As a counterpoint, doing a rewrite of an example of the best C codebases gives you a much more interesting comparison between the languages. Rewriting a crappy C codebase in a modern, memory safe language is virtually guaranteed to result in something better. If a carefully executed rewrite of SQLite in Rust doesn't produce improvements (or some difficult tradeoffs), that's very informative about the relative virtues of C and Rust.
Yes, and I don't think this is racism any more than other DEI/education initiatives that focus on one demographic more vs. another. Everyone talks about trying to get more blacks into gifted programs or selective high schools like Stuyvesant. This is scoping the problem, nothing more.
The key difference is that the problem being solved is a math problem. It can be written down on paper.

A ball falling on the ground can be converted into a math problem. To get the conversion exactly right you will need to write down the exact state of the ball. But you will invariably incur small inaccuracies while doing this. For example, maybe the mass you write down is off by 1 part in a trillion. The math problem is the ground truth, so any conversion inaccuracies are now errors in the ball. In practice these inaccuracies will prevent even the original ball from solving the written down problem much better than you could with a computer.

In the case of random circuit sampling, the written down problem is a tensor network [1] (that happens to also be a shallow quantum circuit). Fundamentally, a tensor network just specifies a bunch of matrix multiplications to do. It's not even that big of a problem: only a few kilobytes of information (whereas the exact state of a ball would be gargantuan). All you have to do is perform the specified multiplications, interpret the result as a probability distribution, and sample from it. The obstacle is that these multiplications create intermediate values that are really really large. The quantum computer bypasses this obstacle by executing the tensor network as a circuit.

Yes, I agree. Multidimensional effects for all tech applications. I should have thought more deeply there.
How much biology do you know?

The sugar in soda is already pretty simple, so what would gut flora actually do to it? What possible byproducts could there be from microbes processing fructose? If the sugars were entirely processed by the gut flora then that would generate a ton of heat and gas in the gut that would be uncomfortable at best or most likely just kill you.

Does gut flora influence how nutrients get absorbed? Almost certainly. Is there a behavioral and/or metabolic component to weight loss? Again, almost certainly.

But if you measure how many calories you were eating at maintenance and then eat 500 less per day, you will 100% lose weight. Will you lose a pound a week, the amount predicted by the simple caloric model of weight? You might lose a little less, but you will lose weight for sure.
That doesn't mean much until it's got feature parity.
> US has excellent education by the standard, commonly used international measures. In PISA, for example, white American children score better than any European country, and are only outscored by a handful of East Asian countries. These are all in turn outscored by US Asians, putting US on top yet again. US has a bunch of lower-performing population groups, who bring the overall average down, but even these perform better than their foreign counterparts. US blacks perform better than blacks in any African country, immigrants from South America perform better than kids in the countries they came from etc.

Wow. I‘m really impressed with your skill to interpret the data and build a narrative from it. However, let’s face it, it is just a convenient narrative with a faulty logic.
You cannot conclude that USA has excellent educational system if it delivers the great outcomes for certain advantaged subgroups. It’s logically incorrect and not how efficiency of education system is defined.

It is also wrong to compare black Americans and Africans and generally use non-scientific racial divisions which do not exist elsewhere in the world. Most of black Americans are no more immigrants than white people. They are simply Americans and should be compared to Europe the same way as whites.
> I don’t understand what this means.

In some (many?) countries the options for private healthcare are limited (by design) and public healthcare takes care of people. Not in USA though. :) It has its pros and cons, but to be honest, neither system works very well. I would pick a public one anytime, but maybe it's just because I know it.

> Why would 99% of people do this work if they cannot profit?

They do profit, and should - they get a paycheck for their work.
SQLite didn't just say, "it's public domain."

They explicitly state, "Anyone is free to copy, modify, publish, use, compile, sell, or distribute the original SQLite code, either in source code form or as a compiled binary, for any purpose, commercial or non-commercial, and by any means."

