sources of "uniqueness"/entropy on embedded systems
I have an embedded system. What I would like for it to do when it powers up or otherwise resets, is to generate a unique ID, so that on different restarts a different unique ID is generated with high probability. It does not have access to a real-time clock, but it does have access to an ADC and a UART. I am wondering if there is a dece...

Sorting jQuery Interactions of Multiple Instances, Each With Unique IDs
Hello. I'm expanding on what used to be a pretty simple jQuery accordion script, and I've made it so that multiple accordions can be placed on the page, each with its own unique ID.

Make unique id of just numbers?
In a program, I am trying to make unique id numbers. I used this way: AtomicInteger count = new AtomicInteger(0); count.incrementAndGet(); int pid = count.get(); System.out.println("pid: " + pid); But my professor said this: Another problem is the pid generation. All you are doing is getting the next integer starting from 0. What ...
Ideas on how to uniquely identify a computer?
I have been thinking of ways I could uniquely identify a computer in python. First, I thought about checking the user's mac address and hard disk space, then I tried to compute some sort of rating from many of these variables. However, this solution doesn't feel right.

Is it possible to get NHibernate to auto-generate an ID if the entity does not have one, or use the ID of the entity if it already has one?

I wanted to provide unique ID for different categories of models in my db. So I've introduced a dummy model : class GUUID(models.Model): guuid = models.PositiveSmallIntegerField(_(u"Dummy GUUID"), default=1) and in model that I want to have unique ID: class Event(models.Model): unique = models.IntegerField(blank=False, edita...

What would be a good order id scheme for a e-commerce solution or paid web service?
Considering the following: a) you want some confidentiality (as in not telling everybody how many orders you've received). b) you want a check digit (e.g., using the Verhoeff algorithm) at the end so you can easily tell misspells and help dealing with errors when scanning barcodes, if this is the case. c) you've to consider time so co...
