I learned this the hard way as a 16 year old, I was absolutely infuriated they could fine me 1000s as a kid when government schools taught me "taxes are due April 14, end."

(Yeah I never fell for the government's trick to always evade responsibility for everything by claiming they're multiple distinct unrelated entites "oh we are XYZ, so ya know we pretend we have no responsibility for the actions of PQR when in fact both are The Government, one coherent whole")

Yes, I'm saying there are no trade-offs between PoS and PoW. If there's one I'd like to know what it is.
Thank you! I've been meaning to ask Oban people about this. Sadly, while Exq has been rock solid for us the last few years, Oban seems to have a ton of active development and features we wholeheartedly want to adopt. Just haven't had the time to run tests :)

Our workload is highly bursty. We queue about 20k jobs in the morning, which themselves queue another 100k-150k jobs. Then hourly we queue additional ones. I'm concerned about the Postgres overhead of inserting thousands of rows for jobs, each with potentially their own transaction.

With Oban, we can actually get rid of Redis in our stack (currently using it for Exq)
lmao, sand is being pounded

for anyone passing by: it is impossible to tell from blockchain analysis if anybody sent a payment to a particular Monero address, as neither sender, recipient or amount is stored in transaction data or onchain anywhere. Even client side, the data is limited.

Even if the US Treasury seized the recipient's wallet and had it open to look at all transaction history, Monero protocol doesn't tell you what address payments were received from, so the US Treasury would not be able to use their wallet and then compare it to US exchanges or other covered persons to say those people violated sanctions.

On the contrary, I do think Monero wallets show what address you sent to, so if they seized an exchange or a covered person's wallet they could see if they sent to that sanctioned address. But of course, the person on the OFAC list has infinite subaddresses to rotate to.
The key difference is that I'm certain that Facebook makes continuous efforts to use less energy. Maybe not for environmental reasons, but they have an economic incentive to increase efficiency.

Regulating the energy consumption/efficiency is more akin to fuel efficiency standards for cars.

>but comes at the great cost that people who aren't already in the game won't be able to acquire Ether without basically paying cash for it. That's a weird dependence on fiat currencies for a 'decentralized ledger'. (And yeah, there might be other means, but none of them are really practical for the average person.)

There's no inherent weird dependency on cash, there's only a dependency on whatever currency people choose to pay each other for work, which currently happens to be cash.

If people started paying each other in Ethereum-based tokens, you could close the loop and cash would not be a dependency.

Sure, and I broadly agree that there's a collective action problem here; it's just that accurately understanding and addressing that problem requires a different level of analysis that's removed from raw anger about "handouts."
Good question. I think my perception is that finding and using them is a high bar of entry.

And the suspicion that Google doesn't do even a cursory examination would put me off of using anything that isn't independently vetted.
Software is hard. Chrome had this in 2008. Firefox had to be rearchitected 14 years for this.
How is the communication between workers handled? Their blog post about websocket support only advertised the possibility persist state via their key/value store, but here the workers handling different clients need to communicate with each other in real time. How is this done?

edit: Their "Router" class is a "Durable Object". There is no trace of this in their code, this is configured separately when creating the worker. A durable object is a durable JavaScript object, unrelated to K/V storage; it seems to essentially be a class whose instances act like service workers and can respond to requests using their persistent state. I guess there is special support for WebSocket endpoints in their Durable Object system so that a WebSocket endpoint can be sent to/from the Durable Object.

Their docs are really not optimal, with many different iterations of the syntax mixed together (e.g. some thing only work with the "Module syntax" but every single example is written with the "addEventListener syntax").
I understand what they wanted to achieve, and I understand that they cannot achieve this. Seems that burning absolutely enormous amounts of energy is the only secure way of doing it. I guess rather than fight the universe, we better find a way to do it cleanly!

Wow this is insanely inaccurate and downright dangerous advice. If you listen to this comment and things go sideways you can literally lose major assets or even be imprisoned.

