These planets would be accelerated at SMBH mergers, which would occur in galaxies. Yes, once the planet gets to a void it's hitting less gas, but it has to get out of a galaxy and galaxy cluster to get there, and that will take many thousands, perhaps millions, of years.

The outer fringes of the Earth's atmosphere are hydrogen, but the density there is so low that these cosmic ray particles would be unlikely to interact there. Also, the neutrons here are FAST neutrons (the (n,p) reaction on 14N is a fast neutron reaction) so they are traveling at very high, if not relativistic, speed, and would not have time to decay before they react (or are thermalized and become irrelevant to 14C generation from 14N).
I suspect doing personalised ads obliterates any caching method on cheaper hardware than transcoding servers. Interesting problem to solve though.

>> Contemporary core counts coupled with very wide simd makes CPUs functionally similar to ASIC/fpga in many cases.

> I don't think so. For things that have a way to be solved in parallel, you can get at least a 100x advantage easily.

That’s kind of my point. CPUs are incredibly parallel now in their interface. Let’s say you have 32 cores and use 256 bit simd for 4 64-bit ops. That would give you ~128x improvement compared to doing all those ops serially. It’s just a matter of writing your program to exploit the available parallelism.

There’s also implicit ILP going on as well but I think explicitly using simd usually keeps execution ports filled.
“This sounded to me like” is the problem.

YouTube needs to re-encode occasionally (new codecs/settings/platforms), it would be easy to abuse and send too high bitrate or otherwise wrong content, and a lot of end-user devices simply isn't powerful enough to complete the task in a reasonable amount of time.
You wouldn't even need to do real-time encoding for that, you can simply mux them in at any GOP boundary (other services already do real-time ad insertion in MPEG-DASH manifests)

Example: https://www.youtube.com/watch?v=LFHEko3vC98
RFID is not capable of serving ads on its own. They're basically just wireless barcodes.

In any case, privately funded anything for roads only works on very heavily traveled roads where there's enough traffic to justify trying to reach out to potential customers that way. Your quiet suburban street, mountain road, or rural interstate is not going to generate enough traffic to pay for itself, so it won't happen. And billboards and roadside advertising are not even legal in all 50 states of the US, let alone other countries.

How to create a file by file custom SCSS build incl. dependencies, using postcss
TL,DR: What are the problems to solve for efficient CC?

Answer that's missing in the article:

CO2 is one of the stablest elements in the atmosphere. Removing it will require humongous amounts of energy (as a rule of the thumb, more energy than the energy-producing process that generated this CO2 in the first place). Therefore CC at scale is probably a pipe dream and will remain so, because thermodynamics.

I find the 99 year lease thing in Singapore fascinating so have done a bunch of background reading on it. You are correct that most of the leases are good until the late 2000's (since most construction happened in the 1970-90's, but there are some properties built in the 1960's that are on the "downhill slope" of the lease - basically the remaining time is less than the average adult life expectancy (say buy at 30 and live another 60 years).

As you said, it's going to be interesting when these start to "expire" in large quantities. What the conversation has been in Singapore so far:

- the gov't will "buy out" the remaining lease for some developments and put up new housing. Existing owners will get a payment and a new subsidized house. However, the gov't has said this will be rare (the problem was when this started is people assumed all owners would get this deal so housing prices jumped, even on properties with little lease life left).

- if you do an NPV analysis of the value of a 99-year lease, it's pretty much worth the same as a freehold lease for the first couple of decades, then it starts to be priced as a true lease - e.g. what would the NPV of renting it be for X years? that's the purchase price. So if a home rents for $3k per month and has 2 years of lease left, the purchase price would be $72k (minus any time value of money)

- the Singapore gov't has also said that it will be proactively initiating the lease-end process 5-10 years prior to avoid masses of people dealing with expired leases at the same time.

Well transistors are cheap and synchronization is not a bottleneck for embarrassingly parallel video encoding jobs like these. Contemporary CPUs already downclock when they can to save power and conserve heat.
To add, currently users can switch off searchability of their profiles. In addition, I think you are right; it would be good to have options to:
'Open network' - anyone can follow
'Closed network' - approve followers..
There was actually an exeption for people that lost someone in the DSM. Following long debates they ended up removing it.

