I am looking for alternative guides or tutorials from the ones offered by Microsoft Academy to learn more about sharing objects in the HoloToolkit-Unity that has nothing to do with the HoloToolkit used by Microsoft at the Academy.
As I have seen until now, there are a lot of links and references to those tutorials, as I guess they were the first out there offering a pretty fair way of working with the Hololens.
Microsoft offers both toolkits in two different repositories: one to learn at the academy where each topic has a different adapted HoloToolkit and another one to use in real life.
Bonus:
I could understand that they are different to focus on different matters and then the academy samples can be a bit more light. But academy really focuses on most of the HoloToolkit features, so, why are both toolkits so different?
Some of the differences noted from both toolkits at the 240 Sharing topic are different namespaces (like GazeManager or the ImportExportAnchorManager), amount of code or missing (or at least not finding the equivalent from for example the CustomMessages or GestureManager classes)
The very big counterpart I find to this is that being so different makes actually the learning process almost double, first you have to learn how to use the Academy toolkit and afterwards the normal one.
I don't think this fits very well with the guidelines of stackoverflow, see here: https://stackoverflow.com/help/how-to-ask but I'll weigh in anyway. Those tutorials were put together prior to the holotoolkit existing as it does today on github. The better question is why don't they fix it? Your best bet is to find a tutorial elsewhere to help you get started that uses the holotoolkit such as mine:
http://www.cameronvetter.com/2016/10/21/hololens-development-tutorial-based-on-talk/
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.

Improve this question
Have you ever tried learning a language while on a project? I have, and from my personal experience I can say that it takes courage, effort, time, thinking, lots of caffeine and no sleep. Sometimes this has to be done without choice, other times you choose to do it; if you are working on a personal project for example.
What I normally do in this kind of situation, and I believe everyone does, is "build" on top of my current knowledge of languages, structures, syntax and logic. What I find difficult to cope with, is the difference of integrity in some cases. Some languages offer a good background for future learning and "language study", they pose as a good source of information or a frame of reference and can give a "firm" grasp of what's to come. Other languages form or introduce a new way of thinking and are harder to get used to.
Sometimes you unintentionally think in a specific language and when introduced to a new way of thinking, a new language, can cause confusion or make you get lost between the "borders" of your new and your current knowledge of languages.
What can be a good solution in this case? What should be used to broaden the knowledge of the new language, a new way of thinking, and maintain or incorporate the current knowledge of other languages inside the "borders" of the new language?
I find I need to do a project to properly learn a language, but those can be personal projects. When I learned Python on the job, I first expected (and found) a significant slowdown in my productivity for a while. I read the standard tutorials, coding standards and I lurked on the Python list for a while, which gave me a much better idea of the best practices of the language.
Doing things like coding dojos and stuff when learning a language can help you get a feel for things. I just recently changed jobs and went back to Java, and I spent some time working on toy programs just to get back in the feel for things (I'm also reading Effective Java, 2nd edition as my previous major experience had been with Java 1.4).
I think, in some respects no matter what the impetus for learning the language, you have to start by imitating good patterns in the new language. Whether that means finding a good book, with excellent code examples, good on-line tutorials, or following the lead of a more experienced developer, you have to absorb what it means to write good code in a particular language first. Once you have developed a level of comfort, you can start branching out and and experimenting with alternatives to the patterns that you've learned, looking for ways to apply things you've learned from other languages, but keeping within the "rules" of the language. Eventually, you'll get to the point where you know you can 'break the rules" that you learned earlier because you have enough experience to know when they do/don't apply.
My personal preference, even when forced to learn a new language, is to start with some throw away code. Even starting from good tutorials, you'll undoubtedly write code that later you will look back on and not understand how stupid you could have been. I prefer, if possible, to write as my first foray into a language code that will be thrown away and not come back to haunt me later. The alternative is to spend a lot of time refactoring as you learn more and more. Eventually, you'll end up doing this, too.
I would like to mention ALT.NET here
Self-organizing, ad-hoc community of developers bound by a desire to improve ourselves, challenge assumptions, and help each other pursue excellence in the practice of software development.
