Demodulation of the LTE uplink
I have been playing with some LTE recordings to brush up my knowledge, since it isn’t a protocol I’m very familiar with. I’m specially interested in understanding the structure and properties of all the pilot signals. Textbooks and documentation are great, but nothing beats getting your hands dirty with some IQ…

Plausibly deniable encryption (2020)
It is safe to assume that in any useful cryptosystem C k there exists at least one person with access to the key k . An adversary with sufficient leverage can bypass the computational cost of a conventional attack by exerting their influence on this person.

What Every Programmer Absolutely, Positively Needs To Know About Encodings (2011)
If you are dealing with text in a computer, you need to know about encodings. Period. Yes, even if you are just sending emails. Even if you are just receiving emails. You don't need to understand every last detail, but you must at least know what this whole "encoding" thing is about. And the good news first: while the…

We built a secret apartment in the mall (2007)
Starting in 2003 I committed to the idea of creating a luxury apartment in the mall. Over the course of the years to come I systematically coordinated the movement of the core elements that start to define a home.

Internals of Go's new fuzzing system
Go 1.18 is coming out soon. It's a huge release, but native fuzzing has a special place in my heart. Not much has been written yet on how Go's fuzzing system actually works, so I'll talk a bit about that here.

Static B-Trees: A data structure for faster binary search
This section is a follow-up to the previous one , where we optimized binary search by the means of removing branching and improving the memory layout. Here, we will also be searching in sorted arrays, but this time we are not limited to fetching and comparing only one element at a time.

Who is squatting IPv4 addresses?
It’s an established fact on the internet that we have ran out of IP(v4) addresses , and we are starting to see the pressure on obtaining IPv4 space. For example if you want to get a /24 block from RIPE NCC when you sign up as a member, then you are currently looking at a 2 month wait for a recycled IPv4 /24 block .

I've been interested in games programming since I started learning programming as a teenager more than 25 years ago (gasp!) I started with Qbasic and Gorillas.bas, but never understood the code. Of course, I didn't get anywhere at the time, beyond very basic games. I wrote a simple Shoot
