jo909 commented on A 10-Year Battery for AirTag elevationlab.com/blogs/ne... · Posted by u/dmd

Does that fix it or make it worse? If you have 10 smoke detectors and they end up randomly staggered so this happens once a year, and you can't replace the batteries anymore... that seems worse than the old system which completely eliminated this issue if you just replaced them all every year or two on a schedule.

Remember that you are supposed to replace the entire thing because the other components like the sensor or simply capacitors also age. It is a very cheap safety device and simply not worth taking any risks by stretching it to say 15 years instead. The proper way would be to replace them while they were all still fine by making a note in the calendar.

There are two cases:

Your products are faulty and at least one has not made their intended 10 year lifespan. I'd change them all for better ones.

Or

They have reached their lifespan and you only noticed because the first one failed. I'd replace them all.

I will repeat my question from one of the previous threads:

Can someone explain these Aider benchmarks to me? They pass same 113 tests through llm every time. Why they then extrapolate ability of llm to pass these 113 basic python challenges to the general ability to produce/edit code? Couldn't LLM provider just fine-tune their model for these tasks specifically - since they are static - to get ad value?

Did anyone ever try to change them test cases or wiggle conditions a bit to see if it will still hit the same %?

> Couldn't LLM provider just fine-tune their model for these tasks specifically - since they are static - to get ad value?

They could. They would easily be found out as they loose in real world usage or improved new unique benchmarks.

If you were in charge of a large and well funded model, would you rather pay people to find and "cheat" on LLM benchmarks by training on them, or would you pay people to identify benchmarks and make reasonably sure they specifically get excluded from training data?

I would exclude them as well as possible so I get feedback on how "real" any model improvement is. I need to develop real world improvements in the end, and any short term gain in usage by cheating in benchmarks seems very foolish.

Humans not only use vision, they use sensor fusion. Combining what you see, hear, touch, etc. Your body can perceive acceleration, for example.

On top of that, you have theory of mind. For example, you have 4 cars next to you, all of them with opaque windows that do not let you see the driver:

A) a loud sports car with a bunch of modifications, decals and racing related stuff

B) a grandma car with cat related stickers

C) an unmaintained car with collision damage, and loud music coming from it

D) a family station wagon with a baby on board sticker and other family related stuff

Your mind will process what it sees and quickly assign each one of those cars a different personality. A and C will likely be perceived as riskier cars, B and D will be likely perceived as safer cars. You will avoid A and C and remain unconcerned about B and D.

The problem with the self-driving cars right now is that they only perceive the road as bodies that move.

And assumption like that are probably a great source of accidents, our mind needs to take some shortcuts like that and isn't always right. Grandmas car got sold last week and daddy is alone in the car and late for work and will be racing to get in front of you.

I'd rather have a computer keep track of everybody just the same but with millisecond reaction to all changes. Something that I can't do lacking eyes all around and processing power.

Interesting that the colo electricity cost goes up that much, that’s a lot more expensive than what I will pay as a normal consumer, I’d have thought they’d get better discounts.

jo909 · 3 years ago

I'd guess that they used to have very good discounted contracts but are not able to renew them anymore.

The cost they charge also includes the cooling, so you could see it as for example 30c/kWh for power, 15c/kWh for cooling to compare it to a consumer contract. Maybe they have published their ratio of that split "on average" before.

Why would you think money is not about belief?

If people stopped believing in fiat, there would be a major bank run.

So yes, the value of crypto, just as like the value of fiat, is based on belief.

jo909 · 4 years ago

I do not understand why one would fetch stacks of paper from the bank if one believes toilet paper is the more valuable type of paper you should hoard and maybe also trade with.

Seriously, why would the end of fiat cause a bank run? I would expect it would cause a switch back to trading physical goods directly, or the emergence of another currency-like thing or good (like cigarettes might have been in the past).

> This is an interesting option for people who need a specific Raspberry Pi hosted somewhere.

What is that use case though? The page says that they only host regular Pis and optionally a USB SSD. So they can't do anything that a regular cloud server can't do - no custom hats, etc.

I have a Pi 4 home server, and the biggest issue right now is that my home upload is a bit weak for remote video streaming. So this product could interest me, in theory - saves me from having to migrate all my data & configuration to a cloud server. But I would rather pay Hetzner a very similar amount of money to get a VPS that's about as powerful as a Pi (probably more) and still have the physical Pi here at home as a fallback.

Maybe there are ARM-specialized, highly distributed tasks for which a fleet of Pis is particularly efficient?

"To ensure that every Pi at our decentralized locations always has enough network throughput, the uplink and downlink is fixed at 10 Mbps."

Not sure about your use case, but for me that is way less bandwidth than I have at home.

rubatuga · 5 years ago

Is there anybody interested in building or using a service that routes static public IPs to self-hosted servers, over WireGuard? I made a prototype a week ago, here's the homepage:

https://hoppy.network

I realized that I didn't want to ever deal with port-forwarding, NAT, or dynamic DNS and decided to create this. Message me if you want a signup link.

jo909 · 5 years ago

I'm sure there is and will be demand for good static IPv4 tunnel brokers. I'm personally fine with dealing with dynamic DNS and port forwards for my home setup for now, but once I no longer have a public IPv4 assigned I would be a potential customer.

How do you deal with the global scarcity of IPv4-addresses that you would need to scale your service? I think this can only work long term if you own the address space yourself and are not dependent on some specific provider or cloud.

Also very important is a local endpoint to get a reasonable end to end latency.

This is a subsidiary of OVH.

No, scaleway is owned by the same parent as online.net, which is a competitor to OVH. Both are french though.

I thought this would be about the psychology of “getting inside” someone’s head. I think it’s a very interesting phenomenon when someone says something to you and you can’t seem to shake it, and it bothers you for days or weeks. I’m very sensitive to it. I believe it’s a very important window into how the mind works. That’s one reason why it’s interesting. The other is that understanding this phenomenon would be very powerful — to never allow anyone to “get under your skin” would make you a much more powerful and productive person.

I have read that the unibomber, before he started bombing, was subjected to an experiment under the mk-ultra program. The experiment was psycological cross-examination. Ted was taken into a room and asked about certain things, things that were probably very important to him — fundamental beliefs that perhaps he didn’t even realize were fundamental to his psychology. Then, with all of that established, he was cross-examined and inconsistencies in those beliefs were brought to his attention or in some way de-stabilized. It was after this that his descent into insanity began which ultimately resulted in the bombings. This concept of “getting inside your head” is much more important than it is given credit for — completely untapped and unexplored as far as I can tell. I really wish I could understand it. But I can’t really find much when I google around for it. Nobody seems to talk or think about this online. Not in the way I do which is viewing it as an exploit in the human mind.

jo909 · 7 years ago

There is a very large industry that specializes in exploiting the human mind: advertising/marketing.

Of course the behavior/opinion changes they are after are somewhat limited and not too bad, and the effectiveness debatable, but they are trying hard. And machine learning is already in use.

> With root access to the VPS

And with root access to the VPS host, you can just extract private keys from the VPS ram and proxy the connection, logging it all the while..

so no, this claim is not tenable even at the VPS level.

jo909 · 7 years ago

This is what makes this no better than any other VPN service. I still need to completely trust that the provider is not watching me. Even with full hardware access, there could be an invisible sandbox or hardware DMA to some chip I can't see. There is no easy scalable solution to avoid this in a technical level. But you can be one anonymous user in a sea of many others and hope for the best, which is why I'd advise to go to a trusted mainstream VPN provider.
