Question: can it discern (and label) different speakers? If so, could you kindly share the limit on speakers per video?

Right, if it’s a case interview, then higher accuracy ought to prompt the interviewee to ask: (1) Do the 200 cuts typically occur in clusters? (2) What’s the typical density, eg are they usually collocated? (as an alternative to the above) (3) Are there pathways that avoid the sea but connect Europe and North America (getting at density in the sea in question) Etc.

That’s what makes this one so good—lots of opportunities to extend or roll-back difficulty.

“Knowing that 200 undersea cables break every year globally, estimate the probability that 3 cables break in the baltic sea on the same day.”

I’m stealing this to use for grad-student mock-interviews—thank you!

They did, the translator communicates to the prisoners in English, and they pass along in Japanese to the guards. The article says they asked the translator.

How competative was the isp market in Utah before Google fiber subsidized the massive build-out?

Google threw in the towel on wiring more new cities about mid-way through the SLC build, which makes need think perhaps the biggest obstacle to your thesis bearing fruit, is upfront infrastructure investments…

Deepest condolences on your loss, and thank you for your candor—I can only speak for myself, but I’m definitely turning up my driving conservatism after reading your post.

The rc gliders are loaded chock-full with weight (tungsten or lead), we literally seek cover behind cars and boulders, and the bravest among us holds the radar speed gun—-if you want to see something outside of this world, or spark your kids’ imaginations as to the universe unlocked by the sciences—visit a DS site!

P.S. bring ski goggles—you’ll need them if the conditions are good, you won’t see without them if it’s a 400mph day—which is more and more common these days!

1) Clear your evening. 2) Do not Google, but rather jump straight to your favorite media platform, and locate a 2012 film named: “searching for sugar man.” 3) Watch alone because it’s impossible to watch without crying tears of joy

Who was calling customer service to begin with? I’m not a user, but I suspect there’s more margin with customers who are large enough to have a firm or internal team handle Shopify for them, and that’s not the type of person (one would hope) that would call customer service unless there was an account-level issue. If that’s the case, then they are simply evolving away from the mom-and-pop priority that made it so popular to begin with :(

Ha! I started on flight sim, made it to rc planes, and the first day of flight instruction, I told the instructor and he said: “if you can fly rc, you can fly full scale.” All I had to master was emergency procedures and some theory on the throttle vs pitch and I was off to the skies!

It’s usually a limited number of passes, so when customer k+1 requests access, customer 1 gets dropped. I don’t tell anyone about my library’s resources—they’re great, and so are the ones 2 counties up ;)

The rate at which your project becomes NPV positive.

If it takes $100 one year to return $110, then the irr is 10%, because a 10% interest rate would cause you to owe $10 at the end of the first year, which is exactly equal to cash generated.

Irr usually takes average accounting income per year in the denominator e.g. $10 in our case, and divided by the investment size.

Note: an investment that yields $5 at the end of each of two years is more attractive than one that pays $10 at the end of two years. Both have average accounting income of $5 per year, and the IRR is the same for each investment!!!!!! NPV scores the first incessant higher than the later--yet another reason why irr is a bad metric

Right. IRR has a number of problems, though many stem from the fact that it reports a percentage.

Npv/economic value added/etc. will yield one level per investment. And while you can sum these values for an aggregate, it’s not helpful to compare the npv of one investment for the other, because the fact that you have an NPV limits the risk of misinterpreting the investment as SCALEABLE. Some opportunities truly are finite, and cannot scale up—but if I were using irr to measure the value of selling my daughter painted Easter eggs, you’d think I have an investment of a lifetime—only to realize she has $35 stashed away, and is 10+ (hopefully 20+) years away from applying for credit!

Even were this not the case—short of an arrest, there is no way for the federal government to “serve you” in a contactable manner—whereas my sense is that this is not the case in Estonia and a growing number of spam nations, ie the government can mandate that citizens be reachable digitally (e.g. portal login is sufficient). The IRS has no inexpensive and scalable way of proving that the person on my end of the Internet is the person with the SSN in the filling (login.gov is great but not pushed throughout all the service branches).
