I just watched a video about unit testing WebOS applications and they used the "Palm Host" application. Where can this app and documentation on how to use it be found?
palm-host was a small web server that allowed testing Palm webOS applications in a desktop browser, usually Safari, instead of in the device emulator. With the improvements made in the emulator since the early SDK releases, Palm has removed support for this because the internal Webkit version used on the device has drifted a bit from the version Apple has in their Safari build, and they've got external debugger support on the device/emulator now.
I don't think Palm-Host is supported anymore. It used to allow you to run Palm apps in Safari and use that debugger.
Are you sure it wasn't Palm Mojo or maybe they just meant they were using a Palm host?

Have a look at:
Palm Developer or Palm Developer Main Page.
I found it pretty helpful.

I had experience of building normal web apps for desktop and mobile before, and want to create my own video web app (similar to Youtube TV) on cross platforms, e.g. Smart TVs, game consoles.
I heard of Cobalt recently and all I know so far is a lightweight browser that we could run web applications using a subset of HTML/CSS/JS on it.
I also read the documentation of Cobalt (https://cobalt.dev/) but I'm still confused about it. It seems that Cobalt could be built only on Linux or Raspberry Pi. Could anyone provide some tutorial or explanation about how the development process looks like?
I am trying to get my hands dirty of firefox OS apps. I tried to follow instructions on https://developer.mozilla.org/en/docs/Gecko_SDK
to get the SDK. I downloaded Gecko 22.0 (Firefox 22.0) zip file for windows.
Could anyone please tell me how to build it on windows system. The details given on the website are not as clear as I expected(I had expected them to be like that on android's site). Or is there a binary available for the SDK?
No SDK needed, it is all HTML5. If people talk about SDKs in that context, its often frameworks or maybe tools that can export to HTML5. But generally, you can use all the languages that work in a browser and use them without any framework or SDK to make an app.
The developer docs on Marketplace have this great intro on app development and testing: https://marketplace.firefox.com/developers/docs/quick_start
Happy Hacking!
The "SDK" you are looking for is probably the Firefox OS Simulator Addon for the Mozilla Firefox browser. Actually, all you need to test your applications for most hosted ones is a browser of some sort, but the Simulator (also called as R2D2B2G) lets you preview most of the phones' functionality, API-s and install packaged apps.
Besides installing and testing your applications you will also get a feel of Gaia - the user interface of Firefox OS, written, too, in HTML5.
Like many of the answers here, there's no real SDK, as Firefox OS apps are basically HTML5 web pages with a manifest.webapp The firefox OS Simulator mentioned by Flaki is great to test your app.
I recommend watching this short video from Robert Nyman, one of Mozilla's FFos evangelists on getting started with it: http://www.youtube.com/watch?v=hqyrldlSx_o
And this is a good tutorial on developing an app: https://hacks.mozilla.org/2013/06/building-a-todo-app-for-firefox-os-part-1/
I would like to create a Windows desktop app using HTML5 features, specifically H.264 video,Web SQL Database,FileReader API. I don't want to use AIR (which currently does not support the video tag, instead uses Flash). Ideally I would like an exe file that just wraps the latest version of webkit in a basic window. It should be stand alone, not rely on the user having Chrome etc. installed. It could load an index.html file in the same directory as the exe. That is it.
I have been unable to find anything like this. I was going to build it myself using QTWebkit but the latest version (4.8.0) does not support the Video tag due to some kind of build issue. I assume the 4.8.1 version will fix this.
Does anyone out there know of something like this that is available now?
For anyone coming across this, Titanium for desktop is no longer supported by Appcelerator, but the project is still supported as an open source initiative. As of today (10/14/2012), it is called TideSDK. According to their Twitter account, they're behind in the 1.3 release due to some sponsored work that will end up in the code base.
Additional options not yet mentioned include AppJS (OSS, requires node.js) and Sencha Desktop Packager (quite pricey).
I think titanium is not totally gone. There is this stuff called tideSdk
I couldn't try it out yet also , so video support and the codec are open for your exploration. Here is how they say:
Create multi-platform desktop apps with HTML5, CSS3 and JavaScript
TideSDK is the new standard for creating beautiful and unique desktop
apps using your web development skills.
I recently thought about doing the same thing, you can still do it with air without using flash, but you could also use Chrome Packaged apps, mozilla prism (although inactive today) or Microsoft HTA (html application).
You can think of using a framework that does the browser embedding for you like Titanium. It's mostly used for creating apps that can be published to iphone, android, and windows devices. It will create a windows MSI install.
Another option is to use the CEF project ( Chromium Embedded Framework for C/C++). I havn't looked at it much, so I can't tell you how difficult/easy it is to work with. Their main site also has wrappers for Java, .NET, and other languages.
I am not sure even of a starting point with this.. however knowing that Silverlight works across win/mac platforms (as far as I know!), is it possible to create a silverlight based screensaver?
If not, are there any tools (no flash skills unfortunately!)
Any starter points would be cool..
Thanks!
By now Silvelight is being deprecated, but if you need to run web pages as a screensaver, my startup is creating a product to do exactly that, it's called Screensaver Ninja and you can find more about it at https://screensaver.ninja. That means that all you have to do is develop the web app and leave the screensaver part to us.
Here's a screenshot of how you configure it:
Silverlight is only usable as a web browser plugin on Mac OS X. It cannot be practically used to build screensavers.
Additionally, there's good reason to believe that Silverlight is being abandoned by Microsoft. I'd avoid it for any new development.
I am interested in developing an app for my new iPad purely for my own use. (well to start with at least)
Is there a way to develop an app without a mac?
Can I install the app only on my own iPad without having to sign up to the right to publish it when I might not even want to do that?
EDIT:
Could i use an old G3 powerbook for development? They can be picked up really cheap on ebay. Would something of that spec be up to running the xcode development environment?
I think the best option is to develop the application using HTML5 / Javascript and CSS, and use a service like appMobi or PhoneGap to compile it for IOS. They both have an online service that can make the build for you without needing you to own a Mac.
You have also the added advantage that you can compile your app not only for IOS, but for Windows Mobile, Android, Blackberry and even the good old web.
You have some Javascript libraries like JQTouch that allows you to easily implement the IPhone look and feel in your web app. Normally you can't access the native API from Javascript, but these solutions (appMobi and PhoneGap) offers a Javascript API that you can use to access Camera, GPS, Gyro, etc...
I think normally serious apps are coded for many platforms, and if you don't have the structure to pay to 4 different skill sets, it makes sense to code in HTML5, and from there you have a more future and device proof solution. Even if you "can" pay different developers to code in diffrent mobile platforms I would prefer to do it in HTML5.
Oh, and also take a look at applicationcraft.com, pretty cool online IDE (wysiwyg) connected to PhoneGap, really easy to develop prototypes. The generated HTML/Javascript is not very usefull to continue editing it outside their IDE (a bit complicated), but, again, for something very simple or a prototype it's something you must check out.
Good Luck

