Hacking for years. Fond of creative combinations of existing things to make solutions.

I am surprised no one spotted the obvious solution:
perl -e '$_=24;print+(y///c,$m=$_)&&$_*3/4 .$/'

Wonderful. I don’t particularly care if it is or is not a valid test. I like the “wrong” renderings better. Some are hilarious, some … inspired.

Of late I have grown fond of ... brace yourself ... RDF in turtle format for config files. Supports comments, multiline literals, built-in support for references, and rich typing via xsd casting when necessary e.g.
ex:subject ex:createdOn "2002-01-24T12:00:00.000Z"^^xsd:dateTime ;
You can have no namespace (:subject :name "foo") or one or more to help separate metadata and structure (the config structure) from actual config data (ex:myInstance config:logfile "pathname to file"). And of course, all the metadata itself is labelable and can carry comments and descriptions so the config is essentially self-documenting. Or at least there is a standard, straightforward way to extract and organize the labels and comments if time has been taken to add them.

UGN -- unusable game notation. That has a ring to it.
UGN was designed with SPARK and AWS S3 pbzip2-aware threading JSON readers in mind. For an analysis of a year's worth of lichess games -- over a billion, maybe more -- I believe UGN is a good solution. Try bucketing clock time vs. blunders or castling analysis or opening vs. ELO on 1 billion PGNs. Not simple search; aggregation. In the end, UGN is an information architecture; JSON is used as a convenient implementation/representation but it happens work well with SPARK and S3. And you can reliably use jq or even grep on the same UGN files. I didn't feel the need to create yet another binary format.
Anyhoo.... We're up to 60 downloads!

:-) You visited the site so props for that. But I find it odd you call the soup of braces, colons, and quotes a complete mess. That's JSON. As in industry standard everyone-uses-it JSON. If you're not familiar with the space I can see why PGN has more human readable appeal.

Well... it's actually more parseable. Human readability is not the primary goal of BGN. It's precise capture of information esp. things ending up in PGN comments like %eval and %clk

Agreed. Multi-multi billion. It is a fundamental change in the global energy dynamic -- including the fact that D-T reactors are still use heat exchange which means heat is also a useful output product for industrial purposes. MSRs are really good for this but of course are fission not fusion reactors.
It borders on a national security issue.

Very good.

Exactly; see pollinators comment above. Although as tech progresses... perhaps we can make black plants as attractive to genetically modified pollinators. Do I sense a slippery slope here?

A fascinating piece that combines technology, precision in micromanufacturing, design aesthetics, economics, politics, and history -- centered on the now all-too-forgettable wristwatch in the smartphone age. I haven't worn a wristwatch since I got a Blackberry about a 100 years ago (wink) but it is articles like this that rekindle my appreciation of them.

Adding to the chorus of woes, my legal first name is Paul and middle starts with A and often the ticket comes out as "Paula". I have had at least two heated encounters with gate attendants saying the ticket could not possibly be mine because I don't look like a "Paula".

Agreed! Unexpected and made my morning.

It does; I got this running easily because fortunately I have current postgres and psycopg2 installed so no tangential problems to interfere with the main event.
So clearly the example shows how I can issue a SELECT statement against the raw data. Is there a concise statement about what the DP'd statement offers me? This isn't access control or raw data obfuscation in the traditional sense. What is the consumable use case here as opposed to, say, the statistically private use?

Is there a "hello world" example available that is a highly simplified version of https://qrlew.readthedocs.io/en/latest/tutorials/getting_sta... ? Just 2 tables, 2 fields apiece, with the join bringing private data into the mix?
