They don't cite a paper to show how it works, but if the graphic is something they came up with, then I'm skeptical. The graphic indicates they pack the memory more efficiently, which is a solution to the packing problem, which is notoriously difficult to do optimally.

EDIT:

Checking their CTO (Angelos Arelakis [1]), they do a lot of work on compression [2]. Their most cited paper seems a lot like what they talk about in the article:

Arelakis, A., & Stenstrom, P. (2014). SC2: A statistical compression cache scheme. ACM SIGARCH Computer Architecture News, 42(3), 145-156.

Checking Sci-Hub, the paper is about a cache device that uses "Huffman-coding" [3] for performance improvements at the memory level. Which seems interesting, but it's a statistical cache, and so the ~50% savings they talk about in the article is probably the average case, rather than some super-revolutionary "perfect" system.

> Honest question, can you give me an example of thinking or reasoning that happens fully independently of reasoning via symbols or their manipulation?

I don't think we have anything but subjective, indirect understanding of how thinking happens, but I think that, at a minimum, what we describe as "reasoning" specifically is tightly conceptually related to, if not a subset of, manipulation of abstract symbols to which concrete experiences may be approximately mapped.

I'm not sure I'd say this is the same thing as language, but there's at a minimum a shared common symbol-manipulation underlying both. Do the capacities always come together? I'm not sure how we would know that, I think our ability to recognize reasoning is tied to it being mapped to language, and are ability to distinguish something as language rather than nonlinguistic signaling or mimicry of something else that is using language is tied to independent expression of reasoning through it.

I think a reasonable barometer for a lot of news is: will this be important or relevant in 1 month? If the answer is "no", then it's probably more entertainment than anything else.

However if I were to try and steelman the opposition for your position, I'd probably explore the argument that you could be living a very privileged life which might be part of the reason for why you're able to ignore the news. For certain vulnerable groups, keeping up to date with politics and the news might have a tangible impact in their everyday life.

With that being said, I generally don't keep up with the news either.
That story is from 2021, which is before Musk purchased Twitter.
China has made the most nukes in the past decade than any other nation in the world.

China has also dramatically increased the size of its military fleet, released movies (Wolf Warrior) to build nationalistic zeal and it's Diplomats have taken a liking to that nationalistic / aggressive stance.

There is no 'projection' here. It's simply acknowledging that China's war investments have grown dramatically and it's own diplomacy has shifted as a result.

Speaking as an SO contributor, I'm perfectly fine with having an LLM read my answers and produce output based on them. What I'm not okay with is said LLM being closed-weight so that its creator can profit off it.

Yep, that’s what I figured! And hence my original post at the top of this thread, suggesting that it’s easy to feel like we have sort of “solved” solar from a panel efficiency perspective and it’s everything else that we still need to improve on (grid infra, storage, etc etc), and additional percentage points of efficiency won’t really mitigate the existing limiting factors.

> To provide the best search experience, we need to collect data. We use web crawlers to gather information from the internet and index it for our search engine.

> You can identify our web crawler by its user agent

To anyone who's familiar with web crawling and indexing, these paragraphs have an obvious meaning: Perplexity has a search engine which needs a crawler which crawls the internet. That crawler can be identified by the User-Agent PerplexityBot and will respect robots.txt.

Separately, if you give Perplexity a specific URL then it will go fetch the contents of that URL with a one-off request. That one-off request does not respect robots.txt any more than curl does, and that's 100% normal and ethical. The one-off request handler isn't PerplexityBot, it's a separate part of the application that's probably just a regular Chrome browser that issues the request.

> Sure, your second infection might be like a cold, but the third could do you in for good.

I don't think there's evidence of this? Long COVID doesn't 'do you in for good'. The only evidence I'm aware of is that subsequent COVID infections tend to be less dangerous, not more.

But none of this is relevant to my point anyway, really, which is that COVID is not the only virus capable of causing these kinds of effects; it's increased the incidence, but the underlying phenomenon is the same and won't go away if we get rid of COVID somehow.
Blogger siderea has talked about this a lot in relation to patreon, and the challenges for any platform wanting to replace it.

Apparently it comes down to how card processing fees work, as long as there's a constant fixed cost per payment (whether or not there is also a percentage fee), "microtransactions" become uneconomic for the platform.

Apparently the problem with letting people pay say $10 into an account and then dispense $1 a time to read articles is that makes you a "payment processor" in some states which comes with strict regulations and extra costs.

For interactive navigation on a sphere (remember, this is just a sphere looked at from the inside) you actually want absolute euler angle based rotations, otherwise compound rotations around any closed loop on the sphere's surface will change the orientation of the camera and make further navigation extremely confusing.

>> In a world where users ask Perplexity these Help questions about my SaaS, Perplexity may answer them and I would lose all the insights because I never get any traffic.

Alternative take: Perplexity is protecting users' privacy by not exposing them to be turned into "insights" by the SaaS.

My general impression is that the subset of complaints discussed in this thread and in the article, boils down to a simple conflict of interest: information supplier wants to exploit the visitor through advertising, upsells, and other time/sanity-wasting things; for that, they need to have the visitor on their site. Meanwhile, the visitors want just the information without the surveillance, advertising and other attention economy dark/abuse patterns.

The content is the bait, and ad-blockers, Google's instant results, and Perplexity, are pulling that bait off the hook for the fish to eat. No surprise fishermen are unhappy. But, as a fish, I find it hard to sympathize.
And it has a lab course to go with it!

