Yes I have been reading about docker and was wondering if docker was a way of getting around what i believe is colloquially called "Dependency Hell"    can you give me more an arm's length philosophical apraisal of where we are now ?

Certainly! Let's take a step back and consider the situation from a broader perspective.
Where We Are Now:

You've been working on setting up Mycroft, a voice assistant, on your system. The process has hit a significant roadblock due to an issue with the distutils module, a Python standard library component that seems to be missing or misconfigured in your environment. Despite trying multiple Python versions, virtual environments, and manual fixes, the problem persists, leading to what is often referred to as "Dependency Hell."
Understanding "Dependency Hell":

"Dependency Hell" is a term used to describe the situation where software dependencies—libraries or packages that your software relies on—become difficult to manage. This can happen for several reasons:

    Conflicting Dependencies: Different applications require different versions of the same library, and the system can't satisfy both requirements simultaneously.
    Missing Dependencies: A required library or package is missing or not correctly installed, causing the application to fail.
    Incompatible Environments: The software might work in one environment but not in another, often due to subtle differences in configurations, library versions, or even operating system versions.

Why This Happens:

In the context of modern software development, dependencies are often managed through package managers (e.g., pip for Python, apt for Ubuntu). While these tools simplify the process of installing and managing dependencies, they can also introduce complexity, especially when different tools or packages require specific versions of the same dependency. When these tools fail to resolve conflicts or correctly install packages, you end up in Dependency Hell.
Docker: A Way Out of Dependency Hell?

Docker is a tool designed to address exactly these kinds of problems by using containerization. Containers are lightweight, portable environments that package an application and all its dependencies together. This means:

    Isolation: Each container runs in its own isolated environment, so the dependencies of one application do not affect others.
    Consistency: Containers are highly reproducible. You can run the same container on different machines, and it will behave exactly the same way.
    Portability: Containers can run on any system that supports Docker, regardless of underlying configurations.

By using Docker, you effectively sidestep many of the issues associated with Dependency Hell. Instead of worrying about which version of Python or which libraries are installed on your system, you can run Mycroft inside a Docker container that has everything it needs pre-packaged.
Philosophical Take:

From a philosophical standpoint, the situation you're facing is a microcosm of a broader tension in software development: the desire for simplicity and ease of use versus the inherent complexity of modern software ecosystems. Tools like Docker represent a paradigm shift, where instead of trying to manage complexity directly (by carefully installing the right versions of dependencies), you encapsulate that complexity inside a container, making it someone else's problem—or, more accurately, making it no longer your problem.

However, Docker is not a panacea. It introduces its own complexities, such as the need to learn and manage containerization concepts. But in exchange, it offers a powerful way to mitigate many of the issues that arise from complex dependency chains and environmental differences.
Where to Go from Here:

Given the persistent issues with the current installation, exploring Docker as a solution is a logical next step. It aligns with the broader trend in software development towards containerization and offers a robust solution to the problems you've been encountering.

If you’re interested, I can guide you through setting up Mycroft using Docker, which should avoid the dependency issues we've faced so far.

How does that sound?

Step-by-Step Guide: Setting Up Your Daly BMS with LiFePO4 Oz

 Fault : I had a flood which shut down the BMS. After it was dried out it worked again ..  I blew up the 24 to 12 volt module probably by having 12 volt on the line but zero on the 24.   Not fail safe - Beware.

The BMS also "forgets" the SOC and thinks it is 100 percent once it comes back up.

Recalibration is :          Cell Characteristics > SCO Set to 50 percent. 

Charge till 28 volts. (Not 28.6 - too high can be set         Protection parameters >sum volt high protect).

SCO Set to 100Percent.  

BMS Software           Can run on Wine (wouldnt using Synaptic) or on Google / Apps Linux. 

Stack Compression?   No One thinks this is necessary.

 Some assert the pile should be restrained with threaded Rod or springs .. the kits supplier thinks it is unnecessary.  If it were i would expect to see a spec in the Operating section.  The Compression Spec is in the destructive batch testing section.

The construction of the battery pack will need to be researched. There needs to be some rigidity / compression in the pack because according to some,  failing this the battery packs will swell during charge and this deformation will damage them.

Gives the dimensions of a test rig and then specifies the maximum pressure (swelling) the cell should exert to pass the test.  I doesnt seem to refer to the design of a working battery pack.

Cold Galv ... 

I tried to use Aluminum speed tape but it was useless. Here is a Gorrilla 4 inch Waterproof tape (expensive) being used as a temporary measure to keep the Coppers from putting a Yellow Sticker (canary) on the Truck. 

The gum in the Gorrila tape is really sticky .. it will take some getting off. In retrospect I would have been better to go straight to the Fiberglass stage.  I have been driving around with the Gorilla tape for a fortnight. The truck was looking very shabby - Cop Bait.

Getting some filler and paint  on it is the next step. Choosing the paint and how to prep the existing crappy paint ... The entire cab is looking a bit forlorn.

 

Gonna get some new license plates too. The Old ones are faded and obviously from the 80s. 

The butyl adhesive is sticky as can be. It will be hard to remove. DONT DO  THIS .. Cover the remaining adhesive with adhesive remover or paint thinner, such as Toulene. Will try prepsol.
