Show HN: Lock as a Service 6 years ago
Thanks! I'll look into doing dynamic update. There is an API for this, I'll add some docs to the site on how to call it.

No. We’re still a long way from quantum computers powerful enough for that.
Current quantum computers are noisy. Gates aren’t perfectly implemented. Qubits are prone to dephasing and decoherence.
I like the Qiskit community textbook: https://community.qiskit.org/textbook/
Yes. Right now simulators tend to be faster, cheaper, and more accurate than real quantum computers.
That label is so long it’s breaking the HN front page layout for me on mobile.
any pair of students can be swapped if they both get a more preferred school.
This is the meaning of stable in the stable marriage problem. And the Gale-Shapley algorithm does this.
Foxconn to Build $10B Factory in U.S 9 years ago
The subsidy is $1.5B for 13,000 jobs. The other half of the subsidy is for capital investment and construction expenses.
It's still a huge number though.
Alabama. It says so near the very end.
The paper says they "adjusted for patient and physician characteristics" which presumably includes the patient's sex.
People also speculated that this was the reason Alphabet invested in SpaceX. (Which was around the same time as that announcement)

The AI isn’t used to directly grade the papers; rather, it turns grading into an automated, highly repeatable exercise by learning to identify and group answers, and thus treat them as batches.
It seems like the AI is identifying equivalent answers among respondents. So if you mark an answer correct on one test, every other test with the same answer will be marked correct. I worked for a small competitor of this product in college and we had a lot of trouble with this problem, especially with answers that were prone to spelling mistakes, or could be written in many ways. Kudos to them for doing this well.
Another fun bit of AI in this space is in identifying where the answer key might have made a mistake. We developed some algorithms for determining the most likely answer to a problem given the responses. We never released it but I worked on a tool that would grade tests without an answer key at all. Using 50 question tests in a few freshman physics classes I was able to get the right answer a little over 97% of the time.
Building 8 is the group.
(Zuck) announced the formation of a mysterious research-and-development group known as "Building 8."