What seems clear is that in a lot of cases depression seems to be a normal reaction to worsening life conditions and not merely a brain chemicals imbalance. So I think it's wise to remain careful around what can be considered a depression and whether it should be considered a symptom or a disease.

Tangential thought; aren't compressed gas companies who bottle CO2/Nitrogen etc. technically carbon capturing?

Tech used:

- AWS / Serverless
- React / NextJS
- NodeJS

>> It seems to me that if you are ten times as rich as me then you will use less than ten times the land value I do
> Why?

The world's richest man own $500m of real estate. Sounds like a lot until you realise it's 0.25% of his net worth (and the unimproved land value's possibly sub 0.1%)

What percentage of the average American's net worth is tied up in the footprint of their home? Guess it's two orders of magnitude more than Jeff's, and potentially >90% of the value of the average farm. Hence not remotely progressive, even if it's less worse than a pure property tax in most circumstances and other even more regressive taxes.

> As far as I understand, the vast majority of the farms are on rural land that has an unimproved value of close to zero. I don't see how they would pay much taxes.

It takes a lot of land to make a farm. (Sure, per acre it's less than the city, but city dwellers don't own many acres and unlike the farmer have a realistic proposition of selling their limited acreage to a condo developer when the tax makes it unaffordable).

c.f. It takes zero land to make a much higher margin SaaS startup.

wat?

I honestly can't parse this sentence.

"Google creates dedicated custom proprietary processors which can process VP9 at roughly the same speed as a 20-year-old codec". How is this a win for opensource codecs?
Intel has had PCIe cards targeted at this market, reusing their own HW encoder, e.g. the VCA2 could do up to 14 real-time 4K transcodes at under 240W, and the upcoming Xe cards would support VP9 encode. (XG310 is similar albeit more targeted at cloud gaming servers)
Clicked into a couple random videos, looks like all of their video IDs are 11 characters, alphanumeric with cases. So 26+26+10 = 62 choices for each char, 62^11 = 5.2e+19 = 52 quintillion unique IDs (52 million trillions).

So, yeah, sampling would be a mostly futile effort since you're looking to estimate about 8 to 10 decimal digits of precision. Though it's technically still possible since you'd expect about 1 in every 50 million - 5 billion IDs to work (assuming somewhere between a trillion and 10 billion videos).

My statistics knowledge is rusty, but I guess if you could sample, say, 50 billion urls you could actually make a very coarse estimate with a reasonable confidence level. That's a lot but, ignoring rate limits, well within the range of usual web-scale stuff.

I recall something about movie studios setting up their business so that a successful film can technically be a flop because of all the internal billing. I recall this affecting royalties to those involved in making because it supposedly made less money.

Is the same thing going on here? Is Amazon unprofitable in Europe because it’s billing itself from another Amazon entity outside of Europe thus wiping out the profit?

There was a time when we gathered a group of friends to order books from Amazon (USA) to Spain to share shipping costs. We were students and waiting a month to save a few bucks was worthy.

I'm buying less and less from Amazon recently. And I no longer "go shopping" to Amazon and just go there to check prices. I think other companies are catching up and I was surprised when my latest laptop was delivered from a traditional retailer (El Corte Inglés) in under two hours. Just to share some anecdata.

That's not what happened. The European Commissioner for Competition decreed that Apple had received illegal tax benefits from Ireland and ordered Apple to pay a fine of €13 billion. This was appealed to the European General Court, which ruled in favour of Apple and struck down the Commissioner's decision as illegal.
> Terrible article, Amazon didn’t pay profit taxes, because Amazon didn’t make profits but instead, a loss. How is this an issue?

Because if Amazon makes a loss on selling 44 billion € of merchandise, either Amazon is incompetent beyond belief or they engage in somehow-legal tax dodgery at the expense of European countries whose infrastructure they mercilessly wreck.

Simple logic leads to the latter explanation being more likely.
