i asked question combine multiple mysql queries on same table one , received noteworthy answer @paul griffin . as stated in other question linked above, have multiple queries combined 1 query. these queries consist of exact matching , broad matching search terms. i searching through posts on wordpress website. keep things simple, i'm looking through following columns in posts table: post_title (article title), post_name (article url slug), , post_excerpt (article summary). just keep things simpler sake of question, let's have search term of "floor finish", , i'm searching through column post_title . as stated earlier, i'm looking exact matches , broad matches. so 3 searches placed: floor finish floor finish that produce query like: ( select `id`, `post_title` `tps_3_posts` `post_status` = 'publish' , `post_title` '%floor finish%' ) union ( select `id`, `post_title` `tps_3_posts` `post_status` = 'publish'

i'm starting use preprocessor css in case less css. i'm trying achieve loop padding. example less.org modified .generate-pad(10); .generate-pad(@n, @i: 1) when (@i =< @n) { .padd-top-@{i} { padding-top: (@i * 100px / @n); } .generate-pad(@n, (@i + 1)); } outputs following when compiled .padd-top-1 { padding-top: 10px; } .padd-top-2 { padding-top: 20px; } .padd-top-3 { padding-top: 30px; } .padd-top-4 { padding-top: 40px; } .padd-top-5 { padding-top: 50px; } .padd-top-6 { padding-top: 60px; } .padd-top-7 { padding-top: 70px; } .padd-top-8 { padding-top: 80px; } .padd-top-9 { padding-top: 90px; } .padd-top-10 { padding-top: 100px; } but trying replace .pad-top-@{i} variable can call later. how can achieve if possible in less.

i wish expand structure ( bac ) number of fields structure ( bt ). names of these fields contained in cell array ( adds ) strings. this have (and doesn't job, explaining post): for i=1:numel(adds) eval(genvarname('bac.',adds{i})) = eval(strcat('bt.',adds{i})); end i tried using sprintf , did not seem work me. feel confident 1 of knows how it, since feel should rather easy. the best way of doing use dynamic field names : for i=1:numel(adds) bac.(adds{i}) = bt.(adds{i}); end

i have scenario in rabbitmq setup i'm curious how solve. diagram below illustrates (exchanges , queues removed succinctness): scenario producer creates message a(1), received top consumer, begins processing message. producer creates message a(2), received bottom consumer (assuming both consumers on round-robin exchange). the bottom consumer publishes message b(2), put message b consumer's queue the poor slow top consumer finishes , emits message b(1). problem if assume b consumer cannot made idempotent, how ensure result of both b messages applied in correct order? i had thought of using timestamp applied initial publish of message a, , having consumer maintain timestamp of last change, rejecting timestamps before time, works if each message causes exact same kind of change , requires lot of tracking. other ideas how approach appreciated. thanks! i not sure specific rabbitmq here, idea timestamps sounds start if have single producer. the produ

i'm wondering have done wrong #n/a error i have k21 show agent's name worked on ticket appeared in k20 . have agent names listed in b3:b18 . columns have: c total, d type , e subtotal. ticket numbers logged column f3 , g , h , on each agent k20 has =min(f3:xfd18) determine oldest ticket. k21 has =vlookup($k$20,b2:g18,3,false) show agent's name logged oldest ticket. i'm bit confused you're asking sounds might using formula wrong. if wanting return agent's name oldest ticket make sure columns in correct order (a-lookup value,b-agent name,c-other variable). using format can try k21=vlookup($k$20,a2:b18,2,false) ----where a2:a18 has value looking , 2 second column (b) , has agent's name.

if understand correctly, can not run nutch 1.8 , 1.9 hadoop job, because these versions not have crawl class serves wrapper crawl steps. means there no 1 class can specify in hadoop call run whole job. in nutch 1.7, used org.apache.nutch.crawl.crawl class. am missing something? 1 figure out way around this? your understanding wrong. should use script bin/crawl. in each step, should see corresponding class should call (in case want use outside crawl script). in addition, far know class quoted deprecated.

