Yep. Evolution is really just a description of the consequences of differential reproduction. Rare behaviors (adoption) that are not optimal but which are driven by drives (better motherhood) that may have big evolutionary upsides may simply not be selected against very effectively, and evolution is always limited by the pool of mutations and what is possible for the organism at that point. If there is no mutation that both eliminates adoption and preserves the beneficial effects of the drive, it may not happen...

This is the kind of thing that I sort of have the knowledge to jump into (I do power electronics by day) but have no will to actually pursue since hardware manufacturing in the US is very expensive to start, very hard to develop, very punishing to maintain, and very low margins even when you accomplish all that.

Trump talks a ton about "Bringing back manufacturing", but the dude is clearly using it purely for political points. Anyone in the industry knows the supply chains here are weak as hell, and anyone young with a brain is going to SWE or Finance. The industry today is held up by grey beards past retirement sticking with it because no else can do it.
pry is what I miss most when using other languages. I've used all kinds of debuggers all kinds of hardware with many different languages, and pry is by far the best tool for development and debugging. People talk about the REPL in Lisp for good reason, but pry takes that concept to infinity and beyond. When I think about the future of AI assisted programming, it's something much more like the pry interactive development loop than a code editor's suggestions.

Yeah, there's a lot of education you can't get just by reading books. Which is exactly why I ended up hiring a tutor.

Philosophy in specific is one long argument, 2500 years of new people showing up and saying, "Well that guy's wrong and I'm right." So much of what I needed to know to make sense of philosophical arguments is either hugely scattered or not written down at all. It was vastly more efficient just to hire an expert.

That's not to argue for the $150k education; I wouldn't know. But I don't think that taking life advice from fictional characters is much better.
I see this as a good measure.

I don't call for total abolishing of social "sciences" funding, but we need to stop putting real sciences and social sciences together in the same budget bucket.

1st, because the citizens are misled about the money that is actually making into real science.

2nd, because we hereby pass a message that when they hear the - now - infamous words "scientists claim", they will start being educated on if we are actually talking about proper scientists from physics, mathematics, biology, chemistry, etc, or some ideologue from sociology that was being paid by public funds to spread some political ideology by abusing the term "science".

Naively, I'd guess that the increased surface area from the cylindrical burr increases the retention rate since it's mostly caused by static cling. There's mention of a built-in knocker, but even with the dissected machine photos, I can't tell where that knocker is housed or how it would function.

How is this helpful? Not everyone can keep up with the rapidly shifting world of AI; it's worse than JavaScript. People have day jobs that don't revolve around AI and don't have the bandwidth to devote endless hours trying to keep up, while still getting work done that makes money for the business they're in.

I read through the article and it provided a lot of helpful information on the pitfalls with LLMs which, based on the title, is its intended purpose. I didn't take it as a shining recommendation for LangChain. If your point is that suggesting LangChain means they're not keeping up, as someone else stated, and because of that the other information is probably dated as well - that's far more helpful.

I wouldn't mind seeing a current guide on pitfalls and practical examples of interacting with LLMs with raw python - from someone who "has a clue".

There is no plastic in the fluid/material path of either machine - it's virtually all stainless steel and silicone. Basically the only plastic on them is in the switches/electrical parts where is is almost impossible to avoid.

I think the plastics we have noticed to be harmful are only the ones that are the most obviously biologically disruptive or carcinogenic. Not sure anyone building anything now can confidently say that the plastic they're using won't be a problem later on.

I'm also slightly skeptical of aluminum when in contact with acidic fluids but that's a whole different thing.

Hmm. Are you familiar enough with research in economics, or the hard sciences, to say that all the work in those disciplines lack an emphasis on “generalizable findings”?

It feels like epistemic weaksauce to claim that entire fields explicitly reject the goal of generalizable knowledge because they question or reject “the scientific method” on the basis of “I’ve read some case study / qualitative papers”.
Show HN: A more accurate email validation tool for catch-all domains
Hey HN,

I've been working on an email validation service that aims to provide more precise results, particularly for catch-all/accept-all domains, at a fraction of the usual cost. Traditional solutions often struggle with these edge cases, leading to more bounces, a drop in domain reputation, and overall deliverability issues.

Key points:

• Higher accuracy on catch-all domains: Our engine uses a combination of verification layers and heuristics to significantly improve accuracy.

• Cost-effective: Priced to be about 10X to 20X more affordable than many established competitors.

• Fast and scalable: Built for performance, so you can run large batches of validations without bottlenecks.

We're also launching on Product Hunt today: https://www.producthunt.com/posts/emailawesome. If you find it interesting, any feedback there would be helpful.

As a token of appreciation for your support, here's a coupon code for 1000 extra credits: NFFY5Agh6NVp6vP (valid until December 31, 2025), if you're the kind of heavy user who really wants to push the platform to its limits, just let me know and I'll hook you up with more credits.

> turn towards qualitative methods and epistemologies that are either misaligned with or explicitly reject the scientific method.

