Yeah, I’m sure there are folks for whom Indiehost will provide a value add on top of what Coolify Cloud offers, and I think tabulating them and demonstrating your value proposition is easy enough, (support, ease of setup, cost savings over the mid-to-long term, etc.), and I like that you refer to the self hosting option in the FAQs, just would be nice to see the two services side by side!

Ask HN: How to choose the correct Q value for the EQ peak filter?
I developed a music player https://github.com/ZTFtrue/MonsterMusic. But there has a question for me.

I am a novice at developing music equalizers.

I am using a BiQuad Peak Filter from this site: BiQuadDesigner
However, I encounter noise when I set some band gains to 13 dB and Q to 1 (I've tested other values as well).

I have noticed that some software can use these values without producing noise, such as Webamp.

I have read other articles to learn how to set Q, but they haven't helped.

Currently, I am using normalization to avoid noise.

```
sampleBufferRealLeft.forEachIndexed { index, it ->
var outY: Double = it
mCoefficientLeftBiQuad.forEach { filter ->
outY = filter.filter(outY)
}
leftMax = FastMath.max(leftMax, FastMath.abs(outY))
sampleBufferRealLeft[index] = outY
}
if (leftMax > 1.0) {
sampleBufferRealLeft.forEachIndexed { index, it ->
sampleBufferRealLeft[index] = it / leftMax
}
}
```

`leftMax` is the maximum value of all frames processed, which helps avoid noise in a song.
I think this is right, it's a gamble. Discoveries and advancements are made by people tinkering with things without the mind to commercialise it.
Is there some end to this criticism or do you have some stake in dismissing big endian architectures?
To clarify: My point is not that Firefox sucks, my point is that Firefox is great - better at handling the web than these new other web-browser engines will be for a long time, and yet it still hasn't broken the moat. It's not enough to make a great non-chrome web-browser - we already have one. It wouldn't make any difference toward that goal if we had 4 of them.

What is needed to break the moat are users - and enough for website operators to care. This is what Apple/Safari has. This is what Firefox increasingly lacks.

For and for that someone will have to do something other than make a great browser.
The article says "Making a mistake is not a fraud. If Tesla really thought that it could deliver unsupervised self-driving to vehicles equipped with HW3 and, at one point, it figured out that it couldn’t, it’s not fraud even though it used that as a selling point for millions of vehicles for years."

Does that mean I can claim I made a mistake if I do something wrong and get caught?
Nominally, corporate R&D should in fact have a good chance of making it into a real product if the technology works. It should not be a certainty that the technology will work.

Intel's R&D produces a lot of technology that works but never makes it into a product.
Life in a less dense city itself would be different (fewer career opportunities - despite remote work, less cultural opportunities, etc). Also kids become more independent earlier so we won't have to drive them everywhere as teens etc.
> MNCs also don't force you to pay taxes

So wrong. Every dollar that $FOO_COMPANY shovels to Google and Apple to spend on advertising is a dollar that you, the consumer, end up footing the bill for; a dollar that does not go towards improving the product you receive in any way whatsoever.

The advertising industry itself is a tax on the price of everything.

I'm not a lawyer either, but from my interpretation, they would be considered unprivileged combatants, and so would not get POW protections either.

https://en.wikipedia.org/wiki/Unlawful_combatant#Unprivilege...

That being said, it doesn't really look like that means you can use booby traps when you wouldn't otherwise be able to do so, even against unlawful/unprivileged combatants:

https://lieber.westpoint.edu/exploding-pagers-law/

> Where the exploding pagers are concerned, my provisional view is that we are dealing here with booby-traps. The munition is not being manually emplaced in the manner required by the “other device” definition. The pager is being adapted to convert it into a booby-trap of the sort addressed by Article 7(2) of Amended Protocol II and on that basis it would appear, considering what is currently known and assumed, to be an unlawful weapon.
Cranking up R&D especially during a time to perfect the trade sounds backward. Intel probably has 6 more years then to release anything into full production.

