The web shop where I work we do both .Net and PHP/Linux development. We'd like to start automating a lot more of our deployment processes using a common system that can be used for both. What would you recommend as a good common scripting language or automation system (like Ant or Maven) that works well for both .Net and Linux development?
I have no experience with Maven, but we've managed to get Ant to do everything we've wanted on multiple platforms, just by virtue of the fact that you can extend it with any Java program to do special tasks not included with the Ant application itself.
And then Java can, if necessary, call any external program you want to by using Runtime.exec(). Loses a bit of the portability but it was required for some command-line tools under both Linux and Windows.
You may want to see how Perl does cross platform automation. The design for Perl6, seems to be a bit better designed, but the Perl5 design has had many years to develop.
Perl has been ported to many different platforms, not just Linux and Windows.
You may get some mileage out of Capistrano. It is rails centric but it is pretty general purpose, and I believe it has been extended to do other things also. Not sure how well it plays with Windows and .NET, but worth a look.
You can develop .net on linux using Mono.
On that linux server you can use both .net and php.

I am developing an Outlook plugin solution that involves the plugin itself and a windows application working in tandem.
The plugin targets multiple versions of Outlook - 2007, 2010 and 2013.
The windows app uses different libraries for x86 and 64 bit processors.
Of course there are dependencies of both the plugin and the app.
In addition to pure installation, I would like to make automatic updates possible. It could be something as simple as custom code in the windows app to check for updates in a predefined location. But I would like to know my options.
The solution I have in mind right now, and which I would like to ask the SO community to evaluate is as follows:
Separate Windows Setup Projects (producing MSI files) for each combination of application and configuration (This could be as many as 8 different msi files)
One common bootstrapper project, detecting current system configuration and installing prerequisites and selected msis.
MSIs would not have prerequisites embedded in them, only the uber-installer/bootstrapper would have those.
Am I missing something? Is this solution viable? Are there third party alternatives to Windows Setup Projects that would make my life easier? Full featured Install Shield maybe?
In case this actually is helpful for someone, the solution I went with is the incredibly customizable installer solution: InstallMate 7 by Tarma.
You can find out more from their website, but the features that got me are:
Built in support for x86 and x64
Customizable prerequisites
Stand-alone update tool also provided by Tarma, which simplifies
automatic updates a lot.
PRICE! Forget about spending 5K on similar features elsewhere.
I am an ASP.NET developer, but now I want to build a software that can be installed on my PC. Software built in .NET platform only works when the .NET Framework is installed, and software written in Java only works if the JDK is installed. When I install programs like Firefox, uTorrent, etc., I don't need to have any frameworks (.NET, JDK, etc.) installed. How do I write software that doesn't depend on a framework?
You will have to use a language that isn't dependent on a framework or otherwise only target clients that are already have your framework installed.
If you chose C or C++ for example, you would distribute binaries to your client that contained machine code. This code would not be dependent on a runtime environment (like C# or Java) or an interpreter (like Python or Ruby). This is the way that applications like Firefox and uTorrent are written.
"When I install programs like Firefox, uTorrent, etc., I don't need to have any frameworks."
Actually, you do. They just tend to use the C++ frameworks, such as MFC, some of which are already installed. Even then, there are installers for these frameworks that are included with other application installers (usually called Microsoft Visual C++ 2008 SP1 Redistributable Package or something like that. See Also: Visual C++ Deployment).
Now, having said that, they don't require a virtual machine (like a JVM for Java or a CLR for .NET), because C++ compiles down to x86 / x86-64 machine language to be executed directly by the operating system.
Fundamentally you always have a "platform", which is the operating system. Traditionally if you want to write code that will run on multiple operating systems you would use a fairly portable language such as C++ that produces native executables for a target operating system. Still, there are differences between how different operating systems work. There will therefore be parts of the C++ (or other portable language) code that are specific to that OS. You try to isolate those parts as much as possible to minimize the effort to port between OSes. Still, that effort is typically very substantial. You are also limited to the least common denominator of features available on all target operating systems (unless you create a custom version for a given OS that exposes its special features).
