In this video, I talk about a smart high efficiency DIY home heating solution that can help reduce or eliminate your heating bill. This heater is Internet connected, remotely accessible, and uses very little power – resulting in reduced heating expenses.
On Monday, 30 October 2017, I was interviewed by local ABC News affiliate KCRG for a segment on computer security and keyloggers. The video is below. Read the full story on the KCRG website.
I’m often asked by people: “What camera should I buy?” or “What’s the best camera?”
The answer really depends on what kind of photos a person typically takes. Even if you get the ‘right camera’ you may need several lenses to cover all the possible scenarios.
Below I describe a few cameras that I use and which cameras seem to work well for certain kinds of photography.
Types of Photography
My own photography spans a variety of typical subjects including architecture, wildlife, flowers, landscapes, and occasional portraits. I use the photos frequently in graphic design applications and websites. For any photos that I plan to print in large formats, I would want to use a full-frame camera if possible.
I currently use three cameras. Most regularly is my iPhone 7 Plus since I have that with me daily. The Sony DSC-HX50V is small enough that I can keep it in my carry bag. My Canon T2i is what I use on vacations or intentional photo outings where I have the time to take advantage of its manual settings.
Today, the role of the high-end DSLR camera is to offer high quality photos that can be enlarged or cropped without losing image quality. Full-frame cameras with telephoto lenses can capture some photos that smartphones or compact cameras generally can’t. Should you get a fancy DSLR camera? Well, one way to answer that question is to take a look at the photos on this page. None were taken with a DSLR. They were taken with a smartphone and an inexpensive point-and-shoot camera.
Because I have over 30,000 photos, I often rely on the GPS feature to quickly find photos based on their mapped location. So, GPS is an important feature for me. The Cannon doesn’t have GPS, but the Sony and iPhone do.
Photos that aren’t shared are like the tree falling in a forest with nobody to hear it fall. The iPhone is definitely the easiest camera for sharing on social media. With the other two cameras, I need to transfer the photos to my iPhone or computer first, then prep for sharing. So, that’s another benefit of the iPhone — life happens in real time and there’s nothing to ‘work on later’ in the proverbial free time that never seems to materialize.
With architecture there can sometimes be challenges getting positioned for a photo. If an adjacent building or road with busy traffic prevents you from backing up far enough, you’ll need a wide angle lens or panorama mode to get the entire photo that you want. A zoom lens may be needed if you’re wanting to focus in on a certain aspect of a building. The photo below was taken with an iPhone 6 Plus using the panorama mode because an adjacent building made it impossible to back up far enough to get the entire building in the photo. If you click on the image, you can see the full image resolution which is 9820 by 2942 pixels.
Another challenge with architectural photography is lighting. The photo below of the Cedar Rapids Public Library was taken in the evening. The iPhone 6 Plus made the correct exposure adjustments to achieve what looks like an artists rendering of the building. If you click on the image, you can see the full image resolution which is 2448 by 2448 pixels.
Below is an example where the aspect of the building being photographed was very high up, so a zoom lens was necessary to frame in the photo just right without requiring any cropping later. For this one I used the Sony DSC-HX50V. If you click on the image, you can see the full image resolution which is 5184 by 3888 pixels.
Bird and Wildlife Photography
For bird and wildlife photography, my favorite camera over the past few years has been the Sony DSC-HX50V. There are other similar cameras today. The key feature to look for is a 30X optical zoom with 60X digital capability, as well as the ability to automatically lock-in-on and track a moving subject like a small bird in a tree from 100 feet away. Good image stabilization while zoomed in is important because typically when you’re hiking, you won’t be bringing a tripod with you.
The photo below is of a bird on a picnic table bench from about 100 feet away. Notice the detail of the bird’s feathers, and the staple that’s stuck in the bench below the bird. This is exceptional resolution and quality considering the distance and that no tripod was used. If you click on the image, you can see the full image resolution which is 5184 by 3888 pixels.
