HTML5 History API with Standard links -

so, after redesigning site, thought use html5 history api, when saw brilliant use of here: http://diveintohtml5.ep.io/examples/history/casey.html problem is, code provided doesn't work me, (using chrome 8). not entirely sure why, refreshes page href value of link after partial content loaded. are there other examples of use of api? dont want history.js or uses hash/hashbangs fallback. i'm trying rid of these. any ideas? edit: firebug throws 'link has no value' @ me countless requests partially loaded content. after these page refreshes you have intercept link click , call own pushstate - if check out code on page see event handler: function addclicker(link) { link.addeventlistener("click", function(e) { if (swapphoto(link.href)) { history.pushstate(null, null, link.href); e.preventdefault(); } }, true); }

mysql - Using :include and :conditions creates big queries? -

is there way create windows installer using visual studio 2008 target both x86 , x64 operating systems. in targetplatform property, have : x86 , x64 , itanium . , know there 1 somewhere called any cpu can't find it. also, don't want create 2 setup. any ideas ? thanks. it can done, not directly visual studio. general approach this: create generic msi contains both 32-bit , 64-bit resources create mst transforms (one 32-bit , 1 64-bit) modify msi based on target platform use exe bootstrapper dynamically detect platform , apply correct transform msi you can create transforms orca . if want commercial solution, can try advanced installer or installshield. if seems complicated, can use separate 32-bit , 64-bit packages.

VS 2005 Compile on Save C# -

-
this baffling me, unable find setting if exists. 90% sure code used compile on save before. started having issue when using c#, .net worked fine. but able rid of error lines etc, when choosing enter debug mode. example when have method public bool method1(){ //no code added yet blue line saying return } even when add return inside method line remains there on save. goes away when build. (this 1 example seems happen lots of other things) edit - in regards options compile on save. the options in build , run set correctly that should produce red underline , entry in error list window: "not code paths return value". produced intellisense parser, not compiler. saving file not remove error hint, opening project does. , fixing code of course. there bug of sorts in logic, in cases error list doesn't purged. workaround i've seen restart visual studio. i've seen intellisense warnings , affects error list, not editor. can't remember ex...

How to list conflicted files (files with changes in both parents) in a git merge commit? -

qgit has nice option of seeing "interesting" files in merge commit, interesting file defined file has changes in both parents. corresponding command line see such files? git show --name-status sha1_of_merge will show commit message , files modified in both parents ( mm ). e.g. git.git repository in commit d907bf8ef32: merge branch 'jc/index-pack' see: $ git show --name-status d907bf8ef327cd47433d4a4bb0a1bb4e96b6e340 commit d907bf8ef327cd47433d4a4bb0a1bb4e96b6e340 merge: 54dbc1f 3de89c9 … mm builtin/index-pack.c mm builtin/pack-objects.c mm cache.h mm csum-file.c mm fast-import.c mm sha1_file.c if don't care commit message , such, git show manpage points format used merge commits: git diff-tree --cc . so, if want see commit hash , "interesting files" use: $git diff-tree --cc --name-status d907bf8ef327cd47433d4a4bb0a1bb4e96b6e340 d907bf8ef327cd47433d4a4bb0a1bb4e96b6e340 mm builtin/index-pack.c mm bui...

signals - Python-dbus extra param to add_signal_receiver -

i'd pass param add_signal_receiver or somehow path signal received from. it's defined that: bus.add_signal_receiver(handle_signal, 'remotedevicefound', 'org.bluez.adapter', 'org.bluez', '/org/bluez/hci'+x) def handle_signal(address, cls, rssi): xxxx i wan't have many signal receivers @ same time , able read 'x' inside handle_signal function. the python dbus documenation has answer . provides following example pass sender handler function: def handler(sender=none): print "got signal %r" % sender iface.connect_to_signal("hello", handler, sender_keyword='sender') so, instead of using bus.add_signal_receiver , create interface signal providing object first , connect signal in example.

i've installed solr 1.4.1, can't tika 0.4 (which included in contrib/extraction) work correctly. i'm getting 404 error when attempting hit http://localhost:8080/solr/ss/update/extract ("ss" core). i've moved of contrib/extraction jars web-inf directory of solr after has been deployed, "solr-cell" jar resides in "dist" directory. the method used above worked solr 3.3, pdf parsing broken in tika 0.8, decided revert solr 1.4.1 , tika 0.4. i'm using tomcat 7.0, if helps. i resolved issue. i had copied multicore directories ("core0" , "core1" in example/multicore) , using stripped down versions of solrconfig.xml. referred default example (located in example/solr) , grabbed "requesthandler" section "update/extract" , placed in stripped down version of solrconfig.xml , restarted solr web app within tomcat , file parsing works perfectly. i hope helps else.

optimization - Switching between in-memory and WCF service? -

imagine have following, standard wcf, code : [servicecontract] interface icustomerservice { [operationcontract] customer getcustomer(); } public icustomerservice { public customer getcustomer() { return mystore.whatisneeded(); } } this working , allows me distribute service , consuming code. is possible (and idea) bypass wcf engine if working in single box ? in fact, want app able run on farm servers, or on small single box servers. to reduce wcf messaging cost, i'd have : icustomerservice service = null; if(singlebox) { service = new customerservice(); // direct instanciation of service class. no wcf here ... } else { service = new customerserviceclient(); // wcf client } var cust = service.getcustomer(); if wrapped properly, can technique reduce server charge ? this surely reduce overhead of wcf runtime. i'd create factory class check if(singlebox) , new right implementation of icustomerservice.

mapping - Alt key shortcuts not working on gnome terminal with Vim -

i'm running vim on gnome terminal. alt key mappings not working. for example (this example): :imap <a-i> <esc> it works fine in gvim. when run same command vim in gnome terminal doesn't work. so think problem terminal, right? how can fix it? thanks edit: have windows 7 installed on same machine, , windows terminal works fine too. the problem there 2 ways terminal emulator send alt key (usually called meta key actual terminals didn't have alt). can either send 8 bit characters , set high bit when alt used, or can use escape sequences, sending alt-a <esc>a . vim expects see 8 bit encoding rather escape sequence. some terminal emulators such xterm can set use either mode, gnome terminal doesn't offer such setting. honest in these days of unicode editing, 8-bit encoding not such idea anyway. escape sequences not problem free either; offer no way of distinguishing between <esc>j meaning alt-j vs pressing esc follow...
