The hot tub is not only filled, it is hot. It hasn’t killed me, yet. I did kill my network swapping out the firewall. Tip: It doesn’t matter what your iptable forwarding rules are if IP forwarding is not enabled. Next steps: Renumber the virtual machines and add the names to PiHole.

Tech Update
The cluster is sitting there doing its thing. I figured out why Cassandra is such a memory hog: It queries the system memory when it starts and allocates 3/4 of it. Oh sure, there is a limit: 18GB. I haven’t done anything about it, but now I know. The stuff I’m writing that uses theContinue reading “Tech Update”
I Can Quit, Anytime
The bottom glowy bit just arrived. I think it adds a nice symmetry. There is no such thing as RGB addiction. Really.
Cross Disciplinary
This seems to fit me. I found it at the PowerLine week-in-pictures, so I have no idea how to attribute it. And there is a word for words that are spelled the same but pronounced differently (e.g. “record a record”), but I don’t remember what it is; “grafonym” or “homograf” maybe? I had never realizedContinue reading “Cross Disciplinary”
gogs up
gogs is a “GO Git Server” that (supposedly) runs just about anywhere. It runs fine here. I wanted source control locally, and a bit more “control” than just a git init local directory. There were a few issues: I wanted the repository directory to be on a guest/host shared directory/folder (so Windows backups would getContinue reading “gogs up”
Computer Speakers
Those count, right? Very non-stereo, but there is no room on the right side of my desk for one of those. There will be upstairs – I’m building it into the desk space; they’ll hang on each side of the monitor. As always, it was an adventure with a simple solution. Why do they alwaysContinue reading “Computer Speakers”
Logstash Up
This is getting easier. Logstash is running and so is the Prometheus exporter for it. Kibana, on the other hand, is a nightmare. I can’t get it do anything other than spew security warnings. I made them go away – by adding “basic security” to Elasticsearch and Kibana – and it broke all the logstashes.Continue reading “Logstash Up”
Gone Public
It’s not quite ready, but at the request of an interested party, I made the github repository public. One more (successful) rebuild-from-scratch and I’m calling it good. In addition to getting Pulsar Manager running, finally, I wrote (trivial) tests for both Pulsar and Cassandra. They work! BLEK is still missing. Jaeger is a possibility. But,Continue reading “Gone Public”
Rebuilt!
A few bobbles, but I rebuilt the whole thing from instructions. About three pages of instruction-update notes, which I will deal with later. It’s bed time, again. [WordPress did want larger featured images]
Cassandra Up, Again
A three node, three rack, one data center Cassandra cluster is running! It has a few configuration values that require IP addresses, yuck! All the cluster software is up! What’s left? Install the Docker monitor for Prometheus (cAdvisor). Install BLEK. Cross-reference build scripts against written instructions. Throw it all away and rebuild from scratch. MakeContinue reading “Cassandra Up, Again”
