The previous discussion was talking about adjusting work hours as an alternative to daylight saving time. My comment is that’s not viable a alternative as I don’t think people want to try to determine if the post office closes at 4:00 or 5:00 depending on the date. Additionally, if everyone shifts working hours based on the time of year, how is that different than just changing the clock?

My point is not for or against daylight saving time, just that shifting work hours is not a viable alternative to it. And if we do get rid of changing clocks, there’s a decent chunk of the population that has expressed a preference for permanent daylight saving time rather than standard time.

It’s worth nothing that in Russia they experimented with permanent daylight time some years ago, and at first it was highly supported. However, after some years support for it dropped and they moved to permanent standard time. However, Russia deals with some unique geographical scenarios such as cities with extreme northern latitudes.

The amount of channels doesn't give any indication on the potential users. For example a bitcoin exchange can have one LN channel open with the rest of the network and allow many transactions per second for all its users.
And I believe LN will grow much bigger than VISA, because not only people will make transactions, also programs who will send many micro-transactions to eachother, something which is far from possible with the VISA network.
Actually the alternative is proof-of-stake, which accomplishes the same objectives as Bitcoin with very little energy consumption.

In my experience, the biggest problem with the Java SecurityManager approach is that it's thought of as too difficult to understand / cumbersome to configure (and I'm not saying this belief is wrong), and so most apps either run with no SecurityManager explicitly configured or configure things the "simplest possible way" which usually winds up being approximately equivalent to "anybody can do anything".
You don't need a virtualenv. You can simply launch python with the PYTHONPATH environment variable (there are also other ways).
Look at the distribution of Bitcoin. Do you think it's any different? A small number of people (I'm excluding the exchanges here) controll the majority of the bitcoins.

> destroying 50% of the value of that cash

If this scenario were to actually play out, a huge number of people 'hodling' bitcoin will cash out. I guarantee it. I wonder what it will be worth after that sell-off surge?
Then you might as well price in the cost of the computers and GPUs assembly into Bitcoin's cost. I don't see the utility in going down this chain of production.
The WASM ecosystem is exploring this through the use of what they call "nanoprocesses" wherein libraries are wrapped into modules and provided access to nothing by default [1]. This seems to be more of a pattern and consequence of how WASM works than a specific feature.

> it has the usability of an IRS form and never gained as much popularity in the Java world than npm in the JavaScript one for that reason.

I thought IRS forms were hard?

I have more than a decade of experience collected from work with CDs (Delphi), downloaded libraries (Delphi, Java, PHP), Ant (Java), Maven (Java), PEAR (PHP), Composer (PHP), Nuget (.Net), NPM/Yarn (Javascript/TypeScript) and Gradle (Java/Kotlin).

Two of these have been somewhat easy to work with for as long as I used them: Maven and Yarn. I hear NPM us usable now, but it absolutely wasn't good early on.

> “we are getting .jar files individually and not using maven because it's a [...] mess”

It seems obvious from your writing that you either worked in a place that was really serious about security or had no clue. Both could result in this conclusion, but based on your writing my bet is on the latter, i.e. they were clueless.

Edit:

Reading your comment here: https://news.ycombinator.com/item?id=26091480

I have concluded that it was a mix of those two: the people you worked for were trying really hard to be really serious about security and failing to automate it.
GP's point is about the tradeoff that switching to electric cars versus ICE provides, and BTC does not.

Let's assume that switching to electric does not, itself, cause an increase in total cars on the road. Let's also assume that both ICE and electric vehicles require roughly equal amounts of energy to travel equivalent distances (this is probably not true, but helps in the analysis). The tradeoff between an ICE or electric vehicle, then, is which produces more carbon emissions for the same amount of energy: the gas/diesel combustion engine or the power plant?

If the plant is more efficient, converting to electric vehicles will produce a net reduction globally, but a net increase locally (at the power plant) in carbon emissions.

If it's equal, then we just shift the source of emissions to the power plants.

If plant is less efficient, then there will be a global increase. This is the worst case, it's also not the likely case.

This gets improved later with the ability to switch to cleaner energy production methods than burning oil, coal, or natural gas. This is not an option if we remain with ICE vehicles, we can't put a wind turbine on them or a nuclear reactor.

BTC doesn't trade anything, it just increases energy consumption (and therefore production). In the near term, at least, BTC will increase carbon emissions because that's how most energy is produced. Not just exchange the location of emissions. BTC isn't replacing oil burning bank ledgers. It's just consuming orders of magnitude more energy to do a similar job.
> The US ha certainly invaded multiple countries ostensibly for control of their oil.

