Some distros use a biarch approach such where 32bit libs go into one folder and 64bit libs go into another folder (i.e. /usr/libs and /usr/libs64)

Other distros, namely Debian, use the Pure64 approach where only 64bit libraries go in /usr/libs. There is no mixing of 32bit libraries at all as you are expected to install a 32bit chroot to ruin 32-bit applications with 32bit libraries.

Some people find this approach to be "clean" as there is no mixing of 32bit and 64bit libraries. Other people find that creating a 32bit chroot is annoying.

Debian is working towards multiarch once Etch is completed that will apparently combine the benefits of both systems. I also read recently that people have now compiled a 64bit version of OpenOffice 2.0.3 (not for any speed advantages but just so it runs natively in a Pure64 environment without a 32bit chroot).

I'd go PowerPC before IA-64, or amd64, or whatever the hell you wanna call it. In the world of cross-platform software, there is no need for backwards-compatible hardware.

Not at source code is 64bit clean nor does it necessarily compile on other platforms. I see your point as being "In an ideal world..." but that isn't always the case.

    • Euro-Office must default to ODF to be considered "genuinely European", LibreOffice argues

      By David Uzondu · Posted

      Euro-Office must default to ODF to be considered "genuinely European", LibreOffice argues by David Uzondu Euro-Office is a web-based collaborative office suite that positions itself as a "European sovereign alternative" to American tech companies, backed by a coalition of developers including Nextcloud, IONOS, Abilian, BTactic, OpenProject, and, more recently, Tuta. The project officially went live a couple of days ago, but not before drawing heavy fire from LibreOffice developers, who called the marketing claim that Euro-Office represents the "first open-source office suite developed in Europe" a deceptive historical inaccuracy because projects like OpenOffice and LibreOffice existed decades earlier. Now that the project has launched, LibreOffice is back with another complaint, arguing that Euro-Office cannot consider itself "genuinely European" while it pushes proprietary Microsoft defaults on users. Euro-Office had promised to improve the OpenDocument Format (ODF) back in April, but the current release still plagues users with several technical failures. For instance, the suite lacks an admin setting to enforce ODF, and mobile editors completely block ODF saves, forcing files into Microsoft's OOXML formats. Some configurations force files into read-only mode, while editing frequently corrupts document formatting or erases data. LibreOffice thinks that merely supporting a format as an afterthought does not make you a sovereign alternative, as file formats are the battleground where" digital sovereignty is won or lost." The road to the first stable release of Euro-Office has been quite bumpy due to an aggressive public fallout with OnlyOffice, from which the coalition originally forked the project. OnlyOffice struck back by accusing the coalition of violating copyright terms under its AGPLv3 branding requirements by stripping the original branding anyway and forking the code. Getting Euro-Office up and running is a bit wonky (at least for non-technical users), as there is no direct installer to grab off the web. The easiest way we learnt is by using Docker. First, pull the official Euro-Office image from the GitHub Container Registry: docker pull ghcr.io/euro-office/documentserver:latest Then, run the container with active ports and a secure JWT token, enabling the test environment: docker run -i -t -d -p 8080:80 --restart=always -e EXAMPLE_ENABLED=true -e JWT_SECRET=my_secure_jwt_secret ghcr.io/euro-office/documentserver:latest And finally, open a web browser and go to the following address: http://localhost:8080 If you are running this on a remote server, replace localhost with your server's IP address. You will see the Euro-Office test page, where you can create new text documents, spreadsheets, or presentations directly in the browser. Image via Euro-Office Nextcloud promises that proper standalone desktop versions and mobile apps will arrive in a future release.
