When using Mac OS X, I used to use the CLI vim by the excellent Homebrew package manager.
Now I’ve just stumbled over macvim, which is kind of a “deluxe vim” for Mac OS X, including adjusted key bindings for the Mac and a GUI menu, supporting Cocoa file dialogs, among others.
It’s highly recommended if you want to have the best of both the CLI and GUI editor worlds.
If you ever need to quickly test an FTPS server, the CLI ftp client http://lftp.yar.ru is quite handy.
After upgrading Debian, OpenDKIM sometimes stops running or fails to properly restart. If you don’t actively monitor your ZCS server, the only way to detect this is either through a growing mail queue of unsent messages or through a note in the ZCS server admin panel.
Usually, manually restarting either OpenDKIM itself or the whole ZCS server once “fixes” the problem:
# service zimbra restart
or
# /etc/init.d/zimbra restart
In other cases, fixing the permissions may help:
# /opt/zimbra/libexec/zmfixperms -verbose -extended

Does dragging windows to the adjacent workspace in Mac OS X feel sluggish? Try lowering the according delay, e.g. to 0.1 seconds. For a persistent change, enter the following in a terminal:
defaults write com.apple.dock workspaces-edge-delay -float 0.1; killall Dock
If you’d like to have a longer delay, try setting a value of 1.0 or even 2.0.
Mac OS X comes with a pretty useful tool to list all the details about your system:
# system_profiler
E.g. to find out whether your RAM supports ECC:
# system_profiler|grep ECC ECC: Disabled
Or wether your SSD supports TRIM:
# system_profiler|grep TRIM TRIM Support: Yes
A friend recently told the following joke:
“The idea that git can be used offline is an illusion – you still need connectivity for googling which arguments to pass to what command.”
That’s an exaggeration, of course, but as always, there’s a grain of truth in it. So here we go:
If you need to delete duplicate e-mail messages on an IMAP server, take a look at this useful IMAP de-duplicator script:
IMAP de-duplicator – IMAPdedup
As IMAPdedup is a command line interface tool (a python script), it’s particularly useful for:
I also found that it deals relatively well with failures (e.g. when a folder is read-only and hence messages can’t be deleted): It simply reports them on the screen and carries on.
Here’s a quick’n’dirty bash script to de-dup the inbox and all subfolders of the specified account:
#!/bin/sh # Delete all duplicate messages in all folders of said account. # Note that we connect through SSL (-x) to the default port. SERVER="my.server.com" USER="mylogin" PASS="mypass" for folder in `imapdedup.py -s $SERVER -x -u $USER -w $PASS -l`; do imapdedup.py -s $SERVER -x -u $USER -w $PASS $folder done
If you only have to de-duplicate messages in a small folder, you could also use the following de-duplication add-on for Mozilla Thunderbird:
Remove Duplicate Messages Add-on for Thunderbird
Note however that the ‘Remove Duplicate Messages’ add-on is intended for interactive use only, not for batch processing. I also noticed that it fails at cleaning big mail folders (e.g. containing 50’000 messages).
I noticed that Growl constantly used 5% of the CPU on my MBA. For a mere notification system, that’s way too much. I thus decided to delete Growl, here’s how:
Textual is a heavily modified fork of LimeChat and looks and feels more native and light-weight than most other IRC clients for Mac OS X. Further, it doesn’t seem to have problems with window refreshing as observed with XChat Aqua/Azure (App Store link) and XChat for X11 (installed/compiled using ‘brew install xchat’).
Though Textual is also available in the App Store for 4.99 USD, I wanted to compile it from sources myself.
Here’s how to build Textual from sources (tested on Mac OS X Mountain Lion):
