i'm working on php web app deployed amazon web services. have load balancers in front of auto-scaled application servers. the problem we're facing @ moment handling sessions. while sticky sessions reasonable solution, we'd persist sessions quite long time (weeks ideally). impair performance of load balancer on time. also, using auto-scaling mean that, time time, we'll remove server , lose of active sessions on it. of course, use common database store sessions, i'm bit concerned performance if every request requires round-trip db. i'd grateful if suggest solutions have worked you, or ideas try. thanks in advance help, ross i use custom session solution sessions stored in datatabase. that way webservers have access same session store , can decide self how long session should kept. you either build works php normal sessions or stand alone class handle them. i did similar share session between asp , asp.net on different serves , works. if

while doesn't tail call optimization ever added common optimization technique, after sun bought, wouldn't technically possible let languages running on vm decide if compiler emits tailcall instructions in byte code? e. g. java, groovy can decide not use instruction, while more functional languages scala or clojure can emit , hotspot vm optimize ones marked tailcall ? yes, technically possible -- in fact there experimental patch arnold schwaighofer openjdk that, although isn't easy apply patch , build, isn't kept date @ present. an explicit tail call instruction has advantages on transparent optimisation of function calls in tail position jvm, jvm can verify have specified tail call see tail call blog post john rose explanation of of verification can done. i think future of jvm not java, , hope time , talent pushes tail calls jvm forward.

$idarray = array(1,2,3,4); can write line in html? <form method='post' action='{$_server['php_self']}?arr={$idarray}'> or should write: <form method='post' action='{$_server['php_self']}?arr[]={$idarray}'> how passed? how should handle in called page? thanks !! if want pass array parameter, have add parameter each element. query string become: ?arr[]=1&arr[]=2&arr[]=3&arr[]=4 as others have written, can serialize , unserialize array. but have send data client again? looks need way persist data between requests . in case, better imo use sessions (docs) . more secure otherwise client modify data.

i've heard it's not possible, figured i'd ask here , definitive answer. there way use team foundation server 2010 sdk programatically create new project in collection? so far, i've seen use method of scripting vs 2010 ide: http://blogs.msdn.com/b/granth/archive/2009/09/25/scripting-team-project-creation-in-tfs2010.aspx . ugly. i'm keeping fingers crossed there's better way. ideas? you can use instead of command line: string log = @"c:\builds\tfslog.txt"; string settingsfilepath = @"c:\teamprojects\teamprojectsettings.xml"; var batchteamprojectcreator = new batchteamprojectcreator(); var succes = batchteamprojectcreator.batchcreateteamproject(settingsfilepath, out log); you'll need add reference dll: c:\program files (x86)\microsoft visual studio 10.0\common7\ide\privateassemblies\microsoft.visualstudio.teamfoundation.teamexplorer.dll you still need use xml, bit more elegant. hope looking for. :) good luck, osh

when use generic collections in c# (or .net in general), compiler leg-work developers used have of making generic collection specific type. . . . saves work? now think it, can't right. because without generics, used have make collections used non-generic array internally, , there boxing , unboxing (if collection of value types), etc. so, how generics rendered in cil? doing impliment when want generic collection of something? don't want cil code examples (though ok), want know concepts of how compiler takes our generic collections , renders them. thanks! p.s. know use ildasm @ cil still looks chinese me, , not ready tackle that. want concepts of how c# (and other languages guess too) render in cil handle generics. forgive verbose post, topic quite broad. i'm going attempt describe c# compiler emits , how that's interpreted jit compiler @ runtime. ecma-335 (it's written design document; check out) it's @ knowing how everything, , mean ever

what purpose jmx used for? have been scanning through of tutorials on jmx, register mbeans , invoke mbeans jconsole. if purpose used for, difference between jmx , rmi(remote procedure call). in advance.. 'remote procedure call' distributed computing concept process running on 1 host can call procedure on remote host. rmi in java 1 implementation of concept. mbeans bean classes can registered jmx bus listen events arriving on bus or send events on bus or collect various sorts of data other participating mbeans etc. used health monitoring of application servers etc. can check number of active connections, amount of free memory , many other statistics analysis engine. , yes, can invoked remotely using rpc mechanism. vital functioning data collectors since in cluster of application servers data has fetched collectors , collated @ 1 place analysis.