So in the spirit of ALT.NET, it is challenging but useful to reach out of your comfort zone to learn new languages. Some things that really helped me are as follows:
Understand the history behind a language or script. Knowing evolution helps a lot.
Pick the right book. Research StackOverflow and Amazon.com to find the right book to help you ease the growing pains.
OOP is fairly common in most of the mature languages, so you can skip many of the chapters related to OOP in many books. Syntax learning will be a gradual process. I commonly bookmark some quick handy guides for that.
Read as many community forums as possible to understand the common pitfalls of the new language.
Attend some local meetups to interact with the community and share your pains.
Take one pitch at a time by building small not so complicated applications and thereby gaining momentum.
Make sure you create a reference frame for what you need to learn. Things like how security, logging, multithreading are handled.
Be Open minded, you can be critical, but if you hate something then do not learn that language.
Finally, I think it is worthwhile to learn one strong languages like C# or Java, one functional language and one scripting language like ruby or python.
These things helped me tremendously and I think will help all software engineers and architects to really gear for any development environment.
I learned PHP after I was hired to be the project lead on the Zend Framework project.
It helped that I had 20 years of professional programming background, and good knowledge of C, Java, Perl, JavaScript, SQL, etc. I've also gravitated towards dynamic scripting languages for most of my career. I've written applications in awk, frameworks in shell, macro packages in troff, I even wrote a forum using only sed.
Things to help learn a language on the job:
Reading code and documentation.
Listening to mailing lists and blogs of the community.
Talking to experts in the language, fortunately several of whom were my immediate teammates.
Writing practice code, and asked for code reviews and coaching.(Zend_Console_Getopt was my first significant PHP contribution).
Learning the tools that go along with the language. PHPUnit, Xdebug, phpDoc, phing, etc.
Of course I did apply what I knew from other programming languages. Many computer science concepts are language-universal. The differences of a given language are often simply idiomatic, a way of stating something that can be done another way in another language. This is especially true for languages like Perl or PHP, which both borrow a lot of idioms from earlier languages.
It also helped that I took courses in Compiler Design in college. Having a good foundation in how languages are constructed makes it easier to pick up new languages. At some level, they're all just ways of abstracting runtime stacks and object references.
If you're a junior member of the team and don't know the language, this is not necessarily an issue at all. As long as there is some code review and supervision, you can be a productive.
Language syntax is one issue, but architectural differences are a more important concern. Many languages are also development platforms, and if you don't have experience with the platform, you don't know how to create a viable solution architecture. So if you're the project lead or working solo, you'd better have some experience on the platform before you do your design work.
For example, I would say an experienced C# coder with no VB experience would probably survive a VB.NET project just fine. In fact, it would be more difficult for a developer who only had experience in C#/ASP.NET to complete a C# WPF project than a VB ASP.NET project. An experienced PHP developer might hesitate a bit on a ColdFusion project, but they probably won't make any serious blunders because they are familiar with a script based web development architecture.
Many concepts, such as object modelling and database query strategies, translate just fine between languages. But there is always a learning curve for a new platform, and sometimes it can be quite nasty. The worst case is that the project must be thrown out because the architure is too wrong to refactor.
I like to learn a new language while working on a project, because a real project will usually force me to learn aspects of the language that I might otherwise skip. One of the first things I like to to is read code in that language, and jump in. I find resources (such as books and various internet sites) to help as I go along.
Then, after I've been working on it for a while, I like to read (or re-read) books or other resources on the language. By this time I have some knowledge, so this will help solidify some things and also point out areas where I am flat-out wrong in my understanding. For instance, I can see that I was making incorrect assumptions about similarities between languages.
This also applies to tools -- after using a tool for a while and learning the basics, reading (or skimming) the documentation can teach me a lot.
In my opinion, you should try to avoid that. I know, most of the times you can't but in any case try not to mix the new language with the old one, and never add to the mixture old habits, practices and patterns.
