csvgrep from csvkit Updated 2025-07-16

Simple example:

printf '00,11,22\n33,44,55\n' | csvgrep -H -c2 -r '^11$' | tail -n+2

output:

00,11,22

csvkit Updated 2025-07-16

Lots of features, but slow because written in Python. A faster version may be csvtools. Also some annoyances like obtuse header handing and missing features like grep + cut in one go: csvgrep and select column in csvkit.

csvtools Updated 2025-07-16

github.com/maroofi/csvtool

A fast version of a somewhat subset of csvkit, written in C.

Build failed with undefined reference to pcre_config on Ubuntu 23.04: github.com/DavyLandman/csvtools/issues/18

Unfortunately it is lacking some basic options, like optional header + selecting column by index on csvgrep (though csvcut has it). The project seems kind of dead.

Also unclear if it allows to filter + print only selected columns.

A research centre examining the implementation of alternatives to meat, backed by £38m, will be launched by the University of Leeds.
The virtual research centre will look into lab-grown meat as well as plant and fungus-based meat alternatives to determine the health, sustainability and feasibility of moving away from traditional meat.

Mostly on vintage electronics. Lots of focus on microwave, which he has worked a lot with.

Has been going wild with restoration and reverse engineering of the Apollo moon mission.

Braindumping Updated 2025-07-16

There are two ways:

manually dumping your brain on media such as notebooks, wikis or videos, i.e. forming a personal knowledge base
technically using sensors for brain scanning

Yitang Zhang's theorem Updated 2025-07-16

There are infinitely many primes with a neighbor not further apart than 70 million. This was the first such finite bound to be proven, and therefore a major breakthrough.

This implies that for at least one value (or more) below 70 million there are infinitely many repetitions, but we don't know which e.g. we could have infinitely many:

k, k + 2

(1)

or infinitely many:

k, k + 4

(2)

or infinitely many:

k, k + 6, 999, 999

(3)

or infinitely many:

k, k + 2 an d k, k + 4

(4)

but we don't know which of those.

The Prime k-tuple conjecture conjectures that it is all of them.

Also, if 70 million could be reduced down to 2, we would have a proof of the Twin prime conjecture, but this method would only work for (k, k + 2).

The accuracy is crap for anything but people. But still. Well done. Tested on Ubuntu 22.10, P51.

The 10 Tesla magnet was made at GE Schenectady and they sold magnets to research facilities world wide before the team formed Intermagnetics General.
