Git - git-worktree Documentation
https://git-scm.com/docs/git-worktree, posted Jun '22 by peter in development documentation howto reference versioncontrol
In its simplest form,
git worktree add <path>automatically creates a new branch whose name is the final component of
<path>, which is convenient if you plan to work on a new topic. For instance,
git worktree add ../hotfixcreates new branch
hotfixand checks it out at path
../hotfix. To instead work on an existing branch in a new worktree, use
git worktree add <path> <branch>. On the other hand, if you just plan to make some experimental changes or do testing without disturbing existing development, it is often convenient to create a throwaway worktree not associated with any branch. For instance,
git worktree add -d <path>creates a new worktree with a detached
HEADat the same commit as the current branch.
If a working tree is deleted without using
git worktree remove, then its associated administrative files, which reside in the repository (see "DETAILS" below), will eventually be removed automatically (see
gc.worktreePruneExpirein git-config), or you can run
git worktree prunein the main or any linked worktree to clean up any stale administrative files.
Damn Cool Algorithms: Levenshtein Automata
blog.notdot.net/2010/07/Damn-Cool-Algorithms-Levenshtein-Automata, posted Mar '22 by peter in development nlp reference text toread
The basic insight behind Levenshtein automata is that it's possible to construct a Finite state automaton that recognizes exactly the set of strings within a given Levenshtein distance of a target word. We can then feed in any word, and the automaton will accept or reject it based on whether the Levenshtein distance to the target word is at most the distance specified when we constructed the automaton. Further, due to the nature of FSAs, it will do so in O(n) time with the length of the string being tested. Compare this to the standard Dynamic Programming Levenshtein algorithm, which takes O(mn) time, where m and n are the lengths of the two input words! It's thus immediately apparrent that Levenshtein automaton provide, at a minimum, a faster way for us to check many words against a single target word and maximum distance - not a bad improvement to start with!
Of course, if that were the only benefit of Levenshtein automata, this would be a short article. There's much more to come, but first let's see what a Levenshtein automaton looks like, and how we can build one.

I was under a common engineer misapprehension that BFE [Big Freaking Enterprise] sales requires playing golf, inviting clients to steak dinners, and having budgets beyond to reach of small businesses. This is not 100% true: you can hack the BFE procurement process to your advantage. Let's dig into how.

The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with SemVer, by describing the features, fixes, and breaking changes made in commit messages.

Spreadsheet Formulas for Personal Finance

I love spreadsheets. Spreadsheet programs like Microsoft's Excel, Apple's Numbers and Google Sheets are the secret heroes of our civilization.
I've also been interested in personal finance and the FIRE community for a while—not so much in the early retirement aspect but in the financial literacy it teaches its members. I have combined my passion for both into one mega-spreadsheet that I use to track my income, expenses, savings and investments in one overview. While creating this spreadsheet I got proficient in some new formulas, which I'll share here—and also write down for my own reference.

So you're all done recording your next song. You've laid down final takes for all the tracks, mixed everything and decided on the final master. Congrats!
But before you call it a day and prepare to distribute to streaming platforms, there are a few things many musicians forget to do that can take their song to the next level.

We make very careful considerations about the interface and operation of the GNU coreutils, but unfortunately due to backwards compatibility reasons, some behaviours or defaults of these utilities can be confusing.
This information will continue to be updated and overlaps somewhat with the coreutils FAQ, with this list focusing on less frequent potential issues.
