How to zero a buffer

Now, we don't want to truly change the observable behaviour of our software — but fortunately the C standard has a more liberal concept of "observable" than most people. In particular, the C standard states that the observable behaviour includes accesses to volatile objects . What is a volatile object, you ask? It is…

Sana'a

The scariest thing I'll see in Yemen looms up at me before the plane has even landed. I have dozed my way from Abu Dhabi across most of the Arabian Penninsula, including the Empty Quarter, that vast uninhabitable sandbox in the interior were they didn't even bother to put in borders until fifteen years ago. That just…

Call me maybe: RabbitMQ

RabbitMQ is a distributed message queue, and is probably the most popular open-source implementation of the AMQP messaging protocol. It supports a wealth of durability, routing, and fanout strategies, and combines excellent documentation with well-designed protocol extensions. I’d like to set all these wonderful…

How My Book Launch Went

Greetings, superfans! When we last tuned in , I was just about to “launch” my self-published book . I put that in quotes because it’s an awfully serious-sounding word for what was really just doing some clicking on my laptop.

The difficulty in learning Clojure does not stem from its syntax, which happens to be extremely simple, but from having to learn new methods for solving problems. As such, we'll focus on understanding the core concepts and how they can be combined to solve problems the functional way.

Trust but Verify

It is becoming increasingly difficult to trust the privacy properties of software and services we rely on to use the Internet. Governments, companies, groups and individuals may be surveilling us without our knowledge. This is particularly troubling when such surveillance is done by governments under statutes that…

Interactive Programming in C

I’m a huge fan of interactive programming (see: JavaScript , Java , Lisp , Clojure ). That is, modifying and extending a program while it’s running. For certain kinds of non-batch applications, it takes much of the tedium out of testing and tweaking during development. Until last week I didn’t know how to apply…

The Computer Graphics Library

Back in the 90s, one book was ubiquitous in the world of Computer Graphics. Commonly called "The CG Bible", Computer Graphics: Principles and Practice gathered a huge part of the knowledge of the time. It was commonly referenced by the best programmers of that era in interviews and articles . By 1998, the book…

TLS Symmetric Crypto

At this time last year, the TLS world was mostly running on RC4-SHA and AES-CBC. The Lucky 13 attack against CBC in TLS had just been published and I had spent most of January writing patches for OpenSSL and NSS to implement constant-time CBC decoding. The RC4 biases paper is still a couple of week away, but it's…
