Should return them in the same order as

Ubuntu Theme – Arc or Materia

# Install Arc soft fork
sudo add-apt-repository ppa:fossfreedom/arc-gtk-theme-daily
sudo apt-get install arc-theme
gsettings set org.gnome.desktop.interface gtk-theme 'Arc-Dark'

sudo add-apt-repository ppa:dyatlov-igor/materia-theme
sudo apt install materia-gtk-theme
gsettings set org.gnome.desktop.interface gtk-theme 'Materia-dark-compact'

sudo add-apt-repository ppa:daniruiz/flat-remix
sudo apt-get install flat-remix
gsettings set org.gnome.desktop.interface icon-theme 'Flat-Remix-Dark'

Ubuntu Bash Git Branch Prompt!

# Git branch in prompt.
parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'

export PS1="${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]:\[\033[32m\]\$(parse_git_branch)\[\033[00m\]\$ "

This is compatible with the default colour prompt in Ubuntu 16.04, put this in you ~/.bashrc.

Original version (non Ubuntu specific)

Bitmain’s new payment system is broken for LTC/L3+ miner. Support just say wait

UPDATE: Bitmain did eventually respond and fix mine and others orders but it took 8 days without any response in between.

Quite a few people have recently purchased L3+ miners using LTC. (Previous orders using BTC have worked fine). Bitmain are taking the money but not updating the order status.

Their support is not responding to tickets apart from just saying please wait longer (it’s been 4 days for me)

The problem is the orders expire in 1 hours and they are don’t appear to either be updating the orders for the limited batch or refunding people their payments.

There are also reusing payment addresses which will make working out who payed for what very hard as you will have customer payments to the same address.

Have a look down at the comments here and here

You can see the payment wallet address reuse here

The final wallet is here (probably BitMain but it looks like it goes through a mixing service so it might not be)

Rebuilding FFmpeg with NVENC and AAC on Ubuntu

This mini guide will show you how to rebuild the exact version of FFmpeg that comes with your version of Ubuntu and just add support for NVidia GPU encoding via the NVENC API and ACC via libfdk_aac.

# Download and unzip the NVIDIA Video Codec SDK from

# Copy the headers files from the SDK so FFmpeg can find them
sudo cp nvidia_video_sdk_6.0.1/Samples/common/inc/*.h /usr/local/include/

# Make sure "Source code" is enabled in System Settings... -> Software & Updates
# Download the build dependencies for FFmpeg
sudo apt-get build-dep ffmpeg

# Install libfdk_aac
sudo apt-get install libfdk-aac-dev

# Download the source for the exact version of FFmpeg you already have installed (not as root)
apt-get source ffmpeg

# Go into the ffmpeg source you just downloaded
cd ffmpeg-2.8.6

# Find out the exact command the ffmpeg was originally built with
ffmpeg -buildconf

# Copy the single line "configuration:" and pass it to ".configure" but add "--enable-nonfree --enable-nvenc --enable-libfdk-aac" on the end
# Mine looks like this:
./configure --prefix=/usr --extra-version=1ubuntu2 --build-suffix=-ffmpeg --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --cc=cc --cxx=g++ --enable-gpl --enable-shared --disable-stripping --disable-decoder=libopenjpeg --disable-decoder=libschroedinger --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librtmp --enable-libschroedinger --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzvbi --enable-openal --enable-opengl --enable-x11grab --enable-libdc1394 --enable-libiec61883 --enable-libzmq --enable-frei0r --enable-libx264 --enable-libopencv --enable-nonfree --enable-nvenc --enable-libfdk-aac

# Now build it

# And finally install it over the original
sudo make install