At least you can see their questionable method upfront, and can disagree with it.

Economics is worse: it has become completely quantitative, with sophisticated mathematics. I’ve heard the approach referred to as ‘physics envy’

It appears unapproachable to a non-expert and authoritative. But it’s not like physics

It’s conclusions are often catastrophically wrong because all the mathematics relies on shaky qualitative assumptions: people are perfectly rational, etc.

For example we have published economic research that forecasts that severe climate change will only damage global GDP by 1%.

They conclude that farming productivity will be reduced by 25% and farming is 4% of global GDP, so it’s 1%. Then they model some effect on the consumer because food prices go up.

It does not occur to the authors to model impact of physical result of that, which is, famine and political instability that comes with it.
I think this is just one "slice" of a full scan. The one in blue has a lot more detail, and less noise.
> > No easy answer is available, but it's worth asking.

> .. trying to dismiss the relevant discipline

Yeah. The question is worth asking yourself, your teachers, colleagues, and your friends.. but usually not worth asking (or answering!) strangers on the internet.

This type of “but what is it all for!” question has a huge asymmetry where it’s easy to ask and hard to answer, so it comes across as trolling. And if you’re talking to an adult individual who wants to argue not even about the priorities of basic research but the fundamental point of any of it, you can be pretty sure any conversation about the subject is pointless. People who want to take an anti intellectual stance aren’t waiting to hear a good argument before they change their point of view..

I’m finding so called “democracy” disappointing. Maybe we should reevaluate that certain domains should have an order and topology required by its purpose.

For instance, democracy has no place in formalized education. The student is the commodity and entered (and may exit) their arrangement of their own well informed consensual free will.

Beyond this, vigorous debate is nice. Democracy may be as base as appeal to mob appetite. Besides, aren’t democracies themselves contingent upon prosperity, peace, and well disseminated information (or something)? Which are we?

I'm not a big fan of productivity tips, but I often read about Parkinson's Law, and it works.

Not setting deadlines means a paused journey—small projects take too long and eventually feel stagnant.

The first time I read about Parkinson's Law, I set extremely strict deadlines, which didn't work. Later, I switched to flexible deadlines, and I started working with a relaxed mind. As a result, I always get things done before the deadline.

No data prep, no feature engineering: Predictive modeling in 2025 [video]
I'm not sure I know the use case for all of this logical complexity. Is there a specific use-case you had in mind?

Split the array of elements to process. Set up a promise.all against a function that handles sync/async function calls against each chunk and accumulates an array of results. This isn't the end of the world for any of the practical use cases I can think of. The efficiency loss and memory consumption is miniscule even across hundreds of thousands of records. This is as concurrent as anything else - the event loop is still a mandatory part of the processing loop. You can even defer every 1000 records to the event loop. Javascript is syncronous so there is no concurrency without threading. I can't think of an IO or non-IO function that would create the issues described of not yielding. We used to have chunks of 1000000+ records that would freeze the event loop. We solved this with structured yields to the event loop to allow other processes to continue without dropping TCP packets etc.

If the results are objects, you're not even bloating memory too much. 800KB for 100,000 records seems fine for any practical use case.

I like the idea of an async generator to prevent over-pre-calculating the result set before it's needed but I couldn't justify pivoting to a set of new functions called pipe, map, etc that require a few too many logical leaps for your typical ECMAScript developers to understand.

What's the win here? It must be for some abuse of Javascript that should be ported to WASM. Or some other use-case that I've somehow not seen yet.

This is also a reply to that deleted comment, because I had to type it all and also got to go outside and have my European 2 hour long lunch break while doing it.

If you have any kind of state in gen_server and the state or assumptions of it have changed, you need to write that code_change thingy that migrates the state both ways between two specific versions. If by some chance this function is bugged, then the process is killed (which is okay), so you need to nail down the supervision tree to make things restartable and also not get into restart loops. Remember writing database migrations for django or whatever ORM of the day? Now do that, but for memory structures you have.

Now, while the function is running it can't be updated of course, so you need gen_server to call you back from the outside of the module. If you like to save function references instead of saving process references in your state, you need to figure out which version you will be actually calling.

If you change the arity of your record, then the old record no longer matches your patterns.

Since updates are not atomic, you will have two versions of the code running at the same time, potentially sending messages that old/new stuff does not expect, and both old and new code should not bug out. And if they do bug out, you have been smart enough to figure out how to recover and actually test that.

Than there is this thing, if somehow something from the version V-2 still running after update to V-1 and you start updating to the latest V, then things happen.

You can deal with all that of course and erlang gives you tools and recipies to make it work. Sometimes you have to make it work, because restarting and losing state is not an option. Also it's probably fun to deal with complex things.

Or you could just do do the stupid thing that is good enough and let it crash and restart instead of figuring out ten different things that could go wrong. Or take a 15 minutes maintenance window while your users are all sleeping (yes, not everybody is doing critical infra that runs 24/7 like discord group with game memes). Or just do blue-green and sidestep it all completely.
