Review: Poseidon’s Wake by Alastair Reynolds

Poseidon's Wake (Poseidon's Children, #3)Poseidon’s Wake by Alastair Reynolds
My rating: 4 of 5 stars

Poseidon’s Wake is the third volume in the Poseidon’s Children series by Alastair Reynolds. The events of this book are set a few centuries in the future from the second book – On The Steel Breeze. The main protagonists are still part of the Akinya clan. We find Mpozi, Goma and Ndege on Crucible and Kanu in the Solar System.

The book explores the results of the arrival of the Watchkeepers and the aftermath of the Mandala event at the conclusion of “Steel Breeze”.

Let me be honest – I found the book hard going, yet worthy of the four stars I have given it. There are long passages meditating on the meaning of life and the role of belief. Stay well clear if you are looking for action scenes or military science fiction. This is very much in the vein of Existence by David Brin. We have a McGuffin – vast alien artefacts on the planet Poseidon. The plot revolves around separate expeditions from the Solar System and from Crucible to the hitherto unvisited system following the receipt of a mysterious transmission.

Along the way, we find the machine civilisation explored in the first two books, we find super intelligent elephants as well as inscrutable aliens. Reading this reminded me of Rendezvous with Rama – it has the similar mix of hard science fiction as well the plot point of humans trying to figure out the motivations of an unknowable alien. It is a fitting conclusion to the series and a book that has stayed with me more than I expected it to.

SIDENOTE – There is one thing I never figured out about these books. Where are the White people? We have a future where all the conversation happens in Swahili, or Mandarin or Portugese – but no English. We have characters that are of different ethnicities, but no WASPS. Whats up with that?

Review: The Docker Book by James Turnbull

by

It is hard to avoid Docker. Hacker News has been abuzz with it for years, The Register ran an exhaustive feature about it a couple of months ago; indeed it seems to have taken over the DevOps world.

But why do I care? I am a developer, I live in the land of abstractions. The JVM is as low as I go my friends.

The problem is, all developers need to do releases.. And releases have a tendency to go very wrong..

Docker_Releases

So, I decided to educate myself. What is it about Docker that has got the cool kids on Hacker News all excited?

I took a look at some Youtube videos, tried out the tutorials and read a handful of blog posts and how-tos on Docker. I just couldn’t get my head around it! Finally I took the plunge and spent the last couple of weeks working through James Turnbull’s The Docker Book.

So, am I enlightened? The short answer is – yes, I have enjoyed working my way through the “Docker Book” and I have a much better idea on how to use Docker and the sort of use cases it is designed for.

The book is written in a tutorial format. We start with the basics about Docker and containers and move on to installing Docker on your favoured Linux(1) distribution.

Once we have Docker up and running, we learn about the basics of Docker. How containers can be created from images and how these images can layered. We learn about the Docker repository can be used to download standard images (for example, the image for ubuntu:14.04 can be used to build a base container that runs Ubuntu 14.04 LTS) and how to build containers from the images that we define. The author walks us through setting up and managing some simple containers.

All the Dockerfiles and any scripts and code used in the examples is readily available from the Github repository that the author has setup for the book(2).

I suspect most readers will get the most value out of chapters 6 and 7 of the book. Here the author goes through some examples including:

  • Using Docker to build a test environment
  • Building a continous integration pipeline using Jenkins and Docker
  • Building a web application that is deployed on multiple containers

These examples are quite detailed and well designed. Most of them could be used as a basis for a Docker based application stack “in the real world”.

Chapter 8 explores the eco-system(3) that is being build up around Docker focusing on service discovery with Consul and orchestration with Fig.

The book concludes with chapters on the Docker API and how Docker can be extended.

“The Docker Book” does not go into details on how containers work beyond the introductory chapters. The focus of the book is about learning what you can do with Docker and it succeeds admirably. I deducted half a star from the review simply because the author does not delve much into things like performance implications of using Docker or on how exactly the operating system may allocate resources to applications running in containers. There are plenty of resources online on these topics4.

