Using the right language for the job is the key - this is the comment I read in SO and I also belive thats the right thing to do. Because of this we ended up using different languages for different parts of the project - like perl, VBA(Excel Macros), C# etc. We have three to four languages currently in use inside the project. Using the right language for the job has made it immensly more easy to do automate a job, but of late people are complaining that any new person who has to take over the project will have to learn so many different languages to get started. Also it is difficult to find such kind of person. Please note that this is a one to two person working on the project maximum at a given point of time. I would like to know if the method we are following is right or should we converge to single language and try to use it across all the job even though another language might be better suited for it. Your experenece related to this would also help.
Languages used and their purpose:
Perl - Processing large text file(log files)
C# with Silverlight for web based reporting.
LabVIEW for automation
Excel macros for processing data in excel sheets, generating graphs and exporting to powerpoint.
I'd say you are doing it right. Almost all the projects I've ever worked on have used multiple languages, without any problems. I think you may be overestimating the difficulty people have picking up new languages, particularly if they all use the same paradigm. If your project were using Haskell, Smalltalk, C++ and assembler, you might have difficulties, I must admit :-)
Using a variety languages vs maintainability is simply another design decision with cost-vs-benefits trade-offs that, like any design decision, need to considered carefully. While I like using the "absolute best" tool for the task (whatever "absolute best" means), I wouldn't necessarily use it without considering other factors such as:
do we have sufficient skill and experience to implement successfully
will we be able to find the necessary resources to maintain it
do we already use the language/tech in our system
does the increase in complexity to the overall system (e.g. integration issues, the impact on build automation) outweigh the benefits of using the "absolute best" language
is there another language that we already use and have experience in that is usable in lieu of the "absolute best" language
I worked a system with around a dozen engineers that used C++, Java, SQL, TCL, C, shell scripts, and just a touch of Perl. I was proud that we used the "best language" where they made sense, but, in one case, using the "best language" (TCL) was a mistake - not because it was TCL - but rather because we failed to observe the full costs-vs-benefits of the choice:*
we had only 1 engineer deeply familiar with TCL - the original engineer who refused to use anything but TCL for a particular target component - and then that engineer left the project
this target component was the only part of the system to use TCL and it was small relative to the other components in the system
the component could have been also implemented in another language we already used that we had plenty of experience in (C or C++) with some extra effort
the component appeared deceptively simple, but in reality had subtle corner cases that bit us in production (not something we could have known then, but always something to consider as a possibility later)
we had to implement special changes to the nightly build because the TCL compiler (yes, we compiled the TCL code into an executable) wouldn't work unless it could first throw its logo up on the screen - a screen which wasn't available during a cron-initiated automated nightly build. (We resorted to using xvfb to satisfy it.)
when bugs turned up, we had difficult time finding engineers who wanted to work on it
when problems with this component cropped up only after sustained load in the field, we lacked the experience and deep understanding of the TCL execution engine to easily debug it in the field
finally, the maintenance and sustainment team, which is a much smaller team with fewer resources than the main development team, had one more language that they needed training and experience in just to support this relatively small component
Although there were a number of things we could have done to head-off some of the issues we hit down the road (e.g. put more emphasis on getting TCL experience earlier, running better tests to detect the issues earlier, etc), my point is that the overall cost-vs-benefit didn't justify using TCL to code that single component. Again, it was not a mistake to use TCL because it was TCL (TCL is a fine language), but rather it was a mistake because we failed to give full consideration to the cost-vs-benefits.
As a Software Engineer it's your job to learn new languages if you need to. I would say you should go with the right tool for the job.
It's like sweeping the floor with an octopus. Yeah, it gets the job done... kind of... but it's probably not the best tool for the job. You're better off using a mop.
Another option is to create positions geared towards working in specific languages. So you can have a C# developer, a Perl developer, and a VBA developer who will only work with that language. It's a bit more overhead, but it is a workable solution.
Any modern software project of any scope -- even if it's a one-person job -- requires more than one language. For instance, a web project usually requires Javascript, a backend language, and a DB query language (though any of these might be created by the backend language). That said, there's a threshold that is easily reached, and then it would be very hard to find new developers to take over projects. What's the limit? Three languages? Four? Let's say: five is too many, but one would be too few for any reasonably complex project.
