All Cooped Up

I normally let my chickens run free during the entire year. They get outside and play games outside while pecking around for things to eat. They really are quite funny at times. One of their favorite winter games is Queen of the Hill. I put a french fry or other treat on top of a snow hill and the chickens race to see how gets it first. The chickens knock each other off the hill and grab the french fry until it’s gone. Of course, the game continues as long as I have french fries to offer them. The outside time is important because it allows the chickens to exercise properly and to gain access to alternative food sources, such as bugs. In addition, getting out of the coop provides them with fresh air and time to interact with their environment.

After seeing my egg production (and subsequent sales) drop to nearly nothing this past winter, I decided to try something out. On truly cold days, I’ve been keeping the chickens in the coop. I’m not talking about a coop with the door open, but with the door closed so that the coop stays significantly warmer. On the coldest days, I’ve been putting a pot of hot water in the coop to partially heat it. As a result of this change, my chickens are laying more eggs—a lot more eggs. In fact, egg production has increased threefold over egg production last winter at this time. Mind you, I’m getting this increase without disturbing the chicken’s natural light cycle by using a heat lamp or other light source.

The results seem consistent. In addition, the only thing I’ve changed is the time the chickens spend in their coop. I did note that there is no increase after a certain point. Keeping the chickens in their coop six days a week didn’t provide an appreciable increase in production over four days. What seems to be the most important factor is choosing days that are especially cold. Right now I’m keeping the chickens in their coop when the temperature falls below 20. However, I plan to keep playing with the temperature to see what effects I can come up with. The chickens might actually do better if I keep them in the coop anytime it’s below freezing, but something tells me that they’ll begin fighting if I do.

What I’m trying to figure out now is how cold is too cold for the chickens. They survive just fine, even if I let them out in relatively cold weather. The thing that changes is the number of eggs they lay. The cold stresses the chickens just enough to stop laying almost completely. I’m still experimenting to find the trigger temperature for this effect. Figuring out the correct temperature is important because the chickens really do need the outside time to remain healthy.

Like many topics related to chickens, trying to find specific temperature guidelines online has proven impossible. However, there must be others who have experimented in figuring out just the right temperatures for letting chickens go outside to play.

Considering Our Future Cyber War

It’s not if a cyber war will happen, but when. Precisely what form such a war will take depends on the perpetrators and their goals. I’ve spend quite of time discussing the relative insecurity of the Supervisory Control and Data Acquisition (SCADA) systems out there. However, I’m only assuming that SCADA is going to be targeted at some point because it’s such low hanging fruit and no one seems to have any interest at all in securing. Plus, the attack would be of the sort that we’d have a hard time defending against (and possibly identifying at first as the hospitals fill with victims of some mysterious problem).

I recently read an article by John Dvorak entitled, “What if Facebook Is Hacked Next?” John makes some excellent points, but probably doesn’t go far enough. Why would an attacker stop with just Facebook? Why not attack all of the sources of social media out there, including places like LinkedIn and Twitter? The confusion created by the loss of all social media would be amazing. It could easily act as a smokescreen for some other activity even more devastating than the loss of data. While everyone is scrambling to fix their social media issues, someone could work in the background to do something truly horrible.

Actually, the attacker might not even have to do anything other than disrupt all online activities. Think about the number of jobs lost, the hit to online commerce, and the other problems that such an attack would cause. Perhaps these people are simply waiting until more brick and mortar stores close that people no longer have local resources to help in such an emergency. For example, think about the problems that the loss of online stores would have to IT professionals who maintain huge networks of computer systems. The potential for truly terrifying results is amazing.

A cyber war is coming. Just when it will arrive is the topic of much speculation, but my feeling is that it’ll come sometime soon. What sorts of security measures do you have in place? Have you done anything else to prepare? Let me know about your thoughts on cyber war at [email protected].

 

Radio Shack, We Knew Thee Well

I’m dating myself here, but the first time I entered a Radio Shack was in 1972. I had just finished reading The Radio Amateur’s Handbook and was absolutely fascinated by the whole thought of working with electronics. The combination of reading science fiction and electronics books of various sorts, convinced me to go to a technical high school. I graduated with all the necessary knowledge to become an apprentice electrician. However, entering the Navy moved me into computers, where I remain today. (I started out as a hardware guy and moved into programming later.) Radio Shack was filled with all sorts of cool looking gizmos. It was akin to entering my science fiction books and experiencing what “could be” first hand. The day I finished designing and building my first power supply and amplifier was an absolute thrill. I still have the plans for it somewhere. The mono output of 20 watts seemed fantastic. I’m not the only one with fond memories-authors such as PC Magazine’s Jamie Lendino and John Dvorak have them as well.

