• CouchDB: accessing nested structutes in map function

  - by Vegar

  I have a document based on a xml structure that I have stored in a CouchDB database. Some of the keys contains namespaces and are on the form "namespace:key": {"mykey":{nested:key":"nested value"}} In the map function, I want to emit the nested value as a key, but the colon inside the name makes it hard... emit(doc.mykey.nested:key, doc) <-- will not work. Does anyone know how this can be solved?

• Javascript: achieving the Google Ad AJAX effect

  - by johnnietheblack

  I need to create a portable script to give to others to implement on their websites that will dynamically show content from my database (MySQL). I know AJAX has a cross-site problem, but it seems that Google's ad's somehow manage the effect in a cross-browser / cross-site fashion. Knowing that I have to give people a simple cut/paste snippet to put in their website...how can I achieve this? How did Google?

• Installing multiple MySQL .NET Connectors

  - by LookitsPuck

  Hi all, I currently have MySQL .NET Connector version 6.2.3 installed. I'd like to try out Database Manager from within IIS7, however, the dependency is on MySQL .NET Connector 5.2. When running the MySQL .NET Connector 5.2 installer, it says there's already an existing MySQL .NET Connector installed, and that this version can not be installed unless the other is uninstalled. Is there anyway to have both of these instances installed? Thanks! -Steve

• NHibernate second-level cache with external updates.

  - by SztupY

  I've got a web application that is 99% read-only, with a separate service that updates the database at specific intervals (like every 10 minutes). How can this service tell the application to invalidate it's second-level cache? Is it actually important? (I don't actually care if I have too much stale data) If I don't invalidate the cache how much time is needed to the records to get updated (if using SysCache)

• Basic SQL Select in Postgresql fails

  - by Rhubarb

  I am doing a select * on a postgresql table, and everything looks good. But if I do: SELECT Name from People It says: ERROR: column People.Name does not exist SQL state: 42703 Character: 8 But the name column shows up during select *. I've tried: SELECT People.Name from People as well, with the same result. Am I missing something? It should be pretty easy to do this in any other database.

• What is a dictionary attack?

  - by Chris

  When we say dictionary attack, we don't really mean a real dictionary, do we? My guess is we mean a hacker's dictionary i.e. rainbow tables, right? My point is we're not talking about someone keying different passwords into the login box, we're talking about someone who has full access to your database (which has hashed passwords, not plain passwords) and this person is reversing the hashes, right?

• How do I check SQLite3 syntax?

  - by Benjamin Oakes

  Is there a way to check the syntax of a SQLite3 script without running it? Basically, I'm looking for the SQLite3 equivalent of ruby -c script.rb, perl -c script.pl, php --syntax-check script.php, etc. I've thought of using explain, but most of the scripts I'd like to check are kept around for reference purposes (and don't necessarily have an associated database). Using explain would also make it hard to use with something like Syntastic. (That is, I'm only wanting to check syntax, not semantics.)

• NHibernate - auto generate timestamp on create and update ?

  I am trying to map an entity in NHibernate, that should have an Updated column. This should be the DateTime when the entity was last written to the database (either created or updated).

Is there a built-in feature in NHibernate, that can handle this for me ?