Using the right language for the right job is definitely appropriate - I am mainly a web programmer, and I need to know server-side programming (Rails, PHP + others), SQL, Javascript, jQuery, HTML & CSS (not programming languages strictly, but complex things I need to know) - it would be impossible for me to do all of that in a single language or technology.
If you have a team of smart developers, picking up new languages will not be a problem for them. In fact they probably will be eager to do so. Just make sure they are given adequate time (and mentoring) to learn the new language.
Sure, there will be a learning curve to implementing production code if there is a new language to learn, but you will have a stronger team member for it.
If you have developers in your teams who strongly resist learning new languages, unless there is a very good reason (e.g they are justifiably adamant that they are being asked to used a different language when it is not appropriate to do so) - then they are not the sort of developers I'd want in my teams.
And don't bother trying to hire people who know all the languages you use. Hire smart programmers (who probably know at least one language you use) - they should pick up the other languages just fine.
I would be of the opinion, that if I a programmer on my team wanted to introduce a second (or third) language into a project, that there better be VERY VERY good reason to do so; as a project manager I would need to be convinced that the cost of doing so, more than offset the problems. And it would take a lot of convincing.
Splitting up project into multiple languages makes it very expensive to hire the right person(s) to take over that project when it needs maintenance. For small and medium shops it could be a huge obstacle.
Edit: I am not talking about using javascript and c# on the same project, I am talking about using C# for most of the code, F# for a few parts and then VB or C++ for others - there would need to be a compelling reason.
KISS: 'Keep it simple stupid' is a good axiom to follow in most cases.
EDIT: I am not completely opposed to adding languages, but the burden of proof is on the person to who wants to do it. KISS (to me) applies to not only getting the project/product done and shipped, but also must take into account the lifetime maint. and support requirements. Lots of languages come and go, and programmers are attracted to new languages like a moth to a light. Most projects I have worked on, I still oversee and/or support 5 or 10 years later - last thing I want to see is some long forgotten and/or orphaned language responsible for some key part of an application I need to support.
My experience using C++ and Lua was that I wrote more glue than actual operational code and for dubious benefit.
I'd start by saying the issue is whether you are using the right paradigm for the job?
Suppose you know how to do object oriented programming in C#. I don't think the leap to Java is all that great . Although you'd have to familiarize yourself with libraries and syntax, the idea is pretty similar.
If you have procedural parts to your project, such as parsing files and various data transformations, your Perl/Excel Macros seem pretty similar.
But to address your issues, I'd say above all, you'll need clarity in code. Since your staff are using several languages, they won't be familiar with all languages to an equal degree. So make sure of this:
1) Syntactic sugar is explained in comments. Sugars are pretty language specific and may not be obvious to a new reader. For instance, in VBA I seem to remember there are default properties, so that TextBox1 = "Hello" is what you'd write instead of TextBox1.Text = "Hello". This can be confusing. Also, things like LINQ statements can have un-obvious meanings. So make sure people have comments to read.
2) Where two components from different languages have to work together, make excruciatingly specific details about how that happens. For instance, I once had to write a C component to be called from Excel VBA. There's quote a few steps and potential errors in doing this, especially as far as compiler flags. Make sure both sides know how their side of the interaction occurs.
Finally, as far as hiring people goes, I think you have to find people who aren't married to a specific language. To put it vaguely, hire an intelligent person who sees business issues, not code. He'll learn the lingo soon enough.
The title may seem slightly self-contradictory, and I accept that you can't really learn a language quickly. However, an experienced programmer that already has knowledge of a few languagues and different styles (functional, OO, imperative etc.) often wants to get started quickly. I've seen a few websites doing effective "translations" in the form of "just show me syntax equivalence". I can't remember the sites now, but for related languages (e.g. Perl/PHP) it's quite common.
Is there a better resource that covers more languages? Is there a resource that covers idioms as well as syntax? I think this would be incredibly useful for doing small amounts of work on existing code bases where you are not familiar with the language. Looking at the existing code, as we know, is not always a good indicator of quality. Likewise, for "learn by doing" weekend project I always have the urge to write reasonably idiomatic, clean code from the start. Such a resource could also link to known good example projects of varying sizes for those that prefer to learn by reading. Reading a well-written medium sized code base can also be much more practical when access to development environments might be limited.
