you came here chide me real use case. in world of online education, there scorm courses. have make old scorm courses work on site. scorm courses "web based" , run in browser, expect run in iframe , expect parent supply getvalue method , setvalue. so these scorm courses doing things parent.setvalue("score", "90") , moving on. function supposed return "false" if there issue. scorm comes 90's, , in modern web know have callbacks/promises , http fails "often". might think solution setvalue writes local data , tries , retries until get's through, scorm course typically set move next screen if setvalue worked, shouldn't letting user advance unless setvalue saved on server. tl;dr assuming syncronous request requirement, right way it? so far know of $.ajax({async:false ... browsers warn , sound they're going ignore request synchronous. thinking maybe using websockets or web workers or right way syncronous...

how can format date dd/mm/yyyy or mm/dd/yy ? like in vb format("dd/mm/yy",now) how can in c#? it's same, use datetime.tostring() method, e.g: datetime.now.tostring("dd/mm/yy"); or: datetime dt = getdate(); // getdate() returns date dt.tostring("dd/mm/yy"); in addition, might want consider using 1 of predefined date/time formats, e.g: datetime.now.tostring("g"); // returns "02/01/2009 9:07 pm" en-us // or "01.02.2009 21:07" de-ch these ensure format correct, independent of current locale settings. check following msdn pages more information datetime.tostring() method standard date , time format strings custom date , time format strings some additional, related information: if want display date in specific locale / culture, there overload of tostring() method takes iformatprovider : datetime dt = getdate(); dt.tostring("g", new cultureinfo("en-us")); // re...

using ffmpeg, why bitrate shown during processing differs final bitrate after processing? this command on 1080p source: ffmpeg -i "$name" -i "$subname" -map 0 -map 1 -vf scale=-1:720 -c:v libx264 -preset veryslow -crf 21 -c:a aac -b:a 256k -c:s:0 srt -disposition:s:0 default -metadata:s:s:0 language=eng -metadata:s:v:0 title="$title" "$new" shows output: which averages 1300-1400 kbit/s. when calculate bitrate of resulting video using mkvinfo -t bitrate shown sits @ ~970-1000 kbit/s , that's not close averaging ~1300 kbit/s shown throughout processing. causing disparity? from documentation of mkvinfo: mkvinfo -t show statistics each track in verbose mode. i guess, see bitrate video track, while ffmepg output average bitrate whole mkv (audio track + video track). difference notice round 300kbit/s near audio bitrate, 256kbit/s
