It's adorable. One small criticism: instead of being stored as initial conditions with no internal forces, if the tooling allows for it it should be stored as the "relaxed" state with internal forces. As it stands, the first interaction with it causes the whole model to 'bump' because everything is actually just kinda hovering in space with no physics simulation happening and only the first interaction causes physics calculations to start.

> Wouldn't some of these costs be present either way?

This is a fair way to account for the cost, because the assets were procured and personnel hired years ago for just this purpose.

Put another way: we would not need this fleet at all if we did not expect to use it in a manner like this. (For example, Spain did not choose to have this capability and so has not borne a cost of maintaining this option for the preceding decades.) Through that lens, the true cost of this war would involve counting back to before this round of hostilities began.

It's only fair to count _at least_ the "time on task" for all the assets.

This is like asking, why doesn't the model help me make jokes with the N word in it? It's a product of a business in a society. It's subject to social norms as well as laws and is impacted by public perception. Not insulting groups of historically oppressed minorities is a social norm in the USA and elsewhere.

One of the ways this makes its way into the model is the training data. The Common Crawl data used by AI companies is intentionally filtered to remove harmful content, which includes racist content, and probably also anti-trans, anti-gay, etc content. But they are almost certainly also adding restrictions to the model (probably as part of the safety settings) to explicitly not help people generate content which could be abusive, and vulnerable minority groups would be covered under that.

Unconscious bias is a separate issue. Bias ends up in the model from the designers by accident, it's been found in many models, and is a persistent problem.

> My understanding is that they were actively negotiating

The only parties I’ve seen say this are Iran and Oman. Practically every other source, including non-English, concedes taking three weeks to come close to hashing out a framework isn’t serious.

> Trump was not authorized by Netanyahu to win that negotiation

This is nonsense. Netanyahu was pushing Trump. But if the Tehran team had capitulated, Trump would have taken the win. Hell, the capitalization could have been bullshit.

> outcome was foreordained

Of course it wasn’t. Ford wasn’t scrambled until weeks ago.

If you can read translated European, Indian, Chinese and Arab reporting on this, I’d strongly suggest it. The English-language stuff has inherited America’s obsession with Israel. That’s obviously germane here. But it isn’t as controlling as we like to make it seem.
Low-entropy tokens tolerate substitution with and 0.1 PPL cost across models
by Trinicode | 2026-03-03 20:15:37+00:00
I investigated whether an explicit entropy signal in token embeddings—beyond implicit frequency effects—carries independent information in modern LLMs, and if it could enable inference optimizations in frozen models.

Using skip-gram trained 260-d vectors (256 semantic + 4 entropy dimensions) on FineWeb-Edu, I projected them into GPT-2 and Qwen3-14B embedding spaces and substituted low-entropy tail tokens (rare/predictable, function-like) vs high-entropy common tokens (frequent/polysemous).

Surprising result: Low-entropy tail substitutions incur a near-constant +0.101 to +0.102 perplexity increase on both models—to three decimal places—despite major differences in architecture, dimension (768 vs 5120), tokenizer, and norms. This appears intrinsic to the token class.

High-entropy tokens are far more sensitive: +36 PPL on GPT-2, +9 on Qwen3 from ~500–530 swaps (per-token ratio 356× → 91×).

Residual stream analysis shows nearly identical mean convergence trajectories, but low-entropy tokens exhibit transient mid-layer variance spikes (heterogeneous paths), while high-entropy ones propagate perturbations monotonically.

Native training on Qwen3 subword vocab weakens the signal (narrower contexts) and reverses the pattern.

Repo with reproducible experiments: https://github.com/maykef/entropy2vec

Results summary (tables): https://github.com/maykef/entropy2vec/blob/main/results/summary_table.md

Conclusion: The low/high-entropy distinction is real and model-agnostic, but post-hoc exploitation for inference (speed/memory) is negligible on frozen models—lookup/forward pass remain full-cost. Meaningful gains would require conditional compute from pretraining.

Curious about similar observations in larger models or alternative uses (e.g., uncertainty detection, curriculum design).

Not competitive at all. It's easily visible on the laptop lines, where the same GPU manufactured on TSMC has 3 times the power/performance ratio compared to the Intel one.

Putting more cores is just another desperate move to play the benchmark. Power is roughly quadratic with frequency, every time you fall behind competition, you can double the number of cores and reduce the frequency by 1.414 to compensate.