1. You must pay estimated taxes if you earn more than a certain percentage of last year's income without taxes withheld. You emphatically do not have until the next year's tax filing deadline to pay your taxes. Estimated taxes are due quarterly.

2. If you invest the tax portion of your income and it loses value, you still owe the original amount. So now not only do you need to liquidate that investment but you also need to pull money out of other areas to cover the loss.

3. Despite pseudo-libertarian propaganda to the contrary, money you owe in taxes does not magically become "your money" just because you haven't written the check yet. You shouldn't invest money you can't afford to lose (especially in crypto of all things) and you can't afford to lose Uncle Sam's money.

4. One of the only things the IRS won't take from you is your primary residence (but they will put a levy on it, making it impossible to sell or refinance until the debt is paid in full), so using tax money to buy down home equity is one the stupidest things you can do.

Talk to a CPA before making huge financial changes, especially if the entire reason for the changes is trying to make money by arbitraging tax funds.

YouTube also promotes conspiracy theories, racism, anti-intellectualism, authoritarianism, anti-vaxxing, and so on. These things pretty severe negative externalities, to put it mildly. So let's not pretend that YouTube's existence is a net-positive for humanity; that remains to be seen.

> people are saying it will take 10+ years

Who is saying that? Genuinely curious. It has strong buy-in from Apple, Google and Mozilla, and all 3 are implementing the spec right now (and updating implementations as the spec changes). Seems very doubtful that it'd take anywhere near 10 years to be supported by major browsers. I guess it depends on what subset of graphics/compute features you need for it to be viable for your specific use case.
This website seems pretty biased to show national currencies in a bad light and bitcoin in a good one.

I do think there will be some centralization at the exchange level. As of April 2021, Kraken had 600,000 ETH staked for ETH2 [1].

It's not in the interest of Kraken or Coinbase to disrupt one of these PoS networks, but there is some barrier to entry for staking ETH2 or other PoS coins on your own, vs staking them on an exchange. In the case of ETH2, if your staking node goes down, you get slashed and lose some ETH. If there isn't slashing (not all PoS coins have that), I don't see what guarantee of network security or uptime there is.

I'd be curious what PoS coin experts think about this part. It seems like PoS / staking can lead to centralization. PoW has energy concerns for sure, but it has so far demonstrated decentralization pretty well.

I'm legitimately curious about this. I'd love for PoS to be feasible and am trying to understand it more.

In my view (of his view) - that in many cultures we see today, we've come to vastly underestimate the importance of sleep. For example, we've removed afternoon naps from workday routine (with field evidence showing effects on health such as heart disease (against comparative groups who haven't stopped taking naps - but not lab-controlled I think) etc.) We sleep less.[2]

We shouldn't be asking what's the purpose of this pesky thing called sleep (which evolution turns to always incorporate into animal life, however inconvenient it is[1]; to route around the inconveniences as it were, rather than the other way around). We should rather be asking, is there a single function which isn't improved by sleep (Walker thinks no). End of preach rant :)

[1]: e.g.: some birds appear to sleep in patterns such as when there's a row of birds sleeping, the two birds at each end sleep with one hemisphere each - but opposite ones - so that the field of vision is maximised. At midpoint in time however they swap places. The rest of the birds sleep with both hemispheres. That sounds pretty cool.

[2]: though apparently there's criticism directed at Walker re: this, and re: him not mentioning that mortality appears to increase beyond the 7 hour mark (but I'm just learning this, so basically, just a fair warning not to take all of this at face value, there's nuance).
> smaller operations and hobbyists will rush in to fill it. Hash rate gradually climbs back up and instead you have 10x the energy usage because you can no longer run the PoW in a scalable way.

This is false. Miners will spend about the same amount of money they get from block reward to run their operation. Asymptotically, this money is spent to buy electricity. This is the result of competitive pressure from other miners. What you will observe instead is the same amount of electricity burned but with 10x less hash rate.
Of course. Look at the 2012 London olympics. This is a use case that surprised Apple designers too.

> Sleep is a whole-body process of repair and optimization.

