I've described this on HN before; forgive me if you've already seen it. I have chronic migraine. It sounds worse than it is; I rarely suffer attacks anymore, and when I do, they're usually mostly harmless, as in the case I'll describe below. Contrary to popular belief, migraine is not a headache. It's something a little more like an epileptic seizure. Intense headaches are one common symptom, but there are a lot of o…
Interesting. I get these scotomas about every 6 months or so, usually lasting for 30 or so minutes. I was told they were called "ocular migraines", and a cursory glance over the internet doesn't seem to help me differentiate between the two, although I will say that [0] is a very accurate depiction of how it looks when it happens to me. I normally just take a break from whatever I'm doing and go for a walk. The first…

#332Humans might just be the stupidest animals on the planet when it comes to seasonal migration, we get tied down by our monetary system, taxes, government policies, borders, etc., while polluting our planet with patchwork solutions like air conditioning for the summer or burning fossil fuels to heat our surroundings in the winter. We can't simply just "move" to a different location like other animals.

I think it's the opposite. We can move, but we have the intelligence to tame our environment so we don't have to.

#334Double-clicking on text selects the whole word. Double-clicking and dragging selects text word-by-word. Triple-clicking selects the whole paragraph. Middle-clicking a link opens it in a new tab. Middle-clicking a tab closes it. Middle-clicking in general often has useful functionality!
In code-editors tripple selects a line (hold to select multiple). When moving/deleting lines this is much more semantically clean (and faster) than manually dragging from the previous line's line end to the next lines last character before the line end.

#335Earlier quoted context omitted.
I have experienced this several times and almost never have a headache. I definitely can't read what's beyond/obscured by the scotoma. The first time it happened was during a test in high school and the splotch grew until I was forced to read the questions in my peripheral. I have an anecdote that corroborates your observation that cognitive experiences are more complicated then assumed: I was once very, very sleep d…
One of the other weird things I referred to is best described as discovering that I could be awake and asleep at the same time. I think it might be another case of our naive ideas about cognitive processes being a little oversimplified. It sounds like nonsense, of course, but that's because we naively assume that sleep and wakefulness are opposites--that they are mutually exclusive. What if we're wrong about that? Wh…

#336What we call “free will” consists of a multitude of forces we have no control over. Look at your choices and try to find an independent entity making a decision. You will likely notice your conditioning and preferences, beliefs, emotions, thoughts, physiological and psychological state in the moment, your environment, habits, trauma patterns, all collaborating toward one thing or another. “Free will” is a shortcut fo…

#337In the 1800s, scholars who knew a lot of languages (including, often, several modern and ancient European languages, and increasingly also Sanskrit) started to notice some amazing patterns about similarities in words among all of these languages, including languages from very far apart and that had no visible connection at all from the point of view of their present-day speakers. As these patterns were explored, they…

Taming the environment is proving to be bad, isn't it?

#339Back in the 00's an Irish heritage group in Canada bought a chunk of land in Ontario and managed to get it designated as a Gaeltacht.
So officially, as of today, Irish is the common vernacular in several small-ish regions of Ireland and a .25km^2 chunk of Canada.
