A funny thing happened when I wrote up my 2025 book list – a lot of the books were parts of pairings. And I started wondering what other pairings I had read that were memorable.
You wouldn’t know it to look at me (or would you?) but I am a person who has read all 14 books of the original L. Frank Baum Oz series. From “The Wonderful Wizard of Oz” to “Glinda of Oz” and all in between.
As… that kind of person, I was truly tickled to pick up “Wicked” a couple years ago and take in not only the invented back-story of the Wicked Witch of the West (Elphaba), but also all the references to the Oz world that Maguire builds into his narrative. “Wicked” is the best kind of reimagining, one that manages a completely fresh story, but without tearing down the original source material on the way. Maguire clearly is also… that kind of person, and he treats Oz with respect while building a totally fresh take. Loved it so much.
I came across “Longbourne” as a book recommendation from the hosts of the Strict Scrutiny Podcast (a podcast that current events renders more relevant every day). Like “Wicked”, “Longbourne” picks in the same world as the source, but manages to tell an entirely unique story that pays tribute to the original.
“Longbourn” is told entirely from the point of view of the servants in the Bennet family home. It both tells a heart warming love story, and illuminates just how different the circumstances of the upstairs and downstairs of the house are.
The version I had conveniently included both “Longbourn” and the entirety of “Pride and Prejudice” in one volume. It was crazy to read the old novel and see just how little the service staff figured in the story. And yet, as “Longbourn” makes clear, they would have been omnipresent, working hard every day, 24/7.
“James” showed up on number of “best of” lists for 2024, and I deliberately read it after doing a re-read of Huck Finn. The central conceit of “James” is that the slaves are all play acting the character of “slave” in front of the white world, but have a rich secret intellectual life they only show to one another. This makes Everett’s “James” an engaging narrator, well read, ironic at times, and observant, but no more compelling as a human being than Twain’s “Jim”.
For me, after the first third of the book, “James” did not have a lot new to offer. Everett has to work through all the narrative beats of the original material, but does not have much more to offer than the central twist. In those parts of the story where James is separated from Huck, and Everett has the freedom to write his own narrative for James, I found the story more engaging, but when he is stuck inside Twain’s story arc, the book kind of grinds along.
“March” tells the tale of the largely absent father figure of “Little Women”, abolitionist Mr. March, who heads off join the Union Army as a chaplain, and ends up having as miserable a time as one would expect, in the Battle of the Wilderness and then on a Union-occupied plantation.
I found this book on the Pullitzer list (winner for 2006) and it was a great engaging read, good for anyone interested in a little Civil War fiction that does not shy away from just how miserable an experience war is. The human wreckage of battle, the devestation of every built structure, the disappearance of civil society and law. March heads off to war thinking he can make a difference. He returns much more realistic.
The “Demon Copperhead” and “David Copperfield” pairing I wrote about before. I picked up “Copperfield” right away after “Demon” to explore all the connections that Kingsolver had built into her tale, and I was a little surprised to find out how much she’d changed. Some of her characters had no analogues in Dickens and vice versa. Parts of the plot were gone or re-arranged or had no obvious analogue. Which was all fine, since “Demon Copperhead” stands perfectly well on its own.
Also wrote about these before. Worth reading together, if only to appreciate, in Newman’s telling, just how much of a self-absorbed prig Winston Smith actually is.
For PostGIS Day this year I researched a little into one of my favourite topics, the history of relational databases. I feel like in general we do not pay a lot of attention to history in software development. To quote Yoda, “All his life has he looked away… to the future, to the horizon. Never his mind on where he was. Hmm? What he was doing.”
Anyways, this year I took on the topic of the early history of spatial databases in particular. There was a lot going on in the ’90s in the field, and in many ways PostGIS was a late entrant, even though it gobbled up a lot of the user base eventually.
I have been watching the codification of spatial data types into GeoParquet and now GeoIceberg with some interest, since the work is near and dear to my heart.
Writing a disk serialization for PostGIS is basically an act of format standardization – albeit a standard with only one consumer – and many of the same issues that the Parquet and Iceberg implementations are thinking about are ones I dealt with too.
