You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
An excerpt from my book Coders at Work that I frequently find myself wanting to cite mostly because I get a kick out of someone having standing to call BS on Dijkstra:
Recently my friend Lars Hupel and I had a discussion on why formal methods don’t compose well. You can read the conversation here. We focused mostly on composing formally-verified code. I want to talk a little more about the difficulties in composing specifications. This is half because it’s difficult for interesting…
The Spaghetti Code Conjecture says that Busy Beaver programs ought to be, in some sense, as complicated as possible. Scott Aaronson puts it this way:
A long-standing objection to making bulk changes to code using automated tools (e.g. to conform to a given code style) is that it clutters the output of git blame. With git 2.23, this does not have to be the case anymore! In this post I will start by explaining the value of git blame and […]
Homoiconicity (code as a data structure) is one of the pillars of the Clojure language. It gives the extensibility and flexibility to the language.
I've spent a little more than a month working with Git now. I can honestly say that while there are many things that I like about Git, there are just as many things that I personally find to be a pain in the butt. Submodules specifically have managed to be a thorn in my side…
Many people must have heard this quote (by Phil Karlton) many times: There are only two hard things in Computer Science: cache invalidation and naming things. Two days ago, Nick Tierney mentioned it …
This is a little sed challenge that ocurred to me somewhat recently, when I wondered how many weeks were between 2 dates. Of course, I just looked at the calendar and counted, but then I wondered what kind of sed script I’d need in the middle of a cal -y | ... | wc -l pipeline to get the same answer.
During a recent audit, we discovered that some third-party Chromium based browsers were able to integrate Google features, such as Chrome sy...
When it rains it pours. After making a splash with D , 1 I remembered that some time ago I began an attempt to bring the GNU Modula-2 compiler to OpenBSD . Because why not? Modula-2 is a language that exists and has compiler implementations. I guess my goal is to bring all the languages and compilers to OpenBSD. And…

You see, there are two memory accesses per one character of the input string (at average). Hence, the total number of all memory accesses can be len*2 at worst.
There’s not a whole lot on TLA+ technique out there: all the resources are either introductions or case studies. Good for people starting out, bad for people past that. I think we need to write more intermediate-level stuff, what Ben Kuhn calls Blub studies. Here’s an attempt at that. Most TLA+ properties are…
