Greetings **\** 2. Brief review of what's been completed since the previous meeting **\** 3. Code + ticket discussion / Q & A **\** 4. Any additional meeting items **\** 5. Confirm next meeting date/time **\** 1. **\** Hello **\ {-olark}** greetings **\** 'Hola' as hyc would say right now **\ [endogenic]** Hi! **\ {-guzzi}** hi **\ [i2p-relay] {-ArticMine}** Hi **\** 2. Brief review of what's been completed since the previous meeting **\** Our last meeting was on November 27th, 2016 so, nothing can be "brief" about a review. **\** There were holidays, etc, so there was a leave of absence but development is going strong. **\** All I can say is if anyone is really interested, we have git-log and github (kovri + meta), my fork, and https://forum.getmonero.org/9/work-in-progress/86967/anonimal-s-kovri-full-time-development-funding-thread for any TL;DR **\** I'm also have uncommitted work, finishing up the crypto impl refactor + testing for this new exception dispatcher. **\** JFTR: of the thousands of lines of code that we forked from, almost none of it handled exceptions. All this spaghetti code, and that guy did not even have a basic grasp of design with exception handling in mind. Literally, much of the core code is still stringed together with the hope that it won't fail. I hate it. It's always been like walking on glass, but a real fix will take time. So, I've started in **\** that direction at least in terms of getting exceptions handled or handled better. **\** We have two new contributors: MoroccanMalinois and Chris Barry (lazygravy), and EinMbyte and olark have returned. **\** At this point I think a Q&A for "brief review" would be best. **\** that summary is pretty scary **\** lol **\** Good scary, I hope? **\** ;) **\** :) **\** it points in a good direction **\** Good, I hope so! **\** sounds like bytecoin code :D **\ {-olark}** The i2pd situation was interesting to say the least :p **\** Or more aptly titled: "why2pd". **\ [endogenic]** Total kovri noob here. Not looked at the code yet. Is there any significant future use case for kovri libraries? Is it worth doing upfront? *sits back down* **\** Monero. That's the biggest future use-case so far. **\ {-olark}** I would like to see a future where kovri would be the go to i2p router for implementing into applications **\ {-olark}** Instead of tor **\ {-olark}** blegh **\ {-olark}** Monero obviously first though ;) **\** makes sense. tor was created for the gov't after all **\ {-olark}** Yep **\** if it will do good for cash/monero i guess those use cases will follow by time **\** Everyone seems to be ecstatic about libkovri but I must stress that this is a sensitive network so, the lib should be used with that in mind. **\** Tor doesn't have this issue. All that work is upon the relays. **\ {-olark}** True **\** Simply shutting down the router when it's most convenient has a negative impact on the network and anonymity. The API needs to take this into consideration as will any applications. **\** I can get into details, not meeting worthy. endogenic I don't think I answered your question well enough, I hope I can do better after the meeting. **\** Any questions about "brief review"? **\ {-olark}** Hang around in #kovri endogenic **\ {-olark}** Basically we are close to nightlies right? **\** ^ #kovri-dev is more informative **\ [i2p-relay] {Slack} [endogenic]** i’m here **\ {-olark}** :) **\** Yes, nightlies are technically available https://build.getmonero.org/waterfall **\** *but* **\** pigeons and I are working out packaging details. **\ {-olark}** ok **\** Right now they *all* run a hacked makeself installer. So, download -> chmod +x -> run the installer. **\** Windows requires msys2, this is silly so I think we can do a windows installer method (I posted details in the meta repo) **\ {-olark}** nice **\ [EinMByte]** Hi, sorry for being late **\ [needmultisig90]** oh its being relayed **\ [needmultisig90]** neat **\** needmultisig90 wants to head up the packaging front. needmultisig90: if you aren't watching the meta repo, I highly recommend that. **\ [needmultisig90]** link pls **\** https://github.com/monero-project/meta **\** If you review the issues, you'll see where are on packaging. **\** where we are **\ [needmultisig90]** Added, will do **\** I don't want to shortchange the work that's been done since the last meeting, any more Q&A before moving onto the next point? **\* anonimal** thinks too **\** Oh, yes, another new contributor alvinjoelsantos (I don't know if he's around) **\ [i2p-relay] {Slack} [needmultisig90]** ajs is cool **\ [i2p-relay] {Slack} [needmultisig90]** @ajs **\ [i2p-relay] {Slack} [needmultisig90]** he appears to be online **\** Oh, *that's* ajs, excellent. **\ {-olark}** Good to have new blood :) **\** ajs wanted to work on the website too, IIRC? **\ [i2p-relay] {Slack} [needmultisig90]** he's working with me on /r/moneromarket **\ [i2p-relay] {Slack} [needmultisig90]** I believe so **\ [i2p-relay] {Slack} [needmultisig90]** he