Probabilistic inference is a widely-used, rigorous approach for processing ambiguous information based on models that are uncertain or incomplete. However, models and inference algorithms can be difficult to specify and implement, let alone design, validate, or optimize. Additionally, inference often appears to be intractable. Probabilistic programming is an emerging field ...

Rust aims to build a solid foundation for building safe software systems faster. We can ensure fewer mistakes enter our code base with immutability by default, no concept of null, and proven memory safety.

We know how to write bad code: litter our programs with casts, macros, pointers, naked new and deletes, and complicated control structures. Alternatively (or additionally), we could obscure every design decision in a mess of deeply nested abstractions using the latest object-oriented programming and generic programming tricks.

Philip Wadler, Professor of Theoretical Computer Science at the University of Edinburgh, contends that the foundations of computing lay in a coincidence: Church's lambda calculus (1933), Herbrand and Godel's recursive functions (1934), and Turing's machines (1935) all defined the same model of computation. He gave this lecture on the occasion ...

Why is the overwhelming majority of common networked software still not secure, despite all effort to the contrary? Why is it almost certain to get exploited so long as attackers can craft its inputs? Why is it the case that no amount of effort seems to be enough to fix ...

The Clojure ecosystem, we're told, is made up of small, composable libraries. In practice, though, it's all too common to find that two libraries simply will not cleanly compose. This typically will lead to another library that does the same thing, but in a subtly different way. Sometimes this is ...

The time has come to think concurrently. Traditional software concurrency management leads to non-deterministic race conditions and deadlocks that are hard to reproduce and debug, leading to unreliable software. That means it's time to introduce math. Tony Hoare's paradigm of communicating sequential processes, or CSP, is not only a robust ...

JavaScript programmers like to use words like, “event-loop”, “non-blocking”, “callback”, “asynchronous”, “single-threaded” and “concurrency”. We say things like “don’t block the event loop”, “make sure your code runs at 60 frames-per-second”, “well of course, it won’t work, that function is an asynchronous callback!” If you’re anything like me, you nod and agree, ...
