I own a bottle of this stuff, and it's not really as amazingly black as it looks on camera. Sure, it's pretty damn black. But it's easy to see the imperfections and stuff up close. There was a video that compared it to black felt, which is pretty similar.

And no, this is not Vantablack. It's just some special acrylic that can hold a lot of black pigment, and a lot of black pigment. Vantablack needs to be "grown" with high temperatures so its usually seen on aluminum foil and such.

Overall, this is pretty cool. I could definitely believe that it's the blackest acrylic paint in the world. However it doesn't create a "black hole" or anything.

There are already pretty advanced methods for crime detection like that one thing where they show pictures of various objects while measuring brain activity to determine if you've seen the specific object before. Not sure if that tech is actually deployed though.

I'm just wondering, do advertisements worth that much?

Surely brain computers will be a pretty big investment for people; would embedding advertisements be worth it for companies? I'd imagine most people are willing to pay another few thousand dollars on top of the very high cost to avoid any sort of obnoxious features, for both personal and potentially socially-influenced reasons.

It's hard for me to see how anything could be worth more to companies than straight profit.

There is only a tiny bit of lithium in lithium batteries, afaik.

Just wondering, as someone currently preparing for SAT - why is it so easy to drastically improve one's performance on standardized tests if they predict IQ? My score was pretty mediocre (due to a year of slacking off during COVID) but after some practice I improved it significantly - does that mean my IQ is greatly increasing as well?

I know of some very, very clever people who do not perform well, and the opposite too.

I'm not sure why this post is flagged and dead. This seem like a genuine and constructive question.

I'm not sure about AGI. You can just control the robot remotely from earth. Sure, there will be a minor lag but definitely won't justify need of AGI.

Is suppress sneezing something unusual to be learned? I always thought that you can just not sneeze... I remember as a kid, when I noticed a sneeze was coming, I just decided that it was too much work, for whatever reason. Maybe I didn't want to find tissue, or maybe I didn't want to make noise.

Probably not? When I use my headphones with my laptop, 10% system volume and 100% app volume is about comparable to 80% volume (ish) on my iPhone 6S.

Evidently there isn't much standardization between devices. Personally I don't find it that annoying - devices remember what volume I last set them to.

It might be due to your headphones, if they're particularly low resistance.

If you scroll down a bit further, you can find some pictures of rooms that people actually use, instead of the flooded and decaying rooms. Looking at the compact and efficient setups of those residents, I actually thought it seemed kinda cozy.

Thank you so much for pointing out fx-115ES PLUS2! I looked for a good hour yesterday trying to find an alternative to the fx-115ES PLUS (first edition) with the same features, after Casio discontinued the original. I'm honestly embarrassed that I had overlooked this...

I do absolutely agree that Casio calculators are just wholly better than TI in general. Their menu driven interface is a game changer for me back in middle school. TI-36X Pro felt cumbersome and confusing, while fx-115ES was much more intuitive.

That's a good part thanks to the fact that nobody other than RPi Foundation can get those Broadcom microprocessors for cheap. This fact really sets apart the money making ability of those two companies.

I think he's referring more to the Arduino/Genuino ecosystem rather than solely the Arduino company itself and its products.

I tried this with a more technical prompt... and what can I say? I'm stunned at the incredible command of jargon here. It's even mostly correct with the actual technical details at a glance, especially that description of how radar works! I can't wait for those research paper generators to use stuff like this to make high caliber fakes.

Prompt:

> Synthetic aperture radar imaging is an effective method for

Results:

> Synthetic aperture radar imaging is an effective method for detecting the presence and/or quantification of target objects, including: detection and tracking of moving targets, which are known to be difficult with visible imaging and/or laser radar; monitoring the occupancy of an enclosed space, such as a room, by the presence of occupants therein; and detection of moving objects, including animals and pedestrians, as well as people. A radar device is composed of an antenna, a receiver, and a transmitter. The antenna radiates a beam of energy (e.g., electromagnetic radiation in the radiofrequency range) that is received by the receiver. The transmitter then transmits an interrogating signal to the target(s). The time delay between transmission and reception at the target(s) is used to measure the range of the target(s) from the radar device. All targets in the field of view of the radar device contribute to the signal received by the receiver. The transmitter amplitude and/or phase modulates the signal transmitted to the target(s) with the information to be encoded, typically at a much higher modulation rate than that used

Another prompt:

> Fringe fields in microstrip patch antennas

Results (shortened by me for brevity):

> Fringe fields in microstrip patch antennas and their RF performance

> 1. The microstrip patch antenna is a conventional patch antenna that is created by a thin layer of insulating material placed on top of a conductive substrate. The antenna is excited by a current in the conductive layer in the vicinity of the antenna.

