Talks

I’ve done a lot of stuff in the last half of 2017, but not much of it has made it here. Here’s a roundup of things published/spoken/embroidered/etc in other places:

MirageOS is a collection of libraries and a system for assembling them into unikernels. What happens if you want to make changes to those libraries and test them with a new unikernel?

Say, for example, I have a static website (like this blog) that I build in MirageOS. I want to make some changes to the TCP implementation against which the blog is built. In order to do that, I need to do all the following:

• figure out which module to change
• figure out which package provides that module
• get the source for that package and instruct the package manager to use it instead of the release
• make changes
• reinstall the package with your changes
• rebuild the unikernel completely
• see whether changes had the desired effect

Here’s a quick primer on how.

As a result of great encouragement from colleagues and friends, I gave a few talks in September.

Persistent Networking with Irmin and MirageOS, which I gave at the OCaml Workshop, is a talk on sticking a persistent database into various levels of the network stack. (It includes demonstrations from What a Distributed, Version-Controlled ARP Cache Gets You, as well as an Irmin-ified NAT device that I haven’t yet written up here.) The slides for my OCaml Workshop talk are also available.
