I'm trying to find a modern environment similar to what I found great about QBasic but making up for the flaws. The purpose of this is to code with my 6 year old son.
I'm looking for an IDE that uses a modern language, has the ability to draw graphics and play audio, and doesn't force the User to jump around much between coding and running their application.
In QBasic you had basically two modes: Edit and Run. There were no third party libraries required for creating graphics or generating Audio tones (that I remember). You never had more than one "window" opened at a time.
Is there a modern day equivalent IDE which uses a modern language that provides what I'm looking for?
I don't want him to have to jump around between various windows, try to wrap his mind around window toolkits, understand the command line, or use OOP just to get started. My end goal is to create simple graphical games with him -- not printing text out to the console.
(Preferably cross platform or useable on Mac OSX since that's what we have at the house. Preferably Python based since that's my language of choice.)
QBasic is a great option. You can purchase an old PC from a thrift store and run QBasic on it. There is the option of QB64 which can run on both Mac and Windows. Hope this is helpful.
I'd suggest QB64, almost 100% compatible with QBasic/QuickBasic but runs on Windows.
You could maybe try Small Basic, it aimed to recreate the ease-of-use and educational purposes of the old BASIC languages build into home computers from the 1980s
The Small Basic project was initiated following this article on Salon:
Why Johnny can’t code (David Brin, 2006)
I work on windows and I need a very simple version track software to be able to check in/out a folder project, no matter what's inside. I downloaded few programs, but most of them are very complicated, team work, cloud, thousands of options, etc.
I need some simple version track of my files, locally. Can you recommend me something useful?
i'd recommend using simpy rar with datetime. Or as an option - just parameter to update archive instead of creating new one
There are a number of reasons why version control software have the number of options that they do, without understanding the basics of how the particular version control system that you are trying to use functions these options can seem overwhelming. To be able to use version control you will have to put in a little bit of effort to understand how it works. That being said I find that Bazaar from Canonical makes a pretty good introduction to version control for beginners. It has a pretty nice download page for various platforms and comes with a GUI client and comes with beginner friendly documentation.
However, having used other version control systems I personally don't like to use Bazaar. The choice of version control system should not make a difference if you are only looking to use it yourself and don't need any of the more advanced features. If you are willing to invest some more time however, I would recommend trying Mercurial it has some documentation for beginners and a fairly nice beginner friendly GUI for Windows in the form of EasyMercurial.
What is the best route or place to get started with arcobjects if one is not a developer and not aiming to become one?
I've been using gis professionally for a long time, almost two decades, arcinfo/arcgis for most of that; I'm pretty good. I'm learning software development, and even have a modestly successful small python application used in a public project; I'm not good! I don't want to become a full fledged software developer but I keep running into things I just can't do without programming (example). In the arcgis world this puts me pretty squarely in the python camp, which is fine by me since I like python, however python does not have straightforward access to arcobjects.
Soooo, I need to get started, but where? Arcgis help says to get started with the ESRI Developer Network but $1500/yr is definitely not in my budget, and sounds like using a sledge hammer to swat mosquito. And which language .NET, Visual Basic, or Visual C++?
Thanks for your thoughts.
Assuming you have desktop, I'd just install the SDK from the desktop installation DVD's and download the free VS2010 60 day eval (which can be extended).
VS Express is supported, but I've never used it.
For language, I'd stay away from C++. There's more sample code available for C# than VB.NET. Except for the yield keyword, VB.NET and C# are equal.
I've got a game in VB6 and it works great and all, but I have been toying with the idea of creating a scripting engine. Ii'm thinking I'd like VB6 to read in flat text script files for me and then lex/parse/execute them.
I have good programming experience, and I've built a simple C compiler, as well as a LOGO emulator before.
My question is:
Are there any tools that I can use, like Lexx/Yakk/Bison to help me? How should I approach this problem in regards to lexing, parsing, and feeding the commands back to VB6 so I can handle them? Is this idea a BAD IDEA in the sense that there are too many obstacles in the way (For example, building minesweeper in assembly, though not impossible, is very difficult, and a bad idea.)?
Use the Microsoft® Windows® Script Control because it is easy to integrate into existing VB6 applications. The control supports VBScript, JScript, or any other "Active Script" implementation.
I have used the Windows Script Control in four projects and it works extremely well. Very easy to integrate. I wish Microsoft would have given us a replacement in .NET, and made it as easy to use. (I understand the control is not needed in .NET, but having the ability to simply create an object that handles everything is nice.)
Windows Script Control
The Microsoft® Windows® Script Control
is an ActiveX® control that provides
developers with an easy way to make
their applications scriptable. This,
in turn, enables users to extend
application functionality through
scripts, much as they do with macros
today.

Unless you're doing it for your own instruction, you may want to try using Lua: VB6 - Lua Integration
If you're willing to use VBScript rather than VB6 you might be able to just use the MSScriptControl to run the commands rather than creating your own. Here's an article discussing using it from a .Net app, though it's an ActiveX control so should give you quite a bit of flexibility.
The control can be downloaded from here.
I've actually seen some quite reasonable implementations of compilers/interpreters in VB6[1] - It's not the language I would choose (few functional features, insufficent static type system), but with experience, you can outweigh these drawbacks and be quite productive - So why not.
You can use the GOLD parser generator that supports VB6 as a start.
