I'll echo what I've already said elsewhere in the comment section. It's about AI! Particularly massive swarms of persuasive AI controlled by an adversary convincing the public to elect bad people with bad policies. Also, companies that rely on ad revenue would love to serve ads only to humans instead of bots.

I think there is an unspoken concern among policy makers about how sophisticated AI is becoming. I think they envision a scenario of swarms persuasive AI bots controlled by an adversary, pushing people to elect bad actors with bad policies. So the main objective isn't to protect the children it is to eliminate anonymity! At some point these age verification requirements will go from answering a simple question to providing your ID. I'll add that there is also an aligned interest with companies that rely on ad revenue as they don't want to serve ads to bots!

I connected two portable LCDs I have that support HDR. Both LCDs didn't automatically detect HDR and looked washed out initially. I had to manually change them to HDR. The signal according to the AVR was...

  Resolution: 4K60

  HDR: HDR10

  Color Space: YCbCr 4:4:4/BT.2020

  Pixel Depth: 12bits

  FRL Rate: ---

...for both the LCDs.

Here are their specs:

  https://www.amazon.com/dp/B08131MVGT

With the HDR off for both the desktop and LCD, the Youtube HDR video at 19s seems flat. I could increase the monitor's brightness to match the planet brightness when HDR is on, but space would be washed out. Of course without HDR, lowering the brightness for darker space results in the planet becoming darker too.

When HDR is off for LCD and desktop I do still see a difference between Youtube's HDR and SDR videos. For example, at the 19s mark I cannot see most of the debris scattering between the viewer and the planet in the SDR video. That should be the case for you too.

*Edit: Strange... one of the monitors states 10bit colors in the link even though the AVR claimed a signal of 12bits. Not sure what to make of that!

You're right! It looks like the Sony UBP-X700 doesn't automatically detect the HDR type and was set to Dolby Vision. I turned it off and the TV now displays the same HDR logo it shows when connecting to the PC. The AVR says...

  Resolution: 4K24

  HDR: HDR10

  Color Space: YCbCr 4:4:4/BT.2020

  Pixel Depth: 12bits

  FRL Rate: ---

...color are now more aligned with the PC. The Blu-ray video seems to be showing more detail in the explosion. I thought this extra detail was because of more color being shown, but I now think this might have something to do with Youtube's HDR video being more compressed.

I'll look into that tomorrow. See my other comment for Linux vs Blu-ray.

Television HDR mode is set to FILMMAKER, OLED brightness 100%, Energy Saving Mode is off. Connected to AVR with HDMI cable that says 8K.

  PC has Manjaro Linux with RTX 3060 12GB

  Graphic card driver: Nvidia 580.119.02

  KDE Plasma Version 6.5.4

  KDE Frameworks Version: 6.21.0

  Qt Version: 6.10.1

  Kernel Version 6.12.63-1-MANJARO

  Graphics Platform: Wayland

Display Configuration

  High Dynamic Range: Enable HDR is checked

  There is a button for brightness calibration that I used for adjustment.

  Color accuracy: Prefer color accuracy

  sRGB color intensity: This seems to do nothing (even after apply). I've set it to 0%.
  Brightness: 100%

TV is reporting HDR signal.

AVR is reporting...

  Resolution: 4KA VRR

  HDR: HDR10

  Color Space RGB /BT.2020

  Pixel Depth: 10bits

  FRL Rate 24Gbps

I compared Interstellar 19s into Youtube video in three different ways on Linux and 2:07:26 on Blu-ray.

For Firefox 146.0.1 by default there is no HDR option on Youtube. 4K video clearly doesn't have HDR. I enabled HDR in firefox by going to about:config and setting the following to true: gfx.wayland.hdr, gfx.wayland.hdr.force-enabled, gfx.webrender.compositor.force-enabled. Color look completely washed out.

For Chromium 143.0.7499.169 HDR enabled by default. This looks like HDR.

I downloaded the HDR video from Youtube and played it using MPV v0.40.0-dirty with settings --vo=gpu-next --gpu-api=vulkan --gpu-context=waylandvk. Without these settings the video seems a little too bright like the Chromium playback. This was the best playback of the three on Linux.

On the Blu-ray the HDR is Dolby Vision according to both the TV and the AVR. The AVR is reporting...

  Resolution: 4k24

  HDR: Dolby Vision

  Color Space: RGB

  Pixel Depth 8bits

  FRL Rate: no info

...I looked into this and apparently Dolby Vision uses RGB tunneling for its high-bit-depth (12-bit) YCbCr 4:2:2 data. The Blu-ray looks like it has the same brightness range but the color of the explosion (2:07:26) seems richer compared to the best playback on Linux (19s).

I would say the colors over all look better on the Blu-ray.

