IPv6 adoption Tags: networking, my blog, my server.
IPv6 adoption is still rather slow. Some Dutch ISPs promised support during "early 2013". I'd say "early" has come and gone by now. They probably were planning for it, then saw the hype drop off after IPv6 day and rescheduled. Some announced to have delayed it, others never said it would happen. The only ISP that I know supporting a full and free IPv6 connection is XS4ALL. Heck, we get a /64 IPv6 subnet by default at no cost! That's more than twice the entire IPv4 space.

Copyright Tags: real life, writing, other.
Copyright is a funny thing. You have it, without asking for it or telling anyone about it. You can even have it on pseudonyms. And if someone copies your work, well good luck making the distribution undone. Last year the Dutch copyright law became 100 years old, but we're still living by its rules.
What I wonder is why people still put ©<?=current_year;> below their work. It's not legally binding for anyone in any way, it doesn't help protect your content, and it's often very inaccurate.

MAC-address analysis Tags: networking, computers, hardware.
First, a few things you need to know about MAC addresses: When a NIC (Network Interface Card) is manufactured, it is given (issued) a globally unique MAC address. Don't rely on their uniqueness though because users easily can modify them. A MAC address is 48 bits in size (12 characters hexadecimal, as you probably know them), and they are divided up into two halves: the first and the second half! Hard stuff, I know.
The first half is the "OUI" (like the French word for "yes" while forgetting to release caps-lock).

Android's problem Tags: software, apps.
So I've got an Android phone now. A "smartphone" I should probably say: to call this Galaxy Note 2 a "phone" is practically an insult, considering it's got an accelerometer, gyroscope, GPS and even an on-board weather station. Okay, it's only a barometer, but you can replace the S-Pen with a thermometer and probably measure wind speeds with the microphone.
Top of the market quad-core smartphone, great. I don't need 4 cores, but they'll probably turn out useful next time I'm going to do...

What is XSS and how to protect your website Tags: webdevelopment, security, programming.
Alternative title: How do XSS attacks work and how can you exploit it.
To secure things you must know how they work, right? ;) The post mainly focuses on how it works and how to protect your website though, so let's dive right into it.
First of all, XSS means cross-site scripting. The name is a bit misleading since it isn't necessarily cross-site, it's basically just inserting scripts at places where other users will unknowingly trigger them to run.
