ASP.NET MVC 4 and ContextDependentView -

-
i have started playing beta , discovered bit of black magic in there. when @ _loginpartial.cshtml line builds register link says: @html.actionlink("register", "register", "account", routevalues: null, htmlattributes: new { id = "registerlink", data_dialog_title = "registration" }) the link rendered on browser says /account/register . however, form in register view renders action /account/jsonregister based on viewbag.formaction value. value set? have suspicion it's contextdependentview returned register action can't quite figure out how or why. any ideas please? the real magic in ajaxlogin.js file, modifies link add content=1 querystring parameter used in contextdependentview decide whether send json form or regular form. this jquery stuff people don't bother at.

entity framework - Code First for SQL Server 2005? -

-
my development db 2008 r2 code first generates local database dropcreateifmodelchanges. my method of deploying production generate scripts local db, including data , run in production. creates of tables, including edmmetadata table , populates hash. works: run script in different 2008 r2 instance, change connection string entity model point production instance, run application. does not work: run script in different 2005 instance, change connection string entity model point production instance, run application. error indicating model has changed. i think doesn't work because db compatibility version part of hash. in production generates hash , compares hash stored in edmmetadata table. new hash different because generated against 2005 db. i guessing not have problem if generating 2005 db locally , deploying 2005 production instance. don't have 2005 installed , rather not require developers have install it, when 2008 supports 2005 compatibility mode already.

xml - Python ElementTree find() not matching within kml file -

i'm trying find element kml file using element trees follows: from xml.etree.elementtree import elementtree tree = elementtree() tree.parse("history-03-02-2012.kml") p = tree.find(".//name") a sufficient subset of file demonstrate problem follows: <?xml version="1.0" encoding="utf-8"?> <kml xmlns="http://www.opengis.net/kml/2.2"> <document> <name>location history 03/03/2012 03/10/2012</name> </document> </kml> a "name" element exists; why search come empty? the name element you're trying match within kml namespace, aren't searching namespace in mind. try: p = tree.find(".//{http://www.opengis.net/kml/2.2}name") if using lxml's xpath instead of standard-library elementtree, you'd instead pass namespace in dictionary: >>> tree = lxml.etree.fromstring('''<kml xmlns="http://www.opengis.net/kml

Programmatically, how does hue blending work in photoshop? -

-
in photoshop can set layer's blending mode "hue". if layer is, example, filled blue seems take layer below , makes blue wherever non-whiteish color exists. i'm wondering it's doing though. if have background layer pixel aarrggbb , layer on top of set blend mode "hue" , there's pixel aarrggbb on layer, how 2 values combined give result see? it doesn't drop rrggbb layer below. if did it'd color white , black well. wouldn't allow color variations through. if background pixel 0xff00ff00 , corresponding hue layer pixel 0xff0000ff i'm assuming end result 0xff0000ff because ff blue replaces ff green. but, if background pixel 0x55112233 , hue layer pixel 0xff0000ff, how come shade of blue comes with? the reason ask i'd take various images , change hue of image programmatically in app. rather storing 8 different versions of same image different colors, i'd store 1 image , color needed. i found algorithm convert rgb

Java - Convert Unix epoch time to date -

i need convert epoch time stamps real date , have used of methods found on stack overflow, give wrong answer. as example, 1 date "129732384262470907" in epoch time, "mon, 20 jan 6081 05:24:22 gmt" using http://www.epochconverter.com/ however, code generates: "wed dec 24 14:54:05 cst 19179225" string epochstring = token.substring(0, comma); long epoch = long.parselong(epochstring); date logdate = new date(epoch * 1000); bufferedwriter timewrite = new bufferedwriter(new filewriter(tempfile, true)); timewrite.write(logdate); timewrite.flush(); timewrite.close(); the initial timestamp in miliseconds, in examples saw here supposed multiply 1000. if don't multiply 1000, get: "mon aug 08 01:14:30 cdt 4113025" both of wrong. so have made error? 129732384262470907 in microseconds since epoch if it's meant 6081, need divide 1000 if that's real input. note epochconverter.com doesn't handle value