Here is an easy one: if you are going to use well-known binary for your serialiation (as GeoPackage, and GeoParquet do) you have to wrestle with the fact that the ISO/OGC standard for WKB does not describe a standard way to represent empty geometries.
Empty geometries come up frequently in the OGC/ISO standards, and they are simple to generate in real operations – just subtract a big thing from a small thing.
If you have a data set and are running operations on it, eventually you will generate some empties.
Which means your software needs to know how to store and transmit them.
Which means you need to know how to encode them in WKB.
And the standard is no help.
But I am!
WKB Commonalities
All WKB geometries start with 1-byte “byte order flag” followed by a 4-byte “geometry type”.
enum wkbByteOrder {
wkbXDR = 0, // Big Endian
wkbNDR = 1 // Little Endian
};
The byte order flag signals which “byte order” all the other numbers will be encoded with. Most modern hardware uses “least significant byte first” (aka “little endian”) ordering, so usually the value will be “1”, but readers must expect to occasionally get “big endian” encoded data.
The way to signal an empty collection is to set its numGeometries value to zero.
So for example, a MULTIPOLYGON EMPTY would look like this (all examples in little endian, spaces added between elements for legibility, using hex encoding).
01 06000000 00000000
The elements are:
The byte order flag
The geometry type (6 == MultiPolygon)
The number of sub-geometries (zero)
Polygons and LineStrings
The Polygon and LineString types are also very easy, because after their type number they both have a count of sub-objects (rings in the case of Polygon, points in the case of LineString) which can be set to zero to indicate an empty geometry.
For a LineString:
01 02000000 00000000
For a Polygon:
01 03000000 00000000
It is possible to create a Polygon made up of a non-zero number of empty linear rings. Is this construction empty? Probably. Should you make one of them? Probably not, since POLYGON EMPTY describes the case much more simply.
Points
Saving the best for last!
One of the strange blind spots of the ISO/OGC standards is the WKB Point. There is an standard text representation for an empty point, POINT EMPTY. But there nowhere in the standard a description of a WKB empty point, and the WKB structure of a point doesn’t really leave any place to hide one.
After the standard byte order flag and type number, the serialization goes directly into the coordinates. There’s no place to put in a zero.
In PostGIS we established our own add-on to the WKB standard, so we could successfully round-trip a POINT EMPTY through WKB – empty points are to be represented as a point with all coordinates set to the IEEE NaN value.
Here is a little-endian empty point.
01 01000000 000000000000F87F 000000000000F87F
And a big-endian one.
00 00000001 7FF8000000000000 7FF8000000000000
Most open source implementations of WKB have converged on this standardization of POINT EMPTY. The most common alternate behaviour is to convert POINT EMPTY object, which are not representable, into MULTIPOINT EMPTY objects, which are. This might be confusing (an empty point would round-trip back to something with a completely different type number).
In general, empty geometries create a lot of “angels dancing on the head of a pin” cases for functions that otherwise have very deterministic results.
“What is the distance in meters between a point and an empty polygon?” Zero? Infinity? NULL? NaN?
“What geometry type is the interesection of an empty polygon and empty line?” Do I care? I do if I am writing a database system and have to provide an answer.
The trouble with empty handling is that there are simultaneously a million different combinations of possibilities, and extremely low numbers of people actually exercising that code line. So it’s a massive time suck. We have basically been handling them on an “as needed” basis, as people open tickets on them.
Other Databases
SQL Server changes POINT EMPTY to MULTIPOINT EMPTY when generating WKB.
I did a lot of reading last year, a lot, perhaps because I had a lot of down time. I tend to read before going to sleep, and recovery from surgery and other things means I go to bed early and then fill the time between bed and sleep with books. Books, books, and more books.
To be totally precise, I read books on a Kindle, which allows me to read in the middle of the night in the dark with the back light. Also to read from any position, since all books are the same, light weight when consumed via an e-reader. I am a full e-reader convert.
