a database scaling dramatically up and down /under load/ and expecting it to perform the same as steady state seems a bit weird, vs a single, beefy database with a beefy ingest job and a bunch of read only clients searching it?

like you're more likely to encounter two phases (building the DB in heavy growth mode, and using the DB in light growth heavy read mode).

A business that doesn't quite yet know what size the DB needs to be has a frightening RDS bill incoming.
Aggregates are a work in progress. We're going to implement them in this order:

1. count

2. max, min, sum

3. avg (needs a query rewrite to include count)

Eventually, we'll do all of these: https://www.postgresql.org/docs/current/functions-aggregate.....
If you got a specific use case, reach out and we'll prioritize.

AC Transit (eg: East San Francisco Bay) performed a detailed 2 year study (July 2020 - June 2022) comparing newer Hydrogen Fuel Cell & Battery -powered buses to existing Diesel, Fuel Cell, & Hybrid -powered buses, 5 of each type. The key results are the Hydrogen Fuel Cells have significantly more expensive infrastructure, fuel, and maintenance costs than Battery. However, both technologies are still less reliable than Diesel.

The results are broken down into 4 volumes, each covering 6 months. You can read them here: https://www.actransit.org/zebta
I think the hard question is whether those wins can be realized with less effort than what we’re already doing, though.

What I mean is this: A brain today is obviously far more efficient at intelligence than our current approaches to AI. But a brain is a highly specialized chemical computer that evolved over hundreds of millions of years. That leaves a lot of room for inefficient and implausible strategies to play out! As long as wins are preserved, efficiency can improve this way anyway.

So the question is really, can we short cut that somehow?

It does seem like doing so would require a different approach. But so far all our other approaches to creating intelligence have been beaten by the big simple inefficient one. So it’s hard to see a path from here that doesn’t go that route.
Here's mine:

"all and all" is a typo for "all in all" which means "overall", or "taking everything into consideration"

So they are saying the pricing is not bad considering everything it does
Japanese medieval samurai studied zen for the same reason: it gives you the peace of mind, the skill of concentration, and the contact with yourself that help noticeably when you don't have time to contemplate, as in a sword fight. (May have other benefits, too, but this seemed to be the evolutionary selection driver.)

Sugar has extremely well documented negative effects even in the amounts you find in a regular soda (let alone three). Most of the Aspartame studies test massive doses and are generally inconclusive. If it's a choice between the two, go with the Aspartame.
> That means the technology problem is now a money problem.

This is such an odd insight. Most problems in the world can be described as a "money problem", and it's usually the problem that problem solvers are pushing up against.
The problem is that the hills in Seattle are quite large, so you are going up for a long period of time and possibly not able to regenerate before you run out of batteries.

The other problem is that because battery weight is so large, that in itself becomes a limiting factor for hilly operation where it is not really relevant for trolleybuses. And trolleybuses can feed current from uphill buses to downhill buses through the wires, but there's no such connection on battery buses.
That's a strong start, but be careful if your system ever evolves beyond a single logical processor. You'll need additional orchestration to have reliable updates in a distributed system with semi-independent processors. The update on one might succeed, while another fails. Depending on when the old images were produced, the new images might not be able to talk to each other. Depending on their relative roles in the system (e.g. one sets up the power supply or network for the other, or acts as the time master to do certificate validation) this may or may not be an easily fixable issue even if each system locally thinks it's okay.

This sort of functional interdependency has become increasingly common in embedded these days with heterogenous SoCs.

One thing I've seen before is to separate downloading from rebooting, broadcast the manifest for the updates between all the independent processors (all updates need a declarative manifest for so, so many reasons) to check locally, and only proceed when they all agree. Rollbacks are initiated if they can't see everyone with their expected versions afterwards.

Still isn't perfect either.

My spouse is currently subject to a 10-year bar from entering the United States due to an overstay....

We are exploring a hardship waiver (I-601/I-601A) but finding the process challenging while simultaneously managing my business responsibilities.
I've been considering various visa pathways including TN, H-1B, and have begun the I-130 petition process for my spouse.
Given these circumstances:

What strategies would you recommend for addressing my spouse's admissibility issues most effectively?
Are there particular hardship waiver approaches that have proven successful in similar entrepreneurial situations?
Could you advise on the comparative benefits of different visa pathways in our specific case?
Are there any specialized resources or professionals with expertise in cases combining entrepreneurship with complex inadmissibility issues?
Nah it’s just physics, it’s like wheels being more efficient than legs.

We know there is a more efficient solution (human brain) but we don’t know how to make it.

So it stands to reason that we can make more efficient LLMs, just like a CPU can add numbers more efficiently than humans.
I have the same Samsung sound bar and absolutely nothing works. We need to hard reset it every day because it refuses to work, switching between programmes in Netflix causes a horrible loud crack, the latest one is having speakers out of sync. Really bad.

