Actually, for the company that I worked at, and the level of folks we hired, I often heard about how they went.

The only one that made me sad, was a chap who used to show up on the Adobe Photoshop splash page. We offered, he declined.

In the aggregate, I think things turned out OK for all of us. There are some folks that I have to admit, probably did best by not accepting us.
Possible solution?: blow air through pipes in the ground to make the sand fluid.
This reminds me of century eggs, which are also preserved in mud that makes an airtight seal. That takes care of everything except fermentation of the fruit itself, and for century eggs I think they use ash/lime:

Sausages are also cured by killing the the bacteria inside with salts and smoking, and then putting them into a casing (the intestines) that defends against air from outside.
Yeah but in this case, the hydropower is being used for power generation, not as a battery supplement for solar/wind, right? Does it need to be so massive to act as a replacement/alternative for Lithium battery banks?
Netflix doesn’t act unethically. They are upfront about how they hire and fire and people select into applying there and jobs there based on that. Same as CostCo has much higher standards for employees than Walmart and much higher benefits. If all employers were like Costco lots of people would be unemployed who currently have jobs. Having an employment model that is not perfectly average is not unethical.

John Bardeen is one of the greatest physicists of all time. He is the only person to win two Nobel Prizes in physics.

Shockley may have been a talented scientist, but he did not invent the transistor, and tried to steal (not share in, but steal) the credit from the people who did.

Newton was a jerk, but he invented modern physics. Shockley was also a jerk, but that doesn't mean he invented the transistor.
This technique isn't actually speeding up the NeRF rendering algorithm.

It bakes the NeRF back to a semi-discrete representation (Octree of Spherical Harmonics voxels) which can render near-identical results at interactive speeds.

The baked data is much larger than the original NeRF model (2gb vs 5mb), but they can be downsampled to 30-100mb with little loss in quality.

Why would we use lithium ion batteries?

I would imagine the approach to store the energy would be to use the energy from solar panels to do work that can be used to produce electricity later.

For example, you could use solar energy to pump water back uphill to flow down through a hydro electric dam later.

Even if it isn't the most efficient, in the long run it would likely provide the best scalability and least long term environmental impact. Once you have the facility in place, the same water could be pumped uphill to flow back down a million times over with the only overhead replacing water lost through evaporation and maintaining the facility.

Am I missing something that makes such an approach unfeasible?

Hosting a personal blog on old / cheap hardware at home and accepting some downtime now and then should be a trade-of worth making for most. An interconnected web of documents served from personal computers residing under a desk or in a basement – it is a beautiful thing.

We nerds often seem to fall into the trap of over-engineering things, like, spending a lot of time building personal stuff that can scale into the infinity – only to end up never having more than 10 concurrent visitors at any given time.

By accepting and embracing the intermittent and slightly unstable nature of serving websites from our homes, we can take back much of the in(ter)dependence and hacky, quirky fun that many of us fondly remember from the 90's and 2000's.

Setting up a webserver on a Pi and serving it from home can be a fun project, not necessarily trivial for everyone, but definitely within reach for most technically inclined people.

Might be among the cheapest, easiest AND fun ways to host a static site :)
I would think that's more of a cognitive thing where if you don't normally spend time around people with Down's syndrome, the particular physical features that characterize Down's syndrome really stand out in a way that makes you perceive them as looking less distinctive as individuals. But once you get used to it, it becomes apparent that they look as different from one another as anyone else does.
It's one thing to produce insulation, or bio-bricks from kiln dried mycelium, but to leave the mushroom mycelium alive seems like a hazard to both the occupants and surrounding building materials. Not only will the mushrooms release spores which can get into peoples lungs, clothing, furniture, etc. and then start consuming those materials, but the mycelium itself will continue to spread into any organic matter that it is in contact with.
Tell HN: Crypto Wallets Trust Wallet and Ledger appear to be compromised
I'm really devastated. My nephew just called me and told me all his cryptocurrency is gone -- valued over $40,000. He has spent years earning it and resisting pulling it out, hoping he could eventually use it to pay for his college education.

Here are the facts:

- He has a Ledger Nano S wallet.

