I want to learn how to play with RFID... Read it, write it, scan for it.
I need the software to do this as well as the hardware.
I'm not 100% sure what my end goal is. So, the more sources is get, the better. Keep the comments coming.
The actual hardware to read tags is not so complicated. You can get a reader like this one that can read tags fairly simply. The scanner just sends a unique 10 byte code every time it reads a tag, and you can handle that in just about any software fairly trivially.
I have never written tags because I have never found a need to. You can get tags for under a dollar each, and they all have a unique key. I just record them into my system and store them.
I use rfid for a basic entry control system on my front door, using an arduino controller to send the codes to my central server, and then to open an electronic lock. My setup is sort of similar to what is described here. My server allows me to remotely access it, and to set up specific time based access restrictions for individual tags. The microcontroller is not strictly required, but it allows me an easy way to interface with various hardware elements.
I think you have these options to use for your requirement:
Tikitag RFID Programming Kit http://www.jeremyperson.com/tikitag-rfid-programming-kit/ or this RFID Programming Kit http://www.phidgets.com/products.php?category=14
I hope that helps!

I'm working on Sbire which use google speech-api. There is a some things which I don't like with this api.
First, this is not in streaming mode. It receive small audio files but there is no real pipes.
Secondly, it's not precise. Google does not record our voice to learn our accent. I think it's very important to have a good quality of recognition.
I'm looking for a free api or an open-source tool.
Actually there is a streaming mode, but it requires an API key. Here is an example of how to use it: http://mikepultz.com/2013/07/google-speech-api-full-duplex-php-version/
If you want something that learns, you'll need to create a neural network to handle the data. The best open source tool, however, is CMUSphinx or pocketSphinx(a mini version of CMUSphinx). Here is a link to that tool: http://sourceforge.net/p/cmusphinx/code/HEAD/tree/trunk/
The best part of CMU-Sphinx, however, is that you can set a dictionary of keywords. Instead of outputting gibberish, you can have it ONLY output those commands and finds the command closest to what it thinks you are saying. This make speech recognition incredibly accurate, but only work for a small set of words.

I'm looking for a open source project for dictionary for a language (probably you never heard of it) which has not been "digitized". The dictionary will be from one language to several others, and several others to THE language. Since the language has not been "digitized", I need following features along with searching a word:
1 - Add your own translation to existing words/phrases
2 - Add a new word/phrase and add translation
3 - Request a word/phrase to be translated
4 - Rate (like/dislike or rate within the range) the translation (depending on the rating "correctness" get points")
5 - Possibly relate words (especially nouns) with pictures
6 - Easier to implement mobile version of it
I guess it's more "collaboration site", than dictionary. So the project I'm looking for may not be called as "Dictionary".
I know it's possible to design and write from the scratch, but would be good to begin with something in hand, especially if you are just spending your time/effort for non-profit stuff.
I'm looking around for the project, but didn't find something useful. At the same time designing the architecture in my mind.
If you could share some open source projects, it would be really great.
Thanks.
I am unsure what exactly you need, but would Wiktionary be of any help? There are a lot of localized variations to support different languages and there will probably be a way to ask them to support your language of interest, if it is not already there.

Is there any open source user-guide type creation software available? Or is it best to use wiki type systems? We want to be able to create user guides on the fly through a web front end and accessible on the net. Or is this best achieved using Wikis?
Thanks
I use MediaWiki for a user-guide and help page at my company, and it works really well!
Create custom namespaces for different parts, and if you want to have access controls you can create different groups.
The extensions are great, because you can always find one to do anything you want (ie. print to PDF for an offline copy)
I'd strongly recommend using Wikis. As long as your chosen one's markup covers your needs, it's ideal for user guides.
This post is not 100% on topic - it's about creating user manual for the workplace (as opposed to the software) - but many ideas are still worth reading.
This is a good guide for using Wiki in knowledge sharing.
http://www.futurechanges.org/patterns/
We have used Wikispaces.com to create manuals and guides for several projects. Especially if you are a non-profit with a K-12 educational mission, then current setup for a Wikispace includes Private Projects so you can evolve documentation and make it public when it's appropriate to do so.

My apologies if this is too subjective of a question.
I have a theory about wiki design; specifically, how a particular change to the model embodied by the wiki software would make the wiki revision process more closely resemble the open-source development process and thereby reap benefits that the current wiki model does not.
I would like to develop a proof-of-concept of this modified wiki design by finding an existing wiki package that I can alter. However, it's hard for me to find the optimum balance between the features I need and what my programming skills are actually up to.
I need wiki software that:
is open-source. This is a pretty non-negotiable requirement because otherwise I won't be able to test any modified version under real-world conditions.
implements revisions according to the standard wiki model.
implements security-protected user accounts. The security does not have to be defense-agency-grade, but it does have to take reasonable steps to see that no one can access the abilities available to an account except the owner of that account. (It's great if the software also allows anonymous and/or IP-based editing, but not crucial.)
is as simple and clean in design as possible. It's an extra bonus if it's written in Python or a similarly user-friendly language.
is as fully-featured as possible within the above constraints.
What do you recommend?
MoinMoin seems to meet your requirements (it's in Python, and under GPL; it's pretty feature-rich, including access control as you require).
Do you like Wikipedia? If so go for http://www.mediawiki.org/wiki/MediaWiki It is PHP

I'm in the process of setting up a new website which would greatly benefit from having user-forums.
Since I already have user accounts, and profile details, stored away it seems that I'd benefit from choosing an open-source forum package which I could modify so that logins were tested against my existing database.
Right now all my site is Perl-based, and looking around I don't see many great Perl forums - the only obvious one I could find which is featureful is yabb - but that is written to authenticate against flat files and to be frank the code is nasty.
If I need to use a PHP solution then so be it, but first are there any simple forums that are written in perl that you'd suggest? I'd expect to have different forum-groups and nominate particular users as moderators. More than that I don't need, just basic threading and an attractive appearance.
Really simple forums are often really insecure forums. If you're determined to use perl, a major web forum doesn't come to mind, and if your competent in security I'd say roll your own. You could even release it to the open source community to help people like you. I know there are several great PHP ones out there that aren't so insecure an rather well developed.
I seem to remember that Drupal had a reasonable fit as a module.