You can’t go wrong with “The Docker Book” if you are looking for a hand-on introduction to Docker. James Turnbull is a good tutor and the resources accompanying the book are great.

Will Docker solve my release woes? Is it actually ready to be deployed in a corporate setting? Perhaps a topic for another post..

My Rating: 4.5 out of 5

Notes:

  1. Instructions for use of Docker on Windows and MacOSX are provided but are skeletal. Basically you need to use Boot2Docker
  2. I worked through almost every single example from the Kindle edition and didn’t find a buggy script or typo!
  3. The eco-system is moving fast. Kubernetes from Google is also worth checking out.
  4. The Docker blog is excellent

Review: The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win by Gene Kim et. al

by

The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business WinThe Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win by Gene Kim
My rating: 4 of 5 stars

The “Phoenix Project..” is a parable about technology, business and an introduction to the hot new buzzword of the day – “DevOps”. We follow Bill as he is promoted to be the head of IT Operations in the fictitious auto parts company “Parts Unlimited”. Bill is in for a rude shock as he leaves his comfortable middle management job behind and is thrust into the world of corporate politics, disastrous projects and a company rapidly falling behind it’s competitors and losing market share and money. The root of the problem appears to be a dysfunctional technology group and a complete breakdown in communication between the business and technology groups within the company.

The issues explored here will be familiar to anyone who has worked within technology in any sort of corporate setting. The challenges Bill faces – unclear requirements, unrealistic expectations and ever tightening budget constraints – are present everywhere. The book focuses on technology operations and we go on a journey with Bill as he tries to institute a change management procedure, keep control of production environments and tries to balance key staff who seem to spend most of their times fighting fires instead of delivering on projects.

The methods and technologies Bill and his team adapt should also be familiar to most IT folks. We have change management procedures (ITIL), Kanban boards, and continuous delivery methods. Gene Kim et. al do an excellent job of explaining how these methods work and go beyond the buzzwords in showing how these can be effectively used. The situation Bill inherits at Parts Unlimited may be extreme but its not too far off the mark.

I strongly recommend the Phoenix Project to anyone who works in technology in any domain. As a developer, I don’t have much insight or indeed interest in how IT operations work and the sort of challenges they face. This book forced me to think more about why we have change management procedures and how operating and maintaining an IT infrastructure is as (and probably more) challenging than building the applications that run on that infrastructure.

I have deducted a star simply because the writing can be clunky in parts and I feel the book would have benefited from more editing. The characters are caricatures of the type of personalities you find in most corporate settings. It can be a bit much at times (like the binder carrying manic depressive CISO), but it didn’t detract from an informative and engaging book

Review: Daemon by Daniel Suarez

by

Daemon (Daemon, #1)Daemon by Daniel Suarez
My rating: 3 of 5 stars

TLDR – Daemon starts off as a promising techno-thriller with a somewhat plausible premise but ends up being a run of the mill action roller coaster with killer robots. It’s a fun, if unsatisfying genre piece.

Daniel Suarez knows his domain – contemporary / near future technology and it’s implications. What I am also quite sure about that he has a rather pessimistic view of where things are going. Daemon starts as a crime procedural with a small town cop trying to solve two seemingly unconnected deaths that appear accidental. We quickly find out that there is a rather sinister force behind these deaths. We encounter disenchanted, anarchist-libertarian hackers, mysterious computer programmers who are not quite who they seem, and lots of sinister government types who simply know whats best for everyone.

The key character is the eponymous Daemon – a networked, non sentient computer system that is a dead computer genius’s gift to humanity. The Daemon has very specific plans (though they are never revealed – we will have to wait for the sequel) for humanity and it goes about recruiting brilliant, motivated followers through a variety of somewhat plausible means. We have entertaining descriptions of computer games and call centre software amongst other things. I really enjoyed this, the first half of the book. A particular standout was the police / FBI raid on the dead computer genius’s computerised mansion which I found most satisfyingly and gratuitously violent and explosively entertaining.