Always try to find resources that will help you get through the new language in the way the language works, not in the way other languages do; that will never have a happy ending, and if it does it will be very hard to modify it to the right way.
Cheers.
Yes I have.
I mean, is there another way? The only language I ever learned that was not on a project was ABC basic, which was what you used on my first computer.
I would recommend if you start with a certain language, stick with it. I only say that because many times in the past I tried more and more different ones, and the one I started out with was the best :D
Everytime I have/want to learn a new language, I force myself to find something to code.
But to be sure I did it well, I always want to be able to check my code and what it ouputs.
To do so, I just try to do the same kind of stuff with languages I know and to compare the outputs. For that, I created a little project (hosted on Github) with an exercise sheet and the correction for every language I learnt. It's a good way to learn in my opinion because it gives you a real little project.

I'm supposed to learn how to use LabVIEW for my new job, and I'm wondering if anybody can recommend some good books or reference/tutorial web sites.
I'm a senior developer with lots of Java/C#/C++ experience.
I realize that this question is perhaps more vague than is intended on stack overflow, so how about this? Please answer with one book or web site and a brief description. Then people can vote up their favourites.
It will take some training and some time to learn the style needed to develop maintainable code.
Coming from Java/C#/C++, you probably have a good idea of good software architecture. Now you just need to learn the peculiarities of LabView and the common pitfalls.
For the basics, National Instruments offers training courses. See if your new employer can send you to a Basics I/II class to get your feet wet. They offer some online classes as well. Following classes, you can sign up to take tests for certification.
Get an evaluation copy of Labview from National Instruments; they have a well maintained help file that you can dive right into, with example code included. Look at "Getting Started" and "LabVIEW Environment". You should be able to jump right in and become familiar with the dev environment pretty quickly.
LabVIEW, being graphical is nice, but don't throw out your best practices from an application design point of view. It is common to end up with code looking like rainbow sphaghetti, or code that stretches several screens wide. Use subvi's and keep each vi with a specific purpose and function.
The official NI support forums and knowledgebase are probably the best resources out there at the moment.
Unofficial sites like Tutorials in G have a subset of the information found on the official site and documentation, but still may be useful for cross reference if you get stuck.
Edit: Basics I/II are designed to be accessible to users without prior software development experience. Depending on how you feel after using the evaluation version, you may be able to move directly into Intermediate I/II. NI has the course outlines available on their website as well, so you know what you're going to cover in each.
LabVIEW for Everyone is recently revised and quite comprehensive. Other than the free stuff available on the Web, this is probably the best place to start learning the language.
The LabVIEW Style Guide is a great book on how to organize and arrange your code and files for maximum benefit.
Object oriented programming is a recent addition to LabVIEW. The LVOOP white paper explains much about how it works and why the way it is the way it is.
It's a bit out of date, but LabVIEW Advanced Programming Techniques by Bitter, Mohiuddin and Nawrocki is still full of useful stuff.
The National Instruments forums are a great place to go for basic help. The LabVIEW Advanced Virtual Architects (LAVA) is the community forum for advanced topics.
Tutorials in G, also check out the webring.
-Adam
The official NI support page and support forums are hard to beat.
It really helps having a guru around for LabVIEW.
'Arc the daft' pretty much nailed exactly what one should try to do to learn LabVIEW. However, I would not skip Basic's I and II. The classes do teach basic programming concepts and are geared to non-programmers, however they do cover the IDE extensively. The LabVIEW IDE is strange coming from a text based language and spending the time in the class learning it with an instructor can really accelerate your learning.
I would skip Intermediate 1 if you are a seasoned developer. Intermediate 1 tries to teach software engineering practices in the span of a three day course. If you are studying to get your CLD you need to know the course and the terminology for the exam, otherwise I wouldn't spend my time or capital in the course.
Subscribe to the Info-LabVIEW mailing list. It's got a lot quieter in recent times as the NI and LAVA forums have grown in popularity, but it's still read by some very experienced and helpful people, including people at NI, and if you can't find what you need elsewhere then a good question will usually get a good answer.
