Book Review: Amazon DynamoDB - The Definitive Guide, by Aman Dhingra and Mike Mackay
Over the years I've preferred to find out about new tools and techniques by reading a book about them. For quite a while, I'd been looking for a book on DynamoDB, but none worth taking seriously seemed to show up, as if this mode of learning had gone out of fashion (despite books on other NoSQL databases being readily available). I came across this recent release rather randomly, by searching without much expectation.

This covers the necessary ground, and it does so competently. To me, DynamoDB is difficult to classify among the varieties of NoSQL - is it a key-value store or a document store? It leans more toward the former, but with some features of the latter. The book gives various examples of the operations that can be performed, including through the use of the AWS console and the NoSQL Workbench tool, with a good description of the billing models available.

A fair amount of the book is dedicated to database design, with contrasts drawn from the more conventional normalization of RDBMS schemas. Secondary indexes are explained, with the pros and cons of the local and global options. There's some material on the internal architecture of DynamoDB, which is interesting but perhaps not directly relevant. More advanced topics include backup and restore, change data capture (CDC) streams, caching and multi-region operations. The final chapter on migrations is particularly practical, including some cases where DynamoDB may not be a good option. This book feels like it fills a gap in the market, and gives a pretty good grounding on the database.

Book Review: Sea of Poppies, by Amitav Ghosh
This had been on my to-read list for many years; in fact I forget how it came to be there. As such, it was a genuinely unexpected gift.

I found the structure unusual: several apparently unrelated plot lines are interspersed, yet they inexorably spiral together in misfortune. Deeti's husband works in an opium factory in rural Bengal; Neel Rattan Halder is a Raja in Calcutta; Zachary Reid is a carpenter bound for adventure from Baltimore; and Paulette Lambert is the orphaned daughter of a French botanist estranged from his homeland after its revolutions. In a strangely dispassionate way, Ghosh shows how India had been ubiquitously distorted and corrupted by the opium trade: not only the disastrous health effects brought on by addiction, but also the military-industrial complex of its time, the economic and agrarian ruin wrought by bending everything to be subservient to producing a monoculture, and the calling in of real debt when imaginary money suddenly becomes unavailable. Benjamin Burnham, of course, sees it all in terms of Free Trade - and that freedom must be forced upon China, if necessary. The Ibis is a former slave ship, and there's little doubt that Burnham would have run the ship for those purposes without compunction, in an earlier age.

There are some characters in the book who do seem to be bad people, but there's an ambivalence to more of them, and yet more are simply victims of their circumstance. Ghosh gives humanity to them all, which is effective and at times unsettling. This book is from 2008, but if anything some of the themes of exploitation, division and injustice seem even more relevant and urgent through the lens of today; I suppose a sign of the timeless quality of the writing. So much is connected: this clearly relates to Babel, which I was reading about a year ago, as well as to the more recent The Silk Roads.

Book Review: The Silk Roads - A New History of the World, by Peter Frankopan
The subtitle here is important. I was anticipating a history of the trade routes between Europe and China, through central Asia, and whilst there is some of that in here, the title is almost misleading. But, once I had got over that, it was nevertheless an interesting read. Frankopan (who turns out to be the same age as me) begins by pointing out that the world map he had as a child was largely ignored in the history he was taught at school. I dropped history before GCSE, but I recognise the sentiment, and whilst I think it's reasonable to begin locally, there ought to be wider perspectives.

There are some interesting ideas and the reader is certainly invited to think for themselves in drawing together various threads in the book. In the west, Persians, Greeks and Romans come and go. In the east, the Mongols are the dominant raiders. Jews, Christians, Zoroastrians and Muslims form alliances of convenience and then fall out, repeatedly. Europe - certainly north and west of Rome - is an irrelevance (I remember Norman Davies' history of the continent implied much the same in its introduction), although it is also a source of slaves.

Then Asia gave Europe the Black Death, and in return Europe gave the world the Renaissance, and discovered America. This gives us a few hundred years where the focus of the book pivots in a way I hadn't really expected. The sprawl of the British empire - in both hard and soft power form, often working with local client regimes of variable probity - has taken over more or less everywhere of importance by the end of the nineteenth century.

