Good introduction
By Dan Nuttle
Good, quick introduction to Elasticsearch. Very useful if you're a Solr user already. If you're new to Lucene-based indexing and searching, there will be topics like analysis that will probably be pretty confusing. The book is fairly broad in scope, and although necessarily not very deep, it goes deep enough for a tutorial. It is a quick and effective way to learn enough to be ready to move on to more advanced resources. One note, this book makes no mention at all of Java APIs or APIs for any other language. Also, some things are already dated. The installation method for the web-based tool has changed a bit, and at least one example in the book doesn't work with the latest version of Elasticsearch (I used 2.2).

Definitely worth the fairly low purchase price so long as you don't expect it to be a comprehensive reference manual.

Great book to get started with Elasticsearch.
By MANOJ
This is a fantastic book to get started with Elasticsearch. The concepts are clear and concise. Joel explain everything in crystal clear detail and it is a joy to read. It also has relevant screenshots to help you understand things better.

Look no further. Go for it if you are an absolute beginner and want to learn the basics of Elasticsearch.

Introduction to Partial Differential Equations with MATLAB (Applied and Numerical Harmonic Analysis), by Jeffery M. Cooper

Overview The subject of partial differential equations has an unchanging core of material but is constantly expanding and evolving. The core consists of solution methods, mainly separation of variables, for boundary value problems with constant coeffi­ cients in geometrically simple domains. Too often an introductory course focuses exclusively on these core problems and techniques and leaves the student with the impression that there is no more to the subject. Questions of existence, uniqueness, and well-posedness are ignored. In particular there is a lack of connection between the analytical side of the subject and the numerical side. Furthermore nonlinear problems are omitted because they are too hard to deal with analytically. Now, however, the availability of convenient, powerful computational software has made it possible to enlarge the scope of the introductory course. My goal in this text is to give the student a broader picture of the subject. In addition to the basic core subjects, I have included material on nonlinear problems and brief discussions of numerical methods. I feel that it is important for the student to see nonlinear problems and numerical methods at the beginning of the course, and not at the end when we run usually run out of time. Furthermore, numerical methods should be introduced for each equation as it is studied, not lumped together in a final chapter.

Review

"Cooper's book stands out among a host of PDE works. It not only adequately treats traditional core partial differential equation methods but also integrates analytic solutions with numerical schemes through the implementation of MATLAB routines. As an application-oriented book that provides the basic definitions, theorems, and analyses of the solutions, it contains the core topics needed for a sound background in partial differential equations.... One of the book's excellent features is the availability of illustrative and challenging problems, some of which have been cast in the form of MATLAB projects. Such features undoubtedly make this a suitable work for a laboratory component of an introductory PDEs course. Recommended. Undergraduates through faculty."   ―Choice

This book is hit or miss
By MrDNA
This book does some things very well and some things not so well, depending on your perspective. Perhaps one of its problems is that it attempts to straddle the line between being a book for scientists and being a book for math students.

That said, it could stand a fairly hefty reorganization. For example, the relationship between Green's functions, weak solutions, and fundamental solutions could be brought together in an early chapter instead of spread throughout the book. Same goes for material on eigenfunction expansion.
The material on a given PDE for one dimension should probably be at least near the chapter on the same PDE in multiple dimensions, rather than being separated by 6-7 chapters.

On top of this, the material is sometimes hard to follow in terms of motivation and justification. This is not uniform, however, and some parts of the book are quite clear. And, all things considered, it does a fairly good job of presenting things rigorously without alienating its potential audience of scientists and engineers who are not as versed in proof-based books.

Aesthetically, there are a lot of somewhat serious typos and the typography is atrocious. For example, parentheses are not sized properly, bars written over letters do not cover the letters as they should. These are basic and easy to fix LaTeX errors, and it gives the book an appearance of having been rushed or at least not given the attention to detail it should have been.

Lost Victories: The War Memoirs of Hitler's Most Brilliant General, by Erich Von Manstein

Originally published in Germany in 1955, and in England and the United States in 1958, this classic memoir of WWII by a man who was an acknowledged military genius and probably Germany's top WWII general, is now made available again. Field Marshal Erich von Manstein described his book as a personal narrative of a soldier, discussing only those matters that had direct bearing on events in the military field. The essential thing, as he wrote, is to "know how the main personalities thought and reacted to events." This is what he tells us in this book.His account is detailed, yet dispassionate and objective. "Nothing is certain in war, when all is said and done," But in Manstein's record, at least, we can see clearly what forces were in action. In retrospect, perhaps his book takes on an even greater significance.

