android - What drains the battery more: A longliving Service that does not do much or a many shortlived IntentServices -

-

i designing application collect different data lot of sensors , store them in db, continuously. sensors using google play's fused location provider , activity detection. (there ui well, ui barely launched, happening in background)

i got 2 different ways this:

1) start longliving service

so start long-living service (with sticky flag), run in background. service register periodic location , activity updates , - in between updates - nothing.

pros: app initialized once

cons: service running 24x7

2) register pendingintent , use shortlived intentservice

now google play's location provider support registration of pendingintent instead of callback [see here](https://developers.google.com/android/reference/com/google/android/gms/location/fusedlocationproviderapi#requestlocationupdates(com.google.android.gms.common.api.googleapiclient%2c%20com.google.android.gms.location.locationrequest%2c%20android.app.pendingintent) recommended background tasks.

pros: app can 'shut down' between sensor events

cons: each intentservice might re-start app if shut down inbetween, has quite overhead (initialize db, read shared prefs, initialize classes, ...)

so question is: is still recommended use many short lived intentservices kind of app? haven't done measurements yet, worried, each intentservice (and launched quite often), re-starts app, end spending more cpu time on initialization, etc. having long-lived service lying dormant.

anybody has experience this?

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
