c# - Parallel.For, max threads and cores -

-
on our server, got quad-core processor. when running parallel.for loop without paralleloptions parameter, how many threads utilize? also, when running nested loops, should both outer , inner loops parallel or outer in terms of performance? you can't know how many exactly, number of threads between 1 , n , n number of tasks run in parallel (one thread current thread of execution way, since parallel waits tasks complete). parallel not guarantee operations run concurrently however, may be. implement own task scheduler , use if want control on how many threads used. if want know whether better run outer , inner loops in parallel, there no answer. don't know loops doing. use performance analyzer before trying optimize loops, since odds have no idea performance bottlenecks are.

pymongo - Using JSON in Python to send query to MongoDB -

i'm trying create following query in python connection have mongodb. db.deal.find({"id":"11223|14589"}) by using writing following code: import json unique_id = "11223|14589" query = json.dumps({"id":"%s"}) %(unique_id) unfortunately, creates string, , results don't returned results mongodb. querying manually using string created in variable query returns results. know might working pymongo? not sure you're trying achieve here. first of all, should not have serialize json. not replace parts of string after it's serialized . second, unique_id 1 value you're looking for? if so, pass query: unique_id = '11223|14589' foo.find({'id': unique_id}) or these 2 values you'd search for? unique_id = '11223|14589' ids = unique_id.split('|') # ['11223', '14589'] foo.find({'id': {'$in': ids}})

javascript - keydown (repetition) breaks when keyup event (for ANOTHER key) is fired -

-
this bit of weird 1 figure i'm either missing obvious or flaw how these events implemented in browsers. let me first summarize example scenario issue comes before providing isolated case-example; the arrow keys used move player (as handlekeydown function fired anytime key hit anywhere on page). likewise, anytime key released function fired (handlekeyup). as (the player) hold left key down, handlekeydown function repeatedly triggered (which admittedly think defies you'd expect , name implies, nonetheless, normal behavior across browsers i'm sure know). so here's happens: player holds direction walk in direction; press number key (for hot-keyed item) continue walk while holding direction down. happens here release number key hot-keyed item, repetition player movement stops! i've written small isolated example of behavior: <html> <head> <script type='text/javascript' src='jquery-1.5.1.min.js'></script> ...

yii - How to specify image paths in CSS files? -

-
i'm using yii framework , have css file uses images background , similar. other php code can use yii::app()->request->baseurl prefix resources correct path. however, css file not php, cannot use code. i tried relative paths, same css file accessed html pages of different depth, example: http://mysite/controller/action1/10 http://mysite/controller so relative paths don't work (at least, not in browsers). is there yii-way of doing this, or should use absolute paths , done it? the paths images in css files relative css file, not page referencing css file. so shouldn't matter using css file in html pages @ different path depths, looks location of css. for example, if css file in /content/css , images in /content/images should reference images url(../images/something.png) .

portal - Use SAP Logon ticket with .Net Application using SSO22KerbMap or SAPSSOEXT -

-
i looking option on using single sign on (sso) sap portal non-sap asp .net application. reading through documents , online searches, found there couple of approaches 1. use "sapssoext" evaluate logon ticket in .net application. 2. use "sso22kerbmap" isapi module. the .net application configured use integrated windows authentication using active directory. but, need support sso sap portal. without sso, if user signs .net app user b's system, .net app windows authentication , treat user b logged in user. option 1 involves developing new code .net application not support , may not possible in case. option 2 sounds promising, not clear on how work. sounds module verifies sap logon ticket , acquires constrained kerberos ticket. but, confused how .net application use constrained kerberos ticket. option 2 seamless bridge install , .net app support sso magic? love if did that, sounds true. :) any pointers helpful understanding.
