Containment, besides being the architecture of our material world, is a fundamental organizing principle of life, language, and thought. This first essay reviews all kinds of containers, from the living cell to the physical and metaphorical containers we create. www.linkandth.ink/p/containers...
Containers All the Way Down
Containment pervades life, from life's own self-creation to the tools for storage and the tools for thought.

I have reviewed many #SHACL shape graphs over the last few years. There are some error patterns as well as exotic errors. And recently, I've noticed some very different patterns of LLM-generated errors. 🧵

Every piece of non-fiction makes three claims: main, supporting, and meta. Each is shaped by bias — self-serving, confirmation, appeal-to-authority.
But there are quieter ones too: the elegance bias and the God’s-eye-view bias.
And then there are the meta-claims…

In Canada, @gandersocial.bsky.social’s equity crowdfund is really resonating.

It turns out that people want Canadian owned and run social media.

Very excited to see this!
Exgoose me? You’re funding Gander how?

We're inviting Canadians to become co-owners.

Over 1.5k Canadians have invested from $255 to $10K or more, totalling $1.2M so far!

Become an owner! Tell friends, family, frenemies... anyone who wants better socials in Canada 🇨🇦

so @matteowong.bsky.social & I wrote on data centers: arguably the most important buildings in the world & are, in a way, holding the economy hostage. Byzantine financial instruments, private equity, depreciating tech, hype, $trillion valuations. it’s all there. an ai crash prob starts here.

After CSV, JSON, and XML, the 2nd part shows how the same containment principles allows to view HTML, XLSX, MS Word, and PowerPoint as #RDF knowledge graph. And also how to query REST API's with #SPARQL so that one query gets data from different sources.

A more polished version now.

(to my surprise, this is the second most read post on Link & Think, and since it gets so much attention, I gave it a bit more too)

Every time I bring up "zero-trust protocols" someone trots out this bit where they go "zero-trust systems are bad actually because society is built on trust and we want more trust not less" and the little voice in my head that goes "trust is expensive". We scale trust by doing more with less.

Now finishing the second part on Façade-X, which is the 5th essay in the Containment series, I remembered that my best attempt to explain #SPARQL for non-technical users also relied on containers:
