UBUNTU15_INSTALL.md

Ubuntu 15.10 Install

This is all installed on a 15" MacbookPro 2013. That's the 11,3, which was released in October 2013. this will be nearly the identical config for the 11,2 as well, although I think the 11,1 is missing an nvidia graphics card .. maybe? i donno. it will be mostly the same the 12,1 and 12,x series. honestly .. i'm just bullshitting here and trying to cover my SEO bases lol.

initial software

download build stuffs

sudo apt-get install build-essential cmake autoconf git vim

copy ssh keys and ssh-add ~/.ssh/id_rsa

setup git config:

git config --global user.name "David Conner"
git config --global user.email "dconner.pro@gmail.com"
git config --global core.excludesfile ~/.gitignore_global

# after cloning .files:
ln -s ~/.files/git/gitignore_global.ubu ~/.gitignore_global

q

privacy

Hit Super and type privacy and hit Enter. Navigate to the Files & Applications tab. Turn it off. If you're a programmer, you don't need that. Uncheck all the boxes. Click 'Clear Usage Data'.

Use Find+Grep: grind() { find . -type f -exec grep --color -nH -e $1 {} +

One reason I love emacs: it uses mostly GNU tools and is magnificent in exposing it's interface to you to show you the options available and how it does things. Learn how to use apropos to discover it's functionality.

Next: Click the Search tab and tell it to exclude online results. Also, you may want to exclude error reports.

Now, install Unity Tweal Tool with sudo apt-get install unity-tweak-tool. Open it.

There are some duplicate configurations here, but also more options. To me, it's a bit irritating that the default Unity interface is so simplified, but I guess I understand why. However, for me personally, I like all my configuration for an OS/App in one place and searchable. IntelliJ and Android are two excellent examples of configuration UI's that are robust and easily discoverable.

loxodo password safe

It is a small tragedy, but there are no pwsafe managers for linux that:

(1) I trust. A password manager written in high-level language such as TCL really needs some thought.

(2) Build easily without sketchy dependencies

loxodo is a small command-line and GUI capable system for opening password files.

# i've got this one memorized sudo apt-get install
git@github.com:sommer/loxodo ~/src/loxodo

now put your password file where you want it and keep it on USB. also, you can keep loxodo on USB and load it as needed. luks that ish.

./loxodo.py -i [psafe3file] to run in interactive mode. this can also be run in GUI mode, which I feel is less trustworthy. close the app when you're not using it. you can set a shortcut to open it, but be careful.

installing loxodo with GUI:

sudo apt-get install python-wxgtk2.8
cd ~/src/loxodo
sudo ./setup.py install

dotfiles

clone dotfiles

git clone git@github.com:dcunited001/dc.files ~/.files
cd ~/.files
git submodule init
git submodule update # and if you're not me, my repos from bitbucket will fail to d/l

run init scripts with ./init/ubu.sh and follow instructions. this isn't is a complete config, but it's close enough. some of the stuff is outdated. i don't completely configure vim any more. the emacs init scripts are also outdated. i mostly just use it to set up links for zsh.

./init/ubu.sh

link emacs. i now use purcell/emacs.d

ln -s ~/.files/emacs.d ~/.emacs.d

now link the customizations

download and update the thesaurus

fonts

i like having symbola fonts and setting all fonts to deja vu w/ powerline. these powerline patched fonts can be found in my dotfiles. copying these fonts to ~/.fonts should make them available to the system.

cd ~/.files/
mkdir ~/.fonts
cp -R ~/.files/powerline-fonts/**/*.ttf ~/.fonts

now, just hit the super key, type fonts and hit enter. that should open the Font Viewer. verify that everything is there.

terminator profiles

sudo apt-get install terminator

Here, i just

TODO:

HiDPI

instead of tweaking fonts for each setting, go to Display under System Settings and change the font scaling to 1.5 or 2.0, whatever you prefer. For most apps, this fixes most problems for UI font size. Emphasis on MOST !@#$ ! $@#! $@ $!.

Jetbrains IntelliJ (and Rubymine) was still acting up. The problem was that UI fonts scaled properly, but not the code I was reading. I needed to create a custom theme in order to change it's font size. I scaled it to 22 and this fixed my problems.