- That wallet had 4.77 LTC, 4.48 ETH, and 0.73 BTC.

- The Ledger generated a passphrase containing 24 words. He didn't add the 25th optional word.

- He recorded that passphrase on a piece of paper and hid it.

- No one had or has access to that paper. This is an absolute certainty.

- That passphrase (those words) were NEVER entered anywhere.

- On February 24th at 5:45 AM Eastern Time, the BTC was stolen.

- On the same day, at 6:46 AM and 6:48 AM, the ETH and LTC, respectively, were stolen.

- He also has a Trust Wallet.

- He had $1500 worth of NPXS and $1000 worth of TRX in that wallet.

- On February 24th at 6:48 AM and 6:55 AM both of those were stolen.

- The passphrase for the Trust Wallet is saved as a screenshot on his iPhone.

- His iPhone has not left his possession.

- His iPhone has a 6-digit passcode.

I have the recipient addresses. It looks like the thief has stolen crypto from others as well.

Note: Both wallets were hacked on the same day at around the same time. Both had separate passphrases.

Can someone please shed some light on what can be done, if anything? How were both wallets compromised at the same time?! If nothing can be done to retrieve the crytpo, what can be done to prevent this from happening in the future.

Edited to add:

Here's the BTC transaction:

> The brilliance of her product is basically marketing. I was glad when my sister said, “I am eating to many of her frozen dinners. I’m beginning to think they are not good for me?”

My food philosophy is simple: I use the most basic ingredients as is practical, buy the freshest stuff I can, and cook nearly everything at home.

I can be pretty confident about what's in my food, because odds are I put it there. We save a ton of money on eating out, and I think it builds better friendships when you can invite people over for a meal you cooked.

This comes at a time cost, but with practice, you get to the point where you can cook amazing food pretty quickly. Not as fast as an instant meal, but it'll taste ten times better, and cost a quarter as much.

Also, I've found I don't really like most processed food anymore after eating like this. Some stuff is okay -- potato chips are way easier to buy off-the-shelf -- but I honestly start to feel sick if I eat McDonalds, or drink a Coke, and I pretty much grew up on both of those.

I know this isn't accessible to everybody -- if you're working two jobs and on the weekends, there's no way you've got time to cook -- but if you have the time, I'd say it's worth it.

I really liked Henry Huggins. It was easier to relate to him than to a girl, though I enjoyed Ramona Quimby stories too. I think it was a story about Henry and night crawlers that got me thinking about how to start my own business. I failed (I lived on a farm in a sparsely populated part of the world) but I spent days, maybe weeks, trying to come up with ways to make money.
But hydrodynamics experiments actual give correct answers, because physics empirically matches physical theory, but economics doesn't.
One would not use batteries for the "rare, but prolonged" storage use case. You'd want something with lower capital cost, even if it were much less efficient. For example: hydrogen burned in turbines.

Deep expertise is absolutely crucial to properly scope projects, get the right requirements from stakeholders, understand level of effort and understand dependency trees.

Ach! I forgot you don't have electric kettles in the US because of some crappy power supply issues! When making any kind of pasta, I boil the water in a kettle first, then pour it into a pan on the hob (aka stove) - so pasta starts cooking in 3m or so.

Anyway, without a kettle I guess it's still doable around the 20m mark, as long as you have a gas or induction hob, and while the pasta is cooking you grate the cheese and make the sauce.

And on the sauce, I make a roux, add full-fat milk, add the cheese and season - easy. If you want to get fancy, chopped onions and chunks of pre-cooked (or tinned) ham mixes things up.

"Almost all heat on Earth is solar in origin, including the majority that we don’t use."

yes and it's spread out thinly which is why it doesn't kill us.Your solution is to take the least energy dense form and spend material, huge areas of land and money to build a solution that is inferior to all the other solutions.

Scales up to Kardashev III"
In theory not in practice. You are speculating not actually proving anything.

"Only looks like lots of land because there’s 7 billion people."

Ehh we are going to be 9 billion. Not sure what exactly you think it proves. You are playing excel sheet scientist not actually proving the application in reality.

