| Access Guest Machine Localhost: | |
| 1. In VM settings under 'Network', change 'Attached to' from 'NAT' to | |
| 'Bridged Adapter'. | |
| 2. Find IP address of VM and use it to access. | |
| Boot from USB: | |
| 1. Set SoC's OTP (One Time Programmable) memory for USB boot by executing: | |
| echo program_usb_boot_mode=1 | sudo tee -a /boot/config.txt | |
| 2. After reboot you can check OTP has been programmed with: | |
| vcgencmd otp_dump | grep 17 | |

| Build EDuke32: | |
| 1. Install dependencies: |
| Add Linux Boot Option With bcdedit | |
| 1. bcdedit /create /d "Linux" /application BOOTSECTOR | |
| 2. bcdedit will return an ID for this entry (for example something like - | |
| {de50478b-bb21-11e1-837e-001d72ceba3a}) that we will call {Linux-ID} below: | |
| bcdedit /set {Linux-ID} device partition=C: | |
| bcdedit /set {Linux-ID} path \boot-loader.bin | |
| bcdedit /displayorder {FreeBSD_ID} /addlast | |
| * Note: Get the BOOTSECTOR file from Linux using something like | |
| dd if=/dev/sda3 of=/mnt/share/linux.bin bs=512 count=1 |
| Antenna Length: | |
| 1/4th length [in m] = 74948114.5 / f [frequency in Hz] | |
| 1/4th length [in cm] = 7494.81145 / f [frequency in MHz] | |
| Radio Frequency Spectrum Ranges: | |
| VLF: 3kHz-30kHz 100Km-10Km | |

| Linux - Post Install | |
| Reduce system swappiness (for SSD based systems). Add the following line to | |
| '/etc/sysctl.conf': | |
| vm.swappiness=10 | |
| Use a ramdisk to store temporary data if you have enough RAM (for SSD based | |
| systems). Add following lines to '/etc/fstab': |
| { | |
| // Enforcing | |
| "bitwise" : true, // true: Prohibit bitwise operators (&, |, ^, etc.) | |
| "camelcase" : false, // true: <Deprecated> Identifiers must be in camelCase | |
| "curly" : false, // true: Require {} for every new block or scope | |
| "eqeqeq" : true, // true: Require triple equals (===) for comparison | |
| "esversion" : 3, // {int}: Specify ECMAScript version to which code must adhere: 3 (old browsers, 5, 6) | |
| "forin" : true, // true: Require filtering for..in loops with obj.hasOwnProperty() | |
| "freeze" : true, // true: Prohibits overwriting prototypes of native objects such as Array, Date and so on | |
| "funcscope" : false, // true: Suppress warnings about declaring variables inside blocks while accessing later from outside e.g. 'function foo() { var bar = 0; }; bar++;' |
Setting up Dump1090, PiAware, FlightRadar24Feed, PlaneFinder Client, AdsbExchange Feeder, AirNav RadarBox Feeder & OpenSky Network Feeder
Fix dump1090-mutability service not working by default, due to missing udev rules:
sudo wget -O /etc/udev/rules.d/rtl-sdr.rules "https://raw.githubusercontent.com/osmocom/rtl-sdr/master/rtl-sdr.rules"
sudo reboot
