ttcbj··on Flutter: UI platform designed for ambient computing
+1 for flutter being really fun to work with. Its the most fun I have ever had working on mobile.
ttcbj··on S&P 500 Buybacks Now Outpace All R&D Spending in the US
Most securities have a real intrinsic value that can be calculated the future cash flows to owners from that security. For bonds, the number of variables in this calculation makes this easier to understand: If you have a bond that will pay you $100 one time in one year, then the intrinsic value of that bond is slightly less than $100 (because there is risk you won't be repaid, there is inflation, and there is a cost to waiting to get your $100). If you pay $50 for it, you are getting a very good deal relative to intrinsic value, and if you pay $150, you are getting a bad deal.

This same calculation can be made for stocks based on their dividends and any terminal value from an eventual acquisition. These calculations fluctuate more because dividends are variable.

The parent's comment is right though, its something buffet often observes: If a company buys back stock far about its intrinsic value, it is transferring wealth from current shareholders to now ex-shareholders. If it buys it back below intrinsic value, then it is transferring it from now ex-shareholders to shareholders.

There is actually a wonderful story that illustrates this. Try searching for "buffet pritzker Rockwood & Co arbitrage".

The short version is that Rockwood & Co was sitting on a massive supply of very valuable chocolate, and its stock price didn't reflect the value of that chocolate. Pritzker controlled the company, and announced it would redeem shares for chocolate (a buy-back in chocolate). Arbitrage traders then bought up shares at the low price, redeemed them for more valuable chocolate, and pocketed the difference.

BUT, what they didn't calculate was that the amount of chocolate that remained inside the company was far larger than the amount that was going out to the departing shareholders. Essentially, the chocolate 'payments' for stocks were far below the intrinsic value of the company. So, every time an arbitrage trader traded in shares for chocolate (at a profit to them) Pritzker was actually getting far richer by retaining his remaining shares. Everyone was winning, but Pritzker was winning far more. In the end, Pritzker retained a much higher ownership percentage of an only slightly smaller stockpile of very valuable chocolate, and made a lot doing it.

I think I saw the full version of this story in the biography of Buffet, but I am not sure. It is super fun. It illustrates why a management team that is buying back shares below intrinsic value is helping the remaining owners increase their wealth, and vice versa.

ttcbj··on Tesla Cybertruck
I am not sure if this will become a status symbol, but I 100% agree that that is the market it is going for.

I know three people who own a pickup (one in commercial construction, one who is a big animal vet, and one who has a horse farm). This does not appear to be designed for those people at all.

However, I think it could appeal to the same people who wanted a hummer. Driving it is just overtly confrontational. It will be fascinating to see whether there is a market for exactly this though, because Tesla is supposed to be environmentally friendly, and the people who bought hummers clearly didn't care about that (at the time, at least).

ttcbj··on U of Chicago projected to be the first U.S. university to cost $100k per year
For those interested in background on this, Paul Tough's 'The Years that Matter Most'[1] has a lot of really interesting, surprising facts about college admissions.

Many of the ideas touched on in the comments here so far are covered in much more detail in that book. One interesting fact is that although there is a lot of publicity from colleges about reaching out to lower income students, there are massive incentives (often necessities) for admissions offices to take less qualified kids who can pay full price.

Overall, I found the book a nuanced and surprising view of the realities of trying to manage college admissions, and of trying to deal with inequality in access to higher education.

ttcbj··on We are leaving the Apple App Store and all its problems
Agreed, but are Tim Cook and the board really satisfied with that? If so, it's a tragedy that so many resources are controlled by leaders who don't really care that much.
ttcbj··on We are leaving the Apple App Store and all its problems
I really wonder where Apple and specifically Tim Cook is in all this. I feel like I see posts on HN almost daily that would warrant one of Jeff Bezos's famous 'question mark emails'[1] from Tim Cook to someone within Apple. But I see no evidence of this. I see no evidence of panic within apple that they have lost the ability to delight customers and anticipate their needs effectively.

How often do I see a similar level customer or developer pain (anguish really, from supportive customers) regarding Amazon? How often do I see it regarding Google? All these companies have so many resources, but Apple is the only one that doesn't seem to be able to convert those resources into customer focus. It's painful to watch. Where is Apple's board? It's really discouraging!

ttcbj··on Broken
As another person whose livelihood is tied up in the use of OS X, I agree that apple continues to drop the ball. Hardware, software, 'security', cloud services. It's just painful. I don't understand why a company with so many resources cannot produce better results. I really love the mac, and so many Apple products, but I fear that the long term trend is downwards, and I see no sign of it abating.
ttcbj··on Exotic Physics Phenomenon Involving Time Reversal Observed for First Time
Brian Greene's 'Fabric of the Cosmos'[1] has some great explanations of space and time and their relationship.

