It is not accurate to say that PTP is a predecessor to NTP.

You need both.

PTP synchronizes clocks to a ridiculous precision, like down to nanoseconds. To do that, it uses support in the ethernet hardware. Hardware adds precision stamps to the PTP-related ethernet frames, so that the time calculations are free of jitters induced by the higher network stacks.

A cool thing is that PTP-aware routers/switches can actually rewrite the timestamps in PTP packets to subtract their own propagation delay accurately.

Something in the network has to use NTP, if it is important for the devices to have the correct calendar date and time; you don't use PTP over the Internet to get time from a remote server.

The real-time clock being synchronized isn't even the system clock in the first place, but a high resolution RTC that is in the network adapters and switches.

As an additional utility on top of the PTP stack, there is the possibility of synchronizing the host system's clock with the help of PTP.

PTP is used for things like generating precise signals in certain applications. E.g. Some devices that have PTP support can be programmed to generate periodic pulses which are clocked by the sychronized real-time clock. With PTP, two such signals from separate devices on the network can align very precisely. Such an application doesn't care about the time of day, just that the signals are synced.
Perhaps I'll have to make a HN post just for that some time :)

> Why not buy the movie you want to watch (so that the creators get paid) and then torrent an .mkv you can play anywhere and keep forever?

This is exactly the approach I've taken for the HD era and it works great.

Back in the DVD era I had a well optimized ripping setup, I put hours in to tuning everything so I could pop a new disc in and have it ready to play on my Windows Media Center instance as quickly as my drive would read it.

At this point though, it's just not worth the trouble. Especially for UHD content, ripping that is just a nightmare. These days when I buy a new disc I just add it to a list on my server and my server goes out, finds whatever quality copy I told it to look for, downloads it, extracts it, names it according to my standards, and tells Plex to update its metadata.

More often than not by the time I get home the content is already there on my server waiting for me and I can toss the disc on the rack for display purposes. In my last move I had an entire box of discs that were still sealed in their original plastic.

It's the best of all worlds. The content owners get their money, I get a DRM-free copy that I can play on what I want when I want. It's not strictly legal but it's morally clean. The end result is the same as if I had ripped it myself, just with less effort on my part.
Are there any streaming services that distribute these? It would be a shame if they were lost to locality.
High refresh rates start to make sense given that "DLSS 3" frame interpolation is coming.

Frame interpolation can't help low framerates. At <= 60fps any extra lag and interpolation distortions are noticeable. OTOH faking 120fps -> 240fps adds little latency in real terms, and will have less movement to compensate for. Then it changes question from why bother using 240fps, to why not if it's basically free?

To be fair, NASA _is_ probably reviewing the high res imagery before releasing it, but for a much more mundane reason than any conspiracy theory. A lot of contractors worked on Orion. NASA is responsible for not accidentally leaking any trade secrets that may be visible in imagery.
I believe Madoff was sentenced so long to set an example. He was going to die in prison or be incredibly old when he would have got out regardless. His brother is out of prison now. Were any other people in their orbit sent to prison?

We have people in prison for life for 3rd time marijuana charges. We are still putting people in prison for long periods of time for repeat non-violent offenses. Imprisoned populations are disproportionately of certain demographics. Many see all of this as a sign of classism and racism.

The challenge is that if a discrepency is shown, how do you know who is lying? The whistleblowers or the CT log vendor? A consensus mechanism built on top of the log would be able to show the 'history of the history' to enable folks to make better determinations on who to trust or not.
If you compare the economic costs of public transport and “cheaper” housing to WFH’s requirement of an internet connection, it’s much more cost effective to work from home. Now we could say that face-to-face interaction outweighs these costs economically, but you’d need the data, and at least in terms of commuting you’ll never beat the ecological footprint of not going anywhere.

Can you expand on that a bit more? Do you think that more open source business models will lead to more rehashing of the same code/concepts over an over again?

I'm also curious how you think this may apply to the rise in AI coding projects. In theory, it will become possible to create complex software by simply describing it well, and much of that code from the AI training is open source.

