Git tips The key to solve conflicts: see the two conflicting diffs Updated 2025-07-16
The key to solve conflicts is:
You have to understand what are the two commits that touched a given line (one from master, one from features), and then combine them somehow.
Glitch Updated 2025-07-16
A glitch is more precisely a software bug that is hard to reproduce. But it has also been used to mean a software bug that is not very serious.
Ciro Santilli's hardware Bicycle locks Updated 2025-07-16
December 2023: found the keys for the Kryptonite Kryptolock and the Abus in the house, so now I've got backup!
2023 lost one of the two keys to Kryptonite Kryptolock and to the Abus padlock:
- rebuying cryptonite, seems exactly the same. If the old key is ever found, it can re-enter usage.
- replacing Abus padlock buying a similarly featured Master lock "commercial" padlock, looks like this one: www.screwfix.com/p/master-lock-excell-laminated-steel-master-keyed-weatherproof-padlock-51mm/153KH
2018 Kryptonite Kryptolock. Looks like: www.kryptonitelock.com/en/products/product-information/current-key/002031.html Includes Transit Flexframe-U Bracket carrier

Globalization reduces the power of governments Updated 2025-07-16
While Ciro Santilli is a big fan of having "one global country" (and language), which is somewhat approximated by globalization, he has come to believe that there is one serious downside to globalization as it stands in 2020: it allows companies to pressure governments to reduce taxes, and thus reduces the power of government, which in turn increases social inequality. This idea is very well highlighted in Can't get you out of my head by Adam Curtis (2021).
The only solution seems to be for governments to get together, and make deals to have fair taxation across each other. Which might never happen.
GNU Compiler Collection Updated 2025-07-16
GNU parallel Updated 2025-07-16
This program makes you respect GNU make a bit more. Good old make with
-j can not only parallelize, but also take in account a dependency graph.Some examples under:
man parallel_exampesTo get the input argument explicitly job number use the magic string sample output:
{}, e.g.:printf 'a\nb\nc\n' | parallel echo '{}'a
b
cTo get the job number use sample output:
{#} as in:printf 'a\nb\nc\n' | parallel echo '{} {#}'a 1
b 2
c 3
c 3{%} contains which thread the job running in, e.g. if we limit it to 2 threads with -j2:printf 'a\nb\nc\nd\n' | parallel -j2 echo '{} {#} {%}'a 1 1
b 2 1
c 3 2
d 4 1% symbol in many programming languages such as C.To pass multiple CLI arguments per command you can use sample output:
-X e.g.:printf 'a\nb\nc\nd\n' | parallel -j2 -X echo '{} {#} {%}'a b 1 1
c d 2 2 Balance of power Updated 2025-07-16
Bare metal Updated 2025-07-16
Or in other words, it is basically implementing an operating system/firmware yourself ad hoc, together with your actual program.
Baryon vs meson vs lepton Updated 2025-07-16
"Barys" means "heavy" in Greek, because protons and neutrons was what made most of the mass of known ordinary matter, as opposed notably to electrons.
Baryons can be contrasted with:
- mesons, which have an even number of elementary particles. The name meson comes from "medium" since their most common examples have two quarks rather than three as the most common baryons such as protons. So they have less mass than a proton, but more than an electron, this medium mass.
- leptons, which are much lighter particles such as the electron. "Leptos" means "fine, small, thin".

gnuplot Updated 2025-07-16
Tends to be Ciro Santilli's first attempt for quick and dirty graphing: github.com/cirosantilli/gnuplot-cheat.
When it doesn't, you Google for an hours, and then you give up in frustration, and fall back to Matplotlib.
Couldn't handle exploration of large datasets though: Survey of open source interactive plotting software with a 10 million point scatter plot benchmark by Ciro Santilli
