JesseMeyer··on My mindfulness practice led me to meltdown
Meditation is a blade with no hilt.

I _accidentally_ fell into a vipassana state of mind after the first time trying a particular religious chant, seriously, from out of the pains of boredom as a 20 year old.

At the time I lived nearby mountains, and after 'coming to', I saw them through the window. I cannot describe to you the overwhelming feeling of beauty and awe that crashed over me. It was as though this was the very first time I had ever seen mountains. I think the best description I can manage comes from 'Both Sides Now' by Joni Mitchell.

'I've looked at clouds from both sides now From up and down, and still somehow It's cloud illusions I recall I really don't know clouds at all'

The experience was so disorienting. As if I was seeing the mountains for what they were directly through my senses and not mediated by my knowledge of what mountains were like, linguistically.

It changed my entire life -- weeks later later I lost my job and fell into a 5 year extreme depression / anxiety spell in the attempt to reconcile my adolescent religious upbringing with the continued insight from that experience. Absolutely worthwhile, in hindsight, but it cost me near everything for it.

JesseMeyer··on Remembering Allan McDonald, who refused to approve the Challenger launch
If my personal experience is helpful to those trying to answer those questions then great, but I don't know the answer to them.

I'm at GSFC, and arrogance is definitely not a character trait of those on my team. Earth science may select for a different type of persona.
JesseMeyer··on 2020 Berkshire Hathaway Annual Letter [pdf]
And volatile down is no worry sitting on a huge pile of cash.

Buffet is well known to play long, big, safe, predictable bets, with recent exception with airlines with bad COVID timing. All this is consistent with his personality and history as an investor.

JesseMeyer··on Mypyc: Compile type-annotated Python to C
Where able, but its poor treatment of SWIG makes interfacing with standard tooling a royal pain. In many cases, I've rewritten Numba code in Cython or C for this very reason.
JesseMeyer··on Mypyc: Compile type-annotated Python to C
Scientists are typically not trained computer scientists. They do not care, nor appreciate these technical arguments. They have two datasets A, and B, and want their sum, expressed in a neat tidy form.

C = A + B

Python with Numpy perfectly service just that need. We all have our grief with the status quo, but Python needs data processing acceleration from somewhere. In my view, Python needs to implement a JIT to alleviate 95% of the need for Numpy.

JesseMeyer··on Mypyc: Compile type-annotated Python to C
Python is married to Numpy for scientific computing.
JesseMeyer··on Mypyc: Compile type-annotated Python to C
Cython has first class treatment for Numpy arrays. Can Mypyc generate machine optimized code for chomping Numpy arrays element-wise?
JesseMeyer··on Node.js 14 is over 20x faster than Python3.8 for fib(n)
Most Python data science offloads the data crunching to Numpy, an optimized array based processing library.

This is feasible to reduce interpreter overhead considerably by using array programming:

c = a + b #This is valid Python code.

Where a and b are two same sized numpy arrays. Numpy typically handles the add in an optimized SIMD function.

JesseMeyer··on Factorio 1.1 stable
The game Destiny went this route to increase GPU throughput by 50%. An extra frame of latency, the dev's said, was hardly discernible on a controller.
JesseMeyer··on What Gödel Discovered
"This meant that no formal system, could prove by itself, that it could only produce true statements. "

I see this generalization often, that Godel showed that all formal systems share this restriction, but doesn't the formal system have to be at least be able to express the properties of integers?

Is the ability to formally express integers relatively a particularly demanding constraint on choice of axioms?

JesseMeyer··on How the CPython compiler works
Are you referring to Numba's ability to offload certain loops into a GPU kernel?

Otherwise, Clang has access to the same optimizations that Numba has as they both share LLVM as their optimizing compiler. Beyond that, I think a fairer comparison is C w/ OpenMP vs Numba for parallel processing if syntactic brevity is the metric.

JesseMeyer··on An Introduction to Data Oriented Design with Rust
If a well established abstraction solves the problem, then that's just a particular known about the solution space.

If your data changes, your problem changes. We only ever solve particular problems, given the distribution, shape and density characteristics of input data.

JesseMeyer··on Big Bounce Simulations Challenge the Big Bang
Inflationary theory. Someone more educated on the topic can pine in, but my lay understanding is that the output of some form of primeval radioactive decay (Big Bang) caused a phenomenal rate of spacial expansion, which caused space to expand faster than the rate of gravitational collapse in those first moments.
JesseMeyer··on Mindfulness and meditation can worsen depression and anxiety
A simple 4 note repeating melody of the word, in pieces, 'Hal.le.lu.jah'. Forget where I learned it from.
JesseMeyer··on Mindfulness and meditation can worsen depression and anxiety
I highly recommend as an introduction Alan Watt's 'The Way of Zen', that covers, in great detail, the cultural background, history and practice of Buddhism, in its prominent forms, and its roots in India / Hinduism -- all of which are necessary to comprehend even basic 'traditional' buddhist literature, after having become so institutionalized over the centuries as to have obscure many of the original, and plain to state, insights with now archaic ways of thinking but nevertheless have been maintained essentially untouched.

Then, follow your nose through the bibliography. =)

Oooooooooooooooooooooohm.
JesseMeyer··on Mindfulness and meditation can worsen depression and anxiety
There was no pulling up. And there was no ground beneath my feet. Just an endless ocean with no points of reference by which to orient oneself.

So the only course of action was not to search for rocks to cling to, but of learning how to swim, and dive in. As backwards as it may read, I only felt secure after having let go of myself.

As odd as this description may sound to someone who has not experienced this, it is instantly recognizable to those who have -- which helped discover others who traversed this before. It so happens that Buddhists have a rich tradition for navigating these waters, which helped satisfy my intellectual curiosity of what was happening. To know that I was not 'defective' but merely in an initial stage of 'unlearning' was a big jolt of positively to my psychology.

Ha, thanks for the history lesson. :)
