Tracking My Heart Rate

I’ve always had a slow pulse. When I was in my last year of high school I was in a pool training for water polo 10 to 12 times a week. When I took my pulse in the morning, it was usually between 32 and 35 beats per second. Now when I take my pulse, usually after my morning meditation, it tends to sit between 49 and 43 beats per minute.

It’s healthy to have a nice slow resting heart rate, but sometimes it can hinder me too. Sometimes, when I’m not active, I can feel tired and lazy. Especially after I eat a big meal. I think it’s because while my body focuses on digestion, my slow pulse doesn’t feed the rest of me enough to keep me going when I’m sedentary. So, I tend to move around a lot after lunch, because I’m not too productive sitting at my desk just after a meal.

I’ve recently been tracking my heart rate with my phone. As I mentioned, the first time is resting, after my meditation, the second time during my workout. The App works by putting my finger over the camera, with the light on. The problem is that I just had to switch phones and this new phone uses a camera that’s farther away from the light than my previous phone, and my measurement during or usually just after activity tends to fail and force a retry. This can happen several times and my heart rate is slowing while I do this.

I shouldn’t let this bug me. I can calculate my pulse without the App, but I like having it track my progress and it bugs me that I can’t get it to work easily. I’m going to have to try a new app, one that works for me, rather than fight me. I like tools to track my progress, that’s why my sticker chart works so well. So I need to find a new tracker, and surrender the fact that I paid for this App… which, while a nominal fee, wasn’t enough to keep my feeling frustrated on a regular basis. Our tools need to work for us, not against us.

Digital, collectible assets

Bitcoin and other cryptocurrencies are assets that have value because they have a finite number in existence, and people see value in them. Like money Bitcoins are fungible meaning just like a $20 bill can be replaced with any other $20, a Bitcoin (or 1/20th or 1/50th of a Bitcoin) can be swapped out with another Bitcoin (or portion there of). Some people say Bitcoin will continue to rise in value, and become the gold standard of currencies, because unlike other paper/non-digital currencies where more bills can be printed by governments, Bitcoin has a finite number of coins that, while equal in value to each other, can not be duplicated or added to.

There are other kinds of digital assets that we will start to see emerge, and these are Non Fungible Tokens (NFT’s).

A NFT (non-fungible token) is a special cryptographically-generated token that uses blockchain technology to link with a unique digital asset that cannot be replicated. 

Non-fungible tokens differ from popular cryptocurrencies such as Ether (ETH), Bitcoin (BTC) and Monero (XMR), which are fungible; for example, you can exchange one Bitcoin for any other Bitcoin. ~ CoinMarketCap.com

One of the first popular examples of this was a craze over CryptoKitties. One-of-a-kind digital cartoon cats, that can be bred to create more new individual CryptoKitties, but no individual CryptoKitties could be duplicated. This one key thing is what makes them non-fungible, they are unique and not interchangeable. Essentially they are like an original piece of art. I can find a replication of the Mona Lisa, but there is only one original. NFT’s are each originals, and even though they are digital, they are unique and more originals can not be made… they have a specific fingerprint in a blockchain that can prove they are the original.

While CryptoKitties were a silly craze in 2017, they were also an excellent proof of concept that essentially showed that digital collectables can have and hold value, if you can prove that they are unique. NFT’s allow artists to create art that holds a digital signature to say, ‘this one is an original’. Besides art, this will be useful in:

• Gaming – imagine being able to trade a unique tool or weapon outside of an online game, without any chance that this rare object can be duplicated.

• Concert tickets – counterfeit tickets are made and sold, ripping off potential customers, but if a concert ticket is an NFT, it’s easy to confirm it is the original that you are buying.

• Identification – from credentialing to medical information, you can be in control of your own data and take it with you.

Unique digital assets are something that will have many valuable use cases and we will see them rise in popularity. And while some people will laugh and scoff at the idea of CryptoKitties of any kind holding any real value, non fungible Tokens and digital assists are something that will both hold value, and grow significantly in real use cases in the very near future.

Documenting progress through journaling

When I restarted archery last December, I was told by my coach that I should be journaling after each practice. I don’t know why, but I decided that I’d do this using pen and paper. So when I come home from practice, I open my paper notebook and I reflect and journal. Then I take a photo of this and add it to an archery album on my phone, where I also add photos of my score cards.

