A Dev Environment for the Returning Geek?
InsurgentGeek asks: "I'm about 25 years into my career in technology. Over that time, I've done the standard progression from developer to architect to team leader to program leader to business unit leader. While I've stayed up to date on general technology trends (perhaps more than about 95% of my peer group) - I have started to really miss hands on coding - something I haven't done for almost 20 years. It's not for my job, and I don't plan to make any money at it - but I'd like to get back to coding on at least a recreational basis. Here's the rub: what are the right tools?"
"'Back in the day...' you had about 2-3 choices of languages and perhaps the same number of OS's. There were not frameworks, API's, development environments, etc. I'd like to pick a toolkit and learn it. My goals are pretty simple: I want to write applications that have a great look & feel that will primarily be pulling information from the web (think weather & news), play with that information and present it in interesting ways. I'd like those applications to be usable on the Linux and perhaps Mac OS X platforms. I'm not a complete non-techie. I use Linux at home, have set up all the toys like Squid and BIND - but this is just administration. I need to get back into the guts of the machine. If you were me where would you start? What language(s) would you want to become conversant in? What do I have to worry about beyond the choice of the language itself? What frameworks? What other tools?"
You don't really say what type of problems you want to work on and that can make a big difference in what environment you choose. Kernel hacking leads in one direction, and DB-driven websites goes in a completey different direction.

Speaking as a GeezerGeek(tm), here are some of the technologies I have found that are something more than The Next Great Thing ver 31.4.
1. Python. It took me a while to get past the indentation-as-block-structure thing (I still think it was a mistake), but this is a language that tremendous expressive power. If I were still teaching, this is the language I would start my students with, knowing that they could go anywhere they want with it.
2. If you are doing any sort of web work, you will probably have to do a little (a lot?) PHP. Fortunately, v. 5 has fixed some of the nastier aspects of the language, although there appears to be no way to undo some truly horrible naming convention mistakes from its early days.
3. AJAX. It's worth a look if you want to stay within the browser's window. And that means you should get good Javascript/CSS/XML/HTML books.
4. Firefox-as-UI-platform. This is related to the above. I am just beginning to get into this and it looks very promising. Other people know far more than I do. The GreaseMonkey extension is great fun to play with.
5. If you are picking up a DBMS, the obvious choices are MySQL and Postgres. If I were just starting, I think I would go with Postgres, if only for OSS purity reasons. OTOH, I have had no problems with MySQL for the relatively low-level situations I have used it and it is generally more available as part of commercial hosting packages.
"Back in the day" I taught programming, so here are a few recommendations for your first few projects.
A. First, pick something fun and relatively simple. I have found that a great way to get into a new language/platform environment is to implement a simple game (eg. hangman, snake, mastermind). The rules are very straightforward, yet they will force you to at least dip your mental toe into logic flow, class structure, I/O and UI, file storage (for high scores), etc. Most of them can be implemented in a few hours and you get that immediate feedback of success. If you are feeling your oats, you might try things like using Python's generators as nanothreads for animation sprites. See the Lightweight Games Toolkit at http://lgt.berlios.de/ for some ideas. (Obviously, this should *not* be for your first project!
B. Pick an area of application that you are already a domain expert in. This way you can focus on the "how", instead of the "what" or the "why".
C. Find a good OSS project and implement a few new features. For example, if you are interested in photography, you might grab Gallery 2 from gallery.menalto.com and try adding a feature to an existing layout module, or try creating a new layout, using an existing one as a template.
D. Find an interesting-but-broken OSS project and dive into the code. Maybe you can breathe new life into a moribund project.