Over the years I watched Radio Shack change from this absolutely fascinating place I had to visit every time I passed it to something less. Eventually, it became just a common store-the aisles filled with televisions, radios, and consumer gizmos of all sorts. It got to the point where I could buy the same type of goods just about anywhere for a much lower price. For me, the death spiral was just sad to watch. As a country, we really need stores that encourage people to invent-to think outside the box. Unfortunately, Radio Shack is no longer that store. I visited a Radio Shack in a mall the other day and there were only a few items left for sale at high discount. I helped a friend buy a mouse. It was an odd feeling to leave the store one last time knowing that I’d never see the store I knew and loved in the 70s and 80s again.

Even the salespeople changed over time. During the early 70s when I first started going to Radio Shack, I could hear salespeople talking the talk with any customer that came in. One of them even convinced me to use a different transistor for my amplifier and to rely on a full bridge rectifier to make the output cleaner. If these terms seem foreign, they do, in fact, belong to a different time. The surge of creativity I experienced during that phase in my life is gone-replaced by something totally different today. The young lad I talked with the other day was a salesperson and just barely knew his trade. Gone are the salespeople who really made Radio Shack special.

I yearn for the resurgence of creativity and of stores that promote it. This is one case where brick and mortar stores have a definite advantage over their online cousins. When you go into a brick and mortar store, you can talk with real people, see real demonstrations, touch real hardware, and get that special ethereal feeling of entering the zone of the tinkerer and the definer of dreams. Radio Shack, we knew thee well, and we really need something like you back.

 

The Art of Observation and Writing

People watching is a favorite activity of mine. No, I don’t sit at the bench at the mall and make snide remarks about people’s attire. I’m also not too interested in the exceptions to the rule—someone doing something so absurd that it falls well outside the range of normal human activity. (Although, I must admit that the guy who ended up in a fountain because he wasn’t looking as he was texting, was sort of funny.) No, I’m more interested in how normal people react in normal ways to normal situations. Observation is a key tool for any author because seeing how people act and react is an essential part of communicating thoughts and ideas to them. I can’t see my reader during the reading of one of my books, so observation helps inform me outside of that environment.

On one particular day, I was watching a young couple argue. The precise reason for the argument isn’t known to me and it’s immaterial anyway. The two of them argued for quite some time, each insisting the other wasn’t listening. Both went off in a huff. I’ve always hoped that they made up. The things that struck me was that the two people communicated differently. The wife’s communication was both vocal and emotional. However, it was her body language that said the most. The husband was stiff as a board and you could tell that he had built defenses against any encroaching information that might conflict with his preconceived ideas of how the communication should go. However, he did use his hands quite a lot and did make really good eye contact. His choice of words was the key ingredient in his communication. Two people, communicating two completely different ways, and neither of them hearing the other.

Books are like that sometimes. I get e-mail from my readers that makes it obvious that I didn’t choose the correct manner of communication. Yes, the information they’re requesting is most definitely in the book, but they didn’t see it because the information didn’t appear in a form that attracted attention. In some cases, the reader did see the information, but couldn’t understand it. In a worst case scenario, the reader saw the information, read it, thought it was understandable, and then didn’t apply it correctly. In many cases, I find that the reader really didn’t understand the information after all.

Another couple, on another day, showed me something else. Nuance is often part of communication. The precise formulation of interaction is important. In this case, the husband was following his wife shopping, but I could tell that his interest lay in his wife, not in what she was buying. She picked a particular item up, looked it over, and put it on the shelf. A little while later, they came back. She picked up the same item, looked at it intently, and then put it back on the self. I was surprised to see the man come back sometime later. He bought the item and almost passed me by while wearing a magnificent grin. When asked what was up, he explained that by observing his wife, he found the perfect gift for her—something she really wanted, but didn’t buy because it was too expensive.

The communication between author and reader is often nuanced in ways that defy simple explanations. Yet, when they’re understood, they seem absurdly simple. It’s the reason I employ beta readers, ask questions on this blog, and maintain statistics for my books. All of these observation techniques tell me how you’d like to receive information from me without my having to ask the question directly. I can provide you with the perfect presentation without saying anything at all.

How do you employ the art of observation? Do you find that it provides an effective means of communicating thoughts that might not receive proper treatment when spoken. Send your ideas on the topic to [email protected].

