You do, however, need to be able to tell the computer that you want to opt in (or out, I suppose) of being able to using AI to evaluate how important it thinks your work is. If you don’t have that option, it is, in fact, the computer telling you what to do. And why would you want the computer to tell you what to do?

Deep, well-considered comment.

You really changed my mind on the subject with such clear prose. From now on I will trust you over the EFF! What have they ever done for freedom or technology, anyway?

Also, since we're just saying stuff without explanation... it’s not the law, not even close; it’s the political excrement of some low-rent "intellects" styled as the law to create a more brutal bleak world.

I know who is first in the poem, my real question is: how far down the list is water9?

>I was responding to the "why is this post flagged?", and you changed scope to "justify all moderator decisions across the platform".

The actual question in the top-level comment you replied to is "why is this post, and other posts that discuss potential malfeasance from X/Grok regularly flagged?" It is implicit from follow-ups that appealing to the guidelines does not wash except as a thought-terminating cliche. In that sense I guess you are right, the topic can derail intellectual curiosity.

> I was getting the sense from multiple replies to my comments that some people were assuming I (and the moderators) wanted to censor the underlying concern about Grok as if I was a part of the American culture/political war.

The current iteration of techno-optimism characteristic of a lot of this site's userbase may have originated in SV, but it isn't the exclusive province of Californians. That's most likely what is being referred to.

>Are you joking?

No. The human body actually isn't a 737.

>This statement you made here is manipulative. You know what I mean by that comparison. Don’t try to spin it like I'm not talking about human lives.

Let me spell it out then: The mechanisms by which a human body and a 737 work are so vastly different that one may as well be alien to the other. It's quite an apples and oranges comparison.

Yeah, you can draw parallels in some areas but I'd say on the whole the analogy isn't exactly apt. That said, I'll indulge:

Imagine if every 737 was a few orders of magnitude more complex, and also so different to the point that no plane even looked or functioned the same. Then, imagine we didn't fully understand how they worked.

Point being: Medicine is fuzzy because the human body is fuzzy and imprecise. Everybody's a little different. Contrast to aviation, which is very much an exact science and engineering discipline at this point.

That of course doesn't excuse shitty healthcare systems that can clearly do better when stats indicate there's preventable adverse outcomes happening. I just don't think laying the blame at the feet of doctors somehow being too stupid to problem solve is helpful when there's a larger system that's preventing them from doing their best work for their patients. If anything that narrative is counterproductive.

>Are you yourself a doctor?

Nope, just a layperson who knows they're a layperson.

Superloop is common terminology in the firmware space. They are cruder than a giant-state-machine-like case statements(but may use still them for control flow). They usually involve many non-nested if statements for handling events, and you usually check for every event one by one on every iteration of the loop. They are an abstraction and organizational nightmare once an application gets complex enough and is ideally only used in places where an RTOS won’t fit. I would not consider asynchronous frameworks like Embassy to be superloops.
by bfrog | 2026-01-09 01:29:51+00:00
How async works with embassy is also interesting. In effect it works like a work queue, when something is waiting on a waker (interrupt) and is woken, the Future (task) is enqueued to be polled (run) by the executor.

There’s good and bad things about this. It’s clever for sure but there can be variable latency between when the hardware event occurs and when the next step in the task starts. This is a lot like zephyr/linux work queues but with linear reading code sprinkled with async/await.

The "Compute Wall" is a symptom of an efficiency bubble.

We are currently burning through H100/H200 clusters at an unprecedented scale, yet 90% of those GPU cycles are a "waste tax." We aren't calculating intelligence; we are using massive GPGPU power to "patch" 30-year-old numerical errors in discrete time-stepping (Δt).

In the race for Embodied AI, we’ve hit a wall: The Brute-Force Tax. To get high-fidelity Sim-to-Real data, we compensate for low-precision iterative solvers with massive parallelism. It’s an energetic dead-end that no amount of capital can fix—unless we change the math.

The Breakthrough: From Iteration to Hypercomplex Logic

We are introducing a New Computing Primitive based on Hypercomplex (Octonion) Manifolds. This isn't just a new algorithm; it's a structural shift in how physical state-space is represented.
Unlike traditional tensors, this manifold internalizes "Time-flow" and "Interaction-coupling" into its algebraic structure.

