It's funny...I absolutely despise being advertised to, yet I find vintage ads fascinating. I don't know what that says about me.

I feel the same about a lot graffiti; if it's recent, it's an eyesore, but old graffiti can be extremely interesting. I guess both domains expose some elements of the zeitgeist seldom explored in other mediums. ¯\_(ツ)_/¯

Nice site, by the way!
Show HN: Cogeol – Align your projects Python versions by cog and endoflife.date
by szymonmaszke | 2025-06-30 16:01:38+00:00
Hello, cogeol is a small tool which allows you to manage Python versions of your projects (usually libraries) by utilizing cog's (https://github.com/nedbat/cog) static code generation and https://endoflife.date/ data.

For example - say you want to always support three latest latest Python versions, no more, no less (according to Scientific Python SPEC0: https://scientific-python.org/specs/spec-0000/). Currently that would be Python version 3.13, 3.12 and 3.11. When 3.14 officially drops, you would have to move your library manually to 3.14, 3.13, 3.12.

This is what cogeol automates, see the usage example: https://github.com/open-nudge/cogeol?tab=readme-ov-file#usag.... Also works with other files, see example in the README, thanks in advance!

If you want to follow for other projects, check out the opennudge GitHub here: https://github.com/open-nudge (or associated links at the top)

What do you mean, "let them in"?

Up until 2024 there were no restrictions on cheap Chinese EVs that didn't apply to any other car. The cheap ~$10k Chinese EVs simply don't meet US safety standards.

There have been Chinese-built EVs sold in the US: https://www.polestar-forum.com/attachments/1000009812-jpg.27...
Ask HN: When will YC do a batch in Europe and/or Asia?
by HSO | 2025-06-30 16:02:39+00:00
In light of recent developments that I think most people will be sufficiently aware of, no need to rehash here, wouldn´t this be the time to do batches in Europe and/or Asia?

I would imagine the YC network is both large and international enough that you have the people who could mentor locally.

Speaking strictly for myself, while I still find the program very attractive, I am not willing to risk bureaucratic border nightmares, Salvadorean dungeons, or other harassments for it.

While I wish Europe or Asia had more direct competitors offering similar terms like YC, it is what it is and so, are you going to do it? If so, when? If not, why not?

Obv this is just a suggestion, but I think it would be good for YC too because for sure Europe and Asia are going to build their own ecosystems and internet economies with new motivation/urgency now so this would be good for everybody.

I don't always make 6502(ish) errors, but when i do, it's usually the memory address instead of the immediate! It's a very common and easy mistake to make, and i believe Chuck Peddle himself deeply regretted the (number symbol, pound sign, hashtag) #$1234 syntax for immediate values. I made # appear bright red in my IDE, it helps, a bit... Even the ASM gods at Rare fell victim to the same issue!

I find any claim that superintelligence helps with physics to be a hoot.

Dark matter is the most notable contradiction in physics today, where there is a complete mismatch between the physics we see in the lab, in the solar system, and globular clusters and the physics we see at the galactic scale. Contrast that to Newton's unified treatment of gravity on Earth and the Solar System.

There is no lack of darkon candidates or MOND ideas [1] what is lacking is an experiment or observation that can confirm one or the other. Similarly, a 1000x bigger TeraKamiokande or GigaKATRIN could constrain proton decay or put some precision on the neutrino mass but both of these are basically blue-collar problems.

[1] I used to like MOND but the more I've looked at it the more I've adopted the mainstream view of "this dark matter has a galaxy in it" as opposed to "this galaxy has dark matter in it". MOND fever is driven by a revisionist history where dark matter was discovered by Vera Rubin, not Zwicky [2] and that privileges galactic rotation curves (which MOND does great at) over many other kinds of evidence for DM.

[2] ... which I'd love to believe since Rubin did her work at my Uni!

Chronic Trigger had one like this. I recall there is a section where you catch a rat and have to input four simultaneous key inputs after catching the rat. But usb inputs only forwarded 3 at a time so to get passed this you’d mash all four and eventually you’d get them registered inside the very short timeframe. Took many tries and was very frustrating.

> one that will quickly be left without any enterprise

I would be fine with a small town lacking any chain restaurants or big box stores. Imagine that, small business owners could do commerce with each other and not have to have 7-figure sums as barriers of entry?

> or have the police stop responding (an open invite for consequence-free theft)

That's the point: a covert way for people to take back the power even if there is a foot-thick stack of UCC and other bullshit laws preventing them from fucking with Daddy Bezos. The business would have to shut down because it would be de-facto legal to steal from it.

