i'm trying grep gem list. list with bundlelist = `bundle show` result "gems included bundle:\n * cfpropertylist (2.3.1)\n * abstract_type (0.0.7)\n * actionmailer (4.2.3)\n * actionpack (4.2.3)\n" i like: => ["cfpropertylist", "abstract_type", "actionmailer", "actionpack"] when try grep on it, bundlelist.scan(/\*.*\(/) . result is: => ["* cfpropertylist (", "* abstract_type (", "* actionmailer (", "* actionpack ("] use lookbehind , lookahead instead: /(?<=\* ).*?(?= \()/ what means minimum thing preceded star + space , followed space + opening bracket .

may funny question, newbie in c# class program { static void main(string[] args) { int a; = convert.toint32(console.readline()); console.writeline(a); console.readkey(); } } i expected after typing character, these character written on new line in console, though these printed on 1 line. wrong? p.s. console.writeline("asd"); console.writeline("dsa"); this displayed expected: asd dsa every call of console.writeline() method prints new line. example take input , print input single time. you try instead: class program { static void main(string[] args) { int a; while(true) { = convert.toint32(console.readline()); console.writeline(a); } } } edit: included version uses char , console.read() seems more appropriate class program { static void main(string[] args) { char a; while(true) { = (cha

i have been asked job beyond sql skills little , having done research online, cannot quite find write solution done in sql server 2008 , not mysql. i have table need update specific names adding additional string after point whilst keeping rest of string right intact. e.g. current name = 'name - location - 0005' new name = 'name (west) - location - 0005' as can see need add text (west), have table lists codes (e.g. 0005) , need link clause update relevant names. so questions are: 1 - how can update name adding additional text @ set location (5th character), whilst maintaining whatever text right of names 2 - there way can sort of in check code, tried using contains table not full-text indexed. not massive issue can manually create update statement using each row within table, nice know add knowledge base. with of stuff can achieve this stuff ( character_expression , start , length , replacewith_expression ) select stuff('name - location

in git repository i've got quite lot of images (changing other vcs git out of question). part of images, duplicates different size, these created imagemagick. time time, have regenerate images, ok, however, though image didn't change [size same etc] git marks file modified. assume because of last modified dates, right? there chance, change way git tracks changes of images? there anyway add imagemagick's compare functionality? thanks, krystian edited i wrong, git avoid checking file content , prefer using faster methods described in related post: how git detect file has been modified? if files not modified, i'm not sure if understand well, maybe using git update-index --assume-unchanged might help. however not mean files not modified when re-run generation step, , should check git diff or follow advices of post how can diff binary files in git? but think problem not lie git , better review work-flow. can see 2 options: either not re-generate

i used plugin install crashlytics both ios , android applications. 1 difference noticed comes on portal fabric provides. ios there 2 environments, 1 test (green icon) , other production (normal icon). android not this. i attempted create 2 different environments adding following in application class fabric.with(this, new crashlytics()); if (constants.debug) { crashlytics.setstring("version", "production"); } else { crashlytics.setstring("version", "test"); } i thought create 2 different version did not anything. how create multiple environments android? in advance there no difference between release , debug other signature in android. don't think separate products there. did is, i've 2 flavors, 1 dev , other 1 main flavor goes google play. dev flavor has different package name, creates 2 different products in fabric itself, don't need if separate them package names.

i thinking simulate bank account transaction in dynamodb being nosql type database, use case suited dynamodb? or should stick sql based database? does know how banks handles this? use dynamodb or keep our transaction in separate table? a sql based system allows transactions across multiple tables, while dynamodb allows transactions @ individual item. however, there dynamodb transaction library java allows atomic transactions across multiple items @ expense of speed , substantially more writes per request. dynamodb support atomic counters , bank-account-like (the example on documentation page along line). dynamodb provides conditional writes can avoid type of race conditions when item attempted updated concurrently. could build suitable system on top of dynamodb? maybe, depends on specific requirements , how go implementing such system. said, dynamodb provide functionality outlined above address types of concerns arise when building such system.

how able keep space between inlined div elements without counting space 'pixels'? for example, i'm using margin-right (as padding between elements) counting pixels (the result shows off ugly, see jsfiddle, div element gets pushed down). #parent .child { position: relative; display: inline-block; height: 100%; width: 16.5%; background-color: green; margin-right: 15px; } jsfiddle basically, have first item floaten left , last item floaten right. know many of guys thinking, why not use feature 'justify'? i've tried using it, isn't option since amount of elements can (10, 5, 8, etc). help appericiated! edit: feature i'd achieve multiple elements (instead of having 1 row, there 2-16 rows. you can use text-align: justify . won't justify last line, can force new line pseudo-element: #parent { text-align: justify; background-color: red; } #parent:after { content: ''; display: inline

the picture layout want when hover, gets messed up. div's start shifting around , moving horizontally when next div italicizes. how can maintain exact layout 100% of time? .project-link { font-family: 'utopiastd'; color:#010202; font-size:5.6vw; white-space:nowrap; text-decoration:none; margin-right: 3%; line-height:125%; border-bottom: solid transparent 2px; } https://jsfiddle.net/zjkouzbo/1/ solution 1: you had right idea trying white-space:nowrap . keep first 2 links , keep them on 1 line, wrap them in parent element , apply white-space:nowrap parent element. if have on both anchor elements , parent elements, won't break lines in middle of link or between them. <div class="line"> <a class="project-link" id="one" href="#modal1">maru speaker design <span> (1) </span> </a> <a class="project-link" id="two" href="#modal2">lights — out &

i have code calculates length of bezier curves. i'm trying write unit tests it. other trivial cases (straight line beziers) don't know actual correct values lengths. i've looked online , been unable find any. does have info? i'm looking link table few rows containing 4 bezier control points , length, or possibly create couple of beziers in drawing program calculates length (i've tried using blender , inkscape info , they're quite complicated). solution. download pomax's bezier javascript code here , open html in web browser: <html> <head> <script src="bezier.js"></script> </head> <body> <script> curve = new bezier([4.0, 0.0, 4.0, 4.0, 0.0, 12.0, 16.0, 0.0, 12.0, 16.0, 0.0, 4.0]); document.write(curve.length()); </script> </body> </html> if want actual arc lengths test against, implement https://githu

i installed mingw following home page sourceforge , using mingw-get-setup.exe. installed g++ 4.8.1-4. gcc 4.8 supposed to support c++14 command-line switch, "unrecognized option" error. is bug mingw? gcc? can it? since know ask, want c++14 for-each loops. i'm using iterators now, for-each improve both readability , writability. edit: found out g++ build supports c++11, can use for-each. still no luck on c++14 support. g++ 4.8 not support c++14, mingw quite outdated when there more new versions of gcc. alternatives can use if want use c++11 or c++14 on windows gcc should using 1 of following options: https://msys2.github.io/ (uses mingw-w64 internally). http://mingw-w64.org/doku.php (it supports 32-bits too). http://tdm-gcc.tdragon.net/ .
