Some Mining Pool Operators (MPO -- or simply miner) offer transaction acceleration services in Bitcoin where transaction issuers can pay miners off-chain (privately) to get their transactions included ASAP, frontrunning other transactions in the queue. Examples of such services include [3; 4; 5]

Then, after publishing the paper "Selfish & opaque transaction ordering in the Bitcoin blockchain: the case for chain neutrality,"[1 and 6], which shows that MPOs deviate from some common assumptions in Bitcoin, I decided to investigate further some of the transactions accelerated by MPOs. So I did a bunch of empirical experiments and noticed that these services work pretty well.*

I also noticed that some Bitcoin transactions include arbitrary data through the OP_Return opcode, which enables applications to be built on top of the Bitcoin blockchain. For example, the Omni Layer (https://omniexplorer.info) allows users to issue transactions that send USDT to other Omni addresses. However, on the Bitcoin blockchain, the transaction input/output is worth only a few dollars, making it hard for transaction monitoring systems to track the actual value of transactions.

For example, the following txid "ba05a61af97424b340358c2d97080236767ee5b9811d90773f86c35b1ce7f022" sends 13 million USDT through Omni but in the Bitcoin it shows an output of 27,072.48 USD where 27,058.87 USD is a change and a fee of 1 USD. We can retrieve the Omni value by parsing the OP_Return tx output from Bitcoin tx data.

The PDF file (see [2]) shows a draft of a preliminary analysis where for all 313,575,387 transactions issued and mined in Bitcoin from Jan 2018 to Dec 2020, 42,832,713 (13.66%) contain OP_Return opcode, where:

- 17,993,300 txs belong to Omni Layer Protocol (an average of ~111 txs per block), representing 5.74% of all issued txs and 42% of all OP_Return opcode transactions. Of all Omni txs, 97.27% belong to the Tether USDT token.

- From our set of inferred to be accelerated transactions (following methodology in [1]), we have that 1805 OP_RETURN txs were accelerated. From this set, 1740 accelerated txs belong to Omni Layer Protocol. 1739 txs belong to Tether token (USDT) and 1 to Omni token.

Question: I understand users would want to accelerate the inclusion of transactions in DeFi (e.g., in Ethereum), but why would someone want to accelerate Bitcoin transactions?
I'm still struggling to find reasons why someone would want to pay for the acceleration of Bitcoin transactions.

Thank you in advance for your time and any insights you have!

There's no one approach which works for all locations and scenarios. There is a relatively fixed set of requirements for survival: air, shelter, water, food. Tools, equipment, and infrastructure.

The scenario initially proposed was a supply-chain disruption long enough to plan for at least one, and perhaps a substantial number of planting / cultivation / harvesting scenarios. In any significantly urbanised location (and Singapore is very highly urbansied), there's simply not enough arable land to provide food for the local population.

As a rough estimate, one person requires about 0.5 hectare of land to support them. Singapore has a population of 5.4 million on an area of 733 km^2 (73,000 ha). Given the per-capita requirement, the area could support a population of about 146,000, or the population of 5.4 million would require an agricultural area of 27,000 km^2 (2.7 million ha).

Considering other possible scenarios (hurricane / typhoon, major flooding event, tsunami, earthquake, wildfire, etc.) it's quite possible that structures or containers for large-volume storage would be destroyed, damaged, and/or contaminated. Again my point with water being that large quantities are required even in reduced-usage emergency scenarios and that quality and not merely quantity matters.

In most of these scenarios, your energy budget to a substantial extent is your body's own muscle power. That might be supplemented by fire (do you have fuel), animal power, or (do you have fuel) engines or generators.

Many regions have official or unofficial groups which provide training and coordination for disaster planning and contingencies. Participating in one locally might help in moving understanding from a theoretical to practical basis.

Across all markets, the primary markets are doing okay. (just okay though, in the sense that new ventures are getting funded, new bond issuances are getting subscribed, new NFT series are getting launched just fine, new cryptos are bought up, venture and hedge funds getting large amounts from limited partners). The secondary markets are puking everywhere, and thats what people see with the charts and headlines. But that doesn't matter for the entrepreneur, they already got people's money, in the web3/crypto-space some of the builders actually use that money to develop something and subsidize their time to push for protocol improvements that do make crypto-everything incrementally more usuable, just in time for the next bubble with a larger population.

The answer is that you should not believe that. Herodotus was unable to accurately report on what happened 100 years before he was born. But also, the (popular) books on antiquity I seen made no secret of that. Also, blog articles by historians I have seen were careful to point the same out.

What I don't see mentioned here is the issue to redirect the user from the captive portal browser back to its own (preferred) browser to display a landing page after acknowledging the TOS. On Android this seemed completely impossible and I noticed several implementations where there was simply requested to copy a link. On Apple any link with target blank would open a new Safari window. I'am wondering if this changed with later Android releases
The point was the resource is available and cheaper than any alternative, not that they are actually going to say replace everything else.

Wind really scales best with hydro as you only get so much rain per year, but you have a great deal of flexibility when you release it. As Finland has a great deal of hydro they can make use of plenty of wind.

Until any FSD solution delivers, it's far too early to vindicate the mobileye CEO. As it stands, even with additional (expensive) sensors, it seems very likely that ML will be required regardless.

> This is the sort of thing I learned in history class as a teenager

My observation from discussion about history (including on HN) is that most people
did not learned the same thing. My own history lessons in high school definitely did not taught that. Instead, many people assume whatever they learned is definite and any new addition or emphasis on something else is bad.

> Primary sources are valuable but should be put through the filter of partial knowledge of a situation and personal bias.

Yes, but also to interpret primary sources, you need to understand quite a lot about that period. What they mean when they say certain words. What knowledge is assumed, what values are assumed by the orignal writer. History is foreign country, it is very easy to misunderstand their priorities or what they write about.
Is that 12 miles a day a single commute? i.e. 6 miles each way?

Personally I'd just ride my bike for that and if I was unwilling or unfit to cycle 12 miles a day[1] I'd go with an electric bike.

No they're not, as already pointed out in response to your other comments (e.g. https://news.ycombinator.com/item?id=32092280), yet you continue to cite them as an authority.

Not to mention the other comments that refute those numbers using the same paper - projects would be closer to ~$100/KWh when storage is taken into account, as shown graphed in the paper itself.
Most content isn’t funded through a VC model though but a more traditional publishing one where you get advanced the money to make the content with a contract that lets the publisher recoup first and then take a percentage of revenue.

Netflix is a publisher in this context but only sells through its own channels so is more analogous to console manufacturers in games. Their problem is basically having a low barrier for competitors to enter and they all own more compelling first-party content.

Most VC funded companies are doing more than producing content or are opening markets. Which isn’t to say the games investment hype cycle hasn’t been very silly lately but it’s more often a bet on technology and/or a potentially emerging market.

I think that's a way too positive/naïve viewpoint. For the transportation model to change, infrastructure and services are needed (trains, subways, trams, buses, everything around them like stations, signaling, staffing, ticketing system), as well as appropriate density and city layouts ("transit oriented design" in the US, "common fucking sense" everywhere else). Those won't just happen overnight because car ownership is more expensive. There needs to be significant buy-in from the population, politicians, and money. Those are present, to different extents, in most big cities in some places (e.g. Europe(including Russia), China, Singapore) but really aren't in some other like US and Canada. Car ownership would have to get a whole lot more expensive and impractical before Americans who think buses are for the poor and homeless realise the inefficiency of "a vehicle per person" and accept the investment and lifestyle changes needed to switch to a more efficient model.
You act like there aren't people who do things called "lifecycle analysis" professionally.

This is not new for BMW. I have a 2016 and if I want my phone app to work, like location or open/close the doors it's a subscription. And Apple carplay was also a subscription. I tested the app the first year and was so bad... and try to enter am email and app with a wheel to scroll all alphabet just to login in the car. Horrible interface. Once I closed the doors in the app and they never closed. They are not getting new costumers. So they need to find a way to get money from the current owners.
Keep in mind that wind and solar power figures typically quoted are for max effect. For solar that means noon on a cloud-free day. Most hours of most days, and all the nights, are not like that. So if you want a realistic comparison with something like a nuclear reactor, which can run steadily for months on end, you need to apply a significant multiplier for additional area and batteries.

