What models are you using, on what type of codebases, with what tools?

I feel the same way. In general, I prefer working on a couch with my laptop. My eyes aren't great and I end up ruining my posture at a desk, invariably.

Their decision to... use AI for coding?

"...the system described here does it all automatically: It proposes optimizations using LLMs, formally verifies safety properties, shadow-evaluates against real production traffic, and hot-swaps improved code into running services without human intervention or service restarts."

Next up: proportional fonts and font weights?

> To increase the contrast of our sampling vector, we might raise each component of the vector to the power of some exponent.

How do you arrive at that? It's presented like it's a natural conclusion, but if I was trying to adjust contrast... I don't see the connection.

Maybe try finding a software engineering job at a place that also uses your scientific expertise. You may be able to find or create opportunities there. The position might not exist, but you can maximize your chances of something coming your way that needs both skill sets.

In what sense? I'm a newbie, but curious because I'm working on stuff related to https://mesastandards.org/mesa-der-std/.

chrisra — Fri, 10 Nov 2017 18:02:02 +0000

Absolutely not. It's not like there isn't a million other images that work just fine. It's a symbol (even if most people don't know) of the objectification of women, that is pervasive in a field that struggles enough with treating women fairly.

One of the "Hello, World" applications would be learning to classify MNIST digits. They have a tutorial on their site.

These communities aren't exclusively for Mormons. I think k he said gay people could hold some kind of leadership position.

Not sure what's implied by commune, but it seems like he welcomes people of other faiths in the community, even in leadership positions.

I have an MSI with Linux and Windows on it. I prefer to do everything in Linux and mostly only use Windows for games.

I'm a programmer, and working in Windows sounds kinda scary to me.

I don't think your question deserves the down votes.

And instead of writing MCMC samplers yourself, with probabilistic programming languages you can define a model and the language figures out how to do the sampling for you.

Pretty close to how I feel. It's not about the money - it's about personal progression and impact for me.
