leoffon Why do prime numbers make these spirals? (2019)

>all primes greater than 3 are of the form 6k+1 or 6k-1

what's the value in using this "formula"? We could also keep extending this rule, and say that all primes greater than 5 are of the form 30k±1, 30k±7, 30k±11, or 30k±13. Or go further by multiplying coefficient of X with the next primes

leoffon Show HN: IngestAI – NoCode ChatGPT-bot creator from your knowledge base in Slack

Interesting product, but it has no pricing information anywhere.

leoffon Data Classification: Does Python still have a need for class without dataclass?

For my general uses, pydantic and dataclasses are very similar, and I prefer pydantic over dataclass for the following reasons:

1. pydantic by default ignores extra fields - it's useful when I make an API call and want to extract and validate only certain fields from the response, while dataclasses throws errors if you don't specify all fields, and this behavior can't be disabled

2. pydantic is more customizable - I can overwrite the BaseModel if I have a custom need

3. pydantic seems to integrate better with python typing - I'm not sure how to explain this one, but it feels more natural and dynamic

I'm not sure what the performance concerns are, though

leoffon A formula for the nth digit of 𝜋 and 𝜋^n

since this is Python, `nth_digit_of_pi(-1)` should give us the last number of Pi.

leoffon Investigation on the effect of oral breathing on cognitive activity (2021)

Anecdotal evidence, but I've noticed how Magnus Carlsen, the current best chess player, is often mouth breathing when very focused in a game. When I was a kid I often also caught myself mouth breathing when focused on a videogame, and I think this is a common tendency for people.

I wonder if this really has a negative impact, or rather a positive one.

leoffon Pelé has died

Senna's death was sudden and a tragedy. Pelé's death is also sad, but it was foreseeable given his health condition.

leoffon It's easier and faster to pirate an e-book, than it is to buy it

I also understand this, I just wish Amazon had a shopping cart so I could use my single use card only one time.

leoffon It's easier and faster to pirate an e-book, than it is to buy it

Yes, this is correct.

leoffon Ask HN: Stripe alternative (We got blocked before starting)

Even if they unblock your account, what makes you think they won't block it again in the future?

leoffon Ask HN: What is the cheapest, easiest way to host a cronjob in 2022?

I've just created a similar setup last week: 1. Cloud function, uses Puppeteer 2. Cloud scheduler for triggering cloud function 3. Cloud storage for data persistence

Costs around 1 Euro a month, I had a similar setup for free in Heroku before.

leoffon Hetzner continues its growth in the US with a new location

You thinking this was a positive experience only makes me more concerned about your customer support.

Let's hope I don't need another "one-time" server replacement because of your faulty servers, because I already used mine. 10 hours of downtime with angry customers on my tail sounds fun.

leoffon Hetzner continues its growth in the US with a new location

Something similar happened to me. A server I have was very frequently randomly restarting, and I tried everything to solve it, i.e factory reset, reinstalling my services. I contacted customer support and they offered me to take it offline and perform some tests on it that could take more than 10 hours. After I insisted a lot, they offered me a one time server replacement, which magically fixed the restarting issue.

leoffon Where Is the AI Music?

once image models are good enough, you can train them to generate spectrograms images, and convert them back to audio to listen to the generated music.

leoffon The Secretary Problem

I've seen thousands of toilets in my life, my policy to finding a toilet in a music festival would be to choose the first one that's "good enough", no need to choose the best one.

In my point of view, this policy is more relevant if you have no prior knowledge about the subject you are evaluating. Even when choosing secretaries, how often it is that you want to find the absolute best one?

leoffon TIFU by using Stripe as a payment processor for my small business

> When I see Stripe's apology here it will not be enough for me

I'm actually just starting a business using Stripe for handling payments, and this makes me very concerned.

Is there an alternative service one could use? Is there a way not to give these shady companies power to steal all my money?

leoffon Brazilian Amazon lost 18 trees per second in 2021

losing all the trees would improve the climate? We have to pump these numbers up!

leoffon Oh Shit, Git

Isn't this what a `git reset --hard` does?

leoffon Next-generation AI models

Real programmers use punch cards for programming.

leoffon Cool desktops don’t change

But one can think of a counter example where all the new music are very high quality and will stay around for a long time (not saying this is likely to happen). Then the statement "the shorter something has been around, the shorter it will be around" is false.

leoffon Why championship chess sets are so expensive

At first I thought this was a parody like the Artisanal Firewood video (https://www.youtube.com/watch?v=TBb9O-aW4zI).

It seems like a lot of this process could and should be automated to improve consistency and quality.

leoffon AirPlay and Touch Bar = Network Disaster

I actually found it nice when using the debugger in VScode. Having the buttons for play/pause, skip line, etc make life easier.

leoffon Addressing AI’s energy cost

That's my point, you can't simply compare the energies like this.

leoffon Addressing AI’s energy cost

Following your logic, a pencil weights 0.006kg, considering E=mc*2, this is 150,000MWh. This AI uses less energy than a pencil.

leoffon What rr does

It is actually a geometric progression, so https://rrrr-project.org would be the next one.

leoffon Tell HN: Zelensky is blurring -not blanking- sensitive info in a video with Musk

I can barely count how many lines the text message has, and you think a ML tool would be able to decipher it? This is an impossible task, the text information is completely lost on the blur

leoffon A visual proof that neural nets can compute any function

Since you are nitpicking, you could well use a sinusoid activation function on the Neural Network, and reach an even smaller loss value.
