Apache alias to map www.domainname.tld to just domainname.tld
To have, say www.visionier.nl automatically map to visionier.nl:
- Create a DNS CNAME that creates this map.
- Add a
ServerAlias www.domain name.tld
to the<VirtualHost IP-address:80>
, e.g.ServerAlias www.visionier.nl
added to<VirtualHost 80.84.230.245:80>
will do the trick.
rsync
Always run rsync through ssh:
rsync -e 'ssh -l ssh_account' -vaz src_dir target_tld:dst_dir
xattr: set where from
Sometimes the ‘where from’ metadata contains an unreadable URL from some cache. Replace it with the most human readable version of the original. This way, you can always find out the source of the original document (image, movie, etc.).
xattr -w 'com.apple.metadata:kMDItemWhereFroms' source_url file_name
xattr: UTF-8 copy & paste
Mac OS X stores a special attribute: http://www.nabble.com/MacVim-file-encoding-and-Quicklook-td17289501.html
To create an UTF-8 file using vi(1) and open it correctly as UTF-8 file in TextEdit (as opposed to Open As… UTF-8):
- vi file
- xattr -w com.apple.TextEncoding 'UTF-8;134217984' file
- open file

HP scanjet 4670
Nice vertical flatbed scanner but shitty crappy software. Come on HP, you can do better! After upgrade to Mac OS X 10.5.8 scanner did not work anymore.
- First, follow instructions on hp scanjet 4670 and OS X 10.4.8 -- YIKES! » I Did Get It Going....
- Next, follow instructions on Scanjet 4670 driver for Mac OS Leopard 10.5? » Kenneth Koller's comment.
- Download COL10842b.dmg
- Double-click COL10842b.dmg to mount.
- Once the window opens with the installers...control click it...and select see package contents.
- Navigate to contents/macos/subinstallers.
- Double-click on the hp scanjet 4600.
- Go to top directory of SJ4600 (mount point *.dmg) and double-click HP ScanJet Software Installer to install all components (not sure if this is still necessary).
- Enjoy
I will never buy any HP products anymore.