Emacs was also giving me shit. So i needed to fix the fonts in that application on a one-off basis as well. Sorry, this is just dumb and means that when i reinstall my system, i have two dozen random system preferences to apply in random places in order to get things back to the way the were. And this makes me very very angry.

xkb

yeh, turns out the problem was the format of xml (forgot to put configItem tag inside variant tag)

• moved io to /usr/share/X11/xkb/symbols
• configured evdev.xml in /usr/share/X11/xkb/rules/evdev.xml
• swapped values for and in /usr/share/X11/xkb/keycodes/evdev
• echo 2 | sudo tee /sys/module/hid_apple/parameters/fnmode to fix fn keys for session
• echo options hid_apple fnmode=2 | sudo tee -a /etc/modprobe.d/hid_apple.conf to fix function keys for subsequent sessions
• after updating hid_apple.conf need to copy this config to initramfs with sudo update-initramfs -u -k all
• after reboot, everything seems to work

touchpad fixes

when you use a macbookpro outside of OSX, you really begin to appreciate whatever magic apple works with those touchpad drivers, because this shit sucks out of the box. it works pretty well in linux, i guess. but you really need to get some custom drivers running in Ubuntu, bc that shit drives me crazy. i'm always misclicking things and scrolling/highlighting and i enjoy the multitouch drivers occasionally.

download mtrack & remove synaptics

yeh, by the way, fucking mtrack stomped on my webcam. so now i gotta figure out why that shit doesn't load...

emacs

i need emacs 25 for several Melpa package dependencies included in purcell/emacs.d

deps

sudo apt-get build-dep emacs
sudo apt-get install texinfo libx11-dev libxext-dev libgtk-3-dev \
  libncurses5-dev libjpeg-dev libpng-dev libtiff5-dev libjpeg-dev \
  xaw3dg-dev libxmu-dev libxmuu-dev libxpm-dev libxt-dev libxtst-dev \
  libxv-dev libgif-dev

# libungif4-dev libxtrap-dev
# x-dev xlibs-static-dev

build

cd ~/src/emacs
./autogen.sh
./configure
make
make install

link configs

ln -s ~/.files/emacs.d ~/.emacs.d

link custom configs

ln -s ~/.files/emacs/init-local.el ~/.emacs.d/lisp/

copy thesaurus to ~/.files/emacs

A brief detour into emacs

Open emacs and it should automatically download the necessary packages.

shell emacs

This will take about 5 minutes. There's a lot of software. This makes me nervous. If you didn't build or download Emacs 25 the elisp packages won't download and you're emacs will be baroque like a harpsichord.

You'll want to configure a theme because the default one is ugly, so hit M-x, type customize-themes and hit Enter. This brings you to the themes configuration panel. Some themes are a security risk, so it may be wiser to stick with some of the defaults. Uncheck the themes you don't want and check the one you do, this save the configuration by navigating over the button and hitting enter.

I like the Cyberpunk theme, which I have to download. If you need to download a theme, hit M-x list-packages and Enter. This lists the packages available to download from Melpa. Now hit C-s to begin I-search. Now, type cyberpunk and Enter to bring your curser over the cyberpunk-theme line. Now, hit ? to see your options for the list packages screen. This works for most emacs menus. Notice, you mark packages with i. So, hit qto escape the packages screen. If you're hovering over thecyberpunk-themeline, hitito mark it, thenxto download all marked packages. You'll also need to hity` to accept them.

Magit is your best friend. It's the emacs git package and you can do anything. Again, Magit exposes the git command line interface to you and if you don't know that very well, you can easily learn it with Magit. You can send emails from emacs

If you want to learn Emacs (or Linux) the first thing you need to know is how to discover information. If you don't learn this, you're going to have problems for a long, long time. For Linux, this means learning things like how to use less commands to search man pages. Every time you hit Google to search StackOverflow, there is a way to discover that information without the internet that is 20x faster! Another thing to learn with Linux is where log files are stored and where configuration files are stored. A great quick tip for linux beginners is to learn to search your history with history | grep XXXXX. This allows you to rediscover commands you've used before.

For Emacs, this means learning to use Apropos. If you need to search for a function, type C-h a to open apropos search. Type the partial name of the command you're looking for. EVERY BUFFER IS TEXT! so you can search anywhere with C-s to open I-search. If you run into problems on a menu screen, hit ?to see your options. You can run shell commands ondiredscreens, which contain file listings using!` and typing the command.

The greatest advantage of Emacs for programming is the REPL. For small programs in scripting languages, you can run a repl and re-evaluate classes on the fly. It gets a bit more complicated if you're trying to build a module in python. There are even greater advantages to using the REPL if you're building a lisp like clojure and with clojure, you can even connect to remote REPL's!