This is what I felt when I watched the Netflix documentary "My Octopus Teacher".

At some point, the octopus was vigorously attacked by a shark, which cost her a tentacle. She was bleeding and retreated to her den.

The attack made her very weak. She could no more change colors, nor get out of the den, even to get food.

After a week or so in the den, presumably sleeping, she started recovering and her arm started to regenerate.
The sales people are always on about how easily people "abandon carts" due to small friction. Lots of things people buy they a) don't need that urgently or b) can buy somewhere else. Some fan shirt off TeeSpring is very strongly in the "not urgently needed" category, your powerwasher example might very well be too and can be bought from tons of places.
The elephant in the room is bitcoin literally requires the mass consumption of computation to work - the more the better. And it was designed this way. In comparison, Facebook and industrial processes work to make their processes more efficient and use less resources for their workload. Bitcoin will just gobble up any efficiency to do more mining and end up consuming the same amount of resources.

Bitcoin is an endless energy pit. The same isn't true of things like Facebook.
Saved in my note, much appreciated.

Yes, I agree building a UI library from scratch is hard and probably not worthy doing (too many people tried and gave up in the middle; probably better to channel that enthusiasm on improving existing ones). I should state that more clearly. I was looking at something more modest, like a canvas implementation based on wgpu that enables others to build their UI libraries on top.

I guess it would be something like Skia, but it also sounds like a tremendous effort, and I could probably just use Skia instead. However, I guess I am not going to match what Skia has (maybe what HTML canvas has is enough?). Also, I have played with skia-safe crate but I personally feel the dev experience could be better (not to blame skia-safe, it's wonderful and even provides a build process that automatically downloads a precompiled skia library).

Thanks for pointing out Iced. I didn't know they are using wgpu under the hood. I will take a good look at their code. I have been reading nannou's code to learn how to work with wgpu. If we skip my last paragraph, I think building a UI library on top of nannou is pretty doable.

It still frustrates me that legitimate Paypal e-mails include really big "click here to login" buttons that link you to their website.
Such links are considered a hallmark of phishing, and there are many attempts to prevent people from clicking on such links. Many services I use include text like 'we will never send you such a link you know how to get to our website'.

The fact that paypal does not do this normalizes clicking on links in e-mails.
It works when 1..n of your tabs are frozen, but the UI is still responsive e.g. you are still able to switch to other tabs. If your chrome is completely frozen i.e. you can't even open the chrome task manager, then you usually have to restart the browser.
The last sentence comes off as a rhetorical sleight of hand. You can be against censorship of books and music and still believe that the government has a role to play in regulating dangerous goods like plutonium. The trade of goods with an outsized environmental impact is regulated today, though this mostly shows up as restrictions on chemicals that are themselves direct pollutants.
> edge cases

That’s the first time I’ve ever seen someone describe Facebook as an “edge case”.

If $900,000,000,000 of market capitalization counts as an edge case, I’d think you must be hard to please at Christmas - those are some really high standards!
Bitcoin isn't the only option. We've already seen that when the price of Bitcoin dips miners flip over to whatever cryptocoin seems next to bubble, seems next most interesting. Certainly what is called Bitcoin itself (today) has "hard" "deflationary" "caps", but as soon as miners get bored with that, there's always more room for more forks and other coins.

Even if Bitcoin isn't intended to be "growing forever", the ecosystem can and will.

> M1 mac pros were always going to come.

When the "new" Mac Pro was announced, the shift to ARM processors for MacOS was at most rumored and it also wasn't obvious that such a CPU would perform well.

If people knew this was "going to come", they would likely not have invested a significant amount of cash into a platform that was already on its way out.

> One constant of computer industry, there will always be the next chip, the next computer, and by then, the fancy M1 Mac Pro will become obsolete.

Unlike the incremental improvements you get with each new Intel CPU generation, this is quite a disruption. The PPC Macs soon were obsolete after the Intel Macs came about. All the efforts went into the new platform.

