I said to myself "I'll just read a few passages of the book, just to relax a little, as I have a lot to do". Yeah right! I've started reading and I didn't stop until it was done. Stonewielder is a classic Malazan Empire book, but also bearing Esslemont's personal touch. There is the catastrophic magic battling immense godly power, while the ordinary soldier (the book focuses on heavies) carries on lead by the tragic commander, there are the weird twists from a perspective to another, the switches from a storyline to another, typical of a Malazan book, but also a bit less epicness and a lot more human failing, more characteristic to Esslemont than to Steven Erikson.

I have to say that I find the title to be a little off. The part of Greymane is quite insignificant until close to the end. A great book, nevertheless, and a nice prelude to The Crippled God, the tenth book (and laaast! :( ) in Steven Erikson's Malazan Book of the Fallen series, that I intend to read as soon as possible.

MCTS Self-Paced Training Kit (Exam 70-511): Windows Application Development with Microsoft .NET Framework 4 is a terrible book. It tries to cover the entire subject of Windows application development, so that means it must explain both Windows Forms and Windows Presentation Foundation concepts. Not only that, but it must do it in a consistent, comprehensible way, avoiding confusion between similar ideas that often overlap. It fails miserably on all counts, probably because it can't be done in a single book, but also because it is a jumbled mess that no one that is unfamiliar with the concepts there can actually learn from. I wonder, was poor Matthew Stoecker presented with the questions in the exam and asked to write a book to cover them? Because that would explain a lot. The 70-511 test itself it not much smarter.

The book starts with Chapter 1: Building a User Interface, in which it presents some basic WPF concepts like controls, resources, styles and triggers. If well written, this could have been a good start. It then continues with Chapter 2: Working with Events and Commands, containing stuff about events and commands, obviously, but then animations! So a novice at desktop applications now has to suddenly contend with animation. Maybe it was a slip up, so let's try Chapter 3: Adding and Managing Content, talking about brushes and the visual tree, even transformations, but then it goes into using MediaElement and MediaPlayer to play sounds and video.

Chapter 4: Windows Forms and Windows Forms Controls starts talking about Windows Forms, but in a completely new way and structure than the WPF part. It talks about modifying properties in Visual Studio, it describes the controls, one by one, with properties and all. It's like a completely new book. Chapter 5: Working with User-Defined Controls starts with Windows Forms, then it tries to explain Control Templates in WPF, then jumps back to user controls, this time in WPF.

The book switches to data in Chapter 6: Working with Data Binding, explaining the WPF Binding mechanisms including validation, and in Chapter 7: Configuring Data Binding it talks about various data sources and DataTemplates, also for WPF. Then it moves back to Windows Forms, Chapter 8: Working with Data Grids and Validating User Input, which starts talking about data bound controls in Windows Forms, but then it goes on and on about the DataGridView. It goes on by combining in a single subchapter Windows Forms validation and IDataErrorInfo in WPF.

Before you know it, in this whole confusing bunch of thrown facts, with no structure or plan, you go through Asynchronous Processing (using BackgroundWorker and delegates, but not Tasks!), Globalization and Localization (yeah, that is the important part) and integrating Windows Forms and WPF together, all in Chapter 9: Enhancing Usability. Chapter 10: Advanced Topics manages to mix together security, application settings and Drag and Drop. Chapter 11: Testing and Debugging WPF Applications was, I think, the most decent chapter, but still kind of frankesteined together from different sources, while Chapter 12: Deployment, talked a bit about Windows Installer and ClickOnce.

Conclusion: messed up as a whole, messed up in each small part, it's a fractally messed up book! You even get "chapter summary" points that were not covered in the actual chapter. I couldn't wait for the book to end, but I've managed to read it all. On Monday I am taking a test on this, for the 70-511 exam and I am really not sure how it's going to work out. Luckily for me I knew most of the concepts covered in the book from personal experience so we'll see how it goes.

The book (MCTS Self-Paced Training Kit (Exam 70-503): Microsoft® .NET Framework 3.0—Windows Communication Foundation) covers just about everything there was in the .Net 3.0 version of WCF. As I was saying in a previous post, in order to "upgrade" to a 4.0 version you need to read about the router services, service discovery and simplified configuration.

What I liked about the book is that it is a no bullshit, yet comprehensive reference to the tasks for which one would use Windows Communication Foundation. I found it easy to read and comprehend and, most of all, easy to remember.

