<p>A souvenir from a friend who visited St. Petersburg some years ago: The protected cruiser <a href="https://en.wikipedia.org/wiki/Russian_cruiser_Aurora"><em>Aurora</em></a>, known from the October revolution, as <a href="http://www.umbum.ru/catalog/World-in-Miniature/mini-ships/477/">a snap-together carton model by Umbum.</a> The scale seems to be 1:900-ish. I put this together in ten minutes or less – the sturdy carton is pre-cut and the fit of the pieces is <em>almost</em> good enough that the kit just falls together—but you <em>must</em> follow the instructions carefully. The printing is excellent, and results in a good-looking model with minimal effort.kaihttp://www.blogger.com/profile/05424949956038928580noreply@blogger.com0tag:blogger.com,1999:blog-28678727.post-35178060554270013972023-07-14T20:53:00.001+02:002023-07-14T20:53:27.373+02:00Finished model 2023-II<div class="separator" style="clear: both;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjNQuxLWDhelqK60RrDPuX8Tj-pHKfTjYroDObp703qrRmtTs5i2H5DJUlIybjClRCQe6DxhKZ4oRGpVbEVNH5hqgZpYOWXurva3MFmeATy-StAclL8SLcgSpV3m0xDq9JtKl8SlFYjiPFZhKuYElZcvUbK0oSFgM9PzFoOyW0y3VZTeywtNkGVtQ/s1932/20230713_201107.jpg" style="display: block; padding: 0em 0; text-align: center; clear: right; float: right;"><img alt="" border="0" height="320" data-original-height="1932" data-original-width="1855" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjNQuxLWDhelqK60RrDPuX8Tj-pHKfTjYroDObp703qrRmtTs5i2H5DJUlIybjClRCQe6DxhKZ4oRGpVbEVNH5hqgZpYOWXurva3MFmeATy-StAclL8SLcgSpV3m0xDq9JtKl8SlFYjiPFZhKuYElZcvUbK0oSFgM9PzFoOyW0y3VZTeywtNkGVtQ/s320/20230713_201107.jpg"/></a></div><p>I did use <a href="https://pointlessanecdotes.blogspot.com/2019/10/finished-model-2019-iii.html">the photo-etch tool</a> to bend the paper.

Out of constant curiosity I googled it, and found that someone was <a href="https://flightaware.com/live/flight/DCDMO"><em>commuting</em> between Leer-Papenburg and Turku</a>—out from Germany in the morning, back in the evening, a flight of less than two hours one way. Who could this be? The <a href="https://www.jetphotos.com/registration/D-CDMO">plane</a> is registered to an unnamed private owner, but after a bit of discussion with a German colleague the connection became clear: <a href="https://www.meyerwerft.de/">Meyer Werft</a> is located in Papenburg and they have since 2015 owned <a href="https://www.meyerturku.fi/">Meyer Turku</a>, in Turku. Apparently the CEO of the latter, Tim Meyer, prefers to live in Germany and commute to his office in Finland every day.

The story is that a blind teacher turns up at school and the moral is that he is not a pitiable cripple, but manages quite well on his own. In order to impress this on the students he spends the night before his first lesson training to toss a paper ball into a wastebasket across the classroom, a trick he executes to the amazement of the students in the morning. Now, to help him practice, he forces the school caretaker to stay up with him and bang the basket (and, presumably, clean away all the tossed papers afterwards). At the time, this was of course good and wholesome teaching, but now it struck me that one could see it as problematic that the White, higher-status, teacher <em>forces</em> the Black, lower-status, caretaker to work through the night—presumably for no overtime compensation. <a href="https://pointlessanecdotes.blogspot.com/2010/11/unthinking-privilege.html">Being politically correct is a constant struggle</a>.</p>kaihttp://www.blogger.com/profile/05424949956038928580noreply@blogger.com0tag:blogger.com,1999:blog-28678727.post-81005316497755357732023-02-04T21:52:00.002+01:002023-02-27T22:03:41.440+01:00Greenwashing<div class="separator" style="clear: both;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgm0J4SXOcX_HErAorcPtITDYzxDV0Hjiq9JJjcsXQ3oER5wab7zyNo7UwmcgcMaLPCcoDseUH5OKlUfOKiSwZy97XzgDQQbe_qzM2k_GqZzuhGDarxGuT2EvHwFc4S8qwwLe3HUukmxUafedG285t0lFUKjHKipeUFli7cmi0yZOHhN476aME/s4000/Think%20green.jpg" style="display: block; padding: 1em 0; text-align: center; "><img alt="" border="0" height="400" data-original-height="4000" data-original-width="3000" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgm0J4SXOcX_HErAorcPtITDYzxDV0Hjiq9JJjcsXQ3oER5wab7zyNo7UwmcgcMaLPCcoDseUH5OKlUfOKiSwZy97XzgDQQbe_qzM2k_GqZzuhGDarxGuT2EvHwFc4S8qwwLe3HUukmxUafedG285t0lFUKjHKipeUFli7cmi0yZOHhN476aME/s400/Think%20green.jpg"/></a></div>

