Git tips Linear history vs branching Updated 2025-07-16
Some people like merges, but they are ugly and stupid. Rebase instead and keep linear history.
Linear history:
5 master

1 first commitBranched history:
7 master

You may disconnect now if you still like branched history.

Limit (mathematics) Updated 2025-07-16
The reason why the epsilon delta definition is so venerated is that it fits directly into well known methods of the formalization of mathematics, making the notion completely precise.

Git tips Oh, but there are 2 trees: local and remote Updated 2025-07-16
Oh but there are usually 2 trees: local and remote.
So you also have to learn how to observe and modify and sync with the remote tree!
But basically:to update the remote tree. And then you can use it exactly like any other branch, except you prefix them with the remote (usually
git fetchorigin/*), e.g.:origin/masteris the latest fetch of the remote version ofmasterorigin/my-featureis the latest fetch of the remote version ofmy-feature

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.

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
