Considering the Human Face of 3D Printing

A lot of my posts discuss the technical side of issues such as 3D printing. They’re a clinical treatment of a technical topic—devoid of sentimentality. Of course, this is a natural outcome of the kind of writing that I do. Most of my books contain accessibility aids in them because I strongly believe in the power of the computer to level the playing field for those who need a little extra help to be productive. Some of the things I’ve seen during my career have just amazed me and I’m sure that I’d be even more amazed were I to see it all. However, the technology I present is often faceless and lacks that human touch that really is needed to convince people about the validity of using technology to make life easier for those around us. That’s why a recent Parade article, How 3-D Printing is Transforming Everything from Medicine to Manufacturing, struck such a chord with me.

No longer is the technology faceless. You hear about how 3D printing has helped a real little girl live a normal life. The look on Anastasia Rivas’ face tells the whole story. It’s the same look that I’ve seen before when people’s lives are transformed by accessible technologies and it’s the same look that continues to drive me to cover accessibility in every book I write, in every way I possibly can. For me, technology isn’t about games or productivity software; it’s about making a difference in people’s lives—helping them do more with every asset they have. It’s the reason that I’d love to see fully secure, ultimately reliable, and easy to use software sometime in my lifetime, even though such a goal seems absurdly unrealistic today.

The point of this post is that the software you develop has real implications for real people. There is a tendency by developers to view software as an abstraction—as something that simply exists. In fact, there is a tendency to view software simply as a means to an end, but software and the hardware it runs on is so much more. I usually leave out the specific “who” part of an article to help you better concentrate on the technology you’re using. However, after seeing the Parade article, I just had to say something about a specific person affected by the technology that we all use and create as developers.

When you write software, make sure you consider the specific “who” of that software. Specifically who will use the application and what are the needs of that specific person? It’s a question we all need to answer despite the tendency to view software in the abstract. Let me know your thoughts about the human face of technology at [email protected].

 

Death by Connected Device

The title for this post is dramatic on purpose. In my book, Accessibility for Everybody: Understanding the Section 508 Accessibility Requirements, I describe all sorts of useful technologies for making the lives of those with special needs better. In fact, this particular book has received so much attention that I’ve expanded its coverage significantly by devoting forty (and counting) posts to it. The fact is that implanted devices will continue to be a part of our lives and their use will only increase, which is why articles, such as Cyber crime: First online murder will happen by end of year, warns US firm, have me more than a little concerned. The fact is that we’re all in line for a major wake-up call at some point if something isn’t done to secure the Supervisory Control and Data Acquisition (SCADA) systems we all rely on to connect devices to the Internet today. The hardware, software, and other functionality required to make everything happen is encapsulated in a technology known as the Internet of Things (IoT). Soon, everyone will know about IoT, but few people will know or understand the underlying SCADA systems that goes with it.

The part of the articles that I’ve read so far that intrigues me most is that politicians and others in the know have been disconnecting themselves from the Internet. Note the mention of Dick Chaney disconnecting himself from the wireless part of his implanted device in the aforementioned article. If the devices and their connections were secured, our former vice president wouldn’t be quite so worried. Unfortunately, the rest of us probably won’t be quite so lucky unless we refuse to have the devices implanted at all (which would seem to be a self-defeating stance to take). I’ve actually been discussing this issue for quite some time now. The latest significant treatment of the topic appears in my An Update On Special Needs Device Hacking post. I’ve also broached the topic in Determining When Technology Hurts. The point is that this issue isn’t new, but we certainly haven’t done anything about it.

Will it actually require a slew of front page news stories depicting people assassinated through their implanted devices for someone to get the idea that there are really awful people out there who would like to kill someone (anyone) with impunity? It seems to be the case. So, now we’re seeing stories about the event actually taking place sometime soon. Even if we don’t see someone killed, I can see a situation where people have money extorted from them by hackers who have gained illegal access to their implanted devices.