Then oil was discovered in Iran, in huge quantities. The local regime (see above) had negotiated a deal (you can guess how balanced the deal was) with the British for exploitation of oil resources, a pattern that was mirrored across the region in coming decades, through two World Wars where oil was of massive strategic importance. Post-war, Britain was more or less bankrupt and couldn't sustain the gratuities required to keep those increasingly unstable regimes in power. But then the Americans came along, and fearful of the potential influence of the USSR, made the whole situation even worse. Und so weiter. Spoilers. Somewhere along the way, there was a cheap and lazy (and incorrect) jibe about the EU accounts (I note today that the UK's National Audit Office declines to sign off our own accounts), which was irritating and in any case barely material to the wider story. The book covers the Islamic revolution in Iran through to the demise of Bin Laden in some detail, and it did leave me feeling that the last 70 or so years have been a complete car crash in the region, but also with little idea of how that could realistically have been avoided. Certainly, food for thought.

Book Review: Betjeman's England, by John Betjeman (edited by Stephen Games)
In some ways this is a companion piece to Trains and Buttered Toast; following on from that collection of radio talks, these are transcripts (or writings relating to) some of his TV programmes from 1949 through to the 1970s.

What comes over particularly well, I think, is Betjeman's good cheer, even when he's not all that taken with something. I suppose he was angry about the Euston Arch and the threat to St Pancras (neither of which feature here), but here modernity is tolerated with mostly amused resignation; I suppose the medium of television lends itself to people-watching as much as expounding about architecture. It seems particularly ironic (and in equal measure foresighted) that he grumbles about Beeching closures and the implacable advance of the motor car, when a number of the programmes were sponsored by Shell and National Benzole.

The title of the book, whilst not exactly misleading, hides the fact that the map view shows that the chosen pieces fall largely south of a line from the Severn to the Wash, with only a handful of places around Manchester and Yorkshire in the North. Additionally, Betjeman visits Glamorgan, Jersey, and the Isle of Man, and there's a passage from Panorama of him being interviewed by Malcolm Muggeridge about plans for an underground car park near Edinburgh Castle, in which he also discusses the traffic problems of Oxford - it's not mentioned directly, and perhaps the piece is a little too early, but maybe he was thinking of the infamous scheme to put a road through Christ Church meadow.

The highlight in the book for me is Metro-Land, and it prompted me to dig out the DVD for a re-watch. It's interesting to compare the written and spoken versions: in the introduction Games makes a point on the difficulty of deciding when to use prose and when to use blank verse. Inevitably one hears Betjeman's voice while reading, so it's always lyrical, but the verse sections become more regimented on the page, in a way that is not so clear on the film.

Book Reviews: The Kalahari Typing School for Men; The Full Cupboard of Life; and In the Company of Cheerful Ladies, by Alexander McCall Smith
A second batch of the No 1 Ladies' Detective Agency series. With the main characters established, things seemed to be going off the boil detection-wise by the third book in the series, and that feeling continues in the next two books. Mma Makutsi is the focus of The Kalahari Typing School for Men, both in her entrepreneurial spirit, but also more darkly in her unconditional caring for her brother with "the sickness"; her own romantic life has its ups and downs, while Mma Ramotswe handles yet another case of Men Behaving Badly. The Full Cupboard of Life struggles through with its absurd plot lines, but In the Company of Cheerful Ladies the author reboots, and there's some serious and satisfyingly gripping developments and quandaries.

In other words, much as I thought earlier, here and here.

Book Review: The Island of the Day Before, by Umberto Eco
I started reading this at the tail end of my holiday, and it took a couple of weeks to get through. I expected it to be heavy, with Eco playing with the reader, but even so, it was nearly 200 pages before it really got going. Or did it? It started to go, and might have made something of it, and then it stopped again, descending into raving. Roberto de Grive is a minor noble who, after losing his father in a rather inconsequential siege, finds his way to Paris and falls in with a louche crowd, whereupon he manages to fall foul of Church authorities, who determine that he can redeem himself by sailing incognito on a mission to the other side of the world, learning the secrets of that mission. However, we begin with his survival of a shipwreck; he clambers on board another apparently deserted but adequately provisioned ship. Within sight, but out of reach, is land where, he comes to believe, in a rather misunderstood way, it is the day before.

Eco clearly had a plan, with multiple layers: the author himself, narrating from the writing of Roberto, part diary, part romantic fiction on the subject of his love and his imaginary, nemesistic brother. But either I don't have the literary references, or it's just too oblique, for much of it to make sense. It just felt like Eco was repeatedly pushing away from completing a journey, of any sort, with more and more absurd diversions. Ultimately, the conclusion makes sense, but in a rather empty, resigned way. The only sense of achievement was in having seen the book through to the end, which is disappointing, because at times it felt that the story could actually have been about something.

