That level of argument is already at Reddit level where every little detail is a reason to be "right". This is tiresome.

Look: if someone is jamming something with a 100 watt transmitter which causes impact on the adversary, that location is quickly bombed because it is now a giant beacon that advertises its position.

I'll even throw a cheap appeal to authority and mention that I've done this stuff professionally in the military for a decade. I'll still trust more on the usability of my cheap walkie-talkie capable of +50km range and satellite texts than an exotic LoRa used on the ground by few internet warriors.

>I don't agree with this. Not hitting pedestrians should not just be an afterthought.

You're disagreeing with something I didn't say. There's a difference between afterthought and the primary initiator of the stop in a situation like this.

>Of course the car should recognize the stop sign, but there are cases in which stop signs are obstructed or missing, and in those cases pedestrians should still not be hit by a car.

The surprise pedestrian test is one that any vehicle can be made to fail by sheer physics. Avoiding errant pedestrians like in the video will likely only come as a byproduct of better situational behavior by self driving vehicles. The overwhelming majority of drivers know to ignore the speed limit if the situation is rife with pedestrians or otherwise sus and are generally fine with missing/obstructed stop signs. I don't know what route self driving software will take to approximate such behavior but it likely will need to.

> i'm sure you'll be able to figure it all out fast

Even if you do, a radio by itself is useless unless you can trust the people on the other end.

Perhaps your generator won’t start. A voice on the radio sounds like a mechanic and claims you need a new spark plug. He can offer you one if you can meet him in a neighborhood 3 minutes from your house. Is this a benevolent actor with small engine expertise and a garage full of spare parts? A well meaning elderly man with dementia? An opportunist luring you into a robbery?

You lose a tremendous tactical advantage in this situation if you’ve never met any local radio operators, gotten a sense of where they live and what they do for a living. Some are skilled experts. Some are blowhards who confidently give bad advice. Some live near you. Some are 100 miles away. You can figure it out, but it takes time that you don’t have in the middle of a disaster.

Get your license. Join your local Amateur Radio Club. Use your radio to chat with someone at least once a week. If you have signal quality issues, experiment with upgrading your equipment. Then the radio in your bug out bag will be of some value to you.

For many years at FB, suffixing dangerous or really-deprecated tokens with `_DO_NOT_USE_OR_YOU_WILL_BE_FIRED` was the standard. Everyone[^1] was in on the joke.

In the middle of the pandemic when ~50% of the workforce had started post-2020, it and other things became complaints for causing fear/uncertainty. We didn't do the best job on-boarding remote people and making them feel part of the culture at that time.

[^1]: It was a big company so this statement could only be true in the circles I had access to.

I would use Reticulum instead of Meshtastic. https://reticulum.network

Pros: - it can actually scale past 20 devices - Forward secrecy encryption - Is designed to support multiple underlying transport systems such as TCP or LoRa - Announce based routing rather than flooding the entire network which is order of magnitudes faster Cons: - Not as many nodes as Meshtastic has - Python implementation with no C implementation (can be speed up with cython however)
by flufluflufluffy | 2025-06-16 12:44:58+00:00
Yes, exactly. The model is based on (in the first approach) a “lattice” of some type of undiscovered particle-like thing (what they refer to as “qubits” in the article, which is unfortunate because it is NOT the same “qubit” from quantum computing) permeating space time. Or maybe more aptly, it is that lattice from which spacetime emerges. And what we observe as the force of gravity emerges from the entropic forces happening in this lattice.
by cwharris | 2025-06-16 12:45:04+00:00
This seems backwards. Entropy is a dispersive force — it favors distribution and disorder. But the universe clumps. Planets, stars, galaxies — all of them are low-entropy configurations.

So how did scattered dust particles form the planet we’re standing on… through entropy?

If gravity is just emergent from entropy, then it should be fighting against planet formation, not causing it. There’s a missing piece here — maybe coherence, resonance, or field attraction. But “just entropy”? That doesn’t explain formation. It explains dissolution.

The "stablecoin" part makes little sense. Walmart and Amazon could, with less effort, give customers store currency balances in a database. That would also let them bypass the existing payment processing industry.

It's almost as if "stablecoin" is a term included to make it sound fancier, cooler, more modern, or maybe just to push it a little further away from being called "company scrip".

