New Look! New Features!

If you’re visiting my blog for the first time this year, you probably noticed a few changes in its appearance. Sometimes a site changes its appearance simply to provide a different look—to enhance its aesthetic appeal. It’s true that I had used the previous design for a number of years, but that’s not the reason for the changes you see today. These changes come as the result of input from the people who read my blog and took the time to comment on it.

The biggest change is one that you can’t readily see until you access my blog from a smartphone. My site now works well with devices of all sizes so that you can gain access to the information my blog provides from any location using any device. It took me a while to find a theme that I thought would preserve most of the look and feel of the original blog, but allow for this added functionality. Even though the feel is a little different, the addition of this feature is important to enough readers that I really want it to work well.

As part of making my blog easier to use, I also went for a cleaner look. The new format should work in a wider range of settings, even in bright sunlight (as well as anything works in bright sunlight). The larger type should also make it easier for people with special visual needs to see. I tested the new setup out on a number of monitors and find that it scales better than the old design too.

Part of the update also affects my web site. I wanted to provide better consistency between the two locations. Some viewers said it was a bit disconcerting to use one layout on the web site and another on the blog. My original intent had been to provide the best layout for each setting, but this method of configuring the two locations didn’t work nearly as well as I thought it would.

Of course, I always want your input because this site is specifically designed to meet your needs. I want the readers of my books to get maximum benefit from them, which means having a blog that actually meets those needs. If you see what you like or want to express concerns about issues you don’t like, please feel free to contact me at [email protected]. As always, your input is essential to the success of my books, my blog, and my other endeavors!

During the upcoming months I do plan to make additional changes. The blog has gotten a bit unwieldy, so I plan to remove some existing content to make room for new information. I’ll also be adding more linkage between my web site and the blog so that the two work better together. Your patience during this time of transition is greatly appreciated!

 

Missing XMLData2.xml File

A number of readers have written to report that XMLData2.xml is missing from the downloadable source for Python for Data Science for Dummies. You encounter this file in Chapter 6, on page 108. The publisher has already added the file to the downloadable source, but you might be missing the file from your copy. If so, you can download it by clicking XMLData2.zip. I’m truly sorry about any problems that the missing file might have caused. Please be sure to let me know about your book specific question at [email protected].

 

The Internet – The Home of Old Data Made New

I have to admit to making this error myself.  I’ll perform a search online and fail to fully check the freshness date of the information I obtain. Of course, there are several levels of freshness date to consider. The first level is the information source. This is the easiest level of data to check. You simply look at the date of the material when you get to the page. Unfortunately, some authors don’t date their work, so you can’t always rely on a posting date. The next best alternative is to ask the search engine to list only those entries that come from a certain time frame. In most cases, you can verify that the information appearing in an article or other posting is current enough for your needs.

Unfortunately, just verifying the posting date may not be good enough. The second level of check is the version of the products discussed as part of the post. For example, you might come to my blog and find a post on CodeBlocks. Unless you read the article carefully, you might think that I’m discussing the latest version of CodeBlocks. However, I have a number of books that rely on CodeBlocks, so I might actually be discussing an older version of CodeBlocks that I used in a specific book. Reading carefully and ensuring you understand version issues is the best way to verify this second level of information.

A third level of freshness checking is the information sources used by the author. This is where things get tricky because the author could truly think that the information source used for an article is the most current available, yet it’s outdated before the author even uses it. Some technologies change so fast that using a resource even a few months old is deadly. These resources become outdated so quickly that they can blindside even a professional author, much less someone who writes on the side. Verifying this level of information requires that you depend on at least three information sources (I recommend finding as many as you can). Gently nudging an article author and mentioning that the information sources might contain outdated material is often helpful when done in a constructive manner.

Freshness checking can occur at even deeper levels. The point is that you can’t be sure that a resource that keeps information literally forever contains the latest information on any given topic. In addition, even when that information is available, it’s up to you to find it. I do try to provide the latest information available when I can. However, when the topic is a question on an older book, I need to address the question in the context of that book and will provide you with some sort of version information so you know what to expect. If you ever question the freshness of the information I provide, please feel free to contact me at [email protected].