Flowers and Nature Photography
Below are some examples of nature photography taken with the iPhone 6 Plus which is at present 2-year-old technology. The dandelion photo with frost was taken in morning light as was the frost on a fence post photo. For these kinds of close up macro photos of stationary objects, one doesn’t need a fancy telephoto lens, so a smartphone actually does fairly well.
When taking landscape photography, with a subject that remains in one place, and with plenty of time to setup for a shot, a DSLR camera can be helpful. However, some DSLR cameras may not have features like panorama mode which are helpful. The photo below was taken with the iPhone 7 Plus using the panorama mode. If you click on the image, you can see the full image resolution which is 3264 by 2448 pixels.
Here’s a photo taken with the iPhone 7 Plus using panorama mode to capture an entire vista of a lake. If you click on the image, you can see the full image resolution which is 11354 by 3894 pixels.
Okay, so I don’t actually do a lot of lunar photography, but this photo illustrates how the Sony DSC-HX50V combines its digital zoom capability with image stabilization to take a fairly detailed picture of the moon. Low light photos are always challenging because longer exposure times typically mean there’s a greater likelihood that you’ll move the camera and end up with a blurry image. Photos from 100 feet are challenging, but even more challenging are photos when the subject is about 238,000 miles away. The quality of this photo approaches what you’d otherwise need a telescope to see. If you click on the image, you can see the full image resolution which is 5184 by 3888 pixels.
An area of photography that’s traditionally been the domain of DSLR cameras is portrait photography. With the iPhone 7 Plus, Apple has brought DSLR-like portrait photography to the smartphone form-factor. While point-and-shoot cameras like the Sony DSC-HX50v have had portrait mode settings for years, having this capability in a smartphone, at the level of quality produced by the iPhone 7 Plus is something new. An example is below. If you click on the image, you can see the full image resolution which is 3024 by 4-4032 pixels.
“On Monday, 25 July 2016, I was interviewed by our local Fox News affiliate on the topic of email security. The report is archived below, the original is online.” ~ Greg Johnson
CEDAR RAPIDS, Iowa (CBS2/FOX28) — Hackers have already disrupted the Democratic Party after releasing many damaging emails from the Democratic National Committee. They were embarrassing for party leaders and will likely result in at least the party chair stepping down this week.
But IT security for political groups and organizations at many different levels often balances on human error.
Running a campaign is a lot like a small business. There’s plenty of things to spend money on. With so much technology all around us, it’s often not an area where campaigns spend a lot of extra resources.
Physical protection is generally something we think politicians and their Secret Service Agents get right, especially at the highest levels.
Online, IowaCityTechnologyServices.com Director Greg Johnson says even they fall short.
“There are just so many points of failure,” said Johnson.
CBS2/FOX28 spoke to local campaigns and elected officials from both major political parties about their IT security. They say, generally, campaign staff email is handled through services like Google’s Gmail and some additional security options within those programs. Rarely will even the most Congressional races have a dedicated IT team to keep it safe.
“Just using Google, or some similar service, steps it up a bit, but it’s not entirely secure,” said Johnson.
Once a candidate is elected to Congress, their staff is brought on to Federal Government systems. That’s usually a step above most security, but Greg says it still doesn’t solve human carelessness.
“All it takes is for one person to lose their computer or have one person get their password and suddenly, that person has access to all those emails that somebody was copied on, or anything they’ve ever sent or received,” said Johnson. “It would be a huge collection of emails just from one account getting breached.”
Greg says there is encryption software that would make sure emails and information is locked and can only be accessed by someone with the right password. He says that can be free, or be as expensive at $175.
As an Apple computer enthusiast, I’ve been using the Apple Mail client for years. About a year ago, I decided to switch over to using Gmail exclusively as an online email client. For my primary email accounts (included with my website hosting package), I set them to forward all emails to Gmail. I have a personal account and also a collection of other email addresses that I forwarded to a secondary Gmail address.
