Sometimes when you want to fork a branch and push your exisiting work, github rejects your push (sometimes caused by being offline). git st looks fine.
When I tried to push, it showed this:
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://github.com/something.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing

Good commit messages serve at least three important purposes:
To speed up the reviewing process.
To help us write a good release note.
To help the future maintainers of Erlang/OTP (it could be you!), say five years into the future, to find out why a particular change was made to the code or why a specific feature was added.

After reboot, gnome got stuck right after the purple "ubuntu" with several dots below, then only one non-flicking cursor on the top left. Then into recovery mode, try startx it says
X: cannot stat /etc/X11/X (No such file or directory), aborting
sudo dpkg-reconfigure xserver-xorg-lts-utopic
This restores the symlink /etc/X11/X -> /usr/bin/Xorg. I've tried to modify lightdm to gdm doesn't work. And xorg dpkg reconfigure doesn't work because I don't have it installed. I found I have xserver-xorg-lts-utopic.
LinSSID is a graphical and functional wifi scanner for Ubuntu Linux, which is similar to iwscanner and Inssider. It can be easily installed in Ubuntu and Linux Mint via PPA repository. (Kismet didn't work for my Ubuntu 15)
sudo add-apt-repository -y ppa:wseverin/ppa
sudo apt-get update; sudo apt-get -y install linssid

My goal was to set up Flume on my web instances, and write all events into s3, so I could easily use other tools like Amazon Elastic Map Reduce, and Amazon Red Shift.
I didn't want to have to deal with log rotation myself, so I setup Flume to read from a syslog UDP source. In this case, Flume NG acts as a syslog server, so as long as Flume is running, my web application can simply write to it in syslog format on the specified port. Most languages have plugins for this.
At the time of this writing, I've been able to get Flume NG up and running on 3 ec2 instances, and all writing to the same bucket.