Or you can think that way - you at 36 C radiate 900 W away while from our usual environment you get 800+ W radiated (and also transferred by air) at you (with your body producing that 50-100W difference), and at 280F you’d get only mere watts radiated at you from the environment while you still would start radiating at 900 and going quickly downhill from that as you surface quickly cools down (that is supposing you don’t have some performance enhancing stuff Expanse style to generate 900 watts boiling you blood to bring those 900 watts non stop to the skin) until coming into equilibrium with the environment.
Show HN: Web Audio Spring-Mass Synthesis
Hi, I'm the author of this little Web Audio toy which does physical modeling synthesis using a simple spring-mass system.

My current area of research is in sparse, event-based encodings of musical audio (https://blog.cochlea.xyz/sparse-interpretable-audio-codec-pa...). I'm very interested in decomposing audio signals into a description of the "system" (e.g., room, instrument, vocal tract, etc.) and a sparse "control signal" which describes how and when energy is injected into that system. This toy was a great way to start learning about physical modeling synthesis, which seems to be the next stop in my research journey. I was also pleasantly surprised at what's possible these days writing custom Audio Worklets!

If you insert 150K rows per second, that’s roughly 13 Billion rows per day.

So you’re inserting 10%+ of your database size every day?

That seems weird to me. Are you pruning somewhere? If not, is your database less than a month old? I’m confused.

I'm an American and I was annoyed at how aggressive and militarized the southern border is.

I was on a big road trip across the country visiting national parks. I went to Organ Pipe Nat. Monument in Arizona which literally touches the Mexican border.

On my way there I drove through a border patrol checkpoint 10 miles north of the border inside the US. They don't check southbound traffic, only northbound. I never entered Mexico. On the way back I had to stop at that border patrol checkpoint. The border patrol agent was basically yelling at me for my passport. I told him I didn't have it with me. He yelled to see my driver's license. I gave it to him and he yelled at me "Why do you have a North Carolina driver's license?" I replied that is where I live and that is my home address on the license. He then screamed at me "Don't you know this is a prime drug running area?!" I told him "I have no idea and I'm not interested in drugs. There is a national park area 5 miles away, don't you get a lot of tourists here going to see that?"

I then noticed in my rear view and side mirrors that another agent was going around my car with a dog sniffing around. After about 2 minutes I saw the dog agent give a thumbs up and the rude agent said "Okay, you can go but you should carry your passport"

I had less rude experiences in Texas and California but still overly suspicious border patrol agents. One guy asked me what all the stuff was in my car. I actually offered him granola bars and soda cans and then showed him landscape pictures on my cameras. He realized that I was really a tourist and not into drugs or helping immigrants cross.

It is the stupidest thing to say to someone who is grieving.
It was already disclosed to the bad guys that someone managed to break their encryption, when they didn't get paid and they saw that the customer had somehow managed to recover their data. That probably meant they might go looking for weaknesses, or modify their encryption, even without this note.

Other victims whose data were encrypted by the same malware (before any updates) could benefit from this disclosure to try to recover their data.
None of my headphones have firmware to update. They connect with copper (8000BCE) wires (1830CE) to a 3.5mm jack (1950CE) based on a 1/4" phone plug (1890CE). Some of them use neodymium (1885CE) magnets.

If I want equalization or convolution I apply them upstream shortly after decoding.
It seems that way. The camera on the S24U seems to be a decent piece of engineering which is totally hosed by awful software and a sensor that can't be accessed at full res by third party apps.
It's wild - tariffs meant to shield U.S. interests end up giving Apple and Foxconn headaches, shifting their entire strategy. Reminds me of closing one door only to notice everyone's sneaking in through the window. Protectionism might feel good, but tech always finds another route around.

Holy hell. I just opened one because I got a bug report about a page I maintain, and it was absolutely staggering.

Had I not needed to specifically test Edge on Windows 11, I'd have just pressed and held the power button, then wiped the disk and installed something else if I'd encountered that experience on something I purchased to use for some non-browser-testing productive purpose.

You are seeing the literal downside of strawman criticism, I think? You see the same in most criticisms of "capitalism." If you get to build up the representative as only the negatives of that which you are criticizing, than it is usually a bright flame.

Is extra devious when coupled with what is basically the opposite for all of the supposed "enemies" of that which is being straw manned. Where they are represented by only the best attributes.

And a lot of the deviousness comes from how this makes supposed centrists feel superior in pointing out neither is "true." Which, fair, but where does that take the conversation? It gets dominated by people that rally around the representation they feel invested in and nobody even remembers why it may have first come up in the first place.
Here's the bit that stood out to me:

> Walker said the decision to delay the features was made because of quality issues and that the company has found the technology only works properly up to two-thirds to 80% of the time. He said the group “can make more progress to get those percentages up, so that users get something they can really count on.”

