The decision to shorten "cybersecurity" or "cyberattacks" to "cyber" alone is so annoying!

All models are "cyber-capable" :P

I recently tried buying a domain in cloudflare, they refused the payment -- even using my account which I use actively for years -- tried to pay with paypal, no luck. Went to porkbun and bought the same domain in 5 minutes and pointed it to cloudflare name server.

Maybe they should fix the regular flow before automating it with agents?

Does it produce real svgs as opposed to foreign object html in svg mess that mermaid compilers produce?

Well, the paper explicitly takes the principal branch to solve this.

So it isn't exploiting the branching for computation.

Exactly! If you didn't strictly limit the operator's complexity, you could just smuggle a Turing machine in via bitwise logic and turn the whole thing into a parlor trick. The beauty here is that eml(x,y) is a pure, continuous analytical function with no hidden branching whatsoever.

To clarify my earlier point: the author isn't trying to build a practical calculator or generate human-readable algebra. Using exp and ln isn't a cheat code because the goal is purely topological. The paper just proves that this massive, diverse family of continuous math can be mapped perfectly onto a uniform binary tree, without secretly burying a state machine inside the operator.

I think the point here is to explore the reduction of these functions to finite binary trees using a single binary operator and a single stopping constant. The operator used could be arbitrarily complex; the objective is to prove that other expressions in a certain family — in this case, the elementary functions — can be expanded as a finite (often incomplete) binary tree of that same operation.

In other words, this result does not aim to improve computability or bound the complexity of calculating the numerical value. Rather, it aims to exhibit this uniform, finite tree structure for the entire family of elementary expressions.

This is a very in depth graph compression research presented with unmatched visuals. Trully inspiring and mind blowing.

2swap produces the type of content that makes me genuinely happy about existing :)

To be clear I never said custom vibe coded personal software is bad. But clearly that's not the point from OP. Quoting directly:

you download a skill file that tells a coding agent how to add a feature

This is suggesting a my_feature.md would be a way of sharing and improving software in the future, which I think is mostly a bad thing.

Why would this new paradigm create interesting tooling? From your description I expect wrose not better tools.

I did some more reading and want to walk back my skepticism a bit. There is actually serious effort going into this, such as Google’s research on space-based AI infrastructure: https://research.google/blog/exploring-a-space-based-scalabl...

They highlight the exact reliability constraint I was thinking of: that replacing failed TPUs is trivial on Earth but impossible in space. Their solution is redundant provisioning, which moves the problem from "operationally impossible" to "extremely expensive."

You would effectively need custom, super-redundant motherboards designed to bypass dead chips rather than replace them. The paper also tackles the interconnect problem using specialized optics to sustain high bitrates, which is fascinating but seems incredibly difficult to pull off given that the constellation topology changes constantly. It might be possible, but the resulting hardware would look nothing like a regular datacenter.

Also this would require lots of satelites to rival a regular DC which is also very hard to justify. Let's see what the promised 2027 tests will reveal.

How are you doing pci express x16 with lasers without fiber optics? Have you touched data center hardware in your life?

Haha, hard pass on the job. I prefer my oxygen at 1 atm.

I'm not a data center technician myself, but I have deep respect for those folks and the complexity they manage. It's quite surprising the market still buys Musk's claims day after day.

Car-grade inference hardware is fundamentally different from data center-grade inference hardware, let alone the specialized, interconnected hardware used for training (like NVLink or complex optical fabrics). These are different beasts in terms of power density, thermal stress, and signaling sensitivity.

Beyond that, we don't actually know the failure rate of the Tesla fleet. I’ve never had a personal computer fail from use in my life, but that’s just anecdotal and holds no weight against the law of large numbers. When you operate at the scale of a massive cluster, "one-in-a-million" failures become a daily statistical certainty.

Claiming that because you don't personally see cars failing on the side of the road means they require zero intervention actually proves my original point: people who haven't managed data center reliability underestimate the sheer volume of "rare" failures that occur at scale.

Maintaining modern accelerators requires frequent hands-on intervention -- replacing hardware, reseating chips, and checking cable integrity.

Because these platforms are experimental and rapidly evolving, they aren't 'space-ready.' Space-grade hardware must be 'rad-hardened' and proven over years of testing.

By the time an accelerator is reliable enough for orbit, it’s several generations obsolete, making it nearly impossible to compete or turn a profit against ground-based clusters.

AI clusters are heavily interconnected, the blast radius for single component failure is much larger than running single nodes -- you would fragment it beyond recovery to be able to use it meaningfully.

