just to be clear, the stray shock potential of a CRT had to do with the flyback circuit for tube itself, not the power supply near the power button/power conditioning.

Flybacks are deadly when live, however the tube itself was also a massive cap.

tangential: can Macsyma/Maxima do symbolic boolean algebra, reducing formulae to bog standard "OR of ANDs" form?

(I've tried looking at the doc, and it's clearly not a feature they showcase, and as others have said, the way it works is not intuitive to me. I really need this, but trying to do it in lisp is becoming its own project and I want to get back to my project. I found some really nice online reducers, but the UIs are not conducive to pasting/putting in simultaneous equations, and using those outputs as inputs again)


maxima has logic package, written in 2009 by alexey beshenov. it lives in share/logic which is also where the texi docs are. it's included with the op version,

  load(logic);
  logic_simp (a or (b or false or (a or b)));
  characteristic_vector (a xor b);
  zhegalkin_form ((a implies b) or c);
  e : ((a or b) xor c) and d$
  logic_equiv (e, zhegalkin_form (e));
  logic_diff (a or b or c, a);
  demorgan (boolean_form (a nor b nor c));
etc. there's more stuff in docs

CEOs are not a legal construct, that's the "President" of a corp, or the "Chairman of the Board". CEO is a popular sobriquet because it sounds cooler.

Incorporations are legal constructs. Any position in one is even more so.

Corporations are required by law to have Presidents and Chairmen. That is the legal construct.

They are not required to have CEOs who therefore sit on shakier legal ground.


> Corporations are required by law to have Presidents and Chairmen

Varies by jurisdiction. Common ones are a president, secretary and treasurer. (They can be the same person.)


there is also competition for limited/expensive shelf space in the supermarket and only-so-much advertising media that must be shared with all other products

I'm old enough to remember that there used to be choices for different brands of various types of flakes: people use their dollars to exercise choices in the space of products to choose from, and they aren't any longer looking for a "dirt cheap corn flake shootout"

yes, there are also nonlinearities like minimum viable factory size, which leads to market concentration heading toward monopolization, but those factors are not specific to corn flakes nor driving that market.

did you know that Frosted Flakes are actually just stale corn flakes that are revived by spraying them with sugar? I used to work for a company modelling factory automation, and that was part of the model. So, if you don't sell sugar cereals, you're not as efficient.


you say generous... I think it's great that he's offering the arbitrage, but through his ebay account implies there will be a charge, no? could still be a very reasonable price but...

what this comment section is missing is "hey, here are other pages that do the same thing is a slighty different way" (there must be tons!? I would enjoy and learn from those type of comments so much I that I'd shout, "this is a motherfucking comment section!" https://motherfuckingwebsite.com/

unlike the <blink> tag where younger people will just stare at you in a creepy extended unblinking gaze. it would be so much more satisfying if it still made them blink.

I absolutely need to write a polyfill for that.

   blink {
     animation: 1s ease infinite blink_effect;
   }

   @keyframes blink_effect {
     0% {
       opacity: 0;
     }
     50% {
       opacity: 1;
     }
     100% {
       opacity: 0;
     }
   }

for certain elements, a quinesque approach might not be that useful, but source could be displayed juxtaposed to results. (to show numbered lists, do you want to display the ol tags before the numbers (thus using fake numbers) or do you let ol numbering tags tag the elements with numbers and then show the source inside that?)

btw it really drives me crazy that browser implementors think that when I copy/paste a numbered list, I somehow don't want the numbers.


(your comment is very minimally informative, containing 1 bit of information: "there is something to learn about ruby". Searching "show source", "hidden gems" on OP's page marks the ruby spot)

and looking up the <ruby> tag:

https://interactive-examples.mdn.mozilla.net/pages/tabbed/ru...

The <ruby> HTML element represents small annotations that are rendered above, below, or next to base text, usually used for showing the pronunciation of East Asian characters. It can also be used for annotating other kinds of text, but this usage is less common.

The term ruby originated as a unit of measurement used by typesetters, representing the smallest size that text can be printed on newsprint while remaining legible.


I think it's very clear what he meant

Oh wow, TIL the HTML element for furigana is <ruby>

>30 years ago in London, you'd of said the same thing about places like Hackney...[and] today it houses some of the most desired and valuable real estate

are you saying that gentrification of Hackney did not simply entail wealthier people moving in and displacing the local population, but rather soaring incomes for the people who lived there?


A "gentrified" community will involve higher incomes for those non-tradable services that have to be provided locally and can't simply be outsourced to somewhere else. So it's both.

(This is in addition to the high productivity that's driving the gentrification in the first place, which will often result in increased opportunity in that very sector - but that's not always very relevant, especially in the short term.)


Emphasis on 'to a certain extent' :)

Educational outcomes need to be improved yesterday, no disagreement on that.

There's some displacement, yes. However anyone who isn't in privately rented accommodation would be choosing to leave, perhaps even with some decent money from selling their house.

Many people stay, if you'd like proof, take a walk down to hackney.


I find this a strange reasoning. When a city becomes more economically viable everyone benefits.

The poor people in Amsterdam get benefits paid for by the rich.
