As a resident of Taiwan, would you say the average person there is comfortable obeying a strong central government, whoever that currently is? As an American, I found the deference to authority very strange.

> As an American, I found the deference to authority very strange. Are schoolchildren in the US still required to recite the pledge of allegiance...?

No, children can not be forced to stand and recite the pledge.

The Supreme Court ruled, in 1943, that it is unconstitutional to compel students to salute the flag and recite the Pledge of Allegiance.

China didn't get that way by magic. They ran the same playbook that allowed Alexander Hamilton to snatch manufacturing from Great Britain to the US, and the US gave up manufacturing for the same reason the UK gave up manufacturing (suppression of labor interests). It will be interesting to see what China does. They aren't ideologically committed to exclusively serving the interests of the wealthy, but they still have…

China and Vietnam are the only countries worldwide which have executed bankers for corruption in recent decades. No ahem necessary.

Communists have been executing bankers since day one so not just recent decades, if anyone finds that impressive.

This is still an ARM C1-Ultra. Same one used in Mediatek dimensity 9500, which also got more than 4000 points in GB6 lab test. But actual results inside phone with smartphone cooling and wattage requirement became close to 3300. But perhaps the most important thing, Xiaomi is now able to make chip similar to Mediatek. They are the third largest Smartphone manufacturer by shipment volume. And they are still growing. T…

The age old problem of mobile chips have brilliant performance for about 15 seconds until they thermal throttle. If you are just using apps, 15 seconds is more than enough to launch and setup an app, for anything more it will be down graded a little. Still dang impressive but the form factor becomes the limiting factor.

The browser can sometimes idle a lot until there is a touch/scroll event so it can be good for responsiveness during that kind of bursty stuff too.

They do allow to unlock their bootloaders, which is rather rare, which in turn allows to run Linux. Seeing as Chins just migrates their entire administration to Linux, it's not far fetched to assume they'll support Linux on their laptops very soon.

I'm not experience here, but are there any obstacle to move from "unlocking bootloader" to "running full blow linux on phone" ? I imagine it can't be that simple(mostly driver issue).

Lots of obstacles. The biggest obstacle is having access to the kernel sources. Even if you've got access to the kernel source, driver blobs are a big issue, because if you move to a newer kernel the old drivers may not work.

Take a look at the PostmarketOS Device Wiki[1], you'll see that even phones released 10+ years ago (like Xiaomi Redmi 4) still do not have 100% functionality.

In saying that, in this era of LLMs and reverse-engineering, it may not be long before some of these blockers are reverse-engineered and we might end up with a fully functional Linux distro on older phones like this.

MediaTek is a Taiwanese company. Xiaomi could put any backdoor that the government tell them to install and TSMC won't be able to catch that.

I'm unaware of any actual hardware backdoors introduced by primary manufacturers in practice, especially those installed in Xiaomi hardware. There are accounts of interdiction and post-manufacturing compromises, such as those revealed in the Snowden leaks (2013) and most recently by reporting about the Israeli security services' sabotage of Hezbollah pagers and 2-way radios. These projects didn't expose primary manuf…

What would you consider as good evidence of a backdoor? Apple got plenty of media coverup for their part in Operation Triangulation, and even hardware experts were defending it as a fuckup rather than a backdoor, providing it with great plausible deniability. Do you count it as evidence? If not, I can easily see any other company leaving these non-backdoors in their hardware with no damage to their reputation.

"Very happy" is a bit of a stretch, since a significant proportion of Taiwan would prefer to jettison the current pretence of being "One China" and become fully independent. But I agree that pretty much everybody will happily take the status quo over armed invasion.

I have a friend in Taiwan and he told me they're pretty happy because they have independence this way. If they go for more international recognition etc they'll gain nothing they don't already have but they'll upset the balance and give the CCP a reason to invade. So it will only make things worse. And a lot of people are sympathetic with the Chinese, just not their government. I've only visited Taiwan once and I onl…

>sympathetic with the Chinese

and related to, with all that holds in an Eastern mindset. My adoptive grandmother was born in Shanghai in 1927. To my knowledge she never returned to Mainland China, partially because her relatives wen Telswhere when the communists came in.

New CPU is 100% ARM design and nothing by Xiaomi other than "Chinese menu" configuration (i.e. how many blocks of this or that type,..). Apple CPU is a full custom design that just complies with ARM. Xiaomi Xring O3 CPU is designed by ARM and Xiaomi (as well as Mediatek) did not do any CPU design, other than custom bus interconnects, physical implementation on TSMC 3nm, an in-house NPU, and adopting next-generation L…

Everyone has to start somewhere, they achieve better performance than Tensor CPU on Pixel, to me that's an achievement.

There’s a big gap between spec’ing an SoC by configuration code, and designing one from the ground up.

That difference amounts to who, if anyone, gets the credit for being competitive with Apple.

The tension is killing me… who is the fast food joint?

I'm guessing Chick-Fil-A?

CFA franchises, but their program is very strict and requires an unusually high amount of upfront capital

You said it. It was over 100 F here where I live, and I was on my phone outside trying to get work done while watching my kid, and I couldn't even type because of the thermal throttling triggered just by it being so damn hot outside.