Exactly. I see elsewhere in this page people comparing this project to Linus Torvalds starting an OS in his dorm room while studying CS. Like these were "young and clueless" devs writing an OS for fun.

From the looks of it, this seems like a serious corporate backed project made by employees of the Ant Group, the chinese fintech giant. A more fair comparison would be with Google's Fuchsia OS (defunct) or Huawei's HarmonyOS. It may succeed, it may fail, but it's nothing like a couple of kids doing a passion project to learn Rust.
Low-e windows coatings have been around since the 70's. They have gotten better over the decades, but I can't say how much they've changed. When buying new windows, this is a very common and cheap option.
It is and it isn't a false dichotomy.

It is a false dichotomy in that in the Aristotelian sense of "X -> Y" means that absolutely, positively every X must with 100% probability lead to Y, it is absolutely true that "This is a quick fix -> This not the best fix" is false. Sometimes the quick fix is correct. A quick example: I'm doing some math of some sort and literally typed minus instead of plus. The quick fix to change minus to plus is reasonable.

(If you're wondering about testing, well, let's say I wrote unit tests to assert the wrong code. I've written plenty of unit tests that turn out to be asserting the wrong thing. So the quick fix may involve fixing those too.)

It is true in the sense that if you plot the quickness of the fix versus the correctness of the fix, you're not going to get a perfectly uniformly random two dimensional graph that would indicate they are uncorrelated. You'll get some sort of Pareto-optimal[1] front that will develop, becoming more pronounced as the problem and minimum size fix become larger (and they can get pretty large in programming). It'll be a bit loose, you'll get occasional outliers where you have otherwise fantastic code that just happened to have this tiny screw loose that caused a lot of problems everywhere and one quick fix can fix a lot of issues at once; I think a lot of us will see those once or twice a decade or so, but for the most part, there will develop a definite trend that once you eliminate all the fixes that are neither terribly fast nor terribly good for the long term, there will develop a fairly normal "looks like 1/x" curve of tradeoffs between speed and long-term value.

This is a very common pattern across many combinations of X and Y that don't literally, 100% oppose each other, but in the real world, with many complicated interrelated factors interacting with each other and many different distributions of effort and value interacting, do contradict each other... but only if you are actually on the Pareto frontier! For practical purposes in this case I think we usually are, at least relative to the local developers fixing the bug; nobody deliberately sets out to make a fix that is visibly obviously harder than it needs to be and less long-term valuable than it needs to be.

My favorite "false dichotomy" that arises is the supposed contradiction between security and usability. It's true they oppose each other... but only if your program is already roughly optimally usable and secure on the Pareto frontier and now you really can't improve one without diminishing the other. Most programs aren't actually there, and thus there are both usability and security improvements that can be made without affecting the other.

I'm posting this because this is one of those things that sounds really academic and abstruse and irrelevant, but if you learn to see it, becomes very practical and powerful for your own engineering.

Here is an idea: your thinking is to some degree based on heuristic predictions, which are a consequence of millions of years of biological and cultural evolution, and it is possible to notice when a human is engaging in such behavior.

More speculatively: I think there may be a way to get someone to transcend their cultural conditioning and admit when they slipped up in this manner, something that inevitably happens to all of us.

Stalking the Wild Banana
Anyone who aaccepts a claim that a vehicle will become an appreciating asset is an idiot.

It might appreciate, once, if Tesla ships FSD and creates a robotaxi market.

However, something in active production, providing a commodity value add, and competing with newer versions of itself is never going to continually appreciate.
I've used them in the past to keep interface and implementation separate. It's an easy way to stick an adapter between something concrete and the thing that needs something but doesn't care where it's coming from.

So, for example, I could have a IGadgetStore with methods for creating, retrieving, updating, and deleting gadget instances and then I can have a bunch of different classes implementing that interface. An obvious example is to have a PostgresGadgetStore and a MysqlGadgetstore and CsvFileGadgetStore. If the user wants to implement their own store that I haven't written, they can.
thanks! I didn't know about Robotwar and its fascinating, I just wanted to democratize this through normal english prompts, so anyone regardless of their coding ability can participate. Tbh this has been a dream of mine since childhood but I never had the ability to execute until the dawn of Cursor, Claude, and v0 :)
An approach that I've seen work reasonably well:

Spend a bit of time just talking to them. Work background, but also just finding out who they are as a person.