i'm attempting insert api response mongo db, doesn't save individual fields. input here playerslist.insert(meteor.http.get("api call here")); here response call: {"hnub": { "id": 21098134, "name": "hnub", "profileiconid": 20, "revisiondate": 1428613578000, "summonerlevel": 30 }} is there simple way cleanly saving fields? the response of http call object content (string), data (javascript object if can parsed json), headers, , statuscode. recommend run code see actual response: console.log(meteor.http.get("api call here")); if turns out response includes parsed json under data field, accomplish want with: playerslist.insert(meteor.http.get("api call here").data); note, synchronous way of making api call work server. @ethaan points out, you'll need use callback client , you'll have overcome cross domain restrictions.

i'm parsing http headers. want split header values arrays makes sense. for example, cache-control: no-cache, no-store should return ['no-cache','no-store'] . http rfc2616 says: multiple message-header fields same field-name may present in message if , if entire field-value header field defined comma-separated list [i.e., #(values)]. it must possible combine multiple header fields 1 "field-name: field-value" pair, without changing semantics of message, appending each subsequent field-value first, each separated comma. order in header fields same field-name received therefore significant interpretation of combined field value, , proxy must not change order of these field values when message forwarded but i'm not sure if reverse true -- safe split on comma? i've found 1 example causes problems. user-agent string, example, is mozilla/5.0 (x11; linux x86_64) applewebkit/537.36 (khtml, gecko) chrome/41.0.2272.101

i'm using matlab's import data code generator pass data series of commands. works fine when run script , reference single file, if loop through several files, variables aren't updated expect. believe have traced problem 'fileid' not updating after first iteration of loop. in code below, can confirm 'filename' updated each iteration of loop, while 'fileid' not. consequently, same vector assigned variable 'y' in each iteration. can suggest going wrong? filelist = dir('*.csv'); n = size(filelist,1); k = 1:n % file name: filename = filelist(k).name; delimiter = ','; startrow = 2; %% format string each line of text: % column2: double (%f) % column3: double (%f) % column4: double (%f) % column5: double (%f) % more information, see textscan documentation. formatspec = '%*s%f%f%f%f%[^\n\r]'; %% open text file. fileid = fopen(filename,'r'); %% read columns of data according format string. dataarra

in acumatica want compute "quote expires" date on sales order entry form based on date new order of type "qt" created. date computed adding default "default quote expiry days" set in sales order preferences. example if default expiry days = 45 (setup) , order created on april 1, 2015 default date "quote expires" on sales order entry form may 16, 2015 (april 1, 2015 plus 45 days). expiry date may overridden user. any examples appreciated. protected virtual void soorder_usrexpireddate_fielddefaulting(pxcache sender, pxfielddefaultingeventargs e) { soorder row = e.row soorder; if (row.orderdate.hasvalue) { e.newvalue = row.orderdate.value.adddays(45); } } for example added custom field soorder called usrexpireddate, feel free replace number 45 kind of setup.

i've been trying feels days remotely connect sockjs-go ( https://github.com/igm/sockjs-go ) server application i've written. i'm developing locally on windows, , works fine. when try running on remote linux server (after building on linux box, obviously), never able connect sockjs server. i've tried running example echoserver web example sockjs-go repository on remote machine, , cannot connect either. i made sure change sockjs client ip local machine remote machine. i have right public ip address , can view static web page served lighttpd. i've tried searching on google golang-specific, have found nothing. suggestions great. update i using echo test code verbatim given here: https://github.com/igm/sockjs-go/tree/v2/examples/webecho as far can tell, linux server isn't filtering. port 8080 closed before running webecho, , open after starting webecho. i have tried https://coderwall.com/p/wohavg/creating-a-simple-tcp-server-in-go , can conn

i trying study php , came across if statement has single variable conditional this: <?php if($a){ //do } ?>; i know c++ , javascript, in languages, if statement ben invalid. tell me if statement means? as rizier123 said above, conditional checking "truthy" values in variable $a. in loosely-typed language php, truthy value non-empty, non-null, or non-zero value. see great answer similar question: https://stackoverflow.com/a/6693908/2796449 or php docs: http://php.net/manual/en/language.types.boolean.php boolean logic reduces down entire statement down 1 value, either true or false. executing "echo (3==4);" show false. if variable returns truthy value, evaluated true. these 3 comparable statements: $a = 1; if ( $a ) if ( 1 ) if ( true )

