Android get layout name where string is used -

is there way layout string used. example: "submit" string used in registration layout. how can know it? you've asked half question i'm making assumptions that talking in code , ide - not runtime that correctly store strings in strings.xml that using android studio (and windows) open strings.xml, click key (name) part of resource , press alt + f7 find usages. alternatively if need full text search press ctrl + shift + f7 search whole project find in path edit address comment to find view "submit" text using espresso can use either of these lines onview(withtext("submit")); onview(withtext(r.string.submit));

ssl - cipher suite specs using TLSv1.2 only and no SSLv3 TLSv1.2:!aNULL:!eNULL -

when using vpn-like connection between 2 servers (not web servers or it), besides authentication enable encryption. the authentication portion working, wanted @ encryption level. i know tlsv1.2 , v1.1 supported alongside wih sslv3. i use tlsv1.2 , nothing else. tlsv1.2:!anull:!enull is the correct cipher suite use? information https://www.openssl.org/docs/manmaster/apps/ciphers.html seems not helpful... can this matter? i use tlsv1.2 , nothing else. if want use tls 1.2 have configure protocol , not ciphers. limiting ciphers tls 1.2 ciphers drops support ciphers available since ssl 3.0 , still supported tls 1.2. depending on peer might end no shared ciphers way. if still want restrict ciphers might try string tlsv1.2:!anull:!enull . make use ciphers newly introduced in tls 1.2 , implicitly enforce protocol. again, no guarantee server supports these ciphers if server can tls 1.2 protocol.

javascript - Get number of image files and switching between them -

i've directory containing few image files [for example 4 files], want number of images existing in directory , show first image , allow users switch between images using controller elements , show number of image showing between it. example: i've 4 images , page shows first image , text " << 1/4 >> " , when user clicks on next button shows next image , text changes " << 2/4 >> " , ... can show me foundation of work? mean can tell me i've (not needed attach codes). use angularjs in page now, if it's needed can use jquery ( if it's not possible using angularjs ). this html page although think it's not helpful: <?php require ('functions.php');mob_check(); ?> <!doctype html> <html lang="fa-ir" data-ng-app="projects" data-ng-controller="projects_controller">  <head> <!-- adding meta...

revert - Git: Reset to old commit -

i know question has been answered couple of times, far, every posted solution tried did not work me :( the situation is: have working commit in master branch want go to. unfortunately, multiple changes (including merges other branches) have been pushed master since then. so need master branch last working commit again - or checkout last working commit , "overwrite" last commits on master - on server (github) repo. don't care if changes made last working commit lost, wouldnt hurt if kept intact. important other branches not touched!!! git revert did not job in multiple ways... we can try replacing master branch new branch, fishy :) create new branch working commit know if commit nth level down head use git branch master-temp head~n . replace n level. if have commit hash use git branch master-temp <sha1> rename current master branch new name master-old or master-deprecated rename new branch master-temp master this remain changes, c...

sql - Matching cells that contain hexadecimal range -

i trying query rows column 1 contains string of pretty random elements. however, last two-three elements of string hexadecimal value or decimal (0-255), like: column 1 | column 2 00000587-8bb4-4360-9b0b-79012c14aa6d | 1 00000541-1895-4b13-9de2-7be77dda5de6 | 2 000005db-da97-483d-9efb-69222bbc7b57 | 3 i need rows column 1 contains string ends hexadecimal values ranging e6 f2 or 0-255 normally use where acc.accountid ilike '%e6' , repeat values in range there has more efficient way? the hardcore way be: select * my_table ('x' || substring (col1 length(col1) - 1))::bit(8)::integer between 50 , 200

to experiment hyper, started the example . aside fact example doesn't compile ( no method `get` in `client` ) have distilled problem single line: fn temp() { let client = client::new(); } this code won't compile: unable infer enough type information `_`; type annotations or generic parameter binding required [e0282] in general error mean client has generic parameter , compiler can not infer it's value. have tell somehow. here example std::vec::vec : use std::vec::vec; fn problem() { let v = vec::new(); // problem, vec<???> want? } fn solution_1() { let mut v = vec::<i32>::new(); // tell compiler directly } fn solution_2() { let mut v: vec<i32> = vec::new(); // tell compiler specifying type } fn solution_3() { let mut v = vec::new(); v.push(1); // tell compiler using } but hyper::client::client doesn't have generic parameters. sure client trying instantiate 1 hyper?

c++ - Calculation of euler angles -

i need understanding math behind code. x component of returned vec2 , y component of returned vec2. can explain me represent. know function determinate position of vector in sphere coordinates. glm::vec2 calceulerangles(const glm::vec3& vec) { glm::vec3 v = glm::normalize(vec); glm::vec2 result(acos(v.z), atan2(v.y, v.x)); while (result.y < 0.0) result.y += twopi; return glm::vec2(glm::degrees(result.x), glm::degrees(result.y)); } it calculating spherical coordinates phi , theta unit vector. the first component ( phi ) angle between vector , z-axis. second component ( theta ) angle on xy-plane. assumes vector can expressed follows: x = cos theta sin phi y = sin theta sin phi z = cos phi if solve this, calculations in function. adding 2 pi y ensures angle between 0 , 2 pi .

"simplified time: " + (hours + ":" + minutes + ":" + seconds + ":").replaceall("^(0:){1,2}", ""); ^(0:){1,2} regex means ^ represents start of string (in our case start of x:x:x: since replaceall applied part), prevents matching 0: in middle of string if there no 0: before it,...

multithreading - How does RAM is shared in multi core environment? -

i learnt multi core processors have more 1 processing units( i.e. main executing units alu etc.) , better @ performance. want know how share physical memory. i'll take following example make question clearer - say, there memory location m in physical memory , 2 threads t1 , t2 running on different cores. possible t1 , t2 access m @ same instance of time or have wait 1 other complete access i.e. share same memory bus have wait, 1 or can read m @ same instance of time 2 different memory buses? if former case, there not performance gain right, have wait memory bus free? summarising, memory operations independent of other cores or each core can make physical memory access when memory bus free? memory access depends on ram module , not on cpu , cpu cores can request access access given first , depends on ram itself!