No it has not. The "multiple countries" of which you likely refer to is in fact two: Iraq and Libya, and the declared reason in neither case involved oil. The US went to war against Iraq ostensibly because of Saddam's WMD programs (which were only later conclusively found not to exist), and the intervention in Libya was at the bequest of the United Nations following the popular revolt and civil war against Muammar Qaddafi, itself largely deriving from similar uprests started after a Tunisian set himself on fire and improbably drove the Tunisian dictator on the exile.

In neither case was control of oil a declared reason. And in neither case has control of oil ever been clearly demonstrated to be an actual reason for going to war.

Off topic, but looking at the curriculum of the course and the more I read about native development, the more I love Flutter. There are so many barriers to entry for native development, to develop and publish a simple app is such a complex procedure that I respect anyone even trying to go Native first without any prior knowledge.

Flutter on the other hand, is a pure joy. Almost anything you need UI-wise is prepared, and you can just customize it the way you want (try implementing a ListView in native vs Flutter). For the big majority of today's apps native is just not neccessary, most apps don't need bluetooth access or some other specific service.

Especially from the business side, Flutter is way better. You need to maintain only one codebase which results in less need for resources. And you are way faster, you can iterate like crazy and push out an MVP...

And when stable Flutter Web arrived, it is game over...

Why? If I want to send money to Bob in Venezuela I need a connection to him. And I'm not interested in sending further transactions to him. And he is in Venezuela and cannot rely on institutions (this is the real scenario that advocates keep bringing up). How am I going to pull this off without an on-chain transaction?
There’s so many things wrong with this comment.

Until people start accepting bitcoin for bread, rent and salaries, Tesla most certainly does not have a “stash of money that cannot be forcibly shut down”. It has something that might be able to be exchanged into a local currency to buy those things.

What’s more, that stash of bitcoin most certainly could be forcibly shut down at the stroke of a pen. Tesla is a public US company listed on a US stock exchange. If the USA decided tomorrow to criminalise BTC, Tesla would be left with a huge 1.5bn hole in its accounts and a huge number of very pissed off investors.

Moreover, if Elbonia doesn’t want Tesla there, how in the hell are Tesla cars going to arrive at ports? How are they going to be registered? How are Tesla going to deploy charging infrastructure? BTC has exactly squat to offer in terms of dealing with jurisdictions that don’t want them there.

BTC isn’t some magic wand that lets you operate in a fairy dimension where none of the rules of reality apply.

Why though?

Yes, you are not controlling for the amount of coffee consumed. But that should cancel out in a population based study. The null hypothesis should be that humans drink coffee in a gaussian distributed way (not like with alcohol where the consumption is exponentially distributed). If you then randomly sample from that coffee drinker population (again, gaussian distributed), you can then control for variations in the coffee consumption by comparing the averages of coffee drinkers to non-drinkers.

But, yes, this does center around the hypothesis that coffee consumption is normally distributed. To confirm that I'd assume that there has been some research done on coffee consumption. Research that I have not done, to be clear. But I with no priors, I'd assume a normal distribution, because, well, darn near everything in bio is normally distributed.

So some big limitations, speaking as a doctor. Firstly, I'm surprised that they allowed watches on the ward. They're a huge infection risk and most places are bare below the elbows (NHS), moreso for covid. Secondly, they only looked at symptomatic covid cases (1 day before symptoms started was their prediction as far as i can tell. This is completely useless as the 24hrs before symptoms start the patient is likely to already be highly infectious, and misses the asymptomatic carriers which have an indeterminate effect on spread as well. Far better to use the semi-proven (but equally controversial) lateral flow tests and avoid these risks. In the UK, hundreds of healthcare staff have been identified as covid+ >48hrs before symptoms in this way.
We compete. But Tock started as a reservations platform and shifted to delivery. We think nice dinners at home is a pretty different category so the solution may look very different - for example we have a Dining Notes feature that hosts playlists, finishing instructions, and plating photos.

Another core difference is we handle the customer support and offer the Taste Guarantee. Diners really love this because the experiences are higher priced so they want high touch service as well.

As the category expands we think there will be more and more nuanced but critical differences.

Man, what koolaid. Bitcoin is a speculation market that has done nothing but benefit rich speculators and its computational demand has led to vast negative externalities for the planet. Stop doing that!

Maybe you should support a bloodless revolution by volunteering at a soup kitchen.
> including the externalities from the extraction of oil, which implicitly backs the dollar

This isn't true. Internationally the thing that backs the dollar is the U.S. economy. People know they can spend dollars to get anything they need. Domestically what drives the dollar is that it's the only way you can pay taxes.

