This has been my experience as well. My intuition is that complex models have several pitfalls that undermine their practical value:

1) complex models make more assumptions and may be less robust to the world behaving in unexpected ways. It takes more effort for practitioners to thoroughly review all these assumptions.

2) complex models have more parameters, and thus require more data to train. This limits the scenarios where they can be deployed

3) complex models are harder to interpret, which makes them less useful for convincing people to take action AND increase the likelihood that a practitioner will make an interpretation error

Of course, complex models have plenty of advantages too. Under-specified models can be wrong just by failing to account for obvious, well-documented variations. Human judgement is required to select the appropriate model for a given situation.
Nothing else to talk about I guess. Coming on a year for pandemic restrictions in US/much of the west.

That's... called printing money. Inflation is a necessary evil and infinitely more preferable to the alternative that is bitcoin, which gives you no reason to ever use it. Why would you use it at 10k when it's going to be a 20k next month ?

Inflation encourages money changing hands. The market has absolutely fuck all to do with it.
This sounds like you just want to buy a video card for less money.
I don't understand where all these "cryptocurrency vs the environment" posts are coming from recently. The core problem is energy use, no? Things using electricity - of which bitcoin is a huge one - are powered by environmentally damaging supplies.

I don't care about BTC at all, but if it were to be wiped out of existence tomorrow it would prevent further damage to the environment in exactly the same way that getting rid of plastic straws stopped plastic polluting the ocean.
Maybe in the beginning but today miners make lots of choices about where to build/expand their operations based on energy costs, government policies, energy source and more.

It’s hilarious to see the coin bros attack this article. The point here isn’t the number, it’s the scale of waste, which is astronomical.

I would rather protect the environment than someone’s ability to buy drugs online. What other legitimate purpose does btc serve right now other than illegal activities?

Do you think, just because you do software, you understand agricultural sciences ?

All the warming is actually going to make it harder to farm in already existing areas.Frozen land that has thawed, would lack the soil type to grow anything of value.

It's a cash-grab with social justice written all over it and pseudo-science justification sprinkled on top, of course it will shoot to the top of HN.

They are distrustful of decentralized bottom-up economics and they see a flood of interest in BTC, and, in this case, the gravest of sins has been committed -- there is economic activity that cannot be interdicted for extraction of payment or imposition of equity. Of course it must be outlawed.

That's a weird re-phrasing of "they caused the stock to drop by manipulating the market through blocking buys".

Bitcoiners use the cheapest energy they can find in place where they can cheaply install hash power.

Some of that may be hydro. A lot is coal.

Even when they do use green energy, the effect of doing that is to displace other users onto dirtier forms of energy, thus creating just as much pollution anyway.

Bitcoin is not green in any way whatsoever. Bitcoin specifically wastes energy, by design. This is never green. The first principle of green energy is to use less energy, as no energy is clean.

It's a small red cocktail flag to me, something that needs verification and but not bad enough by itself.

As usual read the rest of the ad, talk to the recruiter, read reviews and see if your worries are actually real.

Job ads are placed by HR people that are not always aware of how sensitive we are, they should be and ads should be reviewed by the actual hiring manager but that doesn't always happen.
You could make up some fear mongering "study" about almost every energy using topic. AI and video rendering for instance which is often for some marginal purpose. Or heating pools, idle electronics, big homes with AC, leisure travel, all the useless crap bought and manufactured in China with dirty coal, etc.
Hence it is and should be named DLT. The "Distributed" separates it from merkle tree systems.

There are lots of popular tropes of how our brain works and I'd agree with this author that they are oversimplified and generally incorrect - I'd add the left brain right brain divide to the list. However the author appears to be arguing from a position that they (or someone) actually know how the brain works - having done a neuroscience degree, my one take home was that when it comes to modelling the brain against our conscious experience - we really don't know anything.

I just don't see how this thing will ever carry humans. They can get to the point where it is perfectly nailing 100/100 landings every time without fail and it still wont be safe. One single gust of wind at the wrong time, and everyone is dead. No go-arounds, no ejection system, no aerodynamic ability to correct. Starship can potentially revolutionize cargo access to space, but there's nothing in the history of aerospace travel even remotely comparable to the level of risk this would be taking on.
This uses riscv-formal. The default way to use riscv-formal is bounded model checking. It verifies all single instructions and some consistency checks, e.g. register read matches last logical register write in presence of reordering.
The whole point of inflation is that your money is actually used to do things. Were those currencies to deflate, it would literally be more beneficial to not touch them. Ever. Investments would grind down to a halt, and why would you do groceries now when you could get more if you waited for next week ?

