• Expected output from an RM-1501 RS232 interface?

  - by Jon Cage

  I have an old RM-1501 digital tachometer which I'm using to try to identify the speed of an object. According to the manual I should be able to read the data over a serial link. Unfortunately, I don't appear to be able to get any sensible output from the device (never gives a valid speed). I think it might be a signalling problem because disconnecting the CTS line starts to get some data through.. Has anyone ever developed anything for one of these / had any success?

• Generate an LTPA token?

  - by Shadowman

  We have a need to integrate a server with our WebSphere environment that does not support LTPA. I found the blog post here and corresponding code to decode the information in an LTPA token.

• What is the security advantage of STS in web services?

  - by Neil McF

  Hello, I've started reading up on security (particularly authentication) with web services and I see a lot of references to security token services. From what I see, they take a username-password (or something) and, on validation, return a digital token. How is using this token any more secure then just relying on the username-password in the first place?

• Are there existing web sites that use a photo as a electronic signature?

  - by Alessandro Vernet

  The use case: to sign a electronic document, users view the document, and if they agree take a picture of themselves with their webcam (done through Flash from the browser). Then a PDF is generated containing the document and the picture in place of signature. This is a biometric signature, which is not as strong as a digital (cryptographic) signature, but stronger than having users draw their signature, as a photo is harder to forge than a drawn signature. Has anyone seen this technique being used on an existing web site?

• What is the correct terminology to describe a visual display that is about the size of a living room

  - by JW

  I'm thinking that, as flat screens get bigger and cheaper it won't be too long before 'digital wallpaper'-like screens become popular in people's living rooms with a host of applications that could take advantage of this particular screen size/resolution. Is there a proper name for this size of screen? 'Wall Screen' - is too ambiguous 'Massive Screen' - is probably best reserved for something you'd put on the side of a sky scraper 'Small Screen' - nabbed by the mobiles 'Large Screen' - kind of means desktop I'm thinking of the kind of screen used in 'Minority Report'.

• Are there any lightweight analogues to CORBA/RPC for embedded programs?

  - by Mtr

  I am writing embedded applications for different hardware (avr, arm7, tms55xx…) and different rtoses (freeRTOS, rtx, dsp/bios). And every second of them needs to communicate with PC or another digital device. Sometimes interactions logic is very advanced. So I'm interesting in common methodology (like state-machine programming style), protocol specification or library, that could simplify developing such things.
