When Assistive Technology Doesn’t

Recently, my son was undergoing his IPRC process to enter high school and I’m suddenly privy to how parents experience this aspect of the public education system.  The parties at this meeting seemed to genuinely have my son’s best interests at heart, but there are unseen forces in the education system more interested in saving money than promoting pedagogy.


One such area is technology support for IEPed students.  The goal here is to provide digital tools that allow students with special needs to keep up with their class work.  In many cases this can mean something like a Chromebook, which is essentially a web browsing laptop.  I’m not a fan of Chromebooks, they are a corporate means of collecting users into a closed ecosystem.  The intent of Chromebooks is to pass any online experience through Google’s corporate lens (Chrome) and to keep people within that singular view in order to benefit what is very much a for-profit business.  

Google struggles to treat education and students in particular as anything other than a commodity because people’s internet attention is why Google is one of the richest companies in the world.  Google is very aggressive about maintaining its monopoly which is why I’m reticent about things like GAFE, evangelizing groups like Google Certified Teachers and the Chromebooks.


Google is a powerful tool, no doubt, but if it’s the only way you ever interact with digital technology then you aren’t particularly digitally fluent, any more than you could call yourself truly literate and knowledgeable if you only ever read one publisher’s books.


The default response from the school board when we began talking about replacing my son’s very old (he takes good care of it) laptop was to give him a Chromebook.  Since we only pay lip service to developing digital fluency in Ontario and graduate a large majority of digital illiterates, this seems like a cheap and easy way to hand out tech, but in this case it is a kid who is already digitally skilled and who intends to make computer technology his life’s work.  He is already competing in robotics competitions and building computers.  The courses he has signed up for in high school focus on digital engineering.  Giving him a Chromebook is like giving a carpenter a toy hammer and expecting them to frame a house.  It’s neither individually appropriate nor particularly useful.

I have been pushing to get him the tools that he needs to pursue his interests, but I’m speaking for the trees here as well as for my own son.  I teach computer technology and have a high preponderance of ASD students who have a great interest in and a neuro-atypical approach to technology that allows them to tackle it in interesting, unique but usually never time efficient ways.  Handing any of those students a Chromebook is like giving a mechanic a twelve millimeter wrench and then telling them to disassemble an engine with it, in an hour.


When he is learning electronics next year in grade 9, he’ll need to install Arduino on his computer and then use it to code circuits.  It’s free on a ‘proper’ computer running Windows, Linux or OSx, but Arduino can only be done on a Chromebook with a monthly fee (not covered by the school board).   If he wants to run RobotC for his robotics classes, he can’t do it on a Chromebook.   If he wants to run 3d modelling software?  Code in the IDE of his choice?  Run the plasma cutter software?  Sorry, none of those happen on a web browser.  If all we’re aiming to do is teach kids how to browse the internet like the consumers we want them to be and through a single, corporate lens, then we’re doing a great job pitching Chromebooks at them.



A Chromebook isn’t cheaper than a basic Windows laptop.  It is only a browser whereas the Windows PC can install a massive ecosystem of programs for a wide variety of purposes.  The only advantage is that the Chromebook is easier to manage.  Because you can’t install anything that isn’t a simplistic Chrome extension on it, you have less headaches with software conflicts; it does less, is easier to manage and does a great job of performing it’s primary function:  feeding the Google data mining machine with much needed fuel.  Pedagogy designed to expand digital fluency in our students isn’t the reason why Chromebooks are now ubiquitous.  Management of educational technology is easier if you drink the koolaid and get on the magic Google bus where you don’t have to worry about all that messy digital diversity and the complications of actually teaching students (and teachers) how technology works.  Google (and Apple, and Microsoft) are happy to usher your classroom in to a closed system for your own ease of you, learning how technology works be damned.




In discussing this issue with the school board I was told that my son doesn’t need a full laptop because the specialty classes that require that software will supply it in class.  His IEP specifies that he be given extra time to complete work, but that is impossible if the technology needed to do his class work is only available in a particular classroom.  How does that help him finish his work after school, or on a weekend?  It doesn’t help him if he is trying to do work during his GLE support period either because other students are using the in-class equipment while he is elsewhere.  There is no guaranty that the technology would be available at lunch or before or after school either, so the ‘what he needs will be in the classroom’ answer seems to be intentionally ignoring the extra time his IEP clearly states he needs.


