Cutting Image Background with ImageMagick

Here is a small sequence of commands to cut the image of background (given that background is a solid color):

ORIG_IMAGE_NAME=green.jpg;
NEW_IMAGE_NAME=green-trans.png;
TMP_COLOR=`convert $ORIG_IMAGE_NAME -crop 1x1+0+0 txt:- | sed -n 's/.*\(#\S\+\).*/\1/p'`;
convert $ORIG_IMAGE_NAME -bordercolor $TMP_COLOR -border 1x1 -alpha set -channel RGBA -fuzz 30% -fill none -floodfill +0+0 $TMP_COLOR -shave 1x1 $NEW_IMAGE_NAME

Just change the first to vars. You can also adjust the fuzz percentage if needed.

DNS wildcard observations

Had an interesting case with DNS wildcard records: if you have a wildcard (*) A record – it works pretty fine, but if you specify a CNAME record to point to non-existing A record (which would normally be satisfied by wildcard A record) it won’t work, at least in the case I had. So as an example if you have:

Zone file for domain1
* IN A 111.111.111.111

Zone file for domain2:
host1 IN CNAME host1.domain1.

Then any query for host1.domain1 will resolve with no problems, but when you will try to resolve the host1.domain2 – it will fail. For this case you need to explicitly specify the host1.domain1. as follows:

Zone file for domain1
host1 IN A 111.111.111.111
* IN A 111.111.111.111

Interesting case, just to remember for the next time…

GNOME3 Delete button in Nautilus

Just noticed that Delete button in Nautilus of GNOME3 does not delete a file. Either Shift+Delete should be used to delete file completely or Ctrl+Delete for normal removal to Trash.

If you use Nautilus a lot and would like to get normal (old-style) behaviour, check out these post: http://www.khattam.info/howto-enable-delete-key-in-nautilus-3-fedora-15-2011-06-01.html

Basically you need to enable accels key editing in Gnome with gsettings (or gconf-editor), then reassign a button you wish and then disable change of accels key back (unless you want to have it permanently on, which I don’t advice, otherwise you might mess a bit by accident),

 

 

 

 

 

September, vacations…

It’s been a long while since I’ve been on such good vacations. More than one week away from office traveling around Cyprus and having all sorts of fun. Just a short post with list of things done during these nice days:

19/09/2011 – 20/09/2011:

  • Took car back from the garage, successfully fixed

21/09/2011:

  • Trip to Omodos village in the mountains (photos)

  • Short stop uphill from Limassol to enjoy nice view on a city (photos)

24/09/2011:

  • Trip to Akamas ending at the nice tavern in Latsi. Promised this trip to Yana for ages and finally did it. Like it a lot myself (photos)

25/09/2011:

  • Morning trip to Agia Napa with mam to let her enjoy the sea and the Sun. Ended with t-storm.
  • Nice food and movies on a sofa at home to finalize the vacations

There are also few random pics while Olga and Anatoly were in Limassol which I didn’t manage to put in different sets, so I created a separate one for them here.

I might miss some events in the above just because there were too many and I might forget something.

Finally, just wanted to mention that one week prior to vacations I had another guests coming to Agia Napa whom I managed to visit: Alexandra Negina and her sister. By some strange chance I had two of my classmates (Olga and Alexandra) visited me in one month, though I haven’t seen any of my classmates for years.
