using grep , can print occurrences of uppercase letter "z" in document. output, however, display entire lines in every "z" in document found. need limit printing 10 letters appearing before every occurance of "z". e.g., if document has line "aaaabbbbbbbbbccccccdddddddz", print "ccddddddd", 10 letters appearing before. if there fewer 10 letters prior "z", nothing needs printed. if "z" appears multiple times in single line, 10 letters preceding each of these "z"'s should printed, e.g.: "aaaabbbbbbbbbzcccccdddddddz" print "abbbbbbbbb" , "ccdddddddz". the result output list of these letters, e.g.: abbbbbbbbb ccdddddddz how can print 10 letters preceding every occurrence of letter "z" in document? simple: grep -op '.{10}(?=z)' <<< aaaabbbbbbbbbzcccccdddddddz explanation: -o : print match, not entire line -p : use

maybe question before wasn't able find relevant answer needs. ask how people make loading text, text grey example , left right becoming white while page load. when reach end - page loaded , page show. same thing spinners... or example how make page show loading 0%, 1% - 100% , when it's 100% page load... best way accomplish this? thanks. some comments here not possible without flash have seen done in pure html before. common in complex demo / visualisation apps , web apps. the trick page loads javascript code kicks in preload images , other resources cache. can monitor progress of using javascript , update progress bar while you're doing it. this article discusses caching images first comment @ end links article caching other resources: http://www.useragentman.com/blog/2012/01/16/caching-images-with-javascript-and-html5-progress-bars/ i've seen done quite lot if page loads lot of content through ajax request. enable require quite structural chan

i have file 20.000.000 lines , each day file added or removed lines , need crontab, need each day obtain 9 files of 50.000 lines. for example: bigfile file 20.000.000 lines. and need generate 9 files, first file line 1 50000, second file line 50001 100000, third file line 100001 150000 . . . i can't split first time because file change days, , second problem have if first time obtain 9 files second day need continue last line use. for example first day use 450.000 lines, second day need first line line 450001 500000, , third day need use 900001 first file. the split not works because if use split first time, files change, files have not work second day can me? use split command ( manpage ). for example: $ split -l 50000 /path/to/bigfile

i'm trying find best way display posts saved in wordpress on site. i've found various options far problem i'm getting can't seem find answers on when post displayed, none of formatting kept, example, in main content of post, paragraphs, bullet points , font stylings aren't displayed. if add image post appears left out. i'm hoping best way php , mysql, looking throught wordpress files i'm unsure how structured. wordpress directory located in same directory of site (e.g mysite/wordpress) this maybe many other people have asked i'm struggling find correct terminology inorder search answer. you don't need connect directly blog database. can create new file in wordpress directory , include wp-blog-header.php file: example: <?php require('./wordpress/wp-blog-header.php'); // change fit path ?> <p>recent posts:</p> <ul> while (have_posts()) : the_post(); ?> <li><?php the_title(); ?> <

given following active pattern: let (| hasmatch |) (x:string) = if x.contains("0") some() else none;; and following pattern matching func: let testfn x = function | hasmatch -> printfn "%a" | _ -> printf "nope";; the last line's wildcard pattern says warning fs0026: rule never matched all of examples see seem infer partial active patterns must return some('a) match, , ones return none captured wildcard. error seems differently. what missing? i think should add none case active pattern declaration follows: let (| hasmatch | _ |) (x:string) = if x.contains("0") some() else none;; in orignal example, compiler infers want return option type. when run printf in example, see print some null when there match. also, bad return some() , should return some(x) or similar

because working non-kvc rest service have need designate bool attribute isspecial request url rather of returned json. instance, if make request http://www.service.com/getobject?isspecial=no specify attribute isspecial no . can accomplish effect adding multiple response descriptors, 1 each of getobject?isspecial=yes , getobject?isspecial=no , need have way of defining special attribute mapping - not mapping attributes key paths key paths, rather request url. how might accomplish this? you @ using routing path patterns , using pattern meta data during mapping. i'm not sure can pull out queries individually may need have method on managed object subclass takes meta data , extracts parts want store.

