Show HN: Dog Rescue Transport Coordination Website
by josdijkstra | 2025-09-06 23:43:18+00:00
Recently, I was part of a dog rescue transport from Denver to Frisco, CO, and it opened my eyes to a major problem: coordinating volunteers shouldn't be this complicated. Between fragmented communication (Facebook, phone calls, emails, texts...), missing handoff details, and manual route planning, I wanted to work on a better solution.

Meet puptransfur.org - purpose-built to make rescue transports seamless and paw-fect. Easily plan routes, coordinate handoffs, manage timezones automatically, and document the journey with photos. Use the demo option to create your own route, or look at an example route: puptransfur.org/route/4041

If you are part of a dog rescue and need to organize dog transports frequently, would you want to use this website? Let me know and I can guide you through the first steps and show how everything works.

Some features: - address completion when setting up the route - suggested handoff locations to easily break up the route into multiple segments - handles timezones by adjusting the times to local times - volunteer information available to other drivers (car model and color, license plate, if available) - integrated email communication when drivers sign up, and when drivers are confirmed

And the best feature I think is this one: this site can bring all volunteer drivers of all rescue organizations together in one place!

This website is free to use for administrators of dog rescues as well as for volunteer drivers. I'd love to get some feedback on this. Thanks for looking!

It's not at all trivial to build a "small but highly capable" model. Sacrificing world knowledge is something that can be done, but only to an extent, and that isn't a silver bullet.

For an LLM, size is a virtue - the larger a model is, the more intelligent it is, all other things equal - and even aggressive distillation only gets you this far.

Maybe with significantly better post-training, a lot of distillation from a very large and very capable model, and extremely high quality synthetic data, you could fit GPT-5 Pro tier of reasoning and tool use, with severe cuts to world knowledge, into a 40B model. But not into a 4B one. And it would need some very specific training to know when to fall back to web search or knowledge databases, or delegate to a larger cloud-hosted model.

And if we had the kind of training mastery required to pull that off? I'm a bit afraid of what kind of AI we would be able to train as a frontier run.

SPF 50 blocks 25% more UVB than SPF 40 does. Measuring it as percentages makes it non-linear in a way that most people find confusing. Imagine we had one sun cream that blocked 99.9% and another that blocked 99.5%. Sounds like nothing; only an 0.4p difference, but is actually 5 times as effective.

You're right about how long it lasts also being an important factor. UV-A protection is also another very important factor. But as someone with pale skin even by Scottish standards, the difference between SPF 40 and SPF 50 around noon is significant, even through I consistently re-apply every hour. I won't get burnt, but I'll end up with more sun damage - and that lasts until late autumn.

I don't really need AI in my browser. I do like spaces in Arc, and how it handles cleaning up my tabs. The color coding of the sidebar for the various profiles is the one feature I haven't been able to find in things like Orion, Vivaldi, Firefox, etc. By color coding, I mean the ability to make the entire sidebar a different color, which helps me make certain I don't do stupid things in prod.

Determining a statement's truth (or if it's outside the system's knowledge) is an old problem in machine intelligence, with whole subfields like knowledge graphs and such, and it's NOT a problem LLMs were originally meant to address at all.

LLMs are text generators that are very good at writing a book report based on a prompt and the patterns learned from the training corpus, but it's an entirely separate problem to go through that book report statement by statement and determine if each one is true/false/unknown. And that problem is one that the AI field has already spent 60 years on, so there's a lot of hubris in assuming you can just solve that and bolt it onto the side of GPT-5 by next quarter.

>why not just use LIDAR that can literally see around corners in 3D?

LIDAR requires line-of-sight (LoS) hence cannot see around conner, but RADAR probably can.

It's interesting to note that the all time 2nd most popular post on Tesla is 9 years ago on its full self driving hardware (just 2nd after the controversial Cybertruck) [1].

>Elon's vision-only move was extremely "short-sighted"

Elon's vision was misguided because some of the technologists at the time including him seem to really truly believed that AGI is just around the corner (pun attended). Now most of the tech people gave up on AGI claim blaming on the blurry definition of AGI but for me the truly killer AGI application is always full autonomous level 5 driving with only human level sensor perceptions minus the LIDAR and RADAR. But the complexity of the goal is very complicated that I really truly believe it will not be achieved in foreseeable future.

The difference is liability. If you're riding a Waymo, you are not at all liable for what the vehicle does. If there is a collision, you don't need to exchange your insurance info or name or anything else (regardless of who is at fault). You are not allowed to be in the drivers seat.