If you are very interested, I highly recommend Carlo Rovelli's 'The Order of Time.'[2]

And 'Your Brain is a Time Machine'[3], though I ultimately found it unsatisfying, goes directly at the apparent contradiction between our sense of the 'flow' of time, and the implications of general relativity. Although it doesn't have an answer, it states the problem clearly, and has a lot of other interesting facts about our perceptions of time.

Rovelli has also given some interesting talks on YouTube.

ttcbj··on College, Calculus, and the Problem with the SAT
Well, this vs. the parent comment is the true crux of the matter. Is college more about signaling, or is it more about giving people valuable skills? I agree Caplan makes a very compelling case for signaling, based primarily on the observable behavior of people in the system.

My pet educational reform is not 'free college for everyone', but rather that the gov't would pay out a percentage of the increase in W2 earnings before/after the education to the educational institution for a few years. The gov't would pay it, so it is not indentured servitude.

In order to get paid, the institutions would need to raise the W2 earnings of people who attended. I'd also like to see a requirement that the payouts be publicly reported, so that reports could identify which institutions were high achieving in this regard.

I personally think that reform might focus the system more on improved skills, and less on signaling and a fight for improved US news rankings.

ttcbj··on Stripe Corporate Card
Well, 2% on some things + 1% on everything else is better than I am getting with Amex now. Plus, $50k in free processing is like $1,450 in free money.

Honestly, I wouldn't believe that deal, except that I have a multi-year history with stripe as our CC processor and it has been nothing but positive and as-promised.

So, I submitted an application. It sounds like a great deal to me.

ttcbj··on Launch HN: Lofty AI (YC S19) – Real estate investment with alternative data
This is the first time I have ever seen an early stage company include Saint Louis in anything, so, thanks for that ;-).

That said, you say your market is:

"Lofty AI is best for people who are: 1. Thinking of buying their first home, but are nervous about losing money. 2. Looking for higher returns than normal by buying properties in an appreciating neighborhood early."

1. I wonder if people who know they have to sell in the next three years, but don't want to sell today (e.g. a work move) are also a target market. If I know my job is going to move me in 2 years, I might like to use your service to retain 80% of the upside, but insure against downside when I sell.

2. I once read a book about real-estate investing, which said that the real way you make money is to buy rental properties with poor cash flow, 'fixup' the tenants to improve the cash flow, and then sell, repeatedly. I wonder if your appreciation-potential-evaluation/downside-insurance model applied to rental properties for sale, combined with coaching/tools for aspiring landlords, might be attractive.

It seems like right now, you are primarily using the purchaser as a source of capital, and other comments are saying "why don't you just raise the money yourself?", but if you were also using the purchaser as more like a franchisee, someone who is actively working to improve the cashflow of the property by upgrading the tenants with your (automated) advice, that might create a more interesting relationship where you have more room to add value (its more complex to analyze multi-tenant rentals, its more complex to choose high-potential landlord partners, etc).

Random thoughts. It's a very interesting idea, very original.

ttcbj··on Launch HN: Simmer (YC W19) – Reviews for Delivery Dishes
I was able to find that with your instructions. However, I would not have discovered that on my own. I went to "Nearby", it said "Looks like there are no dishes near you, we have launched..."

If you think having new users organically add dishes is useful, I might just put a big "Review a dish anywhere" button in place of that message. I didn't realize that you had restaurants in there outside launch cities, so I just gave up. If the button had been there, and I could have discovered that I could review a dish at the restaurant I went to, I would have.

Maybe it isn't realistic to expect organic growth outside of launch cities. Still, right now the search functionality seems very prominent, but the add a review functionality does not.

ttcbj··on Launch HN: Simmer (YC W19) – Reviews for Delivery Dishes
I was prepared to dismiss this, but I actually think this is a great idea as a consumer. When I eat out, or get takeout, I want something delicious. We can go to a well-reviewed yelp restaurant, but I still don't know what's good there (I often look in the 'frequent mentions' area, but its hit-or-miss).

It might also help me with my tendency to always order the same thing once I find something I like. And, it might motivate me to try new restaurants, if I had a specific compelling thing I was going to order.

Unfortunately, I am not in your initial markets, and we never use delivery services (we go out or pick it up ourselves), but I do like the concept.

If there was a way to a review a meal at an arbitrary restaurant, I would have done so tonight.

ttcbj··on You can now use YC's Startup School directory to find a cofounder
The answer, as with all things in starting a business, is that you have to make wise decisions that yield good results. Seriously.

