Max out CPU on Linux

Jun 6, 2019

There are times when you may have a need to test server performance when investigating an issue or doing a predictive analysis. I learned an easy way to do this on Linux using the built-in ‘yes’ command. From the man page for the ‘yes’ command: NAME yes - output a string repeatedly until killed This does exactly as it says and will consume the CPU unless it is controlled or killed.

Host Plex on AWS and Wasabi

May 5, 2019

Wasabi Storage Storage is one of the costliest options in the cloud and probably the biggest deterrent to migration. Fortunately, a handful of contenders are changing the game and breaking into affordable options for personal budgets. One of these companies is Wasabi. I have embraced the AWS platform, so on the surface this appears to be in opposition to that. Maybe it is, but Wasabi utilizes AWS S3 on the backend with a pricing strategy fit for personal as well as business use.

Imprints

May 5, 2019

There are 2 imprints on the pillow my wife uses for the twins. These imprints are from their heads and bodies as they’ve grown and been laid down in the same place for months. We are all like the pillow receiving imprints on our lives from those around us. Some people are around just a short while and we barely notice. Others we invite back repeatedly and the relationship can last for years creating deep and long lasting effects.

Facebook Is Like A Public Restroom

May 5, 2019

I was feeling a little snarky today and this realization hit me: Facebook is like a public restroom Here me out: Facebook is basically a public service that everyone “needs.” Some people refuse to use it. Others only use it when they are forced to, and others actively seek it out and use it routinely. Even those that don’t use it still can’t completely avoid it as everyone talks about it, they see its ads and logo everywhere, etc.

Clear CloudFlare Cache from Lambda

Apr 4, 2019

As I’ve stated in previous posts, I currently use CloudFlare as my CDN. There are several reasons for this that I won’t go into now. One of the “ToDo’s” on my list has been to clear CloudFlare’s cache when I upload new content to my blog. I was finally able to spend some time and get that done. CloudFlare API To start things off I reviewed the doc for the CloudFlare API.

Change Outputs on the Nord Stage 2

Apr 4, 2019

The Nord Stage 2 has four audio outputs as shown here: You can send the various sections (synth engines) of the Stage 2 to the different outputs. This allows for more control over the mix and EQ at your output whether it be a recording bus, personal monitor, or live sound board. It’s a rather simple process. Shift -> System Use Program Page buttons to go to Synth Outputs Scroll to change to the desired output

Types of Keyboards

Mar 3, 2019

Having over 12 years of keyboarding experience I’ve played on numerous boards and have come to realize the various differences and nuances between the types. There are formal definitions out there and this list is probably not exhaustive, but it reflects my personal opinion. If you are reading this and are unfamiliar with keyboards this is a good place to start. Midi controllers: Make no sounds on their own. Plug them into another device such as a keyboard or laptop to generate sounds.

Case Study: SMTP Limits

Mar 3, 2019

It’s important to know your limits. In this case study we find a situation stemming from SMTP being throttled. This is part of the packet capture I received: The top lines show the previous conversation ending. SMTP successfully sent 3 messages. After the 3rd message the mail server stopped responding and retransmits began. This pattern was repeatable. More than that it was repeatable from other EC2 instances. The only thing between the EC2 instances and the mail server was a router and a firewall.

Alexa App for Kids

Feb 2, 2019

If you refer to this post, you’ll see that one of my objectives for this year was to develop an Alexa app for my kids. Well, I am happy to report this objective as completed. The cover art and the image below show the high level architecture. The app idea actually started based on something I was doing for my kids that they really took a liking to. Unfortunately, for this post it might be an idea that I could actually publish and potentially monetize.

How I Moved From Wordpress to S3

Jan 1, 2019

Being that I recently took the plunge to a static site hosted on AWS S3 I thought I would create a post outlining the high-level process for future reference. There are quite a few blogs in the interwebs outining this process, but if this helps someone else too then it’s a win-win. If you are curious as to WHY I migrated, you can find a short bit about that in this post.
