Mavericks disorders the windows within my "desktops"

That's rather bad with my long running applications like the Chromium browser or my virtual machines running within VirtualBox. I have to stop the browser or even VirtualBox itself. And just a few minutes "ago", VirtualBox even aborted abruptly without saving the states of the virtual machines. I hate that.

resetting the DNS cache: OS X, Firefox

 This is the manual approach for Firefox:
  • Introduce 2 new variables within about:config:
  • network.dnsCacheExpiration (integer / 0)
  • and network.dnsCacheEntries (integer / 0);
  • my problem with this: if you want to reset these switches, that's fine with Firefox, just that they get their data types changed to "string"; and once, you want to set them again to "integer / 0", you simply can't; for the time being I just assume, Firefox doesn't seriously consider the data type and accepts "string" for these 2 as well.

Mac OS X "Quick Look Preview" vs copy+paste



(I only quote this reference to give them some honour.)

$ defaults write com.apple.finder QLEnableTextSelection -bool TRUE # activate!
$ killall Finder # only a Finder started after the last command will obey
$ defaults read com.apple.finder QLEnableTextSelection # so what's the current value?

the Fink project

packages I use:
  • coreutils
  • wget
  • xv
  • xpdf

upgrading to Mac OS X Mountain Lion

  • starting with Mountain Lion X11 for Mac OS X is available on a separate website: xquartz.macosforge.orgsupport.apple.com/kb/HT5293
  • RCS binaries get provided in /Developer/usr/bin, but e.g. "rcsdiff" makes use of a hard-wired "co" by the full path of /usr/bin/co; my fix for this: I symlinked ../Developer/usr/bin/co to /usr/bin/co.
  • you need XCode of course
  • as a Fink user, you need to (re-)install Fink from fink.sf.net (coreutils, wget, xv, xpdf)

downloading Apple's Xcode from the "Mac App Store"

Xcode Downloads and Resources - Apple Developer


  • You decide, you need XCode,
  • you are going to the Mac App Store,
  • you are pressing the Install button,
  • going to download 1.65 GB,
  • and the only feedback you are getting for quite a while is the button saying "Installing".

how to always boot Mac OS X in Verbose Mode

Always boot Mac OS X in Verbose Mode

As with Linux for me it's a must to see the thing working on something and exactly what, instead of staring at a graphical screen to indicating anyhow, why it forces me to wait.

O'Reilly Media book: Mac Hacks

Mac Hacks:
OS X Mountain Lion is an incredibly powerful, but if you’re a serious Mac user who really wants to take control of this operating system, this book helps you dig below the surface. Tweak system preferences, mount drives and devices, and generally do things with your system that Apple doesn’t expect you to do.

Google Chromium constantly asking for Keychain permission on OS X? - Super User

osx snow leopard - Google Chrome constantly asking for Keychain permission? - Super User

Having read the above article, I thought I should remove the  "Chrome Safe Storage" in the "Keychain Access", before I launch Chromium. Somehow I got the impression, that would help. Usually I have to keep ESC pressed to answer all the keychain access requests.

Update 2013-01-23:
In the meantime I don't think any more, that it really helps.

GNU Emacs for Microsoft Windows resp. Mac OS X


O'Reilly's web page for "Learning GNU Emacs, 3rd Edition" [Link] points for Mac OS X and Windows implementations exclusively to these web pages, but pls regard both as outdated:
  • http://sourceforge.net/projects/nqmacs/
  • http://www.apple.com/downloads/macosx/unix_open_source/carbonemacspackage.html

how to reach the usual "alt-..." keyboard bindings with an emacs from emacsformacosx

GNU Emacs For Mac OS X – this is the emacs, I am referring to here.

OS X and emacs use the "alt" key differently, so how do I achieve on OS X within emacs what I usually achieve with "alt", like entering "[" through alt-5?

I sacrificed the right "alt" key to work the Mac OS X way (by setting ns-right-alternate-modifier to none), and the left "alt" key to work the emacs way.

Enter this within your emacs (from emacsformacosx.com) on OS X:

M-x customize-group ns


bdecaf
 suggested that in a thread on stackoverflow.com [Link].


Now I can enter "[" on my Austrian/German Mac keyboard through (right) alt-5.

I had waited far to long, before thoroughly investigating this.

ssh-ing from OS X into a Linux on a local VM (VirtualBox)


  • for the specific virtual machine: Network Adapters / Port Forwarding / add a rule like "Protocol=>TCP, Host Port=>2222, Guest Port=>22, leave the IP addresses blank!"; the VirtualBox help system opens a nice and very instructive PDF manual, that really made me feel comfortable with this
  • this way you should actually be able to "ssh -p 2222 localhost" on the host machine
  • in my case this failed, complaining like this: "port 2222: Connection refused"
  • it took me a while to reason, whether the guest OS really has an ethernet / LAN interface configured – and there wasn't any such active interface – TBD
To be continued …

Update 2013-02-26:
"Bridged networking" looks superior to NAT, as things work far more easily – you don't need to forwards ports (e.g. SSH), you can simply talk to the VM guests. I couldn't get Samba working with NAT's port forwarding, but with bridged networking "it's just there" (what a joy!!!), and you can also have "natural" communication amongst the guests. Imagine: an Oracle DB within some VM …
