What Am I Reading?

Readers often write to ask me what I’m reading. It’s a hard question to answer in some respects because I have a broad range of interests and I often find myself reading more than just one text. However, it’s a valid question and concern because what I read eventually affects the content of the books that I write and that you read. I strongly believe that the most successful people in life are voracious readers as well. Of course, there are likely exceptions (and please don’t fill my e-mail with listings of them). Reading opens doorways to all sorts of new worlds and different ways of seeing things.

It won’t surprise you to discover that I do quite a bit of technical reading. Every day sees me scanning articles from eWeek, ComputerWorld, and InfoWorld (amongst others). I also regularly read a variety of magazines—some quite serious like MSDN and Dr. Dobbs Journal, others a little less serious like PC Gamer. I also technically edit some books every year and read them end-to-end. Sometimes I read a book simply because I want to learn something new. Currently I’m exploring Rod Stephens’ Essential Algorithms (an outstanding book that I’ll review at some point).

Given the content of this blog, it shouldn’t surprise you to discover that I also read a number of gardening magazines such as Mother Earth News and Horticulture (again, there are others). I usually read books from publishers such as Storey. It wasn’t long ago that I completed reading Storey’s Guide to Raising Chickens. Of course, I look for articles online as well.

What you may not know is that I also enjoy reading other sorts of books and magazines. For example, I’m currently engaged reading the Patrick O’Brian novels for the sheer pleasure they bring. Captain Aubrey is turning into a favorite character of mine. National Geographic and Smithsonian are both monthly magazines that I read. I keep up with what is happening in the Navy by reading Seapower. Rebecca and I also enjoy a number of crafts and we read some of the same crafting magazines.

As you can see, it’s quite an odd assortment of materials and I love it all. The vistas opened by the materials I read help me provide you with better material that is both more creative and easier to understand. You don’t have to have the best education in the world to succeed. All you really need is a strong desire to find the information you need when you need it. The more you read, the better you understand the world around you and the better prepared you are to take advantage of the vast array of reading resources at your disposal when you need them.

It’s important to know that the authors you read are also well read—that they make use of all of the available materials to write better books. Experiencing the world through the written word is an essential part of the learning process. Today we have all sorts of multimedia presentations vying for attention with the written word, but in many respects writing isn’t easily replaced because it brings the world to you in ways that other forms of media can’t. Of course, that’s a topic for another post. Let me know your thoughts on the importance of reading at [email protected].

 

Controlling the Body

It surprises me when I think about all the injuries that leave a body part perfectly usable, but unreachable. An arm would still work if the brain could contact it, but something prevents that contact. In some cases, the loss of contact is permanent and is reestablished though physical and occupational therapy. However, in other cases, the loss of contact is permanent and another solution for creating that contact must be found. Both scenarios have seen technical improvements as of late.

As an example of the first, where contact is temporarily lost, students have been experimenting with techniques for taking control of someone else’s limbs. When I first read this article I thought about the scary implications that loss of control can present. However, what if the person doesn’t actually have control? A therapist could take control of the limb in order to help a patient regain control or to make it easier to exercise the limb in a natural way so there is less loss of muscle mass. Both uses are important. Using a person’s own muscles to help them move around and become reacquainted with their body after a severe accident makes sense especially when you see some of the convoluted measures that therapists must use now to work with a patient from the outside.

As an example of the second, where contact is permanently lost (or the limb is actually missing), science is starting to figure out how to create new connections. For example, it’s now possible to connect a robotic leg that a patient controls using the same brain waves that a leg would naturally use. The technology is currently in its infancy, but progress is being made. In another five or six years, it might be possible to see people who have permanent loss of contact with a limb or the need to use artificial limbs walking around without any problem at all.

It’s exciting to think of the possibilities. Both technologies will make it a lot easier to help someone with special needs regain full mobility. Ultimately, the incapacitation or loss of a limb will become less life changing. Yes, there will be some amount of time spent in rehabilitation, but the change won’t be permanent. Of course, it’s going to be a long time before even these technologies will help someone do anything too dramatic—basic walking and possibly light jogging will have to be enough. Would you allow someone take control of your limbs in order to help you regain your full capacity? Let me know at [email protected].

