To go along with the Embedded Systems Analysis material I've been developing, I wanted to have slide decks for each section. I originally started writing the material in markdown as a way to enforce more accessibility. Using something like PPT would betray that notion and so I began to look at other options...
I wanted to install Windows 11 on my desktop today. In preparation for this I specifically ordered a new M.2 SSD to install Windows on. In the back of my head I thought about backing up my old M.2 SSD or buying some device that would allow me to read the SSD through some other adapter. Ultimately I didn't do anything because I had recalled I had a second M.2 slot on my board and in a pinch I may have to just switch back for a backup if there were files from the old install.
Went to go build an old dockerfile to look at the state of some files in an installation. I was suddenly getting all kinds of errors ... turns out my machine automatically updated docker where BuildKit is now the default. You can go look up BuildKit and all the wizbang gizmos it comes with. I just wanted to be able to build my legacy
Dockerfiles the way I always had and now I can't?! You had one job Docker!
I've been down this road many times, but this time I became a little more determined to get through it. I'm talking about using ESM/ES6/ES7 with test frameworks in NodeJS to do some integration / functional testing of an app backend I've been writing.
The primary reason for my writing this blog post now is because I intend to post the Inform section incomplete. I'm tired of coming up with reasons to not post what I've already written and I'd rather have what little's been done available sooner than later. That said, this is a early access sort of thing and should evolve over the coming weeks into something more complete.
As an application developer, I wanted to get more of an appreciation (and independence) of functions as a service (faas) (i.e. serverless). There is a product called OpenFaaS that is a framework for setting up your own serverless provider. This is akin to setting up your own AWS Lambda, Azure Functions, or Firebase Functions. The trouble is that I felt I had already wasted enough time fiddling with Kubernetes and other related technologies that frankly were too much for my needs.
But out of nowhere I ran into
faasd is a light weight version of OpenFaaS services that allows me to throw up functions on a VM or even a RaspberryPi. Of course I dived right in, thinking this would be as simple as a download, install, run kind of operation. Oh how I was wrong. Even with its light weighty-ness, it requires a pretty vast knowledge of systems and networking to get going correctly. Additionally, this is a very immature product that doesn't have the friendly and polished UX that I was hoping for. None the less, its what we've got and I was determined to get it going.
I was recently taking some training through work. In this training I was provided a VM that contained all of the course labs and tools. As an avid VSCode user I naturally pointed my Remote SSH extension at the VM to remotely connect via VSCode.
The moment I entered my credentials I got a message like:
VSCode is not supported on the target architecture.
Sometimes when you work in different environments there are different security policies that inevitably make my job very difficult if not damn near impossible. I can usually figure out something out that is incredible inefficient and just let the customer pay the additional cost. I ran into one of these environments the other day where I was given a VM to perform my development from. This VM was pretty locked down, but it did provide me sudo to
docker. I thought, "Great, as long as we have
docker, we should be good!" ... oh boy was I wrong.
Interested in building something that doesn't require a laptop or TV for Raspberry Pi input/output, I recently purchased a TFT Display with some input buttons. It additionally included a very profession looking aluminum case with real metal button and some other goodies.

Looks like this site is doing that thing where its lost its initial motivation. I have continued writing but haven't been able to actually publish due to a number of personal issues. In the spirit of public learning and personal documentation in general, I've decided to write up a quite update on some of the things I've been working on.