With the REPL, you can also dynamically re-evaluate a class and run it's tests without having to re-evaluate your environment. For large frameworks like Ruby on Rails, this translates into MASSIVE TIME SAVINGS. But the configuration and learning curve of emacs often prevents people from getting to that point.

Also, emacs is configured via elisp, which is an awesome introduction to lisp and functional programming. It's magical. So by learning emacs, you're learning to be a better programmer. But often, it's better for beginners to just use a common IDE.

Anyways, moving on... (i'll like convert the above to a blog or something)

wireless

sudo apt-get install bcmwl-kernel-source

restart after wireless finishes installing. you may need to upgrade your initramdisk. this is done with.

webcam

deps

uname -r # to identify kernel version for linux-headers
sudo apt-get install linux-headers kmod checkinstall

get source

git clone git@github.com:patjak/bcwc_pcie ~/src/bcwc_pcie
cd ~/src/bcwc_pcie

then build firmware. make should download the drivers

cd firmware
make
sudo make install

build

cd ~/src/bcwc_pcie
make

Make sure you run sudo modprobe -r bdc_pci to remove the bdc_pci module before running checkinstall or any other commands. Otherwise, you'll run into some really irritating issues where the facetimehd module is installed (so checkinstall won't do anything) but not loaded. In other words, you'll need to undo all changes from the subsequent script block in order to reinstall everything properly and end up with a /dev/video device. If you don't have a /dev/video you failz and cheese won't load with a webcam.

sudo checkinstall
sudo depmod
sudo modprobe facetimehd

apparently there are problems with keeping the cam on if the laptop sleeps. see the wiki for more info

also, if there are startup problems with bdc_pci being loaded first, this should force facetimehd to be loaded first, blocking bdc_pci.

echo "facetimehd" | sudo tee -a /etc/modules

nvidia

installed with run.sh because that works better with CUDA. downloaded at CUDA Downloads

sudo apt-get install kernel-headers-`uname -r`
sudo sh cuda_7.5.18_linux.run

So this installed the nvidia drivers and CUDA software

Macbook Pro Brightness Keys

Do this after configuring nvidia. Otherwise it will be reset.

sudo setpci -v -H1 -s 00:01.00 BRIDGE_CONTROL=0

rEFInd Config

after nvidia and other updates, init ram disk needs to be updated. you'll need to do this whenever you upgrade the kernel and sometimes when you add new devices.

So if you're using refind, this means you'll need to update the vmlinuz and init ram disk images on your EFI partition. Since it's small, you'll need to delete the old ones. If you're EFI is signed (and it should be) or if your drives are encrypted (and they should be) this process will be a bit more involved...

I wish I knew of an automated way to do this. I'm sure there is one, but since your rEFInd config is personally configured, it's hard for an OS on your system to update it arbitrarily. See notes about rEFInd security. It is incredibly important because if not properly configured, you get locked out, or you provide an adversary with physical access and limited time (< 15 mins) with super-root access.

For more info on properly restricting access to rEFInd, see my blog post for a high level overview.

monitoring tools

installed perf to see why kworkers were being spawned which consumed 100% of one core, constantly.

install perf dependencies:

sudo apt-get install linux-tools-common linux-tools-`uname -r` linux-cloud-tools-`uname -r`

run perf to monitor for 10s

sudo perf record -g -a sleep 10

view perf report

sudo perf report
sudo perf report --sort comm # for higher level view

still wasn't able to deduce what was causing this wierd CPU behavior though

updating kernel from mainline

i wanted to get the latest kernel version (at least 4.4) so I configured my system to install an upstream kernel from mainline.

so, i connected to the mainline index and found the v4.4 listing, then downloaded the proper deb's for my arch to ~/src/mainline/4.4 with wget

cd ~/src/mainline/4.4

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400-generic_4.4.0-040400.201601101930_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-image-4.4.0-040400-generic_4.4.0-040400.201601101930_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400_4.4.0-040400.201601101930_all.deb

and install them with dpkg

sudo dpkg -i linux-headers-4.4*.deb linux-image-4.4*.deb

After installation, I updated the vmlinuz and initrd images on my EFI partition, rebooted and everything seemed to work alright. no need to update/reinstall nvidia drivers or wireless drivers, which i expected to. I may still need to reinstall CUDA though.

however, i did need to rebuild bcwc_pcie and reinstall the facetimehd camera module

if you need to remove these mainline kernels, simply sudo apt-get remove the corresponding packages

updating kernel with build

this is a bit more advanced, but worth it, I think. the readme included in the folder for the mainline kernel deb's describes the build process.

