My experience is that visuals help people _feel_ like they understand the concept, but the equations are necessary to get an _operational_ knowledge.

It's all well and good to be able to talk about the "deepest human knowledge" at a dinner party, but it doesn't help you solve actual problems using the fourier transform.
Not only is it an incumbent switching to another architecture; it's an incumbent switching to another incumbent architecture. ARM is older than PowerPC and almost as old as the Macintosh itself; it came out in 1985.
I was making a general argument for improving security at all levels and the few examples that I gave were not meant to be an exhaustive list, in case that was not obvious.

As for outlawing cryptocurrency, that's a very narrow minded approach and it's very similar to banning encryption because criminals use it to evade law enforcement. Crypto asset networks are protocols so don't expect applications to produce end user value over night, just like TCP and HTTP didn't produce value over night.
Did you read the thread?

He’s decrying regulatory impotence, not calling for a knee jerk ban.
I get that this is a problem, but comparing it to oil as being the better alternative is not convincing: oil have been at the center of terrible wars, corruptions and ecological disasters for decades. Entire populations have been displaced, robbed, poisoned, conned and/or killed for oil. Let's not pretend it comes with less suffering attached, not to mention we had almost a century to improve the process, and we are comparing it to electrical cars, something that had been barely marketable to the public for 10 years.
It could be because they started as a Windows only product, then they produced a Linux version, and finally the Mac version.

I have only used the Windows/Linux versions. By the way, with one license you can use all 3 platforms.

I actually use the Portable Windows version, for when the company I work for won't allow me to install software :)
If you want evidence then all you need to look at is the extremely low adoption rate. Even developers often prefer MacOS. My statement about Linux's awfulness included an opinion qualifying phrase, theirs did not. Why do I need evidence for a subjective opinion? Besides, I know from experience that if I air my grievances with the Linux Desktop an army will come out of the woodwork to tell me how wrong I am, attacking my intellect, my use-cases, the very facts of my experiences, etc. If you need evidence I suggest you do even the tiniest amount of looking at how negative opinions of Linux Desktop are treated in forums. I, for one, am not even remotely surprised to be downvoted steadily every time I express them.

> Rather, what people in this thread have been trying to get across (I think) is that we like Linux the way it is.

And that is fine, I don't want to harass people who use and like Linux any more than I want to be harassed for not using. What I want is to not have to keep having the same arguments over and over about why I feel the way I do about it, because the community has made it clear they don't care.

> We think it's "pretty great".

IF parent had said "I disagree, I think it is pretty great" we wouldn't be having this conversation.
that's deployment.

yocto only has half baked support for a binary layers, let alone binary sdk layers, where you add more packages, for the target or the build host, and more layers come further down.

this is for you to use the binary packages to build your images. which you then deploy, as you suggest.

key thing: you use suse/ubuntu/redhat binary packages to build and create your add-ons which you then deploy, as image-on-the-fly (created on target during traditional Linux install/update), or as precooked image (qemu, container or, new: embedded flash image)
What’s the difference between this and Twitter mobs?
Sure, and the 401K would be a better safety net. If the government opened up a 401K account for every retiring person, the result would be better.

This is the tweet that ties the rise of ransomware to crypto anonymity:

1) Receive ETH tied to crime

2) Send to tornado.cash

3) Withdraw from tornado.cash

4) Now you have clean ETH in a fresh wallet not tied to identity

5) Use a DeFi non-KYC exchange to swap for another token

6) Use KYC exchange to swap token for dollars/euros

If so, what can the US government do to prevent anonymization?

Ask HN: What does the Police mean to you?
Where I grew up, there was a very obvious split in sides. There were a lot of white police officers, but also a lot of minorities around including my family. To me, a Police Officer is like a pothole in the road, I try to avoid it. I (personally) don't like them because of what I saw growing up (shootings and violence) but I would like to hear other perspectives. What does the Police mean to you?

Why are you framing this as being a particular problem for electric cars and wind farms? It sounds like a problem that encompasses all of global trade, manufacturing and modern technology.
I did, he's talking about how bad cryptocurrency is for the entire thread, and then the last sentence says "regulatory impotence". I'm not convinced.
You might want to call it a scandal, if you want to find reasons of being opossed to regenerative energies in general.

