01:50 <stellar-slack> <sacarlson> dam I thought I fixed this problem in ruby /home/sacarlson/.bundle/gems/stellar-base-0.7.0/lib/stellar/key_pair.rb:90:in `sign': no private key (RuntimeError). can't you generate an unsigned transaction envelope? I think my original fix only provided me a way to create unsigned tx not all the way to envelope

02:03 <stellar-slack> <sacarlson> oh I guess the work around would be to just sign it with an invalid keyset for this account, I'm guessing even if you have some invalid signatures in the envelopes list it would be ok, as long as enuf valid sigs are added later the tranasction should still work. but we will have to try to verify this fact.

08:41 <stellar-slack> <bartek> Transaction envelope can have no signatures. So simply don't sign it at all.

09:18 <stellar-slack> <sacarlson> that might work in js but not sure the same in ruby. but I think this work around might work ok

09:20 <stellar-slack> <sacarlson> but I will also try that

09:52 <stellar-slack> <scott> @sacarlson: presently if you want to create an unsigned envelope, use:

09:52 <stellar-slack> <scott> ```

09:52 <stellar-slack> <scott> Stellar::TransactionEnvelope.new({ :signatures => [], :tx => tx })

09:52 <stellar-slack> <scott> (assuming you’ve got a `Stellar::Transaction` at the variable `tx`)

09:53 <stellar-slack> <sacarlson> I could try that, just provide an empty array?

09:54 <stellar-slack> <scott> yep, it should work just fine, and I’ll work up a patch to ruby-stellar-base that allows `to_envelope` to work without providing keypairs

09:55 <stellar-slack> <sacarlson> oh well it has to be in ruby as that's what I wrote this in not js

09:56 <stellar-slack> <scott> I am referring to ruby

09:56 <stellar-slack> <sacarlson> ok

10:07 <stellar-slack> <raymens> @scott how's the horizon-importer -> horizon migration going?

10:08 <stellar-slack> <scott> I’ll actually be working on it a bunch over the next two weeks. Sorry about the delay, I was working on an integration for a gateway

10:09 <stellar-slack> <scott> I hope to have it complete before I leave Nigeria

10:10 <stellar-slack> <cyberomin> Welcome to Nigeria @scott

10:11 <stellar-slack> <scott> Thanks @cyberomin I’m really glad to be here

10:12 <stellar-slack> <raymens> ok great :)

14:12 <stellar-slack> <raymens> @scott is there any PR or fork/branch to follow your progress?

14:16 <stellar-slack> <scott> @raymens: The first of the code is here: https://github.com/stellar/horizon/pull/235

14:16 <stellar-slack> <scott> (that’s just the schema management)

14:16 <stellar-slack> <scott> I’ve not pushed any code related to the importer proper, but I’ll do that when I’ve got a little bit more progress

15:38 <moo-_-> is there any toy exchange to test public trading for my tokens?

15:41 <stellar-slack> <scott> moo-_-: I’m not quite sure what you’re asking. Are you asking about the asset trading within the stellar network? If so, the network _is_ the exchange… anyone can post an offer to trade as a normal transaction.

15:41 <moo-_-> stellar-slack: exactly

15:41 <moo-_-> I am on unfamiliar waters here

15:41 <moo-_-> sorry scott

15:42 <stellar-slack> <scott> no worries :)

15:42 <moo-_-> my question is more along lines is there existing (web) services where you can try this out

15:43 <stellar-slack> <scott> Ah. I’ve not seen any for the new network yet.

15:43 <stellar-slack> <scott> You can, however, test things easy-ish using code

15:44 <stellar-slack> <scott> iris is presently working on a tool (We call it the laboratory) that will enable exactly what you’re asking though

15:45 <moo-_-> perfect

15:46 <stellar-slack> <scott> The basics are here: https://www.stellar.org/laboratory/ We just haven’t implemented the trading operations yet

16:03 <moo-_-> scott: I think it's enough in this point if I can see my offers

16:06 <stellar-slack> <brian.ebert> Was there a change to test net during the last few days?

20:38 <stellar-slack> <eva> Hey all, for the network explorer tool (https://stellar.github.io/network-explorer/) how are secret keys handled/stored?

20:40 <stellar-slack> <bartek> local storage https://developer.mozilla.org/en/docs/Web/API/Window/localStorage

20:41 <stellar-slack> <eva> thanks bartek :)

20:41 <stellar-slack> <eva> cc @john ^^

20:51 <stellar-slack> <john> @bartek: So local storage (like sessionStorage) gets cleared when the browsing session ends. Correct?

20:52 <stellar-slack> <bartek> "localStorage has no expiration time"

20:53 <stellar-slack> <eva> @bartek: I think John wants to know specifically about the security implications of the storage - can you say a little about that?

20:59 <stellar-slack> <bartek> local storage is more secure that cookies (it's not transmitted anywhere via http protocol). this probably can be changed to session storage but imho network explorer was designed to be a debug/playground tool (not a wallet) so it woudn't be really usable if keypairs were removed every time a user closes a browser :)

21:03 <stellar-slack> <john> I got you bartek! Thanks for your time, much appreciated.

21:03 <stellar-slack> <bartek> :thumbsup:

22:05 <stellar-slack> <jed> that network-explorer is deprecated though. It will be replaced by the laboratory soon