 

Wood Stove Cleaning Day

It’s February and the wood stove has seen a lot of use this season. It’s easy to forget that the wood stove needs maintenance while you use it. I discussed annual and regular maintenance of a wood stove in my Care and Feeding of a Wood Stove post. However, a wood stove requires more maintenance to continue to work properly. A reader was asking me the other day just how much maintenance I recommend and that’s a really hard question to answer. It depends on how much you use your wood stove and what sort of wood you burn in it. You also need to consider the wood stove type and its age.

I actually do maintenance twice weekly during the heaviest usage portion of the season. During the twice weekly cleanup, I make sure the wood stove is completely out and empty the ashes. The ashes actually work quite well when spread on icy areas. The grit in the ash keeps you from slipping. It’s a bad idea to put the ashes where they could cause a fire, such as your compost heap, unless you’re absolutely certain that they’re out. Even then, you must exercise extreme care.

As part of my maintenance, I sweep down the outside of the wood stove using a foxtail broom. This includes the stove pipe and any other surfaces that could become encrusted with dirt, dust, or cobwebs. Not only does such cleaning enhance the appearance of your stove, but it can also help (slightly) with its efficiency and potentially reduce any fire hazard.

Cleaning any glass on the front doors is helpful. You can’t manage the fire as well if you can’t see it. I’ve tried a number of cleaners. Mr. Clean is my current choice. It seems to do a better job with the buildup on the glass. I know some people use the stuff to clean other glass around their homes, like the frameless shower doors in their bathrooms for instance. If someone else comes up with a good selection, please let me know (but please try Mr. Clean first for comparison purposes).

Chimney fires are something to avoid at all costs. Burning hardwoods that are completely dry help quite a lot. A little creosote can still build up through and you really do want to get rid of it. All the chimney sweep should find in your chimney is a little ash. To help keep things clean, I spray Anti-Creo-Soot into the stove once a week. Make sure you follow the instructions on the bottle precisely. If you don’t, you might find yourself dealing with an uncontrollable fire that could cost you a lot more than your home. If the fire doesn’t get that far, you may still have to deal with fire damage, requiring the aid of a fire restoration service similar to Service Master by Zaba (https://www.servicemasterbyzaba.com/fire-restoration) that may be able to help you with fire damage repair.

Keeping things clean will help you enjoy your wood stove longer and to use it safely. A few minutes spent cleaning your wood stove may save you a lot of grief later. Let me know about your cleaning tips at [email protected].

Our Borders are Porous

No, I’m not talking physical borders here—I’m talking cyber borders. I’ve talked a number of times about the relative insecurity of Supervisory Control and Data Acquisition (SCADA) systems. My biggest personal concern is how leaks in these systems can affect people with special needs. At a minimum, implanted devices used by people today are open to hacking. However, there are some reports that say that hackers could eventually become murderers. I wrote Accessibility for Everybody: Understanding the Section 508 Accessibility Requirements with the idea that implanted devices and other aids should help people, not hurt them.

However, other sorts of devices are leaky. Just about any hacker could attack our water supply, power grid, or any other utility. A hacker could turn off your car engine by remote control, lock you into the car, and then do whatever nefarious deed seemed pleasant at the time. These posts aren’t meant to scare you as much as to inform you that the borders of your devices are wide open to attack in many cases. Yet, despite a huge number of newspaper articles, radio talk shows, government inquiries, and odd assorted other do nothing activities, surprisingly little has been done to secure anything.

It probably won’t surprise you to know that the latest casualty, in a long list of problematic devices, is the gas pump. Yep, your gas pump can turn against you. I hadn’t really thought about a gas pump as being anything particularly worthwhile to hack. Yes, you could possibly turn on the pump and get free gas or deny someone else their gas, but it really didn’t strike me as something that hackers would invest time in learning about. Actually, it turns out that gas pumps are connected to all sorts of monitors and messing with the pump can cause those monitors to go off. It doesn’t seem like alarms are anything to worry about either, but think about someone intent on disrupting the emergency services network in a city so that they can attack in some other way. While everyone is distracted with the gas pump spills that haven’t actually happened, someone could do something that would cause the city to go into overload because emergency services are already overwhelmed.

The thing that gets me about a lot of these deficiencies is that they aren’t caused by systems that are secured, but someone has manged to get into anyway. They’re caused by systems that have no security at all. That’s right—someone connected those gas pumps to the Internet so they could monitor them remotely and didn’t add any security at all. Someone who knows the right information can just walk right in and cause all sorts of mischief.

From direct attacks on our infrastructure, to feints used for distraction, to personal attacks, SCADA systems will let us down at some point. I’m surprised that we haven’t had a major issue so far. Perhaps someone is out there right now planning just the right sort of attack that’s designed to cause a maximum of damage. Until we make security a priority, these open systems will continue to pose a serious risk to everyone, whether you have special needs or not.
