If for some reason postfix isn’t resolving reverse DNS (and giving “unknown” in headers) then you might have configured some of your daemons to run in a chroot without copying the necessary configuration files in, do this by running the appropriate script for your platform under examples/chroot-setup.
The DCS-932LB1 webcam from D-Link is a very naughty webcam that pretends it has turned off upnp when it hasn’t. This is a security hole, opening up your webcam to the world and D-Link don’t seem to care. The best thing to do is disable upnp completely in your router, however you might need it. …

Hopefully you are already using ido or something similar to enhance emacs tab completion. I only use ido-switch-buffer ((ido-mode ‘buffer) in .emacs) as I dislike ido-find-file. What I don’t like is accidentally typing \C-x\C-b for buffer-menu-other-window (or whatever it is) when I meant \C-x b. So I put this in .emacs: (global-set-key “\C-x\C-b” ‘ido-switch-buffer)
Keeping things simple (and independent) is very important in my opinion. But since it is often faster (at the beginning), and especially needs much less thinking and experience to make things unnecessarily complex, that’s unfortunately what most people do… So, the purpose of this site is to show some “simple alternatives”—or at least some “things”, …

Get a raspberry pi, install raspbian on it and put it on your home network Install smokeping (apt-get install smokeping) Configure smokeping (edit /etc/smokeping/config.d/Targets) so that at least one of the targets is a stable internet host (eg Google DNS 8.8.8.8). Restart View http://rasp-pi-ip/smokeping/smokeping.cgi Get sad results like the below 🙁
Nginx supports dynamic modules now: http://mailman.nginx.org/pipermail/nginx-announce/2016/000170.html This was previously a big advantage in favour of Apache (unless you really enjoy recompiling).
Are you an emacs user? Are you a GNU screen user? If the answer to both of these questions is yes then install elscreen for buffer navigation in emacs.
So here’s a quick function to drop in your ~/.emacs (taken from here): (defun git-push-remote-origin () “run `git push'” (interactive) (when buffer-file-name (shell-command “git push”) (message “DONE! git push at %s” default-directory) ))