Sorry you like simping for megacorps, but as the UHC shooting shows, people who have had every ounce of power stripped from them will find other means to be heard.

More than you'd think.

My honest opinion, as a person who has gigged a lot for money, who has played a whole lot with folks who are now in their 70s and 80s, and who has retired from programming into a life where I can afford to just make music with folks is this:

a lot of folks on this thread have very little understanding of how the music industry has ever operated and almost no understanding of the material and historical situation of musicians working in the 20th C.

There is a whole technological progression proceeding backwards from streaming to the Clear Channel consolidation, to the rise of cheap DJ equipment going back at least as far as the the rise of mass sheet music production, and that procession has changed the music industry at every step.

While it's not some universally transcendent material praxis, there was indeed a time between the 1940s and the late 1990s when the market was much wider and more distributed in ways that made it possible for a pretty wide and diverse set of folks who aren't A-list national acts to develop functional careers as musicians.

If you're not aware of that situation, perhaps you don't have enough of a basis in the history of that industry to be commenting with the kind of certainty you're displaying.

I played a lot of bionic commando as a kid. When I loaded it up in an emulator in the early 2000's it was way harder than I rememberd. Then I realized there was an emulation bug where the enemies didn't disappear when you blew up the base, but Ladd still froze; that meant I needed roughly 2 extra life points when clearing a level. Just to see if I could, I did beat it that way once, but never again.

Apple does their own language model development and worst case could host eg Qwen or Deepseek. That would be an absolutely insane waste of cash.

Their problem isn't inability to develop or lack of access to technology, they're extremely good at that, They're like a vertically integrated combination of Microsoft and Nvidia.

Their problem is the lack of vision and inability to productise what they develop. IE their problem is that they're Apple, buying other companies won't change that.

> Yes, they should.

So you accept that better driving training would be better.

> If you find out a way to retrain everyone on the road more cost-effectively than a $30 backup camera, do implement it. (Don't forget figuring out how to get people to maintain those skills.)

As time goes on, older people stop driving either they stop driving (they realise they are too old to drive) or they die.

If you implement better driver training. Then newer driver have to do that training. So over the overall minimum standard improves.

A $30 camera is something that doesn't improve the overall minimum driving standard. It is a band-aid over a bigger problem.

> Until then, I'm glad my car has some safety features that protect me when I get rear-ended in stopped traffic by someone who wasn't paying attention.

Crumple zones have been standard in cars for like 30 years now. That rear camera isn't going to help you.
Reading problems aren't a willpower issue – your brain got rewired
by ccarnino | 2025-06-30 16:05:17+00:00
A few years ago, I was reading 15+ books a year. Last year? Maybe one or two that I actually finished.

For the longest time, I blamed myself. Lack of discipline, poor time management, whatever. But then I started noticing the pattern wasn't just me - friends who used to devour books were struggling with the same thing. Smart people, curious people, people who wanted to read.

The turning point came when I realized I could binge-watch a 3-hour YouTube deep-dive on Byzantine history without losing focus, but couldn't get through two pages of a book on the same topic. That's when it clicked - this isn't about willpower or intelligence. Our brains literally got rewired.

Think about it: we've trained ourselves on TikTok, Twitter, Reddit - constant stimulation, instant feedback, bite-sized content. Then we try to sit down with a book that demands sustained attention for hours, and wonder why we're re-reading the same paragraph five times.

I tried everything to get back into reading: audiobooks (mind wanders after a minute), AI summaries (forgettable), author interviews on YouTube (actually pretty good, but limited). Nothing stuck until I stumbled on something that worked.

Six months ago, I started uploading books to ChatGPT and prompting it to teach me through conversation - asking questions, giving examples, making me explain concepts back. Instead of fighting my shortened attention span, I worked with it. Suddenly I was spending an hour a day learning from books that had been gathering digital dust for years.

The technique is simple: turn passive reading into active dialogue. Instead of trying to force yourself through dense text, have the AI break it down, quiz you, give you analogies. It matches how our brains want to consume information now.

You can set this up yourself with ChatGPT, or there are tools that automate it (I ended up building one at https://thinktotem.com for myself because I was doing this so much). The point isn't the specific method - it's accepting that our brains changed and adapting rather than fighting it.

I'm back to learning from books I thought were impossible - Dante's Divine Comedy, The Art of War, dense philosophy texts. Not because I got more disciplined, but because I stopped trying to read like it's 1995.

Anyone else notice this shift in their reading ability? Curious what solutions others have found.

Dedicated servers were mainly removed to balance matches with matchmaking IMO.

How do you do proper matchmaking with user-hosted dedicated servers?

