python vs julia

Expericence with julia (coming from python)

python julia comment
print(1, 2) 🤦‍♂️ println(1, " ", 2) why I need to type ln?
slicing 👍 a[::2] 🤦‍♂️ a[1:2:end] too verbose (start/stop must be given)
🤦‍♂️ sin.(a) .- 1 silly dot
func def 👍 f(x) = 2*x
complex numbers 👍 1j 1im
👍 2x 🤦‍♂️ 0x syntax: invalid numeric constant "0x"

Sent files from command line to csv_plotter
#! /usr/bin/env python3
# Javascript only allows to fetch files from the local system by drag&drop.
# Here a local server is setup to sent a file from command line to csv_plotter.
# Furthermore, we also need to allow CORS...
# The server closes finally; thus the browser cannot reload the url/file.
# Example
# ./csv_sent <filename>

caret behaviour in contenteditable
<!DOCTYPE html>
<html>
<style>
div {background-color: #dfd}
span {background-color: #fbb}
</style>
<body>
The checking the caret behaviour in <code>contenteditable</code>. The caret is placed with an offset of 1 and then moved backwards. It is checked whether the caret is still in the current sibling (return value 0) or has entered the previous sibling (return value 5).