Differentiation of assistive technology with an eye on customizing it to specific student needs is exactly what the IEP (INDIVIDUAL education plan) is supposed to be doing.  If we were going to begin to take digital fluency seriously, assistive digital technology that encourages a diverse digital ecosystem and renders a wider understanding of how technology works would be a great place to start, especially with digitally interested students.  


A Chromebook should be the last thing suggested.  This, or course, begs the question:  if Chromebooks aren’t any cheaper and don’t improve digital fluency, why are we using them at all?  Well, it makes our monopolistic corporate overlord, um, partner, happy while not being any cheaper and doing less, but it sure is easier to manage.  


Whoever this is a win for, it isn’t providing my son with the technology he needs to succeed.  It also puts pedagogy of promoting an understanding of the technology we’ve made an intrinsic part of our classrooms on the back foot.  As near as I can tell, other than feeding a corporate partnership and rolling out something so simple it can’t really break (or do much), there is little to recommend the Chromebook, especially as an assistive device for a student who will need things it can’t do in his classes next year.

Stealing One Back From Winter II

I stole one from February last year.  This year the weather aligned again and I was able to get a ride in between snow storms.


It was a cold commute in before 8am, about freezing, but clear and sunny.  I took it on the chin knowing that it’d be worth it on the way home.


Coming out of work past 4pm it was about 10°C and windy, but I can go all day in ten degrees.  I took the long way home, 27 kilometres of leafless trees, rivers with cubist banks of ice shoved into  the new mud by our recent floods, and a sky so winter blue that it wriggles before your eyes; all while leaning into fifty kilometre hour gusts of wind.  It was glorious!


I can still operate the bike without a thought, but I missed all sorts of apexes.  I’m rusty with neglect.

Note the snow pile in the middle of the road….

Why You Shouldn’t Base Your Classroom On Hacker Mythology


Like many social trends, hacking came into education late. Decades after the concept reached world wide understanding in technology, education took it up as a great leap forward and a way to catch up with the times, except everyone else has moved on, again.  WIRED recently published an article that demonstrates technology’s evolving relationship with the hacker ethos.  In questioning the value of hacking as a moral and useful way of thinking, this article raises some interesting questions about the many teachers who want to hack the classroom, or teach children the magic of hacking.


Honesty, ethics and scientific method?  Surely it’s much
better to be a cool hacker in a classroom, right?

If, as Joi Ito suggests in that article, “the hacker archetype had found its highest articulation in one Donald Trump”, then perhaps it’s time for educators to rethink their hacking fandom.  At its roots hacking is an act of hubris designed to beat a system at all costs.  It is driven by pride and arrogance and the results always justify the means.  A successful hack is a forced, rushed, short-term result that only has value to its user.  Hackers don’t build things, they break things, twisting the intentions of designers and diverting shared resources for their own needs; hacking is an inherently self serving and destructive act.


…but I can hack a fix that will save us in this moment
but will take weeks afterwards to undo or everything
will fall apart – hacks have nothing to do with sustainable
engineering.

In certain circumstances (say, Scotty on the Enterprise jury-rigging together some dilithium crystals to make the warp drive work and save everyone’s lives), a hack might be just what you need, but to base your personal knowledge on hacks, or worse, teach it to many people as curriculum, is madness.  Whenever someone hacks together a solution in a complex system, it weakens the system.  You might get what you want out of it in the short term, but capable people will need to come in afterwards and repair what you’ve done or else the system will eventually fail.


It might seem romantic and exciting to call hands on learning hacking, but it’s also very inaccurate, to the point of being damaging to the students learning it because it doesn’t teach them effective engineering.  It is akin to teaching accounting by showing students how to cook the books, or teaching a sport by showing students how to cheat to win it.  As they mention in the WIRED article, the Russian team’s hacking of the last Olympics shows a staggering lack of understanding; the point isn’t winning at all costs.


As a former IT technician and now technology teacher I’ve always wondered why I find the whole hacker thing so eye-rollingly tedious, but in retrospect it was because I was the one who had built the thing they broke, and then had to fix their ‘ingenious hack’ so that the whole thing would work again.  It’s difficult to see a hacker as some kind of genius when you build and service a complex hardware and software network that serves hundreds of people well only to watch it get broken to serve one selfish person.  Yet many educators hold up hacking as this magical process that lets you beat technology.  Perhaps that’s what’s at the bottom of this, and opportunity to attack the technology that so many people feel is enabling them to belittle themselves.

