Zombies are costing us money, eating electricity, and belching carbon. Holly Cummins, Quarkus Senior Principal Software Engineer at RedHat, has some practical solutions to help you eliminate these zombie servers. Learn about utilization, elasticity, and sustainability, and discover techniques like LightSwitchOps, FinOps, and automation to help you save money and reduce carbon emissions: https://www.infoq.com/news/2023/03/stop-cloud-zombies-qcon/

@whereistanya I ended up posting more on twitter than here during #QConLondon, but only because of a useful UI feature that twitter has and my mastodon client doesn’t.

If I’ve searched for a hashtag on twitter and hit ‘compose’, then I’ll automatically get that hashtag in my reply. My mastodon client doesn’t do that, and I’d have to type it in manually each time (or forget…)

If I’m lucky one of my favourite mastodon clients will add it sooner or later - I like being able to have longer posts!

@adrianco talking about cloud provider sustainability and the need for a workload carbon footprint standard at #qconlondon. my recap for @infoq

Shout out to @mtnygard's "Release It!" for inspiration on building Netflix's resilient cloud native applications, by @adrianco at #QConLondon

I'm pretty jaded, y'all. But Microsoft’s keynote from #QConLondon is SO IMPORTANT.

So I wrote about it for The New Stack to think over, research, and amplify his suspicion that hateful history is repeating itself with #ChatGPT and #GenerativeAI. Get ready for some #AIbias.

I'm really enjoying tech conference chatter on Mastodon. It was one of my favourite things on Twitter, and it seems to have transferred really well. Maybe even better because you can follow the hashtag in your main feed.

I've enjoyed vicariously going to #QConLondon and #SRECon23 and I'm looking forward to a lot more.

Another tech conference with another VIP ladies’ bathroom experience at #QConLondon. Please, companies start tracking and sharing who of your staff gains access to the privilege and budget of attending events. #womenintech

What we talk about when we talk about networks by Keith Winstein

I’m sorry that this wasn’t recorded because I’d love to go through in slow motion!

Practical examples of changing parameters allow dramatic new compute models.

Must check his papers!

A good starting point would be his home page here, which clearly covers some of the things he touched on today (and more) cs.stanford.edu/~keithw/

Use #LightSwitchOps to kill zombie servers.
@holly_cummins #QConLondon

The one #sustainability slide you need, from @adrianco

things dev can do now
- optimise code
- choose faster languages and runtimes, like rust [or quarkus! 😁 ]
- efficient algorithms
- faster implementations
- reduce retries and work amplification
- reduce logging

things ops can do now
- higher utilisation
- automation
- relax over-specified requirements
- archive data
- deduplicate data
- choose time and location for workloads carefully

Adventures in performance by Thomas Dullien

Interesting points:

Our languages are designed for computers that are extinct. So are our databases.

Most orgs have 20-30% quick wins left on the table

This wide ranging talk considered historical, technical, organisational and mathematical considerations on the way to better performance.
#QConLondon

Sara Bergman explains it's ok to estimate when doing SCI (https://github.com/Green-Software-Foundation/sci) calculations. "SCI is a tool designed for *action*, not for reporting. So if you put a constant in your model, it's ok if it's wrong as long as you keep it constant in your math, and also in real life."

#QConLondon

"So what we need to do is - and by 'we' I mean all of us, not just me, although I am technically two people at the moment." 😆

Love to see Sara Bergman representing 💪 pregnant engineers at #QConLondon ❤️

"To make software green, we need to extract the maximum usefulness from every gram of #carbon it emits."

- Sara Bergman, #QConLondon #sustainability

"I don't suggest we do a drinking game, but I've probably said '#carbon' about 30 times already this talk. 😁 By that, I don't mean 'C' in the periodic table, I mean 'carbon-dioxide'equivalent'."

- Sara Bergman, #QConLondon

"That way we ended up with pair programming at Netflix without having to tell people to do pair programming; we just put them on call [and they made sure they had a buddy who also understood the service and could share the load"
