Surviving First Contact With The Enemy


The wise, Jedi-like Colin Jagoe posted a link about how the COVID19 pandemic is very much like being at war.  This got me thinking about how our behind-closed-doors / business-as-usual approach to managing this crisis has been… minimalist.  This shouldn’t be about maintaining the organizational status quo, it should be about building a resilient, transparent and responsive approach to dealing with an unprecedented social engineering challenge.


The following reflection highlights how a transparent, communicative, engaged leadership approach helps mitigate one of the truths of fighting a war:  “No battle plan survives first contact with the enemy.”     In the fluid and rapidly changing situation we find ourselves in, it might be wise to lean on some military wisdom in our response.


***


I was an air cadet in the 1980s in Mississauga.  One of the major pillars of that program is teaching leadership.  I took summer courses on it and spent at least dozen hours over and above school each week working through cadet syllabus on it.  It’s safe to say air cadets was a seminal experience for me in that it not only showed me how I can best fit into an operational structure, but also how to run one effectively in a changeable environment.


When I was halfway through my cadet career we went up to Base Borden for a March Break training exercise.  Pete Rudin was my flight sergeant and as experienced as a cadet can get being only a couple of months away from retiring.  I was a very keen new corporal.  Our flight consisted of about 35 kids ranging in age from brand new 13 year old recruits up to savvy 18 year old veterans like Pete.  We got put into a capture the flag game against other flights, but Pete did something no one else did.


While all the other flight sergeants split their groups up into the standard squads (one experienced NCO leading 4-5 very excited and inexperienced younger cadets) and ran things top down, Pete differentiated his leadership approach based on the human resources he had at hand.  His plan was to create a massive group of all the new recruits who were anxious and a bit freaked out and move into the exercise with this slow moving but unstoppable unit.  He knew he had a few experienced and gung-ho junior NCOs who wanted to run, so rather than hold them back in the big group he told us to recon where the other teams were and report back.


You can imagine how that felt.  When your flight sergeant acknowledges your esprit de corps and gifts you with a special assignment, your already gung-ho approach steps up another gear.  Things went as you might imagine.  The other junior NCOs and I ran off into the woods full of adrenaline and immediately began finding those little homogeneous squads.  As soon as we made contact we’d run back to the hive, usually with that squad chasing us thinking we were an easy kill… then they’d come over a hill and find dozens of excited youngsters swarming around our flight sergeant, and get retired from the game.

We began hoovering up squads and about an hour in I stumbled across the other team’s flag – the one we had to capture that would end the game.  I barely got out of there alive (if they pulled the flag off your arm you’re considered retired), they had two of their most experienced squads on defence.  I managed to get away and ran back breathless to tell Rudin where the flag was.  Ten minutes later it was all over as our hive swarmed over the hill into the dell where their flag was hidden.  The two squads they’d put on defence couldn’t believe what was coming at them.  Our youngest, tiniest new cadet took the flag and ended the game (I think Pete made a point of that).



Afterwards, I asked Flight Sergeant Rudin how he came up with this bizarre approach.  He said something I’ve never forgotten: “I figured if I tried to keep you guys back with the big group you’d be hard to manage and it wouldn’t help things.  We’d perform better if I didn’t have to micromanage when you wanted to be doing something else that would produce better results for all of us anyway.  The little ones looked terrified, so I wanted to keep them with me and build their confidence.”


We were the  younger team in that capture the flag, with less experienced NCOs – the other team was cocky and confident because they had many ringers.  Rather than open up the rule-book and follow homogeneous protocols designed around top-down control that would have ended up with us losing, Pete differentiated his leadership approach and gave each of his people just what they needed to succeed.  He also arranged things so that everyone was in contact with everyone else and made communication easier by giving us a clear focus to return to, it really was a brilliant piece of planning beautifully executed.


I never forgot that lesson.  In retrospect, it was the centralization of resources, clarity of the planning (it was all done out loud with us all standing around Pete as he elicited ideas and worked out what we were going to do), and the focus on communication that allowed it to succeed like it did.  Everyone knew what we were doing, why we were doing it and how to let the group know if it was or wasn’t working.  When we caught the fourth squad who had no idea that three others had been caught by our big hive, I began to realize what that lack of communication was doing to the other teams.  No battle plan may survive first contact with the enemy, but designing a plan transparently and reflexively with clear communications channels allows your organization to respond to surprises quickly and effectively.



I ended up retiring a sergeant in cadets.  Others have suggested that only making it half way up the command structure is somehow a failure, but I don’t see it that way.  I finished my career as Rifle Guard Commander and Colour Party Commander and occupied a specialist role in our large organization.  The metacognitive awareness of how I can operate most effectively in a large organizational structure was another invaluable result of my time in cadets.  I’m very much a sergeant – good at dealing with tangible, immediate issues in small groups collaboratively and imaginatively (handy classroom teacher skills, eh?).  Given latitude I liked to exercise initiative and move quickly – did this sometimes get me into trouble?  Yep, but the leaders I had recognized those skills and made a point of leveraging them.  That made me feel like a valued member of the organization, rank wasn’t the only thing that defined me.

I was good friends with many of the younger cadets who ended up in charge of our squadron – many of them attended my 50th birthday party last year (we’re all old now, so those year or two differences don’t matter any more – but then they didn’t back then either).  They didn’t make rank about exclusion, privilege and control and they acknowledged their cadets’ expertise and experience by making productive use of them by differentiating the roles they assigned.


This collegial and transparent approach to leadership allowed us to execute the cadet syllabus with precision and flair.  It also allowed us to revise and respond to the unknown quickly and effectively when on exercises, contact with the enemy be damned.  I’m really proud of the things we learned and work we did.  This experience has aided us all in our professional lives as adults.  This transparent, communicative approach has informed much of my teaching practice.  If you asked my students what they find most compelling about my classes, I think many would say that sense of agency – I acknowledge their strengths and honour them by differentiating their work.


I’m missing that transparency, clarity of purpose and engagement now, even though not one of the teens I just described had a post graduate degree in leadership.  If we are indeed at war as Colin suggests, then we need to quickly engage and develop effective communications and a clarity of common purpose, or all of those secret plans being developed behind closed doors won’t survive first contact with an enemy we’ve too often underestimated.  Initiative is lost, but it’s never too late to try and get it back.

Pushing 360° Video Quality on a Motorcycle

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…

A Nice Way to Turn 50…

Thanks to the Ontario Government ignoring the Canadian Charter of Rights and Freedoms and illegally forcing a contract on us, I had my 50th birthday off.  I had an entire year of saved up sick days stripped away, but hey, I got a day off for it.  So much for Charter rights.


I figured the Forks of the Credit would be silly over the long weekend, so I thought I’d head over there on the Friday afternoon.  Still lots of people about, but I got to have a couple of clean runs up and down the twisty bits where I wasn’t on the bumper of a duffer in a cage.  I’m not leaving rubber doing this, and I’m usually within 10km/hr of the limit, but cars through this twisty, technical road are a bit of a disaster.  It was nice to get a couple of runs without worrying about the processing capacity of the driver in front of me.


Photos are taken with a Ricoh Theta V on a custom built mount attached to the wing mirror.  Screen captured in the Ricoh software and modified in Adobe Lightroom:

The switchbacks at The Forks…

The little guy on the side of the road said, ‘woah!!!” so loud I could here him on the bike.  🙂

Always look where you want to go – sometimes that’s over your shoulder!

In the moment on one of the frew curves between me at the Niagara Escarpment.  If I lived in California I would be a regular canyon carver on the weekends.



Beautiful weather, minimal traffic and a frisky Tiger.  It was a good 50th birthday ride.

Exceptional Times

Thoughts from the depths of the COVID19 pandemic: Rather than give in to the digital divide in times of crisis, why not leverage this moment and make moves to resolve it?


