Lihavuusleikkaukseen

Päivitys: Kirurgin sairastumisen takia leikkaukseni on siirtynyt. Leikkauspäivä on 5.10.2015. Alkuperäinen blogahdus alla:

Menen 31.8.2015 Lahden keskussairaalaan lihavuusleikkausta varten. Leikkauspäivä on 1.9.2015.

Käsittääkseni tarkoitus on tehdä mahalaukun ohitusleikkaus. Tässä operaatiossa mahalaukku leikataan kahtia. Ruokatorveen kiinni jää pieni pussukka, joka yhdistetään suoraan ohutsuoleen. Loppuosa mahalaukusta jätetään kiinni ohutsuoleen, mutta se ei enää vastaanota ruokaa. Tämä johtaa annoskokojen merkittävään pienenemiseen ja tuottaa kylläisyyssignaalin huomattavasti aiemmin kuin leikkaamattomalla mutta vaikuttaa ilmeisesti myös hormonaalisesti; moni leikattu kertoo makuaistin muuttumisesta leikkauksen jälkeen. Mikään ihmeratkaisu tämä ei ole. Tulen myös leikkauksesta takaisin noin suunnilleen samanpainoisena kuin sinne menin.

Tutkimuksissa [mm. 1, 2] on havaittu merkittävä ero kokonaiskuolleisuudessa sekä muissa olennaisissa mittareissa (mm. painonlasku, diabeteksen eteneminen) leikattujen ja leikkaamattomien välillä leikkauksen eduksi. Tämä on minulle tärkein syy ryhtyä tähän hommaan.

Leikkaus tehdään tähystyksenä ja johtaa muutaman viikon työkyvyttömyyteen.

Kommentit ja kysymykset tervetulleita, mutta olkaa lempeitä, sillä aihe on arka.

Bariatric surgery approaching

Update: Due to the surgeon being ill, the surgery has been moved back to October 5, 2015. The original blog post follows:

I will be checking in to a hospital for bariatric surgery on August 31, 2015. The surgery is scheduled for September 1.

The plan is to perform the roux-en-y gastric bypass (RYGB), in which the stomach is cut into two pieces. A small pouch is left connected to the esophagus, and the rest of the stomach is cut off from the food flow. A Y-connection is created in the small intestine, allowing both parts of the stomach to connect to it. The main result is a reduction in meal sizes, accompanied with a faster fullness signal and apparently some hormonal changes; some people have reported a change in their taste sense after the surgery. It is not a miracle cure, and I will weigh about as much when I leave the hospital compared to when I enter it.

Studies [e. g. 1, 2] show a significant reduction in overall mortality and improvement in several relevant outcome measures (such as weight loss, diabetes status) in favor of surgery compared to nonsurgical weight management techniques. This is my main motivation for undertaking this surgery.

The operation will be laparascopic and will require several weeks of recuperation time off work.

Comments and questions welcome, but please, be gentle. This is a touchy subject.

How a wrong model can lead you astray

The other day I got on a bus at the downtown main bus terminal. Behind me, a woman started to interrogate the driver.

“Do you go to Pohjantie?”

When the bus driver did not respond (likely, he does not remember all the names of the roads on his route), she changed tactics:

“Your sign says Kuokkala. Which route do you take?”

There are three roads to Kuokkala, which is on the other side of Lake Jyväsjärvi: two drive around the like on opposite sides, and one takes a bridge over the lake. One of the drivearounds in fact goes through Pohjantie (as well as a neighbourhood called Tikka), and several buses take that route. Buses also use the bridge; to my knowledge, no bus uses the other driveraound route.

“On the way back I’ll go through Tikka.”

“So you end up at Viherlandia?” Viherlandia is the terminus of one of the bus routes that drives through Pohjantie.

“No.”

“But Kuokkala, how do you get there?”

“I’ll take the bridge, then drive around the Kuokkala centre and then turn right …”

“… toward Nenäinniemi. You’re not my bus, thanks.”

