Launch & Run Multiple Instances of Any Application in Mac OS X

Posted by jpluimers on 2017/04/17

I needed a second instance of Atom to run on a second monitor:

open -n /Applications/Atom.app

Or even shorter:

open -na Atom

I got there via: Launch & Run Multiple Instances of Any Application in Mac OS X

The reason is that searching for Mac OS X start second Atom instance does not reveal satisfactory results, as the tips in these links all fail:

Getting your local IPv4 addresses, netmasks and CIDRs

Posted by jpluimers on 2017/04/11

In order to scan some local networks for unknown hosts (yes, on some sites you need to perform archeology), I needed the local IPv4 addresses, netmasks and CIDRs on my Mac running OS X.

Part of that is using ifconfig to get local inet information which however uses hexadecimal network masks and delivers no CIDRs.

SoI was a bit premature when I wrote about “This could be done by creating bash functions mask2cdr and cdr2mask, but that’s a bit too convoluted right now” in Getting the IP addresses of gmail MX servers – via Super User – dig isn’t enough.

netmask to CIDR and CIDR to netmask conversion

I need mask2cdr now, so lets start with these two bash functions and their aliases:

OS X – the versions and their names – as I always forget them

Posted by jpluimers on 2017/04/03

I always forget which OS X versions there are and which names they use.

So via: OS X – Wikipedia, the free encyclopedia, I made this list where the first item points to the table in the above article and each subsequent item to the individual article on the version. I tried to find EOL dates, but that’s hard despite the overview at Apple security updates – Apple Support:

None of this would be noteworthy if Apple, like Microsoft and a host of other major software vendors, clearly spelled out its support policies. But Apple doesn’t, leaving users to guess about when their operating systems will fall off support. | Computerworld

PS: EOL dates are as of 20160403.

Mac OS X: restarting Tunnelblick when it isn’t responding any more

Posted by jpluimers on 2017/03/31

In addition to my post about Mac OS X: restarting Google Drive when it shows a spinning wheel, restarting a hanging Tunnelblick is even easier:

killall Tunnelblick
open -a Tunnelblick
