tennien··on The effects of wealth on (Swedish) marriage and fertility
“Men still divorce their sucky wives” is a phrase you’d be comfortable with? I’m not.
tennien··on Ask HN: Why isn't there more effort to build highway-bound self-driving cars?
More fatalities happen off highways, where roads are in unusual condition and there are more edge cases.

1. Wouldn’t a 30min commute be 1/3 as worse there’s a 20-25min section you can disengage?

2. It can force reengagement via the same mechanism for L2 highway driving, but there is a period where one need not pay attention. There are also existing car lots on the sides of highways for maintenance, and they could be added and expanded. At worst, the shoulder provides space for hundreds of cars per km.

3. greifers are a problem for any self-driving system

7. The remote drivers need engage only in exceptional circumstances, as the driver would.

9-11. apply to existing geofences, but with far more added complication, including pedestrians and cyclists.

tennien··on Ask HN: Why isn't there more effort to build highway-bound self-driving cars?
That’s interesting: I’d think a 30min commute would be much better if the 20-25min could be spent disengaged.
tennien··on Ask HN: Why isn't there more effort to build highway-bound self-driving cars?
Most fatalities happen off highways, despite highways accounting for a disproportionate number of miles driven.

Accidents still happen, but it’s hard to believe they would be less safe than human drivers, when most accidents are caused by fatigue, reckless driving, illegal maneuvers, and unusual driving on the part of the operator. It’s even harder to believe that it wouldn’t become safer with effort, when both the road and the behavior of cars is far more predictable.

tennien··on Apple appears to be manipulating its own App Store ratings
Why do people still care about the App Store ecosystem?

Apple has made it profitable only for mobile games. Since 2015, 99% of large successful companies have started on web.

Based on the article, it sounds like the incumbent angered a lot of people.

The news behind the news is how somebody helped Durr win.

tennien··on Show HN: Retool – build internal tools faster
Definitely! You'll find Retool supports much more than SQL databases and Django admin supports a tiny subset of Retool use cases. For instance, most companies find that after a certain scale Django admin apps need to be converted to custom code. Retool is designed makes custom code unnecessary at any scale.

Thank you! We definitely do hear that from hardcore VB users back in the day.

That's right: react + a ton of customization

That's perfect! There's already a labelling component built-in!

Thank you! In fact, most of our enterprise customers are on-prem. Updates are distributed regularly and you've always got the choice of whether to update. Will reach out!

The frontend is standard react + redux + a lot of customization. A lot of the engineering effort is in the library of components and database connections we've built up.
tennien··on Show HN: Retool – build internal tools faster
It's true - retool can do much of what blockspring does (or blockspring might be able to be implemented in retool). But retool can do much more, writing back data and running arbitrary api endpoints. The range of frontend components you'll find in retool goes well beyond tables too - from the basics of any app (buttons, dropdowns, checkboxes) to more advanced json previewers, forms, and even image labelling.

Thank you, you should try the onboarding as well!

1. Yes! We support google and standard SSO solutions (Okta, etc.)

2. We do! Check out the charts components under "display".

3. We take security very seriously. If you want to keep security 100% in your infra, we support on-prem deployments.

This is definitely true and one of our insights as well. All you need to use retool is basic working knowledge of sql and javascript, so there's no dependence on the original author.

It's standard auth - as if you were connecting your aws server to an rds db. Once the connection is established, you can use it in any page.

Classical inheritance is rarely "an appropriate choice" but prototypal inheritance is appropriate "any time you need inheritance"? Classical inheritance is syntactic sugar for prototypal inheritance.