Book Review: The Selfish Gene (1989 edition), by Richard Dawkins
Genes are chemicals, and whilst one might describe a chemical as "wanting" to do something in the context of a reaction, I find Dawkins' anthropomorphisms a bit much here. Underneath that layer, though, there are some interesting points to be found in the book - for example, that humans are the only species who often die of "old age", and a relatively unusual species in that we sometimes fight our own kind "to the death". But genes, really, are just complex fragments of chemicals, and some do better in the environment in which they find themselves than others, and over time, those ones proliferate. There's no intent to it. Sometimes, that environment can be influenced beneficially by other genes, and a kind of symbiosis can emerge; at other times, proliferation of one gene becomes counterproductive and a metaphorical pendulum swings in another direction. But the genes themselves aren't consciously playing game theory; Dawkins focuses on the Prisoner's Dilemma in depth, because it offers an explanation for some evolutionary journeys. I can't help feeling that this use is a biological example of a hidden variable theory, that the iterative behaviour over generations is a long random walk towards thermodynamic equilibrium, which averages out empirically in a way that looks like the game. This makes game theory a useful tool in this arena, but not one to be overdone as a full solution. Dawkins is honest enough to admit a couple of mistakes in the original edition, although these are only apparent if you read the endnotes and they could perhaps be more prominent as they do affect the argument.

Book Reviews: The No 1 Ladies' Detective Agency; Tears of the Giraffe; and Morality for Beautiful Girls, by Alexander McCall Smith
I think it was a couple of years ago that I was in a conversation with some colleagues about books and TV box sets. I asked whether they binge-read on books in a series, and the consensus seemed to be affirmative. It's not something I have generally done, tending to interleave my reading. But I thought perhaps it might work well for a re-read of this series, so I took the first three in turn.

Original reviews are here, here and here, and I think I'm broadly in agreement with what I wrote then. I knew more or less what to expect, although after twenty years(!) some of the detail was a bit hazy. There's a bit more "domestic" in book one than I had remembered; perhaps that's because it's filling in the back-story for Precious Ramotswe and so it didn't become intrusive the way I recall it in later books. And I think the second book also holds up well. The third is perhaps running a little low on steam, and I decided I would pause the series here, although I intend to return to it shortly.

One thing that did strike me on a re-read is the way Alexander McCall Smith uses opportunities to contrast Botswana society and values with European / western ones. Mma Ramotswe thinks, for example, that it is her duty as someone of reasonable financial standing to employ a maid, a role that is really a live-in housekeeper. I see the advantages, but beyond the cost there's also the loss of independence and privacy, and it's just an icky idea to me; had I grown up accustomed to that model no doubt I would think differently. The redistributive element ought to be accomplishable by taxation and the provision of good public services, although it doesn't seem to work out that way. The human problems that Mma Ramotswe's business deals in are, of course, universal at the fundamental level, but they - and often their solutions - manifest in a distinctly African way.

Book Review: The Baltic Story - A Thousand Year History of its Lands, Seas and Peoples, by Caroline Boggis-Rolfe
Unusually, I stumbled upon this randomly in Waterstone's and decided to indulge my curiosity. We've visited a few places on or around the Baltic over the years, and I hoped this might stitch some things together. I think it succeeded in that.

In the introduction, Boggis-Rolfe announces that the flow will be more or less chronological, and that each chapter will be self-contained, so there may be some repetition when reading from end to end. This was true, but it wasn't irritating, as it had been called out earlier. She begins with a brief overview of the Hanseatic League, but most of the book focuses on the various royal households, their shifting allegiances, skirmishes and borders over the years. Initially, Poland and Denmark were the major powers in the region, later usurped by Sweden and Russia, and later still by Prussia. England would often come to the aid of one or other country - it felt like never the same one twice, perfidious Albion indeed - and Napoleon stormed through most of the region, only then to be beaten all the way back. (In a bizarre sub-plot, one of his generals began the Bernadotte ruling dynasty of Sweden, arguably more successful in the long term than Bonaparte himself.) Norway and Finland changed hands between their more belligerent neighbours, and for a time Poland vanished off the map altogether. Among the lesser-known conflicts, I am now better acquainted with the Lingonberry War; and whilst I claim no expertise, I gained a bit of background on the Schleswig-Holstein question.

