mdavis6890··on Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid
I'll agree with other commenters that actually just showing a complete solution is better. Or both!
mdavis6890··on Information Camouflage
I wish people would take this into consideration when naming their company/product/etc. At least drop a vowel or add a silent 'h' or something...
mdavis6890··on It’s time to leave the leap second in the past
I’m reminded of the most excellent write-up on qntm.org about abolishing time zones. If you haven’t read it, and you’re one of those kinds of folks (I was!) this will quickly sober you up :-)

mdavis6890··on Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid
- All sections must be connected into a single, contiguous network. - The whole network is contained in the grid, and no pipes may run outside the grid. - Bulb-shaped pipes with a single connection are terminations (dead-ends).
mdavis6890··on Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid
Great game!

I humbly suggest that you flesh out the rules just a bit more. I struggled to figure out if pipes were allowed to run out of bounds, whether they all had to be connected into a single network, and the significance of the bulb-ended ones. I'm not totally dense and could make some guesses, but this still made the puzzle less than approachable for me at first. Basically I just guessed at these things, tried to see if I could solve one, and once I did and saw my complete solution all was clear. But why not state these things up front? Or maybe that's part of the puzzle? :-)

My first solve took 9min, then 3, then 1.5min for my third.

mdavis6890··on America’s favorite family outings are increasingly out of reach
Things, including economic things, always change over time. The mix of goods and services that we produce will change, and prices with them. Many things will get more expensive or become unavailable, while other things will get cheaper and more plentiful. And new things will be invented.

Televisions and microwaves are cheaper now. Intuitively I would have thought cars are cheaper too - but a moment of research indicated they're actually more expensive. Food and energy have become much cheaper as well. (Talking about over decades)

It's very easy to cherry-pick any one thing to focus on and say "Look how bad/good it is now." - but that doesn't make it meaningful or right to do so.

mdavis6890··on Inflation Has Outpaced Wage Growth. Now It’s Cutting into Spending
It must!

For obvious, numerous reasons we are producing less stuff now than before, so we have less available to consume.

Prices must outpace wages, or we get empty shelves, or we can ration. But we MUST consume less on average.

We could talk about taking from the rich, but actually the rich don’t consume all that much in aggregate, so that doesn’t help much (wealth and income don’t matter for this purpose, only consumption).

Yes that’s reserved for the government only.

mdavis6890··on Domino's spent $50.4M on TV ads to brag about $100k donation
Also the online ordering infrastructure that has to be developed and maintained is run (and paid for) by corporate - not the franchisees (I assume). This makes the online ordering system essentially it's own business that must provide it's own value to get paid.

The price of the pizza goes to the restaurants, the delivery fee goes to the driver (mostly, I hope), and the "online convenience fee" goes to the business running the online ordering system. It all works out.

mdavis6890··on Domino's spent $50.4M on TV ads to brag about $100k donation
I think a more genuine headline would be "Domino's spent $50.4 million (and counting) on TV ads [that] brag about [their franchisees] giving local businesses a total of $100,000"

Clearly they're going to spend money on advertising anyway. And it's not unreasonable for those advertisements to include things they are proud of, such as when their franchisees support local businesses. They clearly say "Domino's franchisees" in the ad.

mdavis6890··on Number of pubs in England and Wales falls to record low
We should impose mandatory-minimums for alcohol consumption. I think 10 drinks/wk should do it.
mdavis6890··on Why Devs Can't Sell
Actually I think open source supports the author's point. Lots of open source projects are cool. Not very many make money. In fact sitting here I can't even think of one. Okay, Red Hat made money for a while.
mdavis6890··on Tell HN: Brother printers now locking out non-OEM paraphernalia
An alternative viewpoint is that this business model is good for consumers, or a least differently neutral.

If printer companies try to make their money on the printer sale, then it's very difficult for folks who only need to print a little now and again, and they might not be able to afford a very good printer. By moving to a consumption-based revenue model, now they can let everyone have a super-cheap printer (they are MUCH cheaper than decades ago, despite inflation), and then the people who use the printer more (get more value from it) pay more, and those who don't pay less.

This seems reasonable, even though I also don't like hardware that bricks itself if I don't use as directed.

mdavis6890··on Supreme Court Overturns Roe vs. Wade
Article the twelfth (AKA the 10th amendment) of the Bill of Rights from the US Constitution: "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.”

So the current argument might be that since the constitution does not give the federal government the power to regular abortions (or to prevent states from regulating them), then that power to regulate them or not is reserved for the states to do as they please.

The prior argument (from Roe vs Wade) is that the US Constitution provides a right to privacy and that prohibiting or otherwise restricting abortions violates that right to privacy.

While there's no explicit right to privacy in the constitution, it could be implied by the 14th amendment: "... nor shall any State deprive any person of life, liberty, or property, without due process of law ..."