 

Predicting Processed Rabbit Weight

One of the issues that faces someone who raises meat rabbits is how to predict the dressed or processed weight of the rabbit based on the live weight. After all, you can’t add more weight after the fact. First of all, you need to weigh the rabbit before you feed it, rather than after. Using the before feeding weight seems to provide more predictable results. I’ve found that rabbits can be picky eaters at times, so using this baseline ensures I’m not weighing different amounts of ingested food. Couple the before feeding weigh-in with a same time of day feeding time to ensure you get predictable results. (I also feed right before sundown because rabbits are nocturnal and will feed better at night.) However, there is always some variance, so you need to expect some range in the dressed weight of the rabbit.

Younger rabbits tend to dress out at a higher percentage of their live weight. Most people wait at least eight weeks before attempting to process rabbits. However, these younger rabbits are also considerably smaller than a more mature rabbit. Waiting until thirteen to fifteen weeks often produces a nicer rabbit even if the live weight to processed weight ratio is smaller.

What you feed the rabbit will also make a difference in the ratio because some types of food tend to produce more fat, than lean meat. Adding corn or other grains to the feed will cause the rabbit to be more tender and grow faster, but at a lower ratio and with more inner fat (the fat that isn’t removed with the skin). When you feed anything other than alfalfa pellets, you change the texture of the rabbit and its fat content, and therefore the ratio of live weight to processed weight. For example, feeding the rabbit grass will tend to make it leaner.

The kind of rabbit can also make a big difference. A New Zealand rabbit may only provide a ratio of 55% live weight to processed weight, while a Dutch can provide a ratio as high as 60%. Mixed breed rabbits increase the uncertainty of yield, but do provide advantages in genetic diversity, which can improve the taste of the meat and reduce the need to use medications that pure bred rabbits could require. In short, you need to consider the trade-offs of various decisions you make during the entire process.

In general, you can expect a ratio as low as 50% for a mixed breed rabbit and somewhere around 65% for a Californian/New Zealand mix. However, you must take all sorts of other factors into consideration as previously mentioned. To help me calculate the processed weight better, I started to keep records of live weight to processed weight ratios, ensure I fed the rabbits the same diet, and kept my stock as close as possible to the same mix. Even so, I find that each processing session provides slightly different ratios. Let me know about your live weight to processed weight insights at [email protected].

 

Colorful Carrots

The carrots go by many different names, but the main idea is that they’re quite colorful. I have now tried two different kinds, Carnival and Rainbow. Both kinds produced yellow, orange, red, and purple carrots. The Carnival variety pictured below also produced white and, oddly enough, one green carrot. I’m pretty sure the green carrot was due to some oddity in the seeds (or possibly it was introduced to sunlight in some manner). They both produced tasty carrots where the color definitely affected carrot taste. Of the two packages, I obtained the largest carrots from the Rainbow packet, but a single season doesn’t truly provide enough testing time to say that this would always be the case. I may simply have had an exceptional year. I plan to buy one packet of each sometime and plant them in the same area of the garden in the same year so I can perform side-by-side comparisons.

Colorful carrots make for exceptional meals.
A Colorful Array of Carrots

The carrots weren’t just colored on the outside. Cutting the carrots showed that the white, yellow, and orange carrots were the same color all the way through. The red carrots were red on the outside and orange in the inside. The purple carrots proved the most interesting, with bands of purple, orange, and yellow. Eating the carrots raw proved to be a real joy because you got different flavors with each bite and adding a dip (such as ranch or blue cheese dressing) simply added to the variety.

Growing colorful carrots means seeing color both inside and out.
Carrots Can Vary in Color Inside and Out

Cooking the carrots will change the color of the red and purple carrots to a dark orange. The white carrots do take on an orange cast, but you can still tell they were originally white. The same holds for the yellow carrots—they grow a bit more orange, but are most definitely remain lighter than the orange carrots. Therefore, even when cooked, you end up with a colorful meal, but not quite as colorful as the raw carrots. The colorful carrots even can well. The taste differences between carrots tends to fade a little when cooked and even more when canned. I can still tell the difference between these carrots when canned and other, pure orange, carrots.

Even the canned version of the carrots are colorful.
Canned Carrots Retain Some Color Differences

Unlike many multi-colored vegetable choices, getting multi-color carrots will provide you with enjoyment throughout the year. I now have some colorful choices for a variety of uses this winter. Let me know your thoughts about colorful vegetable choices 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.

