Seems pretty obvious those are the facts; and I don't really see any mitigating circumstances. I have no objection to defederating.

@arteteco @Sphinx

@freemo thanks! What's the context here? In particular, was this experiment conducted under sunny conditions?

@freemo the sun may be a small portion of the sky, but the temperature difference between the sun and your body is thousands of kelvin, whereas the difference between your body and your other surroundings is tens of kelvin. Since radiative transfer scales with the fourth power of temperature, I don't think you can neglect that mechanism (and the ballpark numbers I ran above suggest that it actually dominates over the IR transfer). On top of that, the snowy surroundings are going to be reflecting sunlight at you from a much greater area.

@freemo why does that dominate over the benefits of absorbing maximal energy from solar radiation? It looks like it's about an order of magnitude more energy in this mechanism

@freemo So ideally you'd want something "black" to visible light and "white" at infrared wavelengths to both absorb external radiation and reflect internal black body radiation inwards. Assuming you can only have one or the other, a quick back of the envelope calculation suggests that the sun's radiation, which is on the order of a kilowatt per square metre and would be irradiating roughly your frontal area (let's call it one square metre, total 1kW) at polar midsummer, is the dominant effect over your body heat, which I estimate as 2000 kcal/day, roughly 100W. So I'll go with black.

@freemo

White clothes are better camouflage in a snowy environment. Getting killed by a polar bear would cause your body temperature to drop to ambient; thus white clothes are an advantage for staying warm.

@valleyforge

@valleyforge I remember trying to figure out what that project was a while ago - I eventually concluded that it is the zombocom of software

@freemo is this the same principle as groundwave/skywave differences that make AM radio much better at night?

@rchrd

@namark enough bells & whistles to make it worth it. Little file browser follows you around, resizable tabular view of variable matrices like spreadsheets, command history log, it adds up to a rather nice experience. The built in IDE can go choke on a porcupine though - its auto indentation in particular really fights me every step of the way.

@aluaces It appears to affect more than one desktop environment (but only Octave, not other programs on the machine). I'm experiencing it on Cinnamon, and [here](https://reddit.com/r/pop_os/comments/hg2xjm)'s a guy with the same kind of problem on something called Pop Shell.

Does anyone use GNU #Octave #GNUOctave on Linux? Every time I switch workspaces it keeps hoisting itself on top of the other programs I have running - I would love to learn how to disable this behaviour.

@shoshin I'm not sure what you gain from airing this publicly - if you violate the rules you won't be welcome on this server. I did you a courtesy by only removing the post and warning you since racism is technically a banning offence. Racist jokes don't get a free pass because they're humour; they are subject to the usual rules about racism which you can find at qoto.org/about/more.

@louisrcouture thanks for these posts! I really appreciate the very literal translations because I frequently learn a new word or two after puzzling over the French and then seeing the English later.

@worldsendless [Feeder](https://gitlab.com/spacecowboy/Feeder) is nice. I like that I can set specific feeds to trigger notifications while others just silently add their contents to the overview.

From its readme:

> Feeder is a fully free/libre feed reader. It supports all common feed formats, including JSONFeed. It doesn't track you. It doesn't require any setup. It doesn't even need you to create an account! Just setup your feeds, or import them from your old reader via OPML, then get on with syncing and reading.

Anyone with a #stats #statistics background:

I have a record of several hundred events. Each event occurred at a particular univariate condition x and had a binary outcome y. I don't get to choose x; there are about a hundred values that occurred exactly once, up to a maximum number of fourteen repetitions at one value of x (to measurement precision). The samples are roughly clustered around a central value of x, not uniformly distributed.

Is there a recommended way to estimate the local probability of y as a function of x (that is, if I measure the conditions as x=X, how likely is it that y will occur)? Simply averaging all samples at x=X doesn't give a usable curve, because all the single-sample values swing it wildly to zero or one, regardless of what any neighbouring samples have done. Currently what I'm doing is summing the averages over all samples where x<=X and the average over all samples where x>=X, then subtracting the average over all x. It looks more or less like the smooth curve predicted by theory but I'm pretty sure this counts as "misuse of statistics".

I'm especially interested in identifying regions (intervals on x) where I can say the observed probability differs from the prediction of theory by a statistically significant amount. I think coming up with a formula for a confidence interval would be the way to go, but feel free to point me in another direction.

@valleyforge Well, for certain values of "you":

> City, county, state and federal agencies, public schools, public and private institutions of higher education, public hospitals and political subdivisions are eligible to buy from TCI.

> Ineligible entities include, but are not limited to, non-profit corporations, private schools, private hospitals, private enterprise and individuals.

@valleyforge I'd say right-wing and left-wing groups are both deontological, but with different orders of preference in their rulesets. The political centre is where you find people who value pragmatism over principle.

@realcaseyrollins couple Canadian ones I know of relating to Sikh religious objections to dress codes:
Sikhs may not trim their hair, including facial hair, in respect for the natural state of their body as intended by God. In the military, they can legally be ordered to modify their hair for operational need (e.g. to accommodate gas or oxygen masks), but in the absence of such orders, are exempt from the normal regulations concerning hairstyles.
Sikhs must carry a dagger, to maintain readiness to defend the helpless. Schools cannot prohibit the wearing of the dagger, but can require it to be immobilised in its sheath so it cannot be drawn.

@louisrcouture Crazy Richard's

@Acer "cardinal direction" for north + east + south + west. Maybe "handedness" for the other pair, but that implies only a subset of the possible meanings of the original terms.