I’m all for the advancement of technology that has significant potential to help people. I’ve written more than a few posts on the topic. Helping people to walk, see, hear, touch, and have generally better lives is a great idea in my book. However, the time is long past for securing these devices in a meaningful way so that only those who really need access will actually get it. Just why there hasn’t been any legislation regarding this need is beyond me. Our politicians are obviously aware of the problem and have done the work required to protect themselves, but they don’t see to be in much of a hurry to protect their constituents.

Given what I’ve seen in the past, I’m sure the medical community won’t be in any hurry to secure these devices because security has been a legislated requirement in the past. With this in mind, what do you feel needs to happen with these devices to make them a better deal for those who need them? Let me know your thoughts about the lack of security for implanted devices and devices connected to IoT in general at [email protected].

 

A Question of Balancing Robot Technologies

The question of just how robots will affect us in the future consumes quite a bit of my time because I’m so interested in how they can be used for good. For example, robots are currently used to fight fires and to keep humans out of inhospitable environments. We also rely on robots to build some of the goods we enjoy and as a result, there are fewer assembly line accidents today than there were in the past (the quality of the output is also increasing). In the future, you can count on robot technology to help you remain independent, rather than ending up in a nursing home. There are even cars that rely on robots to drive them today and if things turn out as I expect, everyone will eventually use this sort of vehicle because robots will actually follow the traffic laws and reduce accidents as a result. In fact, it’s not too surprising to think that robots will appear in a lot of different situations that you don’t see them in today.

Humans are afraid of change. So, I’m also not surprised to find reports online that range from robots stealing jobs to terminator type robots killing us all off in order to save us (as in I, Robot). The fact is that robots really are under our control and as long as we exercise even a modicum of judgement, things will remain that way. I’m not saying that we couldn’t create a terminator-style robot. Recent advances in chip technology make it quite possible that we could create such a robot, but it’s important to ask why we’d ever do such a thing. In order for a new robot to become successful, there has to be a commercial reason to develop it and no one is interested in creating a terminator to destroy the human race.

What I think is more likely to happen is that robots will become companions to humans—devices that are both willing and able to take the risk out of human existence. The reduction of risk is an essential element in the robot/human relationship. We’ll continue to increase our use of robots as long as we can see a significant benefit to our personal lives. For example, it would be nice if we could eliminate the use of nursing homes altogether—that people could continue to live in their homes using robotic assistance. And, because those robots would be dedicated to the humans they serve, the standard of caregiving would increase dramatically. Of course, we have to get used to the idea of talking to a mechanical contrivance. Wait, we already do that—just consider how people interact with applications like Apple’s Siri.

Of course, people are asking what humans will do in the future if robots take on all of the tasks we have them slated for. For better or worse, the human condition has been changing at an ever more rapid pace over the last several years. If you look at just one statistic, you’ll miss what I’m trying to say here. For example, humans now live to an average age of 80 in many areas of the world—the average age will only increase barring some major change. People have children later in life now and focus more on career during the early years. Schools focus on getting kids to college and the college courses are becoming more challenging. In short, the environment in which we live today will change significantly in the next 40 or 50 years—to the point that most people won’t recognize the future as being any part of the past.

The change that has grabbed my attention most though is how much technology is now incorporated into humans (and the pace is only increasing). Yes, most of the technology currently does things like help people walk—it meets accessibility requirements. However, it’s only a matter of time before the technology will be used to help extend life and potentially make humans better adapted at excelling at tasks that we can’t even imagine now. So the question isn’t one of robots stealing jobs or killing us off terminator style, it’s one of understanding that humans are changing is a significant way and we’ll actually need robots to excel in the future.

Comments and CAPTCHA

In my Using CAPTCHA for Comments post, I described the need to use CAPTCHA to help keep spam under control. Using CAPTCHA has dramatically reduced the amount of spam the blog is receiving and provides a nicer environment everyone. In a perfect world, I wouldn’t need CAPTCHA, but the spammers have other ideas. So, this is one of those situations where everyone has to pay for the misdeeds of the few and I truly am sorry I had to implement this solution.

