petermolnar aaronpk, or anyone else with deep GPS-related service knowledge: is anyone aware of a relatively easy (either api calls or offline database) that could give me altitude information for lat/lon positions?
#
Zegnat Did you check out https://developers.google.com/maps/documentation/javascript/elevation ?
#
mindB Mapquest has a fairly simple elevation api, too, if I remember correctly.

tantek whoa I just got a "503 Service Unavailable / No server is available to handle this request." from somewhere in the middle of my admin page
#
tantek and it's not obvious to me where its coming from. huh
#
tantek like this is injected into the middle of my markup, not by any of my code (I have no code that explicitly generates this) "<html><body><h1>503 Service Unavailable</h1> No server is available to handle this request.</body></html>""
#
tantek this will take some interesting PHP debugging
#
tantek and I have text that my code generated both before and after that
#
tantek it was intermittent apparently, and is gone now
#
tantek like is there a PHP function that can error out by writing that to the output buffer?!?
#
tantek what is particularly odd is that at that point in my code, there shouldn't be anything that is making an HTTP request.
#
aaronpk that’s happened to me when there have been certain syntax errors
#
aaronpk i don’t know exactly what kind, but sometimes it’s so bad that php doesn’t even get a chance to output an error message
#
tantek syntax errors in what?
#
aaronpk in my php code
#
tantek ok so it is PHP that is doing it (the markup looked suspiciously like a PHP default bail / error message)
#
aaronpk well that error message and html is coming from the web server itself
#
aaronpk because it can’t run the php code for some reason
#
tantek like another PHP file perhaps?
#
tantek like it just had trouble loading another .php file from the current one?
#
aaronpk usually there’s an html file on disk that the web server uses to serve the message when it encounters that error
#
tantek yeah I'm just wondering what in code triggered it
#
tantek in *my code
#
aaronpk could also be nothing to do with your code. that error also means there are no backend processes to handle the request, such as when the server gets too many requests and all the php processes are busy
#
tantek ah ok
#
tantek yay shared server!
#
tantek (could be nothing to do with my "server" as it were)
#
tantek (since it's shared)
#
tantek oh well, I've made a note of the conditions in case it happens again. I wonder if this is an excuse to "compile" your PHP for an "app" into a single file ;)
#
aaronpk that wouldn’t really make a difference
#
aaronpk if you want to start thinking about that kind of optimization, then just use APC
#
petermolnar APC? above php5.6 you have the built-in optimizer
#
aaronpk ooh? i have not been paying attention to the 5.6+ stuff
#
petermolnar you should, php7 is indeed _much_ faster
#
petermolnar 5.5
#
petermolnar not 5.6: https://en.wikipedia.org/wiki/List_of_PHP_accelerators#Zend_Opcache_.28ex._Zend_Optimizer.2B.29
#
petermolnar Zend Opcache
#
aaronpk is it turned on by default in 5.5 or just shipped with 5.5?
KevinMarks joined the channel
#
petermolnar shipped w/ 5.5, that's why I had a hard time trying to use apc
#
petermolnar but unlike apc, opcache doesn't have a user-entry part, it's essentially bytecode cache only, APCu is there for the memcache-like user-data option
#
petermolnar http://php.net/manual/en/book.opcache.php
#
petermolnar there is PECL version for 5.2->5.4
#
petermolnar from 5.5, it's bundled
