restore HPC content, remove Carpentries content

[tkphd]

This PR aims to remove material specific to The Carpentries, such as institutional sponsors and donation opportunities, and replace boilerplate or Carpentries-specific copy with HPC Carpentry equivalents.

The table enumerating HPC Carpentry lessons has been restored.

The Help Wanted page has been filtered to only show issues from HPC Carpentry lessons.

This looks like a good set of revisions to help the HPC lesson stand alone Thanks!

Overall I think this is really nice trimming of the site. I'd be concerned that it's a bit too agressive in some parts and removes some useful templates that we could use in the future.

[tkphd]

Thank you for the feedback, @reid-a and @ocaisa. Before responding to the individual comments, I want to summarize my mindset when I made these sweeping, often deep-cutting, changes.

HPC Carpentry is a nascent organization, and we aspire to join The Carpentries. It remains to be seen whether that will occur, and if it does, on what timeline. With that in mind:

1. The repository this one is based upon is CC BY, so we can copy all of it.
2. The upstream repository is actively maintained by a larger organization, and subject to change -- often for the better -- that we can synchronize with as needed.
3. When deploying the site to represent ourselves, it is important that we do not misrepresent HPC Carpentry as a formal member of The Carpentries.
4. Parts of the upstream website interface with AMY, where contributors opt in to be publicly listed. That permission is granted to The Carpentries, not to HPC Carpentry. It is unethical to include those parts.
5. We are a small team, and each additional line of code represents a maintenance burden.
6. If a feature, page, or parameter is of immediate use, it stays.
7. If a feature, page, or parameter might come in handy -- let the upstream maintainers improve those parts and, when the time comes for us to include them, we can pull the latest versions.

I think I concur with @tkphd that, when we become official, we'll want to match up with the then-current Carpentries scheme, which may not match the material that's been removed here. FWIW.

[ocaisa]

I think removing comments that potentially provide people with quick and useful information increases the maintenance effort rather than reduces it. I'm not sure it is so realistic to believe that anyone editing this repo will automatically cross-reference with the upstream site.

[tkphd]

Valid points, @ocaisa, thank you for the patient replies. I will revise.

[tkphd]

For fellow travelers, the back-and-forth between @ocaisa (who originally ported this website, and is the expert) and myself (not a Jekyll noob either) is a healthy exchange, and at the end, we'll have a better website for it. This is why we have pull requests and peer review, rather than making changes to the production website directly. Plus, it looks like this has spurred some awesome upgrades -- much appreciated, Alan!

[tkphd]

OK, @ocaisa! I've done my best to resolve your detailed comments & objections. Site build locally, and now displays our shared Google Calendar and presents @megan-guidry as our Regional Coordinator for New Zealand. Let me know what you think.

[ocaisa]

At the moment this is a manually curated file (but that will change with #25) so this needs to remain commented out or we will pull in all the Carpentries Incubator information

[ocaisa]

This is great, thanks a lot for spending so much time on it @tkphd !

[tkphd]

Of course, @ocaisa -- happy to do my part!
