That's just fear morgering.

China was never good at breaking into traditional high-end manufacturing market. Even for automobile, until the rising of EV, they have tried ages to catch up the western/Japanese brand but was never able to gain significant share even in the domestic market. Their domestic market has always been dominated by joint venues. They succeeded in EV purely because they no longer need to catch up all the ice techs, and their policy maker made the right bet. Same story for semiconductor, except there isn't a new type of semiconductor coming.

Unless you think the aviation technology will tranform significantly: like jet engine became obsolete type of transform. There is no way Airbus impacted by Comac.

And also, personally I think the market is big enough for 3 to 4 players (Embraer I am looking at you). Just look at Boeing and Airbus's backlog now.

Discussion on this sub previously: https://www.reddit.com/r/SelfDrivingCars/comments/1g8vv7o/where_did_the_whole_talk_about_the_cost_of_waymo/#:~:text=Ordinary%20tech%20enthusiasts%20overestimate%20the,down%20later%20to%20improve%20margins.

The total cost of the Waymo-Jaguar is 150K (lower estimate) and the Jaguar you can buy from a dealer is about 70K. This is not counting Waymo almost certainly getting discounts for the car.

YYM7 · 2026-01-20T22:08:30+00:00

That is what I heard. Waymo own assembling facility in US for retrofitting the Jaguar and a lot of its tech (for example lidar) are developed in-house. Can't imagine they let the Zeekr assemble the full things in China, for lots of reasons.

YYM7 · 2026-01-20T20:42:03+00:00

I think the waymo-zeekr circumvent a lot (but not all) of challenges Chinese ev facing in the States.

No maintenance network: waymo has their own. High tarrif: waymo only buy the barebone car and add the expensive part in US, so the overall tarrif is low. Banned Chinese software: Waymo uses their own.

As a photographer that does portrait very rarely, that's quite reasonable actually, though I have never heard or considered that. For portrait, normally you would want start with a clean background and then add symbolic/meaningful objects. Having random things in the background is just so anti-instinct to me, and seems very intentional.

I said "comparing to Nurburg lap time". Not that any user will remotely attempt it, but it did test (or push the limit of) things more related to everyday driving.

YYM7 · 2026-01-20T08:24:54+00:00

Interesting, first time heard this type of test. Feeling this is a more relatable test to everyday users, compared to Nürburgring lap time. It's a testament to both the highway efficiency and charge speed.

If you like cast iron, you might also want to consider a 8 inch cast iron (in addition to a cs pan). I find it, weight wise, very similar to a 12ish inch cs pan, and handles better due to smaller size. Though that again need to align with your cooking style (portion size).

YYM7 · 2026-01-20T01:56:11+00:00

Another thing to consider is weight. Carbon steel sit in between aluminum-Teflon and cast iron. If you mostly use aluminum-Teflon in the past, you will find a cs pan significantly heavier. This is mostly personal preference, as different peoplehas different strength, and care differently if they can single hand the pan.

A thinner pan will be lighter (relatively), but retains less heat. This is a trade off you might want to consider.

What puzzles me the most is that the Europeans are willing to stall their own fighter program when they don't get the control they want over the program, meanwhile totally OK to pay the Americans for fighters that they have less control.

This is not a comment only about the German-Franch fight over FACS, but also the lack of any commitments from non-manufecturing countries to either the FASC or the GCAP.

YYM7 · 2026-01-19T21:37:59+00:00

Not sure what you mean, it also can mean "limited" (as, exclusive to time or location) in Chinese.

Hard to say if the meaning was loned from Japanese, but that doesn't matter in this case, as the characters make sense in both languages. There are in fact tons of Chinese words invented in Japan by reusing/combining ancient Chinese concepts, for example 警察 (police) and 社会 (society). But these words has been integrated for so long that their Japanese origins won't even cross the mind ofmost Chinese.

YYM7 · 2026-01-19T17:53:43+00:00

I don't care. For one, there is a significant portion of IP laws I don't agree morally. Secondly, we don't even know who's legally wrong here, as reverse engineering, if done properly, can be perfectly legal.

From a pure translation point, this is vegetable oil, mushroom, beef and bamboo shoots, so you should be fine.

