It's not bad at predicting what race people will think someone is. Outside of that, it's of marginal utility at best. At worst, it's used for systematic oppression on a global scale.
Look: isn't the same as it happened for microservices, containers, serverless and many other new tech stacks?

It could have been done even without those, but since the cool kids are using them, then they spread
Haha, I wanted to have a bar graph which were by day of week:

Bar 1: Last years deliveries.

Bar 2: Predicted this years deliveries (based on % of increase from other markets if no previous years, or percentage of growth from last 2 years)

Bar 3: Actual deliveries.

Then another graph:

Bar 1: Average processing time from previous year.

Bar 2: Average processing time for current year.

I'm terrible with graphs and such tho, I can get all the data, I really suck at displaying that data tho.

> Even one century is probably more than enough.

Well there you go - they're designed to be temporary - a fifth of houses in the UK are a century old or more, so from experience in this country we don't see a century as being 'more than enough' for a building to last and we use brick to achieve that.
> They start with a conclusion, the justification of race, and seek evidence to prove it. Of course, they find such evidence. Anyone looking to prove any conclusion can find evidence - even scientifically strong evidence.

Can you point to scientifically strong evidence of anything which is also known to be false? I mean evidence which is still accepted as scientifically strong, not something that's been discredited. If not, then I think you've just argued that we can't use science to explain anything because it lets us choose any conclusion we want. I don't think you're trying to promote an anti-science ideology, so can you clarify that?
Penn State and helmets are the risk you bring up?

The canonical example of serverless is for handling web requests i.e. 1 function per HTTP route. Database will still need to be on a static server. Managing user login / state etc. will be cumbersome across multiple different functions, however the email and payment processing handlers may be better candidates for serverless functions. A thin front-end and DB on static servers with serverless used for emails+payment processing would be a good initial architecture

Renting or owning from a purely financial point of view is a relatively straightforward problem and is answered quite nicely with the NY Times Rent vs. Buy calculator (with the caveat that the calculator has not been updated to reflect the new tax laws).

That being said, the biggest reasoning mistakes I run across are:

1. "You pay the landlords expenses plus some profit." Not true. The rental market is just that - a market that fluctuates with supply and demand. There are plenty of landlords who are losing money on their rental property.

2. "Once I have paid off my house I'm done paying for housing." Not true - you still have taxes, insurance, and maintenance whose costs will most likely increase over time.

3. Forgetting about the opportunity costs. Great - you paid off your mortgage. Now you have $500k in equity. Guess what - if you took that $500k and put it in a 5 year treasury you can earn a risk free 3% or 15k/year on that money. Better yet stick it in a broad based index fund and you will grow 6% albeit with more risk. That's your opportunity cost of your equity.

Overall this is such an emotional subject for most. I'm personally glad to see some push-back on the "buying is always better" argument because its been dogma for some time.

There would be no way to raise fees or otherwise exploit their market position for rent-seeking once they had attained market dominance.
I know a handful of people in their 60s...

The ones who made a point to buy instead of renting their entire lives are laughing all the way to the bank.

The ones who are still renting are still working nearly full time and will probably be doing so until the day that they die.

Buying and committing to a mortgage forces you to save money for your future, plain and simple.
What about self-modifying renting contracts? In Germany, some contracts increase 3% every year, not that cheap.

And what happens when you're in retirement and your pension isn't as much as when you were working? Can you keep with the rent?
Pretty sure that's sample bias. People definitely make such complaints about other articles that don't match their expectation of this site.
The “pro renting” crowd has a lot of consistent falacies in arguments:

- Financial calculations ignore the leveraged nature of buying a home. Small increases in property value are multipled relative to your initial investment.

- Calculations also often assume someone just pays the minimum mortgage payment for the full term of the loan. Even small additional principal payments (which most mortgages allow without penalty) drastically reduces the duration of the loan and interest paid.

- “I don’t want to pay those high real estate taxes.” Renters still pay the same real estate taxes, it’s just baked into the rent and can’t be deducted from taxes.

- The tax system is very biased in a favor of home ownership. You basically get penalized at tax time if you don’t own your home as expenses both owners and renters “pay” (property taxes, mortgage interest) are only deductible for the property owner. This can make a huge difference. A renter paying $2000 a month in “after tax” money is spending a lot more than a home owner spending $2000 a month but paying the interest / propert tax portion of that 2k with pre-tax money!

- Capital gains from home ownership are also tax free (up to half a million in gains for couples).

People made the same argument about Apple when the iPhone first happened. "Apple is not going to just come into this product space and get it. It's too complicated."

What we know now is that Apple had been investing in the supply chain and the manufacturing side of things for a very long time before they actually got into this business.

Tesla seems to me to be a company based on the idea of, "Yeah, Apple just went off and pwned the smartphone market, just like they pwned the mp3 player market. So, yeah! We're going to do the same thing. But with cars."

