People already had tables of logarithms with lower precision. At the time he did a survey of what tables were available in the world, and it turned out the French had just produced some quite impressive tables, using a lot of manual labor. His value proposition to the British Government was that he can deliver something even better at a fraction of the manual labor (basically only a few people to turn on the crank). The Brits were enamored with the concept of automation at the time, and he made a proof of concept machine with lower precision that he was very happy to demonstrate wherever he would go. Why did he aim for 40 digits? Maybe he did some back of the envelope estimation for the error propagation. If you start with an average error of 10^(-40), then after n additions, in the worst case you can have an error of n*10^(-40). Which is not so bad. But the problem is that in the difference engine you end up adding intermediate results to intermediate results, many, many times over. So if you only look at the worst possible results, you end up needing a lot of precision to start with. Of course, nowadays we know better how to analyze the propagation of errors, but in his time he either didn't know how, or he couldn't convince other people that he can get the total error under control if he used a lower precision throughout. In any case, he completely underestimated the difficulty of scaling the project from his toy example to the full blown final machine.
Who said they hashed it? The correct answer is a 256-bit value, and you're trying to guess any string that hashes to that value. Nothing requires that OP generated that value by hashing a string though...
HTS or stellarators don't have a damned thing to do with those power density limits of DT fusion reactors. Those limits come from power/area on the walls, and they'd still exist even with much higher magnetic fields and plasma beta.
This might be a knee-jerk reaction, but perhaps the reason nobody reported errors in the spreadsheets is because spreadsheets aren't easily auditable, which is one of the reason many dislike spreadsheets being used for this purpose.

If they can consume less electricity than "normal" banking, then they aren't a wast of energy.

The average craftsman home built 100 years ago isn’t going for the same price as a 25 year old house.

The craftsman homes that have survived for 100 years in good condition are. That’s a very different thing.

Old houses also have tons of problems even when upgraded, and they just aren’t anywhere near equivalent to a modern home unless you essentially gut them and rebuild.

Insulation isn’t nearly as good. Bathrooms aren’t nearly the same size. The floor plans aren’t nearly as open. This last one in particular is a big cost difference because creating large open spans is expensive.

Those things might not matter as much to you, but they are big differences.

>The point is that even you wanted to replicate an original craftsman home today, you wouldn't be able to do it for that price, even ignoring regulations. Labor costs have gone up, wood has gone up, minimum cost of every material used has gone up.

Depends on the part of the country and whether or not you can use modern equivalent materials.

Where I live, assuming pre pandemic prices, I could probably build a 900 sq ft, single story house with a wooden pier foundation, no plumbing, no electrical, no insulation (or maybe old newspapers like my great grandmothers house used for insulation), no driveway, no sod, and no inspections for $40-$50k.

That would be roughly equivalent to your average house built 100 years ago.
Because the GP suggests that the only options are (a) not caring or (b) taking other people's money. Clearly, that's a false dichotomy. I pointed out option (c).
The sapwood is an approximately constant radial dimension over the life of the tree once it gets big enough to form heartwood. Sufficiently old trees are more heartwood by percentage than sapwood.

For hardwoods, it's typically the heartwood that's more desirable. Walnut and cherry both have pretty strongly contrasting sapwood that does not match the customer's expectation for the color of those woods, for instance.
Thank you. I do think the people behind this are making a sincere effort to reconcile profit-driven targeted advertising with the human right to privacy -- which may not be possible, at least not without sacrificing a lot of revenues.

The thing is, I doubt a corporation like Google will ever be willing to sacrifice revenue for the sake of privacy, and at the end of the day, the corporation controls the underlying software infrastructure on all Android-branded devices.
You did the right thing. The first three months you find out how you will fit in and if the relationship will work.

> With the rising costs of tuition year after year, it’s becoming unreasonable. And when they’re not dischargable during bankruptcy, it’s giving a middle finger to the poor. Saying, “F you, I got mine” doesn’t solve anything. Something needs to be done about it.

I completely agree. But loan forgiveness, more student loans, or lowering the risk/cost/burden of student loans will only put more money in the system and drive up prices.

Tuition costs are a horrible situation that really needs to be fixed somehow. But loan forgiveness will only make things worse.
Aurora PostgreSQL is based on Aurora, which amusingly traces its roots to MySQL, but that was a long time ago. You can decide how many planks Amazon must install on the ship of Theseus before you're willing to call something "a new database", but the fundamental point is that none of those planks came from MongoDB, thanks to AGPL3.
I remain somewhat obsessed with the idea that you can apply a strong electric field to a cooling polymer in a 3d printer and create a "programmable" electret. That's basically an electric field which is frozen in an insulator. I'm not sure what you could do with it, beyond storing some information (creation and ownership info?) or making part of an embedded sensor, but I feel like there are applications there...
No, it is a hack basically redirecting searches to a custom search engine. Good luck with Andisearch!
Correct! Bitcoin will not go to zero, it will go to infinity.

