Мою старую лингвистическую задачку использовали в Первой традиционной израильской олимпиады по лингвистике:
https://israel-ling.org/olimpiada
(Кстати, название "Первая традиционная" само по себе продолжает традицию "Первой традиционной московской олимпиады по языковедению и математике").

Обнаружил легкое побочное решение, которое не пришло мне в голову много лет назад. Да и саму задачу, видимо, можно было сделать элегантнее.

Так бывает. "Рибосома как депо цинка" (repression by zinc was predicted for genes encoding a variety of paralogs of ribosomal proteins. The original copies of all these proteins contain zinc-ribbon motifs and thus likely bind zinc, whereas these motifs are destroyed in zinc-regulated paralogs. We suggest that the induction of these paralogs in conditions of zinc starvation leads to their incorporation in a fraction of ribosomes instead of the original ribosomal proteins; the latter are then degraded with subsequent release of some zinc for the utilization by other proteins. Thus we predict a mechanism for maintaining zinc availability for essential enzymes, https://www.pnas.org/doi/10.1073/pnas.1733691100) было красивой, но слишком сложной идеей; в большинстве случаев все сводится к замене более эффективных цинк-зависимых белков на, видимо, менее эффективные цинк-независимые в условиях цинкового голодания. Впрочем, в некоторых случаях потом люди видели, что цинк действительно высвобождается для других белков ("Liberation of Zinc-Containing L31 (RpmE) from Ribosomes by Its Paralogous Gene Product, YtiA, in Bacillus subtilis" https://journals.asm.org/doi/10.1128/jb.188.7.2715-2720.2006).

For tech stocks, “the main thing is yields,” Essaye said. On Telegram’s website, it says that Pavel Durov “supports Telegram financially and ideologically while Nikolai (Duvov)’s input is technological.” Currently, the Telegram team is based in Dubai, having moved around from Berlin, London and Singapore after departing Russia. Meanwhile, the company which owns Telegram is registered in the British Virgin Islands. At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. But the Ukraine Crisis Media Center's Tsekhanovska points out that communications are often down in zones most affected by the war, making this sort of cross-referencing a luxury many cannot afford.
