privacy - How to start vim in "private mode" -

-

modern browsers have feature called "private mode" or "incognito mode". trying same thing vim, i.e. run in way no traces of activities left behind. way able e.g. use vim open file containing sensitive information stored in encrypted volume without having worry information leaked.

here's have done far:

alias vim_private="vim -i none --cmd 'set noswapfile' --cmd 'set nobackup'"

i have in .bashrc. rationale above:

  • -i none no filenames or register contents leaked through .viminfo
  • --cmd 'set noswapfile' prevent creation swap file
  • --cmd 'set nobackup' no backup files

is there else i'm missing? there other ways vim leak information?

your settings fine. i'm not sure whether plugins loaded when invoke vim vi, several plugins (that e.g. provide mru functionality) store information (usually in ~/.vim... files), too. load can avoided through --noplugin.

also, paranoid, $viminit, :set exrc, , :set modeline can lead vimscript code being executed; (re-)enable privacy-relevant options.

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
