Do they all live at the same address of the overseas freight forwarder too? I've sold stuff on eBay to someone in Europe who had me ship to the same address in Delaware. I was confused so I googled the address and turned up the freight forwarding service.

reminds me of that Hunter S. Thompson quote from Fear and Loathing in Las Vegas, "Not that we needed all that for the trip, but once you get locked into a serious [solar power setup], the tendency is to push it as far as you can.”"

I always felt that part of the interview process is the candidate asking clarifying questions as well as making and stating assumptions.

CrowdStrike is not a vanilla userspace program, it hooks deeply into the operating system.

The Probabilistic Bisection Algorithm by Horstein, original paper is "Sequential transmission using noiseless feedback," IEEE Trans. Inform. Theory, 9(3):136–143. https://ieeexplore.ieee.org/document/1057832

Here's a nice presentation on an analysis of the method, references start on slide 47

https://people.orie.cornell.edu/pfrazier/Presentations/2014....

Paraphrasing the theorem from Jedynak, Frazier, Sznitman (2011):

Suppose [flake probability] is constant, known, and bounded away from 1/2, and we use the entropy loss function. ... The policy that chooses [next test point] at the median of [current posterior distribution] is optimal.

And some python code that implements a version of the analysis

Even if it is real, odds are it’s complex.

I'm not going to argue with your central point that we spend too much time scrutinizing small dollar awards. The PPP program was ridiculous. I had a very difficult time helping two legit non-profits (one a nursery school, one a food pantry) get a fraction of the money they were entitled to under the PPP program, while less scrupulous people got far more.

In the EB-5 real-estate investment program, the government doesn't hand out money here. If you're a rich overseas individual who wants to relocate to the US, you can invest like $1-2m (used to be lower), and boom you're in.

According to Wikipedia, "Slurm is the workload manager on about 60% of the TOP500 supercomputers." I have used it as a job manager front end for most computational clusters in the last 10 years or so.

I was just thinking about this at lunch today! I have been working through the Advent of Code 2020 problems. Day 20 involves a very simple version of the reassembly problem, putting together square tiles with fixed size overlapping border patterns. I did the first phase of the challenge "by hand," but I was wondering how fast it would be with the recent advances in CNNs and Transformer models.
