Don't Build APIs
My first job at Microsoft was providing developer support for the early Windows SDKs. To do my job well, I spent hours studying the Windows SDK documentation, the Windows source code, and writing sample applications. I then spent hours poring over customers’ (such as Lotus, WordPerfect, and Computer Associates) code…

Routing the Technical Interview
The interviewer couldn’t help but notice her name, Nephele . It sounds Greek. But he didn’t ask, not wanting to get off on the wrong foot with the promising candidate. He made a mental note to look up the name afterwards.

Who Says C is Simple? (2010)
When I (George) started to write CIL I thought it was going to take two weeks. Exactly a year has passed since then and I am still fixing bugs in it. This gross underestimate was due to the fact that I thought parsing and making sense of C is simple. You probably think the same. What I did not expect was how many dark…

Faster Sorting with Go Generics
Recently, a new set of sorting functions has landed in Go's golang.org/x/exp/slices package [1] . These functions leverage Go generics to provide a more ergonomic API for sorting (without requiring users to implement sort.Interface ), and also deliver a nice performance improvement, as the CL demonstrates.

Self-Replicating Functions
These are notes I’m creating for myself as I explore functions \(f\) that can be written as a sum \(f = g_1 + g_2\) where \(g_1\) and \(g_2\) are shifted and possibly reflected versions of each other, both strongly resembling the original function \(f\) . When a function \(f\) has these properties, I informally call…

Why code review beats testing: evidence from decades of programming research
tl;dr If you want to ship high quality code, you should invest in more than one of formal code review, design inspection, testing, and quality assurance. Testing catches fewer bugs per hour than human inspection of code, but it might be catching different types of bugs.

Learning Clojure: comparing with Java streams
This is the 6th post in the Learning Clojure focus series. In general, one learns by comparing to what one already knows: I’m learning Clojure in that way. Coming from a Java background, I naturally want to use streaming features. So, what would be the Clojure counterparts of Java’s functions filter(), map(), etc.?
