i new using docker, , got doubt of using 1 image base stack or have define each image depending on needs. example, reading blog creating website using docker author suggests following stack: image taken http://project-webdev.blogspot.de/2015/05/create-site-based-on-docker-part4-docker-container-architecture.html now, seen structure, if have base images in docker registry technologies mongodb, io.js, nginx, why on examples not use images insted of using single docker base image everything? i'm author of blog post/series, let me elaborate on reason why i've chosen 1 base image. :) docker offers possibility use common base image subsequent images, can stack images , each image contains diff underlying image (that's big advantage of docker!). can save disk space , ram. if don't care (i mean ram , storage cheap) can use multiple images. another advantage of 1 base image can configure/secure base image based on needs. if use different base image each cont...

in general, there reason still use int opposed long in java if programming on 64 bit architecture? specifically in case: i use int variables being mapped keys(sequential numbers starting 1 , incremented each new entry) of type number on oracle db table. the db type number has way more precision int correct way model on java side long . i stuck int efficiency reasons , because never have many entries in table need more int can represent. on other hand, since modern machines 64 bit anyways, shouldn't make difference regarding efficiency on java side use long opposed int , right? guess make difference memory wise if load huge lists of keys memory not doing kind of operation. on 64-bit processor, long give marginal performance boost because of alignment, registers, whatever (whether or not palpable debatable). comes drawback of using more space on stack , heap, impact performance negatively. really, depends on program, since there many factors impact pe...

how nginx flushes buffer access_log default ? in manual there not info, setup syntax: access_log path [format [buffer=size [flush=time]] [if=condition]]; did bit of research on myself, , far can tell nginx doesn't flush buffers @ if not specify flush parameter. (or if does, it's more 20 minutes.) the exception if restart server, logs flushed before restart. so if specify buffer should make sure specify flush time too.

i'm wondering whether idea use hashes (cityhash, murmur , like) keys in key-value store hazelcast. i'm expecting have 2,000,000,000 records (urls) in database, collisions happen. wouldn't super critical lose data through hash collisions, of course best avoid them. a record contains url, time stamp, status code. main operations inserting , looking whether url exists. so, suggest, given speed relevant: using id generator , or using hash algorithm cityhash or murmur, or using relevant string, url in case, itself? hazelcast not rely on hashcode/equals methods of key object, instead using murmur hash of binary representation of key. in short, should not worry hash collisions.

after moving wordpress website 1 server have encountered odd issue. works great, until go edit post or page , presented empty content box on backend. (see image). all of posts , pages displayed on front end except there strange characters in content (see image). if try republish post, empty content saves on hidden content , post becomes empty on front end. i disabled plugins , switched themes changed nothing. did corrupt database on transfer or there other reason might have caused this? has else run this? the problem turned out db_charset , db_collate both set '' in wp-config.php. updated them following values , issues resolved: define('db_charset', 'utf8'); define('db_collate', 'utf8_general_ci');

i wrote simple program mistake use scanf() instead of printf() displaying message on console. expecting compile time error, compiles fine without warnings & crashes @ runtime. know scanf() used taking input keyboard. shouldn't error in following program? #include <stdio.h> int main() { scanf("hello world"); // oops, had printf() return 0; } is invokes undefined behavior(ub)? there mention in c standard? why isn't checked @ compile time whether proper & valid arguments passed scanf() function or not? the code behaving correctly. indeed, scanf declared int scanf(const char *format, ...); luckily, format not contain % there no correspondence in ... , invoke ub. further, format string literal allows compiler go through ensuring passed right type of parameters in regards format specifiers, part of sanity checks enabled higher warning levels.

i have data needs classified in spark streaming. classification key-values loaded @ beginning of program in hashmap. hence each incoming data packet needs compared against these keys , tagged accordingly. i realize spark has variables called broadcast variables , accumalators distribute objects. examples in tutorials using simple variables etc. how can share hashmap on spark workers using hashmap. alternatively, there better way this? i coding spark streaming application in java. in spark can broadcast serializable object same way. best way because shipping data once worker , can use in of tasks. scala: val br = ssc.sparkcontext.broadcast(map(1 -> 2)) java: broadcast<hashmap<string, string>> br = ssc.sparkcontext().broadcast(new hashmap<>());

i using ng-flow drag & drop files , upload server. page developing has multiple drop listeners . there way detect on element drop occurred ? <body ng-app="droptest" flow-init="{target:''}"> <div name="drop1" class="fa fa-paperclip fa-rotate-90 cell small" flow-drop="" title="drag/drop files upload record"></div> <div name="drop2" class="fa fa-paperclip fa-rotate-90 cell small" flow-drop="" title="drag/drop files upload record"></div> </body> $scope.$on('flow::fileadded', function (event, $flow, flowfile) { //how detect whether drop occured on drop1 or drop2? }); i figured out $scope.$on('flow::fileadded', function (event, $flow, flowfile, elementdetails) { elementdetails.target });
