> It does not require manufacturers to pre-install them, and it does not use the electronics built into the car. It sounds analogous to the breathalyzer devices that are an option for judges in some jurisdictions.

There's already a law on the books requiring breathalyzers in all new cars by next year: https://live959.com/law-mandates-mass-cars-to-have-breathaly...

Presumably, anti-speeding tech will be made mandatory by the same incremental approach in time.

We speak of the Wild West as “lawless”. I assure you there were very much laws against murder and theft then. They just had sporadic enforcement. Much as roads and highways are in many parts of the country. In California I see racing, 100mph driving, weaving like mad. In the ride home from the airport I watched teenagers race and crash. Drunk driving all over wine country. Never once saw anyone like this pulled over.

Probably having the license AGPL or some certain restriction where you can only attract the big business users on this product.

Let's be honest, you can make money from the small guys but they are little cents as compared to giving corps self hosting guides / licenses like docker..., I know they may not come under pure open source, but the question is tricky, and so is the answer.

So this becomes "fair source" I guess.

I just want the code itself to be readable & buildable from scratch, I want to trust in the process that there are atleast some person who have searched this code and found no malicious use. I want it so that I can modify your program if I really want to, maybe even redistribute that modifications.

Now that I started looking for it, I think it was Repton because I remember buildings.

I think the crack protection was pretty clever - it let you play a couple seconds of the game to get a taste of it. If I had the means I would have bought it, but I was a poor 14 year old

I am the first to admit that the UI does not make sense to people who have not seen it in use. I have done some user onboarding sessions where you just “let them ask questions and click” and it goes terribly if it’s any consolation, I have never gotten that feedback after showing people how to use it (quite the opposite actually!)

Wrt to the expression, all expressions created today succeeded, so if you’re still seeing a progress bar let me know as that’s a bug. It’s possible something failed with the live updates, or it does take several minutes to create an expression (depending on servers, it can take up to 10 minutes at times, although the typical timing is 2-4 minutes depending on the expression)

If you click on any of the review methodologies, it will start reviewing any of your successful expression. From there, the experience should be a lot more explorer-friendly :)

What it’s doing is: analyzing the sentence, splitting it into phrases, aligning it across all languages, tagging all of the gender/case/tense/etc, researching pronunciation, generating audio, aligning the audio, prioritizing the words (across several axes), and generation explanations/dictionary for each individual word

This is a relative matter. The autobahn, without speed limits, is safer than US high ways with speed limits. The speed limit being suggested there is also a higher speed than the speeds reached on most US highways, which were a clone of the autobahn. Research into this matter has long suggested that there is an optimal limit at the 85th percentile and setting a speed limit above or below it harms safety. The autobahn demonstrates the optimal limit is well above the limits that are used in the U.S., which coincidentally are well below the 85th percentile.

>“A significant association was found between all reasons for DWVL and the risk of causing a road crash. This association was particularly high for drivers with a suspended license and drivers who had never obtained a license. In these subgroups of drivers, the proportion of the relationship explained by high-risk driving behaviors is high” [1].

"Among church attendees, those attending church services in a prison were more likely to be convicted of a crime in the future than the average"

I too can mislead with sampling bias.

Nobody with a double digit number of brain cells is going to be impressed that a group that includes a lot of people who lost their licenses is going to be more crashy than the average. The average has a lot more people in it to water down the statistical effect of those people. But that doesn't mean that a lot of people in your "bad" group are actually bad on an individual level rather than a statistical one.

Pretty much every license suspension is for financial reasons at the end of the day because people who can afford lawyers and fines and whatnot are much more able to avoid the suspensions.

A synchronous interconnect provides not just a source of truth but also stabilizes your grid frequency. If you have an isolated grid you have to match generation to demand to keep the grid frequency stable. If you have a 1GW interconnect that means you can mismatch generation and demand by up to a gigawatt and still be fine. I imagine that makes for a much faster startup procedure

EdTech is a cool “idea” but most people don’t want to learn. It doesn’t scale imo, and it’s better to do it as charity for people in dire poverty who want a way out (no money in that).