basically, the kernel source is downloaded via git and a tag is checked out. for ubuntu, there are several patches which are applied in order, the third of which contains the kernel config diffs. so I can easily match the configuration used by ubuntu developers in their build of the kernel and make minor modifications if i'd like.

so, start by cloning the repo

cd ~/src/mainline

# DOWNLOAD THE OFFICIAL TORVALDS TREE (instead of the below tree, the bandwidth is terrible)
git clone https://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack linux-4.4

# wait for it ... wait for it ... lulz

while you're waiting (repo > 1GB), download the build deps:

sudo apt-get install libncurses5-dev gcc make git exuberant-ctags bc libssl-dev
sudo apt-get install fakeroot kernel-wedge

also, download the patchfiles from the ubuntu mainline

wget http://kernel.ubuntu.com/.../*.patch

now checkout v4.4

cd linux-4.4
git tags --list | grep 4.4
git checkout v4.4

apply Ubuntu patches

patch -p1 < 0001*.patch
patch -p1 < 0002*.patch
patch -p1 < 0003*.patch

AUFS

download aufs4-standalone and aufs-util

git clone git@github.com:sfjro/aufs4-standalone.git ~/src/aufs4-standalone
git clone git@git.code.sf.net/p/aufs/aufs-util ~/src/aufs-util

TODO: finish documenting AUFS process for Docker

• apply AUFS patches
• build aufs-util
• install aufs-tools

update permissions

# fakeroot was failing until i updated these
chmod a+x debian/rules
chmod a+x debian/scripts/*
chmod a+x debian/scripts/misc/*

build

make clean
make mrproper
make oldconfig
make -j8 deb-pkg

install

sudo dpkg -i ~/src/mainline/linux-*-4.4.0*.deb

upkeep: update initramfs whenever apt-get makes DKMS changes. my wifi seemed to lose it's wireless-n capability, so I needed to sudo apt-get install bcmwl-kernel-source --reinstall. however, this didn't autogenerate an initramfs for my custom kernel, so i had to manually generate it with the following and then update my EFI. (on the other hand, this might be speculation on my part)

sudo update-initramfs -u -k all

update EFI: copy /boot/* images and make conf changes

ffmpeg

refer to FFMPEG docs

NOTE: you're really going to want to build these shared library dependencies in a location that's bundled together with FFMpeg and OBS. Otherwise, your OS won't hesitate to step on them when you update. Bye Bye lib-@#$%.so. No more OBS.

required packages:

Ran into problems building obs with this ffmpeg build, where make was complaining about "-fPIC" flags. I needed to add --enable-pic or --with-pic to each built dependency. or --enable-shared.

obs

refer to OBS docs

clone repo and checkout the latest release

git clone --recursive git@github.com:jp9000/obs-studio ~/src/obs-studio

Note: it helped to open a new terminal... I guess something didn't get set right with the ffmpeg install. cmake couldn't detect the ffmpeg version number until I opened a new terminal. I don't think setting --prefix on each of the dep installs really helped. instead, i think it was the fact that i had skipped pkg-config with ffmpeg

configure OBS

this always seems a bit harder on linux than osx. also, various streaming services likely have various requirements. the livecoding.tv doc is pretty good

configure RTMP multiplexer with live video effects

haha j/k j/k. one day.

python

So after i configured python in Linux Mint, somehow I ended up needing to sudo for every friggin pip command... So i really gotta get this right. Having that issue is really irritating to deal with after the fact.

As of now, I have ls -l $(which python) pointing to /usr/bin/python -> python2.7 and ls -l $(which python3) pointing to /usr/bin/python3 -> python3.4, with neither pip or pip3. So, clean install of both python2 and python3.

sudo apt-get install python-pip
sudo pip install virtualenv virtualenvwrapper

configuring virtualenvwrapper

to configure virtualenvwrapper add the following to your ~/.bash_profile or ~/.zprofile (or whatever)

export WORKON_HOME=$HOME/.virtualenv
export PROJECT_HOME=$HOME/dev/python
source /usr/local/bin/virtualenvwrapper.sh
# or load virtualenvwrapper_lazy for lazy loading

install pythons and pips:

# create a new virtaulenv
mkvirtualenv foo_env
# and thest
workon foo_env
pip install django # no sudo

strangely, i have a bunch of errors that show up concerning missing scripts that actually exist. i ran into this last time.

