Kubernetes has ostensibly become the defacto leader in the container orchestration world. If you want to run a bunch of containers across multiple nodes in a cluster, k8s is the way to go.
I really wanted to convert some of the web-based services I currently run on Docker on my home network into Kubernetes Deployments. Why? Why not?
I aimed to create a basic setup of 1 master and 2 worker nodes so I needed 3 machines.
As I have written before, I’ve used just about every note solution around. Unfortunately I haven’t found a magic bullet (yet). This post is really an exploration into the pros and cons for my own personal workflow and this the things I find important when managing notes. Hopefully after doing this exploration I can actually settle on one platform for the long haul and stop procrastinating by switching note platforms and writing blog posts about it.
This website is powered by Hugo - a static site generator written in Go. I’ve written about it before and really enjoy using it. Using Hugo, I’ve removed all the obstacles from getting content out there - now it’s just my own laziness in the way…
For years, I’ve had a Jenkins job that builds the site, uploads it to S3 and creates a CloudFront cache invalidation every time the Git repo changes. This all works great, but I haven’t updated the version of the hugo binary in my Jenkins docker image since v0.27.1. The latest version (at time of writing) is v0.44 so I figured I’d just try the new version and see what happens! Will my custom theme make it?
The Steamed Hams Show is a Simpsons podcast by myself and my good friend Jon. In each pod we pick a Simpsons at random and talk about it - often diverging off on hilarious tangents, off-color jokes, and stories from our pasts that in some tenuous way relate to the aforementioned Simpsons episode.
I keep my personal nodes in a bunch of Markdown files inside a Dropbox folder. I’ve used just about every note-taking app there is and ended up settling on this system. It’s served me really well so far.
I have one note at the top level called scratch.md that I use for quickly writing things down when I’m in a hurry. I decided to speed this up even more with this little shell alias:
Redis is very, very good at running as a Highly Available service. It has supported clustering since 3.0.0 was released back in April of 2015. Clustering many redis servers together allows for higher throughput (spreading the load), as well as redundancy (for when servers die unexpectedly).
Here I have assembled some notes about common things you might want to do to your Redis cluster, and how to do them.
Amazon just launched a new service called AWS Certificate Manager (ACM) as part of their ever growing suite of services. The new service allows for more or less one-click creation and deployment of free SSL certificates (yes, free). I used ACM to enable SSL on this very website and it didn’t cost me a dime. Anyone can set up SSL for their own custom domain name in no time at all with this new service.
When using Microsoft SQL Server, enabling Read Committed Snapshot Isolation (RCSI) is one way to prevent reads (SELECT statements) from escalating into full table locks. Depending on your application this can either be a good or a bad thing. I’m not going to get into the why’s and why-nots of each strategy - this is a good article to read if you’re having a hard time deciding which strategy to choose and why.
So let’s say you want to enable RCSI on a fictional database MyDB. This can be achieved by simply issuing the following T-SQL:
ALTERDATABASE MyDB SET READ_COMMITTED_SNAPSHOT ONGO
To check that it was successfully enabled, you can check the System View sys.databases:
SELECT is_read_committed_snapshot_on
FROM sys.databases
WHERE [name] ='MyDB'
If it returns 1 then RCSI was successfully applied, you’re done! Unless…
Documentation is one of those things that’s easy to down-prioritize to the very bottom of your todo list, even though it could be one of the most important tasks that you undertake in your day to day job.
As part of my regular annual website refresh, I decided to take a pretty drastic step and move from WordPress to a static site generator called Hugo. I’ve kept my WordPress install continually up to date since early 2009 and it served me well, but I needed a change. I also went back through the archives and culled all my old blog posts - I only kept the most trafficked and the ones that Future Will might want to reference.
