What significance does the parameter "begin" of urls yotube? - youtube

For example:
http://o-o.preferred.telemexperu-lim1.v3.lscache6.c.youtube.com/videoplayback?upn=N2EK-YTwdeU&sparams=algorithm%2Cburst%2Ccp%2Cfactor%2Cid%2Cip%2Cipbits%2Citag%2Cms%2Cmt%2Csource%2Cupn%2Cexpire&fexp=919321%2C901027%2C907217%2C907335%2C921602%2C919306%2C919316%2C904455%2C919324%2C904452&key=yt1&algorithm=throttle-factor&mt=1337382014&ipbits=8&itag=35&sver=3&signature=94D9344CEF1C28BB9BB5F8C51C1F409BE39329B2.69CAFFDDF1556B2A83200F45F173F6E0FB8DE2CC&source=youtube&expire=1337407932&ms=au&ip=190.0.0.0&factor=1.25&cp=U0hSTFRLVV9ITENOMl9MRVlKOnVubENtTm5YaDRH&burst=40&id=ea8d708a77758947&ptchn=MARVEL&begin=9724&ptk=disney&cm2=1
when we advance the video (in some cases) the case that the youtube player sends the parameter begin ... but not the number of bytes, then what is?
You can do some testing here:

Sorry for my english.
Thanx!

I believe it's the number of milliseconds from the start.

Can someone see what is wrong with this XIRR() computation in Google Sheets? (I have sent a request to Google ...)

Please review https://docs.google.com/spreadsheets/d/1cWIAdWylD5Mx8zP5gFwkSVkAYLwXuFopoH_9mi2tGWg/edit#gid=0. It contains some dates and corresponding investment amounts. My goal is to have XIRR() compute the rate of return. While it is obvious that the result must be negative, the cell C1, with the formula XIRR(B3:B16,A3:A16), produces a huge positive number.
Thanks in advance.
I just realized that I didn't provide a 3rd argument, rate_guess, in the original invocation of XIRR(). (Thanks to #player0 for prompting me). With rate_guess provided, the result is believable.

error in calculating beta in second order point wise mutual information

I followed this rule but my result didn't meet the result in the paper !
while n=9 , segma= 0.7 ,f(W1)=11
the result in the paper for beta1= 6 and my result= 1.67
what's the wrong with this ?
who know this algorithm,what's beta here refers to ?
The paper you posted gets the algorithm slightly wrong, so you shouldn't rely upon it. Try following along with the example in this paper instead:

Testing for Cursor Not Found Error in mongoid

When I was processing large number of data I ended up in Cursor Not Found Error in Mongoid. And I googled and came across the below link:
DBCursor mongodb
Now I'm using skip and limit function to process 100 data at once and continue till it reaches 7350, which is the count of my documents.
As it takes too long to produce Cursor Not Found Error. I wonder if there is any quick way I can test for occurrence of this error. Thanks in advance.
maybe killOp would work, i guess.

jFugue incorrectly parsing tempo

I'm using jFugue to parse a midi file and it will always parse the tempo incorrectly(I know that the tempo is 140 and it is saying that the tempo is 720). At first I thought that it might, somehow, be multiplying the actual tempo by some number and that's not it. The number it's giving me is somehow related to the tempo, but I don't know how. This whole thing is very confusing, any help would be greatly appreciated.
Here it says that if you're using a version of JFugue before 4.0, tempo is stored as microseconds per beat, which is 60000 / BPM
http://www.jfugue.org/javadoc/org/jfugue/Tempo.html
Correction:
The conversion information on that page is incorrect.
PPQ (pulses per quarter, or microseconds per beat) = 60,000,000 / BPM
