Today I Learned

In summary: Today I learned that Lagrange was Italian and that he lamented the execution of Lavoisier in France during the French Revolution with the quote:"It took them only an instant to cut off this head and a hundred years might not suffice to reproduce it's...brains."

I learned that if one particle of dust is introduced onto a silicon wafer, during production process, the whole batch can be at risk of being ruined. Creating a microchip from silicon is a very, very meticulous process demanding extreme precision and care.

It takes an average of 12 weeks to make one of these chips. Who knew. . .

And then you learned about the fascinating story of how this guy did one at home, something experts thought was impossible:

Yeah, but way different feature sizes.

It's no fun getting into a bunny suit to go into a fab to debug machine problems (especially if you have to bring your instruments with you)...

Amazon is gutting its voice-assistant Alexa. Employees describe a division in crisis and huge losses on 'a wasted opportunity.'​

https://www.businessinsider.com/amazon-alexa-job-layoffs-rise-and-fall-2022-11

So, no futuristic A.I. voice/bot assistant in every U.S. home on the horizon? And I thought we were getting closer and closer to Star Trek living.

I also didn't know Alexa was behind Google Assistant and Apple Siri in use/popularity.

I tried. I was told the site was unsafe, then the whole thing went into an infinite loop.

I was not referring to the PF Singularity though, I was referring to the hidden USER menu in the mobile interface. There is no indication it is there until you happen to click it.

Edit: Actually, it is not just the mobile interface. Shrinking your browser width enough leads to the same effect.

Oh! We had this discussion recently and I commented: "I want to speak to the programmer!" so I missed the point.

Oh yes, there is an icon missing! @Greg Bernhardt was this not resolved recently?

I mean, not only is there a missing icon. It is displaced vertically and smaller than the other menu icons.

Yeah, it's missing on my phone. But this is what it looks like on PC:

I'm not too surprised. I've thought about working on a similar program for a WW II game called Squad Leader starting with just a few types of units and minimal rules. That will have to wait until I retire. :oldwink:

I believe this was slang mostly used by Canadians during WW2. I recall it from some of my books.

It was WWII era British army slang, I gather, although I don't know how widespread or long lasting.

Yeah. My dad didn't like the phrase because he associated it with someone making fairly serious efforts to kill him. Like I say, I don't know how widespread the usage was.

WW2?

Yes after a search there are a lot of applications. Marbles (origin claimed there on one site) being drunk (Oz) stock market, Artillery fire and
Not a word you hear often in the UK, not North West anyway.

I had no idea of any of those other connections.
Including the stock market or darker military ones.

I put stonking with 'spiffing.' An Etonian, Wodehouse type of phrase.
"Everyone had an absolutely spiffing time."

Yes - he'd've been 100 next year.

I agree it's not a common phrase these days in any context. I only learned of the artillery fire connotations because Comic Relief did a novelty single called "The Stonk" one year and my dad grumbled about it not sounding comical to him.

I have such a feeling that it somehow should have changed, if outspoken, and did already, in reality, change to: Don't mention the Brexit!

Brexit is like the interpretations of Quantum Mechanics discussions. I read the threads that seem to follow the same lines but I come away from them with little recall or understanding of them.
