How to determine which IP addresses are hitting your web site the most

This is a brief one. Thanks to The How-To Geek for bringing this command into my troubleshooting repertoire.

A bit of background first. This command is helpful to determine who is causing the most hits to your web site. On my music blog, I post a fair number of (totally legal) MP3s. Some less than ethical people often use those MP3s to stream via their site, causing mine to be slower (and a larger bandwidth bill). By figuring out the IP address of the site/person “stealing” my bandwidth I can then block their IP from accessing any of my content. …

Simple Help tutorial helps catch office thief

I got an email the other day from someone who used my How to use your PC and Webcam as a motion detecting and recording security camera tutorial to catch an office thief, complete with pictures. A few folks have left comments mentioning how they’ve used it to catch people doing things they shouldn’t be, but this is the first time someone has sent me pictures.

I thought someone was taking money out of a little change box I have on my desk, quite a lot of money, like $60 this month. So I finally set up a camera, with your help, at 5 pm last night (in the edited by Ross building in downtown Vancouver) and caught this at 7pm. So he’s been fired, by 9am this morning. Turns out he was taking change even from inside peoples drawers… Look at him going into the carpeted office with just a mop?!

So awesome.

How to completely wipe all of the data from your hard drive

This tutorial will guide you in using Darik’s Boot and Nuke (“DBAN”) – to securely wipe (delete) all of the data from your hard drive. Why would you want to securely wipe all of the data on your drive? Perhaps you’re selling your computer, donating it to charity, or recycling it. Before you do so, consider this – even when you delete files, they’re not actually removed from your hard drive. Using data recovery tools, many files can be restored from the average hard drive. In fact, even after a hard drive has been formatted, data can be recovered from it. Using DBAN “prevents or thoroughly hinders all known techniques of hard disk forensic analysis”. …

How to surf the web anonymously using OS X

Using Tor can help you anonymize web browsing and publishing, instant messaging, IRC, SSH, and other applications that use the TCP protocol.

This tutorial will guide you in installing, setting up and using Vidalia – a cross-platform interface for Tor, in OS X. Using Vidalia, you can start and stop Tor, view the status of Tor at a glance, and monitor Tor’s bandwidth usage. Vidalia includes Tor itself, and privoxy – which is a web proxy with advanced filtering capabilities. This might all sound a bit confusing, but it’s actually quite straight forward. …
