deltasql with new Freepascal/Lazarus client

I am quite proud of the new deltasql release 1.4.0, as it features a client completely written in Freepascal/Lazarus. It contains some of the libraries written for the GPU II platform, and some more stuff I will use to write an applaunch plugin for GPU II. I will test this plugin together with the anagramas plugin, developed as technical fallback from code written for hacker.org.

Echolink on Android

I tested the Echolink app on the Android phone of virus (HTC Legend). I connected to node HB3YGE-L two kilometers from my house. When I spoke the QSO handshake sequence,
it came out of the Yaesu FT60 with a delay of approximately two seconds. It worked also the other way round, speaking into the Yaesu FT60 echoed on the Android phone. I then connected to a node in New Zealand and heard ham radios talking, unfortunately I could not understand their English.

There is something which I miss on the Echolink app: I'd like to have the node number information along with the node name, so that I can connect to the nodes with the Yaesu FT60 by using the Echolink DTMF commands. I list them here as a reminder, the text is from the previous link.


Info Request: By pressing "*" will ask the Node to play an ID message.
Connect: Enter the Node ID number of the station you want to connect to.
Random Node: By pressing "00" the system will connect you to any available Node.
Random Link: By pressing "01" the system will connect you to any available Link or Repeater.
Disconnect: Press "#" to disconnect.


Virtual Academies

Life is definitely worth living :-), in the sense that the same named challenge on Hacker.org finally got solved, after destroying our best equipment. "Countdown Calc", "Patience" and "Blackbox" were interesting as they spaced on the decompiling domain. "Number Theory" and "Primal Pi" brushed up my aging C++ knowledge. "Filtration Residue", "Blood, Toil, Tear and Sweat" and "Dejà vu" taught us a lot. "Right Key Left", "My Chemical Romance", "Hereditary" and "Yoga Message" were pure fun. New tools discovered are Boomerang Decompiler, Hercules Emulator, Scilab and the NTL library. The challenge on which I hope to learn most is "Anybody Out There", although my mathematical skills are quite poor when it comes to signal analysis.

Problem is now that there are two castles, one protected by "Superbrainfuck", the other protected by "Spiral Bits". We have prototypes to solve the two challenges, but they still do not work :-(. And no way to execute "Execution Style", nor "One Function". Is this the end of our journey on hackerland?

For the record, our current ranking on Hacker.org is 239 with 157 challenges solved. Also Khan Academy published some more exercises (137/149)... Virtual Academies are the best escape path for Alice in Dilbertland!