Of course, anti-spam solutions are only good if they actually do the job. This solution does keep the spam under control and many readers have written to tell me that it works better than the CAPTCHA solutions used on other sites. I want things to be easy and workable for everyone. This solution also seems to be doing a better job of keeping the spammers at bay than other solutions I’ve tried, so it’s both easy and effective—a rare combination.

A reader mentioned yesterday that he couldn’t get the CAPTCHA I selected for the site to work. The CAPTCHA solution doesn’t want to accept the input he’s providing. What I’m trying to do at the moment is track down what is happening because I want everyone to be able to post comments as needed. If you’re having problems using the CAPTCHA on this blog, please let me know at [email protected].

Please provide specifics on what you’re seeing to make it easier for me to hunt the problem down. If you could also let me know which OS and browser you’re using, that would be helpful. I need as much information as possible to determine whether I can fix the problem or whether I have to work with the CAPTCHA provider to fix it. I’m hoping the problem is limited to a few people and that there will be an easy fix, but I need good information to make this determination. Thanks, as always, for your help!

 

An Issue with Cloud Computing

The world is heading toward cloud computing at a frantic pace. However, the question is whether cloud computing is ready for the world to rely on it. I keep hearing about major outages of line of business applications. This is not good. Businesses need to be able to rely on these applications in order to complete their daily operations. However, when they aren’t functioning properly, it can cause big problems for the business. Of course, some businesses do reach out to IT companies in Melbourne, or somewhere closer to their office, for help with these sorts of problems. That usually helps businesses to continue working with few problems, ensuring that they can get their work done. However, for businesses without IT support, this can cause huge issues. For example, Visual Studio Online recently suffered a major outage. If you’re a developer, the last thing you want to hear is that you can’t access the application you use to create new applications. Just think about the implications about such a scenario for a while and all kinds of negative images come to mind.

What really gets to me is that Microsoft did manage to get Visual Studio Online fixed in about five hours and it identified a potential source for the problem, but it still doesn’t know the cause. Not knowing the cause means that the problem can easily happen again. The loss of income to companies that rely on Visual Studio Online could be huge.

However, the basic problems with cloud computing aren’t just limited to application availability. The biggest problem is saving data to the cloud in the first place. Application development is tricky at best. You absolutely don’t want to give your trade secrets away to other companies and losing data is too terrible to even consider. There is also the connection to consider-whether your users will be slowed down by inefficient communications. Cloud-based applications can also change at a moment’s notice and it’s even possible that a company could simply orphan the product, making it completely unavailable. Losing access to your application in the middle of a development cycle would mean starting from scratch-can your organization really afford it?
Don’t get me wrong. Online computing has a lot of advantages and there are times when using a cloud application works just fine. In fact, I use a cloud application to write my blog each week. However, I also save a copy of the posts to local storage because I simply don’t trust anyone else to make my backups for me. One of my non-business e-mails is also a cloud application. I don’t make a copy of the data in this case because losing it wouldn’t cause any hardship. The point is that I think through the ramifications of using cloud computing carefully and make informed choices-something every organization needs to do.

sd-wan to disconnect from my network. Your business simply has too much riding on the applications you use to have to worry about whether the application will even be available then next time you need it.

I’m sure that some people will write to let me know that their cloud application has never failed tns-serif; font-size: 14px;”>Will cloud computing ever be ready for prime time? I’ve had a number of readers ask that question. I’m sure that cloud computing will continue to improve. There may come a time when you can trust it hem, to which I would add, “yet”. Desktop applications fail too, but with a desktop application, you’re in control. You have a copy of the software locally and you don’t have to worry about the software becoming unavailable or being changed at precisely the wrong time (adding code breaking functionality).

