When I joined, I was actually a bit concerned about the narrowness of the new role and the new team. I mean, really… How much […]

Prescriptive software is better than descriptive software
For a while now I’ve been telling people that I want Polypane to be prescriptive, not descriptive. In this article I want to expand on that and explain what I mean when I say “prescriptive”.

Ubiquiti all but confirms breach response iniquity
Last year, I posted a series of articles about a purported “breach” at Ubiquiti. My sole source for that reporting was the person who has since been indicted by federal prosecutors for his alleged wrongdoing – which includes providing false information to the press.

I got the GNU Modula-2 compiler working on OpenBSD

For the clearest example of deliberate data manipulation, see how Walker edits out the data that contradicts his argument from the graph…

Compensation as a Reflection of Values
Compensation: the word alone is enough to trigger a fight-or-flight reaction in many. But we in technology have the good fortune of being in a well-compensated domain, so why does this issue induce such anxiety when our basic needs are clearly covered? If it needs to be said, it’s because compensation isn’t merely…
