Show HN: Quanta – A Fast, Memory-Efficient Data Engine for Analytics
I've built Quanta, a Java-based data engine for fast, memory-efficient analytics on large datasets, all within a single JVM. It uses direct memory management, optimized indexing, and avoids the complexity of distributed systems. Early results are promising, and I'd love to get your feedback.

Key features:

* Millisecond-level queries

* Low memory footprint (~25MB/column for 20M rows)

* Fast ingestion

* Persistence and crash recovery

Example: Querying taxi trip data:

Java

// Query: Find taxi trips that originated in Manhattan, with Uknown payment
// and were picked up between 6AM and 11AM (pickup_hour > 5 and < 12).
Query q = taxiData.newQuery()
.and("pickup_location", "Manhattan")
.and("payment_type", "Unknown", "No Charge")
.gt("pickup_hour", 5) // pickup hour > 5 (i.e. after 5 AM)
.lt("pickup_hour", 12) // pickup hour < 12 (i.e. before noon)

Quanta is designed for speed and real-time analytics on structured, columnar data. Ideal for developers needing low-latency lookups without distributed system overhead.

Looking for your feedback!

It formed from smaller utilities ~1950. We have harsh winters and some small thunderstorms, but that's about it for weather.

Looks like people end up paying close to $0.30 per kwh. There's probably some cross subsidies coming from the state, I don't know.
Graphics drivers on Windows definitely do plenty of 'optimizations' for specific game executables, from replacing entire shaders to 'massaging/fixing' 3D-API calls.

And AFAIK Proton does things like this too, but for different reasons (fixing games that don't adhere to the D3D API documentation and/or obviously ignored D3D validation layer messages).
50 at least is not "wildly" off. Somebody could retire at 50, at it would be strange to have money run out by 100 - what if the person would live longer?

We can have something earned from the money, but pension money have to be conservative, so the upside could be limited.

$11k a month for "food travel and other things" - healthy food isn't unfortunately cheap, neither is good travel - but those other things could be even more expensive. You might want to start an enterprise, and you'll need seed money. You might support a cause, or run a non-profit, or do other things which are noble but not easily rewarding in monetary sense.

Yes, we as a society probably can't - not don't need, but can't currently - support this. But it doesn't mean people shouldn't aim for this.

Frankly, I don't see strong evidence against so far.
I don't think I needed squares for any of my notes. Graphes that I drew were just approximate. The squares are great for indentations, lists, tables, etc. My notes always looked sharper on engineering paper than regular ruled paper.
As always, "it depends." How simple are your pipelines? Single CSV? Sensible column names that are totally unambiguous? Consistent, clean data? Then LLMs are probably fine...
This is a well known phenomenon in traffic engineering and can be modeled with e.g. fluid dynamics.

Two questions for the author,

You say bitcoin can’t be debased. How is that true? Aren’t there a few big holders of btc?

If they decide to exit all at once wouldn’t the value crash?

And in the last paragraph you mention “the core value proposition of bitcoin”

What do you believe that is?
You have a source for these rumors, I'm sure?
I dunno, look at Elon with his X children.
Well, it's true that money/power generally corrupts people, but the vast majority of nerds are sociopaths (a fact, as far as I'm concerned) to start with, which normally does not manifest in their daily lives because they are heads down involved in their technical craft 24/7, it comes to the fore (predatory trait or otherwise) when they assume top positions in the hierarchy.

Then I think there is also the relatively rare situation of assumed, sociopathy when one realizes that the vast majority of their subordinates (or in general people) are a pretty sorry lot, if one where to peel back the veneer of civility and virtue signaling. I suspect that at least some successful technical founders of large companies fall into the category.
It is if they are dismantling the pieces for their own benefit. Removing power from the institution and giving it to themselves.

We built WorkHub.so to solve a problem every remote worker knows too well: finding the perfect coffee shop or workspace. After years of trying to make Yelp and Google Maps work for this, we realized they weren’t designed with remote workers in mind. So, we created WorkHub.so—a community-driven platform to help you discover and share the best spots to work or study.

Here's how we built this and host it from a M1 Mac Mini

Hey HN!

I just launched Robotlist – a platform where you can discover and compare AI robots, whether they’re virtual assistants, automation agents, or physical robots.

Right now, I’m collecting feedback from the community to improve the platform. If you’re building or know of an AI-powered robot, you can add it to the catalog and help expand the list! It's free.

Would love to hear your thoughts – what features would you like to see? What’s missing? Let’s make this the go-to place for AI robots together!

Looking forward to your feedback!

