Just because I like GNU parallel: parallel -kj1 'f="{}"; [[ -f "${f/data/A}" ]] || echo $f' ::: *_data.csv

This is better relative to the `sed` solution as it handles the `0000` case well.

I didn't realize Zsh (and Bash) was capable of removing zero padding in that way. Everybody has there own style, but I would prefer to print the missing file pattern and avoid loops. If you have GNU parallel installed (works in bash)

Just for fun some bash: for k in $(seq -f %04.f 1 501); do f="${k}_A.csv" ! [[ -f "$f" ]] && echo $f || : done or more succinctly, for k in {0001..0501}_A.csv; do ! [[

Gold had intrinsic value before electronics, but for basically the same reason: it's immutable. The bitcoin blockchain is also immutable.

Github flavored markdown does do tables (in a manner that's almost equivalent to org): https://github.com/adam-p/markdown-here/wiki/Markdown-Cheats...

Your algorithm had a bit of a typo--you want to subtract (resp. add) to calculate the odd and even parts of a function. If you don't have a nearly symmetric span of x values, you may need to do extrapolation to obtain one, which may be

This can be rather difficult for general data where an explicit equation isn't obvious (even though it'll work quite often as pointed out by johncolanduoni below). [I think it's neat that] for sufficiently smooth and periodic

Two fluids with a density difference and a velocity gradient usually have a common force acting upon them, e.g. gravity, which enforces so-said interface. Perturbations to the average interface are restored via this force, and these perturb

Gravity is the result of an appropriately accelerating frame (i.e. the curvature of spacetime).

Name seems fine to me. From the first paragraph of the wiki-page: In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two media when the force of gravity or buoyancy tries to restore equilibriu

They claim that it has an unlimited number of write cycles.

Don't know why this is being downvoted. It's important for scientists to use the correct, well-established terms when discussing their research. This is most true for formal publications. Velocity is a vector quantity--it describe

They use the term velocity to mean speed a lot :(.

No, but I am very thankful for your posted workaround.
