i using swift 2 xcode 7.2 in extension. rendering uitableview cells have image , label in problem image hidden ! idn't know why! can me please override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell { let cell = tableview.dequeuereusablecellwithidentifier("cell", forindexpath: indexpath) uitableviewcell cell.textlabel!.textcolor = uicolor.whitecolor() let query = pfquery(classname:"recipe") query.orderbydescending("createdat") query.findobjectsinbackgroundwithblock { (objects: [pfobject]?, error: nserror?) -> void in if error == nil { print("success retrieved \(objects!.count) scores.") if let objects = objects { object in objects { let a:string = object.objectforkey("title") as! string self.contentstring.append(a) }

i had small conflict in .h header file in project i'm working on. project tracked in git. fortunately, conflict simple solve. used git mergetool and chose default ( opendiff ) seemed filemerge on mac. made appropriate changes, saved file, , closed. git asked me if merge successful, said yes: was merge successful? [y/n] y but now, have: > git st # on branch develop # changes committed: # modified: myheader.h # # untracked files: # (use "git add <file>..." include in committed) # # myheader.h.backup.52920.h # myheader.h.base.52920.h # myheader.h.local.52920.h # myheader.h.remote.52920.h # myheader.h.orig which of junk conflict files created filemerge, , git? and more importantly: how remove them? you can delete them other file. example: rm myheader.h.orig alternatively, if there no other untracked files, after commit with git commit -a you may clean repository with git clean -n git clean -f git clean -n

i running fft algorithm detect music note played on guitar. the frequencies interested in range 65.41hz (c2) 1864.7hz (a#6). if set sampling frequency of input 16khz, output of fft yield n points 0hz 16khz linearly. input interested in first n/8 points approximately. other n*7/8 points of no use me. decreasing resolution. from nyquist's theory ( https://en.wikipedia.org/wiki/nyquist_frequency ), sampling frequency needed twice maximum frequency 1 desires. in case, 4khz. is 4khz ideal sampling frequency guitar tuning app? intuitively, 1 feel better sampling frequency give more accurate results. however, in case, seems having lesser sampling frequency better improving resolution. regards. you confusing pitch of guitar note spectral frequency. guitar generates lots of overtones , harmonics @ higher frequency pitch of played note. higher harmonics , overtones, more possibly weak fundamental frequency in cases, human ear hears , interprets lower perceived pitch

i create antiplagiat. use shingle method. example, have following shingles: i go cinema i go cinema1 i go th cinema is there method of calculating equal hash these lines? i know of existence of levenshtein distance. however, not know should take source word. maybe there better way consider levenshtein distance. the problem hashing that, logically, you'll run 2 strings differ single character hash different values. small proof: consider possible strings. assume of these hash @ least 2 different values. take 2 strings , b hash different values. can go b changing 1 character @ time. @ point hash change. @ point hash different single character change. some options can think of: hash multiple parts of string , check each of these hashes. won't work since single character omission cause significant difference in hash values. check range of hashes. hash 1 dimensional, string similarity not, won't work either. all in all, hashing not way go.

i made new topic issue. kim told\ anonymous requests typically means not find username/password not token in clients request. remember token on first request should reused subsequent requests client code (all kbmmwsimpleclient, kbmmwclientquery, kbmmwclientresolver etc). on way centralize put tkbmmwsimpleclient on datamodule , specify client query components use simple client instance template. first thing before else in client application, make initial "login" request call via simpleclient. i changed serversidequeryallclick on client app. copied token server side client edit1.text. procedure tform1.btnnamedserversidequeryallclick(sender: tobject); begin // gets records server event table. if length(trim(edit1.text)) > 0 begin kbmmwsimpleclient1.disconnect; kbmmwsimpleclient1.username:= cb1.text; // login -> franz kbmmwsimpleclient1.password:= cb2.text; // password -> franzpassword

i trying use qsort on array of structs error: expected primary-expression before '*' token struct muchie { int x,y,c; } a[100]; int cmp(const void* p, const void* q) { muchie vp,vq; vp=*(muchie* p); vq=*(muchie* q); return vp.c-vq.c; } // .... qsort(a,m,sizeof(muchie),cmp); the casting of parameters wrong - should *(muchie*)p instead of *(muchie* p) . use: int cmp(const void* p, const void* q) { muchie vp,vq; vp=*(muchie*) p; vq=*(muchie*) q; return vp.c-vq.c; }

i have these 2 tables: table p | b --------- x | 2 x | 7 x | 10 x | 28 y | 24 mapping m c | d ----------- 7 | 2136 28 | 786 24 | 4212 124 | 5311 935 | 6012 if can find matching value of column b in table p value in column c of mapping m, need add value of column d table p well. for example, 1st record of x , 2 of table p, can't find 2 in column c of mapping m, nothing added. 2nd record x , 7, can find 7 in column c, gonna add x , 2136 table p. hence added table p: x | 2136 x | 786 y | 4212 i find challenging insert these 3 rows. i can this: select p.*, m.d @tablep p join @mappingtable m on (p.b = m.c) and put result temp table , insert, how do in 1 insert statement? i realized it's quite straightforward: insert @tablep select p.a, m.d @tablep p join @mappingtable m on (p.b = m.c)

i've got text boxes wanted set placeholdertext property. text of each box bound property of underlying view model. when setting placeholder in xaml that <textbox placeholdertext="placeholder" text={binding propertyname} /> i noticed, view model's properties not updated anymore when text box loses focus. whereas without placeholder binding works fine. is behaviour intended , if there workarounds, or have stick classic textblock describes intended input each box? edit: property implement inotifypropertychanged , binding updated in view model when no placeholder set. placeholdertext textbox not change textbox behavior when loses focus. you can try explicitly using "twoway" binding mode text property, instead of "default" binding mode. <textbox placeholdertext="placeholder" text="{x:bind propertyname, mode=twoway}" /> make sure view's datacontext set viewmodel, below public mainpa

i have folder called "raw" in res folder selection of short audio tracks , screen displays several buttons. i able start mediaplayer this... string[] track = {"track1", "track2", "track3", etc...} mplayer = mediaplayer.create(this, r.raw.track[x]); the issue r.raw.track[x] . is there way in way i'm attempting or need whole new approach? thanks in advance advice can offer. i going assume here x index, perhaps pulled user selection track . you have 2 main options: have corresponding int[] {r.raw.track1, r.raw.track2, ...} , r.raw value way use getresources().getidentifier() identifier @ runtime the second option easier uses reflection , not super-quick. in case, should not matter, doubt looking these ids in tight loop.

this question has answer here: how remove elements @ set of indices in vector in matlab? 1 answer in r, can following: v <- 11:20 v[-(4:5)] and 11 12 13 16 17 18 19 20 , indices except 4th , 5th. is there equivalent in matlab's indexing logic? however wrap mind around it, not seem correct search terms google own result elementary question. note: of course might use of set functions, e.g. v = 11:20; v(setdiff(1:length(v), 4:5)) however, not intuitive. an alternative remove elements array: u = v; u(4:5) = []; i'm using temporary variable since don't know if it's acceptable modify original array v or not.

suppose have web application ebook shopping, users can download books have paid. , ebooks data(like epub data) stored in s3, users got s3 download url when our app validated user bought 1 book. i know s3 generate temporary , time-limited urls user. problem url temporary , time-limited, happen if chance user temporary url within limited time? ok 1 way seems letting limited-time short, 10 seconds, potential risks still there. i know question rigorous, how deal it? or forget it? if concern buyer distribute url, equally distribute file they've downloaded. if concern hold of url without buyer's knowledge, perhaps protect download token buyer know (e.g. password of sort). make url unusable other buyer. downside inconvenience people who've paid product.