I think it's possible to find tutorials and summaries for individual languages that provide some of this functionality in disparate web locations but I'm hoping there is a good, centralised, comparative place that the busy programmer can turn to.
You generally have two main things to overcome:
Syntax
Reference
Syntax you can pick up fairly quickly with a language tutorial and a stack of samplecode.
Reference (library/API calls) you need to find a proper guide to; perhaps the language reference, or perhaps google...
With those two in place, following a walkthrough (to get you used to using the development environment) will have you pretty much ready - you'll be able to look up what you want to say (reference), and know how to say it (syntax).
This, of course, applies principally to procedural/oop languages; languages that require a paradigm switch (ML/Haskell) you should go to lectures for ;)
(and for the weirder moments, there's SO!)
In the past my favour was "learning by doing". So e.g. I know a little bit of C++ and a lot of C#.Net but I must write a FTP Tool in Python.
So I sit for an hour and so the syntax differences by a tutorial, than I develop the form itself and look at the generated code. Then I search a open source Python FTP Client and get pieces of code (Not copy and paste, write it self to see, feel and remember the code!)
After a few hours I get it.
So: The mix is the best. A book, a piece of good code, the willing to learn and a free night with much coffee.
At the risk of sounding cheesy, I would start with the language's website tutorial and/or FAQ, followed by asking more specific questions here. SO is my centralized location for programming knowledge.
I remember when I learned Perl. I was asked to modify some Perl code at work and I'd never seen the language before. I had experience with several other languages, however, so it wasn't hard to figure out the syntax with the online Perl docs in one window and the code in another, side-by-side. I don't know that solely reading existing code is necessarily the best way to learn. In my case, I didn't know Perl but I could tell that the person who originally wrote the code didn't know Perl either. I'm not sure I could've distinguished between good Perl and really confusing Perl. It would've been nice to be able to ask questions here at the time.
Language isn't important. What is important is learning your ways around designing algorithms and the proper application of design patterns. Focus on the technique, not the language that implements a certain technique. Once you understand the proper development techniques, any programming language will just become real easy, no matter how obscure they are...
When you put a focus on a language, you're restricting your own knowledge.
http://devcheatsheet.com/ seems to be a step in the right direction: it aggregates cheat sheets/quick references and they are (somewhat) manually reviewed. It's also wide-ranging. It still comes up short a bit in terms of "idiomatic" quick reference: for example, the page on Ruby doesn't mention yield.
Rosetta Code appears to be an excellent resource that includes hints on coding idiomatically and moves from simple (like for-loops) to things like drawing. I haven't checked out how comprehensive it is, but there are a large number of languages and tasks listed. The drawbacks re: original question are:
Some of the linking is not accurate
(navigating Python->ForLoop will
take you to the top of the ForLoop
page, not the Python section). It's a
wiki, this can be improved.
Ideally you could "slice" the wiki
however you chose to see e.g. the top
20 tasks for two languages
side-by-side.
http://hyperpolyglot.org/ seems to be an almost perfect match for what I was looking for. The quality is not always there, or idiom can be lacking, but it has the same intention and is pretty comprehensive.
Following on from this question, I am interested in finding out how you could measure the popularity of any and all programming languages.
As professional developers, we need to be aware of the trends in the software industry - what languages will employers be looking for in the coming few years, and we should be proficient in. Also, it can allow us to spot opportunities - perhaps there are opportunities for new developers to branch out into mainframe programming as older members of the profession retire. For this reason, it is important for us to track programming language popularity.
There are number of questions already on Stack Overflow (here and here) about how SO could be used to measure a language's popularity (or the difficulty in using said language). Other methods include tracking job adverts (i.e. http://www.hotskills.net/) and search engine query statistics (i.e. http://langpop.com/).
Can the SO community think of any other methods of measuring this?
Summary
Use Stack Overflow tags to measure language popularity
Search Engine query statistics
Job adverts
Open Source code repositories
As noted by various contributors below, each of the above sources has problems as a reference to calculate language popularity/usage.
