I would be perfectly happy with a solution where browsers show a scare screen for self-signed certificates on the public internet but a benign-looking "Do you want to trust this certificate?" screen for 192.168.0.0/16, 10.0.0.0/8, 172.16.0.0/12 or mDNS .local domains.

”If people try to hold us accountable by talking among themselves about our actions, it takes away valuable time that could be used to do vaguely defined other actions” is not a terribly strong defense of moderation opacity.

Especially during a time when there is strong authoritarian pressure to suppress certain kinds of speech, and the result of your unaccountable actions is the suppression of that speech. The benefit of the doubt is rapidly being lost here.

edit: thank you for taking the time to email and post the response.

> People are busy, some people have kids.

It takes 30 seconds to return a cart. Nobody is so busy or has so many kids as to not be able to wheel the cart into the cart stall. If you have that many kids, then you probably can't really safely grocery shop in the first place.

The reason it gets brought up is exactly because it's a small thing to do that is generally accepted as being the right thing to do. You basically won't find someone defending not wheeling back the cart as being the right thing to do (outside of maybe a true emergency).

Better, it’s a small step to “being a small part of something that’s doing a little evil to a shitload of people (say, working on Google ~scams targeting the vulnerable and spying on everybody~ Ads) is not just OK, but good, as long as I spend a few grand a year buying mosquito nets to prevent malaria, saving a bunch of lives!”

Which obviously has great appeal.

As a fellow former grocery store employee, I can agree about the “break up the monotony” concept from the narrow POV of the bored worker.

It is an inconvenience though, even if as insignificant as an eyesore for others, or the landscaper who may need to remove shopping carts from the planter to do their work.

You could apply similar logic to people who carelessly throw trash in the recycling bin or on a sidewalk where it’s someone else’s job to clean up after them. I’ve seen people go as far as to say they are graciously “providing a job” for someone else when they throw their refuse in the recycling bin.

The fact that the shopping carts are such an inconsequential thing to shrug off is what makes them a great litmus test — will you do the right thing simply because it’s the right thing to do, even when there is so little at stake

I don't see anything in your comment that directly disagrees with the one that you've replied to.

Maybe you misinterpreted it? To me, It was simply saying that the flaw in the EA model is that a person can be 90% a dangerous sociopath and as long as the 10% goes to charity (effectively) they are considered morally righteous.

It's the 21st century version of Papal indulgences.

I think it might make more sense to use WebAssembly and make them as extensions which are included by default (many other things possibly should also be made as extensions rather than built-in functions). The same can be done for picture formats, etc. This would improve security while also improving the versatility (since you can replace parts of things), if the extension mechanism would have these capabilities.

(However, I also think that generally you should not require too many features, if it can be avoided, whether those features are JavaScripts, TLS, WebAssembly, CSS, and XSLT. However, they can be useful in many circumstances despite that.)

gemini://kennedy.gemi.dev

There are ~4K hosts and ~1M documents/images/files which make for nice playground with experimenting with crawlers, indexers, and more. Its a nice hobby. Lots of primarily static sites, and CGI is used to add some interactivity:

NYC tunnels have outsized cost, but even tunnels that cost 10% of that would not be cheap. Most of the NYC subway was built quickly and relatively cheaply by digging trenches and covering them later, not by boring tunnels. NYC used to use elevated trains a lot, and still has plenty of those outside Manhattan, but they have other downsides, such as noise.

NYC subway has two drivers per train due to the trade union resistance. Very understandable, even though not really necessary.

Self-driving buses could be also remotely driven in situations that require special handling, by a smaller number of drivers.

As usual, it mostly takes a political will, the technology is not rocket science; one of the poster kids of that is Curitiba in Brazil.

I must admit, I don’t get the wish for 3.5mm headphone jacks in 2025. Already six years ago, with a phone that actually still had a headphone jack, I bought myself for just a few euro a Bluetooth DAC (a FiiO) that had superior sound quality to any phone’s audio-out that I had ever used. With a Bluetooth DAC (or with any USB-C to 3.5mm converter that costs pennies) you can still use whatever wired headphones you want to use.

