I always think it's amusing that people assume that before the internet nothing like this could possibly have been done.

Here's how it worked before the internet: You the property owner would engage a local estate agent [realtor] and they would find tenants for your property. There were both short and long term rentals. Most of the time it would be rented out to someone local. But if someone from another country wanted to do a short term rental, they would contract a company who would have a presence in the foreign country and would in turn be able to contact local estate agents by telephone, get particulars sent through the mail or fax (or if it was really urgent, read out on the phone), and these would find their way back to the prospective tenant.

Sure it's not as smooth as clicking on a website, but it was still a thing that was done.

(In fact these intermediary companies still exist and are still used especially by businesses that want a full service and don't want to deal with the randomness of Airbnb. I knew someone who worked in a Japan-England company back in the 90s http://www.redacstrattons.com/)
I think the flip is more the reason to do delivery/curbside. Symptoms aren't always present so you going into the store could be exposing many people to infection.

Delivery isolates. Yes your driver and handler could be infected, but so could you.
That's risky though, it's possible to get ruined by buying futures (or put options for that matter) since it's basically a contract that must be fulfilled at some point in the future. AFAIK normally they function as insurance for buyers and sellers, to create more market stability.
The JVM also has full information about the class hierarchy at runtime. If you add a class that overrides a function it will deoptimize that overriden function to a virtual function but otherwise the JVM will just treat it as a static function and inline it if necessary.
True, but tight oil production that was previously though to be impossible to extract economically has more than offset losses in conventional production. Peak oil predictions of decades past presumed this could only happen when oil prices rose so high that alternative energy sources would be competitive. Therefore these reservoirs would remain uneconomic. Instead fracking got really cheap.

That’s too absolute: nobody is arguing that there’d be a 100% purchase rate but it seems highly unlikely that there will be no sales impact from having free copies available from a reputable source with very high search-engine ranking.
>Why would you trust an unknown group of people to take all the proper precautions? Who picked the item by hand? Who is this bringing it to your door? Are you sure they washed hands? Did they accidentally sneeze on anything? Is the vehicle sanitary?

All of these risks are already present from the stockers and checkout at the grocery store, which is why you should wash/cook everything they touch. Even if most of your items are contaminated, you can still keep yourself safe.

>I can keep as much distance from people as I want.

They can also get as close to you as they want, and one unlucky interaction can make you sick. Limiting your contact to one driver who will do what you say is safer.
As someone who lives in a (already expensive) US-based short term & seasonal rental hotspot, I have been consistently subjected to 10-25% annual rental increases for going at 7 years straight now.

Many peers and locals have emotionally or otherwise fought against the rise of these short term real estate schemes. Something to the effect of "Neighborhoods are for neighbors" as the slogan goes...constantly griping about it one way or the other.

But it's a personal choice to putup, so I just shutup and carryon while appreciating the city that much more. Yes, the trend has caused me financial challenge and the inconvenience of having to relocate around town more often that I'd like, creating stress and sacrifice, but I've always accepted and adapted.

Now here we have the black swan of 2020 and the airbnb money tree has dried up died in the scope of <2 weeks. Properties that typically gross 10-15-20k monthly during peak seasons are suddenly at or approaching ZERO rental income.

The amount of these properties in my area is conservatively 50%, though would some say 75-90%. Tough to know forsure given the 'rougue' players. If you add up the volume, density, and exorbitant prices - this is going to be a massive overdue fallout in residential rental rates.

So let the market correct itself and find a new low/equilibrium. May the highly-leveraged, over-extended, get rich quick get lost quick ... and with that put all these prime properties within reach again for those who do call this city home and hold it down year round.

Clearly, I welcome the chaos ;)
Another thing worth mentioning is Scanimate which was an analog video animation system used in the late 70s/early 80s to create a lot of the flying/metallic logo effects that were common on TV at the time.

I have to say I agree with the authors guild on this.

There must be rules concerning intellectual property. Laws are the rules our society lives by, and when a prominent public organization decides to willfully break copyright law in this manner it harms everyone.

Copyright law is messy and there are many unintuitive parts. Educating people about the details is difficult and this change they have made is essentially teaching people that it's ok to steal IP.

It's not ok.

I guess that to build it "for its required purpose" is implicit in the sentence. I agree, that the author could have gone into more detail of what are the requirements of cooling towers but that may be out of the scope of the article.
Options Trading would be one approach. You don’t need to actually buy the commodity itself, but instead an option contract that permits you to buy the underlying ( stock, commodity ) at a particular rate by a particular date.

