This thing is gonna get flooded
Is there any evidence that cryptocurrency actually had a significant impact on real CO2 emissions? The idea that raising energy usage somewhere commensurately increases emissions based on the "energy mix" that predated that extra usage is an oversimplification.

Most of the mining happening in China, for instance, is happening near non-CO2 emitting plants (hydropower, wind) where energy is virtually free most of the time. The increased demand for energy that is otherwise of little value may in fact be financing a rollout for renewable energy. The primary problem with renewables like wind power today is not production capacity, it is storage.

It stands to reason that at least some mining temporarily leads to increased CO2 emissions due to revenue exceeding the cost of fossil fuels. However, this only happens in the short term, because of difficulty adjusting revenue to the point where only the very cheapest energy sources remain competitive, and these are not fossil fuels. Furthermore, the increased demand for more efficient semiconductors finances the R&D required to lower the power usage of all computing into the indefinite future.

”The utility of a term of art for any piece of software that includes two of the most common concepts in computer science (hashing, linked data structures) is just bad classification. This includes such a vast category of software to make the term meaningless...”

”For the last 10 years a whole cottage industry has arisen trying answer the question: Is blockchain useful for anything but gambling? After about $30b in sunk investment and a 0% success rate the industry finally has the answer: NO”

On the contrary, DLT, or distributed ledger technology, is a new kind of primitive and extraordinarily useful.

I think this is said to express "simply replacing that function call/method/... without changing your calls/methods/coding style is not going to magically solve your problems". Which is true in the push_back/emplace_back case (you need to adjust your call).

Propaganda at it's best (he refused outright, yet visited Samsung...just to have a look): "Morris Chang was now struggling to get sales/orders, but he was tired of being second and third, and he firmly refused Samsung. Lee Kun-hee did not give up, and invited him to visit Samsung. Morris Chang readily accepted, and after visiting the factory for half a day, he even praised Samsung's production capacity as "impressive", but still refused to leave TSMC. Seeing his firm attitude, Lee Kun-hee had to give up."

I think what you wrote largely applies to Java and especially JavaScript, much less to C#. Value types, real generics, and native stack allow even the faster version of the .NET JIT to produce native code that’s not too horrible performance wise.

Good enough for desktop or embedded use cases, even on slow CPUs. I have 3 such devices on my desk, Raspberry Pi 4, a dev.board with Rockchip RK3288, and a tablet with Atom Z3735G, .NET is reasonably fast on all of them, without noticeable warmup issues at startup.
Alice has a malicious Chrome extension which steals cookies and secret keys... Now all of her messages, and chat messages from her friends, and groups she's part of, have all messages intercepted, and all historic messages leaked.

Video chat is expected to be emphererial by users, and having a malicious chrome extensions steal it breaks those expectations.

It's hard because desktop as a platform has far fewer security guarantees, and a user isn't just putting their own data at risk, but that of their friends and contacts too. Facebook has been burned by pretty much the same with Cambridge Analytica.

The post addresses this question in detail. In brief summary, extracting "green" energy from the grid (most mining occurs on the grid) means that the energy available on the grid is more likely to be from CO2-generating sources. The amount of demand for that grid power is partially non-negotiable (things like street lamps, life support equipment in hospitals, etc) and partially negotiable (if the cost goes up enough people might stop using tv or indoor lighting, I guess?), but ultimately if demand spikes there will just be more coal and gas getting burned to provide power on the grid.

Also, the green power generation requires the manufacturing and distribution of things like solar panels, which is not currently CO2-neutral and has other environmental impacts.

There are also theoretical (if not real) limits to how much you can actually expand grid capacity. Mining already even in conservative estimates consumes a lot of power, and unless PoS is fully rolled out it will continue to consume more and more, which will put increasing strain on local power grids.
There's a "review queue" of games where you see user feedback and you decide whether to allow the game on the list or deny it, along with a reason why. It's an allow/deny system, basically, except sometimes you have to look at the games to try and tell if they should make the list or not.

> Digital files don’t have that much going for them. They store monumentally less information than say, a piece of paper- which contains the artwork on it as well as inscribed histories of hand, pen, ink, pulp, forest- a dense connected materiality that unfolds forever. A digital file is a pauper in comparison. A file breaks down to requisite ones and zeros well before one can reach the atomic composition of the materials in a physical drawing.

> Digital files also require power to access and maintain, and are incredibly unstable over time as new operating systems, plugins and standards render things unviewable- often within a decade. They are also vulnerable to bitrot and physical degradation of storage media- the stable shelf life of a CD-ROM, for instance, is less than 20 years.

