Yes, it's quite clever. An equivalent proof is dividing 0.999... by 9 using long division, which comes out to 0.111... which is equal to 1/9. Now use fraction notation and it simplifies to 9/9 = 1. Not quite as robust as the limit-based proofs but it's a quick answer and gets to the heart of the issue of repeating notation not capturing the whole picture.
> How can the US have that little protection of their workers..?
The US has spent the last 65 years chipping away at unionization rates and other pro-employee protections. The overall rate of unionization in the US peaked in 1954 [1].
Yes - this is a major function of private equity in general. They even have investment banks and firms that specialize in "buy side" versus "sell side" of the transaction.
I once had a consulting gig where the customer desperately wanted to build a Spark/Scala ML pipeline, for a dataset that was 10 MB. We spent 3 months hammering it together for a flat Python process that would've taken us 2 weeks.
> This find xargs mawk pipeline gets us down to a runtime of about 12 seconds, or about 270MB/sec, which is around 235 times faster than the Hadoop implementation.
Long-haul trucking would be a great use-case. Even if you need humans for local pilot guidance, you can queue them up to a "cell phone lot" and courier the last-mile drivers in between shifts of going back & forth. It would also mean drivers would be based more locally to points of loading, rather than having to be constantly on the road away from home.

Which would probably make it much easier to hire drivers, too. Lately, long-haul trucking has had a hard time recruiting people into the profession, because the pay isn't that great and the lifestyle completely destroys any relationship you have. Local trucking doesn't have this problem: a driver can drive for the day and be home for dinner.
Long-haul is more than just driving. Will smart trucks be able to put chains on and pull them off when necessary? Handle unloading of items of weighing process proves problematic? Call for pick up of items removed during weighing? Handle snow? Handle loss of sensors? Handle run away down hill on a steep incline. None of these are insurmountable, but all are well out of the current horizon. Heck, just refueling is hard.
Most of those can be solved by changes to the truck or delivering spot local drivers. For weighing the trucks could run different trailers with load cells to weigh itself to ensure they're under the weight limit for their route. For snow there are automatic chain systems used on buses today those might be adaptable. Run away ramps are usually marked so a combination of good mapping data for route planning and finding run offs and vision/driving they'll have anyways.
Cash or a bank demand account is not without their own inherent risks. A fire, robbery, or forced currency exchange could destroy the value of the physical commodity of cash, and the FDIC only insures individual account bank deposits up to a certain limit so a bank institution failure could cause losses to individual accounts.
Ok you're arguing that there is no such thing as a liquid store of value that that offers a better return than a negative yield government bond?
So let's say I'm a bank with a stack of 1B in high denomination central bank notes. I calculate the rate of return as zero minus the annual cost of securing those and the annual risk that they are stolen or destroyed. Inflation isn't a factor because the bond is in the same currency. Based on your explanation that rate of return will be lower than the -0.11% that I would get from a german 30 year bond today. And there's simply nothing I can exchange those central bank notes for that would do any better than the bond.
Like OP I've never understood negative yield debt and I'm trying really hard to.
Drinking multiple _liters_ of water in a relatively short time can cause water intoxication [1] due to the drop in relative electrolyte levels. I got it once at scout camp where, unfortunately, the medic misdiagnosed me with dehydration and had me drink a gallon of water. I ended up urinating about every ten minutes for the next 24 hours, and is one of the most unpleasant experiences I've gone through.
Most MLM's tout a flexible working schedule which women tend to prefer due to being saddled with a higher average proportion of the child-rearing and elder-care responsibilities.
Over time the attrition rate for attention increases. As a result it becomes harder to justify further investments in usability features or content quality because you can no longer leverage the increased attention of more users in the future. This can lead towards a death spiral of lower frequency updates leading to less viewers leading to less updates.
For a venture-backed site even hitting a 20% growth rate per month would be a warning that you're not growing fast enough to justify continued investment, as was the case for a recent postmortem on Gumroad [1].
Given that this post was from 10 years ago that's definitely not the case for Hacker News, but in this climate it's gotten even more extreme if you're relying on venture backing.
It's not needed to sustain the business but it is needed for those who invested in it and would like to cash out on a higher valuation - which typically is achieved through growth.
