Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
Find bounding box dimensions either within or surrounding arbitrary containers
Available as a node package. To install use
$ npm install bbox
The following methods are available
BBox.create(x0, y0, x1, y1)
OR
BBox.create(width, height)
Creates a frozen bbox object with both position and dimensions. When using dimensions the box has undefined location but can still be used for its aspect ratio.
var BBox = require('bbox');
var fixed = BBox.create(1, 1, 4, 4);
// => {x0: 1, y0: 1, x1: 4, y1: 4, width: 3, height: 3}
var floating = BBox.create(2, 3);
// => {width: 2, height: 3, x0: undefined, y0: undefined, x1: undefined, y1: undefined}
BBox.fit(container, aspect)
Creates the largest box with the same aspect ratio as aspect
that will fit within container
. The box is centered within container
. Note container requires a fixed bbox but aspect may be fixed or floating.
var container = BBox.create(0, 0, 100, 100);
var aspect = BBox.create(250, 500);
BBox.fit(container, aspect);
// => {x0: 25, y0: 0, x1: 75, y1: 100, width: 50, height: 100}
BBox.surround(container, aspect)
Creates the smallest box with the same aspect ratio as aspect
that will surround container
. The box is centered around container
. Note container requires a fixed bbox but aspect may be fixed or floating.
var container = BBox.create(0, 0, 100, 100);
var aspect = BBox.create(250, 500);
BBox.surround(container, aspect);
// => {x0: 0, y0: -50, x1: 100, y1: 150, width: 100, height: 200}
