So, pass laws requiring crypto mining to use 100% renewable energy? Sounds like a win-win to me -- no greenhouse gases from crypto mining, and lots of investment opportunities for high-power green tech.
I remember a time when you didn't even know who was President if you weren't paying attention.
If I’m understanding you it something I need. Friend of mine and I always share links with one another across various platforms and can’t ever find and old link or comment specifically on a link. Especially on different timezones.
i highly doubt any of those 3 examples use enough energy to be meaningfully measured as a percentage of the total global energy consumption
It very much seems like they do, doesn't it?
If you are suggesting to make inference from a single data point, you kind of proving the necessity of peer review.
It depends. Only if your (resistive-pump) cost difference is lower than your Bitcoin gains. That will depend on your geographical location though and the current BTC price.

Did you ask? Like, honest to god talk to people about how they feel about the website - not just rely on deep telemetry that mostly serves to let people lie to themselves and whitewash doing whatever they want to do as being "data-driven".

A big problem with modern technology is that the feedback from users does not reach the vendors.
While that's plausible, I'd still agree with the parent comment in general -- it's true that it's not cost-effective to mine using fossil fuels (you would lose money doing it), and this alone requires a different way of talking about the issue.
Safari 14 added WebExtensions support, so where are the extensions?
This analysis assumes miners use a selection of currently available mining rigs.

I think we should consider the fact that many of the biggest miners might have access to unreleased mining hardware which performs substantially better in terms of $/watt.

If they did, they would make massive profits. If they sold their more efficient mining hardware to the general public, the lost profits would far outweigh the money earned by selling more efficient mining hardware.
Which county are you in? I’ve never had a lack of convenience from normal banking.
Sounds better than the ending of the interglacial period we are currently in within a ice age. Let's hope mean revision is not dogma.
Have been with one of the very active communities in Seattle. Very happy with it. Really amazing to reuse products and not let them go to the trash.
Maybe it's just because people care about the future of our planet and don't care about those crypto-stuff?
I don't understand why everyone is arguing about whether their CO2 emissions are less than from some other source, when the whole point is we need to be carbon neutral within the next 15 years.

Average CO2 emissions per US Citizen as of 2018 is 16.6 tonnes. Go buy your carbon offsets while they're cheap - less than $9/tonne over at cooleffects.org, which is what I used yesterday.
Moore's law was (1) an observation of historical data and (2) never a guarantee by vendors to make higher capacity products at lower prices. The extrapolation is just nonsense wishful thinking.
While the COVID-19 pandemic has struck hard in some countries, it has not been on a scale which threatens humanity in any form? Excess deaths for 2020 are in the ranges 10-300 per 100k, meaning under 0.3% in the worst case.

Not that pandemics cannot be properly devastating. During the bubonic plague up to 50% of the population died in many areas across the world. It was still no threat to humanity though.
You're wrong. What they want literally makes the MBP not usable for many others, whereas what I (and many others) want doesn't affect the usability/performance of the MBP for anyone.

> it's that Emacs on windows is terrible.

I use Emacs on Linux and Windows equally. I've used Emacs on Windows at work for a decade. Other than magit, there's virtually no difference in experience between the two platforms.[1] Of course, perhaps you use a different set of features than I do.

> Maintaining Emacs on windows takes considerable effort.

I install it on my work laptop every 2-3 years, and for the last 5 or so years, it's literally been "Download, unzip and run." Occasionally I have to make registry changes to get org-protocol to work. Even 10 years ago, it was still fairly simple - just a bit of extra work to get some GTK related stuff installed as well. But right now it couldn't be easier.[2]

And I don't even use WSL. This is native Windows.

[1] Of course, if your Emacs is calling out to tools like grep/find, etc, you'll have issues unless you install those tools. Although these days, it's not hard to configure it to use ripgrep and fd, which has excellent Windows support.

[2] And perhaps installing LaTeX if you want to export org files to PDF.
Note that three articles were published in response to this one (linked as 'Matters Arising' in the top part of the article), and they all appear to criticize the methodology that was used here.