“There is a trend in software development away from the ‘hacker’ jury-­rigging into a mature field, where things are ‘proven’,”

Virgil Griffith

You don’t have to advocate for technological terrorism
to get into teaching science & technology, you just
need to spend some time understanding it.  It
isn’t magic, it’s knowable and teachable.



That mature field is called engineering.  It doesn’t have the gung-ho and catchy mythology of hacking, but it’s what builds space shuttles, Internets and makes the rest of modern society possible.  It is a creative and powerful expression of human thought made tangible and something that everyone should have at least a passing experience in otherwise they are ignorant of how the Twenty-First Century works.


If you want to have Maker Spaces and encourage hands-on learning I’ll be the first to applaud the effort, but you don’t need to dirty the name of technical creation with hacking, because it has nothing to do with it.  You’re encouraging a cheating-to-a-solution-at-all-costs mentality when you use the term hacking.  Engineering is a collaborative act of creation with a result that is beneficial to many people.  The reason hacking isn’t is because it has little to do with creation and is usually motivated entirely by selfish need, that’s why it’s usually a solo effort.  Is that really what you want for your students?  Ruthless, deterministic and selfishly motivated hands-on learning?


As educators I think we can do a bit better than that.

Bike Pickup in the Black Hills

The Dakar has me all dual sport fixated at the moment.  To pass the never ending Canadian winter I’ve been looking up hard to find bikes and then seeing what it would take to go get ’em.

For $3000US there is a Yamaha Ténéré for sale at the Power Brokers of the Black Hills out in South Dakota.  That’s a capable dual sport named after part of the original Paris to Dakar race.

The cunning plan would be arrange to pick up the bike in the spring.  It’s a few hundred bucks to fly out to Rapid City.  It happens to be right by the Black Hills and Sturgis where the big Harley thing happens.  I’ve got no interest in that, but the Hills are supposed to be lovely riding, and only four hundred miles west is Yellowstone.  I’ve always wanted to see the mega-volcano that will eventually wipe out most of the human race.

It’s a long way back to the East after finding the Ténéré 

After hitting Yellowstone it’s a long arc back to the east.  That isn’t what the Ténéré is about, but if I did it focusing on back roads and trails, it’d be an interesting way to find my way home.


It’s over 700 miles east before I get to Deluth on the west end of Lake Superior.  From there it’s still a long way home.  In previous dream rides Deluth has been the apogee of around the Great Lakes rides.  This time it would be the half way point on a long ride east.

Classic Motorbike Pyrenees Trail Riding Fantasies


The legendary Austin Vince put out the video below about this year’s orienteering trail rides in the Pyrenees in northern Spain:

Come map reading and trail-riding with me this summer. Watch this film with the sound up and note that the early bird offer ends in a week. This one is for Tim Kent and Del!
Posted by Austin Vince on Friday, January 12, 2018



If there was ever an excuse to load up a shipping container with old enduro bikes and send it to Europe, this is it.  The Twinshock Trailfinder is a two day event that focuses on older bikes (with twin rear shocks).  I’d dig up four old XT500s, clean them up and have them ready to go, in team colours.

Some soft luggage would make them as touring ready as they are going to get while keeping everything as light as possible.  The Trailfinder event starts on June 6th in Tremp, Catalunya, Spain and runs until June 8th.  An option is to container the bikes over to Antwerp, Belgium.  It’s a two thousand kilometre ride if you go the pretty way around through the Alps down to Spain.  Two thousand kilometers on thirty-five year old enduro bikes is pretty hard core, but that would kind of be the point.

If the container got into Antwerp mid-May, we could get them sorted out and on the road by May 21st.  We could then wind down through Belgium, Luxembourg, Germany, Switzerland and France before reaching Spain.  At 300kms a day that’s a seven day trip.  With a couple of days off in there to explore, we could roll into Barcelona at the beginning of June and get the bikes sorted at the Yamaha Motor Centre before heading up to Tremp the next week.


Rather than get all GPSy with the ride down, we could do it all with survey maps like the ones used in the Twinshock Trailride.  By the time we found our way to Spain we’d be very familiar with how European survey maps work and would be able to find our way around without looking like lost North Americans.

After three days of trail riding with THE VINCE in the mountains, we could then spend an extra week getting better at it now that we’ve had a pro show us the ropes, maybe with some Jo Sinnott style wild camping in there.