At Inquiry Hub we are always telling students to document their journey. For some this is a natural thing that they do, for others it’s a challenge. I remember doing a presentation at a local conference, and I took along a few soon-to-be grads from our first year with iHub grads. An educator asked one of the grads, ‘What would you tell your younger self if you were to start back at Inquiry Hub all over again. (A great question.) One of my grads said, without missing a beat. “Oh that’s easy, I’d say, ‘document, document, document’.”

This student and his twin brother had done some amazing inquiries, however they didn’t journal along the way nearly as much as they should have. For example they assembled a very finicky 3D printer, and watched many amateur user videos to trouble shoot, but they didn’t make their own videos when they came up with clever fixes and hacks. Graduating and looking back, they could see what they missed out on.

Students can learn so much from regularly reflecting on both successes and failures. So too can adults. My journal today didn’t look at the frustration I had tuning my new bow. Instead I capitalized on the idea that, while my site and rest are still off, and I’m adjusting as I go, I can still focus on my shot process and do that well.

I know that keeping a learning journal has helped me with my progress as an archer. For some reason, I also feel that literally putting ‘pen to paper’ has helped me anchor in the lessons that a digital journal wouldn’t. And yet, I tend to look at the journal more because it is also available digitally on my phone. All this to say, that as part of a learning process, reflection and journaling are very effective.

Remember that along your learning journey, it’s a good idea to journal, reflect, and document, document, document.

Broke my bow

On Thursday after work I was shooting my compound bow and stopped for the day. I decided to wax my bow strings, then on a whim thought I’d shoot one more round. With a quick mental lapse, I stood up and put my trigger onto the bow loop, drew back my string and dry shot my bow… I shot the bow without an arrow in it.

When you do that, all the energy intended to push the arrow forward gets returned to the bow. I heard a whip sound that was the volume of a firecracker at close range. Then I felt the sting on my hand. My broken bow string whipped my thumb.

I got ice on it right away, and it’s really just a surface wound, so honestly my ego hurts more. And as it turns out, my bow got hurt even more than that. I took it to the pro shop yesterday and it turns out that I damaged both cams. And unfortunately, it’s an older bow and the bottom cams are no longer available. So I need a new bow.

I’m all for learning from my mistakes, but damn this was an expensive mistake! The only saving grace is that they have a used model upgrade of my bow on sale and, while still expensive, it’s far cheaper than a new replacement of this quality. I’m told it’s a bow that’s been to the world championships, and since I know of only one left-handed shooter of that caliber around here, I think I know the previous owner, who would have treated the bow very well. Today I’m going in to try this new-to-me bow out.

I’m trying to see the silver lining and appreciate that I’m getting a bow upgrade that I probably would not have gotten for a couple more years. Something good has come from this… even if it’s a bit of a financial expense. My goal this year was to shoot at least 100 days this year and I’m way ahead of schedule, so I know I’ll be getting great use out of my new toy… and I’ll be a lot more careful about putting an arrow in it before shooting!

Sharing my posts

I had a meeting yesterday morning where we did small breakout sessions, and we discussed a topic that I’ve talked about a few times here on my Daily-Ink. I wanted to share something I wrote, but decided not to. Then we met a second time but it ended up being me and just one other colleague in the room. We continued the conversation and afterwards, I shared a link to one of the pieces I wrote via email. I got a really positive response, and I’m glad I did share it, but I’m always hesitant to do this.

It’s kind of weird, I write every day, and my post is automatically shared to Twitter, LinkedIn, and my Facebook page, so I obviously don’t mind sharing my work publicly. Yet I always feel like sharing my own writing at work is like shameless self-promotion rather than sharing my thoughts. It feels like I’m trying to show off, or that I’m bragging. Sometimes I’ll use my writing as a reference to what I say, but don’t mention the blog post or share the link.

I think that part of the challenge is that on social media people can choose to read or ignore my posts, and there is no price to pay if someone chooses to ignore the post, However, if I share it directly with someone, well then I’m kind of expecting it to be read. I’m forcing it on someone. This is me just thinking ‘out loud’ about this. I don’t think I’ll change my habits. I think I’ll continue to be overly cautious about sharing my writing in conversations with colleagues.

It’s not that I’m shy, it’s that I’m trying to be respectful. I don’t want to push my writing on people. But sometimes I articulate things better in my writing than I do trying to formulate my thoughts on the spot. I’m a slow processor, a slow thinker, and work through things better through writing than speaking.

