That tool I wrote some years ago because you couldn’t be arsed to find a #batch #queueing and capacity management tool? It’s being rehabilitated to work with present-day versions of tools and libraries.
I hope you’re happy, #developers. Enjoy your hollow victory over many years of refusing to address #technicaldebt. I will be keeping the #receipts.

Lab 7.1 : QoS
https://zpr.io/CwFMy8i55guk
This lab will provide a demonstration of how to configure Quality of Service (QoS) on a MikroTik router, showcasing the different methods available for setting up traffic queuing.

@johnonolan Are you grouping by domain and sending to it's shared inbox instead of individually to each subscriber's inbox? That would be an early win.
Then also having a delivery queue that limits the number of outbound connections at a time would also lessen the need to scale up to so many servers for one post to 5K subscribers. Look also to bulk email implementations for inspiration, which have a normal queue, then any that are stuck get moved to a separate try-later queue with it's own separate sending threads, and some back-off-on-error algo.

"Members of the British public have chosen to trample on decades – nay, centuries – of tradition. That’s right – people have started queueing in pubs."

Things I'll probably never understand about #queueing while #traveling:
People that stand up at the earliest sign of boarding and wait in line at a closed #airport gate and don't just chill in the chairs until the line moves and is a bit shorter.
Surely you'll all get the seat you've been assigned? This isn't the USA after all...
(Families with kids I can somewhat understand)

A few hours ago we moved the last trickle of jobs over to latency-based queues. We're slotting into one of:
* within_30_seconds
* within_5_minutes
* within_1_hour
* within_24_hoursWe've hit a few snags - blowing those SLAs when slow jobs clog the works, starvation, unable to detect and auto-scale the lower latency queues fast enough, etc… Those problems were always there, but we didn't "see” them, and so didn't address/talk about them. Now we see them. And fix them.

Next was an interesting talk by Eva Tardos on learning in strategic #queueing systems. I don't think I've thought about queueing since undergrad, but it's always fascinating how small tweaks in approaches can yield massive gains in performance https://www.youtube.com/watch?v=l2bvbCyl2Tw (3/6)

So I am attempting to understand Queueing Theory that is more advanced than Little's Law and of course came across Defunctland's history of Disney's FastPass. I had a big guffaw when they showed an excerpt of a M/M/1 paper, scoffed at how you'd have to hire an engineering team "just to get to the bottom of this incredibly niche curiosity..." and then they do just that. So great.