I feel the same towards the article, I think that the moment you need to resort to "think of it as..." it's the moment you lose me.

I also don't think he does a good job at explaining the biggest source of misunderstanding. Quoting the article:

`Expressions and statements are distinct things.`

That is not really correct.

A function call, e.g. is both an expression and a statement:

`foo(bar)` on it's own is both an expression (it returns a value, even if the value returned is undefined) and a statement.

In fact, determining if a piece of code is an expression or a statement in all borderline cases depends on the context.

```

const foo = function bar(){};

function bar(){}

```

On line 1 the bar function is an expression, on bar 3, is a statement.

There's nothing really about the function on it's own that can tell you whether it is an expression or a statement.

On the other hand, a nice way to differentiate statements from expressions is that you cannot use statements where you need expressions.

```

console.log(if (3 > 2) {})

const foo = while (i < 3) {}
```

both lines are syntax errors.

Ya, and paying your taxes can be a long and arduous process too. That doesn't mean it's ok to just skip all the hard work.

Going public is not difficult "just because". It's difficult because there are a lot of reporting and due diligence and research and compliance required before your company is opened up to the public market for investment. It's there to keep garbage companies like Truth Social from going public and bilking unsophisticated investors of their money.

It seems to me that a spac is just a technically legal way to get around the spirit of the law.
so we didn't learn anything. Sad to know.
That idea crossed my mind as well. The issue with that is the fact that the heater is already installed. So either:

* BMW charges everyone for the heater, but don't enable it.

* BMW lose money on the installation of the heaters, and overcharge subscribers. The subscribers need to cover the cost of the heaters in the remaining cars.

* A combination of the two, where everyone pay part of the heater, but the subscribers still have to pay some part the cost for non-subscribers.

There is no way around it though. Either BMW is scamming everyone or the subset of customers who are paying them the most.

If I opt for paying for the winter months only, the product is still overpriced. It has to be.

It's indefensible. You cannot launch this type of "service" and be the good guy.
Let's say you are bored out of your mind at a party or while waiting in line for at the bank and tell your friend "LETS FUCKING GOOOOO". It might not be anger but definitely not enthusiasm either.
That makes more sense - it's like networking vendors who sell switches that physically have 48 ports, but you've only paid for 24 and for an extra license you can activate the remainder. It's easier for the vendor to manufacture and supply one single type of hardware, and it's more flexible for the consumer because if your needs evolve (you want to drive faster or have more ports) you can pay just for the upgrade and start using immediately, not a whole replacement.

Paying a subscription for a feature that doesn't require any effort om the BMW side (e.g. not the continuously updated infotainment system) is what makes this different.
Person in the middle. If you want to replace man with a generic form, use person. Monster is childish, and lazy.

> I’d love to hear how you ... enjoy this music ...

I can’t say I do enjoy that music, to be honest. When I was in my late teens and early twenties—as I said, around forty-five years ago—I was attracted by the notion that some 20th century classical composers were breaking new ground, throwing off old-fashioned constraints, being revolutionary, etc. I had studied traditional music theory and learned to play Mozart, Haydn, Beethoven, etc. on the piano, and those more recent composers’ formal experimentations seemed exciting. My youthful rebellious infatuation with their music didn’t last long, and ever since I have listened to more conventional tonal music—not only Western classical but also rock, folk, jazz, reggae, etc.

I did get a bit more out of Elliott Carter when I was young, though, than I did out of other avant garde composers. Amid all the disorder there was something trippy and emotive about his music. These days, for a similar effect, I listen to Bach fugues, which have been mentioned by other commenters here. If anyone is interested, here’s an arrangement of the Art of Fugue that I listened to for the first time the other day and really liked:

This is adjacent to one of my main complaints with Racket's contracts. If I want to use Typed Racket (which I almost always do) then it becomes significantly more difficult to attach non-type contracts to code. I find I often run into cases where I want to encode something as a contract that is impossible to describe with refinement types. Especially when gradually typing an old untyped codebase.
