>All public transit initiatives from Elon Musk seem to show that he's entertaining a vision where everyone keeps their own car, with their own Tesla tunnels to get home.

I'm not a fan of most of his public transit projects, however there is nothing about them that dictates who owns the cars. It isn't likely that Tesla would block a Tesla owned Tesla vehicle from using those tunnels in favor of a privately owned Tesla vehicle.

>I find this idea that people would be willing to share a car with the whole world pretty naive, majority of car owners are likely to want to keep their cars for themselves.

Will everyone participate? Obviously not. However, the Ubers, Lyfts, ZipCars, Turos, and even the Enterprises and Hertz of the world show that many people would happily share a car given the right circumstances. There doesn't need to be 100% participation to reduce the number of cars in existence.
There aren't actually "variables" in Python in the sense of named values, instead there are namespaces where values are stored and looked up under string identifier keys. (Just to add spice, some values, namely function and class objects, do get their names embedded in them, but this is only used for debugging. They are stored in enclosing namespace dicts like other values.):

>>> def f(): pass

>>> g = f

>>> g
<function f at 0x000001B4A686E0D0>

Except a lot of projects aren't shipping anything to anyone, they are providing a service. There, you have to assess the effect if the service goes down or is compromised.

Making two teams compete like that is a horrible idea. Both teams know that no matter how hard they work, their work may be thrown away. I've heard horror stories like this in a post mortem about the development of Sonic 3D for Saturn back then for example. There were two teams tasked with making a sequel, and only the better one would be released. Management's idea was that it was supposed to be a flagship title and had to be good. Both teams worked themselves to exhaustion and almost everyone quit the company, the rest got fired due to failure.
Yeah - our core thesis is that the demand has always been there, this is why people travel into cities on weekends for food. And if we can make it way easier to access then people would have nice dinners more. There was a study that 40% of Americans would like to eat out more than they do now.

Certainly there is no difference between them in terms of their human dignity and (unless otherwise specified by law) their rights as citizens. But it seems illogical to assert that there is no difference at all between a person who has broken a law and a person who has not...
Correct, but the properties of Bitcoin are baked into the protocol and not up for policy debate. The Bitcoin Core people can't get together and cause massive inflation, wiping out everyone's savings and lowering the value of their salaries.

Most importantly, no military is needed to secure the value of BTC. The US is in a constant state of warfare to keep its position on the top of the world hierarchy, which is what gives USD the value it has.

This. Even relatively simple websites are much harder to parse today. I did a minor side project for a customer scraping some info and anti-scraping measures were in full force. It feels like an all out war.
But they were at the time, a technology company. Technology isn't defined by silicon and code, but by the fact that a company grows by inventing new things. Google may be on track to becoming an advertising company, but they seem damn resistant to the idea given how many of their new businesses they're burning through to find new revenue.
Exactly. I can’t believe the number of people who think that BTC is some magic shield against the powers that be.

> majority of car owners are likely to want to keep their cars for themselves.

I can bet that in most big European cities, relying on public transportation + renting a car whenever you need is cheaper than the maintenance costs of car ownership (parking + insurance + gas).

Making the car rental more efficient on a global scale will reduce the need and the utilitarian value of car ownership. There will be of course those that will want to have their own car, but that will be more and more considered a luxury item or status symbol than a need for anyone living in urban areas.

Bitcoin settles a very, very tiny proportion of transactions. All of crypto has <1% of global amount of transactions, so they aren't offsetting anything meaningful.

Visa, Mastercard, Unionpay, SEPA each settle more than 100 billion transactions per year, bitcoin has less than 0.2 billion transactions per year. Currently bitcoin consumes something like 0.25% of world's electricity for much less than 0.25% of world's transactions, so if we processed all transactions this wastefully, it wouldn't be enough to divert all the power production in the world to do so.

quibble on "you're". It's a shared planet, so it gets ruined if enough mining is done on non-renewables. Most people complaining aren't mining at all.
Yep, so... a quick glance at this site [1] suggests that revenue from transaction fees is slightly over 1/10^th the total revenue from mining (avg of last 7 days).

That would move my estimate of 100kwh to 1000kwh... still the same order of magnitude as the original claims.

Very probably I'm missing something, and I love Let's Encrypt and the service that they provide, but... the point of Let's Encrypt is to bring SSL/TLS to more websites, right (and not necessarily to provide identity verification, since the automated renewal process doesn't really require any proof of identity for the entity requesting the certificate)? Why couldn't that have been accomplished using self-signed certificates, and having browser vendors remove their big scary warning pages for sites using self-signed certificates for SSL/TLS?

I might be wrong, but I think it comes down to a lot of tech people on here being aware of Bitcoin early on, yet they didn't research it more or invested in it, wrote it off and now it's value is constantly increasing. I suspect they resent others who have invested and are much better off because of it.

This is just personal opinion and I'm sure there are other people who disagree with the electricity consumption or some other things as well.

