  1. Will it work for Lithium or Gold? on New Material Can Soak Up Uranium From Seawater (acs.org) · · Score: 1

    Lithium is extremely abundant in the sea water. It occurs at about 200 ppb in the ocean. The current sources of Lithium are salt flats and brine puddles in salt flats. So I wondered if a similar polymer can be developed using similar computational methods to extract other valuable metals like Lithium or Gold. Li is the lightest metal and U is the heaviest. So it might not be so easy for Li. Gold it could happen, but probably Gold is not as viable. If a gold extraction polymer is developed, the gold price will crash, and the invention will become worthless.

    It is not 50% of the total value of the currency. It is the 50% of the computing power that verifies correctness. Once you have 51% of the votes to verify it, you own ALL the value in that currency.

    Everyone knew about 50% verification vote issue. Once state actors get into the game private people stand no chance against this. That is why when it was very comical to read about crypto currency reigning supreme over state issued fiat currencies.

    The Good News: It is possible to create a news delivery platform that is not funded by advertisement. It is not funded by relentless pursuit of clicks and eyeballs. It will not be a race to the bottom. Millions of people chipping in a few bucks, voting with their dollars for trust worthy news will bring the much needed price signal to the news delivery platform.

    Bad news: It is Netflix.

    The only place ICEV is still holding on is in price below 40K, refueling speed. The BEV prices are falling inexorably. In three years, it will be at 30K. Refueling speed will become a non-issue. People will adapt to 30 minute breaks every 250 miles.

  8. Re:Paper money is not going away on Elon Musk: Bitcoin Structure is Brilliant, But Has Its Cons; Paper Money is Going Away (ark-invest.com) · · Score: 1
    There is strong incentive for the government to cut down on paper money. Cheaper, can track people, no worry about counterfeits. So you can expect the government to make it more difficult to use paper money.

    Visa and Mastercard would love the idea of collecting 2% toll on every transaction. There are lots of enemies for paper money.

    They might succeed.

    Normally that is how I would respond. But in this case there are some mitigating circumstances. Elon was involved with Paypal, some sort of payment tracking system. And it is mentioned to be off-topic. So I am going to be a little forgiving here.

  11. I give simple coding problems. on Programming Interview Questions Are Too Hard and Too Short (triplebyte.com) · · Score: 1
    I dont give them coding problems to be solved on a computer. I give them a relatively simple problem. Filter out odd numbers from a vector of integers. Of find a path from the given sets of pairs of connected cities. Pseudo code on paper.

    I check to see if they spend enough time to understand the problem, do they ask questions to make sure the specs are, I like it if they ask, "do you want a fast algo or minimum memory algo?". I ask them think out aloud, and guide them towards the solution. Then the fun starts, I change the spec, I ask them to reimplement it optimizing for speed instead of memory or vice versa. Change it from "filter out odd numbers" to "filter out numbers divisible by another set of numbers", etc etc.

    Right at the beginning I tell them, the test is not on programming. The test is on "Am I able to communicate well with you, and are you able to communicate back with me?"

    I hire only PhDs and Masters from US universities, coding is necessary but not sufficient for my positions.

    So, yes, there are hiring managers who would happily go through the same hiring process themselves.

    All Buddhist monastery lamas must be state approved. It has disrupted the centuries old tradition of Panchan lama finding the reincarnation of the Dalai lama and Dalai lama finding the reincarnation of Panchan lama. The current Dalai lama is in exile. Old Panchan lama is dead, replaced by government approved lama. They did not permit current Dalai lamas emissaries into China looking for the reincarnate. So Chinese government will identify the next Dalai lama once the current one dies.

    Now, internet? Why would anyone think China will accept an international control of the internet?

    Wasted click bait opportunity. Could have snagged a bunch of TSLA and TSLAQ clicks with a little bit of creativity in the head line by including Elon.

    The short haul market has been eviscerated by TSA. It is almost like an auto-immune disease. Terrorists caused a flea bite of a damage. And the over reaction by the public, the politicians and the media resulted in this huge organized mass gate-rape, adding two hours to all flights. It is simply not worth flying less than 400 miles.

    On the long haul, Europe keeps making wrong bets on fuel prices. Arab oil shock killed Concorde. A380 cost estimates was based on cheaper aviation fuel deliverable in the middle east, and range needed fly to anywhere in the world after a cheap fillup. The advantage is half the differential between fuel price in the middle east and the price at major airports. Boeing with its longer range smaller plane nullified the advantage without incurring the disadvantages of the huge size.

  16. Re:Reuse before recycling on Electric Car Batteries Might Be Worth Recycling, But Bus Batteries Aren't Yet (arstechnica.com) · · Score: 3, Interesting
    The battery pack may not be reused as is without the knowledge of firmware, wiring harness etc. But the pack can be disassembled into cells and repacked into a new pack, after discarding cells falling below performance threshold.

    The original article is looking in terms of carbon emissions involved in recovering original raw materials. Iron is cheap and plentiful and so its not worth smelting the pouches. Or so it claims. I know steel mills buy huge quantities of scrap iron and melt them along with ore. I assume it would be cheaper to melt the cells than to dig ore out of deep mines.

  17. Geography of India on How India's Single Time Zone Is Hurting Its People (bbc.com) · · Score: 5, Insightful
    The IST is based on the longitude passing through Allahabad and Chennai, right in the middle of its east-west spread. It is smack dab in the middle of Ganges plain in the north. The entire fertile plains of the rivers Godavari, Mahanadhi, Krishna and Cauvery are centered around that meridian.

    The portion exposed to later sunsets, by 30 minutes are the states of Rajastan and the kutch of Gujarat. The most arid, dry parts of India that includes the Thar desert. At the border is Pakistan, in a different time zone giving children across the border better sleep time.

    One would think compare the achievements of children across the border of India and Pakistan to see the effect of time zone, while keeping remaining geographical influences the same. Instead the researcher compares the densely populated fertile parts of India with the desert part of India and tries to attribute the differences to the time zone.

    It is a thesis from Cornell. I read only the abstract and the intro. I did not see any indication the researcher is controlling for this. Hope there is a good explanation for it.

    Most of the enforcement of contracts is based on the assumption of informed consent. There are laws that protect people who lost the ability to reason due to senescence, and those who never had it to begin with from being lulled into contracts they dont understand.

    So if a person is able to prove that they are incapable of understanding the contract they have signed, they should be able to plead for relief.

    But the issue is not that. These cases never go to court. All they need is a fig leaf to pretend what they are doing is legal, and sell the data, make the money and run away. Even if one person manages to drag the company to the courts, and gets legal relief, the damage is done, miscreants and profiteers have bolted ages ago.