Even as a hardcore socialist, it's worrying that cryptobots have failed econ 101.

Maybe rather than expanding your assumptions one checked privilege at a time, just drop your assumptions altogether? You simply can't know the experiences of others; even direct communication only transfers a very loose approximation of experience, and that's if both sides are both communicating earnestly and are skilled communicators. So if you can't know the experience of just one person then you certainly can't group people by their experience.

Generalisations are a poor substitute for empathy and curiosity.

But that's all very abstract so to concretise my point:

> Those assumptions will however impact my decisions - who I vote for, what charity I donate to, how I approach other people in life, etc

I try to support people who don't play zero sum games, who create lasting systemic changes. Some fraction of most political movements are based on this, while other parts are about tribalism - so try to back leaders who want what's best for all.

To cast people in terms of privilege is to make moral judgements on people based on pure circumstance.

And approach people as if you know nothing about them - because you don't. To think you know something about someone you don't know is literally the textbook definition of prejudice.
Why bother explaining it to you? I recommend you try to work in other areas.
Third generation cryptos like Cardano/Ada, Polkadot and others using proof-of-stake instead of proof-of-work to generate new blocks are orders of magnitude less energy demanding and more efficient in terms of transaction speed and costs than bitcoin and ethereum. Bitcoin has, unfortunately, become synonymous with cryptocurrency in many people's minds. It will be interesting to see what happens with the value of bitcoin as these limitations relative to the new kids on the block (sorry, pun intended, showing myself out the door etc.) become more obvious.

I am thinking of moving to Tidal. The Spotify sound quality is awful for Classical music with their compression/processing unable to deal with complex passages. The Android app also upsamples everything to 48KHz and has occasional random audio glitches. Hopefully Tidal is better.

This is a bizarre, seems like there is a personal issue here and perhaps the board should have a look at this? This is one of the areas that CEOs seem to have a lot of opportunity for odd behaviour, what with Benioff spending billions of his companies money on companies that he has invested in etc..
Patently false. I do a lot of contracting work for miners, they specifically tune their operations to the power cost of an area and in variable rate loads will switch off miners during peak costs. $/kWh is a big concern for actual mining operations, maybe not for people with one or two rigs in their basement.
Have you looked into the energy consumption of a 50 year old refrigerator vs a modern one to determine that the modern one is an environmental harm?
Right, and all those things are harmful to the planet.
These are just filler articles, guys. I used to write nonsense like this as a teenager for a living. You kind of want just some base load of published content on your website so you hire some cheap labour to do it.

Occasionally someone gets upset about it and shares it. Didn't happen that much in the past but happens more commonly now.

It has all the signs:

* No meaningful information

* Filler phrases to pad content

* Some amusement for the writer with some phrasing

Anyone reading anything into this is kind of wasting their time but it's okay, it's kinda designed for that.

Cheap is not necessarily renewable, but is often just a cheaper country which in turn tend to be more lenient.

Also, it is wrong to assume that consuming 1GW near a hydroplant is fine. That 1GW would have been sold to someone else, and unless the net has an abundance of renewable energy, a non-renewable plant is going to have to cover for that.
But then none of his enterprises have been explicitly exploitative, unlike many billionaires, and he’s pushed the car industry into moving away from combustion engines, so personally I give him a pass
Interesting. My native language, Afrikaans, has a lot of influence from both Dutch and German (as well as a bit from English and quite a bit from Bantu African languages). We say "eenvoudig" for "simple" and "maklik" for "easy". I recognize both the (different) Dutch words Google Translate provides me when I translate to Dutch as similar to the Afrikaans words, but Google Translate translates both to "einfach" when I translate to German. May be German for some reason conflates the meanings. That said, homonyms and homophones that conflate meanings are found in most human languages, and often for meanings that are far easier (or is that simpler ;-)) to distinguish than "simple" and "easy".
I'm kind of skeptical of formal verification. For instance, it wouldn't have prevented bugs like spectre or meltdown. It can only tell you that your implementation matches some spec, but your spec can still be incomplete or buggy. At the end of the day, there's no substitute for extensive real-world testing.
Yes, clearly the market will solve this problem for us.

