Analemma_'s comment made it sound like some broad and well-studied thing. All I've seen is mention of a single city. This is not remotely enough to support the claim.

My claim was based on skimming an article that said fares ranged from about 10 to 50% of funding and I speculated that most probably tended toward 10% since most are small, and small ones depend on federal funding, special purpose taxes (Georgia has a lot of SPLOST[0] projects), and partnerships.

Smaller systems suffer from low ridership and might see more benefit from dropping fares. A full bus and an empty bus cost about as much to run, but a system of full buses is easier to bolster and improve because more people will support it.

And I don't see why this would be connected to behavior on buses and trains. Where is this research? At least for Seattle since everyone wants to focus on it for some reason. News articles for a single city are not research.

For a very long time information was and still is passed on via oral history in the form of stories and songs. I'd even guess that is what religion is just ancient stories of people trying to figure out who we all are and how we got here.
> "Is the CPU really that serial, when it literally reschedules your instructions based on the graph of their interconnections?"

Yes. Yes, it is because all of that rescheduling and reordering is completely hidden at great effort and expense to make it seem like the instruction stream is executing in exactly in the order specified. If it weren't, lines of code would essentially execute in an indeterminate order and no programs would function.
> Agree with 1. Ban AirBnB. (this is already in play as I understand it)

I believe no new licenses are being granted. Personally, I don't think this goes far enough. Revoke existing licenses.

> The Golden Visa scheme is a nonsense (I think this is also being scrapped)

IMHO this was an overreaction. If the issue was pricing out locals, you could simply remove real estate as a qualifying investment under the visa and/or increase the minimum investment amount.
Seattle government and area transit agencies is pretty bad at this kind of thing. If they say 2023, they probably mean 2025 or later.
Use compressed air or NOx as oxidizers for delayed combustion in engines. Not only would it provide a means of storing energy for ICEs, but it would also eliminate pumping losses on the intake stroke.

Actual suffering mentioned in that hour-plus long interview: None.
I have many similar projects. By far, the hardest part for anything I actually want to share is user friendly wifi provisioning. The rest is easy, displays, devices and power supply. (I have 5 different HL-tech radars on boards with 3 different displays, one using LVGL).

I am using the app based Espressive app based provisioning now and it's the best of the lot but still flakey on the Risk V chips like much of the IDF/Arduino wrappers. It's a hard problem.

Most of it works pretty well with the Extensa core so I suggest sticking with those.
Obviously would like to be able to enter my zip/postcode and get a list of links to tool/thing libraries local to me. Does this exist already? Googling it seems like these are few and far between except some hardware/auto parts stores will lend some tools, and there are commercial tool rental places for a fee. I once borrowed a post hole digger on Craigslist, and lent a stapler on Facebook.
There is a reply at the end stating it works with 48GB DIMMs too.
Yeah. So Bluetooth never uses mp3 for transmission as far as I am aware - it is simply not one of the codecs specified in the protocol.

So why does that decoding chip have mp3 decoding, and why use mp3 when you could just use SBC.
> Could it be that the dissociation is the cost, not the cause?

I don't know. I know that the dissociation mostly developed as an attempt to escape from reality... my theories on this range from "I just really liked computers" to "autism and ADHD ripped away so much control over my body that I don't even want to try to control my body anymore, I just want to be an internet creature". It doesn't have much to do with the simulations, it just makes them better since I have the ability to dissociate, I guess.

I will admit you're right, though, about me putting myself in the position of others. I can feel exactly what I would feel if I were there, in that exact moment. Because, in a way, I sometimes am. Since the mind is a complex thing and all that. I'm constantly in multiple places at once, not physically or spiritually, but mentally. It happens when I'm having multiple conversations at once, it happens when I'm context-switching between multiple situations at once, it happens when I'm having cognitive dissonance, and that's not even counting the situations where there are actual other personalities active at the same time because dissociative identity disorder really is a giant clusterfuck.
Wouldn’t Google be able to catch up easily if that was really OpenAI’s only advantage? Google has a lot more resources to throw at RL. It seems like there must be some other secret sauce for OpenAI to continue maintaining such a huge lead.
We are decades away from needing this. But we need to generate ammonia without fossil fuels for fertilizer and feed stock.

Also, we need a fuel for long distance transport like ships when batteries won’t work. Ammonia will always be cheaper than synthetic fuel because no carbon doesn’t have to come from air, and it stores better than hydrogen.

There may be lots of surplus electricity in the future but there will also be a lot of demands for carbon capture, hydrogen, long term storage, and chemical processes.
Your overall understanding is correct. People pay DocuSign to "think" of everything for them (which is not at all bad, it just comes at a cost). Depending on the space, you have to deal with crazy laws that no one in their right mind would know about (nor think to even consider).

Essentially, "no one ever got fired for signing with DocuSign" (play on IBM).

I'm late to the party here, but if the authors want real world examples, please reach out.
It gets the people going!
Sometimes it bothers me when we jump to the conclusion that anything “green” is a compliance and PR move and not as a viable profitable business.

Products like EVs and solar panels aren’t just some hypothetical niche anymore.

An energy company that sells fuel for cars and electrical generation having a business segment that sells energy for electric cars seems like a very relevant and complementary business.

Maybe it is just for PR but it seems like BP would have a leg up on making a profitable charging network.
I very much want to build a N100/N200 cluster. The Asrock N100DC-ITX board is almost there, but they missed with only one on-board realtek NIC.

Perfect would be mini-itx N100/200, two M.2 slots, two Intel 2.5 GbE NICs, 16/32 GB RAM, a fanless heatsink and DC powered. Don't care much about anything else on the board; 3x USB and whatever video is cheapest is all that's needed.

The N100/N200/N305 parts only have 9 PCIe lanes, so one of the two M.2s would need to be cut back to 2x lanes (call that the boot device, whatever.)
> Is there a technical reason for it like causing interference or something?

That's correct, more or less.

There's this thing called "frequency shift keying" (FSK) which was the de facto standard digital modulation technique at the time the regulations were created. With FSK, you transmit data by toggling back and forth between two frequencies. That abrupt jumping back-and-forth creates hellish interference for people trying to use nearby frequencies.

Today, the obvious solution is to limit bandwidth so that there's a healthy amount of space for people to avoid that interference. However, in a (1970s/1980s) world where FSK is the only widespread modulation scheme, that wasn't really the mindset. The way they saw it was simpler: "higher baudrates demand more bandwidth, and more bandwidth creates more interference." Thus, they regulated baudrate as a means of regulating bandwidth.

The impetus for the rule change is simple: we have better modulation techniques nowadays. In case I haven't bored you to death, the simplest one to explain is probably GFSK. It's similar to FSK, but instead of abruptly jumping between the two frequencies, you gradually slide back and forth between them (the "G" stands for Gaussian). GFSK requires more precise electronics, but it doesn't cause as much trouble for people trying to operate at nearby frequencies. There are countless other modulation techniques as well. Bluetooth is probably the most notable implementation of GFSK (though modern Bluetooth actually uses something else).

For completeness: FSK is very useful and it's still widely used today. Your garage door opener uses it, among other things.
I think he must have lived near me in Silver Lake. I occasionally saw him when we were both out for a run. After a while he recognized me, and he'd smile and wave. The hill was steep, and I remember him struggling, but the way he smiled, he clearly had a sense of humor about it. I could see he was determined. Although I never talked to him, from our very limited interaction he seemed like a nice guy. This news makes me sad. RIP.
Nope. Anhydrous ammonia between 18-25% is literally ‘explodes like gas vapor’ type explosive/flammable.

It does have a higher ignition point than gas. But one a spark can definitely reach. It’s been a common problem in industry where ammonia gets used a lot (refrigeration in particular).

BLEVE’s are also a problem too of course. And the toxic nature of breathing it in! Haha.
Yeah, “properly” was doing some work in my response :) It helps to use a glossy paint, and to put that over wet-environment primer on top of wet-environment drywall.
It seems like a city with a ~$2 trillion economy could afford to fund the transit system that enables it without fare boxes.
My pointers are:

1. Learn the rail system and how to navigate it with the Japanese railway apps on a smartphone. I have seen too many tourists with looks of bewilderment at train stations trying to get somewhere.

2. Make every hotel reservation in advance. Most hotels here will not accommodate a person who shows up even if they have rooms available.

3. Most areas of Japan use different commuter passes so check ahead to see if you need a different pass for bus/trains.

4. Trains are nice but if you miss one you could be in a big wait or be later than you expected.

5. If you’re in the countryside you’ll be walking more or taking a taxi to get somewhere.

6. You may want to get used to ramen, soba and tempura as most of the near by restaurants will be offering this.

Aside from all this just enjoy the clean air and the view.

figure out the computational stable state of society

Hahahaha!! That's so "psychohistory" ... it suggests such, almost 'individual'-like intention.

Also, none of it has failed. That's an absurd interpretation of where we are. The real problem is that everything we do ... all the day-to-day problems we solve, all the systems we build that fit and do a 'good job' helping us, say, in some respect, ... set us up to need even more of the same basically. As you wrote elsewhere ... increasingly complex etc.