I think this is very accurate. The exception is probably those block buster games. Those probably get direct consultancy from NVIDIA during the development to make them NVIDIA-ready from day 1.
Ignore grumpy Sunday morning HNers. Cool work!
Your comment's interpretation is ambiguous. I interpreted as there are/were 10 people that had these special Blackberry phones, when the article says Obama's Blackberry was just limited to contacting 10 people.
It doesn't seem plausible to me that "why did you apply" is like an idiomatic expression. Where would it come up outside of a job interview? Are you saying that a non-autist would not get it in the first couple interviews as a young person then pick it up?
> and shows a harbour at Georgetown.

Look closer at that harbour. Especially its scale, and facilities. There's nothing resembling a spot to tie up (say) a 500' freighter. Nor a breakwater - if a storm hit the west side of the island, then everything afloat would have to be hauled out of the water, or flee.

(Yes, obviously my original comment should have been more specific.)

For military facilities, on a military budget, there's all sorts of "wait 'till the weather and tides are right, then transfer cargo ashore via helicopters and small boats" stuff that you can do. At commercial scale, the extra costs are poison.

Because that is a key improvement.
A slew of people including Musk, Vance, Curtis Yarvin, Peter Thiel, Marc Andreessen and a few other VC billionares are trying to break up the US into nation states that they call network-states. Think of Cyberpunk with a heavy dose of Snow Crash. It's a completely authoritarian agenda. While I understand this sounds like conspiracy, Andreessen quite literally has a book called "The Network State" and Yarvin has blogged about this extensively.

Different underlying causes for the same condition is possible.

Given how little we know about the internals of brain function, it’s not surprising to see conflicting indicators of the same condition.

I’m just a layman, tho, so what do I know.
I have been around a lot of academics and been in academia.

While we shouldn't trust academics just because they are academics, these people specialize in relevant fields and also back their claims with citations throughout the course. They are not just postulating.
A "branch" here is a conditional jump. This has the issues the article mentions, which branchless programming avoids:

Again, there is no branching - the instruction pointer isn't manipulated, there's no branch prediction involved, no instruction cache to invalidate, no nothing.

This has nothing to do with whether the behaviour of some instruction depends on its arguments. Looking at the Microsoft compiler output from the article, the iadd (signed add) instruction will get different results depending on its arguments, and the movc (conditional move) will store different values depending on its arguments, but after each the instruction pointer will just move onto the next instruction, so there are no branches.
I’m very far from an evangelist of the tech but I was under the impression they had gotten better at this sort of thing.

I question why a model which “knows” about cheddar / mozzarella cheese would make this blunder.

Was this supposed to be generated by one of those “show your work” reasoning models or is this just the regurgitation of one of the single short response parrot of old quora answer or reddit post ai chatbots?
no, not so simple.. the simplicity of this idea is like a gravitational pull for your human mental model mind. Meanwhile, LLMs are like a non-reproducible cotton-candy machine. Quality will be an elusive light at the end of the tunnel, not a result, for non-trivial systems IMHO. Simple systems? sure, but economics will assign low-skill humans to the task, and other problems emerge.

What is the intoxication that assumes the engineering disciplines are now suddenly auto-automatable ?
I agree, I think that barbering and haircutting shouldn’t take nearly what it does.

I was just pointing out that the pilots license hours comparison is not great. 1000 hours of classroom instruction at a cosmetics school is 6 months full time. 1000 hours in a cockpit takes years.
I was thinking how this article claims that people crave the authenticity of live music and that bullshit-generators will never be able to supply that. At first, I saw this as a reason for optimism, but then I got to thinking about evidence that people may not necessarily want authenticity after all.

Organic produce was the first metaphor the came to mind: it's probably more healthy for you even if it isn't as pretty, but many people aren't willing to pay a premium it and I suspect economics isn't often the reason. Is that a straw-man for live music? I don't know that it is because plenty of people are content to listen to recorded music -- sure, they might enjoy going to a live concert but they'll still listen to the radio on the drive to work.

Then I got to thinking about something more crass: while breast implants and other cosmetic body surgery may be as much for the benefit of the subject self-image I imagine there are plenty of people that find it very attractive despite what is often obviously fake.

So do we crave authenticity? I think I do but I'm not sure if that's a safe generalization to make.

It makes sense to have an embodied AI, i.e. a robot. Self driving cars count.

But it doesn't have to be modeled after humans. The purpose of humans if we can call it that is to make more of itself, like all forms of life. That's not what we build robots for. We don't even give robots the physical abilities to do that. Giving them a human mind (assuming we could) would not be adequate. Wrong body, wrong purpose.
This should be quantified and generalized for a full set of cases - that way the argument would stand far more clearly.
> A slew of people including Musk, Vance, Curtis Yarvin, Peter Thiel, Marc Andreessen and a few other VC billionares are trying to break up the US into nation states that they call network-states.