> Its day will come when everyone says "oh that M1? that was a slow POS that is now ewaste"

Things don't move that fast anymore. Take a 10-year-old Intel CPU, it's still quite capable. That certainly wasn't the case 10 years ago, or 20 years ago.
That's a strange definition of "sophisticated" you got there.

Modern Warfare 2019 Account “Permanently Banned” for Launching Game on Linux
There's a hidden subjective value judgment built into the word "excessive" that's doing a lot of the heavy lifting here. These "regulation" comments tend to have a high likelihood of boiling down "I want the government to stop things I don't like", where environmental concerns (crypto) or data collection (adtech) is a mere pretense grounded in incomplete information at best, emotion at worst.

Personally speaking I find it just as irritating of a pattern here that knee-jerk calls for "regulation" (i.e. bring in the coercive power of the state) or outright banning are so often floated as a/the solution to every problem. When legal coercion is suggested, it is entirely proper to bring up the existence of the dragons that lay down that road.
Can't agree more with this. I've used both, Rails since a few years ago and Django for about 8 years or so, and while I still like Django I think rails is far, far superior in every aspect. The only thing I like more from django is the migrations system (not even the ORM, just the migrations) and maybe the admin as a tool to browse the database. Other than that, Rails all day.
Maybe a 256-bit bus with four stacks of 16Gb dies. Apple could easily be the first customer for a new DRAM chip because they're willing to pay a premium to have the newest and best components and they are willing to guarantee large quantity orders.
I don't understand. We clearly have general laws like "don't shoot people," rather than 320 million individual laws like "John Edmund Smith IV of Springfield, Ohio cannot shoot people." And we didn't start with laws targeting individuals and then broaden it later. "Don't shoot people" was the proper, general rule that addresses the problem of shootings. Laws like this seem to be pretty effective and desirable. I don't know why we wouldn't take the same approach with something like carbon emissions.
The question is not whether you pay a massive efficiency penalty for storing electricity as hydrogen (obviously, yes) but whether there are applications where you are effectively buying a set of useful properties for the losses you are "spending".

For displacing existing grey hydrogen from the chemical industry, a possible reducing agent in steel making, and other high temperature industrial processes it's pretty clear that the answer will be yes.

I happen to think that it is really unlikely that the answer for cars and vans will ever be yes, even if hydrogen could be made cheaply.

Whether it will have a role in other applications depends on a few things:

First, the structure of the future electricity mix. In order to ensure that there is enough electricity at every moment, we have to do a mix of things:
-"over" build variable output renewables so that the troughs in production are higher
-Intra-day demand side response
-Intra-day storage (almost certainly batteries)
-Dispatchable renewables like hydro
-Dispatchable sort-of renewables based on biomass
-Dispatchable fossil fuels (with CCS)
-Load-following nuclear

The reason why people think about hydrogen and other exotic technologies is that many of the technologies on that list either have limited available scope (hydro, biomass), are probably not really carbon-neutral (biomass, CCS), rely on unproven tech at scale (CCS, new nuclear designs), or have exceptionally high capital costs (any new nuclear but especially when at low load factors, CCS especially at low load factors).

So what most simulations show you're left with as a low-cost mix for most days is a combination of the first five. That still leaves you with two problems:
-What do you do if the average output net of load is very different between seasons?
-How do you provision for a 1:20 yr weather system without making your system vastly more expensive?

and one opportunity (which is also a challenge):
-variable renewables are cheap and getting cheaper so cost-optimal generation mixes build a lot more than needed for the average day in order to keep use of expensive biomass and limited hydro capacity to a minimum. As a result, electricity has low/no marginal value a lot of the time.

Second, the future cost of electrolysers. At current capex levels, they need to be run at max load all the time and still produce expensive hydrogen. Genuinely low costs like what BNEF thinks might be possible ($100/kW) allow you to run for only 20% or less of the hours in the year and scoop all the excess electricity up.

Third, the cost of alternative solutions in the areas where hydrogen is currently being considered as this reduces the value of any hydrogen produced.

I do agree that for passenger cars it's just not going to happen.
