the twelve-factor app manifesto says web applications "... have clean contract underlying operating system, offering maximum portability between execution environments" [emphasis added me] but it says : twelve-factor apps not rely on implicit existence of system tools. examples include shelling out imagemagick or curl . while these tools may exist on many or systems, there no guarantee exist on systems app may run in future, or whether version found on future system compatible app. if app needs shell out system tool, tool should vendored app. and have earlier defined "vendored app" as: scoped directory containing app (known “vendoring” or “bundling”). how should done, when (on linux @ least) native 64-bit executables not run in 32-bit environments, example - let alone on other operating systems? or there better way of handling portability issue? in opinion, it shouldn't done @ all . because: if native executable...

got selenium ide script recorded , being played using selenium server in -htmlsuite mode.it supposed put type user name, password , domain click login. after logging in, @ 1 corner, should show username @ domain. have verifytext this. when ran script in firefox, working correctly, in ie, keeps failing - giving me error message actual value 'username @ domain' did not match 'username @ domain'. tried assert , same thing. bug in selenium or something? you should try using waitfortext , waitforelementpresent or waitfortextpresent commands, depending on specific need. the reason being usually, when text created script on/after page load, selenium doesn't know - can't possibly wait every script finish, because there's lot of scripts never finish , run forever. therefore, need wait specific elements appear before can assert them.

i developed facebook-like chat in php , javascript. it's plugin forum software. i'm using (short) polling receive new messages, i'd try better, sockets. what recommend kind of chat (available on every site, private chat, group chat..) : websockets, node.js socket.io, ejabberd... from personal experience there no socket library available php. 1 wants have socket library have fallback mechanisms if native socket support not available. 2 suggestions me : switch node.js + socket.io solution, discard php. have nodejs + socket.io chat system running separate server along php. put haproxy in front of webserver. divert socket request node.js , other request php. in way able use goodies of both node.js , php. i had similar situation , using option 2 :).
