Dear R Helpers, I am trying to extract the modulus from divisions by a sequence of fractions. I noticed that %% seems to behave inconsistently (to my untutored eye), thus: > 0.1%%0.1 [1] 0 > 0.2%%0.1 [1] 0 > 0.3%%0.1 [1] 0.1 > 0.4%%0.1 [1] 0 > 0.5%%0.1 [1] 0.1 > 0.6%%0.1 [1] 0.1 > 0.7%%0.1 [1] 0.1 > 0.8%%0.1 [1] 0 > 0.9%%0.1 The modulus for 0.1, 0.2, 0.4 and 0.8 is zero, as I'd expect. But, the modulus for 0.3, 0.6, 0.7 an...

...: {"snapshot%5Bscreenshot%5D"=>#<File:/tmp/CGI8585.4>, "action"=>"create", "controller"=>"snapshots", "snapshot%5Bprocesses%5D"=>"", "snapshot%5Bscreenshot_temp%5D"=>""} It looks to my untutored eye like the query keys are getting double-quoted on upload. Anyone else seen this, or anything like it? The code driving mechanize looks like this: img = @form.file_uploads.find{|f| f.name == ''snapshot[screenshot]''} img_name = time + ''.png'' img.file...

...;s not likely to result in much cancellation. The alternative that I've been trying is to keep the tail at roughly 200 ms (within the range of recommended values), but then to buffer 10 or so frames in a queue, pulling out the oldest one when I make my call to speex_echo_cancellation(). To my untutored mind, it seems like this should work -- but some of the comments I've read in the documentation (like the one warning against using two different sound cards, because their clocks wouldn't be adequately synchronized) make me wonder if this is a fool's errand. Any thoughts on whether th...

Hello Folks, This is the long awaited (like 2 weeks) 0.3.12 release of Mongrel. This release has received heavier testing than previous releases and supports a whole raft of improvements to existing functionality plus some new stuff. For those not clued in, Mongrel is a web server written in (mostly) Ruby. Check the funny dogs and read the docs about it at http://mongrel.rubyforge.org/. The
