A mortgage is just renting the money instead of the house. In both cases you're paying for the time value of money. It's just that in many (but not all!) cases you can get a much better deal renting the money than renting the house.
(skimmed paper)

The classic recommendation problem is the following: given a user and the items (mangas) that they like, out of some universe of items (mangas), how can we recommend new items (mangas) that they are also likely to enjoy? Typically this is done via collaborative filtering or some other method, i.e. people who like the same mangas as the original user also enjoy other mangas, so we recommend these to the original user.

A very common problem occurs when you have a new or obscure manga, aka the cold start problem. There are no reviews to use when finding similar mangas (which is our input to the recommendation system). The authors propose extracting visual information from the posters of these less commonly reviewed mangas that finds characteristics of the manga. The theory is that users that like mangas with 'girl with sword' will also like other mangas that have 'girl with sword' or perhaps 'girl with bow' but probably not 'girl with book' (I made these tags up).
I don't get it. This could work if we have a shortage of storage or limited amount of storage, but that's not the case here. Storage is as ubiquitous as air. These coins are not going to be worth much. This is a belly flop waiting to happen.
Apologies! It's an expression I use commonly, like "let me throw this idea out there..." Now that you bring my attention to it, however, it does seems backwards, and I'm sure it's baffling to non-native speakers. Thanks for the heads-up.
True, but none of this has changed recently.

The recent change is the fact that high-voltage semiconductors now make step-up/step-down efficient. In many cases, more efficient than purely using transformers (most semiconductor stuff still uses some form of inductive effect--they just do so at MUCH higher frequencies than in the past which allows them to use MUCH smaller components and get much higher efficiencies).

One of the big advantages of AC has to do with switching. If you flip a switch on AC, within about 10 milliseconds the voltage goes to zero as a natural consequence of the waveform irrespective of what current was flowing previously. A switch can interrupt that without much grief.

If you flip a switch on DC, it has to completely stop the current flow in the presence of a large current and/or voltage that will create a conductive plasma. That means a much larger switch for the same level of power.

There is a reason why your ISP has a huge switch and it is often encased in some inert gas. And also why it sounds like a bomb going off if it trips. And why it takes a hydraulic pump to reset.

Side note: The Pacific DC Intertie was the largest in the world until the 3 Gorges Dam interties--and it dated to the Kennedy administration and used vacuum tubes.

Not really. End of life care can drag on and is expensive. Even if you're really lucky and net $1 million from your house a single illness could wipe that out quickly. Retirement homes cost much more than comparable rent/mortgages.

Nationalization of credit agencies - or even regulation governing exactly how credit scores are computed, and making that information transparent to the public - would be a huge step forward. Credit-determining algorithms are presently a black box to the public.
High-voltage DC is becoming more popular, not less.

The technical advance has been the efficiency of high-voltage semiconductors.

>Yet, without our data, they'd have no business

Yet, without credit rating agencies, you'd get no loans.
It was exagerrated-- the "crime" of liberty dollars is that one of the distributors in NC was the ex-husband of an FBI agents sister, who was bitter about the situation and the FBI Agent decided he could make a terrorism case out of it and in the process steal a great deal of money via Asset Forfeiture-- which they did, including tens of thousands of Ron Paul Presidential Campaign Copper pieces (literally presidential campaign propaganda stolen by the FBI, in violation of the First Amendment and making all involved at the FBI felons under USC 18-242) not to mention something like $6M in Gold, Silver and Platinum pieces.

Then they railroaded the Liberty Dollar defendants with fraudulent (in my opinion) jury instructions telling them that a silver piece 10 times the size of a dime that also has a picture of the statue of liberty's torch was "identical" to US Currency under the law... despite Liberty Dollar having letters from the Secret Service, federal reserve, etc, expressing the legal opinion that they were legal and the like.

It's just a joke.

This case is the one that proved to me that not only is government corrupt, and will steal money, but that it doesn't even follow its own laws, and a large portion of the population will cheer on this corruption (the issue when it got posted to HN was met with a lot of liberals cheering it on because liberals are in favor of the inflationist fiat monetary regime and think that "kooks making money out of silver" should somehow be prosecuted.)
You are missing the point.