Otherwise it is a mere technical problem calling for a better solution than what is avaiable right now.
An increasing amount of people I know don't have a TV screen and show no interest in getting one. They just use computer screens to watch instead. Not that that's better for privacy since they've at the same time been switching from physical discs to online data-harvesting services like Netflix. So they're really just building DIY smart TV's.
Wait, wasn't the recycling of those already counted in the cost benefits of electric cars?

> cryptocurrency is pretty much worthless to use as currency.

I agree. I used to think that this would decrease its value, but that hasn’t happened.

There are crypto pegged to specific currencies, like USD, but the transaction fees are so high that it’s still not useful to use as currency unless I have lots of really high transaction values.

I don’t have crypto holdings but, for example, since Tether is traded on ethereum there’s a $21[0] fee for any transaction.

This may be worse than the fluctuation problem since a $21 fee on any purchases wouldn’t work for me. Comparing the fees on using a check or cash, this sucks.

I suppose this gets competitive with visa/MC, if I assume a 3% fee, around $700.

I did it. I was a front-end developer at an agency. I took Monday off to be with my daughter before she started school. Later on I cut my hours even further and took on the bulk of the housework, childcare, cooking, shopping, etc. I’m fortunate in that my wife has a career she loves, and excels at, so we don’t really want as long as we are on top of our spending. Which I have time to manage. It has been the best thing for our family.

Constant-Time Big Numbers: An Introduction
I don't think anyone has been prosecuted. I'm not arguing with your point - this stuff is messy. It's not clear cut. There's a combination of how the law is written, how courts have interpreted that in the past, whether that would stand up to the supreme court or the EU courts, and what you can persuade the jury and judges to believe.

If you're providing part of your password you run the risk that

i) you'll be convicted of the S53 RIPA offence (potentially 2 years for most stuff, potentially 5 years for child sexual exploitation or terrorism)

and

ii) they'll decrypt it somehow and you'll also be convicted of the original offences.

Criminals are well aware of the trade-offs of the English courts. Do you plead guilty at the earliest opportunity (and get a reduction in sentence as a result) or do you wait until the day of the trial (because many trials collapse before they get to court).
> Even if you opt into those (and the projects I've been involved with have), the precedent is established: when new compiler optimizations are introduced with disruptive semantics, they are opt-out, not opt-in — a fail-dangerous failure mode.

Actually, the default for gcc is -O0. You are opting in with -O2 etc.
The reason why cryptocurrency has the benefits it does is that it is highly impervious to third party intervention, whether that intervention is repressive regulation (which by the way, I would count KYC/AML laws as, after experiencing the financial exclusion and privacy violation it causes), benevolent regulation or just some party seeking to engage in rent-seeking, as in the case of a company with a locked in customer base raising fees to above what is economically optimal.

The only way to eliminate its negative effects is to obviate its core properties of permissionless-ness and decentralization.
No, it rarely works but FOMO is the worst with marketing people. Have been doing it 10 years now and I still refused to accept pop-ups as anything useful.
Thanks mate for sharing. Nothing too crazy is wise in long term. Keep it up :)
All right, welcome your ransomware organized crime overlords then. BTW, I've never seen cryptocurrencies used for ANYTHING good yet.

It's about hiring hitmen, buying drugs, buying child porn, stealing wallets from naive fools, stealing power by illegally hooking hidden mining centers to the grid, stealing power through mining malware, and so on and so on.

Crypto is a pyramid scheme for idiots, and on top of those idiots is propped up an entire ecosystem of illegal activity.

Since we already have enough currencies in the world, and decentralization only means theft can't be stopped at all and regulated, I'd say this mythical "value" of coins will never happen. The use case for regular law-abiding citizens buying shit online is already addressed. The use case for regular law-abiding companies doing large financial & asset transactions is also already addressed.

What wasn't addressed is anonymous cash transactions for criminals online, and that's what coins addressed. We don't need that.
The batteries will have a second life even after they're completely useless for cars. They can be used as grid storage for solar power. The Duck Curve makes such batteries valuable even when they're not very efficient. Poor capacity/weight ratio doesn't matter when they are sitting on the ground.
Not necessarily comparable for purposes of global heating effect (not sure if that's what you're doing or not).