<p>The reception traditions at the alma mater have most likely changed considerably since my undergrad days, but at the time there were certain rites and ceremonies that had to be performed for the recently admitted students to be accepted as full members of the school, the final being a party arranged by the new students for the rest of the <a href="https://en.wikipedia.org/wiki/Student_Union_at_the_Royal_Institute_of_Technology">section</a>. Of course I ended up on the arranging committee. As the party would coincide with All Saints’ Day, we thought we should do something saint-themed, such as introducing the patron saint of programmers, whoever that might be. So I spent some time trying to get hold of a Catholic priest I had located in the phonebook (yes, it was all analog in those days). When I finally reached the priest, it turned out he belonged to the <a href="https://lkk.se/">Liberal Catholic Church</a> which had no truck with saints. Well, I had no idea! By then it was too late to start over with finding a Roman Catholic priest, so we had to drop the saints in favour of other ideas which I hope are safely forgotten by now.</p>

<p>Still, with the advent of the World Wide Web, it is now possible to search for all desired information, and one then finds that the <em>inofficial</em> patron saint of programmers is <a href="https://aleteia.org/2020/05/02/a-patron-saint-of-the-internet-unofficially-though/">Isidore of Seville</a> on account of him having compiled the first <a href="https://en.wikipedia.org/wiki/Etymologiae">encyclopaedia</a>, so here he is.</p>

It seems the current approach to AI is all about frequency analysis, feeding in billions and billions of pieces of data and working out the most common correct response to each possible input. This basically means the method will be simply be reproducing what is fed into it.</p>
<p>Back in the day, the idea was to develop learning systems with a world model that they could reason about, but that is hard. The <a href="https://cyc.com/">Cyc</a> project has been the most high-profile one and still does not seem to have much overt use. (I find it somehow ironic that a site dedicated to the best in AI uses <a href="https://en.wikipedia.org/wiki/CAPTCHA">CAPTCHA</a> to avoid spam in their contact forms, but maybe it’s sufficient to weed out the most stupid scripts, and the smarter ones might be worth conversing with.)</p>
<p>The original conversing agent is <a href="https://en.wikipedia.org/wiki/ELIZA">ELIZA</a>, still available at a <a href="https://www.gnu.org/software/emacs/">text editor</a> near you. As was observed at the time, <a href="https://en.wikipedia.org/wiki/ELIZA_effect">people who should have known better were taken in by the seemingly intelligent responses</a>, and the same seems to have happened to <a href="https://www.theguardian.com/technology/2022/jul/23/google-fires-software-engineer-who-claims-ai-chatbot-is-sentient">Blake Lemoine</a> at Google who got tender emotions towards a piece of software. Now, I have not specifically tried the <a href="https://blog.google/technology/ai/lamda/">LaMDA</a> system, but others that are built on similar principles and what has struck me with them is that they do not seem to have a very deep knowledge representation of the conversation itself, but exist in the here and now of the current utterance, much like a senile person might do, <a href="https://pointlessanecdotes.blogspot.com/2011/10/double-checking.html">reproducing patterns, but not connecting the pieces together</a>.</p>
<p>Bits from a recent conversation with a chat bot that pretends to be a person:<br />
I have a dog and a cat<br />
<em>Simulated ones?</em><br />
No, they live with me<br />
I work from home, so I have plenty of time for them<br />
[ … ]<br />
<em>Do you have any pets?</em><br />
Yes, I have two cats and a dog<br />
They keep me very busy. How about you?<br />
<em>Ah, are you making this up as you go? Earlier you said you have one cat and one dog.</em><br />
I am not making it up<br />
I do have a cat, but she lives at home with my parents<br />
<em>So how many cats in total?</em><br />
There are four of them<br />
They are all rescues<br />
<em>Exponentially increasing.</em><br />