Give them some code to read - one page. It should compile - don't ask them to be a compiler. It shouldn't depend on obscure library calls, though it can use well-known ones. The question you're asking them is, what does it do?

Then, give them some code to write. Not a leetcode problem, but something one level above FizzBuzz. Yeah, this is probably at a whiteboard, but it could be at a keyboard in an IDE if they want. They can use any language they want. You want them to think out loud while they're doing it. Can they figure out the steps to implement a solution? Can they write code that isn't too badly broken? Again, you aren't asking them to be a compiler - if they miss a semicolon, that's not a failure.

Then, you ask them to do a bit of design. Just draw some boxes for how they would break up some problem. You're not looking for perfect UML here. Can they design a subsystem, or not?

Then, you ask them if they have any questions for you.

That's it. Two hours max. You might give them a half-hour phone screen before you schedule them for the interview.

That is a large part of it. Maybe that solving this problem leads us to the answer to other problems.

If you could prove the twin prime conjecture, that means you have figured out something about prime numbers. If you found a pattern or formula for figuring out the distances between twin primes, that means you're able to identify certain primes.

And maybe that formula becomes the basis for a formula for the distance between primes in general. And once you have that formula, you have a simple way to test for primes.

And I'm not saying that is happening or will happen or is even possible, but that would be a reason to study proofs of the twin prime conjecture.

It's a macOS app and I've found it great. However if given an ASCII diagram, you cannot edit it with the same ease as creating a new one (e.g. reflowing text or resizing boxes).

I really like the idea of having the mermaid source and the ASCII diagram together, so you could use the source to change the diagram if needed. But I feel that would feel cluttered to have both in a plain text file or comment, where ASCII diagrams shine.

It was more a figurative comment, I am not going to actually ask anyone anything.

But it is my sense from past conversations that none of these friends and acquaintances would be willing to trade back. I also think it’s reasonable to conclude that the people who stayed vs the people who left might have different opinions over those governments too.

The man who is willing to risk floating 90 miles across shark infested seas in a makeshift raft might have a different perspective of security and personal risk then someone who just kept their head down and suffered silently…or was content in their station.
This is really cool, glad to see someone making a real product out of this - have seen demos in the past.

One thing I've always wondered is if this could be made to work for group video chats - depending on the tile you are looking at, that person would know, so you could tell who is paying attention to you, or even exchange a furtive glance with a colleague in reaction to someone else said like IRL. Even harder, but also cool would be updating the gaze dynamically so you could tell what they were looking at in your scene - say you have a whiteboard behind you and you can tell when the person is making eye contact with you vs looking at something you drew on the board.

Original dev make it so! :)

They basically have two. Just like e.g. Amazon has both retail and cloud infra as separate, independent business models.

One is described well in the article, originally aimed at commercial clients. The article isn't short but we're on HN, not Reddit, so we should read the articles. Parts 2 and 3 describe it. The linked note at the end of 3 is very relevant.

The other one is the gov one, which is also mentioned as "Palantir has prevented terrorist attacks".

The article actually links to lots of product docs. It isn't secretive, plenty of videos on Youtube demoing the software. The docs are public, which is more open than can be said for 90% of software in their price range.

When I saw the title, I specifically thought it wasn’t going to be yet another AI image slop generator but something like https://minimator.app where you can create something interesting and fun by embracing constraints.

Alas, it’s just yet another write-prompt-get-image tool like the other bazillion out there. It’s not even (I’m sorry to say) well designed. Dark text on a dark background is unreadable.

Taking into consideration the submitter’s history, this looks like yet more AI spam.
> Not sure if you are trying to prove my point or not.

Yeah maybe we’re talking over each other. My point is that it all depends on what you build. A wrapper with an elaborate prompt does not too me sound like moat (I can be wrong). That’s where the bigger fish would not leave money on the table and eat them all.