The NI style guide, as already mentioned, is a good reference - re-read it as you learn about more of the things it covers, it contains some densely packed good advice.
Personal top tips: look at the supplied example code (although it's not necessarily perfect); learn to use queues and notifiers as soon as possible; don't dive in to using event structures and control references until you've figured out what you can and can't do without them; and start small and simple - you should find it easy to reuse this code later on by repackaging it into subVI's as the scope of your ambitions increases. And have fun!
For me the best way to learn LabVIEW was by analyzing the in-build examples. The best forums are NI Developer Zone Community and LAVA Forums
LabVIEW is really easy to work with but the tricky bit is to know how to design your application so that it will not becaome a spaghetti. Once you get the basics (e.g. LabVIEW Introduction Course) learn how to use design patterns, events, queues, typedefs and references. Use modular architecture, avoid big structures, try 'writing' your code in small window.
It is also important to know the differences between LabVIEW versions (full/pro, and ver 7.1.1, 8.2, 8.5, 8.6, 2009), how to use version control system with the vi's (binary files), and how to keep your files in project so that you can easily reuse any code and be "DRY" (don't repeat yourself), how to build executable and what LabVIEW RunTime Engine it needs (for customers), what is DAQmx and how to use it, what are VISA drivers and which version is correct for you settings, how to use Measurements & Automation program..
When I started with LabVIEW a few years ago I was given a link to the LabVIEW Graphical Programming Course. It covers the basics and having a sound knowledge of other programming languages I think helped me pick things up quickly.
I would start with the LabVIEW wiki.
Specifically, LabVIEW Tutorial. There are lots of online references and links to LabVIEW reference books. Welcome to the world of LabVIEW!
I would suggest you start with LabVIEW for Everyone. Its a good book which covers the basics of LabVIEW well.
Locked. This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions.
It wasn't that long ago that I was a beginning coder, trying to find good books/tutorials on languages I wanted to learn. Even still, there are times I need to pick up a language relatively quickly for a new project I am working on. The point of this post is to document some of the best tutorials and books for these languages. I will start the list with the best I can find, but hope you guys out there can help with better suggestions/new languages. Here is what I found:
Since this is now wiki editable, I am giving control up to the community. If you have a suggestion, please put it in this section. I decided to also add a section for general be a better programmer books and online references as well. Once again, all recommendations are welcome.

What about you guys? Am I totally off on some of there? Did I leave out your favorite language? I will take the best comments and modify the question with the suggestions.
I know this is going to seem old-fashioned, but I don't think much of using online tutorials to learn programming languages or platforms. These generally give you no more than a little taste of the language. To really learn a language, you need the equivalent of a "book", and in many cases, this means a real dead-tree book.
If you want to learn C, read K&R. If you want to learn C++, read Stroustrup. If you want to learn Lisp/Scheme, read SICP. Etc.
If you're not willing to spend more than $30 and a few hours to learn a language, you probably aren't going to learn it.
These are all really good, written by academia and (some) are books (an unpublished oreilly book --translated from French, but no issues I've found), for example). I've *'d my favorite ones that helped me the most.
ocaml :
*Introduction to ocaml
Using Understand and unraveling ocaml: practice to theory and vice versa
*Developing Applications using Ocaml - O'Reilly
The Objective Caml System - Official Manual
A Concise Introduction to Objective Caml
Practical Ocaml
Haskell :
Explore functional programming with Haskell
*Real World Haskell
*Total Functional Programming
For C#:
CLR via C#
C# in Depth
For C++, I suggest Accelerated C++ by Koenig and Moo as a beginning text, though I don't know how it would be for an absolute novice. It focuses on using the STL right away, which makes getting things done much easier.
Haskell:
O'Reilly Book:
Real World Haskell, a great tutorial-oriented book on Haskell, available online and in print.
My favorite general, less academic online tutorials:
The Haskell wikibook which contains all of the excellent Yet Another Haskell Tutorial. (This tutorial helps with specifics of setting up a Haskell distro and running example programs, for example.)
Learn you a Haskell for Great Good, in the spirit of Why's Poignant Guide to Ruby but more to the point.
