Bitcoin also spends about as much money as a fly landing on an aircraft carrier. Sorry Argentina, but you just don't use that much electricity in the context of the global economy.

Companies like Tesla are buying Bitcoin, not because they intend to transact with Bitcoin but because it gives them protection against inflation within the US economy, and it gives them a stash of money that cannot be forcibly shut down, allowing them to do business even in jurisdictions that don't want them there.

If you are looking at just the "products and services" you are missing the forest for the trees.
It isn't good for all regions. Just like swamp coolers aren't good for all regions. But the point is that "resistive heating is the best you can do if you want to heat your home" is just plain wrong.

In that context, it's absurd, to put it mildly, that she said this quote in her Jan 2020 layoffs letter:

> You may recall that we expected to be earning revenue in 2019 and 2020 from new subscription products as well as higher revenue from sources outside of search. This did not happen. Our 2019 plan underestimated how long it would take to build and ship new, revenue-generating products. Given that, and all we learned in 2019 about the pace of innovation, we decided to take a more conservative approach to projecting our revenue for 2020. We also agreed to a principle of living within our means, of not spending more than we earn for the foreseeable future.

[NOTE: per the link in the parent comment, "Mozilla's 2019 expenses came to $495.3 million, or almost $5 million more than revenue."]

> This approach is prudent certainly, but challenging practically. In our case, it required difficult decisions with painful results. Regular annual pay increases, bonuses and other costs which increase from year-to-year as well as a continuing need to maintain a separate, substantial innovation fund, meant that we had to look for considerable savings across Mozilla as part of our 2020 planning and budgeting process. This process ultimately led us to the decision to reduce our workforce.

This looks like it's... getting there, but still too coarse-grained. It looks like those permissions are granted to the whole Deno process? So if your program needed both access to sensitive data on the filesystem and network access, and it used a malicious dependency, that dependency could take advantage of those permissions and exfiltrate that data.

I could be wrong, but I don't see any mention of permissions on imported code: https://deno.land/manual@v1.7.2/examples/import_export

Excellent questions with interesting answers. OP’s observation begins a fascinating discussion. I’ve been roughing out minimal cost of living, finding baseline around 5¢/hr; need to re-cast to kWh units.
Exactly. This is a Musk obsession project sold to the finance team on the potential to make money.

Feels very much like what happened with Overstock a few years ago with their CEO promoting it, deciding that they'd accept it, etc. Now he's gone full-nut, even more than Musk.

Agree, building this in 2021 is not a good use of data engineering time.

As well as the SaaS packages like Amplitude and Mixpanel, you also have great open-source tools and platforms for mobile and product analytics like PostHog (https://posthog.com/), Countly (https://count.ly/) and Snowplow (https://snowplowanalytics.com/).

No attempt at rational argument is made by you.

Argument irrelevant.
I feel the title is a bit baity. Most people would take 'being wrong about a social issue' as being on the wrong side though most of these are just about the order of the effect.
I kinda disagree with the implied notion here that it's necessarily the wrong choice to make. Part of public life and social interaction has moved online, and social norms are evolving to reflect some of that. Previously taboo subjects and lifestyles are now openly discussed and embraced. In the end, people just want to live their lives and want tools that help do that without interruptions or problems. Often, the truly disturbing realization for many is not that their information is out there but that people end up not caring as much about them as they thought they would. The scale of their insignificance hits them like a sledgehammer, where it previously just was a purely intellectual concept.

I don't mean to say that privacy is not an important goal. Surveillance capitalism as detailed by Zuboff and co. is one of the major problems the current young to semi-young generations will have to deal with. But it's not a case of enlightened vs. dumb but rather a different utility calculus.
that is scary - source?
> Value which cannot be stolen or debased.

Bitcoin's "intrinsic value" is really value unto itself for the most part, at this point in time. Maybe in the future it'll be used more as a currency, and we've seen that with Tesla, Bovada, etc., but I don't think most governments will allow such a threat to their currency without additional controls.

> Also, "blockchain" is just a data structure that has practically no use besides bitcoin.

I've always felt the other way around actually; I think blockchain will be used more widely and longer-term than Bitcoin. Blockchain as a technology has already been invested in and deployed by firms like IBM and JPMorgan.
Containers provide resource isolation using a shared kernel but are not intended to be used in hostile multitenancy scenarios.

