A sales person from the company contacted me a while ago to offer services, Jessica De La Garza <Jessica.DeLaGarza@rackspace.com> and talked about their services. They have always been about their "Fanatical Support"
Small coins can use merge mining if they really want to, most don't because they have some far-fetched idea on how PoW should work (like "ASIC resistance" and other tarpits)
The method they used of encoding the transactions into the output value of the transaction could be done a LOT cheaper if they just mine transaction hashes with 16-bits of prefixed data. It's not that hard to create a transaction over and over until you get the first 16-bits of it's hash exactly as you want (in essence this is basically what Bitcoin mining is, just simply on blocks instead of txs)
Also they could just do it with 4 transactions at 8-bits each too.
To prevent MITM/downgrade attacks (such as by someone at the same coffee shop) you should always use an HTTPS link. Malicious parties can inject ads, trackers or botnet mining scripts otherwise. Here is a secure mirror:
I think Apple would only be happy if those environments exposed all future APIs on the day they are released, which is a very difficult promise to make.
I'll take a provider that is transparent over one that makes claims they cannot backup. cock.li is more transparent in that regard despite being a complete meme.
Uploading can still happen even without open ports. The open port part is that someone has to initiate the connection after the connection is established anyone can send anything in any direction.
All ports should be open between servers. (Edit: Ports should be open if you want. I'm not saying you should run without a firewall, but on a server the firewall is under your control, not your ISP's.)
A few of the DiSo protocols were based on XMPP instead of HTTP.
