Open Source Software Vs Free Software

Free software foundation was first introduced in 1985 by GNU founder Richard Stallman. Stallman believed that software beyond the monetary sense should be free to run, share, and modify.

Open source software movement came about by a gentlemen named Eric Raymond. Raymond believed that the free software movement needed to appeal to more commercial entities. Thus, Raymond founded the OSI - Open Source Initiative which introduced and encouraged the option of sharing software and modifying through the use of licenses. This ended up creating a platform in the marketplace for free software with a twist in comparison to the free software movement where true enthusiast of the movement believed it should be open and free without any restrictions to the end user.

Although the free software and open source m

Расширение Remote SSH для VSCode позволяет работать с файлами удаленной машины через ssh. В Windows 10 столкнулся с проблемой - если в параметрах ssh соединения используется директива ProxyJump, то Remote SSH не работает (не соединяется). Решил проблему тем, что обновил ssh https://chocolatey.org/packages/openssh до версии Win32 OpenSSH (Universal Installer) 8.1.0-beta.

Использую Docker Desktop на WIN10. Далее все команды выполняются из debian на WSL. При запуске docker run -ti -v $PWD/data:/var/lib/postgresql/data postgres получал ошибку, что у var/lib/postgresql/data неправильный owner. Однако docker run -ti -v $HOME/data:/var/lib/postgresql/data postgres работает исправно. Но папки $HOME/data просто нет! Нет ни у одного пользователя внутри WSL /home, ни внутри %userprofile% в win10. Загадка!

Остановил Docker Desktop, поставил https://docs.docker.com/engine/install/debian/. В результате:

How to use html tags in markdown with remark-parse?

From documentation: Note that toHast.allowDangerousHTML does not work: it’s not possible to inject raw HTML with this plugin (as it’s mean to prevent having to use dangerouslySetInnerHTML).

But still there is a way to allow html tags. Thanks to ChristianMurphy suggestion.

I've made just couple improvements:

1. Module rehype-dom-parse leads to error: 'document is not defined'. So I replace it with 'rehype-parse'.
2. Extract rehypeParser from handler, so it's created only once.
3. Also notice about sanitize: false