I might be able to calibrate it better if the sRGB color setting worked in the display configuration. Also I think my brightness setting is too high compared to the Blu-ray. I'll play around with it more once the sRGB color setting is fixed.

*Edit: Sorry Hacker News has completely changed the format of my text.

I have Interstellar on 4K UltraHD Blu-ray that features HDR on the cover, Sony 4K Blu-ray player (UBP-X700) and a LG G4 OLED television. I also have an AVR (Denon AVR-S760H 7.2 Ch) connecting both the Blu-ray and a PC running Linux with a RTX 3060 12GB graphic card to the television. I've been meaning to compare HDR on Linux with the Blu-ray. I guess now better than never. I'll reply back to my post after I am done.

AI has risen the barrier to all but the top and is threatening many peoples' livelihood. It has significantly increase the cost of computer hardware and is projected to increase the cost of electricity. I can definitely see why there is a tone shift! I'm still rooting for AI in general. Would love to see the end of a lot of diseases. I don't think we humans can cure all disease on our own in any of our lifetimes. Of course there all sorts of dystopian consequences that may derive from AI fully comprehending biology. I'm going to continue being naive and hope for the best!

I have relatives with property along a river in Bath county Virginia. Across the river stands a ~200ft high cliff with caves that go for miles. I was told that they were formed by the ocean. That explanation bothered me because the caves face west. Now it makes sense! They have also discovered seashell fossils by the river!

The link provided by avree says, "...But the legally accepted norm of 20/20 vision only asks for 876 ppi/dpi at 4 inches!"

A baby's vision is around 20/800 [1] (extremely poor).

> He then told me about an Arabic parable or the like that each child comes with a bag of money.

I can see how an empathetic person having children would increase their focus to succeed, but what is the limit on the number of kids? How would one know when to stop having kids? Why did you stop at four kids? Are you going to have more?

I am not a psychologist, so give careful consideration to what I am about to say.

Have you ever noticed that you can achieve a goal when there is no pressure or expectation? If that is the case, I recommend finishing this semester the best that you can, and then take a one or two year break from school.

Apply your creativity to a project that incorporates some of your education so far. Don't set a deadline, don't tell anyone about it, and don't concern yourself with whether the project can be monetized. Come up with a project that starts out small but can be built onto and improved. A project that can be used later in a larger project is ideal. Don't spend a lot of time researching before you get started; simply start on it. Don't obsess over details; remind yourself that you are working on a prototype, and that afterwards you will be building another one. Take regular breaks from the project and go back over past course materials for ideas in ways to improve your next design. Most importantly, the whole process should be FUN.

The one or two years spent should allow you time to fortify your education and change your subconscious attitude towards engineering. Completing a large project will give you a reference point of what it takes to succeed in the long term.

On the days that I workout in the morning I skip the first dosage.

You need to be very consciously aware of yourself, because it can be easy to forget about yourself. Buy a sphygmomanometer if you don't already have one so that you can regularly keep an eye on your blood pressure. Make certain that you are eating and drinking regularly. Finally, make sure that you are getting enough sleep.

NEVER take more then the prescribed amount; regardless of whether the medication is working or not. Certain foods can dampen the strength of the medication; particularly foods with citrus. The common tendency that I have seen, is to take another dosage because of the perceived lack of effect. This might just be the single most significant reason why people spiral out of control. Regardless of how they feel or perform, the medication is in their system, and by adding another dosage, will cause their tolerance to rise. The rise in tolerance will only make it that much more likely that person will experience the same scenario in the near future.

>We've got it made.

...for now. The bar to entry will be lowered as development tools increase in sophistication, programming languages become more abstract, learning resources become easier to grasp, and children are taught programming at a younger age. In the future we will likely see the market become saturated with programmers. This is not bad for society. However, competition will be significantly higher for less pay. I'm willing to bet that if you're in your 30s (maybe even 40s) you will likely see this play out before retirement.

One possible reason for the cynicism is that an increase in programmers results in an increase in competition for lower pay.

"It sounds like lots of the interested people are more interested in preparing students for a career in software engineering"

That could be the case. Programmers are expensive because there isn't enough to meet demand. If you can get a lot more people interested and entering into the market, the cost will go down. I would imagine an employer would prefer programmer's salary to be more in line with what a typical employee's salary is. If there is an end goal, it would probably be to make programming an expected skill set in addition to a specialty, rather than a specialty in of its own.

Floaters can be a real annoyance. I managed to damage my right eye from over focusing four months ago. I now have a brown floater that takes up about 5% of the right eye's vision. Fortunately it doesn't settle directly in my line of focus, but manages to swing by when I shift my vision. Very distracting. It becomes very noticeable in daylight, as it appears that there are many fine threads connected to it that span the lower quarter of my vision.
