I was reminded of this MythBusters episode: Tesla's Earthquake Machine https://www.youtube.com/watch?v=LHsHiKtjoag https://www.youtube.com/watch?v=LHsHiKtjoag

So classic. For those weary of random links, it’s Cantrill and Gregg screaming at Thumpers and affecting IOPS. That was such a great machine. We rearchitected our systems around it.

  random links to a youtu.be video? pray tell, what malware would be transmitted from youtube.com, owned by Alphabet?

    It's not about privacy or malware, although those are important in life. Maybe I'm on Reddit too much, but I like knowing what will appear on the other end of a link. I originally posted my own comment with link and prose, but then saw GP's comment which preceded mine by an hour, so I deleted mine. I didn't originally realize it was that same video because it didn't say so, but then I recognized the link hash. I want people to see that video, because it's so great, so I added context as a reply.

    You could catch a bad case of algorithm poisoning if you're not careful

    Someone linked flesh simulator the other day and now my you tube is filled with some seriously weird stuff.

  >it’s Cantrill and Gregg screaming at Thumpers and affecting IOPS. For me, that is less meaningful and more random than a youtube link. I have absolutely no clue what you are talking about.

    That is fair, particularly compared to Janet Jackson! I will add detail. In their younger days, two distinguished engineers, Bryan Cantrill and Brendan Gregg, made this video where they scream at a data storage server nicknamed Thumper. Screaming at it has surprising results, which are observed with a novel software technology called dtrace. The Sun Fire X4500 was a dense storage sever, 4U with 48 disks and insane IO performance and a newish filesystem called ZFS. The video is not only funny in content, it features technology and technologists that became very impactful, hence the classic tag. --- I love the lore, so I'll drop more. While our team previously used AFS (mainly for its great caching) and many storage servers, this hardware combined with its software allowed us to consolidate and manage and access data in new ways, alleviating many of our market data analysis problems. We switched to NFS, which previously was not performant enough for us on other hw/sw architectures. While using NFS with the Thumpers and then Thors (X4540) was fantastic, eventually the data scales became hard again and we made a distributed immutable filesystem that looked like the Hadoop HDFS and Cassandra file systems, named after our favorite Klingon Worf (Write-Once Read-Frequently). Interestingly, in 2025 both XTX [1] and HRT [2] open-sourced their distributed file systems which are pretty similar to it, using 2020's tech rather than 2000's. HRT's is based on Meta's Tectonic which is a spiritual successor to Cassandra. I wrote about our parallel HFT networking journey once upon a time on HN.

      It was your rather odd usage of "affecting" that caused my confusion, made me think IOPS was some new internet acronym and something which could be affected as one would affect continental to sound cultured. I would have gotten the general gist had you said "causing IOPS" or if I knew Thumpers or maybe if you had used the full names of Cantrill and Gregg but I am not sure if I would have made that connection. Thanks for the clarification and the absolutely bizarre and quite interesting construction, I enjoyed this a great deal. Edit: I clearly just got derailed by my initial confusion, there was nothing weird about your usage.
