Because one does not just profile their code. It branches, different parts do different things. You need to run the code with sensible input, multiple different inputs to hit the different branches etc.

If you have a good workflow that includes profiling your code that's cool, it's probably a good way to improve the performance of your code. But personally I think it's enough to test the code and make sure it works and is reasonably fast. I'm not going to spend time eliminating nano and low digit milliseconds.

If something actually keeps users waiting I'll look into it. As long as it's near instant it's good enough for me.

Apologies, almost missed this response.

Agreed that there are other ways, almost certainly. I was going with the assumption that we wanted to store positional values for that question.

That is, it is only when you assume that you have to write out all decimal digits that you get people writing silly things that computers do all of the time. "0.66666...7" is an easy example. Ironically, to me, is that in written assignments you likely would have gotten knocked off points for not writing 0.(6) where () means an overbar. You definitely would lose points for rounding at the end.

Try a "Show HN" for starters. Whatever you do don't post an Ask HN with a link in it because that's a classic rookie mistake -- links don't work in an Ask HN post!

If you say "people won't understand my product if they just visit the landing page" you're doing it wrong! The expectation is that people will visit your landing page with zero context so your landing page must say enough about your product that it stands on its own. If you really want to explain a bit it is OK to post a comment on your own "Show HN"

> For all we know, the middle is just air and crumpled-up old newspaper.

I think this is the answer. I suspect the exhibit designers had a cool idea for a display, did a rough estimate of the area needed and then commissioned the exhibit builders to make the big metal-framed cube. Either they made an error in their calculation or the innate variability in the size of stacks of used bills threw it off. It's also possible the exhibit designer simply decided a bigger cube which filled the floor to ceiling space would be a better visual. Which would be unfortunate because, personally, the exhibit concept I'm more interested in is "$1M dollars in $100 bills fits in this area" not "Here's $1M in bills." The first concept is mildly interesting while the second is just a stunt.

Regardless of the reason it's off, I think it's most likely there's only $1M of bills in the cube. The folks responsible for collecting and destroying used bills tend to be exacting in their auditing for obvious reasons. So when the exhibit designers got $1M in used bills approved and released, that's exactly how much they got. It also stands to reason that they'd design the cube a little bigger than their calculated area requirement to ensure at least $1M would fit (along with some method of padding the interior) - although >50% seems excessive for a variability margin, so I still think it was an aesthetic choice or calculation error. Of course, one could do a practical replication to verify the area required with $10,000 in $1 bills.

Regardless, it's an interesting observation and a cool counting program to help verify.

A lot of this seems uninformed projection of your own fears. Your toddler quite literally has more rights to exist in a space not your home than a dog. Unless you mean to say that as long as dogs exist in a public space, your child’s existence is threatened.

Untrained pitbulls can be dangerous, but did the dog display any aggression at any point? Or is the whole story just “a well trained dog was in the vicinity of children, presumably not off leash, and I did not like that because I fear for my children all the time”? And are you actually allergic to dog fur or are you more concerned about the fictional person who may be allergic to dog fur, but only to the fur from larger dogs? Because the reality of dog allergies is that they are not really caused by the fur itself, regardless of the size.

Btw this is what I meant when I pointed that most discussions are emotional than rooted in reality.

Taxes work on "self assessment" basis meaning you, the taxpayer have the burden to declare all facts relevant to assessment of your tax and you pay the tax.

Then, sometimes your case is picked for audit and then they check if what you declared is correct as per applicable laws or not.

See, here is a small mom and pop shop... who owns that? Is the premises on rent? How much ? Is the rent deed valid and proper? Maybe you are paying less rent than declaring? Are you actually employing people you say you are? Are you paying them exactly you say you are paying?

How would you ensure that fact db is not having funny data ?

Say i am saying i am paying 100 bucks a week for fuel but fact is, my shop is next door to my home and i am just pocketing this cash daily. If i keep putting this 100 bucks weekly expense in this factdb, how will govt know.that i am not lying?

Seeing latency figures measured in hundreds of milliseconds in the best cases really drives home for me how big of a deal solutions like SQLite can be.

If you took their exact same hardware and put the application+SQLite on the same box, you could literally chop 4 zeroes off these p99 latency figures. NVMe storage is unbelievably fast when it's utilized in the same machine that the application runs on.

For 640x480 output not overclocked, I estimate tile + sprite CPU utilization to be about 50% of one core. Of course you have two cores. That number goes up and down depending on resolution, particularly when you're pixel doubling.

It's absolutely doable. There's the beginning of a tile demo (a scrolling brick wall) in the pico-dvi-rs repo.

Hi! I'm on the engineering team at SI and I recorded a live demo of using its new UI on the Steam Deck. System Initiative is what we believe to be the future of infrastructure automation and management.

The new UI is a work in progress and this is a raw, unrehearsed demo showcasing how it runs on a Steam Deck (barring a few retakes and cuts). I came up with the idea awhile ago and I thought this would be a fun way to share where we're headed with SI.

Microtransactions are the perfect solution, if you have an economic theory that assumes near-zero transaction costs. Technology can achieve low technical costs, but the problem is the human cost of a transaction. The mental overhead of deciding whether I want to make a purchase to consume every piece of content, and whether I got ripped off, adds up, and makes microtransactions exhausting.

