 Here's some of what you missed at The Thirsty Robot:

Technical Musings - Prisoner's Dilemma

How do people behave in a situation when they gain by co-operating, but gain more by not co-operating? This is the basic scenario of a mind game that is known as the 'Prisoner's Dilemma' where individual betrayal is rewarded higher than mutual co-operation. If you thought that altruism would win over selfish self-interest, then unfortunately, it seems that you would be wrong most of the time. There are many sources of this, and other similar 'Social Psychology' / Philosophical /  'mind games (thought experiments...) that reveal how people behave - but usually not why!' activities on the InterWeb. it is also used in MANY TV game shows...


For a VERY deep rabbit hole - try this: 

What seems to be happening is that a lot of people are convinced they were taught that 'Dilemna' is the correct spelling (The author of this text included!), even though it has NEVER been (which is why every spell checker and dictionary will show the 'mn' version as a mis-spelling (and autocorrect simply turns the 'mn' into 'mm' without asking). Even more curious, the same strangeness also happens in French, with the word 'Dilemme' or 'Dilemne'.

Diner's Dilemma - a variant for diners who agree to split the bill...


 


Another rabbit hole is that there are lots of these types of thought experiments. Hey, one moment, why are these things called 'Rabbit Holes'? 


Some examples... - Caution: you may encounter extreme time-wasting via this link...

Media Musings - Bob Fosse

Bob Fosse?

If you are younger than a certain age, then you've probably never heard of him. But then, when you search and find out, you then wonder why you didn't know. It's an interesting paradox...


All That Jazz - an autobiographical musical...

You may have heard of these musicals/films, though:

Musicals:

The Pajama Game (1954)
How to Succeed in Business Without Really Trying (1961)
Sweet Charity (1966)
Chicago (1975)

Films:

Cabaret (1972)
Chicago (2002)

Most people's jaws drop for 'Chicago' and 'Cabaret', so don't feel embarrassed!

Time Machine - Does the World Really Change Over Time?

Things change over time, often subtly and gradually, and frequently without many people noticing. It seems that these changes could well reflect larger changes in society...

Argos, the catalogue shop, was previously a trading stamp collection shop for the Green Shield Stamps that were given by supermarkets and other shops instead of discounts. Stamps were collected and stuck into books, and then full books were exchanged for items - perhaps not unrelated to Second World War ration books. The Argos model just completely bypassed the stamps!

Petrol stations used to give small household items instead of discounts, so loyal customers would gradually acquire sets of glass tumblers, crockery, mugs... Some chains of petrol stations tried other variations, like coins based on sporting events: the World Cup, for example. Or even Green Shield Stamps... Over time, price seems to have become the dominant differentiation, and loyalty seems to have become devalued. 

TV game shows used to give real physical items as prizes: cars, boats, TVs, microwaves, washing machines, bicycles, etc. Intangibles like holidays and other entertainment event tickets were also used as prizes. Some game shows were even based on knowledge of the actual price of the items. Over time, money prizes replaced real things or holidays, Apparently because people preferred to buy things that they wanted instead, which probably says a lot about the affordability of the items. When a colour TV is rare, then having any colour TV has huge prestige value, but when everyone has a colour TV, then prestige comes from having a larger, more expensive or better featured version.

Investments - Property 

Do house prices always rise faster than anything else? What is the long term performance like? Before the InterWeb, then questions like this could be difficult to obtain reliable answers for, but now...

A lot of discussion happens at The Thirsty Robot. This blog is an edited, biased summary of just a small fraction of the conversation, links/URLs and references that were mentioned. It is an imperfect record and is definitely not complete - for that you should visit The Thirsty Robot!

The next online meeting at The Thirsty Robot is on a Thursday in 2 weeks time in 2021 at 7:30pm GMT.

 Here's some of what you missed at The Thirsty Robot: Technical Musings Technology Topic - Nostalgia & Alternative Universes Maybe it was the recent Summer Solstice, or the change of weather from 'too hot' to 'unsettled', or the leak of Windows 11 , but The Thirsty Robot attendees were in a nostalgic mood. Microsoft's 'Bob' user interface was mentioned, because it is one of those fascinating 'roads almost travelled' that is probably dominant in an alternative universe - but not this one. The idea of making a computer a 'simple to use' device is an old idea, but there are few good implementations...  So, Bob was the classic 'use simple, familiar metaphors' approach. In this case, the inside of a house, where rooms were devoted to various tasks: https://en.wikipedia.org/wiki/Microsoft_Bob   This was back in 1995, and so high resolution, lots of colours and many other 2020's 'standards' just didn't exist then.

January 2022

January .   The first month of the year. The Thirsty Robot is now going to publish the summary every month, although this one is late! So, here is a short summary of some of what you may have missed in January's online meetings at The Thirsty Robot: Photo by KOBU Agency on Unsplash Ads in Games When the idea of adverts in games was first proposed, people thought that all it would mean would be that advertising hoardings in city racing games would have real adverts on them. Or billboards at sports events? Perhaps sponsorships? As always, the future is often stranger than you can imagine. Having video adverts that play in between levels, for example? Adverts for other games inside games?  https://en.wikipedia.org/wiki/Advertising_in_video_games https://www.rapidfire.com/blog/the-three-types-of-in-game-advertising/ But putting those adverts into games is also interesting. You may have never heard of an Ad Network, but these are how adverts get placed into very precisely targette...

December 2021

Dec ember.   The final and twelfth month in the year, although that 'dec' at the start of the name looks like it is something to do with the number ten. As was mentioned last month, The Thirsty Robot is now going to publish the summary every month, although this one is again very late! So, here is a short summary of some of what you may have missed in December's online meetings at The Thirsty Robot: Warning, warning... Where is Will Robinson when you need him? And did the  Netflix 'Lost In Space'  reboot robot kind of use the iconic: 'Danger, Will Robinson!' catch-phrase from the  original (there was one!) series  visually when its head-display went red? ('Reboot robot' is a gorgeous phrase,btw!)  But, anyway, continuing the theme of visual warnings: https://www.etsy.com/shop/UnsafeWarnings Photo by Breana Panaguiton on Unsplash Yep - a classic 'Thirsty Robot' topic! Warning signs for things that the official ones seem to have somehow overlo...
