My new current favourite theme for emacs is spolsky.
If you use elpy / highlight-indentation, you might want to define this too:
(set-face-background 'highlight-indentation-face "#1B2025")
Windows shares no longer mounting on Linux
I use autofs to mount a windows share on my router, this stopped working with “mount error(112): Host is down”.
Looks like it was due to some arch linux update, as per dmesg:
[ 5986.858242] No dialect specified on mount. Default has changed to a more secure dialect, SMB3 (vers=3.0), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 specify vers=1.0 on mount. For somewhat newer servers such as Windows 7 try vers=2.1.
Specifying version 1.0 fixed it. (Note: this is just on my home network, you might want more security elsewhere).
Fixed autofs entry:
data -fstype=cifs,vers=1.0,username=me,password=notthis,uid=me,gid=users,workgroup=HOME ://myrouter/data

emacs tip of the week #7: smex
Smex is M-x on steroids. It gives you an ido completion buffer for all commands you run this way, prioritizing more recently used to the front.
Building remacs (rust emacs) on Fedora
The equivalent to install the dependencies is:

How to migrate virtualenvs when system python version changes
eg from 3.5 to 3.6
Not foolproof, but a quick hack
# In your old virtual site-packages directory
# with your new virtualenv activated
pip install `find . -mindepth 1 -maxdepth 1 -type d | egrep -v "(info|egg)$" | egrep -v "(pycache|pkg_resources)" | sed -e 's#./##g'`

Installing variety wallpaper changer on Fedora 25
The rpm-sphere rpm doesn’t work for me.
First install some packages, you may need more, these worked for me:
dnf install libindicator-gtk3 libdbusmenu-gtk3 libappindicator-gtk3 python-appindicator \ webkitgtk3 intltool
Then create a python virtualenv & activate it.
mkvirtualenv --system-site-packages -p $(which python2) utils
Download the variety & python-distutils-extra tarballs & untar.
Install both packages into your virtualenv (python-distutils-extra first).
python setup.py install
Go to virtualenv bin directory & rename variety.py (this upsets python module import)
cd ~/.virtualenvs/utils/bin mv variety.py varietybin.py rm variety.pyc
and run
variety
nrpe systemd socket activation
If you’re using nrpe socket activation and don’t have a template file, try this in /etc/systemd/system/nrpe@.service :
[Unit] Description=nrpe socket service Requires=nrpe.socket [Service] User=nrpe ExecStart=-/usr/bin/nrpe -c /etc/nrpe/nrpe.cfg --inetd StandardInput=socket StandardOutput=inherit StandardError=journal [Install] WantedBy=multi-user.target
You’ll also need /etc/systemd/system/nrpe.socket :
[Unit] Description=Nagios Remote Plugin Executor Documentation=http://www.nagios.org/documentation Before=nrpe.service Conflicts=nrpe.service [Socket] ListenStream=5666 Accept=yes [Install] WantedBy=sockets.target Then systemctl start nrpe.socket
