I’m a New Mac Owner!

I never thought the time would come, but I have to announce I’m a brand new Mac owner! Mind you, it’s not a new Mac, but I am a new owner! 😂

No, it’s not 1987, it’s 2019… (An Apple IIgs prints a “Print Shop” sign in 2019)

The sights and sounds of antique technology. I bought a new ribbon off of Amazon to see if that’s the only thing that was needed to bring this old ImageWriter II to life.

This is a fully operational Apple IIgs with a 5 1/4″ and 3 1/2″ floppy disk drive, color monitor, and ImageWriter II printer. The software running is “The Print Shop” by Broderbund.

Computerized Car Navigation in 1986

It’s easy to take for granted modern car navigation systems. After all, the functionality is built into every modern Smartphone. However, back in 1986, before the GPS system even existed, a couple of yachtsman with an idea formed a company called Etak, which made it a goal to make a navigation system with street-level detail that could be installed in an automobile.

They succeeded. Instead of using satellites, they used “dead reckoning” which compares the car’s location to a fixed spot. A modern (at the time) IBM XT computer running at 4.77 MHz with 128 kilobytes of memory got stuffed in the vehicle’s trunk. An oscilloscope-style green CRT display with buttons was mounted up on the dash, a fluxgate compass was mounted on the back windshield to keep track of magnetic north, and a pair of hall-effect sensors were mounted to the non-driven wheels of the car to count off miles, and the difference in rotational speed between the wheels kept track of corners. Map data was loaded on cassette tapes which each held about 3 1/2 megabytes of information. Users switched tapes whenever they roamed into an area not covered by the current cassette.

The system was about $1,500 and could be installed by a company that did radio and speaker installation in cars. They sold about 5,000 of them. The Etak technology lived on to the modern Internet era, where its map data was used by companies such as MapQuest and TomTom. Etak also created the fixed-map viewpoint (you in the center, the map moves around you) which is still used in all modern navigation systems.

Here’s a video of this incredible system at work: https://youtu.be/CHCCjlSWbHE?t=863 You can also read more about this technology here: https://www.fastcompany.com/…/who-needs-gps-the…

High-Resolution LED Display Graphics

Since the time these high-resolution LED displays were installed in the Nomeland Gymnasium at the High School, I’ve been spending much of my spare time designing graphics, sponsor advertising, and program workflow for the system. It has already been used successfully for several volleyball matches, 9th grade orientation, and now an all-staff District workshop. The variety of technology I get to work with is one reason I love my job and this field!

Like it or not, electric cars are the future.

Anybody in their 30s or 40s now will definitely be living in a world where electric cars, charged by renewable energy such as solar or wind power, will be the majority of vehicles on the road. Major trucking companies have already put orders in for the Tesla Semi based on ROI for delivery in 2019. AND, they release an electric car that does an 8.9 second 1/4 mile with a 600 mile range at highway speeds.Gasoline and diesel engines will go the way of the steam engine in the next 30-40 years.

Facebook’s Artificial Intelligence and ALT Tags

Facebook’s Artificial Intelligence, and ALT tags. #Engadget #alttags

I figured I would post something about this because I haven’t seen it discussed on any forum I am familiar with on the Internet.

Facebook reveals a little information about the information it collects from the pictures you post in the form of ALT tags. ALT tags are included in the raw HTML code of nearly every website you visit. They are primarily used to briefly describe a particular picture, image, or graphic for users that can’t view images, either because they are visually impaired, or their Web browser doesn’t support it.

By inspecting the HTML code of anyone’s Facebook profile, you can see some of what Facebook can recognize in your photos. Take for instance these examples on my own profile. In the first example on the thumbnail with my girlfriend and I in the car, Facebook believes it sees 2 people, smiling, sitting, outdoors, with sunglasses and a beard. This is amazingly accurate (it HAD been a few days since I shaved!) In the second example on the thumbnail of me jumping my four-wheeler at Jordan Supercross, Facebook believes it sees one or more people on a motorcycle outdoors. Again, not too shabby on Facebook’s part!
If you care to experiment a little, what other criteria can you find that Facebook’s AI can successfully identify? Share here!

