Hello, How can I quickly generate an unique computer id for a delphi app? I used to do it easly with c#, but this failed sometimes. I do want the ID to be "static" but I don't care if the id changes because of a hardware change or OS reinstallation, I was planning to store it in the registry and check it when the app starts, and if it ch...
Ok this is a tricky one to explain. I am creating an app that will have PAGES, currently I'm using PageID as the key to SEL the record. The issue I'm having now is that I want users to be able to EDIT pages, but not lose the previous page (for history, recording keeping reasons, like a changelog or wiki page history). This is making m...

I know this is a big one. In fact, it may be used for some SO community wiki. Anyways, I am running a website that DOES NOT use explicit authentication of users. It's public as in open to everybody. However, due to the nature of the service, some users need to be locked out due to misbehavior. I am currently blocking IP addresses, but ...
This is a followup for this question. When I used the proxy flag with mod_rewrite, I did not know all of its effects. Now I have two more problems, which need to be fixed! The main problem is with user IP addresses, everyone appears to use the server IP. I can't trust http-x-forwarded-for because it is easy to forge headers, and the RE...
Hi, I'm programming for Windows CE and I need to connect to a scanner. There is no problem - I know that it is on port COM0, but if I plug in another device earlier it gets another COM port... to get all com ports the easy way is: SerialPort.GetPortNames() But I don't know how to identify a device? Is there any standard way? I can't ...
What are some fast and somewhat reliable ways to extract information about images? I've been tinkering with openCV and this seems so far to be the best route plus it has Python bindings. So to be more specific I'd like to determine what I can about what's in an image. So for example the haar face detection and full body detection clas...
We have a service where we literally give away free money. Naturally said service is ripe for abuse. To defend against this we do the following: log ip address use unique email addresses (only 1 acct/email addy) collect more info like st. address, phone number, etc. use signup captcha BHOs (I've seen poker rooms use these) Now, let'...

I use Maven to build my web app projects, when I add some dependent library to the pom file, it again adds some more dependent jars to the project recursively. Is there a way to find out or restrict that only jars having a certain type of license - say Apache License, BSD etc should be included. Or is there a way to find out that a jar f...

Hi Folks Planning to create a widget for client sites that uses jsonp to interact with my server. jsonp because i'll need to skirt the same-origin-policy (don't want to trouble clients with using server redirects), but i realize this limits me to http GET. I'll need users to login/identify themselves before they can interact more with th...
I developing a system that consist of 2 units; 1 Android tablet and 1 iPhone. My users will have to identify themselfs to the Android tablet (this should be done as user-friendly as possible with as few steps as possible and in a secure manner, meaning it should not rely on gps that is not exact). I have looked at various techniques, but...
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 ...
Is there any way or best practice around device fingerprinting for a rails app? In other words. Given that all cookies are blocked, is there any way, with a relatively good degree of certainty, who the person is before they log in? My assumption: IPs are unreliable for obvious reasons. ...