The book jumps forward a few months around the half way mark. This is where things get problematic. There are large passages that involve discussions between nameless “important” people in the FBI, CIA, NSA and other alphabet agencies as they wring their hands and try and figure out just exactly what is going on. Yes, we know government bureaucrats are clueless, thank you. The episodic, multi-character structure of the book also becomes a problem here. There are a number of characters who fade in and out. There is a particular character, a FBI special operations type fellow, who must be based on someone the author dislikes. He appears in two long passages, and appears to take a huge amount of punishment: being blown up, burnt, shot at, attacked by killer robots, being thrown off a car, etc. But it is difficult to really care too much because we don’t know anything at all about this particular, long suffering sap. The book builds up to an explosive climax involving a long car chase and,yes, more killer robots.

I enjoyed reading Daemon – just like I enjoy big budget sci-fi / action movies or playing first person shooters. There are some neat touches, cool technology, lots of explosions, and killer robots. But, in keeping with genre tropes, we also get gratuitous violence, paper thin characters, and an inconsistent plot. A strong recommendation for those who like computer games and are anarcho-techno-libertarians. An entertaining and somewhat lightweight read for the rest of us.

The WhatsApp acquisition

by

The water-cooler was abuzz this morning with news of Facebook’s $19 billion acquisition of WhatsApp, a tiny company. With the claimed 400 million users that WhatsApp brings to Facebook, the numbers involve value each user at $40. That is an astonishing amount of money for a service that is monetised through application sales, not via advertisement. There have been a number of articles and blog posts online analysing this deal. This is not one of them..

My colleagues are a quiet and taciturn lot. Office banter is limited to a “Good Morning” and a “See you later..” outside of the lunch hour. For the first time, in my admittedly short stint here, we had a bonafide conversation that was not even tangentially related to trading systems and market data feeds. We got talking about what it means to be a programmer working outside of the startup / silicon valley scene. One of my colleagues remarked that he spent half a decade in further education and a lot longer learning the ropes until he got to the point now where he is comfortable and financially secure. He wondered if that time would have been better spent writing a new chat or social network. Perhaps a new way of optimising the transmission and sharing of ribald jokes, or for improving the sexting workflow.

We carried on in a similar vein for a while when the most introverted of our lot spoke up. He said: “I was just never interested. The thought of building the next Facebook or Twitter just doesn’t excite me. It was never something that was on my radar.”

I spend way too much time on Hacker News. The Silicon Valley culture and eco-system fascinates me, but it does not inspire me. I marvel at the numbers that are thrown around. A few billion here, a few billion there, but I also wonder about the utility of it all. It is now fashionable to talk about how much of a talent drain banking has become. How so many people left promising careers in academia and engineering to cut code and make money on Wall Street and the City. In a few years I can see people talking in similar terms about Silicon Valley. “He was a promising scientist, but he joined Google to help them optimise the placement of adverts on search results.”

I find the earnest tone of discussions on Hacker News and of the job postings for these start ups deeply ironic. They talk about changing the world, wanting rockstars and working on cool new technologies. Yet, the end goal is a big payout via IPO or acquisition having built a better way of sharing food selfies. I think these headline acquisitions are a honey trap for programmers. Somebody, like my colleague, who wouldn’t really even think about working for a startup building a “trivial” app might realise that the App may be a gateway to that long dreamt of retirement on the beach.. You might get a lot more people ready to work for peanuts with the hope of striking it rich one day. Perhaps it is not a colossal waste of money after all..

Review: Moonwalking with Einstein by Joshua Foer

by

Moonwalking with Einstein: The Art and Science of Remembering EverythingMoonwalking with Einstein: The Art and Science of Remembering Everything by Joshua Foer
My rating: 4 of 5 stars

Joshua Foer’s Moonwalking with Einstein

The tag line on the book – “The art and science of remembering everything” is misleading. There is little in the way of prescriptive material here. The book is more of a travelogue and memoir of the years that the author spent and his journey from being a journalist covering a rather nerdy subculture to becoming the somewhat unlikely Memory champion of the USA.

