And age verification can't stop that no matter what. It's solely for restricting access to websites and apps.

> No amount of server side age verification will prevent kids and teenagers from sharing stuff.

Great, now convince the politicians and the voting public of that. See how things are going. It would be better to have some system in place that protects adults' privacy and restricts some underage access. Instead of having to upload your passport to every website 5 years from now.

1. in this iteration we used a 64% training 16% validation 20% testing split. In our current work we are testing with 10 fold / leave a subject out to get better analysis. 2. the esp dataset had heart rate up to 130 which is relatively high, and the raspberry pi data had people running in place etc... where the heart rate is higher

One issue with the latter is that tech is likely to advance fast enough that a subsequent probe launched a couple of decades later would overtake the first probe.

Regarding the former, various studies have been made and will certainly continue to be made: https://en.wikipedia.org/wiki/Interstellar_travel#Designs_an...

Exploration of the Very Local Interstellar Medium (VLISM) will likely come first: https://link.springer.com/article/10.1007/s11214-022-00943-x

It has to handle dirt, water, soap, five-year olds who pour sugar water over the robotic hands etc.

So far I've only seen these things in clean and dry environments, where they fold dry laundry, badly.

It looks like an absolute and expensive maintenance nightmare. Also, I'd worry about prompt injection or malfunction. Better carry an axe at all times:

I've driven all over the planet except for Asia and Africa. So far, no real problem and I think most drivers would adapt within a day or two. Greece, Panama and Colombia stand out as somewhat more exciting. Switching to left hand driving in the UK also wasn't a big problem but you do have to pay more attention.

Of course I may have simply been lucky, but given that my driving license is valid in many countries it seems as though humanity has determined this is mostly a solved problem. When someone says "Put a Waymo on random road in the world, can it drive it?" they mean: I would expect a human to be able to drive on a random road in the world. And they likely could. Can a Waymo do the same?

I don't know the answer to that one. But if there is one thing that humans are pretty good at it is adaptation to circumstances previously unseen. I am not sure if a Waymo could do the same but it would be a very interesting experiment to find out.

American suburban streets are not representative of driving in most parts of the world. I don't think the bar of 'should be able to drive most places where humans can drive' is all that high and even your average American would adapt pretty quickly to driving in different places. Source: I know plenty of Americans and have seen them drive in lots of countries. Usually it works quite well, though, admittedly, seeing them in Germany was kind of funny.

I'm giving this an upvote. There isn't enough philosophy thrown around here. My thoughts: I recently read a chapter in Michael Sandel's, "Justice" where-in he gives an account of the categorical imperative described by Kant; by the end of the chapter I was having a kind of, "secular mystical experience" where I realized, "the value of everyone around me" wasn't in their biological, social, or physical self-- all these, "human objects" possessed a kind a quality that, "simple objects" don't have-- αὐτονομία or autonomy. We as, "autonomous objects" can, "decide" to do something, "other than what our socially, physically, and biological contingent self" has commanded in the, "tangible" part of our expressive selves. This makes us, "subjects" and not, "objects" a categorization sense. For me a, "demonstrable immortality" would be that if our subjective self is, "separate" from our, "tangible" self even in some, "abstract" way it stands to reason that that part of us might not be even, "living in the universe" and might not be, "subject" (pun intended?) to the causality of the the universe that we seem to be interacting with through our bodies. The Bhagavad Gita, Bhagavat Purana, and many Christian treatise' describe the realization of soul as, "eternal, separated from activity, a silent witness..."

Food for thought! Food for souls? Perhaps! Thanks for some lovely engagement paulpauper. Namaskara and Hare Krsna pal.

Different things have been improving for the past 10 years. TTFX is in a good spot now, multithreading is in a pretty good spot now, GC issues for most people are basically solved. AOT compilation was pretty much the last big item that a lot of people wanted, and that has recently (within the last year) gotten to the point where the code exists, it's merged, and it will be releasing soon (and then spending the next year or two getting improved)

I have a genuine question -- how do these "non-paranoid" countries incentivize their staff to let people through while still catching true threats? That's ultimately the problem we're trying to solve. The 3 main models I've seen thus far are following

1) US model, guards only rewarded for catching criminals or deporting. Lots of false negatives at no cost to guards so they fuck with you a lot for no apparent reason. Canada somewhat similar.