People who are heavily in a particular camp where never the target of the fake news. They are integral parts of its distribution but the target has always been swing voters and those who needed a push to get out to vote.

Likewise the purpose of the disputed tags are to give those who are susceptible to influence or not up to date on the news an easy way for them to cut through the noise and get to the truth.
Cash is nice, but the the main point of banks is that I don't have to carry a bunch around. I honestly didn't even use an ATM or carry cash for years. I started carrying cash only when my job reimbursed me for parking (and they only accepted cash). It's also nice for bookkeeping. I can write the account number or purpose on the check itself.
> The situation you describe happens pretty rarely

Statistically maybe but around in the East Bay I have this happen with an Uber or Lyft driver almost once a week. The time I mentioned was just more extreme than the others (typically I wait and they start moving after a few minutes).
You don't have to unfreeze the reports to open a new credit application - the credit app gets rejected (on hold), and the credit issuer will ask you for an auth code. You go to the appropriate agency, log in with the credentials you used when you set up the freeze, provide the request code, they respond with an auth code, you relay the auth code to the credit issuer, credit app progresess.

It basically just forces an auth flow for a credit application, which is quite sane. You can also do the whole process - enrollment and manual authorization - online. It was quite painless for me to do it a couple of years back.
Ask HN: How do you personally measure your financial growth?
I keep track of my monthly budgets, cashflow and net worth in Mint. I use my individual investment sites (Vanguard, Fidelity, etc.) for investment performance reporting because Mint has some weird glitch with my data.

For an annual "year in review" type report for my finances, I'm just starting to get a couple years worth of data in one easy place. What should I really be focused on for that though? I've looked at avg. cash flow, net worth growth rate and absolute YoY growth, investment performance, spending, etc. But I'm not sure what else I should be looking at that I might be missing. Are things like "net worth growth per dollar earned in income"

Curious for what everyone else does when assessing their personal finances and any handy tools you use to make the process easier.
You don’t need to touch the blockchain in order to receive a payment denominated in bitcoins. Every day millions of bitcoin-denominated transactions take place on exchanges using a centralized clearing system (you deposit BTC, transact, then withdraw BTC).

All we need is to standardize this behavior, such that each exchange doesn’t have its own closed system (essentially an SQL database with balances). Rather, we’d using an open clearing protocol, with multiple issuers in the same way we use email with multiple email providers. Each issuer/email provider is centralized, but the system as a whole is decentralized (similar to Git as well).

The simplest example of such a protocol is Stroem[1], which offers trustless micro-payments for consumers/payers, such that only merchants/payees take risks (which are proportional to how often they redeem their BTC on the blockchain). So, merchants get to choose their risk appetite: the longer they wait with redeeming, the lower the per-transaction fee, and the more often they redeem the more the security resembles on-chain transactions, with proportionally higher fees.

I remember this going back at least to The Little Lisper, though they more accompany the text than serve as explanations themselves. The aesthetic certainly leaks into the lessons.
> ah lovely "papers please citizen" and what happen when friend computer with all this proof of identity gets hacked.

While it doesn't solve the "papers please" aspect:

1. Card holds biometric data of person, plus PIN. Card is the only thing that holds this.

2. All card does is output "yes or no" if you are you.

3. You have or use a reader for authenticating who you are. The reader takes you biometric data (fingerprint scan, face scan, or something else), and has you enter your pin. It takes this info, hashes it, compares to the stored info, and outputs the "yes" or "no" answer.

Very basic thing here. 3-factor, and the data about you is never stored anywhere, and the card/reader combo does the rest. The data about you never leaves the card (in fact, it can't - it would be write only for that data).

We have all the technology to do this today. What we don't have is the will. So it won't be implemented.

I'm not saying the above is perfect - but it is 3-factor (what you are, what you have, what you know), and that is what is needed most. The information stays with the owner on the card. All transactions can only be done with the card on-hand to prove you are you. You can change the PIN at will, maybe even the biometric data - but both are write-only, and can't leave the card. The card can read in data (an image for the biometric data, and the code for the PIN), but all it does is hash that together, compare it to the stored hash, and output a yes/no.

I'm not saying the above is perfect, and I am sure I have forgotten something. But it - or something like it - is what we ultimately need. But we won't get it. Ever.
You are not throwing it away. You are exchanging money for a place to live.
Bitcoin tumbles on report China to shutter digital currency exchanges
The problem isn't specific to Facebook.