If the price were to rise in the future, the value of the contract would be much higher than what you bought it at, and someone interested in further trading in the options contract or even buying the actual underlying world more pay the market value of that options contract to you.

I just checked: the current price of a single options contract of crude for 18 Sept at buying price (CALL) of USD 10, is 0.3. So buying a 100 (the minimum), would cost about USD 30. Now, ID between now and September the price of crude were to shoot up, then the market price of this option would likely rise.

Unlike stock, though, Options expire. But unlike stock, you get to buy the rights to buy or sell at a particular price and thus the capital needed is far lesser.
I believe calling out something for what it is, is just fair.

Just like calling out Milli Vanilli was in order.

The Java ecosystem is the size of a mid-sized country. I love Clojure but the small tip of Java (language) developers doing extremely interesting, unusual, creative stuff (like, say, controlling robot swarms [1] or marine robots [2], or sophisticated formal methods tools like for TLA+ [3] or Alloy [4], or computing orbits for NASA [5], or embedded hard-realtime for cars and manufacturing [6], or games like Minecraft) still outnumber all Clojure and Scala developers working on creative unusual stuff at least 10 to 1. It's just that in a small pond it's easier to spot a few islands of creativity than it is to spot the many such islands in an ocean.

Peak Oil (conventional) happened in 2008 (see World Energy Outlook 2018 from the IEA). Tight oil came to the rescue. Tight oil and shale oil industries are all built on a huge amount of debt and never were cash-positive in the past 12 years. That's the part that wasn't anticipated.

However shale oil requires constant drilling because production rises then falls very quickly (18 months to 2 years). With low oil prices, drilling will dry out and oil will dry out soon, too. Plus total oil production (conventional + non conventional) will probably peak anyway in the next decade (see WEO 2018, once again), and this may be quickened by the coming lack of investment due to low oil prices.

What could happen? With low demand and low price, the non conventional oil industry is deemed to go bankrupt, and the US banks will have to part with trillions of debt. That won't be pretty. Until this industry is rescued and starts pumping again, there could be a severe crunch of oil production, initiating an oil shock and a huge recession, sometimes in the coming next few years.
That is an interesting connection I will have to keep in mind. I don't think that would be an issue for the first link at least, which only looked at additional cancer deaths in the US and OECD due to the recession.

The article says to apply a curvature opposite to the direction it sags in. Whether it's a full 180 degrees or not doesn't matter, you get the effect with any amount of curvature.

Actually, if you fold it totally flat then presumably you'd lose the curvature and it would sag again, so that seems unoptimal to me. Plus, how could you taste the toppings?

They do, it's just not a priority. The PEP I linked (as well as most of the work of its author, Victor Stinner, in the last years) are motivated by JITing.

There's also the "frame evaluation API" PEP [1], whose purpose is to allow pluggable evaluators in CPython without forking the entire interpreter, like Unladen Swallow had to.

> The Java JIT has static type information to work with

I don't know that the java JIT has type feedback. However regardless Java being statically typed means Java code is structurally closer to what a JIT wants and can analyse, it's much more difficult (and thus rarer) to fuck around with types and objects generated on the fly at runtime for instance, you're not going to add new attributes to an instance whereas that's just tuesday in javascript.
Something in line with the claims of the copyright industry... "revenues not generated by the rental agreements".
Yeah, it's certainly more prolonged though even the extreme on that range is a 7x delta.

The $10 barrels are for delivery now, not next year.

If you can store the oil you can earn a lot of money now. But most people can't store much oil, compared to the volumes that are being pumped out of the ground. And for many of the producers, slowing down production by more than a few per cent is also difficult — once you turn off the tap you don't really know whether the oil is going to start flowing again later. So the effect is a steep price fall.
Nope, discoveries worldwide peaked 4 decades ago. Production follows discoveries with a 4 to 5 decades delay. For scale, we need to find out about a new Saudi Arabia every year. We simply don't.
Did they want money too? How much?
So the language itself is the limiting factor, being dynamically typed. I imagine sometimes what we’d get if typescript were natively supported. People could still write JS, or add the type information which would then allow higher performance to be achieved - approaching native or Java/C# levels.
The market is broken because demand is way down, but production isn't being lowered to match. Saudi Arabia intends to keep their production high. The other producers are losing money but haven't reduced output, because changing output levels is more expensive than taking the loss.
The fake news company takes a photo of a protest. They then deepfake a celebrity into the photo, invalidating its cryptographic signature in the process. They then print the photo, and take a photo of the photo.

