нашел ошибку в интернете

В онлайновом вебстере написана херня на тему алгоритма кода Грея. Казалось бы, чего там мудрить-то? Ну типа таки ошиблись. День потерял, пытаясь найти ошибку у себя. Стыдно даже. Мораль: думать надо головой, а не интернетом.

and now on "legalize" problem

You know what? I think we should start with legalizing tobacco. Is it legalized? Does not look like it. And I believe as soon as the percentage of tobacco smokers drops below 10%, it will be totally banned. Democracy, my ass. Combines perfectly with fascism.

So, I remember Stevey Yegge was blogging how hard it is to legalize marijuana, due to all the infrastructure and permits and legal dosage, etc. Try this with tobacco, you'll be amazed how hard it is to legalize tobacco. But it is legal. Meaning, just don't ban, and regulate only the necessary stuff. Nobody's supposed to smoke in a kindergarten anyway.