Now I have a question. How does this GPT-J know what a patch antenna is? It's able to give an almost correct description of this rather technical device. It made the mistake of flipping conductive material and insulating substrate, but it's very close. Does this neural network have the "knowledge" of a patch antenna in the weights? How does that even work? It seems kind of incredible.

Yes, we still use chromebooks in high school - though most of my friends have nagged parents enough to get their own laptops - me included :)

They all got "enterprise enrollment" feature that makes them kinda useless. Pretty much impossible to reinstall OS, and believe me, lots of people have tried.

I heard rumors (friend of a classmate of a friend) that some kid was able to get their older brother to help wipe the boot memory chip or something to get rid of it. Nothing reasonable for non experts that I know of

Not sure if the "3d bio printer thing" that you're thinking of can synthesize stuff at the molecular level though. Maybe it would be fun to have it print scale models of the chemicals with colored filament.

This sucks. My school district used a bunch of money to buy every student chromebooks. I remember just a few years ago, back when I was in middle school, I helped unbox all the chromebooks that were shipped to the school - about 2500 of them. Just for one middle school. Every student having access to these laptops made some thing a lot easier, like using Canvas to submit work done on Google Docs.

However, this is in fact a real problem. Our district forced very obtrusive monitoring and blocking software, as well as literal bloat to be installed on the chromebooks - there's like 20 browser extensions that cannot even be turned off, making the already low performing chromebooks so laggy that it's hard to use. Obvious "bad sites" like pirate bay, porn, and etc are understandably blocked, but they also block access to "social media" like reddit and discord.

This doesn't sound that bad yet. The problem comes when students use their own devices instead of the school provided ones. Some sites and services are still blocked at the internet level, but can by bypassed easily. This means that, students with own laptops could communicate with each other using services that chromebook students cannot access. This means that students from families with lower income or with more siblings literally get blocked out of friend groups, with access only to heavily monitored google chat. During distance learning, this problem has only been made worse.

Additionally, district chromebooks are absolutely no less distracting with the various censorship and monitoring and bloat - kids would still much rather browse the limited internet than pay much attention in class. I think there was some study that showed laptops drastically reduced student's academic performance on average. (Though I think access to computer is really powerful for learning how to access internet resources and developing actual knowledge.)

TLDR my opinion and experience on technology + kids

I second this. Most people I know, including myself, would much rather have one time purchase.

I'm curious, do you happen to have any stories and stuff to tell about him? (Hope you live on the first floor so you can still use the defenestrated laptop)

What are exceptions to listening? I'm pretty sure you can listen wherever and however you want.

Or use better engineered hardware. HackRF One had some very weird hardware designs that don't perform well for the price.

I don't think inkjet printers have anywhere near enough resolution to get WiFi/BT or even NFC tags - those things are incredibly complicated. I expect it would also take a whole bunch of engineering to get the printed ink perform well at such high frequencies

This is pretty much what they do nowadays. Look at patriot or S-400: the launcher, fire control radar, acquisition radar, are all mounted on trucks that can drive around. The radars do indeed share information with other assets like that. However anti radiation missiles ("ARM") are still a threat as the system won't function if all the radars are out

How the hell can they get all these bits of humans for so cheap? As much as I love high value chinese stuff on amazon this one sorta creeps me out

What does "as paranoid as turning your back to a camera and the eyes reading very primitive algorithm will shut down your PC" mean?

Is there a way to somewhat reliably derive time based on life cycle of bugs? Any particular species that have weird quirks which could be exploited like this?

I think we can agree the impacts are less.

Also a good tip to touch things with the back of your hand first, as the current can't force you to grip harder. This is more for line connected stuff though.