Repeat a few times and you get CPU with hundreds of cores, but each core is so slow it can hardly do any work.

I ran the qwen 3.5 35b a3b q4 model locally on a ryzen server with 64k context window and 5-8 tokens a second.

It is the first local model I've tried which could reason properly. Similar to Gemini 2.5 or sonnet 3.5. I gave it some tools to call , asked claude to order it around, (download quotes, print charts, set up a gnome extension) even claude was sort of impressed that it could get the job done.

Point is, it is really close. It isn't opus 4.5 yet, but very promising given the size. Local is definitely getting there and even without GPUs.

But you're right, I see no reason to spend right now.

Yes, and this has been the case for years. Cnet, ZDnet, PCmag have been user-hostile since long before AI summaries. Pop-ups, “before you go,” back jacking, all the worst.

The Verge is a surprise because it is relatively new and was relatively free of this crap for a long time.

They’re all just empty brands now. They totally caved to advertisers, and now only advertisers care about them.

I dare say AI’s popularity is a symptom of all this more than a cause.

Tell me you don't know how US legislation gets passed without telling me you have no idea how legislation is passed. I agree Democrats have been failures at what they've attempted to do. But it's a cop out or disingenuous to say both sides have had enough power to make meaningful changes.

How often has either side had a filibuster-proof majority in the last 30 years? Once. Democrats had it in 2009-2010 for 72 working days. During that window they passed the ACA sans a public option thanks to Joe Lieberman. They have not had an opportunity like that since. And we live in a time when Republicans explicitly state they will do everything they can to oppose a Democratic president. Even filibustering their own bills.

Now take a step back and consider what each party is actually trying to accomplish and the mechanisms available to them. Budget reconciliation only requires a simple majority, but it's limited to taxing and spending. Tax cuts, the core of the Republican agenda, fit neatly into reconciliation. They don't need 60 votes for their top priority.

Democrats' goals... expanding healthcare, strengthening labor protections, voting rights, are substantive policy changes that don't fit reconciliation's rules. They need 60 votes they haven't had. So when you say "both parties enabled the wealth gap," what you're really describing is a system where one party can pass tax cuts for the wealthy with 51 votes while the other needs 60 to do almost anything about it.

Some of my M1 MBP Max keys are losing their coating, and the battery is at 74% capacity. At some point soon I'll need a service. But other than that, I have no real complaints. Even the case edge where my arms constantly rest doesn't look too bad.

My next MBP will have 128GB memory, but these prices just wanna make me wait longer.

The cost doesn't really matter. The US led financial system (which is a glorified Ponzi scheme) is on an unsustainable path. The war in Iran is about resources (force Iran to use US dollars to trade oil, give US more leverage in dealing with China...etc.) and to delay the collapse. You build "digital pyramids" like AI data centers and consolidate power/resources while you still can. Financial cost of the war is largely irrelevant. Whether the outcome will be to your advantage is a different issue but pattern is predictable with historical precedence (Romans...etc.). Unfortunately innocent people pay the price.
by Quarrelsome | 2026-03-03 20:16:53+00:00
because when you give someone the keys to the US military to some people, they lack the imagination to think beyond piracy and raiding.

The war in its current inception is Hamas levels of planning.

1. Do a big attack

2. ????

3. Profit!

Depends of if the Iranian state is weak enough to collapse on its own, because I imagine a land assault in Venezuela or Iran would be a horrific mistake due to the terrain.

Bold of any greenfield project to choose Electron in an era when RAM prices have quadrupled in only 6 months, and are likely to remain at nosebleed valuations for years to come.

Must be nice to willingly “price” yourself out of a market that is quickly becoming desperate for low-RAM-usage apps, and not care one whit about it.

Lemons do happen with Apple Silicon.

I had a Mac Studio that would kernel panic on a semi-weekly basis. Apple Care put me through the reinstall OS / remove all external devices tap-dance for weeks, insisting that hardware was the last thing to suspect - before Apple Silicon, kernel panics were almost always hardware, particularly RAM.

Ultimately I bought another Studio and swapped it in - kernel panics went away. With that evidence, Apple acknowledged the problem and exchanged my Studio for another one from the factory. I returned the swap unit within the 30 day window, so it didn't cost me anything but annoyance.