Communication of All Kinds for Fun and Profit

A number of readers have taken pokes at me for my recent Writing Letters post. Interestingly enough, since the time I wrote that post, I’ve picked up another pen pal. The post, in case you haven’t read it yet, makes the point that most forms of communication have a purpose, or are at least a bit fun to employ. As long as I have correspondents, I’ll continue to write them letters. It’s something I look forward to doing now each Thursday night. There is something quite nice about receiving letters in the mail and I don’t relish ever giving it up. Having pen pals can be a lot of fun! As long as you get the address right and the name, you’ll know where it is going and who it’s going to, for example, if you are writing to someone in Argentina you can use https://www.codigopostal.ar/ to find the zip code you need to get it correctly delivered.

It was while I was reading some reader e-mails that I came across another form of communication in the ComputerWorld article entitled, “Telegram not dead STOP Alive, evolving in Japan STOP.” Interestingly enough, in the country where the telegram was first sent, Western Union stopped sending telegrams in 2013. The final telegram was sent on July 14th. Perhaps someone should mention to Western Union that the Japanese have a thriving telegram business and suggest we follow their model. It’s hard to see someone else take over a technology that we created through innovation and hard work.

The point is that there is something to be said for older forms of communication, even those that aren’t particularly practical today. Although I can make a strong case for writing letters, the arguments for continuing to use telegrams, except for the pure pleasure of sending one, are a bit weaker. Even so, it’s interesting that the Japanese have continued to make them work. The difference seems to be one of desire and, of course, innovation.

My one, and only, telegram turned out to be of the singing variety. Fortunately, the fellow who delivered it had a pleasant voice. You can still find places that will deliver a singing telegram for you, complete with the tchotchke of your choice (mine came with balloons and a letter from my wife, telling me she loved me). As a high speed form of communication, the telegram’s days are done. We have all sorts of other ways to accomplish the task now. However, getting a telegram could still be viewed as quite special.

There are many other interesting forms of communication. I’ve never had anyone hire a skywriter for me, but you can still find them online as well. I imagine more than one fellow has relied on skywriting to propose; although, it never occurred to me to try it. Nothing quite attracts your attention though like a message written in a clear blue sky-assuming that the weather is accommodating.

As an author of technical books, I spend a great deal of time looking at communication in all its forms: verbal, aural, visual, and other forms. I once spent a month researching the tactile vocoder-a device that allows its wearer to hear through the skin using vibration. Imagine that you’re deaf and the tactile vocoder makes it possible for you to hear again, even if you don’t have actual ears. So, it’s not too unusual for me to look at communication both old and new to see how it’s being used today and whether it might not be employed in some other manner. So, yes, I still write letters and I’m still rooting for the telegram, but I’ve also looked into odd devices that help people communicate in amazing ways. Communication, in all its amazing forms, is something you do from the day you’re born until the day you die. Let me know about your view of communication at [email protected].

 

Welcome to Labor Day

It’s my sincere hope, if you’re an American, is that you’re reading this post on Tuesday and that you’re not stuck in front of a monitor on a perfectly beautiful Monday. Labor Day is literally a day for celebrating the contributions of the labor force to the wonderful standard of living we now enjoy. Originally it was meant to highlight the hard work produced by people in less than ideal conditions. I’ve explored some of this information in two previous posts: Labor Day, Time for Fun and Reflection and Labor Day, Eh?. (My Celebrating Labor Day post was simply to let you know I’d be offline.)

I did come up with a few interesting facts about Labor Day this year. For example, I discovered that it’s traditional for men to wear a straw hat from Memorial Day to Labor Day, and then a felt hat the rest of the year. In fact, there is a cowboy etiquette site that will steer you straight on all the rules. Of course, most men don’t wear hats any longer and my hat would break any tradition because it’s made from cloth. As with the rule that women can’t wear white after Labor Day, the hat rule has faded into obscurity (even more so because I could find few references to it).

