Oh nice - I'm literally playing around with a site to detect outages for major provides (AWS/cloudflare/github) based on social media/HN posts

It is the first technology that is truly useful for handling unstructured data.

Processes that rely on unstructured data are usually unstructured processes.

I appreciate someone succinctly summing up this idea.

This is a nice summary. I do devops/infrastructure for a SaaS company that use DDD and this was helpful for me to refresh my knowledge of terms and concepts

I wonder if this could be helpful for those who are sight-impaired.

Sometimes consumer devices don't have widespread appeal but are so useful for some groups

For example, my grandfather when basically completely blind in his 60s. When Alexa came out in his 90s it made such a different to his quality of life in his final few years.

She might find a device like Alexa helpful if reading no longer becomes an option - with it she can get audio books, music etc.

My grandfather was a avid reader (mostly history ww2 and ww1) and went blind in his 70s. We got him a Alexa and he found it fantastic. It was a major improvement to his quality of life in his final days.

As European, it's insane to me that American get so little time off. In my country we get 4 weeks leave mandated by law plus public holidays.

Wow!

Telegraphs

Because of the geomagnetically induced current from the electromagnetic field, telegraph systems all over Europe and North America failed, in some cases giving their operators electric shocks.[22] Telegraph pylons threw sparks.[23] Some operators were able to continue to send and receive messages despite having disconnected their power supplies.[24][25] The following conversation occurred between two operators of the American telegraph line between Boston, Massachusetts, and Portland, Maine, on the night of 2 September 1859 and reported in the Boston Evening Traveler:

    Boston operator (to Portland operator): "Please cut off your battery [power source] entirely for fifteen minutes."

    Portland operator: "Will do so. It is now disconnected."

    Boston: "Mine is disconnected, and we are working with the auroral current. How do you receive my writing?"

    Portland: "Better than with our batteries on. – Current comes and goes gradually."

    Boston: "My current is very strong at times, and we can work better without the batteries, as the aurora seems to neutralize and augment our batteries alternately, making current too strong at times for our relay magnets. Suppose we work without batteries while we are affected by this trouble."

    Portland: "Very well. Shall I go ahead with business?"

    Boston: "Yes. Go ahead."
The conversation was carried on for around two hours using no battery power at all and working solely with the current induced by the aurora, the first time on record that more than a word or two was transmitted in such manner.[26]