A key feature of OS virtualisation is the strong segmentation boundary between

1. Guests

2. Guests and the hypervisor.

For this reason, VMs are seen to provide a stronger security boundary than containers and are used in preference where that aspect is critical owing to environment, multi-tenancy, business context.

Energy is the ultimate currency. A bitcoin transfer is cheap considering the amount of energy it takes, and its also cheaper then a bank transfer. Visa is overcharging if it takes such little energy.
>slow, costly and doesn’t solve real-word problems of identity verification, trust, reversible transactions, private transactions etc etc.

wtf are you talking about? I don't see any comments praising the author for writing the UI.
> But the issue is that Bitcoin isn’t supposed to provide subjective value, it’s supposed to provide objective value; it’s literally supposed to be money.

Money's value is also subjective, I'm not sure what you think is objective about it.

Sounds like you're just trying to dodge the comparison.
It does if there's demand for it.

And there's been growing demand for bitcoin for 12 years and counting.

It's deflationary by design. But by all means, stick to your government money.

> It would be useful (perhaps I will ask on m.d.s.policy) to know what the actual original order dates were for the 112 certificates in this list.

It'd be really fascinating to compare that with WHOIS data for the domains. That might show other misissuances - certificates issued for non-registered domains.
we think the demand has always been there, because busy people who are just out of reach of food hubs have to do a lot of work to access the great restaurants. (reservation, babysitter, train/uber cost, travel time, worried about getting home, etc)

at a society level, everything is moving into the home (movies, workouts) so we think diners would want to move nice dinners into the home too.

Layer 2 Solutions for Ethereum – How Do They Work?
Thank you for such a high quality comment.
It's misrepresentative to represent it just in quantities of number of on-chain transactions.

First, let's look at the actual transacted value: last 24h ~90 billion USD.

Then, consider the narrative of Bitcoin as a store of value - the value of Bitcoin depends on the security of the network, so this needs to be taken into consideration as well.

One estimate of the current market cap of Bitcoin is ~800 billion USD.

Then you also have all the things relying on and extending Bitcoin, without each unit of added value resulting in individual on-chain transactions. Take Lightning Network, for example. Uncountable (literally) number of transactions all enabled by the base layer of the Bitcoin blockchain, protected by its proof of work. It's only the entry- and exit-points that result in on-chain transactions.

Then there is also something untangible; the things bitcoin enables. Can you put a number in watts on how much is reasonable for the unknown number of individuals who have been able to remit money to their families that they otherwise would not have been able to? Those locked out of the global financial ecosystem just because they were born or are living in the "wrong" country?

If you personally find that those dimensions makes it more reasonable or not is up to you, but let's at least try to get a reasonable narrative.
So every developing nation steals technology, it's how they grow, the US did the same to the UK during the industrial revolution which is how the US got most of their textile technology. Most developed nations know this and somewhat look the other way while a nation is developing.

The modern problem is that China has hit the cusp of no longer being developing but rather is developed. Which changes the dynamic, the relationship and the expectations for what is allowed and how procedures will go. China seems to be trying to have their cake and eat it too though, they pad their numbers to look good but then decry when they are treated as if those are facts and they are held to a higher standard. It's like a middle aged man asking for leniency because "boys will be boys".
It makes adtech companies and things funded by ad revenue unviable to launch in California. Your local market is burdened by restrictions that can be complex or expensive to implement, and limit your profitability because you have less targeting data to give advertisers. Meanwhile your competitor in Texas has already shipped their app and is happily picking up customers in the other 49 states, word is spreading, and they're raking in money from their additional targeting and from lower taxes.

I think the CCPA is important and good for consumers, but claiming it has no effect on business is a non-starter. It has basically no effect on businesses that don't rely on ad revenue, though.
Safe Haskell is one in this vein (it's lower level and you would apply a capability layer on top), although like other past efforts on this front it's mostly languished in obscurity even among the Haskell community and is used by very few people.