For those better off than that, I’d rather sell them stuff or keep them engaged than try to get them to think/become smarter because honestly and brutally speaking, nobody is going to pay for that.

For 99% of people… As long as they have basic literacy and can make some money, they will want to spend that money on entertainment and other time waste activities.

Those who want to be smarter will find a way, without needing some cool education platform.

MAGiE: Your MAGnetic Interactive Explorer

A simple puzzle game: a cassette-futuristic story, heavily inspired by Nell’s adventures at Castle Turing in Neal Stephenson’s “The Diamond Age”.

I could go on and on...

I’d love your feedback:

Rewind to the start of the story: https://magiegame.com/test/2025/04/04

Right now I’m focused on story development and integrating it with the daily-puzzle system I built last time I was between jobs.

This is a years-long slow-burn side project. My career moved away from the frontend long ago—this is my first React app, with a Django backend running on AWS Lightsail.

> optimizing diet and rigorous exercise comes at some cost in the form of time spent in your precious youth. so you sacrifice youthtime for a chance at a longer better old age. each hour of exercise does not make you live an hour longer, so you are net negative from the get-go.

Pretty much all science on exercise's impact on both physical and health can be loosely summarized by "doing anything, anything at all is likely to have significant short and long term benefits". Similarly, nutrition can be summarised as "try eat a balanced diet, but at the very least just avoid hyper UPF, and don't eat red meat every day". You might decide that's worth it, but "walk your kids/dog/partner/self twice a day and only eat red meat on the weekends" is probably enough to make a significant impact for a very significant number of people.

The wild west is as equally misunderstood. There were far far fewer guns carried by people then compared to now and laws were well enforced even in sporadically populated areas. The exceptions were boom towns, like gold rushes, where the populations grew faster than norms could be established.

I guess if you don't see it then it must never happen to anybody ever. That isn't valid data.

This ended up being fake news:

Justice Department attorneys argued that it was in the child's best interest to remain in her mother's legal custody and suggested the child could return, writing, "V.M.L. is not prohibited from entering the United States." Trump administration officials told the court that the mother had informed ICE agents that she wanted to bring V.M.L. with her to Honduras, providing a handwritten note in Spanish that they said confirmed her wishes.

> but I thought they were incredibly hardened, with backups and contingencies in depth

Some are harder than others, and some have random flaws which nobody can really predict.

Spain seems in the transition to renewables, so it's possible that they have some flaws because they are still in the process, or because it's something which never happened before and is unknown territory. Also, Spain had some economic problems in the last decade, maybe someone build to cheap or was even cheating somewhere.

> Are the grids at this scale really this brittle? Would there be a death toll from this?

Hospitals should have backup-systems. Traffic should be able to stop in time. I guess the most problematic parts are people stuck in elevators and other spaces which only open electrical, as also the loss of cellular phone-connections for calling helpers.

As an obvious and specific source of examples, all the features they decided to omit, "optimizations" they considered but rejected for various reasons, etc. are not present in the code and seldom in the comments or documentation.

Occasionally you will see things like "Full search rather than early exit on match to prevent timing attacks" or "We don't write it in format xyz because of patent issues" or some such, but the vast majority of such cases pass unremarked.

I'm not sure I really understand the question -- it seems like it's just asking "would you ever host a discussion board". Am I understanding correctly?

If I were to entertain standing up a board like HN, I wouldn't use something like Lemmy to do it. I'm not sure what benefit I'd get from that. HN is pretty basic and, in my opinion, that's an important part of the appeal.

The difficulty is still the same: for each piece of the puzzle (substations, high voltage power lines, transformers, generators, loads), they have to wait until enough power is available at the connection point, and carefully manage the power balance so it's neither too much nor too little (and if they get it wrong, things trip offline and they have to start all over), while the grid is in a degraded state (often meaning no alternative paths, so a single fault can set them back several steps). The only difference being that the black start "generators" are these still working international links (which could be very far from the important parts of the national grid).

