I'd actually assume closer to 100km of coverage, 60 miles or so is a conservative estimate of coverage, in the prairies I would expect it to go much further - 500w of output on high band VHF goes quite quite far - I know how far the US NWS stations cover, and its much closer to 60+ miles.

Environment Canada assumes 60 km on their Weatheradio page ( https://www.canada.ca/en/environment-climate-change/services... ), so that's what I went with. Having said that, I very much agree that the range is probably considerably greater in many cases.

Here's a map I put together of the Weatheradio (one "r"!) service coverage in Canada, assuming each station has a range of 60 km: https://www.keacher.com/files/dir12/weatheradio_map2.png Perhaps unsurprisingly, the coverage is most dense where the population density is also highest, with some exceptions.

And if anybody is curious, here's the coverage for the equivalent Weather Radio service in the United States: https://www.weather.gov/nwr/maps

I'd maybe make a hypothesis that a large portion of the space is "bad" smelling stuff: smoke or garbage. When people had covid-induced parosmia, it almost always seemed to be bad smelling stuff.

That was exactly my thought when reading the article and my personal experience with Covid. For a couple weeks, I perceived a persistent smell of something burning.

The problem with data center water usage is that it is unnecessary from the PR point of view. Data centers can run on air cooling just as good, but more expensive. For all I know, we could also do just as good without data centers, like we did 20 years ago.

With agriculture, water usage is necessary as eating is not something optional and everyone needs to eat to survive. From the PR point of view, of course. We couldn't live without agriculture, as we had agriculture 20 years ago too.

Golf courses are unrelated as they don't use nearly as much water as agriculture or data centers.

PR is everything, the narrative is what makes the difference. There is a lot of hypocrisy in this field, which is why I try to avoid it, but there is also some truth in it - we really didn't need that many data centers 20 years ago.

Golf courses in the USA used about 2.1 billion gallons of water per day circa 2004 [1]. In other words, the annual usage of Amazon's datacenters per the article, 7.7 billion gallons, is less than the amount of water used on just American golf courses in four days.

> All natural uranium today contains 0.720% of U-235. If you were to extract it from the Earth’s crust, or from rocks from the moon or in meteorites, that’s what you would find. But that bit of rock from Oklo contained only 0.717%.

Heh. The garbage web software developer me would have just called it good enough

Would be really interesting to know what the error bars on those figures look like

Per NIST[1], the value is 0.7204% +/- 0.0006%, with the uncertainty representing one standard deviation.

I don’t understand why PSA levels aren’t included as part of the standard blood work done with check ups.

teuobk · 10 months ago

Current evidence is that PSA tests don't actually save lives:

I wish they did, of course. I personally lost a close friend to prostate cancer last year. He was 41 and was, before the cancer, one of the healthiest and most athletic people I knew.

The first inkling he had that anything was wrong was a backache that wouldn't go away; a stage 4 diagnosis ensued. He held on for 21 months from the onset of symptoms before the cancer took him.

"Epochalypse" is a nice coinage. Not a new one either, this 2017 article attributes it to Mikko Hypponen (of F-Secure). https://www.tomsguide.com/us/2038-bug-bh2017,news-25551.html

teuobk · 10 months ago

Goes back at least slightly before that, as I've had 2038epochalypse.com registered since March 2017, but I can't recall whether I thought I was being clever or whether I heard it somewhere else.