Most people cannot agree on even simple and straightforward issues due to any number of reasons ranging from capacity for change, political alignment, or what their favorite news anchor told them to do

This is not true, most people don't really care. They might have a team they root for, but even those seemingly braindead people that are posting on the internet towing their party line are just looking for a way to fit in. They are all capable of thinking for themselves, and most of them will have a reasonable conversation with you if you run into them in the real world.

Seriously all I am saying is that regulation should be slow to change, and be approved by elected officials. I also think there should be way more congressional districts, and senators. Currently there is way too small of a sample size to be representative of the population. Basically I'm in favor of more democracy not less. Honestly if it wasn't such a waste of time I would be ok with replacing congress with open voting on every issue.
I did not write this as a defense of keeping the monarchy around just for the curiosity value, or from the raking-in-cash angle, just highlighting that the experience is quite different for visitors.
450kg of CO2 per Bitcoin transaction? That seems like a lot indeed.
FYI, hydropower has a fixed capacity due to obvious limitations, namely viable rivers to dam up. There is basically no option for hydro expansion left on earth. In that light, I think the "sustainable mining" argument is pretty flawed. We can't scale hydro- and geothermal power, but we need it for base load in a sustainable future. It's the worst energy resource to occupy.
I'm still not sure if he can read or not.
Yeah that part is a little vague in the copy.
Well, the owner of 51% of processing decides. It also has no use if both parties aren't connected to the internet. Also, you are in the truest sense not the owner of the bitcoins. You are using the "ownership service" of the network. If the network goes down, you lose access to the network (goverment internet filtering) or the network gets taken over, you lose everything. It's strictly worse than gold. The only downside of gold compared to this is that gold has to be physically stored somewhere
I've always wondered what the cost for HDCP encryption on our media wastes.
Some developers are fearful of writing original code. Others realize it's not going to be appreciated by their colleagues to write their own package manager to solve a problem most of the industry disregards. Imagine arguing for getting the "write our own package manager to replace npm/yarn/pip" ticket into a sprint.
Some of the following applies more to chains with smart contracts, rather than Bitcoin itself, but:

> refunds when corporations rip us off?

Easily implemented in various ways. One old scheme is a simple 2-of-3 multisig, where the keys are buyer, seller, and arbitrator. If buyer and seller agree, the arb doesn't have to be involved, otherwise the arb decides where the funds go.

> Who enforces splitting of equity when some rich dick beats his wife into submission? The courts don't control any bitcoin keys.

No, but courts have effective ways to make you pay up even when they don't directly control your funds, including putting you in jail for contempt.

> my children would not be able to trade fiat for it

If Bitcoin or whatever isn't available to anyone besides miners, then I don't see why it would have any value at all. Cryptocurrency that succeeds is out in the economy, not locked up in a small group of professionals. There are plenty of cryptocurrencies owned only by a small group of enthusiasts, and they are nearly worthless.
The greed is the chairs of central banks and the policymakers who are debasing other monies (some people benefit more than others from this).

If they weren't debasing other people's hard earned value, there would be no need for bitcoin.

But since they are, and are doing it at an increasing pace, the demand for bitcoin is inevitable.
Responding to your edit, yes, we do provide a simple way to evaluate the mask's safety on your person; a negative pressure test: https://narwallmask.com/pages/usage-guide#h:negative-pressur...

This makes it easy to tell that you have a complete seal.

The fact that your existing masks do not pass without tape indicates that you do not have a seal, and the filtration numbers you're seeing are reduced by many percentage points (eg; from 95% to 90% or lower) as air enters the mask unfiltered through the sides.

I have not performed the cigarette test myself, and haven't seen information indicating it is a reliable covid test, but you are certainly welcome to try it with a Narwall! I'd be keen for your results, and could provide a discount in exchange for the information.

It might be not so much the proof of C++ deficiency as simply another manifestation of mismanagement of the browser development by
Mozilla Foundation.

Because nobody ever wrote concurrent systems in C++?
Yeah that's true. In this case I think it's the pragmatic approach to not stifle the space industry when there's so much we could be doing (and aren't) elsewhere, but we do definitely have to sort this problem before it becomes a big one.

Maybe governments legislating a sliding scale of regulation or cap here would be a good idea? Like, nothing to do now, but as the industry or any one company grows in this way, regulation or emissions caps grow in that way.

