Paradox on 72nd Street

[edit]

How can I watch the PBS documentary Paradox on 72nd Street (1982)?[1][2] Oddly, the film has disappeared from the face of the Earth, and even stranger, in the linked reviews, the NYT calls it "fascinating" and "persuasive" while the WaPo pans it as unwatchable. That's about as extreme of a difference in opinion that you can get. But, I want to see it for myself. Viriditas (talk) 03:12, 24 October 2025 (UTC)[reply]

Use of book jackets

[edit]

Do organizations like OCLC and libraries and book sellers claim fair use when scanning covers? DMc75771 (talk) 22:51, 24 October 2025 (UTC)[reply]

Are you sure OCLC has anything to do with it? It looks like they are pulling data from Google Books or Goodreads. Viriditas (talk) 22:56, 24 October 2025 (UTC)[reply]
Looks like I was wrong.[3] Viriditas (talk) 23:00, 24 October 2025 (UTC)[reply]
Or maybe I was right all along.[4] Viriditas (talk) 23:02, 24 October 2025 (UTC)[reply]
I don't know where the covers are from. DMc75771 (talk) 23:59, 24 October 2025 (UTC)[reply]
It says in the last link I gave you ("Examples of OCLC partnerships"). The cover art is from the publishers. The OCLC (and libraries) are using licensed images. Viriditas (talk) 00:17, 25 October 2025 (UTC)[reply]
I suspect they don't really need to claim fair use, because book covers are implicitly advertisements for the book, so these organisations are in effect performing free advertising for the publisher, who will consequently sell more copies.
I worked in bookselling in the 70s–80s and then publishing up to the early 90s (before internet advertising was much of a thing), and back then publishers regularly supplied copies of book covers to bookshops, as well as posters, etc., as promotional material. {The poster formerly known as 87.81.230.195} 94.1.208.246 (talk) 00:20, 25 October 2025 (UTC)[reply]
This does not imply that the cover art was free of copyright. The recipient of a copy of a copyrighted work may own that copy, but not the right to copy it. Museums may supply posters promoting exhibitions for free to places that are likely to display them publicly while selling them to the general public.  ​‑‑Lambiam 01:31, 25 October 2025 (UTC)[reply]
Book cover art is often contracted 'work for hire' (whose copyright is owned by the publisher), and where not, the artist will licence it to the publisher for use as promotion, which the uses DMc75771 specifies fall under. And increasingly cover art is created by publishers' own art departments, using combinations of images from picture libraries.
I suggested "they don't need to claim fair use" because although there might be a theoretical copyright infringement, in practice such usages will be expected and acquiesced to (if not actually agreed by contract) by all parties. Book-cover scans include all the typography, so it's not as if someone could feasibly re-use the image for some other purpose. {The poster formerly known as 87.81.230.195} 94.1.208.246 (talk) 17:19, 25 October 2025 (UTC)[reply]
Using easily available technology, it is often not very difficult to remove the typography. The cover shown here, of an Arabic edition of One Thousand and One Nights, is a particularly easy case. While the text is in the public domain, I am not so sure of the cover art, by Laila Yousri.  ​‑‑Lambiam 08:52, 29 October 2025 (UTC)[reply]
I'm not suggesting for a moment that such artwork is in the public domain, but rather that, whether in copyright to the artist or the publisher, the specific re-uses of covers that DMc75771 mentioned would be permitted (according to either contract, or custom) – I can assure you that publishers' legal departments are fully apprised of such usages.
If someone actually did edit and re-use such cover art for some other purpose, then I would expect the artist and/or publisher to take formal steps and if necessary legal action to stop them. {The poster formerly known as 87.81.230.195} 94.1.208.246 (talk) 05:40, 30 October 2025 (UTC)[reply]

Is Trump going to invade Venezuela or not : any serious references so far?

