i'm developing application using java & mysql database, application desktop application working in network environment. application has static content loaded database when starting application. if super user made change variables, need enforce network users restart application can load new variables. what idea or code need use. you implement this. observer pattern or maybe can have "configtable" in database, property, value, expiration time. so, when admin updates value, other applications in network can pool new value. take jgroups regarding pooling approach, (we don't have enough information give best solution) try this. a notification_table id, event (event know, maybe load new images, etc) workflow 1) clients pool table every x seconds, filtering id > lastnotificationid (that needs saved in local file) 2) client applies new events. 3) client updates local file new notificationid.

i have small issue, want merge object , array map function. code is: var headers = [{ "name": "date", "dtype": "date", "dtitle": "inserta date" }, { "name": "patient", "dtype": "text", "dtitle": "insert patient name" } ]; var rows = [ [1, 2], [3, 4], [5, 6] ]; var c = 0; var item = []; var items = []; rows.map(function(v) { v.map(function(a) { h = headers[c]; h.value = a; item.push(h); c++; }); items.push(item); c = 0; }); console.log(items); finally duplicate last record rows array. don't know made mistake. try use _ each , loop same result. i want receive result ex: result = [ [ { "name":"date", "dtype":"date", "dtitle":"inserta date", "valu...

how integrate amazon cloud front , s3 in photo sharing application? i upload s3, , return cloudfront url has not been successful because appears there latency between s3 , cloudfront such returned url not valid. does know how can work around this? facebook uses akamai , if upload image available. would appreciate ideas on this. you must trying fetch object immediately through cloudfront. i'm unsure why might be, hitting limits of s3's eventual consistency model . when upload object, message takes tiny amount of time propagate across s3 service. under 1 second , hard detect. (in previous life job, found reasonably guarantee files arrived within 10 seconds, , 99.9% within 1 second) here's official word aws; it's worth reading whole page : a process writes new object amazon s3 , lists keys within bucket. until change propagated, object might not appear in list. there's longer discussion on stackoverflow question ; assuming using stand...

like window or osx, docker-machine used start linux env, make not installed. have makefile pull/build/start docker, not run. how solve this? the boot2docker vm based on tiny core linux , install package use tce-load : docker-machine ssh <profile> tce-load -wi make to search packages can use interactive tce tool.

for example, have set formula find xnew[k+1], ynew[k+1] , anew[k+1] . how pass value 3 1 matrix if want index 1,1 xnew[k+1] , index 1,2 ynew[k+1] , index 1,3 anew[k+1] . here's got far. for (k = 0; k < 5; k++) { xnew[k+1] = cx + (t * mpcv[k]) * math.cos(ca); ynew[k+1] = cy + (t * mpcv[k]) * math.sin(ca); anew[k+1] = ca + (t * mpcw[k]); double[,] qk = new double[3, 1]; int i, j; (i = 0; < 3; i++) { (j = 0; j < 1; j++) { qk[i, j] = 1; } } } thank help. suposing xnew[k+1] , ynew[k+1] , anew[k+1] doubles: for ( k = 0; k < 5; k++ ) { xnew[k + 1] = cx + (t * mpcv[k]) * math.cos(ca); ynew[k + 1] = cy + (t * mpcv[k]) * math.sin(ca); anew[k + 1] = ca + (t * mpcw[k]); double[,] qk = { { xnew[k + 1] , ynew[k + 1] , anew[k + 1] } }; } this make 1x3 matrix (arrays start in 0) with: qk[0,0] = xnew[k+1] qk[0,1] = ynew[k+1] qk[0,2] = anew[k+1] but if want ...
