• Saving the modified contents of a pdf

  - by Anthony Webb

  I've got a form that I downloaded, I'd like to prefill some content on the form (this is easy using cfpdfform). Where it gets tricky is I would like to allow the user to modify the contents of that form, and then somehow have those modified contents accessible to me.

• What alternatives do I have if I want a distributed multi-master database?

  - by Jonas

  I will build a system where I want to reduce single-point-of-failures, and I need a database. Is there any (free) relational database systems that can handle multi-master setups good (i.e where it is easy to add and remove nodes) or is it better to go with a NoSQL-database? As what I have understood, a key-value store will handle this better. What database system do you recommend for a multi-master (cluster) setup?

  I used the Redgate packager (ran MSI) to reset all the data in my database (i.e. I deleted everything, and let it build the new database).
