float4··on User Inyerface – A worst-practice UI experiment
I wasn't getting through because my domain was "domain". When I changed it to "gmail" it was fine.
float4··on The ongoing witch-hunt for sex workers in Sweden
> Nobody is getting hooked on paying people to pour concrete.

So you think sex work is illegal / made very impractical in so many countries to protect the customers?

float4··on Patent Trolling’s twin: Copyright trolling
Atrocious that such a trivial case cost you so much money that you actually lost (not strictly, but it must've felt like a loss).

My dad is currently suing has past employer (the state). It's taken two years so far and they try to screw him over in whatever way possible. Luckily the union is paying for his lawyer, so he doesn't really care.

As someone in his early twenties who knows very little about law, the way such cases go down is mind-blowing to me.

What is the roadmap for localisation? I tried some queries that should give localised results, but they yield terrible results (just like DDG does).
float4··on Amazon destroying millions of items of unsold stock in one of its UK warehouses
This has been known for years, at least in Europe. German article from 2018: https://www.wiwo.de/unternehmen/handel/das-ist-ein-riesengro...

Edit: people replying seem to think that I'm saying that:

1. only Amazon does this; 2. it can be prevented but Amazon just chooses not to.

I didn't say any of those things.

float4··on Amazon destroying millions of items of unsold stock in one of its UK warehouses
A lot of products are returned in used state, or have very slight use marks like scratches, tiny dents, protective foil that's been removed, etc. These items therefore can't be resold as new. Finding out exactly which items are and are not good enough is expensive, and therefore the items are just discarded.
float4··on What's Inside the EU Green Pass QR Code?
There's the privacy-utility tradeoff in data anonymisation, but most algorithms focus primarily on privacy. There usually are no parameters that promise any kind of utility, only parameters that promise privacy.

In this case it looks like they want a guarantee on both, which makes sense.

(So yeah, you're right, this definitely isn't just k-anonymity)

float4··on What's Inside the EU Green Pass QR Code?
> By default this means the day and month of birth and your initials, unless you share those among many other citizens. In that case, more data may be added

This sounds like k-anonymity, in which case the k is usually made public. Any idea what value they chose?

float4··on Git undo: We can do better
> novice users are terrified of it. When they make a mistake, many would rather delete and re-clone the repository than try to fix it

In my experience most beginners use a GUI like Atlassian Sourcetree or the Github desktop client. It's a lot harder to make mistakes using the GUI in my experience.

I still really like this idea though; eventually a subset of the beginners wants to learn the git cli and that sure seems scary at first.

float4··on Don’t Worry about CO2, Worry about the Earth’s ‘Energy Balance’
> even the best parents can have horrible kids

I agree completely, but my statement doesn't contradict yours.

I said: bad parent implies bad child. You say: good parent does not imply good child. These statements do not contradict each other.

Having that said, my initial statement is still flawed, as there are very nice children that have pretty awful parents. Probably because of reasons you outlined (peer group etc.)

float4··on Don’t Worry about CO2, Worry about the Earth’s ‘Energy Balance’
- "Don't worry about bugs, worry about your program crashing."

- "Don't worry about extreme weight gain, worry about cardiovascular disease."

- "Don't worry about your bad parenting skills, worry about your child being a brat."

float4··on Show HN: I made a community sourced fitness routine database
I see this criticism often, but the program focuses a lot on proper form, starting with relatively light weights, and only increasing weights when you can complete all sets, so I don't really agree with it.

However, I do agree that if you want to get just a bit more in shape, a simpler program without barbell compounds is a better choice. I was assuming that the grandparent wanted to get into weightlifting, as most people in my age group mean that when they talk about wanting to get fitter.

> The secret is to show up. Every day. Just keep stacking those good days.

This is just not true. The most popular beginner weight lifting programs are comprised of ~3 workouts a week of ~30-60 minutes each. There's a reason for that. Exercising every day sure sounds nice, but it increases the chance of injury and often is too great a commitment for people with a sedentary lifestyle.

> Most programs get repetitive after 6-8 weeks anyway

You can easily follow a beginner program for many months before linear progression stops. Switching programs after 6-8 weeks as a newbie is absolutely pointless when you do compound exercises.

> (It’s also much easier said than done)

Yeah, it is when you force yourself to work out every day. 3 days a week though? Far more manageable.

float4··on Show HN: I made a community sourced fitness routine database
I'll make it simple for you: do Starting Strength. Three 45 minute workouts per week, 3 exercises per workout (you have to do all 3 of them, so no choices to make here).

There's a reason why this is, by far, the most popular choice for beginner weight lifters.

float4··on Show HN: I made a community sourced fitness routine database
Virtually everyone will tell you to just do Starting Strength or Stronglifts 5x5. Both are fine, both require 3 workouts a week of ~45 minutes each.

If you're willing to monitor your diet a bit and stick to the program, then you'll truly see amazing gains in a year.

That tweet is three months old. No way YC bans someone over a three month old tweet (unless they only discovered the tweet recently, which I doubt).

I'm betting there's more to this story.

Needless to say that I do believe in your friend's expertise and intentions. I only posted this to show how impossible it is for normal consumers like myself to assess sunscreen quality.

float4··on Master List of Logical Fallacies (2018)
Three things that helped my reasoning skills and rationality:

- programming / applied maths;

- being forced to memorise ~20 logical fallacies in high school;

- growing the hell up and learning that being right just doesn't matter.

The third point was the most important. As a child / teenager, I always wanted to win discussions. Even if I knew I was wrong, I'd use every trick in the book to try and win an argument nonetheless. Then, I started studying computer science and I met a lot of highly neurotic people who wanted to be right no matter what. I obviously found them extremely annoying before I realised I was in fact one of them.

The very words you use ("You see the many flaws of the enemy camp and don't see as many in your own") are the ones I now try to avoid at all times, because viewing the other as the enemy is what really messed up my reasoning skills.

Learning to treat a discussion as a genuine learning opportunity has been a huge blessing for me.

float4··on AirPods Max and AirPods Pro Don't Support Apple Music Lossless, Apple Confirms
Apple lossless goes up to 24bits at 192KHz, which is over 4mbps. I believe bluetooth 5.x only supports 2mbps, although I'm not sure.

According to wikipedia, Apple did file a patent in 2019 for high bandwidth low latency audio streaming over bluetooth (up to 8mbps)[0]. Looks like they've been working on this for a while.

float4··on Why do older individuals have greater control of their feelings?
> If you were just getting too mad at stuff they got therapy for that

CBT being the most popular kind. In CBT you detect negative emotional reasoning, categorise it, and refute it by coming up with a more rational response.

See the pattern?

float4··on Pandora says laboratory-made diamonds are forever
> Also I feel like most women want it, because it's what everyone asks of them.

To me it feels more like a classic case of mimetism: all beautiful / successful / happy / rich people have a diamond ring, so most women naturally want one too. It's not really about fear, but more about a strong desire to have the same object as your role models.
