That will make a difference. If its Windows then the ctypes module will give you access to the Win32 API. You will need to refer to the Microsoft documentation to figure out which API calls you need and how to intercept them. Its all pretty easy capturing them for your own app, but when you try to track events outside your app it becomes pretty low level and depends a lot on the individual OS, so we can't really give general advice. > My idea is to do this with a thread. What can you suggest me? I'm not sure why a thread would help since its event driven. You should just be able to catch the events as they come in and update a data store of some kind.

For example...if I want to make an application for distribution to others, either for sale or as freeware, and I use the installers option as you mentioned, it is only proper to indicate this to the end user, such as, "In installing this application, the Python programming language and some other libraries will also be installed on your computer." But that might trigger a common psychological response from the user, "Oh, no, not a whole complex set of things installed on my computer that I don't understand, have never heard of, and will only need for this one application" But downloading a single .exe file and maybe a small folder of images or a few .dll files doesn't conjure that sense. If I understand it right, the .exe has Python bundled into it anyway, so such an end user's response isn't strictly rational, but you can see how people might feel this way in an age when there are so many ways one should mistrust software. Another reason is that, as I understand it, making it an .exe obscures the code (at least enough to make it take a bit more work to reveal the code). For some this might be a benefit?

I was under the impression that managers e-mailed their workteams if they needed to talk to groups of people. If the people are on an intranet, there shouldn't be any firewalls blocking their communication. The firewall would be between the computers and the internet, correct? The point of a firewall is to block all traffic which may be harmful to computers behind it. If your software listens on port 80, this is an abuse of the firewall spec, IMHO. The reason people are willing to open port 80 is because they know the only thing that will be listening on the other end is Microsoft IIS or Apache, both applications which have been under constant, stable development for years and have good security. Putting an application you just wrote from scratch with no regard to the security of it provides hackers an entrypoint into your network via your application. In addition, I doubt the managers would move to universally supporting your application - many of them would desire to continue to use e-mail for communication - and this would result in the workers having just another intrusive application they have to leave open all the time, as they're already required to leave an e-mail client active, I would guess. Anyway, I'm just a college kid with no experience in this kind of stuff, so if I'm completely wrong then correct me, but that's how I'd see it as working.

My approach is valuable because iit is so simple, and does not requirte the opeininig of new ports in the fireewwall of a site- it opperates through port 80, the http port.

Or games that require DirectX? People don't have problems with these. As far as I'm concerned, I'd rather have 45k of source plus the data files, than an extra 10mb for Python that I already have installed. Game downloads don't include DirectX for this reason - it's an extra 100 megs when most people will have it, or will have it after they play their first game. So they put DirectX on the CD, and in the game install, they ask you if you'd like to download and install DirectX if you don't have it already. That's how I think python installs should work. Just have a little check box that says "Download and install Python if you don't have x version or later installed." That's not any more intrusive than these other applications that force you to install stuff. In fact, it's less intrusive than .NET applications. It takes forever to install the .NET framework, and I have to navigate through web pages on microsoft.com just to find it! > But that might trigger a common psychological response from the user, "Oh, > no, not a whole complex set of things installed on my computer that I don't > understand, have never heard of, and will only need for this one > application" So add it to the 'custom' install path, and on the 'default' install path, just scan for Python and install it automatically for them if they don't already have it.

It makes an exe and a library.zip that contains all the python code. so one could simply extract the code from library.zip and use it that way. And you might say 'well, the code can be byte-compiled to make it more obscure.' Sure, you could do that. You could also do that without py2exe'ing it. I believe py2app or pyinstaller or something like that actually includes your code in the .exe, but py2exe doesn't. > I may be way off base here, just throwing it out as something I've wondered > about. > No, everyone thinks about this stuff whenever they consider if they should make .exe versions. Personally, I find in most cases it's just a waste of bandwidth and time to make .exe versions. But then, I haven't sold anything I've written yet, and my target audience is usually other programmers. Honestly, though, Python's easy and quick to install, especially compared to Java. I don't think it should be a big deal. This sort of thing has to be taken on a case by case basis - determining who's the user base, their level of technical knowledge, their aversion to installers including things they've never heard of, things like this.

That is the general idea. Some places have several submets and for security reasons channelize and limit communications between them. This is simple enoug to install that the group manager's workstation can mount a simple server for it to use, avoiding the need to breach the wall. banks come to mind as a place where there is considerable need for ligh level security within the firm, devloping something which is classified is another office environment where it would be needed. > > The point of a firewall is to block all traffic which may be harmful to > computers behind it.

I think you need to look at the basic X windows event model. In particular look at how Window Managers like twm/fvwm are written. Or the ubiquitous xeyes applet. It tracks the mouse all over the screen so must catch the mouse events before forwarding them to the applications. These are written in C but should give you a clue as to which events to catch and which windows/event queues to monitor or API calls to make.

You could but most Java applications don't warn you that they are installing the Sun Java JRE onto your system they just do it. And VB apps don't usually say they are installing VB DLLs on the system. Of course Python is more than a DLL and you might like to delete the documentation and sample programs to save the user space. But a more realistic example is programs which turn on Active Scripting on a Windows PC. This enables people to write and run VBScript of JScript programs.

This is valid but its arguable by how much and whether it would deter a dishonest pirate much more than a compiled python module. Or you might prefer to do a Jython version of your code and distribute as a Java program instead. > I may be way off base here, just throwing it out as something > I've wondered about. These are valid points but I think they are often grossly over played and the reality is most folks just think exe because its what they are used to. IMO Its very much a Windows thing, its very rarely done in Unix land because there people are accustom,ed to interpreted applications (in sh, awk, perl, tcl, m4 etc) and their need of an interpreter. If Unix users can live without it why not Windows users. Its a matter of changing culture rather than any real technical advantage.