This is pretty much nonsense. The actual artwork on a piece of paper will typically be lower fidelity than a digital version of it, and paper degrades faster than CD-roms. I've dug out a CD full of photos that spent 10 years in a damp attic, and the photos are as good as the day they were taken - try that with photos printed on physical paper. Furthemore, while an NFT is by design not copyable in some sense, it's certainly not vulnerable to degradation of physical media.

Good points. My main problem is the butt-clenching costs of FIVE Hue bulbs. I have contemplated using a splitter with 2 60W bulbs in a lamp next to my bed though.

Although I checked again recently, and they now sell them with Bluetooth direct, eliminating the cost of the Hub (with limited functionality, but enough for sunrise alarm clock, I think). Still puts you solidly in the 3 fig cost territory...

C has other use cases. Reverse engineering and Exploit Development, for example.

I like this crypto UBI idea! But without the early movers incentive to increase the coin value, how could that work?

"Any criticisms of Trump are bad faith smears by the Deep State defending the status quo."

Hmm.
The article addresses this. In summary: both things are bad, but it would be nice to not make them worse. Expanding the power spent mining crypto makes them worse, with how things are right now at least.

Also, NFTs are generally based on Ethereum, not Bitcoin. Did you read the article?

Transistors change their effective resistance based on the "control stimulus", which in turn changes how much current can pass through them.

In BJT transistors the "control stimulus" is the current flowing through the base pin, while for (MOS)FET transistors it's a voltage potential between the gate and source pins.

The amplification happens because in the right region the change in effective resistance is high for small variations in the "control stimulus".

If you drive a BJT with a resistor in front of the base pin, you can drive it with a voltage. If you put a resistor between the gate and source pins, you can drive a MOSFET with a current source.

So the way you control them is different, but what they end up doing is the same. And by using a resistor you can effectively change the way you drive them.
Already started to happen. People have been posting complaints about junk or low-effort NFTs on Twitter a lot recently.

And I'm sitting on Marcel Duchamp's toilet chuckling to myself.

Thank you for the laugh this morning.
I think until NFTs can actually be minted and distributed via PoS, PoS doesn't matter. It's been "coming soon" for ages. I eagerly await Ethereum's transition to PoS but today when you sell crypto art it's PoW.
Slightly off-topic, or perhaps more general.

The solution to proof of work using too much energy is not proof of work. It's fractional reserve bitcoins / ethereum / etc.

To explain:

For game theoretic / economic reasons, people will spend as much effort mining as there are mining rewards to be claimed.

If move to a system that doesn't hand out mining rewards, you still have to hand out the coins on some basis. So people will do the activity of that basis as much as there are rewards.

I will talk about bitcoin for simplicity.

It behaves very much like gold in a lot of respects.

If bitcoin sees wider adoption as cash, that means it will have to support a larger amount of spending in real terms and also a larger demand for real balances held in 'cash'.

Since the total nominal amount of bitcoins is fixed, you can only get the latter via an increase in the real value of each bitcoin.

But, here's the solution: gold was (and is) also hard to mine, but even when gold was money, you didn't actually need physical gold coins to serve most of your cash needs.

Bank notes and 'checkable' deposits fill this very need: they allow to expand the effective money supply without needing to mine more gold. The same will work for bitcoin.

(Of course, only that the banknotes will be electronic, of course.)

We already see some signs of that eg in bitcoin futures. The only way to get investment exposure to bitcoin used to be buying physical bitcoins. But nowadays you can buy (and roll over) bitcoin futures instead.

Of course, every future needs a counter party that's taking the opposite side of that exposure.

If you think about it, that's pretty much the same thing that banks do. Selling futures is very similar to offering time deposits:

With a time deposit, the bank incurs an obligation to pay a certain amount of money later. They could hedge that obligation by just holding on to physical money, but more typically, they invest in assets like bonds and loans, and hope to be able to exchange them for money when they have to pay back the time deposit.

That's basically the same economic exposure as being short a bitcoin future and going long a bond future.

To end the long rant, even if your base currency is gold or bitcoin, you can support lots more money than that.

> The problem with crying wolf is that,

India is one of the most corrupt countries in the world so people complaining is not exactly crying wolf.
> There is no reason for that. A more solid/reliable machine doesn't have to be more expensive. Using better materials may cost up to 20% more i believe, but will certainly not cost several times the price of the reference (faulty) product.

Source? I have a hard time believing that there exists the ability to sell a longer lasting product at a sufficiently low price, and yet no business is taking advantage of this to steal business from the incumbents.

> Also it's important to note planned obsolescence is usually not even the result of bad materials, but conscious sabotage. For example, placing capacitors near a source of heat (looking at you TV manufacturers).

