How can I package my Perl script to run on a machine without Perl?
People also often ask "How can I compile Perl?" while what they really want is to create an executable that can run on machines even if they don't have Perl installed. There are several solutions, I know of: perl2exe of IndigoStar It is commercial. I never tried. Its web site says it can cross compile Win32, Linux, and Solaris. Perl D...
Can you Distribute a Ruby on Rails Application without Source?
I'm wondering if it's possible to distribute a RoR app for production use without source code? I've seen this post on SO, but my situation is a little different. This would be an app administered by people with some clue, so I'm cool with still requiring an Apache/Mongrel/MySQL setup on the customer end. All I really want is for the s...
Python GUI Application redistribution
I need to develop a small-medium sized desktop GUI application, preferably with Python as a language of choice because of time constraints. What GUI library choices do I have which allow me to redistribute my application standalone, assuming that the users don't have a working Python installation and obviously don't have the GUI librari...
How would I package and sell a Django app?
Currently I am hosted a Django app I developed myself for my clients, but i am now starting to look at selling it to people for them to host themselves. My question is this: How can i package up and sell a Django app, but also protect my code from pirating or theft. Distributing a bunch of .py files doesn't sound like a good idea as the...
Scaling an application
I have an application (an IP conferencing service) that I need to scale. It has quite a few independent components/applications, written in different languages (mainly C++ and PHP, some Perl). Currently a single installation runs on 5 machines, with 1-2 components sharing a single box. The configuration of each box therefore is different...
Random distribution of data
How do I distribute a small amount of data in a random order in a much larger volume of data? For example, I have several thousand lines of 'real' data, and I want to insert a dozen or two lines of control data in a random order throughout the 'real' data. Now I am not trying to ask how to use random number generators, I am asking a st...

What are the iPhone app-name restrictions? (And [where] are they documented?!)
It took me 2 days (and a lot of head/wall pounding) to finally discover that the reason ad-hoc distribution wasn't working for me was because my app-name had UTF-8 characters. I'm still boggling over how such a widely international platform like the Apple iPhone can prohibit this. i.e., if my app were a Chinese game of Go, am I not all...
Distributing a small PHP application
I wrote a small PHP application that I'd like to distribute. I'm looking for best practices so that it can be installed on most webhosts with minimal hassle. Briefly: It's simple tool that lets people download files once they login with a password. So my questions are: 1) How should I handle configuration values? I'm not using a datab...
Do you use a different app id for your iPhone beta apps?
Those of us with iPhone apps (released or unreleased) are able to send out limited beta builds using ad-hoc distribution. While the Apple docs for this have a few holes in them, there are a number of blogs, postings and other articles out there on "the net" that fill the gaps. However, one thing I haven't seen anyone mention, and I was ...
Creating an Eclipse "Distribution"?
In the context of creating a custom Eclipse distribution for a development team. How would I go about building a custom Eclipse distribution containing a specific set of plugins? Would it be difficult to also add a kind of update site to put specific versions of the plug-ins from which the customized eclipse would update? ...
Putting separate python packages into same namespace?
Hey everyone, I'm developing a python framework that would have "addons" written as separate packages. I.e.: import myframework from myframework.addons import foo, bar Now, what I'm trying to arrange is so that these addons can be distributed separately from core framework and injected into myframework.addons namespace. Currently my...
ASP.NET Web App Distribution
What is the simplest way to distribute an asp.net web application? I tried to look at some of the open source asp.net projects out there to see how they distribute their apps and how they do updates and they seem rather complicated to me (not for myself to perform but for non-technical users). A lot of them entail backing up the entire i...
How do I distribute my slightly customized Linux in VirtualBox?
Suppose I've got some Arch Linux installation which I'd like to distribute among students with (sometimes very) basic Linux knowledge to make them able to compile C programs in an environment very similar to that in the university. (Things like Cygwin or MinGW seem to be inappropriate here.) I also choose VirtualBox as a holder for the ...
Probability distribution in Python
I have a bunch of keys that each have an unlikeliness variable. I want to randomly choose one of these keys, yet I want it to be more unlikely for unlikely (key, values) to be chosen than a less unlikely (a more likely) object. I am wondering if you would have any suggestions, preferably an existing python module that I could use, else I...
Can we publish two versions of an iphone application?
HI, I am developing an application for an esteemed client in Australia. They have certain copyright issues when it comes to uses outside Australia accessing the content via the app. Is it possible to have a local and an international version of the app, both available via iTunes Store? The international version will only have permissib...
Using Maven for project distribution
I have an Project that I distribute by sending out large packages. I'd like to know if there is a user friendly way of using Maven to distribute updates of the project? I'd need something like what is done for updating softwares like Firefox or Acrobat Reader. Check a respository, warn user of an update, download and reconfigure. All wit...
When is it (not) appropriate to bundle dependencies with an application?
Summary I recently had a conversation with the creator of a framework that one of my applications depends on. During that conversation he mentioned as a sort of aside that it would make my life simpler if I just bundled his framework with my application and delivered to the end user a version that I knew was consistent with my code. I...
iPhone: Can a dev other than team agent build an app for distribution
Hello, I have a company iphone dev account. According to the doc, only the team-agent is allowed to submit a distribution cert and download the distribution provisioning profile. Can a team only have 1 Team Agent? Also, if that is the case, is there a way around this to allow multiple devs the option to build a distributed version o...
