Remember that the defender has home team advantage. That’s precisely what you see happening both in Iran and Ukraine. That advantage exists with Taiwan. There’s a reason that China hasn’t made a move in all these years, and the US is only one part of that equation.

Homefield advantage is relative, between Ukraine - Iran - Gaza, Taiwan is closer to Gaza, which is to say not much after mitigating outside spoilers. Maybe less than Gaza vs force disparity involved. US is/was one part of equation, but big part of equation.

That analysis requires discovering what the US’s objectives were. Not sure we can…

Discovering? It was announced a thousand times, maybe you dismissed because none of them were easily achievable?

Opening the Strait, renouncing nuclear program, renouncing ballistic program, regime change. Even Israel will be forced to retreat from Lebanon.

Iran won by choking the Strait and telling USA and Israel they could endure far longer than their aggressors could endure a few missiles and domestic support drop.

A Pakistani-made taco was not in my radar for today.


Opening the Strait was not a goal of this action; the Strait was open before this war started. They are trying to sell as a win a return to the status quo ante.

Right. So the objectives for US were regime change in Iran and end of nuclear program. Iran wanted sanctions dropped and continued nuclear program.

I think you will find that Biden closed the straights and that it was going to be reopened and China was going to pay for it. (/s?)

I dismissed them because the president and the Pentagon could not seem to articulate the objectives of the war in a way that was cohesive with one another.

Also,the Strait was open before the war.


Yeah obviously opening the strait wasn’t an objective. I think what you’re suggesting is that the mentioned reason - denuclearization of Iran - is unlikely to be the real reason, which may have been something like distraction.

> Opening the Strait

So the US started a war with an objective to open the Strait which only closed due to the war they started.

Can you explain what you mean here mate?


How on Earth was opening the straight an objective of this war, when the straight was open before the war.

It's like Russia declaring that Russian control of Moscow is an objective of the war with Ukraine.

> renouncing nuclear program,

If that was the objective, the US should be declaring war on the guy who scrapped the Iran nuclear deal, because it was accomplishing just that.


I explained the primary cause of this war here https://news.ycombinator.com/item?id=47684632

This war is happening today, to exchange a future nuclear war with Iran with a conventional war today. The US and Israel can fight a conventional war with Iran. They cannot fight a nuclear one. In a nuclear war, Israel would be destroyed by nuclear missiles in the two days. The possibility of a nuclear Iran is an existential crisis for Israel, and Israel will do anything possible to prevent Iran from gaining nukes.

That is why we have this conventional war happening today, (with unclear goals), to prevent a nuclear one in the future.

This war was unavoidable btw, it was going to happen sometime this year or next.


> This war was unavoidable btw, it was going to happen sometime this year or next.

Iran was, as per the latest reports I've read, complying with terms and not enriching uranium to weapons-grade or close to weapons-grade. Are there credible reports suggesting otherwise?


Those reports are old. IAEA inspectors have not been able to access any of Iran's nuclear facilities since the start of the 12 day war on June 13, 2025. Currently, nobody knows what Iran is doing with their nuclear material.

If only there was an agreement in place to help with that. Oh wait, that got canned by someone when started this nonsense.

What do you make of Netanyahu claiming that Iran was weeks from a nuclear bomb, 20-30 years ago?

What do you make of US/Israel assassinating the supreme leader that had declared a fatwa against nuclear weapons?

> This war was unavoidable btw

Wars of choice, thousands of miles away from the nearest US city, are extremely avoidable, and don't let anyone tell you otherwise.


This is fantasy with no real evidence to support this view.

Although it might reflect actual considerations of Israel and, by extension, the US, that's ultimately a very unreasonable take. Iran might not have been trying to build nuclear weapons in the past, as they claimed. Maybe they did, maybe they didn't. In contrast, Iran will try to build nuclear weapons in the future with certainty. They'd be insane not to try now, after having been bombed for weeks in an illegal war of aggression against them and having been threatened with massive war crimes and genocide.


The main one was stayed to be regine change. That didnt happen

Some might argue that the US's (or the POTUS's) objective was simply to disrupt the financial markets.

And that benefits them… how?

Not sure, but any event, positive or negative, will benefit those who know the exact timing in advance.

This sounds like goalpost moving. Like if you fail to acheive regime change, just say whateber the consequences of your failure were had been your objectives from the start. According to "some" who might "say"

You speak like you and I discussed this before, and you remember where the original goalposts were.

Many analysts suggested that the attack was a smoke-and-mirrors, and the actual goal has always been financial. Similar to the tariffs story. According to that opinion the outcome of the attempt is irrelevant. Regardless of whether the regime have changed or not, the goal is still achieved.


"Some", "many analysts"

Come on man. The goal was regime change. They said its regime change. They were chasing the high of the maduro kidnapping. But then they ended up replacing Khamenei with Khamenei like they replaced the taliban with the taliban in afghanistan. Its fucking embarrassing


Well if the objective was just about distracting from some domestic issue, then maybe it doesn't matter from Trump's perspective.

The objective was to let Hegseth act out his Crusader fantasy and kill some Muslims.

The key here is “could be”. But most four (or in my case, six) year olds can’t really grasp the abstract concepts of what JWST is or the data it’s sending back. For that matter most 40 year olds can’t.