This first-google-result analysis[0] from a couple years ago puts the global banking system at around 100 TWh a year which is pretty close to the currently estimated "121.36TWh" for bitcoin[1].

Incidentally, that 2nd article mentions that this is equivalent to the power used by inactive-but-on electronic devices in US households alone.

I guess PC gaming was at 75TWh 5 years ago [2], so I'm not going to worry too much yet.

That he is on duty is irrelevant. If he's playing music for himself - even one other person, it's not a public performance.

The arguments being made here are infantile, and embarrassing.

Because people 'hate cops' (shameful), they use magical thinking to twist even common sense upside down.

The person making a video public is the person making something public, not the cop.

Where do you think energy being consumed comes from?
In that case, write them a cheque?

If you don't want irreversible transactions, you don't want bitcoin.

My point is that claiming bitcoin is or isn't inefficient relative to other systems is nonsense. There's simply no comparable system that has the same guarantees as bitcoin, presently or throughout history.

As far as we know, the power cost of bitcoin may very well be the minimum required energy to run an irreversible proof-of-work distributed ledger. Maybe spending 1% of the world's energy to have this public infrastructure is actually a good deal? I really don't know.
Even with bitcoins just consider what happens once all bitcoins are mined. Does the whole thing collapse? Or do bitcoins continue to be used similar to POS?
I actually did the math on this once, believe it or not.
Based on where I live (fairly high carbon emissions from our local utility, though they have deployed more solar recently), switching to an all-electric car would have roughly the same effect carbon-wise as moving to a 60mpg car. YMMV.
My math may not be perfect, but it seems that while not a perfect solution, switching to electric cars DOES improve efficiency somewhat carbon-wise. I'm on the side of not letting perfect become the enemy of good.
For bitcoin to use an equivalent amount of carbon as visa per transaction, it'd need to be 99.9999% powered by renewables and visa would need to be 100% powered by fossil fuels.
Exactly right. All needs to do is outlast everything else. This where the store of value narrative comes from.
I’ve wondered why California doesn’t leverage Prop 13 to encourage more housing units. Say for any property which isn’t owner occupied, the number of rentable units must increase by N per year in order to maintain Prop 13 tax lock. Seems like very quickly we would have landlords fighting cities to expand their rentable units, expending much more money than they otherwise would in order to expand the rental stock.
Since this is posted here I'll ask a question that has been bugging me for the last year: Who does the captions on these YouTube videos? Is it automated? I ask because every CS193p video starts with the same opening scene/music and the caption describing the music is different on every single one. Is this an auto-caption algorithm just getting it wrong? Or is there a person having fun behind the scenes waiting for someone like me to notice and spend an irrational amount of time wondering what happened? I feel like it has to be a person, right? YouTube's captioning wouldn't give 12 different results.

Edit- For anyone curious, here's how the music is described in the captions at the beginning of each lecture:

1. regal music

2. mellow ambient music

3. light music

4. gentle music

5. air whooshing

6. gentle music (turns out there is one repeat)

7. peaceful music

8. [no description]

9. ethereal music

10. celestial music

11. serene music

12. dramatic music
> It'd be best to just...not drive.

I wish it was that easy of a choice. Pre-COVID, using public transit would have made my daily commute (one-way) between 1.5 and 2 hours, compared to 20-30 minutes by car.

And where I live, we've been paying hundreds-thousands of dollars on each car registration renewal (% of the car's estimated value) for that new transit system, which might not even get used that much post-COVID because of the germophobia that inflicted society.
> Hydroxychloroquine seems to have decent results as well (though with side effects) according to the most recent meta analyses.

From link:

> In conclusion, this meta-analysis clearly shows that HCQ alone is not effective for the treatment of Covid-19 patients and that the combination of HCQ and AZI increases the risk of mortality.

> Failure of HCQ to show viral clearance or clinical benefits with additional adverse effects outweigh its protective effect from radiological progression in non-severe Covid-19 patients.

> HCQ is associated with more total AEs [adverse effects], gastrointestinal AEs, and skin and subcutaneous tissue AEs compared with placebo or no intervention in the overall population

If by decent result you mean "it certainly does something but it's not even clear if it's good or bad", then sure, it's decent.

HCQ is still being studied as it might be useful it some particular scenarios, but its general use is discouraged and understandably so.

I think you are right, this doesn't perfectly fit with existing definitions of other scams. This is more like the beanie baby situation combined with some libertarian political beliefs.
Nouriel Roubini: Bitcoin is not a hedge against tail risk
At a minimal level we want controls (as we do for health care) so that the money doesn't get sucked up by scams.

In the carbon capture area, for instance, there are a large number of schemes that involve activities carried out over a large area of land that all have one thing in common: it's impossible to measure how effective they are.

For instance there is a scheme to crush certain minerals and leave them on beaches, maybe that captures some carbon in the ocean. There are also endless schemes to tie carbon capture to land use (e.g. they told you they wouldn't cut the trees but what will you find if you visit the site 30 years later?)

