How to download streaming video

Streaming just means a download that they don't want you to keep. But Chrome's developer tools make it easy to access what's really going on under the hood.

Open Developer Tools

From the page where you want to download some things, go into your chrome menu to open the developer tools. You can either:

1.  (On a mac): Command-option-J
2. (On a PC): Control-alt-J

Update:

This macro has been improved and moved into a new package: https://github.com/rdeits/AxisArrayVariables.jl

Original post:

We can define a macro to build up AxisArrays of JuMP variables:

This is a guide for local development of a Julia package in Julia 1.0 and above.

tl;dr: We use a new environment to ensure that our regular Julia environment is not affected.

Setting up a new environment

Navigate to ~/.julia/environments. This folder should contain the default environment. (I am currently working in Julia 1.0, so the environments folder contains the folder v1.0).

From the same folder, make a new project by running julia, then entering the Pkg repl by pressing ] from julia.

Upon entering the Pkg REPL, you should see a prompt like this:

Problem: 821`763=
Explanation:
The first number is 821, FN=[8,2,1]. The second number is 763, SN=[7,6,3]. Since FN [8,2,1] has 3 digits, SN [7,6,3] has 3 digits, thus the maximum number of digits is 3. In each subsequent step, we remove one number from the beginning of FN and one from the beginning of SN.
Length of FN is 3. FN=[8,2,1]. Length of SN is 3. SN=[7,6,3]. FN[3]=8. SN[3]=7. C[3]=0.  Since 8*7=56, 56%10=6, 56//10=5. Length of A is 1. Thus A=[6]. Since 5 is odd, we change the value of C. Since C[3]=0, C[2]=1. 
Length of FN is 2. FN=[2,1]. Length of SN is 2. SN=[6,3]. FN[2]=2. SN[2]=6. C[2]=1. Since 2*6=12, 12%10=2, 12//10=1. Length of A is 2. Thus A=[6,2]. Since 1 is odd, we change the value of C. Since C[2]=1, C[1]=0.
Length of FN is 1. FN=[1]. Length of SN is 1. SN=[3]. FN[1]=1. SN[1]=3. C[1]=0. Since 1*3=4, 4%10=4, 4//10=0. Length of A is 3. Thus A=[6,2,4]. Since 0 is even, we do not change  the value of C. Since C[1]=0, C[0]=0.
There are no more digits and C[0]=0. Thus the process is complete. Sin
