NoSQL Data Stores - Mongo

I stumbled across Mongo the other day. MongoDB is one of the non-relational (NoSQL http://en.wikipedia.org/wiki/Nosql) data stores along the lines of CouchDB.

If you're interested, here are some links to MongoDB :
http://www.mongodb.org/
http://try.mongodb.org/
http://www.mongodb.org/display/DOCS/PHP+Language+Center

The try.mongodb.org link is especially useful. It provides a JavaScript shell and a tutorial which allows you to try MongoDB easily.

MySQL won't start - a couple fixes

Let's say you get this message while Linux is booting :

   Starting MySQL database server mysqld     [fail]

One possible cause may be a network setting in /etc/mysql/my.cnf. Look for the following :


    # Instead of skip-networking the default is now to listen only on
    # localhost which is more compatible and is not less secure.
    bind-address    = 127.0.0.1

Change the bind address to your static IP address if necessary.

Start MySQL with

    $ sudo /etc/init.d/mysql start

Using a custom Firefox profile when running Selenium tests

If you use Selenium for testing web interfaces, you'll probably want to create a custom Firefox profile for use by Selenium. To me, the main reasons for this are to provide more screen real estate (remove toolbars etc.) and to speed up browser loading.

But it's a little tricky to get Selenium to find your saved profile.

Here's a great link for this :

Here are the highlights, for a Linux/Ubuntu user :

Start Firefox from the command line and create and save your custom profile :

Row-level and table-level locking in Oracle and MySQL

I had a recent discussion with someone who believed that Oracle's default locking behavior on inserts was table-level locking.

From a practical perspective, the notion that an OLTP database like Oracle would use table-level locks for inserts would lead to such inconceivably bad performance for enterprise applications that I had to research this a bit. From what I can see, default Oracle behavior is ROW-LEVEL locking for inserts.

Can't ssh out : Fixing "Permission denied (publickey,password,keyboard-interactive)."

Suppose you're on a relatively secure Linux box and receive the following message when trying to ssh out interactively (no keys) :

- Permission denied (publickey,password,keyboard-interactive).

Here's one possible solution :

Check the /etc/ssh/ssh_config (client ssh) file and see if it contains this :

- PasswordAuthentication no

If so, change it to the following :

- PasswordAuthentication yes

Now try your interactive ssh session -- you shouldn't need to restart a service or anything else.