That said, I suspect the company in question has much more moat than that. End user products make or break based on details in UX, even if they’re “doing the same thing” from 1000m away. And once the dust settles, the tech that’s integrated well into products win anyway, no matter the VC hype and valuations.
Well the PCB design isn't my strong side either - I am completely self-taught in that regard and I'm sure people who have studied that will tare me apart for any decisions I've made(also valid for all of my projects involving PCB's in the past, even more so considering I make the PCB's at home with a diode laser). Likewise, software is my domain.

Some others have mentioned a couple of key points such as zoning and parking requirements, but it's not just that. Other factors include a real estate development company's rate of return. If they buy a plot of land, let's say a quarter acre, they can fit let's say one $250,000 house on it, though likely that leaves them with too much space for the one house so let's say they go and build two $250,000 houses on it. Awesome right?

But if you're the real estate company that's a lot of overhead and duplication. Maybe you need to get twice the permits. You need twice the customers to buy. You have to bring your construction crews out to build two sets of crappy counter tops and kitchen cabinets.

How do you solve that problem? You build one $500,000 house (or more). You say the counters are "granite" and the floors are "hardwood". It's a forever home!

Now the two families that can afford the $250,000 houses each can't afford the $500,000 house of course or else they would be looking for a $500,000 house. So now they're out and the builder can sell the $500,000 house and make extra money.

There's nothing wrong with this, but it clashes with a problem that we face as a society which is not enough housing at prices that the public deems affordable.

The market can theoretically solve this, but sometimes markets get caught in local minimums that are misaligned with what the public wants. This could be an area where the government can step in and provide contracts to smaller builders, or just contract to build larger housing units (think of the now very expensive housing in NYC) and sell them at little to no gain or just give them away on a lottery system.

The money that would be needed to be spent is rather minuscule in comparison to the money we spend on other things. I'm unsure why we don't pursue a policy where we allocate, say, $100 billion toward building smaller and mixed-use housing. We have plenty of money to do so and it's really great for the whole country economically - I don't think anyone loses out. Congress needs to act.
I don’t know if that clarified.
ClipBoost – Clean and Repost Viral Videos with Fresh Metadata
Hi everyone,

I'm excited to share ClipBoost, a tool I’ve been working on to help content creators, marketers, and businesses refresh old viral videos by cleaning their metadata. Our goal is to give new life to old content by making it "appear" new to social platforms.

What ClipBoost does:

- Removes metadata from videos, including things like ICC profiles and MD5 hashes.
- Reformats color space for compatibility across platforms.
- Enables you to repost old viral content with a fresh start, without being penalized by social algorithms.
- Copyright-safe video processing to avoid detection as duplicate content.

Why I built this: I’ve spent a lot of time creating and editing videos, but sometimes, even great clips don’t perform well. Instead of wasting them, ClipBoost allows you to give these videos another chance at going viral.

Tech Stack:

Hosted on Render with MongoDB for database management.
Built using JavaScript, Vue.js for the frontend, and Stripe for payments.

Available at clipboost.io

I’d love feedback from the community, especially on how we could improve the tool for video creators and businesses. Happy to answer any questions!
You did an excellent job with the website design. It's simple, sleek, and easy to navigate. I have a few suggestions for further improvement:

- Add Google Sign-In: This can streamline the authentication process, making it faster for users to sign up and log in, potentially increasing your user base.
- How It Works Section: The section looks great, but the background photos have high opacity, which makes it harder to appreciate the website's design and content. Reducing the opacity could enhance visibility.

I also have a question:
Can users upload a book (like a PDF) and read it together with friends?

Additionally, do you have a library section where people can access free books?

One more suggestion:
- You could create a widget that bloggers, influencers, and others can link to their Goodreads account (or manually add a list of books they've read). They can embed this widget on their website to showcase the number of books they’ve read or are currently reading. Goodreads offers a similar feature, but it's not very well designed, so improving the aesthetic appeal of your widget could be a great advantage.