 

The Science Fiction Effect

I love reading science fiction. In fact, one of my favorite authors of all times is Isaac Asimov, but I’m hardly unique in that perspective. For many people, science fiction represents just another kind of entertainment. In fact, I’d be lying if I said that entertainment wasn’t a major contributor toward my love of science fiction. However, for me, science fiction goes well beyond mere entertainment. For me, it’s a motivator—a source of ideas and inspiration. So I recently read A Warp Speed Analysis on the Influence of Science Fiction with a great deal of interest. It seems that I’m not alone in my view that science fiction authors are often a source of creativity for real world scientists who see something that could be and make it into something that really is.

The science fiction effect has inspired me in both my consulting and writing over the years. For example, I’ve seen how science fiction authors treat those with special needs as if they don’t really have any special need at all—science has provided solutions that level the playing field for them. It’s the reason that I wrote Accessibility for Everybody: Understanding the Section 508 Accessibility Requirements and continue to write on accessibility topics. The whole idea that science could one day make it possible for everyone to live lives free of any physical encumbrance excites me more than just about anything else.

What I find most interesting is that the ability to turn science fiction into science fact receives real world emphasis by colleges and universities. For example, there is a course at MIT entitled, MAS S65: Science Fiction to Science Fabrication. Many articles, such as Why Today’s Inventors Need to Read More Science Fiction, even encourage scientists to read science fiction as a means of determining how their inventions might affect mankind as a whole. The point is that the creativity of science fiction authors has real world implications.

Now, before I get a huge pile of e-mail decrying my omission of other genres of writing—I must admit that I do read other sorts of books. Currently I’m enjoying the robust historical fiction of Patrick O’Brian. I’ll eventually provide a review of the series, but it will take me a while to complete it. Still, other books focus on what was in the past, what is today, or what possibly might be—science fiction propels us into the future. The science fiction effect is real and I’m happy to say it has influenced me in a number of ways. How has science fiction affected you? Let me know at [email protected].

 

Potential Commercial Uses for 3D Printing

A technology can have significant appeal without becoming a mainstream technology. In my post, Thinking About 3D Printing Technology, I discuss some of the implications of 3D printing, including it’s use for accessibility. The 3D Printing Technology Safety post discusses the associated safety concerns with using the technology. However, both viewed 3D technology as just that—technology. In order for a technology to make a significant inroad, it must have a critical mass and one of the means to obtain that is to make a commercial product.

There aren’t any such products today. You can’t go to a store, order a new set of plates, and watch them print out before your eyes. That sort of thing could happen someday, but not quite today (imagine a set of plates where each family member has their picture in the bottom). I recently came across two articles, though, that hold promise for the future.

The first is quite practical and something I foresee being printed in the home, a sweater. The sweaters aren’t available yet, but the article’s author is looking for people to invest in her idea (at $189.00 a pop). The sweaters are supposed to become available by September 2014, which isn’t that far away when you consider the time required to obtain some new technologies. I’m expecting these first efforts to be not quite perfect, but they’ll improve rapidly. The advantage of a printed sweater is that you can create it to match your body perfectly.

The second is an interesting new car named the Urbee. Not everything in the car is printed, but from what the article has to say, a vast majority of it is. The advantage to a designer is that you can print car parts a lot faster than you can build them using other techniques, so it becomes possible (and economical) to play with a car’s design more so you can optimize it. The vehicle looks a bit odd, but most people could probably get used to it. What’s most interesting about this car though is that it gets 300 mpg with a top speed of 70 mph.

These two commercial products are probably just the tip of the iceberg. It would be interesting to find out if there are most such products in the works. Even better, having a crystal ball so you can see what’s going appear in the future would be amazing. For now, I’ll simply be happy to hear about the uses for 3D printing technologies that you’ve seen. Let me know at [email protected].

 

An Avoidance of Technology

As an author, I’m always interested in hearing how people use technology to better their lives or as a means of entertainment. However, I’m just as interested in the non-use of technology. In fact, there are people who outright avoid technology or keep their use of technology at a certain level and I find that learning about these people makes me a better author. For example, I recently read about a family that won’t use any technology newer than 1986. A number of other people are discussing the avoidance of technology for technology’s sake as a means of creating a more sustainable environment. Some people equate these kinds of movements as a backlash against technology, but that truly isn’t what’s happening here. These people aren’t some new age Amish who choose to ignore certain technologies as part of a religious conviction. What is really happening is that people either fail to see a need to embrace certain technologies or they have chosen to use only the technologies that serve a specific need in their lives.

