One thing that would be useful to understand is the distinction between CMR and SMR

I got a nice deal on the x280 and am happy with it, was also looking at the various X1 carbon. Two criteria I had were I wanted USB-C charging (since I have those chargers around and they can handle these laptops) and a single battery (eg. the T470s I have from work is nice but it has two small capacity batteries that each cost the same to replace as the full size single ones in the carbon and x280). One thing to keep in mind is some of the earlier X1 carbon don't support NVME SSD (I think it started with 5th gen?)

Edit: another thing to consider is soldered RAM. Part of why my x280 was cheap was it's only 8gb and can't be upgraded. Since you're looking at lighter weight things and using FOSS (and perhaps open to tinkering with things like ZRAM) that might be a useful aspect to focus on because there is probably a glut of such machines given how memory inefficient things are lately with every trivial app running a whole browser engine. OTOH, depending how many tabs you tend to have open and how many electron apps you tend to keep floating around, 8gb might start to feel cramped. Especially if you think you might want some VMs around.

Next time I look for a small laptop to have handy one thing I'm going to be sure to prioritise is: how much battery does it use while suspended? I'd really like to not need to have it switch to hibernate after 30m of sleep or w/e and ideally just plug it in overnight like a phone.

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

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. Apps that aren't pulling in random untrusted content are far less of an attack vector (eg. one's bank app isn't connecting to everything, just to the bank, pinterest is hopefully escaping user content, etc.)

Based on helpful details at the other thread (eg. Project Mainline, baseband isolation) 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 exposure. Which wouldn't necessarily mean "giving up bluetooth entirely", just not using it when you're in bluetooth range of an untrustworthy party eg. if you just use your headset to make zoom calls at home and are fine not having it on the subway.

Thanks for the reply. Definitely appreciate the point that lacklustre updates mean we need to pay attention even if we're vaguely covered by our vendor. I think you've convinced me to subscribe to CVEs for android too, I've only had alerts for my browser. Really too bad they don't make smaller Pixels.

Too many perfectly usable phones are put into a questionable security situation by lack of vendor support for keeping key software up to date.

But what's the actual risk of using an Android phone on a stock ROM without updates? What's the attack surface?

It seems like most things that'd contact potentially malicious software are web and messaging software, but that's all done by apps which continue to receive updates (at least until the android version is entirely unsupported) eg. Webview, Firefox, Signal, etc.

So are the main avenues for attack then sketchy apps and wifi points? If one is careful to use a minimal set of widely scrutinised apps and avoid connecting to wifi/bluetooth/etc. devices of questionable provenance is it really taking that much of a risk to continue using a device past EOL?

Or do browsers rely on system libraries that have plausible attack vectors? Perhaps images, video, font etc. rendering could be compromised? At this point though, that stack must be quite hardened and mature, it'd be major news for libjpg/ffmpeg to have a code-execution vulnerability? Plus it seems unlikely that they wouldn't just include this in webview/Firefox as there must surely be millions of devices in this situation so why not take the easy step of distributing a bit more in the APK?

I'm not at all an Android developer though, perhaps this is very naive and I'm missing something major?

 

I noticed that Jeroba didn't seem to switch to a different site the way Relay passed through to Reddit so I could log in and link it via OAuth. From that I take it that when I authenticate in Jeroba I'm entrusting it with the cleartext password for my lemmy account which it's storing on my phone?

I'm sorta okay with that especially for now (eg. alpha) so I proceeded with things but maybe it should be more clear up front that's what's happening? And really, any of the other apps could probably have faked that OAuth page anyhow so it's dubious if you were really trusting the app all that much less in that case.

However, one thing OAuth had going for it was that would make it a lot harder for someone who steals my phone to permanently take control of my Reddit account whereas they could extract my password from Jeroba and use it to take over my lemmy account?
