tompetry··on Potato paradox
This is true in limited cases. Changes in bond values in relation to interest rate changes is much more involved than this. The first derivative is known as "duration" while the second derivative is known as "convexity". The size and timing of payments will vary from bond to bond, which heavily affects interest rate risk:

tompetry··on US housing market hit a ‘significant slowdown’ in recent weeks, Redfin CEO says
To be fair, Redfin is a technology focused MLS member and agency, not just a listings aggregation app. You're entitled to your opinion if you don't think that is interesting or unique, but their offering is far more than just a website and app. Interesting data on their agent stats and comp here: https://www.redfin.com/blog/2018/01/how-much-do-redfin-agent...
tompetry··on MoviePass couldn’t afford to pay for movie tickets on Thursday
I think the subscription model for theatres makes a lot of sense for all involved. Getting more people to the theatres (where they buy other stuff) and creating larger audiences who didn't previously visit theatres. The pricing and terms of MoviePass are unsustainable, but I think there will be more subscriptions for theatres that are tried.
tompetry··on Facebook Q1 2018 Earnings Slides [pdf]
I read it that way as well, was going to comment that yes quarterly earning were down from Q4, but year over year Q1 is up a lot. Sliding uphill...
tompetry··on Tesla issues strongest statement yet blaming driver for deadly crash
I don't get it. Doesn't autopilot mean that the car is steering itself? "Perfect" or not, if the car is steering itself, what is the point of having your hands on the wheel? I get the point about being alert, and needing to take over if you see an issue, but I would fear that I'd be overcompensating autopilot by having my hands on the wheel while cruising along.

Can somebody explain?

tompetry··on Growing a company that sells miniature construction supplies to $17k a month
Grew up a huge lego fan. I sent this link around my office, wondering if anybody else would think it was as interesting as I did. Everybody is now buzzing with cinder block mania, with no prior cinder block / brick laying experience :)
tompetry··on Lottery winner asking a judge to let her keep the cash and remain anonymous
I understand the desire to be anonymous, but things like this get out. While taking this route might benefit future winners, it will likely make her own situation worse via the "Streisand effect": https://en.wikipedia.org/wiki/Streisand_effect
tompetry··on Amazon, Berkshire, JPMorgan to Create Healthcare Company
I am continually surprised with the focus on attacking the "packaging" of healthcare at the insurance / network / reimbursement level. That isn't the problem that needs to be solved. The problem with healthcare costs is that there is a lack of competition of costly services provided by large hospital and clinics. In many areas, there is a single provider that runs unchecked. Two factors limiting competition are:

1) Huge barriers to entry. How do you start a new hospital or sizable clinic? Regulation, costs, training, etc make it prohibitively difficult 2) Science/data isn't good enough yet. There is not sufficient data to show which providers (hospitals/clinics/treatments) are better than others, enough to allow disruptive entrants into the system.

Only breakthroughs in biotechnology that displace incumbents in healthcare services will move the need. Re-shuffling the insurance / network / payment deck of cards aren't enough.

tompetry··on Ask HN: At what point did you incorporate for your startup or side project?
From what I remember, in order to sign a lease for the solo office I was using, the property manager required payment from a business banking account (not an individual) and to have incorporation documents. It was at that point that I incorporated.

It's not Coinbase's job to come up with the name and symbol for coins.
tompetry··on Martin Shkreli is found guilty of securities fraud
Didn't think of it this way. So true.
tompetry··on Ask HN: My company has been acquired and I'm kicked out. What should I do now?
I am beginning year 4 as a co-founder of a startup. I know how tough it can be, and how it can feel when you don't accomplish what you set out to.

People seem to be keep saying that you shouldn't get down on yourself. While true in the long term, it's perfectly normal to feel down sometimes. You've been through a lot. It's OK to feel fear and anxiety, and even question yourself at times. So long as you realize that it's temporary. Because you will bounce back. The fear and anxiety make it so, because it motives us. You are tough and determined, or you wouldn't have lasted anywhere close to this point. Respect!

Another thing to consider is.. what is your end goal? Is it to constantly be challenged? Is it loving to start from scratch and build something with a small team? If so, take a break, and try again. You aren't even 30. If your end goal is a slower pace and more financial stability, because you think long term that is what you will want, take a role at an established company. Your experience and determination as an entrepreneur will be sought after. And you can always do side projects.

Lastly, keep in mind why you took the risks in the first place. If you didn't try, you wouldn't have been happy. It's ok to feel what you feel. Take some time to rest and re-charge. You'll be back :)

tompetry··on American society increasingly mistakes intelligence for human worth
I remember being tauntingly called "College boy" senior year by a few classmates. Small town, lots of poverty, majority of my classmates never studied past high school. I didn't react much to it; I felt sorry for them, really. They came from homes that not only didn't stress the value of education, but resented it. And that was the atmosphere these kids grew up in... for the first 18 years of their lives! Every time I think of that I appreciate the fact I had parents who told me I could do anything, if I just prepared myself in school. I wish every young person had that kind of support :/
tompetry··on In poor neighborhoods, McDonald’s have become de-facto community centers
> When I was a kid, my dad would take me to the local McDonalds to do math, several times a week. They'd let us sit there ordering nothing but sodas in a comfy booth for hours. These are some of my fondest childhood memories.

This made me smile, as my dad and I did the exact same thing. He would get coffee and I would get eggs and hashbrowns before we set out on the days errands, and I remember doing long division problems with crayons for fun. I hadn't thought of those days in a very long time, thank you :)