One can buy a "license" if one's company is run by idle lawyers: https://www.sqlite.org/purchase/license

You can have a memory safe SQLite today if you compile it with Fil-C. Only tiny changes required. I almost have it passing the test suite (only two test failures left, both of which look specious).

Somewhat offtopic, but I noticed that ChatGPT in a Firefox tab makes Firefox unstable. Often when Firefox misbehaves, I close the ChatGPT tab and things go back to normal. Did anyone else notice this? I'm running Firefox on Ubuntu 22.04, 64bit Intel, and I have plenty of RAM (64GB).

> SIPC protection covers against a brokerage firm failing, which in our case is Apex Clearing. We are not currently a brokerage so SIPC would not apply if Double goes bankrupt.

I thank you for being upfront and honest about this. The tough spot you'll find yourself in, then, is that if any money goes missing between you and Apex, customers are completely SOL. This is not a theoretical risk, this is exactly what happened in the Yotta/Synapse fiasco. Even if I trust that you guys are much better technologists than Synapse, would I be willing to take that risk for a teeny, teeny reduction in fees compared to an index ETF? Sorry, not for me.

EDIT: Wanted to put an edit up here so that it doesn't get lost. Thanks for your response below - for me, that was the critical information I needed, that I can directly verify that my SIPC-insured funds are held by the SIPC-insured entity. That was indeed not the case with Yotta/Synapse (and, indeed, most fintechs who keep customer funds in an FBO account at a partner bank), so I really appreciate the clarification. FWIW, I think it might be worth it to add a small blurb in the "SIPC Insured" section saying that your insured funds can be verified at any time.

Kudos, you guys have thought through a good deal of the important details, and sufficiently assuaged my concerns.
So, as in america, again, you're guilty until you prove you're innocent, by either wasting a lot of money on legal costs, or alternatively, letting them steal whatever they took from you...

sad.
It's hard to say. For example the Google's paper talks about some rare (once an hour) strong errors. Are they fundamental or have some easy fix? We don't know.

One obvious problem is cooling. We can't cool million qubits in a single fridge, so we will need to split them between fridges and communicate. Also, the wiring is really complicated already and hard to scale (one reason IBM has heavy hex is to have more space).

Another problem is connectivity. For transmon qubits connectivity is fixed. Applying gate to two far qubits requires a lot of swaps, which is expensive. This is less of a problem for ions or cold atoms because they can couple any two qubits; but they likely wouldn't be able to for large amount of qubits.

Another thing is classical control, because the classical data needs to be processed at high speed. Some companies develop specialized hardware for that.

None of these is necessarily fundamental, but these problems need to be solved, in addition to usual scaling (it is hard to manufacture these devices and it becomes harder with each qubit).
The full pivot to products is another tell that they don't have high hopes on AGI
I'm foreign to the US and no longer work there (Thanks to Trump, literally and directly.)
While I was there... I literally worked for an insurance company. I have also done work for a pharmaceutical company.
The motivation in healthcare in the US is purely profit. It is not like that anywhere else in my experience.

This is a nonlinear filter because of the way alpha is determined. Since this is in SIGCHI, I assume the actual novelty here is "this filter has behavior that feels right to interactive users, (and is also computationally cheap)".

> and your likelihood of ending up in either is 50%.

I don’t quite agree with this characterization. You end up in both universes with 100% certainty, but there will then be two of you, one in each universe. Where the likelihood again comes in, is when one of the two yous wonders in which branch they are located, and tries to predict (retrodict?) based on information collected prior to the branching, it will be a 50/50 likelihood. Of course, if they are able to look at the outcome of the experiment, it will become clear in which branch they are located.

This concept of probability in the context of MW is known as “self-locating uncertainty”: https://www.journals.uchicago.edu/doi/10.1093/bjps/axw004
In the world of legal consequences it is not.

