javascript - npm nested dependencies, why not imitate gem? -

-

i installing today sails.js, , see how install same package on , on again (dependencies of app dependency), why npm not use gem system? keep globally libraries , different versions, cool share same lib if have multiple projects on server , not installing on , on again same libs (i know workaround npm link seems not considered best practice).

dependency management difficult. npm strong opinionated not sharing packages , insisting every package have own node_modules folder. avoids lot of potential pitfalls can avoided. packages pretty small , better use tiny bit more disk space try chase down issues related dependency versioning.

also interesting, take note of when include node_modules in git. http://www.futurealoof.com/posts/nodemodules-in-git.html

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
