Hello, I have a dataframe w/ 3 variables of interest: transaction,date(tdate) & time(event_tim).

My question is: Can I do it one single rsync command, giving a file containing list of paths as parameter, or do I need to run rsync for each file. I did not find any option doing it in the man page. I tried to play with

I hadn't noticed any interactive slowdown, but when I got around to running the notmuch performance suite, there seems to be some noticable slowdown with the glass backend (default in Xapian 1.3.5) compared to chert (using xapian 1.2.22) These tests are on an older i7 with 12G of RAM and an SSD. I'm reasonable confident they are CPU bound. One curious thing is the increase in system time

Then I decided that it would be good to be able to change order of the photos so that thumbnail pages would look less chaotic. So I created a Layout model which is a join model (or whatever it is called) that

Hi, I am getting the same problem of divided by zero while decoding in the function multicomb(). I am using fixed point speex code.

In transferring a kernel to a client using tftpd-hpa, is there any way to track down the source of the error message, "PXE-T02 Access violation"? All the files in /tftpboot have root ownership and 644 permissions, and this works fine if I use an etherboot-derived floppy to start the boot process.