I'd flesh out more, but, must run now.

The reality is simply that we WON'T outrun reality. There is no failure, nor is there success ... that dualistic thinking really tends to obscure rather than clarify ... by anchoring some 'conclusion' based on some specific perspective and cutting off wider views. We will follow 'the laws' of other organisms ... our own specific path, but the same basic fundamental arc ... game theoretic and in less ... abstract framings.

I followed Jordan's Birmingham baseball run and I thought he showed a lot of promise.
Israel didn't bomb a hospital, that was a misfire of their missile. Israel showed that a different hospital is actually used as a base of operations for the Hamas because they know Israel won't bomb it.
Without diminishing Mathematica/WA, have any of his ideas produced tangible, actionable results post-1990?

It's a serious question rather than snark as I am only moderately familiar with his work. I appreciate some of his thoughts (ex: computational irreducibility), but I feel like I've got at least 20 years of asking "So what?" when he publishes. And yet here we are, discussing him, again.
Obscuring a message, by itself, does nothing to prevent MitM attacks. If you're worried about message integrity on the amateur bands, the rules do nothing to prevent the use of digital signatures.
In many US states, $100-150 per year is typical.
Diesel is definitely flammable. I works great as an accelerant.

It isn’t as easily flammable as gas, and doesn’t have easily autoignitable vapor like gas.

I’m guessing you dumped a lot of it on something without a lot of thermal mass?

If you did the same on a bonfire, you’d have a different story.

Ask HN: How long does Amazon delivery typically take?
I mainly used Amazon Prime for streaming, and now it's all ads so I'd like to cancel it. I live in various places, but all major US metropolitan downtown areas and I have this sneaking suspicion that I'm not actually benefiting from Prime 2-day free either since they're doing dropoffs at my various apartments all the time. If I cancel Prime will they start to pour molasses on my orders? (also, I'm sure people who don't match my profile will have interesting things to ask or say, so don't limit yourself, but I'm not talking about backordered or 3rd party fulfillment)

It's that awkward time when it really dawns on you that mortality is really a thing. Prior to that you feel very far removed from it, so it isn't much concern.
Lawyer here. Not legal advice. Really not that much by way of law to consider. If everyone agrees that an E-signature is good, then, generally speaking, an e-signature is good. I’d suggest it’s more on the people actually drafting the documents being signed than the software layer facilitating.
Not to mention the dissolved solids as well, so it's not as simple as using tap water.

IMHO Celsius is the SI unit least deserving of praise. It's just bolted onto the system through the Boltzmann constant and isn't intricately linked like other SI/CGS units. It's also a little too coarse for modern use. Sure, I could use decicelsius myself, but that doesn't stop every other weather station, AC/thermostat manufacturer, etc. from still using whole degrees. You can buy $2000 Italian espresso machines with elaborate PID controllers that can only be tuned to whole degrees, which ironically means that using Fahrenheit is more precise!
It's surprising to see the smaller SKUs that are available for z16s, given how we think mainframes are monsters: the smallest is a 18U bring-your-own-racks-and-power-distribution model.

(It's also interesting that PCIe 3 is the glue bus between compute units and their own bespoke peripheral connection technologies...)
Most projects I decide not to pursue is that is blatently obvious that making a profit ffom them will be near to impossible.

But I have finally found an idea that is worth pursuing but I am doing that on my spare time so development is slow.Not really what you were asking but several of my projects died because I didnt have time enough for them. Im fine with that though since the competition is pretty much none, sucks and is expensive as hell. Seems like the perfect market, but we'll see.
Hey! Glad to be an inspiration :)
For a project that deals with signatures it should be pretty obvious that this does not quite work in a legally sound way. At least in the PR they will need some prove that I acknowledge to have read this Contributing.md. They is a reason why people go through the hassle of CLA signing flows. Wonder why they do not dog food their own system.

Israel is far from blameless in the rise of Hamas. Especially Benjamin Netanyahu who as an Israeli I would love to see go to trial for supporting Hamas (in addition to his other ongoing corruption charges).

Still, there are levels of blame and the current situation. The Palestinians in Gaza are held hostage by an evil organization that keeps escalating and using ceasefires to increase armaments. I would love it if Netanyahu would be out of office right now and someone "competent" were running things. But this is the position we're at.
Native apps were open-sourced yes in the repo, but the community moved them out into their own repos and archived them. Hard to build native apps open-source with all the tooling, and the community has been working on replacing them with a webapp
If you think the front-end is a mess just wait to till you see the layers upon layers of complexity people are using the manage back-end services.
I enjoy Shawn Woods's channel, but I'm skeptical of his claim that he's barely breaking even on videos. His production costs seem to be nearly zero, and he makes YouTube ad money from 2M subscribers, and most of his videos are a review of a product for which he's a paid affiliate.

