Filters are not magic. They have tradeoffs. If you make a filter with a really sharp cutoff you end up with a really large filter with a lot of loss. So then you have trouble receiving really weak signals, say, reflections from the ground. One way you might overcome this is to really ramp up the transmitted power but that can cause radar receiver problems and can cause interference with services in adjacent bands, say, 5G.

This sort of thing is why allocating TV frequencies is and was complicated. That is because someone might live right next door to a TV transmitter and they might be trying to watch a weak signal on an adjacent channel. You usually have to allocate some dead channels for the area to prevent receivers from being overloaded. So in that case would it be fair to say that receiver was using channels it had no right to when set to the weaker signal? After all, the transmitter was there before the receiver was...

Note that other countries have managed to deal with this routine and common issue with respect to the introduction of 4 GHz 5G. There is something weird going on in the USA...
A quick thank you for your reply. I really enjoyed reading it. I wish more people on HN would take the time to agree or disagree with intelligence rather than the cult-like or ideologically-driven chains of comments often seen surrounding certain topics.

I'm at work. I'll have to come back later to actually reply to your comment. The quality and content of your reply required that I tack a moment to at least acknowledge it. I like it. Thanks for taking the time to post it.
Interesting, I will look into that.
> I think the issue is more with your understanding then my explanation.

That's what I said, that it doesn't make sense to me... hopefully it does make some sense to you!

> This notion is wrong. It CAN change. It just has an extreme low probability of changing from equilibrium to some low entropy state.

You also said before that the macrostate "changes with time; even at equilibrium".

There is no point in discussing fluctuations if we can't agree on the notion of equilibrium and the corresponding macrostate defined by its (average) macroscopic properties.

It's fine that you have your very own notion of things. Unfortunately it makes the discussion difficult.

I'm sure there's some justification about why it's 50% increase in price, but if it's a necessary increase then even releasing just seems tone deaf given the state of the world right now.

I use them for specific results or original/controversial ideas, but I wouldn't bother for something fairly obvious like "robots can sometimes outperform people." It seems like including an SO link for a bog standard for-loop in your code.

TLDR: with higher speed designs, there is not much info in the hobbyist space, because the designs get more complicated in terms of pcb layout, signal integrity and so on, and a lot of the tools used for more advanced PCB design work are unfortunately closed source. That said it is possible to do successful high speed designs with some rules of thumb that 90% would work on the first board dev. And open source tools like KiCad are getting there in terms of feature parity with the closed source tools. Happy to talk, my contact info is in my profile.

I didn't fight in WW2 obviously, but I did fight in a war. For me, the reticence to describe every detail to people who weren't there boils down to this: I don't want my wife, my children, or my neighbors to be burdened with thinking of something so horrible. I want them to be happy and safe, that's why I went. No need to bring it to their doorstep if I don't have to.

I suspect many during and after WW2 felt this way.
GP isn’t necessarily assuming bad faith. Suggesting that women are any more or less likely to be offended by something is Considered Harmful because it enforces gender binaries and stereotypes.

Most people don’t have malicious intent. The biggest reason that the tech industry is so infamously misogynistic is because people don’t actually know much about the issues of gender, and don’t really know what is misogyny.

Let me make this a little clearer and more to the point: suggesting that a company of 80% women would appreciate a mild dick joke in the context of whether or not the joke is safe for work is enforcing a gender binary that both separates women from men (by suggesting that there’s different senses of humor between them) and erases non-binary people. If you can think about it this way I’m pretty sure you can see why it’s also misogynistic even if you’re being “positive” towards women, as well as problematic in general, without GP needing any malicious intent whatsoever. And it could be avoided just as easily by being educated and aware.

This isn’t some sort of “snowflake” shit, either. We just live in a society that perpetuates these harmful gender stereotypes even during water cooler chit-chat, and the only way to change it is to point it out.

Please also assume good faith.

Edit: I don’t like the tone that I wrote this comment in, and so I want to make myself clear that I’m not trying to attack anybody either. My point is really that comments can be harmful without being written with malicious intent, and pointing it out when possible is important if anybody wants to see that aspect of society change.
This is such a strange article.

I too, in general, avoid starting with "pre-packaged" experiences when traveling. My most memorable experiences were only possible because, like the author, I travel light and don't plan too far ahead and mostly avoid being spendy. There's a kind of looseness and spontaneity that is possible if one plans generally and keeps funds available to take advantage of opportunities that only crystalize once you get to where you are going.

But the high-handed tone in this article, denigrating the popular attractions countries are known of, feels entirely at odds with that philosophy.

> I stay away from the coolest neighborhoods in the world, which all end up being variations of the same thing.

If you have spent any time traveling, you know this is a silly thing to say. Even the most tourist-y places like Bali, though you see similarities, retain a national character. They are also generally very different from the rest of their host country - bubbles with their own rules and features. This is a feature! I have never regretted spending some time in heavily tourist'ed areas. Being catered to and seeing how culture shifts is interesting and fun. Taking a break from forging your own path and doing some pre-constructed-fun is nice. The reasons those areas are popular is because they are interesting and fun!

To me, a lot of this comes down to balancing the time you invest in figuring out how to spend your time and money v.s. the time you want to take "doing the thing." If you have a low budget, then just kind of scrap around (you don't have a choice so there's no need to pretend this is some crazy tip). If you have a higher budget you have options! You can jump right into a pre-planned experience for a little bit or you can scrap it a bit and see what turns out. Ultimately, for most of us, even if you travel on "the cheap" you are still actually planning around a budget of how long you can skip work.