The Shigurui (Death Frenzy) manga is now complete. The beautifully terrible story of two exceptional samurai in a world of politics, betrayal and cultural conditioning, locked in absolute rivalry, has ended with the 84th chapter, Pure Crimson. There is an anime with the same subject, I've also seen it and it is really great, even if it stops dead after 11 episodes. I actually recommend to watch the anime and then continue with the chapters in the manga, in order to understand better the feeling of the story. It must be said that the translation from a book written by a war veteran to a graphic novel by a mangaka 58 years his young and then translated to TV anime has not lost, but gained insight and emotion.

One can read the entire manga at MangaFox.

The fifth book in the Dexter Morgan series by Jeff Lindsay, Dexter is Delicious is slightly better written than the first four, but also less credible. The main character is torn between his Dark Passanger and the desire to love and protect his newly born child. He thus decides to "become human" in the worst possible moment. His brother Brian, who attempted to kill Dexter's adoption sister Deborah, also makes an appearance. The bad guys in the story are a cannibal ring and they are quite the gourmet, requiring Dexter as a main course.

The problem with this book, apart from the general Dexter Morgan hard to swallow leaps of faith, is that the Dark Passenger is pushed back, as Dexter gets in tough with his parental instincts. For me, at least, Dark-Dexter was the main character and the mischievous whispers of his inner demon were the delight of the series. If I would want to know people having kids and loving their pinkness I would read something else entirely.

I will continue to follow the series, but I can't help feeling a little dissappointed every time I read one of the books in the series. With such a wonderful subject, the possibilities are limitless and a great deal of potential wasted.

Programming Collective Intelligence is easy to read, small but concise, and its only major flaw is the title; and that is because it is misleading. The book touches quite heavily on using collective information and social site APIs, but what it is really about is data mining. It may not be a flaw with the majority of readers, but personally I wouldn't care about the collective, the Facebook API or anything like that, but I was really interested in the different ways to analyse data. In that sense, this book can be taken as a reference guide on data mining.

Each algorithm and idea is accompanied by Python sources. I personally dislike Python as a language, but the author afirms he chose it intentionally because the algorithms look clear and the source is small, with its purpose unhindred by many language artefacts. The book was so interesting, though, that I plan (if I ever find the time :( ) to take all the examples and do them in C#, then place them on Github.

The book covers classification and feature extraction, supervised and unsupervised algorithms, filtering and discovery and it also has exercises at the end of each chapter. Here is a short list:

• Making Recommendations - about the way one can use data from user preferences in order to create recommendations. Distance metrics and finding similar items to the ones we like or people with similar tastes.
• Discovering Groups - about classifying data into different groups. Supervised and unsupervised methods are described, hierarchical clustering, dendograms, column clustering, K-Means clustering and diferent methods of visualisation.
• Searching and Ranking - it basically explains step by step how to make a search engine. Word frequency, word distance, location of a document, counting methods, artifical neural networks, the Google PageRank algorithm, extraction of information from link text, and learning from user clicks can be found in this chapter.
• Optimization - simulated annealing, hill climbing, genetic algorithms are described and exampled here. The chapter talks about optimizing problems like travel schedules and the example uses data from Kayak.
• Document Filtering - a chapter about filtering documents based on preferences or getting rid of spam. You can find here Bayesian filtering and the Fisher method.
• Decision Trees - a very interesting method of splitting information items into groups that have a hierarchical connection between them. The examples use the Zillow API
• Bulding Price Models - k-Nearest neighbours, weighted neighbours, scaling.
• Advanced Classification - Kernel Methods and Support Vector Machines. This is a great chapter and it show some pretty cool uses of data mining using the Facebook API
• Finding Independent Features - reviews Bayesian classification and clustering, then proposes Non-Negative Matrix Factorisation, a method invented circa the late 90s, a powerful algorithm which uses matrix algebra to find features in a data set
• Evolving Intelligence - bingo! Genetic Programming made easy. Really cool.
• Algorithm Summary, Third Party Libraries and Mathematical Formulas - if you had any doubts you can use this book as a data mining reference book, the last three chapters eliminate them. An even more concise summary of the methods explained in the book, listing every math formula and obscure library used in the book

Conclusion: I really loved the book and I can hardly wait to take it apart with a computer in hand.