As the author of http://www.langpop.com my approach is to find as many metrics as possible (certainly not limited to just search engine results! We have books, job listings, irc, google code, freshmeat and others) and let people see the methodology, making the whole thing as transparent as possible. That's why I added the javascript feature that lets you recalculate the normalized results with different weights for each metric.
As someone else notes, there are many different ways of measuring popularity. Another important one that he doesn't mention might be the "acceleration" of a given language: for instance, Cobol has a big installed base, but I don't think a lot of new Cobol projects are being started. Something like Ruby is probably the opposite - it's not widely used, but a lot of people are picking it up for new projects.
I disagree with the conclusion that the numbers are "meaningless", though. By looking at the different measurements and thinking about them some, I think there are plenty of interesting conclusions to be drawn. Also, don't confuse "rough" numbers with "useless" numbers. I think we can definitely say that Java is more popular than Tcl, for instance.
I'd say a language popularity and success is exponential to the number of people who hate it.
Not voting the question down, because a lot of people ask about this kind of thing. However...
The next words out of anyone's mouth after this is asked should be, "Popular with who?".
Popular is a useless word to apply to programming languages. There is no universally accepted meaning of it, so there's objective way to measure it.
For example, the obvious thing to do would be to go out and count up worldwide deployed LOC in every software project in use. When you do that, you'd discover that hands-down the most popular language is Cobol.
Someone else might think the obvious way to measure would be by Google hits. Doing that, they'd find that Java gets 282 million results, while C# gets 48 million, and Cobol only gets 6.5 million. So clearly Java is more popular than C#, and way more popular than Cobol.
A third person might think the obvious way to check is to look at SO tags. They'd find the single most used tag here is C# (34K uses so far). Cobol only has been used 65 times here. So clearly C# is the most popular, and almost nobody uses Cobol.
So who is right? All three are. It depends on what you really meant when you asked the question.
For those who are surprised at my Cobol assertion, I suggest reading this (somewhat dated 2003) article on the subject. It will be a real eye-opener. It could be argued that we non-Cobol programmers are all working around the margins of a gigantic Cobol world.
You check the tiobe statistic
What does "popular" mean? Here are some potential ways of measuring it:
The number of developers writing with that language professionally at a given point in time.
The number of people frequently experimenting with or using the language at home at any given point in time.
The number of developers who wish they were using language X (or are happy that they are).
Problems with some measurements:
Using SO questions or Google hits could merely indicate which language (among those in the running for most popular) is the hardest to use.
Counting job adverts would be horribly inaccurate, since people tend to switch to things that don't fall into their original job description, and you would miss all the people currently using a language (not applying for a job).
Personally, I'd like to use number 3 as a measurement of popularity, but I have no idea how you would measure it. The internet would seem like a good place, but which site will be able to attract all the developers, and how would you know that enough of them responded to the poll?
Open source contributions perhaps.
number of posts about that programming language on stack overflow
You can use Google Trend to have an idea. Of course it's not very accurate since you can write "C#" or "C Sharp" but it can give you a brief idea.
This blog article neatly summarizes the various ways of determining the popularity of a programming language:
Determining Programming Language Popularity
The article describes one way of measuring popularity that has so far not been mentioned:
Popularity by Book Sales
In terms of ways that have been mentioned, the article offers specific ways of gathering statistics:
Measured by Commits to Open Source projects - use of the Ohloh website.
Popularity by Lines of Code - use of figures compiled by BlackDuck
Most programming code, I imagine is written in English. But I'm curious how people are handling the issue of naming herein. A lot of programming is done within some bussiness domain, usually with well established terms for certain procedures, items.
I'm from Denmark for instance, and something I work a lot with has a term called "indblikskode", which sort of translates to "insight code". So, do I use the line "string indblikskode = ..." in the C# code for some web service related to this? Or do I try to use a translation, such as "insightcode"? The bussiness I'm in isn't even consistent in its language, for instance using the term "organisatorisk enhed" (organizatorical unit), but just as often using the abbreviation "OU", which is obviously abbreviated from the English.
How do other people handle this naming issue, while keeping consistent, and sane (in everything from simple variable names in your code, to database tables, to server names)?
Duplicates:
Should identifiers and comments be always in English or in the native language of the application and developers?
Do you use another language instead of English?
