fixing a Mac home `brew update` that has permission errors (after that I could install plantuml)

Posted by jpluimers on 2017/01/26

I had this occurring on my system:

RetinaMBPro1TB:~ jeroenp$ brew update
error: unable to unlink old 'Library/ENV/pkgconfig/10.11/libcurl.pc' (Permission denied)
error: unable to unlink old 'Library/ENV/pkgconfig/10.11/libxml-2.0.pc' (Permission denied)
error: unable to unlink old 'Library/ENV/pkgconfig/10.11/sqlite3.pc' (Permission denied)
To restore the stashed changes to /usr/local run:
  'cd /usr/local && git stash pop'
Already up-to-date.

This is how I solved it:

RetinaMBPro1TB:~ jeroenp$ ls -al /usr/local | grep -w Library
drwxr-xr-x+ 11 jeroenp  admin   374 Mar  9 19:33 Library
RetinaMBPro1TB:~ jeroenp$ sudo chown -R $USER /usr/local/Library/
Password:
RetinaMBPro1TB:~ jeroenp$ brew update
To restore the stashed changes to /usr/local run:
  'cd /usr/local && git stash pop'
Updated Homebrew from d32996d to 638d755.
==> New Formulae
...
==> Updated Formulae
...
==> Renamed Formulae
...
==> Deleted Formulae
...
RetinaMBPro1TB:~ jeroenp$ 

The above solution is based on major python problems · Issue #48301 · Homebrew/homebrew

After that, I could install plantuml (which requires java, just so you know) so now I can create SVGs from it locally:

plantuml -tsvg PSO.network-diagram.PlantUML.txt

Note I had to edit the formula so it installs plantuml-8037 or higher (the git version back then installed plantuml-8031) as it fixed a namespace bug. Since plantuml releases often, be prepared to do some version fiddling.

whatismylocalip alias (actually more like whataremylocalips) and some sed links

Posted by jpluimers on 2017/01/10

Getting the local IP (actually IPs, but most hosts only have a single IP):

# OS X:
alias whatismylocalip='ifconfig | sed -En '\''s/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'\'''
# Linux:
alias whatismylocalip='ip a | sed -En '\''s/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'\'''

I got them via bash – How to I get the primary IP address of the local machine on Linux and OS X? – Stack Overflow

Mac OS X and BSD have ifconfig, but most Linux distributions don’t use ifconfig any more in favour of iproute2, so you use ip a (which is shorthand for ip address show) there.

Their output is similar enough for the sed to work, though. Which surprised be because I didn’t know about the -E option (it lacks in the manual Linux page but it is in the Mac OS X one) which enables POSIX extended regular expressions. In Linux this is documented as -r, but -E also works.

I learned this through the Sed – An Introduction and Tutorial which compares the various versions of sed which also explains about the -n doing no printing.

You cannot create an iTunes Store, App Store, or iBooks Store account without a credit card. You  – Apple Support

Posted by jpluimers on 2016/12/09

So I gave my mom an iPad. But she doesn’t have a credit card. As having one is not usual for Dutch people, especially for elderly Dutch people. Why would you need one if you can pay anything you require online with your Bank Card?

Well: from an iPad, you cannot sign in to iTunes without first adding a credit card. There is no other way. No bank account (which is very common in Europe). No iTunes voucher. No nothing. This is what you have to do:

If you’ve already created your Apple ID, you’ll need to add a payment method when you first use it to sign in to the iTunes Store, App Store, or iBooks Store. But you can optionally remove the payment method after you sign in to the store. You won’t be asked for a payment method again until you make your first purchase.

I haven’t even checked iTunes for on her PC, as iTunes is so utterly user unfriendly (for instance you cannot drag-drop music to your iPad from a folder. You need iTunes and I’d need to explain here about all sorts of clouds other than where rain comes from) that I won’t even try to teach her how to use it.

What I finally did is add my own credit card (apparently they don’t do name or address checks), then remove it.

Inspecting/unpacking a Linux rpm file on Mac OS X

Posted by jpluimers on 2016/11/18

You need this statement to unpack an rpm file on Mac OS X without having rpm installed:

rpm2cpio ##filename.rpm## | cpio -idmv

This will make rpm2cpio unpack the rpm file in the current directory using these cpio options:

  • i – use the rpm2cpoio as unput
  • d – created directories when needed
  • m – set modification timestamps from the archive
  • v – verbose filenames to stderr

cpio is already part of the Mac OS X system.

You can get rpm2cpio through homebrew by typing brew install rpm2cpio which will likely also download he xz dependency.

`xcode-select –install` required for OS X 10.9 Xcode command-line tools (like `zlib-devel`)

Posted by jpluimers on 2016/11/16

Hopefully this was a one time oversight from Apple, but on OS X 10.9 (Mavericks) the Xcode command-line tools cannot be installed from the Xcode Preferences pane.

You have to install them from the command-line:

xcode-select --install

There is one catch though: it might fail as you first have to start Xcode once and accept the license agreement.

You need them for instance when playing with zlib-devel (for instance when creating your own openssl builds).

How to use curl command with http/2 on MacOS X

Posted by jpluimers on 2016/11/04

Skip the built-in curl and directly go to the homebrew one:

$ brew update
$ brew upgrade
$ brew install curl --with-nghttp2

display – How can I move spaces between external monitors in Mavericks? – Ask Different

Posted by jpluimers on 2016/10/21

display – How can I move spaces between external monitors in Mavericks? – Ask Different [WayBack]

You can only move spaces which are non-active.

For example, lets say you have spaces 1 and 2. If space 1 is active, you can not move it. You first have to select space 2 then you can move space 1 to a different monitor.

This helped me work around version 8.35 of Microsoft Remote Desktop for OS X breaks second monitor usage [WayBack]:

  1. Double click a connection so it goes to a new space on the primary display
  2. Make the normal space active (by three finger swiping on the primary display)
  3. Go to mission control
  4. Move the non-active RDP space to the secondary monitor

Sometimes the primary monitor doesn’t have a non-active space any more so you have to create a new one in the top right of Mission Control [WayBack].

Some notes on modifying NIB files on Mac OS X to add/change shortcuts

Posted by jpluimers on 2016/10/19

One of the nitpicks in VMware Fusion is that it has no keyboard shortcut for Resume or Suspend. I was trying to add Command-R and Command-S for those but that didn’t work out.

Since the links below seem to work for some other applications, I’ve kept them:

Wish ttystudio was available for OpenSuSE and Mac OS X…

Posted by jpluimers on 2016/10/10

Really interesting stuff: ttystudio. It allows to record an apng or gif of a terminal session (so it should work on headless systems).

Anyone knowing alternatives for OpenSuSE and Mac OS X?

(Cockos Incorporated | LICEcap might cut it on Mac OS X, but not on headless systems so GNOME/byzanz doesn’t cut it either)

Handy as well:
