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.

Do you know about the one for healthcare on the 25th?

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

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?

Allied Properties sale of their data centre portfolio to KDDI includes 151 Front Street W., the site of TorIX which is the main Internet Exchange Point for the country. 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.

Unfortunately, it seems like it's less consequential than it should be because Bell Canada apparently still refuses to peer at TorIX and only connects to other ISPs through the US which means that eg. if I'm on Rogers in Toronto and you're on Bell, any communications between our computers have to flow through American controlled systems even though we're in the same city because that's how Bell chooses to have things set up.

Whereas, for pretty much everything else in Toronto, it'd move between networks via TorIX. Which is now in a building owned by a Japanese company instead of a Canadian REIT.

Good. This law is ridiculous and I'm glad it won't give the result they intended. Being able to link to things freely is a very basic part of the web, we really shouldn't mess with that. And Facebook is a ridiculous place to get news from so it may have ancillary benefits as well in terms of maybe slightly improving public discourse and encouraging people onto other platforms with more transparency around their content weighting and data use practices.

https://simple.wikipedia.org/ is a good alternative sometimes and I'm glad it exists, but that's almost the opposite problem.

It does seem like they make an effort, their style guide starts out with "Probably the hardest part of writing a Wikipedia article on a mathematical topic, and generally any Wikipedia article, is addressing a reader's level of knowledge." https://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style/Mathematics
