Show HN: Generate animated solar system timelapse videos for any date range

https://github.com/simondorfman/solar_system_live/

A fork of Solar System Live that generates animated videos showing planetary orbits over any date range. Tracks orbital statistics (how many times Earth was lapped by Mercury/Venus, or lapped outer planets) and overlays dates/ages on each frame.Example: Einstein's lifetime (1879-1955) showing 76 years of solar system evolution. Built with Python + Pillow + ffmpeg, runs locally with...

Re:Fund Solo Ethereum Validator Node with IRA on Tuesday September 19, 2023 @09:53PM (#37579523)
Good question. Rewards vary because: “Ethereum staking APR is mainly affected by the number of active validators that dilute staking rewards and by the network activity paying out more or less transaction fees, priority tips, and through MEV opportunities created.“ That quote is from this site: https://www.kiln.fi/post/pos-ethereum-staking-rewards-a-deep...

But, if I were to assume a rate of 4%, compounding monthly, for 20 years. 32 could turn into 71. I got that number using this calculator:

https://www.mathportal.org/calculators/financial-calculators...

That’s not considering gas fees for the compounding transactions though. Nor the cost of running the server. But I guess it’s a rough guess.

Learn how I used money from my retirement account to buy 32 ETH and set up a solo Ethereum validator node (a server that helps run the Ethereum blockchain and earns an ETH reward for that work).
Would you consider adding an RSS feed? I tried adding it to Feedly and it didn’t find an RSS feed.

Interesting. Instead of just using shades or green and blue, would you consider displaying numerical values too? I was confused about how close the tiles were to flipping to my color.

Side note: I’m working on a game that has some similarities that might interest you: https://simondorfman.com/volcanoes1

Trying to find more info about the creators. Looks like there is a Delaware Corp but no officers publicly listed. Hmmm. Anyone else know where to learn more about the creators?
I like this app (voice dream) for text to speech: https://apps.apple.com/us/app/voice-dream-reader/id496177674

Buy books wherever you want, then put them into voice dream to listen.

I agree, hard to find. I found this, which I think should be in the readme: https://docs.sympy.org/latest/tutorial/intro.html

Symbolic computation deals with the computation of mathematical objects symbolically. This means that the mathematical objects are represented exactly, not approximately, and mathematical expressions with unevaluated variables are left in symbolic form.

Let’s take an example...

I believe Kickstarter and Dreamhost reorganized their companies that way when it became possible.

It questions whether one should automate something that will only need to be done a few times.

Azure Data Studio (which I like for Microsoft databases) has an extension to connect to Postgres. Maybe worth trying.

Ask HN: Could we create a Tor-like system for debit/credit cards?

Idea: stop merchants from tracking all your purchases by creating something like the Tor network for credit/debit cards.Maybe it works something like this: create a co-op financial institution that issues credit/debit cards. Each time you use a card from this co-op, it runs the transaction under an alias card number. You still get charged properly on the back end, but the merchant sees a...

I'm intrigued by this setup. Do you by chance share your scripts somewhere online?

The pdf command printed a Wikipedia link to the resume page. Are you making a joke (that I’m not getting)? Or is this a bug?
Thanks for the reply.

> Sell me on why I would use your credit union. > I don't know why I should be concerned about my bank or credit union and use your credit union.

Here’s an article about how your banking data is probably being sold: [1]

Concern for privacy would be the main selling point. But it would also have to be a great banking experience too. Great website and mobile apps. And rates that beat the competition.

> Concerns about your idea: > - Banking laws / regulations are very detailed in the US don't allow for much anonymity for traditional consumer banking accounts. (there are some legal ways to do that aren't traditional consumer banking, it but it is hardly fool proof and legally complex and I'm not sure about rolling that out at scale)

It sounds like you know more about this than I do. Any resources you can direct me to so I can learn more?

> - Once you introduce a credit / debit card the privacy may be out the window as 3rd parties are involved.

I’m hoping there will be a technology solution we could develop that would make credit/debit transaction data private. Perhaps a card that generates a new credit card number for every transaction?

> - People might simply not care / will be a hard sell to get them to understand / care.

Agreed. I wanted to test the idea here because I thought HN would have more people who care about privacy.

Ask HN: Would you switch to a privacy- and security-focused credit union?

The Problem: I care about privacy and security. I live in the U.S.A. Where should I do my personal banking?The idea: Start a credit union with a focus on privacy and security. Build the credit union as a template for other credit unions to follow. Open source as much as possible.

I’d like to hear more about that project. Can you share a URL if it’s public? I’ve imagined making something like that for showing a version of a super-8 film at 18 frames per second.

This sounds great. I decided to try it out after reading about this export feature.
I think the folks who make the game modules usually ask for permission from the game designer first. I know that's what happened with the Dominant Species module. http://www.vassalengine.org/wiki/Module:Dominant_Species