I agree with this assessment. I've been running two nodes for about a year, maybe longer, and in that time, I've only had perhaps two contacts.

Even with a YAGI or a dedicated pole antenna, both tuned to 868 MHz, the range in my location is quite poor. The signal seems to drop off quickly, even after walking just a kilometer down the road. While I understand that height is key (and my antennas are fairly high), it appears that 868 MHz attenuates very rapidly.

So, to reiterate, I don't believe Meshtastic is a particularly effective solution. The principle behind it is sound, but the practical execution falls short. I think established methods like Hamnet and traditional amateur radio are far superior, especially now with SDRs making a simple handheld radio incredibly affordable (around €20)

My point was we can can't prove that LLM's have consciousness. Yes, the reverse is also true. It is possible that we wouldn't really be able to tell if a AI gained consciousness as that might look very differently than we expect.

An important standard for any scientific theory or hypothesis is to be falsifiable . Good old Russell's teapot. We can't disprove that that a small teapot too small to be seen by telescopes, orbits the Sun somewhere in space between the Earth and Mars. So should we assume it is true? No the burden of proof lies on those that make the claim.

So yes, I could not 100 percent disprove that certain LLM's don't show signs of consciousness but that is reversing the burden of proof. Those that make the claims that LLM's are capable of suffering, that they show signs of consciousness need to deliver. If they can't, it is reasonable to assume they are full of shit.

People here accuse me to be scholastic and too philosophical but the the reverse is true. Yes, we barely know how human brains work and how consciousness evolved but whoever doesn't see the qualitative difference between a human being and an LLM really needs to touch grass.

Does LIDAR work underwater?

FWIU in Grand Traverse Bay, Lake Michigan, there's a 9,000 year old stonehenge-like structure 40 feet underwater; that's 4000 thousand years older than Stonehenge and about 6000 years older than the Osireoin and the Pyramids.

/? Michigan underwater stonehenge: https://www.google.com/search?q=michigan+underwater+stonehen...

There's not even a name or a wikipedia page for the site? There are various presumed Clovis sites which are now underwater in TN, as well.

What do you think a human using the recursive solution looks like?

If you ask someone how the puzzle works, they're overwhelmingly likely to tell you:

"To move disc 7, first you move discs 1-6 to the third peg, then you move disc 7[, and then you can put discs 1-6 back on top of it]."

This is an explicitly recursive statement of the solution. But the implementation is just that you count down from 7 to 1 while toggling which peg is "the third peg". You can optimize that further by dividing 7 by 2 and taking the remainder, but even if you don't do that, you're using constant space.

What would a human be doing (or thinking) differently, if they were using the recursive algorithm?

To perhaps add a dimension to the issue, imagine that one day you woke up and the roads were not functional. Many people would have a great time, as long as they knew the roads were going to be functional later that day. If it turned into a longer problem, the disruption would have vast and unpleasant consequences.

We do not yet have an awareness of our dependence on technologies, nor of how fragile those technologies can be. If someone had suggested years ago that perhaps we should prepare for a disruption in say, the egg supply, that would have provoked laughter. And jokes like, well I really don't like eggs. Or what about toilet paper hoarding? Given just those two events alone, one might decide that disruptions are at least somewhat of a possibility. That our past assumptions of an unending supply of goods and services might not hold in the future.

It is a funny comment, and there are several dependencies I personally would not miss. Until I did.

Personally, the interesting concept is resiliency in general.

Interesting study but I don't really get the point of the search group. Looking at the essay prompts, they all seem like fluffy, opinion based stuff. How would you even use a search engine to help you in that case? Quote some guy who had an opinion? Personally I think my approach would be identical whether put in the web-search or the only-brain group.

For devs, this just solidifies that we should be writing pure standard JS/TS, HTML, CSS, SVG, and nothing else.

Things that diverge from browser standards (like frameworks instead of web components, or special APIs) just create a place for things to break.

That said, if you want a special browser you can guarantee will be available, just wrap it in Electron and ship that, like many big players do.

Seekable formats also allow random reads which lets you do trickery like booting qemu VMs from remotely hosted, compressed files (over HTTPS). We do this already for xz: https://libguestfs.org/nbdkit-xz-filter.1.html https://rwmj.wordpress.com/2018/11/23/nbdkit-xz-curl/

Has zstd actually standardized the seekable version? Last I checked (which was quite a while ago) it had not been declared a standard, so I was reluctant to write a filter for nbdkit, even though it's very much a requested feature.

