Review of Lost Hero of Cape Cod

The Lost Hero of Cape Cod by Vincent Miles revolves around the life of Asa Eldridge and, to a lesser extent, his bothers John and Oliver. The story takes place in that magic period when the age of sail is ending and the age of steam is beginning. The book is written in a narrative style is that really easy to read and understand. Yes, it includes dates, just as any historical book would contain, but the dates often come with relevant back stories that make them seem a lot easier to remember (or at least more interesting to learn about).

Unlike a lot of non-fiction books on history, this one is packed with all sorts of interesting graphics. You do find lots of pictures of ships, which goes without saying. However, the author thoughtfully includes all sorts of other graphics, such as newspaper clippings, pictures of the various characters, pictures of towns,  and even a series of log entries. The result is one of seeing as well as hearing the history the history that took place.

This is a book of fact, not trumped up fiction adorning itself as fact. The list of notes, bibliography, and illustration credits attest to the author’s diligence in learning as much as is possible about events at the time. Even so, the author makes it clear when the sources used are a bit dubious or incomplete. The facts, however, aren’t dry—they’re quite interesting. For example, I had never realized that anyone in their right mind would try shipping ice to India, yet it happened and this book tells you all about it. The manner in which the facts are presented provide a certain intrigue and excitement. You can actually feel the various groups vying for supremacy of the Atlantic and sneering at those who fail.

Most of the material revolves around the Atlantic and focuses on the established route between New York or Boston and Liverpool. However, you’re also treated to the round the world tour made by Cornelius Vanderbilt and his family (captained by Asa Eldridge, no less). Lost Hero of Cape Cod makes ample use of relatively long quotes to let the characters tell you what happened in their own words. Unfortunately, the quoted sections use a slightly smaller and lighter type that can make them a bit harder to read. Even so, you’ll want to read each quote because they’re all important.

About the only complaint that one could make about this outstanding book is that the author tends toward some repetition, especially near the end of the book. Part of the reason for repetition is that the book is topical, rather than chronological in nature. The repetition is easy to forgive, however, because the book is otherwise expertly written.

I’ve purposely left out some important facts that the book presents because I truly don’t want to ruin your reading experience. Let’s just say that Asa Eldridge is far more important as a historical character than you might initially think, yet he’s all but forgotten from the history books. Vincent Miles wants to overcome that oversight with this detailed account of Asa’s life that you’ll find completely immersive. If, like me, you like nautical history, then you really must get this book.

 

Python for Data Science for Dummies Errata on Page 221

The downloadable source for Python for Data Science for Dummies contains a problem that doesn’t actually appear in the book. If you look at page 221, the code block in the middle of the page contains a line saying import numpy as np. This line is essential because the code won’t run without it. The downloadable source for Chapter 12 is missing this line so the example doesn’t run. This P4DS4D; 12; Stretching Pythons Capabilities link provides you with a .ZIP file that contains the replacement source code. Simple remove the P4DS4D; 12; Stretching Pythons Capabilities.ipynb file from the archive and use it in place of your existing file.

Luca and I always want you to have a great experience with our book, so keep those emails coming. Please let me know if you have any questions about source code file update at [email protected]. I’m sorry about any errors that appear in the downloadable source and appreciate the readers who have pointed them out.

 

Python for Data Science for Dummies Errata on Page 145

Python for Data Science for Dummies contains two errors on page 145. The first error appears in the second paragraph on that page. You can safely disregard the sentence that reads, “The use_idf controls the use of inverse-document-frequency reweighting, which is turned off in this case.” The code doesn’t contain a reference to the use_idf parameter. However, you can read about it on the Scikit-Learn site. This parameter defaults to being turned on, which is how it’s used for the example.

The second error is also in the second paragraph. The discussion references the tf_transformer.transform() method call. The actual method call is tfidf.transform(), which does appear in the sample code. The discussion about how the method works is correct, just the name of the object is wrong.

Please let me know if you have any questions about either of these changes at [email protected]. I’m sorry about any errors that appear in the book and appreciate the readers who have pointed them out.

 

Python for Data Science for Dummies Errata on Page 124

Python for Data Science for Dummies contains an error in the example that appears on the top half of page 124. In the first of the two grey boxes, the code computes the results of four print statements. The bottom-most print statement, print x[1:2, 1:2], is supposed to compute a result based on rows 1 and 2 of columns 1 and 2, and the bottom grey box seems to confirm that interpretation by the showing the result as [[[14 15 16] [17 18 19]] [[24 25 26] [27 28 29]]]. However, the answer provided for this example in the downloadable source code is [[[14 15 16]]], which doesn’t agree with that in the text.

The good news is that the downloadable source contains the correct code. The error appears only in the book. The last print statement in the book is wrong. Here is the correct code (with output) for this example:

x = np.array([[[1, 2, 3], [4, 5, 6], [7, 8, 9],],
 [[11,12,13], [14,15,16], [17,18,19],],
 [[21,22,23], [24,25,26], [27,28,29]]])

print x[1,1]
print x[:,1,1]
print x[1,:,1]
print
print x[1:3, 1:3]
[14 15 16]
[ 5 15 25]
[12 15 18]

[[[14 15 16]
 [17 18 19]]

[[24 25 26]
 [27 28 29]]]

Please let me know if you have any questions about this example at [email protected]. I’m sorry about the error that appears in the book and appreciate the readers who have pointed it out.

 

Getting the Fastest Question Response

I always want to be sure that you get fast, courteous responses to your book-specific questions. Even though I don’t check my e-mail every day, I do check it most days of the week, so that’s the fastest way to contact me regarding issues that you have with my books. Of course, you can make the response even faster by doing a few simple things when sending your email:

  • Be sure to include the name of the book and the book edition in the message subject line.
  • Tell me which page, figure, or listing number to look at in the book.
  • Document the steps you took.
  • Provide me with the exact error message you’re seeing.
  • Tell me about your platform (operating system, the version of any software you’re using, and so on).

If you provide these basic pieces of information, I can usually answer your questions much faster—often without asking for additional information. E-mail communication can be difficult at times because it lacks that in person body language element and you can’t show me what you’re seeing on your machine. Remote diagnostics are harder than you might think.

It’s also important that you understand that I focus on book-specific questions. I’ve discussed this issue before in Sending Comments on My Books and Sending Comments and Asking Questions. The bottom line is that I want you to be happy with your book experience, but I also don’t have time to provide free consulting. Please let me know if you have any questions or concerns about contacting me at [email protected].

Review of Shields of PHLEGM

Everyone likes a good laugh and Shields of PHLEGM provides plenty of them. I’m a sucker for a good pun and this book uses them without letup or apology. The author, G. Ernest Smith, also uses satire to effectively poke fun at many of our societies woes without actually addressing any of them directly. No, what you’re left with is a good mystery that takes place sometime in the future when the earth is surrounded by satellites (so there is a science fiction element too). The book isn’t clear on the technology and it doesn’t need to be. The goal is to have a great time and it excels in this area. I actually had to set it down after the first couple of chapters because I ended up with stomach ache (be warned not to read this in a place where you don’t want others to hear you guffaw).

The plot does seem to meander a bit, but really, I didn’t mind. I came to enjoy the character parodies so much that the plot almost became secondary (it does have a good plot, by the way). A few of the jokes became a little old, but not terribly so. The fashion police made nearly constant appearances, which is how they’d probably act, so the behavior wasn’t annoying—it just got a little old. The odd clothing combinations the author came up with really are amazing though and it’s hard to imagine anyone actually dressing that way. Then again, when I see the attire worn by some individuals in public and on television, I must admit the book really isn’t that far off.

I absolutely loved the insulting tone of the smartass phones that made an appearance in the book and have to wonder when such a phone might make a real appearance. Given the things that people are willing to put up with now, I would imagine that this type of smartphone could become a fad at some point—who knows for certain? The fact is that nothing is out of bounds. It sort of reminds me of Blazing Saddles—the author makes fun of everything and everyone with equal punniness.

Some people could possibly take exception to a few bits of language in the book. There isn’t any actual swearing or off color material—at least, it isn’t spelled correctly. That said, you probably don’t want to share this book with anyone underage (not that it was meant for them anyway). This is the sort of book that an adult will enjoy greatly and it truly is adult material.

