# As the "bufferbloat" folks have recently re-discovered and/or more widely
# publicized, congestion avoidance algorithms (such as those found in TCP) do
# a great job of allowing network endpoints to negotiate transfer rates that
# maximize a link's bandwidth usage without unduly penalizing any particular
# stream. This allows bulk transfer streams to use the maximum available
# bandwidth without affecting the latency of non-bulk (e.g. interactive)
# streams.

How to install NVIDIA Docker 2 package on Ubuntu and Debian:

If you came to this result (from Google or elsewhere) after realizing that Nvidia-docker's entry on this subject does not result in a working installation, here are the basic steps needed to install this package correctly:

For starters, ensure that you've installed the latest Docker Community edition by following the steps below:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Setting up analog surround sound on Ubuntu Linux with a 3 3.5mm capable sound card:

A while back, I received the Logitech Z506 Speaker system, and with Windows, setting it up was a pretty plug and play experience. On Linux, however, its' a wholly different ballgame. For one, there's no Realtek HD Audio control panel here, so what gives? How do you around this problem?

Introducing the tools of the trade:

You'll want to use a tool such as hdajackretask , pavucontrol and pavumeter for the pin re-assignments and audio output monitoring afterwards respectively. The tools are installed by running:

sudo apt-get install alsa-tools-gui pavumeter pavucontrol

Overclocking the P751DM2-G with the Prema Mod BIOS v 1.06.09PM v2.2:

Hello guys,

A while back, Prema and I flashed the Prema Mod BIOS on the aforementioned chassis, the P751DM2-G (Branded as the Origin Eon 15-X) and I proceeded to make a few tweaks to the machine to suit my purposes:

1. Applied a mild overclock to the processor, setting all multipliers on the Intel Core i7 7700k to 4.5Ghz.

2. Applied an AVX offset of 1.

lsusb lists the fingerprint reader in the x240 as follows:

Bus 002 Device 003: ID 138a:0017 Validity Sensors, Inc.

There exists experimental driver support for this in a fork of libfprint for vfs5011 sensors, however you'll need to compile the driver yourself. To get the fingerprint sensor to work for lightdm login, su etc, follow these steps.

1. Install fingerprint-gui:
