I'm guessing the longer term interest Amazon has is to use these stores to generate a dataset for their computer vision system, which they could license as a loss prevention technology to other stores

Thank you for voicing this, I really agree that something about the culture growing up around tiktok is special and feels like a breath of fresh air. I think a lot of the doom and gloom talk is coming from people with a totally outside perspective who haven't actually tried to engage with the platform.

One thing that stands out as special to me, since it started out as an app for dance videos, so much of the cultural threads still revolve around that, and so it encourages an embodied way of presenting yourself. It makes text heavy sites like twitter and facebook feel... detached, cerebral, sterile in comparison. Whereas tiktok keeps a playful frivolity that that is so often lacking online. It seems to me a big step towards solving the big challenge with "online culture": considering the human.

This is in Seattle, on 5th ave. The concrete pillars are the monorail track. The street confused me driving as a human sometimes. There are more videos of the Tesla software being confused on this particular street floating around

I worked in a CNC shop for 6 years and never once heard "G programming language"

Interestingly enough, this isn't a mess in the shell's own builtins. The [ ] expression syntax is provided by the program /usr/bin/[ which is (often) a symlink to /usr/bin/test. It's just a clever trick! [ is a program that evaluates it's argv as an an expression, less the trailing ], and then returns the result as an error code.

Actually re-reading your post you probably know that already! Nevermind then. Maybe someone reading this will be enlightened

I thought it was pretty clever!

iMessage has read receipts, faster and more reliable delivery, higher quality images/videos. More than just the color of the bubble

Just run a Linux hyper-v vm. That's what WSL2 is doing under the hood anyway. I run it this way and it's great. I have windows terminal auto ssh into it. Performance is great. And using the X server x410 on the windows side gui performance is fantastic (though no hardware acceleration) because instead of ssh tunneling x410 suports AF_VSOCK for the x socket, which hyper-v supports for performance as good as a domain socket on the same machine.

Got a link to read more about this?

There is a huge amount of these $20 bills lying around in fact. The thing is they're not that easy to pick up. These ERP systems are often fairly bespoke, designed for the workflow and needs of specific industries, or even specific niches in industries.

I work for one of these bespoke ERP companies, our niche is CNC machine shops (huge industy you don't hear much about). Our software was grown organically out of tools we made to manage our own CNC shop, spun out into its own company. That deep domain knowledge is what allows us to make a competitive product.

Well it shouldn't make a difference in practice because everyone knows exactly how far away the halving is and makes their financial calculations accordingly

What differentiates x410 from other x servers is that it support communication over VSock, which Hyper-V supports, and it's probably 3x less latency than tunneling x over ssh. Made it possible for me to comfortably use emacs in my hyper-v arch vm

Weird to see my tiny hometown (Lynden, WA) was used as a test market

Your entire withholding from 2019 would be returned as a tax refund, thus the cash

For a very nice into to constructive math, see this[0] link as well as some good HN discussion here[1].

The photon has some amplitude for reflecting in all possible directions, it happens that for certain directions these amplitudes are very close to the same value and so reinforce and become more probable, and at wider angles tend to cancel out and become less probable. When this is not the case and wider angles instead reinforce you can observe this directly in for instance a diffraction grating.

I don't think finitists have a problem with convergent sequences, they just wouldn't talk about infinities, rather than extending the sequence gets you as arbitrarily to 1/3 as you wish to go

Take a reasonable dose (~100mg), avoid physical activity, and take a proper supplement stack [0] and you will find no hangover but actually a mild afterglow.

I've heard of synthetic Ritalin analogues (isopropylphenidate). There is something similar for Adderall?

Besides the obvious answer of medication, which I've personally found very helpful, I think physical movement is the biggest thing for me for staying engaged. I just can't focus on things while sitting still which is obviously really rough as a programmer. I find that as soon as I have the urge to spin my wheels checking HN or tinkering with my emacs config or some other comfortable distraction I get up and take a walk, preferebly outside, in a way that makes my brain notice it's in a different space, then visualize myself working as I return to my desk.

Perhaps you're thinking of the i-Opener?

I'm the one who provided the third quoted anecdote in the article. What I didn't mention was the HPPD coincided with a sort of depersonalization/derealization effect. Basically I got very checked out from my own life. I felt as if I was a spectator watching my life happen and I didn't really feel any connection or agency towards anything coming into my sensorium. It was a really weird and hard time for me. Those feelings as well as the hallucinations came and went together for me. After about 1-2 years I was completely back to normal. During that time I still microdosed occasionally, but that didn't seem to have any effect on those symptoms either way. I didn't have experience anything like that until I took pretty large doses (>200ug). I was taking 100ug doses on a regular basis without having any lasting effects, it appeared to me that the high doses came with the aftereffects. I also didn't experience anything like that with psilocin (mushrooms). I'm willing to answer any questions about my experience if anyone has any

Is there anyway to assign a reasonable conditional probability to those Xk's and recover some useful science?

A closer mathematical operation would be unitary matrix multiplication

The $/W/Block profile is where the security comes from. Insofar as a miner can spend dollars to increase their chance of getting the block, they will, until MR=MC. See this article which explains it very well, though it is talking about PoS: http://www.truthcoin.info/blog/pow-cheapest/

Here's a cool link I just found going over this exact scenario: https://www.mathpages.com/home/kmath530/kmath530.htm

Interesting to note, the napkin creates a uniform gravitational field above and below it. Meaning that the force applied to an object is the same regardless of how far away it is from the napkin! That force is 2pi * G * m * rho where rho is the mass density of the napkin.

Indeed, if it wasn't flat it would not perfectly cancel.

The drop off applies because the force of gravity is proportional to 1 / distance^2, so in this case the napkin would still have infinite mass, but it would not have infinite density, so if you took a surface integral of the gravitational force provided by each point in the napkin, over the whole napkin, it would converge on a finite value, as each point contributes less and less force as you get father away.

How can an infinitely large napkin have a center of mass? It seems to me that all everything would get sucked on a trajectory normal to the napkin's surface. Any horizontal force would get cancelled by an opposite force, at an opposite point on the napkin. Also, force of gravity drops off with the inverse square of distance, so the force would have a finite value, depending on the density of the napkin. Similar idea to a common homework problem for introducing electrostatics: calculate the electric field generated at some point by an infinitely long wire with some charge density.

I believe the area between the dotted and solid lines is a mirror. The blob of light is visible because it's passing through some medium that scatters it, then when it disappears it has been absorbed by the mirror, then we see it reemitted shortly after.

If we knew Magic was limited to N states, then we can conclude that a program running on the Magic Turing machine will never halt if it has not halted after BB(N) steps.