Tesla has chosen to not (yet) assume that liability, and leave that liability to the driver and requires a driver in the drivers seat. But someone in the drivers seat can override the steering wheel accidentally and cause a collision, so they likely will require the drivers seat to be empty to assume liability (or disable all controls, which is only possible on a steer by wire vehicle, and the only such vehicle in the world is Cybertruck).

Tesla has not asked for regulatory approval for level 4 or 5. When they do, it'll be interesting to see how governments react.

I think it’s a bit of both. It’s very important to struggle with a problem yourself. You need your brain to be thinking about it, turning it over, at least for a bit.

But when you’re new on a topic, it can take hours to nail the solution by yourself. I’m thinking of science & math practice problems. If you skip ahead to look at the answer, you can use it to work backwards, to understand where you were struggling and going wrong.

Crucially, you’re not just copy/pasting the answer. But taking this “shortcut” early can definitely be helpful. It’s very easy to spend a lot of time going down the wrong path. If you can take the shortcut when you sense that’s happening, and really try to understand why that wrong path isn’t right, I think the shortcut can help speed you up.

I think the same applies with LLMs. It’s important to not just have the LLM do it all from the start. But when you start getting stuck, having it give you recommendations is a good way to get tutored, so long as you’re really thinking about it.

Harvard study: the science is inconclusive and more research is needed.[1]

News outlets: no credible scientific evidence.

Uh oh spaghettios. The more the leftwing "resists" the more their "science" self-image will disconnect with reality. Like most things with this administration, I think that's the real goal.

It's an underwhelming product in an annoying market segment, but 256GB/s really isn't that bad when you look at the competition. 150GB/s from hex channel DDR4, 200GB/s from quad channel DDR5, or around 256GB/s from Nvidia Digits or M Pro (that you can't get in the 128GB range). For context it's about what low-mid range GPUs provide, and 2.5-5x the bandwidth of the 50/100 GB/s memory that most people currently have.

If you're going with a Mac Studio Max you're going to be paying twice the price for twice the memory bandwidth, but the kicker is you'll be getting the same amount of compute as the AMD AI chips have which is going to be comparable to a low-mid range GPU. Even midrange GPUs like the RX 6800 or RTX 3060 are going to have 2x the compute. When the M1 chips first came out people were getting seriously bad prompt processing performance to the point that it was a legitimate consideration to make before purchase, and this was back when local models could barely manage 16k of context. If money wasn't a consideration and you decided to get the best possible Mac Studio Ultra, 800GB/s won't feel like a significant upgrade when it still takes 1 minute to process every 80k of uncached context that you'll absolutely be using on 1m context models.

First, one shouldn't use a moved-from object in the first place (except for, maybe, reassigning it).

Second, why can't the .street() method simply return an empty string in this case?

> The moved-from value has to be valid after move (all of its invariants need to hold)

The full quote from the C++ standard is: "Unless otherwise specified, such moved-from objects shall be placed in a valid but unspecified state" AFAIK, it only makes such requirements for standard library types, but not for user defined types. Please correct me if I'm wrong.

Broadcom does custom silicon design as well [0]. If a company like Google or Microsoft wants their own custom ASICs to train models on, they tend to work with Broadcom to design 'em.

This is something Nvidia has been historically bad at. It's basically Broadcom and Marvell that own the custom silicon segment.

this might be a good thread to ask this as i cant get a straight answer from apple forums - i have a relatively recent iPad that was bricked after i updated to iPadOS 26 dev beta and then didnt like it and downgraded - now it simply wont turn on. its out of warranty so apple doesnt care/doesnt help - but i know the hardware is just fine.

what can i do with it? i'm willing to disassemble it but i have no idea where to start on what's wrong; all i know is itd be a waste if i just threw this in a trash.

I speak Chinese :)

It's a mixed system with about 2 millennia of legacy. It started as logographic, then it got into phono-semantic compounds, with detours into the written-only official language (like Latin), and now it's messy mix of everything. There are true logographs (休，林，森), true phonosemantic compounds, and plenty purely phonetic characters that have no meaning by themselves ("bound morphemes").

The article is focusing a lot on the behavior of the automakers not paying thier suppliers in a “timely” manner. I don’t think they realize that 60 days to pay a supplier in the US auto industry is not common.

Cashflows for a new supplier to a US automaker don’t start for 12 months. Think about that. The business has to float 12 months of operational expenses before it receives its first payment. If you can make it then business is pretty reliable.

Without questioning this idea on political grounds, I am not sure if it would be at all possible for an Ascend 910C cluster to enter the supercomputer rankings. I could not find a public datasheet on this chip (would appreciate a link), but my impression is that it is an AI accelerator that does not target FP64, whereas TOP500 is looking at HPC (FP64) performance [1].