A manned mission on the other hand is tangible in a way a probe isn’t. “See the big round thing in the night sky? There are four people going around it in a spacecraft”.

It isn’t a _complete_ argument in favour of manned missions- that has to account for the risk of the endeavour and reward of the science potential of having people there to react in ways robots can’t. But it’s hard to pretend that the inspiration pretty much everyone feels when they see manned missions is somehow achievable purely by robotic ones.


They’ve changed it so III isn’t landing. That will be IV apparently.

Hi, CEO of Mindgrove here!

Good to see that we're being noticed. But we all still need to deploy (in scale) to make anything worthwhile.


Best of luck Shash! Been following you guys since your IITM days!


It _is_ RISC-V Vector extensions, so a very specific ISA in mind at the very least. There's another extension (not ratified I think) called Packed SIMD for RISC-V, but this isn't about that.


The name, yes, but going by name is a bad idea as the V in AVX also stands for Vector. BTW, you'll be disappointed if you think of the P extension as something like SSE/AVX. The target for it is way lower power/perf, like a stripped-down MMX.

My point was about the underlying hardware implementation, specifically:

> "As shown in Figure 1-3, array processors scale performance spatially by replicating processing elements, while vector processors scale performance temporally by streaming data through pipelined functional units"

Applies to the hadware implementation, not the ISA, which is not made clear by the text.

You can implement AVX-512 with smaler data path then register width and "scale performance temporally by streaming data through pipelined functional units". Zen4 is a simple example of this, but there is nothing stopping you from implementing AVX-512 on top of heavily temporaly pipelined 64-bit wide execution units.

Similarly, you can implement RVV with a smaller data path than VLEN, but you can also implement it as a bog-standard SIMD processor. The only thing that slightly complicates the comparison is LMUL, but it is fundamentally equivilant to unrolling.

The substantial difference between Vector and SIMD ISAs is imo only the existence of a vl-based predication mechanism. If a SIMD ISA has a fixed register width or not, allowing you to write vector-length agnostic code, is an independent dimension of the ISA design. E .g. the Cray-1 was without a doubt a Vector processor, but the vector registers on all compatible platforms had the exact same length. It did, however, have the mentioned vl-based predication mechanism. You could take AVX10/128, AVX10/256 and AVX10/512, overlap their instruction encodings, and end up with a scalable SIMD ISA, for which you can write vector length agnostic code, but that doesn't make it a Vector ISA any more than it was before.


> The name, yes, but going by name is a bad idea as the V in AVX also stands for Vector.

Now I get your point after reading more of the linked page. Yes. It is very implementation specific.

One of the things about RVV (and in general any vector ISA) is that the data path can be different enough between different implementations such that specific rules of thumb for hand tuning most probably won’t carry over. As you say it is true of even sufficiently advanced SIMD architectures like AVX.


Stripped down MMX? What's left then I wonder? :-D


That was a bit overblown, due to my lack of knowlage about MMX. It has a lot more things than MMX. But the core idea behind the P extension was to reuse the GPRs to do SIMD operations with little additional implementation cost.

The spec is currently all over the place, the best reference is currently probably the WIP intrinsics documentation: https://github.com/topperc/p-ext-intrinsics/blob/main/source...

P is not meant to compete/be an alternative for RVV. It's meant for hardware targets you can't scale RVV down to.


> But the core idea behind the P extension was to reuse the GPRs to do SIMD operations with little additional implementation cost.

I think ARMv6 had something similar, before they went with proper SIMD in v7.


As sibling said, stripped down in the sense it doesn’t have dedicated registers. In terms of supported functions it’s somewhere close to MMX.

I don’t personally like it because it still ends up with all the headache of building most of a vector subsystem (data path, functional units,…) while _only_ pretty much reducing one special vector file.


Technically it’s a retroflex approximant [1] and is found in many places (often not as a separate character or phoneme).

But I think we’ve hijacked a cultural thread with enough phonetics for now!

[1] https://en.wikipedia.org/wiki/Voiced_retroflex_approximant


I'm coming around to the idea that we _should_ really be using "l" or maybe "r" instead of "zh" for the ழ. At least it's closer in pronunciation and there's a chance someone can work their way to it. Zh is like "we don't have an exact match so we'll repurpose a letter we don't use". It has no phonetic relevance.


Tamil is my mother tongue and I agree 100%. And like insisting that sentences shouldn't end with a preposition, or "you should say GNU/Linux, not Linux", it's no way to make friends and influence people.

Whenever someone says "actually", it's hard not to think of https://www.youtube.com/watch?v=dGvw-E4OtOA


Sure, referencing a meme in a language relate discourse, should make people take you seriously /s

Rules for thee, but not for me :))))


Yeah I shouldn't have posted The Office meme. My bad. Unfortunately it's too late to edit my original comment.


All good :)


I think the decline of manual transmission is different from self-driving. Manuals, you could argue are a technological progression that doesn’t change the fundamental economics or sociology of driving. But self-driving has issues far beyond the technology. Like liability, like ownership of vehicles, availability, traffic rules,…

I’m not even sure if, outside of highly mapped environments it even makes sense.


Or it collapses when the seniors have to retire anyway. Who instructs the LLM when there’s nobody who understands the business?

I’m sure the plan is to create a paperclip maximizing company which is fully AI. And the sea turned salty because nobody remembered how to turn it off.
