Note: Since this seems to be helpful to some people, I formatted it to improve readability of the original. Also, note that this is from 2016, many things may have changed, and I don't use macOS anymore, so I probably can't help in case of questions, but maybe someone else can.

Mac Network Commands Cheat Sheet

After writing up the presentation for MacSysAdmin in Sweden, I decided to go ahead and throw these into a quick cheat sheet for anyone who’d like to have them all in one place. Good luck out there, and s

Converting mkv to mp4 with `ffmpeg`

Essentially just copy the existing video and audio stream as is into a new container, no funny business!

The easiest way to "convert" MKV to MP4, is to copy the existing video and audio streams and place them into a new container. This avoids any encoding task and hence no quality will be lost, it is also a fairly quick process and requires very little CPU power. The main factor is disk read/write speed.

With ffmpeg this can be achieved with -c copy. Older examples may use -vcodec copy -acodec copy which does the same thing.

These examples assume ffmpeg is in your PATH. If not just substitute with the full path to your ffmpeg binary.

A Hugo Survival Guide

Hugo is a static site generator: it takes some plain-text content, marries it to a bunch of HTML templates, and produces a set of complete, static HTML pages that can be served by any generic, stand-alone web server. Simple.

Or maybe not. Hugo does a lot of things automatically, relying on conventions and implicit rules, rather than on explicit configuration. For example, it tries to match each piece of content with the most

General vocab

CNN: convolutional neural net: replace linear layers with convolutions
GAN: generator and discriminator training in tandem
SGD: stochastic gradient descent
Supervised: training data is labeled (MNIST 0-9 digit labels)
Unsupervised: training data is unlabeled (DCGAN bedrooms are just bedrooms)
Parameters: learned weights and biases within NN layers