We join Foer as he journeys to the world memory championships and meets a variety of entertaining, eccentric and quite bizarre characters. From the ultra suave and successful memory coach Tony Buzan who runs a global memory empire and wears clothes inspired by seventeenth century sword fighters to the cane wielding English eccentric Ed Cooke who formed a secret society of memory champions whose main purpose seems drinking beer.

This is not a scientific study or a self help book. Rather it is a study of characters and of the people who spend so much time and are completely committed to a rather arcane pursuit of somewhat dubious utility. The author also goes into some detail on the techniques used by champion memorisers such as using memory palaces and associating easily remembered and recalled images to all kinds of data that needs to be memorised. The emphasis here is again on entertainment rather than instructions as we are invited to imagine Claudia Schiffer taking a luxurious bath in a giant tub of cottage cheese on the sofa of the author’s childhood home. Apparently it is easier to remember titillating images than it is to remember chaste ones (who would have thought?).

The author also takes some interesting, if anecdotal diversions into topics such as chicken sexing and an exploration of savants capable of incredible feats of memory. Foer spends time with people who can’t remember their last thought as well as those such as Kim Peek, the savant on whom Dustin Hoffman’s Rain Man was based, who spends his days memorising the phone book. All of the characters are sympathetically portrayed, even those that the author is clearly ambiguous about.

The most enjoyable parts of the book are the ones where the author describes his journey towards becoming a “memory master”. The one image that I will take from this book is that of Joshua Foer sitting in the basement of his parent’s house in his underpants wearing giant industrial earmuffs and safety glasses spray painted black with tiny pinholes attempting to memorise long lists of random numbers.

Moonwalking with Einstein does come out like a mockumentary at times but it is clear that the author respects, even enjoys the company of, this strange brotherhood of unlikely athletes that he came across on his journey. I recommend this short and entertaining book to those who enjoy popular science books and as well as those who enjoy character studies and travelogues in the vein of Bill Bryson.

4 stars out of 5.

Review: Vishnu’s Crowded Temple by Maria Misra

by

Vishnu's Crowded Temple: India Since the Great RebellionVishnu’s Crowded Temple: India Since the Great Rebellion by Maria Misra
My rating: 4 of 5 stars

Vishnu’s Crowded Temple is an intriguing take on the history of modern India. As the title indicates, the book focuses on the politics of late British Raj in India and that of the independent Indian state after 1947. This is very much a political history. Ms. Misra offers much food for thought on the impact of caste, class and religion on political life in modern India.

The book is well written and the style is informal and anecdotal. The author tackles a topic that could be rather dull with panache and colour. The best sections of the book are those around the turn of the 20th century. We find befuddled victorian British administrators attempting to categorise and control the Indian electorate as well as a number of ambitious Indian politicians, including M.K. Gandhi, jostling for power and influence with nationhood and independence now a distinct possibility.

The book traces the dominant forces of modern Indian politics from the Hindu reform sects of the nineteenth century to the caste based “reservation politics” in the late twentieth. The period covered by the book encompasses rapid industrialisation, globalisation, two world wars and a tumultuous partition of the Indian subcontinent. The book focuses on political history at the expense of ignoring or skimming some important chapters in Indian history including the relationship with Pakistan and China, separatist movements in Kashmir and the north-eastern states and the impact of terrorism in more recent times. We also don’t get much insight into the everyday life of Indians with the focus on politics and economics.

This is not a good “first Indian history book”. If you are new to India, I would recommend “India: A History” by John Keay or the excellent “India after Gandhi” by Ramachandara Guha. With the great “Tamasha” that is the Indian elections coming up in 2014, Vishnu’s Crowded Temple is an excellent read for those who want to understand more about Indian politics and political attitudes.

