! MIGRATION IN PROGRESS: config distro machine migration
|-
|Start to revamp config from [machine]/[distro] to [distro]/[machine] to match scripts.  It's not hard even though it's dangerous.  You can do each machine separately from others.  Get on it!
 # DO THIS ALL IN ONE SESSION, do not log out
 cd development/config
 mkdir -p distro # prolly not needed
 git mv machine/distro distro/machine
 setup_stow.sh # repeat until it doesn't fail; check each failure to make sure it is a symlink, and simply rm them as you go

! Upgrade Ubuntu
|-
| To update ubuntu from an i3 terminal:
 su -
 apt-get update        # Fetches the list of available updates
 apt-get upgrade       # Strictly upgrades the current package
 apt-get dist-upgrade  # Installs updates (new major versions, i think)
 update-manager -d    # kick off the update manager to migrate to new release when available
Or just call the script that does the same thing:
 upgrade_ubuntu
I'm currently migrating everything to 16.04 Xenial Xerus.

! Test your drives - DO THIS OFTEN
|-
| Look at available tests:
 smartctl -c /dev/sdf # to peek at available tests and how long they typically take to run
Short test:
 smartctl -t short /dev/sdf
 watch -n 3 smartctl -l selftest /dev/sdf # you won't see anything until it finishes, takes about 1 minute
Long test:
 smartctl -t long /dev/sdf
 watch -n 3 smartctl -l selftest /dev/sdf # takes about 5 minutes

! Mount an IMG file
|-
| You have to peek at the file with fdisk:
 fdisk -lu /home/m/bitpost/download/torrents/OpenELEC-Generic.x86_64-5.0.8-efi.img
From that you can tell the "units" and "Start" offsets:
 Device                                                                    Start    End Sectors  Size Type
 /home/m/bitpost/download/torrents/OpenELEC-Generic.x86_64-5.0.8-efi.img1   2048 526336  524289  256M Microsoft basic data
 /home/m/bitpost/download/torrents/OpenELEC-Generic.x86_64-5.0.8-efi.img2 528384 593920   65537   32M Linux filesystem
From there you can mount with a little math.  Multiply the units by Start to get offset (512x2048=1048576), and use it to mount that partition:
 mount -t auto -o loop,offset=1048576 /home/m/bitpost/download/torrents/OpenELEC-Generic.x86_64-5.0.8-efi.img /media/m/iso

! Windows symbolic links
|-
| Windows symlinks - needed for config files, svn overlay, etc.

I'm setting up hard links from sublime install folder to shared config settings:
 mklink [/H /D /J] link_path Target_file/folder_path
We had to use a soft link, hard won't go across drives.  And you have to run the cmd window as admin.  Don't specify type, and it will create a soft file link:
 mklink "C:\Users\Michael\AppData\Roaming\Sublime Text 3\Packages\User\Default (Windows).sublime-keymap" "D:\Michael's Data\development\config\common\home\m\.config\sublime-text-3\Packages\User\Default (Windows).sublime-keymap"
 mklink "C:\Users\Michael\AppData\Roaming\Sublime Text 3\Packages\User\Preferences.sublime-settings" "D:\Michael's Data\development\config\common\home\m\.config\sublime-text-3\Packages\User\Preferences.sublime-settings"
Here is another example, setting up a link in an SVN repo folder to point to a git-controlled folder on another drive.  SVN is OK with this, cool.
 (open ADMIN cmd prompt)
 cd C:\CODE\QA\ContinuousIntegration\Trunk
 mklink /J scripts "D:\Michael's Data\development\power_analytics\scripts"
   Junction created for scripts <<===>> D:\Michael's Data\development\power_analytics\scripts

! Windows route traffic to avoid VPN
|-
| You can use "route" to assign paths to specific traffic.
So bitpost.com requests go through eth0 instead of VPN, eg...
 C:\WINDOWS\system32>route add 174.109.14.112 192.168.50.1
Note that you can do this with [route] in linux too, syntax is a bit diff.

|Type cmd in start search box and right-click on the cmd shortcut which appears in the results. Select Run CMD as administrator.
Next, in the command prompt, type wmic and hit Enter.
Now try to maximize it!
Close it and again open it. It will open as a maximized window!
You may have to ensure that the Quick Edit Mode in the Options tab is checked.

! Oontz turn on dual pairing
|-
| Turn them both on.  One should be paired with your phone, the other should be flashing blue, trying to connect.

On the Play Control Speaker (speaker with solid Blue Light) press and hold down the Play/Pause button for 5 seconds until the flashing White Light appears and the speaker says “Dual Pairing”. - The Play Control Speaker will then connect to the second speaker.

There is NO WAY you can guess this.  You'll be back here to re-learn...

|'''AMD'''
Radeon driver sucks, won't go over 1080p; and Dune (AMD chipset) overscans so you can't see the edge.
The only fix I found was to use xrandr.  It kinda sucks though bc it's a resize solution that blurs all pixels.  Cest la vie.
 xrandr --output HDMI-0 --set underscan on
 xrandr --output HDMI-0 --set "underscan hborder" 40 --set "underscan vborder" 22

For 4k video on an nvdia chipset (like wimpy), first get Ubuntu to use nvidia's driver:
* Go to System Settings-> Software & Updates
* Select the Additional Drivers tab
* Select the tested, proprietary NVIDIA binary driver
* REBOOT - the nvidia driver works at the kernel level so you won't be able to just restart X.  fools
* WHY does ubuntu make you do all this?

! Creating a new ssh key pair for no-password access to a remote system
|-
| Say you've got a new machine with user [m] and you want to connect to it, do this:
* install sshd, make sure it's running
* get on the new machine - ssh to the new machine by typing the password if you don't have direct access
* $ scp m@tdm:.ssh/id_rsa .ssh/
* $ scp m@tdm:.ssh/authorized_keys .ssh/

 wow I just had serious issues with basic ssh usage, so i'll put a summary on the wiki
    basically most misunderstandings stem from describing these two:
        client: machine that is trying to ssh into the server
        server: machine that the client user wants to get to
    most poor sots are just sitting on the client
    and they create a pair and push their public key to the server
    but in my case, more often, i want to create a pair on the server
    and push the private key to the multiple places i need to connect FROM
    when doing that, you have to push the public key into the server's authorized_keys
    and configure the client to juggle multiple private keys
 
        create a key pair:
            ssh suser@server
            ssh-keygen
                use defaults
                will create:
                    .ssh/id_rsa (private key)
                    .ssh/id_rsa.pub (public key)
 
        put the public key in place:
            cd .ssh
            cat id_rsa.pub >>authorized_keys
 
        put the private key on the client and configure:
            scp id_rsa cuser@client:.ssh/id_rsa_server
            ssh cuser@client
            em .ssh/config

* HARDWARE: 
** Plug keyboard/mouse hub into TOP USB SLOT in back or BIOS won't recognize it
** Make sure you plug Vive usb into a USB 3.0 slot
* ON BOOT:
** REMOVE USB KVM or the keyboard won't work - most of the time that's ok because we let it go through
** IF you boot into ubuntu, the USB hub didn't seem to work, i had to plug right into mobo

* had to install from iso after windows update got stuck FUCK OFF
 	it TOTALLY WENT ON A DIET
 	my 148GB drive was only using 34GB AFTER the install and cleanup
 		WAY better than before
 took the time to move EVERYTHING I COULD to fatboy
 	steam base install, plus games
 	origin base install, plus games
 	visual studio ce, plus mobile, c++, game dev
 		but it sucked up 36GB on "system drive", assholes
 		they dump android stuff, ios stuff, all this bullshit there
 		cest la vie
 installing:
 	chrome (like pulling teeth to get it set as default)
 	steam, games
 	origin, games
 	vs ce 2017 edition w/xamarin,c++,games,unity

''' Fixing boot '''
Windows Updates tend to clobber the EFI boot setup.

THen you have to set BIOS to boot with "UEFI+Legacy", and put the UEFI "USB" drive first in front of the "Windows Boot Manager" one.

THen reboot, you should get grub.

Go into Ubuntu and reinstall refind.

Boot back into bios, and set back to UEFI boot.  Leave the USB drive first.  Reboot and yhou should get refind again.  FU Bill.
''' Install Ubuntu '''
To originally install ubuntu, I had to add [... --- nomodeset] to the boot line in the grub booter.

Then I had to use a desktop 1080p monitor - the 4k Sony would not come up for some reason.

The Seiki is working fine now, go figure.

|You can override settings in /flash/config.txt; here's how, from [http://wiki.openelec.tv/index.php/Config.txt here]:
 mount -o remount,rw /flash
 nano /flash/config.txt
 # Make your changes, then ctrl+x to save.
 mount -o remount,ro /flash
 reboot

10% gaming machine, has steam, low end half-height video card that works fine for Risk of Rain etc.
It has a mid-range video card, enough to drive 1080p x 2 for development.
This used to be the primary Kodi box up until 10/2015, should still be current.
It has the same high-end i5 or i7 of other 2015 boxes, fast.

Install all hardware-specific packages in one shot:
 sudo apt-get install firmware-b43-installer xserver-xorg-input-mtrack
Post-install MUST-DOs:
* broadcom "b43" wifi driver: 
 sudo apt-get install firmware-b43-installer
 (reboot)
* synaptic driver (for trackpad)
 sudo apt-get install xserver-xorg-input-mtrack
 # use synclient to determine what works best

 synclient PalmDetect=1 # temporarily change settings
 # save what you like, here:

'''Windows 10'''
** Upgraded existing Windows 8.1
** Hack the INF file of the nvidia driver to get it to install - runs PERFECTLY 
*** TODO add details
** Add bluetooth stack - or not - i think i ended up back at the default Windows
** keyboard driver to get function key working: /spiceflow/softraid/software/OS/windows/macbook_windows10_drivers/AppleKeyboardInstaller64.exe

Then one day... it just stopped booting... Ten-Plus says the main board has a bad power circuit or something... sad day, MOVE ON.

|Follow the ubuntu install.

We also use a StarTech AC600 ac wifi adapter.  The chipset is specified [http://www.startech.com/Networking-IO/Wireless/usb-2-ac1200-wireless-network-adapter~USB433WACDB here].  It's a Realtek - RTL8811AU.  It is not supported with the vanilla 15.04 kernel, but it's easy to build a module from sources available on github:
 sudo apt-get update
 sudo apt-get install linux-headers-generic build-essential git
 git clone https://github.com/gnab/rtl8812au.git
 cd ~/rtl8812au
 make
 sudo make install
 sudo modprobe 8812au
Then, run NetworkManager and nm-applet, and as soon as you plug the USB dongle in and remove the wired connection, you'll get a running wifi applet, YES.

We also want to drive the crappy Seiki at 4K.  A 4k mode shows up in our X probe, but ubuntu is not picking it...... yet...