Anyway, I’ve had means, motive and opportunity, and I read a tonne. Some of it was bad, some of it was good, some of it was memorable, some not. Of the 50 or so books I read last year, here are ten that made me go “yes, that was good and memorable”.
I used to read Booker Prize winners, but I found the match to my taste was hit-and-miss. The Pullitzer Prize nominees list, on the other hand, has given me piles of great reads. I am still mining it for recommendations, older and older entries.
Anyways, this modern day re-telling of Dicken’s David Copperfield is set in Apallacia, amid the height of the opiod crises. The book is tightly written, has some lovely turns of phrase, and a nice tight narrative push, thanks to the borrowed plot structure. I re-read the Dickens after, because it was so much fun to mark out the character borrowings and plot beats.
This non-fiction re-telling of an original slavery escape narrative is occasionally verbose, but an excellent entrant into a whole category of writing I did not know existed, the contemporaneous slavery escape narrative. For obvious reasons, abolitionists before the Civil War were keen to promote stories that humanized the people trapped in the south, who might otherwise be theoretical to Northern audiences.
The book re-tells the escape of Ellen and William Craft, and wraps that story in a lot of historical context about the millieu they were escaping from (Georgian slavery) and to (abolitionist circles in the North). The actual text of their story is liberally quoted from, but this is a re-telling. Frederick Douglass appears in their story, which gave me the excuse I have been waiting for a long time to read the next book in this list.
One goes into books from the 1800s wondering just how punishing the language is going to be. Clauses upon subclauses upon subclauses? None of that here. Douglass writes wonderfully clean prose the modern mind can handle, and tells his story with economy but still enough context to make it powerful. Probably because as a master story teller, he was pitching for an audience much like the modern one – made up of people with little knowledge of the particulars of the slave system, just a broad and overly simple sense of the injustice. After 150 years, still devestating and accessible.
The Goodreads crew does not seem to think this book is as good as I do, but what strikes me about it and what makes me slot it into my “years best” is that I remember it so clearly. This is a historical novel of the California gold rush, from the eyes of children born to Chinese immigrants in the gold fields. It’s both an intense family drama, and an meditation on the power of place. It left me with a strongly remembered sense of the land, and the characters. Even though it covers a big swathe of years, the cast of characters remains small and their interactions meaningful. It’s memorable!
(Also, and this is no small thing, I read Into the Distance by Hernan Diaz this year too, which is set in the same time period and has some of the same beats… so maybe these books are a pairing.)
It’s a great time to be reading about authoritarianism! In the same spirit as pairing up Demon Copperhead with David Copperfield, I also paired up a reading of George Orwell’s 1984 with this retelling of the same story from the point of view of Julia, the love interest in Orwell’s book.
Newman takes the opportunity to flesh out Julia as a character and also the world of 1984 a little more, which makes the re-read of the original really fun. I do not think I noticed before just how much Winston Smith is a self-absorbed schmuck, but once you’ve seen it, you cannot unsee it.
A tragedy told from the inter-leaved view points of four members of a family falling apart. Each chapter from a different character, each builds up the point of view narrator and also illuminates the others. Mostly the reveal is who these people are, bit by bit, but the plot also slowly clicks together like a puzzle until that last piece slides in, and oh boy.
An easy engaging read that gets more and more intense, but you cannot look away.
Written by an Asian-American author, about a white author appropriating the story of an Asian-American author, the story is gripping, snarky, and unblinking in its takedown of the publishing industry. Come for the plot, stay for the commentary on modern meme-making and self-promotion, the intersection between who we are and who we present ourselves as. On the internet, nobody knows you are a dog. Or everybody knows you are a dog and hates you for it.
I don’t think this book made many or any “best of” lists, so it is not clear to me what caused me to read it, but it was a treat. Just a very quiet story about an introverted retired librarian, finding his way as he transitions into retirement, and builds some new connections with his community. Sounds really boring, I know, but I hoovered it up and it still sticks with me. A good read if you need some optimism and calm in your life.
