Variety wallpaper changer on Ubuntu 14.04

After upgrading to Ubuntu 14.04, I noticed that Variety, the desktop wallpaper changer I'm using, stopped updating the desktop wallpaper (xfce here), although it continued to change the photos (by updating the application's indicator icon).

So, I started looking into the details and I found that I had to change two lines in ~/.config/variety/scripts/set_wallpaper script.

xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s "" 2> /dev/null
xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s "$WP" 2> /dev/null

xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitorLVDS/workspace0/last-image -s "" 2> /dev/null
xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitorLVDS/workspace0/last-image -s "$WP" 2> /dev/null


Duplicity fails on 3GB /tmp

Backup application Duplicity has just filled up my /tmp, located on / partition with 3GB free space, during verification of a full backup and, finally, reported 'failure'!
After quitting Duplicity, I have 1GB less free space on my / partition.

I wonder how much bigger the /tmp space need to be...


Update [2013/11/19]:

I've found the 'lost' GB into ~/.cache/deja-dup directory [naturally] (or /root/.cache/deja-dup if it runs under gksudo), but I still don't know why 3 GB of temporary space are not enough.


Yet another list of RSS feed readers

So, Google Reader is closing down its services tomorrow and the vast majority of its users have already chosen their next reader for their RSS feeds, since many bloggers and news sites have written about the alternatives.
Although I have chosen Tiny Tiny RSS for some weeks now and I'm using a local installation of it, I tried (and continue trying) also a number of cloud-based alternative services, listed below for possible future reference:
To be fair, for some RSS feeds I need to archive in email, I also run locally rss2email.

Update: I've just found this list with more than 60 alternatives, if anyone is interested.


"Hidden" gems of VLC

Today I found out the power of the "Devices" items in the VLC application.
With that I mean the option to record:
  • a videocast with the computer's camera [Video capture]
    Video effects, although can be seen on screen, are not recorded.
  • the usage of some application through its window (or the whole desktop, if you like) [Screen capture]
Audio capture didn't worked for me; maybe it's a configuration thing or a conflict, since video recordings had also no audio at all.

"Bad request Error 400" for GMail on Firefox

For the last 2-3 days I had an unusual situation to deal with. Whenever I tried to visit my GMail account using Firefox, the response was:
Bad request
Error 400
 At first I checked with the other browsers (Chrome, Opera and Midori) I have installed on my system. All connected without reporting anything.
Then, my next guess was misbehaving addons, but as I tweeted:
Since that approach didn't helped either, I decided to remove the GMail-related cookies. I used the "Remove cookie(s) for Site" addon and it deleted 78 cookies I had for GMail.

Unfortunately, I don't know which cookie was the "bad" one, but after deleting them I was again able to reconnect without problem.