Although I never went into one of these buildings, in the early 80's I was a sub-contractor burying cable for SWB. I was always amazed at all the property they controlled. I had access to all their construction yards, which were spread out all over the city, some of them in the suburbs. Protecting these yards from theft was always a nightmare for them.

Yes, this is a seriously difficult problem with only partial solutions.

The basic math of any kind of negotiation is that you need the minimum set of cryptographic parameters supported by both sides to be secure enough to resist downgrade. This is too small a space to support a complete accounting of the situation, but roughly:

- In pre-TLS 1.3 versions of TLS, the Finished message was intended to provide secure negotiation as long as the weakest joint key exchange was secure, even if the weakest joint record protection algorithm was insecure, because the Finished provides integrity for the handshake outside of the record layer.

- In TLS 1.3, the negotiation messages are also signed by the server, which is intended to protect negotiation as long as the weakest joint signature algorithm is secure. This is (I believe) the best you can do with a client and server which have never talked to each other, because if the signature algorithm is insecure, the attacker can just impersonate the server directly.

- TLS 1.3 also includes a mechanism intended to prevent against TLS 1.3 -> TLS 1.2 downgrade as long as the TLS 1.2 cipher suite involves server signing (as a practical matter, this means ECDHE). Briefly, the idea is to use a sentinel value in the random nonces, which are signed even in TLS 1.2 (https://www.rfc-editor.org/rfc/rfc8446#section-4.1.3).

"Big ears, small mouth" is exactly what the regulations are designed to encourage, so I don't foresee regulatory issues.

You don't even need extra hardware for the duplexing; the common SX1276 chip has separate Tx and Rx pins which are typically combined on the PCB. All you need is to route a PCB that brings 'em out separately, if that's what you want to do.

In practice it's tricky to aim two dishes the exact same place, so using a single dish with a single antenna at its focus is probably quite a bit more practical. The SX1276 also has a PA control pin, invert that and you've got your LNA control signal. Or don't bother with the LNA, and simply mount the transceiver at the focus to minimize RF feedline losses. You'd give up a smidgen of performance but gain a lot of simplicity. (There would still be coax running down the boom, but it would be carrying the wifi/bluetooth signal outside the dish's aperture!)

And herein lies the fundamental power of the LLM and why it can even solve "impressive" problems: it is able to navigate a space that humans can't trivially - massive amounts of information and ability to parse through walls of simple logic/text.

LLMs are at their best when the context capacity of the human is stretched and the task doesn't really take any reasoning but requires an extraction of some basic, common pattern.

Post-disaster onboarding is complicated by app store lockdowns and the difficulty of sideloading. Heck, even establishing plain http or self-signed https connections is tricky on phones now.

I'm sure someone smarter than me has a toolkit for these things, I just don't know where to find it.

Store-and-forward-wise, NNCP is designed for this, but it's not widespread yet.

I do agree there is a sense in which this has always been true. But most people’s constructed worlds overlapped quite significantly up until now; it was necessary for survival.

I think that condition is weakening. Just look at how wealth affects people; If 99% of your interlocutors are sycophants, you lose grip on reality. There is a very clear and dangerous attractor state where everyone gets this, thinking that they want it.

Models are not word for word copies of large sections of text. They are capable of emitting that text though.

It would be interesting to look at what legal precidents were set regarding mp3s or other encodings. Is the encoding itself an infringement, or is it the decoding, or is it the distribution of a decodable form of a work.

There is also the distinction with a lossy encoding that encodes a single work. There is clarity when the encoded form serves no other purpose other than to be decoded into a given work. When the encoding acts as a bulk archive, does the responsibility shift to those who choose what to extract from the archive?

> That's the whole selling point of AI tools. "You can do this without learning it, because the AI knows how"

I'm sure we are veering into "No true Scotsman" territory but that's not the type of learning/tools I'm suggesting. "Vibe Coding" is a scourge for anything more than a one-off POC but LLMs themselves are very helpful in pinpointing errors, writing common blocks of code (Copilot auto-complete style), and even things like Aider/Claude Code can be used in a good way if and only if you are reviewing _all_ the code it generates.

As soon as you disconnect yourself from the code it's game over. If you find yourself saying "Well it does what I want, commit/ship it" then you're doing it wrong.

