I don't really understand the author's conclusions about cost and shipping, and how RISC-V is cheaper and more accessible to people outside the US and Europe. He first talks about how getting $1 worth of chips can cost $60-$200 in shipping for him due to his location... but then by the end claims that RISC-V gives him "an architecture that arrives in my country at ten cents a part". I don't get how both things can be…

He's saying that shipping from the big western parts suppliers (Digikey, Mouser, Segger) costs a lot of money. When ordering from AliExpress or Crowd Supply he just gets the cheap postal rates which from China are free. It is very likely a good chunk of the overhead from western part suppliers has to do with export controls and risk aversion. Aliexpress doesn't do any ID verification hassle. This is all an argument m…

Aliexpress doesn't just sell RISC-V parts... I've purchased dozens of STM32, GD32, nrf52 parts from Aliexpress and LCSC.

Appeals to an ethical basis don't work on everyone

Let’s take the rationalist approach, then: does the author of this blog post seem like someone who could contribute reasonably to humanity’s future? Does it seem like we might be doing ourselves a disservice by ignoring them, and those like them? “I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton field…

I'm on your side, the comment I was replying to seemed to assume that the gp commentor was motivated by or at least interested in ethics.

>He derives the case for the chip and then spends the rest of the article annoyed that the chip exists. >This is almost satirical. That's all that needs to be said. It's like comparing Unity and Godot. Unity is better in every single way but one, you have to license it from a very poorly ran company. You don't "own" your games, they ship with black box spyware. The pricing for using it can change from day to day. I s…

I'm not a professional game maker. But having used unity in anger in the past I found Godot a breath of fresh air. What unity really wins with is the unity asset store.

Yeah, I saw that, I wasn’t taking a shot at you.

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 diverg…

I assume the 3am-9am figure was in US Pacific time, in order to emphasize the difference from the working hours of people on the US west coast.

Sure, but that's 12-18pm CET, which is hardly peak EU work hours.

So what does "the majority" mean? 51%? Because that's just saying those 51% occur during EU/UK afternoons and east cost mornings.

High shipping costs are the reason why many countries in the Caribbean and Latin America usually have freight forwarders They locally market themselves as package lockers, po boxes or online shopping companies. It turns out the expensive shipping cost doesn't scale linearly with package size or weight. The expensive shipping cost is a base price, and only rises slowly with package weight and size.

So, these freight forwarders rent a warehouse in the US, an LLC in the US for paying rent, and give away the address of the warehouse to their customers locally. Customers use the address when shopping online and their packages are dropped off at the warehouse. Then they employ people in the US to collect customer packages in the US into large bags, which are then shipped to the destination country via DHL.

DHL does charge the exorbitant shipping to third world country fees of 35 to 60 to 200 dollars that people here complain about. These fees are the base price for shipping, no matter how small or light the package is.

Then, to recover the fees, packages are handed over to customers at a minimum of 2.50 dollars per pound, per package.

For the business to work, income from these packages has to exceed the shipping cost. In Panama, you can probably fit 100 average packages into a 25 pound bag. That bag costs like 75 dollars to ship from the US to Panama. Then you make 250 dollars when people collect the packages. Local customers trade speed for cost, trading the 35 dollar base shipping price for 2.50 dollars and an extra week of lead time to wait for collection to complete in the US. They also don't have to go to the airport to pick up their packages since the business is ideally close to their house.

Businesses like Temu ship directly from china via companies such as PRS logistics and J&T express so their shipping costs to third world countries are lower and can thus bypass freight forwarders entirely so freight forwarders only remain for items sold within the US, where shipping to third world countries has a base price of at least 35 dollars, and whenever shipping to your country costs that much as a base price, even if it ships from China, or when a business only offers shipping to or within the US.

Sometimes, temu is more expensive than a Freight forwarder, but the user is freed from having to handle any logistics like using a particular address and choosing and registering with a package locker and travelling to pick up packages there and the shipping price remains under 10 dollars. However you still have to use a Freight forwarder for items over 120 dollars such as laptops and some car parts because temu doesn't carry those. Freight forwarding is also done in the exact way described above in China instead of the US because websites like taobao rarely offer overseas shipping. Again employing people in china and renting warehouses near airports there. Freight forwarders also offer marine freight instead of the default air freight.

Of course, renting a warehouse and employing people in the US is expensive by local standards. Worker pay alone is around 1600 dollars vs 600 locally. So, there are only a few freight forwarders which often offer b2b, and then package lockers use their sevices. To the end customer there is no distinction between a package locker and freight forwarder. Some freight forwarders also offer B2C package locker services, others are B2B only.

For example nelcon cargo, Uno express, airbox, mail boxes etc are vertically integrated because they are both B2B and B2C, cft cargo is B2B only. most package lockers do not do freight forwarding themselves and use a B2B service for freight forwarding, the package locker only offers proximity and thus convenience to neighborhood customers. Air freight via Miami international airport is the default, and most freight forwarder warehouses are located near this airport. In China, the bottleneck is not price, but speaking Chinese, so it is often run by locals of Chinese descent and is more niche than shipping from the US. This also means that taobao has a lower shipping volume and thus a smaller local market.

Buyee and Zen market, so called proxy services, are very similar to freight forwarders but the service is allowing foreigners overseas to purchase in Japan because most japanese companies do not offer overseas shipping. And there are a few freight forwarders in china as well.

> 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"

That might be a local thing, Hong Kong being a British colony means there's plenty of people in the UK for whom Asian means Chinese.

Here are a few random things I know of: * Tenstorrent Ascalon has a neat optimization for certain LMUL>1 SIMD operations. LMUL=2 effectively unrolls the SIMD operation making it read two SIMD registers from every source and write two SIMD registers to the destination. There are however some instructions where LMUL=2 only needs to write to one registers, those are narrowing instructions (e.g. 64-bit to 32-bit truncati…

How do you keep up with such information? Any sources you could recommend? Closest I know would be SemiAnalysis

Every SemiCon usually has a RiscV forum. Obviously there are also RiscV events. Wesemibay usually has several RiscV processors and GPU's from new vendors and you can then go and check what features they support. But basically as with everything else you have to show up and talk to people, or just look at the summaries afterwards.

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

When the term started out, There was nothing called United States (As a country or its current culture/s). And I am not sure if this happens outside the US anyway.

Still interesting, even so.
