America doesn't have a clear "Antagonist" anymore to unify media, news, and discussion in an "us vs them" way. Instead lots of groups have found and formed their own bad guys and media is largely fractured on that parameter.

This is why lots of boomers think the news is "biased" now too, because they grew up with all of society unified against a common EXTERNAL foe, for better or worse. There was nobody saying "actually the USSR shouldn't be the enemy", mostly because socialist everything was snuffed out by WW2.

Why does the slippery slope concept surprise you? It actually happens often - banning smoking indoors, for example - started in just one city, once they tweaked the model and overcame the legal challenges, it spread rather quickly. Legalized casinos, same thing. Uber, drinking age, pot legalization, more. Why would toll roads or congestion pricing be different? (Idaho's Sun Valley probably already implements something similar). And ICE vehicles are definitely in many politicians' crosshairs, if you don't already see that coming in the next decade, you aren't really looking.

I'm stuck on the latest gitea (1.22) that still supports migration to forgejo and unsure where to go next. So I've been following both projects (somewhat lazily), and it seems to me that gitea has the edge on feature development.

Forgejo promised — but is yet to deliver any — interesting features like federation; meanwhile the real features they've been shipping are cosmetic changes like being able to set pronouns in your profile (and then another 10 commits to improve that...)

If you judge by very superficial metrics like commit counts, forgejo's count is heavily inflated by merges (which gitea development process doesn't use, preferring rebase), and frequent dependency upgragdes. When you remove that, the remaining commits represent maybe half of gitea's development activity.

So I expect to observe both for another year before deciding on where to upgragde. They're too similar at the moment.

FWIW, one of gitea larger users — Blender — continues to use and sponsor gitea and has no plans to switch AFAIK.

There is a very well researched youtube video that explains a couple of these things:

https://www.youtube.com/watch?v=FrUWoywZRt8

I do not recall where I heard about the helium-3 situation, but I recall hearing some figures and the prospect of having enough to run fusion reactors was not good. Doing a search suggests that I had been only slightly mislead about the scarcity of helium-3. It is still extremely rare, but the US reportedly has used up to 70,000 liters of it per year:

https://en.wikipedia.org/wiki/Helium-3#Human_production

The density of Helium-3 at STP is presumably 0.1338 g/L, based on Helium-4's 0.1784 g/L. That suggests that the total annual US industrial demand is ~9 kg. This is definitely not as bad as I had thought, but it is still fairly dire.

As per wikipedia, a single 1GW nuclear fusion reactor that is 100% efficient at converting helium-3 into electricity would need 52.5 kilograms per year. 6.7 metric tons per year would be needed to power the entire US.

https://en.wikipedia.org/wiki/Helium-3

That assumes 100% efficiency, and if the conversion efficiency is anything like a nuclear fission plant, we would be lucky to see 3% efficiency, but we could be optimistic and assume something higher. Either way, it does not change the conclusion.

With an annual supply of ~9 kg, practical helium-3 fueled nuclear fusion reactors are not happening. Maybe the supply would be higher if you include other countries, and maybe we could get it somewhat higher if we try, but the reality is that helium-3 is an extremely rare isotope and the idea of using it as a practical fuel for a nuclear fusion reactor is a pipe dream unless the supply problem is solved and people figure out how to actually build a reactor that generates power using it, without encountering any of the other known problems that make this unlikely.

The difficulty in scaling supply is why are people discussing wild ideas like mining the moon, or even mining Jupiter. The supply situation is so constrained that the US government is reportedly buying 3 liters of it from a company that promises that it will strip-mine the surface of the moon for it with delivery by April 2029:

https://www.morningstar.com/news/pr-newswire/20250507sf81778...

I fully expect them to fail to deliver.

That said, the fairy dust remark was probably inaccurate, but the idea that our supply is short by orders of magnitude is correct according to mathematics.

This is super neat.

I built a game[0] along similar lines, inspired by infinite craft[1].

The idea is that you combine (or subtract) “elements” until you find the goal element.

I’ve had a lot of fun with it, but it often hits the same generated element. Maybe I should update it to use the second (third, etc.) choice, similar to your tool.