The last T1 has been disconnected!

Once the configuration was done, the only thing left to do was plug in the fiber! As you can see, a few Nerstrand Elementary School students happily helped out with this process. With a simple, positive “click” of the fiber-optic patch cable into the transceiver, Nerstrand completed their upgrade from the two trunked T-1 lines offering about 3Mbps of bandwidth, to the 10000Mbps of bandwidth now at their disposal. The speed is exciting, but even more exciting is the capacity this line will give the School for bringing in more devices and perhaps even having a one device per student option down the road. Thanks Amelia and Stefan!

Stealing 3D Models by Audio Recording a 3D Printer

A bright professor at the University of California-Irvine discovered it’s possible to steal the design of a 3D model by simply doing an audio recording of the 3D printer printing it. Apparently, they have demonstrated a 90% accuracy of model reconstruction using this technique. Simply having an employee working at a manufacturing facility with a cell phone on them could invite the possibility of industrial espionage if they were to give such a recording to a competitor. Fascinating proof of concept!

1992 SouthLAN/MNWADA Joint Packet Radio Node Install at Faribault

During much of 1991, the SouthLAN and MNWADA Packet Radio Clubs in Southern Minnesota planned and designed 3 high-speed packet radio nodes to be installed at Apple Valley, Faribault, and Dodge Center. The Faribault site, MNFBL:N0QVC-1, would have a 1200 baud user frequency on 145.01 MHz, a 9600 baud backbone towards Dodge Center on 430.95 MHz, and a 19.2 kilobaud backbone towards N0DAI-1 in Apple Valley on 430.55 MHz.

This was one of the first high-speed amateur wireless data communications services in the upper midwest, and passed hundreds of messages between the Twin Cities Metro area and Rochester, MN throughout the 90s and early 2000s. All locations used WA8BXN’s MSYS bulletin board system and G8BPQ nodes, with a combination of Kantronics Data Engines and D4-10 radios. The N0QVC-1 Johnson RSDL VHF radio is still used as an APRS node on 144.39 in the Faribault area at this location as of 2016.

The video is a glimpse of the antenna and TNC install at the Faribault location on May 23, 1992.

October 21, 2015

Well, it’s here! Tomorrow is the day where everyone in “Back to the Future II” were driving flying cars, cruising on hoverboards, and wearing jeans with their pockets turned inside out. Our “present” future might not be quite as exciting, but hey, at least we have the Internet!

MisterHouse control for a Samsung Smart TV

UntitledAnother piece of my home, now automated. With assistance from a thread on the Samygo forum, I created a module for the MisterHouse Home Automation System which allows it to control a network-connected Samsung Smart TV. For instance, when you leave the house for more than 10 minutes, it could turn the TV off for you. It could also switch the TV automatically to match your favorite show schedule, or switch to an HDMI input to monitor a surveillance camera if motion is detected on your property. It’s available right here for free:  https://gist.github.com/hollie/ed1fa39871e93e36e24e. It’s written in Perl so it’s cross-platform or can be adapted for other uses.

I’ve tested this with my Samsung UN40EH5300 and it works well. It should work on pretty much any Samsung TV that has an open port 55000. The code is based off of another Perl/HTML program from http://forum.samygo.tv/viewtopic.php?f=12&t=1792 created from some Wireshark traces.

To use this code, you’ll have to modify a few things:

– Change the IP 192.168.2.155 below to your own TV’s IP Address.
– Change $myip to your MisterHouse server’s IP Address.
– Change $mymac to your MisterHouse server’s MAC Address.

