That's like calling a CRM app "Wiki" because you like the idea of collaborative editing of knowledge (in a world where Wikipedia already exists and is synonymous with wikipedia.org). Like... sure, no one can stop you, but it seems both counterproductive to your own marketing and mildly disrespectful to the other projects that are closer to the original ethos behind the name. It's not that hard to name things uniquely, at least call it "Memexa Code" or something.

Do you have a horse in the race here, so to speak?

Wikipedia [0] has the following to say:

> According to Frank Edgerton (2002), the claim made by some authors that al-Jahiz was an early evolutionist is "unconvincing"

> If certain historians have claimed that Jahiz wrote about evolution a thousand years before Darwin and that he discovered natural selection, they have misunderstood.

A dollar spent is a dollar spent, but GDP is about production, not spending. If you spend a dollar for 1 iron nail or 1 dollar for 100 iron nails, it is not the same production even if by dollar measure it is the same value.

Governments are usually very inefficient. Corporations are also inefficient, but it is not the topic. The point is that we need to look more to the outcome than the money "value" because some governments made-up work has no value, but if you include it in GDP you inflate the GDP falsely.
Show HN: Mind Jam – Analyse YouTube comments to reveal

This is one of those industries that attracts cosplayers, but they expect to be paid. It gives me fake-cop-car-guy vibes.

When I was growing up I worked at a record-and-tape store. One of my co-employees was a fake-cop-car guy. It was really awkward. Sometimes he would show up “in uniform” just to “check on things”. It was cringeworthy at a sphincter-clenching level.

>So upon check out you're just getting a fee and sometimes it's egregiously high and sometimes it is nonexistent? If you're buying a $100 item (and let's say a $50 cost basis) that has three versions: US made, Japanese made and Chinese made you could get a $0 fee, a $5 or a $50 fee.

It would be more obfuscated than that. They're scummy, I didn't say they weren't clever. A company probably wouldn't make the exact same product in three different countries and Amazon probably wouldn't stock all three, they'd just pick the version they could make the most money on. Also, they probably wouldn't make the difference obvious, just a few cents or dollars here or there. They would say the tariff is $5, when it really was $4.50 and they'd just round up. At scale that really ads up.

>Seems like a very fast way to completely lose the trust of your customers.

Most of them lost trust a long time ago. I mean, what companies do you trust? I don't trust very many, if any.

Maybe I'm wrong, maybe we should all trust Amazon...

Edit: Amazon said displaying tariffs was never approved and won't happen. More junk news.

> When the government spends your money, you don't get to decide whether a particular transaction is good value.

And here's the root. That is an argument from principles of libertarian morality, not economics. It's fine if you want to claim that it's immoral for the government to tax and spend your hard earned assets. I just won't engage, because that's tiresome.

It's not fine to claim that the government stealing and spending your Lockian Sacred Property is "not productive" in a discussion about economics, because that is a word with meaning in the field and you're using it wrong.

(Edit: as stated, I'm not going to engage in a discussion on libertarianism in an economics thread. I'm merely pointing out that you have the economics wrong.)

I saw some project that used a DNS TXT field to check its version

That way I guess you get the caching of the DNS network for free, it uses basically one packet each way, encryption is still possible, and it can reduce the traffic greatly if a big org is running a thousand instances on the same network

This is a great point, I was just using it understand various DMV procedures. It is invaluable for navigating bureaucracy so if your job is to ingest and regurgitate a bunch of documents and procedures you may be highly at risk here.

That is a great use for it too, rather than replacing artists we have personal advisors who can navigate almost any level of complex bureaucracy instantaneously. My girlfriend hates AI, like rails against it at any opportunity, but after spending a few hours on the DMV website I sat down and fed her questions into Claude and had answers in a few seconds. Instant convert.

"empty field with fewer variables and greater proximity to demand"

I do not disagree with what you wrote but would like to suggest that empty fields are not necessarily the best place. I think rooftops and parking lots are better alternatives. They can then serve more than one purpose (shade). The empty fields can then stay empty (green spaces have value) or used for some other development.

O3 gave me basically that solution. "Below is the shortest safe schedule that really works ‒ but it assumes the boat can hold the man plus two passengers (three beings total). If your version of the puzzle only lets him move one passenger at a time, the puzzle has no solution: at the very first trip he would always leave at least one forbidden pair alone."

the perovskite material is currently impossible to put into service as it degrades instantly when exposed to ambient conditions, and there is no word yet on a perfect hermetic sealing technology to protect it. so this should read as an attempt to leverage the current anti china (market cornered for good,cheap, solar), into a pivot towards something that has been stuck on almost for 15 years now

And now Meta knows your location at that time, can use that lovely menu to derive ads better suited for its competition, has data on when you like to eat out, who else was there (let's not forget about DeepFace!), etc. While you ate your meal, you fed some juicy tidbits to their data repo on you and those around you.

