Dear Paul,

We are sending you this email because you purchased our 330X Aero Spy Conversion Kit in your order #xxxxx. We just realized GAUI have revised their 330X kit a bit in the gear mount after our Aero Spy Conversion Kits were made. This will cause the problem that the mounting holes of CF Landing Gear legs in the conversion kit are not able to fit the revised 330X kit. We are asking the factory to revise the landing gear legs accordingly and urgently, and will send you the update pack with the revised legs in a couple days probably within next week.

By the way, we also noticed the originally packing list of the Spy Conversion Kit does not include the mounting bolt for camera. As people may have difficulty in find the suitable screw locally by their own, we will include the screw in the kit. This screw will also be included in the update pack.

Feel free to let us know if you have further questions anytime. We will appreciate any comments or advice you’d care to give. Sorry for any inconvenience caused.

Have a great weekend!

Regards,

Infinity Hobby

I hereby put this code into the public domain.

Presentation I held last year for my colleagues at Adresseavisen.

Eventually Consistent: “This is a specific form of weak consistency; the storage system guarantees that if no new updates are made to the object, eventually all accesses will return the last updated value. If no failures occur, the maximum size of the inconsistency window can be determined based on factors such as communication delays, the load on the system, and the number of replicas involved in the replication scheme. The most popular system that implements eventual consistency is DNS (Domain Name System). Updates to a name are distributed according to a configured pattern and in combination with time-controlled caches; eventually, all clients will see the update.”

In the same reading frenzy I also read these related pages:

I just watched this presentation and thought that I should share it with you. As a software engineer this is intrieging.

Anyway, after upgrading I wrote some test code to display the NMEA data from the GPS and guess what.. It worked!

        EDemoBoard edb = EDemoBoard.getInstance();
        edb.initUART(edb.SERIAL_SPEED_4800, edb.SERIAL_DATABITS_8, edb.SERIAL_PARITY_NONE, edb.SERIAL_STOPBITS_1);
        while(true) {
            try {
                System.out.print((char) edb.readUART(1000));
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

And the output (No fix. I was in my livingroom)..