 

Tip Error in Python for Data Science for Dummies

There is a small error on page 318 of Python for Data Science for Dummies. You can find it near the middle of the page in the Tip text. The current text on the second line of that paragraph says, “k as a number near the squared number of available observations.” However, the text should really read, “k as a number near the squared root number of available observations.” The word root is missing, which obviously changes the mathematical meaning of the text. Please accept our apologies for the typo. Let me know if you find any other errors of a technical nature in the book at [email protected] and I’ll be sure to provide a blog post about it here. Thank you for your support!

 

Pullet Update – Current Egg Sizes

The fall brings a series of events that make for interesting visits to the coop looking for eggs. Because I have a mixed flock, there is a combination of pullets and hens out there. The hens haven’t been laying many eggs as of later because they’re molting. The pullet eggs are just now starting to get big enough to really count for something. I still get super jumbo eggs from my Buff Orpingtons. These eggs peg my scale and don’t actually fit well in the carton (even with jumbo cartons, I find I must exercise care in even trying to close it). The Buff Orpingons are the only birds who lay these rather huge eggs.

These super jumbo eggs don't quite fit most cartons.
Super Jumbo Eggs Peg the Scale

The Americauna eggs can get quite large too. The advantage of the Americaunas is that they produce more eggs and eat a bit less than the Buff Orpingtons. Plus, they have these really pretty blue eggs.

The Americaunas produce extra-large to jumbo eggs on a regular basis.
Americaunas Product Beautiful Blue Eggs

At this point, I’m getting eggs in every possible size. You can see the difference in sizes from small on the right to super jumbo on the left. The eggs are always measured by weight. In addition, I check my eggs individually, so a carton that is listed as having large eggs has all large eggs in it (when you buy eggs in the store, the eggs are measured by overall carton weight, which means that you might have a mix of medium, large, and extra-large eggs in a single carton).

Weighing eggs individually is the only way to get consistent carton size.
Eggs Vary Considerably in Size

Even though the medium egg (second from right) looks similar in size to the large egg (directly in the middle), they weigh differently. It’s not always easy to tell just by looking at an egg how much egg you’re actually getting. Of course, the size of your egg can affect the outcome of a recipe (which is why I’ve gone to weighing my eggs as described in Pullet Eggs and Cookies. Let me know about your experiences with various egg sizes at [email protected].

 

Remembering to Rest (Part 2)

It’s important to rest—to stop working for a while and to do something different, something enjoyable. In Remembering to Rest, I talked about Wildcat mountain, a favorite place to go in the fall to unwind a bit after a summer of hard work in the garden. Once the work gets to that magic point where it’s possible to take a little break, reflecting on the summer is a good way to get ready for the rigors of winter. This year I went to Wildcat mountain a little later than usual because the weather has been warmer than normal and it takes me a bit longer now to get to that magic resting point.

Of course, my first stop after my picnic lunch is observation point. I went to Wildcat Mountain on a Tuesday, so I more or less had the park to myself. Yes, there were other people, but we all seemed to sense the need to respect each others’ privacy. I did ask one young lady to take my picture at observation point. As you can see, the fall colors are past their peak, but it’s still a beautiful view.

I took my Old Settler’s Trail hike. It’s a 2.5 mile trail that I’m sure some people would consider a bit mundane, but I find it plenty exciting and more than a little exercise. The 1.5 to 2 hour hiking time only counts if you’re in shape and I definitely don’t recommend the trail if you have a fear of heights or any problems whatsoever walking. I finished the trail in one hour and 43 minutes this time—not my best time, but I took extra care because I was alone on the trail. Of course, the first thing you see on this trail are the steps down. I took this picture looking back up the steps once I got to the bottom.

Looking back up the first set of steps.
Looking back up the first set of steps.

Most of the hike is on uneven ground, but the trail is clearly visible. Staying on the trail is a good idea because you don’t really know what you’ll encounter otherwise. I saw quite a bit of wildlife, including a beautiful buck who refused to allow me to take his picture. One of my favorite places along the trail is the foot bridge over a creek. It’s a nice place to take a few moments to rest and just enjoy the gorgeous scenery.

