MultiBranch Mercurial JenkinsFile
WARNING; this configuration doesn’t seem to delete old builds.
Ever, see; https://issues.jenkins-ci.org/browse/JENKINS-34738.
I’ve worked around it by putting the following blurb near the top of my JenkinsFile
AIY and Pi4j (Voice V1) GPIO Reference
I’m trying to use a Google AIY Voice V1 with Pi4J. I had a bit of trouble finding the pins, so I’m posting this here in case anyone else is looking.
(GZ3)Doom (1993) VR is totally worth it
Someone has ported Doom (1993) to VR and it is as vomit-inducing-awesome in VR as you would expect.
WiFi on a headless Raspberry Pi
I have no idea why the other guides for this take four pages.
Marshalling Gits
This is a quick post-mortem on the three methods I examined for nesting some of our Git repos. In the end, I ran out of time and felt that the diversity of a CS team means that special handling would not produce a time saving benefit for me.
Launch the Docker Daemon from osMac CLI
I’m away and want to start the Docker daemon.1
Git Copy PY Script
I found a set of git tasks was taking non-trivial time to checkout and push between repositories. I couldn’t find docs for a (working) git command sequence1 that pushed branches from one remote to another; so I wrote a python script to checkout a branch to local then push it. Once I was sure that it was running; I could reallocate my attention to something more deserving of my talents.
Scala Extractors
Scala’s extractors and unapply() represent a concept that I haven’t grok’ed until now.
Most demonstrations seem to be too long or use the same types everywhere. Here are my thoughts on the concept;
val a: C = ??? val i: I = ??? i match { case a(f: O) => ??? } This will try to call the below method
class C { def unapply(i: I): Option[O] = ??? } There’s some more flexibility;
Whippet
I made a semi-cache coherent container which provides an Entity-Component-System. These are the bones of contemporary game-engines.
This post is a bit crude; I keep thinking about it then adding features to Whippet instead of writing this up.
Whippet on GitHub Google built CORGI which isn’t (yet?) trying to act cache coherent. It also is more than trivial to build, and suffers from NIH for me. Actually; that last bit isn’t likely to be a problem for most, but I didn’t like their license.
Of Entity-Component-Systems
I made a semi-cache coherent container which provides an Entity-Component-System. These are the bones of modern game-engines.
This post is largely a gooey weasel opinion piece. It started as an introduction that grew out of control. So, for now, it’s just a bit of rambling while I clean-up the documentation for my tool.
Of Entity-Component-Systems Among other things, Jason Gregory’s book Game Engine Architecture discusses the concept of a data-driven architecture for game software.
