rsync z-lib compression segmentation fault? WTF!

Posted by jpluimers on 2017/07/27

Not sure why without the -z compression switch this succeeds:

# rsync -avloz /var/lib/named/master/ /etc/named/master/
sending incremental file list
pluimers.com
Segmentation fault (core dumped)
# rsync -avlo /var/lib/named/master/ /etc/named/master/
sending incremental file list

The strange case of some applications not being able to copy/paste on the Mac OS X clipboard

Posted by jpluimers on 2017/07/19

I’ve not tracked down the cause yet, but these seem to be related:

  1. The Mac OS X build of Atom IO
  2. WinBox v 3.4 WineBottle version from Winbox for Mac in an embedded Wine environment – Joshaven.com
  3. pbcopy / pbpaste that allow command-line copy/pasting
  4. none of these being able to copy/paste any more and return error level 1 like terminal – pbcopy exits code 1, no error message – Ask Different but not even running tmux or screen which means this solution does not apply: ChrisJohnsen/tmux-MacOSX-pasteboard: Notes and workarounds for accessing the Mac OS X pasteboard in tmux sessions.
  5. I didn’t have Mouse Keys turned on
  6. Other applications (Chrome, FireFox, TextEdit, Finder, etc) still being able to copy/paste between each other

I’ve “fixed” 4. by doing this as recommended at osx – Copy and Cut sometimes don’t work – Ask Different:

launchctl list | grep com.apple.pboard

If the pboard daemon is running, then stop and start it. If it’s not running, start it:

launchctl stop com.apple.pboard
launchctl start com.apple.pboard

Now 4. works again if I restart each application, 6. still works, but these applications still cannot copy/paste to 1. 2. and 3.

What does work is a full reboot, but that takes a while (especially Chrome re-loading lots of Windows: I need to get more organised here).

It might be that I need to restart each application in 6.

Grrr…..

Happy #NoEmailDay – The case of the 500-mile email

Posted by jpluimers on 2017/07/07

Good reading on #NoEmailDay 2017: The case of the 500-mile email [WayBack] on how a sysadmin in the mid 1990s found the cause of not being able to send email further than roughly 500 miles.

The exact mile unit doesn’t matter as it was all approximation. Read the FAQ on the 500-mile email [WayBack]
