After 5 months with GNOME 3.0, I'm really happy with the experience. At the end of work day,
my mind is no more exhausted of windows placement fighting and application finding.
GNOME 3.0 is really stable, except with the Open Source driver on my Radeon 5870 (4 crashes in 2 months).
I really like the behavior of dual-head where the secondary screen has only one virtual screen.
For me, there are just 3 annoying points:
- Ctrl + Del to remove a file in Nautilus, may be it's a Fedora settings but this change is just @!# I've already a Trash to undo my mistakes (http://www.khattam.info/howto-enable-delete-key-in-nautilus-3-fedora-15-2011-06-01.html)
- Alt key to shutdown, no I don't want to waste energy for days and my PC boots quickly.
- only vertical virtual screens, I found a bit painful to move down two screens when the screen is reachable with one move with a 2x2 layout but I understand this layout doesn't fit well with the GNOME 3 design.
To have a good experience with GNOME 3, I use:
- Windows key + type to launch everything
- Ctrl + Shift + Alt + arrows to move the application between the virtual screen
- Ctrl + click in the launcher when I really want a new instance (the default behavior is perfect)
- snap à la Windows 7 is great
- Alt + Tab then the arrow keys to select an app
Don't forget to read https://live.gnome.org/GnomeShell/CheatSheet or the Help (System key + 'Help').
It's not specific to GNOME 3 but you can change the volume when your mouse is over the applet (don't click, think hover) and a mouse scroll.
With GTK+, do you know you can reach the end of scrolled area with a left click on the arrow and a specific position by middle click?
I'm impressed by the new features of GNOME 3.2 and I'm waiting for Fedora 17 to enjoy it!
The day I discovered that Firefox does not behave like Chrome/IE on Ajax redirects, Firefox 7.0 is out with the fix!
PS: a simple request.is_ajax () after a redirect() in Django highlights the problem.
I'm impressed by the activity of the coreutils project (unix commands such as ls, df, etc). At first glance, you might think command line tools are written for good and only few changes are applied to ensure compatibility with the platforms. With several releases a year and new features for each, it's really an active project indeed.
You want to show the local time for 9AM next Friday on the west coast of the US, it's possible:
$ date --date='TZ="America/Los_Angeles" 09:00 next Fri'
The maintainers/contributors (Pádraig Brady, Jim Meyering and Eric Blake) are nice and quick to commit your patches.
So don't be intimidated it's not the glibc project!
PS: I'm waiting for the tag on translationproject.org to be able to push the latest French translation.
If you expect 'Alt + d' wil only remove the first part 'foo_' of 'foo_bar' with the great python-mode, you can make this change to python-mode.el:
- (modify-syntax-entry ?\_ "w" py-mode-syntax-table)
+ (modify-syntax-entry ?\_ "_" py-mode-syntax-table)
Thank you Ivan.
Update with python-mode v6.0.4, add this line to python-mode-syntax-table (line 153):
(modify-syntax-entry ?\_ "_" table)