The "One-Look" Disruption (VC Alpha):

• Current Bottleneck: Traditional Neural Networks need to "see" 10+ frames to infer velocity/force. This leads to long Transformer sequences, high KV-cache latency, and massive VRAM consumption.

• Our Paradigm: Because our state-space is inherently causal, a Transformer needs only one "look" (a single state) to understand complete motion trends.

• The Result: We drastically shorten the context window, enabling ultra-low-latency physical intuition at the edge.

Scaling to the 100W Edge (The Economic Dividend):

• The 5000W Cost: The price of "patching" bad math with GPU clusters.

• The 100W Reality: By running our Physics Algebraic Kernel on dedicated FPGA/ASIC "Causal Processors," we bypass discrete iterations entirely. We achieve data-center-level fidelity within a handheld power envelope.

The Vision: The Physics Co-Processor We are building the "Physical Brain" for the next billion robots. This hardware-native algebraic kernel provides a high-dimensional, continuous feature space that current AI chips (Orin/Jetson) crave but cannot produce.

Deep-Dive & Technical Proof on NVIDIA Discussions: https://github.com/isaac-sim/IsaacSim/discussions/394
We are looking for architects and visionaries who understand that the next leap in AI won't come from more GPUs, but from better primitives.

> There is also a chicken and egg problem of software being dependent on hardware, and hardware only being useful if there is software to take advantage of its features.

In the 90s, as a developer you couldn't depend on that a computer had a 3D accelerator (or 3D graphics) card. So 3D video games used multiple renderers (software rendering, hardware-accelerated rendering (sometimes with different backends like Glide, OpenGL, Direct3D)).

Couldn't you simply write some "killer application" for local AI that everybody "wants", but which might be slow (even using a highly optimized CPU or GPU backend) if you don't have an NPU. Since it is a "killer application", very many people will still want to run it, even if the experience is slow.

Then as a hardware vendor, you can make the big "show-off" how much better the experience is with an NPU (AI PC) - and people will immediately want one.

Exactly the same story as for 3D accelerators and 3D graphics card where Quake/Quake 2/Quake 3: Arena was such a killer application.

Nice, I have something similar [1], a super-fast Rust/Tantivy-based full-text search across Claude Code + Codex-CLI session JSONL logs, with a TUI (for humans) and a CLI/JSONL mode for agents.

For example there’s a session-search skill and corresponding agent that can do:

aichat search —json [search params]

So you can ask Claude Code to use the searcher agent to recover arbitrary context of prior work from any of your sessions, and build on that work in a new session.
This has enabled me to completely avoid compaction.

NPUs were pushed by Microsoft, who saw the writing on the wall: AI like chatgpt will dominate the user's experience, edge computing is a huge advantage in that regard

Then where is a demo application from Microsoft of a model that I can run locally where my user experience is so much better (faster?) if my computer has an NPU?
by zamadatix | 2026-01-09 01:33:48+00:00
It's because it comes with a decent iGPU, not because of the NPU inside of that. The NPU portion is still the standard tiny 50 TOPS and could be filled with normal RAM bandwidth like on a much cheaper machine.

On the RAM bandwidth side it depends if you want to look at it as "glass is half full" or "glass is half empty". For "glass is half full" the GPU has access to a ton of RAM at ~2x-4x the bandwidth of normal system memory an iGPU would have and so you can load really big models. For "glass is half empty" that GPU memory bandwidth is still nearly 2x less than a even a 5060 dGPU (which doesn't have to share any of that bandwidth with the rest of the system), but you won't fit as large of a model on a dGPU and it won't be as power efficient.

Speaking of power efficiency - it is decently power efficient... but I wouldn't run AI on battery on mine unless I was plugged in anyways as it still eats through the battery pretty quick when doing so. Great general workstation laptop for the size and wattage though.

I've been making use of gpt-oss-120b extensively for a range of projects, commercial and price, because providers on OpenRouter make it essentially free and instant, and it's roughly as capable at o4-mini was in my experience.

That said, I'm a little surprised to hear you're having great success with it as a coding agent. It's "obviously" worse than the frontier models, and even they can making blindly dumb decisions pretty regularly. Maybe I should give it a shot.

