Long ago, Canonical did some shady stuff with the now-deprecated apt-key "net-update" signing validation for updating of GnuPG keys over the network, an exclusive Ubuntu "feature" Debian didn't even adopt that in theory allowed the same thing.

First I thought CVE-2012-3587 was incompetence... but then seeing CVE-2012-0954 after it, I couldn't help think something more was at bay as something connected to a nation state. It does not surprise me in the least to see nation state attackers exploiting N++. Because I've also on very sensitive enterprise PAM systems in F500/research/academia, and about 10% of the time it felt like I'd see Notepad++ on internet-connected systems used for security tooling because vanilla notepad is indeed garbage. It does not surprise me at all this has been used as an attack vector.

...this is actually a really interesting thought.

The act of writing in lowercase is not, in itself, funnier. But writing in the training set that is in all lowercase is _probably_ going to be the funnier writing.

Considering modern pundits online, "lowercase" is usually the case of the humourist. Lowercase also tends to be the case of sarcasm, almost exclusively deployed to be funny.

So it would make sense that models attempting to select for funny would also write in lowercase.

> I think producing detailed enough specification requires same or even larger amount of work than writing code

Our team has started dedicating much more time writing documentation for our SaaS app, no one seems to want to do it naturally, but there is very large potential for opening your system to machine automation. Not just for coding but customer facing tooling. I saw a preview of that possible future using NewRelic where they have an AI chat use their existing SQL-like query language to build tables and charts from natural language queries right in the web app. Theirs kinda sucks but there's so much potential there that it is very likely going to change how we build UIs and software interfaces.

Plus it also helps sales, support, and SEO having lots of documentation on how stuff works.

I have 20+ years in municipal IT. Almost 10 years ago, I was standing in line in the morning at our local Jack in the Box, with a man in front of me, who obviously painted for a living (white overalls, paint all over). While waiting he glanced at my shirt with the municipal logo and Information Technology insignia. “You work in IT?” “Yep.” I replied. Then he identified himself as a former project manager, burnt out, rattled off a list of companies he did contract work for, and said he’s now happier than he’s ever been. Take that for what it’s worth. After all these years, I’ve realized the value of an occupation that makes perfect sense. Information Technology is not one of them.

That's what I was trying to get at -- yes, you can say that sysvinit is easier to understand than systemd, and less of a black box. But, even still, a "real Linux distribution" is full of these black boxes, especially the closer you get to being able to run "real applications". I'd argue that once you get into full desktop seat management, you add so much complexity on top of sysvinit that the difference narrows...

Which is why I asked "learn about what stuff". I think if the goal is to learn about "Unix" or OS design/ideas, you're better off with a leaner, "pedagogical" OS, like xv6. If the goal is to piece together an OS and really understand each piece, I don't think you really want sysvinit. You want something closer to an /etc/rc.local that just kicks off a few daemons and hopes for the best.

You can argue that sysvinit makes a better "compromise" between usability and clarity, and I'd entertain that idea, but then I think dinit is far easier to understand than sysvinit. And of course, at that point you can shave yaks till you fill the bike shed with wool.

Realistically, as much as people may hate it, if you have to pick a single init to standardize on for clarity and "building an entire Linux distro from the ground up, understanding how every piece fits together", systemd is the most rational choice. It's the most representative of the ecosystem, and requires the least "extra layers" to make the "desktop layer" work.

We use browser-use for password change automation (thepassword.app) and the detection landscape is evolving fast.

The key insight from this article: sites are shifting from "detect bots" to "detect automation intent." For user-initiated tasks like password changes, this is actually helpful - the automation is authorized, just executed by AI instead of human fingers.

The interesting challenge is that different sites have wildly different detection approaches. Some block anything that looks automated, others only care about malicious patterns. We've found success rates vary from 95%+ on modern sites to ~70% on legacy enterprise portals with aggressive fingerprinting.

Would love to see benchmarks on detection bypass rates across different site categories.

Most everyone here is just angry Elon opened the door for freedom of speech to exist online and started the process of uncovering the left's extreme corruption. They feel betrayed by him so he's enemy #1. Literally could cure cancer and he'd still be branded as evil by the left. Ironic as he's arguably done more for leftist causes (renewables, ev's, etc) than anyone else on the planet.

