Our root,
who art in Unix,
hallowed be thy shell.
Thy kernel come.
Thy commands be run
@localhost as they are in iNet.
Give us this day our daily updates,
And forgive us for our four-oh-threes,
as we forgive those who 403 against us.
And lead us not into segfaults,

# Here a few bash one-liners that helped me analyze / fight a weak DOS attack against debuggable.com. Mostly for future reference.
# The attacker was opening lots of tcp connections without sending data, I believe it's called a SYN flood, see: http://tools.ietf.org/html/rfc4987#section-3.2

# Step 0: Check what is going on at port 80
$ netstat -tan | grep ':80 ' | awk '{print $6}' | sort | uniq -c

# Step 1: Increase the number of available fds
$ ulimit -n 32000

# Step 2: Restart your webserver, for me:

Don't Buy the Snake Oil of Beamr Video

You might have heard of Beamr Video, and their impressive claims about reducing video bitrates by "up to 4x, without losing quality". Sounds too good to be true? Well, as a matter of fact, it is.

The Example Videos

The four example videos that Beamr has on their site use very high bitrates - 40-50 Mbps for 1080p video. These are the kind of bitrates you find on Blu-ray discs, whereas with something like Netflix's "SuperHD" you'd only get around ~5.6 Mbps (5800 kbps) 1080p video, and with 720p Netflix video the bitrate is only around ~3.5 Mbps (3600 kbps). If you have watched online streams like these, you'll probably know that they look quite decent. Now, if you look at the Beamr Video examples, you'll notice that even for their "reduced" clips, the bitrates are still around 9 Mbps minimum, and average as high as ~30 Mbps.

At this point, you can probably see the trick that Beamr is trying to pull
