we're (re-)building a platform for virtual art fairs in the wake of coronavirus — most fairs and galleries are cancelling or postponing events that will work super well online. We're building a novel experience from the ground up, not relying on VR or skeuomorphic interactions
Since fraud detection is done on-device, is there any clever encryption or security features that stop me from issuing a direct API request to the service with my (or someone else's) credit card info? If not, I'm worried that a technical fraudster could script their way around the ML model (and therefore not need the physical card), especially since cc lists are already nicely formatted. This would hurt pretty badly if the service assumes that DyScan is infallible and then doesn't have mechanisms for detecting fraud post-signup.
Great question! The company that owns the app is ultimately responsible for the encryption there, but there are a few ways we can help out with that as well (sorry, I know this is a terrible answer - but it's best practice not to reveal too much about how the encryption works)
I second the references to "Mastering Bitcoin", and also add my blog post "Getting up to Speed on Ethereum" [1] that takes you from "I kinda understand bitcoin" to "I understand ethereum at a deep level and know about the big projects being built on top of it" over a few days.
It shines when you search for something that you want the best version of, without caring about the details; i.e., let the masses determine the quality for you. It weights results based on ratings, review volume, and some other stuff, segmenting the results by price range.
Helps me answer the question "I want the best phone mount for my bike, but I don't want to spend more than $20" without fiddling with Amazon's search parameters and then scanning the page.
I have, but the API differs in availability/completeness across regions and writing the code to handle each region probably isn't worth the time. The Product Advertising API is also _terrible_ and not fun to work with, so I'm minimizing the amount of time I spend working with it and reading their docs.
1000 uniques/month on average, not including when I post the site on hacker news. The clickthrough/conversion rate is pretty solid. 35% of users buy something after clicking through to Amazon, which makes sense cause it's a pretty strong signal of intent.
Ah, if only people backed Dokku monetarily[1]. I'd probably get my ass in gear and release the multi-server functionality I prototyped over the summer.
Nice to see that others are finding Flynn useful though, there is plenty of space for PaaS offerings, and I truly hope they are financially successful.
[1] My experience in this area is that it's hard to get peple to pay for something that is free, which dis-incentivizes work/releases. I'm not surprised that many use the free version of Flynn, or that there were a ton of Heroku users that left once they stopped getting free resources 24/7. Dokku does take donations - https://opencollective.com/dokku - but to be quite honest, it's almost certainly nowhere near even 1% the amount of money we've saved our users.
As an aside, you might consider a tool similar to the docker tooling that can help manage multiple dokku hosts on different cloud platforms... People seem to be more inclined to pay for things like that.
I just want to say, that while I haven't financially contributed, that I do appreciate the work that has gone into dokku, and it's a great platform for self-hosting smaller projects on a single vm.
People seem more willing to pay for features upfront, so a Kickstarter
might be a better way to fund the development of the multi-server functionality. I am yet
to use Dokku for anything but I'd contribute to that Kickstarter. (Though I
have to say that when I evaluated Dokku I loved how simple it was compared
to the alternatives, so if Dokku
gets multi-server support I hope it isn't at the price of its simplicity.)
There's also Comedy Hack Day [1], my personal favorite hackathon(s) of all time. I've been to 4 so far and have flown across the country just to participate over and over again.
