Why didn't you go down the route of Paxos Commit for your ACP versus the Yabandeh-style ACP? I realize that they have very different semantics, but Paxos Commit seems to have (nearly) all the same properties, and benefits without a sin

They have Multi-Raft running between all of the replicas of a specific key range to ensure that there is an atomic commit across all DCs.

Personally, I love DevOps. I've played on both sides of the fence. More ops than dev, I'll admit. The way I view DevOps is that you have end-to-end guarantees about software delivery. A lot of this draws from personal experience,

Two things: 1) The developer would just say - no, instead I'm not going to use IPSec, and I'm going to bootstrap this myself with TLS. I'm going to push complexity UP the stack, not requiring esoteric network hardware to do t

I'm really surprised Mesos and YARN weren't talked about in the article as they've actually been used to build multi-cloud environments.

What was Scalien, and its purpose?

Paxos is poorly explained in the multi-decree method, because the explanation isn't particularly opinionated about how SMR and logging is done. Raft only has a multi-decree variant, and it has opinions on how to do leader election, etc

So, byzantine failure is neat, but I've never actually seen a system used that implements true byzantine Paxos, I'm really not sure what kind of production system would implement it.

You don't _NEED_ the GPS tricks and all, and realistically you can replace some of the HLC code in Cockroach with a time network time server implementation that speaks to GPS / Atomic clocks, if you want.

So, is the primary model here to be an IDS / IPS vendor? It seems like that? http://traversalnetworks.com/product What kinda tech are you using?

I used to work in networking. One of the things that always amazed me is people's willingness, or excitement to be pinned to one proprietary networking system. On the proposal of a network that utilized primarily open standards, they w

Where is the documentation for BPF? For example, let's say I want to mangle packets and change the encapsulation on them. How would I go about doing this? It seems like it's a full-on VM. Is there any description of the language -

I'd like to also add to this that SCTP doesn't ship on Mac OS X either by default. Although, in recent years there have been development on an SCTP over UDP standard, allowing for user-mode SCTP. Yet, I still haven't seen a m

This is super interesting for embedding into servers as an HSM-like device. A lot of servers have SDIO ports internally. Any idea what the cost is going to be?

If I remember correctly, Datomic is more of a data modeling layer / transaction manager, and less of a database.

I'm very curious how far OrientDB has made it. I remember using them ~1.5 years ago, and it was plagued with bugs, and data loss issues. Maybe they'll be able to take some of the knowledge from the MongoDB folks, and use it to bol

I feel like this is an implementation of my idea here: https://medium.com/@sargun/interviews-as-a-service-dfa6d4a03... -- Or at least a competing alternative to traditional interviews.

RE: The last one QUIC is a solution for that - It's Google's answer to TCP, and dealing with multiplexed connections. I recommend taking a look.
