DXHC-Reward certificate ideas

The normal DXCC award is 100 countries, right…
So I was thinking doing the following.

DXHC, DX Hundred Club or DX HamSphere Club

25 verified countries = Bronze Award including a 1 month subscription
50 verified countries = Silver Award including a 3 months subscription
75 verified countries = Gold Award including a 6 months subscription
100 verified countries = Platinum Award (The real DXHC Award) including a 1 year subscription
150 verified countries = Diamond Award including a 2 years subscription

A verified QSO is when QSL cards has been fully exchanged.

Open for comments.

DXHC-Reward certificate

Greetings blog readers!

It has been some time since I updated the blog. Since my last update we have released the April 2012 newsletter and started testing multi-path propagation on HamSphere. You can try this mode on the SE server using the 40 meter band.

Other things in the works: Completion and securing the server platform including database replication. Also we are still working to get the new master server fully operational.

Interesting upcoming projects: Currently I am also working on on a DXHC-Reward certificate (DX HamSphere Club). Operators will be automatically issued Bronze, Silver, Gold and Platina awards depending on the number of worked countries (Fully Verified via QSL cards) when they have reached the targets. There might also be other benefits like extended subscriptions etc for DX achievements.

Logbook and QSL statistics

Finally I am finished with the Log book and QSL statistics page.
I hope you will like it http://www.hamsphere.com/logstats.php

New Main Server

The new main server has been installed and it is now up at server6.hamsphere.com
Perhaps you can give me some ping feedback. It seems a lot faster and I am currently transferring data from the old server. We will run both main servers in parallell until July 2012.

All servers up

After 10 hours work I found the reason for the replication problems and managed to fix it. Database replication is clearly not a walk in the park. Since we have many servers, we always need to let it run for some hours before you can connect the Database “daisy chain” together for full replication. If you connect the chain before it is properly synchronized, the whole system gets instable and starts oscillating with corrupt data as a result.

All servers are go.

Replication problems

The HamSphere network is using database replication between the servers.
Today I have changed the replication order to optimize the data flow.
Server US, IS,GB and AU will be down during this maintenance.

Update

Android / iPhone apps are delayed due to server work. I am still working on transferring data from the old master server to the new. Also I am currently working on the log statistics and report system which is nearly completed.

Code writing

Been writing code all week. Working on the extended server platform.
There will also be a newsletter released in a few days.

REPNE SCASB

When I started writing code back in the 70′s it was all assembly language mnemonic instructions. My first CPU was the Motorola 6502. But soon I would turn into on the Intel track opening up a whole new world of instructions in the 8086 CPU. One of them, “REPNE SCASB”, popped up in my head today. That was an assembler instruction I used quite a lot. (Scanning strings)

And I couldn’t resist thinking of how many REPNE SCASB instructions that are executed even today on every single Intel based server in the world every microsecond. It must be trillions!!!!! Amazing!

Iceland Cloud server

Between 2001 and 2005 I worked at lot with a company on Iceland called Idega HF. I was hired by a Swedish company called CubeCon who used the Icelandic company to develop a rather big platform for the Swedish school system using the idegaweb Java beans J2EE framework. We worked together for some years.

Two of the minds of Idega HF started up a new company called GreenQloud which is a Cloud Server computing company using “green” energy. As you probably know, Iceland has a never ending, abundant stream of and ample energy resource called Thermal Heating which can be converted to electricity. This is what powers the GreenQloud servers.

It felt natural for me to try their platform out for HamSphere and the result you can see now when you start the HamSphere transceiver. Connect to Reykjavik, IS server and you will find it very fast an reliable.

Have in mind that the Icelandic server has a slightly different propagation model based on its location in the North Atlantic. The Icelandic Radio and TV broadcast company have some podcasts relayed on the BC band.
