node.js - Optimal method(s) for installing select devDependencies using Heroku -

i curious know preferred method(s) installing select devdependencies using heroku. by default, heroku does not install devdependencies ; can enabled changing config: heroku config:set npm_config_production=false however, heroku docs recommend against this: since don’t want development dependencies in production builds, it’s preferable move dependencies need production builds (bower, grunt, gulp, etc) dependencies. i argue listing devdependencies in dependencies appears messy, package.json contains "duplicate" modules, eg: dependencies: { "eslint-config-airbnb": "14.1.0", "eslint-plugin-react": "6.10.3", }, devdependencies: { "eslint-config-airbnb": "14.1.0", "eslint-plugin-react": "6.10.3", } while pre/post build steps can taken , possible tell heroku install select devdependencies ?

canvas - How to draw a curve consisting of multiple line segments in a non-jagged way -

Image
i trying write program puts incoming usb data onto line graph. way have done drawing onto canvas bunch of straight lines connecting data points. problem resulting line not smooth, can see below: i tried using graphics context's lineto(x, y) method made worse. tried changing line cap , line join parameters didn't much. is there better way play "connect dots" javafx graphics context? perhaps bezier curves? if there is, please let me know. i ended going simplest solution problem, use boxblur effect: boxblur blur = new boxblur(); blur.setwidth(2); blur.setheight(2); blur.setiterations(1); gc.seteffect(blur); ... //don't forget remove effect before clearing gc.seteffect(null); gc.clearrect(0, 0, width, height); it's not exact solution, works fine purposes.

unity3d - Long chain / rope in unity2D -

i have created chain smaller chain segments , hingejoints. when there lot of segments chain gets elastic. , putting weight end breaks chain. adjusting mass of individual links improve link "strength". gives unnatural behaviour weight attached. are there other factors mass determine strength of hinge joints? any idea how create long chain less elastic (stronger).
