An Obsidian user on Medium recently lost an entire vault to data corruption because of an encryption plugin.

I’m very sorry this happened to them, and that they didn’t have a backup.

Truly, if our notes in Obsidian can’t function without features that exist only in that app, we’ve shackled ourselves to the wall of a prison without a door.

Always have an exit plan! Always backup your work! And never lock all your data with a key you don’t own.

@ellane help me see how this is better than OS filesystem level encryption?

@EpiphanicSynchronicity @kepano @ellane

How would Obsidian avoid the lost key problem the original person had?

I’ve done cryptography work in the past and I avoid using it like the plague. Many users put too much trust in the wrong places

@ellane I can't see how the encrypted notes are a good idea.

  • Nosey partner? Lock the device with a much better password. Or find a relationship based on trust.

FWIW my wife has my 1PW master password.

Today's life lesson, cryptography is very hard. Most people shouldn't use it outside of the OS level stuff.

@EpiphanicSynchronicity @ellane

Password manager of course. They do cryptography for a living.

I don’t I use any other locked files on my computer

Fibre installed to replace Bell. I should celebrating, instead my WiFi performance is noticeably worse around the whole house. Ex my office used to get ping: 4ms, 600Mbps down and 500Mbs up. Now I get 8, 300 and 158. The Adorn 854v6 modem isn't delivering a fraction of what it should.

Make it reversible, when we make it possible for someone to back out of something we're increasing the . The Agile community seems to have this one down pat. We tend to call it an experiment. We ask could we try this as an experiment for 4-6 weeks and gather data on the outcomes?

10,000 Hrs of Practice will make you...

I call this the Malcolm Gladwell myth, since it his book the popularized and distorted already questionable research.

As usual, I'm not a psychologist. I don't have a PhD in any science. I do coach Agile and Scrum. I also explode the balloons I call NeuroMyths. As a general rule, if Gladwell writes about it, tread carefully.

In "Outliers", Gladwell suggests that completing 10,000 hrs in their chosen discipline will excel.

Some of the problems:

  • The original study was about deliberate practice with the intention of improving performance, with focus and feedback. Without deliberate intention and feedback, we might be experiencing the same HOUR over and over again, repeating the same mistakes.
  • 10,000hrs was just a catchy number in the original paper by Anders Ericsson, it wasn't magically. If was an average then Gladwell missed that the group would be spread to either side of that number

  • The students in the study were already exceptionally good violinists. This was about going from exceptionally good to world class.
  • It was a narrow study, in a small area, not a good source for a generalist book

Others have shown since:

  • Deliberate practice works well in fields with stability where the rules don't change often: chess, classical music, tennis etc. In areas where the landscape is changing then deliberate practice

A meta analysis: https://artscimedia.case.edu/wp-content/uploads/sites/141/2016/09/14214856/Macnamara-Moreau-Hambrick-2016.pdf suggests that in chess it predicts 26% of performance; 21% for music and 18% for sports.

Other factors that maybe as or more important?

  • Genetics I should have picked better parents
  • Age when you started My hockey career is over

Another research group studying how long it takes chess players to achieve "master" status found it ranged from 728 to 16,120 hours

Reduce Upfront Costs, is one way to improve . I found it interesting to learn, people value a savings of $5.99 with free shipping, over a $10 discount on the product itself. Free shipping resolved uncertainty, where a discount for even more money does not.

I guess I'm an odd duck, I look at the total cost of ownership

when circumstances are uncertain our brains press pause. An experiment that Berger cites: students were offered a cheap vacation and placed in three groups: pass, fail and unknown. The pass and fail groups both wanted the vacation. The uncertain group didn't want the vacation as much. Yet eventually they will either be in the pass or fail group, so their interests should be the same. The Uncertainty caused them to press pause.

I couldn’t get an iPad Pro long enough in advance to publish a review today.

Instead, I finally took the time to prepare something else: a comprehensive story about all the problems of iPadOS.

"The fraud of the cryptocurrency bubble was far more pervasive than the fraud in the dotcom bubble, so much so that without the fraud, there’s almost nothing left. A few programmers were trained in Rust, a very secure programming language that is broadly applicable elsewhere. But otherwise, the residue from crypto is a lot of bad digital art and worse Austrian economics."

Everett Rogers - Diffusions of Innovation - one of the most cited science books ever. It's the source of Innovators, Early Adopters, Early Majority, ...

In this book Everett, that up to 87% of the variance in adoption of an innovation (idea or product) comes from the trialability. Trialability is an odd, word. It just means if our ideas can't be easily tried. They will be ignored.

Next time you want an improvement at work make it sure it can be tried easily.

"When people are treated unfairly, for example, when they are not allowed to have input into decisions that will affect them, or when they are not given good explanations of why certain decisions were made, the symbolic message may be that the organization does not think highly enough of them (to provide input or to be given good explanations)."

mlevison,
@mlevison@agilealliance.social avatar

@grimalkina sounds interesting. Is there a way to access without the paywall?

mlevison,
@mlevison@agilealliance.social avatar

@grimalkina Thanks.

That's strange. I would always be happier to see a link to something that isn't paywalled.

I see the value of Doi link.

Heck occasionally, failing all other options I fallback to sci.hub.

The quotes strike as very interesting since they also tie in very well the SCARF Motivational model: https://agilepainrelief.com/glossary/scarf-model (Not a DOI link).

People pushback when treated unfairly.

- How much would you pay for $50 gift card at a local retailer that must used in two weeks. On average people were willing to pay $45. Now offer a lottery ticket with 50% chance of winning a $50 and 50% chance of winning $100 Gift card. We would expect the perceived value to go up or stay the same. In fact it dropped to $16.

To reduce the at work, offer experiments and make bigger decisions reversible.
