i want keep browse history, to calculate behaviour among browsing pages. so designed following graph show idea, as can see, there 4 edges between page a , page b , so how create kind of relationships , nodes ? how average browsing time ( 20min ) min browsing time max browsing time any suggestion , ideas? thanks i'm bit confused. relationship mean? represent amount of time spent on page before user browses page b? just going model , goals, maybe work? match (a:page)-[r:browsed_to]->(b:page) return avg(r.time_spent) for min , max time replace avg min , max

i have actor goes (assume receive method overridden somewhere else): class myclass extends actor { def method1() = { ... } def method2() = { ... } def method3() = { this.synchronized { .... .... } } } what happens if have final field defined in actor as: private val locktype = new anyref i can use lock synchronize method3? difference? understanding using reference lock on method make reference unavailable until lock released. in above case, use lock can function independently of reference , lock when action on method3 made, while reference still available other threads? there's no need synchronization inside of actor. actor ever process single message @ time.

by default, oozie shared lib directory provides libraries hive, pig, , map-reduce. if want run spark job on oozie, might better add spark lib jars oozie's shared lib instead of copy them app's lib directory. how can add spark lib jars (including spark-core , dependencies) oozie's shared lib? comment / answer appreciated. spark action scheduled released oozie 4.2.0, though doc seems bit behind. see related jira here : oozie jira - add spark action executor cloudera's release cdh 5.4 has though, see official doc here: cdh 5.4 oozie doc - oozie spark action extension with older version of oozie, jars shared various approaches. first approach may work best. complete listings anyway : below various ways include jar workflow: set oozie.libpath=/path/to/jars,another/path/to/jars in job.properties. this useful if have many workflows need same jar; can put in 1 place in hdfs , use many workflows. jars available actions in workflow. th

findone() : if multiple documents satisfy query, method returns first document according natural order reflects order of documents on disk. i need similar effect above, except if multiple documents satisfy query, returns 1 comes earliest in $or array. db.collection.findone({ $or: [ {"apple": "blah"}, {"orange": "blah"}, {"grape": "blah"} ] }) for example, if these documents satisfy above query [ {"apple": "....", "orange": "....", "grape": "blah"}, {"apple": "....", "orange": "blah", "grape": "...."} ] it returns document matched orange (the second 1 above), because orange comes before grape in $or array. similarly, if document matched apple document returned because apple comes earlier in array. how can done? it sounds want assi

i'd current clock speed. search results suggest wmi. problem is, doesn't work. example, overclocked cpu test (increased 200 mhz). cpu-z reported correctly, 4.2 ghz. wmi incorrectly reported @ 4.0 ghz (the stock max clock speed). i've noticed system properties doesn't report clock speed right. assume pulling data using wmi. understand cpus don't run @ highest clock speed. in circumstance, running @ highest clock speed (according cpu-z). the reason want figure out compare current clock speed, , max clock speed (to determine if cpu overclocked in application). here's example of code. imports system.management public class form1 private sub button1_click(sender system.object, e system.eventargs) handles button1.click dim cpuspeed string = string.empty dim wmiobj managementobjectsearcher = new managementobjectsearcher("root\cimv2", "select * win32_processor") each element managementobject in wmiobj.get() cpuspeed =

confused little on ruby. know makes .rb files, make exe or com files or used as web application? i know bit writing code, files after. the question bit broad. you have step , @ how source code in general ends being executed (i.e. used). in case of programming languages (e.g. c/c++) it's compiled native form , can executed directly afterwards; in case of other languages it's compiled intermediate form (e.g. java/c#) , executed vm (jvm/clr) in case of yet other languages interpreted @ runtime (e.g. ruby/python). so in specific case of ruby, have interpreter loads rb files , runs them. can in context of standalone apps or in th e context of web server, have interpreter making sense of ruby files. don't executable same way languages compiled machine code.

i've looked on internet finding complicated results , im not sure do. sublime text 2 has builtin java support: which means once have opened java source, have press command+b what described in comments bit different - should update post information! devin posted gist solution here : you should add new build-system going menu: tools --> build system --> new build system and add following json , save "java.sublime-build" default directory (which like: ~/library/application support/sublime text 2/packages/user/ ): { "cmd": ["javac", "$file_name"], "cmd": ["java", "$file_base_name"], "working_dir": "${project_path:${folder}}", "selector": "source.java" } next time want compile & run use "java.sublime-build" build-systems.

i wondering how generate random numbers appear in circular distribution. i able generate random points in rectangular distribution such points generated within square of (0 <= x < 1000, 0 <= y < 1000): how go upon generate points within circle such that: (x−500)^2 + (y−500)^2 < 250000 ? first answer: easy solution check see if result satisfies equation before proceeding. generate x, y (there ways randomize select range) check if ((x−500)^2 + (y−500)^2 < 250000) true if not, regenerate. the downside inefficiency. second answer: or, similar riemann sums approximating integrals. approximate circle dividing many rectangles. (the more rectangles, more accurate), , use rectangle algorithm each rectangle within circle.

i'm trying use enum object in class cant figure out have done wrong. here lines of code in first class trying reference second class. model model = new model(); model.outcome outcome = new getgameoutcome(uchoice,cchoice); and here actual object trying reference in "model" class. public enum outcome{ win,loss,tie } public outcome getgameoutcome(string uchoice, string cchoice){ and continues rest. you aren't creating new instance, assigning return value of method. hence, not need new operator: model.outcome outcome = getgameoutcome(uchoice,cchoice);

could explain difference between cache memory , scratchpad memory? i'm learning computer architecture. a scratchpad place keep stuff. cache, memory talk through not talk at. scratchpad post note, write on , keep you. cache paper send off else instructions memo. cache can in various places, layers (l1, l2, l3...). both scratchpad , cache sram in chip, address , data bus , read/write/etc control signals. (as many other things in computer may or may not used addressable ram). during boot, before ram on far side (slower ram side, processor being near side) initialized (eventually dram typically if have cache otherwise why have cache) may possible access cache addressable ram. depends on system/design though, there may control register enables behave simple ram, or there may mode, or normal mode may such long dont address more size of ram based on alignment (perhaps 32k ram between 32k boundaries) may not try evict , generate bus cycles on dram/slow/far side of ca

i'm implementing payments platform website wich similar stripe, still can't understand process or how should use webhooks since need specify 1 on account in payments platform. so let's person pays in website product costs $5, take them payment form introduce credit card details. when click "pay now" gets verified via javascript/jquery , sent server , i'm able charge user , see reflected on sandbox account on payment platform. or when should webhooks used or called, or why need them? thanks in advance webhooks way communicate application. many apis, send them request , api response included in response request. if request make asynchronous, or if reason api you're using wants able communicate application calling directly opposed waiting make request. with webhooks, you'd open endpoint on application other api / service can send requests can process requests. can think of push notifications web applications. with payments standard u