That said, I can be quite vocal and no one has ever accused me of not participating in a discussion. Maybe that’s part of issue? I am vocal enough, and spreading or sharing my writing is just ‘over the top’. I’ve spent a few years developing my listening skills, and redirecting my thoughts to what’s being said, rather than what I want to say next. This is a skill that needs to be practiced, especially since I tend to be a lateral thinker that sees connections to things rather than seeing a single track of a conversation. So my brain wants to bounce to related things, off topic things, and maybe something I’ve previously written. But is that thing I wrote truly relevant to the conversation, or is it just relevant to me?

I don’t think I’ll share my posts at work any more than I already do after writing this. I think it’s probably a good thing that I hold back, and I’ll continue to do so.

A reset is coming

I’m not a futurist. But I see the writing on the wall:

  • Bernie Sanders and Andrew Yang put the idea of a Universal Basic Income (UBI) out in a way that has made it a serious consideration.
  • Bitcoin has gone past 50k and Tesla is leading the way in using Bitcoin the same way investors hold gold.
  • It’s clear that taxes are broken and corporations and billionaires are not taxed fairly, but there are too many loopholes to fix this any time soon.

In a short period of time we aren’t going to look at money the same way. We won’t look at the work week the same way. I don’t know what this will look like, but it will be very different… and this will happen sooner than you think.

Web advertising vs micropayments

Right now, if you do a Google search for a product like an iPhone, above the link to Apple.com you will see ads to purchase a phone. Those ads are how Google makes its money.

Meanwhile, if the search you are doing isn’t a product, but an idea or concept, then those ads aren’t always about selling something, but rather about sharing content… and that content is usually surrounded by advertising. That’s how a website gets you to look at ads on their page, how they get advertisers to pay them for views and clicks on their pages. This race for your attention is not free, and what you see on the internet, at the top of searches, and on websites next to, above and below, the content you want to see is the price we all pay… the price of our attention.

I think that there is going to be a social media platform that will show up in the next few years that is going to figure out micropayments as a means to share ad-free content. Want to see a news article with no ads? Pay 1/10th of a cent. Find a great article you really enjoyed? Give them a hand clap or two (applause of some sort), each worth 1/10th of a cent. If you really like it, you can share 10 X of your applause… or a whole penny. Enjoying some art shared or creative writing? You decide how much applause to give.

You’ll have people not paying much, but others will be generous. And along with this will come a culture of disliking sites that embed advertising. We will see a lot more ad-free content. News sites might insist on a micropayment. The challenge is how to get people to ‘buy in’ to paying rather than seeing ads. I think this will happen with a social media platform that does 2 things:

1. Charges about $10 to join.

2. Gives you 9,500 ‘points’ to give away. (10,000 times 1/10 of a cent minus a 50 cent or 500 point fee.)

Basically, you will be given the points to give away through applause for websites you like. Because these points will be called something fun besides 1/10th of a cent, and because you get so many of them, you’ll think nothing of sharing a few of them on content you like. When you run low on them, you can purchase another $5, $10, or $20 more, but with a decreasing commission:

$5 gets you 4,250 points

$10 gets you 9,500 points

$20 gets you 19,700 points

The sweet spot will be $10, which isn’t a lot of money if the points last the typical person more than a month.

Some people will use their points miserly, others will spend over $20 a month. Overall, an economy of paying, or rather ‘applauding’ content that is shred ad-free will become something people are happy to do.

It will be interesting to see how micropayments will influence the content that is shared. Will we see sites begging for applause? Viral videos earning more money than advertising could ever get them? Sites donating their applause to charity? There are many ways this format could go, but I think one thing you will see is a genuine hate for websites that share ads embedded in content… and I’m looking forward to this!

Blockchain and education

Blockchain defined: Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding). Virtually anything of value can be tracked and traded on a blockchain network… ~ IBM

One place that I see blockchain technology being used in education is credentialing. Right now a general arts degree at a good university is a credential that says, ‘I know how to study, write essays, and express my ideas’. Unlike professional programs like engineering or law or med school, a general arts degree is about building more general skills. More and more jobs are not requiring a professional focused degree, but also demand more specific skills than a general degree.

Can a potential job candidate manipulate pivot tables in Excel? Or understand the basics of coding in python? Or use a design thinking process? These questions aren’t always answered by a degree, and might be answered by a certificate. What if Microsoft or other large companies delivered skill-based credentials through online courses? What if when you received certification of completion of the course, you didn’t just get an easily copied and doctored paper certificate, you also got digital certification that could not be doctored by you, but could be verified by anyone?

Imagine having a digital portfolio that linked to all your credentials in immutable ledgers. Your skills could be verified and job descriptions could include expectations of specific skills and credentials. What do you know? What can you do?