***


It has been suggested that due to the inequity of access to technology and internet, our education system should shut down during the COVID19 pandemic.  Rather than surrender to this inequity, why not attempt to address it directly?  We could leverage educational technology manufacturers and create one to one technology access for our student populations on the wrong side of the digital divide.


At the same time we could offer limited access to our public school library learning commons where students would have access to internet.  With appropriate safety precautions (limited numbers allowed, strict hygiene practices, solo seating arrangements), we could take immediate steps to bridge the digital divide and allow some form of education to continue for students across Canada.  Simply turning off the education system for months at a time will cause lasting damage for millions of students.


This is a measured and logical approach to resolving the digital divide (a lack of educational technology access to all students)  that has long plagued education.  Rather than having this pandemic make it worse, why not leverage it to make it better?

Handing out one to one technology for students in need so we can keep moving everyone forward educationally wouldn’t be as expensive as you might think and the alternative is significantly more costly.  Our public schools have developed the network infrastructure necessary to provide internet, so limited access to that infrastructure could still address the needs of social distancing while providing connectivity.

If this pandemic has shown anything, it’s that our ICT infrastructure is more vital than ever if we’re going to move against this crisis in a unified manner; communication is key.  There are existing technologies we could apply to extend school and municipal wireless networking out into the communities that surround them.  With fundamental networking infrastructure in place, some innovative final mile solutions (like Blimpernet – an idea that my students and I came up with last year) could make the internet available to many more Canadians just when we need it.


Wouldn’t it be something if one of the lasting results of this pandemic was that it helped us close the digital divide and improve equity through access to technology in our schools?  That it would also allow our education systems to continue in a limited capacity instead of shutting down is a consequence that would benefit all Canadians.

I sent this to a number of MPs as well as the PM.  I only hope a measured, reasonable response is still in the cards.

Gamer culture, the alt right and online sexism

That link above takes you to a vetted story by our national broadcaster about a PhD student’s academically researched work on gamer culture.  If you can find an academically vetted refutation of these facts (not some dude’s YouTube video) then I’m all ears.  I doubt such a thing exists.  Merely implying that this isn’t true isn’t an effective response either.

 

It’s a salty but accurate explanation
of how the early internet evolved
toward what we have today.

This idea that online gaming culture may act a petri dish for alt-right thinking doesn’t surprise me.  Every year I have grade 9 boys begin my program, find out I game, and immediately begin testing the waters with shockingly racist and sexist language to see if I speak the lingo.  I don’t.  I come from an earlier internet where trolling and trash talk were used to instruct and support the kind of radical egalitarianism the early web was promising, not to protect the diminishing historical privilege of white males.  I used to think their offensive language was a function of living in a rural, conservative community but now I’m thinking that a pervasive, new online culture might be the cause.

The podcast above describes astonishingly sexist online situations and suggests that these aren’t rare.  I’ve run into similar problems teaching computer technology. Trying to keep girls in these courses is an ongoing frustration.  Back in 2014 I called this poisonous environment “nerd machismo” and had a great deal of trouble redirecting how many tech focused boys treated these classes like their own private domain.  In retrospect, if they were immersed onlline in the kind of sexism shown in the podcast above, it’s little wonder they were acting this way.  The odd girl who did appear in senior computer classes tended to drop out after a couple of days of listening to this bluster.  I could hardly blame them.

Girls are being chased out of ICT courses by an online culture that can
be best described as incredibly misogynistic.  In the process they are
missing a job sector with great prospects.

In managing my own online presence I’ve removed any online discussion functionality.  I’m happy to talk to people about what I write and thrilled if they share it but I’m not in the business of vetting comments and weeding out the increasing toxicity I was experiencing.  It became tedious and depressing trying to manage these idiots.  Online flaming has decreased in intelligence and increased in misdirected usage to the point where I don’t read (especially anonymous) online comments any more.  By default now my blogs and other online media do not allow for comments.  I don’t want to spend my time reading and erasing offensive material.  If people want to discuss it intelligently they can leverage their own social media presence to do it.  In some small way this mitigates the savage idiocy of the anonymous online flamer by assigning at least a minimal kind of ownership.  If I’m cutting and running from online engagement (a white, male, early adopter), I can’t imagine what kind of negativity has chased out others.


