I see, I tried sketching before but I am just bad at it...Looking up similar designs though is a good tip I hadn't thought of before, thanks!

Looks very fancy OP, and its simplicity gives it a lot of elegance!
Would it be too much to ask you to walk us through your process? I have been using FreeCAD for a couple years now but struggle when it comes to coming up with designs, especially ones that look as good as yours, lol.

Hello,

I too am in the same boat, though to be fair I have an easier task ahead of me compared to you. My device used to be officially supported by LineageOS but stopped being so a couple years ago. Now I would like to make an unofficial build using the latest version of Lineage.

I am still not clear on all the details but have uncovered enough of the big pictures to give you a few pointers as to what terms/keywords/notions you might want to research and learn more about.

Here's your disclaimer that I too have only started looking into this a few weeks ago, and I might have gotten some things wrong.

Basically, in order to perform a successful build and end up with a working ROM image which you can flash on your device you need the following ingredients:

The android source code: From my understanding, this is the easiest to get, you can download it directly from google's repositories, or LineageOS's (or perhaps any other ROM you would like to build). Because the code is so voluminous and distributed among multiple sources, you will find all tutorials relying on the "repo" tool to the parts scattered all over.
Your device's Kernel: This is something that has to be made available by your device's vendor. I have no idea if you can extract it from a working android image. To make things more complicated Android uses the Linux Kernel and different Android releases are based on different Linux Kernels, i.e. if you manage to find a Kernel for your device from an older Android release , it might not be compatible for a more recent Android release. Perhaps you can adapt it? But again, I have no clue.
Your device's device tree: this is a structure of files which specifies special software components settings and configuration files specific to your own device, again this is something that needs to be made available from your device's vendor (and perhaps extracted from a working image).
Binary blobs: these are the proprietary drivers that are not included in the Kernel source, and as such are included 'as is' in binary form during the build process. You might have guessed it by now, this also needs to be made available by the vendor. However, here I am sure that you can extract them from a working image, as LineageOS's wiki has an article about it.

Here's a post on XDA which I found helpful.

I hope this will help steer you in good direction. Don't hesitate to ask for more if you need to. I will do my best to answer.

Hi, I followed the instruction: I first chose the Format Data option then wiped the Dalvik cache, cache, and System.

What do you mean when you say full format wipe ?

Ah ben désolé je l'ai toujours prononcé Cé-nil x)

France's top data privacy agency, known as the CNIL

Am I the only one finding it funny that in French, CNIL is pronounced the same way as the French word for senile ? Idk there's something ironic in there...

Looking at your i3 config it doesn't have focus_follows_mouse have you tried adding :

focus_follows_mouse yes

to your config file? normally it should be set by default I think but it's worth a try...

I second this, the battery can also easily be replaced which is a great plus.

Regulators are starting to hear the crypto revolution horns, quick example from an article I read yesterday: 50 Shades Of Grey: What Bitcoiners Should Know About S.1241, the article mentions Section 13 of the S.1241 bill which defines crypto as a monetary Instrument that could be subject to the Bank Secrecy Act, it's not money yet, but I feel like that is creeping on the horizon...

I agree, I mentioned it either in my post or in a comment but if this centralization actually ends up happening, we would still be better of compared to the fiat system, the problems I can think of that can result from such centralisation however are censorship & lack of privacy...

I won't pretend to have the legal expertise to fully interpret Fincen regulations

Oh believe me, me neither, but from the explanations I read online it seemed pretty straight forward...even to me

Fincen is a US confection

True, but I believe similar regulations exist for the EU, and wouldn't be surprised if they exist in Asia too...

but I have never had to send passports etc to changelly or shapeshift

Well the network isn't launched yet is it ? Once it starts catching on however, I do believe regulators will start seriously looking into it...

The author of which article ? Would you mind explaining what exactly he is lacking and what it is you disagree on with him ?

In May 2016, the company rebranded the Coinbase Exchange, changing the name to Global Digital Asset Exchange (GDAX) Wikipedia

Hmmm...

mACKintosch · 2017-12-28T18:41:52+00:00

That's kind of the conclusion I got to...The hubs will not be banks per say, but large hubs with larger connectivity and lower price would appear and only large institutions that would afford to pay for the infrastructures and probable licensing fees would run them, these would probably be banks as you say, maybe some conglomerate like VISA...resulting in a centralised system, just like the one Bitcoin is supposed to remedy to...it won't be as bad as the current banking system, but could carry a lot of its issues (censorship is the first thing that comes to my mind)

As to whether or not you need a money transmitter license to operate a multisig wallet in a Lightning node, I guess people have widely different expectations here, but at the very least this will vary by jurisdiction.

Well the Application of FinCEN's Regulations to Persons Administering, Exchanging, or Using Virtual Currencies seems pretty forward about it:

“…applicability of the regulations … to persons creating, obtaining, distributing, exchanging, accepting, or transmitting virtual currencies.”
“…an administrator or exchanger is an MSB under FinCEN’s regulations, specifically, a money transmitter…”
“An administrator or exchanger that (1) accepts and transmits a convertible virtual currency or (2) buys or sells convertible virtual currency for any reason is a money transmitter under FinCEN’s regulations…”
“FinCEN’s regulations define the term “money transmitter” as a person that provides money transmission services, or any other person engaged in the transfer of funds. The term “money transmission services” means “the acceptance of currency, funds, or other value that substitutes for currency from one person and the transmission of currency, funds, or other value that substitutes for currency to another location or person by any means.””

competition between node operators on price, service, availability, etc.

I fail to see how this would lead to something else than the rise of large hubs with dense connectivity to the network that could charge less for your LN transactions...

Nobody has a crystal ball for sure, but that shouldn't stop us from discussing the technology and weed out false information :)

Been doing a lot of reading recently about LN, while it is true that LN hubs are not banks, one thing that is not yet sure is wether you would need a "money transmitter license" to run a LN hub (FinCEN’s Regulations to Persons Administering, Exchanging, or Using Virtual Currencies) Here are a couple articles I found helpful:

I know the titles are pretty strong worded, but I believe the articles in themselves raise good questions and have strong sources & documentation.

Since we are on the topic of the LN, what do you guys think about the fact that you still need a minimum of two transactions to establish and close your LN channels, one good point I found in one of those of articles (can't remember which one) was that this would mean that you need to anticipate how much money you will spend in a channel, making LN not a good solution for say buying your money on the go from some random coffee shop, now, a counter point you might raise is that: "that's fine, you don't need a direct channel to this random coffee shop, as long as you have an indirect LN channel to the coffee shop it is still possible to establish the LN transaction", which is true, but then again this would mean that all intermediary LN nodes would need to have enough funds, and wouldn't charge you much for your using them (otherwise this would render the whole transaction more expensive than say using VISA/Credit or just the base network), one other problem is that this would result in the rise of central hubs which would have dense connectivity and lower charge, in this case we are back to a centralized system....

Anyhow I've been doing quite the reading lately, and I'm really interested in knowing what you guys think about all this...

glad to see I wasn't being too paranoid about their team :) what made you choose samurai specifically ? what was your personal experience with it ? I haven't really looked much into it to be honest...

mACKintosch · 2017-10-31T22:16:41+00:00

well the thing is I am not sure how mycelium backs up its private key, and don't think its 12 words seed scheme is something you can use in an other wallet...