Here are the reasons I switched:
- Over time, the Apple Mail client became slower, and it caused my entire computer to slow down whenever it was running. I assumed this was due to the indexing of so many individual emails. I stopped seeking a solution when I learned that many people were having similar problems. Gmail was much faster than using the Apple Mail client.
- At the same time the slowness became an issue, about two years ago, there were known issues with Gmail compatibility and the Apple Mail client. Flagged and read emails weren’t synchronizing properly. For many months, people complained on the Apple discussion forums, but no solution was provided.
- In addition to these issues, I began hearing from people trying to reach me by email who were getting returned emails with an undeliverable message notification.
- I also heard from people that my emails were ending up in their spam/junk folder.
- At the time, my email inbox was limited to 1GB and constantly filling up, but Gmail offered virtually limitless email storage.
- Junk email wasn’t being identified accurately so I was having to manually sort them out.
- The Apple Mail client in iOS lacked mail rules and the intelligent Junk Mail filtering found in the native OS X desktop Mail client version. So, unless I had a desktop computer on all the time, with the Mail client running, those rules wouldn’t get applied.
- Gmail was identifying the Apple Mail client and others as non-secure email clients. So, using them required a special exception setting in my Gmail account.
So, for all these reasons, I decided to switch to Gmail.
As of January 2016, here’s why I’m switching back to using the Apple Mail client and the email accounts included with my hosting package.
- The Gmail conversation threads were problematic, and the nested messages made it sometimes hard to find where the conversation left off, especially if multiple replies were in a a thread. Messages people would send using feedback forms with the same subject line would be grouped as a conversation. Turning conversations off was an option, but not desirable either.
- Gmail would repeatedly put important emails into the Junk folder even for senders who were in my address book and even after repeatedly marking them as not junk.
- Gmail would automatically file emails into the Social, Promotions, Updates, and Forums categories, which was very helpful some of the time, but much of the time it caused important emails to be misfiled.
- Gmail lacks the ability to sort on sender, subject, date, and other aspects of messages.
- Once I setup my computer with 16GB of RAM and a solid state hard drive (SSD), the slowness issue went away. This may have also had something to do with upgrading to the latest edition of OS X (El Capitan).
- The Google Gmail client for iOS made it possible to send messages as another email. However, the Apple Mail client for iOS would not permit this with Gmail accounts. This was very frustrating. So, it was necessary to continually used the Gmail client for iOS if replying to a message and desiring the recipient to see the correct sending address.
- Clicking on an email address typically brings up the default email client on a computer. This doesn’t work with the Gmail web based system unless you’re using Google Chrome.
- The Gmail ecosystem doesn’t have the same instantaneous push feature that Apple offers with their other iCloud services.
During the transition back to my original email addresses, I’ve set an autoresponder letting people know my best contact methods — in case anyone had inadvertently received an email from those Gmail accounts.
I still maintain email accounts in Gmail, Hotmail, Outlook, Yahoo, and other services in the event there are communications issues with people using any of those third-party services. It’s sometimes more reliable to communicate with someone on the same system they are using, and other features exist that make it helpful to have an account on various services.

Having spent most of my career as a technology service and support provider, I’ve grown to appreciate others in the industry. Even if someone is your ‘competition’ you inevitably acknowledge and give them credit when they are doing things right.
At some point along the way, as a consultant you find yourself with an abundance of work to do, or you’re on vacation, or there’s someone outside of your service area, and you need to recommend a business you can trust. One such business is Erb’s Technology Solutions in Cedar Rapids, Iowa. They’ve been in business since 1961 and have many satisfied customers.
One day I had to deliver a printer for one of my clients to their facility for some in-warranty repairs. As I recall, back then, the equipment service entrance was on a lower level at the side of the building. I thought I’d take the opportunity to visit a bit with the employee working at the service desk.