Like what would an end-user dedicated server system look like for call of duty warzone, or Fortnite, battle royale games. A round lasts about 20 minutes and you want 150 players filled in right at the start and you don't want to wait more than a couple minutes to fill the server for each round.

The other popular types of FPS games are mostly like 5v5 modes, and you want really balanced teams based on an MMR system. I don't really see how you do that with dedicated servers.

I just paid about $12K to install mini-split heat pumps on a main house and ADU.

Two separate systems.

That's about 1/2 of the "minimum" cited above, and it's for 2 buildings.

This is so similar to the EV panic.

I'm not sure if the article is LLM slop, I only scanned it. But I agree with the main point that it's not the tech holding this back, it's the US population.

I also bought a 2 year old used Nissan Leaf (w/ 15K miles) for $15K. I charge it at home.

Neither of these purchases broke the bank. And both of them will pay for themselves over a few years. Maybe American's should learn to multiply. Then the cost of something over time will make it's adoption a clear winner.

The resistance to electrification is one of the US's biggest self inflicted wounds (after actual gunshot wounds of course).

> Data is being limited though, like not sending opponent location data unless the client can see them

So far as AAA games go this is pretty rare in practice. I guess there could be some problems to solve, e.g. you'd need to be conservative because a player could appear around a corner between server ticks, or the fact that RTS games usually operate by running a shared simulation[1].

Yesterday, I went into Best Buy with a friend to look at soundbars. As we were looking, a young man came up and said "Do you have any questions?" - I said we were just browsing, and he smiled and that was that.

He came back a few minutes later when he saw me scanning a QR code on the price tag. Odd since I signaled I didn't need anything. He asked again, "Anything you need help with?" - This time I was still wishy-washy but said "Yeah, I'm checking the inputs on this soundbar to see if it has 3.5mm and how many HDMI ports it has".

And without asking any more details, he smiled and said "Alright!" and walked away. We were completely baffled.

A PnP placing the components upside down onto a surface printed by another head would be interesting. You could align the heights of the resting surfaces to optimise pads needing to be connected being on the same plane. I'd still want to lay copper but if you had the ability to squirt a little solder paste from (yet another) head, you could stack everything with wire connections into a very 3d circuit.

If the base material was thermally conductive you could have a heatsink block with the circuit embedded in it.

> However, entry-level opportunities have taken a significant hit, dropping by nearly a third since the advent of widely available generative AI tools at the end of 2022.

As others have pointed out, we're off the back of COVID and money is tight. Most companies are looking to shrink team sizes, hence the lack of hiring. AI tools have almost zero relevance, and the rest of the article does not substantiate the claim at all.

> Despite this, year-on-year growth remained positive at +0.49%, marking the third consecutive month of annual improvement and suggesting a slow but steady recovery from the recent market slump.

There are things that can be done to screw with numbers, but it only works for a short time. The UK for example only counts unemployment as those actively looking for work, but it is well known that there is a growing number of permanently unemployed which is hidden. The number of people applying for PIP (a type of disability allowance typically awarded to those unable to work) is growing by 1k a day [0]. In perspective, the population of the UK grows by ~1.6k a day and is projected to fall.

The growth figure is likely based on the ONS [1], which are constantly having to revise their figures for data that was already available at the time of publication [2] - they do this a lot. One hack by this government is when they grew the public sector at the cost of the private sector, which is unsustainable. A company I know halved their employees but still pay the same amount of national insurance, so the economic value per employee is reduced due to increased overheads.

This is not unique to the UK, though. I speak to many Europeans that go through a similar situation, and I hear of similar stories throughout the West. The EU for example has a growing issue with ECB bond management where it plays games to to try to bring down borrowing costs. The Japanese market, a large purchaser of foreign debt, is starting to get concerned [2], and signals a potential crisis for the US to be able to borrow at low rates. From all accounts China is just about keeping their head above the water and are pulling a lot of tricks.

There is a huge difference.

If I am running a factory that use to create carriages and now creates cars, I need people who can create cars now. If I want to expand the number of customers I serve, I need to hire more people.

If I am a software company, I don’t need to scale the number of software engineers I hire to serve more customers.

Since gen AI has been a thing, I mostly pivoted to more strategy based cloud consulting than hands on keyboard software development. But before Gen AI, I would have needed a couple of junior developers to do the grunt work of implementing well defined implementations. Now I can do both the strategy and implementations in the same amount of time.

Even before Gen AI the entire reason that software engineers get paid so much because software development has high fixed costs but near zero marginal costs. No other industry has been like that historically.