It's politics in general around the world but mostly in the US where the internet and the rise of confirmation bias has increased polarisation. The only solution is to teach people to be more flexible in their beliefs and increase their willingness to compromise. And this is not something Facebook alone can do.
...except that TSA Precheck doesn't host an OAuth server that my bank can use in lieu of their dumbshit "street you grew up on" nonsense.

But yes, I agree, it's a good point that the government already does this (ditto for lost birth certificates, etc) and this would just be tying the federal identity that they work so hard to verify to a digital one.

"Nazi" derives from the word "National Socialism", it's not inherently German in that regard, they just invented it. The ideology isn't tied to one nation.

I'm going to offer an alternative idea on the rent-vs-buy discussion that I never hear. In most sane countries (not the US) you can achieve non-resident status and not have to pay taxes. In Canada this is possible if you rent, but not as a home-owner. You have to be out of the country at least six months a year and you lose your health coverage.

What you gain is not having to pay taxes. If you're working remotely on a software engineer's salary, that can free up over $50K a year. That's enough to pay your rent, and likely also your food, for a small family even in Canada's most expensive cities.

Taxes are also throwing money in a hole.

I think most people couldn't do it because they have kids (and don't want to homeschool), or one or both spouses have jobs in a physical location, or they just don't like nomadic living. But it's an interesting idea.
Such subsets are readily available in all dynamic languages I've used. But the issue here is really about compile-time checking these things, and that's a different animal.
Our compliance rules dictate a 24hour window before we must share the data breach, in what world does the top personal data overlords have no obligation to disclose in a shorter window? Maybe had they done that, they wouldn't have had time to cash out their stocks before they tanked upon release.
No, the current state-of-the-art in digital currencies completely changes the ballgame, relative to fiat. There's a reason BTC is the main payment mechanism for ransomware.
Fascinating! Thanks for the post, this is why I come to HN. Can you share some more sources from sources you consider reliable and not biased against Liberty dollars, so that I can read more?
I think people generally maintain the homes they own to a higher standard than the ones they rent out. It's not equal in home ownership vs renting. The place I rent has the cheapest appliances possible, paint mostly chipped off on the steps, the flooring is from the 80s, etc.

If you look down a street where I live (Boston area) you can likely guess which units are rentals and which are owned.
If the content is mostly static and the audience is global in nature, then CDN.

If your content is dynamic, needs DB query for every page view then SSD hosting. Also if you are targeting only one country say US, then CDN might not bring that much value. NginX with disc based cache on SSD is quite fast for static content.

It will also depend on how much bandwidth usage you are looking at. For example, something like Linode offers 2TB bandwidth in their $10 plan. 2TB bandwidth on AWS CloudFront will cost you hundreds of USD.

This is a pretty ridiculous statement.

Many companies of a decent size e.g. 100 will have someone dedicated to PR. So we are talking a significant proportion of businesses. And the role of PR is merely to disseminate factual, accurate information about the company e.g. press releases. It's by definition not fake news.
The government inspects buildings, food, a number of things. Somewhat capably. For the record I'm not a big proponents of more government. But something needs to be done about companies irresponsibly holding personal information at this level.
For current UK driving, I estimated that we'd need 10 times more rapid chargers than we have at present, that we'd need about 1 slow charger per 8 cars, as they'd need charging for 1 hour on average per day, and that the current solar and wind power generated in UK would be enough to charge all the cars in UK if they were all electric.

One thing is for certain - a lot less money went into the system than its current face value.

It's the old stock market saying - better to sell on the way up than down.
I'm wholly ignorant to this but I am very curious. Why would it be like that?
I've been a member of many class action law suits. Often the payout is literally pennies, maybe dollars. But I have been a member of one class that received several thousand dollars from one suit. So it can happen, it's just rare.
It would only fail if there was some inherent flaw in the local currency. And, if that were the case, you would likely have a robust alternative economy denominated in dollars.

The Yuan has none of the problems that would allow an alternative currency to really get going.

