PLACEHOLDER — nobody wants a second proprietary language

Thu, 06 Aug 2026 00:00:00 +0000

Placeholder for the THOUGHT view, which is the same shape with a lighter template.

This is placeholder content. A thought is shorter than an essay and carries no version, so it renders without a citation block.

The argument, when it is written, is that every vendor solving the portability problem by inventing a new language is solving their problem rather than yours.

PLACEHOLDER — the semantic layer needs an Esperanto

Wed, 05 Aug 2026 00:00:00 +0000

Placeholder text so the essay view has something to render. Replace before the epoch.

This is placeholder content. It exists so the essay template, the citation block, the revisions sheet and the “also published” list all have something to render before the real writing lands.

What this page is proving

That an item file originating here produces a page at its slug, carries a version and therefore a citation block, and appears in the feed at full text.

Every vendor now ships a semantic layer. Strip the marketing away and most of them mean a YAML file with a naming convention. The interesting question is not whether the layer exists but whether two of them can agree on what a measure is, and so far the answer is that they cannot, because nobody has written the grammar down.

Why the length matters here

The reading time on the page above is computed, not typed, so this section exists mainly to make that number something other than one minute. Replace all of it.

PLACEHOLDER — on the industry's fondness for the word semantic

Sat, 01 Aug 2026 00:00:00 +0000

Ran on both networks; the words are archived here so the row is the whole item.

Every product page now has a semantic layer. Almost none of them will tell you what the word means in their case, which is usually a sign that it means “a YAML file”.

This is placeholder text standing in for a real archived post. It renders inside the row, expanded in place by a native <details> element, and generates no page of its own.

Dynamic formatting by hierarchy level with ISINSCOPE and ISATLEVEL

Mon, 13 Jul 2026 00:00:00 +0000

The question that comes up every time someone puts a hierarchy in a matrix.

PLACEHOLDER — why your DAX is slow: the four usual causes

Thu, 02 Jul 2026 00:00:00 +0000

Placeholder row so the VIDEO form and its duration column are exercised.

PLACEHOLDER — what a benchmark for DAX would have to prove

Thu, 18 Jun 2026 00:00:00 +0000

Placeholder past talk, here so the archive table on /speaking/ is not empty.
