First, thank you for creating this project. When I was a young high school student in China, I tried all different kind of tools to evade internet censorship, including Freenet (al…

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 year…

VCSELs are lasers.

Okay, then it appears I have indeed overlooked this.

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 inter…

In that case some technical aspects needs rework... Currently O1 visa being a nonimmigrant visa have no path to PR/citizenship (unlike H1Bs) and need annual renewal. This make it u…

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 su…

Just morally I feel like MS do deserve to be compensated for me using what they developed, unless there is really no way to make it happen.

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…

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 …

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.

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 affec…

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 …

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…

This sound like a different interferometer for gravity wave detection (see LISA project), mostly for "seeing" stars instead of ground targets.

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, ev…

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 sub…

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 …

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).

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…

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 card…

On the converse, human nature languages do not necessarily follow Zipf's Law. Many asian languages including Chinese and Japanese are exceptions.

Lower noise for lower source impedances, to be slightly more precise.

If you look at the point of a Chinese, the block of Google/Facebook certainly can be justified by "geopolitical adversary has control". The exactly same reasoning of data security …
