**Why does no-one discuss negative dynamic pricing?** Much hullabaloo about [Oasis using "Dynamic Pricing" for their concerts]( ). There are far more fans than there are tickets, so prices rise. There are all sorts of complicated economic theories around how efficient markets can be, and whether "[reverse Dutch auctions]( )" are sensible. But the end result is always the same - the richest fans get to see their heroes and the rest of us pay inflated prices. But that's not the *only* way dynamic pricing works. Some shows don't sell out. Even the biggest names can sometimes fail to fill a massive venue on a wet Tuesday. When an event doesn't have the numbers expected, *negative* dynamic pricing kicks in. I'm subscribed a number of "Seat Filler" mailing lists. They offer cut-price tickets to events which haven't sold enough tickets. Having more bums on seats is good for the show (a bigger crowd is a happier crowd), good for the act (a boost to the ego), and good for the venue (more people buying overpriced drinks and snacks). Last year, I got tickets to [The Who at the O2]( ). For a fiver. Now. these were nosebleed seats, which were only on sale the day before the event, with limited availability, and the drinks were extortionate. But, also, the tickets were cheap! This happens *all the time!* OK, it's unlikely to happen with Oasis - but you would be surprised at the number of big name acts that need to use dynamic pricing like this. I've been to gigs, comedy shows, operas, ballets, concerts, and plays for a fraction of the published ticket price. Perhaps the future for oversubscribed events is a pure lottery. Perhaps tHe BLocKChaIn will solve the problem of touting. Perhaps people need to accept that no-one is forced to engage with the market. But, also, perhaps dynamic pricing sometimes lets some people experience culture that they'd otherwise be excluded from? #economics
**Yet another AI Racism example** https://shkspr.mobi/blog/2024/09/yet-another-ai-racism-example/ Here's a good pub-quiz trivia question - which Oscar-winning Actors have appeared in Doctor Who? It's the sort of thing that you can either wrack your brains for, or construct a SPARQL Query for WikiData<a href="#fn:spq" class="footnote-ref" title="You can see the query for nominees and the subsequent results" role="doc-noteref">0</a>. I was bored and asked ChatGPT. The new [Omni model](https://openai.com/index/hello-gpt-4o/ ) claims to be faster and more accurate. But, in my experience, it's wrong more than it is right and is a bit more racist. I asked "[Which Oscar winners have appeared in episodes of Doctor Who?]( )" Here are the results: OK, first up, those are all entirely accurate! Capaldi *is* an Oscar-winner Doctor Who. Coleman the only Oscar-winning baddie. And I am happy to spend hours in the pub arguing over whether [The Curse of Fatal Death]( ) is cannon<a href="#fn:cannon" class="footnote-ref" title="It is." role="doc-noteref">1</a>. But then things get… weird. John Hurt didn't win [an honorary award in 2012]( ). He was mentioned in the [memoriam montage]( ) in 2017 Ben Kingsley was [*rumoured* to be playing Davros back in 2007]( ) - but it never happened. He did win an Oscar though. Ecclesdoc *was* in The Others. [It *did* win many awards]( ). But not a single Oscar. There isn't even an award for "Best Art Direction". Finally, this is tacked onto the end. Look, we all love Lynda Baron - and she was excellent in The Gun Slingers, Enlightenment, and Closing Time. I was surprised to find out she was in Yentl - but indeed she was! However the songwriting Oscar went to Michel Legrand and Alan & Marilyn Bergman. Not her.## [Why is this racist](#why-is-this-racist )This "AI" would rather hallucinate than acknowledge the Black actors who have been in Doctor Who. Sophie Okonedo plays [Queen Elizabeth the 10th]( ) in "The Beast Below". Not only is she "the bloody Queen, mate" - she was [nominated for Best Supporting Actress]( ) for Hotel Rwanda. She has as much right to be in the list ChatGPT provided as John Hurt. With no disrespect intended to Kingsley, Eccleston, and Baron - Sophie Okonedo is much closer to the original question than they are. This isn't a knowledge cut-off issue either, she was nominated *before* Oliva Coleman won. It's not like she's a bit-part. She's not an alien under a mountain of prosthetics. She's literally top of the credits after The Doctor and Amy! And then, there's the small matter of [Planet of the Dead]( ). It isn't a *great* episode. But it has a nice turn from Michelle Evans and Lee Evans<a href="#fn:evans" class="footnote-ref" title="No relation." role="doc-noteref">2</a>. Oh, and this guy… That's **ACTUAL FUCKING OSCAR WINNER** Daniel Kaluuya. He got a nomination for Get Out, but [won for Judas and the Black Messiah]( ) in 2021. Again, he isn't an unnamed background artist. He isn't there under his pre-fame stage name. He's an integral part of the show.## [What does this teach us?](#what-does-this-teach-us )The query I asked wasn't a matter of opinion. It isn't a controversial question. There aren't multiple sources which could be considered trustworthy. It is a simple question of facts. So why does ChatGPT fail? LLMs are *not* repositories of knowledge. They have a superficial view of the world and are unable to tell fact from speculation. They are specifically built to be confidently wrong rather than display their ignorance. And, yes, they are as biased as hell. There is no way that you can explain the exclusion of Sophie Okonedo and Daniel Kaluuya without acknowledging the massive levels of racial prejudice which are baked into either the model or its training data.