The key objections from the first such article [1] are as follows (quoted verbatim, though the article itself obviously contains more details):

> First, the use of transactions as the driver of future Bitcoin emissions is questionable, given the tenuous correlation between transactions and mining energy use...

> Second, all three Bitcoin adoption scenarios designed by Mora et al. represent sudden and improbable departures from historical trends in Bitcoin transactions...

> Third, Mora et al. applied outdated values for mining rig efficiencies and electric power CO2 intensities, which inflated their estimated 2017 Bitcoin energy use and CO2 emissions values considerably.

> Fourth, by analytical design, Mora et al. applied 2017 per-transaction energy use and CO2 emissions values in all future years, multiplied by annual transactions... This decision effectively held both mining rig efficiency and grid CO2 intensities constant for the next 100 yr... This unprecedented choice ignores the dynamic nature of mining rig and power grid technologies and violates the widely followed practice of accounting for technological change in forward-looking energy technology scenarios...

> Fifth, in constructing their scenarios, Mora et al. committed key errors when analysing adoption rates within their 40-technology comparison pool...

> Because in 10 years nothing you built today that depends on JS for the content will be available, visible, or archived anywhere on the web.

What? That doesn't even make sense. Javascript and browser vendors are going out of their way to be backwards compatible (to the point of rejecting the perfect Array.prototype.flatten in favor of the ungrammatical Array.prototype.flat so as not to break websites that depend on MooTools). Is the author implying that in 10 years the javascript of today will no longer be executable by the browsers? Why?
Apple does sell an ad product, although I'm not sure whether it has any presence on the web.
The comparison would be for locally produced solar. We know that making solar panels on Earth is a net positive energy expenditure, from raw materials to recycle/disposal, and just barely so. But the cost of creation of solar panels on Mars is unknown relative to net energy expenditure. I'm fairly certain that it would be many decades, if not centuries, before it became net positive. Sending solar panels to Mars is obviously not a good use of Watts.
Assuming this forum has enough clout to swing the price of BTC is probably a bit of an overstatement...
Aren't we already well past the co2 needed for a 2C rise? And still accelerating...

Edit: yes, even if we cut emissions drastically, the existing 450ppm CO2 level would be enough to get us 2 degrees.
Wait, you can short Bitcoin now?

I love that bitcoin maximalists have now become the ire of the global warming movement. Quite fitting as it literally is the ponzi scheme of our generation helping criminals launder their money. History will not be kind to those who pushed shitcoins, I personally would never ever hire someone who've been associated with such outfit.
It's no gold :D Just bits.
How much energy is moral to use in pursuit of “sound” money? Maybe Bitcoin hasn’t crossed the threshold yet. But I disagree that we should completely sidestep that conversation.

FTFY

There is zero actual evidence of anyone communicating with any non-human intelligences.
Thanks for educating me on this! It is super interesting that there is a formal theory behind it.
Some of them did only consider weight. It is the conclusion of the meta itself a mean BMI couldn't be determined from the 12/17 that had it. I don't think those running the studies are at all dumb. They are often focused on specific things, and to the exclusion of generalizable conclusions. I do find it odd that even mean BMI wasn't of apparent interest in diet studies, but I haven't gone thru each sub-study to see why or why not.

I wouldn't feel comfortable reading too much into this one's conclusion. "Low-carb w/o any additional specificity looks like bad news" seems technically fair to me, but actual diets are going to tend to distinguish fat and protein as well as their sources so that isn't a a very logical stopping point for an actual decision. Including core concerns like fat vs protein and plant vs animal sources can yield different conclusions, as the meta linked in the sub-thread above did.
I'm a dual citizen - my family lost their savings in Lebanon because of banking capital controls. That story is not unique to our generation or history more generally.
I used to use an open source ray tracer called POV-Ray in the early nineties and it was pretty impressive. Here’s an example of an early scene you could render with it: https://amp.reddit.com/r/vintagecgi/comments/eswamt/chesspov...
The scarcity of bitcoins depends on the scarcity of computational power, and at scale that causes all the problems associated with generating energy. But is that the only viable way to generate scarce tokens?

What if there was some objective, necessarily incorruptible and public source of random data, and tokens were generated only when certain values appear? The number generated is adjusted by adjusting the range of those values.

