spiralcoaster··on Show HN: I made a heatmap of 3400 VCs who are open to cold emails
You have some kind of bias in the dataset or the visualization. It's showing places in "Boston" to be south east of the city in a completely different location.

spiralcoaster··on There is minimal downside to switching to open models
This can't be for real.

The title asserts there is minimal downside to switching to open models, but the article provides zero evidence that this is true, and the author hasn't even attempted it yet. The end of the article states "I’m hoping it’s going to be minimal".

I wonder if I can get a post to the front page with the title: "There are no real barriers to humans colonizing Mars next month". And at the end, "I'm hoping there are no real challenges."

spiralcoaster··on Show HN: I rebuilt the only parts of my IDE I use, in Rust, over a weekend
Actual title: I had Claude code up a diff tool in Rust over the weekend

My guess is this made it to the front page solely from the Rust boost.

spiralcoaster··on Why I'm Forced to Say Farewell: Google Management Has Lost Its Moral Compass
Right, because I'm sure that's not what he's been doing this entire time. Everyone knows Google has been a shining beacon of goodwill since 2017.

spiralcoaster··on Waymo Premier
So what you're saying is this hypothetically disabled person who is physically incapable of driving chose NOT to mention that, but instead chose to provide "I never got my drivers license" as their reason?

And you're asking someone to consider this because I presume you think this is a likely enough scenario to consider?

spiralcoaster··on Show HN: Gitdot – A better GitHub. Open-source, written in Rust
We shouldn't trust the new project. Right from [1] you linked to:

> The problems I kept running into:

> - I'm lazy.

That should tell you all you need to know about this super hype new fantastic GitHub written in Rust ! ! ! !

spiralcoaster··on It's Not Just X. It's Y
I thought I was the only one that did this. Double stay away if at the end you find out it was "made with love"
spiralcoaster··on Creatine raises brain energy levels and slows cognitive decline: study
Don't waste your time responding to people like this. Their post is not much more than a passing thought where they take the headline fully at face value, and therefore are convinced it must be worth something and we should continue to study it. They will never read the paper or have a critical thought of their own.
spiralcoaster··on Citing 'severe' math deficits, UC faculty demand a return to SAT tests for STEM
Now imagine a significant portion of your students are missing the prerequisites.

Do you really think these professors are up in arms about a few students who don't have the prereqs? It obviously must be a large enough proportion to worry about.

It's no longer "if a student somehow makes it into my class", it's "many students are currently making it into my class"

spiralcoaster··on Coding on Paper
What difference does it make if they heard of it, or how rare displays are vs pen/paper coding? I imagine most everyone at this point has heard of e-paper and e-ink displays, but the author clearly dropped the "e" to make it sound more intriguing.

Would you be asking the same question for a post titled "Drawing with Ink", but it linked you to a page about drawing with an e-ink display? Of course not. It's misleading.

spiralcoaster··on Googlebook
What's funny is that these days if I see a Google product that I'm even remotely interested in, I just immediately write it off because I know it's something they will kill in a very short time frame.

It's just never worth the hassle of buying/using a Google product. Never.

spiralcoaster··on I let AI build a tool to help me figure out what was waking me up at night
This is the most HN thing ever. Someone works to create an ultimately useless tool because no matter what you find the answer to be, the solution is the same:

-- Attenuate loud noises --

Which is exactly what they ended up doing

> With actual data, I could finally act with some confidence instead of guessing:

> I added proper acoustic panels (the IKEA ones for offices to create meeting areas work surprisingly well)

> I added extra insulation around the bedroom door and the window (silicone, rubber, ...)

spiralcoaster··on OpenAI’s o1 correctly diagnosed 67% of ER patients vs. 50-55% by triage doctors
Maybe you had trouble re-reading your own comment but I can tell by how you responded here (a cascade of links/references) and a snarky comment ("I can keep going if you'd like") that I'm sure the doctor was glad to be rid of you.

You didn't say the doctor disputed you had a fever. You said the doctor told you the fever wasn't concern until 100.4. Which I'm guessing is your fault for misinterpreting. If you google around, it's very easy to see the fever thresholds.

