To me this is an example of extravagant and inefficient use of money. Instead, it should have been used to find a huge pool cavity somewhere high on one of the Hawaiian mountain or enlarge one. And then pump up the water to the pool when the electricity is cheap, and release/generate electricity when it is in demand. Stupid and robust implementation that just works and certainly less expensive than $219M.


I’m surprised that list doesn’t include a movie UFO. https://m.imdb.com/title/tt6290798/

Even though the plot is rather simplistic, it has a few interesting physical concepts embedded in a clever way.


That's pretty cool - reminds me about an experiment of improving small fridge efficiency by adding insulation on the sides of the fridge. In the end it worked out favourably for energy efficiency angle.

I'd be grateful if folks point out more improvements/builds that target off-grid home/office setups.


Great points...believe it or not it happens, but privately, in a case by case manner. Also why do you think companies and founders are in the business of making employees wealthy?! What is the specific reason for all of these being implemented?


Your trying to recruit people who can go work at a FANG and or have been burned by or have researched about startup equity shenanigans, so they have high requirements before they would even consider talking to you.


And where exactly these taxes will go? From pockets of CEOs to pockets of ... municipal bureaucrats, whose median salary floats at a humble mark of 175K/year?

If you spent time reading the article instead of leaving lies, maybe you'd know:

> The CEO tax is expected to generate between $60 million to $140 million per year. Haney said he wants most of the money directed towards health services.


Where exactly I “leave lies”? That’s a serious allegation and is thrown very casually here, as if it is self-obvious.

What he says and what will actually happen is two different things, especially in politics. If you have actually examined the URL I’ve posted, you might (maybe?) realize that money isn’t exactly the problem in the SF municipal budget. Maybe it is something else, like ehm.. actual governance?


This is a hilariously uninformed statement. Which cryptocurrency?

I'd even argue that the juggernaut BTC was _designed_ to be trackable, and as the recent history shows, law enforcement successfully and multiple times did exactly that when needed - tracked, identified and penalized bad actors.


I've got the invite to paypal's beta program for crypto. Honestly, you've got to be mad to be dealing with paypal. I've read anecdotes from people, losing access to their accounts, locked up money in paypal, etc... It all seemed to be just stories, seemed rare, circumstances unclear. Until one day this summer, out of the blue, paypal demanded ID of my spouse (for her account), and then after reviewing it, "permanently limited" the account, gloriously exclaiming:" Aha, we got your information, now you won't be able to use your current account nor open a new one!"

Trying to get to the customer support is yet another saga, and I will spare your time, but the net result is nil. Nobody in the support knows why the ban happened (there was no real reason to ban a paypal customer with over 8+ years, buying some random stuff on ebay), nobody can revert it, nobody really cares and there are no appeals.

Receiving a note from paypal today regarding crypto looked like a bad, really dumb joke to me and an insult for my spouse. You gotta be completely clueless or insane to trust this shitty company with your crypto. One of the key points for crypto is the lack of "deplatforming", which the sinister paypal does left and right, at the same time not even being able to explain its actions, nor comprehend consequences.

Paypal - never!


May I offer another tale:

• PayPal account holder for 14 years.

• Occasionally sell on eBay, and send/receive payments for freelancing work (maybe $10k a year)

• Semi-regularly buy and sell bitcoin for PayPal (about $1-2k a month)

• Never had eBay buyers claim DOA or anything suspicious, including high value sales (think GPUs, etc).

• As of a year ago, added to the “Funds Now” program which means my money will never be placed on hold, even during a dispute.

• The program worked as intended, as I was able to access my funds even during a dispute.

• For disputes I’ve had to make, they’ve always been resolved in my favour.

• Back when they had phone support pre-COVID, I always got local reps who knew what they’re doing.

On the other hand, last month my bank banned me and closed my accounts for depositing money into a local, regulated bitcoin exchange; with a letter giving me one day to sort out alternate banking agreements.

Go figure.


Look, believe it or not, I am in the same boat - never had issues with paypal, but neither I'm a heavy user. Randomness and the severity of paypal actions is a huge issue for me.

The subject of the discussion is paypal's surprise wedding with crypto. As stated in the above comment, my argument is: from customer perspective it is a bad, crazy proposition.

Hey, paypal has a loooong history of random, inexplicable deplatforming of customers, and mixing that corporate attribute with crypto makes sense only on executive powerpoint slides.


What is your country?


Could you cite an example where ECC requirement on GPU was real and demonstrated to be needed? In practice, I don't know anyone who'd willfully take 10-15% perf hit on GPUs, because of a cosmic ray.

The thermal design for "datacenter" card can be better for sure. And on-board memory size and design. That's about it. For how many x over geforce price tag is that?


"In practice, I don't know anyone who'd willfully take 10-15% perf hit on GPUs, because of a cosmic ray."

Virtually every server in data centers runs on ECC: the notion of not using it is simply absurd. And given that the Tesla V100 gets 900GB/s of memory bandwidth with ECC, versus 616GB/s of memory bandwidth on the 2080Ti without ECC, it's a strawman to begin with.

nvidia further states that there is zero performance penalty for ECC.

As to whether the requirement is "real", Google did an analysis where they found their ECC memory corrected a bit error every 14 to 40 hours per gigabit.

"That's about it."

Also ECC memory. Also dramatically higher double precision performance. Dramatically higher tensor performance. Aside from all of that...that's it.


It is very known thing. Whatever reasons were to create Glassdoor, but now in practice, it became an instrument of misdirection and is used to _deliberately_ and _intentionally_ mislead people.


The case for Mars by Robert Zubrin, Arthur Clarke - highly recommended for technically minded folks. One of my favorites of 2018.
