Haha the good old circular dependency problem. I am still surprised there are people in the industry that can’t recognise and solve these problems. It is such a classic pattern and its use arises in the wild all the time.

by alex_smart 2y ago
Sure, but use of those patterns is not idiomatic in Python.

THIS right here is why I use emacs. Not that something like this is not possible with other open-source software, but the number of steps required to compile, debug, identify change required, compile, rerun, it is usually not worth your tim

Almost all programming tutorials and even books to a certain extent suffer with the problem of terrible examples. Properly motivating most design patterns requires context of a sufficiently complex codebase that tutorials and books simply d

On mac, iterm2 has excellent tmux integration. You start tmux in control mode (tmux -CC) and it opens a new window for that session with all the multiplexing handled by the terminal instead. You get to use all of your normal terminal keyboa

by alex_smart 2y ago
Consider evaluating an expression like "col1 + col2 == col3" A tree based evaluator has to do something like - for (int i = 0; i < df.size(); i++) { // switch on expression type (column, binary operator,

I found this by looking at spark source code to figure out what they were doing under the hood to deal solve this problem. :)

I recently implemented my own expression evaluator in java for in-memory data frames, and once you think about doing that deeply, you very quickly understand the need for bytecode. If you directly evaluate the expression using a tree repres

One thing that wasn't mentioned in the article that I wished it did was the size of the compiled binary with and without final. Only reason I would expect the final version to be slower is that we are emitting more code because of inli

In case you didn’t know, doesn’t delete the commit. You can use `git reflog` to find the commits you were recently on and recover your code.

Not sure if you’re being facetious? There were not 100 people of the same calibre as JvN in the US or even the world surely.

Probably not. The figure is the right order of magnitude.

I meant 3 tries in total, not just the random guesses.

by alex_smart 3y ago
Excellent work! We can also probably prove that 3 guesses are not enough by some sort of adversarial argument. That is, instead of having the color be fixed at the start, imagine that the game picks the colors adversarially to try to make t

by alex_smart 3y ago
Assuming the score is 100-Euclidean distance, you should be able to triangulate to the correct answer after three random guesses. Triangulation will give you two candidates for the correct colour, so if you choose between them randomly you

And what is wrong with someone figuring out for themselves and explaining to others why some suggestion makes sense logically, rather than just quoting the manual?