I have max, I kept hitting usage limits. I have 4 projects that I will code in parallel, so while one agent is working, I spin up other agents to complete things. Most of my effort now is designing agile roadmaps with specifications, epics, sprints and implementation cards (using AI to create it, then reviewing it), so the Agents have a massive, detailed roadmap. I review code but I also built a framework where much of the code is generated by templates not the model itself so the review is mostly cursory.
Show HN: Livekit-monitor – self-hosted monitoring dashboard for LiveKit
by jossephus01 | 2026-03-03 20:17:59+00:00
I built livekit-monitor this weekend after needing better visibility into our self-hosted LiveKit instances.

LiveKit Cloud has great monitoring tools, but I couldn’t find a lightweight option for self-hosted deployments. This project is a small Rust + React app (single binary) that lets you track: rooms and participants, session history, egress and ingress activity and etc.

Repo: https://github.com/jossephus/livekit-monitor

It also ships as a small Docker image (~21 MB).

If you run self-hosted LiveKit, I’d really appreciate it if you'd try it out.

Thanks!

No, they're not selling this as an "AI accelerator":

Here is the quote:

"The company says operators deploying 5G Advanced and future 6G networks increasingly rely on server CPUs for virtualized RAN and edge AI inference, as they do not want to re-architect their data centers in a bid to accommodate AI accelerators."

Edge AI usually means very small models that run fine on CPUs.
Show HN: A tool to give every local process a stable URL

In working with parallel agents in different worktrees, I found that I had a lot of port conflicts, went back and forth checking what incremented port my dev server was running on, and cookie bleed.

This isnt a big issue if running a few servers with full a stack framework like Next, Nuxt, or Sveltekit, but if you run a Rust backend and a Vite frontend In multiple worktrees, it gets way more complicated, and the mental model starts to break. That's not even adding in databases, or caches.

So I built Roxy, which is a single Go binary that wraps your dev servers (or any process actually) and gives you a stable .test domain based on the branch name and cwd.

It runs a proxy and dns server that handles all the domain routing, tls, port mapping, and forwarding for you.

It currently supports:

- HTTP for your web apps and APIs
- Most TCP connections for your db, cache and message/queue layers
- TLS support so you can run HTTPS
- Run multiple processes at once each with a unique URL, like Docker compose
- Git and worktree awareness
- Detached mode
- Zero config startup

My co-workers and I have been using it a lot with our workflow and i think it's ready for public use.

We support MacOS and Linux

I'll be working on some more useful features like Docker compose/Procfile compatibility and tunneling so you can access your dev environment remotely with a human readable URL

Give it a try, and open an issue if something doesnt quite work right, or to request a feature!

A couple weeks ago I was working remote and didn't bring a power adapter, and I realized a couple hours in that my battery was getting kind of low. I clicked on the battery icon and got a list of what was using a lot of power: 1 was an hour long video chat using Google Meet, the other was Claude desktop (which I hadn't used at all that morning).

What in the world is an idle Claude Desktop doing that uses so much power?

CI/CD has a “missing primitive”: toolchain + OS-level dependency management. We treat deps as “npm/pip/maven”, but then glue the real environment together with Homebrew/apt-get and end up with Bash embedded in YAML.

This issue argues that’s how you get commit-driven development: the only place the full environment exists is CI, so the feedback loop becomes commit → push → wait → read logs → repeat.

The piece maps the spectrum from asdf/mise (version pinning) → Devbox (shared dev shell + runnable tasks) → Nix (declarative, reproducible build graph), with a practical thesis: if you make the environment a first-class artifact, “local-first, reproducible pipelines” stop being aspirational and start being achievable. Includes a scorecard and concrete examples of flake-based CI patterns.

Mostly getting stuff done on the Windows machine in the next room or playing music off a different stereo or playing music on cassette tape or minidisc on the same stereo, etc. It's easier to fall back to a world of 20th century electronics where latency is imperceptible than it is to dive into a world of third-party apps that were all designed around somebody's inscrutable KPIs but didn't consider at all my convenience or inconvenience. Probably it is Creative Cloud updating or some software for the mouse or some kind of crap and if I sat in front of the machine for 30 minutes it might settle down but it's rare that I sit in front of it for 30 minutes. It used to be that kind of thing wrecked the Windows experience but over a long period of time Microsoft did a lot of work to balance to load of startup processes and mostly you don't feel it.

My wife browses the web a lot on that Mac, she hasn't complained since I installed Firefox + uBlock Origin but maybe she expects it to be slow.

Well, it's easy to pick a half-n-sphere corresponding to a point on the surface. You just take the half-sphere centered at that point. For our two-dimensional circle, it would be the arc defined by the diameter that is perpendicular to the radius running between "the point" and the center of the circle.