2) LatAm model, bribes/theft to incentivize the to not burn up time with false negatives, but they sonetimes are rewarded enough for true positives to not just let them go.

3) "Swedish" model. Straight salary and then not give a fuck. Seems everyone gets through with not much thought.

LatAm model seems most practical of what I've seen but I haven't spent much time in Europe or Asia, mostly middle east, the Americas, and southeast asia.

I mean, it's not like I've never had to use public chargers. They just didn't have lines when I was there. Also, haven't encountered a broken charger. (Seattle area.)

The thing that actually bothered me the most is needing a different stupid app for every one of the ~5 different networks to pay, instead of just inserting or tapping a credit card. But this is mostly an occasional-user problem; the pain probably falls off dramatically once you've already registered for everything.

Charging at home is a great experience.

In K-12 education, there are two opposing views related to individual student achievement:

A) 'pro-excellence': raise the ceiling, aim to maximize the realization of human potential.

B) 'pro-equity': raise the floor, narrow the 'achievement gap' at all costs, including lowering the ceiling.

Viewpoint B is what guides much of district-level education policy in the US.

That’s not necessarily true. If the embedding model hasn’t been trained on data you care about, then similarity might be dominated by features you don’t care about. Maybe you want documents that reference pizza toppings, but the embedding similarity might actually be dominated by the tone, word complexity, and the use of em dashes as compared to your prompt. That means the relative ordering might not turn out the way you want.

I haven't closely followed which rides have drivers where, and what is driven by Tesla vs what is regulatory -- but I thought some "drivers" were still in the passenger seat in Austin?

At any rate, I don't think they are revoking their prior promises. I expect them to deliver L4 autonomy to owners as previously promised. With that said, I'm glad they are ceasing that promise to new customers and focusing on what the car does today, given how wrong their timelines have been. I agree it's shitty if they don't deliver that, and that they should offer buybacks if they find themselves in that position.

I implemented a casino in assembly for college. Started with a Mersenne Twister and added a few pure chance games like roulette and slots.

The PRNG was trivial. Managing the user's bank balance, switching between games, making the roulette wheel 'spin' by printing a loop of numbers slower and slower was painstaking, error ladden work.

State doesn't just contributing to complexity, it is complexity.

>TDD is useful in some situations, yep totally. Pair programming is useful in some situations, yes. Continuous integration; yes, much of the time. Frequent feedback; yes, sometimes

For production code I do pretty much all of these, always - at least insofar as it is possible (e.g. willing pairing partner).

Im curious to know under which scenarios you think im doing something wrong. Coz I dont think i am.

Yeah, I apologize for the Android bugs. I’d mostly intended for it to be a desktop app, and tested it on Linux and Mac, then did a couple mobile additions and tested it on iOS. I didn’t expect that Android would behave so much differently, particularly since it’s all in a browser, so that was pretty naive.

I’ve downloaded Android Studio for testing, so I’ll get to work figuring out where the bug is coming from.

The 500,000 number is the number of books that are part of the settlement. If they downloaded all of Libgen and the other sources it was more like >7Million. But it is a lot of work to determine which books can legitimately be part of the lawsuit. For example, if any of the books in the download weren't copyright (think self published) or not protected under US copyright law (maybe a book only published in Venezula) or it isn't clear who own the copyright then that copyright owner cannot be part of the class. So it seems like the 500,000 number is basically the smaller number of books for which the lawyers for the plaintiff felt they could most easily prove standing.

I like my comments, they’re little droppings of my thoughts at the time that I can go back to. I delete many of them, if they get a single downvote, or if I think about them for 10 minutes after and decide not to have them permanently recorded. They don’t run my life, and it’s only HN and lobsters I leave them on. I just don’t assign much of my life’s purpose to these farts in the wind, and turns out it’s fine.

1. the train test in here was leaky, but in our current iteration of the work we do 10 fold train / test without leakage 2. There was no different in performance at higher HR values, the rpi data contained people running in place and our performance on that was as good as laying down 3. a simple presence detection model would solve that and also the algorithm already covers this

I'm a big believer that animations need to validate what you already know, they aren't the information itself.

This means, if you turned animations off you would still work as fast and understand the flow the same as if animations were enabled.

For me, the purpose of animations is to soften the UX journey, and to confirm what I already knew, by giving me small indications that yes, the UI is truly in the state I expect it to be.