A number of other nationalities celebrate Labor Day, which I found interesting. For example, if you speak Spanish, Labor Day is called “Día del Trabajo”. However, in Mexico, people actually celebrate May Day (Primero de Mayo) as Labor Day. Over the years I’ve become more interested in how people in other countries celebrate holidays that are close to or the same as our own. The fact is that Americans used to celebrate Labor Day in May as well. After the 4 May 1886 Haymarket Riot, American’s celebrated May Day as we celebrate Labor Day now. The 10 May 1894 Pullman Strike convinced President Grover Cleveland and Congress that a different holiday was needed, which is how we ended up with Labor Day. Interestingly enough, Canada celebrates Labor Day on the same day that we do.

Today is a day celebrated with family time, picnics, the last outing somewhere, or possibly just a barbecue. No matter how you celebrate, make sure you take time to consider the reason for the celebration. Somewhere, perhaps not even in this country, someone is working in a factory in less than ideal conditions to provide the goods that you use on a daily basis. Yes, they’re getting paid (hopefully), but factory work is usually hard and not appreciated by those who have other tasks to perform in life. Today is the day to give these people their due. Let me know your thoughts about Labor Day at [email protected].

 

Using CAPTCHA for Comments

It’s an unfortunate sort of thing, but the one percent who cause problems often dictate the restrictions on the ninety-nine percent who don’t. I had hoped when I moved to my new blog software that I might be able to get by without using a tool to ensure someone commenting actually is a human. People had complained about the previous version of my Completely Automated Public Turing Test To Tell Computers and Humans Apart (CAPTCHA) software. It was hard to see at times, even harder to work with. The bad news is that you’ll be dealing with CAPTCHA again on this blog whenever you make a comment. Several hundred spam posts every day make it clear that I really can’t avoid it, much as I might like to do so.

Now for the good news. Unlike the old blog software, I have access a whole host of CAPTCHA solutions when working with the new blog software. I’ve come up with what I hope is a less difficult means of keeping the spammers at bay. No, I won’t thwart all of them, but I’m determined to come up with a solution that makes life easier for the majority and a whole lot harder for the minority. Perhaps they’ll get the idea and go bother someone else for a while.

I do want your feedback. Does this new CAPTCHA solution seem to work for you? If so, please leave a comment to this particular post. This is one situation where I’d prefer you not contact me through e-mail. I want people to try the comment system and let me know how they feel about it. Thanks, as always, for your support of my blog.

 

Bletchley Park Reborn and a Social Issue Revisited

You may not have ever heard about Bletchley Park. In fact, the place was one of the best kept secrets of World War II (WWII) until just recently. Of course, like many secret places, this one fell into disuse after the war and nearly ended up in the scrap heap, but a restoration effort has been under way for quite some time now. As a computer scientist, the entire Bletchley Park project interests me because it was the first time that many computer principles were put into play. The project relied on cutting edge technology to reduce the length of the war and saved thousands of lives. A lot of other people must feel as I do because the park recently had its 100,000 visitor.

This particular historical place is receiving a lot of notice as of late. For example, there is a PBS television show called The Bletchley Circle that talks about what happened to some of the ladies who worked there after the war. The show makes good viewing and the feelings and situations presented are realistic to a point. I doubt very much that any of the people who actually worked there ended up as amateur sleuths, but it’s fun to think about anyway. The show does have the full cooperation of the restoration group and is even filmed there.

The computer systems used at Bletchley Park were immense and even the lowliest smartphone today probably has more processing power. However, WWII was the first war where computer systems played a major role and reading about their history gives insight into the directions that the technology may take in the future. The most important factor for me has been that the group working at Bletchley Park was made up of the finest minds available, regardless of gender, sex orientation, religion, age, or any other factor you can imagine. The only thing that mattered was whether you had a good mind. It’s how things should be today, could be today, but aren’t. It’s not hard to imagine the impact on the problem of global warming if we had such a group now.