The service reception desk is generally not the most glamorous job. The pay isn’t great. Usually a less experienced technician would work at the receiving and pickup area. It’s sometimes an unpleasant job if customers are upset about failed systems, crashed computers, delays in repairs, and/or unexpected repair costs.
I had a good talk with the technician that day. I let him know that I’m an area tech consultant and have been impressed with their business. He was very friendly.
When I asked his name, he told me he was Larry. Then I realized, I’d been talking to the owner of the business, Larry Erb.
At that point I just had to ask… why was he working at the service desk? Usually the owner of a successful business that size has managers who manage the managers who manage the employees.
What I learned is that he likes to have some hands on emersion in the various departments in his business. It gives him an opportunity to evaluate continuous improvement opportunities for better procedures and practices. It also lets him have direct contact with his customers and hear first hand about their experiences with his business.
Leaders are sometimes portrayed as people who are removed from the ‘commoners’ and inaccessible. It’s assumed that one of the perks of being the boss is that you don’t have to do the dirty work and heavy lifting. You’re able to escape from listening to customer complaints. Yet, these portrayals of leadership aren’t the ideal.
A true business leader isn’t trying to avoid their employees or the customers they serve. A true leader spends some time with their sleeves rolled up, working side by side with their employees and serving customers. This builds relationships and trust. It also helps an innovative leader explore opportunities for improvement — since ultimately that’s what their highest calling is.

About This Article
“In 1987, at 23 years old, I had my first experience with leadership and business management as a manager of a Radio Shack store in California. Going from a recently hired sales person, to managing my own store in 6 months was a kind of a record. In the 28 years since then, my interest in leadership and management has grown. I’m intrigued by innovative approaches to facilitating progress for organizations and businesses. Much of what I’ve learned over the years, I’ve applied to my work as President of the Small House Society (2002 to present). I describe myself as a “facilitator” in my work with the organization. I like the term facilitator because for me, that’s what a leader does — empower, equip, inspire, and help people grow in their areas of passion and expertise. So, the above article is inspired by these experiences.” ~ Greg Johnson, 12 March 2015

IOWA CITY, IA (CBS2/FOX28)– Internet hackers are still after your computers…and your identity. With some big name businesses being hacked, employers are trying to find new ways to protect themselves.
Today a technology expert tells CBS 2/FOX 28 businesses are practicing security from the inside…out.
“My husband is more into computers and I remember calling him and saying, “I clicked on this, what happened?” says Amie Villarini of Iowa City.
Most of us have gotten those emails, a convincing and seemingly legitimate message with a link that could install a harmful virus to your computer or get you one step closer to giving away your personal information. It’s called phishing. Some businesses are hiring companies to send messages like those to their own employees.
“As businesses lately have become more aware of the various threats that are out there, what people realize is that the greatest vulnerability is just the human factor,” says Gregory P. Johnson of iowacitytechnologyservices.com.
The businesses see which employees bite the bait and use the fake phishing email as a learning opportunity to increase security.
“It’s a stress test of the business to see if that business has both the physical security, digital security and that critical third component, the human training,” he says.
“Seems like a smart thing to do. I mean, if it is going to happen, might as well make sure that it happens in a way you can control,” says University of Iowa Senior Christopher Wright.
Johnson says to be careful before clicking anything. What is the address of the email? Does what they are asking make sense? Are they asking for personal information?
“That’s really the best thing you can do is go to the site you know is official and log in and then see ‘Oh, is this really happening,’” he says.
Johnson says if you receive one of these emails at work, report it to your IT department. If it happens at home, you can report it through your antivirus software. If the email claims to be from a particular institution, send it to them so they are aware of it.
If you feel your computer has been negatively impacted by one of these emails, he suggests getting it checked out by an expert. Johnson also advises regular computer check-ups.

In the past, when the culture of photography nurtured a slower process, I would tag photos and organize them by album before posting them online. These days, most of my photography is instantaneously captured and shared in a live stream through Facebook, Flickr, and Instagram.