It might be faster to instead black start several independent power islands in parallel, and connect them together as a final step. At least in my country (Brazil), that's how it's done for large-scale blackouts, even when some of the country still has power; it was done that way for the partial blackout in 2023, and there's a written procedure on how to do it (which is available on the operator website, if you know where to look). In 2023, some areas failed to black start for one reason or another, and had to wait for power from the outside; other areas managed to black start as expected, and were then synchronized with other areas until everything came back together.

> In fact I hear people telling me they understood the blog _better_. The whole academic writing shtick has become so obtuse that not only writing is cumbersome, but so is reading.

Legible writing has little incentive. You can write in a simple down-to-earth manner and risk having someone objecting "Your work is isomorphic to X, done years ago." Your counter-objection, "Well, X is so incomprehensible that no one had any chance of understanding it", will fall flat. Better not risk it, write in an obtuse form and withhold the source code.

That's a difficult question to answer because I don't know if I'll grow the extension in the future. Only time will tell.

After I completed the extension I did try on another model and despite me instructing it to generate a v3 manifest extension, the second attempt didn't start with declarativeNetRequest and used the older APIs until I made a refinement. And this isn't even a big project really where poor architecture would cause debt.

Vibe coding can lead to technical debt, especially if you don't have the skills to recognize that debt in the code being generated.

This is great, but the need for a long glossary of terms is a sign that you might want to keep tuning language/word-choice.

As you've seen in replies here already, many term choices you've made have enough variety in how they're conventionally used that people incorrectly assume they know what it means only to see the "nope!" popup when they try to apply it. That frustration is going to spoil first impressions of what actually seems to be a really great puzzle system, which is a shame. The more you can reduce that experience, the less likely you'll be to prematurely burn off players.

A good measure for getting it right would be that you don't even need a glossary at all, or that you can get it so condensed that you can make it more prominent without becoming distracting.

Alternately, you could maybe use symbols instead of words to represent your rules, as more players would intuit that they should learn the symbols before making (wrong) assumptions.

I appreciate this, but also wonder if we are in the middle of a transformation where some forms of creativity (note: not necessarily engineering) are being "flattened". Everyone can output beautiful pixels, beautiful audio, beautiful token sequences.

Maybe it's like the transformation of local-to-global that traveling musicians felt in the early 1900s: now what they do can be experienced for free, over the radio waves, by anyone with a radio.

YouTube showed us that video needn't be produced only by those with $10M+ budgets. But we still appreciate Hollywood.

There are new possibilities in this transformation, where we need to adapt. But there are also existing constraints that don't just disappear.

To me, the "Why" is that people want positive experiences. If the only way to get them is to pay experts, then they will. But if they have alternatives, that's fine too.

Sounds like keycloak can sort of allow some sort of decentralized option or have many and I mean many including the matrix sign in as a option.

Keycloak also has strong integration in a lot of languages, there are other projects like authelia etc. but for some reason keycloak actually seems to me of having a little bad ui but still absolutely great in what it does

But authelia/ authentik are easier to host/integrate IDK

>review 50 PRs a day, everyday

Basically my job as a staff these days, though not quite that number. I try to pair with those junior to me on some dicey parts of their code at least once a week to get some solid coding time in, and I try to do grunt work that others are not going to get to that can apply leverage to the overall productivity of the organization as a whole.

Implementing complicated sub-systems or features entire from scratch by myself though? Feels like those days are long gone for me. I might get a prototype or sketch out and have someone else implement it, but that's about it.

Working on designing and building an interface to properly integrate a modern phone with Toyota/Lexus infotainment systems from before 2010 (which are using the proprietary AVC-LAN protocol).

I've explored all existing commercially available solutions and none match my requirements/standards (high-quality audio codec/DAC, USB-PD, steering wheel controls, no splicing or cutting into the loom, no cutting up the dash, etc.).

After researching how the Toyota/Lexus infotainment systems work I found they are highly modular, and actually quite easy to produce custom modules for. The proprietary AVC-LAN protocol is well-understood, and actually makes it really easy to integrate with. The display are just NTSC composite, and touch events (in fact, all button presses, including steering wheel media controls) are emitted on the AVC-LAN bus.