DBOS Co-founder here. Great question! The big difference is that DBOS runs as a library inside your program, whereas the Temporal architecture is an external workflow server managing tasks on distributed workers. The advantages of DBOS are:

1. Simpler architecturally. Just a normal Python process versus a workflow server coordinating multiple workers.

2. Easier dev/debugging. A Temporal program is essentially distributed microservices, with control flow split between the workflow server and workers. That complicates any testing/debugging because you have to work through multiple components. Whereas DBOS is just your process.

3. Performance. A state transition in DBOS requires only a database write (~1 ms) whereas in Temporal it requires an async dispatch from the workflow server (tens-hundreds of ms).

I lost thousands of dollars with Snyapse's collapse, and there's still no update on getting any money back. It is a real concern, and something many are pushing on to regulate + rule over, but so far there's no bite.
What need is that? Bad people with malicious intentions exist: therefore, remove something that functions properly.

DNT is not shilled by some privately-owned company that claims it will somehow, "Make users invisible online for the low, low price of (money)!" Instead, it is simply an HTTP header that some (many) websites ignore, or outright maliciously exploit for personal gain.

Computer Operating systems are not "false advertising" simply because certain programmers ignore standard practices outlined by the maintainers. It is not the fault of an Operating System if programmers refuse to adhere to the documentation on how something should be implemented. It's certainly not a sensible justification for Operating Systems "needing to go", just because people write bad or malicious software to abuse an OS's weaknesses.

To be clear, I am hardly saying DNT is a good option, precisely because so many websites have ignored or abused it in the past. I am simply saying DNT should be an option, and that it should be one that is enabled by default.

>If you can find someone and successfuly sue them for not honoring it great - but you still need to do a lot more (sue many others in many countries).

If DNT is removed as being an option, what need would there be for such a law to be created in the first place? You said you support the idea of a law being made - shouldn't you be for DNT remaining, then? I hope that doesn't mischaracterize your point but it's a little confusing, it sounds like you're saying you: support the premise of DNT, want a law to enforce DNT...and you don't want DNT as a configuration option in Firefox.
Yeah, our vision is calibrated around blue and yellow - knowledge about the color blue is in our DNA.
On the flip side, I do think that passively consuming "edu-tainment" content is better than consuming, say, fictional sitcoms or dramas that are intended to appeal to the masses. Not that there's anything wrong with consuming "mindless" entertainment either, just that in a conversation about productivity vs non-productivity and "consumption"'s effects on it, I think it's fair to rank the content in question.

I watch a ridiculous amount of this type of content. As a "maker" myself, I get inspired by watching other people make stuff .. and I pick up a few tips and tricks along the way too.

But, the trap here that a lot in the comments seem in-tune with, is the trap of deluding yourself into thinking that you're being productive by consuming content ... as opposed to, well, producing stuff.

My wife and I are part time performing magicians, and when it comes to our magic act we fall into this trap a LOT. Because I make good money as a software engineer, I wanted to create for us a "library" where no matter what we want to write or create we will have resources that will empower us with method possibilities. Sounds great on paper, until we look back on what we accomplished in the past weeks and all we can come up with "Well, we read a bunch of books... and some are super expensive and hard to find out of print magic books that only have < 1,000 known copies in existence ... does that count?"

No, it doesn't. Some of the most innovative inventions and artistic creations have been borne from scarcity and limitations. An over-abundance of information is not necessarily bad it's just that we tend, as humans, to find ways to trick ourselves into thinking we're accomplishing something when we're really being passive.

To circle back to my original point, while watching "edu-tainment" content on YouTube is still being passive, at least there is the capacity to gain high-level knowledge that can give you a head's start when you're ready to actually start diving into doing something.
We explicitly test 1.28+. But I have in front of me a 1.27.13 and the operator works on it without issues. And probably goes way further back than that.

i would guess "full memory safety" is going to be impossible, at least at compile time. I'd guess that if for no other reason than performance SQLite uses data oriented techniques that effectively reduces pointers to indices, which will no longer have ownership or lifetime tracking in the rust compiler.
According to the chart, the American scores amongst the internationally high performing demographic categories are exceptional. The overall score is only dragged down due to demographic categories that perform low internationally.
Have to admit the immigration comment also triggered my "blaming immigrants" radar. After a careful reading it was an honest attempt for more information or clarification on how the details might be better interpreted. Something people should do more of when statistics are used as evidence. Actually a very good question.
The fundamental problem with Wikipedia is that reading one article edited by a dozen people with different perspectives and opinions is just not as illuminating as reading a dozen articles, each written by one person.