Their photo of the photo now has a valid cryptographic signature that proves it's real and trustworthy.
> many unintuitive parts

I think a more concrete term for unintuitive is outdated. The use cases for Copyright law were defined a century ago when society and technology was different. It is difficult for current citizens to understand copyright law because has nothing to do with their own day to day experiences and needs.

Great video about Copyright by Tom Scott: https://www.youtube.com/watch?v=1Jwo5qc78QU

Too long didn't see: Copyright is broken needs to be fixed in a way that fits the current situation and needs, but, it is going to be damn hard to do.
They don't really need to "abuse" these relief regulations (I'm not sure they are even doing it, because I'm not sure if the protective regulations actually cover commercial rentals, which are generally much less protected by law than private rentals).

The landlords of these shops don't have any incentive to throw these merchants out because of a few months of missing rent during a time in which most retailers are forced to close. Where should they find any alternative tenants for these properties? Nobody could even move in right now, much less sell anything there. The first time at which they could potentially find someone to market these properties to is when the restrictions on the already-existing tenants are most likely being lifted as well, which means they will start paying rent again.

The only risk for the merchants is that the landlords might take them to court in order to make them pay the missing rent. But that is a rather calculable risk, these big merchants all have legal departments able to handle this risk, and even in the worst case (they are made to pay the full sum) these court decisions will take months until they come into effect, so the primary goal of conserving liquidity during the forced business shutdown time has already been achieved.
Probably because if I'm going to wait four days anyway, I'll probably just say "Gee, guess I'll just drive down there and get it".

This article is an eye opening read. They didn’t choose paper because they were old fashioned but because their students all lived in an area without internet or any retail infrastructure. They also distributed corona virus info because the parents were (naturally) in the same boat.

> it becomes a never ending adversarial AI arms race

SOTA model training now costs up to 7 figures. Creating deep fakes that couldn't be detected by some 8 figure SOTA model might not be worth it; definitely no regular Joe Deep Learning researcher could make one at some point. Then it will be done only for high value targets by some large corporate or government bodies.
Regulators might be able to legislate food into existence in counties with strategic reserves, but not all places are so lucky. If there isn't enough calories produced, people would die. Most in low GDP countries which are net food importers.
> Why is grocery delivery considered a ‘safer’ option than going to the store yourself.

If we both go to the store, you can infect me and the people working in the store. If the store delivers to you, it is easier to make sure you (the customer) do not infect anyone (they can leave the goods outside, no need for close interaction).

As others mentioned, a lot of people will interact with the goods before you - but it is much more feasible for a store to train and equip a handful of people to take precautions, than to expect the public at large to do so - just a simple thing like not being able to change in a proper wardrobe before entering the store, means customers are a lot more "dangerous" than staff.
Congratulations, you've repeated my question exactly while saying absolutely nothing else.

I strongly suspect that they're talking about an actual mathematical minimization result, such as how a sphere minimizes surface area for constant volume, and the journalist just didn't bother to understand what the claim was before repeating half of it.
The oil isn't just magically coming from some unstoppable font.

They're going to have to bite the bullet and shut some wells. They say as much at the bottom of the article. It's not like we haven't had oil downturns before...
"Peak Oil" was the idea that the demand for oil would exceed the supply we are able to access. Yet we keep finding more and increasing our ability to access more thanks to technological progress.

But mostly, "Peak Oil" fears were ginned up by a press who love to promote tales of doom and destruction. Those trumpeting the threat of "Peak Oil" demanded broad governmental and social intervention to avoid what was assured to be a massive economic disaster. There were assertions that those denying the threat of "Peak Oil" were the Neville Chamberlains of their time or villagers refusing to vacate under the imminent threat of volcanic eruption.

No mistake - oil has a fixed supply. It will run out. But it turns out that won't happen for some time.

It will go back to the same level. Nobody likes the situation right now and once the threat of death and disease disappears people will begin to behave as they once did.

Our entire culture and urban physical infrastructure is built around a certain level of oil consumption. The current situation is temporary, the real solution is to replace the source of energy of fossil fuels. We are projected to have green energy be 30% of all energy consumption by 2024 with much of this effort lead by China.

The extreme central control and lack of freedoms that the western world hates so much is exactly what makes China so effective at protecting themselves against COVID-19 and saving the world from an energy crisis. We value freedom but the cost is too high.
