i think idea turn off multiple statements prevent type of sql-injection. example of multiple statements: $query = "update authors set author=upper(author) where id=1;"; $query .= "update authors set author=lower(author) where id=2;"; $query .= "update authors set author=null where id=3;"; pg_query($conn, $query); is possible prevent multiple statements in posgresql settings or example using posgre's related php code? or maybe there way of parsing sql queries before passing them pg_query in order detect queries consists of more 1 statement? no, there no way disable multi-statements in postgresql. nor, far know, there way in php pg or pdo postgresql drivers. they aren't problem anyway. disabling multi-statements might (slight) sql injection harm mitigation , wouldn't real protection. consider writeable ctes, example, or qualifier removal attacks. instead, protect code in first place. rigorously use parameterized statements...

i'm pretty new php. first time actually, apologize in advance if question sounds dumb. i have php script fetches data external api , updates database regularly. know best way use cron job. however, using infinite loop sleeps particular time between each update. now, need allow user (admin) start / stop script , allow them change time interval between each update. admin through ui. best way this? how execute script in background when user clicks start , how stop script? thanks. i think ideal solution following: have background job run cronjob every minute (instead of loop can cause memory leaks). php not designed daemon. set db flag in cronjob on/off, everytime runs checks if on or off, if off exists if on continue. in ui turn flag on or off depending on admin needs. i think best way go (and easiest).

i web rest api service i've decided return datetime data string timezone looks this: "somedate":"2012-01-23t22:52:37.039+02:00" wonder, how idiomatic it? if returned unix time stamp, more sensible? personally, prefer using unix timestamps in situations because timezone agnostic , leaves timezone interpretation entirely client. additionally, depending on client, it's less code parse unix timestamp date date string, that's ancillary consideration.

can't find discussion around that. in javascript, there way detect i'm running different functions in same execution block or have executed function in current execution block? basically need optimize browser code avoiding run twice in same synchronous block. i'm doing this: var issaved = false; function saveuistate() { if(issaved === true) { return; } // heavy dom processing ... issaved = true; settimeout(function() { // reset flag in execution block issaved = false; }, 0); } but i'm not guaranteed flag reset before next execution block. although node's process.nexttick more appropriate, i'm more looking way identify execution block: var lastexecutionblockid; function saveuistate() { if(lastexecutionblockid === executionblockid) { return; } lastexecutionblockid = executionblockid; ... } you may want research mediator pattern, think in situation. subscribe calls...

while (it.isvalid()) { simpleattributeset s = (simpleattributeset) it.getattributes(); linkurls = (string) s.getattribute(html.attribute.href); if (linkurls != null) { system.out.println(linkurls); } it.next(); } this loop shows urls. how display getresponsecode () each address? must done in loop? can write such code? not know how go it. you're going need open urls, warned relative or protocol-relative (unless library you). once rebuild url, do url url = new url(urlstr); // might idea validate connection type before casting httpurlconnection connection = (httpurlconnection)url.openconnection(); connection.getresponsecode();

edit : dropped , waited few days started working! how upgrade 1.6 took while 'propagate'! shrugs . chimed in! the queryset filter month not seem working correctly. have bunch of objects in database model called note field pub_date storing datetime object. want retrieve note objects month. here test did: >>> blogengine.models import note >>> n = note.objects.all()[0] >>> n.pub_date datetime.datetime(2014, 3, 8, 21, 15, 14, tzinfo=<utc>) >>> note.objects.filter(pub_date__year = 2014) [<note: note object>, <note: note object>] >>> note.objects.filter(pub_date__month =3) [] as can see year works correctly, giving me 2 objects year=2014 , month lookup returns nothing though there object month can seen first example object n . happens other datetime lookups day or minute . python = 2.7.5 django 1.6.2 so dropped , waited few days started working! how upgrade 1.6 took while 'propagate'! ...

i'm using comparehist() function compare histograms of 2 images. my question is: size of image has considerable influence on results? should resize images or normalize histograms before comparing? i'm using cv_comp_correl method. you have normalize histograms before comparision. imagine have non noramlized histograms, e.g. 1 of them has bins values in interval [0..1000] , other in [0..1]. how can compare them? of course every mathematical operation addition makes no sense, because result of addition? then in practice size of image not matters. in practice means if hava image , scale lets 2 times , you've got image b, if compute hist(a) , hist(b), normalize both histograms practically same. because of fact if scaling image factor k, , have n pixels in color c in image a, in image b have approximately k*k*n pixels in color c (depends of interpolation). every color amount "scale" proportionally, if normalize hist(a)and hist(b), results approxim...
