    The author explicitly mentioned syncing to his parents house. Even the "RAID is not backup" should be more nuanced IMO once you are talking about FS that supports regular snapshots…

    It is especially strange not to see it in the list given GiTS is heavily featured (according to the comments, I can't access the page or web archive ATM). Patlabor movie 2 was dire…

    The metaphor breaks quickly because as a first approximation the electricity "quality" does not depend on the provider, and will not change overtime. That's not true of LLM output.…

    For NumPy/Pytorch, the C API is much bigger issue than pickle. I have not looked at the architecture of this, but given it uses its own IR + replaces ref counting w/ a GC, I am ass…

    The same way cloud is about doing the exact opposite. Understanding a bit of accounting / corporate finance opened my eyes to many things.

    That's debatable. We can't go back in history, but if it were not for ML/data science, I believe python 3 would have killed python. At that time web dev / CLI utilities were major …

    Also NI, etc. was very linked to the scene from the early days. Cubase, etc. have no such link that I know how, but there was still the strong hacker culture around atari and to a …

    I wanted to understand the implementation of some numerical algorithms, and the tech reports were not enough. I cloned the repo of said library, gave it claude and asked it to writ…

    Partially a mix of strong, hacker culture in Germany in the 90ies + Berlin being a major place for electronic music in that decade. For example, ableton was famousley co-created by…

    Not really. GPU many cores, at least for fp32, gives you 2 to 4 order of magnitudes compared to high speed CPU. The rest will be from "python float" (e.g. not from numpy) to C, whi…

    scilab is not based on numpy/etc. However, matlab was certainly an inspiration for the scientific python stack in early 2000s. I myself started contributing to numpy and matplotlib…

    A fifth edition has been out recently: https://shop.elsevier.com/books/programming-massively-parall... I started learning about GPU and CUDA from this book recently, and I agree th…

    The main point of mythical man month was that communication cost across people was the main cost as project grow in complexity. So increasing individual output by itself is not eno…

    Indeed. I would add a third factor to compute and datasets: the lego-like aspect of NN that enabled scalable OSS DL frameworks. I did some ML in mid 2000s, and it was a PITA to reu…

    Also one of the initial creator of haproxy, a well known reverse proxy. To imply somebody like as a simple "AI shill" is just ignorant.

    I agree. It is difficult to convince leadership to do this work at all ("it works on my example, ship it"), and in my experience most DS don't even want to do it. One of the key va…

    The typical solution is to work in one of the "global" (aka American) companies in Japan: google, amz, apple, ms, etc. At least for now there are enough jobs across all those compa…

    Yes, this is the real cause, and the OP explanation is just a symptom of that.

    My rule of thumb is that management complexity is given by #direct reports x #project, where project is defined as a set of stakeholders (be it PM, etc. depending on business). Con…

    I can believe it is deliberate at the top, I've certainly seen first hand in several orgs I've worked at. My sense is that unless actively managed against, any org big enough to ha…

    You had to accept some license terms before you could download the VST SDK. When linux audio started to get "serious" 20 years ago, it was a commonly discussed pain point. Concrete…

    I agree the big deal is tool calling. But MCP has at least 2 advantages over cli tools - Tool calling LLM combined w/ structured output is easier to implement as MCP than CLI for c…
