An interface can be thought of as a contract between the system and the environment. In a computer program, the 'system' is the function or module in question, and the 'environment' is the rest of the project. The interface formally describes what can pass between the system and the environment. An 'implementation'…
A couple of months ago I set out to investigate some orchestration tools for Docker containers. I.e. something that would help us schedule Docker containers onto nodes in a cluster and make sure that our services stays up in case of various failures. But let’s start at the beginning, why would we need this in the…
Stevan Harnad’s “Subversive Proposal” came of age last year. I’m now teaching students younger than Stevan’s proposal, and yet, very little has actually changed in these 21 years. On the contrary, one may even make the case that while efforts […] <a class="more-link"…
Today I set out to the task of upgrading a set of views crafted with the React library. The upgrade was necessary because one part of a view using React stopped working in Chrome Version 48.0.2564.116 (64-bit). I don’t know why this happened, I didn’t find anything related to it and as it stands this was probably the…
It’s tough for an aspiring Iron Man to work on creating their personal AI assistant on the weekends. Like any other time-pressured inventor without a PhD in computer science and linguistics, …
I mentioned recently, buried in a post about UI changes, that Twitter’s latest earnings report included this bombshell: We are going to fix the broken windows and confusing parts, like the .@name syntax and @reply rules, that we know inhibit usag

Remember Galton’s experiments on visual imagination? Some people just don’t have it. And they never figured it out. They assumed no one had it, and when people talked about being able t…
In my last blog entry LLand LR Parsing Demystified, we explored LL and LR parsers from ablack-box perspective. We arrived at a model for these parsers whereb...
In celebration of the detection of gravitational waves, Stephen Wolfram looks forward and discusses what technology black holes could make possible.
You go into work and discover that a coworker isn't happy with some code you wrote because they don't understand it. They go to your manager and tell them that you're being a problem by writing code they don't understand. Your manager, being very skilled in conflict resolution, makes a technical decision to avoid…
About 18 months ago I had a really cool idea: What if we could communicate with people who are high on LSD in such a way that sober people can’t understand?* I call this idea psychedel…
How should we go about making typographic laws, rules and guidelines for the web?
In what may be judged in years to come as a moment of madness, I have volunteered to be the primary maintainer of the Perl CGI module (CGI.pm). For the non-technical readers of this post: CGI.pm is a few thousand lines of code that in the mid to late nineties, and even some years later, was helping many websites…