I don't think there is anything interesting that we disagree on. I'm just not finding the ontology that I must accept/adopt to do quantum mechanics objectionable despite that it shows little respect for my scale-laden experiences. I find that superpositions, non-local couplings, etc. Do not mix well with coarse grained macrostates, or any sort of experience I have had at scale. This is probably because the entirety of my experience is rationalization after the fact of reality, constructed in my brain for the purpose of maximizing gene replication. But I am trained to deal with paradigm change -- incomensurability, ontology, and epistemology are part and parcel of that endeavour.

In QM, I don't even get the comfort of assuming there is an objective reality filled with entities that enjoy continuous existence in time.

I definitely read less than I used to. I think in the past some books didn't need to be the length they are. I still like narrative non-fiction and for those the level of detail is the point.

It is harder to get back into reading, but think if you force yourself a little at first your brain gets "rewired" back to it just fine.

> at least in the case of a manual gearbox

Ok, let's say you go stupid simple for the transmission and have a super basic classic four-speed manual.

Right off the bat, you've got clutch wear. In that e-CVT, there are no sliding clutches. Everything is connected all the time. Immediately, we see a wear component that will eventually need replacing. Not might need replacing, will need replacing. It is a consumable part, designed to wear.

You now have cable assemblies which will eventually stretch over the life of the car. Those will eventually need adjustment. Once again, these just don't exist at all with the e-CVT system.

Now you have a shifter and gear selector. This will need to slip in and out of other gears. Often this is not a perfect shift, imparting wear on the transmission components. Once again, you don't have a gear selector in an e-CVT, this wear never happens. This wear can cause premature failure of the transmission. This is largely controlled by the skill of the operator, sure.

Just a few quick examples. But this is then also an incredibly basic manual transmission, you won't find such a thing on pretty much any recent mass market car. These days you'll see complicated automatics with servos and what not to control the gear ratios, massively more gear ratios, rely on fluid channels to push things around inside, rely on computers to operate them effectively, etc.

And as Retric mentioned, there are analoges for most of the hybrid components in a pure-ICE car. You already have a DC motor set to drive the car in the starter motor. You already have an inverter, the alternator. You're not really adding a ton of new things, you're just massively upsizing some of the things you already have and massively simplifying a lot of the other components.
by enragedcacti | 2025-06-30 16:08:01+00:00
you and Retric are using different definitions of "series". A "series hybrid" is a specific term describing a design that uses an ICE engine to generate electricity that powers an electric motor. This design replaces the transmission completely because the ICE rpm doesn't need to be matched to the wheel speed and the electric motor has a much wider RPM range.

Many series hybrids do have a way to power the wheels directly with the engine at highway speeds but it's generally much simpler than a full transmission. Most Honda hybrids for instance have a single clutch that connects the ICE to a "6th" gear.

> You keep bringing up transmissions when the main point is related to the ICE.

less parts -> more reliability
by Retric | 2025-06-30 16:08:15+00:00
> all the ICE/electric interfaces are more reliable than a traditional transmission

The argument goes like this,

ICE cars have an alternator (electric motor 1), starter (electric motor 2), battery, and transmission. A beefier alternator (generator) + starter (electric motor driving the car) + battery adds less complexity than a transmission. That’s the simplest EV design where the engine only ever charges the battery. It’s perfectly viable for a long range plug in hybrid that only ever uses the engine on long trips.

The downside is batteries have conversion losses, so most hybrids have various ways of directly using engine power which then adds complexity. But ultimately hybrids are more complicated than EV’s but very much can be simpler than modern ICE cars.

PS: Technically some old ICE designs like dynastart used to do the same as hybrids where the same electric motor acted as a starter and alternator but in modern ICE vehicles the tradeoff around now little time the starter is needed and how little power the alternator needs to generate means it’s more efficient to separate it out. http://www.isettadoc.com/files/dynastart.pdf

> So you accept that better driving training would be better.

Oh, certainly! But it needn't be exclusive. (And "teach people better" is a lot harder than running a wire to a $30 camera.)

> As time goes on, older people stop driving either they stop driving (they realise they are too old to drive) or they.

They drive far, far too long on average. I'd love to see an annual requirement to pass a driving test over 60, but… old people vote.

> A $30 camera is something that doesn't improve the overall minimum driving standard.

Sure. It improves the "backing up" bit only.

> Crumple zones have been standard in cars for like 30 years now. That rear camera isn't going to help you.

Both are safety mitigations, for different aspects of driving.

I'm glad I can both survive a rear-end crash and being reversed over by someone driving a Hummer with a six foot high blind spot in the back. I don't have to pick one improvement, which is great.