The CO2 that a human exhales is from the carbon in the food they consume. That carbon ultimately comes (whether indirectly via animals or not) from plants, which drew that CO2 out of the air directly, typically at most a few years prior. The net change in CO2 concentration is zero.

Contrast this to burning fossil fuels which moves carbon from places where it is not enhancing the greenhouse effect (e.g. it's in coal, gas wells or crude oil) into the atmosphere where it will cause global heating - a net increase in CO2 concentration.

As a side note, methane produced by livestock or food waste does still have a global heating effect as CH4 is a more "potent" greenhouse gas than CO2, so there is a net increase in heating potential due to this conversion.
For some reason I was expecting to read how belugas were catapulted over borders.
All those points are true - though I'd argue this is stretching the "one app per VM" thing -, but I guess this is just the usual case of understanding your situation and realizing there's no one size fits all.

My take on this question is rather that there shouldn't be any dogma around this, such as disabling mitigations should not be considered absolutely, 100% harmful and never, ever, ever disabled.

In the context of the OP, where the application is running on AWS, backups, email, etc are all likely to be handled either externally (say EBS snapshots) in which case there's no issue, or via "trusting the machine", so getting credentials via the instance role which every process on the VM can do, so no need for privilege escalation.

So I guess if you trust EC2 or Task roles or similar (not familiar with EKS) to access sensitive data and only run a "single" application, there's likely little to no reason to use the mitigations.

But, yeah, if you're running an application with multiple components, each in their own processes and don't use instance roles for sensitive access, maybe leave them on. Also, maybe, this means you're not running a single app per vm?
>>I'll keep my very efficient Audi diesel car (79g/km CO2)

The thing is, we realized some time ago that CO2 emissions are not all that matters in a car, and your diesel is spewing very harmful NOx emissions whever you drive, plus if you haven't got a DPF(I don't know how old your car is) the amount of fine particulate matter that is proven to be dangerous to health is quite high as well.
I wonder what happens to the used car market. When the battery is pretty much borked a used car is of no use. And replacing the battery would be way too expensive for many people who rely on used cars.
Is the energy required to ride a bike somehow free? How do you ride a bike for hundreds of kilometers?

> People that really care about the environment ride a bike. They don't buy an electric car and try to justify the currently unknown long term environmental consequences of their purchase as somehow being better than the known consequences of gasoline and diesel cars.

This is so much false dichotomy that I'm having trouble assuming good faith.
That was an awesome story! Fairly classic trope.

I had never heard of him. The story reminds me a bit of the old Tim Hutton movie Turk 182.
Its not a scandal yet!

Because we are approaching a cliff when a lot of 1st and 2nd generation wind turbines are about to be decommissioned or refurbished.

Note: this is for Scotland.

Its bad enough a single wind turbine blade requiring a convoy escort along small winding roads for installation. Now they have to do the same and dispose them.

The cost is going to have to be paid somewhere, most likely by consumers.

Or they will be disposed off cheaply in a bad way.
Who cares? It's GREEN($)!

Please people, it is just another industry within consumer capitalism. They externalize all the nasty bits so all the dopes can feel good about driving a Tesla.
Do fiberglass degrade to a point it can't be recycled? We already use it for multiple things, from boats to PCBs, so there would be quite a big market. Any reasons why it shouldn't or couldn't be recycled?
> the criminals had very few options by which to extort money from their victims.

I remember the phone dialers in the 90s. Malware would also steal your credit card, social security etc. Identity theft was and still is rampant why try to extort £1000 from you when I can just open a new credit card in your name with a £3000 limit and spend it all before you know its a thing.

Most people who fall for these scams are elderly people who wouldn't know how to buy a bitcoin to pay a ransom. The only people that pay ransom ware are large organisations that have the funds and ability to defend themselves but choose to invest in insurance over security.

> Thus the scale of the number of people you'd have to exploit to make this profitable is enormous.

You mean they need to find a 0-day and then write a worm? I think this is already being done to steal millions of credit cards.

> however that requires that hackers hand over the routing information to their bank account

They use the bank accounts of their victims to hide from authorities and like I said they have millions of accounts.