I don’t know about this. I’ve always bought mid to higher end TVs and they have never died on me. The commercial ones I buy for hotels also come with 5 year warranties, and over 10+ years of LCD/LED TVs I can’t recall a single one that simply died. My electronics seem to be lasting longer and longer, but I also don’t buy the lowest price products.

> That's not entirely true. The few that did had to stop because unfair competition (using poor labor/environmental regulations) were driving the prices down.

Yes, but that’s the world we live in. As I wrote, the solution to this is increasing taxes on fossil fuels and other sources of pollution and imports from countries with lax environmental and labor regulations.

> Many people will if the arguments are exposed in a reasonable manner. Durable products with available spare parts are considerably cheaper in the long run: a washing machine that lasts 60y for 2000$ (plus maybe 200$ of repairs over the years) is more viable than buying a 500$ machine every five years (2200$ vs 6000$). And that's assuming hardware even lasts 5y, which in many cases it does not.

How are you projecting labor costs over 60 years? In my adult life of 15 years, labor costs for anything remotely skilled have double, and I don’t expect to pay anything less than $100/hour today. And I don’t know anyone who is replacing hardware every 5 years. It just doesn’t jive with my experiences that all these appliances people have are breaking down so often in 5 years.

And I do not think that the people buying cheap products today are doing so because they don’t have the information. People buy cheap garbage because they either can’t afford the more expensive, higher quality products, or they are sacrificing durability for some other feature.

People buy German or American cars when surely everyone by now knows Toyota and Honda are bulletproof and easy to repair. And that’s a bigger purchase than any household appliance.
I'm surprised by this, as I had expected the opposite. Couples are spending a lot of time together being confined to their home without much entertainment, so I'd expected that to result in more baby making

> (most mining occurs on the grid)

The post you were replying to is disagreeing with this. Power made available for extremely low cost next door to a hydroelectric dam etc. might be technically "on the grid" in that there is some connection between that town and the rest of the grid, but if the long-distance transmission lines are already at maximum capacity (which is usually the case, otherwise power wouldn't be any cheaper in those towns than anywhere else) then that surplus power is de facto not available to the rest of the grid.
> The attention to details and overall quality make their gear literally “buy it for life” category products.

I've heard this was once true of Sears.
They're probably alluding to the stereotype that boys are more adventurous and girls more risk-averse, which informs why motorcycles are marketed mostly to boys/men.
A future where the environmental impact of PoW is minimized sounds like a great future. That future does nothing to slow the ongoing climate crisis today and it does nothing for the vulnerable people in coastal areas, hot climates, etc tomorrow. If we were talking about 'NFTs once PoW is not environmentally hazardous' that would be great, but we're talking about NFTs today.
Most people never learned computer science. Few programmers I've met have.
There is a lot of financial information (which is private by default) which is irrelevant to a person’s current tax obligation.

Interestingly, the amount of real resources (as percentage of GDP) spent mining gold have increased since most of the world went off the gold standards.
The "problem" is with the people who missed out on Bitcoin and can't compete with Chinese miners.

I started out mining BTC on a Core2Duo laptop from 2006, in 2010. I upgraded to a Butterfly Labs Jalapeno miner. Then I started to realize Chinese miners were soaking up the mining equipment and many of them were getting industrial power rates.

Then people who couldn't afford / acquire BTC ASIC miners made more ridiculous alt-coins that they could mine with GPUs. Cryptocurrency isn't the problem, people butthurt about missing out and wanting to make their own coin are the problem.
> The post addresses this question in detail. In brief summary, extracting "green" energy from the grid (most mining occurs on the grid) means that the energy available on the grid is more likely to be from CO2-generating sources.

This is a hypothesis, but where is the evidence, i.e. actually increased CO2 emissions? My argument is that most of this mining is using electricity that would otherwise not be used or produced. That is why it is so cheap in the first place.

One major scam that's lower effort here is that you can simply sell someone else's digital art. Selling physical art forgeries has always been a thing but the risks involved in doing it (i.e. what if you get caught) and the costs (faking a detailed painting isn't EASY) mean it's not as attractive as just grabbing some Japanese or Chinese artist's stuff off Pixiv and selling it as an NFT to english speakers, where the original artist may never find out about it.
Both sides of this have pretty good counterexamples. There's an experimental way to encode data on crystals (using lasers, I recall?) that last a very very long time. The more feasible example though would be archival tapes used in long term cold storage, that also do quite well.

For physical medium, given the right storage conditions, you can store film for quite a while, and that technically has infinite resolution in comparison to a digital copy.
