• DNS protocol message example

  - by virtual-lab

  hello there, I am trying to figure out how to send out DNS messages from an application socket adapter to a DNSBL. I spent the last two days understanding the basics, including experimenting with WireShark to catch an example of message exchanged. Now I would like to query the DNS without using dig or host command (I'm using Ubuntu); how can I perform this action at low level, without the help of these tools in wrapping the request in a proper DNS message format? How the message should be post it? Hex or String? Thanks in advance for any help. Regards Alessandro Ilardo

• Mobile Application development - get hands on at UKOUG

  - by Grant Ronald

  Development of mobile solutions is one of the hottest topics in the IT market at the moment.  Forbes predicts that mobile application development with outstrip native PC development by 4-1 by 2015.  I'm therefor delighted to announce that the UKOUG and Oracle have synch'd up to provide a rolling 3 day hands-on Mobile development lab at the UKOUG conference this year. We're setting up a lab of 10 Mac machines in which you will be able to develop iOS on-device applications.  And the great thing is, if you want to develop for Android, its the same lab as well!  Just think, write once and deploy to iOS or Android.  We know places will be limited so we are going to be putting in place a first-come-first-served booking system.  Walk-ups will be allowed only if places are free. This is your chance to start skilling up on the hottest development initiative in years.

• What's the right way to communicate between 2 or more .Net applications running on a same computer w

  - by Ivan

  If my applications run on a same computer or even on different computers in a same LAN and need intense and quick communication, it seems illogical for me to use text-encoded web services and HTTP. I could possibly use IP/TCP/UDP sockets and invent my own protocols, but believe there is a standard way for .Net applications to send/receive object instances (and, maybe, even sharing an object by reference?). Can you tell me what's that standard way? I am only interested in .Net Framework 4 applications and don't need to support legacy frameworks.