Review: The Shadow of the Torturer by Gene Wolfe

by

The Shadow of the Torturer (The Book of the New Sun #1)The Shadow of the Torturer by Gene Wolfe
My rating: 3 of 5 stars

My rating : 3.5/5

“The Shadow of the Torturer” is a difficult book to read and to review. The New Sun series of books by Gene Wolfe are often described as the best fantasy ever written. I approached “The Shadow..” expecting to be blown away, but ended up a little baffled and quite intrigued.

The book is narrated by Severian, the titular Torturer. The book is structured as Severian’s memoir written some unspecified time in the future. Severian informs us at the start of his memoirs that he has an eidetic memory. His tale is structured as a series of vividly remembered vignettes that loosely follow Severian’s journey from his time as an apprentice Torturer in the Citadel to his banishment the beginnings of his travels.

You would expect somebody with total recall to be the most objective narrator possible. Yet, following Severian’s story often leaves us perplexed. To put it briefly, things happen to Severian. He behaves like a toy that is wound up and left to rattle across the city of Nessus. He meets characters, gets into and out of difficult situations in strange places, yet emerges unscathed without much comment or reflection. This is not because of poor writing, but at this early stage in the series seems like a clear plot device. I suppose this is the beauty of the book. You know something is up, but it is not clear exactly what and why.

The descriptions of a (post apocalyptic?) Earth are very well done. The city of Nessus, where all the action takes place, is intriguing. It is somewhere in the Southern Hemisphere, and its people live in a monarchial, class based, almost medieval society with some hints of far future technology. Think medieval swordsmen riding genetically modified uber-horses. The story is set in the far future, and the author often throws in passages that convey a sense of decay and melancholy. There are no “information dumps”, and the history of this society is not something that we know about. The “Urth” is as it is, and forms an intriguing background to Severian’s journey.

Since this is the first in a series of books, I will not comment much on the characters. We meet many, but we don’t get to know any of them, since they are all described to us by Severian. He may have total recall, but as the story progresses, he is quite possibly a lousy judge of character. You may find this endearing or irritating. At this stage, I am willing to give the author some leeway.

Review: Existence by David Brin

by

ExistenceExistence by David Brin
My rating: 3 of 5 stars

(2 and a half stars out of five)

Existence is the first book by David Brin that I have read. It is a curious blend of a novel of first contact, a tour through a near future earth, conspiracy theory and an almost seven hundred page primer on the Fermi Paradox. I came to the book with an open mind in light of the mixed reviews on Goodreads and other places. There were times while reading Existence where I felt very close to giving up. I slogged through, but it was a close run thing.

This is an idea driven as opposed to character or plot driven work of fiction. We are introduced to a number of characters, but as the book progresses, it becomes very difficult to keep track, or indeed to care much about most of the characters. In the very first chapter, we are introduced to a space “garbage collector” astronaut and his pet / helper cappuchin monkey. The astronaut character, Gerald Livingstone, stays with us till the very end, but he never really progresses much from being a simple plot device in the beginning of the book to ending up being an obvious mouth piece for the author by the end. Characters come and go, some pop up again towards the end of the book for no particular reason. Some turn up and dump huge amounts of information, and then go away. Some do so in extremely aggravating manners (including a “rastafarian” space scientist who has “aromatic smoke” coming out of his dreadlocks – really?).

So, if you are looking for plot driven science fiction, stay well away. If you are looking for characters that you can relate to, or who have a sense of humour, or who you may care about just a smidgen – this book is not for you. If, however, you love hard science fiction and have spent any time at all trying to figure out “Are we really alone out here?”, you are in for a treat.

The book starts with our space garbage collecting astronaut hero and his pet monkey picking out an alient artifact from Earth orbit. The first half of the book deals with the fallout. The book alternates between plot driven, character POV chapters, and, for want of a better description, information dumps – wrapped as excerpts from real and future fiction. Some of these chapters do feature our aromatic smoke spewing “rastafarian” as a talking head. With the author we get to explore various theories on the Fermi paradox (why has no-one said “hello” yet?), as well as the traps and pitfalls that may face an civilisation like ours as it reaches for the stars. Some of these segments are enlightening, some are entertaining and a few are rather dull.