From the original Roe vs Wade opinion: "A person may choose to have an abortion until a fetus becomes viable, based on the right to privacy contained in the Due Process Clause of the Fourteenth Amendment. Viability means the ability to live outside the womb, which usually happens between 24 and 28 weeks after conception." https://supreme.justia.com/cases/federal/us/410/113/

mdavis6890··on Ask HN: Has anyone made any serious money selling Android apps?
Probably the friction scales more with transaction count than overall cost, so you're getting at a real issue. It would be a pain as a vendor to deal with a zillion little one-cent transactions.

Still I think there are workarounds: Maybe I can pay Apple $20/mo for 2000 'points' that I spend on whatever subscriptions I want, and they pass the points/payments along in bulk to each vendor. Not sure.

mdavis6890··on Ask HN: Has anyone made any serious money selling Android apps?
You're describing the way software used to be sold, and that worked fine since really there was very little that needed to be patched over time. It wasn't connected to anything. There was no internet and barely a network. It ran on one specific OS/version that was expected to remain static over years. And app compatibility largely fell on the OS vendor anyway. If your app broke with a new version it was their fault.

Things have changed now.

"paid app at version X, which will get bugfixes indefinitely" - Would you continue maintaining some old version of an app you wrote three years ago that nobody buys anymore? I certainly hope not.

mdavis6890··on What will a Chromium-only Web look like?
Basically - the web is what Chromium source code says it is - no more, no less, and no other.
mdavis6890··on Chasing utopian energy: How I wasted 20 years of my life
I think you're missing the fact that solar and wind, being quite mature and otherwise unencumbered, have been pretty well optimized to what physics and chemistry will allow. Further gains will be slow and incremental.

Nuclear has been around quite a while as well, but is heavily encumbered by public sentiment, sub-optimal regulations, and knowledge atrophy. There is much more room for optimization before running into physical laws.

mdavis6890··on Ask HN: Has anyone made any serious money selling Android apps?
I really want an app-store filter for paid/free apps, where I can filter OUT the free apps. Anyone else?

I feel like a big part of the problem is that the entire space is filled with junky 'free' apps, and getting to something high-quality is difficult. And so we're trained not to value apps because they're awful, and therefore not worth paying for anyway. A vicious cycle.

If the apps are reasonable quality and solve a problem, what's $5 or even $10? Many people spend around that for a cup of coffee that will be gone in 30min. I'd happily pay that for a good app - if only I could find one.

I'd LOVE to see super-cheap subscriptions too - like maybe ten cents or even less per month. This solves another issue: Once a dev has gotten most of the one-off sales they can, there's not much incentive to maintain the app. A subscription model is much better for this, but for most simple utility apps it needs to be very cheap.

mdavis6890··on Affordable housing in California now routinely tops $1M per apartment to build
People want to move to population centers - but many (not all) people in population centers would rather they didn't. So they make it hard to build.
mdavis6890··on Affordable housing in California now routinely tops $1M per apartment to build
Everybody wants "affordable housing" - but many do not want more people. This is the fundamental disconnect. Many folks just do not want to make it any easier for more people to move in. They would like rents/prices to be lower though.

This is how we end up with rent control and tight building restrictions - because it solves both problems. Roll up the drawbridge against new people by blocking development, but then make the housing affordable by fiat.

The only remaining problem then is 10 year waitlists to get into one of those rent controlled spaces. Bummer on that...

mdavis6890··on Affordable housing in California now routinely tops $1M per apartment to build
They'd probably rent for $3k month. With no water.
mdavis6890··on Ask HN: Having trouble getting senior applicants, wondering what to do about it
Sounds like you're underpaid ;-)
mdavis6890··on Ask HN: Having trouble getting senior applicants, wondering what to do about it
This seems weird to me. I hear it all the time, but I don't understand. It's a few hours, even as much as a day of effort - to make a huge jump that might be worth hundreds of thousands of Dollars, or perhaps have other major lifestyle improvements. And "if I can get a similarly..." - sure, but is it not worth a few hours up front to find the best job for you? I would happily to 4 hours of work to get a 1% better job.

Of course, if it's STEP 1, and you're faced with many iterations of this, that's a different story. But if I'm somewhat certain that I'm looking at a great offer from a great company at some point, why not spend the 4 hours?

mdavis6890··on Ask HN: Having trouble getting senior applicants, wondering what to do about it
Public company stock should be valued near it's current market value, minus a bit to account for volatility. I would think 90-95% is about right.
mdavis6890··on Webcams aren't good enough
The supply and demand curves for high quality webcams do not intersect.

There is no price/quantity combination that will satisfy both producers and consumers.

mdavis6890··on Patreon cuts deep inside creators’ pockets
Still, why is a percentage more fair? What definition of 'fair' are you using?

"If people think Patreon is making a killing with their fee structure, they should build a competitor." >> Yes! And honestly this could be applied in so many places where people like to complain, and yet nobody builds a competitor, or they do and it ends up looking like the original. So easy to complain, so hard to do better.

It's all about the conflict of interest created by having prisons earning money by having prisoners.
mdavis6890··on US prison workers produce $11B worth of goods and services for little to no pay
The problem is the conflict of interest that it creates.
