I think he's kind of speaking past the original author. The original piece is basically about how the author doesn't think that RISC-V will take off outside embedded, because of some design decisions that lead to poor performance compared to ARM64 and because so much of the ISA being optional means that there's too much fragmentation to make binary distribution feasible. Meanwhile, this piece is mainly about how RISC-V is great for embedded because companies can build it into custom chips with specifically the functionality they need, and because of how cheap it is for low-end use cases since there's no license fees.

The only real point of contention I see between the two is that this piece goes on to talk about how it's a selling point that RISC-V can be used for both low-end 10 cent microcontrollers, and high-end multi-core processors running Linux. Personally I don't see the benefit of this since you're going to have to recompile your software anyway, and since all the RISC-V SBCs I'm aware of have significantly worse performance and efficiency than comparably priced ARM SBCs.

The huge number of companies building RISC-V chips and really crazy optimizations that they are doing in all kinds of spaces are a very real counterweight to your notion.

And RISC-V is just starting here with shoestring design and fab budget. Wait till all engineering teams really adopt it like Tenstorrent and NextSilicon and so on.

> Personally I don't see the benefit of this since you're going to have to recompile your software anyway

The benefit is a unified toolchain. Make a chip, get the entire software toolchain for free.

In the past if you made your own chip you had to write your own assembler, compiler, debugger, etc. Many manufacturers forked gcc but of course it's still a lot of work and the license isn't great (for them, not the user).

This universal compiler toolchain is massive benefit for both the chip makers and the end user.

Different RISC-V dialects might as well be as different from each other as English is from German. Sure, the cognates, family the resemblance, and common(-ish) alphabet make some things easier, but if you're shipping a manual, you still need to do it both in English and auf Deutsch unless you rely on machine translation.

So it is with the family of mutually incomprehensible ISAs called RISC-V.

He says:

> From that position, the difference between a ten cent part and a one dollar part is not a rounding error and it is not a detail you get to wave past on the way to the interesting discussion about encodings

Yet earlier:

> I pay anywhere from US $60 to US $200 to ship one dollar chips that people everywhere else get free shipping on

Seems to me that the difference between a 10c chip and a $1 chip are a rounding error when the shipping cost dominates so much?

I’d really like an explanation here if the author is reading. And how does shipping cost scale with quantity? Can you get that to be small per unit on big orders?

I don't think the Author disagree with what the original article wrote. If anything everything he said seems to reassert what the original article intended to state.

And while things has died down a lot in the past few years, there is a reason why I wrote the line.

"You do not criticise The Rusted Holy Grail and the Riscy Silver Bullet."

I love the article, it's a breath of fresh air compared to the usual bay area centric takes. However there's just one issue:

> The students I want to teach are in the same position, and so are the ones in Nigeria and Bangladesh

It does not take $60 to ship small sub $1 chips from Asia to Nigeria/Bangladesh. These two countries are all on global trade routes (both supply and demand) and the expensive last mile delivery costs are fairly low there too.

This is a bay area centric take on a non bay area centric take.

The typical bay area centric take has the following vibe:

1. I am among the group of most open minded people

2. I admit mistakes, but I don't change my view, that means I may make the same mistakes next time on a different concrete cases

3. Morally I am among the least corrupted

4. I work for the moderately morally questionable firms with nice paychecks, but my moral views are not tainted a bit

5. I never think on the other's perspectives

As exemplified in the following series of essays

https://www.astralcodexten.com/p/the-foothills-of-bay-area-h...

This one was more self-aware than others. But we all know the demon voice of San Francisco sounds like a shoggoth trained on LessWrong.

Thank you so much for sharing these. I just laughed my ass off a bunch, and I’ve only yet read this one latest post in the series.

My favorite bit, I think (along with the running gag of the constant use cases/connections that somehow pop up for Epstart’s founder):

> “Would you like to hear more about how copying AI tics helps me keep conversations going?”