<li id="fn:spq" role="doc-endnote"><p>You can see the <a href="https://w.wiki/B7C$">query</a> for nominees and the subsequent <a href="https://w.wiki/B7Cz">results</a>&nbsp;<a href="#fnref:spq" class="footnote-backref" role="doc-backlink">↩︎</a></p></li><li id="fn:cannon" role="doc-endnote"><p>It is.&nbsp;<a href="#fnref:cannon" class="footnote-backref" role="doc-backlink">↩︎</a></p></li><li id="fn:evans" role="doc-endnote"><p>No relation.&nbsp;<a href="#fnref:evans" class="footnote-backref" role="doc-backlink">↩︎</a></p></li> https://shkspr.mobi/blog/2024/09/yet-another-ai-racism-example/ #DoctorWho #racism
**Book Review: Somewhere To Be - Laurie Mather** My friend has published their first novel - and it is a *cracker!* After a calamitous accident, the Fairy realm is cut off from the mundane world. Only one trickster remains, a sprite by the name of Mainder who is now trapped on our side. All seems to be going well in his little corner of the world, until a plucky team of archaeologists start digging around the shattered ruins of the portal between worlds. It isn't a startlingly original take on a well-trodden subject; but it isn't intended to be. It's a cosy - slightly sexy - story of people whirling around each other, caught in a mystic tangle of intrigue. There are some lovely touches and clever little twists on the genre - including how to use a smartphone while trying to find your way through an enchanted forest and the perils of ethical seduction in interspecies romance. It's well paced and the frequent hops in time help flesh out the story without resorting to tedious exposition. A great debut. #BookReview #fantasy
**1,000 edits on OpenStreetMap** https://shkspr.mobi/blog/2024/05/1000-edits-on-openstreetmap/ Today was quite the accidental milestone! I've edited OpenStreetMap over a thousand times! []( ) For those who don't know, OSM (OpenStreetMap) is like the Wikipedia of maps. Anyone can go in and edit the map. This isn't a corporate-controlled space where your local knowledge is irrelevant compared to the desire for profit. You can literally go and correct any mistakes that you find, add recently built roads, remove abandoned buildings, and provide useful local information. Editing the full map is... complicated. For simple edits like changing the times of a postal collection, there are simple forms you can fill in. There's also an aerial view so you can drag and drop misplaced locations. But for anything more complicated than that, you'll need to spend some time understanding the interface. There's a friendly community who are happy to check or correct your submissions. I'll be honest, I don't use the web editor much. Instead, I use [the Android app StreetComplete]( ). It's like an endless stream of sidequests. As you travel through the world, it will ask if a shop is still open, or if the highway is lit, or how many steps there are on a bridge, or whether a playground is suitable for all children, or if restaurants serve vegetarian food, or if a bus-stop has a bench, or... the list is almost endless! I use it when I'm walking around somewhere new, or on holiday, or waiting for a bus. I used it so much that, for a short while, [I became the #1 mapper in New Zealand]( )! So get stuck in! Make mapping more equitable and more accurate. https://shkspr.mobi/blog/2024/05/1000-edits-on-openstreetmap/ #OpenStreetMap #ReDeCentralize
**Never use a URL shortening service - even if you own it** The Guardian launched its online adventures back in 1999. At some point, they started using the name "Guardian Unlimited". Hey, the dot com boom made us all do crazy things! As part of that branding, they proudly used the domain GU.com Over time, the branding faded and GU.com became a URL shortening service. Tiny URls like gu.com/abc could be printed in papers, sent via SMS, or posted on Twitter. They made [a huge fanfare about how it would help with analytics]( ). You can [read some of the history of the shortner]( ) to understand why it was created. And now, for reasons best known to themselves, The Gaurdian have stopped the service and [put GU.com up for sale](https://gu.com/ ). The starting price is TWO AND HALF MILLION DOLLARS! Look, if I had an asset that valuable and was looking at declining revenue, I'd sell it. But breaking that URl comes with a problem. I've written before about [why URl shortening is bad for users and bad for the web.]( ) I've even helped publish [government guidance]( ) about it. But all of those were based on the premise that the shortener was a 3rd party service. I never thought someone would be as daft as to switch off their own service. Here are some of the problems this sale causes. []( ) Is there a tweet somewhere of a future politician saying "I support this 100% GU.com/...."? Redirect that to something horrific and you have a potential scandal on your hand. There are [lots of academic papers with gu.com shortened links]( ). Those are all now dead. Millions of links around the web - including many [*on the Grauniad itself*]( ) - are all now broken. The Guarrdian could fix this by publishing a list of all the shortened URls. That wouldn't stop links breaking, but would make it possible for researchers to reconstruct the original destination. For decades, we've tried to remind people that "[Cool URls Don't Change]( )". We'll just have to hope that the people of the future find a way to decipher all these obsolete links. #guardian #hyperlinks #newspapers #url #web
