There are services like this where you can exchange your Airpods for ones with replaced batteries! Note that I've never done it and can't vouch for the quality. I just read about it on HN once.

I'm a new grad who's starting his first big boy job tomorrow.

Finding Projection Lab in that first Projectifi post was transformative for me! It helped more than anything else to understand my potential financial future. I've used it when comparing potential jobs, lifestyles, locations. It's been incredibly valuable to me.

I have quite a few friends who have become fans of the tool as well. And I used it to show some friends that yes they can retire with some smart early decisions!

So thank you! I'm glad you posted it on HN and kept up development. I plan to keep using Projection Lab indefinitely to better understand my finances as they develop.

And I do subscribe to the newsletter as well! :) It serves as a nice reminder to check-in.

You can partition a large compute cluster into many smaller ones. Users can make a request specifying how many processors they want for how long. Check out this link to see the activity of a supercomputer at Argonne.

And I believe it is more efficient to have a single large cluster. As there are large overheard costs of power, cooling, and having a physical space to put the machine in. Plus a personnel cost to maintain the machines.

Bio: Graduating May 2022 with a BS in Computer Engineering. Seeking a fulltime role. Most of my experience so far is in systems, operations. I am pivoting to do more software development. I see myself deploying, maintaining, automating, creating compute infrastructure.

I previously worked in deploying high performance computing clusters and research at DOE National Labs and deploying and maintaining a 32 node bare-metal & GPU Kubernetes cluster at my university. Ask about my 70+ page, complete Kubernetes cluster lifecycle, deployment, and troubleshooting guide!

I have a winter break project to port my Kubernetes infrastructure to AWS as a learning experience.

I'm from Chicago, bike year round, have a hobby of fixing my broken bike, and everything else broken in the house. Been getting more into sailing and writing! I love small theater, comedy, and improv.

Yes!

Los Alamos National Laboratory put together a 750 Raspberry Pi cluster. https://web.archive.org/web/20180825200515/https://www.lanl....

If I have my story straight, it was network booted and I believe is source of another piece of software they developed, called Kraken, that helped manage the finicky-ness of a Raspberry Pi cluster. https://github.com/kraken-hpc/kraken

Kraken is a state engine. In the case of the Pi cluster Kraken provided network images, installed and configured nodes, rebooted nodes, and manipulated their state as needed to keep things running.

Another fun piece of research on Pis out of LANL is that at their altitude, 7000ft, they estimate that on average a Raspberry Pi will crash once every 2 years due to bit flips caused by cosmic rays.
