Removing AWS EC2 IPv4 Addresses

In July 2023, AWS announced they will charge for IPv4 addresses starting 1 February 2024. The new charge will be the same as the existing charge for an idle IP: $0.005 per hour; slightly over $40 per year per IP address. If you’re running some small T2 or T3 instances for general-purpose workloads, this could increase your monthly cost somewhere between 20–40%. The EC2 free tier will include 750 hours of usage for 12 months, so a single IPv4 address should be pretty much free for that time, but if you’ve exhausted the free tier or have multiple IP addresses, this charge will start to appear very soon.

Google Home So Far

I’ve been playing with Google Home quite a bit recently, with mixed success to say the least.

New Site (Again)

This isn’t the first time I’ve moved my personal site; the first post I still have was after I lost some old blog posts, and I moved to WordPress in 2012 to avoid supporting a separate blog and page builder. However, it was still running on my VPS, and I’ve been trying to remove all production content from there for a while.

An Analogy of DNS Resolution

Imagine that you own a store in the high street. Now, for people to find your store, they can’t just look it up, or walk down the street or anything. They have to rely on some guy (an “informer”) who stands outside their house and says, “The Widget Shop? Yes, it’s on the high street.” People will be able to get to your store, and they’ll remember what the informer told them, but only for a week or so. After that they’ll be like, “Where’s The Widget Shop again?” and have to ask the informer.

Facebook Events in Google (Apps) Calendar

I subscribe to a number of third-party calendars in my own Google Calendar, one of which being my Facebook events. However, there are a couple of issues to work around to get everything working perfectly.

How I Use Smart Playlists to Manage My iTunes Library

I have a fair amount of music in my library, and because I’m a massive nerd I like to keep it in some sort of order. (My pre-iTunes library has some 20,000 tracks, half of which are utter garbage. I’m slowly moving over the good stuff.)

Using Ant and Phing in the same repository

Here’s the scenario: you use Apache Ant for some of your build process, but you also have some tools in Phing. You run both ant and phing from your repository root. Because you use Ant most, the Ant targets are in build.xml, and Phing has to use phing.xml. Sure, you can run phing -f phing.xml ..., but where’s the fun in that? Enter the following build file:

Things I Learnt Today

That Ben “Yahtzee” Croshaw is a goon;
that his early stuff is, if anything, funnier than his paid stuff for The Escapist;
that I there will always be something on the Internet that I haven’t seen, and that someone will think I have been living under a rock to have missed it.

Firefox 3 World Record

The Firefox team are going for a new world record — “Most Software Downloaded in 24 Hours”. The (currently beta) version 3 of their popular web browser is due to be launched in late June. Visit the Download Day 2008 page for the official date, and to make your pledge!

Dell & Linux

I was never a big fan of Dell, mainly because it really annoyed me that they only shipped Windows with their machines. Reading The Microsoft File made it clearer, if no more acceptable; Microsoft bullied retailers to shipping tied processor–product bundles, effectively forcing other operating systems out of the market.

Ooh, Vector Art

Today I stumbled upon this vectorising tool, called textorizer, that converts images into SVG format. You can specify your own text and size, as well as playing around with the edge-finding sensitivity.

My Favourite Number

I love the Internet. I love how countless code monkey hours are wasted trying to stop the inevitable. I love how people actually think it’s possible to remove information from the Word Wide Web.

PHP Snippets

Whilst browsing the old Invisible Shadow network, I was looking to see if any of the old stuff existed on there. One thing I remember was a section for code snippets, both Visual Basic and PHP. It seems that Logan has started it up again. I always recommend that the best way to learn to program is to read others’ code — this kind of website helps with that.

OpenID Now Working

After my attempts earlier this week, I have managed to get OpenID working on the blog. I haven’t yet sorted out any linking of an OpenID with either a Media Network profile or a tag profile, but it’ll be added in soon.

IE7

After downloading Internet Explorer 7 today, I spent the morning sorting out a few CSS bugs across the Media Network. One thing I like is that the :hover pseudo-class is supported across all tags now, rather than just anchors; also position: fixed seems to have been sorted.

Faith Restored in WLM

I have re-installed Windows Live Messenger today, after attempting to get it working before and being a bit miffed. For one thing, the contact list seemed to have lost any control over showing display pictures as per MSN Messenger 7.5, and plugin control for Messenger Plus! Live was handled rather differently.
