i've been working through eloquent javascript 's exercises , found out think odd. wrote trivial array-flattening piece of code: var arrays = [[1, 2, 3], [4, 5], [6]]; var out = arrays.reduce(function(acc, next){ return acc.concat(next); }); console.log(out); // → [1, 2, 3, 4, 5, 6] so far good. didn't seem pretty me, rewrote as: var arrays = [[1, 2, 3], [4, 5], [6]]; var my_concat = function(acc, next){ return acc.concat(next); } var out = arrays.reduce(my_concat); console.log(out); // → [1, 2, 3, 4, 5, 6] it better, need introduce function, anonymous or named, such basic thing? array.prototype.concat.call 's call signature need! feeling smart, rewrote code again: var arrays = [[1, 2, 3], [4, 5], [6]]; var out = arrays.reduce([].concat.call); // → typeerror: arrays.reduce not function (line 2) well, haven't turned out expected. error message seemed cryptic me. i decided investigate. works: var arrays = [[1, 2, 3], [4, 5], [6]]; var my_concat = fu

the code below simple. know, if string::find() didn't find matches returns -1. reasons code below doesn't work. everytime run code endless loop. thank help! #include <string> #include <iostream> using namespace std; int main() { string text; text = "asdasd ijk asdasd"; string toreplace = "ijk"; cout<<text<<endl; int counter = 0; while ( text.find(toreplace) != -1) counter++; cout<<counter<<endl; system("pause"); } aside other answers correct, wanted add while loop have produced endless loop anyway. example: while(text.find(toreplace) != std::string::npos) counter++; will endless loop because keep trying find toreplace string in text , find (that's because find starts beginning of string each time). not intended.

i'm struggling implementation of dates in sqlite3 (for android). according documentation ( https://www.sqlite.org/datatype3.html , http://www.sqlite.org/lang_datefunc.html ), sqlite doesn't have datatypes date , time , therefore can either stored text or integer. i've tried both, give same erroneous results. after reading lot on internet , trying can think of, come here last resort. so, problem. idea simple. have table containing items, date column. want select items database have date of today, or before (i.e. today or in past). in current implementation store dates integers, since people seem agree that way go. below (simplified) code inserting item. calendar calendar = gregoriancalendar.getinstance(); calendar.set(calendar.hour_of_day, 0); // might not necessary calendar.add(calendar.day_of_year, 4); // today plus 4 days sqlitedatabase db = dbopenhelper.getwritabledatabase(); contentvalues values = new contentvalues(); values.put(column_date, calendar.gettim

some dlls special , operating system load official installed copy regardless of whether file name found on path. what makes special ? on versions of windows earlier win10, “universal crt” might installed via ms-supplied official installer. happen put in system32 directory found , or make special ? likewise compiler rtl redistributals (msvcp140.dll, vccorlib140.dll, vcruntime140.dll). i suspect programs drop these locally, in same directory exe, , put directory on path, causing load errors in unrelated programs don't. in particular, if 1 of dlls found along path , wrong platform (32-bit vs 64-bit) cause cryptic dialog box appear when program attempts run. even though local installation of aforementioned dlls discouraged in favor of using official installers, work or every app need install locally prevent being damaged unrelated programs on path? how can "local install" program (that is, unpacking directory , running there) cope? i'm interested in

i have list: my_list = [1, 2, 3, 4, 5] how can multiply each element in my_list 5? output should be: [5, 10, 15, 20, 25] you can use list comprehension: my_list = [1, 2, 3, 4, 5] my_new_list = [i * 5 in my_list] >>> print(my_new_list) [5, 10, 15, 20, 25] note list comprehension more efficient way for loop: my_new_list = [] in my_list: my_new_list.append(i * 5) >>> print(my_new_list) [5, 10, 15, 20, 25] as alternative, here solution using popular pandas package: import pandas pd s = pd.series(my_list) >>> s * 5 0 5 1 10 2 15 3 20 4 25 dtype: int64 or, if want list: >>> (s * 5).tolist() [5, 10, 15, 20, 25]

so followed "tutorial" here: http://outofcontrol.ca/blog/comments/change-mysql-5.5-default-character-set-to-utf8 and after doing so, mysql 5.7 servers on linux updated , showing expect. but, did same on development machine, macbook pro, el capitan, , see following: character_set_client utf8 character_set_connection utf8 **character_set_database latin1** character_set_filesystem binary character_set_results utf8 character_set_server utf8 character_set_system utf8 character_sets_dir /usr/local/mysql-5.6.10-osx10.7-x86_64/share/charsets/ why still latin1? other entries updated utf8 , worked on linux. character_set_database of virtually no use. don't worry it. when creating table, explicitly state create table (...) ... character set utf8; that helps avoid various changes defaults may occur or in future. actually, future utf8mb4 collation utf8mb4_unicode_520_ci . as long going 5.7, may go combo. utf8mb4

