I want to start on a new project regarding screen recording from web browsers, probably using a plugin or something similar (if it is possible). Basically I need a web interface from where the user runs something like a plugin, select the area where the screencast should be, press the record button, talk for maximum 5 minutes then the video should be uploaded to my server for further review. (I am doing this for a school project where the students/users use this max 5min videos to tell the teacher about an issue/problem etc.). I've researched (Google it :D) about different methods that I can use. I am a student aswell and I have a limited amount of programming knowledge mostly with python, html, css, javascript, objective c & php but I am more then glad to learn something new if is required. I've found an open-source plugin called ScreenBird
https://github.com/adamhub/screenbird
This is what I need but it requires from what I know a Python Server (correct me if I am wrong) which I don't have from the school. I can work only on a Apache server from where my issue, otherwise the ScreenBord should be enough. I don't want to go so much into programming the plugin because I want to work on the design of the website mostly for a better presentation. I really want to start working on this as soon as possible but now I am stuck on what tool to use and that's why I am writing this question: What is the best web-based screen recorder plugin for my needs?
For the Screen Installation instructions are given here: https://github.com/adamhub/screenbird/blob/master/README.md
I don't think you need a python server. You just need python installed.
You should be able to run it on localhost and local network, if you don't need it on the internet. Buying hosting for a python server might be useful in this case, its not too expensive :http://www.whoishostingthis.com/compare/python/#
You didn't mention what type of server you have access to, default could mean anything (Apache, IIS, TomCat etc)

I have written a Python application that takes about 4 numbers from the user and does some calculations with it. The final result is displayed on a matplotlib graph. Now, I would like to take this application and put it on a web site. I want to have users sign up for a yearly subscription, do their calculations and print the results to a PDF to be saved on their computer. Because I know Python (but just a beginner at that), I tried to learn Django, but I hit many road blocks with Python version management, getting bunch of error messages that I could not debug. My question to you is what current tools and programming language would you recommend (Java, PHP, HTML, others). I am willing to learn and try anything. I'd rather be able to look at others' code to understand what they did and how they did. Thank you.
Sounds like you are trying to build a large complex application before learning the basics. Python is fine for a server side language but you will need to get a good understanding of HTML, CSS and Javascript to pull pretty much anything of value off when it comes to the web. Take a look at sides like Team Treehouse, Code School or Code Academy. They all have great courses to give you some more knowledge around not only HTML, CSS and JS but how to leverage those technologies into a system like explained above. Good luck!

I am learning java for first time. I have found it's very similar to haxe and flash as3.
However, i am also learning android. And in that i have learned that android overwrites many native java libs to improve speed or something.
Now this creates a problem...i am learning java separately because tutorials about android assume you know java. And this means continuing this path will result in me learning it one way and then the right way. Wasting brain...
So can someone clear confusion. Are all libs covered at http://developer.android.com/reference/packages.html ...or java in android also support more native libs. How would i know which libs are added/overwritten by android into native libs..
also can you suggest what libs/methods i should know to be not stuck at every step.
By libs i mean packages and methods.
Look here for Android Tutorials and docs, and use the reference you've already found.
http://developer.android.com/training/index.html
You may find it goes smoother if you finish learning Java first. The GUI is completely different from Java, but works well. Some Java Classes from older Android API levels are missing some methods, but that is all documented in the developer reference.
Learn Java, skip the graphical / GUI part and you're fine, I think. You can use almost everything from plain java. There are just minor differences like using threads. But that's nothing to worry about.

We are at the starting point of a GUI focused webapplication. Business logic will be in the background. The web GUI will have multiple languages and will also contain complex charts. Chart data will be calculated via the webservice in the background, accessed via REST interface. All input fields should get validated on entering new values. The application must also run well on tablets. What is the best Java Scripts Frameworks or any combination of framework recommanded for this approach. Is Dojo the choice or better GWT? What is your experiance, other better recommendations?
Too many possible answers. Personally I like GWT. It's very flexible. But also I'm a Java developer and I don't like Javascript, and GWT saves you (mostly) from the pain and torture of writing Javascript.
Anton,
Really a matter of choice and personal taste, however, if you want to adopt a mvvm approach where your client objects are syncronised automatically, I'd suggest knockoutjs. This framework is eveolving daily and takes a remarkable amount of grunt out of complex work. Take a wander over to it:

Quote from the page:
By encapsulating data and behavior into a view model, you get a clean, extensible foundation on which to build sophisticated UIs without getting lost in a tangle of event handlers and manual DOM updates.

I have a Java application. I can expose it using web services or REST (JAX-WS or JAX-RS).
Now I actually want to run it "in a cloud" and expose it as a service. I have read around that there are services e.g. Apigee, Rackspace, Google App Engine... The idea is that I don't want to worry about scale and performance. I want that handled by the host.
What are the options for Java?
Thanks,
David.
After a bit of homework, here's what I am gathering:
This is really about Java PaaS offerings (platform as a service).
In addition to what I previously mentioned,
Google App Engine
Rackspace
Apigee
it's worth adding:
Jelastic
CloudBees
There's also a guide - albeit old - from InfoQ that can be read here.
Depends on amount of money you can spend.
This cloud hosting seems interesting.
There's Heroku too, or even AWS.
Amazon AWS provides auto-scaling features that you can configure so you don't have to "worry about scale" day to day, though you do have to set it up in the first place (you will also have to monitor your bill in case you are scaling big-time ;) ). It works well and provides decent monitoring/visualization if you are happy to do the set up.
I can't say whatthe other systems you are investigating have to offer in terms of automatic scaling though.

Its being a almost 2 months since is started to work with JEE6 and JSF 2.0.
I have to say that in this time i learned lots of things and every day i like the world of JEE6 more and more :)
Now that i understand the very basics the components that i use in my JSF pages, i would like to find some gadget that can help me speed up a little bit my programming(Currently i write all my pages in Eclipse Helios HTML editor).
What i am thinking about is a component palette, plugin for eclipse or desktop software (I dont need a brand new IDE, i already use eclipse Helios) that can help me create a JSF pages within minutes.
Back in college when i started using swing i discovered JFormDesigner it was a really great tool, i was able to create very rich GUI within minutes, it was really easy to use an very intuitive for learning.
I am wondering if is there any tool like that out there, but just for JSF 2.0.
Any suggestions?
You can try and use JBoss Tools.
I used to have all sorts of visual functionality with it - although, some times I tended to do things by hand as it was quicker.
You have the option to install the plugin or simply pay for the IDE: as you probably know, the difference is that buying the IDE you get support from JBoss. Using the open-source version you are getting a version with probable bugs, but workable.
I've been using the open-source version for almost 4 years now and love it.
Good luck!
Inside Netbeans, there is a Palette menu that allow you to create dataTable, edit form ... for entity object in one click. This become very handy for me. Oracle have JDeveloper which, imho, is very awesome. It allow you to create a simple CRUD Java EE web app without even writing a single line of codes. There is a demo on how to use JDeveloper here. Dont forget tool like DreamWeaver can allow you to create rich layout very quickly as well.