Oh, hey, is that an ad for a local winery?

I moved to Kagi when Chrome moved to end Manifest V2. I am aware of workarounds, but I have really been moving to de-google my life. Honestly, I have been happy with the results and I think it's good to have various competitors out there. I even use Orion Browser for most personal browsing, and it has been acceptable with a few bugs here and there.
by righthand | 2025-04-29 15:47:24+00:00
How does it know the affordability of a menu item? If it’s only looking at a menu the odds are that it doesn’t have a lot of information such as serving size and calorie cost. You just asked an AI to give the statically correct item for affordability.

The wine it chose was how far down the list? Was it chosen at random or did it just match “chicken wine” with the first result?

This seems like you’re assuming the glasses help you decide but really it probably did what anyone would do and pick a random option or just give you the popular choice. Why even use glasses for that and instead just point somewhere on the menu?
by jjulius | 2025-04-29 15:47:46+00:00
Unless I'm really watching my budget (though, why would I be eating out at a place with a huge wine list and buying Meta glasses if that's the case?), I cannot possibly imagine the joy behind having a nice meal based on what AI told me is "the best deal" rather than trusting my own palate/gut and ordering what I know will bring me the greatest pleasure (or working with the sommelier to discuss my tastes and find something best-suited to both myself and my choice[s] of food).

You do you, by all means, if it brings you the most joy. But removing my own agency while allowing a company to track my entire dining experience to better serve me ads sounds so... hollow and dystopic.

>Heart disease deaths worldwide linked to chemical widely used in plastics

First thing I thought of is how much DEHP is used is the hospital, including for medical devices implanted in the heart. Such as pacemakers, catheters, stents and valves.

DEHP as a component is something like 30% of flexible tubing used in a hospital setting.

Phthalates leach because they aren't integrated with the base plastic by design - that's how they work. Phthalates sit in between the polymer chains (such as PET), rather than being bonded to them, which is precisely what affords that material flexibility, and also why they leach so easily.

When it comes to micro optimisations the issue is partly our usual tools in algorithm analysis and hardware intuition are very far apart. Random accessing memory is very slow compared to linear, some branches are considerably worse than others and it's actually quite hard to predict how much you can improve the low level details before you start, especially for big changes. Our tools can show us where time is being lost in inefficiencies but can't help us predict how changes will improve things.

> Indeed, even in the worst-case scenario, the average annual global mean ozone loss is found to be between 0.17×10–4 % and 8×10–4 %, while the Antarctic local ozone concentration change can reach about 0.05%. Those impacts are negligible when compared to the impact of anthropogenic activities, in particular emissions of industrial halogen-containing substances such as CFCs, that caused a global ozone loss of 3-4% (since 1970).

My dentist already uses something called OverJet(?) that reads X-rays for issues. They seem to trust it and it agreed with what they suspected on the X-rays. Personally, I’ve been misdiagnosed through X-rays by a medical doctor so even being an LLM skeptic, Im slightly favorable to AI in medicine.

But I already trust my dentist. A new dentist deferring to AI is scary, and obviously will happen.

If you want to get a sense of which foods could be high in DEHP, you can go here

https://www.plasticlist.org/

and sort by the "DEHP" column.

If I understand correctly, an RXBAR could have up to 1% of your tolerable daily intake for DEHP, and most foods are well below that.

Based on the OP, it seems like DEHP might be a bigger issue in developing countries.

I'm of two minds about this.

On the one hand, this is egregious and should not happen. People should not be stalked and lied to, and communities should not be manipulated at this scale.

On the other hand, it certainly already happens as it is incredibly easy for any group to use LLMs and do this. So the process and effectiveness should be studied and reported to the public... There might be a better way to do it though?

What would a junior developer be doing? Genuinely wondering what you would pay a junior developer to do today which couldn't do more cost effectively with AI? If you're talking about someone with a bit of technical knowledge who's cheaper than hiring a senior dev to prompt/manage AI agents then, yeah, I suspect there will be people doing this, but I don't think these are junior developers.

In my opinion there would be no point in getting junior developer to do anything right now in the same way I'm not going to pay a rookie artist or web designer to do anything for me anymore because I'd get better results from AI. Obviously companies which are not productivity and cost optimised might not care/realise they can do this right away (there will always be the odd inefficient hire here and there), but my guess is that 99.9% of these hires make no economical sense and will be so few and far between that the role will effectively be eliminated in place of something else. And this happens often in tech. I used to know "webmasters" who just did HTML/CSS. The web still runs on HTML/CSS, but those jobs no longer exist and people who used to do that work are now doing other things. Again why the hell would I pay someone to write HTML/CSS when there are plenty WYSIWYGs and AI tools which could do a better job, cheaper and quicker?

>> the increase in autism

> Is largely illusory.

Huh? First off autism rates are provable increasing in the US. It is multi-factor for sure that includes increased awareness and more access to autism tests, but...