i need show new comments user in real-time (similar youtube's live comments system no auto-adding). maybe need use pools asyn controller handle requests , show if user clicks on "show more 10 comments". or, example, similar stackoverflow's alert new inbox messages. it looks you're wanting 'push' data user in real-time. previously might have been done bit of 'hack' solution known long-polling with long polling, client requests information server in way similar normal polling; however, if server not have information available client, instead of sending empty response, server holds request , waits information become available (or suitable timeout event), after complete response sent client. however might want html5 world of websockets . i'd recommend reading on signalr , following tutorials (watch pluralsight videos). asp.net signalr new library asp.net developers simplifies process of adding real-time web function

i confuse explain question/problem, best so. i want write formula display value cell jumping cell in particular sequence. e.g. column d =a1 =a6 =a11 =a16 ----- ---- ----- it sequence of 5 cells write 2 rows formula =a1 , =a6 , drag formula , got as =a1 =a6 =a3 =a8 anyone please guide me. you can use offset() , row() =offset($a$1,(row()-1)*5,0) paste in d1 , copy down as example if have in a values correspond row numbers you'll following sample outcome | b | c | d ------------------ 1 | | | 1 2 | | | 6 3 | | | 11 4 | | | 16 5 | | | 21 6 | | | 26 7 | | | 31 8 | | | 36 9 | | | 41 ... explanation: offset() returns reference range specified number of rows , columns cell or range of cells. row() returns row number of reference. therefore formula evaluated to: for d1 - go 0 ((1-1)*5) rows , 0 columns a1 a1 (1+0) for d2 - go 5 ((2-1)*5) rows , 0 columns

i used read files this: f = [i.strip("\n") in open("filename.txt")] which works fine. prefer way because cleaner , shorter traditional file reading code samples available on web (e.g. f = open(...) , line in f.readlines() , f.close()). however, wonder if there can drawback reading files this, e.g. since don't close file, python interpreter handles itself? there should careful of using approach? this recommended way: with open("filename.txt") f: lines = [line.strip("\n") line in f] the other way may not close input file long time. may not matter application. the with statement takes care of closing file you. in cpython, letting file handle object garbage-collected should close file you, in other flavors of python (jython, ironpython, pypy) can't count on this. also, with statement makes intentions clear, , conforms common practice.

hello i'm trying create take program path , put in in registry file, keep on having error. here code: #include <iostream> #include <windows.h> #include <winuser.h> #include <tchar.h> #include <limits> using namespace std; void reg() { char buffer[max_path]; getmodulefilename(null,buffer,sizeof(buffer)); const unsigned char path[ max_path ] = {buffer}; ::hkey handle_key = 0; ::regsetvalueex( handle_key, "my directory", 0, 1, path, sizeof path ); }; the error i'm getting says invalid conversion 'char*' 'unsigned char' [-fpermissive] i have spent hours looking solution, can't find one. the problem, i'm guessing, line const unsigned char path[ max_path ] = {buffer}; the problem here try create array of single characters character pointer. you use variable temporary regsetvalueex call, don't need it. instead call function buffer directly. also, should not use sizeof here

i have c# property on server side , setting on http request. property value persist request? sorry if silly one? in general, no. persist if it's property of stored in session variables (for example in controller's tempdata or in application session data), or if have other custom mechanism preserves value across requests. refer state management recommendations page on msdn overview of options.

anyone know happens when call function double () so get_separate_save_methods_function(url, false); becomes get_separate_save_methods_function(url, false)(); i've never seen before seems change false argument true, when remove () same argument becomes false. it's not code , i'm trying work out if mistake or has been done of purpose. no, () doesn't change argument false true . get_separate_save_methods_function(url, false)(); can used when get_separate_save_methods_function(url, false) returns function. calls returned function. given get_separate_save_methods_function name, not mistake it's hard tell more code.

i'm working on c# component consists of 2 dlls: a .dll written in c++/cli exporting symbol; unfortunately, dll dynamically links against crt , there doesn't seem way around that. a c# assembly. the c++/cli dll gets loaded , loads c# assembly (and forwards calls it). possibly simplify scenario export symbol c# assembly right away? you can export functionallity c# com server way should pretty easy call c++ other non-c# com object.

