These are some useful notes to get Ubuntu installed in your surface go, as of Summer 2019.\nInstalling the kernel 1 2  git clone --depth 1 https://github.com/jakeday/linux-surface.git ~/linux-surface cp -a ~/linux-surface /media/\u0026lt;your usb\u0026gt;   1 2 3  cp -a /media/\u0026lt;your usb\u0026gt;/linux-surface ~/ cd ~/linux-surface/ sudo sh setup.sh   Booting ubuntu first Switch out of Windows S mode.\nBoot into the \u0026ldquo;Command Prompt\u0026rdquo;.\nFrom Windows go to \u0026ldquo;change advanced startup options\u0026rdquo; and select \u0026ldquo;restart now\u0026rdquo;.\nWhen it reboots, choose the \u0026ldquo;Troubleshoot\u0026rdquo; option, then choose the \u0026ldquo;Advanced options\u0026rdquo; option, and finally choose the \u0026ldquo;Command Prompt\u0026rdquo; option.\nAfter the device reboots, login to the command prompt and then you should see a terminal with X:\\windows\\system32\u0026gt;\nAt the prompt, check your UEFI entries:\n1  bcdedit /enum firmware   Copy UEFI entry of \u0026ldquo;Windows Boot Manager\u0026rdquo; to create a new entry for Ubuntu: bcdedit /copy {bootmgr} /d \u0026ldquo;Ubuntu\u0026rdquo;\nCopy the printed GUID number including the braces {} using Ctrl+C\nSet file path for the new Ubuntu entry. Replace {guid} with the returned GUID of the previous command (Ctrl+V). bcdedit /set {guid} path \\EFI\\ubuntu\\grubx64.efi\nSet Ubuntu as the first/ entry in the boot sequence. Again replace {guid} with the returned GUID of the copy command.\n1  bcdedit /set {fwbootmgr} displayorder {guid} /addfirst   Check your UEFI entries again: bcdedit /enum firmware You should see something like this:\n1 2 3 4 5 6 7 8 9 10  Firmware Boot Manager --------------------- identifier {fwbootmgr} displayorder {3510232e-f8eb-e811-95ce-9ecab3f9d1c4} {bootmgr} {2148799b-f8eb-e811-95ce-9ecab3f9d1c4} {312e8a67-c2f6-e811-95ce-3c1ab3f9d1de} {312e8a68-c2f6-e811-95ce-3c1ab3f9d1de} timeout 0   Make sure the GUID you copied is the first one listed in displayorder. Then type exit, turn off the PC and turn it back on. After this my surface go is automatically booting to the grub bootloader which lets me choose between Windows and Ubuntu but defaults to Ubuntu after ten seconds.\n","permalink":"/post/2019-05-01-surface-go/","tags":["linux","surface go","config"],"title":"Linux on the Microsoft Surface Go"},{"categories":null,"contents":"This is a short tutorial on connecting a zigbee device (an Aqara cube) to an MQTT server, so you can control your zigbee devices from the network.\nIf you're anything like me, you're probably a sucker for IoT devices. For a long time, I've been using WiFi-enabled lights, and Amazon dash buttons to control them. To keep these (cheap Chinese) internet enabled devices away from your network and their respective cloud services, you'll probably want to set up a dedicated network in your router (more on this on a future post, maybe). Another disadvantage of WiFi devices is that they're relatively power hungry.\nA popular alternative is using ZigBee for communication. It is a dedicated protocol similar to bluetooth (BLE), with lower power requirements and bitrate.\nTake the (super cute) aqara cube as an example. It is a small cube that detects rotation on all of its axes, and tapping events. Here's a video:\n  To connect to zigbee devices you will need a zigbee enabled gateway (a.k.a. hub), which connects to your WiFi network and your zigbee devices. Once again, this means adding an internet-enabled device to your home, and probably a couple of cloud services.\nAs an alternative, you can set up your own zigbee gateway, and control it to your home automation platform of choice (e.g. home assistant). We will cover how to set up a zigbee2mqtt gateway that is also connected to an MQTT server, so you can use MQTT to control your devices and get notifications.\nWhat you need:\n Aqara cube.