Photography is one of the more difficult creative works to wrangle. Unlike pottery or painting, it’s possible with photography to create thousands of photos. In just one of my photo libraries, I have over 37,000 photos taken from 2004 to 2013.
High quality cameras in smart phones combined with social media integration has made it possible to deliver photography instantaneously. At such a fast pace, there is less time to consider how we might organize and make photography accessible in a meaningful way. This makes photo-centric websites underutilized. Software, such as Aperture, iPhoto, or Lightroom can automatically organize photos by date, location, and even identify people with facial recognition, but automated tagging isn’t available yet.
When I’m using my Canon EOS Rebel T2i DSLR camera, I have several lenses to choose from, and the process of photography slows down. Like eating a meal slowly, there’s more mindfulness of the process and I’m more engaged in the experience.
Embracing Technology. In the early 1980s, I became intentional about embracing computing technology and using it in every area of life. At first it was disorienting and uncomfortable to shift my daily activities to a new unfamiliar platform. The ongoing task of putting information in and getting it out took a while to get used to. I’m now going through a similar shift as I move toward increasingly using small, portable, solid-state, touch-screen devices for more of my work.
From Mouse to Touch Pad. After years of using a mouse for computer navigation it is disorienting for most people to switch to a touchpad. Not only does the interface feel different but the neural pathways in the brain that make mouse activity so familiar and efficient need to be re-created for a new interface like the touchpad. A physiological change the brain and body is needed. New muscles are engaged and old ones are no longer needed. The shift to an entirely different hardware platform with a completely new operating system and user interface is even more challenging.
Slimming Down. I recently decided to start riding my bicycle again to work, and walking more whenever possible. Given my reliance and dependence upon using my notebook computer, I’ve always carried it along with all the acoutrements. For many years, I would put my heavy backpack and accessories in a trailer behind my bicycle. I’m now storing my bicycle in a smaller space that doesn’t easily accomodate the trailer. Also, I’m wanting to carry a lighter load so walking will be easier.
Mobile Devices. Some tasks are intuitive and more easily performed using mobile devices. Text chatting and posting photos to Instagram are examples of tasks where mobile devices are more practical. With iMovie for the iPhone and Garageband for the iPhone, basic video editing and music production are now more easily done on a mobile device.
Large Screens. Some tasks are still more easily performed on a large screen, such as writing content when multiple documents are being referenced. The ability to simultaneously see multiple items on the screen at one time from different programs is unique to the desktop-world since mobile devices typically don’t support multitasking in that sense due to screen size limitations and processor limitations. With mobile devices, the visual aspect of multi-tasking must take place in the creator’s mind since content isn’t in front of you.
Visual Editing. I’ve written many pages of content and articles for the web using notebook or desktop computers. A larger display has always been a preference of mine. I usually keep a window open on the right for reference materials. The convenience of WSWG Visual editing (What you See is What you Get) is essential for creating content to see the formatting in real-time. When designing websites, it’s handy to have a window open showing the results of design changes.
Website Editing on Mobile Devices. I’ve been using WordPress for a while to manage websites. Editing sites using a tablet device has been limiting. The WordPress mobile editor app requires editing in HTML. While I’m quite comfortable with HTML, it’s much easier to use a visual editor when working with images and tables. So, I’ve continued using my notebook computer for creating and editing website content. Recently I discovered an app for the iPad and iPad Mini called BlogPad Pro. It’s a full featured website editor with visual editing and additional features that aren’t even found in the standard WordPress visual editor such as a table generator. Below is a screenshot of the post/page editing screen (click to enlarge). This app is making is possible to do advanced mobile post and page editing from the iPad Mini. This entire article was written and posted using BlogPad Pro – including the image below. The software works much better than the app provided by WordPress for editing.
The Impact of Apps and Websites. Mobile devices are only as effective and useful as the apps allow them to be. Increasingly websites are being designed so that they are easily usable and navigate using a mobile device such as a tablet.