I don't really think that Tesla really understands the situation, the planning, and the investment it took for Apple to really do what it did.
The market tends to decouple from that logic in an appreciating market.

My landlord bought the house I'm in about 10 years ago. His mortgage is a fixed monthly payment that's locked in from when my house was worth less than half it's current value. The rent for where I live tracks really closely to the mortgage rate it'd cost me to buy at it's current valuation. For any investor that bought a rental right now, they'd barely make anything per month. But for my landlord that bought 10 years ago, he nets $1k - $1.5k per month above his costs.

It's also not as straightforward in a depreciating market, either. In a depreciating market, some property owners may rent a property out at a loss, with the expectation that the monthly loss is temporary and less than the loss they'd take it they sold now.
Good points but really a false dichotomy. The purpose of AI and machine learning is to find patterns in data that aren't simple heuristics like this.
> 6% in realtors fees and another 2-3% in closing costs

It certainly varies by region, but in my area most realtors have been pressured down to 5% by Redfin and other competition. Closing costs (which aren't really percentage based) were between a quarter and half a percent on a $700k home.
I realize I'm analyzing a joke, but dollars on the street aren't assumed to exist in an arbitrage free economy because there aren't enough actors. The joke isn't saying that the theory is wrong, it's saying that the economist is wrong for applying it. In the case of housing markets, if anyone can borrow money to buy a house for less than they can make on renting that house, then there are enough people alive that they will do that.

Also, I should mention that this is the zero arbitrage principle and not the efficient market hypothesis. The efficient market hypothesis asserts that everything we know about the future value of a house is reflected in the current price of the house, which is also relevant to the discussion, but not what I was referring to.
In a layman term the difference between sql and ml is, ml predict things and sql just tell you things.

If the competitor is using ml and making gain, then one should also catch up as soon as possible.

There's another intangible benefit to owning if you know you're going to stay in the area long term -- you can't be forced out of your home.

Well, you can. The city decides to put in a new subway line and your house is where they want to build a station. Or (depending on your local laws) the other members of your strata corporation vote to sell the building to a developer who wants to tear it down and build a tower.

But sure, it's far less common for someone to be forced out of a home they own, and when it does happen there's typically years of notice.
> You hold a 5 percent fixed-rate 30-year mortgage.

Is that really so? I've read that the mortgage interest rates are around 2-3% in Europe (by the way, in Russia they start from 9%-11% and can be as high as 15%).

> A house in 1897 cost the same as a house in 1997, adjusted for inflation.

It is hard to believe, given new technologies that are supposed to make it cheaper.

Also what the author didn't take into account - she assumes that she will be able to work forever. But what if you get too old and won't be able to do your job well? What if you get sick? What if you get fired? What if there is a financial crisis? What if the company you work at shuts down?

In all of these cases, a renter will be kicked out on the street (I know in some countries like Finland the government provides free apartment for people who don't have money, but I assume in US you'll have to live in the street). But if you own a house then you can live there even if your income drops. You can live without renovations, you can consume less electricity, you can ask for a tax deduction, you can rent out a room.

Also, an owner can leave a house or an apartment to his children.

The author writes about opportunity cost, that you can invest your money. But it is very high risk. If you invest into a private fund, it can become a bankrupt any time, if you invest into something government-related, tough luck if the national currency crashes. Investing into a house looks like a more safe option.

Of course, there are downsides to the mortgage. If you buy a house or an apartment, it will be probably not in the best location, far away from the center of the city in an undeveloped area, no good transportation around. Because the good ones are too expensive.
Yeah, the parent is being willfully obtuse. Property taxes are taxes that you have to pay merely for holding your investment.

Until this year, you could deduct those taxes up to your total federal tax liability (which may be what the parent is saying), but now you're limited to $10,000. Either way, it's a lot more burdensome than most investments.
Article assumes that if you're a renter, you don't pay insurance.

Which is true for a lot of renters; but they will lose everything if the place burns down. The landlord's policy will not cover the belongings of the renters.

Comparing insured versus uninsured is stupid.
I recently went to a similar innovation conference, that was targeted at business owners. They were proposing block-chain technology as a panacea for every problem under the sun.

Objective-C itself is not verbose, method names can be as long or as short as you like. You can have method names with only colons if you want:

- (void):(id)param1 :(id)param2 :(id)param3

Keyword names do not have to be unique such as:

- (void)drawLine:(id)gfxContext x:(double)x1 y:(double)y1 x:(double)x2 y:(double)y2

Cocoa/Cocoa Touch is verbose, but Objective-C is not (it is by far my favorite programming language)
> A house isn't a depreciating asset

False. Land isn't a depreciating asset, but according to U.S. tax law a house is indeed a depreciating asset.

