Three new chapters to the Guide
The next three chapters were a bit shorter, so I released them all together. They involve setting up VMs on the customers’ side – the ISP gateway, and the beginning of the customer’s computer.
Guide to Setting Up Your Own Internet in VirtualBox
This is the start of what I hope to be a pretty comprehensive look at the different technologies being used in the internet today. I have started the guide with several chapters, and my goal is to add a chapter every week. Comments and corrections are definitely welcome – please note that in some cases I am learning as I write.
Quick command line backup software
Here’s a simple backup helper software I wrote. It’s a Perl script with a MySQL backend. You run it on files you want to back up, and it stores SHA1 checksums in a database. You can then use it to verify files in your backup drive, or even just on your main hard drive.
I’ve found it quite handy for validating my backups. Hopefully someone out there will find it useful too.