On the other hand, there are some people who refuse to use LLMs for a wide range of reasons ranging from silly to absurd. Those people will be passed by and have no one to blame but themselves. LLMs are simply another tool in the tool box.

I am not a horse cart driver, I am a transportation expert. If the means of transport changes/advances then so will I. I will not get bogged down in "I've been driving horses for XX years and that's what I want do till the day I die", that's just silly. You have to change with the times.

I’ve noticed that many of the hard boards have a “choke point” in the solution where there are a small number of places you can place a specific queen but the information needed to place it can be difficult to gather.

A hacky trick is to place a queen and then ask for a hint. If deployed well, you can use this short circuit the challenge and often solve the puzzle in a fraction of the time.

There isn’t any penalty for taking a hint beyond you’re locked out of your next hint for a period of time.

Correct me if I'm wrong, but it doesn't seem like you provide the equivalent of Seekable::decompress in zstd_seekable which decompresses at a specific offset, without having to calculate which frame(s) to decompress.

This is basically the only function I use from zstd_seekable, so it would be nice to have that in zeekstd as well.

I'm managing a long-term team member who has become very difficult to manage. They appear polite, cooperative, never openly push back. They acknowledge requests, attend meetings, and respond professionally.

But in reality:

- Tasks come back half-done, again and again

- Feedback is acknowledge and then ignored

- Bugs get buried in vague responses like “works on my side”

- Messages are not replied to sometimes, or they claim “was busy, didn’t see it”

- They never say “no,” but everything gets stuck in this slow grind

They’re not openly insubordinate. Just draining.

We can’t fire them easily as they're here for over 10 years they haven’t broken any rules or gross misconduct.

But they’ve made themselves completely unreliable in the last few months.

Anyone dealt with this kind of passive resistance?

How do you actually move someone like this — or do you just sideline them and minimize the damage?

Caveat/preface to prevent trolls: FSD is a sham and money grab at best, death trap at worst, etc.

But, I've read through your chain of rplies to OP and maybe I can help with my POV.

OP is replying in good faith showing "this sampling incident is out of scope of production testing/cars for several reasons, all greatly skewing the testing from this known bad actor source."

And you reply with "Zero systemic reproducible mistakes is the only acceptable critera."

Well then, you should know, that is the current situation. In tesla testing, they achieve this. The "test" in this article, which the OP is pointing out, is not a standardized test via Tesla on current platforms. SO be careful with your ultimatums, or you might give the corporation a green light to say "look! we tested it!".

I am not a tesla fan. However, I also am aware that yesterday, thousands of people across the world where mowed down by human operators.

If I put out a test video showing that a human runs over another human with minimum circumstances met, IE; rain, distraction, tires, density, etc., would you call for a halt on all human driving? Of course not, you'd investigate the root cause, which is most of the time, distracted or impaired driving.

"cosmic sidekick for navigating life with the power of the stars...with a fresh, no-BS approach."

There's a great deal of humor here. Astrology is conceptually interesting, in the same way that me summoning a Greek, Norse, or Hindu deity in old school final fantasy is interesting. I get the feeling this place isn't filled with your target audience though.

Anyway, consider allowing users to type in their birth day in addition to (or maybe even entirely replacing) the day widgets. It's not immediately obvious where to click to navigate to a year only selection for instance.

And even though it may seem obvious, a prompt that says "enter your birthdate" or something similar oriented around the entry fields would be a good idea for the uninitiated but curious.

> Miyazaki's art is Miyazaki's. If another artist were to come along and imitate his style, especially after he is gone, that is still not Miyazaki. That is whomever's that is's style and it's disrespectful of both to call it Miyazaki.

Yes, but also no. Miyazaki’s art style is distinctive and certainly stands out, but it’s also very clearly a “mass produced” thing. In that I mean a team of animators are all creating frames of art in the Miyazaki style that are obviously not drawn by Miyazaki, but we call them Miyazaki art because they’re conglomerated into a single work under his direction. The question is how many frames of a movie have to be personally drawn by Miyazaki in order for something to be a Miyazaki film? If he directs the art and movie, but doesn’t actually draw anything himself, is that still a Miyazaki film? Is that “disrespectful” to him? More specifically, is the art style what makes a film a Miyazaki film or is it the world, the ideas and the individual human moments that are chosen to be drawn that make the film?