If you choose a great co-founder with complementary skills and personality, it will drive you forward. If you choose poorly, you would have been better off staying single. The only thing that is really going to matter is your specific results. There is no reason for there to be a general rule that applies to everyone.

ttcbj··on How I Taught My Kid to Read
My wife and I (mainly my wife) used the book mentioned in the article [1] to teach both our kids (now 5 and 7) to read prior to their entry to kindergarten.

I cannot recommend it highly enough. It is so intelligently organized, each day building on the last. If you just read the intro chapter on amazon, you will see how clearly they thought it through

That said:

1. While teaching kids to read is good, I think the real goal should be teaching them to _love_ reading. My son is now a voracious reader, and both kids love books. The techniques we used to make this book fun include:

A. Finding something the kid really loves (e.g. tickles for my son, 'squeeze hugs' for my daughter), and pairing it with each lesson. Every lesson ended with a giant tickle or a set of squeeze hugs. You would think the kids would get sick of this, but ours didn't.

B. Massive positive verbal reinforcement. Excitement, joy, at the reading, amazement, wonder, etc.

C. Regular rewards, including little ribbons every 10 lessons, dinners out, and a huge celebration when they hit 100. Every 20-30 lessons we would do something crazy/unexpected, like rolling out a cake for breakfast (That was just fun, kids love a surprise cake for breakfast).

2. Our kids are very intelligent, but both hit a wall around 30 lessons. I think they were both about 4.5 years at the time. The book says any kid over 4 can run right through the lessons, but I don't know. For both kids, when we sensed they were hitting a wall, we decided to declare victory. We had a big celebration, and told them to book said we had reached a stopping point. Then we returned to it 6-12 months later and picked up where we left off. At that point, we sailed though the rest of the lessons.

All this said, having watched my son, I think the best thing you can do for your kid is make reading fun. The only way to develop a deep vocabulary is by reading massive amounts, and you cannot force a kid to do that.

So, as awesome as this book is, and as amazing as it was to participate in the process as a parent, the number one thing to do is not make reading stressful/negative. Kids will learn eventually, they don't need to learn early. The reason to take control of the process as a parent is to ensure that the experience is positive/filled with joy.

ttcbj··on Employee activism in tech stops short of organizing unions
Interestingly, for my Dad's business (employs between 100 and 300 people) the cost of worker's comp insurance is the main driver of safety. Accidents/injuries drive up your workers comp costs.

His company employs one full time person whose job is to improve safety. The guy runs safety competitions (days without a serious accident) with prizes, does reviews, researches equipment and practices, etc.

He will also tell you that the biggest safety improvement they ever made was drug testing. He resisted it for a long time because he feared it would be difficult to hire people, but after they did it he became a big advocate of it.

ttcbj··on Employee activism in tech stops short of organizing unions
True, but one difference is that the market for carpentry talent is local. So, a company that is supporting a union in city X has a reasonable expectation of benefiting from its training.

With remote work, computer science is much more global, so someone could easily be trained by a union and then go work for a company that doesn't support the union.

Interestingly, this is one of my Dad's main complaints about unions these days: That our city trains great carpenters, but then they are recruited away to non-union areas.

ttcbj··on Employee activism in tech stops short of organizing unions
My Dad owns a construction company in a highly unionized region. He is an advocate for unions, although he acknowledges that quality varies among them. That said, many of the conditions where unions are beneficial don't seem to apply in tech:

* Vocational training: unions in our area run schools to train craftsman (e.g. carpenters). This increases productivity and screens for quality.

* Shifting workforce: Construction companies expand/contract as they get big jobs. The union is a clearinghouse that enables tradespeople to switch between companies as they expand/contract. The union also helps by running benefit programs that travel with the workers.

* Commodity-ish labor: Most carpenters have about the same productivity, so it makes sense to negotiate their compensation in bulk. Unions don't work as well when productivity/value varies greatly between workers.

I also worked as an apprentice carpenter for several summers during college. I wouldn't say that the carpenters I worked with had a glowing view of the union. They seemed suspicious that the union reps were corrupt, and talked about how they would "shut down the job" over minor union infractions. They also believed the "hall" was corrupt/political in how it matched carpenters who were out of work to jobs. Several were also contemptuous of what they saw as the union discouraging hard work (if you were working hard, you were "ruining the job.")

The main point I am trying to make is that unions are complex from both the employer and employee side.

ttcbj··on How to Be a Stoic (2016)
I agree, I got a lot of value from this book.
ttcbj··on 1500 Private Jets Fly to Davos for Climate Talks
Exactly this! There was a good TED talk by Hans Rosling saying, basically, people in developing economies want washing machines (just like you).

That is why I suspect the only solutions to climate change are:

* Develop an energy source which has a lower-cost and equal practicality to carbon-emitting sources, or

* Find a way to mitigate the effects of carbon emissions.

