Ubuntu Forums post :

A long hiatus, nothing considering geological times :)

The so called summer season has started here. First day of vacation. I fresh installed Ubuntu 14.10 still in development, running great, and am testing out LXDE-Qt on top of lubuntu 14.04 which was not that of a good idea. Will probably have to fresh install over again and go for a pure LXQt environment. This laptop’s battery died last year, so it became a laptop on a leash for tests.

The Ubuntu Forums are keeping me busy, I’ve always liked forums, these ones in particular. Not sure why, I like the place, the Staff team, the way people can get helped, the way I can help and learn in the process. It is a great learning resource to me. One command I got reminded of a few days ago : apt-cache madison which shows packages versions available from the repositories, even if not in the sources.list. Complementary to apt-cache policy :)


Social Fixer for Facebook

I think I tried this long ago, but I have not been a real Facebook user, so I stopped using it.

Now that I manage a Facebook page for my students, I find myself a lot more on Facebook. I’ve been annoyed by all the post suggestions and game stuff and upcoming events and such that show up _a lot_ on my news feed. I do understand the economical model that makes Facebook at no charge for me and turns me into a merchandize. Nonetheless, it bugs me, hurts my eyes and tickles my nerves. I choose to watch (mostly and when possible) add free TV programs, do not listen at all to commercial radios and try to walk away from commercial adds that pollute my brain as much as I can.

I have to say I’m much impressed with them now, and their support. Social Fixer changes the way “you” see Facebook in your browser (too bad there is no SF for the FB mobile app for now), is customizable so you can hide things, move them to a tab and more to make FB  experience much better imho.

When I’ve needed help, they answered within a minute, wow, have been friendly and everything. Their support group on FB is quite active and full of information. Volunteer work I warmly recommend.

moodle 1.9 : hide course total in gradebook

This is not possible in moodle 1.9 without modifying the code, hiding total course grade hides individual grades too. Here is a workaround :

  • In gradebook, turn on editing and go to each student total (can be tedious if having a large number of students enrolled in the course)
  • Hide each student total

First screenshot is a student view before hiding, last one is after. Voilà :)


How to fix it in the code :

moodle 2. : different assignments for different groups

We stumbled on this issue, with a stock moodle install there was no way to assign different activities to separate groups.. What a headache. The fix is here :

I guess it is not a bug :)

Ubuntuforums : changes on accounts permissions.

For a very long time, we did not want to take away from new users the possibility to customize their profiles. Fact is several of us in the forums Staff team had to spend at least one hour a day cleaning after spammers. Spammers tactic: fill profile fields with spam links, upload spam pics as avatar, even create user albums with the pics, comment on other regular users profiles, send PMs or emails etc. All of these are sneaky as we need to examine each profile to find them out.

Starting today, users with post counts < 50 will not be able anymore to customize their profile. It’s been a difficult decision we agonized over a for a long time. We believe 50 posts is a good comprise between annoying spammers and annoying genuine users. Oh well.