[edit]

Are there any serious theories proposed by experts currently, beyond the obvious illegality of the killings in the Caribbean? My personal hypothesis as a European: He is planning a land-invasion through Colombia, as a débarquement by sea isn't logistically possible. However, it is illegal for him to use the American military bases in Colombia for this type of operation and Colombia's president is opposed to US-intervention in Venezuela. So, he is preparing escalation by calling Petro a drug boss after the latter denounced the killing of Colombian citizens in the Caribbean. The military bases serve to fight the drug organisations, and Trump has declared war on "the drug cartels". Seems all very clumsily planned, and hopefully it will fail. Is there any expert agreeing with my analysis (or giving a different one), beyond just "Trump wants escalation" (which is obvious to anyone)? 2003:EE:6F16:C1A3:DE7:D7D9:1F97:50BD (talk) 15:06, 25 October 2025 (UTC)[reply]

Only Trump knows what Trump is going to do, or not do. ←Baseball Bugs What's up, Doc? carrots15:22, 25 October 2025 (UTC)[reply]
Does he? Some Trump watchers, including clinical psychologists, may disagree.[5][6][7][8][9]  ​‑‑Lambiam 19:10, 25 October 2025 (UTC)[reply]
It's possible Trump himself doesn't know. But unless he's clued someone else in, he's the only one to know, if anyone does. ←Baseball Bugs What's up, Doc? carrots22:57, 25 October 2025 (UTC)[reply]

Any serious references for this prediction or is this the fruit of diligent crystal ball gazing?  ​‑‑Lambiam 07:45, 26 October 2025 (UTC)[reply]
Not something as patently untrustworthy as a crystal ball; perish the thought. It was my ouija board, confirmed by my goat entrails and tarot cards. Also, chicken TACOs is the special of the day in my fortunetelling menu. The POTUS (in particular, the IDIOTUS) can't declare war, and the military is not as craven as the politicians (especially since it would be their lives/reputations at risk), and finally Congress will acquire some gumption once the midterms flip it from red to blue. Clarityfiend (talk) 08:17, 27 October 2025 (UTC)[reply]
On a more practical note, the logistics just isn't set up for a major conflict down there. Captain Bone Spurs, drawing on his "vast" military expertise, should know that. Clarityfiend (talk) 08:35, 27 October 2025 (UTC)[reply]
Keep in mind that he doesn't have to actually invade, he just has to threaten to invade. The art of negotiation, so to speak. ←Baseball Bugs What's up, Doc? carrots13:48, 27 October 2025 (UTC)[reply]
The United States invasion of Panama, as well as the invasions of Latin American countries during the Banana Wars, such as of Nicaragua, took place without such dispensable niceties as a declaration of war.  ​‑‑Lambiam 17:50, 27 October 2025 (UTC)[reply]

Year where computer were invented and gone mainstream

[edit]

Can you find the year on where computers were invented? I need help on find the earliest uses. When did computers start to go mainstream? UnityDecit555 (talk) 23:53, 26 October 2025 (UTC)[reply]

That would depend on how exactly you defined 'computer' (and 'mainstream'). The modern digital computer didn't spring into existence fully formed, instead it took a series of developments, and several dead ends (e.g. Babbages analytical engine, a mechanical device that would, had it been completed, arguably have been the first.) I suggest you read the article on computers you have already linked, to get a better idea of what the evolution of the modern computer involved. AndyTheGrump (talk) 00:09, 27 October 2025 (UTC)[reply]
Looking at Timeline of computing, I think 1951 is a good answer for when computers started to go mainstream: the year of the first commercially available computer, and the first two computers for business use. But there are a lot of other adjectives like electronic and stored-program that go between "first" and "commercial computer". We also have Timeline of computing hardware before 1950. If we say that the year of the invention of the first computer is the year when a computer was first working, and programmed, and was both general-purpose and intended to be used in a general-purpose way, I think the answer is 1945 with ENIAC, which means it was also electronic.  Card Zero  (talk) 02:24, 27 October 2025 (UTC)[reply]

Perhaps Punched card for an early reference to manipulation of data. DOR (ex-HK) (talk) 23:40, 28 October 2025 (UTC)[reply]