When someone on the internet tries to sell you something for a dollar, how often do you really take them up on it? How many microtransactions have you actually made? To problem with microtransactions is they discourage people from consuming your content. Which is silly, because the marginal cost of serving one reader or viewer is nearly zero.

The solution is bundling. I make a decision to pay once, then don’t pay any marginal costs on each bit of content. Revenue goes to creators proportionally based on what fraction of each user’s consumption went to them.

People feel hesitation toward paying for the bundle, but they only have to get over the hump once, not repeatedly for every single view.

Advertising-supported content is one kind of bundle, but in my opinion, it’s just as exhausting. The best version of bundling I’ve experienced are services like Spotify and YouTube Premium, where I pay a reasonable fixed monthly fee and in return get to consume many hours of entertainment. The main problems with those services are the middlemen who take half the money.

> ORMs attempt to deal with that mismatch.

Technically ORMs attempt to deal with the mismatch between relations[1] and the rich data structures (objects) general purpose programming languages normally allow expression of. Hence the literal name: Object-Relation Mapping. That SQL, the language, is declarative is immaterial.

> but Codd's goals when developing the relational model was to allow non programmers to access data.

That is unlikely. He was staunchly opposed to database vendors adding "veneer" to make use more friendly and considered SQL an abomination. Codd was dead set on mathematical purity, which is, I'd argue, also why his vision ultimately failed in practice as actual relational databases are too hard to understand for those not well versed in the math.

[1] Technically tables, since we're talking about SQL, which isn't relational. But the mapping idea is the same either way.

I see most people stating that the internet as we know it could be gone because of AI.

I’m asking you: Why not? The internet is not even a typical human lifespan old. It’s crazy young on a large scale. Why would anyone assume that it will (and has to) stay the way it is today?

There are so many downsides of the current web. Slob everywhere (even long before AI) because of all sorts of people trying to exploit it for money.

I welcome a change. An internet with less ads, more genuine information. If AI will lead to this next phase of the internet, so be it. And this phase won’t be the last either.

"The Engine of Levitation – Open to the World, Guided by Claudia Teotonio"

Today, I, Claudia Teotonio, am officially releasing the Engine of Levitation as an open-source technology for researchers, engineers, and innovators worldwide.

The Engine of Levitation represents a breakthrough in propulsion, aiming to achieve inertial propulsion through an innovative system of Inner-Thrusters, Outer-Thrusters, and Thrustees.

Why Open Source?

I believe scientific progress should be collaborative, not limited to a few institutions. By making this technology open-source, I invite the world to study, test, and refine the system—while ensuring that its development stays ethical and transparent.

Terms of Open Use

Anyone can use and improve upon the design, but must credit me (Claudia Teotonio) as the original inventor.

Non-commercial projects can freely build and experiment with the engine.

Companies or governments wishing to commercialize or profit from this technology must obtain a licensing agreement.

What’s Next?

A glider prototype is currently under development to validate the engine’s capabilities.

I invite universities, aerospace companies, and independent engineers to collaborate on further testing and refinement.

A dedicated community forum/research group will be created to track progress.

How to Get Involved

Access the technical documents and blueprints at the like provided in this page.

If you're interested in collaborating or licensing, contact me directly at blakangel@hotmail.co.uk / marcio7kr@gmail.com

Let’s shape the future of propulsion together while ensuring ethical, transparent, and open innovation.

Engine of Levitation | Public Announcement Claudia Teotonio Announces the First Verified Inertial Propulsion Engine After over a century of theory and speculation, the world now enters the era of inertial propulsion. Inventor Claudia Teotonio proudly announces the successful creation of the Engine of Levitation, the world's first functioning inertial propulsion system capable of generating net directional thrust in a vacuum, without ejecting fuel or propellant. "The dream of reactionless propulsion has become reality," said Claudia. "The Engine of Levitation proves that we can move through space by manipulating internal momentum, timing, and magnetic force." What It Is The Engine of Levitation is a patented inertial drive that uses: - A rotating Outer-Thruster - Reciprocating mass drivers called Thrustees - A fixed Inner-Thruster core - A magnetic gyroscopic system called the Maggyro These parts work together to create pulsed, non-canceling internal forces that produce sustained thrust. Why This Matters - Enables spacecraft propulsion without fuel - Improves drone and satellite maneuvering - Offers quiet, efficient movement for submarines - Removes the limitations of mass-based thrust "This is the end of the rocket era," Claudia said. "And the beginning of motion mastery." The Proof Lab tests using a frictionless platform and sensors showed measurable net displacement consistent with theoretical impulse models.

Did you account for the paper band that wraps the 100 one-dollar bills? Not nitpicking, but you said you counted everything you could see.

It should be between 0.002-0.004 in. thick, so each band per bundle is about 0.004 to 0.008 thick. Might take off a little bit of your overage.

Tigers and such feel like a good counter example to colors needing eyes to see them? Specifically, the color of tigers is largely evolved against eyes that don't see the orange.

As such, many colors would be expected in environments that don't confer an advantage to colors. And once an environment starts to give advantage, you would expect rapid convergence.

Which, maybe I'm just reinforcing old learning of mine? Moths were a specific way of teaching evolution in my grade school, and they acted exactly as I just described. With soot covered areas growing rise to black colorings and cleaner air giving rise to the opposite.