Otherwise, conservation in rich countries is just going to be replaced by consumption of the now cheaper oil/coal in developing ones.

I don't think it is realistic to ask people with far fewer conveniences (washing machines) to abandon their hopes of a better life by conserving (if people won't give up private jets, can you really expect much poorer people to give up more necessary conveniences?)

ttcbj··on Are We in the Middle of a Programming Bubble?
I think there are a number of caveats to this article:

1. The amount that a company can sustainably pay you is dependent on how much value your efforts have in its industry. Software has significantly higher margins than medicine, law, or almost anything else. As long as those margins are sustained, it is possible to pay high salaries. (As buffet says: I'd rather work for a mediocre company in a great industry than a great company in a mediocre industry).

2. But companies don't want to pay high salaries, so they will look for substitutes. Substitutes could be technology (RDS instead of DBAs) or increased supply of quality programmers. So far, it seems like these big companies haven't been able to find good enough substitutes to force down wages.

3. If you are looking at FAANG salaries, you are looking at the top of the income spectrum. The top of the income spectrum for lawyers and doctors is quite high.

4. Market economies reward value (outcomes) not merit (hard work). Hard work is correlated with outcomes, but it is not always a perfect correlation. So, looking at programming and saying it is less 'hard' than law or medicine doesn't say much, the question is how much value the person can generate, and how much of it the company can capture.

ttcbj··on What I learned from reading a thousand emergency room bills
For the record, this is exactly how I feel. They did it to themselves. I really believe in free markets, and I really see the downsides of gov't intervention, but my direct experience with this particular market says we'd be better off with the gov't.
ttcbj··on What I learned from reading a thousand emergency room bills
My wife is a pediatrician at a large research university/med school. She is totally uninvolved in billing. She has no idea how much anything costs. She is aware of it as an issue, but its a giant organization, and the reality is she isn't going to try to fight the power.

Personally, I don't think doctors are the answer. I used to really like the idea of high-deductible. But eventually, I just came around to the idea that only the gov't can fix it (with lots of tradeoffs in that fix, obviously).

ttcbj··on What I learned from reading a thousand emergency room bills
I was not an advocate for gov't health care, but I am now for the same reason you stated. I have a high deductible plan, and have tried to get quotes in advance, but never can. I have been ripped off multiple times, despite trying to do my research, etc.

My wife is a doctor, and at this point, I think single-payer is the least bad option.

ttcbj··on Ask HN: Advice/Feedback on Hour of Code for Small Groups Grades 1-4?
Thanks for your feedback. I agree that it may be too much, but I am also reluctant to fall back to a gamified computer activity. I am going to see what the teacher thinks, but I will definitely take your comments to heart. My experience with cub scouts is that it is easy to overestimate how much complexity kids can handle in an activity.
ttcbj··on Ask HN: Advice/Feedback on Hour of Code for Small Groups Grades 1-4?
Thanks, I had never heard of REPL. Great idea. In the unlikely event and of the older kids want to play with the language at home, its also nice that they can just find it on the web.
ttcbj··on Launch HN: Station (YC W18) – One place for all your web apps
Thanks, I just tried adding two apps (our internal one, and bank-of-america small business login page).
ttcbj··on Launch HN: Station (YC W18) – One place for all your web apps
I downloaded this app, and really like it. Its a simple concept, but it would be really useful for me. That said, in order for it to be useful I need to be able to add an internal administrative app which I use frequently (its just a website). If I could just do that, it would be really useful as-is.

Ideally, I'd also like to add an internal electron-based web app that runs only on my machine as well, though that is lower priority than the standard web app.

ttcbj··on How a Website Exploited Amazon S3 to Outrank Everyone on Google
Yes, I think it is honey.

You are right that it isn't that much effort to try it. I find it annoying because they never seem to work for me. In a world where our behavior is closely tracked, I have come to wonder if the coupons don't work for me because some algorithm has figured out that I don't care.

Which actually takes things full circle from the original comment I was responding to: I wonder if online coupons are now so sophisticated that they can _only_ be offered to the price sensitive. If so, I suspect even more strongly that they are still a good/relevant marketing strategy.

ttcbj··on How a Website Exploited Amazon S3 to Outrank Everyone on Google
The comment I was responding to was implying that coupons were an outdated marketing strategy. I was saying that I think it can help companies achieve higher margins by selling at higher prices to wealthier customers, while still achieving sales at lower (but still profitable) prices with less wealthy customers.

I wasn't making any comment on the social good of price discrimination. I agree with you that some pricing strategies (buying in bulk, buying without loans/interest, rewards cards, etc) may tend to reward the wealthy. But that wasn't related to the point I was trying to make. I was trying to say that coupons seem like they could still be a useful marketing strategy for improving companies average margins per sale.
