qwezxcrty | 3 months ago | on: OpenAI needs to raise at least $207B by 2030

I'm not really against your point but I just quickly checked (and it agrees with my personal observation), iPhone have been the very most popular phone brand in China for many years and recently the market share grew beyond 25%. I would not say that's not big enough to matter.

Yes, but even for people eligible for EB1A (it usually has a higher bar in practice, EB2/NIW is easier but way worse backlog), filing a (or according to some lesser stringent interpretation, having an approved) I-140, will make you have immigration intent and thus illegible for extension of any nonimmigration visa.

So you apply for green card and if you don't immediately get it (particularly because of the backlog for some countries), you have to leave the US.

(I'm not an immigration lawyer and these are only my personal interpretation).

If you are okay with less smart smart watches, and okay with no hackability, Garmin should have a few with black and white display and >1 week battery life (even indefinite with sufficient solar).

qwezxcrty | 6 months ago | on: Unofficial Windows 11 requirements bypass tool allows disabling all AI features

I just searched and it appears that contrary to what I thought, it is possible to individually acquire Windows 11 Enterprise (IoT or non-IoT) LTSC licenses from some redistributors.

The price varies a lot from suprisingly cheap ($7.7, is buykeysoft.com legit?) to a bit expensive but acceptable (~200 CHF). I'll definitely use these when I'm setting up my new desktop in the future.

Chinese have developed a significant amount of sophisticated tools countering internet censorship. V2ray as far as I recall is the state-of-the-art.

To use them, one need to first rent a (virtual) server somewhere from a foreign cloud provider as long as the payment does not pose a problem. The first step sometimes proves difficult for people in China, but hopefully Indonesia is not at that stage yet. What follows is relatively easy as there are many tutorials for the deployment like: https://guide.v2fly.org/en_US/

qwezxcrty | 9 months ago | on: TSMC bets on unorthodox optical tech

I guess they are doing direct modulated IMDD for each link so the DSP burden is not related to the coherence of diodes? Also indeed very short reach in the article.

qwezxcrty | 9 months ago | on: TSMC bets on unorthodox optical tech

I think the most fundamental reason is that there is no efficient enough nonlinearity at optical frequencies. So two beams(or frequencies in some implementation) tends not to affect each other in common materials, unless you have a very strong source (>1 W) so the current demonstrations for all-optical switching are mostly using pulsed sources.

Not an expert in communications. Would the SerDes be the new bottleneck in the approach? I imagine there is a reason for serial interfaces dominating over the parallel ones, maybe timing skew between lanes, how can this be addressed in this massive parallel optical parallel interface?

For a foreigner living outside of the US but interested in immigrating to the US in the longer term. Is it possible file the I-140, and while the application is being processed (or waiting for the priority date) apply for another nonimmigrant visa (B, F or J) for short term visit? Is it likely the application will be denied because of the "immigration intent" after filing the I-140?

In most but the very richest physics research groups there are no such thing called technicians. Except for shared equipment in centralized managed facilities like the nanofabs, even there you need to tune your own recipe...

That link was what I referred to after Googling, but in my case I need the width of the left part and the right part to be different, which requires setting width_ratios in the subplots and adjusting the slope of the hacky lines used to draw the broken axis symbol. seaborn also would not help in this exact case.

There is a package by some nice guy: https://github.com/bendichter/brokenaxes just to do the broken axis. But not being built-in in Anaconda is already an annoyance, and in my case it generates a figure with a ugly x-label.

I ended up letting ChatGPT generate the code for me with the two required hacks. I simply need the figure in the minimal amount of time and with the least mental bandwidth, so I can focus on the science and catch the conference deadline. Origin is a very "over-engineered" piece of software, but hey getting a broken axis is so simple (https://www.originlab.com/doc/Origin-Help/AxesRef-Breaks ). Sometimes the "over-engineering" is necessary to minimize users' pain.

I miss OriginPro in my undergrad when we had campus licenses for, before moving to matplotlib for data visualization. matplotlib is simply too disappointing for making publication quality figures. The most recently encountered problem is how to plot with a broken x-axis, which is one of the most basic need in physical science but requires a non-trivial amount of hacking to get with matplotlib.

Open source tool or not, I don't care at all as I get the science right. I have already enough frustration dealing with my samples, so I simply want the least frustration from the software I use to plot.

We use Compugraphics in UK at work for DUV masks (fused quartz 6inch) , base price for 700nm CD is much better than what the sibling comment predicts (sorry but I can't disclose).

qwezxcrty | 1 year ago | on: “A calculator app? Anyone could make that”

Tried with the HP Prime and it gave the precise 1 for the test. One need to put it in the CAS mode and use the exact form of 10^100 instead of 1E100. You shall get the right answer if the calculator is instructed to use its very powerful CAS engine.

A reason for that is the more and more hostile attitude towards Chinese working in the US and contributing to the US economy. The unfavorable birth place cap for EB1/EB2 green cards means even for the most elite Chinese students in the US need to deal with this toxic attitude for up to 7 years before they can finally wash out the suspection (or they can't?). Leaving US is the only option if they can't tolerate this.