When we’re all done we could find some storage for the bikes and park them up, waiting for the next time someone needs to go trail riding in Spain.

Digging up old, twin shock enduro bikes is tricky, especially in the icy wastes of Canada where old machinery quietly rusts away under the snow and salt.  Ten years in Canada is like thirty anywhere else.  Looking country wide, the only XT500 I could find was in Victoria BC, over four thousand kilometres away.

Expanding the search into The States means I might be able to find non-rust belt bikes that have had easier lives.  Unrestored but road worthy bikes look to be about two grand.  Restored bikes go for over three thousand.  There is one in North Carolina, and one in Mesa, Arizona.  With some some searching and a US broker I think I could collect together four road worthy or thereabouts XT500s for under ten grand, and then spend some more prepping them.

If I started now I could probably have the bikes at hand by the end of February and then spend March sorting them out.  April could be spent breaking them in and shaking them down for any last minute issues.  They’d be shipped the end of April to show up in Antwerp when we needed them.

I’d be dangerous if I had money and time on my hands…

Partial Solar Eclipse Astro-Photography


October 24th, 2014 there was a partial solar eclipse at sunset up our way.  I was on the rear deck with the Olympus PEN EPL3 watching it go down.  All shots with the long 300mm zoom lens.



Typical shot data looks like this:
 f/22 1/4000150 mm ISO1000 for the lower light shots and similar settings with wider aperture for the brighter shots – I’d rather everything stay sharp with as big an F stop as I can manage.  No filter, believe it or not.

Bottling Lighting: Long shutter night photography of the sound and fury

Taken on two consecutive summers in 2010 and 2011 using old cameras I can’t remember.  The first two are from 2011 and happened right after sunset with some lingering light in the sky.  The second set are from 2010 and happened several hours after sunset.

Long shutter shots (15-30 seconds) with preset focus and relatively low ISO settings.  All done from a tripod, obviously.

On Bike 360 Video

Originally posted on Tim’s Motorcycle Diaries.

I’ve been messing around with 360° immersive video at work.  One of the best ways to quickly get familiar with the technology is to use it in a difficult circumstance so you can find its limitations.  At work we’re building immersive video to show a virtual walk-through of our school.  If the gimbal and camera we have will work on a motorbike, it’ll work stuck to a kid’s head as they walk through the school.

There are a number of barriers to admission with 4k video and image stabilization.  Fortunately, the 360Fly4k windshield mount I have is so over engineered that it easily handles the weight and motion of the gimbal and camera rig.

I’ve previously done 4k video with the 360Fly4k, but it has a big blind spot on it, so this would be my first true 360 4k video.  The Fly is a tough thing that takes great footage, but I’d describe it more as a 300° camera than a true 360 one.

This 4k 360 camera is the Samsung Gear 360.  I’m running it off the camera because the app won’t run on my Android non-Samsung phone because I guess Samsung don’t want to sell many of these cameras – it’s kind of a jerk move on their part so if these things don’t sell (because you have to have a Samsung phone to access it remotely), then they’re getting what they deserve.

The Gear 360 has a small screen so you can see settings and using the buttons is fairly straightforward, though you’ll find yourself constantly accidentally pressing buttons while you’re handling it.  The Ricoh Theta 360 is still my ergonomic favourite in terms of control and handling, and they just came out with a 4k version of the Theta – perhaps they’ll lend me one to test.

The gimbal is a Moza Guru 360°Camera stabilizer.  The typical gimbal design has weights to the left or right of the camera to keep things balanced, but on a 360 camera that means you’re blocking all sorts of sight lines.  The Moza gimbal is vertically stacked with the weights hanging below, mostly out of sight.  It has a power button and a push button joystick that lets you set shooting modes and centre your camera so it’s looking where you’re going rather that looking down the ‘seams’ between the two cameras.

Most 360 cameras are actually two or more cameras working together.  The resulting footage is then stitched together in software to make an every direction video.  The raw footage from the Samsung looks like this (on left).  A front and back facing fish-eye camera capturing separate footage.

Because both cameras are capturing different scenes, you can often see where they are stitched together because of a difference in ISO which shows up as a clear line of brightness difference (on the right).  They all tend to be identical, fixed-lens cameras, so the aperture and shutter speed tend to be identical.