Here, I'll even paste a summary for you, and I can keep going if you like:

Key Temperature Thresholds

- 100.4°F : The standard definition of a fever.

- 103°F : Contact a healthcare provider

- 104°F : Seek medical attention, particularly if it does not come down with - treatment.

- 105°F : Emergency; seek immediate care.

In one of your own links (clevelandclinic.org), here's an excerpt for you:

When should a fever be treated by a healthcare provider? In adults, fevers less than 103 degrees F (39.4 degrees C) typically aren’t dangerous and aren’t a cause for concern. If your fever rises above that level, make a call to your healthcare provider for treatment.

spiralcoaster··on I bought Friendster for $30k – Here's what I'm doing with it
I love that you're looking to "spawn some special relationships" but are unwilling to ask for a name/number. There's no app in the world that will stop you from "wishing" you took action in getting some girls number.

spiralcoaster··on Show HN: Brutalist Concrete Laptop Stand (2024)
I guess "I poured some concrete into a mold and put a power outlet in it" wouldn't be as eye catching of a title.

This is one of those things where someone does something incredibly simple, but dresses it up in pretty language and even some totally irrelevant chemistry equations (because they r so smrt) to make it look like more than it is. Which LLM did you paste the equation from?

And of course those who also have no idea how anything is made are unbelievably impressed. You can tell by the amount of exclamation points in all of the toxically positive reactions. Good work in that respect!

But hey, I guess it's not another vibe coded project with an LLM writeup. Progress.

spiralcoaster··on Artemis II is not safe to fly
Right, so let's add more risk by flying side by side with some nutjob with no regard for their own life. Sounds reasonable.
spiralcoaster··on LLMs predict my coffee
It absolutely does. The model that came closest simply used that model twice in the same equation. One for the cup and one for the air.
spiralcoaster··on LLMs predict my coffee
Is this for real?

This is like someone with no background in physics or engineering wondering "can a LLM predict the trajectory of my golf ball". They then pontificate about how absolutely complex all of the interacting phenomenon must be! What if there was wind? I didn't tell it what elevation I was at! How could it know the air density!? What if the golf ball wasn't a perfect sphere!!? O M G

And then being amazed when it gets the generic shape of a ballistic curve subject to air resistance.

This speaks far more to the ignorance of the author than something mind boggling about the LLM.

spiralcoaster··on I love my dumb watches
> I also find the reasoning in "Why track your sleep at all? If you’ve had a crap night, you’ll wake up tired." weird. That's the equivalent of saying "Why track your blood pressure at all? If you've had a problem with high blood pressure, you'll wake up with a stroke." Not that the sleep tracking on smartwatches seems to be worth much but I just don't agree with the logic.

Equating tracking sleep to tracking a diagnosed and dangerous medical condition seems ridiculous. Not even remotely equivalent. There are lots of things in life that aren't worth the effort of tracking. There was a recent post here about a guy who spent years meticulously tracking every aspect of his life so he could crunch all the data and learn something interesting about himself. He learned in the end that he learned nothing new worth knowing.

"Why track your tumor at all? If the tumor becomes malignant, you'll wake up dead". That must be equivalent too right?

spiralcoaster··on ArXiv declares independence from Cornell
You're right. The name is just classic gatekeeping and elitist, clearly. I am 100% certain that's why they chose it. If they really cared about inclusion, they would have called it research.io

I hope they ramp up their blocking of AI access. The last thing we need is providers like this getting hammered by AI
spiralcoaster··on GPT-5.4
This is the low quality reddit-style garbage that gets upvoted on HN these days?

spiralcoaster··on What does " 2>&1 " mean?
Who do you imagine the users were back when it was being developed?
spiralcoaster··on What does " 2>&1 " mean?
Yeah but now they're using npm to install a million packages to do things like tell if a number is greater than 10000. The chances of the programmer wanting to understand the underlying system they are using is essentially nil.
spiralcoaster··on I don't know how you get here from “predict the next word”
Two very big revelations here that I would love to know more about:

1. Can you reveal "what's actually happening behind the scenes" beyond the hint you gave? I can't figure it out.

2. Can you explain how an ants sense of smell leads to anthills?