I suspect Chinese bitcoin usage is mostly a bunch mid-level party bureaucrats attempting to transfer wealth outside China so that they can buy tangible assets that can't be seized.
Easily. That's less than the daily volume on just one exchange:

https://coinmarketcap.com/currencies/ripple/#markets

Of course, you won't get a good deal if you just try and dump $42M worth of Ripple in one sale order. I'd spread it over a week over multiple exchanges.

But note that it will actually be a billion dollars worth of Ripple, which is much much harder to sell.

Tech interviews are 40 minutes max? Where are you interviewing?

I have seen far more 6+ hour interview loops that 40 minute ones.

Maybe each session within the full loop accounts for 40 minutes.

That being said, people have their pet questions they use to sort the wheat from the chaff--if you can't fizzbuzz your way out of a wet paper bag, I am not hiring you. The best questions are more about process than the final answer. Solve an easyish problem, add some features, add some more features. What other ways could you have solved that problem? Why did you choose this way? When would you use a different approach? How does your solution scale?

The worst questions are gotcha questions with a right and wrong answer, `what does the C99 standard indicate is the correct size of a stack frame?`
I think this is a great idea!

That not true. Ph.D. in University was making the same wages as cleaner working in said University. You underestimate how ridiculous was communism. My parents after getting Masters choose to go into farming as it was better money.

Everyone has plenty money but you could not buy anything, you needed a special token to buy for example new fridge. Used products were more expensive than new. You needed to wait for everything.

People did not revolt because of propaganda and in a technological leap that happened after the war. In 1950 you will still go to the city on the horse but in 1980 everyone had running water, TV, electricity and at least a one car per village.
Although I'm sympathetic with the side I think you're on, the legal issue at stake here is much more complex than you are giving credit for, and reasonable people can disagree about this. Courts have apparently found in the past that disclosing a physical key is not a 5th amendment violation whereas disclosing a code (eg the combination to a safe) is. The EFF is apparently of the mind that this is a violation. There's a decent writeup of a different case that raises the same issue here http://www.outsidethebeltway.com/the-fifth-amendment-privacy...

My brother, only a few months after buying his first house, had a tree in the backyard get struck by lightning, break in two and crush his neighbors garage.

The neighbors insurance paid for that, but then he still had to pay almost $3000 right away to get the rest of the tree removed from his backyard, because it was still in bad shape. Was an unpleasant introduction to the wonderful world of home ownership.
In addition to less expensive cities, in many in-demand cities (SF not so much), it's actually possible to live in many nice suburbs/exurbs for a lot less money. That's often even where most of the tech jobs are.

Boston/Cambridge? Expensive. But 45 mins or so out? Far less so. And you're closer to where most of the jobs are anyway. The urban cores may be a lifestyle choice. But it's a luxury choice in many cases. Not a place that someone actually has to live if they want to work.
It's interesting to read the reasons behind some of these decisions. What frustrates me as a buyer though is the process of buyer remorse when I dint fully understand the options in the menu I buy something that sounds good but is not what I wanted as I just wasn't able to parse it correctly.
Daily volumes on exchanges is usually > 100,000 bitcoins, hence USD$~413,900,000 at current price (source: https://data.bitcoinity.org/markets/volume/24h)

If you wanted to liquidate USD$1,000,000,000 over a quarter (~90 days), that would be USD$~11,111,112 per day, a bit under 3% of the daily volume. That would probably have a small negative impact on the price.

Moreover, if you were that size, you'd probably go through over-the-counter shops (such as https://cumberlandmining.com/), reducing your slippage even more.
Mashape was recently sold and it's taking 20% off of everything. Too expensive...

The property group takes on risk if something like a roof needs replacing unless they just keep a lot of cash sitting around for just such a thing. They may also have access to better loans but I have no idea for sure.

I don't want to keep a pile of cash around waiting for housing emergencies (personal emergencies are a different thing), and I certainly don't want to sell stocks to fix a roof if my roof fails during a recession.
Credit algorithms, specifically your FICO score, are not transparent. There is no reason beyond the naive assumption of good faith on the part of these companies to believe that they don't make or break at least your credit SCORE.
Arguable, and they are still working within/for the government. I have little to no faith.

Yeah, it's basically like insurance. You're not hit with a sudden $10k+ bill, you just have a rent that has ~$100 a month factored in for maintenance costs.
