My workplace has two Windows 10 machines, one in daily use, and the other is mostly idle. Both are extremely slow. The one in daily use takes at least 15 minutes to become usable after boot. The other is not much better. They are domain-controlled so not much we can do to improve. In contrast, we still have a 20+ years computer, which has an IDE hard drive, running Windows 2000 with MS Office to operate an instrument, and it is much more responsive.
Thanks for the link! I didn't know they were using soda-lime glass and still call it Pyrex. In the meantime, the Pyrex labware remains real: I routinely pour liquid nitrogen into room-temperature Pyrex beakers without issue. That is a sudden temperature change of 220°C or 400°F.
> Imagine at the end of the American Civil War, a confederate army retreated to an island like Cuba or Hawaii, they took it over and have been calling themselves the real America ever since.
It is a great analogy. However, in this case, that small island was taken by China even before the American Civil War. To put it into perspective, it was during the time when Isaac Newton was working on gravity.
And one episode of Open To Debate [1] argued Taiwan is the worst possible place to confront China:
> I used to give battlefield tours at Gettysburg, an extraordinary place. ... a certain cavalry General John Buford ... surveyed the ground and he knew right away he looked at the hills and said, this is good ground, ... The geography favors us. Well, I want to tell you folks, he saved our country that with that appreciation. But this is the opposite. This is bad ground. This is the worst possible place to confront China
> Sextants can be read accurately to within 0.1 arcminutes, so the observer's position can be determined within (theoretically) 0.1 nautical miles (185.2 meters, or about 203 yards). Most ocean navigators, measuring from a moving platform under fair conditions, can achieve a practical accuracy of approximately 1.5 nautical miles (2.8 km)
Some napkin math, assuming using a Sextant to achieve similar accuracy of 0.1 arcminutes on the Moon, because Moon is about 3.7 times smaller than Earth, that 0.1 arcminutes is around 50 meters on the Moon. One can expect extremely clear sky and certainly not riding waves on the Moon, so the practical accuracy should be close.
Can it be self-hosted? Many institutions and organizations are hesitant to use AI because concerns of data leaking over chatbot. Open models, on the other hand, can be self-hosted. There is a deepseek arm race in other part of the world. Universities are racing to host their own deepseek. Hospitals, large businesses, local governments, even courts are deploying or showing interest in self-hosting deepseek.
They are self-hosted and require campus credentials for access. If you try to chat with the ZJU instance, it will redirect you to a login page. ZJU is unique in that it appears to support access from all higher education institutions in China.
> We are inclined to think that if you inherit almost the whole earth, you would be very grateful, kind and compassionate
That, perhaps, is the reason they are so cruel: because they have been so lucky so far, they do not understand human suffering and are incapable of feeling the pain of fellow humans.
I had similar problem on a ship with many users share a 2M VSAT Internet. Few tricks made Internet less painful:
- block windows update by returning DNS query for microsoft update endpoints as NXDOMAIN.
- use a captive portal to limit user session duration, so that unattended devices won't consume bandwidth.
- with freebsd dummynet, pfSense can share bandwidth equally among users. It can also share bandwidth by weight among groups. It helps.
- inside Arctic circle, the geosynchronous satellites are very low on the horizon and were blocked frequently when ship turns. I was able to read the ship's gyro and available satellites from VSAT controller and generate a plot to show the satellite blockage. It was so popular that everyone is using it to forecast next satellite online.