I watched The Melancholy of Haruhi Suzumiya recently. The main character can bend reality to her wishes. She is unaware of this. But it makes her basically a monster, because the other characters are locked in a constant struggle to prevent her from getting bored or angry, in case she remakes the world without them in it. By the end of the series this is not resolved at all, she is still a monster with the other characters in her thrall, it's just that the last episode is somewhat calmer as if they've arrived at a kind of stability. Also there's eight episodes in the middle that are all nearly identical, because they get stuck in a time loop due to her unwillingness to permit the end of summer.

I wouldn't build national strategic dependencies without more control over the supply chain if I could avoid it, but that said, the article has zero evidence this is nefarious and is light on detail.

Lots of things have diagnostic additions which make little or no sense out of context. If the units include equipment meant for deployment in rural and remote China, having multiple comms modalities would be net beneficial.

all modern high end vehicles now come with the risk of a low bandwidth feed on all the time. A friend was told to drive to a garage because they remote detected issues in lubrication before he got an in car diagnostic message.

Take the equipment out of context, that comms feature might be built in even if not requested.

Fermilab would disagree with you on the quenching problem:

https://lss.fnal.gov/archive/2023/slides/fermilab-slides-23-...

As for the amount of radioactive material, the experimental reactors are several times the size of fission reactors. It is obvious that they irradiate far more material.

Sounds like very straightforward tax evasion. The business brings in lots of cash, doesn't pay taxes, obscures the books enough so that there's no smoking gun. Some of the people participating in the scheme are skimming, but maybe less than the taxes would be, or maybe the owners are also implicated and would face criminal penalties themselves, so it's better for everyone just to keep it going and keep the books messy. Don't need mafiosos from TV for that.

I doubt rust guarantees that “Put something after v on the heap” behavior.

The whole idea of a heap is that you give up control over where allocations happen in exchange for an easy way to allocate, free and reuse memory.

Indeed. For a movie scene depicting the sky including the Sun, you probably wouldn't want your TV to achieve the same brightness as the Sun. You might want your TV to become significantly brighter than the rest of the scenes, to achieve an effect something like the Sun catching your eye.

Of course, the same thing goes for audio in movies. You probably want a gunshot or explosion to sound loud and even be slightly shocking, but you probably don't want it to be as loud as a real gunshot or explosion would be from the depicted distance.

The difference is that for 3+ decades the dynamic range of ubiquitous audio formats (like 16 bit PCM in audio CDs and DVDs) has provided far more dynamic range than is comfortably usable in normal listening environments. So we're very familiar with audio being mastered with a much smaller dynamic range than the medium supports.

Life + death = mortality

is pretty good IMO, it is a nice blend of the concepts in an intuitive manner. I don’t really get

drug + time = occasion

But

drug - time = narcotic

Is kind of interesting; one definition of narcotic is

> a drug (such as opium or morphine) that in moderate doses dulls the senses, relieves pain, and induces profound sleep but in excessive doses causes stupor, coma, or convulsions

https://www.merriam-webster.com/dictionary/narcotic

So we can see some element of losing time in that type of drug. I guess? Maybe I’m anthropomorphizing a bit.

Ha! Everyone fails to make bus rapid transit comfortable and sustainable. That is the point - it’s publicly subsidized discomfort that gets you there. Along with everyone else more or less on time. In an urban environment.

Along. With. Everyone. Else.

It’s a public good. I’ve lived in both the EU and the U.S. extensively using buses and the argument that “American cities have failed” is just such a load of crap. I found buses just as tolerable in both including places like suburban Cupertino. They’re not supposed to be “sustainable” because they’re a vital service same as the water in pipes. And they’re not supposed to be “comfortable” if the frame of reference used are AC/sleek private vehicles.

The problem and the solutions have not changed. The only thing that has are the GPS enabled pocket computers we started carrying around. The GPS bit allowed for a real optimization. But the pocket computers also started feeding us with doubts about shit that works just fine.

I love it in theory(cant afford it), but I also love the delorean. We need way more stainless steel options.

