comment Tool for automating video splicing at slide transitions?
I don't want to manually figure out where the transitions are. Can kdenlive analyze the video and automatically suggest timestamps which might be good transitions? They're pretty clear transitions (e.g. a video of a slide show, the only big changes being between one slide and the next, though some of the time someone is writing on the slides you see the writing, but not the person)

comment Video editing software options?
Much easier interface than Openshot: visible audio waveform, video thumbnails on the timeline, good keyboard shortcuts, copy-paste from timestamp, which is more precise, not a cpu hog.

comment How do I detect and remove Python packages installed via pip?
@oli pip freeze, in precise at least, also lists packages installed by apt, as other answers here describe.

comment Is there a command-line program to read tags from .m4a files?
Thanks! Is there an Ubuntu or Debian package, or something that pip or easy_install can handle?

comment What to use to quickly cut Audio/Video
Thanks! avconv is blazingly fast and clear and convenient for splitting out clips if you know what start/stop times you want. No need to figure out which OpenShot video format your source file corresponds to, which I still don't know for sure....

comment What to use to quickly cut Audio/Video
Thanks! But these ppa versions are out-of-date. Are the versions in Precise 12.04 good? Or can someone suggest better ones?

comment How to find out which backported packages are available, and avoid losing packages when manually upgrading?
Thanks for your patience. OK, I agree that given the unambiguous meaning of the commands given, that's what apt has to do. So I guess I'm looking for a different command that would "do the right thing" for this sort of common case and make it easier to upgrade, e.g., all the binary packages that come from a given backported source package and are currently installed or are new and required. Perhaps it could just look for anything it is removing and see if that exists in the repository specified by -t. I'm basically trying to get closer to the ease of upgrades when backports aren't pinned low.

comment How to find out which backported packages are available, and avoid losing packages when manually upgrading?
Cool - I was hoping that -t would work that way also. But what if it was just "sudo apt-get -t precise-backports install ipython" - might that also be smart enough to properly upgrade ipython-notebook and ipython-qtconsole also?

comment How to find out which backported packages are available, and avoid losing packages when manually upgrading?
Sure, ipython-notebook says "Depends: ipython". So if I have ipython-notebook 0.12.1 installed, as well as ipython 0.12.1 (both from the same source package to boot), and 0.13.1 is in backports, and I upgrade ipython, why would it choose to remove ipython-notebook rather than upgrade it (and install Depends: ipython-notebook-common, a new dependency package in that version)

comment How to find out which backported packages are available, and avoid losing packages when manually upgrading?
Very helpful. Thanks! But on the last question: as I noted, even available binary packages from the same source package, which are in backports, don't get upgraded and are removed instead, like ipython-notebook. When would that ever be a user's intent? Can that be fixed/avoided?

comment way to detect which workspace you are currently in from the command line
Thanks. I had to remove " --replace" from the compiz_running test, and also seemed to get the wrong value for vsize (1 vs 2) when running this on Precise 12.04, even though ccsm General Options said my Desktop Size / Vertical Virtual Size is 2.

comment Add event to google calendar from chrome/chromium via .ics file
Thanks, nicely written! But this is a single event, and I don't want to add yet another new calendar to get it. That would clutter up my list of calendars and complicate adding reminders. I just want to add a single event to my own personal google calendar, with the help of this .ics file. I've clarified the title of this question.

Thanks Paul, for lots of helpful analysis here! But I also agree with Flimm. Can you start off with a simple answer to the question as asked?

comment youtube-dl is not working
This is actually a bug, and I entered a launchpad bug *bugs.launchpad.net/ubuntu/+source/youtube-dl/+bug/1128610) that refers to the upstream fix.

comment Wireshark problem. Can't select default interface
This is unnecessarily dangerous and problematic, because there are far more exploitable bugs when running the full gui as root, and configuration issues can crop up when a gui program runs as root. See the dpkg-reconfigure solution at How do I run WireShark, with root-privileges? - Ask Ubuntu for a much better option

The answers here are more dangerous than the standard "sudo dpkg-reconfigure wireshark-common" approach, which is documented in this question: How do I run WireShark, with root-privileges? - Ask Ubuntu. This question is essentially a duplicate of that one.

comment No facility exists in Update Manager to upgrade to a new version, why?
Wow, this is surprisingly hard to find, particularly given that you actually have to quit the thing after telling it what you want. And especially on my netbook, where the "settings" button isn't visible because the update manager window is too large for the display. And there is no menu. I wonder what fraction of users are expected to ever upgrade from an LTS to another non-LTS version?