That doesn't matter - it cost a billion dollars to write the current project I work on. There is no way I can ask for that much to rewrite it all in whatever. Thus we are stuck on c++ which was the best choice 15 years ago. Anything that makes new code easier to write is great help.

sure we are looking at options - but rust and c++ don't interoperate well (c api is too limiting). D was looking interesting for a while but I'm not sure how it fits (d supports c++ abi)

> As a long time user of C++, I want to propose a question: do we think C++ will ever reach a point where it is significantly ergonomic and safe enough to use (in comparison to e.g. Python or Rust) via adding new features?

Memory safety semantics aside (needed and will be disruptive, even if done gradually) ---

You could get 80% of the way to ergonomic parity via a 1:1 re-syntaxing, just like Reason (new syntax for OCaml) and Elixer (new syntax for Erlang). C++ has good bones but bad defaults. Why shouldn't things be const by default? Why can't we do destructuring in more places? Why is it so annoying to define local functions? Why do we have approximately three zillion ways of initializing a variable?

You can address a lot of the pain points by making an alternative, clean-looking "modern" syntax that, because it's actually the same language as C++, would have perfect interoperability.

Garbage. An audit reviews a trail of origin. Tether got an attestation, that said no more, and no less than, "At this exact moment in time, the balance in this account is $X". You could take a short term loan for the majority of that and no-one would know.

You and I can't buy a house on a mere attestation of accounts - funnily enough, lenders want to see how we acquired that money. But these clowns can stand on stage at Davos and say "Yeah, we've banked over half a billion a day USD for the last two years, trust us, we don't need an audit". I know that comparing investment to revenue is not apples-to-apples, but to get an idea of what that incoming cash looks like? You're on the scale of Saudi Aramco. Samsung. Alphabet.

They kept firing their auditors. They had one done, and then refused to release it, saying "it was not of use to anyone because it was in Mandarin Chinese". What the actual fuck?

Their bad rep is their own fault.

"Tether and Bitfinex are completely independent and unrelated!" Oh yeah, why are the same two people who signed a loan contract on Tether's behalf ... the same two people who signed it on Bitfinex's behalf?

Or let's look at their bank, Deltec, who also made statements to "support" Tether... or specifically, let's look at some of the highlights from a fucking trainwreck of an interview their "Deputy CEO" gave to CNBC:

- was conducted from his gaming rig

- about Deltec's (and therefore Tether's) money movements being several times larger than all the banking in their country was due to people misunderstanding the country's two banking licenses, the names of which HE "couldn't remember right now" (the Deputy CEO of a bank who can't remember the name of the banking licenses where they operate?!?), and he "wasn't sure which [banking license] the bank has, but we might have both"

- oh yeah, said Deputy CEO's "resume": 33 years old, by his LinkedIn claimed to have graduated HEC Lausanne in Switzerland with a Master of Science at the age of 15... celebrating his graduation by immediately being named Professor of Finance at a university in Lebanon. While dividing his spare time between running hedge funds in Switzerland (called Indepedance [sic] Weath [sic] Management) and uhh... Jacksonville, FL.

Once CNBC's viewers started ridiculing and questioning both Deltec Bank and Tether, said Deputy CEO was hastily removed from Deltec's "Leadership Team" page on their website. Once that was questioned, he was re-added...

... and then the entire bank website was replaced with a low-effort WordPress template. Their online banking was Javascript hard coded to refuse all login attempts.

"Sounds legit to me", say the crypto bros.

Nice! Cheap RK3588 boards come with 15GB of LPDDR5 RAM these days and have significantly better performance than the Pi 5 (and often are cheaper).

I get 8.2 tokens per second on a random orange pi board with Qwen3-Coder-30B-A3B at Q3_K_XL (~12.9GB). I need to try two of them in parallel ... should be significantly faster than this even at Q6.

The FDA listed 12 typical sunscreen ingredients, such as avobenzone, octinoxate, and oxybenzone, as not currently having sufficient data to be recognized as safe and effective. They're absorbed into the bloodstream and studies have found them to persist for weeks

Based on current data, the FDA categorized only two sunscreen ingredients as safe and effective, the mineral-based ones: zinc oxide and titanium dioxide, which don't permeate the skin much.
by ghosty141 | 2025-09-06 23:59:09+00:00
Absolutely spot on in my opinion.