I 1000% think that, if people have never taken just a carry on to a less touristy city in a foreign city, you should consider it. But the experience is a close cousin to the one you have when you are in tourist land and the two approaches support each other.

The ones all in a line are recently launched. They are launched ~50 at a time into a low orbit and use thrusters to raise themselves up over the course of a few weeks or months. During that process they are all lined up in a row which slowly lengthens over time. As they reach operational altitude they separate into groups and each group spaces itself evenly around one orbit for even coverage.

Well that's good news. Thanks for correcting me. I think the attempt still makes my point that people are doing drastic things because of the prevailing narrative on the subject.

I also don't mean to rag on the kids, I appreciate their passion. I just think it's misguided, and that if the wider array of potential solutions were better known then people could be more productive working on solving the problem. I think the fatalism about the topic is sad and unnecessary. I didn't mean the comment to be a cultural war "pick a side" post. The passion around the subject is justified, but I think it could be channeled more productively.

Many people use to agree with Malthus in the 1800s that the world was about to run out of food. Then the Haber-Bosch process was discovered, and problem solved. More mental energy should be put into finding a similar solution for climate change versus this century's equivalent of "the world needs less people because of food limitations".
> What's the overhead of using FUSE to implement LiteFS?

It's a tricky question to answer. Most of the noticeable overhead is on the write side. Initial benchmarks of overhead that I've seen locally are about 250µs for the write(2) and fsync(2) calls. It's closer to 100µs for read(2) calls. There are additional writes made behind the scenes as well for storing in a replication format for the other nodes too.

However, on the read side some of that is moot. For many databases, most reads will be in the OS page cache and a fetch from there seems to be closer to 4µs. If you're running a moderately sized database (e.g 1GB) on even a modest VM (e.g. 256 RAM) then most of your hot pages will be in the OS page cache so you shouldn't notice much overhead on the read side.

LiteFS is targeted at read-heavy workloads. If you need high write throughput of thousands of writes per second then LiteFS probably isn't a good fit.

> Is there an issue with OS compatibility?

LiteFS is Linux right now. We'll be supporting other operating systems via a SQLite VFS extension in the future. macOS has poor FUSE support right now and I'm not sure where Windows and BSD stand with their support for FUSE or FUSE-like systems.
Exciting times. I wonder how scalable the materials tech is here.

In the past basically everything lost to Dennard scaling of silicon transistors. Then everything lost to massive capital spend to scale silicon transistors via other optimizations.

Now that we’ve clearly started hitting a wall (see Nvidia CEO recent statement on hardware no longer getting cheaper each cycle), these alternative paths may actually be able to compete on their own exponential learning curve.

That would further hurt silicon transistor scaling as manufacturers like TSCM shifted resources toward new materials scaling, creating a strong positive feedback loop.

As long as there’s some amount of scaling learning curve in a new material, it seems like the markets will shift rapidly (best guess 5-10 years) whereas before nothing could catch the exponential learning of silicon transistors.
> Shaming Musk for not doing something he never agreed to do, to the detriment of his company, is itself manipulative and parasitic logic.

This is a straw man argument, as that was not my argument, and I was not shaming Musk. I was merely speculating:

>> Maybe Musk is applying variation on a theme, maybe he's just honest to goodness unreliable and irresponsible for getting involved. Maybe Musk isn't a narcissist. Maybe he's also a sociopath...

"Maybe" is salient here, meaning "there is the mere possibility that..."

> All the same, fuck Amazon for offering a limited-use free tier. After a few months of free EC2, we apparently have a common-law obligation under which they have to keep giving me free service forever?

Yet more straw man argument. How does Amazon enter into this?

Now your straw man has taken over. You introduced and claim this is charity, but I was describing something else entirely.

> You're redefining the terms of an informal arrangement in a way that most benefits you at someone else's expense-- literally Narcissistic behavior.

Still more straw man fallacy punctuated by ad hominem attack. If you can't comprehend and speak to my words, but only attack me, then your argument is fallacious and not worthy of being entertained other than to call it what it is, straw man arguments and personal insults.

I think I am. If you see what's happening in Iran right now, it's clear that people don't always coldly calculate their chances to win and there is a threshold beyond which common decency and ambient morality will boil over to rage that overwhelms the instinct of self-preservation.

Or, even worse, to a nightmare existence were we are worse than beasts in a world destroyed and incapable of sustaining life.

1) For this very reason, it doesn't make sense to optimize low-level components from the OS down to the hardware anymore, and hasn't for over a decade, if an improved user experience is your goal.

The short-term effect may be a slight improvement, but it's a treadmill and the next wave of web crapware will more than nullify it.

If a microkernel architecture with worse performance got established on all mainstream devices, the experience would be worse in the short term but in the medium term, the crapware would have to adapt so that it again becomes just barely usable as it is today.

The problem is that the short-term gains create an incentive for users to buy/use the marginally faster hardware or kernel, which then forces everyone else to follow suit.

The on-die ECC serves only to make DDR5 as reliable as DDR4, despite the smaller cells and higher speeds.

Real ECC must be end-to-end, from the memory controller inside the CPU to the memory chips and back to the memory controller.

This allows the CPU to be aware of any errors, which is essential e.g. for detecting the memory modules that will soon fail, so they must be replaced, like in this story, and like it also happened in my computers.

Moreover, not only the errors that happen in the memory cells are detected, but also the errors caused by electrical noise on the PCB traces or those caused by poor contacts in the DIMM sockets.
