If your administration is as good as anybodies, you are bound to loose the not-so-frequently used password for the SYS and SYSTEM users of oracle. Here are a few ways I found to re-set those passwords: Method 1: SQLPLUS (Tested on AIX Oracle 9.2.0.1.0) Log into the database server as a user belonging to 'dba' [unix ] …

As a Mac user, I have absolutely no problem editting, moving and viewing large video, audio and image files. There was one thing I missed though, and that is a tool which is able to quickly view a large JPG (like OSX's own preview) but then skip to the next image in the directory when selecting "next".

Follow these steps to create an Ubuntu Linux "server" running a Postgres database which allows non-local connections. You will need a machine with at least 10GB HD, bootable from CD-ROM, network card, and preferably more than 200MB RAM. Other than that, it can even be a Mac G4 if you like (just download the …

It scans your iTunes music library, and analyzes the BPM (and intensity of the pattern) of each track. It does this in the background, and on my Mac mini Core duo I can continue wih …

Okay, I found the answer to my problem. Mounting an USB drive on OSX which is formatted as Fat32, will not behave nicely when being accessed through samba. Trying to start multiple copy processes simultaniously will cause seemingly random "file locked" errors. I just formatted the drive as HFS+, and the …

For those of you trying to request a password from the user at the command-line, without the password being displayed on-screen, Java 6 finaly has the answer, along with better access to the console. I hope that soon we will never see this hideous construction to do the same again.

So here I am using iTunes on my Apple. So far so good. The downside is that I have an iBead as an mp3 player, so there are a few problems with that. First of all, iTunes only plays nice with the iPods (and a few other oddballs ;-). For me to put mp3's on my iBead, I can drag them over from iTunes onto the USB drive, …