I can only speak for myself, but I always translate terms into English when naming classes and variables, and it's one of our unwritten best coding practices to do so as well. You never know when you might need to hand off development to cheaper labour abroad or the expert expat consultant in town.
The problem with non-English naming of classes and functions is, that you invariably going to end up with macaronic pidgin. Keywords are in English, naming conventions (like for example getters/setters) are also English, same for standard names for design patterns.
You're going to end up with stuff like:
OrganisatoriskEnhedFactory::getInstance()->getIndblikskode();
See my question and answer here.
Basically it depends on your organization and the application. If your company, developers and customers all speak the same native language and you expect it to stay that way, then it would be extremely counter-productive to have everyone become a part-time translator as well. Considerable productivity loss for a purely hypothetical future advantage. YAGNI.
If it's a large international company, or if there are concrete plans to expand internationally or have some work done offshore, it's a different matter, of course.
Having worked in Switzerland (German side ie Zurich) and lived in Germany for a time I can tell you that I've yet to see an environment where the code isn't in English. Sure the application may well be in German (but many professional environemtns are English-speaking anyway) but the code (I've seen) is pretty much all English.
It's hard to write code in other languages. For one thing, the APIs are (nearly) all in English. Java uses JavaBeans naming for example so you have to use set and get anyway and "getGeburtstag" just doesn't have quite the same ring to it as "getDateOfBirth".
Other countries may vary for this has been my experience from the Germanic countries.
We're usually using established English terms (our business domain usually has English terms), but if I can't figure out any suitable term, I could as well use Finnish. Heck, even our comments in code are in mixed languages...
Of course the sensible approach depends largely on whether the source code will ever be used outside the building. In a small shop it's not such a big deal.
I'm working in a company in Austria (so we're talking German) and we are programming in English (variable names, domain objects, GUIs). Makes it a bit more cumbersome, because you have to find the English translations and you have to translate the GUI before releasing the program. I'm not really sure if all the names are really correct.
In contrast in the former company I was working for programmed strictly in German. This was pretty nice (altough German words tend to be longer than English words). After some years the company wanted to use the same program in the USA, so English-speaking programers had to use the same codebase. after this everything got pretty inconsistent- variables, database fields.. in both languages (the English speaking team members didn't talk German).
My experience is that it is easier to handle internationalization in the early beginning (you are forced to do it when you write the program in English) of an application, because it is no big fun localizing a 10000 LOC application. The advantage of writing in another language is that you see instantly what is localized and what is not - altough it's work you have to take in account for that.
To the untranslatable words: we hadn't expierienced that yet - altough it was some work finding the English phrase for "intra-community deliveries" (that's an EU thing). But if that would happen I'm pretty sure we would use the German word.
I live and work in Germany but write English code only. It makes things easier. You can post your code on the net if you want to ask questions or want to publish tutorials about your work.
Also the code looks more "professional" for me.
I also live in and work in Germany for now and we mostly use English except for some old comments in German. I think non-English comments are generally very bad idea since you'll have to spend time trying to understand it (and understand correctly). Although both German and English are not my native languages, code written in anything other than English seems to be bizarre.
You'll never know who would be working on your code the next day. So you should use the universal IT language.
P.S. Since I do not like non-English languages in my development environment, I made a local administrator quite angry when I refused that my PC be installed with German Windows, German Office and German Visual Studio. It took many hours to download the English versions just for me.
Though I think it is good one day to install a language pack or just a different copy of the same software just to learn the terminology. SQL Management Studio in French makes me really excited, just as when I tried to switch Skype to Spanish.

I think I'm going a little crazy.
Right now, I'm working with the following languages (I was just doing a mental inventory):
C++ - our game engine
Assembler - low level debugging and a few co-processor specific routines
Lua - our game engine scripting language
HLSL - for shaders
Python - our build system and utility tools
Objective C/C++ - game engine platform code for Mac and iPhone
C# - A few tools developed in our overseas office
ExtendScript - Photoshop exporting tools
ActionScript - UI scripting
VBScript - some spreadsheet related stuff
PHP - some web related stuff
SQL - some web and tool related stuff
On top of this are the plethora of API's that often have many different ways of doing the same thing: std library, boost, .NET, wxWidgets, Cocoa, Carbon, native script libraries for Python, Lua, etc, OpenGL, Direct3d, GDI, Aqua, augh!
