  1. Call the support of your hardware wallet manufacturer, after all you're their customer.
  2. No, like this: https://rocksdb.org/ or https://github.com/CPPAlliance/NuDB Transactions are stored twice, the second time in a sqlite3 database named "transactions.db" to be able to have an index for various queries that would be very costly otherwise.
  3. Sounds like a slow/overloaded/failing(?) disk.
  4. What's the use case though? Trading for USD, sending, and trading for MXN. Both things that the DEX can do too, no need for XRP to be involved other than as "neutral party". I'm active in this space for 10 years by now, the "crypto markets" are exactly the thing that's holding the whole ecosystem back - just look at how exited people get if XRP gains a cent or so in value a piece or if they now can store their XRP on yet another device compared to someone writing a spec or implementation for Interledger (which doesn't require tokens to work and is the main product that Ripple is actually selling). Heck, look at how hyped people were about Codius... not because it might be a good technology, but because it has potential to increase the USD price of XRP. People in this money driven space don't want to collaborate or build, they want to earn and win. This is a doomed proposition.
  5. No, it is the inconvenient truth that people seem to ignore, especially the ones that are fixated on getting rich in USD(!) by owning/trading/"investing in"/"hodling" XRP. But hey, maybe I'm wrong - currently people at least seem far too focused on XRP and are slowly finding out that it is really hard to do anything with it if you are not trading it directly or indirectly for other money. Another major use case seems to be ogling it on a balance sheet. What do you do with your XRP?
  6. The most useless part of the ledger is XRP, since there are tons of other cryptocurrencies out there and XRP only serve a purpose as anti-spam measure on the DEX. There are better ways to combat spam out there since XRPL was started, just get rid of XRP since most people anyways seem more concerned about pricing in USD or other currencies and don't use XRP per se (e.g. ODL could perfectly work using the DEX or IOUs without ever touching XRP!). Do you even operate a full history server? I do...
  7. The 512 ledger online_delete seems very short..
  8. Write what you want to happen in a command, execute it and send the resulting text to the network which will then validate it and include it in the next ledger (usually within a few seconds).
  9. You don't need wallet software to sign and send transactions...
  10. The costs for running a validator are about in the area of a Netflix account or (if you want to do it properly and a bit more redundant etc.) about a McDonald's menu once every week. I think individuals are able to pay this out of their pocket. I have more expensive hobbies than that.
  11. You could look at the sizes of shards over time, but afaik they are storing contents compressed (also the ~13 TB are compressed, but also contain an index and probably also include the duplicated data in ledgers.db and transactions.db). There are 2 important, but different metrics at play: Growth of ledger history (all transactions and their resulting state changes) and growth of ledger state (all current objects like accounts, trust lines, offers, escrows...). Both are somewhat difficult to measure for slightly technical reasons and both have different impact on node sizing (more RAM vs. more disk).
  12. Nobody seems to actively work on it or use it for years by now.
  13. A technology that popularized a way to deploy and run software that's known as "containerization".
  14. Too much uptime! ;-) Memory usage depends a lot on how much a server is queried through the API by the way, since I guess that causes rippled to fill up its internal caches faster. The maximum amount of how these caches are filled depends on the "node_size" parameter, which internally maps to presets of couple of hidden tuneables. If you want to change these, you need to recompile (not hard, but tedious) which I needed to do for a while since a "huge" server also seemed to expect a "huge" internet connection.
  15. Why would you put a graphics card into a node dedicated to run a validator? Or do you want to run other software on there too? In that case, that's not a very secure practice, especially with a CPU that susceptible to Meltdown + Spectre. Also the specs are suspiciously consumer grade... do you run this from home? ripplenode.io likely violates the copyright on "Ripple" that Ripple Labs Inc. holds exclusively, I wouldn't recommend to do any kind of business on that page until you have a written license for that directly from them.
