Awesome! It looks like we could extract the depth from the video, but my knowledge of ffmpeg is too limited for that. Do you know a way to do it?

Really nice! I would love to add all my notes here, but I sometimes needs to include images, and this is a blocking feature for me. Any plan to include that? A really nice to have would be to have inline Latex mathematical formula, but it m

A short optional sample of every composers and songs would be nice, just to get an idea of the music. I can't remember music in my head (kind of Aphantasia for music), so it's really hard for me to choose just from the list.

What about using machine learning? It sounds like a discovery issue, and recommender systems work very well for that (eg. the side bar of Youtube). I just discovered Neocities BTW, it sounds very interesting!

It doesn't have a good accuracy. I have yet to see a real-life dataset where it's better than to just call LogisticRegressionCV from scikit-learn. For bigger datasets, you may use vowpal wabbit or Fasttext. It may be a little bit

Does anyone have a good book for advanced linear algebra? I learned the basics in school - eg. Matrix diagonalization, svd) but I need for ml to really understand things like angle between flats, tensor decomposition, etc

My main issue with R^2 is that it is an artificial indicator. It has no business meaning. The best alternative is to build a metric that is related to your business issue. How many $ do you loss if you're wrong by 1%? Or by 10 units? D

Great idea! Some questions: - Both R and Python support strings, factors, and complex objects in a dataframe. What is NOT supported by feather? - Feather is "not for long term data storage". Will it be standardize in a distant fut

How do you handle strings on hdf5, on an efficient and portable way? I didnt find any convincing answers.

Genuine question, why do you find Pymc3 better than stan? Pymc3 is still in alpha, while Stan is stable since many years. They both implements the same algorithm (NUTS), so is it just the nicer syntax or is it anything else?

Please modify the bindings, the directional keys are international, without a qwerty keyboard I can't play - and no, I will not modify it systemwide for just a JS game. Nice one nevertheless!

I just saw a tweet of Notch > Turns out unrolling tight inner loops really speeds them up! 38% speedup from that alone. Makes sense, it's doing one eight of the branching https://twitter.com/notch/status/59

Please don't make it configurable, because it will mean there is no longer "a" YAPF standard. Also look at Pycharm reformat tool, it would be a shame if both couldn't be used in the same versionned project.

One useful feature is to consider the neighbors rows, for example for differentiating a time series. Do you plan to make an efficient method for that?

Minecraft online also have all the properties you cite, and there are even more options, collectiond, and human interactions. Think about it: the other players can be adversary or allies, and that can change whenever you want.

This is the bad part of HFT, the one that is theft and destroy value. It is paid by the big players, and "solved" by imperfect solution like dark pools. A better solution could be to add a hour component to the order, so all comma
