On the way to Trixie, polkitd (Policy Kit Daemon) has lost the functionality to evaluate its .pkla (Polkit Local Authority) files.

$ zcat /usr/share/doc/polkitd/NEWS.Debian.gz 
policykit-1 (121+compat0.1-2) experimental; urgency=medium

  This version of polkit changes the syntax used for local policy rules:
  it is now the same JavaScript-based format used by the upstream polkit
  project and by other Linux distributions.

  System administrators can override the default security policy by
  installing local policy overrides into /etc/polkit-1/rules.d/*.rules,
  which can either make the policy more restrictive or more
  permissive. Some sample policy rules can be found in the
  /usr/share/doc/polkitd/examples directory. Please see polkit(8) for
  more details.

  Some Debian packages include security policy overrides, typically to
  allow members of the sudo group to carry out limited administrative
  actions without re-authenticating. These packages should install their
  rules as /usr/share/polkit-1/rules.d/*.rules. Typical examples can be
  found in packages like flatpak, network-manager and systemd.

  Older Debian releases used the "local authority" rules format from
  upstream version 0.105 (.pkla files with an .desktop-like syntax,
  installed into subdirectories of /etc/polkit-1/localauthority
  or /var/lib/polkit-1/localauthority). The polkitd-pkla package
  provides compatibility with these files: if it is installed, they
  will be processed at a higher priority than most .rules files. If the
  polkitd-pkla package is removed, .pkla files will no longer be used.

This applies now to the polkitd version 126-2 destined for Trixie.

The most prominent issue is that you will get an error message: "Authentication is required to create a color profile" asking for the root(!) password every time you remotely log into a Debian Trixie system via RDP, x2go or the like.

This used to be mendable with a .pkla file dropped into /etc/polkit-1/localauthority/50-local.d/ ... but these .pkla files are void now and need to be replace with a Javascript "rules" file.

The background to his is quite a fascinating read ... 13 years later:
https://davidz25.blogspot.com/2012/06/authorization-rules-in-polkit.html

The solution has been listed in DevAnswers as other distros (Fedora, ArchLinux, OpenSuse) have been faster to depreciate the .pkla files and require .rules files. I amended the solution given there with checking for root to be automatically authenticated, too.

So, create a 50-color-manager.rules file in /etc/polkit-1/rules.d/:

and run systemctl restart polkit.

You should be good until polkit is rewritten in Rust.

I have been late to adopt an on-premise cloud solution as the security of Owncloud a few years ago wasn't so stellar (cf. my comment from 2013 in Encryption files ... for synchronization across the Internet). But the follow-up product Nextcloud has matured quite nicely and we use it for collaboration both in the company and in FLOSS related work at multiple nonprofit organizations.

There is a very annoying "feature" in Nextcloud though that the designers think menu items for apps at the top need to be limited to eight or less to prevent information overload in the header. The whole item discussion is worth reading as it it an archetypical example of design prevalence vs. user choice.

And of course designers think they are right. That's a feature of the trade.
And because they know better there is no user configurable option to extend that 8 items to may be 12 or so which would prevent the annoying overflow menu we are seeing with 10 applications in use:

Luckily code can be changed and there are many comments floating around the Internet to change const minAppsDesktop = 8. In this case it is slightly complicated by the fact that the javascript code is distributed in compressed form (aka "minified") as core/js/dist/main.js and you probably don't want to build the whole beast locally to change one constant.

Basically

gets compressed during build time to become part of one 15,000+ character line. The relevant portion reads:

Well, we can still patch that, can we?

We've recently relocated to Beijing, China. A fellow expatriate invited me to Internations which is basically Xing with a focus on people living (or having lived) abroad. As I've used the Xing Greasemonkey script to enlarge user images on mouse over for years now, I missed that function on Internations immediately.

So I created a derivative of the Xing script which you can download here (2kB), v1.1.

You need to install the Greasemonkey Firefox Addon and then click on the above download link to get the script which will automatically be active on Internations.

If you care, my shiny new Internations profile can be found here.

Updates:

07.10.11 Updated to v1.1 to support Internations new NetDNA Content Distribution Network (in-cdn.net) URLs. Thanks to Marc for the prod via the comment below.

20.11.11 I've seen a new URL scheme in this image. URL ending in _e__x.jpg. If that's not an error but a new scheme, I'll update the script to support it.

06.07.18 I've deleted my Internations account as the site does not seem to have gained enough traction to still warrant keeping an account around. The (understandable) need by the team to increase monetization ("Albatros membership") doesn't work well with having not much more to offer than local meetups organized by volunteers.

The Livesearch (Javascript iterative search) plugin to Serendipity (s9y) currently does not work with the Bulletproof template active.

Matthias Mees (YellowLed) and Don(ald) Chambers are looking at it.