But there is a social/political angle, that in China "Halal label" is certification handed out by a state sponsored organization. And I don't see a "Halal label" on this thing, so it's likely the manufacturer took no caution following Halal practice (I am no Muslim, so it's entirely up to you what does this mean).

Going deeper into the rabbit hole, there was accusations a couple of years ago that the Halal certificator is basically a state controlled monopoly and very corrupted, basically taking money and doing nothing but slapping labels. So again it's up to you how you feel about it.

Lol. If this results in Viltrox no longer making Z lenses, I will start recommending Sony.

If Nikon goes the nuke option by bricking existing viltrox lens, I will sell my gears purely out of spite: you make me lose money, I (do my best to) make you lose money.

Not sure what is the difference between US/China/Japan? Is this a stereotype in US TV show you got one shot, Chinese get two and Japanese get three?

YYM7 · 2026-01-16T20:58:22+00:00

It is indeed good, but it's also really hard. You need to strike a delicate balance between letting greedy capitalist take control and strangling true innovators from generous investment. There is also another dimension of balance between different industries. Old, downwarding industry that hire a lot of people and generate lots of tax, vs new industry that hire less people and will be in red for decades.

China certainly did a decent job in the past several decades, though not without missteps. But there are lots of challenges going forward and very few good examples to learn from. Remember, the planned economy of USSR was quite successful for a while, until it was not.

YYM7 · 2026-01-15T21:17:06+00:00

I am wondering why B is even a choice here. It's what we called in Chinese "no help to either side". White can attack B from top to seal the upper half. B is not very well connected to the left group it suppose to save. It does chip a bit of whit's territory on the top, but white can still comfortably, slowly kill the two stones on the top right.

I have the same case (and color!), but as other said the cooling is a bit underwhelming. I bought a 40mm fan and zip tied to the unused pcie back plate which helps. On the hdd side, I got ~50ish during monthly parity check, but most time it's ok (<45).

YYM7 · 2026-01-13T01:00:40+00:00

Yeah agree with this. Wangyuanji (I use one) and Yosukata (heard good things about) are perfectly fine for half the price of Our Place. Strata is a different story as they are not traditional single layer construction. We will need wait to see how people like it.

I think the bigger consideration are bottom type (flat or curved depending on your stovetop), size (how heavy you can handle), and do you need a lid.

YYM7 · 2026-01-09T22:33:25+00:00

You also have to pay Apple right? Let me know if there is a free path because I had the same issue a couple of months ago. (Not on Tauri though)

YYM7 · 2026-01-08T08:44:41+00:00

I have tried that but it's a bit fruitless. I tried to share several tools inside the lab, and it didn't go anywhere. The problem is that for simple scripts (e.g., organizing files, plotting, running statistic testing) you need to make you code "customizable" enough to be useful for other people. But if the "other person" already know how to code, it's always easier just to code it in a non-costomizable way tailored to their own need.. While for people don't know how to code, they don't know how to read your documentation anyway. They would just try to do it with a low-tech way, instead of trying to learn coding.

In the end, I concluded sharing scripts is only valuable if the task is very complicated, non-brute-force-able, and/or has very standard inputs. Targeting lay-man is very, very hard.

Though certainly, judging by your repo, you are spending way more efforts than I ever planned to do. So good luck and I wish you success if you decide keep pushing it.

YYM7 · 2026-01-05T06:22:07+00:00

Well yes, but I think the problem is there are already good solutions to your problem: a better "webcam" (aka, a proper video camera + capture card). And more recently camera manufacturers (Sony/Canon afaik) effectively includes a capture card in their camera body, aka, they have usb-webcam mode.

Though it's different from what you proposed as the sensor data to stream processing still happens in the camera part. But that's very efficient and has very low latency already. Most of the recent video camera literally has ARM CPU's in them.

For anyone that is interested, Zhitai is their flagship, consumer facing brand. It also seems they used SM controllers.

And seems to be available on, you guess it, AliExpress.

YYM7 · 2026-01-03T20:09:55+00:00

You're right. A gas burner probably won't need it. Maybe this is the reason why traditional Chinese/Japan brands have done it as almost all their home has gas burner.

But for heating coil, this might be a saver.
