Big fan of that one, been using it for years.

They published this in Popular Mechanics in 1912, we've been ignoring this for a long time:

The furnaces of the world are now burning about 2,000,000,000 tons of coal a year,” the article reads. “When this is burned, uniting with oxygen, it adds about 7,000,000,000 tons of carbon dioxide to the atmosphere yearly. This tends to make the air a more effective blanket for the earth and to raise its temperature. The effect may be considerable in a few centuries.

Also, this Wikipedia article has a good summary on the overall arc of our understanding: https://en.wikipedia.org/wiki/History_of_climate_change_science

The app, in the scenario where we're trusting the author/store, is only part of the surface to the extent it's exposed to a potentially malicious payload. eg. a trusted solitaire game using a vulnerable API doesn't exacerbate that vulnerability because it doesn't expose it to untrusted input whereas a PDF viewer would because the PDF could be coming from anywhere...

Really appreciate you taking the time to write that. I have a sense of most of that ("defense in depth" and "threat model" are good lenses to think about such things through for sure!) but what I was trying to get a better grasp on was how much risk from automated attack was a normal person without worries of an "advanced persistent threat" taking on by using a device past EOL. Like you say, "Quantifying how much of a difference it makes is not trivial" so I feel less conflicted to know that you're comfortable with your dad taking that risk.

I would think that the main thing at stake for a typical user isn't just browsing history or email though but rather identity theft since a successful attacker can use the device to get through 2FA.

I don’t think they are things that can be fixed on the app level?

Indeed not. So I'm trying to better understand how vulnerabilities at the system level are exploited. It seems like the attack surface is limited to RF (bluetooth/wifi can be turned off if one is willing to make that compromise), app install (many just use a small selection of well-trusted apps), and messaging/browser which are regularly updated if the device is properly configured.

Based on this thread I'm beginning to form the opinion that it is not unreasonably foolhardy for someone to continue to use an unsupported device if they are willing to make the compromises necessary to limit their attack surface.

Thanks, that's encouraging and very relevant. Looks like it was introduced in Android 10 and aside from "Project Mainline" is referred to as "modular system components": https://source.android.com/docs/core/ota/modular-system

Can you shed more light on what someone would be risking by continuing to use an EOL device? You say you don't advise it, but it'd be helpful to elaborate on why.

It seems like the increased vulnerability would be relatively limited: I presume the browser and messaging are by far the most common vectors and those would be as up to date as ever but I can see how exploiting an unpatched vuln there on an unsupported device could have more impact as it would give more options for privilege escalation.

Otherwise it'd be something RF based. Aside from widely publicised things like BlueBorne (that we should be keeping an eye out for anyway), is it a reasonable concern that there are identify theft rings employing people with modified hardware wandering around subway systems trying to exfiltrate credentials from devices with specific vulnerable basebands? Seems like Android also offers some defence in depth there that'd make it unlikely enough to ensure it wouldn't be worth their while?

There are a few technologically disinterested people in my life that I advise (as is no doubt the case for many here) and I don't know how strongly to push for them to get new devices once theirs fall out of support. Most of them are quite content with what they're using and are not in the habit of installing apps (and will reliably ask me first) so they really would be replacing the device solely for the updates. In some cases it's not only the time and effort to decide on a replacement and get things transferred over but the expense can also be a burden. So I don't want to raise the alarm lightly.

Good point! And ya, when I open umatrix on a comment thread I see a whole menagerie of instances serving me images as I guess that goes for the profile image too.

But I find that somehow less concerning as they just know "someone at this IP viewed this thread containing these images" than "the user at this IP wrote this comment (or post)".

Hmmm, but if DMs allow images and they work like this, a user with their own instance who wants to know which IP wrote a comment could perhaps send a message to the author with a unique image...

I've enjoyed runbox.com for years but don't think they offer catch-all, at least not when I last checked. You might look at mxroute.com, I heard about it later and might have gone with them first and they somehow seem more likely to support that

Just because we want thoughtful regulation does not mean we support Meta and Alphabet. Why is this fascinating or surprising? Do you think the EFF is a huge fan of link taxes or Facebook?

It's not the only IXP, just the largest.

It's not really any particular problem, I just think it's the sort of thing that's worth being aware of at least. So I pointed it out. I did overhype the headline (should have put the building housing a key part...) but did indicate in the post that they bought the building and not control of TorIX itself and that

While that’s not necessarily an issue, I kinda figured it was at least a little bit notable but I’ve not seen it mentioned aside from an investment context.

It was also an opportunity to highlight Bell's unnecessary sending of traffic through the US which I think should have a higher profile though I'm not a strident nationalist and might actually be sorta okay with it if it was actually legit more efficient or something but it sounds like it's done for business reasons eg. to pressure smaller players into private peering.

I'd like to see infrastructure have a higher profile in general. I really appreciate connectivity, electricity, running water, roads, etc. and thing the investments we make there pay off. But it seems to often fall prey to being easily underfunded in favour of some attention grabbing but ultimately underwhelming pet project calculated to garner votes. Like tech debt being swept under the rug in favour of shiny features.

It's just the building, seems fine really but like, maybe less of a non-event than the almost no attention it appears to be getting.

Or you mean the part where Bell unnecessarily routes Canadian traffic through the US just cause they can get paid more that way? Ya that doesn't seem good to me either but has been widely known for years now and apparently we're okay with it.

True, I do value public broadcasting and support it through my taxes so ya, CBC and TVO. I was mostly just thinking of things I had to opt into paying and brought that up in the larger context that you don't need a state or a massive corporation to produce quality journalism. And so if our state fails to extract a bailout from American tech companies to satiate our bloated media corps I'm pretty confident we'll be okay.