>. Kei trucks don't look like American trucks and they're beloved, not hated

I hate them. They shouldnt even be legal to drive but by a 15 year import rule they can? They are total death traps but only because they might be marginally more safe than a motorcycle they are allowed?

Yeah, just imagine. I did. For hours yesterday evening I imagined.

Had a car killed my wife or unborn child, there would have been a legal trail and insurance.

Had the e-bike killed my wife or unborn child, there was neither. I doubt I could ever find the killer of the unborn child if the baby died later due to injuries-- there's neither license nor registration on an e-bike.

Pushing powered transportation into the unregulated, uninsured space is madness.

I have 2 kids and I kinda agree but I now stay with hotels with kitchens. I have not stayed at Airbnb since they ruined me and my family’s stay during my wedding. The flat we had didn’t have a working toilet and they refused to find us a new place. They just offered a refund (only if the host confirmed toilet can’t be fixed)

And this is after I explained it’s my wedding!!

Never again.

>That kind of code is not fine.

Depends on your definition of fine. Is it less readable because it's doing the straight forward thing several times instead of wrapping it into a loop or a method, or is it more readable because of that.

Is it not fine because it's slower, or does it all just compile down to the same thing anyway?

Or is it not fine because you actually should be doing different things for the different properties but assumed you don't because you let the AI do the thinking for you?

It's not clear to me that the _entire_ Neon stack is OSS and available to self-host (though they do share a lot of OSS code, which is great), and in any case, it's not currently supported/documented beyond some "local development" instructions, e.g. "We do not officially support use of autoscaling externally" [0]

> Can’t you use a cloud provider and have them host this for you?

If it really is all OSS, then I guess the moat is the impressive execution of this team.

Non-passkey based account access still works. As in i can go into my Google/Apple/MS account settings right now and in the security tab there's a ton of different options you can set.

Backup codes, sms phone recovery, alternate recovery email are all there in all of the above.

It's no different to forgetting your password/losing access to your password manager is it? As in i've literally at points lost access with passkeys (i only had 1 at the time) and the way i got back in was very straightforward and no different to losing access to a password manager. I got an email and typed my old password and i got back in and re-setup my passkeys.

> Ride-hail and delivery giant Uber is introducing cheap, fixed-route rides along busy corridors during weekday commute hours in major U.S. cities

Note that Uber is not introducing this in Europe or other cities where they have good public transport.

Instead of bus or trams that carry X people at once, reducing congestion, emissions, etc., you still have individual cars carrying one person at a time.

I ride Muni, BART and Caltrain all the time (I'm car-free in SF), and I have no idea what you're talking about. Here are the actual statistics of crime per vehicle mile on Muni: https://www.sf.gov/data--crimes-muni

Crime in SF and other big cities have been going way down. If anything, you're probably safer than ever in SF (and other common political targets like NY and Chicago).

Also, how can you know that Muni is more dangerous, if you're too scared to even get on in the first place? Can you really say your fear is based on facts and experience?

I reread that book recently and that immediately raised a red flag where the author makes it seems like the girl consents as in "well, I guess this is happening" then proceeds to portray her as a enjoying it and not really getting into the details of how a person/body may react regardless of a woman's (in this case) consent. This is much better portrayed in My Brilliant Friend with all the complexity of emotion of the victim towards the act and their reaction. I really wish if one thing could be changed about that book is just simply making the 15 year old character an adult.

I wasn’t always this way.

San Francisco has always had an edge to it, but it wasn’t nearly as bad as it’s become. I used to play chess at United Nations Plaza—yes, right there at the heart of the Tenderloin—with all kinds of interesting people. It had character, but it wasn’t unsafe like it is now. Things have truly changed, and not for the better.

Cruise control was one of the things I was thinking of, actually -- but the brake and accelerator on every car I've used cruise control with, still act as a brake and an accelerator. If I engage with the controls, they act in the way they'd act if the assistance was missing. Sometimes with warnings or stops (lane departure, speed limiters), often with smarter behaviour than might be apparent (regenerative braking, hybrid power trains, adaptive steering, radar/lidar support).