Write yourself a Scheme in 48 hours. Get your hands dirty learning Haskell with a real project.
Books on Functional Programming with Haskell:
Lambda calculus, combinators, more theoretical, but in a very down to earth manner: Davie's Introduction to Functional Programming Systems Using Haskell
Laziness and program correctness, thinking functionally: Bird's Introduction to Functional Programming Using Haskell
Effective Java is a must but I recommend being comfortable with Java first to fully understand the examples.
Ruby
The Free Ruby on Rails Training Online Course by Sang Shin Isn't too bad. It also has a decent amount of further reading links on each subject in the course
I'd add Bruce Eckel's programming books:
Thinking in Java (print version: 4th edition; 3rd. ed. is online: http://www.mindview.net/Books/TIJ/)
Thinking in C++ (2nd ed, freely available online: http://mindview.net/Books/TICPP/ThinkingInCPP2e.html
In general, his "Books" page (http://mindview.net/Books/) is a good resource. The freely availabe books can also be found at http://www.ibiblio.org/pub/docs/books/eckel/
Can't believe nobody has mentioned the Perl Best Practices. There's also a Twitter feed that delivers one PBP per day.
I learned Perl from Robert's Perl Tutorial, which I recommend, but it hasn't been updated since 1999. A newer recommended tutorial is Steve's Perl Tutorial.
For web development with Perl, the clear winner is Catalyst, and the Catalyst wiki is the starting point for learning.
For Lisp and Scheme (hell, functional programming in general), there are few things that provide a more solid foundation than The Little Schemer and The Seasoned Schemer. Both provide a very simple and intuitive introduction to both Scheme and functional programming that proves far simpler for new students or hobbyists than any of the typical volumes that rub off like a nonfiction rendition of War & Peace.
Once they've moved beyond the Schemer series, SICP and On Lisp are both fantastic choices.
check out the programming section of wikibooks
Many of them are fully formed, and quite a few have more advanced sections (which are in varying states of completion) on specific functionality.
also, w3 schools has a great php tutorial and reference section
their html and css sections are good for reference too.
C++
Thinking in C++ by Bruce Eckel
C++ Coding Standards by Herb Sutter & Andrei Alexandrescu
The first one is good for beginners and the second one requires more advanced level in C++.
C - The C Programming Language - Obviously I had to reference K&R, one of the best programming books out there full stop.
C++ - Accelerated C++ - This clear, well written introduction to C++ goes straight to using the STL and gives nice, clear, practical examples. Lives up to its name.
C# - Pro C# 2008 and the .NET 3.5 Platform - Bit of a mouthful but wonderfully written and huge depth.
F# - Expert F# - Designed to take experienced programmers from zero to expert in F#. Very well written, one of the author's invented F# so you can't go far wrong!
Scheme - The Little Schemer - Really unique approach to teaching a programming language done really well.
Ruby - Programming Ruby - Affectionately known as the 'pick axe' book, this is THE defacto introduction to Ruby. Very well written, clear and detailed.
For Javascript:
Javascript: The Definitive Guide
Pro Javascript Techniques
For PHP:
PHP Objects, Patterns, and Practice
For OO design & programming, patterns:
Object-Oriented Software Construction (a bible, maybe the Head First OO would be nice, I don't know it)
Head First Design Patterns (I so love this book)
Design Patterns
For Refactoring:
Refactoring: Improving the Design of Existing Code
Working Effectively with Legacy Code
For SQL/MySQL:
Joe Celko: Tree and Hierarchies in SQL (only on a specific subject, but I found it interesting)

C Primer Plus, 5th Edition - The C book to get if you're learning C without any prior programming experience. It's a personal favorite of mine as I learned to program from this book. It has all the qualities a beginner friendly book should have:
Doesn't assume any prior exposure to programming
Enjoyable to read (without becoming annoying like For Dummies /
Doesn't oversimplify
Let's not forget Head First Java, which could be considered the essential first step in this language or maybe the step after the online tutorials by Sun. It's great for the purpose of grasping the language concisely, while adding a bit of fun, serving as a stepping stone for the more in-depth books already mentioned.