These are private companies, with private investors. If Elon really screwed all investors over and over again he wouldnt be able to raise money repeatedly. But he has no problem raising money. Because the claims that he's doing shady things or screwing investors is entirely unfounded. Same goes with the claims that he's an idiot or not that smart. If thats really the case, show me what you've accomplished with your genius.

It takes intelligence to recognize intelligence. An idiot cant recognize a genuis.

The solution is proxy everything. The agent doesn't have an api key, or yoyr actual credit card. It has proxies of everything but the actual agent lives in a locked box.

Control all input out of it with proper security controls on it.

While not perfect it aleast gives you a fighting chance when your AI decides to send a random your SSN and a credit card to block it.

If the $45 is meant to be temporary, it can reasonably be looked as a fine to encourage people to get their RealID.

I don’t think the existence of the fine itself is necessarily evidence of a cash grab.

If it isn’t temporary and extends beyond a year or two, then it probably is just meant to be a cash grab.

Just picture a square based pyramid, like a pyramid from egypt, thats the rough shape. Lets pretend the bottom is square. For thermodynamic analysis, we can just pretend the scale is irrelevant, it could be 4 cm x 4 cm base or 4 km x 4 km base. Now stretch the pyramid so the height of the tip is 3 times the length of the sides of the square base, so 12 cm or 12 km in the random examples above.

If the base were a solar panel aimed perpendicular to sun, then the tip is facing away and all side triangles faces of the pyramid are in the shade.

I voluntarily give up heat dissipation area on 2 of the 4 triangular sides (just to make calculations easier, if we make them thermally reflective -emissivity 0-, we can't shed heat, but also don't absorb heat coming from lukewarm Earth).

The remaining 2 triangular sides will be large enough that the temperature of the triangular panels is kept below 300 K.

The panels also serve as the cold heat baths, i.e. the thermal sinks for the compute on board.

Not sure what you mean with wings, I intentionally chose a convex shape like a pyramid so that no part of the surface of the pyramid can see another part of the surface, so no self-obstruction for shedding heat etc...

If this doesn't answer your question, feel free to ask a new question so I understand what your actual question is.

The electrical power available for compute will be approximately 20% (efficiency of solar panels) times the area of the square base L ^ 2 times 1360 W / m ^ 2 .

The electrical power thus scales quadratically with the chosen side length, and thus linearly with the area of the square base.
Show HN: Stream-based AI with neurological multi-gate (Na⁺/θ/NMDA)
by CSCT-NAIL | 2026-02-03 02:59:00+00:00
Current LLMs struggle with compositional inference because they lack physical boundaries. CSCT implements a neurological multi-gate mechanism (Na⁺/θ/NMDA) to enforce $L^1$ geometry and physical grounding. In my experiments (EX8/9), this architecture achieved 96.7% success in compositional inference within the convex hull—far outperforming unconstrained models.Key features:Stream-based: No batching or static context; it processes information as a continuous flow.Neurological Gating: Computational implementation of θ-γ coupling using Na⁺ and NMDA-inspired gates.Zero-shot Reasoning: Incurs no "hallucination" for in-hull compositions.Detailed technical write-up: [https://dev.to/csctnail/-a-new-ai-architecture-without-prior...]I’m eager to hear your thoughts on this "Projected Dynamical System" approach to cognition.

Yes, I've been using a K3 for a few weeks now. It's quite pleasant, and if I use all 16 cores (8x X100 and 8x A100) then it builds a Linux kernel almost 3x faster than my one year old Milk-V Megrez and almost 5x faster than K1.

14m25.56s SpacemiT K3, 8 X100 cores + 8 A100 cores
16m55.637s SpacemiT K3, 8 X100 cores @2.4 GHz
19m12.787s i9-13900HX, 24C/32T @5.4 GHz, riscv64/ubuntu docker
39m23.187s SpacemiT K3, 8 A100 cores @2.0 GHz
42m12.414s Milk-V Megrez, 4 P550 cores @1.8 GHz
67m35.189s VisionFive 2, 4 U74 cores @1.5 GHz
70m57.001s LicheePi 3A, 8 X60 cores @1.6 GHz

It's also great that it's now faster than a recent high end x86 with a lot of cores running QEMU.