Such as fast highlighting of on hover items, so I don't have to correlate the mouse position to the control.

I love that example of tool tip popups taking 0ms once you have popped up one, that is a clear signal that the UX understands you are trying to learn more about the controls you're hovering over.

That's a perfect representation of how animations signal understanding of your UX journey.

I’ve found that while trying to write down the ideas in my head, it’s very easy for me to lose my train of thought if I edit while I write, which I can’t seem to help but doing. Not being able to go back at all, or to glance at anything I’ve already written, has helped me keep my inner dialogue moving without interruption. It felt odd at first, but I very quickly got used to not editing myself.

Imagine if Google, which presents itself as a supporter of open source, had clear support policies so that when it ended support for a product, the open source community could take over. Think about how much e-waste that could prevent and how quickly it could make Google the default recommendation.

At this point I’ve thrown out so much Google hardware that was end of life but still operating I’ve become just the opposite — I constantly suggest people don’t use their hardware.

There are attempts, but they all suck IMHO :( Someday I'll get around to doing this in Three.js for real, if no one beats me to it. It's shocking that we have a million 3D sites to visualize LEO satellites and plenty to visualize the solar system, but our stellar (much less galactic!) neighborhood is all super outdated stuff only.

I guess the sad reality is that these tools aren't that useful for anything but diagramming the odd interstellar rock.

> I have no idea where you managed to find any feelings in my replies, and I will ignore the personal attacks.

Your username is fsflover and your posts clearly have an ideological bias that favours purely open source solutions even if it goes against reason.

> The linked security-related arguments aren't reasonable at all. They talk about improving users' security but instead the actual result is less security for the majority of people, due to (1) the high price of the supported hardware, (2) reliance on Google hardware not trusted by many users

All SoCs are a black box and all of them are made by untrustable companies that are likely already working with the security services of whatever country they're R&D'd or manufactured in. There is no good solution to this, so they picked the best worst option.

Nonetheless, most of the evidence that is available shows that GrapheneOS on Pixels are the most secure phones currently available. So, clearly not security theatre, whereas if they also supported phones that didn't even let you lock the bootloader it absolutely would be.

GrapheneOS isn't to blame for every other phone manufacturer dropping the ball.

>something like Podman w/ RedHat behind it is unlikely to be limited in the same way a lot of community OSS projects are

exactly. I've built podman for debian. It's not an esoteric target. It gets a little hairy with all of the capabilities stuff and selinux, but it's feasible. Give me, I don't know, $10k a quarter and I'd probably do it.

llama2 is pretty old. ollama also defaults to rather poor quantizations when using just the base model name like that - I believe that translates to llama2:Q_4_M which is a fairly weak quantization(fast, but you lose some smarts)

My suggestion would be one of the gemma3 models:

https://ollama.com/library/gemma3/tags

Picking one where the size is < your VRAM(or, memory if without a dedicated GPU) is a good rule of thumb. But you can always do more with less if you get into the settings for Ollama(or other tools like it).

For what it's worth the friction exists for a reason, conflicts of interest.

The lawyers suing Anthropic here will probably walk away with several hundred million dollars - they have won the lottery.

If they managed to extract twice as much money from Anthropic for the class, they'd walk away with probably twice as much... but winning the lottery twice isn't actually much better than winning the lottery once. Meanwhile $4500 is a lot more than $2250 (the latter is a reasonable estimate of how much you'll get per work after the lawyers cut). Which risks the lawyers settling for less than is in their clients best interests so that they can reliably get rich.

Personally (not a lawyer or anything) I think this settlement seems very fair, and I expect the court will approve it. But there's definitely been plenty of class actions in the past where lawyers really did screw over the class and (try to) settle for less than they should have to avoid risking going to trial.

It is noticeable, though.

> Yes EVs can keep their weight low, but it's a lot more weight to deal with.

Define a lot? It's a few hundred pounds, excepting pickups.

> Starting from highway speeds? EVs start to look real slow.

Maybe a Leaf or a Bolt. But I would be happy to put my Model 3LR or F-150 Lightning up against something like a Camaro SS or Mustang GT from a highway roll -- I'll still win.

Different for me.

I get reduced anxiety only for the afterglow the day after. No feelings of interconnectedness (that went away as I grew older)

Microdosing has allowed me to reduce anxiety daily for a little longer, even with tolerance but overall I wouldn't take it long term.