"No more complex than anything else in the modern world, therefore calling it complex as a criticism is false."

There is a world of difference between having a nuclear power plant or using oil or gas or coal which all have the energy STORED in themselves vs having to convert thin layers of energy into batteries which again aren't even close to be able to deliver the kind of utility the other sources can.

"Can be forecast reliably a week ahead in great detail"

No it can't and it isn't and will require backup from other sources. Again excel sheet acrobatics isn't really useful here.

"Less than the alternatives, again only looks big because there’s 7 billion people."

We are going to be 9. It's a reality and you aren't actually dealing with it. It's not going to go away.

Batterie are not demonstrated as being a solution by any metric what so ever so no.

You keep comping up with speculative solutions which wont actually work nor solve anything as the grid will never be flexible enough and batteries can't actually deliver what you seem to be dreaming they can.

"Literally Dyson swarms."

Again more speculcation.

Come back when energy from wind and solar is more than 10% of the worlds energy consumption.

"“PV + battery” is two items, calling that a Rube Goldberg machine is like dismissing the wheel because you get the most out of it by adding an axel."

I am not. I am calling all your other solutions to solve the issues with intermittency like grids and weather forcasting PLUS batteries plus storing of energy in batteries and PV for rube goldberg machines.

I tried a trie with data that I thought would work perfectly with it. There were a good amount of shared prefixes. But it ended up performing worse than a hash map. I don't remember all the details now, but after seeing that I'll just keep reaching for hash maps first (unless I'm sure that there's only going to be a very small number of elements, then I'll just iterate in order over a vector).

Using batteries for all storage use cases is bad engineering. Hydrogen can be stored underground for $1/kWh of energy storage capacity (there is also a per-kW cost, but it is independent of the size of the underground storage caverns). Use that (burned in turbines) instead of batteries for the rare correlated outages of solar/wind, and the cost goes down.

How do you know that Netlify is production ready? I found Netlify Identity to not be production ready* and now I'm not so sure about the rest of the platform.

I don't know why but the issue has lasted for weeks. 3) In development mode, the token can't be verified without making a request to Netlify Functions, and the suggested path (in Redwood.js at least) is to just parse the JWT without verifying it.

The economy grows at a per capita rate of about 2% per annum. The average citizen in 200 years will be approximately 50 times wealthier than we are today.

It makes little sense for the comparatively poor consumers of the 21st century to pay extra for housing for the comparatively rich consumers of the 23rd century. Just as it doesn't make sense for a 20 year old to take out a huge mortgage to buy a big house that he won't need until he's 40 with a big family. It makes much more sense for us poor people or the present to save money by building cheaper, shorter-lasting housing, and let the filthy rich people of the future pay for it later.

First of all, this was many, many years ago. Nowadays my interview is half an hour of (hopefully) nice chat, followed by half an hour of technical questions followed by half an hour to an hour of coding exercise with real IDE.

We all learn on mistakes, my interviewing process evolves as I learn which things do and which don't work.

Second, one of the goals of the interview is to see whether you can deal with the problem analytically. I am purposefully setting up problems that do not require (much) prior knowledge to observe the process of how the candidate deals with the problems.

While our knowledge of particular topics changes, our general approach to solving problems is almost set in stone for similar/related categories of problems.

If you are developer who does not predict how the code is going to work but rather rely on running it umpteen number of times and reshuffling instructions until you happen to make it work, this isn't just a sign of your lack of knowledge but rather your general approach to dealing with them. I bet, and I have observed it many times, that the person will do roughly the same when faced with a number of varied problems.

> I don't know of any approach to interviewing that I think is fair.

That is true, because it was my motivation to build a wizard for behavioural interviews designed to remove biases and be objective. In practice, most of the time people are not even sure what they are looking for - I know it when I see it - and default to gut hiring. This leads to teams made of people that think like you, so you're basically paying 2 salaries for one brain.

My formula for removing biases is in 2 steps: first define explicitly the behavioural traits you desire, and second, use falsifiable questions to determine the truth.

Because we're here to help each other, if this is relevant to you, I'd be happy to share this solution with you.
