"what if… economics", a simple one-page economics simulator: https://whatifeconomics.com

I wanted to have a place to see the effect of changing macroeconomic factors, e.g. interest rate, inflation, unemployment, etc. It's designed to show economic relationships for non-experts.

I just submit things I find interesting and occasionally other people find it interesting too. Usually opposite to what I expected.

Not OP but I believe it’s Fugu (7B). According to [0]: “Fugu itself is a trained coordinator LLM.”

A web app (PWA) for logging tinnitus episodes - Mimi Memo: https://mimimemo.com/

Developed for my personal use but publicly available and open source. I’m pretty happy with the current state so don’t expect a lot of updates and features, but hopefully others might find it helpful.

Not quite.

- The 43% is peak drag reduction in the transition zone only, the bit between laminar and turbulent flow, not across all flight conditions.

- Aerodynamic drag is one part of fuel burn, not a 1:1 proxy. There's also engine efficiency, etc.

- This is skin friction drag on a wind tunnel model, not a full aircraft which has extra bits like windscreen wipers.

I still think it's exciting but I reckon fuel savings would amount to a few percent (aeronautical engineers, please correct me if I'm wrong).

Ménière Memo, a web app for logging and reviewing Ménière's Disease episodes:

https://menierememo.com/

Intended for an audience of one so still a bit rough around the edges, but the intended audience said “excellent” and is actually using it.

Mostly AI-built. Source code is here:

Data centers can inadvertently pollute water through chemical runoff from evaporative cooling systems, including biocides, corrosion inhibitors, and heavy metals that accumulate at scale when facilities discharge up to 5 million gallons daily.

The knot codes are beautiful but the ones in the article all seem to be repeating patterns, so I wonder if you could take a 60° slice of each one and save space without losing information.

If you're in the north of England the Derby Computer Museum is nicely maintained and presented. Exhibits are pre-2000.

Maybe a third reason:

“Last week, Trump Media, the parent company of Truth Social that is majority-owned by the president, said it was getting into the energy business, announcing a merger with a fusion firm TAE Technologies.”

Ah, sorry. I'd only searched for cryptology and should've been more thorough.

I think they meant “nigh on irreparable“.

Nicely put-together collection of tools - thanks for sharing.

Would be helpful if more input boxes could use relevant types (e.g. “number”, “url”, etc.) so the dedicated keyboard appears on mobile.

Not the OP but…

"Healthline.com provided an opt-out mechanism, but it was misconfigured and Healthline failed to test it, resulting in data being shared with third parties even after consumers elected to opt out.”

https://www.bbc.com/news/technology-65772154

"The company agreed to pay the US Federal Trade Commission (FTC) after it was accused of failing to delete Alexa recordings at the request of parents.”

https://www.mediapost.com/publications/article/405635/califo...

"According to the [California Privacy Protection] agency, Todd Snyder told website visitors they could opt out of data sharing, but didn't actually allow them to do so for 40 days in late 2023 because its opt-out mechanism was improperly configured."

He must be delighted to hear that.

Sad to not see a mention of tracking, i.e. the ability to disable open-tracking or click-tracking. Some services even have it disabled by default to respect subscribers’ privacy but sadly they weren’t included in the article. Some examples: Buttondown, Mailcoach, SendStack. No affiliation, I just researched them in the past (https://blog.daniemon.com/2022/11/15/privacy-first-newslette...)

Nice – I like this a lot. I feel like I'd use this for slow-lane reading and the original HN site when I'm in a rush.

Regarding HTML to GPT-4, I seem to remember commenters here saying they got better results by converting the HTML to Markdown first, then sending to an LLM. Might save a bit of money too.

The downside of that is screenreaders can't read them out.

This is not even scraping - it’s just crawling and indexing.

Side note: Thank you for your work! My non-technical partner was able to create and print postcards that had to be in CMYK format, thanks to Krita. You made her very happy :-)

He did try a basic control with his first version: “i got ice consistently over several nights, even though there was no frost on the ground, and pots of water sitting next to the box cooker did not freeze.”

That’s what Global Privacy Control (GPC)[0] is trying to do. So far it’s been referenced in California, Colorado and Connecticut state privacy regulations as an "opt-out preference signal” or "user-enabled universal opt-out method”[1]. Sephora paid a $1.2-million settlement in 2022 for not respecting the signal[2].