I'm not familiar enough with Java to have a strong opinion on this, but this HN comment from the linked article mentions that you can only have one SecurityManager per app, so sounds like that's still too coarse-grained: https://news.ycombinator.com/item?id=18599365
Basically your argument is, "Bitcoin may not incentivize improvements in energy efficiency, so we should scrap Bitcoin and use something more efficient." Great, let's do it. The technology is already here, in fact, the technology was always there. Have a consortium of banks operate a distributed public ledger. The banks will charge fees to include transactions on the ledger, just like miners charge fees now, and the economic incentives to raise or lower fees will be similar -- but the fees will be lower because the consortium members will not need to cover the electricity cost of mining, only the cost of operating their servers.

The only problem Bitcoin mining solves is the lack of identification among the miners (i.e. the "Sybil attack" problem). Seems pretty obvious to solve the problem by introducing identity, particularly given that the large miners / mining pools are not really anonymous. Sacrifice the small miners who contribute little to the system, set up a consortium, and enjoy whatever benefits the distributed ledger provide without the waste.

(Yes I know, banks are evil, how dare anyone suggest that we acknowledge any authorities in a system, why should we trust the banks, etc.)
I think the inherent complexity of, e.g. environmental regulation is such that it's impossible to write them in a way that is both effective and straightforward enough to be widely understood, much less widely agreed on. Inflexibility also works against effectiveness in cases where the law must adjust rapidly to changing conditions. While the US hasn't implemented it terribly well, I think the executive agency model is potentially a good one.

A bird detection system such as this (less so species detection and more so avian detection) would be very useful at airports where bird strikes are quite common, and where humans are regularly used to sight for birds near/around runway approaches.

I’m surprised to see they're not marketing towards the aviation (no pun intended) industry too.
You're right, that wasn't a very good argument.

But the point is that saying that "it has intrinsic value" doesn't really mean anything if one cannot even given an order of magnitude of what it is.

I won't say that the price of gold is directly related to its intrinsic value (there is no way to do "financial valuation" on it) but the situation with bitcoin is even worse. At least there are some industrial uses of gold that can be used to assign an objective value to an ounce of the metal.
Not necessarily. The concern was "because it’s not web-based", which could mean that they don't like the web UI or the web based technology stack behind it.

For me a native app has to both look and feel native. An app that looks like a native app (Like an Electron app can) isn't fully native for me because it still runs a web browser under the hood.
Cannot be debased? When the US government rules it illegal, or enough people collectively lose interest, btc will no longer have value.
My point is it's easier to gamble when you have corporate tax advantages.

These are rich people/companies putting non-existential amounts of money into something new in the off chance it pays off. Best case scenario they get even richer, worse case scenario they pay a lot less in taxes. Either way their lifestyle/needs will be met and the business will continue.

For the average individual: Best case scenario they get rich. Worst case scenario their investment goes to zero or close to it and they get a max 3k tax deduction on their taxable income. Their lifestyle/future savings could be greatly impacted by the loss, certainly far more than the businesses/rich people in question would suffer.
According to the article, in this case, the customer is loyal to AT&T, who only offers 3MBps, where other competitors in the area offer up to 200. He should probably just switch to a competitor. It's not like they're going to suddenly decide to offer high speed internet in his area because of the stunt. They likely have no plans to, despite saying they're "working on it".

That is not true. For example I hold bitcoin. But I also don't believe that bitcoin will replace the financial system or will serve any real purpose in the future.
I am just speculating on its value.

People speculate on loads of assets which have no real life utility. For example, art or classic cars.
I'm not sure what skills you consider necessary to win both a contested primary election and a national election, but I'd consider many of them intellectual skills and the competition to be of a high level.
The vast majority of games are indeed developed in other languages than C++. The native languages of the most widely used game platforms are C# for anything done with Unity, Java/Kotlin for Android, and Swift/Objective-C for iOS.

The C ABI is the lingua franca still, you can call it from all of the above. And you can expose a C ABI for your Rust library.
I canceled the return and looked at the Amazon app again. There is no option resembling "incomplete delivery" in my case. It looks like if you ordered only one item they assume you got something and they want it back before issuing a refund or replacement.