It’s currently estimated that 15 percent of Americans don’t use the Internet because it doesn’t make sense for them to do so or they lack access in some way. Interestingly enough, 9 percent of Americans don’t have cellphones of any type. There are many reasons for not having a cellphone, but in many cases it’s a personal choice. Even if the person had access, they wouldn’t want the cellphone because it would interfere with their lifestyle. The assumption that everyone owns a smartphone (essentially a computer sized down to fit into a cellphone body) is also incorrect. Only about 56 percent of Americans have a smartphone now. All these statistics, and many more, point to the idea that not everyone embraces every technology and there are many reasons for not doing so.

All of my books to date have assumed that someone has embraced a particular technology and wants to know about it. However, while many people assume that the potential reader has lots of experience with technology, my lower end books usually don’t make this assumption because many people are still adapting to technology. I also don’t assume the use of technology is a personal desire—many people use technology solely because of a job requirement.

The reason this post is important to you is that it helps to explain some of the things readers have questioned me about in the past. The question of why it’s important to explain a concept at a certain level hinges on the audience I’m addressing. Within this audience are people who have no experience and a low level of desire to interact with the target technology, so I must ease them into learning what they need to know. Unfortunately, the very act of easing some people into a technology offends other people who openly embrace a technology and were really looking for the short explanation for a technology. It’s hard for any author to find the precise mix of information that will meet the needs of the broadest range of readers possible and there will always be some level of disappointment for many readers.

Trying to figure out precisely how to present information to my readers is important to me. That’s why your input is so important. Always feel free to let me know how you feel about the coverage of technology in my books. I can’t guarantee that I’ll be able to change the manner in which I cover technology, because I’m always faced with competing interests between readers, but I’ll always listen to what you have to say and make changes as appropriate. Are you avoiding technology? Let me know why at [email protected].

 

Printing the Blog Posts

A number of readers have written to express their desire for printable blog posts. I feel your pain. If I had a nickle for every piece of paper wasted trying to print something found on a site somewhere, I’d be a rich man. On some sites, it just isn’t possible to print the content without dragging a lot of extra material. Just a little bit of material ends up consuming several printed pages and sometimes you can’t get a good printout no matter how hard you try. Yes, it’s quite frustrating.

Fortunately, it’s easy to print my blog posts without all of the extra material. Start by clicking the post title link (when viewing multiple posts in the list format). You’ll see the post presented by itself. The title text is a little larger in this format and you have the ability to add comments to the post as needed. However, look down at the Posted by entry at the bottom of the page. Next to that entry is the name of the poster (me), the date and time of the posting, and a little printer icon.

When you click the printer icon, you’re taken to another page that shows the post in plain text without any of the fancy formatting. The printer dialog for your system also opens so that you can choose a printer to use. All you need to do at this point is tell your system to print the post and you should see a plain text version appear at your printer.

I know this particular setup works well with my systems and I’ve tested it with Firefox, Chrome, and IE. However, if you encounter problems printing a post, please let me know at [email protected]. I’ll do my best to find a solution for you so that you can output the post to your printer.

 

3D Printing Technology Safety

A number of people have written to comment about the Thinking About 3D Printing Technology post. Obviously, I still have a lot to learn about this technology and some of your questions have taken me quite by surprise (I’ll address some of them later, after I have conducted more research). I always appreciate it when you make me think through the topics I post because the conclusions I reach often make great fodder for book topics.

The one question that didn’t take me by surprise was one of safety. After all, it’s important to know that the output you create is safe. At the time I wrote that post, there was little on the topic of safety, which is why I didn’t include any sort of safety information. A recent article entitled, “3D-Printed Medical Devices Spark FDA Evaluation” tells that the issue of safety is on a lot of other people’s minds as well. The problem for the FDA is that it can’t actually test a printed medical device in any meaningful way and still allow a hospital to use the device in a reasonable time frame (such as in an emergency room), so it allows use of these printed devices on the basis of similarity to devices it has tested thoroughly. In other words, the printed output must match an existing device, except that it provides a custom fit for a particular patient.