> “Uh, sure - wait! No!” You break off and turn around as fast as you can.

If the other entries in the series are anywhere near as good, I’ll have some reading to do now.

Is this comment on shipping costs from Asia to Nigeria/Bangladesh based on your experience? If there is a less expensive way then share the approach to help others :)

i don't know how trustworthy rateships.com is, but according to them shipping costs to nigeria and trinidad are similar. and as for the last mile, the cost probably goes up because local shipping is rather unsafe (higher rate of theft of packages).

It could be bureocratic barriers. For example, Turkey recently changed importing laws so that anything(even stuff sent to you for free) from outside the country is subject to tariffs & import costs. Importing a cheap component worth 1$ costs like 300$.

> It does not take $60 to ship small sub $1 chips from Asia to Nigeria/Bangladesh

So don't even try to find how expensive is bring these to Brazil. Even the $5 orders from JLCPCB become infeasible for hobbyists here due to all the roadblocks.

> from Asia to Nigeria/Bangladesh.

Bangladesh is a country in Asia...

I am in Asia, this means nothing, it's the largest continent on earth. I don't pay as much for shipping as the author does, but his struggles are nevertheless relatable: most sellers refuse to ship here, most of those who do want dozens and dozens of dollars for it, and some (few, usually Chinese) sellers save the situation from being completely hopeless.

In my experience, people in the United States often (incorrectly) short hand East Asia as Asia just like the people in the city of New York will often (correctly) short hand New York City as New York.

It's an interesting evolution given that Asia as a term started out meaning just the westernmost tip of current-Asia, ie Western Anatolia.

Slight correction, people in NY refer to it as “The City” and people in NYC say the same, but specifically mean Manhattan.

> In my experience, people in the United States often (incorrectly) short hand East Asia as Asia just like the people in the city of New York will often (correctly) short hand New York City as New York.

In my experience, the only demographic who complains about “Asia = east Asia” are people from South Asia, aka Indians/desis

Ironically (for my generation in the UK at least) "Asian" meant "South Asian" and for a long time we didn't have a useful shorthand for "all parts of Asia"

We aren't the only ones, but we are the loudest about it, because erasure sucks.

Don't get me started about Macedonia.

So is Ireland.

I don't think they are necessarily asserting otherwise

So what does it mean to ship from Asia to Bangladesh? Do you ship from India, Iran or Indonesia? Or just within Bangladesh? :)

Shipping from Asia to Asia doesn’t make much sense

Asia is a pretty big place

Compared to a banana?

>HN hasn't been Bay Area centric in years. Honestly, most comments and usership on the platform seems to now align with DACH.

I honestly do not get this at all. HN remains very US-centric to me, and especially centric to the mindshare of the Bay Area's IRL conversations, and apart from some takes on tech rights, does not really remind me of my experience in DACH.

As someone from the DACH region I very much agree with this. I don't see a shift from typical US opinions to opinions often held in the DACH region. Not at all.

> HN hasn't been Bay Area centric in years.

>> HN remains very US-centric

Bay Area != US

The Bay Area is its own microcosm of culture and philosophy that diverges significantly from much of the US.

Not making a statement on how prevalent either are on HN, but Bay Area is very much not equivalent to the US.

As an American, it’s extremely Silicon Valley centric, at least in mindset.

Extremely. The valley/startup lens is absolutely the dominant one.

> I honestly do not get this at all. HN remains very US-centric to me, and apart from some takes on tech rights, does not really remind me of my experience in DACH.

The majority of HN's usership, posting, and comment activity occurs during peak EU work hours (3am-9am), stylistic patterns that are common for German-native speakers are increasingly prominent, and the fact that IRL conversation topics in the Bay Area tech scene are entirely different from those on HN shows a massive divergence in userbase.

HN "Who wants to get hired" threads are a good example of that as well.