I can't get in detail about real numbers but it's not doable with current hardware by a large margin.

Only people who never interacted with data center reliability think it's doable to maintain servers with no human intervention.

I made a comment earlier that was rightly flagged for its tone, and I would like to restate the technical point more constructively.

The post author, Dan Piponi, clearly knows about fractals, but his post raises the question of whether asking Fermi questions in interviews is actually effective. I am skeptical that such questions would have prevented this type of bug.

I suspect the issue stems from small measurement imprecisions accruing over long distances, which is—in my view—tied to the fractal nature of roads traversing natural landscapes.

However, as others have pointed out, it may also be tied to road closures: if closed segments are set to a higher length internally (to discourage routing), these values might be getting summed up blindly over longer distances.

None of these issues would have been prevented by being good at estimating quantities alone.

Apologies again for the unconstructive tone of my previous comment.

My bad. My intention was not to come across as snarky or aggressive.

Dan Piponi, in his post, called for scale questions in interviews, suggesting that whoever worked on the feature at Apple would not have been hired if they had been asked those types of questions.

I found that position non-constructive and wanted to counter it by mentioning that fractals could hint at why the length was so large.

It is hard to predict how others will read my comment beforehand, and I apologize for not meeting the friendliness bar here on Hacker News.

Not really, if you had every grain of sand in the way it would diverge to a much bigger value. The problem is that the roads have >1 dimension at that scale, apple maps is definitely adding up to many details along the way, it's not a straight line and it ends up being 10x the actual distance. No Biggie.

The "fix" is to smooth those details as the straight line distance grows bigger.

This video is truly remarkable. I'm so grateful to artists like 2step for sharing this kind of work on YouTube. It reignites a passion for math that many of us might have forgotten, especially those of us who have been away from formal math education for a while.

It's understandable to hold different perspectives on the video. However, simply dismissing it as "AI" without any supporting evidence or referring to the audio as "noise" is unproductive and doesn't foster a constructive discussion.

It's funny because you can't measure borders due to the coastline paradox.

Strong agree, they can even make the formatter configurable in pyproject if you want to use something else.

Anthropic also uses TPUs for inference.

That seems exactly why it happened.

Why should a platform allow sharing ways of violating its terms of service? Sure, any tech savvy person will be able to figure it out, but business are businesses.

Should supermarkets allow you to ressel coupons in their premises for a profit? Because he's 1. monetizing the video, 2. being sponsored by a third party in the video and 3. showing ways of circumventing the platform TOS.

He could remove that frame where he shows the yt plugin, but he's using this to farm engagement.

On top of that, there is no easy way to create a template

Templates are just functions [0].

I think much of the frustration comes from typesetting being a harder problem than it seems at first. In general a typesetting system tries to abstract away how layout is recomputed depending on content.

Supporting contextual content -- cases where the content depend on other content, e.g. numbered lists, numbered figures, references, etc -- involves iterative rendering. This is evidentidly a complexity sinkhole and having a turing complete script language will bite you back when dealing with it. I recommend reding their documentation about it [1] where they explain how they propose solving this problem.

I am not on mobile. It all boils down to the way decade old convetions/expectations are broken.

The things that look like buttons (and are spans in the html code, not even anchors!) trigger non-local transitions (the left panel thing) when hovered... and they close the opened panel when clicked, so if I move my mouse to click on it the end result is a panel that flashes.

I need to keep ignoring the usual button affordance of being clicked and force myself to think they are tiggered on hover.

If this isn't bad UX I don't kown what it is.

I can't agree more. Linus position here is not dissimilar to CEOs and alike. He's trying to deal with R4L using his (allegedly) 100% technical and 0% political perspective but in this case it simply doesn't work. R4L is a political challange that require political discussions; who decides? what's the bar? who maintains what? etc

By not answering this questions and saying he doesn't want to have anything to do with the arguments, Linus simply decided that he doesn't want to solve the problem that only him can solve. The result is clear: R4L will fail if Linus decides that any maintainer can stop the "cancer" to spread and block Rust changes.

R4L implies that Rust will be present in the kernel and will need to be maintained. If Linus is ok with maintainers that have a deep/fundamental problem maintaining/coordinating the maintenance of Rust code, R4L will never happen.

Really solid program. I bought a license years ago because it is the only software that correctly remuxes media for direct play in Chromecast, including surround sound and HDR.

I wish Jellyfin could catch-up with the compatibility level AirFlow has to offer.

There seem to be a latch mechanism to keep it attatched. I would be surprised if it was designed to rely solely on magnets.