Officially, no. Realistically, unless you like wasting countless hours, no.
Can I install the app only on my own iPad without having to sign up to the right to publish it when I might not even want to do that?
No, you must be a paid developer in order to push to anything but the simulator.
xcode for windows.

Yes, you can develop without apple computer (using hackintosh).
And yes, you can install the developed app on your iPad without having to pay for developer program. There are a tons of guides over the internet about running (thus installing) apps on ios devices without developer program.
check this:
How can I deploy an iPhone application from Xcode to a real iPhone device?
You can develop for iOS without a Mac by using Adobe Flex. The Flex SDK is free and Open Source, and includes a compiler + packager. If you want an IDE, you can get Adobe FlashBuilder (not free, but with a free 90-day trial), which makes your development time much more productive.
You would not develop in C, C++, or Objective C, but in a combination of ActionScript (a dialect of Javascript) and MXML (markup language, mainly for rich GUI layout).
On the minus side: you have less control over what you can do (you can still do a lot) and you cannot use the iOS SDK directly.
On the plus side: it is very easy to develop great looking apps, and with very little changes, you can recompile them for Android, Blackberry Playbook, Windows, and Mac OS X.
You do not technically need a Mac to develop an app, unless you are serious about it. There are couple of solutions available to you for developing mac-less.
First, there are some services that port your HTML5 web apps into an iOS app, so you only need to write your code HTML5.
Second, if you dont want to buy a Mac, you can instead buy Snow Leopard or Lion, and build your own "hackintosh" (a windows computer hacked to run off the mac operating system).
Finally, you cannot make your app available for purchase in the App Store unless you are a paid developer. However, you could publish online as an HTML5 web application, or you could publish your app in a third-party app developer market (however you could only intall that app if you jailbreak your iPad).
Not sure how new this is, but Dragon Fire SDK is 100% Windows based (you do submit your code to them for compilation), but at no time are you required to own a Mac.