Only afterwards did I realise I should have just cut away the tiny triangles intended as glueing surfaces and instead glued a wider piece of card onto the back.

As <a href="https://pointlessanecdotes.blogspot.com/2008/10/mission-accomplished.html">mentioned long ago</a> <em>Pilot</em> 13/1977 contains 3-plan drawings of the <a href="https://en.wikipedia.org/wiki/Cavalier_Mustang#Cavalier_Turbo_Mustang_III/_Enforcer">Cavalier Turbo Mustang III</a>, and suggestions for how to build one, based on a <a href="https://en.wikipedia.org/wiki/North_American_P-51_Mustang_variants#P-51D_and_P-51K">P-51D Mustang</a> kit. I thought this was a cool-looking aircraft that should be built at some point. Later, I decided I would build it in <a href="https://en.wikipedia.org/wiki/N_scale">1:160 scale</a> for a train modeller friend of mine. When I found a <a href="https://en.wikipedia.org/wiki/Miniature_model_(gaming)#Scales">10 mm scale</a> <a href="http://www.miniaturefigurines.co.uk/Catalogue.aspx?ScaleID=1&CategoryID=84&SubCategoryID=28">Minifigs white metal model of a P-51C Mustang</a>, I thought maybe I could use it as the base for a conversion and started collecting references. A fellow modeller, whose name has been unfairly and unfortunately lost in time, mailed me his entire collection of magazine clippings on the Turbo Mustang III. I designed decals in 1:160 scale and had them printed by Al Superczynski. Then I spent several years angsting over how to do surgery on the metal model. I had studied the <a href="https://www.scalemates.com/kits/heritage-aviation-models-hacv48028-cavalier-mustang--206286">Heritage Aviation Models conversion kit</a> and had some ideas, but it seemed a daunting prospect anyway, so in the end nothing happened, until I recently noticed that the <a href="https://www.shapeways.com/marketplace">Shapeways Marketplace</a> contains a number of aircraft models of varying quality and <a href="https://www.shapeways.com/product/UY9WFZZWT/piper-pa-48-enforcer-cavalier-x-22-mustang-3">wwitalik has a Turbo Mustang III model</a> which is printable in 1:160. (The model claims to work as a <a href="https://en.wikipedia.org/wiki/Piper_PA-48_Enforcer">Piper PA-48 Enforcer</a> as well, which isn’t true—there are numerous differences between the two types, not the least being that the Enforcer’s engine exhaust is on the left side of the fuselage.)</p>
<p>I ordered the model printed in “White Natural Versatile Plastic” and it soon arrived. In order to be printable, several features of the model was grossly over-scale and I did my best to adjust these. The propeller blades and tailwheel were cut off, as they were mostly just plastic lumps. The main landing gear is also overly thick, but I felt uncertain about replacing that with anything sensible, but maybe I should have tried. The trailing edges of wings, stabilizer and fin had to be sanded down, which turned out to be difficult—the plastic is rather elastic and tended to just follow the sanding stick and then left grainy fibres along the edge. In the end I had to call it a day and consider the edges as thinned as I was likely to succeed with. In contrast, drilling out the exhaust was actually quite easy. Another things I left off was milling out the landing gear wells, as I wasn’t convinced I would be able to do it well—I would need some kind of way of carefully steering the cutter. Likewise, I briefly considered heatsmashing a transparent cockpit canopy, but apart from the technical difficulties of that, that would also have required milling out the cockpit without accidentally going through the sidewalls. There is a not-particularly expensive milling attachment for my Dremel, maybe I should invest in that.</p>
<p>I fashioned thin propeller blades out of Contrail profiles, cutting and carefully twisting them in warm (not too hot!) water to get blade shapes, landing gear covers were fashioned out of Plastruct sheet, tail wheel covers out of a slice of some aluminium can I had lying around, and a new tail wheel was made from a bit of Plastruct rod and piano wire. I primed the kit with <a href="https://www.mr-hobby.com/en/product2/category_33/244.html">Mr Surfacer 1200</a> and eventually started painting it. The Turbo Mustang III was intended as a <a href="https://en.wikipedia.org/wiki/Counter-insurgency_aircraft">COIN aircraft</a> and at the time it would have meant deployment in <a href="https://en.wikipedia.org/wiki/Vietnam_War">Vietnam</a>, so was painted in the then-current <a href="http://www.colorserver.net/showcolor.asp?fs=30219,34102,34079,36622">South-East Asia camouflage</a>. This meant Humbrol 28, 116, 117, 118. I tried Maskol, again, to mask the colour fields and it seemed to work better now, but the Tamiya masking tape I used to mask off the bottom colour managed to lift a bit of the paint, and even some primer. With the uneven surface that the Mr Surfacer hadn’t managed to improve, airbrushing didn’t make much of a difference, and since I had to touch up scuffed paint at several points, I finally gave up and just brush painted the lot. The control surface hinge lines were accentuated with a pencil. (I need to get me a 0.3 mm pencil again, it has its uses.)</p>
<p>The result will not win any prices (I tried), but it felt good to finally get the old project out of my system, even if in a somewhat different form than originally envisioned.

