I'm looking for a guide on creating custom emoticons for iOS applications on the iPhone. From what I've read so far it seems to have gotten much easier to do yet I can't locate a tutorial on it.
My research so far on the subject dictates that emoticons you can create may only be useable on a app only platform since the authentic emoticons are based on Unicode built into the phone. Is it possible for someone to add their custom emoticons to the Unicode keyboard on the iphone or would they have to be accepted by he Unicode controlling authorities, if this is even possible at all? It seems feasible that you could activate custom emoticons of your choosing for the Unicode keyboard, or a separate app keyboard accessible in the standard text menu, if your emoticon app presented a unique and highly useful platform for a specific niche, is this a possibility?
Lastly, how difficult is it to create a custom emoticon app? I've seen mixed responses but the more recent they were it always appeared that it became easier to do in more recent the times.
Short answer: you can't create a universal emoticon keyboard like the popular emoji. This is because, like you said, those emoji are mapped to Unicode already in the phone, which is why people without the emoji app installed can still see them. There's nothing stopping your specific app from converting custom Unicode and mapping it to custom emoticons, but these will only be visible in your app -- nowhere else in the phone.
To my understanding, you wouldn't even need your emoticon set to be "approved" if you wanted it to work on all devices -- you would just need manufacturers (like Apple) to build the mapping from the Unicode to your emoticon into the system by default, which seems unlikely.

I have found a corner case where the Unicode system dealing with the Tibetan language is fundamentally flawed. Rather than submitting a ticket, I would really want to learn how Unicode works and see if I can work out a solution myself. I think that would be much better to try to find a solution to the problem and submit that instead of just pointing out a flaw and demanding it to be fixed.
I am reading through the documentation I can find on the official web page and on the ICU web page. The more I read, the more questions come up.
The most pressing question to me is where I can find that logic that handles how multiple characters are rendered into a single glyph.
For instance: the character U+0f62 renders as ར (ra), but when coupled with the character U+0f99 (subjoined nya), it becomes རྙ. This is actually an exception to the rule, because if coupled with any other valid character, for instance U+0f97 ཇ (subjoined ja), the ra character changes the glyph to རྗ.
The font used to render the characters might be a bit small to see, but you can increase the font size of your browser to have a better look. Basically, the first case leaves the ra character almost identical to its common form when the nya character is subjoined to it. In most cases, the ra character whill change into a 'T' shape when another character is subjoined to it.
I would like to know where this logic is implemented, so I can start hacking on it and educate myself on this technology.
Any other recommendations of books and articles are also very appreciated.
Edit: I have been able to do some more tests and reading up on the Unicode specifications. My initial claims are invalid, since Unicode does take account for Tibetan transliteration of Sanskrit. Even highly compounded glyphs. It seems like the logic I am looking for is embedded into the fonts. Thanks to everybody who helped me in my search for knowledge.

This is not a technical question, but I will try to be specific in order to this question to fit into the stackoverflow requirements.
I'm currently facing a task where I have to design hundreds of web forms, integrated in a java web project (JSP pages). I'm searching for a Web Form designer tool with the following requirements:
Drag and Drop interface (to speed up the process);
Open Source;
Database access (not mandatory but at the same time very usefull);
Java integration or Java based (again, not mandatory but at the same time very usefull);
Capable of exporting local files (the forms can not be alocated online, like in many form builders);
I wasn't able to find a tool to fit this requirements. Does anyone knows one?
Thanks
Unfortunately, no there isn't. You can find frameworks that acts as a wrapper and therefore it can save some development time, such as http://www.jformer.com/
There are a few proprietary applications around. Take a look at http://www.wufoo.com/
I've been looking for similar tool without any success. I am thinking about starting an open source project in these lines. But, I do not have anything concrete yet...

With so many tools and technologies lying around, I am looking for suggestions around the best ones (UI/server-side frameworks/database/CMS) to use for building a web(site/app) similar to Facebook itself.
Details of the website cannot be revealed due to privacy concerns. But largely, the experience and interactions would be similar to what Facebook has (such as continuous feeds, groups, upload data/files, comments, etc.), just that it would be in a different domain.
Information (or links) on what technologies/frameworks are such sites/portals using will also be of great help!
Elgg is a great start. they have numerous plugins (some that even make it look very similar to facebook). I've seen some prototypes that where built in a few days that have tons of functionality
The simple answer is PHP. But people likely imagine a LAMP stack.
Facebook has reengineered the front side and back side of PHP, as I understand it. They use the HipHop compiler to cut the cost of execution of PHP. And I don't know the details, but they have some kind of backside distributed database they use instead of PHP/LAMP traditional use of MySQL.
(See http://www.facebook.com/note.php?note_id=24413138919 for a description of one of the mechanisms they use, Cassandra).
If you don't care about scale, you can skip these two steps and save a lot of engineering.

Note: This question IS programming related! It's all about better code and better software concepts through reading what customers say! So please don't close this, as it's important for my (and probably also your) software projects.
In order to write great software, it is essential to read reviews of apps from competitors. That way, you can see what they did wrong and improve on it.
BUT: Apple jails every country into it's own tiny bubble. It's almost impossible to read reviews of users from outside your country. Sometimes, when I'm lucky, Google does return an iTunes website with an app in english and I can read english reviews from people in the US. But most of the times, I end up beeing redirected to iTunes or the App Store app, launching my tiny and insignificant German bubble of some few reviews.
It's ridiculous that these days where the world should be open to everyone, someone like Apple restricts the people to their own countries.
Does anyone have a good advice how to break out from this jail of artificial content witholding? I don't live in China, so I don't want to be threated like if I would. I want to read your US reviews, your French reviews, and even your Pakistani reviews.
I want to make better apps, but I can't if 95% of worldwide reviews are hidden from me as an developer.
Have a look at AppReviewsFinder - small but handy Java application for grabbing customer reviews and ratings from app stores.
At the bottom right of the iTunes web site, there's an round button with the flag of your country. With that button, you can switch the country. I don't know if you can switch to any country.
There's a similar functionality in the iTunes application.
That's the best approach I know. I'd be glad if there was something more useful and less cumbersome.

I'd like to build an app that uses voice recognition. I've seen big companies like Google etc implement this feature, but I'm curious about doing it on a start-up level. Anyone looked into this? Are there any tools out there for us to do this?
OpenEars looks promising...

Based on Pocket Sphinx.
If you start here at wikipedia, you'll get a good list engines (http://en.wikipedia.org/wiki/Speech_recognition#Commercial_software.2Fmiddleware)
As I write this (June 24, 2009) it looks to me that are two viable open source solutions
Pocket Sphinx (http://www.speech.cs.cmu.edu/pocketsphinx)
Julius (http://en.wikipedia.org/wiki/Julius_(software))
Both have been used in iphone apps, but the iphone friendly source isn't readily available.
As I edit this (8 July, 2009) I recently learned that Loquendo (http://www.loquendo.com/en/) has voice recognition and speech synthesis (ASR & TTS) for the iphone.
The best approach will probably be to:
Record the voice on the phone
Send the recording to a server that runs the speech recognition software
Then return something to the phone to indicate what it should do
The Dragon Mobile SDK from Nuance does what is asked for. You need an internet connection to be able to send the audio to Nuance's server and you get a list of text responses. You can then decide what to do with the text responses (e.g. ask your user to choose the one he meant or perform some action). Here is the link:
