You can search `known_hosts` for a fingerprint using `ssh-keygen -l -f ~/.ssh/known_hosts` and `grep`. If you disable `HashKnownHosts` in your ssh config, the command will also tell you the name of the host(s) for that fingerprint

You will be happy to learn that under Chair Khan, the FTC is going to prioritize enforcement actions against this specific practice. Only 1 Commissioner issued a dissenting statement. [1] Comcast has probably already discontinued the practi

The "inflation targeting era" began around 1995 [1]. The official story explaing how 2% became an (informal) international standard is kind of interesting [2]. [1] https://www.stlouisfed.org/-/media/proje

Hamming is great in general. Some years ago, I picked up a copy of "Numerical Methods for Scientists and Engineers" for like $2 at a used book store. I had no idea who Hamming was, but it was cheap so I bought it. After the first

The formula for error bars under the traditional Binomial assumption is: +/- sqrt(p * (1-p) / N) So the errors are around +/- 1% for most values of p in this article. The article (rightly) points out that the binomial

In nvidia land, `nvidia-smi` is like `top` for your gpus. If you're running compiled CUDA, `nvprof` is very useful. But I'm not sure how much work it would take to profile something like a pytorch model. https://develop