Is such a publicly verifiable random source possible? Some kind of cosmic slot machine, like maybe variations in a pulsar? If it is possible, could it actually be a low power way to mint scarce tokens?

The same random source used to generate the tokens could also be used to randomly distribute them. Is that compatible with the incentive structure of crypto coins?
Ok, yeah that was what I recalled too. Although that does not diminish the coolness of rclone, and I will have other use-cases that requires its use. I just need a bidirectional synch for my linux machines. Thanks!
The thing you did not noticed is that article is in English. The "When the Isaevas moved" is perfectly ok English sentence.

If you're in Venezuela, Argentina, Lebanon, Turkey, Nigeria, etc. where your government is stealing your savings via massive inflation it's pretty useful.

It would definitely be better if the learning curve was shallower and the UI's easier, so that more people could be saved.
I agree the absolute pitch that orchestras played at may not have been consistent like it is today. However, perfect pitch is not really about Western standards or whether A equals 440. It's the ability to remember a pitch in absolute terms.

As a musician, I have a finely-tuned sense of relative pitch. I can pick out chords and melodies easily, but I don't know the reference key unless I hear an instrument and I'm told what note it is playing.

My son has perfect pitch. This became apparent when we watched the movie "A Hard Day's Night", and he complained that it was out of tune with respect to the Beatles albums he had heard.

I listened carefully to the two sources, and it turned out the movie was about a quarter tone flat compared to the recordings. Only a person with perfect pitch would notice that. The rest of us forget the absolute value of a pitch in a matter of minutes or less.
Well there haven’t really been any competing technologies either. Maybe tcl nxtpaper will push eink forward. Or ultimately kill it
Its difficult to find the details on this because these companies are so secretive, but from everything I have seen, the e paper technology we have is completely useless for anything but displaying mostly static content. The refresh time is insanely slow so simply typing text or scrolling a page would be almost impossible.

Also almost all of the full color eink screens I have been able to find details on are actually just normal TFT LCD displays with some matte film over the top. The core eink tech seems to be fairly easily changed to get 3 colours at the cost of 15 second refresh times but any more colurs seems unlikely.
> People use it to pay for games, buy things, sell things, donate and preserve the value of money earned in depreciating fiat.

This is where the argument about energy usage per transaction comes in, namely that Bitcoin is terribly, terribly inefficient at providing this value. From the OP:

> A single bitcoin transaction alone consumes 621 KWh, or half a million times more energy consumption than a credit card payment.
Segregated Witness (SegWit) was activated in July 2017. https://en.wikipedia.org/wiki/SegWit And overlays like the Lightning network have been in use for even less time.

It’s super impressive that someone can just look at a die image and know what blocks are what. Kinda wished I knew more to about ASICs to be able to do the same.
>when you switch devices

Signal requires and only supports a single mobile device, you can link multiple desktop clients to a mobile device. But one cannot have signal on multiple devices.
A lot of people I knew that used WhatsApp used it because international text used to be prohibitively expensive and it was notoriously unreliable. So most of my friends used it in Europe. Also you can still use it if you aren't on cellular while traveling. Although I'm sure the cross-platform, freeness, and reliability were all pluses.
Electricity is fungible, attached to a grid, and we aren't at 100% renewable.

So unless the miners are going out of their way to build their own solar capacity (they aren't), it's all essentially carbon.
Worked for a company like this in the first dot-com boom. VC funded. Spending money like mad. Lavish offices. Big sales staff. Top-of-the-line Sun servers and Cisco networking gear. It was all focused on being ready to scale. Never had one paying customer. When the last funding round didn't materialize, the burn rate killed them in a matter of weeks.
No it doesn't. My MBP can't handle a 27 inch external monitor without putting so much pressure on the CPU. If it had a dedicated GPU, that would take care of video output and not make the mac drain its battery by having the CPU fans at +6500 RPM all the time.
If it was all abundant wind-power, sure.

Denmark, famous for its wind farms and for having too much renewable energy at times, only has 6.1GW of wind capacity, which is is a few gigawatt short for the Bitcoin network.