Book Review: The Gustav Sonata, by Rose Tremain
This was either a book swap shelf or a second-hand purchase. It is a long time since I read The Road Home, but I remember it fondly, so I was curious to read another book by the same author. Gustav and Anton grow up in a small town in Switzerland in the years after the war. Gustav is brought up by a single mother, and it's a loveless home; Anton is a musical prodigy in a wealthy Jewish home. Gustav's mother resents the Jews, but it's not clear why; it has something to do with his father's death.

Tremain then chooses to back-track to the late 1930s and early 1940s, filling in the relationship between Erich and Emilie Perle. Erich was deputy police chief in the town, and among other tasks, was at times responsible for handling the paperwork of Jewish refugees. Although not directly related to his death, it links to an inflection point and a decline in the relationship.

In the final part, Tremain fast-forwards to the 1990s. Gustav and Anton have been successful in their respective ways, though they are perhaps not always happy about it. Gustav runs a hotel, and Anton has become a music teacher. Some truths need to be discovered.

I found one or two episodes in the book disturbing and not necessary to the plot, but overall Tremain draws the story together successfully. There is a resolution of sorts, but nothing quite takes the form expected, like the real world.

Book Review: Those Angry Days - Roosevelt, Lindbergh, and America's Fight Over World War II, 1939-1941, by Lynne Olson
This was already on my to-read list before being impressed by Last Hope Island by the same author, and Philip Roth's counterfactual account of the 1940 US election, The Plot Against America. Olson begins with a summary of the early life and career of Charles Lindbergh. To be honest, he sounds a bit like Elon Musk: gifted perhaps, but socially awkward, tone deaf, and adamant in his own opinions. For his part, Roosevelt arrogantly overstretched himself in attempting changes to the Supreme Court, and became politically cautious as the situation in Europe deteriorated.

There were many motivations for isolationism, some more honourable than others. But there were also campaigns in favour of intervention, and the country was divided. In practical terms, the armed forces were in no great state either, and US laws prevented the export of war materiel to belligerents. Olson explores the various causes and campaigns, and the reluctance of Roosevelt to act or lead. The work of British and German diplomats and intelligence operations in the US was particularly interesting; and in fact although the GOP might have been largely isolationist, their candidate for the 1940 US election, Wendell Willkie, differed little from Roosevelt on matters of foreign policy. Ultimately, Roosevelt was led by others, and his hand was forced by Pearl Harbor. There is irony as well as inevitability in the fact that this event united the country. Olson presents what is evidently a complicated story in a coherent manner.

Book Review: You're Him, Aren't You? - An Autobiography, by Paul Darrow
Perhaps more so than Tom Baker's autobiography, this reads like an audio book, or perhaps a conversation with the author, or the character with whom he is forever associated. It is, however, interspersed with more warmth and generosity to other people who passed through Darrow's life. It's not a particularly long book, but Darrow combines a conventional autobiography with his own perspective on the story of Blake's 7, including an inimitable episode-by-episode guide, and the various abortive attempts to relaunch it. This is definitely a book written for the fan audience, although it covers his entire career; but the main point, is that it's well written.

Book Review: Nathaniel's Nutmeg - How One Man's Courage Changed the Course of History, by Giles Milton
This was a surprise Christmas present, so I approached it with an open mind. For the most part, the book is about the battle between European powers - principally the English and Netherlands East India companies, though the Spanish and Portuguese also feature - during the sixteenth and seventeenth centuries in their hunt for and conquest of the Spice Islands in what is now mostly Indonesia. Nutmeg in particular was sought after, promised to ward off the all too regular bouts of plague and other diseases rampant at the time. Various ventures were proposed; as well as the journeys around Africa and India, there are chapters on the unsuccessful expeditions to find North-East and North-West passages.

Beyond the sense of adventure, the other thing that emerges is the sense of lawlessness. It feels like the book has a bit of a focus on English piracy in particular, though other nations' seafarers probably engaged in that too. If you had better weaponry it was fair game to stop and plunder another ship's cargo. In the islands themselves, each company sought to carve out exclusive deals with the indigenous populations for the spice trade, and on this count it is the Dutch who are reported as being especially barbarous, both to indigenous populations and to other European traders.

It's an interesting and worthwhile read, but I think the author is stretching things a bit with the title. For one thing, said Nathaniel Courthope has a relatively small role in the book; for another, connecting that causally to the final twist in the tale feels a bit dubious.

