Private file access between computers. Even in 2020 it appears that building a connection between machines (macOS, Linux and Windows) requires a miracle if you don't like to share everything with cloud providers. cryo file mangager is an attempt to get rid of the hassle: https://cryonet.io

Let's solve Harmony! The first scientific experiment was conducted by 5th century BC Pythagoreans. They wanted to show that the basis for musical consonance was math. From that, they inferred that harmony in math accounted for the harmony of the cosmos. This integration of math+physics was very forward thinking. But, if we fast forward to the present, we still don't have a complete scientific explanation for the basi…

I got a little lost when you tried to compare musical harmony to societal harmony.

With regards to musical harmony, is it possible that it's more or less random? I know multiple cultures have different definitions of musical harmony. I suspect the evolution of hearing also contains random elements. Similar to language, it's not so much about an inherent universality, just a universality we can all learn and agree on.

Thoughts?

Education. Schools are functionally no different from part-time prisons. You must attend daily under penalty of law. Many teachers are plain awful. They rely on students being additionally taught by their parents. That forces parents to go to school with their children, which perpetuates the vicious cycle. The teacher recalibrates the class to the students who either understood everything the first time or had supple…

I certainly agree that so much about school is problematic and could be improved, but ...

> Schools are functionally no different from part-time prisons.

A prison by definition cannot be part-time ; ). Plus, it's a totally unfair comparison. Schools are intended for everyone. Prisons are intended for a specific subset of people deemed to have broken a law.

Schools are for children. Prisons are for adults.

And so on.

I’m working on a new way to talk online, with the goal of killing cancel culture, increasing understanding, and basically calming down current radicalization. Picture Reddit, but with the ability to anonymously share ideas with other people in your social circles. My theory is that most reasonable people stay off social media, so places like Twitter end up filled with unreasonable narcissists. At the same time, discu…

I will say that I’m not really interested in talking with people I necessarily know. I want to talk to people who have well thought out arguments that are non obvious.

Take what you will from that and good luck.

I worry from this brief description that you may be ignoring cultural aspects to our perception of consonance and dissonance.

Also, harmony itself is a distinctly western concept whose musical role expanded dramatically with the advent of polyphony. Many (most!) musical cultures around the world don't give harmony much, if any role, and place higher importance on melodic structure.

Also, music harmony and the other kinds of harmony you mention seem to me to be related only by the language used for this particular metaphor. There seems to me to be no likelihood of there being any interesting relationship between musical consonsance and "harmony with technology and harmony with nature".

I want to give everyone a digital identity. In some countries (including mine) basically everyone has an e-ID which we use to sign in to things like government services, banks, payment providers and much more. This is absolutely essential to everyday life and many startups are built around it. Unfortunately, many countries don't have useful e-IDs and the ones that do are limited to that one country. I want to create…

> Does this mean that a user can use their identity on two separate sites, and those two sites can't collude to build a shared profile of the user, without the user's permission?

That's precisely what it means. User IDs will be unique for each site and I'm hoping to anonymize email addresses as well, similar to what Apple has done for "Sign in with Apple". Some companies might be required by law to collect some PII but in that case their needs will be vetted before.

> Does the user have to choose a specific server to be involved in all their identity interactions? If the server stops working, does the user lose their identity?

I'm currently building this as a centralized product so no, there is only a single server maintained by us. I'm mostly concerned with building a great product but the prospect of decentralized, verified identities is also very interesting. I'd love to see what that could look like!

> Also, is it possible to create an account without a phone (or rather without a SIM, since those are often tied to real identities)? Does your proposed system assume that people can't register multiple identities (using multiple phones) if they wanted to?

The current product is in the form of an app so you will need a phone but you won't need a phone number (or SIM). An email address is currently required though.

My current system assumes one identity per person but it's fully possible to have multiple devices which acts as that identity. This might change depending on regulation though and is not set in stone.

If you have any more questions I'd be happy to answer them!

Sounds kind of similar to Yik Yak, except using social circles instead of area? Hopefully it ends better than Yik Yak did.

Earlier quoted context omitted.

Do you expect that students will utilise the backtracking aspect of the software? I think 12 year old me would just use the solver and then log off.

I am optimistic :) The entire curriculum is extremely easy when properly explained at correct pace.

As a father with a 12 year old struggling with math, to say something is extremely easy makes me think you have a better understanding of math than people.

I hope this counts as weird enough ...

PROBLEM:

If time travelers from the future were to visit you, it would be difficult for them to quickly prove their authenticity.

SOLUTION:

Temporal passwords. At the start of each year, you devise a new password. You commit the password to memory, but you never write it down or divulge it to anyone until Dec. 31, when you submit it to the Temporal Password Registry, which publishes it and promotes its dissemination.

RESULT:

Prior to their visit, time travelers from the future can look up your temporal password in the registry for the year in which they plan to visit you. Their ability to communicate a password that you have not yet shared with anyone provides evidence that they are actually from the future.