A history of the Troubles in Ireland, wrapped around the story of a particular murder, long unsolved, that slowly reveals itself over the decades, as the perpetrators come to terms with their part in that violent chapter of history. The Goodreaders really like this one and I agree. I knew the bare minimum of this chapter of world history (what I gleaned from CNN at the time, and from Derry Girls more recently) and this telling makes an easy introduction, covering a wide sweep of time and context.
Claire North remains a lesser-known science fiction author, despite her low-key hit The First Fifteen Lives of Harry August (read it!), but I’m a convert, and this novel reminded me why. The world is a post-climate crisis culture that has achieved some spiritual and technological balance with the ecology, but is wrestling with the return of what we would describe as “business as usual” – the subjugation of the natural world to the needs of humans.
Following an ecological monk, turned spy, from inside the capital of the new humanists, through the other realms of this world is easy because the journey is wrapped in a high-stakes espionage story. Of all the climate stories I have read lately, this one taken from such a long distance in the future speaks to me most. I want to think we will build something new and better, and while I know our human nature can be malign, I also know it can be beautiful.
Best for last. Told in multiple sections from multiple perspectives in multiple styles, every narrator is unreliable, each in their own way, but the idea that there is a kernel of truth lying beneath it all never goes away (and yet, is never truly revealed). Perhaps a perfect book club novel for that reason. (Not where I got it, it’s another Pullitzer winner.)
Some facts everyone agrees on. There is a very rich and powerful financier. He has a relationship with a woman who he marries who is very important to him. But in what way? Unclear. And man is malign, but in what ways? The usual mercenary ones you might expect of a Wall Street lion? Worse and additional ways? Unclear. The whole thing is a puzzle box, the language, the characters, the events. Read it. Read it again. Read it a third time.
I was glancing at the New York Times and saw that Catherine, the Princess of Wales, had released an update on her treatment. And I thought, “wow, I hope she’s doing well”. And then I thought, “wow, I bet she gets a lot of positive affirmation and support from all kinds of people”.
I mean, she’s a princess.
Even us non-princesses, we need support too, and I have to say that I have been blown away by how kind the people around me in my life have been. And also how kind the other folks who I have never really talked with before have been.
I try to thank my wife as often as I can. It is hard not to feel like a burden when I am, objectively, a burden, no matter how much she avers I am not. I am still not fully well (for reasons), and I really want to be the person she married, a helpful full partner. It is frustrating to still be taking more than I’m giving.
From writing about my experience here, I have heard from other cancer survivors, and other folks who have travelled the particular path of colorectal cancer treatment. Some of them I knew from meetings and events, some from their own footprint on the internet, some of them were new to me. But they were all kind and supportive and it really helped, in the dark and down times.
From my work on the University of Victoria Board of Governors, I have come to know a lot of people in the community there, and they were so kind to me when I shared my diagnosis. My fellow board members stepped in and took on the tasks I have not been able to do the past few months, and the members of the executive and their teams were so generous in sending their well-wishes.
And finally, my employers at Crunchy Data were the best. Like above and beyond. When I told them the news they just said “take as much time as you need and get better”. And they held to that. My family doctor asked “do you need me to write you a letter for your employer” and I said “no, they’re good”, and he said, “wow! don’t see that very often”. You don’t. I’m so glad Crunchy Data is still small enough that it can be run ethically by ethical people. Not having to worry about employment on top of all the other worries that a cancer diagnosis brings, that was a huge gift, and not one I will soon forget.
I think people (and Canadians to a fault, but probably people in general) worry about imposing, that communicating their good thoughts and prayers could be just another thing for the cancer patient to deal with, and my personal experience was: no, it wasn’t. Saying “thanks, I appreciate it” takes almost no energy, and the boost of hearing from someone is real. I think as long as the patient doesn’t sweat it, as long as they recognize that “ackknowledged! thanks!” is a sufficient response, it’s all great.
Fortunately, I am not a princess, so the volume was not insuperable. Anyways, thank you to everyone who reached out over the past 6 months, and also to all those who just read and nodded, and maybe shared with a friend, maybe got someone to take a trip to the gastroenterologist for a colonoscopy.