Sedgewick offers great series on Algorithms which are a must-have if you find Knuth's books to be too in-depth. Knuth aside, Sedgewick brings a solid approach to the field and he offers his books in C, C++ and Java. The C++ books could be used backwardly on C since he doesn't make a very large distinction between the two languages in his presentation.
Whenever I'm working on C, C:A Reference Manual, by Harbison and Steele, goes with me everywhere. It's concise and efficient while being extremely thorough making it priceless(to me anyways).
Languages aside, and if this thread is to become a go-to for references in which I think it's heading that way due to the number of solid contributions, please include Mastering Regular Expressions, for reasons I think most of us are aware of... some would also say that regex can be considered a language in its own right. Further, its usefulness in a wide array of languages makes it invaluable.
Common Lisp
For a good reference of CL check out Common Lisp the Language, 2nd Edition

Stephen G Kochan,
Head First Javascript is a good intro to JS for beginning programmers - it creatively explains basic programming concepts using JS syntax. The Head First series is based on researched techniques for helping you learn and remember new information. They have you do a lot of exercises and puzzles which might seem juvenile, but really help cement the knowledge in your brain.
One exercise I really liked was after they explained data types, they show a picture of a city street and say "label all the data types you can find in this picture." So the blinker on a car is a boolean, the sign on the store is a string, and the address is a number. That helped me get the idea of how to translate real information into a program.
Based only on this book, I'd say the Head First series is a great way to learn something the first time, but the story-like format they have would make them difficult to use as references.

JS: a re-introduction to JavaScript is the introduction to the language (not the browser specifics) for programmers. Don't know a good tutorial on JS in browser.
Great idea by the way!
Given recent developments I think it's important to include the recent explosion of free online course offerings from universities and private companies. The new boston is a tutorial site i've always used for numerous languages for years, great beginner point.

I second Kristopher's recommendation of K&R for C.
I've found the "Essential Actionscript 2.0" book quite useful for AS coding (there's an AS3 version out now I believe).
I've found that having real books to thumb through is more helpful than an online reference in some cases. Not really sure why though.
hmm, I don't know if I would say that online materials are useless, but I do agree that there is something about books. Maybe they are better written, or maybe it is the act of forking over $50 that makes you more inclined to study the material.
Either way, I agree that books should be part of this question. If anyone has any suggestions for books for languages I will edit the post with the best suggestions.
The reference you have listed for Ruby is for Ruby on Rails. While still ruby deep down, it is definitely not a place to start for people wanting to learn Ruby.
For Ruby tutorials, I would suggest Why's (Poignant) Guide to Ruby as a great starting point for anyone interested in the language.
If you would want to get into more detail, I would recommend the book Programming Ruby, which has become the standard for all things Ruby. The third edition is currently being written, highlighting Ruby 1.9 features, so I would hold off for a while if anyone is considering buying this book.
For J2EE you have a very comprehensive tutorial at:
http://java.sun.com/javaee/5/docs/tutorial/doc/
For Java, I highly recommend Core Java. It's a large tome (or two large tomes), but I've found it to be one of the best references on Java I've read.
I know this is a cross post from here... but, I think one of the best Java books is Java Concurrency in Practice by Brian Goetz. A rather advanced book - but, it will wear well on your concurrent code and Java development in general.
The defacto standard for learning Grails is the excellent Getting Started with Grails by Jason Rudolph. You can debate whether it is an online tutorial or a book since it can be purchased but is available as a free download. There are more "real" books being published and I recommend Beginning Groovy and Grails.
C#
C# to the Point by Hanspeter Mössenböck. On a mere 200 pages he explains C# in astonishing depth, focusing on underlying concepts and concise examples rather than hand waving and Visual Studio screenshots.
For additional information on specific language features, check the C# language specification ECMA-334.
Framework Design Guidelines, a book by Krzysztof Cwalina and Brad Abrams from Microsoft, provides further insight into the main design decisions behind the .NET library.