i have following div aligns left side of screen css #nav { position: fixed; height: 50px; width: 50px; display: block; background-color: #000; } this div contains icon acting link html <div id="nav">icon</div> i want div triangle (pointing towards right) , not square i find site useful: https://css-tricks.com/examples/shapesofcss/ right-facing triangle: #triangle-right { width: 0; height: 0; border-top: 50px solid transparent; border-left: 100px solid red; border-bottom: 50px solid transparent; } you can adjust border properties change width, height, , color of triangle. something you're looking for: https://jsfiddle.net/kh2xsoh2/1 html <div id="nav"><span>icon</span></div> css #nav { width: 0; height: 0; border-top: 25px solid transparent; border-left: 50px solid #000; border-bottom: 25px solid transparent; position: fixed; } #nav span

i understand reason why tmp needed in maildir : makes possible not have half-written mails in cur . however, why new needed? couldn't mails dropped cur folder directly name <uniq>: or so? mua wants add flags, initialize uniq part. make things (well, tiny) bit simpler code.

i try add column date of last revision , use code. there wrong here? thing is, doesn't work, doesn't give me error message add_filter('manage_pages_columns', 'add_revised_column'); add_action('manage_pages_custom_column', 'echo_revised_column', 10, 2); function add_revised_column($columns) { $columns['revised'] = 'revised'; return $columns; } function echo_revised_column($column, $id) { if ('revised' == $column) echo get_post_field('post_modified', $id); } this looks fine me in general. similar add media height x width dimensions on manage media page, , code pattern identical. but: recommend create constant, , use throughout avoid issue, eg: define('col_name_revised','revised'); ... $columns['col_name_revised'] = 'revision info'; ... if (col_name_revised == $column) ... edit : had answered key-names mismatched, on re-visiting question realised not m

var favoritecolor = "blue"; function colorgenerator(color) { return function () { return color; }; } var getcolor = colorgenerator(favoritecolor); why getcolor not blue. getcolor() blue. getcolor becomes function? because return function in colorgenerator? i confused these. thank help. let's dissect this: var favoritecolor = "blue"; function colorgenerator(color) { return function () { return color; }; } this method returns function that, in turn, returns value ( color ). doing this: var getcolor = colorgenerator(favoritecolor); means getcolor function() {return "blue";} . therefore, doing: getcolor(); after setting value return "blue" . test: var favoritecolor = "blue"; function colorgenerator(color) { return function () { return color; }; } var getcolor = colorgenerator(favoritecolor); document.getelementsbyclassname("foo")[0].innerhtml = "colorgenerator r

goal: 4x ( 4.400000095 ) = 17.60000038 legal ops: integer/unsigned operations incl. ||, &&. if, while max ops: 30 return bit-level equivalent of expression x + x + x + x for floating point argument f. my code: unsigned 4x(unsigned uf) { unsigned expn = (uf >> 23) & 0xff; unsigned sign = uf & 0x80000000; unsigned frac = uf & 0x007fffff; if (expn == 255 || (expn == 0 && frac == 0)) return uf; if (expn) { expn << 2; } else if (frac == 0x7fffff) { frac >> 2; expn << 2; } else { frac <<= 2; } return (sign) | (expn << 23) | (frac); } as can guess, code not work. instead of quadrupling input, input doubled. don't know why since fraction , exponent being right / left shifted 2 instead of 1. im working single precision floating point values in 32 bit machines. some untested code - leave op. (gtg) the tricky bit dealing sub-normal numbers when *4 become norm

i have faced strange problem when trying run process hidden window - process run runs in hidden process, doing wrong? want run child process not hidden. process.start(path.gettemppath() + "cleanup.exe", path.getdirectoryname(application.startuppath); you can try creating object of process class below : process objprocess = new process(); objprocess.startinfo.useshellexecute = false; objprocess.startinfo.redirectstandardoutput = true; objprocess.startinfo.createnowindow = true; objprocess.startinfo.windowstyle = processwindowstyle.hidden; // passing batch file/exe name objprocess.startinfo.filename = string.format(strbatchfilename); // passing argument objprocess.startinfo.arguments = string.format(strargument); try { objprocess.start(); } catch { throw new exception("batch file not found processing"); }

when connect rdbms mysql using hadoop record db user-defined class extends dbwritable , writable. if our sql query generates n records output act of reading record user-defined class done n times. there way in can more number of records mapper @ same time instead of 1 record each time ? if understand correctly, think hadoop causes n select statements under hood. not true. can see in dbinputformat 's source , creates chunks of rows based on hadoop deems fit. obviously, each mapper have execute query fetch data process, , might repeatedly, that's still near number of rows in table. however, if performance degrades, might better off dumping data hdfs / hive , processing there.
