Rationale: Or why am I bothering to rewrite nanomsg?
I became involved in the nanomsg community back in 2014, when I wrote mangos as a pure Go implementation of the wire protocols behind nanomsg . I did that work because I was dissatisfied with the ZeroMQ licensing model and the C++ baggage that came with it. I also needed something that would work with Go on illumos …

Mainframes as a lifestyle choice
I started working at IBM last year on mainframe compilers with the goal of making mainframes feel a little more modern. Hence, a lot of my time is spent in z/OS . The interface I use to z/OS is Unix System Services (USS, a.k.a. the command line), but if I were up for bucking the whole moderm thing, I could break out…

Static Executables with SBCL v2
It's taken me much longer than I hoped, but I finally have a second version of my patches to build static executables tested and ready to go! This set of patches vastly improves upon the first by reducing the amount of compilation needed at the cost of sacrificing a little purity. Additionally I have created a system…

FreeBSD 15 comes with a new bridging implementation which has native support for VLANs.

During a recent RAID 5 recovery attempt, John made an interesting discovery inside the two failed disks. The plastic ramp that the heads park onto when idle had snapped in the same position on both drives. We don’t know if the heads got damaged first, and then broke the ramps during parking, or if the […]

The PipeWire project is slowly getting popular as it matures. Its documentation is still relatively sparse but is gradually growing. However, it's always a good idea to have people from outside the project try to grasp and explain it to others in their own words, reiterating ideas, seeing them from their own…

Memory Layouts for Binary Search
Binary search is a wonderful algorithm: theoretically optimal, fast in practice, and discoverable by school children playing guessing games. Usually we think of binary search as being applied to a sorted array, and we teach it this way.