Cutting out coffee has a better effect reducing it than psychedelics for me and maybe the microdosing effect was due to me replacing coffee with it...

What really helped me with anxiety was NAC. Antioxidants are great.

HomeAssistant supports a bunch of home automation systems, including local-only ones like ZWave and Zigbee*. A search for "zwave thermostat" comes up with a lot of results, though I couldn't say how difficult it might be to configure them (I'm only using simpler devices like switches and sensors).

* There are internet-connected controllers and local controllers so you'd also want a local controller. I've used an Aeotec Z-Stick for ZWave devices for around a decade, it plugs into USB, HomeAssistant accesses it directly, and the ZWave network itself is connections between the Z-Stick and the devices without the internet.

Yeah I think their early success with Tesla Vision was faster than expected, it went to their heads, and they underestimated the iteration and fine tuning needed to solve the edge cases. It's difficult to predict how many reps it will take to solve an intricate problem. That's not to excuse their public timeline -- their guidance was naive and IMO irresponsible -- but I don't think it was in bad faith.

I suspect that ruling legally gets wiped off the books by the settlement since the case gets dismissed, no?

Even if the ruling legally remains in place after the settlement, district court rulings are at most persuasive precedent and not binding precedent in future cases, even ones handled by the same court. In the US federal court system, only appellate rulings at either the circuit court of appeals level or the Supreme Court level are binding precedent within their respective jurisdictions.

This is really encouraging! Commented elsewhere in the thread but this was one of the main odd points I ran into when experimenting with ClickHouse, and the changes in the PR and mentioned in the recent video about join improvements (https://www.youtube.com/watch?v=gd3OyQzB_Fc&t=137s) seem to hit some of the problems. I'm curious whether "condition pushdown" mentioned in the video will make it so "a.foo_id=3 and b.foo_id=a.foo_id" doesn't need "b.foo_id=3" added for optimal speed.

I also share nrjames's curiosity about whether the spill-to-disk situation has improved. Not having to even think about whether a join fits in memory would be a game changer.

> if it comes down to his lead foot

Yes. Some people are binary drivers, regardless of drivetrain. But a very responsive EV, especially something like a Tesla Performance trim in sport mode or F-150 Lightning in sport mode, with an unskilled driver can definitely make you seasick. Most drivers who can modulate the pedal do just fine, though.

The only real problem with Teslas is that they don't have an option to go without one pedal driving. Some drivers really aren't suited for 1PD, frankly.

The larger engineering lesson from that is you're probably better off making standard solutions work for your situation than custom solutions. The wider gauge solved(?) the stability problem, but at the cost of always needing custom rolling stock, but more importantly, making Bart build-out significantly more expensive and unable to take advantage of existing track. That hurts the viability of the Bart ecosystem.

I primarily use Podman but it is worth noting a few things:

- Podman is usually used "rootless", but it doesn't have to be. It can also be used with rootful containers. It's still daemonless, though it can shim the Docker socket (very useful for using i.e. Docker Compose.)

- Docker can be used in a rootless fashion too. It will still run a daemon, but it can be a user service using user namespaces. Personally I think Podman does much better here.

Podman also has some other interesting advantages, like better systemd integrations. Sometimes Kubernetes just isn't necessarily; Podman + Systemd works well in a lot of those cases. (Note though that I have yet to try Quadlets.) Though unfortunately I don't think even the newer Quadlets integration has some basic niceties that Kubernetes has (like simple ways to do zero downtime deployments.)

Way to ruin another quality thing you assholes.

In my opinion, there are two factors at play: (1) social division and (2) it’s easy in America for self-interested people and organizations to block progress by weaponizing due process.

I’ll expound on the first point. European countries and East Asian countries generally have a stronger sense of cultural cohesion, while America has many deep divisions such as:

1. Social liberalism versus social conservatism, which also correlates to a secular versus cultural Christian worldview.

2. Racial and ethnic divides with sometimes centuries of bad blood

3. Class divides between the poor, the working class, the middle class, and the wealthy.

These divisions make it harder for people to come together to work for the common good. There are some politicians who shamelessly act in the interest of their voter bases with little regard for those outside their bases, and there are also people who are suspicious of even well-intended proposals since there may be hidden motives behind them.