On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.

Off-Topic: Most stories about politics, or crime, or sports, or celebrities, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.

I can think of many way more on-topic submissions. They are the ones where no one is upset and everyone is nerding out about an obscure topic.

Let me be clear, classifying this submission as off topic is not cut and dry. My point was there is clearly good justification for it in the official guidelines.

- it's not a topic that fosters intellectual curiosity because it is somewhat rage inducing. It's outrageous. It's frustrating and it's scary. It's very likely to upset people.

- it's also related to a controversial celebrity

- it's also about crime

- it's also something that surely will be covered by TV news

These things are laid out right there clearly in the guidelines.

I am choosing to give the moderators the benefit of the doubt because I believe they are doing their best to try and foster good intellectually curious dialog and minimize emotionally charged heel digging disrespectful debates and flame wars.

> Sandboxing these things is a good idea anyways.

Honestly, one thing I don't understand is why agents aren't organized with unique user or group permissions. Like if we're going to be lazy and not make a container for them then why the fuck are we not doing basic security things like permission handling.

Like we want to act like these programs are identical to a person on a system but at the same time we're not treating them like we would another person on the system? Give me a fucking claude user and/or group. If I want to remove `git` or `rm` from that user, great! Also makes giving directory access a lot easier. Don't have to just trust that the program isn't going to go fuck with some other directory

Google will know a lot more about most people. Because everything is in their cloud. Than the provider of your local OS. Doesn't seem to hurt Gemini though.

And really, Copilot the chatbot on web and windows (specifying because there's too many Copilot products to count) kinda sucks anyway. Especially the free version. It's notably worse than chatgpt even though it's just chatgpt. Whatever they're doing it, they're screwing it up.

I don't understand why Microsoft is trying so hard to promote a service that isn't even theirs, but then again edge isn't actually their own browser either. It seems to be that getting the brand name out there is the main thing they care about.

Someone was murdered with plenty of video footage, it's reasonable to form some preliminary conclusions.

As you're invoking a general concept, I presume you have much harsher criticism for the administration, which is pushing bald faced lies [0] and rejecting responsibility for the situation rather than taking even a moment to assess?

The flip side of this refrain of "don't trust your lying eyes" is outright lying by this administration "supported" by narrow video clips that don't tell the whole story. Like a clip of "stop" and the victim trying to drive away is pretty convincing, if you're not shown the other clip where another gang member was yelling "move move move".

[0] The basic known facts here are that ICE electively confronted and escalated a situation with an American citizen, did not follow their own rules of engagement, the woman was shot repeatedly, and then a nearby doctor tried to render emergency aid and was prevented from doing so, correct?

I guess they didn’t learn from the Tegra X1 which was famously responsible for the boot rom exploit on the original model of the Nintendo Switch.

> Htmx is more like a simplified way to do SPA-like things.

Okay. Then we agree. "Htmx is power tools for using Javascript to alter HTML".

With the implicit premise of starting from javascript you see that as "Power Tools for HTML". Without this premise I see it as "Power Tools for Javascript".

I think this distinction is not only important because I question the premise, but because many people who've talked to me about Htmx are confused about what Htmx is and believe that it works without javascript. This is not Htmx's fault, of course, but it could be made clearer by avoiding easily misinterpreted headlines like this.

Whoa. Finally someone I relate with! Thanks for such amazing intel!

In my opinion forays into biology by moonshot hopefuls fail for one of two reasons: either they completely ignore all the current wisdom from academia and industry, or they recruit the very academia people who are culturally responsible for the science rot we have at this time. Calico (and CZI, and im starting to fear, Arc) fell prey to the latter. Once you recruit one tenured professor IMO youre done. The level of tenure track trauma and academic rot they bring in can burn even a trillion dollars into dead-end initiatives.

IMO (after decades of daydreaming about this scenario), the only plausible way to recreate a Bell labs for Biology is to start something behind a single radical person, and recruit the smartest undergrads into that place directly. Ensure that they never become experts at just one thing so they have no allegiance to a method or field. And then let that hoarde loose on a single problem and see what comes out. For better or worse neuralink seems to be doing that right. Just wish they didnt abuse the monkeys that much!

