  • Conversations can be a unified push distibutor: https://unifiedpush.org/users/distributors/conversations/

    ..and I'd trust it (battery-wise) with that. I have an old tablet with conversations running without battery restrictions on it, and if I'm not actually picking it up and using it it regularly goes 1-2 weeks on an 80% battery charge before it dies, the whole time giving audible notifications for XMPP messages/calls (which I attend to on other devices).

  • To be clear though: by E2EE here I mean browser-side encryption with zero-knowledge on the server side.

    Etherpad is still encrypted in transit with https; only the server can snoop.

    Cryptpad and other web-based E2EE services can still be completely compromised server-side by serving malicious code to the browser, and practically the user would never know.

  • Cryptpad:

    • Full-on google docs / office365 / libreoffice type replacement with collaboration.
    • E2EE
    • The complexity means it doesn't work well on mobile, takes a while to load on a slow connection, more frequent bugs. (3.5 MiB page transfer)
    • Self-hosting is complicated.

    Etherpad:

    • A competent collaborative rich-text editor. Doesn't do spreadsheets or presentations or [...].
    • Not E2EE (you need to trust that the server a bit more).
    • Lightweight, works on slower connections, works alright on mobile. (1.7 MiB page transfer)
    • Self-hosting quite simple.

    PrivateBin:

    • Super-simple plain-text/markdown pastebin. No editing possible once saved.
    • E2EE
    • Very small. Works fine on slow connections and mobile. (0.2 MiB page transfer)
    • Self-hosting very simple.
  • do cars, and don’t forget to include pollution.

    ..and the health effects of lowered physical activity, social isolation, stress of long commutes in traffic, inaccessibility of vital health and social services, ...and don't forget all the externalities to supply that 2 tons of vehicle, and fuel, and roads, etc.

  • Sorry everyone, I did try searching the lemmyverse for any previous postings of this article using "signal" in the search feature on my instance, but it turned up nothing at the time.

    Lemmy.world seems to have a handle on all the cross posts: https://lemmy.world/post/9121235

  • As per the quote below, a car loses about 0.08g of tread per km.

    Compared to a car, a bike tyre is about the same diameter, 10% of the width (20mm), 28% usable tread depth ([2mm](https://sopuli.xyz/pictrs/image/118dc962-448d-41b4-b767-48d61e650b24.png)), has 50% less wheels, and can travel 10% the distance (~10000km).

    This suggests a (very approximate) tread loss of 0.08 * 10% * 28% * 50% / 10% = ~ 0.01g per km for bicycles.

    For replacing longer car journeys less typically travelled by bicycle, rail transport is the best solution and removes the issue of tyre wear.

    Quoting [deleted] in r/theydidthemath:

    Using the same assumptions as above (215/60R16 tires, 7mm of tread loss over 100,000 km), I estimate the loss of tread by volume from each tire as follows:

    Cylinder with a diameter of 664 mm and a height of 215 mm has a volume of 74,412 cm3. Cylinder with a diameter of 664-(2x7)=650 mm and a height of 215 mm has a volume of 71,307 cm3. The volume difference between a new and worn out tire is 3105 cm3.

    Typical land to sea ratio of tires is 60-70% land, depending on the type of tire. If we go with an about average value of close to 65% tread, we get the lost rubber volume of about 2000 cm3 or 2,000,000 mm3 over a single tires lifespan.

    Each revolution of a tire loses about 0,04 mm3 of tread, which, according to Wolfram Alpha, is a bit less than the volume of a medium grain of sand.

    If we look at the entire car with 4 tires over a kilometer of road, we get 80 mm3 or about 0,08 grams of tread lost per car per kilometer.