The first test video has the Samsung camera set at highest resolution (4096×2048 pixels in video) and 24FPS.  The gimbal is in locked mode, so it’s always looking in the same direction even if I go around the corner.  The gimbal provides smooth video by taking the bike’s motion out of the video (it’s always looking in the same direction as the bike and I rotate around the shot), but a bike’s motion is one of the best parts of riding, so for the second shot I set it in tracking mode so it followed the bike’s motions.


Uploading it to YouTube out of the Gear 360 Action Director resulted in a flattened video that doesn’t allow you to pan.  In order to produce that kind of video in the G360-AD (what a ridiculous name), you need to PRODUCE the video in the software and then share it to YouTube from within the program.  My issue with this is that when you bring the program in it takes an Intel i7 VR ready laptop the better part of twenty minutes (for less than ten minutes of footage) to process it before you can do anything with it.  When you produce it (again) for YouTube you end up waiting another twenty minutes.  The Ricoh Theta saves the video (albeit 1080p equivalent) in a fraction of the time and the resulting saved version is 360 ready for YouTube; the 360Fly software is likewise efficient at 4k.  I’m not sure why I have to wait forty minutes to produce less than ten minutes of footage on the Samsung.  I know it’s a lot of data to work through, but it isn’t a very streamlined process.

So, after a lot of post processing, the 4096×2048 360° video out of the camera shows up on YouTube at 1440s (s stands for spherical rather than p – pixels – spherical footage is stretched across a wider area and tends to look less sharp).  I’m not sure where my 2048s footage went – I imagine part of that big post processing was to shrink the footage to fit on YouTube more easily?

If you click on the YouTube logo you can watch it in YouTube and adjust the resolution (bottom right) to see how it looks (make sure to do it full screen to use all your pixels).  If you’re lucky enough to be watching it on a 4k display, this will come close to filling it.

The quality is excellent, the microphone remarkably good (they get beaten up pretty badly on motorcycles), but the awkwardness of post processing and the ergonomics of the thing don’t make it my first choice.  Trying to manage it with gloves on would be even more frustrating.  What you’ve got here is a good piece of hardware let down by some weak product design and software.

The software does offer some interesting post processing options in terms of wacky arts filters, but if you’re shooting at 4k all this does is drastically reduce the quality of your video.  If you’re going to use those filters film at way lower resolution so you don’t have to wait for hours while they process.

I’m aiming to go for a ride tomorrow to look at the fall colours after our first frost.  I’ll bring the Samsung along and see how well it photographs.  It’s promising 15 megapixel 360 images and high dynamic range landscapes, so I’m optimistic.  Photography is timeless and my preferred visual medium anyway, I find video too trapped by the continuity of time.  Maybe the Samsung will be a good photography tool.  Of course, I won’t be able to fire the thing remotely because I don’t have a Samsung phone…

Follow up:

The next morning I set up the camera on the gimbal for the ride to work.  The camera epically failed to catch any of the magic of the morning mist.  The video I got was starting and stopping every minute and the footage was a mess, full or artifacts and unusable.

Compared to the robust Ricoh Theta (which I’ve had out in light rain with no problems) or the bullet proof 360Fly4k, which I’ve left filming through full on storms, the Samsung gave up the ghost at a bit of fog on an otherwise sunny morning.

This is not a tough camera by any stretch.  Dainty might be a better way to describe it.  For something that’s supposed to catch the world around you, it’s best used indoors.  Yes, I’m bitter that I couldn’t catch anything of that glorious morning ground fog.

Simulated image indeed – this camera wouldn’t work that close to an ocean!  If you’re looking for a resilient, tough, outdoor camera, this ain’t it.

Super Moon Astro-Photography

It was a cool, clear night when we had 2017’s December super moon, so photos and video ensued.  The longest lens I’ve got is a fixed Nikon Coolpix P610.  It’s a whole camera that costs a fraction of the equivalent SLR zoom.  Since it’s build to use that lens, even though it doesn’t let a lot of light in, it does a lot better than you think it might.  The photo and video below were taken with the P610 on a tripod at about 8pm once the moon had cleared the horizon.

Last Ride of 2017

A last double digit day before the snows fell meant one last ride at the end of November.  Photos all on the Ricoh Theta 360 camera.  


It’s hard to stay ahead of the dark this late in the year, so some pretty heavy photoshopping happened on these images (the Theta has a fixed lens so only so much light gets in)…