To me success in biotechnology is if I measurably help make a drug that makes a person smile and breathe easy that would otherwise not have. Surprisingly easy and hard at the same time.

All these things are so amusing. Amjad Masad dislikes Israel and is fine with Saudi Arabia. Palmer Luckey will spend his life doing rainman calculations on the angle of the car in Minneapolis. One is a “terrorist”, other is a “fascist”.

But you can tell it’s all motivated reasoning. Standing with your tribe. It’s not much of a matter of honour. It’s just flashing your banners.

In the end, they are wealthy, but they are just people. And they have all these things and why do I really care what Ja Rule has to say about the new cyclone.

I actually prefer no syntax highlighting, and I certainly wouldn't make any claims about it being useful. But something being "useful" is often personal - I find IDEs useful, others find Vim useful, maybe one is better or worse than the other or maybe we're all different and our brains function in different ways and that explains the difference.

With assembly versus say, Go for writing a web server? That's trivially observable, good luck arguing against that one.

jacquesm is a longstanding member of this community with serious technical chops. He has fabricated his own fucking windmill, among many other awe-inducing projects.

I am an American, and I generally find his political judgements to be spot on, or at the very least enlightening. Frankly given the abjectly moronic siren song narratives too many of my "fellow countrymen" have fallen for, we could use more outside context to steer us through these dark times.

Meanwhile, you seem to be some kind of fascist-cheerleader who relishes in trolling. All over this thread, you've spared no opportunity to rally support for agents of the state executing an American citizen and mother. I would tell you to get the fuck out of my country, whose values you clearly have no understanding or appreciation of, before Lady Liberty sticks her torch up your ass. But really you're just sick with social media psychosis, and you need help.

The point of certificates is that they prevent things like MITM attacks on updates that replace the legitimate app with a malicious version. They also prevent you from installing fake software if you know how to use them, e.g from a malicious ad that looked just like the real Logitech site. They're also requited for all mac app store apps, it's not really about the specific use case of the app.

> They also aren't considering the spirit of the guidelines to foster intellectually curious dialog and avoid topics that derail it.

Yes they are. We considered it and came to a different conclusion than you. We believe that this topic does foster intellectually curious dialog and your insistence that we don't is frustrating.

> Not if the topic consistently devolves away from intellectually curious dialog. There are clearly a lot of charged emotions and strong opinions across most of these comments.

IMO, this is the core problem. Charged emotions and strong opinions are not the opposite of intellectually curious dialog. An insistence that conversation play out like an abstract game separated from all feeling is anathema to useful communication, in my opinion. People are not better, smarter, or more interesting by being dispassionate. Especially when the topic is wide scale mass abuse and harassment. Feelings are not bad.

I haven't tried using agents to make a full editor, but Claude Code and Gemini CLI are actually quite good at writing Obsidian plugins, or modifying existing ones. You can start with an existing one that's 90% of what you want (which tends to be the case with note-taking/PKM systems: people are so idiosyncratic that solutions built by others almost work, but not quite) and tweak it to be exactly right for you.

My own Obsidian setup has improved quite a bit in the last couple months because I can just ask Claude to change one or two things about plugins I got from the store.

This easier to solve if you use a permutation instead of hash functions.

Let h0 be the larger table, and h1 the smaller. N = len(h0), M = len(h1). Pretend the elements of the tables are sequentially indexed. Element[0] is h0[0], Element[N] is h1[0], etc.

h0' = Resize(h0, (N+M)*capacity_factor)

for x in 0...(range):
y = permute(x, 0, (N+M)*capacity_factor)
if(y >= N) move_to(h0'[y], element[x])

One allocation and you move the minimum number of elements needed to eliminate primary clustering. Elements in h0 that aren't moved would presumably remain correctly indexed. You have to move the remaining elements of h1 as well, but that cluttered things.

Any randomish permutation works, from basic ones up to cryptographic. If your permutation only works on certain powers of two, iterate it until the result is in range.

> will you overwrite pwbuf when writing past password?

Right.

> If so, could you type the same password that’s exactly 100 bytes twice and then hit enter to gain root? With only clobbering one additional byte, of ttybuf?

Almost. You need to type crypt(password) in the part that overflows to pwbuf.