That's why all serious researchers need access to the primary literature, original research reports, reviews of collections of reports, all clearly attributed to known sources. If you're working in the field you'll also know about the biases of the lead figures and can take that into account in your reading. Wikipedia is a mess in comparison, it's just for entertainment.

There is an additional option: the person pays for it. Or someone else pays for it. Since the 1980s U.S. emergency rooms have been required to provide life-saving care regardless of whether someone can pay.

It is not violence to fail to reimburse someone.

If someone cannot pay his bills, then he declares bankruptcy, the debts are wiped out, his creditors take a haircut and he moves on with his life. In many/most states he will get to retain his home and perhaps his vehicle. It’s not the end of the world?

Show HN: Crosshatch – Privacy-First API for AI Personalization
Hi HN!

We’re launching Crosshatch, an API that enables privacy-compliant AI personalization using authenticated user context.

The Problem: AI models lack user context for truly tailored experiences. Meanwhile, direct data integration creates privacy and compliance risks.

Crosshatch lets apps personalize experiences without handling raw user data. We shipped a pre-built authentication allowing users to explicitly connect data sources (e.g., Gmail, Calendar, Plaid) to Crosshatch for your app's specific use-case and a secure AI proxy, so that apps can integrate inferences from user context without accessing the raw data.

You can add the Crosshatch Link to your app with our SDK. Once a user links data, you can make API calls, specifying prompts, LLM, and context in SQL-like queries. Our proxy enriches prompts with queried data and returns the AI-generated response.

We use AI as a privacy-preserving integration layer: a personal AI agent. Apps receive AI-generated insights (e.g., “user prefers boutique hotels”), not raw data. Processing occurs entirely in our VPC using models like GPT-4, Claude, and Gemini.

Technically, when a user links data we turn on a continuous sync. Linked data is transformed into a unified events representation to enable consistent querying (and eventually permissioning) across data types. We're shipping webhooks in January to enable developers to get notifications whenever context changes.

Crosshatch is like an opinionated MCP server that enables LLM Sampling of private context for users without compute.

We ship features like managed oauth flows with continuous context sync, a unified events representation for consistent querying across data types, and webhooks to enable AI notifications whenever context changes.

Crosshatch is free to get started and charges usage-based fees.
You can try it at platform.crosshatch.io or check out our docs at docs.crosshatch.io

There's much to build here – we'd love your feedback!! Are there apps or example use cases you'd like to see us build out?
Bit disappointed, looked for .net core support but no.

Languages that are supported: Typescript and Python. I know programming languages as a topic is as inflammable as religion, but boy do I feel sad that these two are considered the most important these days. For server applications.

Anyways, can people here recommend alternatives with bindings for .net core?
Yes, it is a leads driven business. I have focused on improving SEO in three of their core markets. Any new customer that signs up as a result of my marketing efforts, as long as their base margin is met, I get paid for the lifetime of that account.
I think we are well at the point where it is just time and money. Its not a physics problem its an engineering problem.

I'm sure there are lots of complicated problems ahead, but i don't think we are waiting for someone to discover "new" physics.
author here: fully compatible at the language and file format level.

Further down the post I actually call out explicitly that we do intend to get rid of some of the baggage.

Regardless of all the internal drama, you've gotta hand it to their product team - they know how to ship. Personally I find their canvas tool best in class and some of these new features seem absolutely awesome. WASM python? This opens up so many possibilities and it seems likely they're building towards Bolt.new competitor.

On that vein, it seems like every time OpenAI launches something it becomes table stakes for all the other players. I have no idea how Mixtral or any of the smaller companies will compete long term.
