  • I think this project has some tools that might automate that:

    https://0xacab.org/dCF/deCloudflare

    They ID and track every website that joins #Cloudflare. It’s a huge effort but those guys are on top of it. A script could check the list of domains against their list. There is also this service (from the same devs) which does some checks:

    https://karma.crimeflare.eu.org:1984/api/is/cloudflare/html/

    but caveat: if a non-CF domain (e.g. example.tld) has a CF host (e.g. somehost.example.tld), that tool will return YES for the whole domain.

    Manually adjusting availability is a can of worms that I don’t want to open

    I would suggest not bothering with any complex math, and simply do the calculation as you normally do but then if a site is Cloudflare cap whatever the calculated figure is to 98%. Probably most (if not all) CF sites would be 100% anyway, so they would just be reduced by 2%. Though it would need to be explained somewhere – the beauty of which would be to help inform people that the CF walled garden is excluding people. Cloudflare’s harm perpetuates to a large extent because people are unaware that it’s an exclusive walled garden that marginalizes people.


  • Cloudflared services like ani.social are getting a “100%” available stat. That site may be up but it’s unavailable (denying availability) to something like ~1-3% of the population 100% of the time. So in principle it should never be able to achieve the 100% availability stat.

    I understand it would be quite difficult to calculate an availability figure that accounts for access restrictions to marginalized groups, because apart from Cloudflare you would not have a practical way of knowing how firewalls are configured. But one thing you could (and should) do is mark the known walled gardens in some way. E.g. put a “🌩” next to Cloudflare sites and warn people that they are not open access sites.

    The lestat.org availability listing is like a competition that actually gives a perception advantage to services that exclude people, thus rewarding them for compromising availability. I would also subtract off ~2% for all CF sites as a general rule simply because you know it’s not 100% available to everyone. They do not deserve that 100% trophy, nor is it accurate.





  • A radiant floor is just a heat transfer system that still needs a hot/cold source. Evaporative coolers (aka swamp coolers) are really the modern day equivalent.

    @oshaboy@lemmy.world

    Maybe as a supplement to Air Conditioners.

    Swamp coolers only work when the outdoor air is quite dry (Arizona, Nevada, New Mexico). The resulting indoor air is very humid. Swamp coolers cannot make a big difference in temp. In NM they are perfect because the air is dry (too dry for comfort, IMO) and you only need to lower the temp by a small amount. So the resulting indoor air quality in NM is perhaps the best in the world for those who like ~65—70% humidity. A lot of swamp coolers in AZ have been replaced with A/C because the city temps have increased¹ to a point where swamp coolers cannot make a sufficient temp decrease. So I wonder if an AZ residents kept their swamp coolers going & added A/C. Note that A/C dries the interior air, so I suspect the swamp cooler might actually be make the A/C work harder in that scenario. If anyone knows something concrete about this I’d be interested in hearing it.

    ① One theory on the temp increase in AZ cities is simply more and more concrete covering the ground (roads, parking lots, driveways), less soil and vegetation. This means rainwater is drained off instead of having the large scale evaporative cooling effect of soil & vegetation absorbing water temporarily until it evaporates. IMO one correction (apart from reverting parking lots to gardens) is to get roofers installing vegetated rooftops. I really don’t understand why #vegetatedRooftops are nearly non-existent in the US. Pick any city and call every single roofing company in the region, and most likely not a single one of them can do #vegetatedRoofs.
