shifting from windows to *nix programming platform

Question

How to migrate to *nix platform after spending more than 10 years on windows? Which flavor will be easy to handle to make me more comfortable and then maybe I can switch ove

Answer 1

Linux is the most accessible and has the most mature desktop functionality. BSD (in its various flavours) has less userspace baggage and would be easier to understand at a fundamental level. In this regard it is more like a traditional Unix than a modern Linux distribution. Some might view this as a good thing (and from certain perspectives it is) but will be more alien to someone familiar with Windows.

The main desktop distributions are Ubuntu and Fedora. These are both capable systems but differ somewhat in their userspace architecture The tooling for the desktop environment and default configuration for system security works a bit differently on Ubuntu than it does on most other Linux or Unix flavours but this is of little relevance to development. From a user perspective either of these would be a good start.

From a the perspective of a developer, all modern flavours of Unix and Linux are very similar and share essentially the same developer tool chain. If you want to learn about the system from a programmer's perspective there is relatively little to choose.

Most unix programming can be accomplished quite effectively with a programmer's editor such as vim or emacs, both of which come in text mode and windowing flavours. These editors are very powerful and have rather quirky user interfaces - the user interfaces are ususual but contribute significantly to the power of the tools. If you are not comfortable with these tools, this posting discusses several other editors that offer a user experience closer to common Windows tooling.

There are several IDEs such as Eclipse that might be of more interest to someone coming off Windows/Visual Studio.

Some postings on Stackoverflow that discuss linux/unix resources are:

• What are good linux-unix books for an advancing user

• What are some good resources for learning C beyond K&R

• Resources for learning C program design

If you have the time and want to do a real tour of the nuts and bolts Linux From Scratch is a tutorial that goes through building a linux installation by hand. This is quite a good way to learn in depth.

For programming, get a feel for C/unix from K&R and some of the resources mentioned in the questions linked above. The equivalent of Petzold, Prosise and Richter in the Unix world are W Richard Stevens' Advanced Programming in the Unix Environment and Unix Network Programming vol. 1 and 2.

Learning one of the dynamic languages such as Perl or Python if you are not already familiar with these is also a useful thing to do. As a bonus you can get good Windows ports of both the above from Activestate which means that these skills are useful on both platforms.

If you're into C++ take a look at QT. This is arguably the best cross-platform GUI toolkit on the market and (again) has the benefit of a skill set and tool chain that is transferrable back into Windows. There are also several good books on the subject and (as a bonus) it also works well with Python.

Finally, Cygwin is a unix emulation layer that runs on Windows and gives substantially unix-like environment. Architecturally, Cygwin is a port of glibc and the crt (the GNU tool chain's base libraries) as an adaptor on top of Win32. This emulation layer makes it easy to port unix/linux apps onto Cygwin. The platform comes with a pretty complete set of software - essentially a full linux distribution hosted on a Windows kernel. It allows you to work in a unix-like way on Windows without having to maintain a separate operating system installations. If you don't want to run VMs, multiple boots or multiple PCs it may be a way of easing into unix.

Answer 2

Try Kubuntu as a distro and Kdevelop and Qt to start programming with, it's all very civilised.

Kate's an ok notepad-esque text editor if you want to go that way but I don't see why you'd want to get in to Vi or Emacs apart from the geeky appeal of using something really arcane.

Answer 3

Any modern version of Unix (or Linux) you can get running on your machine will be fine.

Here are the ones that I would consider:

• Ubuntu. As others have noted, this is often considered to be the easiest to use. However some parts are not "standard" Unix. For example, the startup scripts do not use init. This is mostly a good thing, but if you're trying to learn Unix may not be what you need.
• Fedora. Bleeding edge but with rough edges.
• Slackware. Possibly the most Unix-like Linux distribution (some would say dated!).
• One of the *BSDs: FreeBSD, OpenBSD, NetBSD. Different approach to some things than Linux.
• Solaris. This is "proper" Unix. Seems bare-bones compared with Linux but worth playing with to see what's "standard."

In fact, I would consider running at least a couple of them, most run fine as a VM. One of the good and bad things about Unix is that what's standardised is more the philosophy than many of the details. There's no Visual Studio, there's no C# (by that I mean no canonical high level language; I know about Mono).

Answer 4

Get a macbook pro. OSX is the smoothest flavour of unix and the laptop should give you the push you need.

Then when you're feeling more confident, you can decide whether or not you want to spend most of your time configuring your soundcard, running ./autoconfigure && make, and debugging package manager screwups.

Answer 5

I guess it also depends on what programming languages your are comfortable with.

If you worked with C# in the past then you could look at using the knowledge by running Mono , or maybe look at using Java (which is syntactically very similar). Either way Linux would be good.

I personally would recommend you look at the Mac's OS X. Its a unix BSD based OS, but with a really slick user interface over the top. To me it feels like the best of both the Windows and Unix worlds.

I do all my unix development on it, deploying onto Ubuntu servers. If you do look at a Mac, definitely take a look at the MacPorts project, which packages a large amount of the open source unix/linux software up making installation of programming tools incredibly easy.

Answer 6

Ubuntu is nicely balanced, with a user friendly desktop but the potential to set up a fully functional programming environment.

I would advise experimenting with virtual machines - there is no reason to ditch your current setup until you've tried a few of the major distributions. VMware and others have a wide variety of server and desktop builds available.
