One of the teams @MongoDB that develops and supports our cool performance testing infrastructure is hiring for multiple roles in Sydney! This is the performance infrastructure that I've talked and written about. grnh.se/12fcef271us

Give yourself an early Easter present and join us at ICPE! It’s free of charge and we have great speakers (keynote and otherwise :) )!
Very excited to see the #ICPE2022 keynote from @Google's John Wilkes on "Building Warehouse-Scale Computers," taking place at the 4/9-4/13 virtual conference. Learn more about this year's keynotes at: ow.ly/U0Nc50IrGb0 Don't forget to register - it's free!

Ever wondered how the performance of #Serverless applications changes WITHOUT code changes? Over 10 months, we observed significant changes on #AWS in our @JSSoftware paper "A case study on the stability of performance tests for serverless applications" bit.ly/38kG5ZH

This paper is the result of a collaboration within the @spec_perf research group 'Devops Performance' together with Lizhi Liao, @DiegoEliasCosta @andrevanhoorn, @corpaul, @swy351, @skounev

I’ve been using #AnnotatedEquations in my recent papers. I think it really adds to the readability and understanding of the math. Here are some examples. It uses #tikz in #latex. Let me know if you like it. Happy for any feedback. [GitHub link: next tweet] #AcademicChatter +

Your regular friendly reminder… These datasets all have the same mean, median, and variance. Moral of the story: Always visualise your data!

Shoutout to the amazing collaborators that made this possible: Johannes Grohman, Long Bui, @cabad3, @HerbstNikolas, @skounev Overall, @2021Acm was full of interesting papers and lots of fun, will definitely attend next year again :)

Our paper "Sizeless: Predicting the Optimal Size of #Serverless Functions" has been accepted at @2021Acm. We predict the optimal memory size WITHOUT active performance tests and evaluate it on 4 realistic serverless applications. Check out the preprint: bit.ly/3C8s0Z8

To determine the current state of #Serverless applications, our new TSE paper analyzes 89 applications and data from @Azure, @datadoghq @newrelic @goserverless @fastly @OReillyMedia @thedashbird @CloudNativeFdn @thenewstack. Preprint: bit.ly/39x6TTx 🧵on findings ⬇️

Also, have to commend TSE for a crazy fast peer-review process of less than four months from submission to acceptance.
