Chrome caches 301 redirects in a certain way. This one caused problems when testing redirects with monitoring-portal.org with / to /woltlab (now removed).
There is no direct configuration setting for this, you need to visit chrome://net-internals/ in Chrome. Then right click on the cursor icon in the right upper corner and select “clear cache”.
I’m a heavy lldb user during Icinga 2 development. Most recently I got many of those error messages when starting lldb for debugging Icinga 2.
mbmif /usr/local/icinga2/etc/icinga2/tests (master) # lldb -- /usr/local/icinga2/lib/icinga2/sbin/icinga2 console (lldb) target create "/usr/local/icinga2/lib/icinga2/sbin/icinga2" Traceback (most recent call last): File "", line 1, in File "/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Resources/Python/lldb/__init__.py", line 98, in import six ImportError: No module named six Traceback (most recent call last): File " ", line 1, in NameError: name 'run_one_line' is not defined
Turns out that I have Python2 installed from a dependency in Homebrew. The lldb scripts just use the system path for determining the preferred Python binary.
A sensible workaround is discussed here:
$ /usr/local/bin/pip install six
Works again.

Since I wanted to check which package requires python in /usr/local/bin/python I found this command
$ brew list | while read cask; do echo -n "$cask ->"; brew deps $cask | awk '{printf(" %s ", $0)}'; echo ""; done
I can’t get rid of pygtk and macvim, so each new install/update will pull Python again. The reason why they build their own Python is somewhat unsafe C++ functions. Guess I don’t want to dig any deeper here.
I’m using Homebrew on my Macbook. It is a great addition to installing software when you are used to package managers from the Linux world.
There’s also an extension called Homebrew Cask which allows you to manage MacOS applications, such as Adium or Gimp. This saves you the hassle of manually downloading the package/dmg files and automates the installation/updates.
Lately when doing an update again, there was a notice about a changed Caskroom location.
michi@mbmif ~ $ brew cask list Warning: The default Caskroom location has moved to /usr/local/Caskroom. Please migrate your Casks to the new location and delete /opt/homebrew-cask/Caskroom, or if you would like to keep your Caskroom at /opt/homebrew-cask/Caskroom, add the following to your HOMEBREW_CASK_OPTS: --caskroom=/opt/homebrew-cask/Caskroom For more details on each of those options, see https://github.com/caskroom/homebrew-cask/issues/21913. apache-directory-studio filezilla gimp macvim vlc xquartz bitbar firefox java7 mysqlworkbench wireshark
Ok, what would I do now? “Migration” could just mean moving the directories. But wait, the installed applications could be symlinked into ~/Applications instead of being moved (#13966).
Looking into the mentioned github issue #21913 shed some light on how to fix it. Moving the directories will make “brew cask list” shut up about the changed location, but later uninstalls will fail due to dangling symlinks. The solution is simple – force an installation again after moving the installed casks.
michi@mbmif ~ $ mv /opt/homebrew-cask/Caskroom /usr/local michi@mbmif ~ $ brew cask list apache-directory-studio filezilla gimp macvim vlc xquartz bitbar firefox java7 mysqlworkbench wireshark michi@mbmif ~ $ for cask in $(brew cask list); do brew cask install $cask --force; done
