i've been using socialsharing plugin in cordova app many months , it's been working great, , rely on fb sharing's callback functionality track if people shared post. however, discovered callback stopped working correctly on ios 8.1. when click on "cancel" in fb dialog popup, plugin calls success function , returns "true" parameter. call success callback, pass in "false" parameter, i'd able determine if "cancel" or "post" button user clicked on. i have tried updating latest version of plugin, still fails on iphone 6 running ios 8.1. if test on ipad running ios 7, cancel button works fine. can please advise on how resolve it? below socialsharing plugin official page: https://github.com/eddyverbruggen/socialsharing-phonegap-plugin thank you. this issue has been solved of today, when facebook updated app. resolve problem, user needs update facebook app. further details available @ facebook bug rep

i using imread function in octave load image: image = imread ("data/images/image1.jpg")(:); this apparently loading image matrix of integers values 0-255. i want load matrix of doubles values 0.0-1.0. can convert this. doubleimage = double(image) / 255.0; however, converting pretty slow, lot of images. there way load image directly matrix of doubles? no, there no way directly read doubles. doesn't make sense anyway, because image integer in file, integers have read first. if conversion type done, makes sense done separated. or maybe, use file format stores images in double floating point precision. however, there better way doing convert double. pkg load image; img = imread ("image1.jpg"); img = im2double (img); using im2double won't make faster (the operation performs same yours) save if in future image read uint16 , , if image of class double. also, don't see how conversion double slow. fast operation.

which technique faster data bulk upload empty db table? which technique faster data inserts / updates non-empty db table? which technique faster when reading data non-empty db table? that such broad question. performance profile of 2 storage engines has nothing in common. use hekaton oltp workloads. use columnstore indexes analytical queries. fact query of columnstore index must scan in total disqualifies oltp-style queries. fact hekaton has extremely limited query plan shapes disqualifies olap applications. so have no choice because applications not overlap.

why use multiple column families in hbase , advantages of these tuples? already documented in official hbase guide, take @ statements in bold: on number of column families hbase not above 2 or 3 column families keep number of column families in schema low. currently, flushing , compactions done on per region basis if 1 column family carrying bulk of data bringing on flushes, adjacent families flushed though amount of data carry small. when many column families flushing , compaction interaction can make bunch of needless i/o loading (to addressed changing flushing , compaction work on per column family basis). more information on compactions, see compaction. try make 1 column family if can in schemas. introduce second , third column family in case data access column scoped; i.e. query 1 column family or other not both @ 1 time. 33.1. cardinality of columnfamilies where multiple columnfamilies exist in single table, aware of cardinality (i.e., number of rows). if colum

i have 2 sites, a , b . a consumes api b exposes, , b requires windows authentication. both sites live in domain d . the api consumed via httpclient , , when site a run locally, under domain account (which in domain p ), access granted. in case, httpclient instantiated so: using(var client = new httpclient(new httpclienthandler { usedefaultcredentials: true })) when a deployed testing server, above results in 401 unauthorized response. application pool on testing server running under service account in domain d . when explicitly using service account this: var credential = new networkcredential("service-account", "password", "d"); var cache = new credentialcache { { new uri(apiserveruri), "ntlm", credential } }; var handler = new httpclienthandler { credentials = cache }; using(var client = new httpclient(handler)) ... and again running site a locally, access still granted. access granted when accessing api d

i using azure redis cache , stackexchange.redis client access it. trying figure out best way update dictionary values in redis. public async task<t> fetchandcacheasync<t>(string key, func<task<t>> retrievedata, timespan absoluteexpiry) { t value; var output = await _cache.stringgetasync(key); if (output.hasvalue) { value = _serializer.deserialize<t>(output); } else { value = await retrievedata(); await _cache.stringsetasync(key, _serializer.serialize(value), absoluteexpiry); } return value; } _cache in above code snippet of type stackexchange.redis.idatabase. on initialization store dictionary object as fetchandcacheasync("diagnostics", () => new dictionary()); i have function called update datetime given key in dictionary object. question: basic knowledge

i want select statement using values have in table variable. declare @emailids table (usrmst_id int) declare @actionids table (tskmst_id int) insert @emailids (usrmst_id) select usrmst_id usrmst usrmst_domain = 'email' insert @actionids (tskmst_id) select tm.tskmst_id tskmst tm inner join tskmail tml on tml.tskmail_id = tm.tskmst_id tskmail_to_int '%' + (select cast(usrmst_id char(5)) @emailids) + '%' select * @actionids this failing because select cast(usrmst_id char(5)) @emailids has multiple results. want each value in @emailids table generate return @actionids table. you can try using inner join instead: insert @actionids (tskmst_id) select tm.tskmst_id tskmst tm inner join tskmail tml on tml.tskmail_id = tm.tskmst_id inner join @emailids e on tskmail_to_int '%' + cast(e.usrmst_id varchar(5)) + '%' you should cast varchar inst

here's small snippet of assembly code (tasm) try increment value @ current index of array. idea "freq" array store number (dword size) represents how many times ascii character seen in file. keep code short, "b" stores current byte being read. declared in data segment freq dd 256 dup (0) b db ? ___________ assume b contains current byte mov bl, b sub bh, bh add bx, bx inc freq[bx] i receive error @ compilation time @ line containing "inc freq[bx]": error argument operation or instruction has illegal size. any insight appreciated. there no inc can increment dword in 16 bit mode. have synthesize add/adc, such as: add freq[bx], 1 adc freq[bx + 2], 0 you might need add size override, such word ptr or change array definition freq dw 512 dup (0) . also note have scale index 4, not 2.

is there way can (probably using uiscrollview) scroll uiscrollview down see 55px (or whatever value want) @ bottom. example have uiscrollview in background scrolls horizontally (contains bgs). can scroll horizontally in change bg. on top of have uiscrollview (vertically scrolling) content. if user scrolls scroll down actual uiscrollview down bottom of screen (it keep top 55px visible) , remains there little tab, allowing user access bg scroller change bg. can (using tab) scroll , uiscrollview goes full screen , can scroll content uiscrollview again. for example google maps app on android, if go place, "tab" of view @ bottom , can drag , scroll in it, , drag down. stays there @ bottom , can drag @ time, gives access view behind (the map in case)

i need run file in terminal (linux). http://manpages.ubuntu.com/manpages/trusty/man1/ncbi-seg.1.html it comes ".1" file. ideas? something (it is, after all, man-page): nroff -man ncbi-seg.1 |less better, if program installed (not ".1" file): man ncbi-seg (section "1" default). a comment notes (at least on linux), man program accepts actual pathname, e.g., man ./ncbi-seg.1 and referring followup, made script, qm in june 1995: #!/bin/sh tbl $* | nroff -man |less since then, (not all) versions of man have incorporated fix automatically run tbl .

in yii php framework, 1 has ability create modules. per yii's official documentation here definition of module : a module self-contained software unit consists of models, views, controllers , other supporting components. in many aspects, module similar application. main difference module cannot deployed alone , must reside inside of application. users can access controllers in module normal application controllers. let's have huge aplication , have create front-end , backend. in case, better create frontend module , , backend module , use them, or better implment frontend 1 yii application, , backend second yii application. i'm asking because if @ yii's 2 advance template , there 3 different applications ( common, backend, frontend ), not implemented 3 different modules, , question why? is app going slower when use modules , pros , cons of using modules? yii2 advance template has 3 different applications frontend, backend , console (
