STM32F407G-DISC1/STM32F4DISCOVERY DFU mode
  1. Take every jumper off except JP1. Take both jumpers off CN3. Take the jumpers JP2 and JP3 off from the bottom of the board.
  2. Put a jumper between BOOT0 and VDD.
  3. Connect with a wire PA9 to 5V.
  4. Connect the device using the micro USB port, not the mini-USB port.
  5. sudo dfu-util -d 0483:df11 -a 0 -s 0x08000000 -D build/Example_Project.bin
  6. Unplug the device.
  7. Disconnect the BOOT0 jumper.
  8. Plug the device in.

.aupreset to .fxp.
/*
From: https://forum.juce.com/t/script-to-convert-aupreset-to-fxp/7919
Author: https://forum.juce.com/u/yairadix
I made a small Python script to convert .aupreset files to .fxp format (VST presets).
Hopefully others may find it useful too.
Our use case for it was creating our factory presets for SurferEQ once in Logic and then converting them to other formats.
This script could be easily adapted to convert the other way around. (it uses the Construct library to describe the fxb format declaratively for both parsing and building)

Polycom CX300 Linux HID

Polycom CX300 under Linux

The Polycom CX300 and similar Plantronics Calisto 540 (P540-M), snom UC600 are originally optimized for Microsoft Lync (Skype for Business) for Windows and Mac but can also be used with Linux. It shows up as a USB audio playback and recording device (this part works immediately out of the box) plus some USB HID (this needs to be made work; see below).

Headless A2DP Audio Streaming on Raspbian Stretch

About

This gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

Motivation

A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:

  • Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
  • Simple - This solution has few dependencies, readily available packages and minimal configuration.
  • Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43

Getting the fingerprint reader of a Thinkpad x240 to work under Ubuntu 14.04

lsusb lists the fingerprint reader in the x240 as follows:

Bus 002 Device 003: ID 138a:0017 Validity Sensors, Inc.

There exists experimental driver support for this in a fork of libfprint for vfs5011 sensors, however you'll need to compile the driver yourself. To get the fingerprint sensor to work for lightdm login, su etc, follow these steps.

  1. Install fingerprint-gui:

    sudo add-apt-repository ppa:fingerprint/fingerprint-gui

L2TP/IPsec（AndroidやiPhoneからのVPN接続）を経路を用意すべくVPSにL2TP/IPsecサーバを設置するとき、ネットにある情報だとなかなかつながらないから、標準環境としてAWSのCentOS 6.3 x86_64 Release Media(ami-3fe8603e)の起動直後から最短距離で設定する方法をまとめた。

CentOS 6でとにかくL2TP/IPsecサーバ

  • AWSでEC2のインスタンスを借りる
  • 今回は東京リージョンのCentOS 6.3 x86_64 Release MediaのAIM(ami-3fe8603e)でインスタンスを建てる
  • Security Group: L2TP/IPsec（Inbound 22/TCP: SSH, 500/UDP: ISAKMP, 1701/UDP: L2TP, 4500/UDP: IPSec NAT Traversal）を許可
  • ec2-54-249-173-214.ap-northeast-1.compute.amazonaws.com（グローバルIPアドレス：54.249.173.214）にrootでログイン