The 9-year-old Programmer

In response to the ZDNet article that Chad Elstad posted (you can read “The Mac’s 30th: What’s Your Story?” here: http://www.zdnet.com/the-macs-30th-whats-your-story…/ ). When I was 5 years old, I remember printing out computer programs on our Apple ][+ (Remember PR#1, LIST ?), and then trying to type them in to my Commodore PET computer. My first lesson in incompatibility! When I was 9 years old, I created a Baseball game in BASIC using lo-res Apple graphics (pictured below). I’m still a huge fan of the Apple ][ platform and I still have a working Apple ][gs that gets use from time to time…

Changes in Technology Over Time

Back in January, I was asked some questions by Amber Hallet from the Faribault High School Journalism class in regards to technology.  Here’s the insight I had.

What are some things that have changed over time with technology?

Technology rapidly changed from the 1960s forward.  The Apollo Space Program in the 60s showed the average citizen just what was possible with electronics and a lot of brainstorming (and money!).

THIS IS PROBABLY IN 1981. MY COMMODORE PET COMPUTER AND A TELETYPE MACHINE

We use many of the same kinds of equipment as we did years ago.  That is, equipment to record and playback sound, and equipment to organize files and folders.  Improving technology has allowed this media to go digital, be better fidelity, and be a lot smaller in physical size.  Instead of record players and cassette tapes, we now have compact discs and MP3 data files.  File cabinets are getting replaced by file folders on hard drives.

In the last 10 years especially, technology has become “cool”, and nearly everyone uses it.  Back in the 90s, you were labeled a “geek” for tinkering with portable electronic devices or computers, but now you’re not with the times if you don’t use them.

With improving technology comes an ever-increasing need for everyone to have a more thorough understanding of everything.  The learning curve keeps getting steeper.

What was the technology used when you were a child?

I was a lucky kid and was fortunate enough to have a father that loved tinkering with technology.  When I was 4 years old (in 1982), we had both an Apple ][+ and a Commodore Pet computer.  In those days, having a computer for personal use was not mainstream, and they were usually purchased by experimenters.  There were no easy-to-use graphical interfaces or mice.  Everything was input into a computer by keyboard, diskette, or cassette tape, and you needed to remember a different set of commands to make each individual program function the way you wanted it to.  Many people created their own programs because there might not have been software to do what they wanted (or it could have been very expensive).

Did people use a lot of technology when you were growing up?

People just started to buy VCRs and Video Cameras were I was young.  Our family took a video camera along on several of our family vacations in the early-to-mid 1980s.

MY MDF AT THE HIGH SCHOOL

It was amazing how many people came up and talked to us, thinking we were recording a story for the evening television news.  You don’t get that reaction now.  In fact, many of the equipment you can get now is nearly the same fidelity as what the “big guys” are using.

This may not be a popular opinion, but I feel piracy has always advanced technology and encouraged people to accept and embrace it.  For example, when people found out they could make copies of rental movies on their VCRs at home, people purchased the equipment to do so.  When people discovered they could download free MP3s from the Internet through services like Napster, they embraced MP3 as a viable format and purchased the equipment to take advantage of it.  In both cases, the piracy was cracked down on, but it left those formats with a huge market share, and opened up the possibilities for future (legal) development of the technologies.

How was going to the doctors different with not having equipment they have now?

Computers are everywhere.  For a typical person going to a clinic, computers are used to register you at the front desk, computers are used by the nurse to record your vital statistics, and computers are used by the doctors to transcribe entries in your medical records.

What was the coolest device when you were a child?

I had this Casio Data Bank watch when I was in Junior High School in the early 1990s.  It stored phone numbers, appointments, memos, and had a world clock, timer, stopwatch, and alarm.  You had everything right on your wrist like Dick Tracy.  It was every geek’s (well, at least my) dream.

How did people react to the new technology?

Everyone forms into one of about three groups when you show them a new piece of technology.

ME HARD AT WORK

ME HARD AT WORK

You have those that are frightened to death of it, those that want to grab it and play with it right away, and those that don’t care one way or another.  Getting people to accept new technology has always been one of our greatest challenges at Faribault Public Schools, as it is at most places.  Usually when you can prove that something new will save somebody time or let someone do their job better, they slowly accept it (sometimes with a little extra needed encouragement).  For example, we installed our first District wide e-mail system in 1997.  It took a good two years before people really embraced it and found out how it could benefit them.