I feel like the flaw in the Dizzy Dunker is that you can't just look in to see if it caught a mouse. You'd have to physically remove the top every time or use a translucent bucket.

With the simpler walk the plank or rolling log traps, you can see at a glance whether the trap caught a mouse.

Thanks, this appears to be useful for end of life as well.

Problem is GP's really dont like being challenged in my experience, and its a case of having to write papers to challenge their theories with more recent (< 30yrs) scientific discoveries and studies. In other words, I'd have to throw more recent expert stuff back at them, which is an exercise I dont have time for, but when banged up the movements are seriously curtailed, and access to the internet is seriously restricted to non existent, making it impossible to fight back once inside. Its a Kobayashi Maru in Star Trek terms!

Their medicines are shrouded in secrecy in the main, which also makes their judgements harder to fight.

When inside you dont even get a patient information leaflet for the meds they "prescribe", its effing dictatorial, Josef Mengele would be proud of the british state today!

Dont get me started on the patronisation by staff either!
I’m not an engineer, but I’m not sure I understand why there is any fixed surface area once the mice enter the opening.

That is, why isn’t the hole in the surface of the trap a rectangle (the shape of the cover) instead of a hexagon (the shape of the paddle)?

That one mouse (out of 101 mice) that got away was only able to do so since there was a non-spinning surface for it to grab on to.

Unless I’m missing something, it seems like a simple solution would be to just make the opening a rectangle, so that once they entered, the only surface they could walk on was the spinning paddle.

I’m not sure why the inverter — or the production engineers — didn’t think of that. But again, maybe I’m oversimplifying it.
Notice that it's the goal only on the moment of the armed invasion which happened only yesterday. The line goes through Israel and it could have cut that on day one.

Cutting communications before an invasion is pretty basic military strategy. Unfortunately, it also cuts civilian population off but as we asserted... The Hamas is embedded in civilian population and uses them as human shields. It steals fuel destined for hospitals and has made itself rich over the backs of the Palestinian people.
For sure - definitely doable, and certainly not the worst industrial chemical used at large scale. But not super consumer friendly.
Hey! I'm James, the original creator. Yeah, I tried to stay involved but over time I had to accept that my life right now just doesn't allow time to be very involved. We've had some incredible maintainers step up and their doing an amazing job stewarding the project along.

I'm long-overdue to check in with the maintainers and write some content about the transition. I was also intending to shutdown the hosted version late summer and hand over actualbdget.com to the open-source community. My goal is to do this by end of year.

Overall, I wish my life weren't so busy in some ways, but it's busy with really good and fulfilling things. The transition was a little rough for me (hard to give control away of something I worked so hard on) but it's turned out surprisingly good
I don’t agree. "Stop this newfangled bullshit and let's go back to the way things used to be" is a very common political message.
A lot to unpack here...

* Why is it receive-only?

Like an antenna, a Rydberg sensor can detect incoming radio signals. Otherwise, the underlying physics are completely different. If there's a way to make it transmit, I've never heard of it.

* What is the difference between a Rydberg atom, an Ion trap, and a Quantum Dot?

These are all unrelated devices with different underlying principles.

* How many 4 or 2 Mhz antenna/transceivers are necessary to sufficiently cover a 0 to 1 Ghz band? What about to cover 1 Thz: (terahertz) band(s)?

It depends what you mean by "cover".

Rydberg sensors are tunable over a huge range, typically quoted up to 20-40 GHz. So one sensor would "cover" the whole range of you're willing to wait.

(I don't know what currently sets that upper limit, but what are you doing that needs more than 40 GHz? Electronics capable of handling such frequencies are rare, specialized, and expensive.)

That said, the instantaneous bandwidth of a Rydberg sensor is low, typically around 1 MHz. So if you want to "cover" the whole 0-1 GHz range all at once, I'd start from a different approach.

* How should they be placed in spacetime to minimize signal loss e.g due to crosstalk and cost?

No idea. Each Rydberg sensor requires a lot of expensive support equipment, including two or more precisely tuned lasers.

What are you trying to do?
This is really useful! Using LLM-assisted evaluation seems like the way to go for evaluating RAG applications. One issue I've faced while evaluating responses using GPT-4 is that the evaluation cost can go out of hand rather quickly. Do you have any measures in place or ideas on how to handle this?