This footbridge goes over a small creek and provides a wonderful view.

The trail does provide resting points. You do need to climb up to them. However, they do provide wonderful views of the countryside while you rest.

The resting places provide a beautiful view of the countryside.
Step Up to a Resting Place

For me, the highlight of the hike is Taylor Hollow Overlook. The view isn’t quite as amazing as those provided by some other Wisconsin parks, but you really can see quite a distance and when the colors are just right, the patchwork is really quite colorful. By this point in the hike, a lot of people are starting to get a bit tuckered out, so this particular bench doesn’t require any climbing. You can just sit and enjoy the view.

A place to sit down for a while and enjoy the view.

It’s at this point where you might want to turn around if you suffer from any vertigo at all. The trail becomes steep and there are no handholds to speak of. The drop would likely result in broken bones or other injury. The point is that you want to take care to traverse this part of the trail with great care.

A combination of steep steps and no handholds makes this part of the trail difficult.
Step Steps and No Handholds

It isn’t long after you get past this part of the trail that you loop around and rejoin the trail you originally used to get down the steps shown in the first picture. This time you go up the steps. By the time you’re finished, you’ll likely be a bit out of breath and will definitely know you’ve had a workout. Still, what a place to workout!

When Brown Sugar Isn’t Brown

This post has been updated to include links to some of the resources I used during writing. A few readers rightfully took me to task for not including any resources. Thanks for keeping me honest!


 

A reader recently queried me about a post I made some time ago entitled, Replacing Salt and Sugar with Herbs, Spices, Color, and Texture. In this post I talk about methods you can use to reduce your salt and sugar consumption. I’ve gone a lot further since then in reducing my salt and sugar content. Of course, you need a little of each item in your diet. Whether you need to add either item to your food is a matter of personal taste, but you can usually get enough of booth just by eating a balanced diet. Salt is an absolute in many respects. Yes, you can eat sea salt and get some other minerals with your salt, but basically, salt is salt. However, sugar is different. When viewing sugar, you need to consider both the kind of sugar and the amount that the sugar is processed. It’s the latter item that is the topic of this post. Most notably, brown sugar.

Like most people, I look for ways to save money at the store. So, for a while I was buying just any old brown sugar-the least expensive I could find. However, I’ve taken to actually reading labels. This is only something that I’ve decided to do recently though. Reading the labels of a product is actually a lot easier when you can clearly see its ingredients and any other important information you may need to decipher whether you should purchase it or not. My friend thought that it was because the manufacturer had enlisted the help of a Paul Leibinger inkjet printer. He told me that Leibinger manufactures high quality inkjet coding and inkjet marking systems for industrial labeling of products and packing, which can help companies to clearly mark their products with things like the batch number and best before date – which is information that could help benefit us in our purchases. It has definitely helped me with deciding which sugar to buy. When you review the list of ingredients for most brands of inexpensive brands of brown sugar, you see sugar and molasses as the ingredients. What this really means is that the vendor has highly processed the sugar, making it into white sugar, and then colored it brown using molasses. What you’re getting is a processed product, not a rawer form of sugar. What you really want to see on the label is one ingredient, brown sugar.

The reason for this post is that actual brown sugar is different from white sugar mixed with molasses. Creating a rawer form of the sugar makes a difference in its texture and how it bakes. Yet, most of the material I’ve read online seems to assume that every kind of brown sugar out there is simply white sugar mixed with molasses. The less expensive forms of brown sugar are moister and tend to taste just a bit caramelized. In addition, what you may be getting is beet sugar, not cane sugar, when you buy the less expensive brands. The less expensive brown sugars may not even be brown all the way through the crystal, which tends to change the result you get.

As to whether there are any health benefits to using real brown sugar, I’ve read a few bits of research that seem to indicate that the real brown sugar has a few extra minerals. However, if you’re diabetic, you still need to take the same precautions with brown sugar that you take with white sugar (or any other sugar). The main differences that you’ll notice is that the items you make with real brown sugar will tend to taste better and your baked goods will come out better. The important thing is to make an informed choice. Choose to read product labels before you purchase items in the store and then take a little time to research what these ingredients are all about. Let me know your thoughts about real brown sugar versus white sugar sprayed with molasses at [email protected].
