HappyRobot··on USAID's chief economist has resigned. Here's why
We disagree with how we want our taxes spent. As long as the government is paying into it, I'm not convinced you would feel any differently if it was a charity or not.

> It uses a threat of violence to siphon whatever money Congress deems appropriate away from Americans, and redirects it to whatever the executive dictates. That is not a charity.

There is no violence. Congress put aside money for USAID and organizations and other groups write grants for ways to distribute that money. Someone has to read and vet these proposals and unfortunately they are paid.

Hey, it would be great for charity to be administered for free, but personally I'm not convinced that there are enough people with free time to donate to make that work. We don't expect social workers, doctors in clinics, counselors, or numerous other aid recipients to work for free so why expect the same from the administrators?

HappyRobot··on USAID's chief economist has resigned. Here's why
They may not be more noble, but they're a necessary part for the people you describe as nobel. Charities, non-profits, and USAID workers, are there to distribute funds, do research, and audit the economic benefit of funds they are given. If a nobel person is volunteering instead of donating, it still takes individuals to coordinate and request help. If people working for non profits, charities, and aid groups quit to make money to donate, it would be harder to be nobel because there's no one who can distribute and act on the funding.
HappyRobot··on The decline of the working musician
Are musicians/bands seeing success on Patreon? Are they releasing music monthly or just using it to communicate and receive recurring support?

I try to support bands I follow as much as possible (buying merch, streaming their music, and going to shows). However the jump to a recurring subscription is a hurdle. Bands seem to still be in the record -> tour -> hiatus cycle and I imagine that needs to change if they're releasing music over the year.

HappyRobot··on Apple's bad faith 27% tax on web purchases
I can't speak to food, but 50% markup is a good rule of thumb for manufactured goods in department stores. It's a big markup, but that markup pays for distribution to individual stores, storage costs, payment processing, and all the labor to stock and provide retail assistance. In addition, the stores also need to make a profit with whatever is left over. The question with Apple is how much of that markup actually goes to labor and distribution and how much is just for profit.
HappyRobot··on Show HN: Restaurants in Peace – leave a remembrance for a closed restaurant
That potato burrito was fantastic! I wouldn't recognize that place by name, but I still remember how good that burrito was.

Kaimuki has had some great places come and go. Years ago there was a Japanese restaurant (called Restaurant Ko or Izakaya Restaurant Ko) that had a fantastic Kaiseki style menu. It was one of the best Japanese meals I've ever had.

HappyRobot··on Blameless post-mortems and a just culture (2012)
Adding to this, Rosberg took advantage of the "win as a team" culture to win his championship. He fought a psychological war with Hamilton where the team refused to take sides. It was the only way to beat Hamilton.

Mercedes had to protect themselves from this and made the smart choice in choosing Bottas as he was well known for a calm and team focused demeanor. With Bottas, Mercedes could further build the team around Hamilton without causing issues between the drivers.

It would've been really interesting to see the team structure if Rosberg returned in 2017. Mercedes dodged a bullet by getting Bottas at the right time.

HappyRobot··on Blameless post-mortems and a just culture (2012)
I believe other teams do copy this, but not in driver pairings. A different F1 example are the pit crews. There's no time or space for blame if a pit stop is messed up. In the first season, Haas has pit stop issues twice in the same race. It wasn't the mechanics that were blamed, but the team principal took it upon himself to diffuse the scenario as the team's failing. This is likely similar across all the team as any doubt or the hesitation for the mechanics would only risk additional mistakes.

Drivers will always be pitted against their teammate though. F1 is technically a team sport, but the real judgement for the drivers is how well they compare against their teammate. Each driver wants to win, that's why they compete.

HappyRobot··on Trump Tweeted a Sensitive Photo. Internet Sleuths Decoded It
One aspect of the clarity that an NPR article [0] mentioned yesterday was the sensor design and software required to take non-blurry and non-distorted images. The size of the satellite is impressive, but I didn't think about the challenges due to orbiting speed and light refraction in the stratosphere.

HappyRobot··on Raspberry Pi 4 not working with some chargers
I don't think there is any take away for consumers. This seems to be an explanation for why certain cables do not work and how to avoid this issue when designing electronics that accept USB-C power input.
HappyRobot··on Nasa captures images of supersonic shockwaves
Someone posted this [0] on an article from another website. It's NASA's method for taking these sorts of pictures from the ground. The process for taking airborne images is probably similar, but must require so much more coordination.

HappyRobot··on A Cultural History of Fat
Ready made meals are usually higher in sodium and fats than fresh cooked meals.

Edit - https://www.consumerreports.org/food-shopping/supermarket-pr... The article doesn't call out higher amounts of fat in prepared food, but does mention higher cost and added preservatives.

HappyRobot··on Why only 2% of Chinese pay any income tax
One aspect of a carbon tax (or the tax discussed in the podcast) is a steady tax increase. I guess the intended function is to have the tax revenue stay the same even with declining carbon use. Hopefully carbon tax revenue would go to zero, but I'm sure there would be other things to tax when that happens.

Initially when the parent comment mentioned the income tax, I didn't remember that it would be used to offset a carbon tax. Their point about discouraging work made sense and was the thing I remembered.

HappyRobot··on Why only 2% of Chinese pay any income tax
An episode of Planet Money[0] mentioned that some economists believe income tax is not ideal. Their thinking was that taxation usually discourages the action that is being taxed. Work shouldn't be discouraged. The proposed solution in the episode was to replace the income tax with a carbon tax. Encouraging people to cut down on their carbon footprint with taxes that wouldn't be more than their current income tax.