This book is different from the books I usually read because it is an autobiography. However it has enough science in it to be great, enough fantasy in it to be totally inspirational and also it is one of the most real (and thus sad) books I have ever read. What is even nicer is that the book is free online on Anthony Zuppero's site. I can't recommend it enough. Go there, download it, read it: To Inhabit the Solar System

The plot itself is about this physicist guy, diagnosed with Asperger's syndrome, who gets into his head that we could build rockets to go to other star systems. It all starts in 1968, when he reads about the Dyson nuclear bomb propulsion, an outrageous scheme to detonate nuclear bombs to push a rocket. From then on, he embarks into jobs that are closer and closer to this purpose, always finding solutions to problems that appear along the way. In the end, he finds a way to cheaply get the water from comets, asteorids, moons and use it to propel spaceships around the Solar System. He practically gives us the keys to the universe, the highways that would allow the thorough exploration and utilization of resources in our solar system. It is just amazing.

There are multiple things that I liked about the book. Most of all, I liked the guy. He is what I would call a true hero: he finds a cause and dedicates his life to it, without any desire for personal gain. He doesn't just blab around about the ideas that he has, he finds people, resources, makes calculations and determines the problems that arise and specific concrete solutions for them. Then the style of the book: so bloody honest, so many things to be learned from the way he repeats what is important, the details of all his thoughts, hopes and desires; a great read. And last, but not least, the technical aspects of the book. After reading it, you will be able to understand each step of getting fuel and construction material from space, using it to propel and build stuff, all in a reasonable enough price and without the need for expensive planet-space trips.

Now, there are some issues with the book. First of all, it is not at all polished. It says its story, but it's also filled with personal notes, incomplete chapters and
various information. My guess is that at some time he wanted to publish the book and no one was interested. Or maybe he just didn't want to waste time polishing the book and stop people from getting the ideas in it. Or maybe he just didn't feel the story ended. Either way, for me it added to the charm and realism of the book, rather than take stuff away.

It was heartbreaking to read about the death of Gene Shoemaker. In the book - the author took it hard - but it so happened I was reading the book while they announced the death of Brian Marsden, another proeminent character in the book, and I felt the pain anew.

Bottom line: you should read this. If not for the quality of the book, not for the realistic description of government agency inner workings and personal tricks to get something done, if not for the amazing person that Anthony Zuppero is, read it for the detailed description on how we could today (actually, from about the 1980's) inexpensively inhabit the Solar System.

The Void Trilogy ends with The Evolutionary Void in a typical Hamiltonian way: completely off the scale science and fights, actions with galactic and universal implications and the bunch of special heroic people that lead the entire story to a climactic finish.

I couldn't wait for the last book of the trilogy to get out and I finally got hold of it, but more than a year had passed since reading the first two. Most of the characters I had to remember while reading the book, something that degraded a bit the reading experience. Take it as a hint: before starting a Peter F. Hamilton series of books, make sure they are all available before you start, as you can't let them out of your hands until you get to the end and the feeling of loss is horrible.

Now, about the book itself. The middle of the galaxy hosts an all devouring and unstoppable Void, inside which thought is the main law of physics and which feeds on the mass of the worlds outside in order to sustain itself. Basically, the heroes in the book are battling galactic cancer. The style of the narrative mixes incredibly advanced technology with an archetypal feudal heroic fantasy, bringing them flawlessly together at the end. Not everything makes sense, but then again, not everything could. Simple solutions to problems were available, but never explored, and some characters were popping in and out of the book stream like so many quantum fluctuations. But on the whole, it was a great reading, keeping me connected for the entire length and, unexpectedly judging by the Hamilton books I have read, with a good, satisfying ending.

Now, I plan on reading some non fiction books, then I will probably return to the Prince of Nothing universe. After that, who knows?

I almost expected the guy to be Canadian. :) This series of fantasy books is a masterpiece of writing. Not only it is complex of plot and emotion, but the characters are many, diverse and (most of all) different.

So far, the A Song of Ice and Fire saga, written by American author George R. R. Martin, consists of four books, the first published in 1996 and the last in 2005. At least three other books are planned in this series. The plot is a historical fantasy, but one unlike the books I've read recently. The aspects of magic and otherworldiness are rare, the bulk of the writing being about the feudal world, with kings, knights, low borns, maidens and whores, thieves, rapists and murderers, plotters and honorable men. No wonder that, lacking a lot of special effects, the story has been selected as the basis for a TV series.