***


Last month at the ECOO Conference Andrew Campbell did a great presentation on how computer science was stolen from the pioneering women who did much of the coding in the early days:

 

 

When you consider how misogyny has directed the field of computer science in the past forty years it’s little wonder that the online culture arising from all that coding tends toward the same thinking.  The medium delivering the message is being made by the same special interests.  This is the worst kind of systemic sexism.


Between this podcast, my own experiences and Andrew’s presentation I seem to be at a confluence of ideas all pointing to a kind of misogyny that I thought was going extinct.  It’s 2016 but we seem to be wrestling with ideas that would look more comfortable in pre-suffragette days a century ago.


I’m a firm believer in developing technical prowess in everyone.  Democratizing technical know-how is the best defence we have against being manipulated by increasingly invasive digital systems continually rolled out by billionaires.  Excluding half the population from technical literacy simply because of their gender plays right into their hands.  No wonder political movements like the alt-right find such a comfortable home online where the powers that be don’t want you thinking about how it works.  In that place ignorance is power.  In the meantime I get to go to school and interact with children who think this is how you should talk to women:

Screen grabs of what women experience online.
In addition to experiencing harassment much more regularly, young women also experience a much wider
variety and intensity of harassment online.  If you experience this online how must you
look at the people you meet in real life?  I’d be constantly wondering what they really think.

Motorcycle Insurance Money Grabs and a Lean Motorbike Stable

The greatest single downward pressure on the infamous motorcycle equation is the way you’re worked over by insurance for them, especially in Ontario.  If you own one bike you’re likely to be paying about $700 a year if you’re an experienced rider.  If you’re new you can pretty much double that.  


If you buy a second bike, against all logic you’re basically doubling your insurance.  Even though two bikes mean you’re only spending half as much time on each, you get nothing back for that.


If the motorcycle industry wanted to sell more bikes, pressuring the Ontario government to make fair insurance premiums would be a good way to do it.  If you’re paying $700 a year to ride a bike, it should be less than half that to insure a second bike, not double that.  Since you can’t be on both bikes at once your chances of needing insurance drop dramatically.  What would be fair would be only applying the stationary insurance (theft, fire, etc) to a second bike, and perhaps a small fee for the paperwork.  Owning two bikes does not mean double the liability, which is the lion’s share of an insurance premium.


I’d happily budget $1000 a year instead of the $600 I pay for insurance and triple the number of bikes I’ve got licensed.  That’s three times as many vehicles paying road and license plate tax – which helps out the government, and the insurance company themselves would be making more with no increase in liability.  If only they could get past the short term money-grab philosophy they currently run with.  As it stands the ROI on a $2000 a year insurance bill makes it not worth pursuing.


What would that expanded motorcycle stable look like?  Canada’s short riding season means you need to have machine turn-key ready for the few days you can get out and enjoy the weather without it trying to kill you.  I’m currently riding a fourteen year old Triumph Tiger as my go-to bike.  It has been great, but depending on a bike that old isn’t really fair to it.  At The Forks of the Credit last weekend we had the oldest bike there by a decade.  I get a great deal of pride out of that, but I don’t want to start hating on the Triumph if it suddenly develops a fault.  That happened with the KLX and it was gone shortly thereafter.

A new bike would definitely be in the cards.  I’ve long had a crush on Honda VFRs, and they make a great all rounder.  A sporty bike that can also cover distances, and when I sat on one they felt quality, almost jewel like.  As an it’ll-always-be-ready-to-run, dependable bike, it’s a solid choice.  The website is saying this is a $15,000 proposition, but I’m sure I just saw them on sale for a touch over $10,000.