I find myself inadvertently conflating languages and api's, not realizing what I'm doing until I get syntax errors. I feel like I can't possibly keep up with it, and I can't possibly be proficient in all of these areas. Especially outside the realm of C++ and Python, I find myself programming more by looking at manuals that from memory.
Do you have a similar problem? Ideas for compartmentalizing so you're more efficient? Deciding where you want to stay proficient? Organizational tips? Good ways to remember when you switch from Lua to C++ you need to start using semi-colons again? Rants on how complicated we programmers have made things for ourselves?
Any ideas welcome!
A few things I do to keep them seperate...
Use different IDE's / editors / colour schemes for different languages. You start to associate the language with the environment, and when you switch windows your brain gets a big visual cue that it needs to context switch to the new language.
Try to limit context switching to 2 or 3 active languages at a time. Close down any other IDEs or editor windows when you're done with them.
Try to forget the "fire and forget" stuff. A lot of the languages you've listed seem like they wouldn't be things you're actively coding in every day, but rather tools you use to automate daily tasks. As much as possible try to have a "tool day" where you do any work you need to on those tools. Seperate it as much as possible from your day to day coding, so your brain doesn't have to worry about page swapping that stuff in and out all the time.
-- edit cue, not queue.
For any language I plan on learning thoroughly, I will write my own syntax highlighting in Vim. I try and make the colouring strict so that the colouring picks up obvious mistakes as I type them. This helps me remember where to put certain syntax items in case I forget (so // doesn't look like a comment in python, and I always have trouble remembering where to put * or [] in C). If I can't remember a function or method name, I guess it, and if it shows up in colour I know I've spelled it correctly. I also try and choose differing colours so that different languages stand out from each other, it helps my brain remember what language I'm writing in.
I think after a while it comes natural to you. When I was first getting serious about programming I was using a variety of languages - Java and C# especially. I found myself accidentally using certain Java features in C# and the other way around. Luckily for me a lot of their features are identical so it saved me there, but as I moved on this wasn't really a problem.
Try spending a significant amount of time with each language. Sit down and read a good book (or a couple) on each language and get familiar with it. Ask your boss if you can spend most of your time on one section at a time. You will begin to catch more of your mistakes before you make them. For the ones you don't, this is why debuggers were created - a programmer's best friend. I have a terrible memory, and I mean TERRIBLE. You may think it makes programming harder for me but it really doesn't. After using a language for a significant amount of time the functions just seem to come to you.
So try spending more time on each language instead of jumping around and trying to learn them all at once. The information will stick with you better and you will become a lot less flustered and confused when coding time comes around. Try doing things that help keep you focused while programming. If a lot of caffeine helps, go for it! If listening to your favorite music helps, go for it! (for me I can't concentrate whatsoever with the smallest sounds, but everyones different).
Best of luck!
The feature I never get right the first time, when I change from one language to another, is arrays. They always have different syntax, and I end up looking them up every time.
Here is a list of my most used languages and how to implement arrays in them:
//Java:
int[] array1 = new int[5];
int[] array2 = {0, 1, 2, 3, 4};
//C/C++:
int array1[5];
int array2[5] = {0, 1, 2, 3, 4};
//JavaScript:
var array1 = new Array(5);
var array2 = [0, 1, 2, 3, 4];
//PHP:
$array1 = array(5);
$array2 = array(0, 1, 2, 3, 4);
//Python:
array1 = []#According to the comments, we don't care about size!
arary2 = [0, 1, 2, 3, 4]; #Could use range to create a sequence
One of the things you find in web-dev is that almost by definition if you want to be capable of end-to-end work you need to be capable of at least 5 languages (SQL, mid tier, html, css, js), and every slightly different project is going to add something else (jQuery? Flash? XML?).
I think you just sort of have to grok this naturally, but two things really help:
learn concepts, not syntax and lean on IDEs and google when you need to (another reason language specific interview questions make no sense), because these are applicable to anything and it's easier to see the domain specific components sliding in and out than to think you're learning something entirely different
where possible stick to the similar families of language syntax - I know I personally find C# considerably more natural to use than PHP because it's sharing syntax with JS and Actionscript, XML because of it's familiarity for me from HTML
I agree: there are too many languages and APIs out there.
