I would like to write a web application using node.js and Cappuccino. I want to write the back-end in Objective-J, just like the front-end.
Can I use node.js with Objective-J? What is needed to do this?
beeing a professional Objective-J coder I can say it is definitely possible since Objective-J is fully based on JavaScript. But I also have to say that I never tried it.
I think it would be a good idea to directly start a discussion in the official Objective-J Google Group:

I am just beginning to learn how to use node JS to make a website. In this website I would like to implement an authentication system. Any tips would be appreciated.
Thanks,

Generally, the way to go especially to start.

I am new to node. I very much like approach of AngularJS. I like what I see in towerjs.
Has Anyone wired the two together? I have in mind tower primarily for backend api/rest and angular for clientside.
I'm especially not familiar with tower.js, but from the docs it looks like it might not be practical to use the two together. There is quite a bit of overlap in the things AngularJS provides and the things tower.js provides (especially models, views, and controllers on the client).
I've written on how to use AngularJS with a RESTful API provided by Express on my blog. Maybe that can help you get started.
Good luck! :)
Tower is for the server-side while angular is on the client right?
So what you could try what is mentioned here. Just replace railway with tower.
You could check this brunch.io skelleton that uses angularjs.
Hope this comes in handy mate!
As things are evolving very fast, there are some major update.
For example, a framework named Total.js has made much work to make Angular.js work in hand with Node.js.
Please have a look at their web site http://www.totaljs.com/totalstack/ and at the 6 (!) example they provide on how to use it : https://github.com/totaljs/examples.
Pretty amazing! Hope that helps!
Note: I have no affiliation with Total.js at all.
I'm new into Node.js and my intention is to build a web site similar (but way less complex) than Imgur, where uploading images is possible by dragging photos from desktop to the browser.
For this I want to use Node.js and MongoDB.
I have been looking around everywhere and found a lots of tutorials (many of them out dated) for setting up a database, but none for file uploading. Node.js and all it's modules is like a jungle, and it really isn't easy to know which modules to use in which type of context.
So, what I really could use here is some help with suggestions of tutorials and/or modules that may fit for this purpose. What is the easiest and best way to get started with this?
This is a school project that I need to do (I selected Node.js for server side myself, not knowing how complex it really is and now it's to late to change), so I would really appreciate your help here.
Thanks in advance!
You can get away without using most of the node.js modules aside from the mongodb driver. Express is a popular framework for web applications, but it might even be overkill here. Really, you just need to serve some HTML with the drag and drop code, and then be able to receive and serve images. It's probably less than 50 lines of code in actual node.js, plus whatever frontend code you have.
Check out this tutorial for the image upload portion on the node.js side using express:
https://github.com/visionmedia/express/blob/master/examples/multipart/app.js
Here's a tutorial for the frontend drag and drop functionality:
http://www.thebuzzmedia.com/html5-drag-and-drop-and-file-api-tutorial/
Update You might also consider http://mongoosejs.com/, which makes mongodb interaction a bit easier--but the native driver isn't too bad to use by itself.
Do you know any node.js application that do something similar to http://olark.com. Not necessarily for multiple website, I just need it for single domain.
I just want to install it myself on heroku and run chat customer support for my website on it.
Thanks,
Michal
Try out opensource-olark. I built it for my own use - it may be useful to you. It is not entirely based on Nodejs. But it works exactly like Olark. It uses strophe.js - A xmpp push based library for jabber which works with BOSH
try http://www.vivocha.com, based on node.js
It's very symple to use and you can integrate with other applications via API (with CRMs and ticketing systems for exemple).
This platform, with only one line of code on your website, allow you to configure all the widgets, without other tech skills needed.
And also, you can adding voice on your website, so you can call with your visitors directly on your web pages.
There are open source tools that you can check out like :
http://nowjs.com
http://www.socketstream.org
They allow you to incorporate realtime features into your nodejs app & you can probably have a very simplified olark-type app in just a couple lines of code.
I know that there are even some web-resources exist which allow you to get a preview of a web-site 'as it looks in a certain browser'.
I only need view from any browser as an image. Is it possible to get that image without people involvement? Can I get it without system programming, just by means of pure java/python/asp.net?
UPD: http://browsershots.org/ is an example of described web-resources.
The tools I know of that does this - really "just" launches a browser (programatically of course) and takes a screenshot of the contents of the browser and saves this in an image.
I think no matter what you do, you will have to find a way of doing something like this. If you by system programming are refering to OS API calls, then I think you will be out of luck. You might be able to get a third party library that can do this for you, but then that library will simply be making those system calls instead.
I see now others have posted links to places that might prove themself useful to you as well. Without having looked at the links, that would probably be the easiest and best way to go.
Good luck
I believe what you're looking for is browsershots
There are some websites that let you do this.
Try BrowserShots
PageGlimpse is a service
providing developers with programatic
access to thumbnails of any web page.
It has API based on REST protocol and some documentation.
You have a lot of things doing this for you. Take a look at stw for instance.
If you're using .NET, it is possible to do this using the DrawToBitmap method of the WebBrowser control (example here). However, as you'll see by the last comment on that example page, it doesn't work with Flash, and it's a bit 'temperamental' with sites that use complex Javascript for rendering.
I think your best bet is to do as others have said and use a third party thumbnail provider. I haven't used it, but http://www.thumbshots.com/ looks good.
