I'm pleased to announce that this past weekend I released the first version of my implementation of the SP (scalability protocols, sometimes known by their reference implementation, nanomsg) implemented in pure Go. This allows them to be used even on platforms where cgo is not present. It may be possible to use them in playground (I've not tried yet!)
About two years ago Joyent began offering Linux instances, running under KVM, stored on ZFS, and secured by Zones (“double hull virtualization”). Since then, I’ve been doing more and more work on Linux performance as customers deploy on these instances. It’s been fascinating to work on both the illumos and Linux kernels at the same time (a Linux guest in an illumos host), with full stack visibility of the guests, and hypervisor, down to metal.
My dislike for C++ is well-known by those who know me. As is my lack of fondness for Perl.
I learned that Logitech has brought the Squeezebox product line to end to life. I’m not prepared to replace (or research what might replace) our current audio infrastructure, so I’m experimenting with a piCorePlayer install to see if a low cost, Raspberry Pi solution can solve this problem, much like OpenSprinkler has addressed home irrigation.