But what is more important than anything is that the writing is really good. The characters are all human, with needs, desires, qualities and faults. You can't help but empathise with them, only to suffer at the cruel fate the writer bestows upon them. Not one escapes unscathed from the malice and pettiness of other people or from shere bad luck. You get to like the characters, then Martin fucks them up. I really wanted to use a more elevated language here, but it's the truth: the world he depicts seems horribly real, not a fairy tale of valiant white knights and pure maidens, but of ridiculous people grabbing lustfully whatever life offers them as it is unlikely their fortune is going to last long.

For the bad part, though, I think the author went too deep, got himself responsible for a lot of characters that he must now move forward, in gruesome detail. The fourth book became so large that he had to split it. He did so by character and geography, rather than by time, so a lot of the characters were missing from the fourth book, A Feast for Crows, and left for the fifth, but acting in the same timeline. At the end of A Feast for Crows the author explains his decision to not just split the book in the middle with a "To Be Continued" ending, and hopes for a publication of the second half in a year. That was in 2005. Ahem.

A lot of people are a bit confused by the long wait for the fifth book. Martin keeps making promises that he doesn't keep and, in July this year, he announced that A Dance with Dragons is already 1400 pages long and 5 chapters close to completion. I hope he does finish it quickly enough, although that would only prolong my suffering anyway. I am sure the fifth book will be as brilliant as the others, but then I will have to wait another 5 years for the sixth. I know TV series usually have no plot, but at least they come weekly ;)

Bottom line: The books are great, I recommend them to any lover of fantasy or even historical novels. I can hardly wait for the TV series, A Game of Thrones, as well.

While waiting for the tenth book in the Malazan Book of the Fallen saga, I went and read Prince of Nothing, by another Canadian author, R. Scott Bakker. This is a three book story, first published in 2004, about what I can only describe as a psychopath, member of a rationalizing sect, going out into the world to protect the secret of said sect.

The book is well written, although not nearly as brilliant as the Malazan series. However the subject of it is very interesting, at least from my standpoint. It concerns a human that is trained in the ways of mental manipulation, rationale and causality, something akin to the Vulcans from StarTrek, but with a very human side to it, the one that pushes one to amass power and use their knowledge to manipulate.

No wonder that the "prince of nothing" is the central character in the books, but not the main character, the role being left to a sorcerer, a man that is at the same time keeper of arcane knowledge and the scorn of ordinary humans. I can't help but empathize with the guy: basically a geek in love with a whore, while a psychopath destroys his world with insidious manipulation. ;)

There is another central character to the story, an insane barbarian, like a tortured Conan, who is both terrifyingly strong and ridiculously fragile, both a mindless warrior and a brilliant strategist. He is also, like Achamian the sorcerer, an exponent of humanity.

Prince of Nothing is a very smart book, one that can only get better as the writing skills of Scott Bakker improve. Its assets are both a scientific approach to the human psyche and a veritable intrigue of arcane powers in conflict with each other on the background of huge masses of clueless people. The plot itself is similar to the story in the Berserk manga, at least its start, where the strong warrior chooses to follow the charismatic and ambitious leader only to his doom. The moral, as I saw it, is that while we choose to live our lives with eyes closed, we cannot in good conscience pretend to deserve control over what happens to us.

I hope the series, known as "The Second Apocalypse", continues, since Prince of Nothing raised more questions than gave answers and the plot really caught my attention. A nice book that I warmly recommend.

You know when you are playing some famous game you get millions of pages discussing strategies and solutions to in-game problems? Well, if you think about it, all those pages could be brought together and bound in something like a book. Why not write StarCraft for Dummies or Professional Warhammer 40000? And with that in mind, how would you feel about a book whose entire purpose is discussing Pac-Man?

Curious yet? You can check it out here! It writes about the algorithms used in the game, the tips and tricks for playing, even the different personalities of the four killer ghosts! Everything complete with pictures, diagrams and YouTube videos!

If there was any doubt about the style of writing and book structure for the first novel from Ian Cameron Esslemont in the Malazan universe, the second book: The Return of the Crimson Guard, dispelled any. One can barely see a little more focus on action than on description compared to Steven Erikson, but, having read it, I feel like this is the tenth novel in the series, not the second in a parallel Malazan world.