This is complex, time consuming and expensive. That's the reason technologies such as Java and .NET were created.
If You want to build really platform independent software You will finally end up with solution like Java Runtime or .NET. What You could do, You could thing about writing application in such way that You are able to compile/run it on most known platform, and of course then You need middleware to translate Your application's objects into platform objects (functions, whatever...).
I have seen solutions made in Pascal for DOS in such layer of abstraction that with little effort it was moved directly to Delphi for Windows without touching application logic.
I had developed web applications under environment mod_perl + Apache + Linux.
Now, I want to deploy a web application solution to my client, under Windows.
I was wondering any problem you guys encounter, when running mod_perl + Apache + Windows?
(1) Can I get Perl additional library (CPAN?), and being used in my web application easily? "Easily" means, no manual compilation. No complex configuration setup.
(2) How about Linux command feature? Perl integrate well with Linux utility to perform certain tasks. But if come to Windows, does it able to offer the similar features as in Linux's?
I am open to other web development environment under Windows (PHP or Python). The reason I choose Perl, as I know the language. I just do not want to switch to other language without a good reason.
I have not use mod_perl but for your question 1, you can take a look at the installation docs. . I have used Activestate Perl and PPM before and using ppm to install modules is easy.
for (2), Perl is a programming language and it comes with builtins and modules to do what *nix tools do, so there should be no problem. (there is no need to make calls to use *nix tools unless really necessary). Always check CPAN/PPM to see if there are modules to do what you want.
Personally, I prefer PHP if i am doing web programming because its easy to setup and lots of nice features already done specifically for web programming.
First of all I love Eclipse but I'm not satisfied with its performance in Linux (Ubuntu) - It is CPU intensive and not responsive enough.
My question is if there is an IDE with most of Eclipse's functions but not built in Java. (More than a Notepad, but not a command line tool like vi or emacs).
Update: I'm looking for an IDE that I could use for Java, PHP, and Python development.
There's KDevelop, a QT4 based IDE that works on all platforms for C++ development. MonoDevelop is a .NET IDE for Linux & other platforms. Komodo, a commercial option, is available for Linux and works well. It's not built with Java, so you will save several MB of RAM allocation. :) It's fast. wxStudio is an interesting option, if you choose to use the wxWindows libraries. There's also Code::Blocks for C++ work. Sun even provides NetBeans, which has plugs-ins like Eclipse for other languages, yet runs a tad faster than Eclipse.
It really depends on the language you're developing in. Honestly, the majority of IDE features you're likely seeking are already natively available in Vim & Emacs... code completion, jumping to definition, breakpoints, etc. are Vim specialties. If you really want a GUI, then the languages you're using are a really important factor.
Does anyone know of a good software development framework or similar that has the following properties?
Cross platform: it should be runnable on XP, Vista, OSX and common versions of Linux (such as Ubuntu and Kubuntu).
No installation: Be able to run the software from a USB stick without having to copy anything to the host machine.
Have good GUI support (this is why this question doesn't give a suitable answer, as far as I can tell).
Permissive licensing such as LGPL or BSD or such.
Among the softer requirements are having a set of abstractions for the most common backend functionality, such as sockets, file IO, and so on (There is usually some platform specific adaptations necessary), and supporting a good language such as Python or C++, though it is usually fun to learn a new one (i.e. not perl).
I think possible candidates are Qt 4.5 or above (but IFAIK Qt software will not run on Vista without any installation(?)), some wxWidgets or maybe wxPython solution, perhaps gtkmm. The examples I have found have failed on one or another of the requirements. This does not mean that no such examples exist, it just means that I have not found any. So I was wondering if anyone out there know of any existing solutions to this?
Some clarifications;
By "framework" I mean something like Qt or gtkmm or python with a widget package.
This is about being able to run the finished product on multiple platforms, from a stick, without installation, it is not about having a portable development environment.
It is not a boot stick.
It is ok to have to build the software specifically for the different targets, if necessary.
