A blog about tech, programming, security, and various other subjects.



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.
No posts lately  Tags: my blog.
I haven't posted anything in a while, I know. I feel like I don't have much to write about anymore, and it's also more pressuring to write now that I have a real audience. Most blogposts were written during the time that I was still developing the website, and I just wrote for myself. I could always decide later whether I publicized it or not. Reading back, the quality mostly sucks, so that's why I'm trying to write original and quality content now. But it's not working.
