Created May 3, 2020 — forked from Jorijn/borgbackup.sh
This is the script I use to backup my macbook to a borgbackup repository. It should be a drop-in script and suit most users just fine, but I do recommend looking at the values and making them fit for your specific situation.

# Setting this, so the repo does not need to be given on the commandline:

# Setting this, so you won't be asked for your repository passphrase:

function info () { echo -e "\n"`date` $@"\n" >&2; }

# Compiles a Python package into a zip deployable on AWS Lambda
#
# - Builds Python dependencies into the package, using a Docker image to correctly build native extensions
# - Strip shared object files for smaller size ca. 20% reduction
# - Remove .py and use .pyc's = faster lambda and ca. 20% reduction
# - Remove tests, info (minor reduction, but why not)
# - Remove packages that will be available in AWS lambda env anyway (boto et al) ca. 50mb (uncompressed) reduction
# - Able to be used with the terraform-aws-lambda module

GCC compiler optimization for ARM-based systems

2017-03-03 fm4dd

The gcc compiler can optimize code by taking advantage of CPU specific features. Especially for ARM CPU's, this can have impact on application performance. ARM CPU's, even under the same architecture, could be implemented with different versions of floating point units (FPU). Utilizing full FPU potential improves performance of heavier operating systems such as full Linux distributions.

-mcpu, -march: Defining the CPU type and architecture

These flags can both be used to set the CPU type. Setting one or the other is sufficient.

Live stream Xiaomi Ants Smart Camera via FFMPEG

This assumes you have a Xiaomi Ants Smart Camera that still has the open RTSP enabled. I think newer firmware might remove this capability. If you Google enough you can find instructions on how to downgrade.

FFMPEG

FFMPEG is where most of the magic happens. I use OSX and as such am a fan of using Homebrew to install free software. Here is my ffmpeg install command:

brew install ffmpeg --with-faac --with-fdk-aac --with-ffplay --with-fontconfig --with-freetype --with-frei0r --with-libass --with-libbluray --with-libcaca --with-libquvi --with-libsoxr --with-libssh --with-libvidstab --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-openssl --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools --with-webp --with-x265
