Stravinsky allegedly said something like:
If you tell me I can compose anything I want I don't know where to start, but if you tell me it must be for tuba, triangle, and bass drum, and must last for 5 minutes I can begin composing immediately.

In other words, at least in the arts, constraints - as long as they are not too restricting - can be very helpful.

http://faculty.webster.edu/cor... "YOUR FLAW" by Viennese writer, poet, and actor Karl Kraus, translated from the original German:

That flaw of yours, that vent - I love it, dear;
it’s part of you
and ranks with me among your finest features.
When I find out that others have it too,
I look for it and almost see you near
and love all similarly wanting creatures.

If I, for want of you, that want should miss - were we to part –
where would I better find my consolation.
than in that flaw I love with all my heart?
And when you're gone, with such a want as this
the homeliest would win my admiration.

Yet if there came the fairest of the fair,
and flawless she,
my thoughts of you would linger and keep haunting.
No matter what her charms and virtues be,
her fault would be the flaw that wasn't there –
I would not want her if your want were wanting.

None, except that on the UK stock market (at least) it used to be a thing - and apparently still might be - that a sufficient number of investors thought that a smaller price per share was a *good thing* that companies used to split their shares to reduce the price per share, allegedly to increase their liquidity. From my point of view the only practical effect of this was to make it more complicated to calculate the capital gain for tax purposes in the three months I spent working on a special project for an insurance company's accounts, but as I'm neither an investor nor an accountant, just someone with a mathematics degree, what do I know? https://www.informdirect.co.uk/shares/share-split-and-subdivision-explained/

Yes. I was wondering what on earth is the point of having US Space Force personnel actually in space, as opposed to on or under the ground, other than staging re-enactments of scenes from Starship Troopers and Star Wars, but presumably not from Star Trek?

Submission + - Researchers Can Duplicate Keys from the Sounds They Make in Locks (kottke.org)

colinwb writes: While https://en.m.wikipedia.org/wik...">you cannot hear the shape of a drum it seems you can hear the shape of one type of key from the sound it makes in the lock. That says it all really, but from the article:

Once they have a key-insertion audio file, SpiKeyâ(TM)s inference software gets to work filtering the signal to reveal the strong, metallic clicks as key ridges hit the lockâ(TM)s pins [and you can hear those filtered clicks online here]. These clicks are vital to the inference analysis: the time between them allows the SpiKey software to compute the keyâ(TM)s inter-ridge distances and what locksmiths call the âoebitting depthâ of those ridges: basically, how deeply they cut into the key shaft, or where they plateau out. If a key is inserted at a nonconstant speed, the analysis can be ruined, but the software can compensate for small speed variations.

The result of all this is that SpiKey software outputs the three most likely key designs that will fit the lock used in the audio file, reducing the potential search space from 330,000 keys to just three. âoeGiven that the profile of the key is publicly available for commonly used [pin-tumbler lock] keys, we can 3D-print the keys for the inferred bitting codes, one of which will unlock the door,â says Ramesh.

For an economy that is "crap" France seems to be doing not bad: per capita GDP is about 75% of the USA (which I suggest is quite a lot better than you'd get in a truly "crap" economy), and in a list of the per capita GDP of 229 countries France comes in at 41, not hugely behind the USA at 19.

Submission + - How a Half-Inch Beetle Finds Fires 80 Miles Away (scientificamerican.com)

bodog writes: How does a Half-Inch Beetle Find Fires 80 Miles Away? Why, its called Stochastic Resonance of course! (also, one hell of a sensor load-out..)

  " In this scenario, added thermal noise counterintuitively helps a sensor pick up a signal.
A signal below the threshold for triggering a sensor – but still close to it – will resonate by chance with a portion of thermal noise that is the same frequency. When there is more noise, there is more signal at that resonant frequency. Together, noise plus signal adds up to an impulse sufficient enough to trip the sensor when signal alone or signal with less noise would not. Incredibly, the measurement gets more precise in the presence of noise than without."

Submission + - A tectonic plate may have peeled apart—and that could shrink the Atlantic (nationalgeographic.com)

pgmrdlm writes: For years, João Duarte has puzzled over a seemingly boring underwater expanse off the coast of Portugal. In 1969, this site spawned a massive earthquake that rattled the shore and sparked a tsunami. But you would never know why just from looking at the broad, featureless surface of the seabed. Duarte, a marine geologist from the Instituto Dom Luiz at the University of Lisbon, wanted to find out what was going on.

Now, 50 years after the event, he may finally have an answer: The bottom of the tectonic plate off Portugal's coast seems to be peeling away from its top. This action may be providing the necessary spark for one plate to start grinding beneath another in what's known as a subduction zone, according to computer simulations Duarte presented in April at the European Geosciences Union meeting.

If confirmed, the new work would be the first time an oceanic plate has been caught in the act of peeling—and it may mark one of the earliest stages of the Atlantic Ocean shrinking, sending Europe inching toward Canada as predicted by some models of tectonic activity.

Why do people apparently think that Magna Carta has any relevance to those of us - the large majority - who aren't barons or clergy?

Magna Carta - Wikipedia:

... First drafted by the Archbishop of Canterbury to make peace between the unpopular King and a group of rebel barons, it promised the protection of church rights, protection for the barons from illegal imprisonment, access to swift justice, and limitations on feudal payments to the Crown, to be implemented through a council of 25 barons.

... The political myth of Magna Carta and its protection of ancient personal liberties persisted after the Glorious Revolution of 1688 until well into the 19th century. It influenced the early American colonists in the Thirteen Colonies and the formation of the American Constitution in 1787, which became the supreme law of the land in the new republic of the United States. Research by Victorian historians showed that the original 1215 charter had concerned the medieval relationship between the monarch and the barons, rather than the rights of ordinary people, but the charter remained a powerful, iconic document, even after almost all of its content was repealed from the statute books in the 19th and 20th centuries. Magna Carta still forms an important symbol of liberty today, often cited by politicians and campaigners, and is held in great respect by the British and American legal communities, Lord Denning describing it as "the greatest constitutional document of all times – the foundation of the freedom of the individual against the arbitrary authority of the despot"....