I'd recommend deep diving in the HN scrape dataset on HuggingFace [0]. The site has diverged heavily compared to 2018 or 2012.

[0] - https://huggingface.co/datasets/open-index/hacker-news

How would you say the "IRL conversation topics in the Bay Area tech scene" diverge from HN?

While I appreciated your source 1.) I doubt 99% of Europeans work during 3am - 9am 2.) At least there can be other reasons: 2a.) EU times and African times are basically the same and Africa has a huge population. 2b.) India is closer timewise to EU/African time zones 2c.) What are about posts afterworks?

" RL conversation topics in the Bay Area tech scene are entirely different from those on HN shows a massive divergence in userbase. " Any proof?

Non-American here... what is DACH?

It is Germany, Austria, Switzerland.

Thanks! I must admit this is the first time I have heard of the acronym.

Based on https://en.wikipedia.org/wiki/International_vehicle_registra...

Germany, Austria, Switzerland (D, A, CH)

" HN hasn't been Bay Area centric in years. Honestly, most comments and usership on the platform seems to now align with DACH and CEE. "

I like to encounter discussions about German digital health system or the German start up system or neo2. I've never seen them so I doubt it.

Also almost no debates about Polish stuff (Hello neigbours!)

How is it not tech bro centric when every third thread is about some new feature of a random Anthropic product?

> this place is like a memory of the forum we used to love, and the memory is fading.

Well, this place (wherever you are) is like a memory of the world we used to love, and the memory is fading... Definitely true too.

You can't expect a place tightly connected to a changing world to stay the same.

So, you are calling the author a liar?

Nice read!

Though it feels a bit strange that "I have exceeded the allowed number of requests. (500 times)" when I first clicked the article and I'm pretty sure I don't share the ip of my self-hosted VPN with anyone.

I think it’s telling the site owner, not us.

Working archived copy - https://archive.is/9FaRC

Is archive.is still a malicious site that DDOS's finnish security bloggers or has that been sorted?

To me it feels like the difference in positions is "this could be made better" vs. "but this is already so much better than before". Both are right.

Maybe I'm missing something important so far...

I was thinking the same. RISC-V is certainly impressive and I'm glad we have it, but the original article isn't wrong in its complaints either.

It definitely could have gone with a less abrasive tone (as entertaining as it is), so it's no wonder it's getting some pushback.

Yeah the complaints in the original article are valid, but it's like complaints about Android or iOS. There are plenty of valid complaints against either, but neither is strictly better than the other.

This is the sort of content I endure this place for. Thanks for posting.

"Now price the same journey on the other side, forget x86-64 and that duopoly, patent minefield, with multi-thousand dollar debug probes; we'll take a look at ARM."

The 386 and 486 patent should have expired more than 20 years ago. No one tried to open source it. https://github.com/EI2030/Low-power-E-Paper-OS/blob/master/0... There were many companies that had clones in the early 90s, and I wonder whether any of them still have the rights to manufacture them.

" That is a better reason than elegance. and I want to tell Mr Grinberg, that the word priviledge he tosses around in his article also extends beyond the ISA depending on where you are in the world."

Grinberg is an emigre from Ukraine, which isn't the most privileged place in the world. In fact his research articles go deeper than the average software developer in Silicon Valley.

There are 386 and 486 open source reimplementations in Verilog (see z386 and z486). As far as I know, existing commercial 386/486 chips still manufactured (yes they exist!) are descendants of Cyrix work, not Intel or AMD. Consequently, VIA may be contractually holding those back rather than Intel/AMD doing anything there.

Thanks for that information! I have been interested in getting x86 produced in smaller nanometer (e.g. <32nm). My project: https://ei2030.github.io/FemtoTX/#about

Edit: It also appears Nvidia might also have an x86 license: https://www.nvidia.com/en-us/drivers/uli-m6117c/

Also, https://www.tomshardware.com/pc-components/cpus/intel-licens... (Caveat: The startup is acquainted with the Intel CEO, so it's rare for them to grant the x86 license to non-buddies.)