All good things must apparently come to an end. At the end of the war, the group that performed so many amazing tasks was broken up, rather than being retained to work on other problems, such as reconstruction. The sheer waste of not keeping these minds working together on other problems staggers me, but it has happened more than a few times throughout history, and all over the world. No country in the world is exempt from such terrible waste. The women in the group ended up going home to be housewives and pretend that nothing ever happened. It’s the reason that The Bletchley Circle strikes such a chord with me. The show presents a kind of “what if” scenario.

If the world is to survive, it’s important that we think about the incredible waste of not using all the resources at hand for solving problems (and there are more than a few problems to solve). If this group serves as nothing else, it’s a reminder of how a few extremely talented people were able to solve a seemingly insurmountable problem. They should serve as an example today for all those who think the world’s problems can’t be solved—they resonate as a beacon of hope. Let me know your thoughts about Bletchley Park and The Bletchley Circle at [email protected].

 

Writing Letters

It seems outdated, old fashioned, archaic, and all the other superlatives you can attach to it—writing letters, by hand, and then mailing them sees like something that no one does anymore. Contrary to common belief, letter writing isn’t completely dead in this electronic world of instant communication using text messages. I’ve been writing regularly to five people. Yes, I actually get out writing materials, write the letter by hand, and then put it in the mail. Of course, the question is why I’d do something so insane in this modern world. People I tell about my letter writing ask what I might possibly hope to achieve by doing so. In fact, some might even doubt my sanity.

There is something to be said for taking time to properly compose a letter. The physical effort required to write one, tends to make the value of each word more. A well-written letter is a joy to send and receive. Taking the time to pick and choose each word, to consider what really is necessary to say, makes a written letter different from e-mail or a text message. As the value of each word drops, so does the quality of the content. It’s something that has struck a chord in me as I’ve read the written missives and compared them to some of the e-mails I receive. Not every written letter is a good one and not every e-mail is poorly written, but generally, the written letters contain carefully selected, well-written material.

However, quality of content aside, there is something special about receiving a letter in the mail. There is the anticipation of sending one and the anticipation of receiving a response. Each trip to the mailbox is no longer a boring collection of bills and junk, but a contemplation of something that is truly wanted. It adds excitement to my day. As I’m getting older, I find that instant gratification lacks excitement, anticipation, and pizzazz. In order to be worthwhile, anticipation needs time to grow and mature. Hand written letters bring something back that has been lost, a kind of hope that is missing from modern society.

Even more important, a written letter stimulates the senses in ways that an e-mail can’t. I opened a box of letters the other day from my wife. She wrote them while I was in the service and I could still smell her perfume on some of them. You can’t perfume an e-mail. Her fine writing reminded me of her unique way of approaching life—the letters were both dainty and artistic. They had a flow that reflected her way of viewing life. E-mail lacks any of that sort of feel. The paper itself varied from letter-to-letter. Some of it was quite fancy; other pieces contained interesting pictures. However, each letter was unique in its own way, making the experience of reading it unique as well. All these ways of transmitting information are lost in the instant gratification of e-mail and many younger people will never experience the joy of opening a mailbox and finding a letter, a unique transmission of thought from one person to another.

One of the main arguments I hear against writing letters is the cost of doing so. After all, postage is incredibly high. I started thinking about that the other day and it doesn’t wash. Consider the cost of your Internet connection. Even an inexpensive plan would pay for quite a number of letters each month. Given the plan I have (a low cost 1 Mb/s DSL connection), I could write 40 letters every month and still not exceed what I’m paying for Internet. Actually, the mail service is still a bargain when you think about it.

This morning I also listened to a radio program that talked about the importance of the hand written letter in understanding the past. Some historians spend considerable time reading letters and drawing information out of them that probably isn’t available in an e-mail. Of course, most people erase their e-mails soon after they’re received, so there won’t be much in the way of historical data for historians in the future to use. E-mail tends to be temporary—letters can last for hundreds of years (and many do).

Of course, social media, texting, e-mails, and the Internet all have a purpose to fulfill. There are times when quick communication with a large number of people really is necessary. However, there is still a place for the more personal communication provided by hand written letters. Take time to write a letter to someone you care about today.
