iam searching command line takes text file , file line numbers (one on each line) (alternatively stdin) , outputs lines first file. the text file may several hundreds of mb large , line list may contains several thousands of entries (but sorted ascending) in short: one file contains data another file contains indexes a command should extract indexed lines first file: many lines of course different , contain important data ... more lines ... more lines second file 1 5 7 expected output many lines more lines more lines the second (line number) file not have exist. data may come stdin (in deed optimum). format of data may vary shown if make task easier. this can approach: $ awk 'fnr==nr {a[$1]; next} fnr in a' file_with_line_numbers file_with_data many lines more lines more lines it reads file_with_line_numbers , stores lines in array a[] . reads other file , keeps checking if line number in array, in case line printed. the trick use...

we have appengine app, has 300gb of data in hrd.. performed full backup google-cloud-storage every night. has become costly, costing 100 dollar per day. i moved backup once per week. since data in hrd (high replication datastore)... there need backing data? we cannot afford losing data of more day. thats why did daily backup. costs 100 dollar per day. regarding hrd, iare backups needed? recommend. i know business question too, has technical aspects. data stored in hrd replicated in various regions, there no need perform backups, unless you're afraid data can modified / deleted via app or developers console.

i have job takes while complete , quite resource heavy. ever want run 1 instance of job @ time, , if there new scm changes. i set scm trigger , left off checkbox "execute concurrent builds if necessary". the problem have queues next build on first scm change detects. what want whenever scm trigger sees change, replaces job queued new job, newer scm revision. don't want running new instance next change, , don't want ton of jobs queued up. basically, want job run in loop, , pause if there no scm changes. how do that? you might looking quiet period option under advanced project options section. you can set value (in seconds ) quiet period per requirement. reduce frequency of builds.

8 bits representing number 7 this: 00000111 three bits set. what algorithms determine number of set bits in 32-bit integer? this known ' hamming weight ', 'popcount' or 'sideways addition'. the 'best' algorithm depends on cpu on , usage pattern is. some cpus have single built-in instruction , others have parallel instructions act on bit vectors. parallel instructions (like x86's popcnt , on cpus it's supported) fastest. other architectures may have slow instruction implemented microcoded loop tests bit per cycle ( citation needed ). a pre-populated table lookup method can fast if cpu has large cache and/or doing lots of these instructions in tight loop. can suffer because of expense of 'cache miss', cpu has fetch of table main memory. if know bytes 0's or 1's there efficient algorithms these scenarios. i believe general purpose algorithm following, known 'parallel' or 'variable-precision...

i run problems solved automating code writing, aren't long enough justify tediously entering each piece faster. here example: putting lists dictionaries , things this. converting b. a hotdog hd hamburger hb hat h b def symbolizetype case self.type when "hotdog" return "hd" when "hamburger" return "hb" when "hat" return "h" end sure come automatically, make sense if list 100+ items long. list of 10-20 items, there better solution tediously typing? ruby example, typically run cases time. instead of case statement, maybe it's dictionary, maybe it's list, etc. my current solution python template streaming input , output in place, , have write parsing , output code. pretty good, there better? feel vim macro excel at, i'm experienced vim. can vim easily? i frequently, , use single register , macro, i'll share. simply...

say want target specific letter in textbox region , replace letter using either jquery or javascript, how , still able target letter afterwards, , again, , again etc.? letter change , changed inputed either textbox or dropdown (whichever easier) p.s tried jquery's replace function , didn't work (i didn't use correctly though :) $( "button" ).click( function() { $( "changed" ).replacewith( $( "new" ) ); }); $("button").click(function() { var old = $("#changed").val(); var replacement = $("#new").val(); var regexp = new regexp(old, 'g'); $("#input").val(function(i, current) { return current.replace(regexp, replacement); }); }); you need use # before ids select them. you need values of inputs using .val() . jquery's .replacewith replacing entire dom elements, not changing value of input. you use .val() change value of input. when ar...

i wondering if possible allow people write , execute php code website without use of "eval" due risks. have googled around , did find answers, not answers looking (call_user_func). not looking not allow people run full php script. it's small group of people executing server load not issue. edit 1: users should not able corrup/delete files; users should able create complete scripts.; users should able run html code trigger php php tags used. you can write own wrapper process around php uses ptrace control execution of child php process prevent opening file handles, connecting network, etc. that way, if people decide try using malicious code in eval, system calls blocked on native level.

i have next problem. trying rotate 3d model around 3 axis @ same time. meaning want rotate model around x axis, y axis, again x , forth pressing buttons on keyboard. problem when use xmmatrixrotationx, xmmatrixrotationy or xmmatrixrotationz this: void rotate(float radians_x, float radians_y, float radians_z) { directx::xmstorefloat4x4(&_transfer.world, directx::xmmatrixtranspose(directx::xmmatrixrotationz(radians_z))); directx::xmstorefloat4x4(&_transfer.world, directx::xmmatrixtranspose(directx::xmmatrixrotationy(radians_y))); directx::xmstorefloat4x4(&_transfer.world, directx::xmmatrixtranspose(directx::xmmatrixrotationx(radians_x))); } only last rotation gets done. want able rotate object around each of axis specific angle (actually, radians), can see in code. have found out xmmatrixrotationaxis method this, takes 1 angle parameter, , want use different 1 each axis. can me how can done? also, don't know send first paramet...

i'm trying use tinymce (version 4.1.2) wysiwyg editor. logged in users can write own pages , see directly shown on page when visitor visits. now, i'd html stored directly. example: the logged in user sees this text! , in fact tinymce displays <p>this text!</p> . there's styles <h1> , links can added. now, user can insert hyperlink, giving link , text should displayed. problem however, if user manually write <a href='example.com'>example</a> , shows in editor gets stored in pure html well, when displaying hyperlink text example . this how code sort of looks (left out configuration): tinymce.init({ setup: function(editor){ editor.on('change', function(e){ $('[name="'+editor.id+'"]').next("textarea").html(editor.getcontent({format: 'html'})); }); } }); so text tinymce field gets copied <textarea> inside <form> gets submit...

i trying set different figure size in different chunks. first define global settings using: opts_chunk$set(fig.width=7, fig.height=7) then, specific chunks, use: opts_current$set(fig.width=7, fig.height=14) but later neglected. so, how opts_current work? for specific code chunks, put chunk options in chunk header, e.g. ```{r fig.width=7, fig.height=14} these called local chunk options, override global chunk options (temporarily specific chunk).
