Hi Gunter, I think this problem started happening when I upgraded from Debian Wheezy to Debian Jessie. If nothing looks amiss in my code, it probably is a sound driver problem. But since it works 100% of the time in ogg123, I feel I must have missed some corner case. My audio driver is almost always active. I usually have my music player going in the background when I do my testing. The problem

...took me a while, but I eventually figured it out. What I needed to do was fill the buffer with more data before handing it off to ao_play. It requires lots of bookkeeping, pointer arithmetic, and a sufficiently large buffer. First, the bigger buffer. I just pulled this code from ogg123: #define PRIMAGIC (2*2*2*2*3*3*3*5*7) #define AUDIO_CHUNK_SIZE ((16384 + PRIMAGIC - 1)/ PRIMAGIC * PRIMAGIC) char convbuffer[AUDIO_CHUNK_SIZE]; const int convsize = AUDIO_CHUNK_SIZE; The loop is now more convoluted. Here's the old one, for reference: long bytes_read = 0; do { bytes_read = decode_vorbisfile...

Hi, I have a medium-sized (19MB) CSV file that I'd like to read into R. The read.csv() function seems to be a bit inefficient to deal with it, and I remember that using scan() with "what" options is better. However I'm unable to understand how to use it. The first few lines of the data look like:

Hi, This may actually be a theoretical question. When I tried to do the following: ########################################################## > colnames(rating.adclms) [1] "usage" "mileage" "sex" "excess" "ncd" [6] "primage" "minage" "drivers" "district" "cargroup" [11]

Hi, Suppose I use the following codes to read in a data set. ############################################### > rating <- scan("../Data/Rating.csv", + what = list( + usage = "", + mileage = 0, + sex = "", + excess = "", + ncd = "", +