I thought about that article for quite some time. It seems to tell me that the FDA is reviewing the issue of safety, but hasn’t come to any final conclusions yet. What I’m trying to do is weigh articles like this one against other articles that decry the complexity and problems of using 3D printing technology. For example, 3D printing: Don’t believe the hype states outright that many of the plastics used for 3D printers aren’t even food safe. I’m assuming that the FDA requires hospitals that rely on this technology to use the correct, safe, materials. Even so, the article does make one wonder about the safety of the materials provided for consumer-level products. Not many people will be able to afford a hospital grade device.

Safety extends beyond the end product, however, and this is where a true scarcity of information occurs. For example, when you melt some plastics, the process produces Hydrogen Cyanide (HCN), which is an extremely dangerous gas. I thought it fortunate that I found an article on the topic entitled, “Is 3D Printing Safe?” The short answer to seems to be yes, 3D printing is relatively safe, but you’ll want to ensure you have proper ventilation when doing so.

This whole issue of safety does concern me because new technologies often have hidden safety issues that are later corrected after someone encounters them (usually with unfortunate results). Like any tool, a 3D printer isn’t a toy—it is a device for creating some type of specific output. For the most part, I’d recommend against letting children use such a device without parental supervision (preferably by a parent who has actually read the manual).  I’d like to hear more of your concerns about 3D printing at [email protected].

 

Continuing Education

I don’t know if you’ve noticed, but I’m continually asking questions in my blog posts. In fact, you can find questions in a few of my books and more than a few readers have commented when I ask them questions as part of my correspondence with them. I often get the feeling that people think I should know everything simply because I write books of various sorts. In fact, I had to write a post not long ago entitled No, I Don’t Know Everything to address the issue. Experts become experts by asking questions and finding the answers. They remain experts by asking yet more questions and finding yet more answers. Often, these answers come from the strangest sources, which means that true experts look in every nook and cranny for answers that could easily elude someone else. Good authors snoop more than even the typical expert—yes, we’re just plain nosy. So, here I am today asking still more questions.

This year my continuing education has involved working with the latest version of the Entity Framework. The results of some of my efforts can be found in Microsoft ADO.NET Entity Framework Step by Step. You can also find some of my thoughts in the Entity Framework Development Step-by-Step category. I’ve been using some of my new found knowledge to build some applications for personal use. They may eventually appear as part of a book or on this blog (or I might simply choose to keep them to myself).

However, my main technical focus has been on browser-based application technology. I think the use of browser-based application technology will make it possible for the next revolution in computing to occur. It certainly makes it easier for a developer to create applications that run anywhere and on any device. You can find some of what I have learned in two new books HTML5 Programming with JavaScript for Dummies and CSS3 for Dummies. Of course, there are blog categories for these two books as well: HTML5 Programming with JavaScript for Dummies and Developing with CSS3 for Dummies. A current learning focus is on the SCAlable LAnguage (SCALA), which is a functional language (akin to F# and many other languages of the same type) based on Java.

Anyone who knows me very well realizes that my life doesn’t center on technology. I have a great number of other interests. When it comes to being outdoors, I’ve explored a number of new techniques this year as I planted some new trees. In fact, I’ll eventually share a technique I learned for removing small tree stumps. I needed a method for removing stumps of older fruit trees in order to plant new trees in the same location.

I’ve also shared a number of building projects with you, including the shelving in our larder and a special type of dolly you can use for moving chicken tractors safely. Self-sufficiency often involves building your own tools. In some cases, a suitable tool doesn’t exist, but more often the problem is one of cost. Buying a tool from the store or having someone else build it for you might be too expensive.

The point I’m trying to make is that life should be a continual learning process. There isn’t any way that you can learn everything there is to learn. Even the most active mind picks and chooses from the vast array of available learning materials. No matter what your interests might be, I encourage you to continue learning—to continue building your arsenal of knowledge. Let me know your thoughts on the learning process at [email protected].

 

Every Move You Make, Every Breath You Take, They’ll be Tracking You!

I read a ComputerWorld article recently entitled, “So what’s wrong with being tracked by advertisers?” that really makes me uncomfortable. The author describes scenarios whereby advertisers could track your every move-up to and including your bathroom habits. Such complete tracking doesn’t seem doable today, but the author’s arguments really do make such tracking seem like a reality that is about to happen. Of course, the question that comes to my mind immediately is whether the author is sincere in stating that only advertisers should be able to perform tracking at this level. It’s naive to think that governments and others won’t use the same technology to their advantage. For example, consider the crook who tracks your movements and holds you up immediately after you cash a check or obtain some other source of money to maximize their haul.