Book Review: The Subterranean Railway, by Christian Wolmar
I bought this as a Kindle special offer before Christmas, in case I needed filler, but it had been on my radar for quite some time. This is an updated edition, with references to covid but with the Elizabeth Line still a work in progress. As I have come to expect, Wolmar is an excellent writer, and he gathers and selects his comprehensive story well, beginning with a number of transport schemes of varying plausibility that were drafted from the early nineteenth century onwards. What is remarkable is the speed of construction, once a decision to go ahead was made. Of course there was no health and safety to be concerned about, but the technology for the "cut and cover" subsurface lines was innovative, and the deep tubes which followed a generation later even more so. Despite scepticism (and smoke), the trains were generally popular, but mostly struggled to recoup their costs and pay dividends to investors. Ironically, the solution was often to build more railway, and there's no doubt that whilst central London shaped the initial routes, the later extensions into outlying villages shaped the London of the twentieth century, most famously but not uniquely with Metro-land.

The City of London was resistant to railways, and so all the main line termini lie outside its boundaries; the original Metropolitan line ran from Paddington to Farringdon, on the edge of the city, via Euston, St Pancras and King's Cross. For many years, some through trains were also allowed; Wolmar does not elaborate much, but it turns out that GWR had adopted standard gauge (or at least mixed gauge) on some routes into Paddington by 1863, which would otherwise have been a mystery. Although London Underground and National Rail services were separated many years ago, today's Thameslink service running north-south is a reincarnated example of a route originally plied by many operators.

It's not just about the trains, though. Wolmar discusses the distinctive architecture, the companies, the driving personalities, poster art, Harry Beck's map, and the development of London. The tube was used as a shelter in World War 1, as well as more famously in World War 2. In the post-war decades, investment ground to a halt, with the rise of the motor car but without foreseeing the problems of congestion, and the service deteriorated (Wolmar singles out the King's Cross fire as a particularly bad example of decline). But still there was innovation: the Victoria line introduced essentially driverless trains (they are manned for safety, rather than as a technical requirement). The Jubilee line was introduced to relieve congestion on the central section of the Bakerloo line; the subsequent extension was not that originally planned, being somewhat influenced by the Canary Wharf development (a factor also in the route of the later Elizabeth line). Financially, the system went through mergers, mutualisation, nationalisation, and PFI: some of these were more successful than others. A curious omission, I suppose falling mostly after publication of the original edition, is any discussion of modern ticketing: Oyster was innovative, and I've read elsewhere that TfL, if not the originator of the technology, arguably precipitated mass usage of contactless payments across the world. But it's still a fine book.

Book Review: Brigantia, by Adrian Goldsworthy
When I began reading this series, I enjoyed the characters of Ferox and Vindex, and considered the story somewhat as a Roman crime novel. Being honest, the series has taken a different direction, being more military and violent, following the political scheming and shifting alliances between rebellious Britons and conspiratorial Romans. Although I enjoyed aspects of this novel, in particular the bewilderment of Ferox and his provincial companions as they venture around Londinium, I found it hard to keep all the characters and plots clear in my head, and it became a bit of a slog through predictable traps, incarcerations, druidic rituals, and one battle after another. I believe it's the end of the trilogy, but it did not feel as though all the loose ends had been tidied up.

Book Review: A More Perfect Heaven - How Copernicus Revolutionised the Cosmos, by Dava Sobel
This was a makeweight on an Amazon order. It turned out to be rather odd in format, containing a two-act play in the centre, surrounded by a more conventional narrative. This was a worthwhile experiment, but it didn't really work for me; it wasn't The Life of Galileo. Copernicus, born in Torun, was a canon at Frauenberg in Prussia. His heliocentric ideas began around 1510, but it was only towards the end of his life, when he was visited in 1539 by a German mathematician, Georg Joachim Rheticus, that he was compelled to publish his work. Typical for the era, the religious schism between Catholicism and Lutheranism is prominent, and in addition, Copernicus fears the backlash his ideas will provoke. In the play he is, however, adamant about his ideas and doesn't want them phrased ambiguously for publication. Reception of the book is muted: for a few, it is remarkable, for others, it provides a convenient model for improved calculations, and for yet others, it is heresy. Interestingly, On the Revolutions never quite makes it to the banned books list of the Catholic church, because of its convenience in adjusting the calendar; instead, a list of neutering "corrections" is issued. The rest is history.

Book Review: Politics on the Edge, by Rory Stewart
When I first became aware of Rory Stewart, probably during his days as a diplomat in Iraq or Afghanistan, I thought he was a curious and probably affected combination of pragmatism and naïve and other-worldly idealism. Over the years, not much has changed about my view, although I remove the affectation; whatever it seems to me, I think it is his genuine persona.

