    1. The default fill_in method of Capybara is case sensitive. This is apparently due to their use of XPath. Anyhow, this seems to not be very well aligned with the entire idea of DSLs and letting non programmers write tests.

      not very well aligned

    1. Manmade CO2 Does Not Cause Measurable Warming

      Actually, CO2 does cause measurable warming. The warming effect is not huge, and not worrisome, but it is not zero, and it is large enough to be measurable.

      There really is no question about the fact that the Earth's average temperature has warmed slightly, as CO2 levels have risen, over the last six decades. The magnitude of that change is debatable: different "global" composite temperature indices vary in their measured trend by approximately a factor of two. But none of them show zero trend.

      The "climate sensitivity" of the Earth's temperatures to changes in CO2 level can be estimated by careful comparison of measured temperatures to measured CO2 levels. Here's an example on my web site, showing how that can be done:

      Climate change is a highly politicized issue, so, as is the case for any politicized issue, if you want to understand it you need to seek out balanced information. If you want to learn about the SCIENCE of climate change, instead of political spin, here's a list of resources which can help:

      It has:

      ● accurate introductory climatology information

      ● in-depth science from BOTH skeptics & alarmists

      ● links to balanced debates between experts on BOTH sides

      ● information about climate impacts

      ● links to the best blogs on BOTH sides of the issue

    1. Carl T. Bergstrom. (2021, January 31). A somewhat technical thread about measuring vaccine efficacy. We’re used to the notion that certain properties of tests for disease depend on prevalence: Positive and negative predictive value do, for example, whereas sensitivity and specificity do not.

    1. The trigger warning signals not only the growing precautionary approach to words and ideas in the university, but a wider cultural hypersensitivity to harm and a paranoia about giving offense.

    1. the ancients were sensitive primarily to such things as luminosity, saturation and texture, or even less obvious variables such as smell, agitation and liquidity.

      So this is helping me think of sensitivity as the condition of possibility for "sensibility" or sense-ability. Before a thing is available to be sensed, the sensitivity has to be open/operating.
