While I have used a number of charts like HighCharts, Charts.js, C3, D3, Has anyone tried or is there some documentation around how to include any of the chart frameworks with React-admin? I looked at a few but looks like we have to do a lot of custom development. Your help will be highly appreciated.
I used https://github.com/recharts/recharts and it works great. It has a really good flexible API.

I'm a beginner in dojo. First of all is everything javascript based? For example to create a form I have to use JavaScript or HTML tags?
Also I cannot understand their documentation and tutorials. It's very confusing.
Is there a proper website (other then dojo itself) that has good tutorials?
You can use Dojo's components's (widgets) in two ways. Programmatic and declaritive. The programmatic way (what you are talking about) is by defining widgets through the use of javascript. With declaritive you can define them using HTML markup. David Walsh has a nice short writeup and if you search for "declaritive programmatic dojo" you'll find some questions and answers on the matter:

Difference between programmatically vs declaratively created widgets in dojo?
Declarative coding or programmatic coding in Dojo Projects?
Declarative or programatic approach in DOJO?
If you're having trouble with the tutorials on the Dojo website, i suspect you're better off, first diving into some basic beginner javascript tutorials before trying to learn a framework like Dojo. I concur with the comment Ferry made on your question, there are no better resources than the actual Dojo website. I recommend following every tutorial, starting with the Hello Dojo tutorial and working your way up so that you don't miss out on the basic concepts which you'll need when you read the harder tutorials. Good luck!
For your first question: dojo is javascript-based platform that provide you with a basic javascript library and a bunch of basic widgets (UI controls like button, dialogue, layouts,...), and some extra things. However, you don't really have to use dojo all the time: you still can use dojo to manipulate a html form button; it's just dojo button comes with extra functionalities and might save you some time.
For the second question, I agree with iH8 that dojo website is the best place to start. There are three different ways dojo websites can help you:
Look at the tutorial: Basic steps on how to set it up and use provided functionalities as-is
Look at thetoolkit api: This provides a very detailed view of dojo javascript object (See what extra things you can do with dojo objects)
Look at the nightlytest: I found this very helpful in term of showing me what can be done outside of the tutorial (i.e. how to use things you found in the api)
Other than these, you can look at existing implementation to learn about the toolkit.
Basically, this is how I am learning Dojo. Without more-specific questions, it's hard to tell what is confusing about the tutorial. I would recommend you give it a try and post a question: everyone here will be willing to help you.
I recommend starting with some video tutorial like this.
When you understand the concept, you can try to copy and paste some code from Dojo documentation tutorials or Reference Guide, because all books are out-of-date.
Also you may find some useful information on IBM-related sites like http://www.ibm.com/developerworks because IBM invested in Dojo and uses it for its products.
If you have enough resources ($) you can take participation in Workshops (sitepen.com/workshops)
Completely new to Arduino and am looking to really dive in. An idea I have requires a small form factor for a gsm/gprs module, something that could work with one of the micro arduinos. I can't find any sort of really small gprs modules.
My question:
Is it possible to use the module from an old cell phone and adapt it to arduino? Or is that an outrageous concept? I also found one that looked interesting on (ebay) would it be possible to adapt to something like that?
I am aware that it'd be a big undertaking!
Thanks for the help.
It is possible! most of the modules serially communicates you only need to get the baud-rate correct.
There are examples and tutorials you can find on the internet this Instructables tutorial is worth seeing.
I need to generate some charts and graphs in a Ruby on Rails 3 app.
I have searched around for a gem to help me out and I have found gchartrb, googlecharts and gruff, but the first two seem to be too old to support Rails 3 (last commit is around 2008) and gruff I read that it is not recommended because it depends on ImageMagick and RMagick. But this was also from the year 2007.
HighCharts also have nice looking charts, but I don't have much JavaScript skills
So what gem or what approach would be best to have some bar/line/pie charts in a rails app?
Google has a great library for drawing charts with HTML5 and JavaScript. It's called Google Chart Tools.
You can pick the chart type you want from their Chart Gallery and use it with JavaScript. Even if you don't have much JavaScript skills, the examples should help you to get the job done.
Even if the question was already answered, I would like to suggest Morris for those that will pass here, even with "not much JavaScript skills" you could create nice charts. I also do not have much Javascript skills, but so far it is being easy. You have basically to create a JSON on the server side and set it to a #variable on your Controller. From your view you access this variable from a Javascript code passing it to the Morris calls.
I started using Highcharts a few weeks ago and can tell you that you don't need that much Javascript knowledge (depending on your needs and the complexity of the data). Apart from that those charts look really nice, in my opinion.
There are good tutorials and examples available which can help you. There's also a railscast regarding this topic.
I've another own option - https://github.com/railsjazz/rails_charts
It's using Apache eCharts, so same powerful as Highcharts and have convinient helpers to generate charts in your RoR app.
Could anybody suggest a good open source (as in I can see the source, license irrelevant) webkit-sharp-based application? I've been wanting to jump into development with webkit-sharp and gtk-sharp, but I haven't found much of any documentation on webkit-sharp. I thought a good application example is as good as any documentation.
For anybody else that has this issue, a good application I just found is the sample app included with the source. For anybody answering, I didn't think about checking the source for samples when I posted this. The name of the sample is called FunnyBrowser.cs.
Here's mine:
https://github.com/dmulder/owa_browse
There don't seem to be many examples around of anyone using this. I've been looking through the docs at http://webkitgtk.org/reference/webkitgtk/stable to figure it out.
I want something like Axiis, but without using Flex or other Adobe products.
Have a look at the JavaScript InfoVis Toolkit. Also, maybe the gRaphaël charting library (built on top of Raphaël) can suit your needs.
Others:
Ajax.org
Google Chart API
flot
Style Chart
Bluff
JS Charts
jqPlot
pChart
ExtJS
Vizualize
TufteGraph
milkchart
DojoX Data Chart
jQChart
PlotKit
See whether one of these suits your needs best.
The closest I can think off the top off my head is Google Visualization API
Of course, AFAIK, this will only work for on-line applications. And is Google any less evil than Adobe is a question for you to decide :)
This is a pretty open question, as you havent specified any preference for any particular technology or language.
I do a lot of WPF/C# stuff so I immediately start looking on that stack. Assuming that this would be a suitable platform, then Visifire might be worth looking at... I originally found them here on codeplex.
There seem to be a ton of third party paid for components that can do similar things. Telerik has some visualization tools that may also be worth having a look at.
Is thre any specific scenario that you are looking at, or any specific language? I think we may be able to suggest better alternatives if that was provided.
You could try protovis (JavaScript), looks quite similar.
You can use jqChart - HTML5 jQuery Chart Plugin