Note that the all-cores K3 result is running a distccd on each cluster, which adds quite a bit of overhead compared to a simple `make` on local cores. All the same it shaves 2.5 minutes off. In theory, doing Amdahl calculation on the X100 and A100 times, it might be possible to get close to 11m50s with a more efficient means of using heterogenous cores, but distcc was easy to do.

RISC-V SBC single-core performance has been better than x86+QEMU since the VisionFive 2 (or HiFive Unmatched) but we didn't have enough cores unless you spent $2500 for a Pioneer.

Busy Beaver gets a lot of love, but the fast growing hierarchy is both constructive and can go way, way, waaaaay beyond current known BB bounds. This makes their size much more viscerally apparent than gesturing vaguely at BB(BB(BB(100))) or whatever, IMHO.

David Metzler has this really cool playlist "Ridiculously Huge Numbers" that digs into the details in an accessible way:

https://www.youtube.com/playlist?list=PL3A50BB9C34AB36B3

By the end, you're thinking about functions that grow so fast TREE is utterly insignificant. Surprisingly, getting there just needs a small bit of machinery beyond Peano Arithmetic [0].

Then you can ponder doing all that but making a tiny tweak by replacing succesorship with BB. Holy cow...

Have you tested Supercruise?

There is another way to view this. FSD plays fast and loose because they are constantly iterating. The culture at Musk co is that if you dont' keep pushing updates you are in trouble so do we really want to trust that each of his numerous updates are truly tested? This guy is a pathological liar after all. How many lawsuits are they dealing with now?

Supercruise only runs on pre mapped routes. If my life is on the line, I'd rather take the pre mapped routes and supercruise design is better at preventing people playing games to defeat the system (ex.shoving an orange in the steering wheel) so I know that others using the system on the road are following the system guidelines.

Supercruise may not do everything FSD does but it cuts out a large portion of the "fatigue" portion of driving and as a result can be highly trusted value add.

It was so ridiculously shortsighted of them to decide as a strategy to underpay all their employees compared to the industry standard, especially considering their ambitions are still fairly unbounded (meaning it's not like they said everything we do will be easier than Google or Meta so we don't need to compete for the same pool of talent).

But maybe such a decision was inevitable in their culture. And now it's very difficult to correct.

Bezos has been pushing manufacturing-in-space for a long time, as a ideal candidate for what to do in space that you might prefer to not do on Earth. Robotics, AI automation, manufacturing - combo it in space, let the robots manufacture for us in space. Abundant energy, low concerns about most forms of pollution. We'll need to dramatically improve our ability to transit mass to and from cheaply first of course (we're obviously talking many decades into the future).

I will be glad to be wrong about, but…

I was under the impression that parallel and concurrent code was the dominant paradigm for programming tasks currently going in most of the semi-mainstream domains. I am certainly willing to concede that I could just be in a bubble that thinks about and designs for concurrency and parallelism as a first class concern, but it doesn’t seem that way.

I mean one of the large features/touted benefits for Rust is the single mutable XOR multiple immutable semantics explicitly to assist with problems in parallel/concurrent code, all of the OTP languages are built on top of a ridiculously parallel and distributed first ‘VM’. It strikes me as peculiar that these types of languages and ecosystems would be so, apparently, popular if the primary use case of ‘safe’/resilient parallel/concurrent code was not a large concern.
by comex | 2026-02-03 03:05:53+00:00
Personally I’ve handled this by just ignoring the gradual part and keeping everything strictly typed. This sometimes requires some awkwardness, such as declaring a variable for an expression I would otherwise just write inline as part of another expression, because Pyright couldn’t infer the type and you need to declare a variable in order to explicitly specify a type. Still, I’ve been quite satisfied with the results. However, this is mostly in the context of new, small, mostly single-author Python codebases; I imagine it would be more annoying in other contexts.

This. Since Firefox claims to be a privacy-first browser, it should, by default, use the Arkenfox settings (report spoofed values for language, screen size, fonts, and many other attributes that aid fingerprinting), and include uBlock Origin out of the box.

But it should go even further; the ultimate goal should be for all Firefox users to basically look the same from the point of view of third parties and put an end to tracking in the modern Web.

If accurate, this strikes me as something like malicious compliance.

> Translations, which help you browse the web in your preferred language.

Machine translation can be useful when you want to get the gist of something in a language you don't know.

> Alt text in PDFs, which add accessibility descriptions to images in PDF pages.