Or the Jacquard machine, which went mainstream immediately after its invention? But if we stretch the notion of "computer" that much, why not the abacus?  ​‑‑Lambiam 08:14, 29 October 2025 (UTC)[reply]

Electoral College curiosity

[edit]

Hi. Do presidential Electors, generally, know the ballot of their state where they vote for the President in December, in the Electoral College? Thanks. 37.159.42.102 (talk) 10:20, 27 October 2025 (UTC)[reply]

Are you asking whether they know who all the presidential candidates are? ←Baseball Bugs What's up, Doc? carrots13:45, 27 October 2025 (UTC)[reply]
I didn't express myself clearly. I wanted to ask if they know the type of ballot paper, they use to vote in December as members of the Electoral College, not the traditional Election Day ballot paper. — Preceding unsigned comment added by 37.159.33.160 (talk) 14:50, 27 October 2025 (UTC)[reply]
Didn't you ask this some months ago? ←Baseball Bugs What's up, Doc? carrots16:16, 27 October 2025 (UTC)[reply]
There was a similar but different question.  ​‑‑Lambiam 17:03, 27 October 2025 (UTC)[reply]
The Twelfth Amendment to the United States Constitution requires the ballots for casting a vote for President and those for VP to be separate. Other than that, there is no requirement on their form. When the electors meet to cast their votes, one may presume that – if they do not already know the form in which their ballots will be presented – they will become acquainted with the ballots during the meeting. It is not obvious that that form is already determined and fixed at the moment the electors are chosen, but one may expect the secretary of state of any given state to use essentially the same form as in previous elections if it has not presented any problems in the past.  ​‑‑Lambiam 17:35, 27 October 2025 (UTC)[reply]
I don't think this is a question about the "paper" used. I think this is a very badly translated question and the original question is if the electors know who they will vote for. If that is the question, the answer is yes. They pledge for a candidate long before voting. 68.187.174.155 (talk) 19:48, 28 October 2025 (UTC)[reply]
The original may have been scheda elettorale, which Google Translate translates as "ballot paper". I interpreted the question as not being about the type of paper, but about the form in which the ballot is presented to the electors. It will probably not be very dissimilar to the ones seen here (cast in the 2008 United States presidential election), here and here (the latter two cast in the 2016 United States presidential election) – but note the differences, which are not insignificant.  ​‑‑Lambiam 08:06, 29 October 2025 (UTC)[reply]

Does it change anything? (Sincerest apologies if this counts as a medical advice question)

I was wondering if Pectus Excavatum changes how CPR (Cardiopulmonary Resuscitation) is performed. I'm not asking how to do CPR, or how to do it on someone with the condition, but just wondering if you'd actually change the technique for it. For context, I'm talking about teens and adults with it.

A 2015 letter in Resuscitation says "Current AHA and ERC guidelines do not give any information about CPR technique (proper compression depth and hands position) in PE patients who have not had surgical correction and no cases have been reported in literature."

How can I estimate my electricity bill in Pakistan?

[edit]

Hi everyone, I am looking for ways to estimate monthly electricity bills for a small household in Pakistan. Is there any standard calculation method or formula people commonly use? Like, how do units, peak hours, and tariffs typically affect the total cost?

I will appreciate any guidance or example calculations from those who have experience with this. Thanks in advance! Caseyhunt1228 (talk) 13:50, 30 October 2025 (UTC)[reply]

Fake Vote 2 (new request)

[edit]

Hi, I am reposting my request with the hope of better luck. Now, with the understanding that the thing itself is worthless as obvious, the image in the link depicts fake Arizona electors casting their “votes” on a fake ballot for Trump in 2020. If you look at the image, I even tried to enlarge it but couldn't understand much, how were these “electors” casting this fake vote? The ballot seems drawn in such a way that maybe they had to put their signatures on it, but you can't see much. It's just a little curiosity, but I want to take it off anyway. Thank you.
