Set up a new Pi in 10 minutes
The BEST thing to do is to copy the MicroSD from Carambola (marked with a black 'O'): open a terminal so we can watch the MicroSD /dev/sd{#} assignments sudo tail -f /var/log/syslog take the carambola MicroSD card out of the Pi and put it into an Anker hub (gets less hot than the small MicroSD sleeves - and it WILL get hot!) put another new MicroSD card into another Anker hub open another terminal dcfldd bs=4M if=/dev/sd{Letter of carambola} of=/dev/sd{Letter of new card} They will get HOT... I don't know how to make sure they don't get TOO hot yet... cross your fingers I guess... Drop the new card into the new Pi, boot, change /etc/hostname and reboot

Raspberry Pi Raspbian setup

Update gentoo kernel

OpenELEC multi-boot install
The easiest way is to add a new drive just for OpenElec and install OpenElec to it with the installer. But if you want to SHARE ONE DRIVE with other boots, DO NOT DO THAT :-) Do this instead: On an existing refind-booted system, set up two new ext4 partitions one about 2GB in size, labeled [SYSTEM], and marked as bootable the other with 10GB or more, labeled [STORAGE] prep the drives (no journal, ssd trim) download openelec and mount; there are a couple ways: get the img and install to a thumb get the img and mount (see below) Set up OE drives to mount in other OSes to /openelec-system and /openelec-storage /dev/disk/by-label/SYSTEM /openelec-system ext4 noatime 0 0 /dev/disk/by-label/STORAGE /openelec-storage ext4 noatime 0 0 copy target/KERNEL and target/SYSTEM to SYSTEM cp OpenELEC_img/target/KERNEL /openelec-system/ cp OpenELEC_img/target/SYSTEM /openelec-system/ set up UEFI boot subl /boot/efi/EFI/refind/refind.conf (and add this block) # MDM Trying this, from: http://openelec.tv/forum/64-installation/70783-how-to-efi-booting-openelec-on-new-pc-s-nuc-s # Only I had to change BOOT to SYSTEM. and quiet to debugging. menuentry OpenELEC { icon EFI/refind/icons/os_openelec.png volume SYSTEM ostype Linux loader KERNEL # options "boot=LABEL=SYSTEM disk=LABEL=STORAGE debugging" options "boot=LABEL=SYSTEM disk=LABEL=STORAGE quiet" } I THINK you need one or more of these too, not sure! cp target/boot/bootx64.efi /openelec-system/BOOT cp target/boot/bootx64.efi /boot/efi/EFI/ubuntu/ cp target/boot/bootx64.efi /boot/efi/EFI/ubuntu/

OpenELEC boot from thumb
NOTE: I have the image already on a white stick with red lettering... anyway... Get the latest dev version (stable didn't work for me although this may change) dd it onto a thumb reboot and select to boot to the thumb in BIOS when the boot: line comes up, type "live" to get run a live Kodi rather than run the crufty old installer

Windows 10 new setup
Grep for Windows Create sublime symbolic links to preferences, typically here: C:\Users\Michael\AppData\Roaming\Sublime Text 3\Packages\User etc.

Cloud and AWS tasks

AWS clone

create a snapshot of an instance
create an instance of a snapshot

Example...

   instances -> pa-jenkins-win-test -> right-click, Create Image -> 
       { 
           name: pa-jenkins-win-test, 
           AMI ID: ami-57cadc3d
       }
   This creates a new "AMI Image"- WARNING: The source machine will be rebooted!
   monitoring it, waiting for it to be ready... ready.  man that took a while.  
   Select AMI -> rightclick -> Launch...
       instance type: t2.medium (same as original; 2 vCPUs, 4GB mem)
       config: SELECT THE SAME SUBNET (us-east-1d) so on the same LAN and can ping each other; (all other defaults)
       storage: (default)
       tag instance: { name: "pa-jenkins-win-test-older" }
       security: select existing { "pa-shared immed_inno_group raleigh-windows-dev" } (as per Brad, previously - note that "raleigh" is no longer available) 
       LAUNCH
       ---
       select an existing key pair or create a new pair
           let's use the existing ones since this is a shared resource
           2014Dec25_air.pem (it's in my docs repo)
       ----
       monitor it, wait for it to be created...
       because it was cloned from a machine that had the password changed, you can't use the existing key to regenerate
       i didn't realize it was changed??
       anyway, it should be the exact same way to connect to test, but with a diff ip/hostname (*-older)
       yep.  switched IP to 172.30.3.208 and it's good to go!

Expand AWS storage

   stop instance
   in instance details, right-click the block device link (typically /dev/sd1)
   click the EBS ID
   snapshot the volume, wait for it to get to "complete"
   right-click snapshot, create volume
       use the same availability zone: us-east-1d
   on the volume created screen, click to show the volume
       vol-b88c3c45
   get the orig volume:
       vol-5af8f0a0
       https://console.aws.amazon.com/ec2/v2/home?region=us-east-1#Volumes:search=vol-5af8f0a0;sort=size
   type this into volume filter to see them both:
       vol-b88c3c45|vol-5af8f0a0
   make note of the attachment info for the old 30GB drive:
       Attachment information
       i-ad45941d (pa-jenkins-win-test):/dev/sda1 (attached)
   detach the volume!  holy cow.  
       i thought about restarting the instance and shutting it down first...
       but i think stopping it already did that!  MOVE ON    
   right click new volume, "attach volume"
       start typing instance name (pa-jenkins-win-test worked)
       CHANGE TEH SELECTED DRIVE NAME (xsdf or something) to the original!  /dev/sda1
       geez that's scary, wonder if it will work...
       YEP!!!  AW#ESOMENWESSSS##$$
   type "disk management", right-click the 30gb image, select Extend
   DONE!!!

Ubuntu set up networking
Install NetworkManager, as the wpagui UI sucks sudo apt-get install network-manager-gnome YOU MUST remove interfaces from /etc/network/interfaces so wpa gives them up to nm-applet add nm-applet to startup if needed - i don't think it is needed as it seems to start up automatically now - try rebooting first

Ubuntu install Sublime
Sublime editor seems way better than anything else out there on linux: sudo add-apt-repository ppa:webupd8team/sublime-text-3 sudo apt-get update sudo apt-get install sublime-text-installer git config --global core.editor "subl -n -w" # to use sublime with -n(ew window) and -w(ait for exit)

Ubuntu install Node.js
Install Node.js using the "Node.js Version Manager" nvm details find the latest nvm version curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh \| bash source ~/.profile nvm ls-remote nvm install ##### # (latest version, eg 5.8.0) MDM I don't need this do I? I'm not running express... npm install -g express # to set the package manager to use a globally shared location nvm alias default stable (update .bashrc to configure node on even non-interactive shells - see another for example) also: nvm use 4.2.1; node -v; nvm ls; nvm alias default 0.11.13; nvm use default also: You can create an .nvmrc file containing version number in the project root directory and it will default to that version

Ubuntu install Java

Install Oracle JDK 8 (9 is scheduled for release in 2016)

su -

apt-get install oracle-java8-set-default

- ctrl-D (back to user)

update-alternatives --config java # make note of path
update-alternatives --config javac # make note of path
sudo subl /etc/environment
JAVA_HOME="/usr/lib/jvm/java-8-oracle/jre/bin/java" # actually, use the path from above, of course
