As was mentioned in another comment, it’s a statistical term that measures the standard deviation. It basically tells you how “far” from the center of the bell curve you are with your data points. The higher the sigma, the less likely it is that an observed event was a fluke.
For example, 1-sigma event has a 37% chance of being a “coincidence”, and 2-sigma has a chance of about 4.5%.
In science, 3-sigma (0.135%) is the first publishable certainty, it’s when something becomes significant enough to start a discussion.
And 5-sigma is the most common threshold for claiming discovery. 5-sigma events have a 0.0000287% chance of being a coincidence or some random happenstance. Or one in 3.5 million.
Higgs boson discovery was announced after 5-sigma certainty was reached. It means that if that particle didn’t actually exist, the chance of the experiments producing observed results would be 1 in 3.5 mln.
I read the article and I still don’t really understand how exactly it’s supposed to work. I guess it can detect some deformation within the cable, but is this deformation guaranteed when a leak has occurred?
Does it give false positives or false negatives, and how often? Would different placement along the pipe matter? And is there some measurement besides “the cable has slightly deformed somewhere”? Like, is there a way to find the location of the leak, for example, or should the pipe be checked along the whole length of the cable between detectors?
Non-Fungible Tokens, or NFTs for short are shaking up the virtual universe, transforming how we vibe with digital assets.
Oh hello fellow humans. Let’s vibe with our digital assets for a bit since it’s something we do so often in our virtual universe. What assets do you especially enjoy vibing with?
Trademark research would require paying people. Can you imagine that? Shudders.
At least you can always find designers who are happy to work for free. Sure, it might be just a Unicode character, but it has animated glitches tho. Those are cool.
Articles like these lower future Reddit’s valuations. It lost like 60% of its original price, and I’d guess it wasn’t primarily because users protested, but rather thanks to many reputable tech news outlets covering the shit storm.
Would a temporary uptick in users be worth it in the long run? I kinda doubt it.
I recently read a pretty interesting take that a lot of this started because Silicon Valley Bank failed, and now all these companies have to do something they haven’t really had a necessity to do before — to make profit.
And all of them aren’t run by business geniuses as previously believed, on the contrary, most of the leaders are so disconnected from reality that they genuinely have no idea what people want in a service, they can’t take feedback or advice because “they know better”, and all the other stuff that comes with that.
So they do what they think is right, while missing the whole point of the product they are so desperately trying to make profitable.
Look at spez’s “we’ll stay profit-focused until profits arrive” and Musk’s rush to get at least some ROI on his $44 bn middle age crisis toy.
I remember Sam Altman’s interview where he was going about how the funds from AI breakthroughs should fund UBI programs and be used towards the betterment of mankind in general.
They do, and here I was going to add “but they’re a bit less fun”, but after reading the wiki article I’m not sure.
Due to their effects and symptoms, Datura species have occasionally been used not only as poisons, but also as hallucinogens by various groups throughout history. Traditionally, their psychoactive administration has often been associated with witchcraft and sorcery or similar practices in many cultures, including the Western world. Certain common Datura species have also been used ritualistically as entheogens by some Native American groups.
When I was a kid, I spent a few summers living nearby a sunflower field. At the end of the season, snatching a flower with some friends and munching on those seeds was the best thing ever :)
We would often roast them over a bonfire holding the flower by its stem.
A while later, someone gifted that book to me. I barely started it and put it away, and it was lying around the appartement for 2 years. One day I randomly picked it up and finished it that day. Went from 20 cigarettes a day to 0 overnight. That was like 13 years ago, and I never wanted a cigarette since.
That 90% success rate seems to be the case within my friend group as well :)
Interesting, haven’t heard about that. Can you give an example of how it’s used in business? What is actually measured?
