plenty of weird and tough things about getting older but one thing I really do love is not knowing what the hell people are talking about. I love not being bothered w/ stuff. "Alex Cooper's beverage business is failing." I don't know who that is or whether that's good or bad. you kids have fun

there's a lot of what I would just call "expertise" or "experience" that lead me to get very frustrated with LLMs sometimes. Today's example: generating basis spline fit for me (great use case bc I hate spline boilerplate). But I want to set knots that go outside the range of X. I get an error...

do I know any data engineers or software devs who work on research tech? There will be some hires on my old team working with our research platform / financial market data pipelines / distributed compute etc. Crazy data and very cool tech where Python meets high-perf C++

It's perfectly fine to have a principled commitment to empiricism and scientific discipline, actually. And when political actors try to bully you into being quiet or changing your story, it shows your integrity and bravery to resist that pressure. Right or left.

fixed your headline
A hit song on the Billboard 100 charts is termed *$k$-good* if it is _ever_ in a weekly top-$k$, and *$k$-immediate* if it _debuts_ in the top-$k$.


An artist is *$(n,k)$-Olivian* if their $n$ first $k$-good hits are all also $k$-immediate.

*Headline 1.* Olivia Rodrigo is the first $(10,10)$-Olivian woman.

This blog post does not render in quarto without a Jupyter kernel for Hy. There is such a thing already but it's old and broken. LLM diagnosed and rolled its own kernel adapter for Hy in like 3 minutes. It is shipped with the blog post's src code so you too can feel the Hy of lisp programming

I like language exercises like these, so I implemented some of these functions in Hy, which is a Lisp that generates Python. We like functions right? Would we still like functions if they were **evil**? mikedecr.computer/blog/r-hy/
hy code and output: 

(import toolz [first second])
(require hyrule [->])

(defn which [lst]
  (-> lst
    (enumerate)
    ((curry filter (compose bool second)))
    ((curry map first))
    (list)))

(which [False False True False True])

I still believe it's a mistake to believe that the fact that LLM capability along certain dimensions seems to increase with scale implies that a sufficiently large LLM can do anything imaginable. Or that if an LLM can perform a task with difficulty D, it can do anything with difficulty ≤ D.

I love the conceptual model of ggplot but believe that implementing the exact syntax feel in python is not desirable or important. The "adding" of the plot components... how much will you suffer for this? I write this helper fn all the time
python code snip:

from pick_your_ggplot_emulation_pkg import *


def fnplot(data, *args):
    return sum(args, start=ggplot(data))


fnplot(
    data,
    aes(x="x", y="y"),
    geom_point(),
    geom_line()
)


# vs...
(
    ggplot(data) +
    aes(x="x", y="y") +
    geom_point() +
    geom_line()
)


# or...
ggplot(data) + \
    aes(x="x", y="y") + \
    geom_point() + \
    geom_line()