So, maybe in the future a college degree will be less impressive than a series of verifiable skills. Maybe high school students will start getting these credentials before they graduate. To me this had a few implications to think about:

1. If we move to a more skill-based economy, how will this affect our school curriculum?

2. If credentials and credentialing become a major driver to workforce hiring, will this force more specialization in high schools?

3. Where does that leave the soft skills like communication, critical thinking, and creativity?

Some people think that credentialing like this can replace teachers, I don’t. I think teachers become more valuable. Let credential testing and digital training measure the skills that are easily measured, and let teachers loose on helping students be more creative, more entrepreneurial, and better problem solvers. Let teachers focus on helping students trying things that are epic, things that are so big they are likely to fail, and help students understand perseverance. Have teachers focus on developing communication and cooperation skills, and helping students understand the importance of learning and process.

Credentialing won’t diminish the role of the teacher, it will magnify their importance in creating leaders and problem solvers. And to me, that’s the more exciting part of being a teacher.

That unlearning thing ain’t easy

“The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.” ~ Alvin Toffler

I love this quote, it speaks to the need to embrace change, and to understand that best practice is still just practice. However as easy as it is to understand this idea, it’s much harder to acclimate to. Especially the unlearning part.

I’ve been back into archery since the winter break, got a personal best score of 280 recently, and have been able to duplicate that score a second time. (Scoring is 10 rounds of 3 arrows, with a max score of 10 points per arrow, totalling 300 for a perfect score.) However, I was using a very bad technique with my thumb squeezing the trigger rather than using backward tension on my hand and arm to trigger the release. Since trying to do this properly, I’ve been struggling more and scoring between 267 and 274.

Today I scored a 267, but I was also able to score an X-X-10 three times while practicing. I had been unable to score a perfect 30 in a round for weeks. (An ‘X’ is 10 points but also signifies that I was able to get the arrow in or on the line of the center ‘X’ ring that is the size of a penny, shooting from 18m or 20 yards away.)

While trying to work on my release these past couple weeks, my scores have been lower, and my ability to hit the ‘X’ has been infrequent. But I know that if I continue to punch the trigger with my thumb, I will not shoot nearly as high of a personal best score in the future. My trigger pulling could show some short term gains, but those gains will limit me later on. The problem is, as I unlearn doing this, my scores have gone down.

Unlearning something is hard. Right now there are many things I need to focus on, and when I’m trying to change my muscle memory, my other muscles do funny things. For instance, my bow hand has been gripping the bow tighter, rather than being relaxed, while I think about my back-tension release. And when I relax my hand after drawing, I find it hard to not relax my arm, causing me to have less tension holding my bow ‘hard against the wall’, meaning keeping pressure on the bow’s cams at the back of a full draw.

Without talking about archery technique specifically: while I focus on unlearning a bad habit, my body, accustomed to doing things wrong, doesn’t know how to put all the good moves together. Unlearning one technique means not just learning something new, but also relearning other things as they related to the old vs new learning.

This dip in my scores is part of the unlearning process, and it’s not easy to go through. When we practice new skills, we want to see a quick payoff. But sometimes we need to recognize that unlearning isn’t nearly as easy as learning, and the payoff comes from the practice itself, and not immediate progress. I can focus on my technique, and unlearning a bad habit, or I can worry about my score right now… what I can’t do is both at the same time.

Colonial noose

“New Zealand male lawmakers are no longer required to wear a necktie in parliament after the rule was dropped following a Maori MP’s protest, calling a tie a ‘colonial noose’.” (Reuters)

I’ve always hated neck ties. What kind of society are we in where we teach young boys that, to be formal, you must tie a noose around your neck and make sure it is nice and snug?

What a ridiculous fashion accessory.

I wore a tie almost every day for 2 years in China. As a principal there, it was an expectation. I wear one once every one to two months here, only when I am entering a meeting where I feel it is important to be formal, such as when I’m representing my district, or my schools in a formal way.

If I can avoid wearing a noose, I will. I know others that wear them all the time. I don’t judge them in any way, it’s fine if they want to, choose to, like to wear them. But I get no pleasure in wearing them myself. I don’t feel dressed up in them, I feel constricted. I feel like an animal in a choker collar.

The only time a tie should be worn is at a costume party when dressed up as someone from a time long past. Or maybe at a ball or Galla, like wearing a cummerbund with a tuxedo. Beyond that, I’d love to see the ‘colonial noise’ disappear from regular formal wear.