On a naked choice for a new bike I still tend toward the Kawasaki Z bikes.  The Z1000 with it’s cat like robotic stance has long scratched an anime aesthetic itch for me, but the new Z900 does too.  With the taller comfort seat it would fit me well.  The bike is under $10k and looks fantastic.  A new Kawasaki, like a new Honda, would be bullet proof and a good choice for an always-ready dependable motorbike.  Both the Honda & the Z could also handle track days.



The Tiger does a good job of two up riding (it’s a big bike), but sometimes I miss the road focused athleticism of the Concours.  The new one looks spectacular in Candy Imperial Blue.  As a two up tourer it approaches the Goldwing and other dedicated touring machines, but it retains its sports bike heritage, evaporating weight and feeling more like a Ninja in the corners.  It’s a big bike, but I’m a big guy and I look like I fit on it.  With a dedicated long distance road tool like this, perhaps the Tiger would become more adventury in purpose.

With the Tiger and one of the above on hand, in a more insurance friendly situation I’d also have a third bike that would let me focus on the off-road aspects of riding.  


I learned that a 240lb guy on a KLX250 does not add up, so I’d be looking for a 300+cc off roader so that I could keep up with traffic when on the road.  


The DRZ-400 Suzuki has long looked like the bike of choice.  They come up occasionally online.  If insurance weren’t killing it, I’d already own one.  With some frame guards and good sump protection, this would be the bike I’d trail ride and explore farm tracks on without worrying about a traffic line up behind me when I’m on the road.


The Tiger is dependable and a good two up ride, so I suspect I’d pass on the Concours.  Today the three bike stable would be the Tiger, the VFR and the DR-Z 400; a Triumph, a Honda and a Suzuki, but in other circumstances it could be a Kawasaki heavy garage.  If the Tiger weren’t the brick house that it is, I’d have a Concours, a Z900 and maybe even a KTM in the stable… if only I could pay fair insurance rates on them.

Honda Getaway

This lovely little Honda CB500x popped up on Kijiij.  As an icestorm approaches I’m dreaming of being elsewhere, as I often do during the off-season.


Two grand looks like it’ll get the bike air freighted from Toronto to Ecuador.  The South American tour would take me south down the Andes and then finally to Ushuaia before working my way up the Atlantic side to Rio de Janeiro.

By the time I worked my way back up to Rio on the little Honda, it would have done tens of thousands of kilometres across some pretty rough terrain on not the greatest gas.  I’m sure I could find a happy rider in Rio to hand it off to.

Just over 16,000 kms – a nice 3 month jaunt.


Averaging 250kms per day, it’s a 60 day trek.  With some wiggle room, this would be a nice three month jaunt, mid-February to mid-May.  The MotoGP circus passes through Argentina in April, so that’d be a nice thing to be able to ride to as well.

Custom Motorcycle Digital Art

What I’ve got here is a photo of my Triumph Tiger 955i taken as near to fully side on as I could manage it.  I then photoshoped into a outline (trace contour and some negative inversion along with some line cleanup did it).  I saved that image as a vector and shared it with my trusty technology design teacher at work.  She cleaned up the lines a bit (mainly simplifying them) so they could be cut into perspex using a computer controlled router.
I then got an Arduino micro-controller and cut a length of Adafruit neo-pixel leds to fit the length of the perspex.  I soldered some wires onto the neo-pixel led strip and wired them up to the Arduino.  I then installed the libraries to run the neo-pixel strip and ran the basic test pattern code on the Arduino.
 
This is the result:
 


With a bit of coding you could colour code the display to something specific or make different patterns.  The strip along the bottom is 9 leds long, so you could get pretty fancy with patterns if that floated your boat.  I’ve also seen Arduinos run like graphic equalizers, responding to music with different colours and patterns, so that’s another option.