First of all, it is a full length book, similar in size with the ones written by Erkison. Again we see an amassing of forces, set to converge towards the climactic end. There are the Avowed of the Crimson Guard with a full army of mercenaries in tow, there is Lasseen, empress of the Malazans, there are Seguleh, man-beasts, D'ivers, Soletaken, mages of huge power, Claws, Talons, Seti, Wickans and the all pervading regular Malazan soldier, with focus on our favourite sort: the sapper :)

I have to say that the writing is so similar to Erikson's, that it even acquired the same problems. There is a lack of finality to just about anything. One just knows that a lot of questions will remain ... not unanswered, but simply ignored... and that the next books will bring more wonder, more magic, more characters, all dancing around this huge singleton of a main character which is the universe of the Malazan Empire. It's refreshing, it's great... it's annoying!! :)

Having said that, this was another great book, one of those writings that make me want to abandon programming to start writing, even if I know nothing about it, one of those books that make me want to abandon watching movies altogether, for lack of detail and significance. Now my big dillema is what should I read next...

Forced to wait for the tenth and final novel of the Malazan Book of the Fallen series, due to be published this year, I've started to read the books placed in the same universe written by Steven Erikson's friend, Ian Cameron Esslemont. The first of these books is Night of Knives, which is rather short compared with Erikson's novels or, indeed, with the second Esslemont book, Return of the Crimson Guard, which I am reading now.

The book is alert, as it spans a single night on the island of Malaz, during a rare event which weakens the borders between realms. Anything can happen during this night and, indeed, does happen. The island is assaulted by alien ice magic water dwellers, the dead house is under siege and Kellanved and Dancer are making their move towards the throne of Shadow realm. Meanwhile Surly is Clawing her way into the throne, a natural talented girl with too much attitude is trying to get a job and start an adventure and an old retired soldier gives his all once again.

All and all, it was a nice book. The writing style is clearly different from Erikson's, with less descriptive passages, a little more action and a more positive bias, tending to lend people more good qualities and having them end a little better. However, it only takes a few pages to get into the Malazan feel of things and enjoy the book.

The word that I think best describes the book is "naive". That's not necessarily a bad thing; people have been hooked by naive stories since forever. Isaac Asimov had some very simplistic plots where everything was going well for the main character. The Harry Potter series was also what I could call naive; didn't hurt it much. From the same perspective I can say that The Vorkosigan Saga, which now spans about twenty novels and short stories, had its share of success (and three Hugo awards) no matter what the writing style. That writing style should have evolved anyhow as each book was written.

Back to The Warrior's Apprentice, though. It's about a kid, son of royalty on his home backward planet, who singlehandedly buys a spaceship, runs a blockade, creates a mercenary force, fools everybody that he is older, is smarter than anyone and also foils a ploy to destroy his father. And the drama is, as teenagers go, that he doesn't get the girl. Now see why I call it naive?

However, I am sure I would have gobbled the whole series up when I was fifteen, so, even if I have decided to not read the other books in the series, it depends on what your tastes are. The Warrior's Apprentice is an easy to read, easy to follow, shortish book. As a travel book I guess it would be decent.

I've finally finished the book WPF in Action with Visual Studio 2008 by Arlen Feldman and Maxx Daymon. Simply put, it was a great book. Most of the programming books focus too much on structure, resulting in very comprehensive information, but giving one little in the way of actual work. WPF in Action is describing features while using them in a few applications that are built almost entirely out of code printed in the book. I think this is the second book any beginner in WPF should read, the first being one of those boring comprehensive ones :)

The book goes from a brief history of Windows Forms and WPF to Hello World in part one, then to describing layouts, styles, triggers, events and animations in the second part. The third goes to create a wiki application using commands and binding, datatemplates, converters, triggers, validation, then custom controls and drawing (including 3D!). I am a big fan of the MVVM pattern, but I liked that in this book, while it got described, it didn't suffocate the other topics, getting only a small subchapter in the binding section. The fourth part explains navigation, XBAP, goes briefly through ClickOnce and Silverlight, then has a large chapter about printing (too large, I believe). The book finishes with transition effects, interoperability with Windows Forms and threading.

All in all I think it was a very nice read. The authors clearly have a lot of experience and are quite qualified to talk not only about the features in WPF, but also the gotchas and some of the problematic implementations or even bugs. The fourth part of the book was a bit of a bore, though. After a pretty heavy 3D drawing ending of part three, I get to read a whole lot about really boring stuff like printing. I am sure that when need arises, though, this is the first book I will open to see what they did.

Bottom line: First three chapters are a must read. Maybe skip the 3D drawing part the the end of part three. The fourth is optional. The authors themselves said that they intended to write something that could be used as a reference, and I think they succeeded. So read the table of contents and see which parts of WPF you are really interested in in those optional parts.

The WPF in Action with Visual Studio 2008 link goes to the publishers site, where you can download the source code and even read some sample chapters.
