Severance and FedRAMP - keep them separate

Not long before starting my career break to help out with family, I had a social catch up with some work colleagues via Zoom and the conversation looped into what TV shows people have been watching lately... (do we still refer to things as TV?). Severance got a mention, so a few days later I got drawn into starting an Apple TV subscription to find out what it was all about.

This post is going to be short and sweet, that may limit it to an inside joke or "Were you thinking what I was thinking?" as I don't want to offer up any spoilers about the Severance, or FedRAMP.

I just hope nobody takes inspiration for life to immitate art, by having the Severance approach to work/life balance be applied to meet a level of FedRAMP isolation.

Applying AI to software development can be like following SatNav

Trying out a different navigation system

A month or so ago I upgraded to a car that has a SatNav system included, so I have been trying to use that instead of the Maps app on my phone. My experiences with it so far have generally been good, but it is far from flawless - a bit like Artificial Intelligence (AI) in software development.

As context, my previous vehicle was not too old to include SatNav, it just hadn't been set up with English language or New Zealand maps - one of the down sides of having a second hand vehicle that originated in Japan.

Flawed or incomplete information

Driving around central Christchurch can be a bit challenging at times as various roadworks are underway, leaving streets closed off or narrowed down to a single lane. It could be reasonable to expect that a basic navigation system might not have up to the minute awareness of those closures and restrictions. However, something that I did not expect to encounter was the navigation system advising me to expect a roundabout where no roundabout exists. This hasn't just been a one off anomaly, so I am having to glance down at the map from time to time to understand whether I should be preparing to turn at these traffic lights or further along.

As I become more accustomed to the prompts coming from the SatNav, I expect that I will be more aligned with the time and distance ahead that the guidance is expected to be related to.

Routing with unclear preferences

I'm not sure why, but on a recent long distance drive the guidance system wanted me to turn off the main highway to go inland to some unfamiliar roads. Normally I would be curious enough to take a little detour and see a different part of the countryside, but on this occasion I had a kitten as a passenger in the back seat so I wanted to stay on the familiar and direct route.

There may have been some marginal difference of total road distance, but I don't know if the inland roads would have been of the same sealed quality as State Highway 1. The only time that I have needed to detour inland around that part of the country before involved gravel roads, where my comfortable driving speed is much lower.

Lower involvement results in lower recall

If I am not actively engaged in the navigation process then I am less likely to remember details of the route for future journeys. If I didn't make an active decision to turn off at a particular place, I will be less likely to absorb that information and have it available for use in the future.

Generating code with AI is like using SatNav

When it comes to software development, I believe that we should be treating artificial intelligence systems with a suitable amount of caution and awareness of the potential limitations and flaws.

I have used AI to generate small one-off utility apps, as well as to produce snippets of code for production systems that process millions of data records every day. Just like we have checks and balances in place to test and review code produced by human developers, I would not allow fully AI generated code to drive my production systems...  ...yet.

Between the chair and the keyboard

The person driving the AI still needs to be around for awareness so that what is being produced will be fit for purpose - meeting the "ity" considerations, such as:

  • functionality 
  • scalability
  • security
  • stability
  • durability
  • flexibility
  • ...

Ethics, and compliance with laws and standards are also aspect that will continue to require people being involved to be held accountable for.
