differences that I would like to share, to make it easier for you to decide.

    XMPP: Chat with a Future

    XMPP is the Extensible Messaging and Presence Protocol standardized by the IETF. This standard provides the framework for doing anything you want to do with chat, and more.

Its well-known and frequently used interface beats the learning curve on the more scalable poll(), epoll(), or /dev/poll interfaces, especially if only a few file descriptors have to be monitored. select()’s younger sibling, pselect(), adds […]