Physical keyboards were nice back in an era when the web welcomed longform text, and I miss my Nokia N900. Nowadays, though, the web ecosystem that one typically uses from a phone is a cesspool, and for serious things I’ll just use my real computer.

> a holy grail of energy production

Since you're comparing it to nuclear, I'm assuming you mean electricity production here, not energy production?

It's always worth remembering that electricity only accounts for ~20% of global energy consumption (in the US it's closer to 33%).

I suspect people confuse these two because in a residential context electricity plays a huge part of our energy usage, but as a whole it's a smaller part of total energy usage than most people imagine.

But any serious discussion of renewable energy should be careful not to make this very significant error.

The Lawrence Livermore National Laboratory publishes a great diagram of US energy use: https://flowcharts.llnl.gov/sites/flowcharts/files/2024-12/e...

You can buy (almost?) any part directly from Tesla as a plain Joe [1], but you may need a VIN for certain parts (mainly the actual computers?).

In the event you want to DIY a repair, Tesla publishes all their service manuals they use at their service centers (e.g. [2]) and you can can even use the exact same software their technicians use for the deeper repairs, albeit at a price that is expensive if you're a plain Joe, but for a repair shop it doesn't seem to be terribly expensive.

On the topic of 3rd party parts, there isn't quite as robust a marketplace.

I fully understand that waste management of fission reactors is a Very Big Deal. But I still stand behind the argument that opposing nuclear power in the 70s and onward is possibly the biggest own goal the environmental movement has ever achieved.

At worst, nuclear waste contaminates a discrete section of the Earth. Climate change affects literally everywhere. The correct answer would have been to aggressively roll out fission power 40-50 years ago and then pursue renewables. You can argue that other solutions would make fission power obsolete, but we would have been in a much better spot if it'd at least been a stepping stone off fossil fuels. Instead, we have 40-50 years of shrieking and FUD from environmentalists over an issue that can be kept under control with proper regulation. The US Navy has operated reactors for over 60 years without incident, proving it can be done with proper oversight.

TL;DR nuclear has issues, but I'd take it over coal every day and twice on Sundays, at least until something better can scale.

You mention Costco as an example and claim that the return is (on average?) 30 feet away from your vehicle? Did you mean meters? Either way quite an underestimation. At our local meglo market (owned by Kroger) there isn't a return for every parking aisle. The distance and exposure to traffic to use a return is quite variable and can be significant. My local store is large enough that they have a cart returner as a dedicated position.

(Not OP)

This is pretty well established. See for example:

https://www.anthropic.com/engineering/code-execution-with-mc...

https://blog.cloudflare.com/code-mode/

Code (including shell scripting) allows the LLM to manipulate the results programmatically, which allows for filtering, aggregation and other logic to occur without multiple round trips between the agent and tool(s). This results in substantially less token usage, which means less compute waste, less cost, and less confusion/"hallucination" on the LLM's part.

If one comes to the same conclusion that many others have (including CloudFlare) that code should be the means by which LLMs interface with the world, then why not skip writing an MCP server and instead just write a command-line program and/or library (as well as any public API necessary)?

> Just try to help the people around you a bit more. If everyone did that, we'd be good.

This describes a generally wealthy society with some people doing better than average and others worse. Redistributing wealth/assistance from the first group to the second will work quite well for this society.

It does nothing to address the needs of a society in which almost everyone is poor compared to some other potential aid-giving society.

Supporting your friends and neighbors is wonderful. It does not, in general, address the most pressing needs in human populations worldwide.

It wasn't just one killer app deprecation/removal away. RSS was also integrated into browsers at one point, and then removed. You wouldn't need a social media feed if your browser home page already gave you your timeline, and if it were trivial for any web page to add a "subscribe" button. But instead of known, proven use-cases that have clear demand, we get Javascript APIs for niche stuff like flashing firmware onto USB devices.

