=Mostly just for me to remember stuff=
I might use a command once, then not again for years. Hopefully I can jog my memory quickly here.

==Python==
I wanted a json utc datetime for a [http://mqtt.org/ MQTT] payload. Found the [https://github.com/crsmithdev/arrow arrow] module that is much like moment.js for javascript.

<source lang="text">
import arrow
print (arrow.get(arrow.utcnow()).for_json()

results in: "2015-08-27T15:03:07.427351+00:00" I'd like to trim it further and replace the +00:00 with Z. ??? and less precision on the seconds.

==Fedora fc.22==
I opened up node.js on port 3000 with this command.
<source lang="text">
firewall-cmd --permanent --add-port=3000/tcp
# be sure to reload
 firewall-cmd --reload
</source>

<source lang="text">
# tail a log with colored warnings
#> tail -f /var/log/maillog|egrep --ignore-case  --line-buffered --color=auto 'reject|ERROR|WARN|$'
</source>

==7-zip==
I wanted to create a .zip file for my FDDSE project from the command line. Perhaps in a batch file.
<source lang="text">
7z a -tzip FDDSE.zip FDDSE
</source>

==VS 2015 IISExpress==
<source lang="text">
.vs\config\applicationhost.config
%userprofile%\Documents\IISExpress\
netsh http show urlacl
netsh http add urlacl url=http://localhost:60262/ user=everyone
netsh http delete urlacl url=http://*:60262/
I 'ended' Microsoft.VsHub.Server.HttpHostx64.exe with TaskManager
// punch a hole in the firewall
// oopps just noticed I'm running public profile at home on nat. Another toDo
C:\Users\jeffa>netsh advfirewall firewall add rule name="IISExpressWeb" dir=in protocol=tcp localport=60262 profile=private remoteip=localsubnet action=allow
Ok.


C:\Users\jeffa>netsh advfirewall firewall add rule name="IISExpressWeb" dir=in protocol=tcp localport=60262 profile=public remoteip=localsubnet action=allow
Ok.
