you probably didn't define the function, f(x,y), which is the line before plot3d. it's a slightly buggy behavior

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

because nobody knows maxima, some things to try. also plot2d/plot3d work, so that's pretty neat. the whole thing is powered by https://ecl.common-lisp.dev and the op announcement is here https://mailman3.common-lisp.net/hyperkitty/list/ecl-devel@c...

  :lisp (+ 2 2)
  solve(f(x)^2-1,x);
  integrate(x^2,x);
  2^1024;
  factor(30!);
  a:1
  b:2
  a+b;
  sqrt(a^2+b^2);
  expr: log((x+2)*(x-2))+log(x);
  ratsimp(expr);
  fullratsimp(expr);
  trigsimp(2*cos(x)^2 + sin(x)^2);
  solve(x^3=1,x);
  diff(sin(x), x);
  float([%e,%pi,%phi,%gamma]);
  f(x):=x^2;
  f(10);
  taylor(sin(x),x,0,5);
  plot2d(x^2-x+3,[x,-10,10]);
  plot2d([x^2, x^3, x^4 -x +1] ,[x,-10,10]);
  f(x,y):= sin(x) + cos(y);
  plot3d(f(x,y), [x,-5,5], [y,-5,5]);

i've been publishing things as html2 pages, but not interconnected in any way. so each page (or sometimes group of pages) will be dedicated to an exploration of a single subject. i then send those pages to people who i think might be interested in them. that's all, they otherwise don't see the greater internet. of course people are free to add them to link aggregators, etc. but i don't police this practice. i simply don't care for my output to be consumed by general public, or by llms, or by corporate media, or by whomever who is not my friend or in my immediate immediate circle of friends

i'm responding to op's callous and partisan take.

also the comment originally read "What does it have to do with the crash", which was immediately edited to "How do you know Biden forcing them back to work has anything to do with the crash?"

i will respond to the last one i saw: i don't. i'm pointing out that the wikipedia article about the 2022 union strike makes an argument that the strike was explicitly about safety. here's a vice article that goes into awful and terrifying details <https://www.vice.com/en/article/pkp9m8/what-choice-do-i-have...>. biden's forced solution did not address the original safety concerns beyond "1 day of sick leave".

(edit: 2 minutes after posting this i got downvoted. the level of political discourse…)

<https://en.wikipedia.org/wiki/2022_United_States_railroad_la...>

"The rise of precision scheduled railroading has resulted in resource and staffing cuts; to compensate railroad companies have enacted strict attendance policies for employees. These policies eliminate any free time which workers have, requiring them to be effectively on-call for weeks at a time. Workers have complained of increased levels of stress and fatigue."

"Unions representing about 17,000 workers threatened to strike over the points system, but BNSF Railway sued and won a restraining order to prevent the unions from striking. The Railway Labor Act grants Congress the authority to intervene in any railway or airline strike. Under this authority, the National Mediation Board has mediated negotiations between multiple freight railroads and unions starting in June 2021."

"Early on September 15, Biden announced a deal had been reached to prevent a strike, including an immediate 14% wage increase, but only one day of paid leave per year rather than the 15 days of paid sick leave unions wanted." "In late November, after some unions had rejected the agreement, Biden asked Congress to pass the agreement into law."

"Writing for Jacobin, Barry Eidlin, associate professor of sociology at McGill University, said the message sent to the rail workers by the president and Congress was "shut up and get back to work." The Biden administration's intervention in the dispute was condemned by over 500 labor historians in an open letter to Joe Biden and Secretary of Labor Marty Walsh."

you're right, the other comment led me astray and i didn't check. it's just partisan trash. so to make up for it,

Wp starts its `background` analysis <https://en.m.wikipedia.org/wiki/2022_United_States_railroad_...> with `The rise of precision scheduled railroading has resulted in resource and staffing cuts; to compensate railroad companies have enacted strict attendance policies for employees. These policies eliminate any free time which workers have, requiring them to be effectively on-call for weeks at a time. Workers have complained of increased levels of stress and fatigue.` The bulk of the argument is supported by this vice article <https://www.vice.com/en/article/pkp9m8/what-choice-do-i-have...> which is frankly horrifying. It's a bunch of quotes from train conductors talking about falling asleep, being tired, taking caffeine pills, etc. It ends with a 2020 derailment. "A BNSF TRAIN CARRYING OIL TANKERS DERAILED IN WASHINGTON STATE IN 2020. WORKERS ARE WORRIED MORE CRASHES LIKE THIS WILL OCCUR UNDER THE NEW ATTENDANCE POLICY."

Wp again "Unions representing about 17,000 workers threatened to strike over the points system, but BNSF Railway sued and won a restraining order to prevent the unions from striking. The Railway Labor Act grants Congress the authority to intervene in any railway or airline strike. Under this authority, the National Mediation Board has mediated negotiations between multiple freight railroads and unions starting in June 2021." and there's your crux.

then a bunch of back and forth happens, and then it ends with biden/congress/senate doing their thing. it seems like the gist of the forced solution was to raise salaries and some sick leave, but no other mitigations.

wp again, "Writing for Jacobin, Barry Eidlin, associate professor of sociology at McGill University, said the message sent to the rail workers by the president and Congress was "shut up and get back to work." The Biden administration's intervention in the dispute was condemned by over 500 labor historians in an open letter to Joe Biden and Secretary of Labor Marty Walsh."

it would make sense for you, a midwest defector, to be willing to make concessions for your birthplace, but i don't think you speak for the coastal america. on the other hand the minstrel show midwesterns that you selected to represent the entire region wouldn't have any connection to the west coast, if not feel outright hostility. the hostility might have more to do with cultural and political divide that you yourself is expressing, than it does with the midwestern capacity for compassion. i am a total outsider to the region, but i've seen about as many church mission trips to help the needy as i've met ngo activists in cities, which necessarily makes for a much larger proportion of people.

i personally want whoopi goldberg to go over the shipping manifest <https://epaosc.org/sites/15933/files/TRAIN%2032N%20-%20EAST%...> during her day time show, and eli5 to her listeners what those various substances are, what their short and long term effect on the environment are, and specifically the effects on the various ohio river tributaries where EPA has already detected some of the contaminants. i know that's too much to ask, so a passing mention would be good enough. i /suspect/ people who think it should be covered more find the situation to be horrendous enough to warrant that kind of media reaction.

from another thread, https://time.com/6238361/joe-biden-rail-strike-illegal/

his fvwm config is public, and there's a screenshot floating around, if you want to take a closer look https://www-cs-faculty.stanford.edu/~knuth/screen.jpeg

the only mistake you won't be able to correct from observing screenshot is the "look like org-mode" thing. it's https://www-cs-faculty.stanford.edu/~knuth/programs/color-mo... minor mode which lets you highlight arbitrary lines in a buffer.