Contrast that to some scheme where you catch CO2 out of an aniline stripper and inject it into a saline aquifer; you can measure the CO2 going in the way the natural gas company measures CH4 going into your house.

"Unlimnited funds" also scares me because of this: money is a tracer for natural resources. Ecological Engineer Howard Odum (brother of ecologist Eugene Odum) attempted to trace all energy back to the sun:

https://en.wikipedia.org/wiki/Emergy

You can do more detailed work for major energy flows such as a biofuel plant, but at some point you get into the weeds unless you assume the average dollar spent in the economy causes an average amount of environmental impact.

Thus the $6 bottled water that comes in a super-thick bottle and was shipped across the world just can't possibly be sustainable. It's a good starting assumption that something cheap is better for the environment is better than something expensive and then add sustainability considerations on top.

(e.g. if you pay Garth Brooks $50 M in record royalties he puts gas in his pickup truck; pay some lady in Africa $5 for Shea Butter she ground and she puts kerosene in her lamp.)
Uceprotect is enabling people to take down entire ASNs via spoofed masscans
Reposting my perennial comment about solving global warming:

"""

Hence why the real solution has always been:

1. Electrify everything possible

2. Shift all electricity production to renewables, massively increase power output with nuclear nuclear nuclear.

3. Carbon capture.

Bitcoin can be included in "electrify everything", as there are a number of problems with our current financial systems which are very hard to electrify as easily, whereas BTC is electricity-native.
UCEPROTECT is enabling people to take down entire ASNs via spoofed masscans. m247, OvO's major uplink provider just delinked them for scans that are listed in viz.greynoise.io as "easily spoofed". Is masscan now illegal? Or is extortion illegal? hmm
You missed a key reason - batteries are very heavy, and to achieve the kind of range that makes it practical for drivers to switch from ICE requires specifically-designed chassis layout and materials to accomodate battery weight in a suitable location to maintain acceptable weight distribution

With a breakthrough in energy storage technology e.g. solid state, this issue might go away, but right now it compels the production of vehicles specifically designed to be EV and relegates retrofitting to a hobbyist discipline providing relatively disappointing results in range and/or handling.

>Do certificates from Let's Encrypt provide any security benefits over a self-signed certificate?

Depends. The encryption is the same and only dependent on your client/server. Could have been solved by DNS ... maybe.

Self signed certs don't validate that you at least own the domain.
Latencty went through a similar dark age until recently. People would argue that human reaction times are at best around 100ms, but the feedback loop formed by the eyes and ears, through the hands, into the keyboard/mouse/musical instrument, and back out to the ears/eyes, is much more sensitive than that.
Mining is the process by which new blocks of transactions get added to the ledger. There are no transactions if nobody is mining.

When a miner mines a block, they are rewarded with the sum of all fees paid by transactions in the block, plus a subsidy, which is 50 >> height/210000. The subsidy is the process by which the available bitcoin supply is released into the market - a predictable rate which cannot be accelerated. Miners can chose to NOT claim the subsidy if they want, but would be doing so at their own loss.
Going further, if enforcement is separate, I predict hearing from the FBI, "we have enough money to catch polluters or murderers, which do you prefer?" My state (Wisconsin) has largely de-funded enforcement of environmental laws, with predictable effect.
Modules load and eval asynchronously, because there's no viable way for network connected device like a browser to do it synchronously.

But modules still run in depth-first import order, so there is a perfectly fine way do work before other modules run by putting that init code in a separate module and importing it first.

Your second point applies the same to imports and require.

Bitcoin transactions take negligible amounts of electricity to produce and validate. The fact that you can spin up a Bitcoin node on a Raspberry Pi is trivial proof of this.

This is a false choice, clearly.

But regardless, I don't think you're properly accounting for how bad of an externality climate change is, and the (completely unnecessary) CO2 emissions from mining bitcoins is directly linked to a whole future of bad things happening, not just a single bomb.
Yeah (5) is where we are exploring. There's basically a spectrum between groceries and cooking to sitting at a restaurant.

Taste is 'precooked and de-constructed' so all the condiments, and crunchy stuff is separate. Finishing instructions include oven for 3-5 mins and plating. We found this hits the quality vs. effort tradeoffs best for busy people just outside of cities.
The issue with browsers just allowing self-signed certs is that you cant verify their authenticity - ie were they correctly issued for the domain, or is it someone acting as the website using an invalidly issued cert. Having certs come from a recognized certificate authority helps with this because it provides a point for the certificate to be verified for authenticity
It's TB though, per unit.

Canada is receiving so much money for investment because it is perceived as the most stable country in the Americas.

But Canada just doesn't have enough assets to soak all that money up. So that money chases the few assets such as residential property stock.

Canada could legally allow all this money to be invested in startups or companies that need funding instead of passive assets. That way, the same money would be funneled to actual companies and workers, while at the same time, providing assets to all this foreign money.

Do it before America figures this out.