At that point you've lost the ability to say that only one such half-sphere defined by a dropped point can be a valid solution, and you've also lost the ability to say that if a valid solution exists then there must be a valid solution defined by one of the points you want to include in the half-sphere, but you can define a canonical half-sphere for any point.

I was uncomfortable with the idea of picking "random points on a circle" to begin with, because of https://en.wikipedia.org/wiki/Bertrand_paradox_(probability) , but the article doesn't even address whether the concept is well-defined. We can always choose a point on the perimeter deterministically from any chord (...that isn't a diameter), so the ill-definedness of the problem of choosing a random chord seems like it would infect the problem of choosing a random point on the perimeter.

This project is not real.

It's 100% AI generated slop and is non functional. Zero people can verify it works, the creator refuses to show evidence or videos of it working and looking at the codebase shows very clearly it's using mock data and has no functionality.

This is a valid criticism. Whenever there is a push to improve life for US citizens, we are told that we do not have the funds. Yet, here we see an essentially unlimited budget to fight Israel's war of aggression against Iran, with zero benefit to US citizens. In fact, the costs (financial, moral and human) that we will pay for this excursion will be astronomically high.

I bought an LG Ultrafine 5k at the time and felt kind of stupid for being spending on it. But nearly 10 years later... its still my daily driver. Best ROI of any tech equipment I've bought. It changed my mind about how to think about it, not just the monitor, but having speaker / camera / mac built in, and all over one cable, its been such a joy when I bounce around the house to be able to plugin / unplug so easily; or when I swap from work to personal laptop. Its such a simple setup. Im definitely considering the Apple one, basically regardless of what it costs, once its time. Its simply been too convenient to have a one-plug solution for the laptop that has everything I need, never breaks (my LG may be exception here lol), and that has somehow taken forever to be super ceded by something better.

Only thing that holds back that thought lately is, I'm suddenly spending more and more time in multi-pane terminals, and my screen real estate needs have dropped. The only two things I greatly miss now on my laptop is keyboard quality and general comfort (monitor height, etc).

It's for building embedded Linux distros, and your typical Linux distro contains quite a lot of C++ and Rust code these days (especially if you include, say, a browser, or Qt). But you have parallelism across packages, so even if one core is busy doing a serial linking step, the rest of your cores are busy compiling other packages (or maybe even linking other packages).

That said, there are sequential steps in Yocto builds too, notably installing packages into the rootfs (it uses dpkg, opkg or rpm, all of which are sequential) and any code you have in the rootfs postprocessing step. These steps usually aren't a significant part of a clean build, but can be a quite substantial part of incremental builds.

So what? Any LCD also struggles with black levels. They have advantages and disadvantages. The point is more that Apple tries, like TV manufacturers, to hide the LCD designation by instead coming up with a creative but misleading acronym. "XDR" in this case. This never happens with OLED. Which shows that manufacturers believe that most people care more about black level contrast than maximum brightness.

Facebook absolutely sucks I am not saying that it doesn't. I agree with you on that one.

But what I am saying is that Google might be better in that regards given that they didn't try to pester in and backstab like how OpenAI did. The bar is low but yeah...

That being said, even if these weren't these companies. To tell you the weirdness of the scale we are in here. A company spent 80 million $ on Ai.com and then their budget of where the site was hosted was free cf worker tier...

So a lot of market is essentially just kind of weird even now, This might be the biggest move by any AI company and the best investment to hire OpenAI employees en-scale. Perhaps Anthropic can do that too as I mentioned it earlier.

Imagine a company, which gave a place of employment and used talent of the engineers whose conscience denied OpenAI and the ones who wrote notdivided.org

These companies absolutely exist imo and as such, Money isn't a concern to OpenAI employees and neither should it be.

Atleast that's my opinion. Training and GPU costs for AI companies cost in magnitudes of several millions. To give a few several million dollars to get some good AI researchers doesn't feel so far fetched to me.

As such OpenAI employees shouldn't be worried about money. And they do hold leverage over OpenAI far more.

Atleast that's my opinion but I am curious to hear yours.

Ditto, I don't see myself upgrading in the near future, the 64GB M1 Max I paid 2499 at the end of 2023 still feels like a new machine, nothing I do can slow it down. Apple kept OS updated for around 6 years in Intel times, I don't see how they can drop support for this one tbh. I'm still paying for apple care since I depend on it so much
