Slow speed turning wears tires hard and unevenly. Like geologic erosion, such wear can promote and accelerate more cutting.


All these failures help progress the industry. Lessons learned are a gift


I work for a O&G super major. You’d think that one of these groups would be more interested right? It’s all about money, if one can’t make huge profits (especially with huge gov subsidies) then they will continue to ignore the prospect. Megacorps aren’t trying to save the world they are trying to get mega rich.


Wait until they see what happens when all of their exploitable employees get cooked lol.


Clean air is default. You can’t make ‘more clean’ air to offset dirty air. You can just hide real and compound health impacts with the fact that someone else exercises more in clean air and lives better.


No, air isn't clean by default. All air has particulates in it at various levels. There are natural particulates like forest fire smoke, blowing dust, and volcano emissions. And there are man-made particulates, dating back to the invention of fire but getting much worse with coal. All are harmful to some extent.

If you do something that causes air in one place to get 1 ppm dirtier and air in another place to get 1 ppm cleaner, and the populations are the same, the net impact on health cancels out.


> If you do something that causes air in one place to get 1 ppm dirtier and air in another place to get 1 ppm cleaner, and the populations are the same, the net impact on health cancels out.

The average ppm cancel out but the outcomes don't, because you have more sick people: Let's say 12 ppm is the maximum safe ratio for some pollution [edit: assuming it is a pollutant that has local impact, not like CO2 which has global impact]:

1) If place A has 10 ppm and place B has 10 ppm, then nobody is sick

2) If place A has 15 ppm and place B has 5 ppm, then people in place A are sick

Public policy generally doesn't work well with averages and similar analyses, because outcomes are usually discrete for each individual; it's not a stew where you can mix outcomes together and get something good.

As another example, if the economy results in one person making $1 billion and 999,999 making nothing, the average is $1 million per person - but what does that mean? 999,999 people are still in dire poverty. (It does have some significance, for things society does collectively - fund police and fire, and even help for poor people.)


Health effects of particulates are approximately linear. So the more particulates the more mortality. There's no threshold below which people are healthy and above which they're sick.

It's actually slightly sub-linear, meaning that an increase for one group and an equal decrease for another group produces slightly less total mortality. See https://pmc.ncbi.nlm.nih.gov/articles/PMC9109601/#gh2329-bib... for some numerically fitted curves (search for GEMM).


> If you do something that causes air in one place to get 1 ppm dirtier and air in another place to get 1 ppm cleaner, and the populations are the same, the net impact on health cancels out.

Not exactly. The other place might have people die from poverty, illnesses and godknowswhat much earlier so the effect of pollution shifting doesn't manifest itself or even gets masked off by rising life expectancies in general - that's the dirty secret behind the move of dirty and toxic productions to Asia.


The marginal health impact of 1 ppm (of what?) may not be the same across all concentrations, not least because of adaptive behaviors: avoiding outside exercise, using air filters.

But in general I agree that you should be able to look at tradeoffs of a set of actions and allow of the possibility that some negatives are offset by positives.


This article only discusses image generation, a small subset of AI use cases. As users, governments, corporations, and background processes grow to consume AI all day the water and power issues will grow the same. Whether AI or JavaScript, action is needed ahead of shareholder value.


What water issues?


Maybe they mean the water cooling systems used in the data centers. As far as I remember, it was a closed system so I don't know if that's significant.


Of course they're a closed system. Why wouldn't they be?


Water needed for the power generation and onsite cooling seems to be the higher risk and impact. Aquifer depletion has real and permanent impacts to the community.


While some of the article’s leading point in apps doesn’t clearly connected to collusion to raise egg prices, it’s all valid. Tearing it all down is sore of you.


The era of trump will accelerate this further. Not that Obama Biden were saviors, Trump and co are putting fuel on the fire


Almost too many steps to remember here. Would it be possible for an app to prompt you to do all this? An app can bring up settings to allow your camera access, why not to quickly change those other settings?


What apps do you recommend with p2p messaging?


Lots of groups have used https://briarproject.org/ successfully in the past, I've heard. Assumes you're using Android though which if you're using a burner, you most likely are.

Successfully in terms of communication or in terms of security?

Successful communication is easy if you don't worry about security. Just post it on Instagram.

How do you know if your security is successful? How do you know if your messages were intercepted and read, your app was hacked, data was extracted from it, etc.? The attackers (authorities or otherwise) are not going to tell you.


I’d go as far as to assume there’s no evading surveillance in a strict sense.

If you attend, leave your phone home (atypical usage), go with other people / meet them there / other people you know are there (facial recognition / gait analysis / clothing preference) those are all good data points to predict with high probability where you are and what you’re up to, especially given your typical movements, data usage patterns, purchasing habits, friends / acquaintances / social media interactions are all in at least a few databases.

Take the security measures you’re willing to make the tradeoffs for.

If history is anything to go by, we’re only ever an election, or other political churn, away from your particular sets of beliefs / identifiers being persecuted, or at least your least favourite political prisoners being released and coming after you.

And, as you allude to, relying on the security practices of others has its own problems. Even Perfect Forward Secrecy etc etc provides little help against Rubber Hose Cryptography.


>If history is anything to go by, we’re only ever an election, or other political churn, away from your particular sets of beliefs / identifiers being persecuted, or at least your least favourite political prisoners being released and coming after you.

it goes other way around too - you are only one election cycle away to be pardoned.

And if the protest is succrssfull, you dont need a pardon anyway.

Being pardoned doesn't help much if you're dead.

A special law shields you? How does a law shield you from persecution?

We won, this is how.

There is an escalation ladder you need to climb to attain martyrdom. It takes effort and courage and not everybody can or should do it. It's okay to be on the part of the process that provides moral support to the more hardcore participants.


It’s not clear to me what you’re getting at here.


Sometimes, when a protest makes the government extra uncomfortable, they'll shut off the internet. So it's probably best to not rely on Instagram.


> Successful communication is easy if you don't worry about security. Just post it on Instagram.

Nope, assume Meta is captured and will suppress such communication.

This has been widely replicated on inauguration day before being rolled back.

I would assume any social media site whose CEO attended is captured as well.


Here's a guide to PET (peer-to-peer, encrypted, through Tor) apps, focussing on Briar and Cwtch: https://itsgoingdown.org/the-guide-to-peer-to-peer-encryptio...


Depending upon which OS are on. If Android - Briar is the most famous and obvious choice. On iOS? There are not any options really but wasn't any usable one around a year back the last I had checked.

On iOS there are not many options for P2P w/o Internet (I assume that is what you meant - otherwise if you want P2P over Internet then there are some options although not really "truly" P2P of course - and of course if Internet is shut down or overwhelmed then it will be down). There's https://github.com/berty/berty (the last time I tried it was crashing incessantly but it might have improved). I do not know of anything else really (there might be few but I am not sure).