Also things often just don’t compose well. For example if you have a nested class that you want to use in an unordered_set in its parent class then you just can’t do it because you can’t put the std::hash specialization anywhere legal. It’s just two parts of the language which are totally valid on their own but don’t work together. Stuff like this is such a common problem in c++ that it drives me nuts

Your Top 500 link says something completely different:

"The 65th edition of the TOP500 showed that the El Capitan system retains the No. 1 position. With El Capitan, Frontier, and Aurora, there are now 3 Exascale systems leading the TOP500. All three are installed at Department of Energy (DOE) laboratories in the United States."

HPC6 is listed below those, and far less powerful.

It's not "safer" from the sun, but could be safer from side effects of the chemicals used in typical sunscreen.

The FDA listed 12 typical sunscreen ingredients, such as avobenzone, octinoxate, and oxybenzone, as not currently having sufficient data to be recognized as safe and effective. They're absorbed into the bloodstream and studies have found them to persist for weeks.

Based on current data, the FDA categorized only two sunscreen ingredients as safe and effective, the mineral-based ones: zinc oxide and titanium dioxide, which don't permeate the skin much.

"Although the protective action of sunscreen products takes place on the surface of the skin, there is new evidence that at least some sunscreen active ingredients are absorbed through the skin and enter the body. This makes it important for FDA to determine whether, and to what extent, exposure to certain sunscreen ingredients may be associated with any safety risks. FDA has requested data from industry to confirm the safety of sunscreen active ingredients."[0]

> cost & timeline

It's really hard to accept cost as the reason when Tesla is preparing a trillion dollar package. I suppose that can be reconciled if one considers the venture to be a vehicle (ha!) to shovel as much money as possible from investors and buyers into Elon's pockets, I imagine the prospect of being the worlds first trillionare is appealing.

Cal Newports Slow Productivity has a lot to say about this topic.

Creativity comes in bursts and can’t be scheduled. Happiness and health move with the seasons. Treating humans as divisible units of 1 hour blocks of factory farmed ROI will never yield amazing results.

It’s sad to see the more technology and automation we invent the more we become slaves to the cult of pseudo-productivity, virtue signalling hours at work in place of meaningful output or results.

Well, Each Channel needs a lot of pins. I don't think all 288/262 pins need to go to the CPU, but a large number of them do, I'd wager; The old LGA 1366 (Tri-Channel) and LGA 1151 (Dual Channel) are probably as close as we can get to a simple reference point [0].

Apple FBOW, based on a quick and sloppy count of a reballing jig [1], has something on the order of 2500-2700 balls on an M2 CPU.

I think AMD's FP11 'socket' (it's really just a standard ball grid array) pinout is something on the order of 2000-2100 balls and that gets you four 64 Bit DDR channels (I think Apple works a bit different and uses 16 bit channels, thus the 'channel count' for an M2 is higher.)

Which is a roundabout way of saying, AMD and Intel probably can match the bandwidth but to do so likely would require moving to soldered CPUS which would be a huge paradigm shift for all the existing boardmakers/etc.

[0] - They do have other tradeoffs; namely that 1151 has built in PCIE, on the other hand the link to the PCH is AFAIR a good bit thinner than the QPI link on the 1366.

I heard an interesting talk recently by a Stanford neuroscientist.

He was studying standing waves of brain activity among circularly linked groups of neurons. Neurons can provide both excitatory inputs and inhibitory inputs to other neurons.

For a computer programmer, it is easy to imagine excitatory and inhibitory localized phenomena giving rise to all sorts of interesting and complex self-sustaining standing waves.

Think of the study of cellular automata by Stephen Wolfram and others, in which various simple localized rules give rise to all sorts of interesting computational phenomena, up to and including Turing Completeness.

In animal models such as pigs, these standing waves can be observed to persist for months if not longer.

His particular area of interest is to subject the brain to gentle sub-lethal doses of radiation treatment in order to change selected standing waves.

My thought is that there may be a qualitative difference between the underlying "neural hardware" and the thought processes that "execute" on this hardware.

It is the bread and butter of computer scientists to reason in a world in which the complexity of software greatly exceeds the simple computational artifacts on which it runs.

One might say that chess has information content that is qualitatively dissimilar to the wood-working needed to make a pretty chess board.

The information content in DNA is composed of chemically interchangeable A, G, T, and C molecules. So, one might say that the underlying physics is "walled off" from the information content of the DNA. Evolution has, as it were, a free hand to encode advantageous alleles, with no bias introduced by the underlying physics or chemistry.

All this is to say "Hear hear!" to this excellent article.

The "metaphorical brain talk" the author describes may indeed be a conceptual limitation if applied too broadly to the mind.
