  • That’s really interesting! It shows which communities share users. I am part of jlai.lu, a french-speaking community that is relatively isolated by also slrpnk.net that seems very spread out!

    Would it make sense to compute the standard deviation of each instance’s communities? It would give an idea of which are islands and which are more extended. Not sure if it makes sense to compute it more on 2 dimensions or on the original 21934 though.



  • I’d have a slightly different take: managing things in-house is going to be cheaper if you have a competent team to do it. The existence of the cloud as a crucial infrastructure is because it is hard to come up with competent IT and sysadmin people. The market is offer-driven now. IT staff could help the company save money on AWS hosting but it could also be used in more crucial and profitable endeavour and this is what is happening.

    I see it at the 2 organization I am working at: one is a startup which does have a single, overworked “hardware guy” who sets up the critical infra of the company. His highest priority is to maintain the machine with private information that we want to host internally for strategic reasons. We calculated that having him install a few machines for hosting our dev team data was the cheapest but after 3 months of wait, we opted out for a more expensive, but immediately available, cloud option. We could have hired a second one but our HR department is already having a hard time finding candidates for out crucial missions.

    On the non-profits I am working on, there is a strong openness/open-hardware spirit. Yet I am basically the only IT guy there. I often joke they should ditch their Microsoft, Office and Google based tools, and I could help them do it, but I prefer to work on the actual open hardware research projects they are funding. And I think I am right in my priorities.

    So yes, the Cloud is overpriced, but it is a convenience. Know what you pay for, know you could save money there and it may at some point be reasonable to do so. In the end that’s a resource allocation problem: human time vs money.



  • My point is that using “grokking” in ML is not a Musk/Twitter/Whatever-his-Ai-company-is-named invention, it predates their use.

    Yes the original researchers reused a pre-existing meaning, which has been in internet for a while before. I did not know it came from Heinlein and I did not know its full meaning. I remember seeing it first, more than a decade ago, in a text that explained without any explanation that an isolated unknown word can easily be groked from context. Demonstrating it immediately. To me (and I guess to those researchers) “grok” means “understanding from context” which is particularly appropriate in the context.

    BTW Elon was not the only one to reuse this word. Another company named Groq, totally unrelated to Musk as far as I know, designs AI acceleration chips.