Review
WWII History, December 2005“Manstein’s Lost Victories is definitely one of the more interesting and informative German autobiographies to emerge from World War II. New publisher Zenith Press is to be commended for republishing it.”

Wall Street Journal, October 7, 2006"Generals don't make the best memoirists, mainly because they embellish while writing for posterity; the higher the rank, the worse the tome. The exception is the breathtaking autobiography of Field Marshal Erich von Manstein, the brilliant author of many Germany victories against the Soviets in World War II. Dismissive of oft-cited ‘turning points,’ such as the German defeat at Stalingrad, von Manstein contends that the war was never winnable for Germany because of the leader prosecuting it. As for Hitler's once much-vaunted kinship with regular soldiers, he says the Fuehrer had ‘as little in common with the thoughts and emotions of soldiers as had his party with the Prussian virtues which it was so fond of invoking.’ Coming from Hitler's greatest general, it's a most effective filleting.”

After realizing how important von Manstein was, his memoires showed how it was done
By Dennis A. Rose
It took me fifty years to understand who Erich von Manstein was, an orphan adopted into a family with a Prussian military tradition and with his new grandfather who had successful commanded an army, von Manstein desired to follow in those footsteps. As his mastery of strategic thinking grew, in 1940 he as chief of staff in one German army planned, pushed for and eventually won Hitler's approval over the heads of German military headquarters of his plan that won France in six weeks. From there he rose to command groups of armies on the eastern front as Field-Marshall von Manstein. His memoires describe in detail the strategic and tactical considerations, blows and counterblows which included victories and retreats until his relief in April of 1944. Even though the days of huge land battles are long gone, von Manstein's memoires teach us how huge strategic situations can be thought about and handled. He never was a Nazi, just a German soldier dedicated to his country who gave his best and lost his son in efforts for his country and fellow soldiers.

By Coach
I have always been curious about how WWII looked form the side of the German military. Manstein's book opened my eyes to the destructive role Hitler played over the German military by interfering in the conduct of the war at the operational level. It also addressed the question of blind obedience the German Generals gave to Hitler. Unfortunately, it did not address the role of the paramilitary units that followed the army into conquered territories inflicting genocide on people. The book explains the idea of mobile war developed by the German General Staff after WWI and its implementation during WWII. One of the most revealing facts was that Hitler did not have an understanding of the doctrine and refused to allow the army to conduct strategic retreats to gain a military advantage by its mobility. This ultimately caused the collapse of the German army in the east through attrition. You have to have a basic understanding of Easter European geography to appreciate the details of each campaign.

Valuable When Read in Context
By Niccolo Donzella
An incisive, well-written view of important WWII battles from the front row, this book is importantly balanced and enhanced by the accompanying commentary providing needed context about the author and his point of view. Manstein's role in forming post-war judgments on the Wehrmacht was significant, and the commentary helps place this book in its historical context. I found that the unit-by-unit battlefield detail could be wearying, as it was difficult to follow and Kindle does not do maps particularly well. Some of this was aimed, no doubt, at acknowledging the efforts of comrades in arms. The larger assessments were far more interesting to me, including those of Hitler as a military commander/strategist and the Wehrmacht's command, war and political issues. There is an unmistakable defensiveness to the narrative, certainly influenced by post-war and post-hoc concerns. Some of this seems to stem from Prussian military pride and tradition, offended by Hitler's direct involvement in military decisions and operations. But there is also a great silence about the the political units operating within his jurisdiction. Both the Wehrmacht and the Red Army fielded political authorities tasked with carrying out ideological warefare. These units on both sides were responsible for an appalling array of crimes against humanity. Tellingly Manstein describes the work of the Red Army's political commissars in influencing military decisions and operations, but says nothing at all about the work of their counter-part German political units, whose crimes he was ultimately made to answer for after the war. Taken in context, this is an informative and, at times, fascinating read of significant battles by an important commander. However, it is not by any means a full and frank record of those events.
