I’m really surprised by the performance of the plain C++ version. Is automatic vectorization turned off? Frankly this task is so common that I would half expect compilers to have a hard coded special case specifically for fast dot products

Edit: Yeah, when I compile the “plain c++” with clang the main loop is 8 vmovups, 16 vfmadd231ps, and an add cmp jne. OP forgot some flags.

Sadly this article is, per the tradition over at Ars Technica, quite misleading.

Bottom line: if you want to understand the actual history of the online world, don't read Ars Technica. They don't get it, they've never gotten it, and you're just being fed mythology and selective history in the same mold as WIRED before it.

They should know better. The author of the article absolutely has no excuse. But still, they actually public "architect of our online age" when that is NOT what Ward was at all. He was a latecomer. The online world was already booming in 1978.
Why?

Most people (as in 99.9%) don't give a shit about venture capital and don't follow it at all. I would guess that most people (as in >50%) couldn't even give you a half-way accurate definition of it.

If you're buying enterprise software you're more likely to know that VC exists but you're not any more likely to care about it. None of the people writing 5-7 figure enterprise software checks are tracking which VCs are at which firm when, and who invested in what, and what company had a negative client impact when, and all that. And even if you were tracking it what are the odds that you'll need the same software 5 or 10 years later when it might be relevant to the decision?

Things evolve based on evolutionary pressures only and the VC world is too disconnected from its negative impacts to feel any pressure from them.

Put another way, credibility (from the standpoint of the customer) does not positively or negatively impact a VC in any way.

Show HN: Advanced LLM Voice Mode but on your own database
Hey there! We've been working on something pretty cool lately, and I'm excited to share it with you. It's called Zing Advanced Voice Mode, and it's designed to make data analysis more intuitive, accessible, and efficient.

With Zing Advanced Voice Mode, you can simply ask a question in plain English, and the tool will instantly provide a clear, concise answer, along with a visual representation of the query. No more struggling with complex syntax or spending hours writing intricate SQL statements.

It works with google sheets, excel files, csvs, postgres, mysql, Databricks, SQL Server, Clickhouse, BigQuery, RedShift, and more.

It supports calculations, filters, joins (no semantic model or foreign key needed) but not CTEs.
We’re working on making the voice better and reducing latency (currently takes 3-10 seconds typically).

Its available on iOS now. Android + web in a few days.

Would love to get your thoughts on how we could improve this!

Doubting Thomas went to India:

Christianity is India's third-largest religion with about 26 million adherents, making up 2.3 percent of the population as of the 2011 census.[1] The written records of St Thomas Christians mention that Christianity was introduced to the Indian subcontinent by Thomas the Apostle, who sailed to the Malabar region (present-day Kerala) in 52 AD.

Your personal anecdote/experience doesn't translate into everyone's reality.

Here's another anecdote: many ultra-rich people have committed suicide because they were unhappy. If money bought happiness, they wouldn't have done it.

Happiness is a complex thing. You can visit remote third-world villages and find people living very difficult lives yet very happy because that's all they know and don't bother comparing their situation with others.

>The safe levels are built around a model of the amount of water a human being can consume, both directly (drinking tap water) and indirectly (cooking, drinks made with tap water, etc.).

The epidemiological studies suggesting detectable harm at 1.5mg/L are from whatever amounts are actually consumed in affected areas, not some "model" of the max any person could consume.

Given the variety of human practices – preferences for packaged drinks, different food-preparation approaches, etc – the same tap levels could easily result in gigantic differences in net consumption among different individuals.

If the standard is half the "safe" level, but some people consume 4x or 10x as much tap water, & perhaps even have a higher baseline of non-tap-water flouride consumption, then some percentage N of the population could be developmentally-harmed, even at levels "safe" for "most". How high of an N should we accept for the modest benefit of fewer cavities?

Your link shows no public benefits other than less tooth decay, doesn't compare flouridation to other interventions, & doesn't weigh costs versus benefits.

If I'm reading its "DMFT Index" ("Decayed, Missing, Filled Teeth [per capita]") values right, it also shows a very modest benefit: a "DMFT" of 0.06 in flouridated areas, and 0.115 in non-flouridated areas. Roughly, instead of one cavity-affected-tooth per 17 kids, there's one cavity-affected-tooth per 9 kids.

Yes, we should try to minimize cavities, but what N% of outlier-consumption overflouridated kids should get a 5-IQ-point drop for that marginal benefit?

What if we shifted the flouridation expense into reminding kids to brush or use a flouridated rinse? What if we just paid a cash bonus to kids who manage to avoid permanent-tooth cavities through whatever interventions work? (The same funds would go to treatment/amelioration for those who wind up with decay anyway.)

> Tough to tell, given nobody is turning a net profit on LLMs yet.

I suspect in the case of Meta and other big players, profit isn't necessary required to bring substantial value. Imagine their model being able to help them moderate more fairly and accurately. This alone could prevent potential legal actions from individuals, companies, and governments.

> If the data from supervised driving can he used for unsupervised driving

So you're unaware of the AI day presentations about their driving training pipeline. Learning about their engineering in that regard really changed my perception of the likelihood that they could solve the problem. Give it a watch: https://www.youtube.com/watch?v=ODSJsviD_SU

> failure to keep up with competitors like Waymo

Looks like each of them lead in different ways to me. Waymo leads within certain specific city limits, Tesla leads on the open road. These seem to be direct consequences of their engineering decisions. Question is which will converge on working everywhere all the time.
> Particularly, people were VERY critical of how slow java was and how much memory it consumed.