OCR? Okay...

> AI-enhanced tab grouping, which suggests related tabs and group names.

What is this feature even trying to do? It sounds like ill-defined trash.

> Link previews, which show key points before you open a link.

Or I could just click the link.

> AI chatbot in the sidebar, which lets you use your chosen chatbot as you browse, including options like Anthropic Claude, ChatGPT, Microsoft Copilot, Google Gemini and Le Chat Mistral.

This is the thing that most people are probably complaining about. Lumping the other features in with it is a distraction.

> There's no unified lexicon on cli tooling

While there isn't there is more than most people give credit to. It shouldn't be too much of a surprise giving cli people write cli tools getting inspiration from cli tools. I mean we can't even say there's a unifying language in the GUI space.

> The real big brain approach here is to divorce the idea of vim from the command line editor and use it as a plugin in an IDE

Maybe I'll be convinced when a vim plugin or "vim bindings" represents something close to actual vim. I need a lot more than hjkl, gg, gG and such for movements. It's crazy how few even have H,M,L let alone <C-F>, <C-B>. I'm really surprised so many don't have / bit less surprised at * and the like. An ide giving me vim bindings needs to also give me :Ex, tabs, tags, and so on. I don't think I've ever seen a plugin give me :%s and I'd be really surprised if it gave me \\{-}.

I think there's a lot of confusion when it comes to vim. It's an editor. Editors aren't just for writing and the real power of vim is editing. It's a major bonus that I can do all this with less resource consumption that just a plugin

Frequently using vim bindings in plugins leads to me generating gibberish.

I think I've seen sites trying to track outbound clicks recently, has prefetching made that impossible? I don't know the implementation but I've seen the browser sending requests that track clicks while investigating other stuff (idk whether it's working accurately though).

Edit: to be clear, it's not like I've researched this proposal since I don't work for social media companies. It's just a feature I wish I could have on my posts.

I don't have the fancier inverter style. Setting a power level still works pretty well even though flawed. Drawing the overall cooking time still manages to get things more evenly heated in the end when you give the food time to distribute the heat throughout the food.

Cooking food for 2 minutes at 50% power gives a noticeable difference in average temperature compared to cooking food for 1 minute at 100% power and waiting a minute.

And I don't always know what it decides to do as far as turning the magnetron on and off on its sensor modes, but it'll spend a while doing automated reheat and potatoes and what not and it'll be dang near perfect every time.

Don't get me wrong I'd love an inverter microwave, truly a better option. But its not like the duty cycle process has no impact.

LVTs focus is on maximizing land value, not profit. It just so happens that when a landowner maximizes the value a piece of their land provides, higher profits are almost guaranteed.

It's also a bit of a mistake to view LVT solely through an economic lense. Sure, we quantify it through a dollar amount or a difference in profits, but the value in LVT comes from how individuals value the land as a whole. So you are absolutely correct that a place without native vegetation, parks, playgrounds, etc. is going to be valued less than a place with those amenities by a lot of people. But only if people value greenspace and amenities more than pure economic output, which is mostly the case when it comes to residential spaces.

If people value greenspace, than the land around said greenspace will have a higher value. LVT would then incentivize those land owners to maximize their value, which would obviously include not destroying or removing the greenspace. Instead of would (likely) be to densify housing, or convert existing buildings to mixed-use spaces.

Is Pony still an actively developed language? I remember watching several talks while they brought the language up to release, and read several of the accompanying papers. However, I thought with the primary corporate sponsor dropping the language it had gone basically EOL. Which was a pretty large bummer as I was very interested to see how the reference capability model of permissions and control worked at large scale for concurrency control and management (as well as its potential application to other domains).

Great comment on hardware and maintenance costs, and in comparison Elon wrote "My estimate is that within 2 to 3 years, the lowest cost way to generate AI compute will be in space."
It's a pity this reads like the entire acquisition of xAi is based on "Elon's napkin math" (maybe he checked it with Grok)

Today was the second time in a year I went into one and my crotch got flagged because of my pants zipper. nothing in my pockets. no belt. nothing hidden. etc.

I was then subjected to full pat down and a shoe chemical test as a cherry on top.

Might need to try convincing them next time to let me do the metal detector instead.

What's the point of this higher fidelity scanner if it can't tell the difference between a fly and a restricted object?