install system deps:

just going to build tf with system python. mostly because i dont' feel like learning how to config the equivalent of python-dev with virtualenv. does that mean i need to build python? and setup up libs in /usr/.../wherever? these are the things i don't actually want to spend the time learning. it'd be wonderful if i could find a python export to answer all these questions.

however, i'll be using tf with a virtualenv python, so i'll need to ensure these libs are set up there. another alternative is to build TF within a docker container. which just seems to be the way to go all around, for many, many reasons.

also, i could just download a pre-built TF docker image, but where's the fun in that? and besides, you can't [easily] add custom ops to TF if you're using a pre-built docker image. So no, no ops based on OpenCV api.

and HA!, i said 'easily'. maybe i should have said 'quickly' instead. although, that's a joke, if you're using GPU support in TF. the bazel build times are ridiculous with GPU!! i think the key here is to learn how to perform differential builds with bazel.

sudo apt-get install python-numpy swig python-dev

also, note: if performance really is an issue, building the deps for python numpy should probably boost performance significantly. but, so does using c++ instead of python. and in the end, your TF code will be written in c++ if it does anything crucial.

also, nvidia offers libs with GPU support for Lapack/BLAS, etc. Really, there is a ton of room for improvement on most apps with scientific computing and/or machine learning dependencies.

Postgres

download and config postgres with:

sudo apt-get install postgresql postgresql-server-dev-9.4

then, open a psql console with the postgres user:

sudo -u postgres psql postgres

now, run \passwd in the psql console to reset the password. finally, run sudo -u postgres createuser $PG_USERNAME to create a postgres user. answer no, yes, no to superuser?, create databases? and create roles?. If user is created non-interactively by this command, you might have to use 'psql' to grant the 'CREATE DATABASE` permission. In this case, open a psql prompt with the postgres user and run:

ALTER USER $PG_USERNAME WITH CREATEDB;

NodeJS

I needed to install NodeJS for execjs and uglifier from within a Rails project. I checked out this gist, which describes how to install:

git clone git@github.com:nodejs/node ~/src/node
git clone git@github.com:npm/npm ~/src/npm

mkdir ~/local
echo 'export PATH=$PATH:$HOME/local/bin' >> ~/.zsh/.zshrc # if it's not there already

cd ~/src/node
./configure --prefix=~/local
make -j8
make install

cd ~/src/npm
make -j8
make install

swift

why? because swift+swig is probably going to rock. i'm just saying.

ray wenderlich guide. swift.org repository list and dev snapshots.

but, i'm going to want to build swift-lang on linux, so that process is described on the main swift repo. also, need to build the swift package manager. and download some of the core libs.

swig will be needed if you want to do anything useful with swift. swig helps create interfaces to c++ from many different programming langs. it appears that someone has already tried to create a project to bridge swift to c++ libs using swiq, but sited some problems a bit over my head (non-re-entrant?) as to why it wouldn't work well.

it is possibly to extend swift with the functionality of c++ libs, but they need to be wrapped with c header files. i don't know enough about this domain to understand the best way to do this.

one of the reasons I like swift so much is because it's like a functional c. you can craft low-level, memory structing, bitcrunching apps and it feels fast. yet, you can easily employ your favorite functional programming patterns. and it easily interops with c if you need it.

docker

docker's own documentation is sufficient. mostly documenting this because, when using a custom kernel in Ubuntu, you can't apt-get a package for linux-image-extra, so ... no AUFS. also, i want all of my set up documentation to be centralized.

setup the docker ppa

echo "deb https://apt.dockerproject.org/repo ubuntu-wily main" > sudo tee -a /etc/apt/sources.list.d/docker.list
sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
sudo apt-get update
sudo apt-get purge lxc-docker
sudo apt-cache policy docker-engine # package docker-engine doesn't exist...

.... welllll looks like i have to patch the kernel and rebuild. fuck that right now.

weechat (linux)

for some reason, my osx weechat config doesn't work on linux. it just freaks out and loses the colors. THE COLORS!!

TODO: document weechat setup

NOTE: it makes me nervous running weechat with any priviledges at all, knowing that all the plugins rely on scripting languages and user-based configuration of string interpolation. euuugghhh. seriously, you should probably run weechat under another user or some shit, though ... that's not really going to help. run it on another laptop. that's what i always do. or within a vm/docker.

sometimes i wake up at night in a cold sweat and i could swear there's a weechat plugin vuln under the bed and i freak out and check it ... but there's never anything there.