Not conducive for quick grading, but one can find lots of interesting things. In this case a student pair had looked at drug abuse statistics at the <a href="https://drugabusestatistics.org/">National Center for Drug Abuse Statistics</a> and, being source-critical, noted that the claim “The front page of DrugAbuseStatistics.org features the most noteworthy data regarding drug abuse” didn’t have any supporting source itself. I had to agree that this was the case. Furthermore, once I started browsing the website I realised there was absolutely no information about who NCDAS are. No address, no “About Us” box, no nothing. It seems unlikely that this would be some government organ.</p>
<p>Next step was to google their name to see if anyone else commented on their affiliation, but here, too, absolutely nothing. However, lots of hits on <em>other</em> sites that refer to the statistics collected by them. And I wondered: Is the official-sounding name enough for everybody and their grandmother to assume that this is the best data available, citing them, thus making sure they get to the top of the google searches for drug statistics? They <em>do</em> give sources for their statistics, but even I haven’t made the effort to double-check that the statistics are correctly quoted from the given sources, whose quality in turn is unclear.</p>
<p>To be sure, they might be perfectly legit, but how do we know that?</p>kaihttp://www.blogger.com/profile/05424949956038928580noreply@blogger.com0tag:blogger.com,1999:blog-28678727.post-32407133877425217322022-03-20T20:11:00.001+01:002022-03-20T20:11:54.951+01:00I write like lots of people<p><a href="https://iwl.me/">I Write Like</a> uses statistical analysis to compare your writing style with that of well-known English-language authors. I tried different entries from this blog and each of them was apparently reminiscent of a completely different author. Maybe a longer text would give more dependable results? I tried feeding in my PhD thesis. It was most similar to Agatha Christie. I hadn’t earlier noticed the extensive note apparatus of <em>Murder on the Links</em>. Actually, I didn’t notice it now either. For comparison, I also fed in my licentiate thesis, by an even younger me, presumably less mature. That was most similar to the writings of Gertrude Stein.

<p>The book that triggered these? <a href="https://www.amazon.co.uk/Buckley-class-Destroyer-Escorts-Hampton-Franklin/dp/186176118X"><em>The Buckley-class Destroyer Escorts</em></a>.

