I am developing a Blog kinda app where a user can upload images, videos, text, etc.
My problem is that I wanted to stop the users from uploading any explicit content. I need to check whether the image or text contained with any explicit or bad content. Till now I am not able to check if the text contains any explicit contents. In this, I compare the textual words with my database word dictionary. But I feel it is not a perfect solution as the number of words are too many. I wanted to know if this kind of checking is feasible and if it is not possible to do so, then any suggestions that I should follow and most importantly in the case of images. I am ready to use any API if it exist for such problems.
If there are any specific libraries in other platforms can also be helpful for reference purpose.
If you would like to remove spam it is a nice to consider Akismet. (Wordpress installations come with default integration.) There is an another widely used one called SpamWipe.
If you would like to check Plagiarism, there are other tools like the one that small seo tools is providing. You can take a look at copyleaks.com too.
There is a good list for API-s to use in your case:

Of course you could use this kind of API-s in your application.

I am working on a project where I need to create a Video/audio player in java that will allow a user to select a file they want to play and it to play that file. In the future, I am going to get the program to print the conversation of the audio/video file in real time, So i need to some how to create a video/audio player which has a elapsed time which I can be extract for the other component of the software.
I wondered if anyone could suggest some libraries for me to use or give me any advice they think could help me!
Thanks in advance!
I'm not sure what you mean by "print the conversation" but if the issue is knowing how far into the playback stream you are (i.e., elapsed time) then any media player I've diddled with has the ability to establish a listener that gets periodic update events. If your target environment is Android then you can simply use the android.media.MediaPlayer. I've had good results with it. I can't, however, give you a recommendation for a non-Android Java environment.
Also you need to be aware that there some video formats (e.g. Quicktime) may not be supportable with a given player.
You may take a look on Xuggler. Also some alternatives to JMF were covered in Wikipedia.

I have pretty standard java project with standard gradle layout, all sources are stored in git. I want to write documentation in markdown (or similar markup language) and keep all files in project directory (e.g. docs/ folder in the root). Then I want to generate static site or push my sources somewhere to have access to full documentation in html (should be self-hosted solution).
It will be good if I'm able to add simple link to other articles (like I do it in any wiki engine by using [[article]]). And It would be perfect if I've been able to add quick links to javadoc by the same technique as link to articles. And also it would be perfect if it has had built-in search engine.
I've gone through couple of static site generators but I didn't find anything which can satisfy my requirements at least half. Is there something like that? Or I need to code it by myself (I know it won't take to much time)? Maybe there's more common use case for documentation?
You have to use the concept of Doclets. There are some out there. Maybe just try this one:

I'm already using gravatar icons for the users of my web service. However, I'm finding several problems with this approach:
Only a small percentage of the users take the time to set up a gravatar profile. My users are not tech-savvy, but would be likely to add a dedicated photo to my site.
Users of my service are encouraged to use images that depict them in proper uniform for the industry my service relates to. They wouldn't want that same picture to be used for personal purposes throughout the internet.
They would not take the time or effort to manage a separate email address and gravatar account just to have an "in-uniform" profile photo for my service.
Before I implement my own profile image feature, I was wondering if there are any open-source solutions that I could leverage with similar features to gravatar. Specifically:
The ability to display any size thumbnail (up to 512px would be fine)
Takes care of caching different sized thumbnails
Has support for something like identicons, preferably pluggable with different style algorithms (monsters, etc.), even better if I can customize these
Ability to fall-back to gravatar if no photo found
Does anything like this exist? I haven't found it yet if it does.
This is probably a year too late, but you might want to have a look at http://www.libravatar.org
Take a look at MonsterID from the creator of DokuWiki.

I need an open source GIS that allows one to view/zoom/click the maps using a web browser and should be java compliant (deployable on a java app server).
Well, I have tried to structure the requirement in 'what-i-have' and 'what-i-need' lists:
Inputs:
Location: lat/long
Data : Text to display
zoom level: (assume there are about 5)
Output
Data displayed on a Map
Would appreciate all the help I can get.
Thanks.
UPDATE: GeoServer + OpenLayers seems to be the best fit for this requirement
GeoServer: http://geoserver.org/display/GEOS/Welcome
...is what I use. You have work ahead of you no matter what you pick, though. Setting up data sources and making them look nice is a decent amount of effort.
For the client side, OpenLayers is an excellent Javascript library.
I agree with the geoserver response and all the rest of the responses ignore your statement that is has to work with Java. The only other bad option would be to write something yourself using geotools.
Go to the OpenGeo site and see the stack they support. That is the stack you are probably most interested in deploying.
I guess you'll need:
GDAL/OGR to translate the data into a kml file example
Take that KML file and pump it into either:
a. Google maps api or openlayers
b. I've had lots of luck using featuresever which I personally recommend

I am trying to integrate S3 with one of my content management systems. The idea is that I want to have document control features.
The system is quite unique in that it handles thousands of sites, then each site can have any number of contributors or authors who have permission to upload documents and files to the document control module of the site.
I haven't coded the document control module yet, but I would like to get started right away.
I know there are good developer tools for S3 already, however I would really like to make this even easier and even use third party open source products if they are licensable under resale.
Does anyone know of any kind of Java apps for example which makes uploading to S3 easy, or should I just concentrate on developing something which is targetted for my specific case usages.
I do a lot of interface design, but for this, I am really not sure how I should handle it, so I would be grateful also if people could provide examples of websites which have good support for document control and makes it look easy. I don't want something complicated which crazily complex workflow rules, I just want to create something so that site owners can publish documents, images etc. Manage the versions of them and also have a centralised bucket for adding site themes are images.
Here's a good PHP class to get you started with uploading files and managing buckets - http://undesigned.org.za/2007/10/22/amazon-s3-php-class
For java jets3t is the best I hav found: https://jets3t.dev.java.net/
I've used their packaged software and the libs in my own apps and both work very well.