This memoir is of his years as a Member of Parliament, including various roles in government, and it has those same qualities. Selected for a safe seat almost by accident, as so many became available in 2010 following the expenses scandal, he was never particularly popular within the parliamentary party and quickly became disaffected at the Westminster establishment and the impotence of backbenchers. His initial years in DEFRA and the Ministry of Justice (as Minister for Prisons) are written up as if he was baffled by the internal opposition of the civil service to the Minister doing anything at all. Yet he doesn't once refer to Yes Minister, as if, despite finding himself in a textbook example of the situation, he was unaware of the programme: I find that apparent blind-spot baffling even for someone who wasn't a career politician.

The later sections of the book narrate his career highs during Theresa May's premiership, through to the downfall of Boris Johnson's. The description of his leadership campaign is initially joyous but becomes somewhat self-serving: in particular, it's all but spelled out that the BBC killed off his campaign by the format of their final leadership debate, although the Conservative Party membership would almost certainly have rejected any "Stop Boris" candidate anyway. His reflections on the state of politics are confirmational rather than revelatory, but it's still an interesting read.

Book Review: Eggs or Anarchy, by William Sitwell
I had never heard of Fred Marquis, who ran the Lewis's department store chain before becoming Lord Woolton in 1939 and being appointed Minister of Food by Neville Chamberlain in April 1940. He continued in position when Churchill took over, although neither of them especially rated each other. Sitwell's biography gives a portrait of an interesting figure, focused on delivery and with no concern for bending rules or conventions when necessary, doing deals with third countries that would have raised eyebrows in normal circumstances. Much of the ministry itself was based in Colwyn Bay, to offer some protection from attack or invasion. The position was inevitably a regular target for the media, with wartime rationing and frequent supply problems, but Woolton understood the value of positive coverage and propaganda, and took every opportunity to get his messages across. Inevitably, there is a chapter on the Battle of the Atlantic; food shipping was a heavy casualty. Woolton also pursued a ruthless policy against the Black Market. His insistence that there was no such large scale market may be true, but there were many small scale instances, and sometimes officials employed a heavy-handed approach that got them into trouble. What interestingly emerges from this book (published in 2016) is, in fact, how much Churchill resembles Boris Johnson - wanting to be popular, shying away from difficult decisions, not sticking by his own rules, and so on. Woolton regularly berated Churchill for diverting shipping away from food use to military purposes, and had some success in negotiating more food capacity. Churchill moved Woolton in late 1943 to become Minister of Reconstruction, which is where the main thread of the book ends, although there is a discussion about the health of the nation during the period of rationing, and also some first-hand recollections with perspectives from shopkeepers of the period.

Book Review: Learning Domain-Driven Design, by Vlad Khononov
A few years ago I had a fairly indifferent reaction to the original DDD book; a colleague who is more enthusiastic has been passing a copy of this around the team. It's been a tricky few months at work, with some technical and team changes that I don't like, so I inevitably approached this with some scepticism, whilst trying to keep an open mind. There are some things to agree with, like ubiquitous language, but even that is challenging in practice, in a large organisation with legacy of any size. Bounded contexts and aggregates ought to make sense, but the flexibility about granularity starts to weaken the argument, because it opens scope for disagreement. I found the argument about layered architecture versus ports and adapters particularly weak. To me it's presented confrontationally, and the exposition of the ports and adapters idea is thin, unclear, and lacking good examples. Microservice Patterns offers a better discussion on this area in my opinion. Ports and adapters still require layers in my view, it's not an either/or. The discussions on CQRS and event-sourcing were clearer; the similarly named, but totally different, practice of event storming, seemed full of contradictions and unlikely to lead to consensus. I'm afraid, with the exception of event-sourcing, it didn't really move the dial for me.

Book Review: Via delle Oche, by Carlo Lucarelli
This is the final part of the De Luca trilogy. It is 1948; there is no explanation of how we got here from The Damned Season, but we can infer from De Luca's position in the vice squad that his rehabilitation has been limited by those now in power. Inconveniently for those in authority, a death occurs in a brothel in Bologna and therefore De Luca has some legitimate interest. The official line is suicide, but De Luca highlights the farcical shortcomings (literally) of this theory. It is election season, and the police are on edge (and potentially in the pockets of one or other political grouping). Deaths pile up and De Luca stubbornly persists, despite attempts to reassign him elsewhere. The conclusion is ambivalent: De Luca has a solution to the case, but whether justice will be served in any form, or whether an alternative prescription will be found, more to others' liking, is uncertain.
