The August 2016 Lisp Game Jam just wrapped up at the end of last week. I had some free time so I decided to take part, but I did something a bit different. Instead of making a new game I ported an existing one ( Silt ) to Common Lisp.
It's been a while since I've last rewritten my favorite lexical analyzer :-) That post is the last in a series implementing a lexer for the TableGen language in a variety of programming languages, using multiple techniques. The last lexer written, in Go, was very fast indeed - processing 1 MiB of source in about 20…
Joe Bertolami's portfolio and blog covering artificial intelligence, game development, computer graphics, data compression, and more.
My GPU is the integrated Radeon Vega 8 that comes with my AMD Ryzen 7 5700G CPU. I tell you this so you know that my workstation is not a graphical computing powerhouse. It is, in fact, quite weak. To its credit my integrated GPU shows up as 48% faster on UserBenchmark than the GPU in my low end hardware target; a…
I recently spent some time going through the amazing nand2tetris course, and assignment #9 is to implement something with the Jack programming language that runs on the Hack computer. My friend encouraged me to try writing a raytracer, which is an algorithm that generates physically realistic images by simulating…
Barbara Liskov pointed us in her talk at Heidelberg Laureate Forum to some interesting “must-reads” for computer scientists. The talks will be available here: http://www.heidelberg-laureate-forum.org/ . I strongly recommend to watch many talks – including hers.
The virtual machine? Yep, but not the Java Virtual Machine.
We all know that when designing and operating applications at scale, it is persistent state management that brings the most difficult challenges. Delivering state-free applications has always been (fairly) easy. But most interesting commercial and consumer applications need to manage persistent state. Advertising…

Using one of the test cases from the previous post , I examine what affects AFL's ability to find a bug placed by LAVA in a program. Along ...
Being a self-described programming-language programming language is an ambitious goal. To preserve predictability while permitting linguistic extension, Racket comes equipped with a module system carefully designed to accommodate composable and compilable macros . One of the module system’s foundational properties is…
Paul Khuong's personal blog. Some Lisp, some optimisation, mathematical or computer.
Programming language features are never orthogonal.
Traditionally C++ has been seen by many (and you know who you are) as just plain bad: the code is unreadably verbose, error messages are und...

Rust doesn’t have namespaces in its package management system. It’s often viewed as a bug. But it’s not a bug, it’s a feature! While there are negative aspects of a flat package registry, there are also real benefits. Stability, continuity, and unity (discourages forks and fragmented identity)…
Most C programmers also know to avoid the legacy strcpy() and strcat() functions, as these commonly introduce buffer-overflow problems. Instead, C programmers should use the newer strncpy() and strncat() functions, which check the size of the buffer they're copying data into.
Firstly this is not just my effort but my team and organisation. Secondly the usual rules apply, this is expert advise and what works for me will very probably cause your whole production stack to blow up and kill people. Lastly this is long so skip to the bit you care about or come along and chat at QCon London 2012
If you've ever seen a discussion of functional programming languages on the Internet, you'll have probably noticed one talking point in particular that comes up frequently. For the sake of generalization, let's make up a hypothetical functional programming language called Gooby. In these discussions, often someone…
In this essay, I will perform the logical fallacy of argument from authority (wikipedia.org) to attack the notion that large language model (LLM)-based generative "AI" systems are capable of doing the work of human programmers.
It's not about technology for its own sake. It's about being able to implement your ideas.
Wow, college was such a waste of time ... when did you ever invert a binary tree outside of an interview? Honestly I never inverted a binary tree in college either ☹️
It's a justifiable copout, but it's still a copout.
