Wish / ProblemWhy?

| Synchronize Postgresql databases : Imagine issuing a COPY TO query for every table in a database and then syncing the resulting CSV with other nodes. We can add a version column to every table so we avoid syncing unnecessarily. Conflict detection could be implemented by showing multiple copied and marking one as active.
0
| Eventual consistency strategies : Eventual consistency is database state that eventually looks the same everywhere. It assumes a multiple replica database. Each replica is available during a partition. So updates can occur to the same data. You need some way of resynchronizing changed that interfere with eachother
+1
| Distributed data storage : If you have many nodes and want to store data - how do you store data?

| Event sourcing and CRDTs as data storage : I think event sourcing and CRDTs can be combined to provide an alternative to the blockchain for general purpose data storage

| Database proxy : One way to get decentralisation for free is to write a Postgres database server which is a simple text based protocol and distribute the resulting queries to peers P2P

| Distributed history search : Rather than indexing the entire internet, index everybody's browsing history to find content

48 dweeks 2 dhours ago Realized proof-posting of ideas, problems, and results @ 0 > oo

People had been concerned about the preservation of authenticity, and proof of time of existence of their ideas, before the time when an insecure browser and the web could peep into.

Proof-posting works with most of the known blockchains, and you can even enter a custom blockchain of your own.

56 dweeks 2 days ago Home index cleanup @ 0 > oo

To increase the signal-to-noise ratio for first-time visitors of the home page, I have hidden menus, and compacted operations, so as to let the eyes focus on content.

However, apparently, some people didn't like it, because it is not clear what to do, so, I mostly reverted the change.

It is now possible to lock targets, create teasers for investment, and share them with potential interested parties.

58 dweeks 7 days ago I implemented column hashing @ Postgres synchronization solution

I implemented a hash that takes previous data and current column and the previous hash to produce a hash of the entire database.

This allows us to synchronize with the minimum of data transmissions when I write the synchronizer part which shall rehash all its own data, then retrieve the hash of a binary search of the sorted data.