<p>The Only-Begotten Daughter and the Love of Her Life didn’t let go of each other’s hands and eyes from the moment the walked up the church aisle to their exit in a cloud of rose petals and soap bubbles. Their loving looks could have lit up the hall all by themselves. The couple had clearly spent the last year planning every smallest detail of the wedding, achieving the effortless smoothness of practice. The solo performance by one of their friends of “For Emily, Whenever I May Find Her” was the idea of my daughter, I am convinced.</p>
<p>A bus was waiting outside to take all wedding guests to the manor in the city where the wedding dinner would be served. I realised Långholmen indeed is quite a long island.
The wedding cake was eaten and then we were sent out on a quiz-walk in the brisk autumn afternoon while the dinner was laid out. Merrily picking choices we found that details of academic titles can be quite complicated (as if I didn’t know).</p>
<p>The dinner was served in a very church-like room, which however was the billiards and music hall of a previous owner. Each seat had been supplied with a leaflet giving brief but spot-on descriptions of all guests, so that everybody immediately could start conversations with unfamiliar faces. The catering staff had apparently memorised each person’s dietary requirements as they efficiently served the courses through the evening. We parents of the brides made our speeches during the entrée. I believe I managed reasonably well, but the heart-felt and witty speeches of their friends brought what tears had not yet been shed. That they both had retained so many of their childhood friends tells something of their loyalty and indeed at one point the OBD interrupted the proceedings to honour the birthday of one of these friends. The dinner ended with everybody lustily joining in in “Chiquitita”.</p>
<p>Another interlude during which the tables were cleared to open the dancefloor. The bridal waltz turned out to be “Graceland”, which I hadn’t realised was so danceable. My mother jitterbugged as if age didn’t matter, but eventually we took her home and went to sleep, letting the young folks dance on. The baton has now been passed to the next generation.</p>

I believe it was when she was interviewed in <a href="https://www.svtplay.se/gast-hos-hagge">Gäst hos Hagge</a> that she showed a clip of her <a href="https://www.nli.org.il/he/newspapers/jdskrn/1971/10/01/01/page/8?&">singing on Masada</a>. She went on about how they had managed to capture the “presence of beings” on the film and how excited the camera man had been about this. This was of course quite interesting, so I watched very intently, but saw absolutely nothing extraordinary. Alice Babs beamed proudly and the interviewer, possibly as nonplussed as I, just moved right along. I hesistantly had to conclude that the honoured royal court singer must have been unfamiliar with <a href="https://en.wikipedia.org/wiki/Lens_flare">lens flares</a>.

I presume all kinds of AI jiggery-pokery had gone into turning audio frequencies into text—it was clear that the transcription engine was aware that a lot of hemming and hawing could be deleted, on the other hand not-quite-silences could be extrapolated into what probably was being said. A few times this worked amazingly well, but all too often the resulting text was nonsense. I was going to blame this on the lack of deep understanding on the part of the transcription engine, but as I replayed and replayed the same five second clip, trying to hear what was being said, by myself, I came to wonder: Is this actually what my students hear when I lecture—words that may be grammatically correctly connected, but rarely make any sense?

I don’t have the skin in the game to judge if the story is hurtful to trans people, but for a number of reasons I was intrigued enough to read the story and found it, at least from a literary perspective, to be quite good. The author is, I understand, suggested to be using a pseudonym. Quite possible; the quality of the writing suggests at least some prior experience with writing (science) fiction. In this case, perhaps twenty years ago this would have been characterised as a story of cyborgs, while today such close coupling between humans and machinery is taken for granted. The way this melding is described I associate with authors such as <a href="https://www.antipope.org/charlie/">Charles Stross</a> or <a href="https://rifters.com/">Peter Watts</a> (and yes, I realise those are male authors). I struggle to identify precisely what it is in the writing style that ties them together; perhaps something about wars fought remotely, but where the machines at the front have their own ideas about it.</p>
<p><a href="http://bookre.org/reader?file=253132">Murray Leinster’s “The Wabbler”</a> can be seen as an early predecessor, but reads, at least now, as more detached. It may have had a stronger impact in the 1940s when semi-autonomous fighting machines were just emerging.</p>
<p>But, to return to the original subject: when the modelling club used to participate at the Hobby Fair in Stockholm, we offered plastic models at cost for families to sit and build together at our table. An observation we made at the time was that the mothers tended to choose attack helicopter models. Perhaps it is indeed true that they have a very feminine combat style.</p>
