Domain Driven Design

Ubiquitous Language: the language used by everyone to describe the concepts spoken about (so that they are all on the same page)
Bounded Context: "a semantic contextual boundary"; within the boundary, each component has a specific meaning and does specific things
Domain:
- Core Domain: the strategic scope which is core to the business/software product
- Sub-domain: a sub-part of the overall business domain (supporting is ancillary to the core, but worth implementing in-house, whilst generic isn't, e.g.: user invoicing)
Domain Event: a record of some significant event occurring in a bounded context, which can be consumed inside the originating bounded context or by other bounded contexts
Aggregate/Entity/Data: a high-level type or model (it may be composed of entities and value objects)
Command: an operation which causes a domain event

Debugging `capybara-table`

Bumping Nokogiri to 1.11.5, caused our tests around HTML tables to start failing with ERROR: Recursion limit exceeded. The change that caused this is in commit [#9fcb7d][1] (see also: [the full set of changes][2]), where the recursion limit is restricted to 500 (see: [libxml2 commit][3]), which is how it started happening with this Nokogiri update.

In investigating what was causing this to recur, it seems like we don't need all of capybara-table, as [enough is already included in Capybara itself][4].

I did consider just dropping the dependency, but the Matcher/Renderer classes are key to the usability of our tests — I even tried not using them but trying to factor out the dependency was a horrible experience.

My next step would be to try and switch the Capybara selector that CapybaraTable::RspecMatchers uses to the ones already in Capybara: [table.rb][5] and [table_row.rb][6]. This might be as simple as vendering the RspecMatchers.rb file into the project and seein

Drafts → Basecamp / Trix Rich Text Fields

Problem: Copying text with reference links as Rich Text from Drafts into Basecamp mangles all of the formatting.

Solution:

Inspect Element on the editor
$1.editor.setSelectedRange([0, 0])
Copy as HTML in Drafts
$1.editor.insertHTML(Daily Update …)

Points out that nothing has changed with them now WFH; they've always worked this way,
HQ is equivalent of a company intranet: docs, files, discussions, etc. Every one has access,
Teams are like departments or groups: distinct workspaces for the given team, admin gets to choose who sees what; unless you're added they're hidden,
Everything is "commentable": you can discuss things in context on every item,
DHH points out that they come back to these; sometimes two years later, giving the example of a an AB test,
Everything item exists under a URL; it's always referencable,