There were 3 major pain points for me:

* USB access is more difficult than just plugging something in.

* Debugging tools like perf, RR, etc were either unsupported because they needed hardware counters or required custom builds (no system headers in apt to help either).

* The VM takes a lot of disk space.

The rest of the experience was fairly smooth. WSL2 can access the entire filesystem through /mnt/<drive letter>/. Windows -> WSL is a bit janky, but it works. GPU access is supported. Network access works. You can use a remote X session to get GUIs working, though you need to be comfortable with linux. Unfortunately having DISPLAY set caused pip to hang for long periods due to [1], but apparently that's been resolved.

All in all, it mostly replaced my windows usage by the end. It's also a great workaround for legacy IT environments where the system is configured with Windows and only Windows.

You're describing marketing, and marketing of an idea is important - I agree.

However, you also need to have a population that cares about science, engineering, exploration, etc. I don't believe what gets people into engineering and science is because of how engineering and science are marketed. It certainly doesn't harm anything by marketing it, my opinion is that it is a small component of the overall picture.

To me, these sounds produce fatigue. When I used to travel frequently by air, I had a habit of wearing noise-cancelling headphones just to try to suppress the background, whether or not I actually played any other media over it. I didn't really like the leftover hiss, but cutting the deeper sounds seemed to reduce my fatigue anyway.

So, I am wondering how brown noise fans find the noises of travel. The different synthesizers posted in this thread overlap a lot with highway and airliner environments for me. Different vehicles had different equalization, of course.

Another sound this reminds me of is the old background rumble they put in the Star Trek Next Generation TV show to represent their shipboard environments.
Actually, I strongly disagree. Ideally, it would not be in the air in the first place. Failing that, once it's in the air, I personally prefer that it go to the intended target rather than just kind of wherever it ends up.

Music theory is an amazing subject. You can actually make random notes sound reasonably musical by constraining them to just a few simple rules. Copy/pasting from Dmitri Tymoczko's Music 105 lecture notes:

1. Conjunct melodic motion. Melodies tend to move by short distances from note to note. Large leaps sound inherently unmelodic.

2. Harmonic consistency. The chords in a passage of music, whatever they may be, tend to be structurally similar to one another.

3. Acoustic consonance. Some chords sound intrinsically good or pleasing. These are said to be consonant.

4. Scales. Over small spans of musical time (say 30 seconds or so), most musical styles tend to use just a few types of notes, between 5 to 8.

5. Centricity. Over moderate spans of musical time, one tonic note is heard as being more prominent than the others, appearing more frequently and serving as a goal of musical motion.

(Not to say that everything that sounds musical follows these rules, just that if you follow these rules the output is likely to sound musical.)

No argument here. I grew up programming from about the age of 8. I actually didn't program my computer directly -- I learned Roblox scripting first (Lua).

> Many children that age, if taught like an adult how sugar can harm them, will limit their intake of sugar. Giving them an assortment of other foods that are healthy makes it even easier for them to make the right choice. It's the same for TikTok.

TikTok was an example, for what it's worth. There are vast amounts of unhealthy time sinks that exist in the world, and they make money off of it. They have no reason to be respectful to children, and most of them aren't.

I don't know much about children, as I've never been a parent myself; all I know is that most of what exists today did not exist when I was a child, and most of what I used back when I was developing also does not exist anymore. That means I'm heavily biased, and I have no idea how you would keep a child in today's world off of those time sinks, because they were not a problem while I was growing up.

IOW the reason I can't recommend this is because I don't think it would have worked for me. It certainly doesn't work for everyone. And whether it's the "wrong choice" or not, it's a risk and one I would recommend against taking.

Even without controlling for profits (or lack of) and unstable leadership, it seemed obvious that many "tech giants" over-hired when they could get cheap money. When someone fresh out of school with no experience can get hired for $200k at a playground-like environment I interpret that as a red flag, not a new normal. Maybe because I have been through these downturns and layoff waves before. The big-spending tech giants and startups of dubious value now have to appease their shareholders and investors, an inevitability that no one seemed too worried about as long as the low-interest cash firehose kept spewing.