So no, there isn't an abundance of energy when you decide to throw it all away as fast as you can.
I can't find a single factual statement in Stephen's tweet thread I disagree with. Your use of subjective pejoratives rather than specifics seems to imply that you are the same position.

"X exists on Parler" and "Parler's moderators were fine with X" are completely different statements and the first does not imply the second.

To make such a claim, I assume you have a quote or Like (whatever the Parler equivalent was) from a moderator supporting it. Care to share it?
> It is unlikely that a GPU is an efficient heat source.

This is plain wrong. A device that consumes N watts of power (and doesn't output electricity or some other form of energy) will eventually produce N joules of heat per second.
Good for you. Sounds a lot like what getaloecare.com is doing in their app.

Pleiades myth of the sisters come from Babylonian star catalogues: https://en.m.wikipedia.org/wiki/Babylonian_star_catalogues

[..] Babylonian astronomy collated earlier observations and divinations into sets of Babylonian star catalogues, during and after the Kassite rule over Babylonia. These star catalogues, written in cuneiform script, contained lists of constellations, individual stars, and planets. The constellations were probably collected from various other sources. The earliest catalogue, Three Stars Each, mentions stars of Akkad, of Amurru, of Elam and others. Various sources have theorized a Sumerian origin for these Babylonian constellations, but an Elamite origin has also been proposed.[..]

MUL is ‘three stars each’ and Pleiades was a cluster of stars which is ‘star of stars’. MUL.MUL. While star was depicted as three star(looks like three asterisks), Pleiades was represented as twice that.. two MULs or six stars.

This could be the reason why Pleiades was depicted as six stars even though the cluster has more than 6. Everything came to us from Sumerians tho’

On Sumerian constellations and star names:

Correct. It's FOSS. But for companies it is OSS.

In other words, it's free software. But for big companies not free as in beer.

Perhaps you should explain your objections against big companies paying for open-source software? That would be more helpful than focusing on whether it's called free or not, or on how organizations defined things in the past.

GPL isn't always adequate because some OSS authors might want their software to help entrepreneurs bootstrap their businesses.

China already built 2 of the longest transmission lines in the world (~2000km), so location doesn't seem a huge issue. The question is - is the extra energy not being transported because there's an existing use for it (btc), or would it be generated and not used anyway. Or would the power plants just get shut down otherwise?
In the past I always just used the "free stuff" section on Craigslist both to give things away and to pick up some great things.

Heating with electricity is pretty expensive / inefficient.

People don’t vote with their time and energy, they often vote with their wallet regardless of the impact on energy and the environment which is the issue. See: Negative Externalities.

The problem with Bitcoin is that energy waste is inherent in its design. As Bitcoin value goes up, the value of a Bitcoin relative to energy changes, which encourages more mining, which results in higher energy spend and emissions as the algorithm difficulty adjusts to the new hash rate.

Generating 10,000,000 bitcoins could be done at low energy with a few miners - but the more valuable they become the more energy they use.

My issue with Bitcoin is that while other industries try to save power, Bitcoin tries to waste it and waste is built into the algorithm.

And the more popular Bitcoin gets, the more our planet gets polluted trying to make magic numbers on a ledger.

The US has 3.9 in the Human Rights category. It is shared with these countries:

Albania, Chile, Ecuador, Poland, Seychelles, South Africa.

"Factionalized elites" is common to Jordan, Malaysia, Eswatini and Congo Republic. The best position is #13 in Public services, between South Korea and Austria. Bottom five (IE. the best five) are Finland, Norway, Switzerland, Denmark, Iceland. The US is at a total #30 from the bottom (again, worst is best) right after UK, UAE and Slovak Republic. Quite telling and seems to fit perfectly fine IMO.

Thanks for the links. I memorised a number of decorative knots as a kid, but it never really occurred to me then that they were formed of smaller parts. That didn’t seem to be necessary at the time. Also, you do have prime knots, which are not decomposable in a certain way.
10-12L is too small. Get a 20 or a 40L, use aqua soil instead of all gravel, heavily plant it, work less. I prefer to keep shrimp, boraras some otos and one or two clithon snails (one per 20L).