I think the rise in ransomware since the 90s is closer correlated to how much people value their data / technology.
I heard someone say that to run all the cars in the US on electricity would require building a new nuclear power plant something like every week for the next 10 or 15 years. Is this true? I think this is completely unacceptable. The risks of nuclear accident are too great. The competence required to safely operate nuclear power plants is a limited and possibly dwindling resource.
The author throws in
"and a big asterisk on the naive notion that nothing escapes black holes."

Not true. The jets are from the plasma surrounding the black hole. And we see that already, meaning photons escape it all the time. Since the jets didn't start below the event horizon, they were never "in the black hole" at all?
You are misunderstanding the nature of the problem and how it arises in any system that uses multiple entities to represent real-world entities.
Emacsclient is instant on any hardware I ever tried since the early 90s. I don’t understand why people differentiate below the 100ms level.
Increasing the energy usage of our species is not "irresponsible" or "malicious". Every technological improvement increases the energy usage of our species. I think that is the point they are making, that it is wrong to say that using energy is strictly a bad thing.

If you want to decrease fossil fuel consumption then you should be crusading for worldwide carbon taxes, not bans on new technologies.
Yeah, the mafia cares about EU regulations. Or so I've heard...
>Is it too hard to think we can do something like that for the huge card batteries which are much less disposable than the lead acid ones?

Who is we? I don't remember being able to vote for any politicians that are interested in this sort of thing.

Hydrogen cell cars are probably the best option for the future. It's very abundant naturally and its byproduct is H2O. We have to figure out how to mass produce it though.

No, not really.

Paintings aren’t used as currency, they are used as assets or stores of value.

Similarly, diamonds are pretty rarely used to actually transact and are rather just asset stores. It goes cash->diamond->cash; not cash->diamond->something else.

Anything can be traded or bartered that doesn’t make it currency. Some cultures used beads and shells and stuff but don’t any more. That doesn’t make beads currency.
Yeah, all his plans took a lot of work, and that one is a serious amount of technology.
Indeed that's another way of doing it, quite elegant, too.

Wasm is not basically assembler, it's (going to be) very high level:

- https://github.com/WebAssembly/reference-types

- https://github.com/webassembly/threads

- https://github.com/WebAssembly/exception-handling

- https://github.com/WebAssembly/function-references

- https://github.com/WebAssembly/gc

Though it is true that the original MVP was very barebone and could be compared to assembler. However, the reference types proposal has been shipped in all major browsers and is considered "finished".
Maybe I'm weird, but I don't usually close VS Code, so this isn't an issue for me.
For personal use yes, for professional use the "tax" is either absent or doesn't matter in the grand scheme of things. Considering I have plenty of "disposed" used UPS batteries laying around I'm pretty sure companies don't care. (This is in the EU)
I think there is money in using modern robotics for automatic recycling of batteries. There are millions of cars but probably only hundreds of battery module types in the coming decades. So certifying a recycling algorithm for a new module type shouldn't be a difficult task, and wouldn't require retooling.
Is it possible to split with CSS so that when copied it won't have spaces?
There's empirical evidence, loads of it, that this simply isn't true.

Syntax absolutely does matter, in all walks of life, not just programming.

We're not infinite, error-free computers like some sort of mathematical abstraction. We have squishy meat brains evolved to tell stories around a campfire.

As a random example: I learned Rust just for fun, and something that repeatedly caused hours of frustration is that unlike every other modern language, it allows identifier shadowing. This compiles and runs just fine:

let a = 5;
let a = "wat?"

Practically no other language allows this, because it is a recipe for errors.

Internally, compilers typically use single static assignment, so the above would be processed something like this:

let a_1 = 5;
let a_2 = "wat"

For a compiler to track this is no problem. For a human? It's a problem. Maybe not for trivial examples like this, but if dozens of identifiers are littered across a huge function it can be a challenge to keep track of which one is which if the names are the same but they're... not the same. Especially if the change is subtle.

We're not computers, that's why we make them out of silicon and metal and sell them for money.
You can prove it in the context of Ergodic theory. Though that's a model so assuming that it correctly approximates the real world is still an assumption.
Also the pollution that is created to make the batteries and also to generate the additional electricity demand on coal power plants to charge all the cars.

Auto makers are just selling the feeling of doing something good for the environment to consumers because that’s what is in vogue.
