is common give translator xliff contains html? do cat tools support html tags properly? <trans-unit id="1" xml:space="preserve"> <source>this &lt;b&gt;bold&lt;/b&gt;</source> </trans-unit> update: i'm working on html5 wysiwyg editor widgets, , need have export translation feature. have @ xliff 1.2 presentation guide html . ideally need encapsulate html elements in xliff elements this: <g id='d' ctype='bold'>bold</g> . most cat tools support native xliff elements treat escaped html plain text, cause issues.

i have regex track signups site. there multiple adresses goal. here regex: (\/membership\/signed-up\/|\/membership\/campagin\/(?!.*(not-this-campaign)).[-\w]+\/signed-up\/) i want match adresses: /membership/signed-up/ /membership/campagin/random-campaign/signed-up/ /membership/campagin/other-random-campaign/signed-up/ but want exclude address: /membership/campagin/not-this-campaign/signed-up/ it works, google matches address: /membership/signed-up/step-2/ when test in http://regexr.com matches on strings want, why google analytics matching more? try : (\/membership\/signed\-up\/(?!.*(step\-2))|\/membership\/campagin\/(?!.*(not\-this\-campaign)).[-\w]+\/signed\-up\/) you regex correct, but, need ensure dont match step 2

i have code randomly generates 10 pixel locations in image dimensions. want take each pixel location , find gbr value , find largest g value, b value, r value , smallest g value b value , r value. found code can take color boundaries , create mask image. might want incorporate mean g, b , r value , compute standard deviation each , use eliminate outliers. or instead of using code wrote generate 10 random pixels if there way color range inside of +- 1 standard deviation of mean color of image? see code below: import cv2 import numpy np import random name = "highway" img = cv2.imread(name + ".jpg") inc = 10 n = 10 rpixel=[] # grabs bottom center of image, keeps image ratio. larger inc smaller imaged grabed def bottomcenter(inc,img): y,x,z = img.shape h = x/2 x1 = h - (x/inc) x2 = h + (x/inc) y1 = y - (y/inc) y2 = y bcsample = img[y1:y2, x1:x2] return(bcsample) # generates random selection of pixels def randompi

i had problems installing gem, tried updating cocoapods. uninstalled first, tried installing again command sudo gem install cocoapods , gem install cocoapods. won't work because had following error: error: error: while executing gem ... (errno::ehostdown) host down - sendto(2) "8.8.8.8" port 53 this happens when gem install cocoapods , sudo gem install cocoapods. idea why happens ? connection internet ok. tried searching on internet possible solutions couldn't find similar one. never mind, using little snitch blocked incoming connection :)

i have slider 100 images , want extract height of each of parents (the wrapper) use inline onload event: <div class="wrap" style="height: 100%"> <img src="<%=i.src%>" style="width: 100%; max-height: 100%" onload=" var maxheight = $(this).parent().height(); console.log(maxheight)"> </div> i can correct readings on image height . problem parent .wrap element. strange thing half of images log right height (almost first half of them log 0 height , other half log correct height ) , if wrap javascript inside settimeout function can see more time use more logs correct height until time logs correct. know has timing of load event, time fires shouldn't rendered because i'm trying father's height ? so: 1) why happening? 2) how make work?

i have develop sdk web service android, should consider using okhttp creating instead of httpurlsconnection? if benefits of using it? you should try both if in learning phase. libraries make work alot easier. list down libraries used in making network call. retrofit library - easy intergrate , fasten network call official link . use peer library picasso if downloading images. use okhttp if need http operations lie outside of retrofit/picasso. volley library - officially supported google check this i recommned use retrofit simple use , documentation nice. pros of retrofit: compared volley in rest api code brief , provides excellent api documentation , have support in communities! easy add projects. can use serialization library, error handling.

given map<class1, class2> , want store in format: [{ key: ** key encoded using class1 codec **, value: ** value encoded using class2 codec** }, { ... }, { ... }, ... ] since it's supposed work class1 , class2 , not know how implement mongodb codec , getencoderclass function ( encode , decode not problem) far know, not handle generic types. how can define , register such codec? or there easier way that?

i unsure whether should , perform bitwise operations , division inside opengl fragment shader, or before running shader (calculate in c++ , pass uniform). i'm doing converting hex int representing rgb value color can used drawing in opengl. faster [on systems]? if single value calculated per draw call, in c++. gpus insanely fast, there's little point in getting them calculate same value millions of vertices or fragments. however, there's question of how data passed around. if suspect there's difference, try both approaches , profile them.

i have sourcetable 2 column names: col 1 | col 2 ------------------ | 2 b | 3 c | 4 d | 2 e | 1 f | 0 the first column has letter, , second column carries frequency. we need write stored procedure , output in targettable this. we can not use loop, or iteration this. col 1 ----- b b b c c c c d d e how recursive cte? with x ( select col1, 1 i, col2 lim t col2 > 0 union select col1, + 1, lim x + 1 <= lim ) select col1 x order col1;

how can calculate time based on different location's time in react native app? example, user in new york , want app convert time user inserts , convert based on location's time (which given in lat/long) , send server store in db. time in advance. since default date.now() give time based on phone's timezone, suggest using momentjs has feature utc time (more on docs ). the default use be: const = moment(); and in order avoid timezones , utc time: const = moment.utc();

documentation gctrimcommitonlowmemory says: because garbage collector retains memory future allocations, committed space can more strictly needed. can reduce space accommodate times when there heavy load on system memory. reducing committed space improves performance , expands capacity host more sites. when gctrimcommitonlowmemory setting enabled, garbage collector evaluates system memory load , enters trimming mode when load reaches 90%. maintains trimming mode until load drops under 85%. when disable both gcserver , gcconcurrent . each web site (worker process) eats between 100 , 500 mb. when concurrent server gc enabled, web sites eats between 1500 , 2500 mb. since there more 100 such web sites memory load gets on 200 gb (physical memory full). i thought enabling gctrimcommitonlowmemory (while both gcserver , gcconcurrent enabled) causes web sites return unused memory gen 0 heap size when server reaches 90 % memory load. however, seems not return (the ser

i write code solve kind of equations: for wrote code below, not solve problem. have ideas possibility solve kind of integrals in r? t_0 = 15 mu = 0.1 lambda = 0.8 f = function(x1,x2) exp(mu*(x1+x2))*dexp(log(lambda)*(x1+x2)) f_comp = function(x2) f(x1,x2) f_1 = function(x1) {integrate(f_comp,upper = t_0, lower = x1)} result = integrate(f = f_1, lower = 0, upper = t_0)$value --------- edit: given answer below, adapt code example, still think not correct one, @ least value 0 integral not make sense. integrate(function(x1) { sapply(x1, function(x1){ integrate(function(x2) exp(mu*(x1+x2))*dexp(log(lambda)*(x1+x2)), lower = x1, upper = t_0)$value }) }, 0, t_0) by way, buid general procedure (that why not calculate integral hand). not double integrals, n-tuples integrals, need general procedure kind of calculations.
