i pretty new android app development , develop app geofencing. under understanding, geofencing can related own database stored in device memory , has limitation 100 geofencing can used @ same time. (actually not sure if understanding right. if not, please correct me.) my question is: can store several lists of geofences in device , enable list want using app? so, can have more 100 geofences use less 100 @ same time. short answer: yes, can. i'm not sure exact space requirements don't see problem in saving several lists of 100 entries each. for more information on how save data in android i'd recommend looking @ this training module . don't have save data - keep in working memory , redownload lists every time. maybe make more sense in case, don't know.

in acceleo, when edit , save, say, generate.mtl , acceleo automatically generates generate.java class. java class can call dogenerate method external class generate model-based stuff. however, if there exception during execution, exception handled acceleo engine. i tell acceleo engine not handle exceptions , , realize error occurred. how possible? i've been thinking long time this, without success. last week, ran acceleo in standalone mode, java class instead of using pluging. it made me spend lot of time issues libraries, problems dependencies etc. got (i mean, it's hard work, patient). my surprise: when ran acceleo standalone failed, templates same. having many errors, plugin managing , plugin printing empty string result! running acceleo standalone, errors raise exception , main class prints stacktrace. so, if want manage errors yourself, recommend run standalone but... luck! :) i hope :)

i see number of posts on platform giving same solution not work me, here simple node program understand why still appears process requests 6 6 instead of setup in http.globalagent.maxsockets ? var http = require('http'); http.globalagent.maxsockets = 10; var express = require('express'); var app = express(); app.use('/', function(req, res, next){ console.log('request /'); settimeout(function(){ res.send('ok'); console.log('handled'); }, 2000); }); app.listen(3309); console.log('server up.'); thank much... it's not clear problem try solve, http.globalagent singleton http client , can't affect code in way.

i have followed post( http://sebastiandahlgren.se/2013/07/27/adding-lines-to-table-with-jquery/ ) , implemented add row , delete row functionality in jsp page. everything working fine except 1 problem. delete row button deletes row loaded during page load (say 30 rows). here code snippet function deleterow () { if (count != 1) { $("table#mytable").datatable().fndeleterow(count - 1); count--; } } i want allow rows dynamically added using addrow function of datatables plugin. how can issue solved. you'll need distinguish between pre-loaded rows , ones added dynamically in js code. possible solution add custom css class dynamically added rows only: function addrow() { var table = $('table#mytable').datatable(); table.fnadddata( [ '<input type="text" name="first_name_' + count + '">', '<input type="text" name="last_name_' +

i trying pull top 5%, bottom 5% , remaining out separate arrays , save average. code below. tg = 48000000 element float array tg.sort() pct = int(tg.size*0.05) high5 = tg[-pct:].mean() low5 = tg[:pct].mean() mid90 = tg[pct:-pct].mean() i'd appreciate suggestions on how speed up. actually don't need sort array. use partition method: tg = 48000000 element float array pct = int(tg.size*0.05) tg.partition([pct, tg.size - pct]) mean_low5 = tg[:pct].mean() mean_high5 = tg[-pct:].mean() mean_mid90 = tg[pct:-pct].mean() (code updated according jaime' comment)