All fiat, stablecoins, eth, “crypto” etc will go to zero.
Manually is writing code to read and write to the DB. Automatically is writing code, and all the code state (local variables, execution progress) is persisted for you.
This sounds funny, but I get where it's coming from. I think everyone's natural inclination would be to focus on what we think we did wrong and wish had been different, rather than all the things we did right. Grass is always greener and whatnot.

At this age, there are some consequences that you're insulated from. Things that might otherwise destroy some adults' reputations or cause them legal troubles can simply become funny (and/or cringey) memories. I'm not gonna advise a teenager to go do drugs, but I also won't pretend that I've ever regretted the occasional underage drinking I did at the same age; if anything, I more regret having been a bit of a stick-in-the-mud. Just don't touch tobacco or anything harder than alcohol/cannabis, don't do anything while driving, and don't be stupid.

Takeaway here I guess is to just put some effort into having a social life, because in a few years it's going to be harder and the world will be less tolerant of mistakes.

Things I did right: Taking a high load of advanced/AP/post-AP classes. My favorites of those were probably computer science, network administration, Latin, and history/government. I learned a ton, and the GPA weighting meant that I could have a >4.0 GPA on paper while being kind of a lazy student in reality, which helped get me into a much more prestigious university than I deserved. Working at a camp in Maine over the summers was the best thing I ever did.

Things I did wrong: Dropping my athletic extracurriculars (soccer and martial arts) and not taking an interest in my health/fitness; if I could start over, I would get into lifting, running, and keto years earlier. Leaning too hard into my introversion and turning down social opportunities (and girls) without good reasons. Being insensitive or a jerk sometimes, especially for the sake of a "joke". Not taking a gap year before college; I wasn't honest with myself and tried to power through burnout, setting myself up for a bad time. Not wearing sunblock or a daily SPF moisturizer, especially in summer; fuck around with stellar radiation and find out. Not hodling when BTC was at $0.76.

As an aside, I feel terrible for this generation growing up in a social media panopticon (and in the pandemic, but that's another matter). If I were a parent today, I would teach my kids to be very conservative about what they post publicly. Think back to the dumbest thing you've ever said — now imagine it taken out of context, with the least charitable possible interpretation, decades after the fact. A lot of Zoomers are gonna have a real hard time running for political office.

Interestingly enough, handshakes started as a "I'm not carrying a weapon", and that war/combat is essentially a male field.

In reality though, it's very much a male tendency to pursue and display their physical strength; that handshakes also become an avenue for this is unsurprising.
> Yes, if you cut the search space arbitrarily by something like 110 bits or so, the math works differently. So? That's not the game.

See- the search space is already significantly under 256-110 bits.

The search space is a bit smaller than 92 bits in passwordle. If it drew uniformly from the possible characters it would be 92 bits; it's more like 87-88 bits since it does not draw uniformly.

This is out of reach of brute force--- as I've said the entire time-- but if it were just a few characters shorter it would be within reach. 11 is doable with a lot of computing; 9 would be trivially doable. They chose 14 characters of input.

This is an interesting offline-online tradeoff. 10 guesses doesn't get you far vs. a 9 character random password in practice. But 10 guesses with this oracle lets you defeat 9 character random passwords easily. (and provides enough information to defeat 14 character random passwords, but with no feasible search strategy known at this time).

This is very different from "provides no information whatsoever". I suspect you not appreciating this is why we have a difference of opinion.

> Your strategy completely depends on having a list of precomputed hashes for the entire search space.

It depends upon being able to do a meaningful amount of search offline-- either precomputed or before your last guess.
I want anyone to be able to pick up development of the software, not needing permission to do so. If elastic the business goes under, hosted solutions should still be available, with changes still be made on it
"In 1925, only half of homes in the US had electric lighting."

Surely if our goal was to compare prices of TVs over the past 20 years, and if we found that prices of TVs haven't changed, you cannot then claim 'well, old TVs were 720p and modern TVs are 4K, so actually the price of TVs dropped 4 times!'

Today we have all kinds of things that increase productivity: electric power tools, prebuilt parts, laser levels and measuring tools, CAD software, flooring that interlocks, expanding foam that's easilly applied from a spray can, drywall and dozens of things I never even heard of.
Exactly. The lower the risk to borrowing, and the easier it is to borrow, the higher tuition prices will go.

Exposure and response prevention (https://iocdf.org/about-ocd/ocd-treatment/erp), a form of CBT, has helped me a lot. I'm less familiar with other interventions.

In terms of causes, OCD is substantially heritable. I think this sentence from a recent review paper (https://pubmed.ncbi.nlm.nih.gov/34030745) summarizes what's known better than I can: "Despite significant efforts to uncover the genetic basis of OCD, the mechanistic understanding of how genetic and environmental risk factors interact and converge at the molecular level to result in OCD's heterogeneous phenotype is still mostly unknown."

