Why do we need training?

I'm the original creator of Ghostty. It's been a few years now! I don't know why this is on the front page of HN again but let me give some meaningful updates across the board.

First, libghostty is _way more exciting_ nowadays. It is already backing more than a dozen terminal projects that are free and commercial: https://github.com/Uzaaft/awesome-libghostty I think this is the real future of Ghostty and I've said this since my first public talk on Ghostty in 2023: the real goal is a diverse ecosystem of terminal emulators that aim to solve specific terminal usage but all based on a shared, stable, feature-rich, high performant core. It's happening! More details what libghostty is here: https://mitchellh.com/writing/libghostty-is-coming

I suspect by the middle of 2027, the number of people using Ghostty via libghostty will dwarf the number of users that actually use the Ghostty GUI. This is a win on all sides, because more libghostty usage leads to more stable Ghostty GUI too (since Ghostty itself is... of course... a libghostty consumer). We've already had many bugs fixed sourced by libghostty embedders.

On the GUI front Ghostty the apps are still getting lots of new features and are highly used. Ghostty the macOS app gets around one million downloads per week (I have no data on Linux because I don't produce builds). I'm sure a lot of that is automated but it's still a big number. I have no telemetry in Ghostty to give more detailed notes. I have some data from big 3rd party TUI apps with telemetry that show Ghostty as their biggest user base but that is skewed towards people consuming newer TUIs tend to use newer terminals. The point is: lots of people use it, its proven in the real world, and we're continuing to improve it big time.

Ghostty 1.3 is around the corner, literally a week or two away, and will bring some critically important features like search (cmd+f), scrollbars, and dozens more. In addition to GUI features it ships some big improvements to VT functionality, as always.

Organizationally, Ghostty is now backed by a non-profit organization: https://mitchellh.com/writing/ghostty-non-profit And just this past week we signed our first 4 contributor contracts to pay contributors real money! Our finances are all completely public and transparent online. This is to show the commitment I have to making Ghostty non-commercial and non-reliant on me (the second part over time).

That's a 10,000 foot overview of what's going on. Exciting times in Ghostty land. :) Happy to answer any big questions.

Are you talking about the cipher tests that are run when any cipher library is loaded?

There's a reason they do that and it's not for shits and giggles. You could find yourself with broken ciphers and not know it.

Skipping the cipher (or hash - not sure now) tests seem like a good way to get exploited.

Is there a source for this? My Google- and GitHub-fu turns up nothing.

Why not use both DLLs? Prefer win32 wherever possible and use the lower level APIs only if absolutely necessary. Benchmark after you have figured this out. Performance is probably not a thing at this level of abstraction.
