STM8 eForth: IR Remote Control for an RGBW LED Bulb

These days IR remote control is still the cheapest option for consumer electronics. I've long had the idea that Forth is ideal for scripting IR remote-controlled devices and I used the light bulb at my desk to learn how to do that with STM8 eForth. LED lamps of relatively high quality with a combination of white LED and RGB LEDs have a remarkable low price tag: the set below costs no more than a regular white LED lamp. In my experience service life is much better (maybe due to a switched mode power supply with constant DC voltage and µC PWM control). The option for occassional colorful illumination is a bonus.

This writeup covers analyzing light bulb IR remote control codes and using it with STM8 eForth . The code below also is a showcase for the expressive power of STM8 eForth on a cheap 8bit µC (e.g., STM8S103F3P6 w/ 8K Flash and 1K RAM).

Backup android app, data included, no root needed, with adb

Note: This gist may be outdated, thanks to all contributors in comments.

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !

VFIO Setup Guide

I play games regularly, and the sad reality is that it forces me to use Windows on my desktop. There's a Linux installation on there, but rebooting into it is such a massive interruption that I usually just move over to my laptop for programming. Working on a laptop leads to all sorts of ergonomic issues, and it felt like a massive waste to not develop on the desktop hardware I invested so much in. So after extensively researching what the VFIO community has been doing, I've deleted my Windows installation and moved all my gaming into a virtual machine on a Linux host.

Normally VMs are too slow for gaming, but thanks to a feature called VFIO you can run games at near-native performance by passing graphics cards and USB controllers directly to a virtual machine. The only requirement is that your board supports IOMMU, which most modern systems have. In this guide I'll wal

With the release of Vivaldi 2.2, this page is now obsolete and unmaintained. Widevine is fetched automatically on post install of our official packages. The information below and the script are left for historical reasons but will not be updated.

If you are using something newer than Vivaldi 2.2, you should not be using this script as there is simply no need. Any need you think you have for it would be a bug IMHO and thus should be logged in a bug report. Before you do so however, you should also checkout the Vivaldi help page on Widevine, on Linux

Summary

A bunch of people asked how they could use this script with pure Chromium on Ubuntu. The following is a quick guide. Though I still suggest you at least try Vivaldi. Who knows, you might like it. Worried about proprietary componants? Remember that libwidevinecdm.so is a b

You do not need a separate /boot partition unless you have an LVM setup (used in dm-crypt setups).

Run ubiquity -b to open the installer with the option of skipping grub installation (since we're using systemd-boot).

When you get to the screen "Ubuntu has finished installation" choose Continue testing.

Open a Terminal.

Chroot into the new system.
