Ticketmaster / Ticketweb hacked?
This afternoon I received an email with the spammy subject Action Required : Update Your PDF Application. I almost ignored it until I noticed that the link inside pointed to a domain owned by Ticketmaster.

Fixing vim from macports
After installing vim from MacPorts I noticed that neither the arrow keys or backspace work as expected. The solution is simple, create a ~/.vimrc file with the following contents: set nocompatible set bs=2 Reload vim and voila, insert mode behaves as I’d expect it to.

Stupid password rules
Today I forgot the password for a site I use only occasionally. This is rare, as I have a number of password schemes that I use to create a password unique to each site.

dban on a USB stick
After a number of unsuccessful attempts to get dban on a USB stick using unetbootin, I found the Universal USB Installer instead. This appears to do a better job, making a bootable installation from the latest preview build of dban.

Adding fake ethernet headers to pcap files

Occasionally I see packet captures which have been saved as Raw IP, which can really mess up many of the tools developed to deal with pcap. Anything based on libnids, including the Perl module I maintain, cannot deal with it and will produce no (or bizarre) results. Wireshark displays these captures just fine, with “Raw packet data - no link information available” just above the IP layer.

Using the Razor view engine with S#arp architecture
Whilst the Sharp Architecture maintainers have little interest in Razor (see here), I have been using it recently and like the syntax. Swapping out a default project to use Razor instead of (or in addition to) the default engine isn’t too difficult.

Welcome to the IPv6 world

This blog can now be reached over IPv6 (or ipv6.edeca.net), which is surely the final nail in the coffin of IPv4 across the internet.

Net::LibNIDS 0.1 released

The other day I pushed a new version of Net::LibNIDS to CPAN. It interfaces with the C library libnids in order to provide TCP stream reassembly and returns the data to your Perl callback.

Better than grep
Anybody who has used command-line systems for a serious amount of time will love grep. But today I stumbled across ack, which (for many things) is better than grep and a whole lot nicer to use.