I suppose you could say that oil is used to defend the U.S. economy but that's a stretch.

Super pessimistic. I don't know why this comment is at the top. The analogy and calculations are fun, but nothing more than that. You are basically suggesting that we all should buy Teslas, right? 330 miles roundtrip is about 5-6 hours of non-stop driving. Not the best UX.

I do international transfers quite often. Every time I try to send a more or less large amount, it becomes a pain in the ass both for sender and recipient. You have to prove that you are not a unicorn.

People use Bitcoin because it's freedom from the existing banking system, plain and simple. When you are sending money via a bank, it's like someone is watching you at a bathroom. It simply doesn't happen with Bitcoin.

Bitcoin will be the force that will make all the miners completely switch to a green energy (and that's already happening).

People would only mine on the shorter blockchain if they think it's valid and good luck adding a country firewall in an undetected fashion. It will be directly visible in one of the two forked blockchain that a lot of the hashpower has vanished.

If a country is behind a firewall, most likely, almost no new blocks will be mined because the hashrate difficulty will stay constant while the computational power behind the firewall will become too low. Blocks will be mined much more slowly for a period of time inversely proportional to the hashpower behind the firewall. Most likely, that chain will enter into a "mining death spiral".

According to a relative who's worked in the industry most of his life, the carbon footprint just from manufacturing and disposing of batteries for electric vehicles is not compensated by the decreased emissions. I think the lifetime is ~5 years shorter than the "carbon neutral time" of using a battery over conventional fuel. Much of the research now is to either reduce the carbon footprint of battery manufacture, or to increase the lifetime of the battery to compensate, but the batteries themselves are apparently worse for the environment than the engines they're replacing.
They want to increase energy consumption so there's more need for electricity so they can sell batteries to bitcoin owners? [lol]
I'm one of these holders who hold to avoid cash depreciation, I don't plan on ever selling a single satoshi. Now you might ask, what's the point then, are you not gonna spend it at all? With many new defi projects, I can unlock my Bitcoin's value and use it without ever selling it.

Many holders have similar ideological beliefs, Michael Saylor also said he doesn't plan on selling any and that he would just borrow against it if he needed the cash.
Are you dead set in your ways or are you open minded enough to be willing to research a few different perspectives. Please at least research a few more opinions on the term by both groups okay and opposed to it.

It's a good point and I'd love to see an analysis of how much electricity an average bank uses or a country's payment system uses. But until now I haven't seen one.

I think another point to note is that Bitcoin (and Crypto/DeFi in general) is really just a censorship resistant Casino, and I say this having worked in blockchain and crypto for the last 6 years. As such, the massive electricity usage is all the more egregious.

On the other hand. Banks actually add a lot of value whether we care to admit it or not. They provide a working payment network. They provide credit when you need it etc. Yes, the banking infrastructure probably uses a lot of electricity too - somehow those mainframes need to be powered but I'd like to think we can all agree that society benefits from this. Where as, with Bitcoin, only a small few benefit but the cost of running the infrastructure is so high.

Maybe a better comparison is how much energy the gold industry uses vs bitcoin mining?
2700 transactions for 10 minutes comes at 4.5 per second. So yeah, matches.

> Your statement is entirely unclear. Could you restate it? For Steelman purposes, I'll ignore the non-sequitur about cheating.

By cheating I meant making a sidechain that would become longer than the mainchain, thus enabling a double spending attack. If the amount of money to be made in double spending attack is higher than honest mining someone will make it, the only thing protecting against that is that the cost of mining must be large enough compared to value being transferred.

>I'm not sure what you mean. In general, energy costs seem to be dropping over time

Back when it was CPU mined. Before even the first GPU mining. It was just about proving that you have an actual HW dedicated into the task.

Exactly as mentioned in the quote that you said. He didn't have a clue that it would become dedicated HW that has only a single function, burning energy to calculate SHA256 and nothing more.

Also do note that the whole concept of non mining node was foreign. Instead of the original design of nodes that mine we're in situation where nodes don't mine and most mining happens in centralized farms.
Just to clarify - it seems that your first comment says that "it's crazy to call excess consumption green, even if your excess consumption uses clean energy", and your second comment says that "it's crazy that we allow excess consumption in the first place"?
You nailed it wow. Didn’t even think to check there.

You vastly underestimate the level of bureaucracy that can exist in the biggest Java users of this planet (namely banks and public administrations): in these organization (at least a few years ago, the Solarwind attack shows it may not be the case anymore) every single dependency you want to use must be justified, and then is audited by a dedicated team, which ends up handing you the validated .jar.
