i'd attempting schedule liquidsoap streaming source played @ specific date , time in future. believe can accomplished using liquidsoap switch command i'm having trouble understanding documentation described here: http://liquidsoap.fm/doc-1.2.0/reference.html#switch is possible using liquidsoap? i'd nice if pass timestamp. i'm not sure can pass absolute timestamp switch , can pass time of day or week. see "time intervals" section: http://savonet.sourceforge.net/doc-svn/language.html i think best bet using playlist file rewritten via cron, or using request.dynamic custom external script determines play based on time. see documentation playlist here: http://savonet.sourceforge.net/doc-svn/reference.html#playlist

i format numbers strings in c# custom group/thousands separator , decimal separator. group , decimal separator can change based on user input use numberformatinfo object instead of hardcoded formatting string. code below gets proper separators, changes precision of number 2 decimal places, whereas want keep full precision of number , show decimal places when needed (so integer values dont have decimal places). how can achieve this? guessing need change "n" parameter, change what? double n1 = 1234; double n2 = 1234.5; double n3 = 1234567.89; double n4 = 1234.567; var nfi = new numberformatinfo(); nfi.numberdecimalseparator = ","; nfi.numbergroupseparator = " "; string s1 = n1.tostring("n", nfi); //want "1 234" "1 234,00" string s2 = n2.tostring("n", nfi); //want "1 234,5" "1 234,50" string s3 = n3.tostring("n", nfi); //correct output of "1 234 567,89" string s4 = n4.t

i have found code this: try { myclass.do().tostring(); } catch () { } which results in exception being thrown when do() returns null . could, instead, use (myclass.do() ??

since i'm not totally sure on level issue solved best, i'd summarise path went , things tried first: it's more or less $el (i think). as basic backbone examples state, started having $el defined within view, like invoice.invoiceview = backbone.view.extend({ el: $('#container'), template: .., .. }); it didn't feel right, view supposed know parent (=container). paragraph 'decouple views other dom elements' written on http://coenraets.org/blog/2012/01/backbone-js-lessons-learned-and-improved-sample-app/ ) puts words. following article's advice, switched passing $el on view while calling render() -method. example: $('#container').html( new winelistview({model: app.winelist}).render().el ); so far - render() gets called, while maybe shouldn't (yet). for example view asynchronously fetch es model in initialize() -routine. adding binding reset or sync (e.g. this.model.bind('sync', this.render, this) ) makes s

i don't meaning of firefox's behaviour when hitting f5 on asp.net page. i have dropdownlist (autopostback=true if significant) , change value "first value" (index 0, default) "second value" (index 1). page posts , filters lists. now, when hit f5 (or refresh button in address bar) dropdownlist keeps selected value in ui ("second value"), when debugging page_load() dropdownlist.selectedindex-property 0 instead of 1 leads manner dropdownlist selection , lists not fit. ispostback false when hitting f5. internet explorer resets @ least dropdownlist makes acceptable. imho best behaviour simple same request again when hitting f5 (with postback). i know familiar problem (for me bug in firefox, isnt it?), there workaround? thank you. no solution workaround: i store selected value of dropdownlist in cookie , set on every page_load.
