I agree, no horizontally-scalable system is infinitely scalable in any dimension. You will hit some limit - for example, you might be able to support arbitrary scale in some dimens…

I've run a disclosure program for ~7 years, which is an open paid program. However, over that time we've developed relationships with the most active and successful contributors, t…

I wrote about this this morning [1]: > We're keeping our vulnerability disclosure program open - because even though they are rare, the genuine critical reports we receive, in amon…

Disclaimer: I work for Ably. I agree in principle, so the libraries that handle websockets and also fallback transports using comet (eg SocketIO) are still widely used for that rea…

This ^ is my favourite writeup on the question of how you implement SOC2. I wish I had read that before we started - after going through the Type 1 and Type 2 process, we've ended …

We've been experimenting with Liftbridge at a range of scales and workloads, and clusters that are distributed across a single region perform very well. However, it's not really su…

I can't speak for NATS streaming or Akka but it does look like liftbridge can fit that niche very well, depending on what features and semantics you need. Your services that publis…