The article is eye opening because apparently, some companies are already involved in this behavior to some extent. My Tracks seems like an interesting app for your smartphone until you begin thinking about the implications. Any signal sent out by any device is capable of being intercepted by anyone, including that person down the street who makes you feel really uncomfortable. It makes me wonder why anyone in their right mind would install such an app in the first place.

Don’t get the idea that smartphones and other sources of electronic emission are the only potential tracking devices. Your computer makes it possible for someone to create a thorough profile of your behaviors and to track your activities to a point that you’d probably find unbelievable. Most people realize that browsers use cookies to track them, but you’re open to tracking in so many other ways. The InfoWorld article, “Anonymous is not anonymous” makes it clear that the best attempts to hide your online activities are completely worthless. The movie view of the “ghost hacker” is a myth today (if it ever existed at all).

It isn’t just computers either. The rewards card that your supermarket or drugstore issues likely has a Radio Frequency IDentifier (RFID) tag in it that makes it possible to track your precise movements through the store. The fact that RFID is passive technology makes it particularly onerous because you have absolutely no control over its use.

People have to start thinking about securing their privacy in the same way that others think about peering into their every activity. A recent article, “Hacked wireless baby monitor lets pervert spy on and cuss at baby girl” shows just how far other people are willing to go to pry into your life and turn it upside down. You can read about other sorts of appliance-based spying in the article, “Your Home Appliances May be Spying on You.” This sort of activity happens regularly now and not just from companies, but from hackers as well. Hackers may be spying on you right now through your home security system if it contains any wireless elements at all. And they may even do this to find the best time to break in, which achieves the opposite of what the system is supposed to prevent. Fortunately, many people look into security measures that can’t be compromised as such. For example, Riot Glass windows or secure doors to prevent break-ins. Wireless security systems that have strong passwords and access permissions can prevent hackers from spying, though the company that supplied them may still be able to farm data. All in all, you really do need to consider what you’re giving up by losing your privacy. A recent article entitled, “Noonan: What We Lose if We Give Up Privacy” provides great food for thought on the issue.

I don’t mean this article as a scare tactic. What I want to do is arm you to think about your privacy and security in light of the gadgets that you use. My post, An Unreasonable Expectation of Privacy, received quite a bit of attention and I received more than a few emails about it. Some people felt that I was making up some of the issues I discussed in that article. It truly is hard to believe that things have become so bad, so fast. However, your privacy is in your own hands. If you want to keep a secret, then don’t tell anyone about it. Likewise, if you don’t want someone to know your location, leave your cellphone at home. If you don’t want someone to spy on you, make sure your home security system doesn’t have any outside connections or rely on wireless communication. Yes, the solution to the problem is inconvenient and frustrating, but that’s the only solution you truly have. Let me know your thoughts about tracking at [email protected].

 

Management Lessons from the Military

Having spent 10 years in the Navy, I know that military life can provide some benefits that translate well into civilian life. Enforced discipline, often described as training, does create an environment in which you can learn how to perform tasks more efficiently and with greater success. The training isn’t always comfortable, but the feeling of success when the training is over is always amazing. That’s why I went through the Ten Workplace Lessons From the Military slideshow on Baseline with great interest. It actually does help you understand how someone who has had military training can provide significant benefit to an organization of any sort.

From a personal perspective, I credit my military training with giving me drive and ambition required to write books and to also work through many of the issues in self-sufficiency that I have. The techniques that I learned in the service have translated well into creating an environment where I can work productively and ensure good results. The organizational and planning skills I gained in the service still serve me well today. I’m not saying that I succeed every time—far from it, but I have learned to keep trying until I find a way to succeed.

My service was quite some time ago, so I can’t speak to the training that the military receives today with any authority. However, judging from the content of the slideshow, I’d say that the military still values the kinds of things that helped me become the sort of person I did after I left the service. Things like learning to see what is important in a list of to do items, and what isn’t, is part of the military way of doing things. You never have enough time to complete a to do list in the service—prioritizing is a must.

The main reason I’m writing this post today is to support my fellow veterans. When you hire a vet, you’re getting someone with a broad range of experiences that you simply can’t get outside of the military. You get someone who had the drive to complete tasks under fire and will certainly have the same drive to complete tasks for your organization.
