I'm searching for a library to edit already existing PDF's and add a watermark to each page, for example. Could also be blank every other page etc.
There seem to be a few PDF libraries out there, but only very few of them can edit existing PDF's and I'm a bit lost on which way to go.
Any recommendations?
Thank you.
You may want to think about using a java library through jruby. I'm not hearing a lot of good things about the PDF libraries for ruby.
Something to think about if you are getting desperate.
I have a prawn branch that has this functionality. Unfortunately it's yet to be merged upstream, but I'm hopeful it will happen soon. For more information, try searching the prawn google group for "templates".

I once build a webshop in Rails using the Spree framework. This was great since everything I needed for a webshop came out of the box. Now I want to make a website for people who organize dance parties. The site should have information of the new line-up and location, pictures/videos of older parties, and the possibility to buy new tickets.
I hope if you think of something that can be used which is like what Spree is for a webshop but then for the above requirements I would be very happy if you could share it with me.
Thanks for your help.
Rails is a good framework for this.
Meaning I can't think of anything premade to help you accomplish this, but it doesn't sound difficult to do from scratch.

Hi i'm starting to test data persistance for iOS and i want to use some databases, i tried few project with the command line but i would love to start using a software that will speed up the process.
I read already a post on here where an user listed few software from a website.
Here i copy the link he shared,
http://www.sqlite.org/cvstrac/wiki?p=ManagementTools
i would love to know if any of you tested those software, and which one you raccomand.
On many books i read they use a firefox plugin, but i find firefox already too slow to add such a powerful plugin.
Please if you find this question stupid, don't flag or downvote. I looked for a similar topic and i didn't find the answer i wanted. Thank you
I've always used SQLite Database Browser. It's free, easy to use and gets the job done.

I have used Base: available on the MAC App Store:

I've used Arango Db. It's free http://www.arangodb.org

Is it better to implement blob(connected component) handling manually in openCV or are there any good libraries for the same? I found cvblob and cvBlobsLib? Are these libraries used on a standard scale?
I also looked into this and decided in the end to write my own CCL routine. It seems like a serious omission from OpenCV and no doubt a lot of people are "reinventing the wheel" as a result. Note however that you may be able to use findContours, depending on your exact requirements - see this question.
You should take a look at the new opencvblobslib. It has great features like multi core support.

Thanks,

For an iGoogle type portal you might check ExtJS. Here's a sample
http://www.extjs.com/deploy/dev/examples/portal/portal.html
It sounds like you're more interested in back-end than front-end components. There doesn't seem to be publicly available Rails code for keeping track of a user's widgets at the moment, so you will have to make your own. Good thing you already know Rails!

I know the xxm install guide is a lot to read and doesn't get you up and running as fast and easily as it would when you've seen it done.
So I've installed xxm on a clean Windows install, and made screenshots at every step. I haven't made much tutorials before, and wouldn't even know where to start to make one of those walk-through video's with a voice-over...
Is it clear enough? How could I improve it? (First thing that comes up to mind is I should have set the screen to 800x600)
Should I extend this tutorial with how to include fragments on pages or how to debug a project, or should I make new tutorials about those?
For a programmer or an I.T. person (who is already technically-inclined) that understands the shortcuts and shorthand notations (virt-dir, for example), it's quite good. Although, looking at the website, it should cover running as a standalone HTTP server, as this is claimed to be supported.
