Since I was talking about security anyway…. this is a nice toy for breaking open laptops or desktops when the administrator forbade the installation of software, or you want software on it executed. This is often the case with company devices, e.g. the laptops which are supplied by banks to their 3rd party suppliers. Outsourcing is cool, remember?

This is a computer on a stick which can run a Linux kernel. In combination with some USB gadget kernel modules, it can be configured to authenticate itself as any device. All you need to do is plug it in, and iterate by brute force through the device identifiers until you hit one which is accepted to be used. Store the statically linked software you want to install or run on the stick beforehand, and here you go. So if you ever need a SSH client on a “secure” Windows laptop… putty.exe FTW.

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.