In fact, she was wrong; it would have been her bus had she waited to hear the bus driver’s reaction to Nenäinniemi; he wasn’t going there, instead, he would have just turned to Tikka and from there through Pohjantie back to downtown.

But I suspect she had a mental model: all buses in Jyväskylä run (so she probably thought) pendulum routes, going back the same route they take. So, once she had established that the bus took the bridge, she had all the information she thought she needed.

In fact, that particular line runs a mixed pendulum and ring model: going Northeast from the downtown terminal, it runs to a particular suburb and retraces its steps back to downtown; however, southbound, it goes over the bridge to Kuokkala and drives a semiring route in Kuokkala, existing through the Pohjantie drivearound and making its way back to the downtown terminal.

People sometimes say that science is objective and empicial, and that the data speak for themselves. This sort of a statement forgets that data mean nothing by themselves, and your conclusions are no better than your model.

The Imitation Game

Viewed on its own terms, The Imitation Game is a good enough entertaining film among many such. It has suspense, romance, and triumph in all the right proportions, all according to the formula. Breaking the pattern, it also tackles the treatment of gays in the 1950s, as well as the kind of social awkwardness very common among geeks and highly intellectual people. Although the film does push some of my triggers (one scene in particular I was only able to watch about three seconds at a time, pausing the film in between), that’s not the film’s fault.

But the film is not just any other film. It depicts Alan Turing’s life, and in large part dramatizes the codebreaking activities at Bletchley Park during the Second World War. Viewed in this light, the film disappoints. Certainly, a film needs drama, and while codebreaking at wartime is crucial, the suspense involved is too abstract to sustain a film alone; thus, the filmmakers were justified in adding interpersonal conflict to the mix, to inflate the role of Turing at Bletchley Park, and to emphasize Turing’s attachment to coworker Joan Clarke. But where they come up short is that they did it in such a formulaic manner. I am not very good at guessing plots, and I was able to guess large parts of this film (beyond what I knew of Turing’s life). Clarke, who was a capable mathematician in her own right, was cast (based on the historical record, true) in this movie in the role which in any other movie I would call the token love interest, but in this movie that label seems off.

Benedict Cumberbatch gave a suberb performance as a very eccentric Alan Turing; I have nothing negative to say about his work in this film. But that’s to be expected; he is, after all, one of the great stars of my generation. I was more impressed with Alex Lawther’s interpretation of the young Alan Turing. Keira Knightley brought Joan Clarke to life in an unforgettable manner, though I do wonder how much that is due to her and how much is due to Clarke being the only significant female character in the movie. The other actors, however, were rather forgettable.

Alan Turing certainly deserved to be given his own film. Although the movie is wrong to state that we call Turing machines computers nowadays, Turing’s work certainly is foundational and fundamental to all of computing. And, true enough, he is a war hero. In the end, I enjoyed the film, and it certainly deserved to be made. Therefore, ★★★☆☆.

[Edited to add words about Knightley’s performance and about Clarke’s formulaic role.]

Sharon Lee & Steve Miller: Dragon in Exile

I will not bow to ignorance

In this brand new Liaden novel, Clan Korval deals with the consequences of its actions. Not everybody on Surebleak want them there, and not all Liadens are willing to treat with them honorably now that the Council of Clans on Liad no longer counts Korval as a member. The Department of Interior still poses a threat, and Korval must figure out what to do with the agents they captured. In the most part, however, Dragon in Exile is a tapestry woven from many small threads, most following the mundane (and sometimes not so mundane) lives of one or two characters each.

There’s the story of the exquisite rug that a Liaden clan had been meaning to buy and now adorns a whorehouse. And there’s the baker who says no to an insurance salesman. Oh, and what happens when a busful of tourists attempt to use the tickets they bought offworld to actually get to visit Korval’s Tree? There’s several arsons; an attempted armed revolution; and, oh, I almost forgot, a wizard who becomes addicted to his own magical powers.

Dragon in Exile includes a prologue of the “previously in this series” variety, though it is framed as a bona fide scene in the book. Likely the prologue will be useful for the new reader of the series, and I think a new reader will catch on quite well with this book. Readers already familiar with the series will get added richness and texture, of course.

Audible calls Dragon in Exile Book 1 of the Arc of the Covenants. The arc title is nowhere to be seen in the print and ebook editions, but it does make a certain amount of sense given certain scenes in the book and it does point to an interesting direction for the rest of the five-book dash that this book starts.

Kevin T. Collins narrates here his first “modern” Liaden book. I still like him a lot as a narrator, but his pronunciation is in places jarring, as it differs markedly from that used by other narrators.

I enjoyed this book immensely. And with this, my re-listen of this series is complete. It was fun, and I will do it again at some point. And I will re-read the books myself occasionally ­– my inner voice is unlike all the narrators.

Dragon in Exile is available as a hardcover paper book, an ebook, and as an audiobook.

Steinerkoulu on 12-vuotinen, ei 9-vuotinen

Luin tänään uutisen Jyväskylän steinerkoulun lukiovaiheen lopettamisesta. Minusta se on surullista. Steinerkoulu on 12-vuotinen yhtenäiskoulu, ja jos oppilas on valinnut kyseisen koulun, on harmillista että sen joutuu lopettamaan kesken oman halunsa vastaisesti. Tilanne on jatkossa sama kuin minkä koin itse vuonna 1993: muutin 9. luokan jälkeen Tampereelle toiseen steinerkouluun. Tarkoitus oli kai kaikilla, että olisimme jatkaneet Jyväskylässä, mutta valtioneuvosto epäsi lukioluvan. En ole lainkaan varma, että lasta kannattaa laittaa steinerkouluun, jos kaikille on tiedossa, kuten nyt, että koko steinerkoulun käyminen tulee vaatimaan myöhemmin paikkakunnalta muuton.

Mainittakoon muuten, että en ole koskaan tykännyt ilmaisusta “steinerlukio”. Steinerkoulu on steinerkoulu, vaikka sen yhteydessä voikin suorittaa lukion oppimäärän ja ylioppilastutkinnon.

Sharon Lee & Steve Miller: Fledgling

The major export of planet Delgado is higher education and scholarship. Not everybody on the planet likes this, and an significant minority of the nonacademic population are “simples”, who abhor complexity and look for ways to return to simplicity. The eradication of the University of Delgado is one such way.

A professor of Delgado is discovered to have falsified her data. More alarmingly, it is discovered that the certified copies of the original archives she used, which are held by the university, have been tampered with. Sub-Chair Kamele Waitley of the History of Education Department must act decisively to discover the full extent of this sabotage.

Her daughter, Theo Waitley, is used to living in the off-campus house of her mother’s onagrata (registered lover), Gallowglass Chair Professor of Cultural Genetics Jen Sar Kiladi (who we have already met in earlier books in the series). Suddenly, Kamele moves back to a traditional scholar’s apartment at the campus, taking Theo with her and to all appearances ends her relationship with the man Theo calls Father. Theo does not like it at all, but she has no real choice. But when Kamele takes her offworld, to an expedition where Kamele and her team intend to find out exactly how bad the sabotage is, everything changes.

Fledgling has a curious history. Back in 2007 or so, the then-publisher of the well-established Liaden series went bankrupt, taking with it the near-term rights to the existing books and the royalties the authors had recently earned on them. The authors had to scramble. One of the ways of making money they came up with was to publish a first-draft novel, straight from the word processor, so to speak, a chapter a week, so long as the readers kept donating a reasonable sum per week (300 dollars, if I recall correctly). They expected, I understand, to have weeks off due to the slowness of the donations’ flow, but were surprised: the full book was funded very early on. So they kept their promise, and posted a brand-new hot-off-the-word-processor chapter each week. I had just finished my first read of the series as it then existed, and followed the web serial as it unfolded. A couple of years later, when the Liaden rights had been released from the old publisher’s bankruptcy, Baen picked up the series and published Fledgling (with significant edits ­– recall, the web serial was a first draft by intent) as its first Liaden offering.