"Intel provided Rosaic access to an unknown Atom-class core, which enables the company to build its own custom processors based on x86 general-purpose cores, according to the report. The renowned chipmaker plans to ship Rosaic register-transfer level (RTL) code for the Atom processor core, which will let the startup build its custom system-on-chip (SoC) both at Intel Foundry and elsewhere."

What's interesting is that a startup with limited funds would most likely seek a 32-bit x86 license if a) they don't need more than 4GB of RAM, and b), if they don't want to pay AMD for the 64 bit license add-on. :)

I have no idea what's going on here, but the title alone gave me second-hand engineering stress. Solid post.

Absolutely hugged to death.

Original HN discussion referenced:https://news.ycombinator.com/item?id=49298035

This blog post is very defensive and argumentative, which I guess is fair considering Dmitry's post is similarly inflammatory, but most of it was really not convincing:

> Simply put, the things a high-end CPU needs are diametrically opposed to the things a small cost-saving microcontroller core needs.

> The conclusion he draws is that no single ISA can serve both ends, and that RISC-V fans are fooling themselves, in theory the premise is true. The conclusion does not follow, and I can show you why from three parts sitting on my desk as we speak.

> CH32V003. This is the cheap "RV32EC" with sixteen registers, no multiplier, no divider, machine mode only,

> CH32H417. A dual core MCU that is unmatched in performance to price point and is at the higher end of the MCU line

> Baochip. A VexRISC-V with an MMU built around a stack thats open from silicon to os Baochip-1x: A Mostly-Open, 22nm SoC for High Assurance Applications

Uh, which one of these is a datacenter server cpu? Or a workstation cpu? Or at least a developer laptop cpu? How about a Raspberry Pi 4 level SBC (supporting latest ubuntu and fedora releases, driving a display that runs a browser and plays video ...)

There's a lot of angry indignation but it seems obvious that Dmitry is quite right about this.

But I found this is where this blog post starts making a lot of sense:

> Has anyone tried adding an MMU to a Cortex-M? The physical tradeoffs are real, the difference is that with RISC-V, the ISA owner does not decide for you where that boundary must be drawn. If you want virtual memory on ARM you license a Cortex-A instead, which is a different core family, a different profile, a different negotiation, and a different royalty.

> Compare what happened with Baochip. The RISC-V privileged specification defines supervisor mode and Sv32 paging as optional things an implementation may provide. VexRISC-V is an open core, somebody added an MMU to it. bunnie built a chip around it and runs a microkernel with real process isolation on it

Yeah, that is a good point. We're still in the low-end specialty realm, but that is real interesting advantage for RISC-V, a good reason for it to exist.

As for shipping to Trinidad and Tobago ... this post is trying too hard to turn this into moral issue, but it seems a bit random (OrangePi cost $30 and shipped free? you can also get arm-based and stuff from the same places), and the vast majority of people don't live on semi-remote islands, it doesn't make sense to consider this kind of accessibility above all else, and it's strange to blame Dmitry for not thinking of you here.

More than half the article is AI slop. Sad.

"Rate Limit Exceeded"

Does anyone have an archive?

The author of the article just got a fan.

Some serious stuff he builds on top of those chips.

Just an unlucky spawn point. We need to focus on ourselves. "oh no shipping to some remote island is expensive compared to NYC that has next day free on everything" Well, duh.

So “you were born somewhere ‘unlucky’, that’s how it goes, sucks to be you”.

Is that really your take?

Naïve take. We live in a global neoliberal economy, our standards of living are the direct result of introducing scarcity and other forms of exploitation elsewhere while keeping domestic populations largely unaware of how unfair their position is. There is no ethical basis to simply "focus on ourselves" here. We must do the exact opposite.

Appeals to an ethical basis don't work on everyone
