i created simple site handle uploads collectionfs, http://uploadapp.meteor.com/ , when click on upload uploads file as3 bucket if click on uploaded image in site , copy url gives me local url example: http://uploadapp.meteor.com/cfs/files/videos/tn877rsltc2s6snwg/download%20(1).jpeg?token=eyjhdxrovg9rzw4ioijhykpzvkz4v0dolulcqmjpbzdrduxxs3vuq3fdwdfboutsnzbbv1p3x0t3in0%3d this means image showing uploading mongodb , as3? how can make show , upload , directly as3? (the images stored as3 bucket upload working) the event handler upload form : template.hello.events({ 'change .fileinput':function(evt,tmpl){ fs.utility.eachfile(event,function(file){ var fileobj = new fs.file(file); videos.insert(fileobj),function(err){ console.log(err); } }) } }); the url proxy actual image. reason it's needs sign url displayed. it's not on mongodb on s3.

the cells in table view not auto-sizing height contain content. using "basic" style cell prototype. created new test project containing view controller , storyboard , has same issue. doing wrong? rowheighttestcontroller: @implementation rowheighttestcontroller #pragma mark - table view data source - (nsinteger)numberofsectionsintableview:(uitableview *)tableview { // return number of sections. return 1; } - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section { // return number of rows in section. return 2; } - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:@"test" forindexpath:indexpath]; // configure cell... cell.textlabel.text = @"testing"; cell.textlabel.font = [uifont systemfontofsize:60 + indexpath.row]; return cell; } @end the storyboard:

i using pubsub gmail push notifications. the pubsub subscription recieves messages expected. when pull messages have noticed if there no messages pull delay in getting response slow. if there @ least 1 message pull response timely has else experienced this? the fix can come leave message on queue. if (credential.requestaccesstokenasync(cancellationtoken.none).result) { var pubsubserivce = new google.apis.pubsub.v1beta2.pubsubservice( new baseclientservice.initializer() { httpclientinitializer = credential, applicationname = "ilink", }); pullrequest pr = new pullrequest(); pr.maxmessages = 100; pullresponse prs = pubsubserivce.projects.subscriptions.pull(pr, "projects/vivid-canyon-90023/subscriptions/ilink").execute(); acknowledgerequest ak = new acknowledgerequest(); if (prs != null && prs.receivedmessages != null) { ak.ackids = new list<string>();

i have been using this: char appdata[250]; expandenvironmentstrings("%appdata%\\\mcpcmodlocator\\", appdata, 250); in c++ win32 appdata folder on 1 of projects. worked fine, no issues. on newest project (same pc, still in visual studio 2013) when try that, error on first string saying "const char* incompatible type lpcwstr" , on second parameter says "char * incompatible type lpwstr". have no idea why work on first project, not second. assume setting change, looking through each projects settings, see nothing. appreciated! thanks! by default, newly created project in vs2013 has been set use unicode apis, use lpwstr (or, wchar_t*) instead of lpstr(or, char*). you can call old ansi version apis add "a" @ end of function name explicitly e.g. expandenvironmentstringsa or change project configuration use multibyte character set(project property pages -> configuration properties -> general -> character set)

i'm trying use fulltext index in order facilitate searching forum posts. it's not working in way expect, , i'm trying understand why not. for example, know there 1 post contains phrase "haha , got three" , perform query select * forum_posts match(message) against ('"haha , got three"' in boolean mode); and expect, find single post includes phrase. hooray! but perform related query: select * forum_posts match(message) against ('"and got three"' in boolean mode); and no results. in fact, searching word "three": select * forum_posts match(message) against ('three' in boolean mode); yields no results either. what going on? i think need learn stop words , minimum word length. my default, mysql ignores stop words in full text index. here list of them. "and got three" stop words. in addition, default, mysql ignores words less characters. controlled parameter. explained

i trying django app running on amazon ec2. have .pem file saved in root of django project. when try this chmod 600 oby.pem ssh -i oby.pem ubuntu@52.0.215.90 in mac terminal, receive error: permission denied (publickey). to begin, saving oby.pem file in right location? if not, should go? furthermore, necessary steps correctly set ssh key? thank you!

in "95% of performance clean representative models" talk martin thompson , between 17 , 21 minute, such code presented: public class queue { private final object[] buffer; private final int capacity; // rest of code } in 20:16 says: you can better performance, leaving things capacity in there right thing do. i tried come code example in capacity faster buffer.length , failed. martin saying problems arise in 2 scenerios: in concurrent world. but, length field final , jls 10.7 . so, don't see how problem. when cache misses. tried calling capacity vs buffer.length 1 million times (with queue having 1 million of elements), there no significant difference. used jmh benchmarking. could please provide code example, demonstrates case in capacity superior buffer.length in terms of performance? the more common case (frequently spotted in real code), better. please note, i'm totally taking away aspect of aesthetics, clean c

is there anyway ( workaround ) define type synonyms in java, similar following definition in scala? type row = list[int]; though might not same, thinking of following code ( replaced list arraylist, since list interface in java): public class row extends arraylist<integer>{} is there other way achieve type synonym mechanism in java? unfortunately not. see is there java equivalent or methodology typedef keyword in c++? older duplicate of question, using c++ terminology instead of scala terminology.