Do you run Docker under QEMU or QEMU under Docker? How does that work exactly?

There are different articles which claim different things. I think the first article is the best.

> The CCAF’s research finds that 76% of ‘hashers’ use renewable energy to power their activities, with hydropower the number one source at 62%. Wind and solar energy meanwhile are used by 17% and 15% respectively. This would appear to be consistent with previous research which estimates that 74% of bitcoins are mined using renewable energy. However, the CCAF’s report specifies that the 76% refers to the share of hashers who use renewable energy at any point. It estimates that only 39% of hashing’s total energy consumption comes from renewables. [1]

> Bitcoin, which is mostly mined with electricity from coal.[2]

> But most bitcoin mining facilities are located in China, which is still heavily reliant on coal-based power. Though the Chinese province of Sichuan is known to attract miners due to its cheap electricity and rich hydropower resources, the level of power generation capacity fluctuates depending on the season.

Yep, which is what makes "creates a copy" in this warning seem like "copy and delete". Because just creating a copy and not deleting the original is nothing at all like editing storage class.
I strongly disagree with this.

The tax code is relatively straightforward for a programmer. It’s a bunch of conditional statements and simple math. Even the cases you mention are straightforward compared to the usual ambiguity that comes with engineering a product.

TurboTax is awful software. One question at a time, their user flow is AWFUL. Truly abysmal design for even the simplest of tax situations.

The IRS’s free file fillable form site is similarly awful; their asynchronous, background xml validation of forms after they’ve been submitted to notify you that their system let you input something invalid is a laughable system design.

This market is ripe for disruption. I do feel that should come from the government itself, but that seems unlikely for political reasons.

When junk science is peer-reviewed, it's even more of a problem.
"Exceptionalism" is pretty common among many cultures. The term "Chinese Exceptionalism" is used pretty widely these days.
Not true. We have actively sought the cheapest electricity sources for our rigs. I guess it depends on the scale you're operating at, but you're not going to be too profitable plugging into your apartment wall socket here in Central London @ 20p/kWh!
The biggest polluter in the world is the US military and crypto has the potential to defund them.
Hardware mixing was killed, because it turned out that it is more efficient to mix several streams with CPU and move just a single one via the bus. It was also more flexible and without weird limits - for example, GUS could mix 14 streams at 44,1 kHz, and if you went above (up to 32), the frequency of each stream went down.
My initial reaction was skepticism. So the numbers I found were 121 TWhs consumed by Bitcoin annually. Hydro power produces 4200 TWhs annually of a total electricity production of 25,000 TWhs. Assuming all Bitcoin mining is powered by hydro, a 97% untilization for hydro doesn't seem far-fetched.
STOP using whataboutism as an argument for crypto it's just pathetic at this moment.
I think it's more that they've tried and failed.
Your comment suggests the inverse of the linked document. You suggest scroll, where they suggest auto.
Wouldn't it be interesting if you had a free streaming service but you had to down a program that mined crypto on your machine?

It might also be a brave-like service where you can either buy Dorsey dollaroos (what I assume the logical name for a new crypto by square would be) or click on ads, then use the dollaroos to buy streams.
> it's not overpopulated.

I'm sorry, but this is just a ridiculous statement to make, except maybe if our opinions on what overpopulation means are vastly different.
> Because that would be absolutely pointless.

You are actually arguing that it's pointless to incentivise usage of clean over dirty energy. Do you own a coal mine?

> The value of crypto is proportional to the future cost of minting. No future cost == zero present value.

This argument requires some evidence. I was under the impression that scarcity of the asset underpinned the value.
This is not true. Miners are sophisticated business enterprises that select mining farm locations carefully based on access to cheap power and natural cooling. People signing their gaming rig into the network aren't a factor.

DLTs (blockchains) solve the double spending problem in a decentral (trustless) way. Thats "the definition" and what separates it from other similar tech like git, a synced databases or a write-only database.

Selection bias. I don't doubt that the miners who are investing god knows how much is necessary to _require a contractor_ will have scaled enough to need to concern themselves with cost of electricity, but the _majority_ of miners are not going to be those people, surely?
Tidal is an also ran. Jay-Z made the right call here. Jack Dorsey not so much.
