A slight over simplification, for example s&p was negative 1% per year from Jan 2000 to Dec 2009. Plus the cost of your leverage.

But the general point that US equity returns have been good and leverage would have increased them stands.

For some reason, Americans are “told” to get 4x leveraged to the real estate market but to pay for their equities with 100% cash.

Great points. It depends on how confident you are in the claim that the primary purpose was “artificially boost quarterly profits.” No particular evidence presented in the excerpt.

> For example, Gryta and Mann report that GE would sometimes artificially boost quarterly profits by selling an asset (e.g., a diesel train) to a friendly bank, knowing that it could then buy back the asset at a time of GE’s choosing.

So fraud?

You did a beautiful job and you should be proud of it. Both the information and the aesthetics are a treat.

Can I ask what technology stack you used? For the images, the animations, and the voice over?

I’d like to be able to do something like this.

Interesting point. There are obvious connections from the Yamas to the eight-fold path of Buddhism: Right View, Right Resolve, Right Speech, Right Action, Right Livelihood, Right Effort, Right Mindfulness, and Right Concentration.

I’m not aware of an explicit ordering. But the other seven steps complement and deepen the meditation.

You may be interested in Terry Tao’s polymath collaborations.

> As for upper bounds, de Bruijn showed back in 1950 that {\Lambda \leq 1/2}. The only progress since then has been the work of Ki, Kim and Lee in 2009, who improved this slightly to {\Lambda < 1/2}. The primary proposed aim of this Polymath project is to obtain further explicit improvements to the upper bound of {\Lambda}. Of course, if we could lower the upper bound all the way to zero, this would solve the Riemann hypothesis, but I do not view this as a realistic outcome of this project

To your point, there was some excitement and progress in the beginning, but it remains an unusual approach to mathematics.

Generally, if you find a simplification that makes the problem trivial you’re interpreting it wrong and should reconsider.

Re:The Deliberate Practice Guide on Wednesday June 14, 2023 @02:29PM (#36330406)
Great point.

Code review gives some commentary on result, but process wise it’s a solitary activity.

Perhaps this was some of the benefit of the mostly abandoned practice of pair programming?

Re:The Deliberate Practice Guide on Wednesday June 14, 2023 @08:43AM (#36325033)
I agree coding is a great discipline for both deep work and deliberate practice.

I would draw a distinction between the two. Deep work is about achieving the focus and attention to do serious work. Deliberate practice is about the motivation and effort to focus on improving your skill set.

You probably know this from Cal Newport’s excellent book, but for others. Two great but distinct mental tools to add to your kit.

I think your point about law breaking is good. Facebook, Uber, AirBnB. Too much law breaking in the name of innovation.

I intended to make a narrower more trivial observation that innovation produces winners and losers. Innovation is just competition.

I like your optimism.

The article points out they were previously hit a few privacy issues. There was an FTC order in 2012 which the FTC claimed Facebook violated with in months. So they got a 2019 order encouraging them to follow the 2012 order. Now this order encourages them to follow the 2019 and 2012 orders.

My personal view is these enforcements would be more effective if they hit the management of the corporations rather than the shareholders.

Probably too simplistic.

Innovation serves some and “disrupts” others.

Uber might be a handy ride for you. A NYC cabbie who is in debt for his medallion might see it the opposite.

The article disagrees. But my sense is you are right in relative terms. Much more failing than acquiring.

Article:

> Startup M&A bounced back: The number of venture-backed companies that were acquired or merged with another company increased by 20% in Q1 compared to Q4 2022, with 57% of those M&A deals valued at $10 million or less.

Most futures markets you pay both sides.

Some equity venues are pay both sides. Others are “reverse” provider pays.

> I said nothing about whether the game was or was not truly "electro-mechanical".

Indeed you did not.

Likewise no one “accused” you of that grievous transgression.

As a this is not a courtroom, perhaps it was more an observation than a charge to be defended.

Chips you say? Reminds me, chips aren’t technically electromechanical are they? No no friend, they are not! In fact, it contains 17 computers . 17 computers, but only 12k lines of source? Yes feels low,…

And so on, like a conversation? Where the contradictions are not accusation but invitation.