i don't understand why when commits new file shows on end if deleted , re-written same thing when didn't touch file. we both use windows. idea causes , how avoid it? they're not same, or else git wouldn't have mentioned different. there 1 possibility if else looks same: stuff can't see must different, i.e. white space. it's not space/tab kind of issue based on screen shot. it's either white space @ end of line (like spaces) or ever more cr/lf issue using windows. you need set core.eol , core.safecrlf , core.autocrlf . in particular, if set core.safecrlf true git yell @ if edited incorrectly. if want check happened, you'll need open in checkin via it's tag , check line-endings using editor can display them, or can check size before , after. crlf version of file should longer because of cr. in fact, should (based on diff) 108 bytes longer.

please tell me how access system restore "rstrui.exe" c# code. i tried calling c:\windows\system32\rstrui.exe ; not accessible @ all. i need call function redirecting controls system restore. thanks.... you can access c:\windows\system32 using following property: environment.systemdirectory environment.systemdirectory property you can run executable using following method: process.start(path.combine(environment.systemdirectory, "rstrui.exe")); path.combine method process.start method update >>> ahhh... see problem. when accessing system32 folder 32 bit code on 64bit windows 7 , vista (maybe windows 8 too), windows 'cleverly' changes part of request path syswow64 . why may have got 'could not find path' error. in order around this, can use following: process.start(@"c:\windows\sysnative\rstrui.exe"); a more complete answer might be: if (environment.is64bitprocess) { process.start(path

my delphi application using postgresql database (with unidac components). data stored in utf8 in database. read international characters, use handler: procedure tdmmain.ongettext(sender: tfield; var text: string; displaytext: boolean); begin text := utf8decode (sender.asstring); end; but, how possible store data, db? created handler, onsettext , sender.asstring := utf8encode (text); not working. how possible that? thanks. when reading , editing data, don't need recode utf-8 text (for example, in ongettext event). enough set useunicode option in tuniconnection.specificoptions property true , example, follows: uniconnection1.specificoptions.values['postgresql.useunicode'] := 'true'; and unidac automatically. http://www.devart.com/unidac/docs/pgsqlprov_article.htm

when define variable lists shown below , type lists in console, error referenceerror: lists not defined var lists = new meteor.collection('lists'); if (meteor.isclient) { template.hello.greeting = function () { return "my list."; }; template.hello.events({ 'click input' : function () { // template data, if any, available in 'this' if (typeof console !== 'undefined') console.log("you pressed button"); } }); } if (meteor.isserver) { meteor.startup(function () { // code run on server @ startup }); } it works if declare lists global variable: lists = new meteor.collection('lists'); question: why must scoped global? to access lists in console need use global scope console outside scope of file console considered own file. with var can access lists anywhere in file. in essence each file wrapped in function() {..} . why each file's variables can

any_t type ( int , struct something , …). consider structure: struct my_struct { any_t val, any_t array[10] } if define variable v : struct my_struct v; is safe use &v.val array of 11 any_t items? any_t *p = &v.val; f(p[0]); f(p[5]); f(p[10]); is guaranteed no padding added between val , array ? from c standard alone, not safe use &v.val array of 11 any_t these reasons: the c standard permits unnamed internal padding in struct: c 2011 (n1570) 6.7.2.1 15, “there may unnamed padding within structure object, not @ beginning.” unusual c implementation insert padding between val , array , because alignment requirements not require it, permitted , conceivably beneficial in circumstances, such causing array better aligned performance (rather necessity). even if there guarantee spacing of val , array elements same array of 11 any_t , there no guarantee pointer arithmetic works. c 2011 (n1570) 6.5.6 8 defines pointer arithmetic (inclu

i'm developing android app, , after user registers, i'd send him verification email according mail entered in registration process. i saw several answers here have same problem: only gmail send mail self , know username , pwd. how can can send no matter mail provider? i have php backend, better there? i go back-end, several reasons: if there central back-end handles administration, should in charge of user administration , confirmation. sending email phone means more data usage user. sending email phone works if user on network allows smtp-connections outside own subnet. many isps, example, not allow that.
