TBF he said it would be an open protocol, not open-source. That being said, obviously Apple still never followed through...


Apparently it's some variant of SIP. I'm surprised that it's been a decade and no one has RE'd it all and written an open-source client (or have they all been threatened by lawyers...?)

Duo and WhatsApp have significantly better video quality (especially off of Wi-Fi) than FaceTime


The audio in WA is good, but the video quality is TERRIBLE on WA.

LINE which I use more often is far better quality than WA.


I've found WA to be more stable on the audio front, and video is great as well. But I have an ancient 6s so I'm not quite putting out the highest quality video.


That's certainly true of Duo in experience.


This is demonstrably false. WhatsApp is so bad it makes my eyes bleed.


Eh not really true as they've explicitly stated every single swap / transaction for crypto should be reported vs having any sort of threshold


This is a really really powerful concept – are you hiring?


Thanks! We are. :) Looking in particular for a strong backend engineer. Tech stack is python, aiohttp, redis, postgres (& timescaledb), k8s, terraform, aws (react, nextjs, swr on the frontend).

Know anyone?


I'm interested in learning more

It's really odd that this is making the media rounds now, granted this is the most fair headline I've seen on it to date.

The fact that Focals v2 were being cancelled, and that all customers would receive refunds for their existing purchase was announced with the acquisition months ago...


I love this, but it struck me in the opening paragraph how similar it is to the challenges around training AI on higher-level abstraction goals, with tons of examples of AI's basically "cheating" and passing information discretely to itself to yield answers, rather than actually solving the problem as the human had hoped!


Also - that's not the reason. The reason is because Android is open source and Google allows sideloading.

I don't think Google allows Amazon to distribute their app store through the Play Store, so you have to sideload it.

Doesn't solve the distribution problem anyway – the app stores are the shelf


Sounds very interesting, been in the space for a bit now and eager to learn more. [email protected]


Is real estate still a "great investment" in China when you can't own property but merely buy 75 year leases? (this is my understanding of how real estate works at least in Shanghai)


A couple of things:

1. Everyone expects the leases to be renewed easily and cheaply. There was a huge scandal in Wenzhou when some shorter 30 year leases weren’t going to be renewed cheaply, the central government had to step in to keep up the appearances that the leases were merely a formality.

2. China doesn’t (mostly yet) have property tax. Normal automatic deprecation on property through taxes doesn’t apply.

Now who knows what will happen when a property tax is inevitably introduced...


Both points seem to point to real estate being a bad investment?

1) local governments have already been to tempted to squeeze revenue out of lease renewals, who knows what they’ll do in the future

2) a property tax is inevitable and unknown...


True, but the main reason property is a bad bet is a way too huge property bubble. Urbanizing farmers aren’t going to save the day and pay you $1 million for your extra 75 sqm apartment.


In Shenzhen, the municipality has no issues expropriating land rights of 20 year lease holders.

One my coworker ran into a situation with his landlord:

1. He gets a call from his family "Police knocking on the door, they have an eviction notice"

2. Guy angrily calls the landlord

3. Landlord say WTF and rushes to the scene

4. It was later realised that his flat, that was bought and sold god knows how many times, had its lease expired, and the landlord was not even aware of him having to extend it.

5. He had to relocate his family overnight to friends and coworkers


Real estate is not a great investment in China. It's less bad than the domestic alternatives given Chinese capital controls and financial policies.


Some real estate in Hawaii is also "sold" in this way. The price of "Leasehold" property is generally less expensive than "Fee Simple" property.

Is real estate in America a great investment[1], when despite owning property, you have to pay 2% of its value in taxes/year? In a mere 50 years, the government will own your entire property!

China's property is leased... But as a converse, it doesn't have any property taxes.

At the end of the day, the difference between a fixed-term lease, and a property tax are largely academic. (With a bit of economic weirdness, close to the roll-over period of the lease.)

[1] Which also begs the question - should real estate be a great investment? Nobody cheers when the price of staples and groceries goes up...


Nobody cheers when the price of staples and groceries goes up...

Because nobody buys groceries with massive leverage over 30 years.

People buy houses because they count on inflation to raise the nominal value of the leveraged asset far more than the interest they pay, and usually in the long term that works out and they pay less than they would renting (not always, and renting has upsides too of course).