I have a love-hate relationship with this book. I really hate the young Theo who is the narrator for most of the book (she does eventually grow up, and becomes much more fun a character in the later parts of the series). The kinds of problems she has early on are really cringeworthy. Well written, mind you, but I sure don’t like to be reminded what the teens were like. However, I really love the second plot involving Sub-Chair Waitley, Gallowglass Chair Kiladi and others who essentially become self-appointed detectives in order to solve a mystery that potentially could ruin the whole planet. I also love the introduction to pilot-lore we get through Theo when she gets off planet and starts encountering non-Delgado people and mores.

I should probably write a whole separate post comparing and contrasting the academic environments depicted in this series. Fledgling certainly has one of the most detailed (and realistic) academic environments of the series, but I think a deeper discussion will have to wait for that other post. However, I will mention the rather curious female chauvinism of Delgado, which is perhaps a bit too blatant for my taste but certainly is an effective commentary on the traditional male privilege in our present-day culture.

Fledgling is the first Liaden audiobook narrated by Eileen Stevens. She is really well suited for this book; her voice works very well with a young woman as the lead narrator and it also deals quite adequately with the elderly professors on display.

Fledgling is in print and also available as an legal free ebook. There is also an audiobook.

Sharon Lee & Steve Miller: Conflict of Honors

He raised his glass to his lips. “And what brings you to apply for work on the Passage?”
“I don’t have any choice.”
The slanted brows pulled together. “Has Mr. Saunderson still got that impressment operation going? I did ask him to stop, Ms. Mendoza, I give you my word.”
For the third time in an hour Priscilla felt laughter rising. She drowned it in a swallow of wine. “I’m sorry—that was rude. What I meant to say was that I’ve been—dismissed—from my post on Daxflan. Yours is the only ship in at Jankalim now, so I’m applying here.”

There is this problem with the reading order of the Liaden series if you want to start with the original 1980s books. Agent of Change was the first, and its direct sequel is Carpe Diem, which was the third. The second book, Conflict of Honors, is a prequel to the two others and introduces characters that play a supporting role in Carpe Diem. The first time I read these books, I read them in publication order, leaving the cliffhanger at the end of Agent of Change unresolved for the duration of Conflict of Honors; it distracted me from this book and made it less enjoyable for me. Some people advise reading Conflict of Honors before Agent of Change, which certainly is a logical reading order, but I personally prefer to start with Agent. Therefore, I now skip Conflict of Honors entirely and come back to it at some later point in a rereading sequence. Like now.

Conflict of Honors is a good, leisurely introduction to the universe; I can easily see why some people recommend it as the book to start with. The principal character is Priscilla Delacroix y Mendoza, a Terran citizen. She being Terran, her attitudes and expectations are fairly familiar to the typical reader, that is, not particularly alien. She gets herself involved with Liadens, and particularly becomes entangled with Liaden balancing of accounts (a form of honor feuding), and thus, as she is educated about the Liaden culuture, we are, as well.

The book is, from another angle, a healing book. Priscilla starts as a young woman who has survived much abuse and is quite scarred because of it. She joins a ship whose crew is considerate and loving people, who show her the path to healing and to realizing her full potential.

A detail that I find adorable: big ships in the Liaden universe appear to carry pet libraries. That is, they carry animals which crew and passengers may lend out for a period of time. That is a concept one might want to see introduced into the real world.

“Do you really need a pet librarian?”
“Well, we didn’t have one,” he said, spinning the screen toward her. “So I guess we do. Palmprint here, please.”

Another joy of the book is the character of Shan yos’Galan. He is quite ridiculous but also sharp as a knife. And I find that I enjoy the portrayal of him given by narrator Andy Caploe, who I otherwise find unsatisfactory.

Conflict of Honors is in print as part of the Dragon Variation omnibus, which is also available as an ebook. There is a standalone audiobook.

Sharon Lee & Steve Miller: Scout’s Progress / Mouse and Dragon

This pair of books tell one story, another space regency romance.

