is possible create vector automatically or progressively dates. want ask user starting date , final date , i'd fill vector dates , ones between both. so abstractly: "what first date?" '...' firstdate = '...' --> "what final date?" '...' finaldate='...' and following, i'd fill in vector of dates between firstdate , finaldate. possible in matlab, , how? there function use? you can use linspace after user input: %// prompt , user input prompt1 = 'what first date? (yyyy-mm-dd)\n'; prompt2 = 'what last date? (yyyy-mm-dd)\n'; startdate = datenum(input(prompt1,'s'),'yyyy-mm-dd') enddate = datenum(input(prompt2,'s'),'yyyy-mm-dd') % number of days numdays = enddate-startdate % array of dates alldays = linspace(startdate,enddate,numdays) datestring = datestr(alldays, 'mm/dd/yyyy') for input 1989-07-01 , 1989-07-07 return: datestring = 07/01/198

im using table viewedposts link users , blogposts. as dont need of data, , experiment on optimisation , bandwidth usage, i'd move relation column. this relation column become large, lets millions of relations. lets want have list of blogs , want know if have been viewed user. i'd need full set of relations paginated blogs, if user has viewed millions of blog posts? i'm pretty sure parse not return millions of relations in user object, truncated. what best solution this? you have answer, think, little restatement: user has relation called viewedblog . gets added-to each time user views blog ("blog post" mean here), can relate zillions of those. that's fine since relation column reference table. when have user, can viewedblog relation, , when relation can it's query . query has features , limitations of regular parse.query (because one). so can set limit 1k, qualify further (say, post tags), sort (say, descending on recency)

is there possibility communicate between multiple instances of application deployed cloud foundry? checked cloud foundry api couldn't find mention of subject. tried hazelcast unfortunately, cloud foundry provider doesn't support multicasting, have know ip addresses of every other instance in order connect. i think can't 1 interested in this. i recommend use messaging service (like rabbitmq) communicate between instances of applications. can store shared information in database service or remote location outside file system. it not practice build applications require type of communication in cloud. each instance should ideally able run independently , stateless.

i'm having doubt time ago, , have end leaving sql scripts outside version control (i try encapsulate code in database as can). but find interesting have version control of both app code , database scripts; having snapshots of database situation (just ddl , stored procedures) in each commit pretty useful. would have app code , sql scripts in different branches (and having cherry-pick, merge, whatever, many times)? do think it's idea? usually, having database-related files e.g. construct database schema or provide migration routines inside application repository fine. after all, application needs database, , repository should provide necessary set up. having scripts there construct database, , import base data required fine. it include scripts provide test data in order run tests (often referred fixtures ). the thing avoid having production data inside repository. else required application run: include in repository.

everyone! i have 2 controllers meant search on websites. can search on them if logged in. so.. tracking post request , data goes file give answer , login page redirects normal logged in page. first controller code $ch = curl_init(); curl_setopt($ch, curlopt_url, self::loginurl); #curl_setopt($ch,curlopt_httpheader,$httpheader); curl_setopt($ch, curlopt_cookie, $cookie); curl_setopt($ch, curlopt_post, true); curl_setopt($ch, curlopt_postfields, $postdata); curl_setopt($ch, curlopt_cookiesession, true); curl_setopt($ch, curlopt_returntransfer, false); curl_setopt($ch, curlopt_followlocation, true); curl_exec($ch); so, goes loginurl, post data , displays 1, instead of website(with me logged in). 1 answer json file give successful login. problem not logged in, if set new curl handler home url. same problem goes second controller, code: $ch = curl_init(self::loginurl); curl_setopt($ch, curlopt

i'm using imagepickercontroller, when select imagen got error: fatal error: unexpectedly found nil while unwrapping optional value i dont know why because im unwrapping value if let func imagepickercontroller(picker: uiimagepickercontroller, didfinishpickingmediawithinfo info: [nsobject : anyobject]) { if let img = info[uiimagepickercontrolleroriginalimage] as? uiimage { photoimageview.image = img } dismissviewcontrolleranimated(true, completion: nil) } does error occurs @ line photoimageview.image = img in case might photoimageview nil (it implicitly unwrapped optional). updated comments: please check photoimageview @iboutlet , connected uiimageview on storyboard. if creating programmatically, try adding view in window before setting image.

i have dataset can simplified in following format: clear input str9 date id vara varb "12jan2010" 5 21 42 "12jan2010" 6 47 21 "15jan2010" 10 7 68 "17jan2010" 6 -5 -3 "19jan2010" 6 -1 -1 end in dataset, there date, id, vara, , varb. each id represents unique set of transactions. want collapse (sum) vara varb, by(date) in stata. however, want keep date of first observation each id number. essentially, want above dataset become following: +--------------------------------+ | date id var1 var2 | |--------------------------------| | 12jan2010 5 21 42 | | 12jan2010 6 41 17 | | 15jan2010 10 7 68 | +--------------------------------+ 12jan2010 17jan2010 , 19jan2010 have same id, want collapse (sum) var1 var2 these 3 observations. want keep date 12jan2010 because date first observation. other 2 observations dropped. i know might possible collapse id first , merge original datas

why getting empty data messages when read topic kafka? problem decoder? *there no error or exception. thank you. code: def main(args: array[string]) { val sparkconf = new sparkconf().setappname("queue status") val ssc = new streamingcontext(sparkconf, seconds(1)) ssc.checkpoint("/tmp/") val kafkaconfig = map("zookeeper.connect" -> "ip.internal:2181", "group.id" -> "queue-status") val kafkatopics = map("queue_status" -> 1) val kafkastream = kafkautils.createstream[string, queuestatusmessage, stringdecoder, queuestatusmessagekafkadeserializer]( ssc, kafkaconfig, kafkatopics, storagelevel.memory_and_disk) kafkastream.window(minutes(1),seconds(10)).print() ssc.start() ssc.awaittermination() } the kafka decoder: class queuestatusmessagekafkadeserializer(props: verifiableproperties = null) extends decoder[queuestatusmessage] { override def frombytes(bytes: array[byte]): queuestat

when invoke next code: response response = target.request(mediatype.application_json_type) .post(entity.entity(form, mediatype.application_form_urlencoded_type)); response.getentity(); response.getentity() null. but when invoke: jsonobject json = target.request(mediatype.application_json_type) .post(entity.entity(form, mediatype.application_form_urlencoded_type), jsonobject.class); variable json not null. i need use first variant because need check response status. why first code not working?and how can status code then? you need use response.readentity(your.class) return instance of type want. example string rawjson = response.readentity(string.class); // or jsonobject jsonobject = response.readentity(jsonobject.class); note there needs provider handle reading java type , application/json. if using jersey , json-p api, see this . general information providers, see this

i tend use following notation lot: const datum& d = a.calc(); // continue use d this works when result of calc on stack, see http://herbsutter.com/2008/01/01/gotw-88-a-candidate-for-the-most-important-const/ . though compilers optimize here, feels nice explicitly avoid temporary objects. today realized, content of d became invalid after data written member of a . in particular case function returned reference member, unrelated write however. this: const datum& d = a.get(); // ... operation ... a.somedata = datum2(); // d invalid. again, somedata has nothing d or get() here. now ask myself: which side-effects lead invalidation? is bad-practice assign return values const reference? (especially when don't know interior of function) my application single-threaded except qt gui-thread. which side-effects lead invalidation? holding reference internal state of class (i.e., versus extending lifetime of temporary) , calling non-const member f