If you were a customer, and languages and APIs were just like T-shirts, you would be happy that you have the biggest choice possible. Hey, if you want a statically typed language which gives you a lot of flexibility and high performance, go with C++! If you want something easier to maintain, go with Java or Python or Ruby or you name it. You have the choice. You should be happy.
But the truth is, you're more like a guy building a house, and languages and APIs are like screws and bolts: they're your tools. If you have 1000 different types of screws and bolts, each with different characteristics and limitations, then your job will be a nightmare. You'd be more focused on your tools than on the house you're building (does this ring a bell?). Of course, I know there is no one-size-fits-all bolt, but you certainly could imagine life with just a few different types of bolts, couldn't you?
I think the problem lies in the fact that guys in the building industry love the houses they're building... and we developers just love the bolts. I'm no exception: I just love to learn a new language or framework. Bolts are so beautiful. ;-)
I personally have almost no hope of forward progress without my half-dozen API and language reference bookmarks sitting right on my desktop.
I feel your pain, bro.
I don't know, though; I think multiple-language proficiency (or at least multiple-language-general-awareness) is just sort of the world we're livin' in, and something we're just gonna have get used to. Somehow. Alas, I don't know what the secret is to keeping sane, though. (Although for me, I can say that beer definitely helps.)
Some folks on my team (I work at Real, too, incidentally) develop in C++ on Windows, for Windows, and that's it -- that's all they've been doing for years, and they're great at it, they love it, and they're totally happy doing that one thing really well.
Me, on the other hand -- I've never been able to settle into any one language, and I don't think I'd want to; generally speaking, I've learned about a language a year for the past ten years, some of them unlike any others (ColdFusion, anyone?), and these days, I do almost all of my work in Flash, Flex and ActionScript. If you'd told me two years ago what I'd be doing today, I'm sure I'd have laughed. Keeping up is exhausting sometimes (I posted similarly a while back -- a few good answers from other folks in there, too), but I can't seem to resist checking out the new stuff, keeping current, etc.
One thing I will say, though, following on from John T's and Scott's comments: books are the only way to go. Books, at least for me, along with reading lots of (good -- not bad) code, are the best way to let a language seep gradually and cohesively into your brain, and that just takes time. Like I said, I'm almost two years now with Flash, and I'm only now beginning to feel like I can speak ActionScript fluently. All told, I've probably got ten AS books on my desk, though, and there are two more downstairs waiting for me once I'm finished with the one I'm reading now.
It never ends. Woohoo!
PS: VBScript, though? Ugh, that's terrible. Sorry, man. ;)
One of the advantages of my job is that I am able to switch from one project to another, with different languages, operating systems, coding rules, QA requirements, ...
The only way I found to stay on top is not to know every bit of every language, but to know what are the reference docs and where I can find them. For instance, I use the man command for perl, TCL/TK and various flavours of Unix and Linux, the online Language Reference Manual for Ada, Apple Developer resources for Objective-C and Cocoa.
Any project scheduling you can do to minimize the context switches could be helpful. Can you put off the web development until the C++ code is stable?
Another thing I try to do is have a good "worked example" of a new language. Try and find small to medium sized samples of the language you're currently using, and keep it handy. I find picking up syntax details from a piece of sample code I'm somewhat familiar with is often quicker than digging the details out of a reference manual.
Humans can't multitask. Period.

If you aren't allowed to let other people do the work because they already have full plates, then get more people hired. If you aren't allowed to get more people hired, then maybe people can at least shift priorities so each person can focus a bit more.
For example: If you're full time on the engine, or at any level of commitment beyond bug fixes, why are you working on game logic? And content tools? And build tools? And web development? If you're not talking about a one year time span, with maybe a separate solid month of concentrating on each, then it sounds like you do all the programming, and everyone else just twiddles their thumbs.
Surely you're the expert for only one of these areas, and not all of them. There's that whole "if you got hit by a bus" thing. If you're that guy, then that is job security for you, but terrible for your company and your sanity.
You could try matching up tools a bit more. Move as many things as you can to Python or .Net, since I assume you can't ditch your core technologies for your games.
