The project I'm working on uses MongoDB for some stuff so I'm creating some documents to help developers speedup the learning curve and also avoid mistakes and help them write clean & reliable code. This is my first version of it, so I'm pretty sure I will be adding more stuff to it, so stay tuned…

I'm currently using MongoDB to record application logs, and while I'm quite happy with both the performance and with being able to dump arbitrary structured data into log records, I'm troubled by the mutability of log records once stored.
In a traditional database, I would structure the grants for…

I am trying to test out mongoDB and see if it is anything for me. I downloaded the 32bit windows version, but have no idea on how to continue from now on.
I normally use the WAMP services for developing on my local computer. Can i run mongoDB on Wamp?

The network is small, but during high load periods some systems can end up dominating the bandwidth. For example, a client downloading a file can easily saturate the connection…

I have 2 nearly identical dedicated servers with the same provider. They also run a nearly identical software stack: RedHat 5 64-bit, Plesk, PHP, Apache, & MySQL. We use them for hosting custom sites we build.
The problem is, while our 1st server has a load average (in top) of around 0.3, the…