Network states? Like, turning CNN, FOX and MSNBC into actual governments? That might not be such a bad idea after all, given the extent to which society gets divided along ideological lines these days. It might work along the lines of explicit "pillarisation" in the Netherlands.
Eventually our understanding of the term will evolve to match its use, which is my point with the Doctor anecdote. Don’t try to fight the evolution of language; you may as well stand with Canute by the sea, yelling at the tide. No more did Victorian prescriptivists end the splitting of the infinitive.
Show HN: Oxidase – Transpiles TypeScript at the Speed of Parsing
Hi HN,

Oxidase is my experiment to build a TypeScript transpiler that works like ts-blank-space[0] and Node.js' built-in type stripping[1], but also supports enums and namespaces.

I've tried some optimizations on it and am surprised to find that it's now as fast as oxc, the TypeScript parser it's based on. Check the link for the benchmark results and details on how I make this possible if you are interested.

The name pays homage to oxc (same prefix) and sucrase[2] (name for another type of enzyme), where I borrowed the idea of no AST allocation optimization.

Thoughts you kicked off...

I imagine myself driving across the country, and arriving at a small town to get gas and lunch. As I eat at the local diner, I become aware that everyone in the town is dressed exceptionally well, better than I am in fact, including the two homeless people outside, sitting in the street.

Turns out this small down of 400 people has such a tailor, and no Walmart, and so even the poorest are dressed quite well, with perfectly fitted suites and clothes.

One of the claim made here is that we are wasting time putting our money to work.
I would argue the contrary. In a world where people are just putting their savings under their mattress, it's a shame.

Money is energy. Instead of let it aside "in case we need it later", it should help other people to grow, and give them an extra pair of hands.

If we don't want to waste time looking at where to invest it, then taxes to put dormant money into a sovereign fund, which in return will give out the interest in the form of social measures, is something that can be done as well.

No, turning Tesla, Meta, and etc into actual governments.

For your wimsey library, using “pipe” to validate the contracts would seem to me to drastically slow down the Polars query because the UDF pushes the query out of Rust into Python. I think a cool direction would be to have a “compiler” which takes in a contract and spits out native queries for a variety of dataframe libraries (pandas/polars/pyspark). It becomes harder to define how to error with a test contract but that can be the secret sauce.

I don't work on the nvidia side of things but it's likely to be the same. Shader replacement is only one of a whole host of things we can do to make games run faster. It's actually kind of rare for use to do them since it boats the size of the driver so much. A lot of our options do change how shaders work though, like forcing a shader to use double precision floats instead of the single it was compiled with.

Compared to the cost of building a DC, using 24K gold for all the wiring in it would be small change.

It's fine in imagination or fiction. But in the real world, the guys who sign the checks seldom buy that type of "cheap compared to" argument.
Branching is different instruction paths, so it requires reading the instructions from different memory that causes a delay jumping to those new instructions rather than plowing ahead on the current stream of instructions. So a conditional jump is a branch but a conditional move is just an instruction that moves one of two values into a register but doesn’t affect what code is executed next.
Optimal temperature for yeast in general is between 25-30C, for grape wine optimal fermentation is usually between 15-20C (white) 20-25C (red).

So 35C is interesting. 350 would be too much even if it was Kelvin.
For those curious about this position / organization:

> The National Archives and Records Administration (NARA) is an independent agency of the United States government within the executive branch,[6] charged with the preservation and documentation of government and historical records. It is also tasked with increasing public access to those documents that make up the National Archives.[7] NARA is officially responsible for maintaining and publishing the legally authentic and authoritative copies of acts of Congress, presidential directives, and federal regulations. NARA also transmits votes of the Electoral College to Congress.[8] It also examines Electoral College and constitutional amendment ratification documents for prima facie legal sufficiency and an authenticating signature.[9]

* https://en.wikipedia.org/wiki/National_Archives_and_Records_...

* https://en.wikipedia.org/wiki/Archivist_of_the_United_States

Some of Trump's past experience with NARA:

> Under the first Trump Administration, the National Archives had significant difficulty maintaining historical records as the President would often rip, flush, and otherwise discard records,[25][26][27] which would then have to be reconstructed and reclaimed by White House and NARA archivists. Additionally, according to multiple former staff, the President would ask to keep certain records that otherwise would be returned.[28][29]

> As part of its role in receiving and authenticating Electoral College votes, the agency intercepted and rejected forged certificates of ascertainment from Trump allies in seven states who were strategizing to overturn the 2020 presidential election.[30][31]

> Upon leaving office in 2021, Donald Trump delayed providing material to the National Archives in accordance with the Presidential Records Act. In February 2022, U.S. Attorney General Merrick Garland announced that the National Archives had notified the Justice Department that it found classified documents within boxes provided to them from the former-president Donald Trump's residence at Mar-a-Lago.[32] After further investigation, the Federal Bureau of Investigation executed a warrant for a search of the residence in August 2022.[33][34]
