@DC8
Does your account include a public key? Lompsa desktop should include that automatically otherwise include on the command line (only needed once).
Just tried leasing to that account and it seemed to work on http://lompsa.com

Yes, has public key. Lompsa also doesn't show my balance, at least on that page on that picture.

Tuli mieleen kun kokeillut tuota "multi account" juttua ja toisen tilin perustin niin voiko kummankin tilin laittaa saldon vuokralle ja vaikka eri pooliin ?

lisätty; Nopeata vastausta ei tullut... ei auta kun kokeilla. Katsotaan saanko jotain sekaisin.

lisätty 9.1; Tähän mennessä toiminut ok

The problem occurred again. Several times.. I had a blank space in the end of my passphrase which I copy+paste into lompsa.

I noticed the typo. :) Occasionally I didn't copy the blank space in the end and occasionally did, so I thought there was some problem with Lompsa. But it was just me opening the wrong wallet.

The proxy server for all thin clients, and the one serving Lompsa.com blockchain content is currently offline.

Full nodes work normally. Experimental backup web access is usually available at https://wallet.fimk.fi:7886

Hasn't been down.

That is... At least I could not see any automatic server restarts.
Probably a fork that got resolved, lots of blocks are popped and downloaded which blocks access to the db from the server app, that could take a few seconds.

The mysql replicated database that we've been running on testnet is meant to separate the (sometimes) blocking blockchain operations and the user facing web software which should of course never block.

A few seconds up to a minute cutoffs are usual. Now the proxy server was inaccessible for at least 20 minutes, but full nodes worked fine. This indicates a problem with the web proxy, not blockchain?

There is no proxy server actually.

lompsa.com connects over websockets directly to a FIMK instance we have on our server.

If for some reason the FIMK server is caught in a long and blocking process (of which there are plenty, just the nature of how  crypto/blockchains - especially NXT/FIMK - 2.0s - operate) you will experience that as a non-responding website.

The most time the FIMK server blocks is on updating database indexes, of which there are again plenty.
Too much actually if you'd ask me.

But there is another dilemma to be solved first. NXT/FIMK are first in it's kind as compared to BTC where there is a user facing API that is much and much more complex than BTC's.

We have all sorts of database indexes to be able to have our client be responsive, while for BTC there only are a handful of indexes (they have no accounts, ae, dgs, aliases, all-sorts-of-searches etc) we have a multitude.

I believe in order to scale this has to change in two phases.

First phase is well on it's way as you know, here we've integrated the FIMK server blockchain download/upload/pop/push etc mechanism with an external database, in our case MySQL.
This MySQL database now holds a one-to-one real-time replica of the blockchain, this database includes all unconfirmed transactions.

The MySQL database is a multi-threaded powerful db solution which is suitable for use as a data backend for an internet facing server. You don't have to expect down time from that.

The second phase is to get rid of all the functionality exposed directly by the FIMK server that is not essential for it's p2p operations, the API size has really gone too far imo. When this is done we would have thrown out probably half of all code and we are able to drop many database indexes no longer in need of updating.



This of course has an effect on how individual people run their own FIMK server, while running the server itself remains fully possible of course, you can run it forge etc.. But what has to change is that you can no longer connect your client to your locally running server and expect your client to keep working the same way..

When the worst internal database indexes are dropped you can no longer use the backend as is without also running the replicated database, since only the replicated database will have all the (and much better performing mind you) search/indexes.

But since probably 99.99% of all FIMK users will be coming through one of our web portals I dont think thats a problem.

To still allow people to program against FIMK we of course must publish a powerful API from our webportals, one I believe will work much better than running your local FIMK server. As you know we have made big steps in that area when we've created our server framework (based on non-blocking Play!/Scala and which works with FIMK at tha java level) .

TL;DR;

Bitcoin is relatively simple, it lacks most features of 2.0 coins.
Thats partially why it runs so well under high usage,  we call that lightweight.

FIMK has many more features and because of that it runs less 'light'.
In order to even the game we must move away non-essential functionality from the FIMK core.

So instead of having a sub-optimal API and badly performing database, what we want is a powerful and fast operating core and instead of a sub-optimal badly performing embedded H2 database we want a powerful multi-threaded and non blocking database, not affected by large blockchain reorgs or scans or whatever.

Miten tuota asset exchangea on tarkoitus käyttää? Koitin ostaa fitcoinin julkaisemia btc assetteja painamalla "buy" ko. assetin sivulla. Tämä avaa "buy asset" popupin/ikkunan missä on oston tiedot detaljeina. Ikkunan alasivussa on painikkeet "pay now" ja "cancel" Kuitenkin vain cancelia voi painaa. Mitä teen väärin? Olen kirjautunut passphrasella lompsaan ja sivun vasemmassa ylänurkassa näkyy tilinumeroni sekä balanssi.