> This is a great example of how ADTs can be implemented in C by emulating classes, despite the loss in brevity.

I don't see it that way, mostly because ADTs don't require automatic destructors or GC, etc, but also because I never considered a unique/shared pointer type to be an abstract data type

I return carts, but I too worked at a grocery store and so did a fair amount of cart wrangling, a lot of it during the Phoenix summer. It was very zen, watching the monsoons build. Certainly didn't mind it.

Stores in the US provide a lot of services to shoppers; bagging groceries, taking them out to your car for you, etc. I don't see why collecting your cart can't be part of that. The exception here is stores like dollar tree, where employees are treated like absolute trash by corporate.

not disagreeing with your point here, or in the follow-ups of the pain of https for "local network" apps... but I really wish that we could get to a place where we could get away from this distinction. Obviously, ipv6 is not that easy or realistic, but that really is, imho, the "right" long term answer.

Having gone down the path of being able to just spin up "local" services that get a publicly routable (but most often firewalled off) ipv6 IPs and then good DNS integration is really neat... but still requires lots of technical chops. I wish that weren't the case

If everyone did that, lots of people would still die of preventable causes in poor countries. I think GiveWell does a good job of identifying areas of greatest need in public health around the world. I would stop trusting them if they turned out to be corrupt or started misdirecting funds to pet projects. I don’t think everyone has to donate this way as it’s very personal decision, nor does it automatically make someone a good person or justify immoral ways of earning money, but I think it’s a good thing to help the less fortunate who are far away and speak a different language.

People who wonder about this stuff should travel to Japan.

It is sort of amazing and uplifting to see a whole society with a high level of good behavior.

- People trim their bushes and trees (they frequently look like Dr. Seuss trees)

- The sidewalks are clean, even in the most urban environments

- I've seen women leave their purse on the table when they go to the bathroom.

- People wait to cross the street

- Cars are carefully parked and aligned inside the lines

- People wait in line

- stores are well organized

I'm now completely torn! I always return carts just out of habit as a nice thing to do, but I totally see this as a legitimate reason not to return them! I never worked at a grocery, but I have worked at other jobs where there was that one task that got you out of sight of management so you could take your time and mentally relax for a while. Taking the trash to the dumpster way out back, restocking the walk-in fridge from the basement, etc. It was less about not working, as it was about the freedom.

Then again, they still have to go out to the cart return areas to collect them which takes time, so in that sense leaving carts around just makes their job a bit harder. Hmm. Not sure now!

>People will buy a Steam Machine who would not buy a Linux desktop.

I have a Linux desktop and a mental block around playing games on a computer. The computer is supposed to be where I work or write code, etc. If I have leisure time, I "should" do something away from the computer.

Getting a steam deck let me shake some of that. I'd be very tempted by a box that is a Linux computer, but for fun use only.
by cogman10 | 2025-11-17 19:21:17+00:00
If everyone did it then you'd probably have a dedicated person to fetch the carts doing that basically throughout their shift. The store still needs the carts for more shoppers and with everyone putting them in the grass that process ends up taking longer.

Except for particularly busy times, I don't think you'd see major pile ups.

But I generally agree with what you are saying. It's a valuable question to ask "what if everyone did this".

The perfect philosophy for morally questionable people would just be to ignore charity altogether (e.g. Russian oligarchs) or use charity to launder strategically launder their reputations (e.g. Jeffrey Epstein). SBF would fall into that second category as well.

I don't see mention of parenting.

Imagine you’re in a hurry. Your child is tired and hungry, and you are too. You’ve just loaded the groceries into the trunk and finally gotten your child strapped into the car seat. You think for just a moment that you're done. But then you realize: you still need to return the shopping cart. You should have loaded the groceries, locked the car, gone back to the cart return and then carried your child back to the car to load them into their car seat.

Now you’re faced with a dilemma with three bad options — do you take your child back out of the car, leave them unattended for a moment, or abandon the cart and go home?