An simple board with some interfacing logic, a DAC and an RPi nano should be all I need to allow good Bluetooth audio integration, and lossless audio via wired USB, both controllable from the steering wheel. You could do all sorts of fun things with the display (such as displaying vehicle status from ODB, lap timer, G-force meter etc.). If I use a RPi compute module then running Android Auto should be quite feasible.

It's just a hobby project though, I'll probably open-source everything. Not planning on commercializing it.

I agree, likely the first immortal person has already been born. Perhaps even large swaths of the population are already effectively immortal, but they just don't know it yet.

Sadly, my main fear is that immortality will only be available to the extremely rich and powerful. Generally historical progress is made when the old guard die, be it in science with the leaders clamoring to old theories, dictatorships falling when their leader does, companies setting a new course when their founder/CEO retires.

I shudder at the thought of living in a world where everyone still dies like before, except an entrenched immortal powerful elite.

Yes, but it's more than that. As I've written before, LLMs (and all AI) lack intentionality. They do not possess concepts. They only possess, at best, conventional physical elements of signs whose meaning, and in fact identity as signs, are entirely subjective and observer relative, belonging only to the human user who interprets these signs. It's a bit like a book: the streaks of pigmentation on cellulose have no intrinsic meaning apart from being streaks of pigmentation on cellulose. They possess none of the conceptual content we associate with books. All of the meaning comes from the reader who must first treat these marks on paper as signs, and then interpret these signs accordingly. That's what the meaning of "reading" entails: the interpretation of symbols, which is to say, the assignment of meanings to symbols.

Formal languages are the same, and all physical machines typically contain are some kind of physical state that can be changed in ways established by convention that align with interpretation. LLMs, from a computational perspective, are just a particular application. They do not introduce a new phenomenon into the world.

So in that sense, of course LLMs cannot build theories strictly speaking, but they can perhaps rearrange symbols in a manner consistent with their training that might aid human users.

To make it more explicit: can LLMs/AI be powerful practically? Sure. But practicality is not identity. And even if an LLM can produce desired effects, the aim of theory in its strictest sense is understanding on the part of the person practicing it. Even if LLMs could understand and practice theory, unless they were used to aid us in our understanding of the world, who cares? I want to understand reality!

I can appreciate the ability to revert to hand cranking an air compressor, yet I can't help but feel that the 99.99% of events, you'd be better served with keeping a two stroke gas engine ready to go. Air compressors tend to have parts just as or more vulnerable to environmental factors, and you get a lot more power for less elbow grease out of a two stroke.

The graphs around programming language & use cases makes sense from my personal usage. What's interesting is that they call out "automation" vs "augmentation", but also mention "directive" vs "feedback loop" for both claude code and claude ai - directive in this case being similar to solving a problem without iteration while feedback loop is the human iterating with an agent.

I think for the near future we're going to continue seeing feedback loop be the primary way we interact with coding agents simply because we generally don't specify all coding tasks with no ambiguity. If we did, then we'd already have some pseudo code that the agent could just directly translate into working code / validate with testing.

> If a significant percentage of vehicles are deemed unsafe to drive because of this, then removing them from the road would be a good thing.

“Good” is not a binary state, and it’s also wildly subjective. If by removing 100,000 unsafe cars from the road, you prevented 10,000 vehicle collisions, but 20,000 people became impoverished, is that good? It depends on your point of view. New York State, being largely dominated by NYC, I assume has an above-average social safety net. Perhaps they really are able to have these stricter requirements, while also ensuring that the negative impact felt on their citizens is minimized. Mississippi neither has that nor wants it. Were they to implement strict vehicle safety standards, the ripple effects would be much larger than those felt by a state with a stronger desire (and the budget) to care for their citizens.

Re: sources, can you post some? I’m not trying to Sealion you here, but I have no idea what specific studies you’re thinking of, and I would prefer to be on equal footing.