Airbus's Normal Law sounds more akin to a car that maintains its current speed and rate of turn if no inputs are given, so if you lift your foot off the accelerator then the car doesn't slow down and if you let go of the steering wheel then it doesn't wobble or re-centre. It might be easier to drive when the assistance is working, but it's not going to be easy to transition to regular brake, accelerator, and steering functions if the assistance needs to switch off.

I feel like "vibe coding" as a "no look" sort of way to produce anything is bad and will probably remain bad for some time.

However... "vibe architecting" is likely going to be the way forward. I have had success with generating/tuning an architecture plan with AI, having it create stub files/functions then filling them out individually. I can get pretty much the whole way without typing code, but it does require a fair bit more architectural thinking than usual and a good bit of reading code (then telling the AI to "do better").

I think of it like the analogy of blind men describing an elephant when they can only feel a single part. AI is decent at high level architecture and decent at low level production but you need a human to understand the big picture and how the pieces fit (and which ones are missing).

Fascinating! Will check this out.

Likewise, I thought it would be very cool to create a show written in a hypothetical future, that is set in our time period. The nature of the future society would only be revealed by how they choose to portray our time period, and which stories are told, just like we always put our own ideological framing on shows about the past.

> Why? Charge a use fee.

Who is paying for the maintenance of the extra bus lanes (or creating them in the first place), or the extra maintenance on the other lanes which get heavier use since some have been set aside as dedicated lanes.

Taxpayers.

So yeah, taxpayers funding Uber.

I'd rather fund public transport.

> It's simultaneously amazing to see and a depressing reminder of how badly western societies are crippled by rules of their own making.

It all comes down to corruption. In the west we are accustomed to thinking we are much less corrupt, but that is proving not to be less and less true every day.

Corruption is loyalty to a man over a mission. All systems that have good outcomes are when the man that people are loyal to (because he can punish dissent and reward loyalty, such as with wages) chooses a mission over their own self interest and enforce subordination to a mission over themselves.

China is a country that is capable of punishing their richest citizens, while the US and most of the west are not. China executed the executives that poisoned infant formula. Here in the US, our "law" let the Sackler Family promote addiction and then gave them a slap on the wrist while letting them use the "law" to reduce/avoid consequences.

China has more Rule of Law than the US right now.

Rule of law was thought to be a system where all citizens, including the rich, are protected from the government by due process, but rule of law is when the rich and powerful have limits on their arbitrary executions of power. Law exists to protect the weak from the powerful, law exists to bind power. In the west the rich have co-opted law as their tool.

> crippled by rules of their own making.

No, not our own making. The making of our richest. The rules in the west exist to solidify and cement the power of our richest and they use their money to pay for power consolidation giving them increasingly more power to compromise our laws for their interest.

China can do things because their power is working on behalf of their people, while in the west our power is working on behalf of the powerful.

> lack of bureaucracy

Who do you think is doing these things? Literally their bureaucracy. It requires people to organize and do those things. Bridges and tunnels don't get built without planning, funding, and execution, which is exactly what bureaucracies do.

The rich people in the west have been so effective at compromising institutions of power that "bureaucracy" is synonymous with "inefficiency." Their bureaucrats are trusted with the power to make things happen, while our elected officials bind their behavior and set them up for failure in order to justify privatizing their functions.

Waymo claims: "“Waymo provides more than 250,000 paid trips every week in some of the most challenging driving environments in the U.S..."

But also: "The company operates more than 1,500 vehicles across Los Angeles, San Francisco, Phoenix and Austin."

So not in the snow, ice, winding mountain roads, or any really "challenging driving environment"... more like flat city streets, hilly city streets, a desert, and giant, flat, sunny roads.

This guy is so cool, he uses the word "ratfucked"! Twice! Not just "fucked", but "ratfucked". Of course, congestion pricing was in fact implemented and remains in effect, so maybe not entirely "ratfucked"? Guess I'm not cool enough to understand. And because of his choice of words, people who are unfamiliar with this project don't even know what action(s) Kathy Hochul actually took that was/were detrimental.