say page import of domain in gsp, example: <%@ page import="com.sample.entity.book" %> to use page via <g:select from="${book.list()}" optionkey="id" optionvalue="title" name="booksample"/> is bad programming practice use import? new grails , have seen practice in lot of tutorials, lead discourage me because according him hackers can data db. i've been arguing against guess need support. i agree on above more ideal use controller list of books - think not idea using <%@ page import="" %> bad coding because makes page vulnerable. i know gsps compiled , no reference of import visible html pages. update: thank giving inputs. i've updated question give more focus. if told wrong , reason - kind of think beyond best practices , more on security, can't imagine how, through import i'm not sure "hackers bad things" reasoning, there bett

i new c# , trying kill list of processes. able use code below kill 1 process change kills list of processes. on time list grow ideally find way updating list quick , easy. try { foreach (process proc in process.getprocessesbyname("notepad")) { proc.kill(); } } catch (exception) { console.writeline("procces not found."); } i'm sorry if have overlooked question asked this. thank in advance provided. the observablecollection<t> class provides event if collection changed. can create collection of process , handle new added items in event handler: observablecollection<process> processes = new observablecollection<process>(); processes.collectionchanged += processes_collectionchanged; static void processes_collectionchanged(object sender, notifycollectionchangedeventargs e) { if (e.newitems != null) foreach (var process in e.newitems.oftype<process>()) process.kill(); pro

(some of code has been removed, such plotting code, doesn't affect issue) as title states, i'm having issue numpy's sum function rounding nearest integer. in following code, create variable chisqrr using np.sum, works intended, giving value of 1.23727.... near bottom of code, have practically exact same code need find bunch of values 'chisqr' based on range of input values. 3 lines of interest are: chisqr[i] = np.sum(((counts - fit_exp_nonlin(t, popt[0], mu[i], popt[2]))/yerr)**2) print(((counts - fit_exp_nonlin(t, popt[0], mu[i], popt[2]))/yerr)**2) print(chisqr[i]) where first 'print' line, without np.sum command, gives bunch of values (all of long decimals), however, once summed np.sum, exact integers, not possible. example, 1 array before it's summed is: [ 0.2251407 0.25516322 0.90413181 1.08316468 7.40191331 0.00893473 1.94594874 0.24967999 2.58848903 1.39550592 0.06140513] and 'sum' gives array is: 16 whereas i

how convert input text 'abcde'f gh' to output 'abcdefgh' ? this did not work. a='abcde'f gh' b=a.translate({(u"\u0027"):none}) you should escape apostrophe ' or use quotes " define string: >> a='abcde\'f gh' or >> a="abcde'f gh" to remove symbol ' , spaces, use string.translate this: >> b = a.translate(none," \'") 'abcdefgh' string.translate(s, table[, deletechars]) delete characters s in deletechars (if present), , translate characters using table, must 256-character string giving translation each character value, indexed ordinal. if table none, character deletion step performed.

i have 2 arrays: var underarray = ["_", "_", "_", "_", "_"] , var letterarray = ["a", "b", "c", "d"] . have button, , every time press button want replace element of underarray 1 letterarray . for exmple: first press: var underarray = [a, _, _, _, _] second press: var underarray = [a, b, _, _, _] third press: var underarray = [a, b, c, _, _] etc... i can manually like: underarray[0] = letterarray[0] , underarray[1] = letterarray[1] , that's not option. so far tried creating - loop , did not work: @ibaction func mybuttons(sender: uibutton) { var index = 0; index < underarray.count; ++index { swap(&underarray[index], & letterarray[index]) } } i suspect it's wrong approach. right approach? you have declare variables out of ibaction , make sure don't in case button has been pressed many times: var presscounter = 0 var und
