ssh -X doesn’t work out of the box for my 20.04 host. It was solved after adding X11Forwarding yes and X11UseLocalhost no to /etc/ssh/sshd_config at the host. btw, one great way to debug the problem is to turn on the verbose flag. i.e., ssh -vX hostname
I got confused over time of coordinate transformation for a point in space v.s. transformation of a point location with fixed coordinates. It turns out that the former is the exact reverse of the latter. I don’t include a proof here, but it should be self-evident. Also it is much easier to understand coordinate transformation…
As titled. Tried to follow the guide from here. Have some problems running realsense camera. The guide from jetsonhack is okay. But cannot find pyrealsense2 in python. Adding pythonpath solved the import problem but the imported package contained no method. Copying all so files (pybackend2.cpyton-*) to the working folder seems to resolve the problem. The…

Try to avoid overheating with this. Haven’t tested enough to see if it is really working well.
Just played with it a bit. So far my experience is horrible. Nvidia is notorious for poor support in software. I think this one is especially unacceptable. First, I really don’t understand why the installation can be so complicated. I need a host computer connected to the device with a USB cable emulating a network…
A talk by Professor Mearsheimer 6 years ago explained very well the motive of Putin. https://youtu.be/JrMiSQAGOS4A First, the point usually missed by everyone is that NATO is a nuclear power and it is hard for Russia to swallow a nuclear power adjacent to it. So Russia reacted so violently as Ukraine tried to join the…
My X1 Yoga gen 3rd died after I used in outside freezing. The battery died completely and it crashed the hard disk as well. After I replaced both, touch screen does not work but stylus is half functioning. It doesn’t work near the bottom edge. I originally suspect the battery. But I used the UEFI…
I use dropbox to manage my website. It is not really very secure. But it is at least very convenient. I use one dummy dropbox account contain just my website folder shared from my main dropbox account. Then I just login dropbox with my dummy account for my web server. It has been working…