> People buy houses because they count on inflation to raise the nominal value of the leveraged asset far more than the interest they pay, and usually in the long term that works out and they pay less than they would renting (not always, and renting has upsides too of course).

The problem of course being that for this to be true, housing price inflation has to be greater than general inflation, which implies that nominal housing prices increase faster than nominal wages.

Which is what has happened, but that isn't sustainable, and the math is pretty harsh.

If housing prices increase by a given percentage at the same time as they increase as a percentage of wages from 30% to 45%, then for them to increase by the same percentage during a period of time with the same level of wage growth, they would have to increase from 45% to more than two thirds of wages, which is implausible. To increase by that percentage again would leave them at more than 100% of wages, which obviously can't happen.

So the trend of housing price appreciation above general inflation is inherently temporary. It has to end eventually, if it hasn't already. Note that current housing prices were never really allowed to crash in 2008 and continue to be artificially propped up by low interest rates. So we may be preventing them from falling presently, but that doesn't mean they've got a lot of room to grow any further.

But people who already own property may want them to, or be expecting them to. Those people are likely mistaken.


The problem of course being that for this to be true, housing price inflation has to be greater than general inflation

In real terms I agree house prices oscillate around zero growth (sometimes with decades long periods of higher or lower growth).

However, the leverage makes a difference. If you know bank policy is constant inflation, taking on large debt to buy an asset which tracks inflation makes sense in the long term. Over time the debt becomes less and less significant, and the asset price and yield tracks inflation/wages.

If you could borrow multiples of your wage at low interest to buy stocks for decades the same argument applies - the yield in future will outstrip the cost.


> Nobody cheers when the price of staples and groceries goes up...

Except those who hold the groceries and staples? I'm no investment expert, but my understanding of the value of real estate is due to the scarcity (when taking into account the cost of improvement and demand.)


On the news you'll hear that the housing market has "recovered" and is now "healthy" when prices increase.

When food and gas prices go up we don't say that. We worry.

The narrative has been completely taken over by property owners.


>you have to pay 2% of its value in taxes/year?

Sorry for being naive, that is the first time I heard of property tax in % of value every year! No wonder why so many comments were referring to what happens to China when they introduce property tax.

Coming from places where we have tax, but none of them are as high or based on its property value. Isn't that basically "renting" the property? For a million dollar value flat I have to pay $20K Every year? Or $1.6K every month? That is pretty insane if you ask me.

And why are people continue investing in US housing? So these tax, assuming being paid by its owner, are basally passed on to the lease? So a rise in property value will add an extra 2% effect on its rental pricing?

I would have thought property tax should lower the interest of investment in property, but that doesn't seems to be the case in US.


Okay this sounds crazy, why on earth would anyone tax the market value of the building or apartment? Generally the idea is to tax the land not the property. This way multi family homes can split the tax burden vs a single family home paying the full tax.


You're right. Taxing the cost of the land + the cost of the building is insane.

Unfortunately, that's exactly what every municipality in the United States is doing, right now.

Most economists believe that only taxing the value of the land would be better public policy.


pay 2% of its value in taxes/year? In a mere 50 years

<pedantic> More like 36 years. </pedantic>

There's a quick trick to a good approximation for this. The rule of 72 says that you can estimate the time it takes a compounded investment to double by dividing the interest rate by 72. 2% for 36 years will double the investment (or, since your actual statement was going the other way, strip it to nothing)

See, for example, https://www.investopedia.com/ask/answers/what-is-the-rule-72...


There’s no compounding here, since the property tax is a fee and not a reduction in the value of the asset, so I don’t think that’s applicable.


It's not a direct reduction in value, but I would think if the fee went away the value would still increase.


That's for compound interest. In this case, assuming the value of house stays the same, it does indeed take 50 payments of 2% of the total value until you've paid the full price back to the government.


Assessed value which is usually lower than market value.


As long as one sells their property within 75 years, the investment functions the same as it does in the US. Each new buyer of a property gets a new 75-lease.

At least this is the way my wife (who is Chinese) explained it to me.


> Each new buyer of a property gets a new 75-lease.

That's not a rule, and technicalities vary greatly from one municipality to another.