To be fair, those were totally valid criticisms before HotSpot got really good. IIRC, way back in the day Corel said they were going all in on Java for their software suite, and they eventually abandoned it due to performance.
> profit isn't necessary required to bring substantial value

They’re private companies. If they can’t tie it to profit, it’s not adding value.

> being able to help them moderate more fairly and accurately

This reduces legal costs and increases strategic flexibility. Sort of like HR or legal departments: cost centres add value by controlling costs, a critical component of profitability.

Our organization (the American Federation for Aging Research) is hosting a webinar with Jay Olshansky (author of the paper) and Andrew Scott, a leading economist in longevity to discuss Jay's results on 10/22.

Apart from the fact that "working age" doesn't mean the same thing in a world that has anti-aging interventions?

Our economic system is incompatible with the next 200 years irregardless of what specifically gets invented.

At 5%/year, that's a factor (not percentage) of 17292 growth; in energy terms that's not quite boiling the oceans, but it is making the poles the only barely livable zone.

In any sense besides energy, this kind of growth implies automation that makes the meaning of work radically different than today. Human or superhuman AI would be an example of that, but the successful creation of that has other complications that we can currently only guess at with less awareness than the Victorians had of climate change or biodiversity loss.
Does anyone know if there’s a simple solution to generating NeRFs from a continuous all directional camera (like a GoPro Max). It would be fun to make an explorable universe like that.

Ask HN: Is There a Name for This Diet Strategy?
I’ve been losing .5kg per week for 9 weeks (with a 2 week break for illness) using a strategy inspired by a Hackernews comment I can’t find now.

The only rule of the diet is “Don’t weigh more than your target weight for this week”. Then I lower my target .5kg each week.
It’s so much more consistent than counting calories, because that is very difficult to do accurately if you aren’t measuring every single ingredient you consume. Furthermore, I think it is teaching me a lot about my body and relationship to food because I’m developing an intuition for how much longterm weight vs short term weight a food adds. It’s also been easy to get back on target after over consuming for a day or two.

I just want to know, is there a name for this strategy or is this something novel?
Star Trek's First Space Battle Defined the Genre
I think it depends on a lot of factors.

I think the biggest issue would be the most "successful" VCs aka the ones that make the most money, have the most money to invest in other companies.

If they can make the most return on their investment by fucking over customers than they would have a greater impact.

I suppose if we had the ability to "pierce the VC veil" we could see who the main VCs are and choose weather or not to use a product based on their track record.
I've no idea whether this school has ambiguous rules, or enforces them inconsistently (as is seemingly alleged) - but the lawsuit questioning whether the school should ban the use of AI to complete assignments (when such use of AI is banned in many college and professional environments) sounds like total BS.

And at some point, I'd say that schools needs to introduce a new grade - "A*" - for such situations. At the bottom of the student's transcript, it would explain that "student's otherwise-earned grade was replaced with a fiat 'A', under threat of legal action, per school district policy". 100% truthful, but some university admissions officers might choose to read it as a red flag. Better to spend the district's limited funds on student education, not lawsuits.

You can use DuckDB WASM independently of Pyodide and can extend it with SQLite.

Though it seems to be somewhat limited. I couldn't even check what version it has, since sqlite_version() was missing. Version in the repository [1] is 3.38.1, which is from quite a ways ago.

At the moment DuckDB web shell can't load SQLite extension, since that hasn't been released for yesterday's 1.1.2. Earlier version does work using recently updated WASM edition. That can be extended with spatial including GDAL, vector search etc [2]. Making your own "SQL web shell" wasn't too hard, though docs weren't quite complete enough for me.

Did you read the article?

'The activist groups had a growing, but highly controversial, body of scientific evidence to draw from. Scientists had long known that very high doses of fluoride can damage bones and teeth. Since the early 1990s, a modest body of scientific research has also suggested that fluoride can harm brain development, leading to measurable drops in children’s IQ. Many of those early studies, experts say, were poorly done. And some took place in communities where fluoride naturally occurs in the water at levels much higher than the 0.7 milligrams per liter that U.S. communities currently add to their tap water.

Still, the signs of negative IQ effects were consistent enough for some experts to raise questions. “More research is needed to clarify the effect of fluoride on brain chemistry and function,” a panel of experts convened on behalf of the EPA wrote in 2006.

Starting in 2015, the National Toxicology Program, an office housed within the National Institutes of Health, began preparing a major review of fluoride research — at least partly in response to a nomination from the Fluoride Action Network.

Around the same time, the government institute that houses the NTP helped fund new studies in Canada and Mexico that looked at levels of fluoride in pregnant women’s urine, and then investigated whether those levels were correlated with a drop in IQ in their offspring. The researchers found some signs of an effect.

The results concerned some environmental health researchers. “As the literature continued to accumulate, we were more and more convinced that there were no single flaws that could explain the consistency in the findings,” John Bucher, a retired NTP toxicologist and a lead author of the report, told Undark in an interview conducted late last year.

In August, after years of delays, the NTP released its final report, finding, with moderate confidence, that fluoride exposures at levels above 1.5 mg/L “are consistently associated with lower IQ in children.”'

There are serious researchers finding mixed results based on the levels, not just crunchy social media accounts.

IMO the biggest detriment of VC-backed companies is that they can still get killed when they're profitable because they're just not profitable enough.

You found a company and own 100%. You get investment and bring on partners, you set aside 20% for employee shares, etc. All of a sudden there's a dozen owners and nobody owns 50%. You're profitable in the sense that everyone's payroll clears and you're making rent, with money left over, but it's not enough to invest in anything big, and the investors won't put up anything more because your growth has stalled.

Every investor who was previously your "partner" will be trying to shut the company down and sell it for parts.

VCs don't make their money by having a portfolio of companies throwing off $200k/yr in profit to a dozen different investors.