What kind of things didn’t you have back when you were growing up?

They certainly didn’t have many video games, at least what we would call video games today.  I think most people have seen and laughed at the original television “Pong” game, where you hit a white dot back and forth across the screen with a couple lines that you would control with game paddles.

Everyone had landline telephones.  In the early 80s you could even call people with just the last 5 digits of their phone number.  Cellular telephones weren’t even considered an option unless you were a businessman, lawyer, or CEO, because cell phones were way too expensive for the average person.  At that time, cell phones came with their own bag, a big antenna, and needed to transmit a lot of power in able to keep a phone call active.  People could expect to pay a couple dollars a minute, and that wasn’t including the price of the phone.

How has our school changed with getting undated on technology?

The bottom-line goal of pretty much every school district is to prepare their students for life-long learning.  In society today, you need to have at least a basic level understanding of how to use computers and logic to do basic things.

...ONE WITH 1.8TB OF SPACE, AND ONE WITH 1.5TB OF SPACE. EACH SUBSYSTEM HAS AN EXTRA HARD DRIVE (BOTTOM) THAT WILL TURN ON IF ONE DRIVE IN THE ARRAY FAILS. EACH INDIVIDUAL DRIVE SHOWN HERE IS A 300GB SAS HARD DRIVE.

…ONE WITH 1.8TB OF SPACE, AND ONE WITH 1.5TB OF SPACE. EACH SUBSYSTEM HAS AN EXTRA HARD DRIVE (BOTTOM) THAT WILL TURN ON IF ONE DRIVE IN THE ARRAY FAILS. EACH INDIVIDUAL DRIVE SHOWN HERE IS A 300GB SAS HARD DRIVE.

Our school district tries to purchase the software that students will need some knowledge of for college and beyond, and then give them a good understanding of how to use it.  Teachers continually need an advanced understanding of technology concepts in able to effectively instruct students at all grade levels.  And of course, none of this is possible without newer computers, servers, switches, routers, staff to fix and support them, and the financial resources to buy that equipment and personnel.

When you first started working here what was here for technology?

I graduated from Faribault High School in 1996 and started working at Faribault Public Schools full-time in 1997.  At that time, we had Internet connectivity just in the media center at the High School.  None of the schools had a network connecting them together.  In the offices at each school, there were 2 or 3 IBM PS/2 computers connected together with coax cable that formed a makeshift network.  The schools used Macintosh computers at a time when Apple went through several engineering problems, and it was always a struggle to keep them up and running.  If you wanted to transfer files from one computer to another, you had to copy them to a 3 1/2″ floppy disk first.  Several labs at the High School still used the bigger 5 1/4″ diskettes.  Teachers still routinely used movie and filmstrip projectors in their classrooms.

How has it changed since you have been working here?

The Faribault Community passed a levy referendum which gave our District about 4 million dollars to upgrade its technology.  In 1997, we installed a wide-area network which connected all of our schools together, and we purchased Internet access which was then routed to each building.  Each building got a complete video system which sent television programming to each classroom.  Teachers could finally make phone calls from their own classroom telephone instead of walking down to the office.  It was exciting for me to get in on the ground floor of such a large project.  Since then, we have upgraded all of the network equipment District-wide once.  We have expanded the bandwidth of our Internet connection 4 times.  We are now on the 3rd generation of computers in the classrooms and around the 4th generation of computers in the labs since the original referendum.  Almost every classroom district-wide now has a high-definition video projector hung from the ceiling instead of televisions.  Smartboards and document cameras have begun replacing whiteboards and overhead projectors.  Lastly, I have seen our staff in the last 15 years learn and better adapt to technology.  It has not been an easy road, but I think teachers have done a wonderful job including technology in their curriculum.