EDIT: I'll rephrase and say "It's complicated". You can deduct depreciation on a house under some situations because structures are assumed to be depreciating. But a house can still appreciate and when you sell you may be on the hook for gains because of deducted depreciation.

A lesser-known awesome feature of AvantGo was that it also functioned online. In early 2000 I was using AvantGo on a Palm Vx, IrDA connected to my cell phone, getting Internet access via my carrier's WAP gateway (PPP over CSD?

> Generally, with 20% down you are leveraged 5:1. So even if your home is just keeping pace with inflation of 3%, you actually experience 15% growth on your investment.

But if inflation is 3%, you're probably paying 3% (or more) interest on your loan.

So suppose your home costs X. You pay 0.2X downpayment and borrow 0.8X through your mortgage. The first year your home appreciates to 1.03X but you also pay around 3% of 0.8X = 0.024X in interest. So your gain is 0.03X appreciation - 0.024X interest = 0.006X: which is exactly 3% of your 0.2X downpayment! Looks like the leverage didn't help in this scenario at all.

Of course if you bought in the Bay Area a few years ago you made bank, but that's because the growth here happened to be much faster than inflation, even without leverage.

> Sure, you can be leveraged in other investments but (1) your interest won't be tax deductible, (2) your interest rates won't be nearly as low, and most importantly (3) you won't be able to borrow with no recourse

(3) is true, but you can buy stocks on margin, the interest is deductible as a business expense, and interest rates are often lower than mortgage rates.

I think all the hype around block chain is hilarious for the very simple reason that block chain can’t actually solve any business problem that a centrally managed service couldn’t solve (with less effort likely).

The only thing block chain adds to any problem is when you don’t want a managed good or service to be under central authority or if it can’t be under a central authority (the later situation is probably more interesting). Crypto currencies make some sense (though I like my currency backed by the full faith and credit of a government, personally). However every other situation I hear of I wonder why someone couldn’t just manage a central service. Chain of trust on crates of produce? Supply chain professionals have solved the problem of authenticating sourcing of goods quite a long time ago (especially when laws required them too). Personally I think the one benefit that people don’t talk enough about is cases where the block chain can provide its users perfect forward secrecy on their transactions against the ledger, though again you don’t really need the block chain to do that.
Well, in that very obscure case, you are generally legally obligated to something like 110% of market value, so you can't really compare that to e.g. being thrown out because tony said so..

> Is SGML a symbol, identifier, a quoteless string?

It's a sequence of bytes — a string, if you like.

> How do I know when parsing the 'entry' field that what follows is going to be a list of key/value pairs without parsing the whole expression?

You wouldn't, and as a parser you wouldn't need to. The thing which accepts the parsed lists of byte-sequences would need to know what to do with whatever it's given, but that's the same issue as is faced by something which accepts JSON.

> Is 'see-also GML XML' parsed as a list?

(see-also GML XML) is a list.

> How do we distinguish between single element lists and scalars?

'(single-element-list)' is a single-element list; 'scalar' is a scalar. Just like '["single-element-list"]' & '"scalar"' in JSON.

> Is it possible to express a list at the top level, like JSON allows?

That whole expression is a list at top level.

> How do you express a boolean, or null?

The same way that you represent a movie, a post or an integer: by applying some sort of meaning to a sequence of bytes.

> They do not solve questions of maximum levels of nesting.

They don't solve the problem of finite resources, no. It'll always be possible for someone to send one more data than one can possibly process.

> They have the same potential pitfalls with whitespace.

No, they don't, because Ron Rivest's canonical S-expression spec indicates exactly what is & is not whitespace.

> They have exactly the same problems with parsing strings and numbers.

No they don't, because they don't really have either strings or numbers: they have lists an byte-sequences. Anything else is up to the application which uses them — just like any higher meaning of JSON is up to the application which uses it.

> They have the same problem with duplicated keys.

No, they don't — because they don't have keys.

> My point is that in order to match what JSON can do, you have to create rules for interpreting the S-expressions, and those rules are the hard part.

My point is that JSON doesn't — and can't — create all the necessary rules, and that trying to do so is a mistake, because applications do not have mutually-compatible interpretations of data. One application may treat JSON numbers as 64-bit integers, another as 32-bit floats. One application may need to hash object cryptographically, and thus specify an ordering for object properties; another may not care. Every useful application will need to do more than just parse JSON into the equivalent data structure in memory: it needs to validate it & then work with it, which almost certainly means converting that JSON-like data structure into an application-specific data structure.

The key, IMHO, is to punt on specifying all of that for everyone for all time and instead to let each application specify its protocol as necessary. The reason to use S-expressions for that is that they are structured and capable of representing anything.

Ultimately, we can do more by doing less. JSON is seductive, but it'll ultimately leave one disappointed. It does a lot, but not enough. S-expressions do enough to let you do the rest.