has a background in law **\** "I am the law!" **\ [i2p-relay] {Slack} [needmultisig90]** and was working with OpenBazaar on drafting up arbitration agreements IIRC **\ [jollymort]** also on the monero stealth addresses script : ) **\ [i2p-relay] {Slack} [needmultisig90]** he can correct me **\** Have him take a look at /r/Kovri **\** does the website exist? i'm happy to help add content and such **\** bigreddmachine: we all need to tackle fluffypony because he's been coveting the website idea since we started **\** "MY PRECIOUS!" **\ [fluffypony]** bigreddmachine: yes **\ [fluffypony]** I moved laptops and so now half my stuff lives on my old one **\ [fluffypony]** I'll try consolidate and push it up this week **\** okay, just wanted to make sure i hadn't missed something. i'll watch the repo - going under getmonero.org or as a separate repo/site? **\** Last call for point 2. "brief review" **\** bigreddmachine: while you're here, we did make some progress on Salti. Any news from upstream on their API? **\ [fluffypony]** bigreddmachine: same design, new content, linked from the getmonero menu bar **\ [EinMByte]** Progress on salti? **\** EinMByte: yes, have you read some of the conversation in the open salti issue? **\** anonimal: i've been tracking the open tickets but everything got held during holidays. nothing there yet, but i might make a proof of concept for chromium if there'd be interest **\ [EinMByte]** "some of" yes, that sounds about right **\** bigreddmachine: sounds great **\** EinMByte: most of the collaboration was in IRC, not in issue. **\** it would be easy enough to port to firefox + tbb once they finish webrequests.proxy **\** bigreddmachine: will you open FFS for this? I think it's worth it. **\** for the chromium part? or ff/tbb? **\* anonimal** shrugs **\** i don't feel comfortable proposing something that at the moment isn't possible and relies on mozilla dev community before it can get started... **\** Ok **\** Chromium PoC sounds good none-the-less. **\** but i will FFS it once i think it's doable **\ [i2p-relay] {-ArticMine}** I would be careful with Chrome / Chromium since unlike Firefox there is no no option to disable DRM **\ [i2p-relay] {-ArticMine}** The DRM could be an attack vector **\ [EinMByte]** Anything that relies on mozilla sounds bad to me **\ [i2p-relay] {-ArticMine}** Firefox and clones are fine **\** ArticMine - DRM isn't included in chromium afaik. chromium is only open source code. **\** ... at least that's always been my understanding. **\ [EinMByte]** Firefox is fine, of course, and preferably we should use Firefox (or at least that was the initial idea) **\** anyway, we can discuss details after the meeting if there's interest. don't want to hold up anonimal **\ [EinMByte]** but relying on mozilla to move... probably not going to happen **\ [i2p-relay] {-ArticMine}** https://bugs.chromium.org/p/chromium/issues/detail?id=686430 **\** no chromium is even binary blobs download at compiletime **\ [i2p-relay] {-ArticMine}** The DRM in Chrome is currently an issue in Chromium **\** bigreddmachine: this is technically "3. Code + ticket discussion / Q & A" so we can chrome-it-up if needed. **\** Any other comments on Salti? **\** okay - maybe a chromium POC would need to stay just that, a POC, and never production. **\** Something to play with at least, I'm up for that. **\** "Any other comments on Salti?" --> just that i'll keep trying webRequests.proxy **\** Ok, thank you. That sounds ideal AFAICT. **\** Onto other code + ticket discussion: **\** Since I have no questions for myself, any Q&A? **\** Open PR from guzzi, ETA for completion? **\ [moroccanmalinois]** hi guys, guzzi are you interested in #399 ? i may give it a shot if you are not **\** Oooo #399, my favourite. **\ {-guzzi}** \* anonimal, this week on PR **\ {-guzzi}** \* checks 399 **\** moroccanmalinois: ironically, I highly encouraged guzzi to get started on that after we merged his PR. **\ [olark]** I'll leave what I have to say for after. **\ [olark]** Unless there are no questions people have about kovri **\** moroccanmalinois: but now that he will be funded, I would ask him to contribute partly to that and help me with many other areas instead **\ [moroccanmalinois]** @anonimal "easiest" one i find **\ {-guzzi}** sounds like a plan. **\** I mean, I can't speak for either of you; please do it! **\** Ok, so moroccanmalinois is on #399 now? **\ [moroccanmalinois]** my pleasure if guzzi is fine with it **\ [EinMByte]** Do we still have important SSU issues open? **\ [EinMByte]** Might take a look in the next week **\ {-guzzi}** but converting .jar to c is a great way to learn **\ {-guzzi}** we an decide away from the meeting. **\** #399 is actually great for various reasons, one of which would introduce a new dev to the purpose of libkovri-client and libkovri-core **\ [moroccanmalinois]** cool **\** EinMByte: yes, the same ones I believe since you left though I may have resolved one or two but not