It is a proven fact that older fathers have a higher change of having offspring with autism [1] and it is also a fact that in the US (as like many places in the world) men are having their children later [2]. Together these two accepted scientific facts lead directly to increasing autism rates, no? Or do you disagree with this reasoning?

The link I am positing but there isn't quite as much acceptance is that sperm degradation that leads to autism, isn't only caused by age but also influenced by plastics.

On top of the news headlines being shoved in your face everywhere in Windows, they do the same with stocks, showing you trade values of random stocks in various places which I can't help but find hilarious.

I think they're trying to emulate Apple who has had stocks integration by default for years, including being alongside the other pre-installed apps like SMS and Mail on the first iPhone. I imagine Apple did it to cement themselves as a high-class lifestyle brand, even though I'm sure there was never a time where most iPhone users were doing a lot of day trading.

I wonder what percentage of Windows users rely on the stock ticker in the start menu though...

I do all searching from the command line. No browser. It's funny but I feel like google.com, both www and news, are faster in recent months, specifically, after Google began blocking requests with certain user-agent strings. Because I search from the command line, I do not get any "AI" answers. Obviously command line search is faster than browser-based search. But what I am observing is that command line search now seems even faster than it was in the past.

I only have good things to say about Kagi. The search results are better, I can block or downrank SEO slop while increasing the rank of sites I like. There's no advertising anywhere, no sponsored results, no AI hallucination taking up the whole top quarter of the page.

But the most important part is that it's very likely that there will _never be_ sponsored results. The business model means their incentive lines up with mine - give me good search and I'll give you ten bucks a month. If your search starts to suck, I'm not going to keep paying.

It's astonishing how much community goodwill and excitement there was for llama when it first came out, and how much it has plummeted since then.

Partly the sheen has worn off, and of course there are other interesting "open source" llm offerings now, but I don't think it can be overstated how much Meta is just a toxic brand.

Or just actually write proper automated tests for basic features first, before a large refactor to prevent introducing issues like this from happening again?

While I respect the author's honesty in this mistake, the main takeaway here is not mentioned and that is just writing proper automated tests as their impression on this post is that there aren't any.

None that will make you happy. The market changed a lot, I myself not sure if I will be able to find contracts (I'm a contractor) for the next 20 years. The alternative isn't terrible tho: you gotta create your own job, contracting and then creating your own business online. The best way to prove remote works is to create jobs and hiring remote. Nobody should think they are entitled for a great remote job forever.

Good article that I agree with mostly. One interesting note is this:

> There is no way to provide both optimized assembly and equivalent C code and let the compiler use the former in the general case and the latter in special cases.

This is true, but can be seen as a failure of language and tooling. For example, Halide [1] pioneered (AFAIK) the concept of separating algorithm from implementation at the language level. This separation lets you express the algorithm once, and then "schedule" it by specifying parallelism, vectorization, etc. You can provide multiple schedules for one algorithm, which allows you to specialize / make different choices depending on varying factors.

It's a really interesting concept, though maybe limited in practice to DSLs. I'm not sure a general purpose language would be a good fit for this model, but then, for general purpose programs written in general purpose languages, perf optimization at the level TFA discusses is frequently limited to just specific hot sections. Those hot sections could be extracted out into specialized components written in such a DSL.

It depends heavily on their market incentives. If the local power company is also in charge of the wires, less load on the wires means less cost. In a market where distribution and generation are different operations, generation only cares about whether anyone's going to buy the electricity they want to put on the wire and you saying "No thanks, I'm full" is in direct competition to their interests (and existence as a firm).

My account is currently on Fosstodon after the previous host shut down. While I don't agree with what this particular moderator said, I haven't seen their political stance affecting the instance itself. From the discussions, it looks like the moderator took care to keep their decisions free of their personal biases. Fosstodon is a relatively well managed instance and besides, much of my feed comes from other instances anyway. I don't know how bad the situation is, but I'm not very enthusiastic about yet another migration.

It's one thing to block an instance that allow trolls to repeatedly spam other instances despite appeals. But it looks like that isn't the case here at all. Fosstodon is (or was) home to several FOSS projects and developers. It looks like the fediverse hosting community decided to torch fosstodon and burn all its tenants because one of its moderators held views that they didn't agree with?

I want to highlight the ridiculous cancel culture that pervades the non-mainstream social media. I say this as a person with strong liberal views. Holding progressive views don't automatically give anyone the moral authority to punish others for dissenting views. Doesn't freedom of speech matter to the liberal side anymore? If you don't even want to see dissenting views, how do you recognize any flaws in your views? And the liberal community has plenty. The community seems to be to be demonstrating the same intolerant and authoritarian tendencies that victimized them earlier. Decentralized social media seems to have become a tool for decentralized censorship with a large area of collateral damage. If this is the demise of fosstodon, it will probably be that of my fediverse presence as well.