Existence also gives us tentalising glimpes of near future with climate change, societal strife, and interesting political issues. To the book’s detriment, most end up being undeveloped plot dead ends. We also get to meet a number of aliens, but most are disappointingly human, yet quite devoid of humour. There is an entire subplot involving super-intelligent Dolphins which also peters out. We have re-incarnated Neanderthals, AI “citizens”, smart-mobs, and a number of other plot points that come and go without really moving the plot forward or adding anything to the overall narrative of the book.

Mr. Brin is clearly a man of ideas, his book positively overflows with them! I just wish he had sacrificed a few of these ideas and focused more on a coherent plot. This is an engaging read for those who enjoy hard science fiction and books on first contact.

Review: Snow Crash by Neal Stephenson

by

Snow CrashSnow Crash by Neal Stephenson
My rating: 4 of 5 stars

4 Stars

Snow Crash is the book that made Neal Stephenson a sci-fi superstar. I have read and enjoyed most of Neal Stephenson’s work and was looking forward to reading what is widely acknowledged as a Science Fiction classic.

You are transplanted to the not so far future, riding shotgun beside Hiro Protagonist – master hacker, concert promoter, freelance spy, and the greatest sword fighter in the world; currently employed as a pizza delivery driver. He is joined in the first chapter by Ms. YT (Yours Truly) – the precocious 15 year old skateboarder, escape artist and all around badass. We also find Raven, a giant Aleutian, with a vendetta against the United States, and a tactical nuclear device in the sidecar of his Harley Davidson. When a man has “Poor Impulse Control” tattooed across his forehead, you know that his appearance is not going to be good news.

In Snow Crash, the government has shrunk and the US is split into a number of corporation controlled “burbclaves”. Policing, infrastructure, intelligence gathering, and even religion have been outsourced to competing corporations. The world is lit by the ambient glow of advertising billboards, some of them advertising the Mafia’s guaranteed thirty minute pizza delivery. Yes, the Mafia is in the pizza delivery business (and is Hiro’s employer), and is run just like a corporation, with three ring binders filled with detailed descriptions on how each franchise should be run.

The dystopian near future USA is still a magnet for refugees from the third world. We find a huge flotilla called the Raft moving across the Pacific ocean and ready to disgorge hundreds of thousands of refugees onto the West coast. Against this backdrop, we find dead hackers and a mysterious virus that can jump from computer to human. After losing a friend, Hiro tries to get to the bottom of the mystery and with YT’s help, uncovers a nefarious plot by a powerful billionaire to take control of society. Hiro and YT encounter hackers speaking in tongues, Vietnam veterans with cybernetic enhancements, and adorable cyborg dogs.

Mr. Stephenson, however, also spends an inordinate amount of time talking about Sumerian and Hebrew myths, and trying to convince us that all of this has happened before. We get chapters which read like excerpts from an Encyclopedia or quoted verbatim from an academic paper. We know that Mr. Stephenson can write snappy, kinetic prose. So it is jarring to move from high speed skateboard chase sequences and fantastic sword fights to ten pages of description of the Sumerian political system and language. It is interesting, but feels out of place given the otherwise dynamic nature of the book.

Despite its flaws Snow Crash is a wonderful work of speculative fiction, and fully deserves its “Classic” status. It is engaging and thought provoking. The central premise of the book is that ideas are viruses and can be communicated. This is a clear allusion to advertising and how ubiquitous it is and the power it exerts. In a world that is dominated by corporations and capitalism, the corporation that has the most number of clients (voluntary or otherwise) is the most powerful. This is powerful stuff.

Like the best satire, it is a scathing critique of where our society was headed. I recommend it whole heartedly to any science fiction fan. It has all the meaty science, action and friendly cybernetic canines you could wish for.