Is this a good book? Yes, if you like your comedy a bit on the unsophisticated side and really do want a good laugh, then you’ll enjoy this book immensely. Unlike many bits of comedy today, the author doesn’t have to rely on anything unsavory or employ potty humor to get your attention. This book does it the old fashioned way, by viewing the world from a slightly skewed perspective and employing visualizations that really do have you laughing because it’s funny—not because you’re embarrassed. That said, I think the use of a quad ram to act as law enforcement in training was truly inspired. I really do hope this author writes more because I plan to read it. The only real negative about this book is that it was too short—I don’t know that I’ve actually ever said that before.

 

Review of The Last Great Halloween

Nostalgia in all its forms presents us with a colored view of the past that is both wonderful and comforting. The Last Great Halloween is a Trudy McFarlan novel by Rootie Simms that reminds the reader of what it was like to be young in the 60s and 70s. Although the book seems to be written for youngsters, anyone who reads it knows that it’s really meant to let adults remember their childhoods once again. In fact, the idea is actually presented in the book in a manner that I found quite gracious—that Halloween parties for adults let them become children again for just a little while. I’d be surprised if the adults reading the books to their children didn’t end up spending an interesting afternoon or two reminiscing in a way that children actually find attractive. The book is about building bridges, even though it hides its goal in the clothing of historical fiction.

The writing style flows quite well and I quickly found myself caring about the characters—not just Trudy, but all of the children in the story because they all had a distinct role to play. The characters are quite believable, not by today’s standards, but by the standards of children from that time. The cares, concerns, activities, ventures, and prejudices are all firmly rooted in the time. It’s the issue of prejudice that some readers might find a bit off putting, but I found it quite true of the time. There weren’t any societies of the politically correct at the time—people tended to say and act upon what they really believed, right, wrong, or indifferent. For this reason alone, the book truly is more than good fiction, it’s also good history.

A good book entertains, a great book educates—this one does both. However, I found the discussion of sex education as it was presented in the past a little out of place during my first read. I still think the author could have potentially covered some other topic because the sex education incident never appears again and doesn’t actually add anything to the plot of the book. However, the girl’s view of sex education—a ham handed attempt that usually failed to meet its objective, worked well with the boy’s view that I remember from my school days. The incident does serve to remind those of us who grew up then that education of the time wasn’t everything we keep making it out to be. Even then, some things just weren’t covered very well (and sometimes not at all).

Other than the sex education scene (which you can easily skip if you’re easily offended), the book focuses on Trudy’s party. It doesn’t seem at first that a child’s party would make good fodder for a book, but Trudy is at that age where she’s not quite a child anymore and yet, not quite a teenager either—a tween by today’s reckoning. In addition, her friends add some interesting plot twists and the adults chime in to make matters even more complicated. The book is an incredibly interesting read and I can truly say that I didn’t put it down. I can’t often say that I get quite so immersed in a book. (It also helps that this book is a relatively short read.)

By the end of the book, everything is as it should be—Trudy’s party is an amazing success. Of course, you know that before you even turn the first page. It’s the journey that makes the difference in this book. Everything from collecting and turning pop bottles in to get a little extra cash, to the kinds of puzzles that kids gave away during the time are authentic. It’s a happy book. I finished it in a truly good mood.

Is this a good book or a great book? I feel it’s a great book because it does educate as well as entertain. The author has really done her homework about issues of the time—the political forces and upheaval that people faced during the time that we’d find incomprehensible today, all viewed from the perspective of an eleven year old who isn’t sure whether she really wants a party after all. The book does have a few flaws, but they’re easy to overlook because of the entertainment value the book provides. You do need to read the book with an open mind. This is historical fiction so the characters are products of their time. You can’t judge them by today’s standards.

Review of Jamie Collins’ Mystical Adventures: Ninelands

There aren’t as many gentle books today as young readers really need. Most of the books out there today seem determined to teach the young reader about all of the ills of life. In doing so, they often rob the child of his or her childhood. Jamie Collins’ Mystical Adventures: Ninelands (Volume 1) is a gentle story, meant to nourish the young reader’s creativity and provide good entertainment. It’s a delightful story that ties together many childhood characters: Santa Claus, Easter Bunny, and Tooth Fairy. The idea is that all of these characters are elves and somehow associated with Ninelands. Santa actually appears twice in the book and the latter mention adds to the Santa Claus saga. It’s the kind of story that builds a little on what the reader already knows and then adds to it.

