UML…

using UML is the best way to keep everyone talking the same language and agreeing upon how to approach problems with an eye for consistency and easy-understanding for future developers.

Securing Web services: Using XML signatures

An important consideration in the creation, deployment, and use of Web services is the message itself. Since Web services rely on the transmission and receipt of SOAP messages, the ability to verify the integrity and authenticity of these messages should have a rather high priority associated with it. Further, since Web services are often used to present commercial transaction interfaces to potential customers, message non-repudiation plays a key role in these scenarios. The XML Signature specification, a W3C/IETF effort, addresses these problems by providing a digital signature framework for XML documents based on standard public key cryptography notions, as discussed in an earlier article. more HERE

Linux Incompatibility List

The #Linux Incompatibility List is an attempt to catalog and document hardware/peripherals of all kinds that do not work with the #Linux operating system. Fortunately, at this point in time, there is far, far more hardware that works without any problems with #Linux, so this site aims to make #Linux users aware of hardware to avoid

Caliber 1

If you have a problem with this helicopter or with another heli brand, I recommend you to visit the http://www.raptortechnique.com site. Most of the problem has been already solve for the raptor 30. Since all heli share the same design (and problems more or less), you can find many tips and idea for your heli.

Danger part ca3035 main mast stopper caliber 30

	Kyosho part CA3035 Some parts right out the bag are prone to break. Verify yours and replace them wth a raptor 30 if needed! “Almost directly accross from where the set screw is installed was an imperfection in the aluminum. I pulled on the part with my hands and could spread the piece and it proceeded to break in two. I also tried the same thing on the part with no visible problems and it would not budge.” by choppengruven Discover by in France by Claude and Laurent Lombard

Dual Battery system

 Overall view of my 1st caliber

24.08.2002 Add a dual battery system for more safety. I have no heli with only one battery. Here is why:

Problems	1 battery pack	2 packs + mechanic Switches	2 packs + Electronic switch
Additional cost of system	reference	+ 55€	+ 180€
Open circuit between battery and switch’s pack	Failure	Redundant	Redundant
Open circuit in one of the pack	Failure	Redundant	Redundant
Battery short circuit in one pack	Failure	Failure	Redundant
One pack not fully charged	Failure	Redundant	Redundant
Switch failure (assumes between RX and backup sys)	Failure	Redundant	Failure
Battery connector from backup system to the receiver	Failure	Redundant	Failure

Build yourself a dual switch