Id think this being the 'official' political position , it would be referring to the end of hostilities when the armistice was signed.Legally there was no ceasefire/capitulation etc and i would suggest as far as the North are concerned barring outside interference they would have prevailed. Hence the stressing of the position that they are one entity 'politically' - certainly not that 'physically' they are one untit , also why they would hold/reunification talks from time to time and family relatives exchanges between the two.

They are cognizant that there is a DMZ , and that theere exists a polity on the south that keeps sending usb filled baloons , propaganda loudspeakes blaring on the Border. So mostly a poltical position being staked out , which is also why the maps only have Palestine and Western Sahara.Not because they are unaware of the situation insitu but geopilitically they are staking their claims.

It's a solution. There are better solutions, and far worse solutions (anyone who has worked to get a deposit back on a college rental has probably developed a few of their own), and most of them are all still fine because drywall isn't (shouldn't be) structural.

Crucially, even if you are completely unwilling to take a stab at a fix yourself, hiring a local handyman to patch a hole via some good enough technique should still be far cheaper in most places than buying a nice new TV.

But nothing is gonna ever beat buying a 2nd-hand framed picture or plaque or movie poster or grabbing a flyer from the junkmail on your porch and tacking it over the hole... And if you're determined to fix holes with a TV, you can probably find one used for about as cheap / free as any of the other choices. Which is what makes this such a stupid example - the cost of TVs, like framed images or furniture, spans from $0 to "as much as you're willing to pay". Hiring someone can also be arbitrarily expensive, but can by definition never be 0. So the comparison is rhetorical trickery and demonstrates nothing.

...other than, apparently, Andreessen's dissatisfaction with paying tradespeople.

Im pretty deep into this topic and what might be interesting to an outsider is that the leading models like neuralgcm/weathernext 1 before as well as this model now are all trained with a "crps" objective which I haven't seen at all outside of ml weather prediction.

Essentially you add random noise to the inputs and train by minimizing the regular loss (like l1) and at the same time maximizing the difference between 2 members with different random noise initialisations. I wonder if this will be applied to more traditional genai at some point.

Amusing, albeit mostly irrelevant, sidebar...

On Facebook, there's been this running gag/joke/meme/whatever going for at least the last year, where anytime the official North Carolina Wildlife Resources Commission page posts anything, a large portion of the comments quickly turn into a discussion of the merits (or lack thereof) of pet raccoons[1].

I don't know exactly how it started. Somebody innocently asked "How do I get a permit for a pet raccoon?" and the page replied "You can't, they are illegal in NC" or something prosaic like that I imagine. But it became a big "thing" and now raccoon talk is everywhere. The page controllers play along with it, which is part of why it's kept going so long I guess. But sometimes they'll get semi-serious and post something like

"Look, all joking aside, the reason pet raccoons are not allowed is because no matter how friendly raccoons look, they are wild animals, not domesticated, and they can be a hazard to you, and your family and <blah, etc, etc>".

Soooo... I'm just waiting to see somebody post this very article in a comment on that page with a note saying "Suck it, NCWRC!" (all in a spirit of good fun, of course).

[1]: or one or more of another of a small set of topics, including flounder, pet alligators, armadillos, UFO's, and the possibility that the person running the page is the product of secret government genetic engineering experiments involving "all of the above". It's... complicated.

EDIT:

Welp ,that took about as long as I expected. ROFL.

On one hand, it is an example of the total-order mentality which impregnates society, and businesses in general: “there exists a single optimum”. That is wrong on so many levels, especially with regards to charities. ETA: the real world has optimals, not an optimum.

Then it easily becomes a slippery slope of “you are wrong if you are not optimizing”.

ETA: it is very harmful to oneself and to society to think that one is obliged to “do the best”. The ethical rule is “do good and not bad”, no more than that.

Finally, it is a receipt for whatever you want to call it: fascism, communism, totalitarianism… “There is an optimum way, hence if you are not doing it, you must be corrected”.