There is nothing weird about packet inspection, and if the VPN or whatever gateway is keyed off the auth of the end application (and not vice versa) it doesn't really matter if it can't necessarily unveil all the TLS traffic. The main concern I have is not that the same sort of protections can't exist at the application endpoint, it's that vendors and developers and IT departments have all been absolutely terrible at doing this. They're not going to get better, they're going to find ways around it.

Whereas, just to pick an example and not as any sort of vendor endorsement, I can have a Palo Alto "VPN" that isn't even using private address ranges but sends user tagging data and performs traffic inspection to stop a compromised but authenticated user endpoint from performing attack attempts on the application endpoint.

Comedy example: The PAs we put it as part of a protection scheme for wide area renewable energy products blocked attempts to update some shitty GE SCADA software because GE was too lazy to renew their signing certificate and was somehow still OK with shipping builds. All the end users had been trained to simply click the "WTF YES I DON'T CARE I HAVE TO WORK TO DO" button. The network control policy did not give them the option.

Application layer proxies can do the same thing, sure, but that fundamentally isn't really any different other than it moves responsibility around.
Huh, That's a sunk-cost fallacy if I've ever seen one.

But also, I love it when people's response to debt forgiveness is "I suffered, so other people should have to suffer too." I guess it's time to start taking people's eyes, it will save us time because we're all going to be blind sooner or later.
You could just look at the data in the spreadsheet instead of speculating?

I kinda think this is exactly part of the point he is making.
Great question! Is it the center of a convex hull containing the extent of territories? Or would you weight it by population? Is it in two dimensions on the surface of the Earth, or in three dimensions?

Consider the possible “center” of France. There’s probably some village in France proper with a monument, but unless you eject Guiana and Réunion I think it must be in the Atlantic somewhere.

The perceived value of the asset has nothing to do with whether something is a ponzi scheme or not. You should read the definition. I'll answer your question anyways of what gives Bitcoin value.

It's value comes from being a digital store of value. Before bitcoin there was none. You had a bank account which was a proxy for physical cash. There was no way to hold the cash personally, digitally, and send it anywhere you want.

Before Bitcoin the best analog was gold - hard to create more of versus fiat which is incredible easy to dilute which is why you would want to diversify out of it. Gold though is slow to send, hard to verify, etc...

Bitcoin basically has the properties of gold in electronic form - hard to create, easy to send, easy to verify, hundreds of thousands of dollars worth can be held securely in your hand.

THAT is what makes Bitcoin valuable. Show me an alternative store of value with those properties.

I once spent a long time building a pretty detailed pro forma model to raise money for a brick and mortar business in a spreadsheet. It was beautifully formatted, comprehensive, and appeared convincing. I patted myself on the back for training myself as an investment banker in 3 months.

I showed it to an i-banker friend that I respected. He barely glanced at the spreadsheet, but offered one thing:

"It's not about how detailed your model is; the most important thing is what your assumptions are."

I was floored. No one cares about spreadsheets for a tech startup, but it turns out even when you're trying to get a brick & mortar, cashflow business off the ground, still no one cares about spreadsheets.

That's probably what folks are reacting to here: the author is ultimately making an point by taking a set of assumptions and using those to derive the point. It seems like the argument is about the assumptions, not the calculations.

In case anyone's curious, here's the model in question. It was for a ping pong social club with food & beverage in NYC:

>Please tell me how the US should have reacted to how they would have won the war while considering your moral principles.

They could bomb military targets, not civilian populations. Yes, Tokyo contained some military facilities, that doesn't justify firebombing the entire city.

The entire doctrine of "bomb the civilians into war weariness" has not been found to be successful, and even in 1944 there were already examples showing that. It more often causes the bombed to rally together against a common enemy, like London in the Blitz or what still effects North Korea today.

Your example of one child in a synthetic fuel facility is ridiculous. I understand that some civilian workers of factories will unfortunately be victims, and that bombs will miss their targets. That's not comparable to wide scale firebombing or nuking the population.

In many places in the US, even in the East, you can buy land for $1000/acre.

An acre is 4046 square meters. A solar module is maybe $75 per square meter. If we cover half the acre with modules, the modules alone cost $150,000/acre. Now add in cost of mounting hardware and inverters.

Land cost is close to negligible for solar, unless you're building it in very expensive places. If land cost ever did become generally significant, PV would be so cheap it would already have driven all other energy sources off the market.
We're the meatmates, and you Zuck.
It's a little more complex than that. You get branches (which manifest as knots in boards) where there's sunlight that can reach the leaves on the ends of those branches.

Trees grown among other trees have to grow up to reach sunlight. The innermost part of the lower trunk might have knots from branches when the tree was young, but once they reach harvestable size, there's a fair amount of clear lumber down low.

Trees grown in the open don't have the pressure to grow upwards, and end up with branches down low throughout their lives (from the center all the way through to the bark). As a result, there's very little clear lumber in them.

Disclaimer, I'm a furnituremaker, not a forester. The above is somewhat better than pure speculation, but likely misses some important bits.
