Funny how now matter where they start out, just about everybody who attempts to take on the 3x+1 problem eventually ends up in pretty much the same place:
On the subject of "slightly" shady, let's not forget Barclay's enabling (via a questionable naming rights deal) of neighborhood-killing, taxpayer-fleecing eminent domain abuse, either:
But the phrase so muß auch sometimes is used in causal contexts; for example:
Sind zwei Zahlen gegen irgendeine Zahl prim, so muss auch ihr Produkt gegen dieselbe prim sein.[1]
Or if you're into Amtdeutsch:
Sind mindestens zehn Mitarbeiter mit der automatisierten Verarbeitung personenbezogener Daten nicht nur gelegentlich beschäftigt, so muss auch ein bDSB bestellt werden.[2]
Still not quite like the way "so" is used in English, of course.
For senior positions, I will ask a question early in the 5 minutes that is a complete tangent and has little to do with their goal. A star candidate will politely refuse to go down this rat hole and insist that we stay on topic. This seems unfair since an they’re in an interview and just doing what they’re being asked.
Got that right. Trick questions are always unfair (and mildly insulting, and just a plain waste of time) in interviews, just like they are in real life.
"Star interviewers", on the other hand, know that there's no reason to ask candidates to jump through artificial hoops like these.
OK, let me qualify: Vinyl (when played on commodity equipment) does, almost unavoidably, suffer mild (or worse) analog degradation. This is why (if you're of a certain age) you'll recall that for high-value purchases, we usually made cold replicas (uh, "tapes") to insure that the "master" got played as infrequently as possible.
CDs, however, not only degrade spontaneously (even when stored "properly"), but the degradation is pretty much "either-or" -- when they do degrade, usually the whole thing is pretty much unplayable (unless you're putting it in a very expensive player).
In any case, from my own extensive experience over the years, item for item, I've had quite a few vinyl records suffer "moderate" deterioration (aftr heavy playing), but virtually all were still playable to some degree. Really - unless you leave them in the back of your car for too long, that's usually the worst that happens.
Meanwhile, an annoyingly high % if CDs simply get scuffed, or are left out in the air too long -- and end up irreparably damaged and unplayable (at least on generic players).
The fact of the matter is, the hypothesis that "whiteboard skills == mondo real life developer skillz" is pretty much an unspoken, and utterly unquestioned article of faith out in vast stretches of startupland.
Well the trick is not to "memorize" the rational approximation, but to derive it (or rather, the CF approximation to it) directly from first principles, i.e. using the analytic properties of pi itself.