No, it is not. If James Taylor has a strong interest in singing, it is not wrong to say he sings flat. It can be mean to criticize people for things they cannot change, but it's hardly wrong.

What a solid reinforcement of the idea that birth is the way to be loved by the British elites. One could paraphrase Amis and ask "How do you get from a rented room in Whitechapel to a freehold in Knightsbridge? You get the keys from your family's trust fund manager."
> until the content goes stale, anyway

This will be quite interesting in the future. One can usually tell if a blog post is stale, or whether it’s still relevant to the subject it’s presenting. But with LLMs they’ll just aggregate and regurgitate as if it was a timeless fact.
I would rather be zapped with a 240v AC current vs 240v DC current.

AC power crosses the zero line twice per cycle while DC does not. AC has a lower ‘let-go’ threshold, but DC contracts your muscles and makes it harder to let go.

You are correct though, if you de-energize your panelboard and have a deadfront cover over the line side conductors and lugs, working inside a panelboard (or on electrical wiring) is safe.
If this even remotely resembled “looking at the sky” I seriously doubt there would be much demand or response to it. Fortunately, for the less incurious among us anyway, that’s not what’s happening here.

> I think there is a real content dilemma here at work

It's not really a dilemma.

This is exactly what copyright serves to protect authors from. Perplexity copied the content, and in doing so directly competes with the original work, destroying it's market value and driving the original author out of business. Literally what copyright was invented to prevent.

It's the exact same situation as journalists going after Google & social media embeds of articles, which these sites propagandized as "prohibiting hyperlinking", but the issue has been the embedded (summary of the) content. Which people don't click through, and this is the entire point of those features for platforms like Facebook; Keeping users on facebook and not leaving.

This is why quite a few jurisdictions agreed with the journalists and moved to institute restrictions on such embedding.

By all practical considerations, perplexity is doing the exact same thing and trying to deflect with "we used an AI to paraphrase".

> The incentives of Google and website owners were more or less aligned.

The key difference here is that linking is and always has been fine. Google's Book search feature is fair use because the purpose is to send you to the book you searched for, not substitute the book.

Google's current AI summary feature is effectively the same as Perplexity. People don't click through to the original site, the original site doesn't get ad impressions or other revenue, and is driven out of business.

> What will happen if:

What will happen is what already is happening: Journalists are driven out of business, replaced by AI slop.

And then what? AI needs humans creating original content, especially for things like journalism and fact-finding. It'd be an eternal AI winter, all LLMs doomed to be stuck in 2025.

It's in every AI developer's best interest to halt the likes of Perplexity immediately before they irreparably damage the field of AI.
Equation of exchange is a cornerstone of economics

The monetary side is Quantity of Money times Velocity of money. Both affect inflation. It is therefore Possible to have inflation with fixed money supply.

The business model was dual revenue streams: subscription (or a la carte day-by-day or month-by-month) + ad revenue, with a few exceptions like broadcast TV (where the coverage tended to be more shallow and lowest-common-denominator compared to the early days of cable TV news).

The online advertising merchants realized they could "curate" and "summarize" the articles, resulting in far fewer ad impressions than if someone had to find things purely through the publication newspaper, and bring the ads forward to their portal instead of solely on the content itself.

AND they capitalized on an early reluctance to charge for things online to push the "ew, who wants to pay" mindset globally.
I assume that design based on something like TPS92411 actually ends up being cheaper and more reliable than various series capacitor constructions, while being dimmable just fine and without spewing EMI. So it is just question of the OEMs having one 10 year old design and still using it.

I'd like to know more about the tumor killing mechanism. The article suggests it's due to the DNA destroying effects of radionucleotides. But these hot grains also produce heat. Many tumors are heat intolerant. Also, cancer cells are hideously good at surviving and rebuilding after genotixic stress. It can actually accelerate acquisition of treatment resistance. Genomes shatter and oncogenes recruit replication machinery amplifying to 10-20s copies in a couple cell divisions.

I used to study nematodes. We routinely used infrared lasers to ablate sub cellular structures like a neuronal axon or dendrite. These multiphoton lasers use 5-6 ultra weak beams and are only destructive where they converge. Which can be a cross section as small as a few nanometers. The worms are transparent and microscopic so you can easily see all their cellular structures under a microscope. Hopefully ML will boost radiography resolution enough we use this kinda of tech on people.
no, more efficient solar panels at a given price mean cheaper energy, which means it becomes economical to use more energy, until you run out of ways to use energy usefully. usually the increase in energy demand is more than enough to increase the use of inputs, a fact known as the 'jevons paradox'

Slicing economically (oversimplifying here and ignoring other certain types of vulnerable or feeling-under-attack groups) the people at the bottom and the people at the top don't generally need to worry about the news. The ones at the top will be fine either way. The ones at the bottom will continue to have to scrap along either way. It's the people in the middle who's level of comfort day-to-day could be most affected by political changes, for whom a change in tax rate or inflation or social subsidies could shift comfort into precariousness or vice versa.

The lab course is getting harder to run since the parts in the BOM on the author website are being end-of-life'd. I ran into this when I started trying to run it as a self-study project a while ago. It wasn't always clear what parts you could use to replace them either...

Also, the BOM itself doesn't have everything used in the course, so I sometimes found I needed to order something I hadn't anticipated needing. (the frustration with this ultimately caused me to drop it, maybe half-ish of the way through)

This doesn't really negate your point, the lab course certainly still exists, I'm just not sure how amenable it is to run through as a self-study hobbyist.
