choxi··on New GPT-3 model: text-DaVinci-003
It looks like only the model was updated, the training data only goes up to June 2021 (same as davinci 2 I think).

But GPT-3 came out in May 2020 so it should be “self aware” already.

choxi··on Anti-War Speech Sent Eugene V. Debs to Prison, 1918
Do you mean this? https://www.federalreservehistory.org/essays/panic-of-1907

Because that name is also used to describe the event, wasn’t sure if you meant a specific book or article.

choxi··on Stable Diffusion 2.0
Here’s a comparison study on Reddit: https://www.reddit.com/r/StableDiffusion/comments/z3ferx/xy_...

It does look like artist names have a significantly reduced effect.

choxi··on Stable Diffusion 2.0
Mixing artist names was by far the most effective way to create aesthetically pleasing images, this is a huge change. DreamBooth can only fine-tune on a couple dozen images, and you can't train multiple new concepts in one model, but maybe someone will do a regular fine-tune or train a new model.
choxi··on Is our definition of burnout all wrong?
I’ve always thought burnout is the same thing as learned helplessness, which is a pretty well studied phenomenon in psychology. It doesn’t seem mysterious to me that if you repeatedly do a task that is unrewarding for long enough, you no longer want to do it. Then the COVID burnout can be explained by a large scale reduction in the rewards that typically keep people going.
choxi··on Betting on things that never change (2017)
I think maybe the fundamental hard thing about startups is that you can’t ignore the problem space or the solution space. It’s not like Bezos was passionate about selling cheap books for years before Amazon, he saw that this new Internet thing was going mainstream and building on top of this new tech was the premise of the business more than selling books cheaply and quickly was.

Most of the startup opportunities in the last couple decades were built off the back of several deeper tech breakthroughs like mass mobile phone adoption and virtualization. I think more founders have been successful just riding these tech waves than sticking to a problem space. Brian Chesky didn’t work in hotel management and Travis Kalanack didn’t work in transportation. They were just familiar with cutting edge consumer tech and applied it to problems they had no familiar with before they started.

choxi··on Observations from our Joe Rogan Experience experience
I think the overpolished and analytics-driven media personalities left a vacuum for an authentic voice to fill. Someone would have filled it, and it happened to be Joe. It’s not like someone sufficiently motivated could repeat his success trajectory, part of it is always being in the right place at the right time too.

I love this, there are so many interesting questions and challenges in the area of how humans will interact with AI. To me the correct model is to think of intelligence as a resource like compute as opposed to a personified computer, which opens up the opportunity for so many more applications.

An example is the recent text-inversion paper where they found a way to extract the embedding of a visual concept from several images. Or how Midjourney is able to somehow integrate their model with StableDiffusion to get the realism and control of SD but the aesthetics of Midjourney.

Basically, it seems like deep learning networks are a lot more composable and controllable than I would have expected, while still demonstrating really interesting features. There could be entirely novel neural net architectures with no analogue in the human brain that still do really interesting and useful things. It’s exciting to see what people are coming up with!

choxi··on Why I quit using SwiftUI
You can integrate UIKit into SwiftUI, I always found that to be a pretty general purpose fallback on any missing functionality in SwiftUI.
choxi··on From maximum force to physics in 9 lines – and implications for quantum gravity
Are the claims about the shortest distance, maximum force, and shortest instant of time all undisputed? Makes the universe seem really discrete and simulation-y.

choxi··on Swarming drones autonomously navigate a dense forest
Art imitates nature. All ideas are remixes of previous ideas, and ideas are ultimately rooted in observations from nature. A human mind in a vacuum wouldn’t be able to create anything.

choxi··on What Artists Notice
I used to think the cliche of the “sensitive artist” meant that artists were more emotional or dramatic. I see it now as they’re literally more sensitive, as in the mental experience of their senses is higher resolution or prone to intense focus. I wonder how much of genius or talent is a sort of trained sensitivity.

choxi··on How Video Streaming Processing Works
Does all the 1.7GB of the decoded video get copied to the GPU? Or is there some playback controller that knows how to read the “delta format” from the codecs and only copies deltas to the framebuffer?

It still blows my mind that we can stream video at 60FPS. I was making an animation app that did frame-by-frame playback and 16.6ms goes by fast! Just unpacking a frame into memory and copying it to the GPU seemed like it took a while.

choxi··on Obstructive Sleep Apnea Is Associated with Low Testosterone Levels
I had mild to medium sleep apnea where for a couple years I was probably only sleeping 4-6 hours a night. One day I separated my shoulder playing football and the only way I could sleep was on my back, but this made the sleep apnea much worse and I was probably getting 3-5 hours for several months. I caved and went through the tedious process of getting insurance to cover a CPAP machine. It was awful though and I slept worse while using it.

Meanwhile, the orthopedist I had seen for my shoulder suggested I try to correct the hunch I've developed from sitting at desks so that my shoulder doesn't heal in an awkward position. I had been doing that and noticed that every once in a while, I would sleep perfectly fine and wake up fully rested. This made me suspect this was a fixable problem and not some permanent feature of my anatomy.

After ~6 months of exercising and stretching to fix my shoulder hunch, I could finally sleep through a night and today I get better sleep than I can remember having in many years, without the CPAP. If you think you have sleep apnea, I'd recommend checking out r/posture on Reddit to see if you might have poor posture first. It can be really difficult and uncomfortable to fix if it's been developing for ~10-15 years like mine, but it's so worth it and there are a lot of other nice health benefits that come with it.

choxi··on The Reign of Introverts Is Here
Is there any good research to support "introvert vs extrovert is more determined by where you get your energy from" or is it just one of those folk wisdoms like power posing and ego depletion?
choxi··on Future from a16z
This would be cool if they added a prediction market on top of this. It doesn't necessarily need to be a market, but I would love to track falsifiable predictions that journalists make so I know which ones have a track record of being correct.
