It’s running on names, now. I’ve also restructured the files with the intent to upload it all to github as one package and documented a step-by-step guide, getting this far, at least. Note that I didn’t lose the Zoo data. It’s also generating log files, now, so they can be picked up by logstash (someday)Continue reading “ZooKeeper Up – Again”

DNS Up
BIND doesn’t seem to have a logo, so I picked this. On the off chance anyone sees it, I picked a watermarked picture in the hopes of not running into copyright issues. Aside from the clever name, it’s an interesting site. My virtual machines now have names (and static IPs) and can see each otherContinue reading “DNS Up”
Learning 2 Bake – from Scratch XVIII
There is good news, just news, bad news, and meta news on the baking front. Meta News The Kitchen Aid from G*d died. I hadn’t planned on immediately replacing it, even though I needed to bake some cookies for a bring-some/share-some thing; one batch of cookies by hand is hardly onerous. And there it was,Continue reading “Learning 2 Bake – from Scratch XVIII”
Pulsar Up
I have no idea if it is working and I’m going to bed before trying to find out. It is started. Three VMs each with a ZooKeeper, BookKeeper, and Broker running on them. Once I get it tested, I’m definitely arranging this properly and putting it on github. This should not have been so difficult.Continue reading “Pulsar Up”
Learning 2 Bake – from Scratch XVII
It’s been so long, I had to look up the number. It is gloomy and chilly today. What better time to bake cookies! The Laird has been buying Artisan Kettle dairy free chocolate chunks for our kibble. Is anyone surprised that there is a chocolate chunk cookie recipe on the back? Artisan Kettle Extra DarkContinue reading “Learning 2 Bake – from Scratch XVII”
Social Praxis?!?
Who uses such expressions? Because they are screaming about Kyle Rittenhouse, I heard about MEChA (Movimiento Estudiantil Chicanx de Aztlán). I was curious, so I looked them up. I don’t recommend it. Their website is a word salad nearly devoid of meaning. As an example, using a sentence that actually parses:MEChA chapters are often theContinue reading “Social Praxis?!?”
Booster Lifetime
The SLS is at risk of another delay. Apparently, once stacked, solid rocket boosters have a limited lifetime and NASA will soon be running up against it. I have no idea why, so I asked. Just a comment tracking post so I don’t forget to go back and see if anyone answered.
ZooKeeper Up
Was that a nightmare. They refused to talk to each other. It would have been easier if I had had any confidence in the VM network, but since I didn’t know if that was failing or not, there were many more variables. The answer was simple, but “simple” does not mean “easy”. There are fiveContinue reading “ZooKeeper Up”
Python Adventures
I cheated. I’m running Cassandra 3.11 in docker containers. The shell (cqlsh) is a Python script that runs fine in docker, if you can figure out how: I want cross-VM access, so I need to run it outside of docker. I haven’t figured out how to give Virtual Box VMs DNS names, so I usedContinue reading “Python Adventures”
Zoo & Book Up
Wow. That was harder than Cassandra and I still haven’t started on Pulsar. A few notes: ZooKeeper needs persistent volumes. BookKeeper expects some metadata to be there. If you don’t persist it, you end up with race conditions when they start (as each one tries to bootstrap the metadata). Get the right image from dockerhub.Continue reading “Zoo & Book Up”