Aelliana Caylon Clan Mizel is terrorized by her older brother the nadelm. For example, her mandatory contract marriage that produced her heir was arranged by that same brother to a man who raped and brutalized her. At one point, years later, she comments: “of course marriage is—extremely—distasteful”. She is safe, for some values of safe, by the word of the current Delm. But nadelms become delms, in the fullness of time.

Aelliana Caylon is also known to all pilots as the mathematics scholar who revised the ven’Tura tables used by pilots to determine safe jumps from star-system to star system, and is credited with having thereby saved countless of lives. Her research area is chance event – that is, card games and things like that. She teaches, among other things, a course in practical mathematics to scouts – a course the scouts call “math for survival”. However, due to her family history, she is utterly fearful of other people outside of the classroom.

One night, she happens to end up at the opening of a new casino at her home port. Goaded by some of her students, she observes the play and notices that one high-stakes player is playing a faulty system. She remarks upon it, and finds herself playing against him. She stakes her quarter-share, he stakes her ship. It is no spoiler to let you know that Aelliana wins the ship, for that is only where the story really starts. She now has a plan: learn to pilot, learn Terran, and leave Liad before the nadelm becomes the delm and kills her.

This shall be Korval’s Balance: As of this hour, the ships of Korval and of Korval’s allies do not stop at Ganjir. Korval goods do not go there; Korval cantra finds no investment there. And these conditions shall remain in force, though Ganjir starves for want of us.

…I note that my mother is still dead.


Daav yos’Phelium
Eighty-Fifth Delm of Korval
Entry in the Delm’s Diary for Finyal Eighthday in the first Relumma of the Year Named Saro

Daav yos’Phelium is Korval Himself. The duty weighs on him, and he from time to time hides his ring of office and becomes just plain Daav, casual labor at Binjali Repair Shop at Solcintra Port. He happens to be there when a woman comes to ask for a copilot, she being so new to her license as to need certified flight time on her record; to his astonishment, he learns her to be Aelliana Caylon, the reviser of the ven’Tura tables. But he is, of course, happy to sit her second board.

To tell much more of the two books surely would be a spoiler. I will merely note that they tell a remarkable growth story with Aelliana Caylon as the protagonist, and that everyone who had read the rest of the series – and the authors, I understand! – were really afraid of the second book, which was written more than a decade later, because everyone knew what event that book would have to cover.

As I noted in my previous blog post, these space regencies are emotionally hard for me, but these two are much easier despite having much more cruelty in them.

Bernadette Dunne’s narration continues to be a joy. I particularly enjoy her Aelliana Caylon.

There is perhaps a lot more that I would like to say about these books, but some of them are spoilers and I am too tired anyway, so I am stopping here.

Scout’s Progress is in print as part of the Dragon Variation omnibus, which is also available as an ebook. There is a standalone audiobook.

Mouse and Dragon is available on paper, as an ebook and as an audiobook.

Kuplia

Vuosituhanteen alkuvaiheilla minulle oli itsestään selvää, että kaikki järkevät ihmiset äänestävät vihreitä.

Kun Effin kokouksessa joskus muinoin ehdotin kirkkain silmin (tämä oli kauan ennen kuin Piraattipuoluetta oli edes keksitty), että ruvetaan aktiivisiksi vihreissä koska sehän on tietenkin tietoyhteiskunnan kannalta paras puolue, sain kummallisia katseita. Se oli kai ensimmäinen järkytykseni.

Toinen järkytykseni taisi olla, kun minulle selvisi, missä puolueessa isäni oli ehdolla vuoden 2004 kunnallisvaaleissa. Minä ja äiti olimme molemmat vihreitä, isäni demari.

Kolmas järkytykseni oli, kun aloin tajuta ettei kaikki työkaverini äänestä vihreitä. Samaa sarjaa oli, kun tunnistin nimeltä joitakin kommunistien ehdokkaita.

Mutta tiedättekö, suurin järkytykseni oli, kun vuoden 2011 eduskuntavaalien aikaan tutustuin vaalipiirilautakunnassa perussuomalaisten edustajaan. Sehän on ihan tolkun ihminen!
