What about forum software like Discourse or Flarum https://flarum.org? However Discourse is a bit expensive.
In addition, I'm creating a Pay-what-one-wants alternative to FB gropus and Meetup and email lists ... It's sort of a cross between StackOverflow, Slack, HackerNews: https://www.talkyard.io (open source).
What do you like the most about Groups.io? if I may ask
I have a SPA and have 'converted' it into a PWA. My motivation for that largely has been to better control the way assets are cached on the client, I can now control better with the service worker, but there is one really nice benefit:
With the PWA, android devices (hopefully iPhone soon too) can 'install' the PWA to the device without going through Google Play Store (in fact, you can have the PWA install the android app available on Play Store instead, if you prefer). This makes the web-page appear to the user as an app, with a nice icon, and snappy performance relative to opening a link in chrome (even though it is a chrome instance running the 'installed PWA')
Agreed. I had run a small BTC arb program for a bit a number of years back. The exchanges were shoddy, there was a persistent bias in the arbitrage such that you ended up accumulating huge positions of BTC on one side, and lots of short cash on the other. Couple that with the difficulties of withdrawing cash from the system, fees, etc., it was not worth the risk. But this is not new.
What's pretty cool about this -- though it appears this site is not focused on it -- is the opportunity for full triangle arbitrages among the various crypto's, such that you may do, e.g., a BTC->ETH->LTC->BTC trade and wind up with more BTC than you started with.
Another point to consider; the big players have moved into this space, if you want to get into it you will need to be sure you're not at an informational disadvantage.
I created a script years ago that looked for arbitrage opportunities on BTC-E, up to 4 trades deep, and it used the order books properly. I left it running, and was surprised that it actually found some arbitrage opportunities, around once every 3-4 minutes. Unfortunately the profits were always lower than 3-4 transaction fees of 0.2% each, so my dreams of getting rich quick got crushed.
I'm was actually surprised BTC-E didn't do something like that themselves, since the they don't have to pay any transaction fees, and they also had zero lag. It's like free money.
I agree with the statement in the article that the current Web-of-Trust model is broken. I think that is one thing that the folks at keybase (keybase.io) understand, and I like their model. I like it enough, in fact, to actually use it, something that I cannot say about GPG despite having tried it on numerous occasions over the years.
GPG is proposing going to a TOFU model (trust on first use, much like ssh works). I'll be curious to watch if that takes off, it seems like a step in the right direction.
I think 'trust' as a concept is difficult to codify into a protocol. What alternatives are there that would be better than what keybase.io does, or what GPG is proposing?
Last time I tried to use keybase it required me to paste my private key into a browser before using any of the advanced features like chat. This seems unnecessary and doesn't make any sense from a security perspective. Has the situation changed? I won't use their service until this is fixed.
If I recall correctly, you can choose to let keybase store your password-protected private key for the purposes of decrypting messages through the website, but that's not required, and the advanced features (e.g. chat) don't work without a local install. Everything that can be delegated to the app (GUI or command line) generally is. The keybase team seems to take this quite seriously, and they've had documentation on how to use the platform without giving their servers any information since at least when I joined in early 2014.
Give it a shot, it's quite painless as far as crypto products go. You can always choose not to use it if you decide it's storing too much information. Happy to provide an invite if you (or anyone else) needs one.
I'm curious about your statement that you're using keybase, but not GPG. If you're only interacting with others that are using keybase, I assume that's possible, but if you're interacting with others, you're going to have to use GPG, right? Keybase can handle public keys, but your private key is yours. Or am I missing something?
Keybase has increasingly moved to its own crypto model that isn't GPG backed. Even in cases where "traditional" PKI RSA and ECC curves are used, it doesn't use the GPG tools anymore and instead other open source implementations.
JFYI, I find it simpler to use this method, (same method of halving and doubling) used often for Roman numerals multiplication, but in the version that uses two colums only, crossing out the lines not needed (more similar to the "sieve" approach BTW):
Thanks for fixing the link - I was going to remove this comment for the sake of being tidy (sys admin thinking) but it appears I can't delete it, only edit it.
