Some exercises from the Falsy Values workshops.
The good parts:
- HTTP server and client in same script
- Express cookies example
- Express routing example
- Express error handling
- Express middlewares example
- Simple HTTP proxy

This gist provides a simple JavaScript implementation of the non-standard WebKit method scrollIntoViewIfNeeded
that can be called on DOM elements.
Just use the code in index.js
in your app or website. You can see usage in the test page test.html
.
The parent element will only scroll if the element being called is out of the view. The boolean can force the element to be centered in the scrolling area.
L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns
Compress 1K bytes with Zippy ............. 3,000 ns = 3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns = 20 µs
SSD random read ........................ 150,000 ns = 150 µs
Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

# Usage: deinterleave_fastq.sh < interleaved.fastq f.fastq r.fastq [compress] | |

# Deinterleaves a FASTQ file of paired reads into two FASTQ | |
# files specified on the command line. Optionally GZip compresses the output | |
# FASTQ files using pigz if the 3rd command line argument is the word "compress" | |
# | |
# Can deinterleave 100 million paired reads (200 million total | |
# reads; a 43Gbyte file), in memory (/dev/shm), in 4m15s (255s) | |

I'm going to cover a simple, but effective, utility for managing state and transitions (aka workflow). We often need to store the state (status) of a model and it should only be in one state at a time.