The use case I am seeing is that you have some software that you rely on (such as project planning, administration of information, analysis tools or similar) that:
does not rely on having an internet connection being available.
is run on different host machines where it is not really ok to install anything.
is moved by a user via a physical medium (such as a USB stick).
is run on different operating systems, such as Windows, Vista, Ubuntu, OSX.
works on the same data on these different hosts (the data can be stored on the host or on the stick).
is not really restricted in how big the bundled framework is (unless it is several gigabytes, which is not really realistic).
It is also ok to have parallel installations on the stick as long as the software behaves the same and can work on the same data when run on the different targets.
A different view on the use case would be that I have five newly installed machines with Vista, XP, OSX, Ubuntu and Kubuntu respectively in front of me. I would like to, without having to install anything new on the machines, be able to run the same software from a single USB stick (meeting the above GUI requirements and so on) on each of these five machines (though, if necessary from different bundles on the stick).
Is this possible?
Edit:
I have experimented a little with a Qt app that uses some widgets and a sqlite database. It was easy to get it to work on an ubuntu dist and on osx. For windows xp and vista I had to copy QtCored4.dll, QtGuid4.dll, QtSqld4.dll and mingwm10.dll to distribution directory (this was debug code) and I copied the qsqlited4.dll to a folder named "sqldrivers" in the distribution directory.
You mention wxWidgets but dismiss it as failing at least one of the requirements.
I don't know what your requirements are and in what way wxWidgets wouldn't work for you, but IMO it does fulfill them:
Cross platform: it should be runnable on XP, Vista, OSX and common versions of Linux.
It does run on those platforms, but "common versions of Linux" isn't good enough, as you can never be sure that the necessary GUI libraries for wxGTK (which should not be linked to statically) will be installed. This is however a problem for other solutions as well, unless you plan to put everything onto the stick.
No installation: Be able to run the software from a USB stick without having to copy anything to the host machine.
See the previous point, you would need to specify which libraries are needed on Linux. Also you could specify at build time not to use some of the system-provided libraries (for example for graphics, compression, regexes) but to use the wxWidgets-internal libraries instead.
Have good GUI support
Check.
Permissive licensing such as LGPL or BSD or such.
Check. You can statically link wxWidgets into your application too.
supporting a good language such as Python or C++
Supports both, and there are bindings to other languages as well.
having a set of abstractions for the most common backend functionality, such as sockets, file IO, and so on
It does have some abstractions like that, but you can link to other cross-platform libraries as well.
We use wxWidgets for FlameRobin, a graphical administration program for the Firebird SQL server. It has active ports to Windows, Linux and Mac OS X, and has been compiled for at least some BSD variant and Solaris as well. It definitely runs from a stick on Windows, I haven't tried with Linux or Mac OS X, but I don't see why it shouldn't there too.
Java.
It has GUI support.
It provides your network/file/etc. abstractions.
It is cross-platform. Most platforms you can think of have a JRE available.
No need to install a JRE. Most users probably already have one, and if not, you can run the appropriate JRE right off the stick.
You can provide several startup scripts for various platforms to run the app under the appropriate JRE.
Something else to consider is HTML+Javascript. :D
You can look at Mono it cross platform, has GUI (GTK+, or Winforms 2.0) and I can execute code without installing.
This might not be crossplatform, but is maybe even better, it dont even use the platform : linux on a stick :-)

Well, it depends on what you mean by 'package'. Kylix came close to being such a thing. It was QT based, and it allowed you to write once and compile for Windows + Linux. However, it was not an open source solution.
I asked a similar question in this link
http://www.24hsoftware.com/DevelopersForum/CrossPlatform-C-Library.html
and the best asnswer seems to be QT.
I have started using QT, but it is not as easy as I expected mainly due to deployment problems due to the DLL hell, Winsxs hell and manifest hell.
Tclkit is a single-file, self-contained Tcl/Tk system. The mac version I have is about 3.8 megs. You can get a version for just about any modern OS. I carry around a thumb drive that has mac, windows and linux binaries so I can run my scripts on any platform. No install is required, just copy one file wherever you want.
The most recent versions of tcklit use native, themed widgets (though, on *nix there really isn't a single "native" set of widgets...)
