CNCF video¹ of the talk² we gave together with @markpoko "Where's your money going" regarding #kubernetes #costs focused on workload bin-packing, +slides and some promql fun at³ ¹ youtube.com/watch?v=8eiLXt… ² kccncna2023.sched.com/event/1R2vE ³ github.com/jjo/talks/tree…

@marcosnils @popovicu94 x-platform and x-arch (of course being Golang + FUSE), I use a common "share" between x64, ARM64, and old raspi ARM32

@marcosnils @popovicu94 +1k syncthing! Put github.com/rfjakob/gocryp… on top, and you have a (close-to) distributed encrypted filesystem mount -- #gocrypts shines when others (like encfs) fail when their underlying backing files change while mounted

My flow: Mac as daily driver, Linux box as local server in the corner. Files move between them constantly. I tried the sync apps. Even paid for one. They all want to be a product: indexing, watching folders, dashboards, accounts, whatever. What I actually landed on is mc. Midnight commander with two panes. One pane local on the Mac, the other pane on the Linux box over the SSH link I'm already using. Copy, move, edit, pipe, done. It doesn't need addons for the server. It rides on the SSH connection. If you can ssh into the box, you can drive both filesystems from one keyboard. Things I use it for: - Moving build artifacts between machines mid-iteration (the main one) - Pulling my website build output to the Mac, since the build itself runs on the Linux box with a pretty involved pipeline - Dropping a dataset onto the server before kicking off a long job - Pulling logs back to the Mac when I want them sitting next to whatever else I'm reading What's your move for shuffling files between a laptop and a home server?

Warp is now open-source.

hola @grafana #meetup friends! este Miércoles 29 de Abril a las 6pm rebooteamos nuestros meetups @#mendoza 🎉 porfa inscríbanse para asegurarse el hardware (☕️ + 🥐 + 🥯 = 😋) meetup.com/grafana-friend… l@s esperamos para explorar tópicos de #observability 📊, en buena compañía 🤓

@nerdearla Thanks @nerdearla for such great event! My talk (in Spanish) is now available at youtube.com/watch?v=VJCrOw… slides at bit.ly/jjo-GameOver-K… and #kubernetes scheduler and cluster-autoscaler "live" simulation showing its binpacking challenge at bit.ly/jjo-KubeTetriC… /cc @learnk8s

👉 “Game Over en la factura: jugando al Tetris de costos en Kubernetes” Juan Jose Ciarlante (@xjjo) te enseña cómo dominar el Tetris de costos en Kubernetes sin sacrificar rendimiento. ¡Métricas accionables y trampas a evitar! Imperdible. 📌 BiblioGAM y virtual por nerdear.live #Nerdearla 🇨🇱

@marcosnils IMO there's place for both approaches --bluesky brainstormy vs product-oriented-- 100% agree that *requiring* the latter kills doing it for-the-hack-value, one of the most enjoyable experiences

Algo que no me gusta de las hackathones actuales es que hay mucho foco en hacer un producto que logre capturar usuarios. Antes no era así. La idea de la hackathon estaba más enfocada en pensar fuera de la caja y resolver una problemática con algún factor cool.

@nerdearla 2/ 2/ #kubernetes #clusterautoscaler #simulation, attached "dead" mp4, but "live" HTML5 simulator at bit.ly/jjo-KubeTetriC… 🤓 my @grafana team mates would recognize the pain «behind the scenes»

heya @warpdotdev when are you going to fix the serious warp terminal memory issues in Linux? it's truly unusable ... just starting it w/o any work ahead ate 22GB of RSS (!) and yes, I'm a (now frustrated) paying suscriber

Having a very bad experience with @AncestryCA , I just need to reprint a return label for the sample, chatting to a bot that won't allow me to connect to an agent, one of the worst customer experiences I had, for a kit that's pretty expensive already

Our #Kubecon session with @salaboy about Taming application environments with @dagger_io and @daprdev is already available to watch youtu.be/PSenmCMU5mQ

@BenjDicken tnx for this! added WASM output for Go, re-ran the C (native) and Go (native, WASM) in my rather old laptop, results at #file-summary-md" target="_blank" rel="nofollow noopener">gist.github.com/jjo/4d9a822b2f… TL;DR: both Go targets essentially run @ same wall-time, but the WASM one topped 55MB RSS while native 1.8MB only /cc @wasmerio @golang

1 billion loop iterations. 4 languages. I wrote the same code in js, python, go, and c. Timed executions on a digital ocean dedicated cpu vm, and here are the visualized results. Not all programming languages are created equal!

Today on @KubeCon_ we released @PrometheusIO 3.0 It was a long and amazing journey thanks to all 68 contributors since 2.55 and near 1000 since 2.0! 💪 New UI, query explore, UTF-8, @opentelemetry comp., Remote Write 2.0, better perf and more! ❤️ prometheus.io/blog/2024/11/1…

@salaboy @PeladoNerd @KubeCon_ Heya! Maybe we can meet tomorrow for lunch? 😉 (not doing booth this time)

I’ve finally had the pleasure to meet @PeladoNerd in person! It is kinda awesome to meet someone from Mendoza 🇦🇷 in Salt Lake City 🇺🇸 @KubeCon_ 🤩🤩 we miss @xjjo here !

random thought moment of the day ... From 0 (`𝚏𝚊𝚕𝚜𝚎`) to 1 (`𝚝𝚛𝚞𝚎`) there are infinite rational and irrational points with all the decimals you'd need, and the 𝘧𝘢𝘤𝘵𝘶𝘢𝘭 𝘵𝘳𝘶𝘵𝘩 lies[punt intended] somewhere in-between.

My 1st @PrometheusIO contribution at github.com/prometheus/pro… just got merged 🎉, thanks @juliusvolz ! 🙏appreciate feedback on these new `limitk()` and `limit_ratio()` additions (note you need to enable them via experimental flag)

They've gone full mask-off: 𝐝𝐨 𝐧𝐨𝐭 𝐞𝐯𝐞𝐫 trust @OpenAI or its products (ChatGPT etc). There is only one reason for appointing an @NSAGov Director to your board. This is a willful, calculated betrayal of the rights of every person on Earth. You have been warned.
