An Aesthetic Comparison of Human-Readable
Hashing Functions

The following compares the output of several creative hash functions designed for human readability.

sha1's are merely used as arbitrary, longer, distributed input values.

Experimenting with pitch detection and spectral estimators

See the question and discussion on StackOverflow: How to get the fundamental frequency using Harmonic Product Spectrum?.

We’re trying to estimate the fundamental frequency of a voiced A4 note (440 Hz). (See the question for link to audio clip.)

Harmonic product spectrum

Result: full data, 0 to 2 KHz

This is an attempt to make assert more friendly by including more details in the assertion error.

• show the result of the assertion expression
• show local variable values used in assertion form

In other words, this should make assertion errors easier to reason about:

AssertionError Assert failed: Should be equal

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

LazerPanther

Semantic history command for iTerm2 and Neovim.

In iTerm's Preferences > Profiles > Default > Advanced > Semantic History, choose Run command... and enter /your/path/to/iterm_open_with \5 \1 \2.