Metres long LED strips can be gotten cheap.  An Arduino can be had for less than $10 if you’re cagey about it.  Three wires and a bit of perspex and you’re ready to go.  I’d guess in raw parts it cost all of about ten bucks to put together, and that includes an Arduino that could do a lot of other things.  If you’ve got a customized bike, a clean photo and a bit of prep and you’d have a disco light version of your specific machine.


***



I 3d modelled the Tiger a while ago using a Structure Sensor.  It snaps on to an ipad and is very straightforward to use.  Once you’ve ‘painted’ in your 3d model using the lasers on the sensor you can clean it up in something like the 3d modelling software that is included in Windows 10.  Here is what an upload of that looks like on Sketchfab:

 

I used Meshmixer to clean up any missed pieces in the original scan and then dropped it into a Dremel 3d printer.  This printer is fairly cheap and low resolution, but the model came out ok.  What I’d really like to do is try and print it in something like the FormLabs Form2.  Their terminator style resin based laser prints are way higher resolution, so you don’t get the blockiness that you see in the additive 3d print process.

You can see how blocky the print is on the clean / top side of the print (the Dremel printer makes up the plastic model like a wedding cake getting layered).  The bottom side with all the extra support pieces that I had to cut off after is much rougher.  Another benefit of the Formlabs printer would be no annoying structural supports to cut off.
 

Like the disco light above, what’s nice about this is that it’s a direct copy of my specific bike.  If you’ve got a custom ride, scanning it with the Structure Sensor and then printing it out on something nice like the Formlabs printer would mean a smooth, accurate scale model of your particular machine.
 
What would be even cooler would be getting my hands on a large format 3d printer, then I’d be making accurate 3d models of fairing pieces and going to town on them in 3d design software.  I still want to remake a sports bike with  textured dragon scale fairings!

It’s Time For You To Go

The ZPD: something all those people critical of
teaching have never heard of, but it’s where
teachers live all day every day.

If your teacher-craft is good you are a natural differentiator, going to great lengths to provide each student with what they need.  Teachers are the pressure point between a system trying to do things as cheaply and generically as possible and individual students all learning from their own context.  That stretch is why replacing teachers with elearning systems or creating enormous classrooms will result in a substantial drop in pedagogical effectiveness.  You need a trained professional to attempt to bridge this enormous gap in a reasonably sized class, at least if you want it done well.


In an optional course like computer engineering this is stretched to extremes.  In the same class I will have functionally illiterate students who verge on being developmentally delayed sitting next to gifted students who so aggressively pursue the work that they are operating well beyond the expectations of the grade or even the curriculum.  I’m the mechanism that tries to make sure both those students (and the other twenty-two in the room) are all in their zone of proximal development, and yes, it’s exhausting at the best of times.


On top of that, because I’m teaching high school students I get to attempt this stunt with kids whose brains haven’t yet developed the ability to forecast the consequences of their actions.  When their amygdalas finally develop in their early 20s their executive functions will come online and their post-secondary instructors will get to enjoy a more complete human being, but we never see them in high school.  Most of the general public are also oblivious to the brain research teachers keep up on.

Because all of that isn’t enough, Ontario also likes to Victory Lap students, allowing graduates who have already finished to come back for another year at great public expense.  The system used to enjoy the extra financial injection that these students brought with them, but cuts have meant that schools aren’t being funded completely to support these students properly any more.  This week I’m spending more attention on two victory lappers than I am on my other 70 odd students who are actually supposed to be there.


I’ve had mixed experience with Victory Lappers.  In some cases that extra year was just what they needed in terms of maturity to prepare them for post-secondary life, but too many times it’s a privileged kid enjoying an easy year in a fish tank they’ve outgrown instead of taking the big step into the unknown.  That this is now happening in an unfunded and overly stretched system is causing stress cracks to appear where they didn’t before.  Maybe a way forward in this is to only allow students with individual education plans the opportunity to victory lap, but whatever we do, it needs to have been done several years ago.  If we could stop playing politics and actually manage Ontario’s education system effectively, we could find cost savings in something like this immediately.
