A: Understanding the Matrix protocol vs Matrix server and what can be implemented from scratch Specification You understand correctly. [Matrix][] is an interface for federated encrypted communication. From the first page of the spec: > Matrix defines a set of open APIs for decentralised communication, suitable for securely publishing, persisting and subscribing to data over a global open...

Filter stashes by pathspec The documentation for `git stash list` says > ### [`list []`][doc] > List the stash entries that you currently have. Each stash entry is listed with its name (e.g. `stash@{0}` is the latest entry, `stash@{1}` is the one before, etc.), the name of the branch that was current when the entry was mad... (more) |

A: How to easily support time frame grouping in queries? In SQL Server 2022+, there's a dedicated binning function called `DATEBUCKET`. > Each of these statements increments `DATEBUCKET` with a bucket width of `1` from the origin time: > > ```sql > DECLARE @date DATETIME2 = '2020-04-30 21:21:21'; > SELECT 'Week', DATEBUCKET(WEEK, 1, @date) > UNION ...

A: What is a reasonable minimum for making a FOSS project inviting to contributors? Matthew's list is pretty good, although I don't think one has to do all the things on it as a "minimum." I offer one minimum and a couple nice-to-haves. Some of these I have learned as a contributor; some as a maintainer. Must 1. Don't be a jerk. When people engage with your project, don't be d...

A: GnuTLS config for my own root CA, for use on internal server Does GnuTLS support CA Name Constraints (RFC 5280, 4.2.1.10), so you can limit the valid domains directly in the root CA? I'm not aware of any CAs that self-limit this way,[^moz] except for when the US government tried (unsuccessfully?) to get one approved by the CA/B forum for `.gov` and `.mil`. ... (more) |

A: Should a salt be stored in the same database as the hash? With bcrypt, the salt is stored in the same string as the hash. This is done so that you have everything you need to get that hash identifier if you know the password.[^pepper] Wikipedia breaks down the format: > ## Description > The input to the bcrypt function is the password string (up to 72 b...

A: Git apply vs git am Each of them has an analog to another Git command. But instead of objects in the repository, these take text file(s) created either by you or someone else. `git apply` Think of this as Applying a `git stash` from a text file. Applies a delta to your worktree. It's nominally a Git-flavored ve... (more) |

A: Are "strong passwords" at all meaningful? Passwords are annoying. Nobody really enjoys passwords, which is why "The End of Passwords" articles keep circulating. I'm looking forward to the day the prediction comes true, but in the meantime passwords are the most common way to do authentication anywhere with a computer. I made a chart to cl... (more) |

A: How to display overlapped content in an e-mail I don't understand your "Venn Diagram" explanation. Are you wanting the image behind the text? If you mean wrapping around the image, you can do this: Instead of cells of a big table, put the image into its own table and `align="right"` the table. Then text will reflow around the table (even in yu... (more) |

A: Can GitHub rewrite authorship of commits? It doesn't change commit data when you push. You have to set your local email address to the `noreply` one. > ## About commit email addresses > […] > > If you'd like to keep your personal email address private, you can use a `noreply` email address from GitHub as your commit email addres...

Can GitHub rewrite authorship of commits? GitHub has a setting wherein they offer to "anonymize" your user email from, say, somebody@example.com to somebody@users.noreply.github.com. I presume this is to prevent you from getting spam from a scraper that reads the metadata on commits to public repositories. How do they do this without inva... (more) |

A: What are the benefits of starting a Git repo with an empty commit? This sounds to me like someone had a problem once and they've decided upon a somewhat silly way to keep that from ever happening again. The big repository hosts have a different way of addressing it. They (offer to) make you a README.md and a .gitignore for the first commit and you can stem everyt... (more) |

A: Command to format code from repo into single markdown file Sylvester's answer is great, but I wanted to point out that interpolation only happens in double-quoted strings (`"`), not in single-quoted ones (`'`). If you have lines that don't need any variable or command interpolation, you can single-quote and skip escapes: ```bash find . -name ".py" -pr... (more) |