HappyRobot··on Hawaii Supreme Court Rules in Favor of Building Thirty Meter Telescope
For anyone interested in more information about the history and tensions behind the project, the Offshore podcast (a podcast that examines race and identity relations in Hawaii) produced very good season on the TMT[0]. Mauna Kea is sacred and the promises and ownership disputes over building on the mountain is an issue that should not be overlooked.

HappyRobot··on Bloomberg’s chip story reveals murky world of national security reporting
It might not be that simple. If the story was done properly, Bloomberg received information from a source that they were able to verify using other sources. Maybe they saw parts of the report they talk about, but likely they just talked to sources. Bloomberg likely cannot reveal anymore information without revealing sources. Their options are to stand by their story, or retract it.

I'm waiting for another news outlet to bring more information. Additional sources will come forward and more reporting on this story will only get us closer to the truth.

HappyRobot··on Amazon raises minimum wage to $15 for all US employees
> What about people who don't need a basic living wage, like students who still live with their parents? Why should they be pushed out of the market?

Part time work. You can work 15-25 hours a week at the higher minimum wage while having time to study or deal with other things. A proper minimum wage should be the amount for a worker to live on after working 40 hours a week. If an employee can not make enough to live in that area (after working for 40 hours), the employer should not be there and is taking advantage of the employees.

HappyRobot··on Taking back control of my digital life
You might be interested in the https://www.reddit.com/r/homelab subreddit. The prevailing wisdom there is to buy used enterprise hardware, install a hyperadvisor, and set up separate VM's for everything. It's easy to scale, easy to tinker with, and really flexible.
HappyRobot··on Americans are changing their relationship with Facebook
The article could be clearer, but 26% might be out of all age groups. 44% is only the people in the 18-29 age range.

I would be curious to see additional breakdowns. Sure 26% deleted the app, but are they still using messenger? How many are using a web version of Facebook or have stopped using the platform entirely?

HappyRobot··on F-35 Program Cutting Corners to “Complete” Development
Do you have a source on the F-22 variants? I thought that one of the things that locked us into the F-35 was the tear down of the F-22 production line. Can we still make F-22's?
HappyRobot··on Lego Axle Sorter [video]
This is one of my favorite videos of his. https://www.youtube.com/watch?v=oYhAKxOlfXQ All movement and actuation is powered by a single motor. The timing is synchronized through gearing and linkages. I am in awe whenever I watch it.
HappyRobot··on Project Natick – Underwater datacenter with live cameras
Yes, but we need to be careful when we discharge excess heat. The sudden addition of unnatural heat can be an issue for ocean ecosystems. https://en.wikipedia.org/wiki/Thermal_pollution
HappyRobot··on Droppers Is How Android Malware Keeps Sneaking into the Play Store
I thought Android apps were sandboxed [1]. The "needs access to my file system" is the way for data to transfer into that sandbox.

Android should add the option for temporary data access. I would prefer turning on the access temporarily to send 1 photo, then turning it off a few minutes later.

HappyRobot··on Toys ‘R’ Us Didn’t Have to Die
The article you reference blames the debt load.

> To compete, Toys R Us would have had to invest significantly in its website and stores. But the retailer was using most of its available cash to pay back its debt.

Yes, profits were falling crazily, but the company was still profitable. Without the debt load, they could've spent some time losing money while they pivot to a new business strategy. The debt load really prevented them from trying anything except surviving as long as they could.

HappyRobot··on NASA completes full-power tests of small, portable nuclear reactor
I think the drawback for space disposal is the risk of rocket failure. If a rocket explodes with nuclear waste on board, the waste would spread over a large area. It's safer at the moment to consolidate nuclear waste in small areas away from civilization.
HappyRobot··on Festo's New Bionic Robots Include Rolling Spider, Flying Fox
I think you underestimate good engineering. The Festo Smartbird is a good counter example (https://www.festo.com/group/en/cms/10238.htm). I'll agree that we still have a way to go with bipedal robots, but other biomemetric robots (Boston Dynamics) are very impressive these days.
HappyRobot··on The dirty industry of fast fashion is causing an environmental “emergency”
That price label may not fully represent the actual economic cost of the good (if the environmental impact externalities are not factored in). Factories could pay market price for all materials and labor, but cheap out on waste disposal. If that waste flows downstream and causes adverse health effects, the cost to that economy is not reflected in the clothing production. Market price for cotton could be the farmers who over farm their land. This price would not include the damage done and impact it might have on farming food years later.

You're right that we need to be fixing the issues at the level they appear, but every level is being squeezed for the best cost. It's up to the retailers, consumers, and fashion companies to place a larger value on environmental impact and pay the proper price.

HappyRobot··on It’s time to ditch SMS-based 2 Factor Auth
Your passwords and two-factor keys should not be accessible through the same service. If 1Password is hacked, both forms of authentication are compromised.
HappyRobot··on Ask HN: How is drop shipping as an alternative source of income?
Reply All has a good episode this week that discusses drop shipping. (https://www.gimletmedia.com/reply-all/117-the-worlds-most-ex...). Seems to be based on this article - https://www.theatlantic.com/technology/archive/2018/01/the-s... Basically no one really knows if there is money in drop shipping, but people are making money by teaching people about it.
HappyRobot··on How inflation swindles the equity investor (1977)
> Does a "real interest rate" per your definition actually exist?

I think the closest measure we have is the difference between the interest rates banks charge from loans compared against the "overnight rate" of interbank lending. This is controlled by the fed (through the federal funds rate) and is another control the fed has to control interest rates.

If I remember correctly, one of the hindrances for the 2008 recession recovery was that the interest rates (offered by banks) remained high as the fed lowered the federal funds rate. The goal of the rate is to control lending and in that recession it was not working.