closed (I don't know) **\** guzzi: we wouldn't be converting .jar to c **\** I'll give details after the meeting **\** olark did you mean monero question for after the meeting or kovri question? **\ [EinMByte]** Alright. Might do some additional refactoring, since I never completely finished that **\ {-guzzi}** oh i see just skimmed **\ {-olark}** Not so much a question but a new development that pertains to both kovri and monero :) **\ {-olark}** Something I have been thinking about while I was looking at Monero's ring signatures. **\** EinMByte: that sounds great **\* anonimal** will look at issue tracker after meeting **\** Ok, anymore on 3. Code + ticket discussion / Q & A ? **\** Lots of TODO's. I'm adding them like spice to bland soup. **\ {-olark}** I'll mention it in 4. **\** Once I get these two branches merged, maybe someone can pick some of them up. We'll see. **\ [i2p-relay] {-ArticMine}** I will bring up an item in 4 **\** 30 seconds until 4. **\ {-guzzi}** i like todos **\** 4. Any additional meeting items **\** Floodgates opened! **\** Fashion, food, travel: anything goes! **\ [i2p-relay] {-ArticMine}** Yes https://www.myhackerhouse.com/windows_drm_vs_torbrowser/ **\ [i2p-relay] {-ArticMine}** DRM used to attack tor in Windows **\** lol **\ [i2p-relay] {-ArticMine}** Cost to get Windows to trust this attack 10,000 USD **\** Thanks ArticMine, looks like a great read. **\** bigreddmachine: ^ **\ [i2p-relay] {-ArticMine}** Should also work against i2p **\* anonimal** will read more after meeting **\** fluffypony: are you gpg verifying the kovri subscription that's hosted on github? **\** okay, so i'll go ahead and say that i won't officially ever support a chrome version of Salti then. **\ {-olark}** I'll let ArticMine go first **\* anonimal** wanted to ask that in monero's meeting on the topic of github security **\** "subscription" ? **\ [EinMByte]** By the way, if anyone needs access to the salti repo, please tell me **\** moneromooo: https://github.com/monero-project/kovri/blob/master/pkg/client/address_book/hosts.txt **\ [i2p-relay] {-ArticMine}** My take is that any browser / OS that supports DRM is vulnerable to an attack against anonymity / IP obfuscation **\ [EinMByte]** As with many features like DRM, it's best that they're just enabled **\** Thanks. **\ [EinMByte]** \*disabled LOL **\** lol EinMByte **\** moneromooo: the only reason I'm signing it is because fp is pulling directly from github **\ [i2p-relay] {-ArticMine}** So i2p on such a platform may create a very dangerous sense of false security **\** ArticMine: much like anything Windows **\* anonimal** now windows fan **\** \*not **\ [i2p-relay] {-ArticMine}** Yes **\** olark: 10 minutes left **\** Tick tock tick tock! **\** fluffypony: in addition to my ping above, is there any kovri-related news related to your conference circuit? **\ {-olark}** Salti is a good solution for now **\ {-olark}** In the future we could have our own dedicated browser **\ {-olark}** Not sure when that is viable though **\ {-olark}** ok **\ {-olark}** sorry got really bad tunnel lag **\ {-olark}** I have been thinking about how LN or something similar would work with monero **\ [fluffypony]** anonimal: just generally good chats **\ [fluffypony]** Nothing mind blowing **\ {-olark}** Once kovri gets implemented into nodes and wallets this opens the doors to some really great developments **\ [fluffypony]** Some good talk on Tor failure modes **\ {-olark}** Since we would have access to i2p for routing **\ [fluffypony]** A few people at 33c3 said that i2p was a prescient choice **\** kovri - the prescient choice for online anonymity **\ {-olark}** It would need to be a plugin for kovri **\* anonimal** wants Kovri's I3P technology. Trademarked, stamped, hah! **\ [fluffypony]** Hah **\** I3P, your cover of choice. **\ {-olark}** Could have a client tunnel for LN functionality in wallets **\ {-olark}** Use kademlia DHT so the other "lightning" nodes know of each other **\ {-olark}** Would be able to route around centralized troublesome nodes **\ [fluffypony]** Can I shut meeting-bot down, anonimal **\ {-olark}** Fixes a lot of problems the current LN development is trying to fix **\** fluffypony: 3 minutes left? **\ [fluffypony]** Kk **\ {-olark}** Don't need to build routing from scratch **\ {-olark}** Anyway it is still way to early to really till this could be possible **\** olark: sounds interesting. I'd need more info to have a comment. **\** moneromooo - I'll work on the isolated testnet in a bit. I apparently need to rebuild all of my monerod's w/o libunwind, or it crashes trying to init a new blockchain. So I'll have it tested a bit later today. **\ {-olark}** But there is good potential **\* anonimal** swats Snipa **\** Cool, thanks Snipa **\** Ok, one minute left. 5. Confirm next meeting date/time **\** Same time, two weeks from now? **\** february 19? i can do that **\ {-olark}** Sounds good **\** Ok, I'll post on meta repo. **\** Thanks everyone!