The book is theoretically targeted toward the middle school reader and probably hits the mark from a reading grade level. However, this really isn’t the sort of story a middle school reader would enjoy reading—it isn’t a Harry Potter type story (except that both stories involve the use of magic). For example, the protagonists never really go on any sort of adventure or do anything of note except to explore (with help the help of their mentor) this new place. Yes, there is an attack, but the Alvar patrol (the equivalent of the Ninelands military) thwarts the attack, so the characters really aren’t in any danger. Ninelands will appeal more to a younger, early grade school, reader. The manner in which the book is written, the topics discussed, and the overall tone will make a younger reader feel an almost parental comfort during the reading of the story. It’s a story that offers security—throughout the story the author describes the various security measures in place to keep the characters safe.

This is a fanciful book and exceptionally creative. Characters travel around on spoons and within beams of light. They have snake guardians and magic crystals for communication and other needs. Even though the descriptive text lags terribly for the first quarter of the book, the remainder of the book more than makes up for any deficit. A reader is immersed in a world of wonder—of plants that play games and cats that talk. The one glaring omission is a good description of the main character, Jamie. The book never tells the reader what Jamie looks like to any real degree, so it’s hard to draw a mental image of him.

There are also mentions of things that don’t really get used in the book. The problem is that they’re more distracting than helpful in moving the story along. For example, Jamie plays with a dough boy, but the dough boy is never explained and the reader is left wondering precisely how the dough boy comes into play. The dough boy simply is there, probably a product of magic, but the book never says that this is the case, even at the end when the dough boy makes another appearance. Introducing an object, such as the dough boy, should help move the story along in some way.

The children do make a couple of decisions on their own, such as exploring the attic. Still, everything is immersed in an authoritarian environment. Children are constantly reminded of the rules and they always agree to follow them. Little goes on of an adventurous sort and the well behaved children never really do anything on their own. It’s a world that a younger child would enjoy, but an older child would find constraining to an extreme. Even the clown-like mentor, Minkel, takes on an authoritarian air for much of the book (despite spending a considerable amount of time dancing, which also makes him hard to take seriously).

Believability is stretched a little when Mike and Abby, Jamie’s friends, are told they’ll perform a subordinate role to their friend and they simply accept it without so much as a groan. In fact, they seem quite delighted to help their friend. Younger children love to exist in this sort of world, where there is no selfishness and everyone agrees with everyone else. It’s a supportive kind of view that doesn’t exist in the real world. A book for a middle school reader would be more realistic—Mike and Abby would complain, at least a little, and Jamie would complain a bit more about having to allow his little sister, Megan, help.

Some elements of the book do become annoying. The children spend so much time giving high fives and thumbs up in some areas of the book that it’s hard to believe they get anything accomplished. There is nary a frown mentioned in the book, but people are constantly grinning, smiling, and laughing. It is an exceptionally supportive kind of a book, but in some regards, the author goes too far and it’s easy for the reader to become distracted. In some respects, the book needs to feel a little more natural—a little more like the real world—in order to be believable.

There are some areas of the book where there is also a lot of repetition. The plot slows down to a crawl and sometimes stops altogether. The children stop to gawk at some new attraction and Minkel tells them about it, even if the children haven’t asked anything yet. Then come the rules, more rules, and still more rules beyond that. The children always agree to follow the rules, even if they’ve heard the same rules for the tenth time. Again, it’s the sort of environment that a younger child would enjoy, but I can hear a middle school reader screaming in frustration at some points in the book.

Is Ninelands a good book? Actually, it’s a really good book if you’re in the lower grades of grade school and have someone to read it to you. The fanciful world is quite appealing and I can see younger children getting quite caught up in it. After the first quarter of the book, the level of description really is quite good and I can see it helping the younger reader create mental images of what this wonderful world must be like. I really like the fact that this book doesn’t repeat the same tired vistas found in many other books—there are surprises and new things to explore. It’s the sort of book that a younger child will want read more than once because you really can’t get everything out of the text with just one reading. If you have a younger reader, you really do want to explore Ninelands because it’s fascinating place to visit.