Sounds about right for generative AI running on smaller local models. For consumer tech having it fail in weird ways 1/3 to 1/5 of the time is unacceptable.
>Nearly all complex technical projects are owned by one super smart person (Ex: linux).

By that logic CEOs are super humans too, cuz they own the companies? :D

Investments in AI are now counting by billions of dollars. Would that be enough to create an initial ecosystem for a new architecture?
I believe that so long as weights are fixed at inference time, we'll be at a dead end.

Will Titans be sufficiently "neuroplastic" to escape that? Maybe, I'm not sure.

Ultimately, I think an architecture around "looping" where the model outputs are both some form of "self update" and "optional actionality" such that interacting with the model is more "sampling from a thought space" will be required.
Don't insult tabloids like that. The information content of your average tabloid is much higher.
It's not?

There's a (1**6-1)/1**6 chance of not getting it on any given try, so there's a ~1/10**4 chance of getting it within 100 tries. So quite unlikely, but of course possible and bound to happen among millions of users.
How is the audio compression codec[0] negotiated between the phone and the headphones over Bluetooth? IIRC, Sony supports higher quality codes outside of the standard BT required ones. Is the app required for that negotiation or is it all in the operating system now?

How hard can it be? Models like Deepseek R1 are state-of-the-art and open source. Apple could just take one of these, tune it, and put a nicer user interface on top of it.

Sure, maybe it is embarrassing for Apple that they haven't made their own model, but the price of LLM AI is dropping like a rock, and eventually, Apple's large user base, distribution, UI design, and convenience will win the day.

I'm not deep researcher, more like amateur, but could explain some things.

Most problem with current approach, to grow abilities, need to add more neurons, but this is not just energy consuming, but also knowledge consuming, mean, at GPT-4 level all text sources of humanity already exhausted and model become essentially overfitted. So looks like multi-modal models appear not because so good, but because they could learn on additional sources (audio/video).

I seen few approaches to overcome problem of overfitting, but as I understand not exist universal solution.

For example, tried approach to create from current texts some synthetic training data, but this idea is limited by definition.

So, current LLMs appear to hit dead end, and researchers now trying to find exit from this dead end. I believe, nearest years somebody will invent some universal solution (probably, complex of approaches) or suggest another architecture, and progress of AI will continue.
Try to actually use a recent version. Never had a problem with late plasma 5 and recent Plasma 6 on Arch.
Yes. Fantastic little software. Even though It has a filter for subsystem, I couldn’t figure out how to add predicate (like in Ulbow)?
One thing that I find very interesting is that in the past year Apple marketed new iPhones mostly through its supposed AI features while consumers in two major markets (EU and China) can’t use these features. It appears like Apple hastily tried to jump on the AI bandwagon without having a real strategy.
Oh yeah, that's exactly what I was thinking of! Seems like it would be very useful for expert models with domains with more definite "edges" (if I'm understanding it right)

As for the fragmentation of progress, I guess that's just par the course for any tech with a such a heavy private/open source split. It would take a huge amount of work to trawl through this constant stream of 'breakthroughs' and put them all together.

5,000 users PER DAY is trivial sauce, you're totally worrying about something ridiculous. Even a crap server with crap code should handle that.

BTW most databases on a decent server could totally handle that 1 million IoT updates per day too. 1 packet per day is nothing. Unless they all come at once. That is also a fairly trivial load, if it's spread out. A small VM could handle that.

You are way off on your understanding of what is a heavy load.

You could load test with something like k6 if you want to find out. Try 'emulating' the requests and average users.

I often test with 5,000 requests per second, 5,000 users per day with 20-30 requests each is several orders of magnitude less load.
Heh, no chance I can introduce this at work and hard to have a personal project requiring it. :)

I think you probably need some documentation to the effect of the current state of affairs, as well as prescriptions as to how to work around it. _Most_ live workloads, even if the total dataset is huge, have a pretty small working set. So limiting DB operations to simple fetches and doing any complex operations in memory is viable, but should be prescribed as the solution or people will consider it's omission as a fault instead of a choice.
No worries, I agree with you in principle and for my own usage but, in practice I don’t want my grandma to have to think about security at all and I’d prefer if there were very few ways she could be social engineered to circumvent what security is there.

Beyond that I think total control can still be achieved in the realm of hobbyists who can run Linux or flash alternative firmwares etc.
I feel like some hallucinations aren't bad. Isn't that basically what a new idea is - a hallucination of what could be? The ability to come up with new things, even if they're sometimes wrong, can be useful and happen all the time with humans.