[1]: Somewhere on PSC or in this download repository I think ...
Note that there is the MSScriptControl too.
There also appears to be an additonal alternative for VB6:
SadScript is an variant of VB6 most prominently used for VB6 as an scripting engine in MMORPGS .
See here for more : What is sadscript? Can I use it in vb.net? Why hasn't anyone I have asked heard of it?
As already discussed in "Lua as a general-purpose scripting language?" Lua currently probably isn't the best scripting language for the desktop environment.
But what do you think about the future? Will Lua get so popular that there will soon be enough libraries to be able to use it like Python, Ruby or something similar?
Or will it simply stay in it's WoW niche and that's it?
I think it has a great future, a lot of projects are starting to adopt it for it's simplicity and usefulness.
Example: Awesome WM (Window Manager)
The project recently released version 3, incorporating a new configuration system completely written in Lua. Allowing you to literally write your configuration file as a program, loops, booleans, data structures.
Personally I love the syntax and the flexibility of such a system, I think it has great potential.
I wouldn't be surprised if it became more popular in the future.

I suppose the answer starts with 'It depends how you want to use it...'.
If you're writing the common business app (fetch the data from the database, display the data in a web page or window, save the data to the database), Lua already has what you need.
The Kepler Project contains goodies for web development. Check out their modules to see some of the available libraries - there's network, MVC, DBMS access, XML, zip, WSAPI, docs...
As an example web app, check out Sputnik.
For desktop UI, there's wxLua - Lua hooks for wxWidgets.
ORM is conspicuously missing but that didn't stop people from developing in other languages before ORM was available.
If you're looking for specialized libraries - scientific, multimedia , security - don't count Lua out before you check LuaForge.
When it comes down to it, there's nothing in Lua's design that prevents general purpose use. It just happens to be small, fast, and easy to embed... so people do.
Uh? I would say instead WoW is a niche in the Lua ecosystem... The world of Lua doesn't revolve around WoW, there are lot of applications, some big like Adobe Lightroom (to take a non game), using Lua.
Lua is initially a scripting language, in the initial sense, ie. made to be embedded in an application to script it. But it is also designed as an extensible language, so we will see progressively more and more bindings of various libraries for various purposes.
But you will never get an official big distribution with batteries included, like Python or Perl, because it is just not the philosophy of the authors.
Which doesn't prevent other people to make distributions including lot of features out of the box (for Windows, particularly, where it is difficult to build the softwares).
Lot of people already use it for general system-level scripting, desktop applications, and such anyway.
There are more and more libraries for Lua.
If you are a Windows user, have look at Lua for Windows. It comes with "batteries included" (wxLua, LuaCURL, LuaUnit, getopt, LuaXML, LPeg...).
Very usefull!
It's 2017, 9 years after this question was first asked, and lua is now being heavily used in the field of machine learning due to the Torch library.
I really like it as an embedded language. It's small, very easy to use and embed and mostly does what I need right out of the box. It's also similar enough to most languages that it has never really been an issue for me. I also like how easy it is to redefine and add base functions and keywords to the language to suit whatever needs my application has.
I have used it in the WoW area but I've also found it useful as a generic scripting language for a number of different applications I've worked on, including as a type of database trigger. I like Ruby and Python and other more full-featured scripting languages but they're not nearly as convenient for embedding in small applications to give users more options for customizing their environments.
being comfortable as a shell language has nothing to do with being a great general purpose language.
i, for one, don't use it embedded in other applications; i write my applications in Lua, and anything 'extra' is a special-purpose library, either in Lua or in C.
Also, being 'popular' isn't so important. in the Lua-users list periodically someone appears that says "Lua won't be popular unless it does X!", and the usual answer is either: "great!, write it!", or "already discussed and rejected".
I think the great feature of Lua is, that it is very easily extensible. It is very easy to add the Lua interpreter to a program of your own (e.g. one written in C, C++ or Obj-C) and with just a few lines of code, you can give Lua access to any system resource you can think of. E.g. Lua offers no function to do xxx. Write one and make it available to Lua. But it's also possible the other way round. Write your own Lua extension in a language of your choice (one that is compilable), compile it into a native library, load the library within Lua and you can use the function.
That said, Lua might not be the best choice as a standalone crossplatform language. But Lua is a great language to add scripting support to your application in a crossplatform manner (if your app is crossplatform, the better!). I think Lua will have a future and I think you can expect that this language will constantly gain popularity in the long run.
Warhammer Online, and World of Warcraft use it for their addon language I believe.
I think it's hot! I'm just no good at it!
Well, greetings from 2022.
It is already a general purpose language. Today you can even serve pages using OpenResty, extend games, read databases or create scripts as shellscript replacements.
There are a plenty of libraries "modules" for Lua, many ways to achieve what you are wanting and Lua 5.4 is even faster.
The "extendable and extensive" nature of Lua, accostumed people to think it should only be used as plugin or extension. In Linux, by example, you can shebang a file with lua-any, make it executable and run like any system script. Or you can make a folder app like Python or virtualenv using Lupe. Lua 5.3 also gained impressive performance improvements.
Also there are many good tools like IUP to create native windows in Lua for Mac, BSD, Linux and Windows and side environments like Terra that lets you use Lua with its counterpart Terra and write compiled programs. Lua now, is more than a extension language, it has its own universe.
